Abstract: 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.

Abstract: Methods and corresponding systems for allocating resources in a communications system includes determining feasible sets of subchannels for allocation to a user subject to an allocation constraint. In one approach, a constraint matrix representing constraints for allocating subchannels to users in allocations of selected subchannels is computed, subject to the allocation constraint. Then a vector containing metrics corresponding to allocations of selected subchannels to the communication links is estimated. A binary decision vector representing an allocation of the subchannels to the users is computed using binary integer processing. In another approach a greedy heuristic allocation is used. The allocation constraint can be a restriction limiting multiple subchannels allocated to a user to be adjacent to one another. The metrics can be weighted capacities of allocations of selected subchannels to the users.

Abstract: In a wireless communication system (200), a compact control signaling scheme is provided for signaling the selected retransmission mode and codeword identifier for a codeword retransmission when one of a plurality of codewords (CW1, CW2) being transmitted over two codeword pipes to a receiver (201.i) fails the transmission and when the base station/transmitter (210) switches from a higher order channel rank (231) to a lower order channel rank (241), either by including one or more additional signaling bits in the control signal (240) to identify the retransmitted codeword, or by re-using existing control signal information in a way that can be recognized by the subscriber station/receiver to identify the retransmitted codeword. With the compact control signal, the receiver (201.i) is able to determine which codeword is being retransmitted and to determine the corresponding time-frequency resource allocation for the retransmitted codeword.

Abstract: Embodiments of a system and methodology are disclosed for enabling a network to manage threshold values provided to UEs for use in decoding ACK-NAK signals. In various embodiments described herein, a base station signals an actual fixed threshold value in a semi-static manner for use by UEs to decode ACK/NAK signals. In these embodiments, the threshold value is part of a semi-static but UE-specific threshold value. This allows the base station to accommodate varying UE geometries, and optimize power savings for ACK-NAK transmissions. Embodiments of the invention also allow the base station to enforce a desired quality of service (QoS) without excessive power variations across ACK/NAK which are limited by the transmit power dynamic range.
