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.

摘要： A method of fast predictive automatic gain control is disclosed including estimating channel gain applied to a received signal, predicting channel gain at a subsequent time by applying temporal correlation statistics to the estimated channel gain, determining a predicted receiver gain which reduces variance between the predicted channel gain and a predetermined target power level, and applying the predicted receiver gain to the received signal. The method may include applying linear minimum mean-squared error prediction to the estimated channel gain. The method may include predicting error variance at the subsequent time by applying the temporal correlation statistics to the estimated channel gain and combining the predicted channel gain and the predicted error variance. The method may include estimating channel gain of known pilot symbols, estimating a temporal correlation function using the estimated channel gain, and determining predicted channel gain using the estimated channel gain and the estimated temporal correlation function.

摘要： Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.
