Abstract

In a code division multiple access communication system, a method and apparatus provide for an efficient testing of operating behavior of quality indicator bit. The method and the accompanying apparatus include configuring a receiver to expect to receive a communication channel at full data rate, and transmitting a signal from a transmitter to the receiver. The signal is carrying the communication channel at a data rate other then said full data rate, and at a power level for receiving at the full data rate. Consequently, the receiver fails to receive the communication channel at the data rate. A received signal to noise ratio of the received signal at the receiver is determined. A value of the quality indicator bit is determined based on the determined signal to noise ratio. The determined value of the quality bit is communicated to the transmitter.

Description of the invention

The invention relates to communication. 2 Wireless communication systems with parallel access and code compression of channels (PDCU or SOMA) have been described in various standards published by the Telecommunications Association of USA. Specialists know these standards as

TIA/AIR INTERFACE/18-2000, TIA/AIR INTERFACE/95А/В and M/SOMA, etc. Copies of these standards can be obtained from pEr:/Limlu.sdd.oga or from TIA, Ziapdagaz apa Tesppoiosdu Oeragitepi. 2500 UMivop

A section of one of these standards defines the verification of the operation of devices operating according to the requirements of each of the standards. A section in these standards provides a detailed description of embodiments that implement a simplified bit quality indicator (BQI) verification procedure. According to this, there is a need to improve the communication system.

A method and a device for effectively checking the functioning of the BIA in the system with PDKU are proposed. This method and 72 corresponding device include adapting the receiver to receive the communication channel at full transmission speed and transmitting the signal from the transmitter to the receiver. This signal carries a communication channel with a transmission rate other than full and with the power required to receive at full transmission rate. As a result, the receiver cannot receive the communication channel at full transmission speed. In the receiver, the signal-to-noise ratio of the received signal is determined, and through this ratio, the BIiY value is determined, which is transmitted to the transmitter.

The new improved method and the corresponding device ensure the effective implementation of the verification procedure in the transmitter and receiver in the communication system with the PDKU. One of the typical embodiments described herein is intended for use in a digital wireless communication system. Other embodiments may be used in different environments and configurations. In general, the systems described here can be implemented using programmable processors, integrated circuits, or discrete logic. Data, instructions, commands, information, signals, symbols -- and code elements referred to in the description may be represented by voltages, currents, electromagnetic Ge) waves, magnetic fields or particles, optical fields or particles, or combinations thereof. In addition, blocks of the scheme of operations can be implemented schematically or as operations of a method. in

Fig. 1 contains a general block diagram of a communication system 100 capable of operating according to one of the standards of PDKU and according to various embodiments. In general, the system 100 includes a base station (BS) 101, which provides communication channels between multiple mobile stations (MS), for example, 102-104, and between the MS 102-104 and the backbone network 105. The BS 101 may also include a number of components, for example, the MC controller, the C 70 controller, all RF transceivers (these components are not shown). BS 101 can communicate with other BOS. BS 101 s maintains communication with each MS through a direct communication channel. A direct channel can be provided with a signal

From" the direct channel from BS 101. The direct channel signals intended for MS 102-104 can be combined to form the direct channel signal 106. Each of the MS 102-104, receiving the signal 106 of the direct channel, decodes it to obtain information addressed to the user. At the receiving end, the receiver may consider the signal blank 106 addressed to others as interference. and MS 102-104 maintain communication with BS 101 through the reverse communication channel, each of which is formed by a signal

Ge") (for example, signals 107-109 for MS 102-104)) of the return channel. BS 101 can transmit in the pilot channel of the direct channel to all MCs a predetermined sequence of data bits, which helps each MC to decode the signal 106 - the direct channel. Each of the MS 102-104 can transmit a pilot channel to the BS 101, which can be used to decode the information carried by the reverse channel signal transmitted by this MS. The use and operation of the pilot channel are well known to specialists. Each MS 102-104 and BS 101 have a transmitter and a receiver to maintain communication through forward and reverse channels.

