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： Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

摘要： In a radio network in which multiple base stations can communicate with multiple user terminals in a coordinated way, user terminals may be grouped into groups, each group representing a coordination scheme to be used for user terminals in the group. The groups may be chosen, for example, according to path loss or QoS requirements Preferably there are three groups requiring no coordination, multiuser coherent coordination and single user coherent coordination respectively. Grouping may be done dynamically according to one or more of the following factors: - the terminal's signalling overhead - the affordable processing complexity - the traffic load - the radio conditions. The grouping unit may be placed in one or more base stations or in any other suitable unit in the network.

摘要： The present application discloses systems and methods for reducing output-to- input feedback signal interference caused by a forwarding node that is configured to forward information received from a transmitter. In some embodiments, this output-to- input feedback signal interference is compensated for by the transmitter. For example, the transmitter is configured such that the signal that is transmitted by transmitter to the forwarding node includes both (1) a primary signal or 'desired' signal (e.g., the signal that is intended for a receiving device) and (2) a filtered version of the primary signal. The filter that produces the filtered version of the primary signal is configured (e.g., the filter's filter weights are adapted) such that the filtered version of the primary signal cancels or reduces the undesired output-to-input feedback signal.
