The technical field

The present invention generally relates to a broadband wireless communication system and in particular to a device and method for reducing informational messages about resource allocation in broadband wireless systems.

The level of technology

The communication system of the future generation system called 4th generation (4G), are being actively pursued to provide users with services with different quality of service (QoS) at the transmission rates of l00 Mbps or higher. Especially actively researched area relating to the provision of high-speed services by ensuring mobility and QoS guaranteed communication system with wireless broadband access (BWA), such as a wireless local area network (WLAN) and wireless Metropolitan area network (WMAN). A large communication system is a system of Institute of engineers on electrical and electronics (IEEE) 802.16e.

Main standards developed by the working group for IEEE 802.16, are IEEE 802.16d and IEEE 802.16e, which are classified into a system with a single carrier, the multiplexing orthogonal frequency division multiplexing (OFDM), and systems with orthogonal multiple access frequency division multiple access (OFDMA). The IEEE 802.16d/e for OFDMA defines the structure of frames downlink(DownLink, DL) and uplink communication (Uplink, UL) with time and frequency resources and the allocation of resources based on the state of radio frames for efficient transmission of digital bit information to the receiver.

In Fig. 1 shows the frame structure in a conventional OFDMA communication system.

In Fig. 1 OFDMA frame contains a frame DL 110 and the frame 120 UL.

The frame 110 DL consists of a preamble 111, header 113 management frame (FCH), a DL-MAP 115, UL-MAP 117 and 119 packages data for DL.

Preamble 111 provides information by which a mobile station (MS) reaches initial synchronization and performs the search of the cell. FCH 113 specifies the encoding scheme of the DL-MAP 115 and UL-MAP 117. DL-MAP 115 provides information about the allocation of resources for each MS, and UL-MAP 117 provides information about the allocation of resources to the regions 121 of the control frame 120 UL and packages 123 UL data that must be transferred from stations MS. Packages 119 DL data transfer user data from the base station (BS) to the stations MS.

The frame 120 UL contains regions 121 and control packets 123 UL data. Region 121 management deliver the management information required for communication from stations MS to the BS, and packages 123 UL data transfer user data from stations MS to the BS.

Region 121 controls contain the channel 151 ranking, channel 153 quality information channel (CQI)channel 155 confirm the confirm (ACK) and channel 157 sensing.

MS may transmit data to the BS without resource allocation from the BS according to the channel 151 ranking. Channel 151 ranking is used for primary network logon requests divert calls or request the allocation of resources. Channel 153 CQI notifies the BS about link-state DL on MS. Channel 155 ACK BS indicates that you have successfully received by the MS DL data packet. Channel 157 sensing is the area from which the BS receives channel information of the MS.

In the above described frame structure for OFDMA information MAP and data packets compete for resources, because the field MAP with informative messages about resource allocation and data packets of the user configured in the same frame. Information MAP and packages user are dependent on the compromise from the point of view of resources. This means that as the amount of information of the MAP increases, the amount of resources available for packages of the user is reduced. Although the frame structure is dynamically changed, such a case is rare in the real implementation of the system. In particular, the area 121 of the control frame 120 UL tend to have the same configuration in each frame. The transmission of the same information messages about resource allocation in each frame leads to the reduction of resources allocated to package the data, thereby reducing the overall data rate of the system.

The best mode of carrying out the invention

Preferred embodiments of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described what are stated, so how can they voiceroute the invention with unnecessary details.

The present invention discloses a device and method for increasing data transmission speed of the system by reducing the overhead of informational messages about resource allocation in a broadband wireless communication system. The following description will be made in the context of OFDMA systems through an example.

In Fig. 2 shows a block diagram of the transmitter of the BS in the OFDMA communication system in accordance with the present invention.

With reference to Fig. 2, the transmitter includes a scheduler 201, generator 203 MAP, channel encoder 205, the modulator 207, block 209 purpose, the modulator 211 OFDM, digital to analog Converter (DAC) 213 and transmitter 215 radio frequency (RF) range.

