Method for coordinated multi-point transmission and reception and corresponding base station

Abstract

The invention relates to a method for coordinated multi-point transmission and reception. The method comprises the following steps of: presetting a style set for coordinated multi-point transmission and reception on a base station; allocating a coordination base station group for each style in the style set, and correspondingly setting a selection condition, wherein the selection condition comprises a group of user terminal performance parameters and dereferencing requirements thereof; acquiring the dereferences of the user terminal performance parameters by a service base station for accessed user terminals to perform coordinated multi-point transmission and reception; selecting one style from the styles corresponding to the selection condition that the dereferences can meet; and performing coordinated multi-point transmission and reception on the user terminal by the coordination base station group allocated for the selected styles. Accordingly, the invention also provides the base station having the functions of coordinated multi-point transmission and reception. The base station comprises a coordinated multi-point module, a setting module and a selection module. The method and the base station can meet the performance requirements such as throughput, peak data rate and the like under different wireless communication environment conditions and effectively reduce system cost.

Description

Technical field [0001] The present invention relates to a wireless communication network, in particular to a method for multi-point coordinated transmission and reception and a corresponding base station. Background technique [0002] In the next-generation broadband wireless communication network, it is a key factor to solve the problem of user terminal (UT) throughput between cells, average user terminal throughput, especially the throughput and peak rate of cell edge user terminals, and Facing severe challenges. At present, in IEEE802.16j, IMT-Advanced, and WINNER, methods of sending and receiving Collaborative Multiple Point (CoMP) are proposed to solve this problem. [0003] The basic concept of CoMP transmission and reception is the joint transmission and reception between multiple coordinated base stations (Base Station, BS) and a single user terminal on the same wireless resource. There are two basic characteristics: [0004] (1) Each user terminal can be jointly served by...

Problems solved by technology

[0006] However, during the implementation of CoMP transmission and reception, using the same resource to serve a user terminal in multiple coordinated base stations will cause waste of resources; in the uplink with inter-cell interference, when selecting When the user terminal at the edge performs CoMP transmission and reception, it may cause serious inter-cell interference, which will significantly reduce the throughput, peak rate and average cell throughput of the cell edge
