Abstract

The invention provides a multipoint collaborative transmission processing method and a system. The method comprises the steps as follows: determining a sending mode of sending a common reference signal (CRS) to user equipment (UE), wherein the sending mode is to send the CRS only by a macrocell in a heterogeneous network or to send the CRS by the macrocell and a low-power node triggered to send the CRS; implementing the multipoint collaborative transmission processing according to the determined sending mode. Through the multipoint collaborative transmission processing method, the problems of low resource utilization rate and severe road damage fuzzy of the power control in the multipoint collaborative transmission of related technologies are solved, so that the resource utilization rate of the multipoint collaborative transmission is effectively improved, the road damage fuzzy of the power control is relieved to a certain extent, and the effect of covering backward users is guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for processing coordinated multi-point transmission. Background technique [0002] In order to improve the spectrum efficiency and user experience of cell edge users, LTE Release 10 and Release 11 introduce a multi-point coordinated transmission (Multi-point Coordinated Transmission and reception, CoMP for short) technology. The CoMP scenario 4 mentioned in LTE R11 has great advantages in many aspects. These advantages include: (1) There is no public reference signal (Common Reference Signal, CRS for short) between the Macro (macro cell) and the low-power node ) interference, reducing the dependence on CRS; (2) facilitating the orthogonality of Demodulation Reference Signal (DMRS) between cells; (3) enabling flexible channel state information-reference signal (Channel State Information –Reference Signal, referred to as CSI-RS) configuration; (4) Facilitate ...