The scheduler 201 generates scheduling information for allocating resources in the field of the DL data packets, data packets UL and information UL (hereafter "information planning the allocation of resources"). Management UL contain the channel ranking, channel CQI, the ACK channel and a sounding channel. The CQI channel is equivalent to a fast channel feedback. In particular, the scheduler 201 determines whether to create information on the allocation of resources to areas of management UL (hereafter "information on the allocation of resources to areas of management UL") in accordance with h is a worthwhile invention. Information on the allocation of resources to areas of management UL can touch all areas of management UL or part of the areas of management UL. When it comes time to create information on the allocation of resources to areas of management UL or when information on the allocation of resources to areas of management UL is changed, the scheduler 201 manages the information on the allocation of resources to areas of management UL, which should be created. Especially in the latter case, the scheduler 201 manages the information on the allocation of resources to areas of management UL, which must be created in a predetermined number of consecutive frames.

The generator 203 MAP creates a message MAP, i.e. the information about the distribution of resources, based on information planning, resource allocation, adopted from the scheduler 201. In particular, the generator 203 MAP creates a message MAP in accordance with whether the scheduler 201 information on the allocation of resources to areas of management UL, that is, if the information on the allocation of resources to areas of management UL created, the generator 203 MAP creates a message MAP containing information about the allocation of resources to areas of management UL. In this case, the generator 203 MAP in the message MAP contains information about the actual time associated with information about the allocation of resources to areas of management UL. On the other side is s, if the information on the allocation of resources to areas of management UL is not created, the generator 203 MAP creates a message MAP no information about the allocation of resources to areas of management UL.

Channel encoder 205 encodes the information about the allocation of resources taken from the generator 203 MAP, with a predetermined encoding speed. The modulator 207 modulates the coded data received from the channel encoder 205, the characters in a pre-defined modulation scheme (such as quadrature phase-shift keying (QPSK)).

Block 209 assignment assigns symbols in accordance with the frame structure, that is, subcarriers of the frame. The modulator 211 OFDM converts the assigned symbol, i.e. of the signal with frequency encoding in the signal with time coding, by using the inverse fast Fourier transform (IFFT).

The DAC 213 converts the signal with time coding in analog signal and transmitter 215 radio band performs up-conversion of the analog signal at the carrier frequency and transmits the signal at the carrier frequency through the antenna.

In Fig. 3 shows a block diagram of an MS receiver in the OFDMA communication system in accordance with the present invention.

With reference to Fig. 3, the receiver includes a receiver 301 RF range, analog-to-digital Converter (ADC) 303, a demodulator 305 OFDM, extractor 307 MAP demodulator 309, channel is ecoder 311 and the interpreter 313 MAP.

The receiver 301 RF range converts passed through the antenna, the RF signal down in frequency to the signal in the band of modulating frequencies and the ADC 303 converts the baseband signal into a digital signal.

The demodulator 305 OFDM transforms the signal from time coding, taken from the ADC 303, a signal with frequency coding using fast Fourier transforms (FFT). The extractor 307 MAP extracts the signal MAP of the signal with frequency encoding.

The demodulator 309 demodulates the signal MAP in a predetermined demodulation scheme and a channel decoder 311 decodes the demodulated data MAP with a predetermined encoding speed.

The interpreter 313 MAP interprets information MAP adopted from the channel decoder 311, and updates the information about the resources provided by MS. In particular, the MAP interpreter 313 determines whether information of the MAP information on the allocation of resources to areas of management UL, and accordingly updates the stored information on the allocation of resources to areas of management UL in accordance with the present invention. When the presence information of the MAP information on the allocation of resources to areas of management UL interpreter 313 MAP updates the stored information on the allocation of resources to areas of the UL control information on the allocation of resources to areas of management UL. In the absence of the information MAP information the purpose of allocating resources to the areas of management UL interpreter 313 MAP retains the stored information on the allocation of resources to areas of management UL. In the case when the message MAP contains information about the actual time, if new information on the allocation of resources to areas of management UL has not been received before the expiration of the valid duration, specified information about the actual time, the interpreter 313 MAP deletes the stored information on the allocation of resources to areas of management UL. Here management UL contain the channel ranking, channel CQI, the ACK channel and a sounding channel. The CQI channel is equivalent to a fast channel feedback.

