An implementation option 1

The antenna directional diagram

In the embodiment of the present invention different types of channels are transmitted from the base station to the mobile terminal using at least four types of BOTTOM, including: (1) sectoral BOTTOM; (2) multi-leaf BOTTOM; (3) switchable BOTTOM; (4) adaptive towards the BOTTOM.

(1) Pie BOTTOM is aimed BOTTOM, realizes the BOTTOM in a cell or sector served by the base station. In figure 1 the dotted lines show the BOTTOM in the form of a sector of the SEABED in the sector with an angle of 120 degrees.

(2) multi-leaf BOTTOM includes multiple fixed directional BOTTOM, with relatively different fixed directions of orientation. The number of petals is determined so that a number of fixed directional BOTTOM cover is Ali one sector. Figure 2 shows how one sector covered N fixed directional BOTTOM, shown in dashed lines.

(3) Switchable BOTTOM is aimed BOTTOM (may be referred to as a switchable directional BOTTOM)generated by switching one or more fixed directional BOTTOM, included in the multi-leaf BOTTOM, according to the position of the mobile terminal. For example, when a mobile terminal moves from point P to point Q in figure 2, switchable BOTTOM is equivalent to the BOTTOM to 1 at the beginning and then switched in the BOTTOM 3. In addition, for the mobile terminal (for example, at the point R) at approximately the same distance from the BOTTOM 1 and 2, switchable BOTTOM for the mobile terminal can be formed using a aimed BOTTOM, and directed BOTTOM is formed by combining a BOTTOM 1 and 2.

(4) In the adaptive directional BOTTOM of the weighing coefficients may be determined by each antenna for the implementation of the BOTTOM, are calculated in an adaptive way according to the position of the mobile terminal. Switchable BOTTOM, although it has in common with adaptive directional BOTTOM, which consists in the fact that the directional direction varies with the position of the mobile terminal, however, differs from the adaptive directional BOTTOM so that the weight of the BOTTOM is not set in advance and, thus, consistently rasschityvaet is. Figure 2 adaptive directional BOTTOM are represented by solid lines.

The encoder 342 convolutional code provides a coding to increase the robustness of the data management information. Modulator 344 QPSK modulates the data control information using a modulation scheme QPSK. Although it may be applied to any suitable modulation scheme, in the embodiment, uses a modulation scheme QPSK, with a small number of multiple values of modulation, due to the relatively small amount of data control information.

The signal in the frequency band of the video signal is modulated in an orthogonal modulator 402 RF processor, is limited by the frequency band and then appropriately amplified for wireless transmission.

Figure 5 shows a principle block diagram of a receiver for receiving via the pie BOTTOM. Such a receiver is typically provided in the mobile terminal, may be provided in the base station.

The amplified signal by the mixer 506 and the local oscillator 508 is transferred to an intermediate frequency down conversion). Band-pass filter 510 removes unwanted frequency components. Module 512 automatic gain control adjusts the gain of the amplifier so that the signal level is maintained accordingly. The orthogonal detector 514 orthogonally demodulates using the local oscillator 516, based on the received in-phase (I) and quadrature (Q) component signal. Analog-to-digital Converter 518 converts the analog signal into a digital signal.

The signal passed by the antenna, the RF receiver is subjected to such processes as amplification, frequency conversion, the limitation of the frequency band and orthogonal demodulation, and then converted into a digital signal. The signal from the remote protective intervals is demodulated by the OFDM module 524 fast Fourier transform. The demodulated signal is divided in the divider 526 to the corresponding channels of the pilot, control and data. The pilot channel is inserted in the module channel estimation, which displays the control is in store signal to compensate for changes in the path of propagation. The channel data is compensated using the control signal for each subcarrier range is compressed and converted into a serial signal. The order of the converted signal is changed in the module 536 reverse interleave sample, reverse the changes made in the module alternations. Then the signal is decoded in the decoder 538 turbo code. Similarly, the control channel reimbursed change the channel using the control signal, is compressed spectrum and the channel is decoded in the decoder 540 according to the Viterbi algorithm. After this is done, the signal processing that uses the recovered data and control channels.

Figure 6 shows a principle block diagram of a base station used in a transmission and reception using a multi-leaf BOTTOM. Such a transmitter and receiver, usually provided in the base stations may be provided in the mobile terminal. The elements already described in relation to figure 3, are assigned the same reference symbols and further explanation will not be given. Figure 6, the elements of the processing related to the control channel is omitted. Figure 6 shows the module 602 establish weight transfer; N multiplexers with 604-1 N; N RF transmitters with 606-1 N; N RF receivers with 612-1 N; N dividers with 614-1 N and L modules 616-1 on L setting the weight of the reception.

p> Module 602 establish weight transfer multiplies corresponding weight transfer (weights) and the signals transmitted by the N antennas. Weight transfer are fixed weights provided in advance for the implementation of the multi-leaf BOTTOM.

