摘要： A method (400) and apparatus (501) provide for rapid power control based on a quality related value, e.g. channel quality indicator (CQI) value. A transmit power level can be derived from a CQI value received according to a time period, e.g. corresponding to 500 Hz. A first predicted value can be predicted based on the CQI value, at a first time within the time period and a power adjustment value can be determined based on the CQI value as well as the first predicted value at a rate that exceeds the rate of receiving the CQI values. Note that other predicted values for or corresponding to the CQI value can be predicted at other times within the time period and that power adjustment values can be determined through interpolation between predicted values for any time within the period.

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。

摘要： To address the need to convey ACK/NACK information in a manner that conserves system and signaling resources, embodiments of the present invention employ a Node-B transmitting on two types of ACK/NACK broadcast channels (501, 502), one type for received uplink data that was scheduled by the Node B and the other type of broadcast channel for received uplink data that was not scheduled by the Node B. Other embodiments of the invention employ a Node-B transmitting on two types of broadcast channels, one type of broadcast channel for received uplink data that comes from non-SHO users and another type of broadcast channel for received uplink data that comes from non-scheduled users or comes from scheduled SHO users. In addition, ACK/NACK information is scheduled (800) into the available broadcast channel time slots in accordance with a transmission priority that is determined by a scheduler.

摘要： A communication system is provided that dynamically allocates power to a Multimedia Broadcast/Multicast Service (an MBMS service). In response to determining to establish a Point-to-Multipoint (PTM) communication channel to multiple user equipment (UEs), the communication service assigns the PTM communication channel to the MBMS service, determines a power requirement associated with each user equipment (UE) of the multiple UEs based on a handover quality measurement associated with the UE to produce multiple power requirements, and allocates a power level to the PTM communication channel based on the multiple power requirements. The communication system further dynamically adjusts the allocated power based on a handover quality measurement associated with a UE of the multiple UEs that is received during provision of the MBMS service.
