- the signal received by the antenna # 1 is subjected to predetermined radio processing such as down-compression by the reception processing unit 101-1-1, and then held in the buffer 102-1.
- the signal received by the antenna # 2 is subjected to predetermined radio processing such as down-computing by the reception processing unit 101-2, and then held in the buffer 102-2.
- the antenna # 2, the reception processing unit 101-2, and the buffer 102-2 are dedicated to diversity reception of HSPA (High Speed Downlink Packet Access).
- HSPA High Speed Downlink Packet Access
- the mobile station device equipped with the wireless receiving device of FIG. 1 is currently located in a cell that provides the HSPDA service (HSPDA serving cell). Therefore, both the signal received by antenna # 1 and the signal received by antenna # 2 include the HSPDA serving cell signal (HSPDA signal).
- the II SDPA signal includes HS-SCCH (Hi Speed-Shared Control Channel) signal, HS-PDSCH (Hi Speed-Physical Downlink Shared Channel) signal, CPICH (Common Pilot Channel)
- the switching of the switch 103 is controlled by the control unit 104, and the received signal held in the buffer 102-1 or the buffer 102-2 is despread by the despreading unit 105 and the despreading unit 10. Enter 8 The switching control will be described later.
- the despreading unit 105 performs despreading on the received signal input and obtains the despread result.
- delay PF profile
- Delay PF creating section 106 creates a delay profile from the result of despreading and inputs the result to path detecting section 107.
- Path detector 1 0 7 detects a path which is a predetermined threshold or more levels from the delay profile, Note c inputs a signal indicating a path located in despreader 1 0 8, despreader 1 0 5.
- the synchronous processing unit is composed of the delay PF creating unit 106 and the path detecting unit 107.
- the despreading unit 108 is provided with the number of receivable paths, and performs despreading on the input received signal in accordance with the timing of the path position detected by the path detection unit 107.
- the signals of the respective paths after despreading are R AKE synthesized by the R AKE synthesis unit 109.
- the signal after RAKE synthesis is error-correction decoded by decoding section 110, and as a result, received data is obtained.
- a synchronization processing unit (a despreading unit 105, a delay PF creating unit 106 and a path detecting unit 107) is provided for only one branch.
- the synchronization processing unit performs synchronization processing for two branches. By operating the synchronization processing unit in a time-division manner, it is possible to process received signals for a plurality of cells.
- the synchronization processing unit repeats a series of synchronization processing at a predetermined cycle (two frames in Figs. 2 and 3).
- the control unit 104 determines that there is no free resource in the synchronization processing unit.
- the switch 103 is kept connected to the buffer 102-1 and the despreading unit 105. Then, after the despreading of N cells and creation of the delay profile are completed, path detection is performed. Therefore, in this case, since the synchronization processing is performed only on the signal received by antenna # 1, diversity reception is not performed. In other words, the total number of cells connected at the same time If N has reached N and there are no free resources in the synchronization processing unit, diversity reception is not performed.
- the control unit 104 determines that the resources of the synchronization processing unit are free. After completing the despreading and delay profile creation for the simultaneously connected cells performed on the received signal of antenna # 1, switch switch 103 is switched over, and The despreading unit 105 is connected. Thereby, the received signal held in buffer 102-2 is input to despreading section 105. Since the antenna # 2, the reception processing unit 101--2, and the buffer 102--2 are provided exclusively for the HSDPA serving cell, the switching control allows the reception of the antenna # 2 by the antenna # 2.

- the despreading and the creation of the delay profile are performed on the CPICH signal and the DPCH signal among the HSPDA signals.
- path detection is performed based on the delay profile for the received signal of antenna # 1 and the delay profile for the HSPDA signal of antenna # 2. In other words, if the total number of simultaneously connected cells does not reach N, diversity reception is performed on the HSDA serving cell using the available resources. Also, since the number of HSPDA serving cells is limited to one cell for the mobile station apparatus, the total time of the synchronization processing for antenna # 1 and antenna # 2 is N cells or less shown in FIG.
- Path detection in the path detection unit 107 is performed as follows. First, the path detection unit 107 sets a delay profile created by the delay PF creation unit 106 for each cell to a path having a level equal to or higher than a predetermined threshold as a finger assignment candidate path for each cell. To detect. Then, among the detected paths, a predetermined number of paths are assigned to the fingers for each cell. At this time, the value of the delay profile is large A predetermined number is assigned in order from the object. This predetermined number is set to a different value for each cell. For example, a predetermined number N is set for cells other than the HSDPA serving cell, and a predetermined number N-HS larger than the predetermined number N is set for the HSDPA serving cell (N-N-HS).
- a predetermined number N-HS-div larger than the predetermined number N_HS is set for the HSDPA serving cell (N-N-HS ⁇ N-HS-div).
- the delay port file for antenna # 1 and the delay profile for antenna # 2 are collectively assigned to the fingers, and paths up to a predetermined number N-HS-div are assigned to the fingers.
- the number of paths with good reception quality, which are candidates for finger assignment relatively increases according to the number of antennas. By setting the number to be larger than the predetermined number, it is possible to perform finger assignment effectively using diversity reception, and to improve reception characteristics.
- reception processing for antenna # 2 may be stopped. That is, the operations of the reception processing unit 101-2 and the buffer 102-2 may be stopped. By stopping reception processing for antenna # 2 when diversity reception is not performed, power consumption can be reduced.

Entered in 17.
- the gain control unit 1 17 measures the received power of the signal received by the antenna # 1 and the received power of the signal received by the antenna # 2, compares them, selects the higher received power, and selects the selected received power. Based on the received power, the gain value of AGC (Automatic Gain Control) performed by the reception processing units 101-1 and 101-2 is calculated. Then, the obtained gain value is input to both the reception processing unit 101-1 and the reception processing unit 101-2.

The control unit 118 notifies the control unit 118 of the signal received by the antenna # 2 (the received signal held in the buffer 102-2). Control section 118 selects a received signal having the larger received power according to the selection result notified from gain control section 117 and inputs the received signal to cell search section 120. In other words, when the received power of the signal received by antenna # 1 is greater, control section 118 connects buffer 102-1 to cell search section 120 by switch 119. Conversely, if the received power of the signal received by antenna # 2 is higher, switcher 119 connects cell buffer 102 to cell search section 120. Cell search section 120 performs a cell search based on the input received signal and outputs a cell search result.
- AGC of antenna # 1 and antenna # 2 constituting diversity reception are performed based on the same gain value, and AGC of antenna # 1 and antenna # 2 are commonly performed. Therefore, it is necessary to consider the difference in the reception level between antennas in the path detection, RAKE combining, etc. following the reception processing including AGC in the reception processing units 101 and 101 and 101-2. Disappears. Therefore, since it is possible to adopt a configuration that does not depend on whether or not diversity reception is performed in the connected cell, it is possible to simplify the device configuration of the wireless reception device.
- the cell search is performed according to the selection result in gain control section 117 as described above, so that the device configuration can be reduced without increasing the device configuration according to the number of antennas. The diversity gain can be obtained.
- AGC is performed independently for each antenna based on the reception power of antenna # 1 and antenna # 2.

- the number of despreading sections 114 for DP CH signals and the number of despreading sections 115 for SCCP CH signals need not be the same. This is because the DPCH signal is basically transmitted from all cells communicating at the same time, so there are many path candidates for the DPCH signal, whereas the MBCCP SCCP CH signal is transmitted from one or a small number of cells. Since only the SCCP CH signal is transmitted, there are few path candidates. Because there is.
