Method, base station, terminal and communication system for selecting a component carrier

摘要

A method, base station, terminal and communication system for selecting a component carrier are provided in the present invention. The method includes the following steps: determining the coverage range of each available carrier which can be used by the terminal; determining whether the distribution of the coverage ranges of all available carriers accords with a preset distribution mode; in the case of according with the presetting distribution mode, at least according to a rule which is determined by the distribution mode, determining a component carrier to be used. With the embodiments provided in the invention, a component carrier used by the terminal can be reasonably chosen.

1. A electronic device, comprising
processing circuitry configured to, enable a random access procedure on a component carrier for a user equipment; conduct a secondary component carrier selection for the user equipment based on a coverage distribution and signal quality of different available carriers; and generate for the user equipment a radio resource control reconfiguration information comprising radio resource configuration information of one or more secondary component carriers selected through the secondary component carrier selection, wherein the component carrier is designated as a primary component carrier of the user equipment, and the primary component carrier and one or more secondary component carriers support communications with the user equipment in a carrier aggregation communication scheme.
