Abstract

The embodiment of the invention discloses a method and equipment for determining a main transmission point. The method comprises the following steps of: configuring a transmission subset for user equipment by network side equipment; and transmitting configuration information of the transmission subset to the user equipment by the network side equipment, and indicating the user equipment to select a transmission point in the transmission subset as the main transmission point. In the embodiment of the invention, the transmission subset is configured in a measurement set by the network side equipment to ensure that the user equipment (UE) selects the main transmission point in the transmission subset configured by the network side equipment, and feeds a mark of the main transmission point back to the network side equipment, so the selection of the transmission point can be realized by the UE, the differentiated feedback of channel state information of different transmission points is realized, and the transmission point which transmits data to the UE is reasonably determined.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for determining a primary transmission point. Background technique [0002] CoMP (Coordinated Multiple Point Transmission, Coordinated Multiple Point Transmission) technology is the collaboration between multiple geographically separated transmission points. Generally, multiple transmission points are base stations in different cells, or multiple separate transmission devices in the same cell. Among them, CoMP technology is mainly divided into two categories: CS / CB (Joint Scheduling / Beamforming) and JP (Joint Processing). [0003] Through the coordination of time, frequency and space resources between cells, CS / CB allocates mutually orthogonal resources for different UEs (User Equipment, user equipment) to avoid mutual interference; since inter-cell interference is a constraint The main factor of the UE performance at the cell edge, so the CS / ...
