摘要： A reference signal including a quality indication is injected into the reverse link signal received at a base station. The transmit power of the reference signal is controlled by the base station through reverse link power control, and the base station estimates the reverse link load from the transmit power of the reference signal. As the load increases, the transmit power must increase to overcome interference. The reference signal may be generated by a signal generator within the base station; by a mobile station hardwired to the base station; or by a mobile station proximate the base station, sending the reference signal over the air interface. The reverse link load may be estimated directly from reference signal transmit power, or from the reference signal transmit power minus a minimum reference signal transmit power in the absence of interference.

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 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： 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服务的移动站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。

摘要： When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.

摘要： Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.
