Method and system for interactively selecting auxiliary cell

Abstract

The invention discloses a method for interactively selecting an auxiliary cell. The method comprises the steps of: selecting a master control cell by a terminal, and performing data interaction with the master control cell to obtain a neighbor cell list by the terminal; measuring multipoint coordination state information of cells in the neighbor cell list by the terminal, and evaluating a candidate list of multipoint coordination auxiliary cells by the terminal according to a measuring result; when the terminal initiates a multipoint coordination business, sending the candidate list to the master control cell; performing activation policy on the cells in the candidate list by the master control cell to obtain the auxiliary cell, for multipoint coordination operation, of the terminal, and sending an activation list of the auxiliary cell to the terminal; and maintaining the activation list by the terminal until the multipoint coordination operation business is completed. The invention further discloses a system for interactively selecting the auxiliary cell; and by means of the method and the system, a preferable neighbor cell can be selected to serve as the auxiliary cell through interaction, and the business quality and the user experience in the multipoint coordination operation are increased.

Description

technical field [0001] The invention relates to the selection of auxiliary cells in coordinated multi-point transmission and reception technology, in particular to a method and system for interactively selecting auxiliary cells. Background technique [0002] The Coordinated Multiple Point Transmission and Reception technology (Coordinated Multiple Point Transmission and Reception) is proposed to further meet the long-term evolution (Long Term Evolution, LTE) system for edge user throughput, edge user frequency utilization, and overall system performance. LTE-advanced, the successor of the LTE system, is designated by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) as an important element in its technical framework. The core idea of ​​this technology is to serve one user or multiple users at the same time through multiple transmission points with spatial location adjacency.
