The technical field to which the invention relates.

The present invention relates in General to a communication system using a multiple access scheme, and in particular, the device and method of transmitting/receiving data using a multiple access scheme based on the scheme of orthogonal multiplexing frequency division.

The level of technology

With the introduction in the late 1970's in the U.S. cellular communication system, mobile South Korea began to provide services for voice communication in analog communication system, mobile first generation (1G), usually referred to as a system of communication with mobile objects storing UMTS (the ADR methods) (advanced mobile phone service). In the mid-1990s, South Korea has deployed a communication system, mobile second generation (2G)system called mobile communication multiple access, code-division multiplexing (mdcr, CDMA), for voice and low speed data transfer.

In the late 1990s, South Korea has partially deployed system for mobile communication of the third generation (3G), known as the system of mobile communication (IMT-2000 (international mobile telecommunication-2000 (after 2000)), aimed at improved wireless multimedia service, R is using worldwide (automatic connection to the local network) and the maintenance of high-speed data transmission. Communication system, mobile 3G was developed primarily for data transfer at a higher speed along with the rapid growth of data.

Communication system, mobile 3G develops in a communication system, mobile fourth generation (4G). Communication system, mobile 4G corresponds standardization for effective integrated service between wired network and wireless network beyond simple wireless service, which provides mobile communication system objects of previous generations. From this it follows that for wireless networks must be developed technology to transfer large amounts of data, reaching the level of bandwidth available in the network wired connection.

In this regard, there is an active study on the scheme of orthogonal multiplexing frequency division (OMCR, OFDM), useful for high-speed data transmission over wired/wireless channels in the communication system, mobile 4G. Scheme OMCR, transmitting data using multiple carriers is a special case of modulation schemes with many carriers (TNM, MSM), in which a serial symbol sequence is converted to parallel symbol sequences moduliruetsya many mutually orthogonal subcarriers (or subcarriers).

The first system TNM appeared in the late 1950's for high-frequency (HF) radio communications in military applications, and the scheme OMCR for overlapping orthogonal subcarriers was originally developed in the 1970's. Due to the orthogonal modulation between multiple carriers diagram OMCR has limitations in a real embodiment for systems. In 1971, Weinstein (Weinstein) and others have suggested that the modulation/demodulation OMCR can be done efficiently using the discrete Fourier transform (DFT, DFT), which was the driving force behind the development of schemes OMCR. In addition, the introduction of interval protection and cyclic prefix in the interval protection is additionally softens the adverse effects of multipath propagation and delay distributed via systems. In the communication system OMCR transmitting symbols OMCR, enter the interval protection to eliminate interference between symbol OMCR transmitted in the previous time at which characters are transmitted OMCR, and the current character OMCR transmitted in the current time of transmission symbols OMCR. For the interval protection scheme is used cyclic prefix" or " the scheme "cyclic Postfix". In the scheme of cyclic prefix specified number of last samples in the symbol OMCR the time domain are copied and then inserted in the effective symbol OMCR and cyclic Postfix the th scheme specified number of first samples in the symbol OMCR the time domain are copied and then inserted in the effective symbol OMCR.

For this reason, the scheme OMCR was widely used technologies for the digital message data type digital broadcasting (CVD, DAB), digital TV broadcasting, wireless local area network (BLS, WLAN), and wireless asynchronous transfer mode (BARP, WATM). Although the complexity of the equipment represented an obstacle to the wide use of schema OMCR, recent advances in the technology of digital signal processing, including fast Fourier transform (FFT) and inverse fast Fourier transform (OBPF, IFFT), provide the ability to implement the scheme OMCR. Scheme OMCR similar to the existing scheme of multiplexing frequency division (CDM), boasts the optimal transmission efficiency during high-speed data transmission because it transmits the data to the subcarriers, while maintaining orthogonality between them. Optimal transfer efficiency is additionally attributed to the good efficiency of frequency use and sustainability relative to fading due to multipath propagation in the scheme OMCR. In particular, to the efficient use of frequencies and stability of the relatively selective fading in the frequency and fading due to multipath propagation results in overlapping frequency spectra. Scheme OMCR reduces the effects messing the selected interference (MAI, ISI) using intervals protection and provides the opportunity to design a simple structure hardware equalizer. In addition, since the scheme OMCR resistant to impulse noise, it is becoming increasingly popular in communication systems.