Fig. 2 contains a block diagram of the receiver 200, which is used for processing signals of the PDKU. The receiver 200 demodulates the received signal to obtain the information that the signal carries. Accepted samples are stored in 22 random access memory (RAM) 204. Accepted samples are generated by the RF/intermediate system 290

HF) frequency (RF/PU) and antenna system 292. Antenna system 292 receives the RF signal and directs it to the RF/IF system 290, which may be a conventional RF/IF receiver. Received RF signals are filtered, their frequency is reduced and they are digitized with the formation of received samples at modulation frequencies. The samples arrive at the demultiplexer 202, the output of which is sent to the search node 206 and elements 208 of parallel processing 60 ("fingers"), with which the control node 210 communicates. The connector 212 connects the decoder 214 to the finger elements 208. The control node 210 can be a microprocessor controlled program and can be part of the same integrated circuit or be implemented as a separate integrated circuit.

In operation, the received samples are sent to the demultiplexer 202, which sends them to the search node 206 and the fingers 208. The control node 210 uses the elements 208 to demodulate the received signal 62 with different time shifts based on the search results received from the search node 206.

The demodulation results are combined and sent to the decoder 214, which decodes them and outputs the decoded data.

In general, the search node 206 can use incoherent demodulation of the pilot channel to test the timing hypothesis and phase shifts corresponding to different transmission sources and paths. The demodulation performed by the finger elements 208 can be performed as a coherent demodulation of other channels, for example, control and information channels. The information obtained by the search node 206 by demodulating the pilot channel can be used in the finger elements 208 to demodulate other channels. Search node 206 and finger elements 208 can perform both pilot channel search and 7/0 demodulation of control and information channels. Demodulation and search can be performed with different time shifts. The demodulation results can be combined in combiner 212 before decoding the data of each channel. Convolution of the channels is performed by multiplying the received samples by the complex conjugate of the pseudo-noise (PS) sequence and the assigned Walsh function according to one time hypothesis, followed by digital filtering of the received samples by an integrated circuit (not shown). Such a procedure is well known. Receiver 200 can be used in BS 101 and MS 102-104 to decode signal information of the reverse and forward channels, respectively. BS 101 can have several receivers 200 for decoding information transmitted from several MS at the same time.

Receiver 200 may also reduce interference through a correlation procedure. Received samples read from KAM 204 undergo correlation processing for each received signal. The correlation process can generally be described as the operations of the search node 206, the finger element 208, and the combiner 212. Since the received samples include signal samples from multiple transmission sources, the correlation process can be repeated for each received signal. The correlation process for each received signal may be unique, as each signal may require separate correlation parameters, namely those used by the search node 206, the finger element 208, and the combiner 212. Each signal may include an information channel and a pilot channel. PS sequences assigned to information and pilot channels carried by each signal can be different. The correlation process may include channel estimation, i) that is, estimation of channel fading characteristics based on the result of correlation with the pilot channel. A channel score can be used to correlate with an information channel. After that, each information channel is decoded. The result of each correlation process can be decoded in the decoder 214. If the transmitted channel has been convolutionally encoded, the decoding operation 214 is performed according to the applied convolutional code. If the transmitted channel has been turbo-coded, the decoding operation 214 is performed according to the applied turbo code.

The decoding of each signal provides sufficient information to determine whether a pass indicator was generated for each CCN check associated with each transmitted data frame. The use of KCN in electronic communication systems is well known to specialists. If the CCN passes, the result of channel decoding is related to it

KCN, can be transferred to further acceptance operation. To evaluate the quality of the signal can be used BIA, which can be transmitted to the power control subchannel of the reverse channel and indicate the quality of the forward dedicated channel (DSC). If a direct primary channel is used, the BIL is set similarly to the erasure indicator bit (EBI), which may indicate an erased channel frame and/or no transmission of a channel frame.

Signals received by BS 101 can be sent to receiver 200. Antenna system 292 of RF/IF system 290;" receives signals from the MS and forms samples of these signals, which can be stored in the CAM 204. The receiver 200 can include several search nodes 206, several finger elements 208, several combiners 212 and several decoders 214 for simultaneous implementation of the correlation procedure and decoding of all signals, adopted from -I different MS. However, it is necessary to have only one 292 antenna system and one 290 RF/IF system.

