摘要： Embodiments of the present disclosure provide a method and an apparatus for communication of an access point clusters. The access point cluster and a further access point cluster serve a plurality of UEs. The method may comprise: determining initial transmission power of each of the plurality of UEs and channel gain and noise power between each of the plurality of UEs and each access point in the access point cluster; obtaining optimized transmission power of a UE for the access point cluster based on the channel gain and the noise power of the UE and the initial transmission power and the channel gain of other UEs of the plurality of UEs; and if the optimized transmission power of the UE for the access point cluster is smaller than the optimized transmission power of the UE for the further access point cluster, determining that the optimized transmission power for the access point cluster is to be used by the UE to transmit a signal to the access point cluster.

摘要： Embodiments of the present disclosure relate to a method of forming a virtual cell in a heterogeneous network, a macro base station and a transmission point device. At a macro base station, terminal devices and transmission points cooperating with the macro base station in a macro cell of the macro base station are divided into at least a first set of devices and a second set of devices based on positions of the terminal devices and positions of the transmission points, the first set of devices and the second set of devices being adjacent and non-overlapping and each including at least one of the transmission points and at least one of the terminal devices. For a target terminal device in the first set of devices, channel state information between the target terminal device and the transmission points in the first set of devices and in the second set of devices is acquired. A power constraint for the transmission points is determined based on the channel state information, and based on the power constraint, at least one of the transmission points is selected for the target terminal device from the first set of devices to construct a virtual cell. Thereby, an interference coordination scheme is achieved which enhances the network performance while realizing low transmission signaling overhead and computational costs, and thus a construction of a virtual cell for the terminal device is facilitated.