In conclusion, an improved system for mobile communication 4G takes into account both the software for the development of various content and hardware design of the wireless access with high spectrum efficiency, to ensure the best quality of service (QoS).

Now will be described below hardware is covered in the communication system, mobile 4G.

Wireless high-speed, high-quality data transmission in General is hampered due to poor environmental conditions of the channels. In a wireless communication environment channels often change due to changes in the power of the received signal due to the fading phenomenon, the shielding, the Doppler effect caused by movement and frequent changes of speed of the mobile station, and interference caused by another user and multipath signal, as well as additive white Gaussian noise (abgs, AWGN). Therefore, to ensure high-speed Wi-Fi Internet access is ne transmission of data packets needed an improved method, capable adaptive to cope with the variation of the channel, in addition to the technologies provided in the existing system of mobile communication (2G or 3G). Even though high-speed circuit power control, adopted in existing systems may be adaptive to cope with varying channel, the partnership Project 3rd generation (3GPP), the organization of asynchronous standardization for standardization system high-speed packet data, and the partnership Project 3rd generation 2 (3GPP2), the simultaneous standardization, usually offer a scheme of adaptive modulation and coding (AMC, AMC) and hybrid automatic request retransmission (GASP, HARQ).

First of all, here will be described the AMC scheme.

The AMC scheme adaptively adjusts the modulation scheme and the coding scheme in accordance with the variation of the channel downlink (from base station to mobile unit). The base station can detect information about the quality of channels (IRC, CQI) of the downlink, the total measuring signal-to-noise ratio (SNR, SNR) of the signal received from the mobile station. That is, the mobile station transmits the channel feedback information about the quality of channels downlink to the base station for uplink communication (from the moving object to a base station). B. the gas station estimates the channel downlink, using information about the quality of channels downlink transmitted on the feedback channel from the mobile station, and adjusts the modulation scheme and the coding scheme in accordance with the estimated channel state.

In a system using the AMC scheme, such as the access pattern of packetized data over high-speed downward communication line (DPWNS, HSDPA), the proposed 3GPP, or scheme lx extended transaction data and the speech signal (lxEV-DV), proposed 3GPP2, when the channel state is relatively good, uses a modulation scheme of high order and high speed encoding. However, when the channel state is relatively poor, uses a modulation scheme of a low order and low encoding speed. Usually, when the channel state is relatively excellent, there is a high probability that the mobile station is in a location near the base station. However, when the channel state is relatively poor, there is a high probability that the mobile station is located at the cell boundary. In addition to the factor of the distance between the base station and the mobile station, an important factor affecting the state of the channel between the base station and the mobile station, is also time-varying characteristic of the type of fading channel. The AMC scheme compared to existing the scheme, dependent on high-speed power control, improves the average efficiency of the system by increasing adaptability to time-varying characteristics of the channel.

Secondly, here will be described the scheme GASP, in particular N-channel scheme GASP stop and wait (GASPP the Reis, SAW HARQ).

