A detailed description of the preferred option(s)

Generally speaking, a new and improved method and apparatus is proposed for efficient test execution process in the transmitter and receiver in the communication system, multiple access, code-division multiplexing. One or more exemplary embodiments described herein are described in the context of the digital broadcast data. Despite the fact that the use in this context is primary, other embodiments of the invention may contain other environments or configurations. Generally, the various systems described herein may be formed using a processor controlled by software, integrated circuits or discrete logic circuits. Data, instructions, commands, information, signals, symbols and elementary signals, which can be referred to by su is th application mainly represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or a combination thereof. In addition, the blocks shown in each flowchart, can provide technical support or stages of the method.

Figure 1 illustrates a General block diagram of a system 100 connection made with the possibility of work in accordance with any of the standards of communication systems, multiple access, code-division multiplexing (mdcr) and in accordance with the variations in implementation. Typically, the communication system 100 includes base station (BS) 101, which provides a line of communication between a number of mobile stations such as mobile stations 102-104, and between the mobile stations 102-104 and wired network 105. BS 101 may include a number of components such as the controller of the mobile station, the base station controller and a radio frequency transceiver. For simplicity, such components are not shown. BS 101 may also communicate with other base stations (not depicted). BS 101 communicates with each mobile station 102-104 via direct line of communication (base station-mobile station). A direct link can be maintained by using a signal direct line of communication transmitted from the BS 101. Signals direct line of communication that is addressed to multiple p the wheel stations 102-104, can be summed for signal 106 a straight line. Each of the mobile stations 102-104, receiver 106 a straight line, decodes the signal 106 a direct line of communication to retrieve information, which is addressed to its user. On the receiving end of the receiver can be considered as the interference portion of the received signal 106 a direct line of communication addressed to others.

Mobile stations 102-104 are in communication with BS 101 through the corresponding return line connection (mobile station - base station). Each return line connection is supported through the signal return line connection, such as signals 107-109 return line connection for the respective mobile stations 102-104. BS 101 may also transmit a predetermined sequence of data bits in the channel pilot signal through a direct line of communication to all mobile stations to help each mobile station when the decoding signal 106 a straight line. Each of the mobile stations 102-104 may transmit the pilot channel signal in the BS 101. Channel pilot signal transmitted from the mobile station can be used to decode the information, the portable signal return line communication transmitted from the same mobile station. The use and operation of the signal, the pilot signal is well known. The transmitter and receiver to implement the program through direct communication and a return line connection included in each mobile station 102-104 and BS 101.

Figure 2 illustrates a block diagram of a receiver 200 that is used for signal processing mdcr. The receiver 200 performs demodulation of a received signal to extract the information carried by the received signal. Sample (Rx) receiving stored in the RAM 204. Sample reception are generated by the system 290 radio frequency/intermediate frequency (RF/if) and system 292 antenna. System 292 antenna receives the RF signal and transmits the RF signal to the system 290 RF/if frequencies. The system 290 RF/if frequencies may be any conventional receiver RF/if frequencies. Received RF signals are filtered, converted with decreasing frequency and converted into digital form to generate a sample of RX in the main band of frequencies. Samples are submitted to the demultiplexer 202. The output signal of the demultiplexer 202 is fed into the device 206 search and elements 208 finger (elements-bends). The device 210 control connected with them. A combiner 212 connects the decoder 214 with elements 208 finger. The device 210 can be a microprocessor controlled by software, and can be located in the same integrated circuit or on a separate integrated circuit.

During operation, sample reception is served in the demultiplexer 202. The demultiplexer 202 delivers the sample to the device 206 search and elements 208 finger. The device 210 control configures the elements 208 Phi is Hera so, to perform demodulation of a received signal with different time shifts based on the results of the search from the device 206 search. The demodulation results are combined and transmitted to the decoder 214. The decoder 214 decodes the data and outputs the decoded data.

Usually to search for the device 206 can search to use a non-coherent demodulation of the pilot channel signal for testing the hypothesis synchronization and phase shifts that correspond to different sources of transmission and multiple routes (routes multipath propagation). Demodulation is performed by means of the elements 208 of the finger can be performed via coherent demodulation of other channels, such as the control channel and the channel traffic. Information extracted from the device 206 search, using a demodulation pilot channel signal can be used in elements 208 finger for demodulation of other channels. The device 206 search and other elements 208 finger can provide as a search channel pilot signal and demodulation of the control channel and traffic channels. The demodulation and the search can be performed with different time shifts. The results of demodulation can be combined in the combiner 212 before decoding data transmitted in each channel. Compression channels is performed by multiplying the received samples of the and the complex conjugate of the number sequence PN (pseudocode) and the assigned Walsh code when one hypothesis synchronization and digital filtering of the resulting samples, often using integration schemes and accumulation (not shown). This method is well known in the art. The receiver 200 may be used in the BS 101 and the mobile stations 102-104 for decoding, respectively, the signals straight line and the return line. BS 101 may use multiple receivers 200 to decode information transmitted from multiple mobile stations at the same time.