With each start of the correlation process, the search node 206 and the finger element 208 start anew

Me, the procedure for determining the incoherent modulation of the pilot channel for testing the time hypothesis and phase shifts. - The search node 206 or the finger element 208, or the search node 206 and the finger element 208 together 5r Can determine the signal-to-noise ratio (S/N) for each received signal. The EB/I ratio is synonymous with the S/W ratio and is a measure of signal energy relative to interference per unit data symbol or data bit. So,

Ge EBL and S/Sh can be interchangeable. Interference (I) can be defined as power spectral density and thermal noise.

To control interference, the system monitors the level of the signal transmitted from each transmission source, or the transmission rate of the communication channel, or both. In general, each MS determines the required power level of the reverse sofa to maintain both information and pilot channels. Different ones are known

Ф) schemes for controlling the signal transmission power from the MS. The output power level of each MC is controlled by two independent control circuits - closed and open. The open-loop power control is based on the need for each MS to maintain adequate communication with the BS. Therefore, the MS, which is closer to the BS, needs less power than the more distant MS. A strong signal received at the MS indicates less loss when passing between the MS and the BS and therefore requires a lower transmission power level of the reverse channel. In an open loop control, the MS sets the transmit power level of the return channel based on independent S/W measurements of at least one received channel, for example, the pilot channel, the calling channel, the synchronization channel, and the information channel. The MS can perform such measurements before setting the reverse channel transmission power 65.

Fig. 3 contains a scheme 300 operations of a typical method of power control in a closed circuit. The procedure 300 of such control begins when the MS of the communication system 100 finds a direct information channel. After the initial access attempt, the MS sets the initial power level of the reverse channel. This initial level is then adjusted by a closed-loop power control. Closed-loop power control procedure 300 is faster than open-loop power control. Procedure 300 provides a correction for open-loop power control. Procedure C00 is performed together with open-loop control during the existence of the information channel to ensure control of the power of the reverse channel in a significant dynamic range.

At the beginning of the procedure 300 BS 101 measures the S/W ratio (operation 301) for the return channel signal /o transmitted from the MS. The measured S/S is compared with the set S/S (set S/S). The measured S/W can be represented by EB/, i.e. the ratio of bit energy to interference, and the set value can have the appropriate form. The setpoint is selected for the MC and may initially be based on the MC's set open-loop power level.

If the measured S/W exceeds the set value (oper. 303), the BS 101 instructs the MS to reduce the level of 7/5 of the forward channel power by a certain value, for example, uB. When the measured S/W exceeds the set value, it indicates that the MS is transmitting in the reverse channel with a power higher than that required to maintain proper communication in the reverse channel. The instruction for the MS to reduce the signal power level is aimed at reducing the overall interference in the system. If the measured S/W is lower than the set value, operation 304 of the BS 101 instructs the MS to increase the signal power level of the reverse channel by a certain value, 2o, for example, uB. When the measured S/W is lower than the set value, it indicates that the MS is transmitting in the reverse channel with a power level insufficient to maintain adequate communication. By increasing the transmission power, the MS can overcome obstacles and ensure the proper level of communication in the reverse channel.

Operations 302-304 can be considered as power control in the inner loop. This control holds

The N/W of the return channel in BS 101 is as close as possible to the desired threshold determined by the set value. high school

The desired S/W is based on the set value selected for the MC. Power up or down can happen several times during a frame. One time frame can be divided into 16 control groups and) power. Each such group consists of several data characters. The command to decrease or increase the power can be transmitted 16 times per frame. If one frame of data has not been received (operation 305), the power control loop 300 continues to measure the reverse channel N/W during the next power control group c zo (operation C01). The process is repeated (operations 302-304) until at least one frame is received from the MS.

One set or desired value may not be sufficient for all conditions. Therefore, the set c value can be changed (operation 302) depending on the desired frequency of frame errors in the reverse channel. "-

If one frame of data has been received (operation 305), operation 306 may calculate a new set value, which becomes the new desired N/W value for the MO. The new set value may depend on many factors, including the frequency of frame errors. For example, if this frequency exceeds a predetermined threshold (which indicates an unacceptable error rate), the set value can be increased. As a result of this increase, the MS increases its transmission power level in the reverse channel through the comparison operation (302) and the instruction to increase the power (operation 304). If the frame error rate is lower than the threshold (indicating an acceptable error rate), the MS lowers its transmit power level in the reverse channel through a comparison operation (302) and a power increase instruction (operation 303). Operations 305-306, returning from operation 306 to operation 302 to determine the new set value and measuring (operation 301) the B/W of the new frames can be considered as outer loop operations. This power control circuit can provide ;" one command in each power control group. One frame and one power control group can have a duration of 20 and 1.25ms, respectively.

