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 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： 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： 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 Forward Supplemental Channel (F SCH) serving sector for a packet data call to a mobile terminal in a CDMA network is dynamically selected by monitoring radio channel conditions at potential F SCH serving sectors. The sector loading at the potential F SCH serving sectors is also monitored. A new F SCH serving sector is then selected based on the sector loading and the channel condition measurements. Radio channel conditions may be monitored by PPSMM and/or CQI reports from the mobile terminal, monitoring the transmit power on the F FCH of sectors in the mobile terminal's active set, and monitoring the transmit power on the F SCH of the current serving sector. The new F SCH serving sector may be determined by estimating sector loading of each potential sector at each possible data rate, and selecting the sector offering the highest data rate and lowest loading at that rate.

摘要： A radio base station performs reverse link rate control in a wireless communication network by "stealing" bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

摘要： Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment (550) may generate and send a plurality of channel quality indicator (CQI) values to a base station (510). The base station (510) determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station (510) can transmit an adjusted measurement power offset (712) to the user equipment (550). On receipt of the adjusted measurement power offset (712), the user equipment (550) generates subsequent CQI values using the adjusted measurement power offset (712).

摘要： To determine a cell for usage in wireless communication, a signal-to-noise ratio or a signal-to-power ratio can be used in selecting an appropriate cell. However, cell selection can also configure to take both signal-to-noise ratio and signal-to-power ratio into account. Multiple available cells can be analyzed and a highest ranking cell can be selected through balancing the aforementioned ratios. In addition, to minimize transferring between cells, a limitation can be placed such that a cell is not left unless there is better of both the aforementioned ratios at another cell.
