Abstract
On receiving a link channel assignment request or a link channel reassignment request from a mobile station, a wireless base station specifies a unique word (UW) that is not assigned to any other mobile stations, and sends a channel assignment notification containing the specified UW to the requesting mobile station. The base station also sends the specified UW to its user processing unit, which extracts a signal sent from the requesting mobile station and generates a signal to be sent to this mobile station. The base station then defines a reference signal based on the sent UW, and adjusts each weight vector by using the defined reference signal and a signal estimated to have been sent from the requesting mobile station, thereby directing the directivity pattern to the requesting mobile station.
Claims7
A wireless base station that wirelessly communicates with a plurality of mobile stations by using space division multiplexing (SDM), each mobile station sending communication data containing an identifier (ID) to the wireless base station, comprising:
- association information storing means for storing association information that associates each of the plurality of mobile stations with a different ID;
- receiving means for receiving data into which communication data sent from the plurality of mobile stations is space-division multiplexed;
- and
- extracting means for (a) specifying an ID associated with each mobile station by referring to the association information, and (b) extracting, from the received data, communication data sent from the mobile station by using the specified ID.
A wireless phone, comprising:
- receiving means for receiving an identifier (ID) sent from a wireless base station;
- and
- sending means for sending communication data containing the received ID to the wireless base station.
