Abstract
A network apparatus comprises a controller to determine a first base station for transmitting data and to determine a second different base station for receiving data. In one embodiment, the network apparatus further comprises a transceiver to transmit data to the first base station while associated with the second base station. The transceiver is operable to receive data from the second base station while associated with the first base station.
Claims17
A mobile station comprising:
- a controller to determine a first base station to associate with for transmitting data, wherein the first base station is selected based at least in part on a minimum uplink transmit power metric, and to determine a second different base station to associate with for receiving data, wherein the second base station is selected based at least in part on a maximum downlink SINR metric;
- and
- a transceiver to transmit data to the first base station for uplink transmissions while associated with the first base station and the second base station and while an uplink power metric is lower for the first base station than for the second base station, and to receive data from the second base station for downlink transmissions while associated with the first base station and the second base station and while a downlink capacity metric is higher for the second base station than for the first base station;
- wherein the mobile station is capable to be associated simultaneously with the first base station for uplink transmissions but not downlink transmissions and the second base station for downlink transmissions but not uplink transmissions.

A method comprising:
- selecting, based at least in part on a SINR measure, a first base station among a first plurality of base stations for receiving data, wherein the base station having a maximum SINR value for downlink transmissions is selected as the first base station from which to receive data in the downlink;
- selecting, based at least in part on a transmit power measure, a second base station among the first plurality of base stations for transmitting data, wherein the base station having a minimum uplink transmission power is selected as the second base station to which to transmit data in the uplink;
- associating with the first base station for the downlink but not for the uplink while the maximum SINR value for downlink transmissions is higher for the first base station than for the second base station;
- associating with the second base station for the uplink but not for the downlink while the transmit power measure for the second base station is lower for the second base station than for the first base station;
- and
- transmitting data to the second base station in the uplink while associated with the first base station, and receiving data from the first base station in the downlink while associated with the second base station.
3 more elements
A method comprising:
- determining a first base station to transmit data over an uplink channel based on a first criterion, wherein the first criterion is based at least in part in a minimum uplink transmission power value;
- determining a second base station to receive data over a downlink channel based on a second criterion that is different from the first criterion, wherein the second criterion is based at least in part on a maximum downlink SINR value;
- transmitting data to the first base station over the uplink channel without being associated with the first base station for the downlink channel while the minimum uplink transmission power value is lower for the first base station than for the second base station;
- and
- receiving data from the second base station over the downlink channel without being associated with the second base station for the uplink channel while the maximum downlink SINR value is higher for the second base station than the first base station.