Although not shown, the transmitter control signal transmits to the BS alarm UL (for example, ranking, CQI, ACK etc), based on the information on the resources allocated to the areas of management UL.

In Fig. 4 shows a block diagram explaining the operation of a BS in the creation of informational messages about resource allocation in the OFDMA communication system according to a variant example of implementation of the present invention.

With reference to Fig. 4, the generator 203 MAP at step 401 determines whether there has come the time to create the message MAP. If the creation time of the message MAP came generator 203 MAP at step 403 checks the schedule resource allocation for DL and UL.

At step 405 generator 203 MAP determines any changes to the information on the allocation of resources to areas of management UL, comparing the set of information is about the allocation of resources to areas of management UL, established in the schedule of allocation of resources, with the last reported information about the allocation of resources to areas of management UL. As stated earlier, management UL contain the channel ranking, channel CQI, the ACK channel and a sounding channel and the CQI channel is equivalent to a fast channel feedback.

If the information on the allocation of resources to areas of management UL has been changed, the generator 203 MAP at step 407 sets the variable "m" to 0. The variable m indicates the number of frames without information about the allocation of resources to the areas of management, passed after the change of information on the allocation of resources to areas of management UL.

At step 409 generator 203 MAP creates a message MAP with the changed information on the allocation of resources to areas of management UL. Information on the allocation of resources to areas of management UL may relate to all or part of the areas of management UL.

On the other hand, if the information on the allocation of resources to areas of management UL has not been changed, the generator 203 MAP at step 411 determines whether the time has come to create information on the allocation of resources to areas of management UL. Specifically, the generator 203 MAP counts the number of consecutive transmission MAP no information about the allocation of resources to areas of management UL after the transfer MAP with information about the allocation of resources to areas of management UL and srawniwa the t result of the calculation with a predetermined period to generate information on the allocation of resources to areas of management UL. The period is variable, depending on system configuration.

If at step 411 the time has come to create information on the allocation of resources to areas of management UL, generator 203 MAP at step 409 creates a message MAP with information about the allocation of resources to areas of management UL tested in step 403.

If at step 411 it is the creation time information on the allocation of resources to areas of management UL, generator 203 MAP at step 413 increments m by 1. If after the increase m the creation time information on the allocation of resources to areas of management UL has not come, the generator 203 MAP at step 415 compares m with a variable "N". N specifies the number of consecutive frames with information about the allocation of resources to areas of management UL to ensure receiving the modified information on the allocation of resources to areas of management UL, that is, the modified information on the allocation of resources to areas of management UL is transmitted in N consecutive frames, as counted from the moment when the information on the allocation of resources to areas of management UL has been changed. N depends on the system configuration.

If m is less than N, the generator 203 MAP at step 409 creates a message MAP with information about the allocation of resources to areas of management UL.

If m is greater than or equal to N, the generator 203 MAP at step 417 creates a message MAP no information about the allocation of resources to areas of the UE is Alenia UL.

In Fig. 5 shows a block diagram of a sequence of operations on MS for detection of informational messages about resource allocation in the OFDMA communication system according to a variant example of implementation of the present invention.

With reference to Fig. 5, the interpreter 313 MAP at step 501 controls the reception of the message MAP.

After receiving the message, the MAP interpreter 313 MAP at step 503 determines whether a message contains MAP information on the allocation of resources to areas of management UL. Management UL contain the channel ranking, channel CQI, the ACK channel and the channel sensing and channel CQI is equivalent to fast channel feedback.

If there is information on the allocation of resources to areas of management UL interpreter 313 MAP at step 505 updates the information on the allocation of resources to areas of management UL on the accepted information about the allocation of resources to areas of management UL.

In the absence of information on the allocation of resources to areas of management UL interpreter 313 MAP at step 507 stores the stored information on the allocation of resources to areas of management UL.