To reduce interference, the system can use a power control scheme in the direct channel. MS-I periodically informs BS about the quality of voice and data transmission. The frame error rate and quality measurement are sent to the BS in the power measurement message. This message contains the number of received z

Me. frame errors in the direct channel during the interval. The power level of the direct channel signal is adjusted taking into account the number of frame errors. Since this feedback is based on the frame error rate, this reverse channel power control mode is significantly slower than the reverse channel power control. To speed up the response, an erasure bit can be used, which will inform the BS about

Whether the previous frame was received with or without errors. The transmit power level can be adjusted continuously while monitoring messages or erasure bits.

When transmitting data, the direct channel can be transmitted to the MS with a fixed power level and with an adjustment of the effective desired transmission rate of the direct channel. Adjusting the transmission rate of the forward channel for the system as a whole is a form of interference control. It should be noted that the purpose of power control (F, direct channel) is to control interference in the service area and/or to share limited communication resources. When the return transmission of quality measurement results indicates poor reception, the data rate can be reduced while maintaining a constant transmission power to neutralize the effects of interference The transmission rate may also be reduced to allow other MSs to receive direct channel signals at a higher rate.

In addition to the closed and non-closed power control loops, the MS can adjust the output power level by the attributes of the code channel according to the requirements of the standard. The MS may set the output power of the enhanced access couch header, enhanced access channel data, and shared control data 65 of the reverse channel relative to the output power level of the reverse pilot channel. The output power level of the reverse pilot channel is determined by the closed and non-closed power control loops. The MS supports the ratio between the power levels of the code channel and the reverse pilot channel. This ratio can be determined by the data rate of the code channel. In general, the table provides the value of this ratio for different data transfer rates. In general, this ratio is higher for higher speeds. Ratios of 1 or less may be used. At a ratio of 1, the power level of the pilot channel determined by the power control circuit 300 is equal to the power level of the code channel. During data transmission in the information channel, the transmission speed and power level of this channel can be adjusted. The power level can be selected based on the relative power of the reverse pilot channel. After determining the acceptable data rate, an appropriate level can be set for the information channel 7/o Relative to the power level of the reverse pilot channel.

In the data transmission mode, the BS can provide communication channels for a large number of MSs with different transmission rates. For example, one MS can receive data in the return channel with a low transmission speed, and another MS - with a high one. In the return channel, the BS can receive many signals from different MSs.

Based on independent measurements, the MS may request a desired transmission rate from the BS by transmitting this /5 Request in the Transmission Rate Control (TRC) channel. The BS tries to provide transmission in the direct channel with this transmission rate. In the reverse channel, the MS can autonomously select a transmission rate from among several possible ones. The selected transmission rate can be transmitted to the BS in the return channel of the transmission rate indicator. The quality of service for each MS may be limited to a certain level. Quality of service may limit the maximum possible transmission speed in the reverse and/or forward channel. In addition, 2o data transmission can be continuous, as is the case with the transmission of voice information. A receiver can receive data packets at different intervals, different for different receivers. For example, a receiver may receive data sporadically, while another receiver may receive packets at short intervals.

