摘要： A wireless communication network (20) includes a power management module (50) for controlling the power of transmission between a base station (38) and a mobile station (40). Bearer traffic (e.g., voice or data signals) are transmitted using a first transmission power limit. Handoff messages are transmitted using a second, higher transmission power limit. In one example, the power management module (50) selects an increment to the first transmission power limit for purposes of transmitting handoff signals.

摘要： A wireless communication network (20) utilizes a hard handoff procedure for switching between cells serving a mobile station (40). In a disclosed example, the existing link between the mobile station (40) and a serving base station (38) is not released until a new link between a target base station (32) and a mobile station (40) is established. At the same time, however, the mobile station maintains only one base station or link within its active set at all times. The disclosed example is useful for dedicated channel and shared channel communications in CDMA systems, for example.
摘要翻译：无线通信网络（20）利用硬切换过程来在服务于移动台（40）的小区之间切换。在公开的示例中，在建立目标基站（32）和移动站（40）之间的新链路之前，不释放移动台（40）与服务基站（38）之间的现有链路。然而，同时，移动台始终在其活动集内仅维护一个基站或链路。例如，所公开的示例对于CDMA系统中的专用信道和共享信道通信是有用的。

摘要： A method for controlling a wireless communications system is provided. A plurality of substantially identical base stations, each capable of being operated as both a primary agent and a secondary agent are deployed. The secondary agent is capable of communicating with a mobile device and the primary agent is capable of communicating with a network. A network active set associated with a mobile device is formed from a plurality of the base stations. One of the base stations in the network active set is selected to operate as the primary agent, and it communicates to the other base stations that the selected base station is operating as the primary agent. Thus, communications between the network and the mobile device are routed through the primary agent and the selected secondary agent.

摘要： The invention includes a method and apparatus for creating a base station neighbor list for a target base station in a network comprising a plurality of base stations. A method includes obtaining signal strength measurement information associated with a set of candidate base stations, creating the base station neighbor list by selecting ones of the candidate base stations for inclusion in the base station neighbor list in a manner for substantially maximizing a number of locations in the coverage area of the target base station receiving signal coverage from at least a threshold number of selected ones of the candidate base stations, and storing the base station neighbor list. The base station neighbor list may be updated periodically, or in response to changes to signal strength measurement information. The base station neighbor list is distributed from the base station to wireless user devices served by the base station for use by the wireless user devices in making handoff decisions.

摘要： Methods of reverse link power control are provided. In a first example reverse link power control process, a signal-to-interference+noise (SINR) is measured for a plurality of mobile stations. A power control adjustment is determined for each of the mobile stations based on the measured SINR for the mobile station and a fixed target SINR, the fixed target SINR being used in the determining step for each mobile station and sending the power control adjustments to the mobile stations. In a second example reverse link power control process, one or more signals are transmitted to a base station. A power control adjustment indicator indicating an adjustment to a transmission power level is received. The received power control adjustment is determined based on a measured signal-to-interference+noise ratio (SINR) for the one or more transmitted signals and a fixed target SINR threshold, the fixed target SINR threshold being used for power control adjustment of a plurality of mobile stations.

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.
