1. A method of performing wireless communication using multiple carriers between a User Equipment (UE) and a base station, the method performed by the UE and comprising:
- receiving pairing information indicating a mapping relationship between a first carrier used for first link transmission and a second carrier used for second link transmission from the base station, the first carrier being one of an aggregation of first carriers, and the second carrier being one of an aggregation of second carriers;
receiving configuration information for the first carrier from the base station after receiving the pairing information, wherein the configuration information is used to configure radio access to the first carrier among the multiple carriers including the first carrier and the second carrier;
accessing the first carrier used for the first link transmission based on the configuration information;
configuring the second carrier for the second link transmission based on the first carrier according to the mapping relationship indicated by the pairing information;
performing the wireless communication using the configured second carrier; and
releasing the first carrier together with the configured second carrier through a carrier aggregation configuration message which indicates release of the first carrier,wherein the first link transmission is one of an uplink transmission and a downlink transmission and the second link transmission is the other one of the uplink transmission and the downlink transmission.