N multiplexers with 604-1 N fold transmitted signals for each antenna. For example, the multiplexer 604-1 collects from the NDprocessor data channel signals for transmission to the first antenna and adds signals. The multiplexer 604-2 collects from the NDprocessor data channel signals for transmission to the second antenna and adds the signals.

N RF transmitters with 606-1 N carrying out the process for wireless transmission signal for each antenna. The process, which is usually the same as described in relation to figure 4, includes a frequency conversion, the limitation of the bandwidth and gain power.

N RF receivers with 612-1 N carry out operations, which are usually inverse operations in the RF transmitter, converts the signals received by N antennas, the signals suitable for processing in the frequency band of the signal.

N dividers with 614-1 N, conducting transactions, which are usually inverse operations in the multiplexers described above, distribute the signals entered in them, NDprocessor data channel.

L modules 616-1 on L setting vespremi Peremohy weight and reception signals, adopted by the N antennas, and put the signals. This process is performed on each path distribution. In the embodiment, it is assumed L paths of multipath propagation. The folded signal of each pathway is served in the comb synthesizer rake synthesizer, not shown). The processes described above are performed for each subcarrier. Like Libra transmission, the weight of the reception weights are fixed, provided in advance so as to implement multi-leaf BOTTOM. Weight transmission and reception may be the same or different. For example, when using the same frequency for transmission and reception, transmission and reception can be used the same weight, as expected, that the terms of the pathways in the upward and downward communication channels like. Conversely, when used in uplink and downlink communication of different frequencies can be used in different weights, because the conditions of pathways in uplink and downlink communications may vary.

The processing elements shown in Fig.6, are also used when a base station for transmission and reception uses switchable BOTTOM. In the case described above, the weight of the transmission and reception and multiplexers and splitters differ. As described above, switching of the BOTTOM represents one Il is more fixed directional BOTTOM, included in the multi-leaf BOTTOM. Therefore, the weight transfer to implement switchable BOTTOM of the mobile terminal 1 is weight transfer for a fixed directional BOTTOM (direction 1 orientation, for example)corresponding to the mobile terminal 1. Weight transfer is set in the module 602 multiplying the weight transfer in the first processor 302-1 data channel. Weight transfer for the implementation of switchable BOTTOM of the mobile terminal 2 is weight transfer for a fixed directional BOTTOM (direction 2 orientation, for example)corresponding to the mobile terminal 2. Weight transfer is set in the module 602 multiplying the weight transfer in the second processor 302-2 data channel. When using switchable BOTTOM, they switch for each mobile terminal. Therefore, the multiplexers with 604-1 N output signal related to the first mobile terminal, at one point, and only the signal related to the second mobile terminal at a different point. Similarly, such a process is carried out for the other terminals. Thus, switching the BOTTOM belonging to the first mobile terminal is transmitted at one point, switchable BOTTOM belonging to the second mobile terminal, is transmitted to another point and so on, so that the switchable BOTTOM is switchable to sec the population in time.

To receive the process is typically carried out back process as described above for transmission. In other words, the separator signals, supplied to him at one point, an element for performing processing relating to the first mobile terminal (usually the processor 302-1 data channel), and the signals supplied to it at a different point on the element to perform processing related to the second mobile terminal (typically, the controller 302-2 data channel), etc. In the processor data channel weight receiving multiplied with signals adopted by the respective antennas. The weight of the reception weights are to implement switchable BOTTOM, the corresponding mobile terminal.

7 shows a principle block diagram of a base station used in a transmission and reception using an adaptive directional BOTTOM. Like the transmitter and the receiver 6, the transmitter and receiver, as shown, is usually provided in the base stations may be provided in the mobile terminal. The elements already described in relation to figure 3 and 6 are assigned the same reference symbols and further explanation will not be given. As described above, the adaptive directional BOTTOM direction of orientation is changed adaptively in accordance with the position of the mobile terminal. 7 shows the module 702 ISM is rhenium signal; the controller 704 weight transfer and the controller 706 weight of admission.

Module 702 measurement signal measures the reception power and the incoming direction of the signal received from each antenna, and outputs the measured value to the controller 704, 706 weight transfer and weight acceptance.

The controller 704 weight transfer adjusts, on the basis of measured values of the weight transfer so that the quality of the signal is further improved. The algorithm for the implementation of regulation as described above, may be any suitable optimization algorithm for adaptive antenna array (AAR). For example, the weight transfer can be consistently updated so that any evaluation function related to the quality of the output signal has reached a minimum.

