摘要： Uplink overhead is significantly reduced in a MU-COMP wireless communication network (10) by exploiting the dissimilarity of received signal strength in signals transmitted by geographically distributed transmit antennas (14, 16), as seen by receiving UEs (18, 20). Each UE (18, 20) calculates a quantized normalization measure of channel elements for a channel weakly received from a first transmitter (14, 16) to that for a channel strongly received from a second transmitter (14, 16). The quantized normalization measure may be modeled as a ratio of complex Gaussian variables, and quantized in phase and amplitude by making simplifying assumptions. The ratios are quantized, and transmitted to the network (10) using far fewer bits than would be required to transmit the full channel state information. The network (10) uses the quantized normalization measures to set the transmitter (14, 16) weights.
摘要翻译：通过接收UE（18,20）可以看出，通过利用由地理上分布的发射天线（14,16）发射的信号中的接收信号强度的不相似性，MU-COMP无线通信网络（10）中的上行链路开销显着降低。每个UE（18,20）计算对于从第一发射机（14,16）弱弱地接收到从第二发射机（14,16）强烈接收的信道的信道的信道单元的量化归一化测量。量化的归一化度量可以通过简化假设来建模为复高斯变量的比率，并以相位和幅度量化。这些比率被量化，并且使用比传送全信道状态信息所需的位少得多的比特来传送到网络（10）。网络（10）使用量化的归一化措施来设置发射机（14,16）的权重。

摘要： User grouping is employed to tradeoff the COMP forward link capacity and required reverse link feedback, which makes the design of COMP practical and flexible. A channel element, such as the large scale fading, is measured for each distributed transmitter (14, 16) and UE (18, 20) pair based on reference signals, and the network (10) receives this information as feedback in the reverse link. The COMP determines a maximum cross interference level α req that is affordable, based on the available reverse link capacity for feedback. If this maximum cross interference level α req is exceeded, geographically separate UEs (18, 20) are divided into as few groups as possible, with UEs (18, 20) within each group separated, and the groups are allocated different time/frequency resource blocks. The grouping is done with the constraint that the cross interference does not exceed α req .
摘要翻译：用户分组用于权衡COMP前向链路容量和所需的反向链路反馈，这使得COMP的设计实用性和灵活性。基于参考信号，针对每个分布式发射机（14,16）和UE（18,20）对测量诸如大规模衰落的信道单元，并且网络（10）将该信息作为反向链路中的反馈。 COMP基于可用的反向链路容量来确定可承受的最大交叉干扰电平等级。如果超过这个最大交叉干扰级别等级，则将地理上分离的UE（18,20）分成尽可能少的组，每个组内的UE（18,20）被分离，并且分配不同的时间/频率资源块。分组完成的交叉干扰不超过等于的限制。
