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： 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 method of processing, in parallel fashion, messages from a User Equipment (UE) in soft handoff with a plurality of base stations of a wireless communication system. Measurement Messages from the User Equipment are received and stored in a message buffer for a defined period of time. Later arriving messages replace previous messages during the defined period of time. When the defined period of time elapses, the latest stored message is processed in parallel fashion in a processing pipeline with other messages for the UE and other UEs. The latest message is processed by first converting it to soft handoff actions and inserting such actions into a processing pipeline. A conflict table is generated during the parallel processing of the soft handoff actions to avoid the processing of messages that conflict with each other. Conflicting messages are put into a pending state and remain in such state until they are canceled by subsequent messages or the conflict no longer exists.
摘要翻译：一种处理与无线通信系统的多个基站进行软切换的来自用户设备（UE）的消息的并行处理方法。来自用户设备的测量消息被接收并存储在消息缓冲器中定义的时间段。后来的消息将在定义的时间段内替换以前的消息。当定义的时间段过去时，最后存储的消息在与用于UE和其他UE的其他消息的处理流水线中并行处理。首先将最新消息转换为软切换动作，并将这些动作插入到处理流水线中。在软切换动作的并行处理期间产生冲突表，以避免处理相互冲突的消息。冲突的消息将处于挂起状态，并保持在这种状态，直到它们被后续消息取消或冲突不再存在。

摘要： A method of adjusting a power level of communications over a channel in a wireless communications network. In the method, a determination (e.g., by a radio network controller (RNC)) is made regarding a number of base stations actively communicating with a mobile station. For example, the determination may indicate whether the mobile station is engaged in soft handoff or simplex mode. One of a plurality of power control algorithms (e.g., a fixed offset power control algorithm, a channel quality indicator (CQI) power control algorithm, etc.) is selected based on the determination. A power level of communications over the channel (e.g., a downlink communications channel to the mobile station) is then adjusted in accordance with the selected power control algorithm.

摘要： In a method of detecting a mobile station that is not following a power control command, for each time slot, a received signal-to-interference ratio (SIR) value of the mobile as measured by a given base station is compared with a given average SIR target value. An error metric may be generated for each slot based on a difference between the measured SIR and average SIR target values. The generated error metrics may be averaged over a given time duration to determine at least one (or more) average error value(s), and the mobile station is determined as violating a power control command if the at least one or more average error value(s) exceed a given threshold.

摘要： A wireless communication network (20) utilizes a down bias to minimize or eliminate random walk when controlling a transmit power between a base station (38) and a mobile station (40). In a disclosed example, a link quality monitoring module (54) determines the quality of a link between the mobile station (40) and the base station (38). A power control module (52) applies a down bias, which is dependent on the determined link quality, to a transmit power correction for minimizing random walk. In a disclosed example, the down bias varies linearly and inversely proportionally to the quality of the link between the mobile station and the base station.