In the overall scheme of automatic resend request (ASP, ARQ) signal handshaking (acknowledgment) (KVIT, ASC) and packetized data retransmission exchanged between the user equipment (or mobile station) and the controller of the radio communication network (DAC RNC). However, in order to increase the efficiency of transmission schemes ASPP, in the scheme GASP recently started to use the following two methods. First, is exchanged resend request and response between the user equipment and node B (or base station). Secondly, corrupted data temporarily stored and merged with the data retransmission corresponding to the transferred data before. In the scheme DPWNS signal KVIT and packetized data retransmission exchanged between the user equipment and high speed shared channel downlink (SU-STNLS, HS-DSCH) access control environment (UDS, MAC) node Century Scheme DPWNS introduces N-channel scheme GASP OI the, which forms the N logical channels and transmits multiple data packets before receiving the signal KVIT. In the case of schemes ASP the Reis, signal KVIT for the previous packetized data must be received before sending the next packetized data. Therefore, the scheme ASPP the Reis disadvantageous that the user equipment or the node b shall from time to time be expected signal KVIT even though it can currently transmit packetized data. N-Kalina scheme GASP the Reis can increase the efficiency of the channels through continuous transmission of multiple data packets before receiving the signal KVIT for the previous packetized data. That is, if N logical channels are established between the user equipment and node B, and N logical channels can be identified by a certain time or channel number user equipment, receiving packetized data may identify a logical channel through which were transmitted packetized data received at a certain time, and to reconfigure the packaged data in the correct order admission or merge the software, the corresponding packetized data.

Scheme GASP can be classified in the scheme of merger with tracking (CCS, CC)diagram of the full incremental redundancy (PI is, FIR) and the scheme for partial incremental redundancy (CHII, PIR). In the scheme of CCA the same all packetized data transmitted in the initial transmission are transmitted even when re-transmission. The receiver combines the retransmitted packetized data originally transmitted packetized data to improve the reliability of coded bits are fed into the decoder, thereby obtaining improved performance of the entire system. When two of the same data packet are combined, is the effect of coding, similar to the effect of iterative coding, so is the improved performance on average by approximately 3 dB. In the scheme of FDI, as relayed packetized data, consisting only of redundancy bits generated by the encoder channels, the coding efficiency of the decoder in the receiver increases. That is, the decoder during decoding uses the new redundancy bits, and the originally transmitted information, leading to an increase in coding efficiency and contributing thereby to the improvement of its characteristics. Scheme CHII, unlike the FDI scheme, transmits packetized data comprising information bits and the new redundancy bits in combination. During decoding of the information bits are combined with the original transmitted information bits and, thus providing an effect similar to the effect of the CCA scheme. In addition, since the scheme CHII for decoding uses bits of redundancy, in fact, this is similar to the diagram of FDI. Because the scheme CHII relatively higher scheme of FDI in terms of encoding speed, it has approximately intermediate the improvement of the characteristics between the FDI scheme and the scheme is CCA. However, because the scheme GASP takes into account the complexity of the system type of the buffer size of the receiver and signal transmission, as well as improved performance, a suitable scheme to choose is not easy.

Using the AMC scheme and the scheme GASP significantly improves the performance of the system as a whole. However, even using the AMC scheme and the scheme GASP basically can not solve the problem lack of radio resources in wireless communication. In order to maximize bandwidth, subscribers, and to allow high-speed data transmission necessary for multimedia service, you need a new multiple access scheme, having superior spectrum efficiency for high-speed, high-quality transmission of packetized data. There is also a need in the way of adaptive data transmission/reception in accordance with the state of the channel or channels in the new high-speed, vysokokachestvenn the th multiple access scheme, having superior spectrum efficiency.

A detailed description of the preferred option implementation

Now will be described in detail the preferred implementation of the present invention with reference to the drawings. In the following description, a detailed description is included here known functions and configurations are omitted for brevity.

The present invention provides a multiple access scheme for efficient use of frequency-time resources for high-speed, high-quality wireless multimedia services, planned system of mobile communication of the next generation.

To ensure high-speed, high-quality wireless multimedia services, planned system of mobile communication, the next generation, the necessary resources shirokopolosnogo the spectrum. However, the use of broadband spectrum resources increases the effect of fading in radio communication lines due to multipath propagation and causes frequency-selective fading even within the bandwidth. Therefore, for high-speed wireless multimedia service scheme orthogonal multiplexing frequency division (OMCR), which is resistant to frequency selective fading, has a higher gain, in comparison with the scheme multiple access code division (mdcr).