Receiver 200 may also perform damping of the interference through a process of correlation. The adopted sampling after read from the RAM 204, passed through a process of correlation for each received signal. The correlation process can be jointly described as the operation of the device 206 search element 208 of the finger and the multiplexer 212. Since the received samples contain samples of the signals transmitted from more than one source of transmission, 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 a different correlation parameters as the parameters found in the operations of the device 206 search element 208 of the finger and the multiplexer 212. Each signal may include the channel traffic and pilot channel signal. The PN sequence assigned to channel traffic and pilot channel signal, portable, what each signal, may be different. The correlation process may include evaluation of the channel, which includes evaluation of the characteristics of the fading channel on the basis of the correlation with the pilot channel signal. Information of channel estimation is used for correlation with the channel traffic. Each channel traffic then decoded.

The result of each correlation process may pass through the decoding process in the decoder 214. If the passed channel-coded through a process of convolutional coding step 214 decoding is performed in accordance with the used convolutional code. If the passed channel-coded through a process of turbomotive, step 214 decoding is performed in accordance with the used turbo code.

Each signal can be decoded to provide enough information about whether the flow indicator for each control cyclic redundancy code (CRC)associated with each transmitted data frame. Operation and use of the CRC in the communication system are well known. If the CRC fails, the decoded result of the channel associated with no CRC, may be referred for additional surgery reception. Bit indicator of quality (BOD) can also be used to indicate the signal quality. BOD can be transmitted over podca the Alu power control feedback line to indicate the quality of the signal over a dedicated control channel (QMS) is a straight line. When the present main channel of direct communication line, BOD is set to indicate the same thing that the bit rate of the Erasure. Bit rate erase can specify erased frame channel and/or absence of transmission of the frame channel.

Signals received via BS 101 may be introduced into the receiver 200. System 292 antenna and system 290 RF/FC receive signals from mobile stations in order to create a sampling of received signals. Accepted sample may be stored in RAM 204. The receiver 200 may include a number of devices 206 of the search, the number of elements 208 of the finger, the number of combiners 21 and the row decoder 214 for simultaneous execution of the correlation process and the decoding process for all of the signals received from different mobile stations. However, only one system 292 antenna and system 290 RF/if frequencies may be necessary.

Each time you begin the process of correlation, the device 206 search and element 208 finger can start anew to determine non-coherent demodulation pilot channel signal in order to test the hypothesis synchronization and phase shifts. The device 206 search, or element 208 finger or device 206 search and element 208 finger in combination can determine the signal-to-noise (s/n) for each received signal. The ratio Eb/I in meaning may be the same with the ratio C/W. the Ratio Eb/Iyavlyaetsya energy signal relative to the noise per unit data symbols or data bits. Consequently, the s/n and Eb/I can be used interchangeably in some aspects. Interference (I) can generally be defined as the spectral density of the interference power and thermal noise.

In order to manage interference, the system controls the level of the signal transmitted from each transmission source, or the data rate of the communication line or both. Usually the PS determines the required power level of the reverse link, to support the trafc channel and the pilot channel signal. There are various schemes for power control to control the power levels of signals transmitted from the substation in the communication system. The output power of each substation is controlled by two independent control loops, open loop (without feedback) and closed loop (with feedback). Capacity management using open path based on the need of each substation to maintain adequate communication with the BS. Therefore, PS, closer to the BS, requires less power than more remote substation. A strong signal in the PS indicates lower losses distribution between PS and BS and therefore requires a lower level of transmission power of the reverse link. When power control using open path SS sets the level of transmit power of the reverse communication line on the basis of an simich measurements/W of at least one of the received channel, such as the pilot channel signal, the paging channel, the channel synchronization and channel traffic. PS can perform independent measurement before installing the power level of the reverse link.

3 illustrates a flowchart 300 of an exemplary method of power control using closed loop. The operation of method 300 power control using closed loop begins when the COP in the communication system 100 captures the channel traffic straight line. After the initial access attempts using PS PS sets the initial power level of the reverse channel link. The initial setting of the power level in the return line then regulated during the communication line by controlling the 300 level power using a closed loop. Management 300 power level using a closed loop operates with a faster reaction time than the control with open loop. Management 300 power using a closed loop corrects the power control using an open path. Power control using closed loop works in conjunction with management with open path during the communication line channel traffic to provide control power return line due to the large dynamic range.

