Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] In the embodiment of the present invention, the CoMP transmission set of the UE may be a subset of the CoMP cooperating set. Optionally, the sending set of a UE includes the cells in the CoMP cooperating set of the UE whose CoMP configuration is activated, that is, the cells currently cooperating to send data to the UE. Optionally, the transmission set of the UE includes cells in the CoMP cooperating set of the UE whose CoMP configuration is activated a...

Abstract

The embodiment of the invention provides a method and a device for updating a CoMP (Coordinated Multi-point Transmission) sending set. The method for updating the CoMP sending set comprises the following steps: sending a 1k rule to UE (User Equipment) by an RNC (Radio Network Controller) and receiving a measurement report sent by the UE when the 1k rule is met, and updating the CoMP sending set of the UE by the RNC according to the measurement report, wherein the 1k rule contains any following condition for the UE to send the measurement report: cell mass of a cell which belongs to an activating set and does not belong to the CoMP sending set is more than the cell mass of at least one cell in the CoMP sending set, or cell mass of a cell which belongs to an activating set and does not belong to the CoMP sending set is more than an average value or weighted average value of the cell mass of at least two cells in the CoMP sending set. The method provided by the embodiment of the invention can be used for updating the CoMP sending set so as to flexibly adjust CoMP cooperated cells, thereby being beneficial to further improvements of the whole property of cells and the performance of cell edge users.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and equipment for updating a CoMP transmission set. Background technique [0002] In a coordinated multi-point transmission (Coordinated Multi-Point transmission, CoMP) technology, downlink coordinated multi-point transmission means that multiple geographically dispersed transmission points jointly transmit data for a user equipment (User Equipment, UE). [0003] A network node in a CoMP system includes a base station NodeB and at least one access point. An access point (Access Point, AS) is a node including a radio frequency transceiver, and a single antenna unit or multiple antenna units may be set on one access point. Multiple access points geographically dispersed and connected to network devices can cooperate to transmit data. The relationship between an access point and a cell in the traditional sense may be that one cell contains one access point, or one cell...