Similarly, the controller 706 weight as well as regulated weight of admission on the basis of measured values so that the quality of the signal is further improved.

The radio resource may vary in frequency, code, transmit power, etc. of the radio Resource can be shared using multiplexing time division (TDM, Time Division Multiplexing, multiplexing frequency division (FDM, Frequency Division Multiplexing) and/or multiplexing code division (CDM Code Division Multiplexing). Private aspects of multiplexing will be discussed below with reference the Oh figure 9 and later. To implement data of high quality are used such schemes as adaptive modulation and coding (AMC Adaptive Modulation and Coding) and automatic repeat request (ARQ, Automatic Repeat reQuest).

The radio resource may vary in frequency, code, transmit power, etc. For the implementation of data of high quality are used such schemes as adaptive modulation and coding (AMC Adaptive Modulation and Coding) and automatic repeat request (ARQ, Automatic Repeat reQuest).

(5) a Pilot channel comprising a signal known to both the transmitter and receiver, is transmitted using adaptive directional BOTTOM. The pilot channel is used to estimate the path of propagation for the signal transmitted by the mobile terminal. Therefore, the pilot channel is a pilot channel allocated to the mobile station.

The base station receives shared and dedicated packet data channels using a multi-leaf BOTTOM or toggle BOTTOM. The pilot channel received with pie BOTTOM to evaluate pathways for shared and combined Cana is s control. Furthermore, the pilot channel is also taken using a multi-leaf BOTTOM or switchable BOTTOM for the evaluation of pathways for shared and dedicated packet data channels. This scheme allows to reduce the processing load on the base station, because you don't have to calculate each time the weighing factor for the implementation of the BOTTOM.

Furthermore, the pilot channel is also taken using adaptive directional BOTTOM for the evaluation of pathways for shared and dedicated packet data channels. This scheme gives you the ability to send and receive data channels with high quality, since they are made using adaptive directional BOTTOM.

Therefore, satisfactorily that this scheme can implementing the VAT multilobe BOTTOM, without pie BOTTOM or adaptive directional BOTTOM. Thus, the type of BOTTOM can be reduced.

In the receiving circuit 4 General and combined control channels are taken using multi-leaf BOTTOM or toggle BOTTOM. Shared and dedicated channels packet data are taken using adaptive directional BOTTOM. The pilot channel is received using a multi-leaf BOTTOM or switchable BOTTOM for the evaluation of pathways for shared and dedicated packet data channels.

An implementation option 3

Now describes multiplexing (first overall, second dedicated or shared) of the pilot channel (total or combined) on the control channel and (shared or dedicated) channel data. The multiplexing is performed using at least one of the multiplexing time division (TDM)multiplexing frequency division (FDM) and multiplexing code division (CDM). TDM and CDM is implemented in the multiplexer 306 in peredach the ke figure 3, 6 and 7 and the multiplexer 912 figure 9.

FDM is carried out in a series-parallel converters 328, 348, etc. in the transmitter of figure 3, 6 and 7. In accordance with the foregoing, the multiplexed signals are separated in a parallel-serial Converter 532 figure 5, 1012 figure 10, etc. in the receiver. While TDM switches one by one many multiplexing signals, FDM and CDM add many multiplexing signals. Note that these different aspects of multiplexing are only examples, so they are not given in the sense of the constraint.

On figa and 11B shows an example of multiplexing the pilot channel and data channel. On figa shows how the pilot channel and the data channel are multiplexed in time. Therefore, it is more useful to introduce the pilot channel in the frequency direction, when the strong influence of frequency selective fading. The reason is that the use of alternation in the frequency direction makes it possible to reduce deterioration of the transmission quality. On FIGU shows how the pilot channel and the data channel are multiplexed in frequency.

On figa and 12B shows a diagram of the first example of multiplexing the pilot channel, the channels of the Board and data channels. On figa shows how these channels are multiplexed in time. As described above, from the point of view of taking into account the influence of frequency selective fading, more preferably multiplexing so. If necessary, the multiplexing of data channels, they can be multiplexed in time or multiplexed code division. On FIGU shows how the pilot channel and the control channel are multiplexed in frequency, the pilot channel and the data channel are multiplexed in frequency and control channels and data are multiplexed in time.

On figa and 13B shows a diagram of a second example of multiplexing the pilot channel, control channels and data channels. On figa shows how the pilot channels and control multiplexed on the frequency and how they are multiplexed in time with the data channels. Example figa, where the data channel requires only a single period, a preferable example figa, which shows a two-character period required before the data channel. On FIGU shows how the pilot channels, and control data are multiplexed in time and as control channels and data multiplexed in frequency.

