摘要： Users in a wireless communication system are provisioned into QoS-based classes and rate controlled using a single, per-sector common rate control (CRC) sub-channel. In one or more embodiments, different mobile stations are configured to respond differently to the same CRC commands by provisioning them with different Traffic-to-Pilot Ratio (TPR) tables and/or with different TPR step size adjustment tables. That is, the network can define different classes or groups of mobile stations by sending class or group-specific TPR-related values to the mobile stations belonging to a specific class or group. With this method, the mobile stations in one group can achieve different reverse link data rates, or make more aggressive data rate changes, than those in another group, even though both groups receive the same rate control commands.

摘要： A method and apparatus provide for setting the initial transmit power of secondary reverse link carriers used by mobile stations in conjunction with primary reverse link carriers. In one or more embodiments, a mobile station sets the initial transmit power of a secondary reverse link carrier relative to the transmit power of the primary reverse link carrier as a function of initialization transmit power information transmitted to the mobile station, which directly or indirectly considers reverse link loading information. Additional considerations may include differences in active sets associated with the primary and secondary reverse link carriers and/or sector switching activity of the mobile station.

摘要： A distributed transmit diversity system based on OFDM signaling transmits a broadcast/multicast service signal from one or more first base stations and from one or more second base stations, wherein the first and second base stations transmit orthogonalized pilots. Correspondingly, a remote receiver, e.g., a mobile station, resolves the orthogonal pilots and makes independent channel estimates relative to the first and second base stations for improved diversity reception. Pilots are orthogonalized between the first and second base stations by using orthogonal space-time or space-frequency block coding. For example, in one embodiment, a first pilot tone pair is interleaved with data tones in the OFDM data blocks being transmitted from the first base stations, while an orthogonal second pilot tone pair is interleaved with data tones in the same OFDM data blocks being synchronously transmitted from the second base stations.

摘要： A wireless communication network improves reverse link communication performance by changing one or more Automatic Repeat Request (ARQ) control settings as a function of measured or estimated reverse link loading. Control settings can be changed on a per-sector basis, allowing consideration of different loading conditions in different radio sectors of the network. Further, control settings can be changed for individual mobile stations, or selected groups of mobile stations, allowing different ARQ controls to be used for different mobile stations. By way of non-limiting example, a control circuit in a base station controller can be configured to take advantage of light reverse link loading conditions in a given radio sector by changing the ARQ control parameter(s) used for one or more mobile stations operating in that sector so that fewer ARQ retransmissions are required for those mobile stations to transmit reverse link data to the network.

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： 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： A communication station employs discontinuous transmission of channel quality feedback to reduce channel quality feedback transmitted over overhead channels. Prior to transmitting channel quality information to a remote station, the communication station compares the channel quality feedback to predetermined qualification criteria. If the qualification criteria are not met, the channel quality feedback is not transmitted. The method may be implemented by a mobile station to reduce channel quality feedback sent to a base station over a reverse link overhead channel.

摘要： A radio base station (RBS) provides dynamic rate adaptation for rate-adjustable communication channels used to transmit information to remote mobile stations based on monitoring transmit power information associated with those channels. For a given channel, the RBS tracks an average channel power on a per transmit frame basis and compares the average to first and second rate adjustment thresholds, which comparisons trigger downward or upward rate adjustments. Similar operation also may be based on averaging the power control commands returned by the mobile station, which indicate whether the channel's power as received by the mobile station is or is not sufficient with respect to a desired signal quality. This method thus provides a mechanism for rapid rate adaptation without requiring explicit rate control signaling from the mobile stations.

摘要翻译： 无线电基站（RBS）基于监视与这些信道相关联的发射功率信息，为用于向远程移动站发送信息的速率可调节通信信道提供动态速率适配。 对于给定的信道，RBS在每个发送帧的基础上跟踪平均信道功率，并将平均值与第一和第二速率调整阈值进行比较，该比较触发向下或向上速率调整。 类似的操作也可以基于平均由移动站返回的功率控制命令，其指示由移动站接收的信道的功率是否相对于期望的信号质量还不足够。 因此，该方法提供了用于快速速率适配的机制，而不需要来自移动台的明确的速率控制信令。
