Abstract
A PDMA terminal 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 can perform an adaptive array processing for each of the plurality of subarrays. A memory 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 controls a processing to transmit possible multiplicity information to another radio apparatus at a prescribed timing.
Claims6
A radio apparatus capable of communicating with another radio apparatus, the radio apparatus comprising:
- a communication unit configured to communicate using an antenna;
- a storage unit which stores beforehand a value indicating possible multiplicity associated with the number of spatial paths formable by said communication unit;
- and
- a control unit which controls a processing of transmitting the value indicating possible multiplicity to the another radio apparatus at a predetermined timing.
