Embodiment Construction

[0042] Traditional configuration methods have their advantages and disadvantages. In order to reduce the size of the carrier configuration information transmitted between the base station and the terminal, and to make the configuration method more flexible, an exemplary embodiment of the present invention provides a carrier configuration method, which will use Carriers with the same configuration are classified into the same carrier group, and the base station sets the configuration of these carriers in a group manner. In addition, exemplary embodiments of the present invention also provide a carrier configuration method that can have resource configuration information based on the anchor carrier, and this carrier configuration method can be used in DRX and SPS. In this way, the carrier configuration method provided by the exemplary embodiments of the present invention can reduce the additional transmission and processing of RRC information.

Abstract

A carrier configuration method for a multi-carrier communication system having a base station (BS) and a terminal is described. The BS divides multiple component carriers (CCs) of the terminal to multiple CC groups, wherein the CCs using at least one identical configuration parameter are divided into the same CC group. The BS transmits a CC configuration message comprising at least one configuration parameter data to the terminal, wherein the configuration message comprises or does not comprise at least one CC configuration indicator. If the configuration message comprises the CC configuration indicator, the terminal will receive the CC configuration message, and configure the configuration parameter of the configurations of the CCs indicated by the CC configuration indicator according tothe configuration parameter data; otherwise, the terminal will configure the configuration parameter of the configurations of the default CCs (e.g. all of the CCs currently used by the terminal, or primary CCs).

Description

technical field [0001] The present invention relates to a multi-carrier communication system, and in particular to a carrier configuration method under the multi-carrier communication system. Background technique [0002] A multi-carrier terminal has the capability of transmitting and / or receiving multiple packets through one or more carriers (component carrier, CC for short). In order to control multiple carriers to complete different functions, the base station may set a specific configuration of the carrier of each terminal. For example, the base station may set the discontinuous reception (DRX) configuration of the carrier of the terminal or set the semi-persistent scheduling (Semi-Persistent Scheduling, SPS) configuration of the carrier of the terminal, wherein the DRX The configuration and the SPS configuration are two different configurations. The DRX configuration and the SPS configuration can exist at the same time, and only one can exist at the same time. If the ...