In General it is known that the scheme OMCR has high spectrum efficiency, since the spectra between carriers or channels of subcarriers overlap each other, at the same time maintaining mutual orthogonality. In the scheme OMCR modulation is performed by using the inverse fast Fourier transform (OBPF), and demodulation is performed using fast Fourier transform (FFT). As the multiple access scheme based on the scheme OMCR, provided orthogonal multiple access frequency division (ADCR), in which some or all of the subcarriers are assigned to a specific mobile station. Scheme ADCR needs no sequences distribution distribution and can dynamically change the set of subcarriers assigned to a particular mobile station, in accordance with the characteristics of the fading radio links. Dynamic changes in the set of subcarriers assigned to a particular mobile station, called the scheme "dynamic resource allocation". Diagram of frequency hopping (HRC, FH) is an example of a schema for dynamic allocation of resources.

However, the multiple access scheme that requires expanding sequence, classified in the schema extensions in the time domain and schema extensions in the frequency domain. Schema extensions in the time domain extends the signals of the mobile station or user equipment in a temporary area, and then displays the extended signal in subcarriers. Scheme of expansion in the frequency domain further demultiplexes the signals of the users in the time domain, displays demultiplexing signals to subcarriers and identifies the signals of the users, using the orthogonal sequence in the frequency domain.

The multiple access scheme proposed in the present invention, characterized in that it is based on the scheme OMCR, and additionally, it has the characteristic of mdcr and relatively stable frequency-selective fading in the frequency due to the scheme HRS. Here recently proposed multiple access scheme called scheme "WITH THE H-MDCR/FDM (frequency hopping - orthogonal multiple access with frequency separation/multiplexing code division)".

Below will now be described scheme HRC-MDCR/MCR proposed in the present invention.

Scheme HRC-MDCR/MCR effectively assigns a frequency-time resources for multiple mobile stations. Frequency-time resources assigned to each of the mobile stations, defined bandwidth and time. Bandwidth is assigned in accordance with the type of service required by each mobile station. For example, a wide bandwidth is assigned to the mobile station requiring service, which needs a time-frequency resource type high-speed transmission of packetized data. While narrow band assigned to the mobile station requiring service, which requires a small time-frequency resource, the type of voice service. This means that for each mobile station can be assigned to different frequency-time resources.

Figure 1 is a diagram illustrating a method for assigning a frequency-time resources based on the schema of the HRC-HDRO/MCR in accordance with the embodiment of the present invention. Consider figure 1, where the scheme of the HRC-HDRO/MCR as described above, to maximize the improvement of ha is acteristic by combining the characteristics of the scheme OMCR, schema mdcr and diagrams of the human rights Council and divides the bandwidth into many areas of subcarriers or areas of subcastes (or ranges). As is illustrated in Fig. 1, the region having the frequency region ΔfCVAconsisting of a specified number of areas subcostal using the same duration ΔtCVAas the range of symbols OMCR, defined as "frequency-time cell (CVA, TFC)". CWA consists of a specified number of areas subcastes. The number of areas of subcostal comprising CVE, can a variable be set in accordance with the situation in the system. Next, the frequency domain occupied CVA, is defined as "the frequency domain CVA", and the time interval occupied CVA, is defined as "the time interval CVA". That is, a single rectangle illustrated in Fig. 1 represent the cell CWA. The present invention processes the data corresponding to the areas of subcostal assigned CVE scheme mdcr, and processes of subcarriers corresponding to areas of subcostal scheme OMCR. The processing circuit mdcr is a process of expanding data codes through the allocation of bandwidth to individual channels, pre unambiguously assigned subcarriers, and the scrambling extended data specified scrambling code.

