摘要： A technique for performing channel tracking and/or channel estimation in a wireless communication device includes receiving a reference signal and one or more non-error propagation physical channel signals. In general, the one or more non-error propagation physical channel signals must be correctly decoded before a data channel can be decoded. Channel tracking and/or channel estimation are/is then performed based on the reference signal and at least one of the one or more non-error propagation physical channel signals.

摘要： A technique of operating a wireless communication system includes determining respective geometries of multiple subscriber stations, which include a first subscriber station and a second subscriber station, with respect to a serving base station. Respective control channels, which include a first control channel associated with the first subscriber station and a second control channel associated with the second subscriber station, for the multiple subscriber stations are then scheduled based on the respective geometries. The first control channel is scheduled to be encountered earlier in a control channel search procedure, of the one or more control channel symbols, than the second control channel. The first subscriber station has a lower geometry than the second subscriber station.
