Mobile communication apparatus and method including base station and mobile station having multi-antenna
First Claim
1. A mobile communication apparatus with multiple base station/mobile station antennas, the apparatus including a base station and at least two mobile stations, comprising:
- the base station restoring weight information and channel status information from feedback signals received from the mobile stations, determining downlink investigation information that results in maximum transmission channel capacity based on the restored weight information and channel status information, selecting mobile stations for simultaneous transmission from among all of the mobile stations based on the downlink investigation information, and processing data to be transmitted to the selected mobile stations based on the downlink investigation information, wherein the base station includes at least two base station antennas and each of the mobile stations includes at least one mobile station antenna.

Abstract
The present invention discloses a mobile communication apparatus and method including a base station and a mobile station both having multi-antenna. As for the apparatus, including a base station and at least two mobile stations. The base station carries out the following functions: (a) restores weightied information and channel status information which have been decided by mobile stations from feedback signals received by mobile stations; (b) selects the downlink detect information which satisfies the largest transferring channel capacity from the above weighting information and channel status information which have been restored; (c) selects mobile stations to transmit at the same time from all mobile stations which are able to transmit using downlink detect information; and (d) processes data which will be transferred to select mobile stations with downlink detect information. The base station has at least one base station antenna, and the mobile station has at least one mobile station antenna.