As illustrated in figure 1, the plural the creation of cells CVA constitute one cell frames (UC), and YAK has a duration of ΔtYAKcorresponding to the specified value multiple of the duration ΔtCVAcell CVA using bandwidth ΔfYAKcorresponding to the specified value multiple of the width of the band ΔfCVAcell CWA. For convenience of explanation, here it is assumed that the YAK has a width corresponding to 16 times the bandwidth ΔfCVAcell CVA (ΔfAku=16ΔfCVA), and the duration of ΔtYAKcell YAK has a duration corresponding to 8 times the duration ΔtCVAcell CVA (ΔtYAK=8ΔtCVA). The frequency region occupied by the YAK, is defined as the frequency domain YAK", and the temporary area occupied by the YAK will be defined as "a temporary area YAK". The reason for determining the YAK so is to prevent interference caused by frequent communication from the measurement result to the radio transmissions of the type of information about the quality of channels (KIC), when used as a scheme of adaptive modulation and coding (AMC) in the communication system, applying a scheme of the HRC-HDRO/MCR (communication system HRC-MDCR/MCR). The entire frequency range of the communication system HRC-MDCR/MCR is divided into a given number of frequency bands of the YAK. For convenience of explanation here, it is assumed that the entire frequency range of the communication system HRC-MDCR/MCR) is EN by M frequency bands of the YAK. Split M cells YAK, from the first to the (M-1)-th cell of the YAK used to transmit packetized data, and M-th YAK is used for data management or information management. The number of cells YAK used to transmit packetized data, and the number of cells YAK used to transmit control information, you can set a variable manner in accordance with the state of the system. The number of cells YAK for transmitting packetized data and the number of cells YAK for transmission of control information is determined with reference to the issue, namely, that when the number of cells YAK used to transmit control information increases, the number of cells YAK used to transmit packetized data is reduced, thus causing a decrease in data transfer speed. Here, for convenience of explanation, the YAK used to transmit packetized data is defined as "YAK data, and YAK, used to transmit control information that is defined as "YAK"control.

In figure 1, one YAK included two different subchannel, i.e., the sub-channel and sub-channel Century. the Term "sub-channel" refers to the channel in which with the passage of time a specified number of cells YAK abruptly rebuild frequency prior to transmission in accordance with a specified scheme abruptly the frequency. The number of cells CVA forming the sub-channel, and the pattern of frequency hopping can be set variable in accordance with the state of the system. For convenience of explanation here, it is assumed that one sub-channel is 8 cells CWA.

When the AMC scheme is used in the communication system HRC-MDCR/MCR, the mobile station performs an operation of measuring the radio link in the given period and reports the measurement result to the base station. The state of the radio link can be identified, for example, through information about the quality of channels (KIC). The base station adjusts the modulation scheme and the coding scheme on the basis of information about the state of the radio link, reported from the mobile station, and informs the mobile station about adjusted the modulation scheme and the coding scheme. Then the mobile station transmits signals in accordance with the adjusted modulation scheme and a coding scheme formed the base station. In the present invention, since the communication of information about the state of the radio link is made on the basis of the YAK, the load transmitting signals, which may occur due to the use of the AMC scheme, reduced to a minimum, and interference due to transmission of signals is also reduced to a minimum. That is, the management information is transmitted via the YAK to transmit information pack is Alenia. The sub-channel must be assigned to a specific mobile station, taking into account the quality of service (QoS) of the mobile station along with all the mobile stations in operation.

Figure 2 presents a block diagram schematically illustrating a procedure for assigning the subchannels based on the channel quality in accordance with the embodiment of the present invention. Before to describe figure 2, it should be noted that although the assignment of subchannels in accordance with the channel quality is performed on all mobile stations that are in communication with the base station, figure 2, for convenience of explanation it is assumed that the procedure is performed between the base station and a particular mobile station.

