  Third generation (CDMA) mobile communication systems can efficiently provide communication services of various transmission rates (multimedia) from low speed to high speed by widening the communication bandwidth. For example, by using links (modulation method, spreading factor, etc.) of different communication formats on the uplink / downlink, the uplink / downlink communication speed can be supported asymmetrically, so that it can be seen in Internet access. Even in asymmetric communication (upstream / low speed small capacity, downstream high speed / high capacity), radio resources can be used effectively.

  In general, a mobile station connected to a base station on a one-to-one basis and a base station accommodating a plurality of mobile stations have different device configurations. However, in this embodiment, uplink / downlink information using a dedicated channel is different. In order to explain mainly the exchange, the configurations of the base station and the mobile station are shown in contrast.

  FIG. 2 is a diagram for explaining the channel transmission / reception unit according to the embodiment, and shows an example of the data channel processing units 13 and 23 in the channel transmission / reception units 10 and 20 of the base station 100. Although not shown, the same applies to the mobile station 200. The channel transmitter 10 can multiplex transmission of user data and control information and multiplex transmission of a plurality of user data by multiplexing a plurality of transport channels on a physical channel.

  The transmission channel checking unit 15 checks the data channel transmission processing unit 13 using the free time of the data channel transmission processing unit 13 during communication. This test is preferably performed by dividing the data channel transmission processing unit 13 into a plurality of blocks by function and inputting a fault test pattern corresponding to each function, and preparing an output test result (circuit processing result) in advance. By comparing with the pattern of the correct processing result, the presence / absence of a circuit failure is determined based on the presence / absence of matching. Such an inspection may be performed sequentially for each functional block of the selected empty individual channel, or may be performed simultaneously (parallel) for each block. In any case, since the inspection per block is relatively simple, even if the entire data channel transmission processing unit 13 is complicated, it is possible to easily inspect and specify the presence or absence of a detailed failure in a short time. The same applies to the reception channel inspection unit 25.

  FIG. 3 shows an outline of various radio frame formats according to the embodiment. This figure shows the control channel (B in the figure) time-multiplexed on the slot-divided data channel or the control channel (in the figure) transferred in parallel with the data channel, which is the scope of application of the present invention. This is for explaining a more general concept of performing a data signal reception process according to the control information mounted in A), and does not necessarily indicate a specific example based on the W-CDMA system. Therefore, it is applicable to both base stations and mobile stations.

  FIG. 3A shows a case where one or more data channels are transmitted in parallel with the control channel. The number of data channels in this example is set by call control when a call is connected between the base station and the mobile station. In the line, synchronous detection is maintained by pilot symbols of the control channel, and power control is performed by signals in the power control field. The “data size” represents the size of data mounted on the data channel of the slot. When the size is “0”, the data channel is free time. Even when the data size is not “0”, the processing time of the data channel varies depending on the “modulation method”, the “coding rate”, and the like, and can be used as a reference for obtaining the free time of the data channel. Note that, as in the W-CDMA system, there may be a control channel and a data channel for each individual channel.

  FIG. 3B shows a case where data signal reception processing is performed according to control information of the control channel CCH time-multiplexed with the data channel DCH. The usage of each channel may be the same as that described in FIG.

FIG. 4 is a diagram showing a frame configuration of the dedicated physical channel DPCH in the W-CDMA system, and shows one more specific application example of the present invention. (A) in the figure shows the uplink frame format from the mobile station to the base station, and (B) in the figure shows the downlink frame format from the base station to the mobile station. The radio frame (10 ms) of the physical channel is divided into 15 time slots. The dedicated physical channel (DPCH) includes a data channel DPDCH that transmits user information and a control channel that transmits control information. In the uplink, the data transmission rate of the control channel DPCCH is constant (15 kbps) and is spread with a fixed spreading factor (SF = 256). On the other hand, the data transmission rate and spreading factor of the data channel DPDCH vary depending on the amount of information. When the number of information bits per slot is 10 × 2 ^k (k = 0 to 6), the spreading factor is 256/2 ^k corresponding to the number of information bits. Therefore, the data transmission rate is 15 kbps to 960 kbps, and the corresponding spreading factor is 256 to 4.

