摘要： A method for locating a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises associating the mobile device with a first base station of the plurality of base stations. Thereafter, a paging signal is delivered from a subset of base stations associated with the first base station to the mobile device. The subset of base stations may correspond to a network active set of base stations associated with the mobile device. Thereafter, when a signal from one of the base stations in the subset of base stations is received, indicating that the mobile device responded to the paging signal from the one base station, then the mobile device is located and may be associated with the one base station for future paging attempts.

摘要： Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.

摘要： A method for controlling a communications session with a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises selecting a plurality of base stations, where at least a portion of the base stations are adapted to operate as a secondary agent, and wherein the secondary agent is capable of communicating with a mobile device. Substantially similar control information regarding the communications session is maintained in a plurality of the secondary agents. A first one of the secondary agents is selected as a first serving secondary agent to communicate with the mobile device. The first serving secondary agent uses the control information during the communications session with the mobile device. In this manner, each of the secondary agents is capable of quickly and efficiently taking over the role of communicating with the mobile device.

摘要： Without intercell coordination on a per communication request basis, channel assignment can be efficiently performed by developing for each cell, or a sector thereof when the cells are sectorized using directional antennas, a priority list of groups of channels, and selecting a channel to be assigned in response to a request for service from the highest priority group which has available channels at the time of the service request. The priority lists are developed based on various interference measurements that are made. The priority lists tend to remain the same for relatively long periods of time. However, periodically, the priority lists should be redetermined to insure that the best lists are being employed. For example the lists may need to be changed due to new construction or to seasonal vegetation changes which may affect the interference experienced in the system. Advantageously, system capacity under peak concentrated load conditions may increase. This advantage is further magnified under field conditions for which the cell shapes are not ideal.