With regard to figure 2, there on the stage 211, the base station analyzes the information about the quality of channels transmitted on the feedback channel from the mobile station, sequentially arranges the (M-1) cells YAK communications systems HRC-MDCR/MD from UC with the best channel quality, to YAK with the worst channel quality, and then proceeds to step 213. Here, the mobile station transmits the channel feedback information about the channel quality cells YAK to the base station, and information about the quality of channels may include signal-to-noise ratio (SNR). In addition, the m-th quality of the channel is defined as "rm", and rmis the quality of the channels of the m-th YAK. At step 211, it is assumed that the quality of r1channels of the first YAK is the best, and the quality of rM-1channels (M-1)-th YAK - the worst (r1≥ r2≥ ... ≥ rM-1).

After ordering the cells YAK in accordance with the channel quality at the step 213, the base station selects cells YAK for transmitting packetized data and the sub-channels based on the channel quality in accordance with the number of packetized data transmission, and then proceeds to step 215. Cell YAK for transmitting packetized data sequentially selected from a YAK that has the best channel quality. For example, when there is the sub-channel available to YAK with the best channel quality is selected YAK. When there is no subchannel available for YAK that has the best quality channels, if there are sub-channel available to YAK with the second best channel quality is selected YAK, having the second best channel quality. The process of selecting cells YAK in accordance with the number of packetized data transmission, and to select subchannels will be described below.

At step 215, the base station transmits packetized data corresponding to the selected subchannel YAK, transmits the management information related to the transfer of packetized data over the cell YAK for transfer details is rmacie management and then proceeds to step 217. At step 217, the base station receives information about the quality of channels transmitted over the feedback channel from the mobile station analyzes the received information about the quality of channels, and then returns to step 211.

Figure 3 presents a detailed block diagram of the program, illustrating the assignment of subchannels figure 2. Before giving the description of figure 3, it should be noted that although the assignment of subchannels in accordance with the channel quality is performed on all mobile stations that are in communication with the base station in figure 3 for convenience of explanation it is assumed that the procedure is performed between the base station and a particular mobile station.

Consider figure 3, where in step 311, the base station analyzes the information about the quality of channels transmitted on the feedback channel from the mobile station, sequentially arranges the (M-1) cells YAK communications systems HRC-MDCR/MD from UC with the best channel quality, to YAK with the worst channel quality, and then proceeds to step 313. At step 311, it is assumed that the quality of the channels r1the first YAK is the best, and the quality of the channels rM-1(M-1)-th YAK - the worst, (r1≥ r2≥ ... ≥ rM-1). Step 211, described in figure 2, is essentially identical to step 311. At step 313 the base stations which sets the parameter j, specifies the number of cells YAK in the communication system HRC-HDRO/MCR, '1' (j=1), sets the flag indicating transferred to whether the packetized data transmission through one YAK or two or more cells YAK, '0' (Flag=0) and then proceeds to step 315. Here it is assumed that the number of cells YAK in the communication system HRC-MDCR/MCR equal to M-1, and the parameter j is set so as to determine whether there is an available sub-channel in the corresponding YAK. The flag is set to '0'when the packetized data transmission is transmitted through one of the YAK, and the flag is set to '1'when the packetized data transmission is transmitted through two or more cells YAK, that is, when the packetized data transmission are separated prior to transmission. The flag is set to indicate whether the packetized data transmission to be transmitted through one YAK or distributed prior to transmission on multiple cells UC. The expression "the number of cells UC" represents the number of cells YAK, existing in the same time interval YAK ΔtYAK.

