摘要： To address the need for a resource allocation scheme that results in a better tradeoff between the cell-edge performance and the overall spectral efficiency, a communication system is provided that allocates uplink transmit power to user equipment (UEs) based on a fractional power control scheme. In another embodiment, since the cell-edge users are also likely to be power limited, the communication system may implement a minimized uplink transmission bandwidth resource allocation scheme that may work with the fractional power control scheme to achieve a level of performance desired for uplink transmissions in 3GPP (Third Generation Partnership Project) and 3GPP2 Evolution communication systems.

摘要： The present invention provides a method of scheduling asynchronous transmissions for a plurality of subscriber units. The method includes receiving information associated with a plurality of subscriber units that have uplink data to transmit, the information including uplink timing offset information associated with each of the subscriber units. Two or more subscriber units are then selected from a set of subscriber units having a timing offset differential, that is below a predetermined threshold, where the timing offset differential is the difference between the timing offset of a first subscriber unit and the timing offset of a second subscriber unit further selectively offset by a multiple of the transmission segment size, which minimizes the difference. The transmission segments, which are available for the uplink of data, are then allocated between the selected two or more subscriber units, which limits the number of transmission segments that have at least one of an overlap or a gap, and the amount of any overlap or gap, in order to minimize wasted scheduling opportunities.
摘要翻译：本发明提供了一种为多个用户单元调度异步传输的方法。该方法包括接收与具有要发送的上行链路数据的多个用户单元相关联的信息，所述信息包括与每个用户单元相关联的上行链路定时偏移信息。然后从具有定时偏移差分的一组用户单元中选择两个或更多个订户单元，该订户单元低于预定阈值，其中定时偏移差分是第一订户单元的定时偏移与第一用户单元的定时偏移之间的差第二用户单元进一步选择性地偏移传输段大小的倍数，这使差异最小化。可用于数据上行链路的传输段然后被分配在所选择的两个或多个用户单元之间，这限制了具有重叠或间隙中的至少一个的传输段的数量以及任何重叠的量或差距，以最小化浪费的调度机会。

摘要： A wireless communication system (100) and method for providing high speed uplink packet access from user equipment (128, 130) to a base station (114, 116, 118, 120). Each of the user equipment (128, 130) and the base station (114, 116, 118, 120) includes a transmitter (1106, 1206), a receiver (1104, 1204), and a controller (1108, 1208) coupled to the transmitter and the receiver. Data packets are transmitted from the user equipment (128, 130) to the base station (114, 116, 118, 120). Control information, corresponding to the data packets, is transmitted from the base station (114, 116, 118, 120) to the user equipment (128, 130). The control information includes an absolute grant channel indicator and/or channelization code(s) assigned to the user equipment (128, 130). The controller (1108) of the user equipment (128, 130) is configured to minimize a number of channelization code per scheduling active set cell to be monitored by the user equipment based on the absolute grant channel indicator and/or to utilize the channelization code(s) in response to handoff and/or entering an active channel state.

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。
