Radio apparatus, and method and program for controlling spatial path

摘要

A PDMA terminal (1000) establishes communication by forming a plurality of spatial paths to another single radio apparatus. A plurality of antennas constituting an array antenna are divided into a plurality of subarrays corresponding to the plurality of spatial paths respectively. An adaptive array processing unit (USP) can perform an adaptive array processing for each of the plurality of subarrays. A memory (MMU) stores in advance information on the number of antennas associated with the number of spatial paths that can be formed by the array antenna. A control unit (CNP) controls a processing to transmit possible multiplicity information to another radio apparatus at a prescribed timing.

主权项

1. A radio apparatus for communication by forming a plurality of spatial signals to another radio apparatus, comprising:
a plurality of transmission units connectable to a plurality of antennas; at least a signal processing unit capable of processing spatial signals to be transmitted through the plurality of transmission units and the plurality of antennas; storage means for storing in advance information on the number of spatial signals that can be processed by the signal processing unit, wherein the number of spatial signals is smaller than or equal to the total number of the plurality of antennas; control means for controlling a process of transmitting the information on the number of spatial signals.