The base station at step 315 determines whether the value of the parameter j values M-1 (j > M-1). If it is determined that the value of j exceeds M-1, the base station proceeds to step 317. If the value of j exceeds M-1, this means that the available YAK no. At step 317, the base station determines that the transfer of packeteer the bathrooms of data is impossible, since there is no available YAK, and then proceeds to step 319. At step 319, the base station monitors the channel quality for each of the YAK, and then returns to step 311. Here, the expression "controlling the quality of channels for each YAK" means analyzing information about the quality of channels received from the mobile station, and controlling the quality of channels corresponding to the information about the quality of channels. However, if at step 315 it is determined that the value of the parameter j does not exceed M-1 (j ≤ M-1), the base station proceeds to step 321. The base station at step 321 determines whether the j-th YAK be used to transmit packetized data, i.e. whether the j-th YAK. If it is determined that the j-th YAK is not available, the base station proceeds to step 323. At step 323, the base station increases the value of the parameter j by 1 (j=j+1) and then returns to step 315. Here, the reason for increasing values of the parameter j 1 is to determine whether the (j+1)-th YAK available, because j-th YAK is not available.

If at step 321 determines that the j-th YAK is available, the base station proceeds to step 325. At step 325, the base station determines whether the flag value to 0. If it is determined that the flag value is set to 0, the base station proceeds to step 327. Here, the expression "flag value set to 0" means that paketi the consistent data transmission can be transmitted through one YAK, as explained above. At step 327, the base station determines whether there is enough available subchannels for transmitting packetized data available in the j-th YAK. Here the expression "sufficiently available subchannels for transmitting packetized data available in the j-th YAK" means that the j-th YAK there are at least three available subchannel, as, for example, to send packetized data requires three subchannel. If it is determined that the j-th YAK has sufficient available subchannels for transmission of packetized data, the base station proceeds to step 329. At step 329, the base station assigns the packaged data to packetized data to be transmitted via the available subchannels in the j-th YAK and then proceeds to step 319.

If at step 327 determined that for the transmission of packetized data in the j-th YAK sufficient number of available subchannels does not exist, the base station proceeds to step 331. Here the expression "for the transmission of packetized data in the j-th YAK sufficient number of available subchannels does not exist" means that the j-th YAK there are fewer than three available subchannel as to transmit the packaged data is required, for example, three subchannel. At step 331, the base station sets the flag value to 1 (Flag=1), because there are not enough accessible the x subchannels for transmitting packetized data in the j-th YAK, and then proceeds to step 333. Here, the value of flag is set to 1, since the transfer of packetized data only through j-th YAK impossible, that is, because the transmission of packetized data through only one YAK is impossible, because a sufficient number of available subchannels for transmitting packetized data in the j-th YAK does not exist.

At step 333, the base station assigns the packaged data so that only the portion of the packetized data was transferred through the available subchannels in the j-th YAK, and then proceeds to step 335. At step 335, the base station increases the value of the parameter j by 1 (j=j+1) and then returns to step 315. Here, the reason for increasing values of the parameter j 1 is to transmit packetized data through the (j+1)-th YAK, since the transfer of packetized data only through j-th YAK impossible.

If at step 325 it is determined that the flag value is not set to 0, that is, if the flag value is set to 1, the base station proceeds to step 337. At step 337, the base station determines whether there is a sufficient number of available subchannels for transmitting packetized data in the j-th YAK. If at step 337 is determined that a sufficient number of available subchannels for transmitting packetized data in the j-th YAK does not exist, the base station proceeds to etapu. However, if at step 337 is determined that a sufficient number of available subchannels for transmitting packetized data in the j-th YAK exists, the base station proceeds to step 339. At step 339, the base station assigns the packaged data so that the remaining portion of the packetized data was transferred through the available subchannels in the j-th YAK, and then proceeds to step 319.

Figure 4 is a block diagram illustrating the internal structure of the base station device according to the embodiment of the present invention. With regard to figure 4, the base station device consists of a module 411 ordering frame cell, module 413 assignment of subchannels, the transmitter 415 channels, receiver 417 information about the quality of channels and devices 419 determine the size of the packages. Information about the quality of channels transmitted on the feedback channel from the mobile station, served in the receiver 417 information about the quality of channels. The receiver 417 information about the quality of channels determines the quality of channels for all cells YAK data, i.e., for (M-1) cells YAK data communication systems HRC-MDCR/MCR using the accepted information about the quality of channels, and outputs the detected result to the module 411 ordering of frame cells. Module 411 ordering of cell frames sequentially arranges the (M-1) cells YAK data from UC with the best-the quality of the channels, using the information on the channel quality received from the receiver 417 information about the quality of channels, and outputs the result of ordering in the module 413 assignment of subchannels. Module 413 assignment assigns subchannels subchannels for transmitting packetized data in accordance with the ordering on the basis of channel quality received from the module 411 ordering of frame cells. The assignment operation cells YAK and subchannels for transmitting packetized data module 413 assignment of subchannels described with reference 2 and 3.

