摘要： Disclosed is a method for improving call quality and capacity by integrating a dynamic channel allocation technique into an intelligent antenna system. The intelligent antenna systems includes beams which are grouped into sets, wherein each set has associated a long list and a primary short list, and each beam has associated a secondary short list. In one embodiment, long term interference levels are measured on each beam in a set of beams for a plurality of communication channels to produce the long list; short term interference levels are measured on each beam in the set of beams for a portion of the plurality of communication channels to produce a plurality of secondary short lists and the primary short list; and communication channels are assigned to a mobile-station from the portion of the plurality of communication channels based on the measured short term interference levels on each beam in the set of beams. The long list and the primary short list are based upon highest measured long and short term interference levels, respectively, for each of the plurality of communication channels across each beam in the set of beams.

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.

摘要： The scheduling of data transmissions for a CDMA system downlink or other type of communication network is implemented on a dynamic basis using a revenue-based policy. For a given transmission slot or other transmission interval, a maximum-rate user is identified from among a set of users requesting data transmissions, and a data transmission of the maximum-rate user is scheduled for the given interval. The maximum-rate user is identified based on application of coefficients of a revenue vector to corresponding feasible rates of the requesting users. The revenue vector is determined in an iterative manner using an adaptive algorithm which updates the revenue vector periodically to compensate for observed deviations between actual and target throughput, such that the deviations are reduced over time and the revenue vector converges to an optimal revenue vector. Advantageously, the invention allows the revenue vector to be determined without direct estimation of the frequency of occurrence of particular user rates.

摘要： An access node of a communication system comprises a plurality of transmitters adapted for communication with at least one receiver. The access node is operative to transmit pilot signals from respective associated ones of the transmitters, to estimate channel coefficients between the transmitters and the receiver, and to utilize the estimated channel coefficients to control at least one data signal sent by at least one of the transmitters. The pilot signals are partitioned into a plurality of sets of pilot signals such that pilot signals from the same set have respective subpilots that are orthogonal to one another and pilot signals from different sets have respective subpilots that are not orthogonal to one another but are instead quasi-orthogonal to one another. The pilot signals are associated with the respective transmitters based on the partitioning of the pilot signals into sets.
