    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： 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： A method of scheduling and sub-channelization is provided for a wireless network such as an OFDMA network. Distributed coordination is applied across sectors, such neighboring sectors will tend to schedule cell-edge users at the same time, while sub-channelizing to different portions of the full frequency band available for forward link transmissions. This tendency is achieved by dividing each sector's users into user classes which depend upon forward link channel quality. Each user class is assigned a different set of priorities for use of available timeslots and subcarriers.

    摘要： Methods of reverse link power control are provided. A first example method includes first measuring a first type of interference, second measuring a second type of interference, determining a ratio between the first and second measurements and broadcasting the determined ratio to a plurality of mobile units. A second example method includes receiving a broadcasted ratio indicating a ratio between two different types of interference and calculating a power level for reverse link transmissions based on the received broadcasted ratio. A third example method includes first adjusting OFDMA transmission power based on first feedback signals during an OFDMA transmission and second adjusting OFDMA transmission power based on second feedback signals during periods between OFDMA transmissions. A fourth example method includes receiving a plurality of interference indicating signals from different base stations and determining whether to adjust a maximum transmit power threshold based on the plurality of interference indicating signals, the maximum transmit power threshold indicating the maximum permitted transmission power level below which transmissions are constrained.