After the module 413 assignment of subchannels completes the assignment of cells YAK and subchannels for transmitting packetized data, the transmitter 415 channel processes the packetized data based on the capabilities of the channels in accordance with the assignment of subchannels and transmits the packetized data to the assigned subchannels. Further, the transmitter 415 channels processes taking into account the capacity of the channels the management information related to the transfer of packetized data and transmits the management information on the subchannel assigned for the transmission of control information. Here the sub-channel, which are transmitted packetized data, defined as "data channel", and the sub-channel that carries control information, defined as the "control channel". The data channel is transmitted through Janneh, and the control channel is transmitted through the YAK control. Module 413 assignment assigns subchannels subchannels intended for packetized data transmission, in accordance with the size of the packages provided by the device 419 determining the dimensions of packages. After receiving packetized data transmission device 419 determine the size of the packet determines the size of the packaged data and reports module 413 assignment of subchannels defined packet size, and then the module 413 assignment assigns subchannels subchannels in accordance with the size of the packaged data.

Figure 5 shows the block diagram of a program illustrating the procedure of operation of the mobile station in accordance with the embodiment of the present invention. With regard to figure 5, there mobile station receives signals corresponding to the M cells YAK, from the base station during the time interval YAK. At step 511 the mobile station measures the channel quality for accept (M-1) cells YAK data and then proceeds to step 513. Next, at step 515 the mobile station demodulates the control channels included in YAK control of the number M of cells YAK and then proceeds to step 517. At step 513 the mobile station transmits the channel feedback information about the quality of channels (M-1) cells YAK data to the base station, and then returns the I to steps 511 and 515.

At step 517 the mobile station determines whether to demodulate the data channel as a result of demodulation on the control channel. If it is determined that there is no need to demodulate the data channel, the mobile station ends the procedure. However, if at step 517 determines that the data channel is necessary to demodulate, the mobile station proceeds to step 519. At step 519 the mobile station demodulates the data channel in cells YAK data, and ends the procedure.

Figure 6 presents a block diagram illustrating the device structure of the mobile station in accordance with the embodiment of the present invention. Consider Fig.6, in which the mobile station device consists of a meter 611 channel quality of the cell frames, demodulator 613 channel control demodulator 615 data channels and transmitter 617 information about the quality of channels. The mobile station receives signals corresponding to the M cells YAK, from the base station during the time interval YAK. Take M cells YAK served on the meter 611 channel quality of the cell frames, the demodulator 613 of the control channels and the demodulator 615 data channels. Meter 611 channel quality frame cell measures the channel quality for accept (M-1) cells YAK data and outputs the result to the transmitter 617 information about the quality of channels. The transmitter 617 in the information about the quality of channels defines information about the quality of channels for each of the (M-1) cells YAK data based on the channel quality for the (M-1) cells YAK data received from the meter 611 channel quality of the cell frames, and transmits the channel feedback some information about the channel quality to the base station.

The demodulator 613 control channels demodulates the control channels in YAK control of the numbers taken M cells UC. As a result of demodulation on the control channels, if it is determined that there is a data channel that is defined for the mobile station, a demodulator 613 control channels tells the demodulator 615 data channels, the data channel must be demodulated. Then the demodulator 615 data channels demodulates a corresponding data channel of the M cells YAK running demodulator 613 control channels and outputs the demodulated signal as the received packetized data.
