摘要： In an Orthogonal Frequency Division Multiplexing communication system (100), a user equipment (102, 104) reports channel quality information that is sufficient to construct a fading profile of a frequency bandwidth and that does not consuming the overhead resulting from the reporting of CQI for every sub-band of the frequency bandwidth. In the communication system, the frequency bandwidth (320) may be represented by multiple sub-band levels (n), wherein each sub-band level comprises a division of the frequency bandwidth into a number of sub-bands different from the number of sub-bands of the other sub-band levels. The user equipment measures a channel quality associated with each sub-band of a sub-band level of the multiple sub-band levels, selects a sub-band of the sub-band level based on the measured channel qualities, and reports channel quality information associated with the selected sub-band to a radio access network.

摘要： Embodiments described herein address the desire to have a method for uplink rate control signaling that is able to achieve increased sector and user throughput with relatively high uplink spectrum efficiency. Rate control signaling embodiments are disclosed that use two common persistence values (404, 408) to update the allocated portion of RoT margin for each UE device, and thus, reduce the variation of the RoT. In addition, SHO information is used to control the inter-sector/cell interference and improve the sector throughput. In such embodiments, each UE determines (412) the data rate and time to transmit according to these common persistence values, SHO status and buffered data. Throughput comparable to that of time and rate schedulers, which require significantly more signaling and information, can be achieved by some of these embodiments while also exhibiting less sensitivity to delay, speed of the UE, and burstiness of the traffic.
摘要翻译：本文描述的实施例解决了希望具有上行链路速率控制信令的方法，其能够以相对高的上行链路频谱效率来实现增加的扇区和用户吞吐量。公开了速率控制信令实施例，其使用两个公共持续值（404,408）来更新每个UE设备的分配的RoT余量部分，并且因此减少RoT的变化。此外，SHO信息用于控制扇区间/小区干扰并提高扇区吞吐量。在这样的实施例中，每个UE根据这些公共持续值SHO状态和缓冲数据确定（412）数据速率和要发送的时间。可以通过这些实施例中的一些来实现需要显着更多的信令和信息的时间和速率调度器的吞吐量，同时对延迟，UE的速度和业务的突发性也表现出较小的灵敏度。