To control the power level signalalert lines of communication of the mobile station through a closed circuit 300, BS 101 at step 301 measures the signal-to-interference (C/P) signal return line communication transmitted from the mobile station. The measured S/N compared to the installation point With a/P on the stage 302. The measured S/N can be in the form of Eb/I, which is the ratio of bit energy to interference, and therefore the installation point can be in the same form. The installation point is selected for the mobile station. The installation point may be initially based on installed capacity by using an open path through the mobile station.

If the measured C/N is greater than the installation point, at step 303, the BS 101 instructs the mobile station to reduce the power level of your signal return line connection, for example, the value of 1 dB. When the measured C/N is greater than the point of installation, it indicates that the mobile station passes through a return line connection with a signal power greater than necessary to maintain adequate communication of the reverse link. In the mobile station is instructed to reduce the power level of your signal return line to reduce the overall interference in the system. If the measured C/N is less than the installation point, at step 304, the BS 101 instructs the mobile station to increase the power level of your signal return line connection, for example, the value of 1 dB. When the measured C/N is anise, than the point of installation, it indicates that the mobile station passes through a return line connection with the power level of the signal lower than necessary to maintain adequate communication of the reverse link. By increasing the power level of the mobile station may be able to overcome the interference level and to ensure adequate communication of the reverse link.

The operations performed at steps 302-304 may be called power control using internal contour. Power control using internal contour of the support (S/P) return line connection in BS 101 as close as possible to its target threshold, which is provided with an installation point. The target ratio C/P is based on the installation point selected for the mobile station. The power increase or decrease can be executed several times within the time frame. One time frame can be divided into 16 groups power control. Each group power control consists of several data characters. The command to increase or decrease the power can be transmitted 16 times per frame. If one data frame is not received in the step 305, the circuit 300 power control continues to measure the ratio C/P signal return line for the next group power control at step 301. The process is repeated at stages 02-304 until until at least one data frame will not be received from the mobile station.

One installation point or purpose may not be satisfactory for all conditions. Therefore, the installation point used at the step 302 may also vary depending on the desired frame error rate of the reverse link. If one frame of data received in the step 305, the new WP install With a/P can be computed in step 306. New installation point becomes the new aim S/n for the mobile station. New installation point can be based on a number of factors, including the frequency of error frames. For example, if the frequency error frames above the specified level, indicating an unacceptable error rate frames, the installation point can be raised to a higher level. When you raise the point of installation to a higher level, the mobile station increases its power level on the return line through the comparison at step 302 and commands to increase power in step 304. If the frame error rate below a preset level, indicating an acceptable error rate frames, point of installation can be reduced to a lower level. When lowering the point of installation to the lower level of the mobile station in the result reduces its transmit power on the reverse of the communication line by comparing to e is up 302 and commands reduce power stage 303. The operations performed at steps 305-306, repeat in a loop from step 306 to step 303 to specify a new installation point, and repeat in a loop to step 301 for measuring C/N new frames can be considered as an open circuit. Capacity management using open path can manage once for each frame, and power control using closed loop can operate once for each group of power control. One frame and one group power control can be equal to, respectively, 20 and 1.25 MS in duration.

The system can also use the control circuit of the power of direct communication line to minimize interference. PS periodically communicates with the BS about the quality of voice and data. Measuring the frequency error of personnel and quality are reported to the BS through a report message power measurement. The message contains the number of frames received with errors in a straight line within a certain interval. The power level of the signal straight line is adjusted based on the number of error frames. Because this feedback quality measurement based on the frequency error frames, such a mode of measuring the power of a direct line of communication BS-SS is slower than the power control of the reverse link. For quick response bit erase the return line can be is used, to inform the BS, there was obtained the previous frame with error or without error. Increasing the capacity of the channel can be controlled continuously, at the same time controlling the message or bit Erasure as a way to control the power level of a straight line.

Data signal direct line of communication can be transmitted in TS with a constant power level at the same time, adjusting the effective data rate direct line of communication designed for PS. Adjusting the data transmission speed in a straight line from the point of view of the whole system is kind of interference management. Note that the capacity management direct line of communication is usually to manage interference in the service area and/or for the separation of the limited communication resources. When measuring the quality of the feedback indicates poor reception, data transmission speed can be reduced at the same time, maintaining a constant power level to overcome the effect of interference. The data rate can also be reduced to allow other mobile stations to receive the ball in a straight line with a higher speed transfer of data.

In addition to the circuits power control with open loop and closed loop, PS can adjust the output power level using the attribute code is the first channel, defined standard. PS can set the power output of the header channel enhanced access channel data accessibility and data common control channel reverse lines of communication regarding the level of the output power of the pilot channel signal of the reverse link. The output power of the pilot channel signal return line connection is established when the power control with open loop and power control using closed loop. PS to maintain the ratio of the power level between the power level of the code channel and power level of the pilot channel signal of the reverse link. Attitude can be defined using the data transfer rate used in the code channel. Typically, the table provides values for the relationship at different speeds. The ratio generally increases for higher data transmission speeds. A ratio equal to one, or the ratio is less than the unit may also be possible. When the ratio equal to one, the power level of the pilot channel signal, which is set using the circuit 300 controls a power equal to the power level of the code channel. For data trafc channel data rate and power level of the channel traffic can be regulated. The power level signal is to be selected on the basis of the relative power of the pilot signal on the reverse link. When a valid data rate is selected, the corresponding gain of the channel relative to the power level of the pilot signal return line is used to set the power level of channel traffic.