Thus, since the uplink control channel and data channel are transmitted at different transmission rates (ie, independent), DPDCH and DPCCH are modulated by BPSK and multiplexed on the I and Q axes, respectively. Therefore, even when there is no transmission information on the DPDCH, the transmission is not interrupted by continuously transmitting the control information of the DPCCH. In the present embodiment, the data channel DPCCH is inspected using this idle time. On the other hand, in the downlink, information on the control channel and the data channel is time-division multiplexed, which is QPSK modulated and transmitted.

  Further, when the contents of signals exchanged in the channel are outlined, the pilot bit “Pilot” is used for maintaining the synchronous detection of the receiving unit and checking the amplitude variation of the received signal. In the present embodiment, the reception quality (SINR) of the DPCCH is detected, it is determined that normal reception is not possible because it is below a predetermined level, and the data channel DCDCH is inspected using the idle time. TFCI (Transport Format Combination Indicator) is information indicating the number of transport channels multiplexed on the DPDCH of the received frame, the format format of each transport channel, and the like. If such control information is not properly decoded, the data channel DPDCH cannot be correctly received. Therefore, in this embodiment, the data channel processing unit is inspected when a reception error of the control channel DPCCH is detected. Further, a control signal (FBI: Feedback Information) is a signal for feedback transmission from the mobile station to the base station for transmission diversity of the base station, and a transmission power control signal (TPC: Transmit Power Control) is for transmission power control. Signal.

First, in this type of base station or mobile station, when a reception error regarding the control channel DPCCH is detected due to circuit failure or fading during communication, reception of the data channel DPDCH to be performed according to the information of the control channel Processing cannot be performed properly.

Therefore, the wireless data communication apparatus can be efficiently inspected by effectively using the idle time and the idle circuit during the wireless communication.

  Also, in this type of base station and mobile station, even when there is no transmission data to be transmitted (slot), the wireless communication line (synchronous control by pilot, transmission power control, etc.) is properly transmitted by continuously transmitting the control channel. However, the occurrence of a slot that does not transmit data does not effectively use radio resources. Therefore, in the present embodiment (2), the data channel reception processing unit is inspected by effectively using the time when the data channel reception processing is unnecessary. Therefore, the wireless data communication apparatus can be efficiently inspected by effectively using the idle time and the idle circuit during the wireless communication.

  Further, in this type of base station or mobile station, when the reception quality of the control channel DPCCH is lower than required, it is not possible to properly receive the data channel received in parallel or the data channel subsequently received. Therefore, in the present embodiment (3), the reception processing time for the data channel is inspected using the reception free time of the data channel. Therefore, it is possible to efficiently inspect the data communication apparatus that is communicating.

Therefore, even if it is a data channel transmission / reception processing unit having a complicated function and configuration as a whole, the data channel transmission / reception processing unit is divided into a plurality of blocks of a size corresponding to the function and configuration, and the details are checked. The presence or absence of a failure can be efficiently separated in a short time by a relatively simple method.

  Further, in the base station or mobile station of the present embodiment (6), the call control unit 26/46 allocates a number of transmission / reception dedicated channels according to the amount of communication traffic at the time of call connection, and transmits / receives. The channel checking unit checks the remaining transmission / reception dedicated channel processing unit according to the allocated number of channels using the transmission / reception processing time of the dedicated channel. Therefore, the remaining transmission / reception dedicated channel processing unit can be efficiently inspected using the dedicated channel transmission / reception idle time.

Moreover, maintenance can be performed without stopping the operation of the apparatus by hot-swapping the dedicated channel transmission / reception processing unit in which an abnormality has been detected.
