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： Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

摘要： In an Orthogonal Frequency Division Multiplexing communication system, a user equipment 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 may be represented by multiple sub-band levels, 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： A communication system optimizes cell edge performance and spectral efficiency by determining an adaptive power control parameter based on system performance metrics measured by a serving Node B and further measured by, and reported to the serving Node B by, neighboring Node B's. The adaptive power control parameter is then used to determine an uplink transmit power of a user equipment (UE) served by the serving Node B. The uplink transmit power may be determined by the Node B and then conveyed to the UE, or the Node B may broadcast the adaptive power control parameter to the UE and the UE may self-determine the uplink transmit power. In addition, as a frequency reuse factor of one has been proposed for such communication systems, interference levels may be even further improved by employment of an intra-site interference cancellation scheme in the sectors serviced by the Node B.
摘要翻译：通信系统通过基于由服务节点B测量的系统性能指标来确定自适应功率控制参数来优化小区边缘性能和频谱效率，并由相邻节点B进一步测量并向服务节点B报告给服务节点B. 然后，使用自适应功率控制参数来确定由服务节点B服务的用户设备（UE）的上行链路发射功率。上行链路发射功率可以由节点B确定，然后传送给UE，或者节点B 可以向UE广播自适应功率控制参数，并且UE可以自行确定上行链路发射功率。另外，由于已经为这种通信系统提出了一种频率复用因子，所以通过在由节点B服务的扇区中采用站内干扰消除方案，甚至可以进一步改善干扰水平。