An implementation option 4

In the following embodiment, for the upward communication channel used multiple access code division multiplexing with variable coefficients of expansion of the range and repeat elementary sequences (Variable Spreading and Chip Repetition Factors - CDMA, VSCRF-CDMA). The transmitter and receiver in this case is basically the same as the transmitter and receiver for DS-CDMA, described with respect to figures 9 and 10, but differ from them in processing, atacamas the expansion and compression of the spectrum.

On Fig shows the block diagram of the expansion module spectrum used in the transmitter VSCRF-CDMA. Thus, the following describes the operation of the expansion module spectrum is commonly performed in the mobile terminal. The extension of the spectrum may be used instead of module 908 and/or 910 expansion of the range of figure 9. The expansion module spectrum includes a module 1602 code multiplication, iterative synthesizer 1604 and the phase shifter 1606.

Code multiplier 1602 multiplies code spread spectrum and transmitted signal. On Fig code forming channels defined by a predetermined coefficient code spread spectrum (SF), multiplied by the module 1612 the multiplication of the transmitted signal. In addition, the code is multiplied by the scrambling module 1614 the multiplication of the transmitted signal.

Iterative synthesizer 1604 compresses in time transmitted signal is spread spectrum and repeats the process preset number of times (CRF times). Properties and operations for the case where the number of repetitions CRF is 1, the equivalent occasion of DS-CDMA is described in connection with figures 9 and 10 (for CRF=1 in the phase shifter is not required phase shift).

The phase shifter 1606 shifts the phase of the transmitted signal with a predefined frequency. The amount of phase shift is set for each mobile terminal separately.

On Fig shown b is OK-scheme of the compression module spectrum used in the transmitter VSCRF-CDMA. The compression module spectrum can be used instead of the compression module spectrum figure 10. Thus, the following describes the operation of the compression module of the spectrum are typically implemented in the base station. The compression module range includes Phaser 1702, an iterative synthesizer module 1704 and 1706 of the code compression spectrum.

Phaser 1702 multiplies the received signal and the magnitude of the phase that is set for each mobile terminal, and separates the received signal into the corresponding mobile terminal signals.

Iterative synthesizer 1704 extends in time repeated data and reconstructs data that is not compressed.

Module 1706 code range compression compresses the range by multiplying the received signal and the code spread spectrum for each mobile terminal.

On Fig shows a view for explaining the main operations of the VSCRF-CDMA. For convenience of explanation, the group of the data stream signal with the advanced code the way spectrum is expressed as d1d2, ..., dQwhere the time period for an individual item of data di(i=1, ..., Q) is equal to TS. One data element of the d1can be assembled into a single symbol, or any other suitable information. One group of signal streams has a total time period corresponding to TS×Q. the Flow 1802 signal ratio is esthet signal, introduced in the iterative synthesizer 1604. The flow signal is compressed in time CRF times and converted so that the compressed signal is repeated in time period Ts×Q. the Transformed stream signal as shown 1804 on Fig. On Fig also shows the period of the guard interval. The compression time can be carried out using frequency, which in CRF times higher than the clock frequency used for the input signal, for example. Thus, a separate time period of the data d1is compressed to TS/CRF (repeated CRF times). The compressed and repeated flow 1804 signal derived from an iterative synthesizer 1604, is injected into the phase shifter 1606, is shifted in phase by a predetermined value and displayed. The amount of phase shift is set for each mobile terminal, is set so that the corresponding signals of the upward communication channel belonging to the mobile terminal, are pairwise orthogonal along the frequency axis. Thus, the frequency spectrum of the signal in the uplink communication channel or received by the base station, usually should be as shown in 1806 on Fig. Bandwidth is shown as the width of the expansion of bandwidth is the bandwidth that must be taken if the thread 1802 signals with spread spectrum is transmitted as it is. With Aty in time and repeated spectrum of the output signal of iterative synthesizer 1604) occupies a narrow band of frequencies, which is common to all mobile terminals. Sliding a narrow strip on the phase value, specific to the mobile terminal, makes it possible to prevent overlapping frequency bands with each other. In other words, compression of time, repetition and phase shift allow you to install the appropriate mobile terminal bands narrow and arrange them in a comb-toothed shape, making thus possible the implementation of orthogonality along the frequency axis.