In data mode, the BS may provide the communication line in a large number of PS with different data transmission speeds. For example, one COP in the United state in a straight line can accept data with a low data rate, and the other cops can't take with high speed data transfer. On a return line connection, the BS may receive a number of signals the return line from different PS. PS on the basis of independent measurements may decide to request the required data rate from the BS. The required data transmission speed in a straight line can be transmitted to the BS through the control channel data rate (RDM). BS attempts to transmit data via a direct communication line with the required data rate. On a return line connection PS can autonomously choose the data rate of the reverse line of the range of possible data rates of the reverse link. The selected data rate can be transmitted to the BS through the channel pointer speed transmission return line. Each substation can also be limited to a specified what level of service. Level of service may limit the maximum available data rate for direct and/or reverse links. In addition, data may not be continuous in a certain sense, when, perhaps, is transmitted voice data. The receiver can receive data packets at different intervals. The interval for the other receiver may be different. For example, the receiver can receive data at random, while the other receiver can receive data packets over short time intervals.

Data transmission with high data rates requires a higher power level, signal transmission/reception than with low data rates. Direct and reverse lines of communication can be process the same data rate in the case of voice messages. Data transfer speeds forward and reverse communication lines can be limited to low data rates, because the frequency spectrum of speech information is limited. Possible speed transmission of voice data are well known and are described in standards, communication systems, multiple access, code-division multiplexing (mdcr), such as IS-95, IS-2000 and SMDR. However, for a data transmission line and a return line connection can have the same data rate. For example, PS can extract a large file the data from the database. In this case, the relationship in a straight line due mainly engaged for transmission of data packets. Data transmission speed in a straight line can reach up to 2.5 megabits per second in data transfer mode. Data transmission speed in a straight line can be based on the request data transfer rate, made with PS. On a return line connection, the data rate may be lower and may be in the range from 4.8 to 153,6 Kbps per second.

Usually in the communication system 100, in accordance with the variations in implementation, the operation cycle of the communication channel is determined, and the power level of the communication channel is controlled on the basis of a particular work cycle. Each transmission channel or communication can be in the time frame. For example, each time frame may be for the duration of 20 MS. The data rate of each time frame can be in the range from 1250 to 14400 bits per second. As such, the number of bits in each frame may be different, depending on the data rate. The channel can be used for the transmission of user and signaling information for the call between the user and the recipient. The user may use the mobile station, such as mobile stations 102-104, to call. Any of the mobile stations 102-104 may be a cell phone. The recipient can is to be the base station 101.

In accordance with the embodiment, the communication channel can be specialized managing channel (QMS). Channel BITCHES can be used for the transmission of user and signaling information to support the call data traffic between the user and the recipient, such as, respectively, the mobile stations 102-104 and the base station 101. The number of frames BITCHES transmitted within a certain period of time, may be different, depending on use. As such, the time between the transmission of a time frame FEMALES during the call traffic data may be different. For example, even if data traffic can be transmitted, the transmission frame over the communication channel, such as FEMALES, may not necessarily occur. In another situation several time frames of the communication channel, such as FEMALES, can be transmitted in a short period of time. Therefore, the duty cycle of the frame transfer communication channel, such as FEMALES, may be different at different points in time.

Test procedure for bit indicator of quality (BOD) may contain three parts, which may overlap. Various disclosed embodiments of provide a simplified procedure. The nature of changes in BOD for the dedicated control channel direct lines of communication that may be performed by a specialized Manager canaloplasty lines of communication for mobile stations, which support the configuration of a channel that does not contain the main channel of direct communication line. Power control using closed-loop trafc channel direct lines of communication in the base station will be valid during this test. When working with the regime FPC_MODE equal to '100'and the configuration of the channel, which does not contain the main channel of direct communication, the mobile station continuously monitors a dedicated control channel for direct communication line, and sends BOD. When the frame is active, bit quality indicator has the same value as the bit rate error (BPO). When the frame is not active, BOD indicates the quality of the channel. In certain tests, the process verifies that the mobile station sends BOD with the same value as the BSR for active personnel. In certain tests, the process verifies that the mobile station sends the BOD in accordance with the quality of the received signal is not active frames only with a bit power control (i.e., no data).

With speeds of 1500 or 1800 bits per second, as in the main channel of the straight line in the same test configuration of radio communication; or 2.
