Problems solved by technology

[0005] However, whether it is the existing downlink CoMP technology or the existing uplink CoMP technology, they only use the interaction relationship between multiple points to remove the interference of each other as much as possible, but cannot eliminate all interference
[0006] In addition, the existing uplink CoMP technology occupies too much X2 link when transferring data between base stations, thus reducing the switching performance between cells
Moreover, the realization of the existing uplink or downlink CoMP technology usually requires the self-calculation process between different base stations, which puts a certain pressure on the calculation of the base station, and also reduces the efficiency of coordinated multi-point transmission

Abstract

The embodiments of the invention provide a coordinated multi-points transmission / reception method and apparatus. The method includes the following steps: after the after the coordinated calculation of a base station, transmitting a detection signal to the base station, such that the base station conducts channel detection based on the detection signal; receiving the result of the channel detection from the base station; analyzing the result of the channel detection to obtain a corresponding inverse noise; and transmitting the inverse noise to the base station. According to the embodiments of the invention, the method can suppress noise in a void network environment so as to improve network environment and increase transmission properties.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a coordinated multi-point transmission method and a coordinated multi-point transmission device. Background technique [0002] In order to improve the performance of cell edge users and meet the requirements of cell edge spectrum efficiency, CoMP (Coordinated Multi-Points Transmission / Reception) technology is introduced into the LTE-A (Long Term Evolution-Advanced) system. The CoMP technology provides services for a cell edge user at the same time through the cooperation of multiple adjacent base stations or nodes, so as to reduce the co-channel interference of the cell edge user from neighboring cells and improve the service quality of the cell edge user. Specifically, the CoMP technology may include: downlink CoMP and uplink CoMP technology. [0003] Existing downlink CoMP technologies are mainly divided into two categories: JT (Joint Transmission, Joint Transmi...