Now the operation, the reverse operation in the transmitter is performed in the receiver. In other words, in accordance with the magnitude of the phase shift for each mobile terminal in the Phaser 1702 on Fig adopted phase signals are provided to input in an iterative synthesizer 1704. The inputted signal is expanded in time, is converted into a stream of signals with extended spectra and derived from iterative synthesizer 1704. The range compression is performed on the signals by multiplication with pre-code spread spectrum module 1706 compression of the spectrum. Thereafter, subsequent processes are carried out using the already described elements.

Coefficient code spread spectrum SF under option exercise appropriately set in accordance with the communication environment. More specifically, to efficient code spread spectrum SF can be set based on one or more of (1) the conditions of propagation; (2) the configuration of the cell; (3) the volume of the data stream, and (4) the parameters of the radio communication. Coefficient code spread spectrum SF can be installed on the base station or mobile terminal. To determine the degree of code spread spectrum preferably at the base station in the case of information managed by the base station, such as the volume of data flow.

(1) the conditions of propagation can be estimated by measuring the distribution of the delay or the maximum Doppler frequency. Distribution delays S can be calculated in accordance with the following expression on the basis of the delay profile, as shown in Fig, for example:

Here P(τ) represents the power. In addition, the maximum Doppler frequency can be determined by calculating the scalar product of two spaced-time signals that have the same content. For example, when the pilot channels are multiplexed in time, the pilot channels of input at different time intervals, can be used as shown in figa. When the pilot channels are multiplexed code division may be used for the first and second half-periods of the pilot channels as shown in figv. In any case, if the time variation is large, the scalar is proizvedenii different time of the pilot channels is small, and if not, then Vice versa. At constant time would be the maximum value of 1.

It is desirable that the coefficient of code spread spectrum for the frequency domain were set to small, because the more the distribution of the delay, the more changes in the frequency domain. Conversely, it is desirable that the coefficient of code spread spectrum for the frequency domain were set great for small distribution delays. It is desirable that the coefficient of code spread spectrum to the time domain were set to small, because the more the maximum Doppler frequency, the more changes in the time domain. Conversely, it is desirable that the coefficient of code spread spectrum to the time domain were set great for low Doppler frequency.

(2) the configuration of the cell includes a communication environment with many hundreds or individual hundredth, and indoor environment, for example. Many hundred, it is desirable to make the ratio of code spread spectrum large to suppress the interference from other cells. Conversely, in an isolated cell or the environment in the room where there is no need to take into account such interference, it is desirable to set the ratio of code spread spectrum low or equal 1. The definition of site configurations can be reported together with some separately give is a subject to the control signals based on the received signal. In the latter case the assessment is carried out by measuring the power of interference from surrounding cells. For example, when using the pilot channel, multiplexed in time, the assessment is carried out by subtracting the power relating to the pilot channel (desired wave)from the total power of the signal (desired wave + undesired wave) inside the frame (time frame). The scheme ignores thermal noise included in the calculated value, because its amplitude is small. When the pilot channels are multiplexed code division, the power of interference from surrounding Ares can be calculated in a simple way, ignoring the interference at his own cell. More precisely, the power of interference from surrounding Ares can be estimated using preliminary calculation of the interference level of the own cell and subtracting the level of the total interference power. On the other hand, the pilot channels with extended code image spectra can be transmitted by multiplexing in time to ensure that interference of the pilot channel of the own cell are avoided.

(3) the Coefficient of expansion of the range may vary based on the volume of data flow, the number of users, baud rate, etc. for Example, for a large number of users, the coefficient of expansion of the spectrum can be set large to suppress mutual interference.

<> (4) the Coefficient of expansion of the spectrum may be installed in accordance with the parameters of the radio communication, such as the modulation scheme and the level of the code channel coding. For example, when employing adaptive modulation and coding (AMC Adaptive Modulation and Coding), can be prepared listing the table, which refers to the quality of the received signal, and the parameters (i.e., the modulation scheme, the degree of code and rate code spread spectrum SF) so that they are adaptive to change.

FIELD: information technology.

SUBSTANCE: methods of reporting channel quality indicators (CQI) are described. Data activity at a receiver may be determined, and CQI reporting by the receiver may be adjusted based on the determined data activity. In one design, CQI reporting may be enabled for a time window around each expected packet arrival for a periodic or quasi-periodic transmission and may be suspended outside of the time window. In another design, CQI reporting may be varied based on ACK/NACK feedback. In yet another design, CQIs may be sent at a first rate when data activity is not detected and at a second rate faster than the first rate when data activity is detected. In yet another design, CQIs may be sent only during discontinuous transmission (DTX) ON periods when data activity is not detected and may be sent during both DTX ON and OFF periods when data activity is detected.

EFFECT: efficient channel quality reporting in wireless communication system.
