摘要： In a wireless communication network providing voice and data services, one or more entities in the network, such as a base station controller and/or radio base station, can be configured to reduce data services overhead responsive to detecting a congestion condition, thereby increasing the availability of one or more network resources for voice services. In one or more exemplary embodiments, one or more current data services users are targeted for modification of their ongoing data services to effect the reduction in data services overhead. Modifications can include, but are not limited to, any one or more of the following: forward or reverse link data rate reductions, and shifting of forward or reverse link traffic from dedicated user channels to shared user channels. Targeting of users for service modification can be based on reported channel quality information. For example, users reporting poor radio conditions can be targeted first for service modifications.

摘要： A wireless communication network manages variable data rate communication channels using both short-term data rate adaptation and longer-term resource allocation adjustment. For example, an exemplary base station system may track the actual transmit power being used to transmit a given communication channel on a per frame basis, or faster, and use that tracked value to infer changing channel conditions, e.g., for a given current data rate, higher power indicates poorer channel conditions and lower power indicates better channel conditions. Additionally, or alternatively, channel quality information reported by a receiving mobile station can be used. Regardless, relatively fast data rate changes can be made responsive to monitoring the channel conditions, while retaining the communication resource allocation for the channel. Over the longer term, however, the allocation itself can be changed, e.g., increased or decreased, depending on whether the channel is being efficiently utilized.
摘要翻译：无线通信网络使用短期数据速率适配和长期资源分配调整来管理可变数据速率通信信道。例如，示例性基站系统可以跟踪用于以每帧为基础或更快地发送给定通信信道的实际发射功率，并且使用该跟踪值来推断出改变的信道条件，例如对于给定的当前数据速率，较高的功率表示较差的信道条件，较低功率表示较好的信道条件。另外或者可以使用由接收移动台报告的信道质量信息。无论如何，可以在保持通道的通信资源分配的同时，监视通道状况来响应相对较快的数据速率变化。然而，从长远来看，分配本身可以根据信道是否被有效地利用而改变，例如增加或减少。

摘要： A wireless communication network provides priority for one type of users over another type of users relative to one or more network finite resources shared by the different types of users. For example, if the available forward link transmit power at a radio base station is being shared by voice and data users, the radio base station may give priority to the voice users by reducing the aggregate amount of power allocated to current data users if the combined level of power usage by the voice and data users reaches a defined release threshold. The release threshold may be set at a call-blocking threshold, such that dynamic release is invoked if the call-blocking level is reached. Other limited resources can be managed similarly, such as by setting a release threshold relative to spreading code usage, etc.
摘要翻译：无线通信网络相对于由不同类型的用户共享的一个或多个网络有限资源，为一种类型的用户提供超过另一类型的用户的优先级。例如，如果在无线电基站处的可用的前向链路发射功率正在由语音和数据用户共享，则无线电基站可以通过减少分配给当前数据用户的功率的总量来给语音用户优先，如果组合语音和数据用户的功率级别达到定义的释放阈值。释放阈值可以设置在呼叫阻止阈值，使得如果达到呼叫阻塞级别，则调用动态释放。可以类似地管理其他有限资源，例如通过设置相对于扩展码使用的释放阈值等。

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。

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 method of Common Rate Control (CRC) command generation considers status bits returned by mobile stations subject to CRC. The status bits from each mobile station, e.g., the Mobile station Status Indication Bits (MSIBs) defined by Release D of the IS-2000 standards, indicate whether the mobile station is capable of increasing its reverse link data rate, and may additionally indicate whether the mobile station has enough data for transmission to warrant a higher rate. Regardless, the status bits indicate how many in a group of mobile stations are capable of increasing their reverse link rates. Thus, a base station's command generation logic can take advantage of the additional knowledge gained from the status bits when generating CRC commands.
摘要翻译：公共速率控制（CRC）命令生成的方法考虑由CRC进行的移动台返回的状态位。来自每个移动站的状态位，例如由IS-2000标准的版本D定义的移动站状态指示位（MSIB）指示移动站是否能够增加其反向链路数据速率，并且还可以指示是否移动台具有足够的传输数据以保证更高的速率。无论如何，状态位表示一组移动台中有多少能够增加其反向链路速率。因此，当产生CRC命令时，基站的命令生成逻辑可以利用从状态位获得的附加知识。

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： 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.
摘要翻译：无线通信系统中的用户被提供到基于QoS的类别中，并使用单个每扇区通用速率控制（CRC）子信道进行速率控制。在一个或多个实施例中，不同的移动站被配置为通过用不同的业务对导频比（TPR）表和/或不同的TPR步长调整表来为相同的CRC命令作出不同的响应。也就是说，网络可以通过向属于特定类别或组的移动站发送类别或组特定TPR相关值来定义不同类别或移动站组。使用这种方法，即使两个组都接收到相同的速率控制命令，一组中的移动站可以实现与另一组中的移动站不同的反向链路数据速率，或者使得更积极的数据速率改变。

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.
摘要翻译：基站产生每小区ACK / NACK响应而不是每扇区ACK / NACK响应。对于在两个基站扇区的较软切换中接收到的给定移动站信号，如果软切换扇区中的至少一个正确地接收到该信号，则基站产生ACK响应，否则产生NACK响应。或者，基站可以组合较软切换信号，并且基于组合信号是否被正确接收来生成ACK / NACK响应。由于仅为所有更软切换扇区生成一组ACK / NACK响应，所以基站可以在仅一个较软切换扇区中使用前向链路来向移动台发送ACK / NACK响应，从而消耗较少的前向链路传输资源在基站。或者，基站可以从两个或更多个更软切换扇区发送相同的ACK / NACK响应，从而允许在移动站处的ACK / NACK响应的分集组合。

摘要： Reverse link reception and reverse link capacity are improved at a multi-sector radio base station (RBS) by forcing always-softer reverse link handoff conditions for mobile stations served by the RBS. Whenever a serving sector reverse link is assigned to a mobile station at the RBS, one or more additional reverse links are assigned to it from remaining sectors of the RBS. Such assignments are made irrespective of whether those sectors are, or could be, used to serve the mobile station on the forward link. The RBS improves its reception of the mobile station's reverse link transmissions by combining signals from all of the assigned reverse links. With improved reception, mobile stations can be commanded or configured to reduce their reverse link transmit power, thereby reducing reverse link interference and increasing reverse link capacity. Always-softer handoff may not be forced unless the mobile station has a reverse supplemental channel, since the use of such channels makes interference reduction particularly beneficial.
摘要翻译：在多扇区无线电基站（RBS）上，反向链路接收和反向链路容量得到改善，通过对由RBS服务的移动台强制总是更软的反向链路切换条件。每当服务扇区反向链路被分配给RBS的移动站时，从RBS的剩余扇区向其分配一个或多个附加反向链路。无论这些扇区是否被用于在前向链路上为移动站服务，都进行这样的分配。 RBS通过组合来自所有分配的反向链路的信号来改善其对移动台的反向链路传输的接收。通过改进的接收，可以命令或配置移动台以减少其反向链路发射功率，从而减少反向链路干扰并增加反向链路容量。除非移动台具有反向补充信道，否则始终更软的切换可能不被强制，因为使用这种信道使得干扰降低特别有利。
