Description

  The present invention relates to a wireless communication apparatus that performs reception or transmission processing in a mobile communication system, and more particularly to a wireless communication apparatus that can flexibly change signal processing dynamically.

  In recent years, there has been a great demand from the viewpoint of cost and convenience that users of wireless services want to use multiple wireless services with one wireless terminal according to the new and old wireless systems, communication charges, communication quality, and service contents. . If multiple wireless services are to be used on the same terminal, the wireless system differs for each wireless service. Therefore, digital signal processing corresponding to each wireless system is prepared for the wireless terminal, and the wireless terminal supports the wireless service. Digital signal processing means must be prepared in advance for the number of systems. If this is to be processed by a computer with a built-in program that can easily rewrite the instruction information stored in the storage device, there is a limit in processing speed because sequential processing is performed.

  On the other hand, if hardware is used that can speed up signal processing by parallel processing, hardware circuits must be arranged and wired in advance for the corresponding number of wireless systems, which increases the circuit scale and makes it wireless. There is a demerit that the volume of the terminal increases. For example, if FPGA (Field Program Gate Array) which is a gate array whose hardware configuration can be dynamically changed is adopted as means for solving the above-mentioned problems, circuit arrangement and wiring data are downloaded from a server according to a wireless system. Alternatively, the circuit configuration can be changed by reading from the storage device. However, since it takes time to configure the FPGA when switching the circuit configuration, it is difficult to smoothly switch between wireless systems.

  As means for solving these problems, there is a conventional technique capable of smoothly switching digital signal processing according to a desired wireless system without changing the physical architecture even when the wireless system is switched ( For example, see Patent Document 1).

  Referring to FIG. 1, a conventional configuration will be described. The application-specific functional unit 120 is optimized for a desired task, and a structurally programmable bridge 150 is provided for connecting the functional units. These functional units can execute processing such as filtering, demodulation, and error correction. The structurally programmable bridge includes a storage device that stores a connection procedure between functional units, and connects the functional units to each other so that simultaneous transmission is possible.

  The conventional technique having such a configuration operates by controlling the flow of data between the functional units via a structurally programmable bridge according to the data flow procedure between the functional units stored in the storage device.

If the data flow procedure between the functional units stored in the storage device is changed when the wireless method is switched, the wireless method can be changed smoothly.
Special table 2004-506989 gazette

  However, the conventional technique for changing the data flow according to the wireless system as in Patent Document 1 has the following problems.

  The first problem is that the data flow can be changed according to the radio system, but the data flow between the functional units according to the signal processing result cannot be dynamically controlled in units of radio frames. For example, the reception quality varies with time in a fading environment in a multiple radio wave propagation path, and it is impossible to flexibly change the data flow according to the variation in reception quality. The reason is that there is no means for reflecting the signal processing result in the functional unit in the data flow control between the functional units.

  The second problem is that there is not enough means for exchanging data other than the main signal between the functional units. For example, in the case of a wireless receiver that performs transmission path estimation using a known pilot channel between transceivers, it is necessary to apply a channel estimation value obtained from the pilot channel to the corresponding data channel in units of radio frames. In order to cause the wireless device of Patent Document 1 to process such an operation, a method using a storage device can be considered. Specifically, the channel estimation value obtained by a certain functional unit is stored in the storage device, and when the data channel is channel-corrected, the channel estimation value of the radio frame corresponding to the data channel is read from the storage device, Alternatively, a procedure that employs a queuing mechanism in which a channel estimation value and a data channel are paired is required. Assuming a wireless system in which the data flow is complex and data other than the main signal is frequently exchanged between the functional units, data transmission control other than the main signal across the functional units becomes complicated, and writing to and reading from the storage device is difficult. Since it occurs frequently, it may induce a decrease in throughput. This is because data other than the main signal is transmitted via the storage device.

