摘要： From one perspective, a fixed rank r (r>1 is an integer) is determined from received signaling; at least one codeword of rank r is selected from a codebook of antenna weights for controlling inter-cell interference between a serving cell and a neighboring cell; and the selected at least one codeword of rank-r is reported to the serving cell. From a different perspective, the fixed rank r is derived and signaled to user equipments UEs operating in a serving cell; there is received from a UE in the serving cell a report indicating the at least one rank-r codeword; and an indication of the at least one rank-r codeword is forwarded to the neighboring cell. Methods, apparatus and computer programs are detailed as well as embodiments in which different ranks are used for different neighboring cells and narrowband/wideband PMI reporting which can also be different for different neighboring cells.

摘要： Systems and techniques for communication using coordinated multi-point transmission. In one embodiment, an apparatus comprises at least one processor and a memory storing a set of computer instructions. The processor is configured to cause the apparatus to receive information relating to a propagation delay variation between at least a first transmission and a second transmission received at a user equipment. The first transmission is received from a first transmission point and the second transmission is received from a second transmission. The information relating to the propagation delay variation is evaluated and, based on the result of the evaluation, a determination is made as to whether the second transmission point is acceptable as a participant in a cooperative multi-point joint processing transmission to the user equipment.

摘要： Signalling information relating to Multiple Input Multiple Output MIMO channel state information characteristics that a user equipment UE determines to be highest priority for a downlink is transmitted uplink from a the UE to a node of a cellular wireless network. The UE receives an indicator from the node indicating a preferred basis of the highest priority signalling information. The UE compiles the highest priority signalling information according to the preferred basis, and sends the compiled signalling information to the node. If the UE determines that the number of MIMO layers preferred for use for the downlink is one, then signalling information is sent in different messages indicating a first and second codeword respectively, the first codeword being selected to be a closest codeword to an intended MIMO channel state information characteristic, and the second characteristic is selected to be a less close codeword.