The interpreter 313 MAP at step 509 checks the information fields of the data packets and then ends the algorithm of the present invention.

In Fig. 6 shows a block diagram of a sequence of operations on the BS to generate informational messages about the location is edelenyi resources in the OFDMA communication system in accordance with another variant example of implementation of the present invention.

With reference to Fig. 6, the generator 203 MAP at step 601 determines whether there has come the time to create the message MAP. If this time has come, the generator 203 MAP at step 603 checks the schedule resource allocation for DL and UL.

At step 605 generator 203 MAP determines whether the changed information on the allocation of resources to areas of management UL, comparing information on the allocation of resources to areas of management UL, established in the schedule of allocation of resources, with the latest reported information on the allocation of resources to areas of management UL. As stated earlier, management UL contain the channel ranking, channel CQI, the ACK channel and the channel sensing and channel CQI is equivalent to fast channel feedback.

If the information on the allocation of resources to areas of management UL has been changed, the generator 203 MAP at step 607 generates information about the actual time for information about allocating resources to the areas of management UL. Because the transmitted information on the allocation of resources to areas of management UL is not valid after the time period has expired, in the case of periodic transmission of information on the allocation of resources to areas of management UL generator 203 MAP creates information about the actual time to notify the MS of the period.

At step 609 generator 203 MAP creates a message MAP with the modified INF is armacia on the allocation of resources to areas of the UL control information and the actual time. Information on the allocation of resources to areas of UL control information may include information about some or all areas of management UL.

On the other hand, if the information on the allocation of resources to areas of management UL at step 605 was not changed, the generator 203 MAP at step 611 determines whether there has come the time to create the information on the allocation of resources to areas of management UL. Specifically, the generator 203 MAP counts the number of consecutive transmission MAP no information about the allocation of resources to areas of management UL after the transfer MAP with information about the allocation of resources to areas of management UL and compares the result of the calculation period. The period is variable, depending on system configuration.

If the creation time information on the allocation of resources to areas of management UL at step 611 has not come, the generator 203 MAP at step 613 creates a message MAP no information about the allocation of resources to areas of management UL.

In Fig. 7 shows a block diagram of a sequence of operations on MS for detection of informational messages about resource allocation in the OFDMA communication system in accordance with another variant example of implementation of the present invention.

With reference to Fig. 7, the interpreter 313 MAP at step 701 controls the reception of the message MAP.

After receiving the message, the MAP interpreter 313 MAP at step 703 determines liliopsida MAP information on the allocation of resources to areas of management UL. Management UL contain the channel ranking, channel CQI, the ACK channel and the channel sensing and channel CQI is equivalent to fast channel feedback.

If there is information on the allocation of resources to areas of management UL interpreter 313 MAP at step 705 updates the stored information on the allocation of resources to areas of management UL on the accepted information about the allocation of resources to areas of management UL.

In the absence of information on the allocation of resources to areas of management UL, the MAP interpreter 313 at step 707 determines whether the stored previous information on the allocation of resources to areas of management UL.

If the previous information on the allocation of resources to areas of management UL was saved, the interpreter 313 MAP at step 709 checks the actual length of the stored information on the allocation of resources to areas of management UL.

If the information on the allocation of resources to areas of management UL is still valid, the interpreter 313 MAP at step 711 stores without changing the stored information on the allocation of resources to areas of management UL.

On the contrary, if at the step 709 is determined that the information on the allocation of resources to areas of management UL is not valid, the interpreter 313 MAP at step 713 deletes the stored information on the allocation of resources to areas of management UL. Because information from the attachment resource areas management UL, whose valid duration has expired, inaccurate, use of the area specified in the information about the allocation of resources to areas of management UL, terminated by removing the information on the allocation of resources to areas of management UL. In addition to the removal, MS can be selected to indicate whether valid information on the allocation of resources to areas of management UL, or MS can always check the actual length of the information on the allocation of resources to areas of management UL.

The interpreter 313 MAP at step 715 detects information of the packet data areas.