Communication with higher transmission rates requires more received/transmitted signal power than for lower rates. In the case of voice communication, the forward and reverse channels can operate with the same transmission rates, which can be limited to low values, since the frequency spectrum of the voice is limited. The possible speeds of voice transmission for systems with PDKU are defined by standards, for example, (8)

I8-95, I5-2000, MUSOMA. When transmitting data, the transmission speeds for forward and reverse channels can be different. For example, if the MS receives a large file from the database, the direct channel will be occupied mainly by the transmission of data packets at a speed that can reach 2.5 Mbit/s. The data transmission speed of the direct channel can be determined by the MO requirement. In the reverse channel, the data transfer rate may be lower, ranging from 4.8 to 153.6 kbps. with

In general, in the communication system 100, according to various embodiments, the duty cycle of the communication channel is determined, and the power level of this channel is controlled according to the determined duty cycle. Each transmission in the channel can be a time frame with a duration of, for example, 20ms. The transmission rate of each such frame can be

It should be 1250-14400bit/s. The number of bits in each frame depends on the transmission speed. A channel can serve a user or transmit/receive service signals during a communication session between users. A user in a communication session can use MSs (for example, 102-104), each of which can be a cellular phone. BS 101 can be addressed.

According to the embodiment, the communication channel can be a specialized control channel (SSCN), which can be used for communication with the user and for signaling information to maintain information communication with the user and the addressee, for example, between the MS 102 -104 and BS 101. The number of OSSN frames transmitted. over a period of time may vary depending on use. Time between transmissions of OSSN time frames and? when transferring data can also be different. For example, even when transmitting informational data, the transmission of a frame in a communication channel, for example, OSSN, may not take place. In another situation, several frames can be transmitted in a short time in a communication channel, for example, OSSN. Therefore, the work cycle of frame transmission in -I communication channel, for example, OSSN, can be different at different times.

The BIA verification procedure can consist of three parts that may overlap. Simplified procedure

Me, can be implemented in different embodiments. The behavior of the IDS for the Direct Dedicated Control Channel can - be implemented in the Direct Dedicated Control Channel for MSs that support a channel configuration that does not involve a Direct Main Channel. During the check, a closed circuit can be activated to control the power of the Direct Information Channel in the BS. When working in the EMF MOOPE mode, which is equal to "100, i

If the channel configuration does not include the Direct Main Channel, the MS monitors the Direct

Specialized Channel and sends BIA. For active personnel, BIA has the same meaning as BIS. When the frame is inactive, BIA indicates the quality of the channel. In certain tests, the procedure checks whether the MS sends a BIP with the same value as the BIS for active frames. In other tests, it is checked whether the MS sends a BIP according to the quality of the received signal for inactive frames that contain only power control bits (ie, do not carry (F) data). ka Measurements may include: - connecting the BS generator and AMUOM to the conductor of the MS antenna according to Fig. 6b.5.1-4 of the specification, v - configuring the MS to work in each class of bands supported by the MS, and performing operations 3-8, - if MS supports demodulation of Radio configuration 3, 4 or 5, establishing a communication session using

Mode C of the Specialized Control Channel Test and performing operations 5-8, - if the MS supports demodulation of Radio Configuration b, 7, 8 or 9, establishing a communication session using Mode 7 of the Specialized Control Channel Test (see 1.3) and performing operations 5- 8, 65 - setting the test parameters for Tests 1, C, 5, 7, 9, 11 and 13 according to Table A.2.13.1-7 and sending alternating full and bad frames (2 Ohms) with data, and full frames are sent by a BS simulator at 9600 or 14400bps and bad frames by a BS simulator (1) at 1500 or 1800bps in the Main Direct Channel with the same test radio configuration, or (2) at 9600 or 14400bps using the radio configuration , different from the test one, - verification of the received BIR in the BS with a comparison with the corresponding frames received by the MS for at least 100 frames, - setting test parameters for Tests 2, 4, 6, 8, 10, 12 and 14 according to Table A.2.13 .1-1-A.2.13.1-7 and alternate switching on and off p frame transmitters with power control bits in Direct only

Specialized Control Channel, 70 - verification of the received BIA in the BS for at least 100 frames.

The minimum standard for certain tests may include verifying that alternate BIA results of "OO and "7 repeat the alternation of good and bad frames, respectively, with an accuracy of 95905. For other tests, the minimum standard may include verifying that alternate BIA results of "0 and 7 repeat the alternation of switching on and off the transmission of frames, respectively, with a reliability of 95905. paramet | Oda | 00000001» p UM MY PO PO pev (ninformational Boyo; dB (nasdbbetter than iZvEEKUAMOMI (sun better than nzh tag UAMOM land No: NYM NIM pot.
