A secondary cell configuration method, communication method, base station, and user equipment

Abstract

The invention discloses a secondary cell configuration method. The method includes: preparing an association relationship among at least three secondary cells for the user equipment, the association relationship including a corresponding relationship that the user equipment can switch from each secondary cell to at least another secondary cell; sending the association relationship to the user equipment to configuring at least part of the at least three secondary cells to the user equipment, so that the user equipment uses at least one activated secondary cell to measure at least another inactive secondary cell corresponding to the activated secondary cell , and do not perform measurement on at least one inactive secondary cell that does not have a corresponding relationship with the activated secondary cell. The invention also discloses a communication method, base station and user equipment.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a secondary cell configuration method, a communication method, a base station and user equipment. Background technique [0002] In order to meet people's requirements for higher and higher communication rates, a concept of carrier aggregation is proposed in a Long Term Evolution advanced (LTE-Advanced) system. Aggregating carriers enables multiple continuous or discontinuous carriers under the same base station to be aggregated together for data transmission, and serve user equipment (User Equipment, UE) at the same time, so as to provide a required communication rate. [0003] Each carrier corresponds to an independent cell (Cell). The concepts of primary cell (PCell) and secondary cell (SCell) are defined, corresponding to the primary carrier and secondary carrier currently aggregated by the UE. The primary cell and all secondary cells are collectively referred to ...
