METHOD OF SPACE DIVISION MULTIPLE ACCESS COMMUNICATION USING USER COOPERATION AND SYSTEM OF ENABLING THE METHOD
First Claim
1. A base station comprising:
- a pilot generation unit to generate a pilot signal for transmission to a plurality of member terminals within a designated group;
a selection information-reception unit to receive, from a predetermined head node determined in advance with respect to the same group, selection information associated with a radio channel formed between at least one active member terminal and the base station when the head node selects the at least one active member terminal from the plurality of member terminals; and
a source signal generation unit to perform beam-forming of a data stream based on the selection information to thereby generate a source signal.

Abstract
A communication device using user cooperation is provided with a channel information reception unit to receive channel information from a plurality of member terminals within the same group, the channel information being associated with a radio channel formed between the plurality of member terminals and a base station; a member terminal selection unit to select at least one active member terminal from among the plurality of member terminals based on the channel information; and a selection information transmission unit to transmit selection information to the base station, the selection information being associated with a radio channel formed between the at least one active member terminal and the base station.
