Embodiment Construction

[0037] The basic idea of ​​the present invention is: the terminal selects the main control cell, and performs data interaction with the main control cell to obtain the neighbor cell list; the terminal measures the multi-point coordinated state information of the cell in the neighbor cell list, and generates a multi-point coordinated The candidate list of the coordinated auxiliary cell; when the terminal initiates a coordinated multi-point operation service, the candidate list is sent to the main control cell; the main control cell performs an activation decision on the cells in the candidate list to obtain the auxiliary cell for the terminal's coordinated multi-point operation , and send the activation list of the auxiliary cell to the terminal; the terminal maintains the activation list until the coordinated multi-point operation service ends.

[0038] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawing...

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. [0003] figure 1 It is a schematic diagram of the coordinated mult...
