    摘要: A receiver device for use in a wireless communication system (20) includes a rake receiver (32) and an equalizer receiver (34). A controller (36) selects one of the rake receiver (32) or the equalizer receiver (34) for processing a received signal. In some situations, the rake receiver (32) will provide better performance. In other situations, the equalizer receiver (34) will provide better performance. One embodiment includes a plurality of equalizers (34A, 34B). One of the equalizers processes a data packet from a received signal while another one of the equalizers trains for processing a signal from a subsequent scheduled user. Another example embodiment includes controlling an equalizer length based on a delay span or another selected channel metric.

    摘要: In a method of tracking on-time errors in a wireless communication system, first and second metrics may be produced from accumulated signal samples of a received data frame, and a sum of, and a difference between, the first and second metrics may be calculated. The calculated difference and sum values may be used to determine an estimated on-time error for the received data frame and a corrected timing error control value to be applied to the on-time error. The accuracy of the estimated on-time error may be evaluated based a signal quality metric to determine whether the corrected timing error control value is to be applied to the estimated on-time error or whether the timing adjustment for the on-time error is to be stopped.

    摘要: A method of calculating a power threshold for a secondary communication channel capable of operating in DTX mode in forward or reverse links so that the communication channel is prevented from entering a deadlock state. Power threshold information for an associated primary channel and the secondary channel are used to update the established power threshold for the communication channel. The updated power threshold for the communication is thus calculated by combining previously established thresholds for the communication channel and associated primary channel with a current established threshold for the associated primary channel.

    摘要: In one embodiment of the method, a channel quality metric for a first subframe is estimated based at least in part on a channel quality metric for a previous subframe, and a channel quality metric for a second subframe is estimated based at least in part on the channel quality metric for the previous subframe. Here, the second subframe is later in time than the first subframe. Then, a channel quality metric for a time slot located between the first and second subframes is estimated based on the channel quality metrics for the first and second subframes.

    摘要: We disclose a method of dynamic channel assignment for wireless transmission systems that employ time or frequency multiplexing, or both time and frequency multiplexing. The invention is specifically addressed to the problem of avoiding interference in the channels of such systems. In a broad aspect, the invention involves partitioning base stations of a network into non-interfering sets. Channels are allocated to the non-interfering sets according to need. Stages of channel reallocation take place periodically. The reallocation takes place through coordinated activity by the base stations. That is, the channel reallocation is carried out in response to information that is exchanged between base stations, or it is centrally directed by the network in response to information passed to the network by the base stations.