  The third problem is that as the number of functional units increases, the circuit scale of the structurally programmable bridge that interconnects the functional units increases, and the performance of the bridge affects the overall performance of the system. . The reason is that as the number of functional units increases, the number of bridge input / output ports and the amount of processing increase, and the number of switch combinations increases exponentially.

  Accordingly, a first object of the present invention is to enable flexible control of data flow according to the result of signal processing, particularly in a wireless communication apparatus that changes data flow according to a wireless system without changing the system architecture. Is to provide a wireless communication device.

  A second object of the present invention is a wireless communication apparatus that changes a data flow according to a wireless system without changing a system architecture, and particularly a high-speed wireless system configured with a plurality of channels and acting between channels. To provide a low-cost wireless communication device.

  A third object of the present invention is to provide a wireless communication apparatus that changes a data flow in accordance with a wireless system without changing the system architecture. In particular, even if the number of functional units (signal processing units) increases, the circuit scale can be increased. To provide a wireless communication apparatus that suppresses enlargement and performs efficient signal processing.

  In order to solve the first problem of the present invention, it includes route information indicating the data flow procedure of the signal processing unit, an operation procedure indicating the content of the operation in the signal processing unit, and a route pointer indicating how far the signal processing has progressed. Means for adding an operation header (420 in FIG. 4) to processing data (430 in FIG. 4) to form a frame (231 in FIG. 2), means for connecting each signal processing unit (216 and 226 in FIG. 2), In each signal processing unit, processing according to the operation procedure and means for transmitting a frame to the subsequent signal processing unit according to the route information (360 in FIG. 3) and means for changing the operation header according to the signal processing result (in FIG. 3) 350). By adopting such a configuration, it is possible to change the operation content and control the path in units of radio frames according to the result of signal processing, thereby achieving the first object of the present invention.

  In order to solve the second problem of the present invention, the data to be processed and the processing result of the signal processing unit are stored and integrated in the transmission information (425 in FIG. 4) of the operation header, and the signal processing unit in the subsequent stage performs the integration. Means capable of referring to the transmission information are provided. By adopting such a configuration, the second object of the present invention can be achieved without using a storage device or a waiting mechanism when data is exchanged between channels.

  In order to solve the third problem of the present invention, a plurality of signal processing units are grouped by a bridge (250, 251, 252 in FIG. 2). Adopting such a configuration, it is not necessary to consider connection and data transmission with all signal processing units, and transmission / reception of frames within a group does not affect transmission / reception of frames of other groups. The third object can be achieved.

  The first effect of the present invention is that the data flow can be flexibly changed according to the processing result in the signal processing unit. As a result, it is possible to realize a wireless communication apparatus that can dynamically control the data processing procedure in the subsequent stage according to the reception quality and can perform parallel processing. For example, when the reception quality has reached a certain quality, the number of processing stages in the subsequent stage is reduced. The present invention can be applied to a system in which power consumption is reduced by thinning. The reason is that the route information such as all route information and route pointer of the signal processing unit is added to the data to be processed and controlled in units of radio frames, and the route selection means according to the route information in the signal processing unit. It is because it has.

  The second effect is that data can be easily exchanged between channels in the case of a wireless system having a plurality of channels. As a result, it is possible to process a wireless method for performing channel estimation at high speed, eliminating the need for storage devices and transmission means for exchanging data between channels, and reducing the circuit scale and the cost of wireless terminals. can get. The reason is that the processing result of the signal processing unit is added to the data to be processed as transmission information, integrated so that it can be referred to by the signal processing unit at the subsequent stage, and smooth transmission of information between channels is possible. Because it has achieved.

  A third effect is that the processing amount of the bridge connecting the signal processing units can be reduced. As a result, efficient data transmission between the signal processing units can be performed, and the effects of reducing the circuit scale and increasing the processing speed can be obtained. The reason is that it is possible to group a plurality of signal processing units and to transmit and receive data independently between the groups without affecting the access of the frames in the group to other groups.