In the above-described embodiments, the implementation of the present invention, the information on the allocation of resources to areas of management UL periodically created and entered in the message MAP. Here is information on the allocation of resources to areas of management UL can describe the distribution of resources to all areas of control UL or specific management, such as area ranking.

Offered a third alternative implementation of the present invention, in which the BS when creating an information MAP sets the indicator in the actual time for each area of management UL. For example, the connection identifier (CID)that is contained in the information element UL-MAP (UL-MAP_IE), can be used as an indicator really is time information about the distribution, contained in the UL-MAP_IE. For item UL-MAP_IE, which provides initial information about the ranking, "0000", made BS in CID contained in the UL-MAP_IE, may indicate that the initial information area ranking is only valid until until transferred to a new initial information about the area ranking. Installation of "ffff"made BS in CID, may indicate that the initial information area ranking is valid only in the frame that carries a UL-MAP_IE, that is, the CID for the UL-MAP_IE can be used to specify the actual length used in the second embodiment of the present invention, that is, if the CID is equal to "0000", the actual length is stored until then, until there is a frame carrying a new initial information about the area ranking. If CID is equal to "ffff", the actual duration is limited to one frame.

Can be considered the fourth variant of implementation of the present invention, in which information on the allocation of resources to areas of management UL is transmitted in the broadcast message. Broadcast the broadcast message is transmitted, but not in every frame. For example, there may be a message descriptor channel uplink communication (Uplink Channel Descriptor, UCD) with additional value length type-Length-Valu, TLV)specified in the table below.

The broadcast message may contain information about the distribution in respect of at least one management UL among the pieces of information listed in the table, that is, the broadcast message may contain information about the distribution for the region ranking (initial region rank region rank transfer, periodic region rank, the width of the strip in the area of ranking and so on), the field of high-speed feedback, in which the CQI is fed back, the field HARQ ACK in which the signal of HARQ response is fed back, and the field sensing probe carrier signal. Information on the distribution in respect of each management area UL element could contain information about the distribution (IE), periodicity, indicating the period for management UL, and the phase distribution that indicates the starting point of the periodicity. The frequency is a parameter d that defines periodicity of 2^d frames, and the phase distribution is expressed in frames per table.

In Fig. 8 shows a block diagram of a sequence of operations on MS for detection of informational messages about resource allocation in a broadband wireless communication system in accordance with the third example in the approaches of the implementation of the present invention.

With reference to Fig. 8, the interpreter 313 MAP at step 801 determines whether the received frame message MAP.

When a message MAP interpreter 313 MAP at step 803 determines whether the reception of the normal MAP, by checking a cyclic redundancy code (CRC) of the message MAP.

If the message MAP is not the norm, interpreter MAP 313 313 at step 805 controls the MS that it has not worked within the frame.

If the message MAP in the normal interpreter 313 MAP at step 807 determines whether the message MAP information on the allocation of resources to areas of management UL.

If there is information on the allocation of resources to areas of management UL interpreter 313 MAP at step 809 updates the current information on the allocation of resources to areas of management UL on the accepted information about the allocation of resources to areas of management UL and at step 811 stores the updated information on the allocation of resources to areas of management UL, that is, the interpreter 313 MAP updates the previously stored information on the allocation of resources to areas of the UL control information on the allocation of resources to areas of management UL.

If no at step 807 information on the allocation of resources to areas of management UL interpreter 313 MAP at step 813 determines whether UCD information on the allocation of resources to areas of management UL.

If there is information on the allocation of resources, the area of the m control UL in UCD interpreter 313 MAP at step 811 stores information about the allocation of resources to areas of management UL, that is, the interpreter 313 MAP updates existing information on the allocation of resources to areas of the UL control information on the allocation of resources to areas of management UL.

After saving the information on the allocation of resources to areas of management UL interpreter 313 MAP at step 815 receives MAP IE for MS.

As apparent from the above description, the present invention successfully increases the data rate of the user by reducing the amount of information messages about the allocation of resources through periodic transmission of information about the distribution of resources associated with a particular area, additional informational messages about the distribution of resources allocated from the BS to the MS in broadcast wireless systems.
