摘要： A base station generates per-cell ACK/NACK responses rather than per-sector ACK/NACK responses. For a given mobile station signal received in softer handoff at two of the base station's sectors, the base station generates an ACK response if at least one of the soft handoff sectors correctly receives the signal, and otherwise generates a NACK response. Alternatively, the base station can combine the softer handoff signals and generate ACK/NACK responses based on whether the combined signal is correctly received. Since only one set of ACK/NACK responses are generated for all of the softer handoff sectors, the base station can use the forward link in just one softer handoff sector to send the ACK/NACK responses to the mobile station, consuming fewer forward link transmit resources at the base station. Or, the base station can send the same ACK/NACK responses from two or more softer handoff sectors, thus allowing diversity combining of the ACK/NACK responses at the mobile station.

摘要： An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

摘要： A wireless communication network receives packet data transmissions from a mobile station, tracks the occurrence of retransmission requests sent to the mobile station responsive thereto, and modifies the radio link assignments for the mobile station based at least in part on said tracking. For example, a base station controller may be configured to manage the active set of a mobile station based on the number and/or frequency of NACK messages sent by the radio base stations in the mobile station's active set(s) responsive to packet data transmissions from the mobile station. The ACK/NACK response of a radio base station to mobile station transmissions may be used to detect link imbalance, identify poor reverse link channels, etc. The base station controller can add or change radio links based on the ACK/NACK response to improve reverse link performance, trigger voice call handoff, correct link imbalance, etc.

摘要： Outer loop power control (OLPC) for the reverse link considers frame information associated with at least two reverse link traffic channels, the transmit power of which is referenced to the transmit power of a reverse link pilot channel R-PICH. A traffic OLPC setpoint is determined based on information such as target frame error rate (FER) and actual frame errors associated with each traffic channel, and the traffic OLPC setpoint is converted to a R-PICH OLPC setpoint. The traffic OLPC setpoint may be calculated from weighted frame information generated by combining the received frame information. Alternatively, a traffic channel OLPC setpoint may be determined for each channel, and a weighted traffic OLPC setpoint calculated from the individual traffic channel OLPC setpoint. The setpoint adjustment may depend on received frame errors, where the power up step size is a multiple of the power down step size, the multiple calculated from target FERs.
摘要翻译：用于反向链路的外环功率控制（OLPC）考虑与至少两个反向链路业务信道相关联的帧信息，其发射功率参考反向链路导频信道R-PICH的发射功率。根据诸如目标帧错误率（FER）和与每个业务信道相关联的实际帧错误的信息来确定业务OLPC设定点，并且业务OLPC设定点被转换为R-PICH OLPC设定点。可以通过组合所接收的帧信息而生成的加权帧信息来计算交通OLPC设定点。或者，可以针对每个通道确定业务信道OLPC设定点，以及从各个业务信道OLPC设定点计算的加权业务OLPC设定点。设定点调整可能取决于接收的帧错误，其中上电步长是功率下降步长的倍数，从目标FER计算的倍数。

摘要： A symbol sequence contained in a received signal comprising a cyclic convolution of a Walsh code multiplexed signal and a channel impulse response of a multipath channel is detected using Walsh Hadamard domain equalization techniques. The method comprises converting the received signal and the channel impulse response of the multipath channel from the time domain to the WHT domain, and determining the symbol sequence based on equalizing the received signal in the WHT domain using WHT spectra of the channel impulse response to remove inter-symbol interference from the received signal due to cross-correlation between Walsh codes.
