CARRIER AGGREGATION CONFIGURATION METHOD AND DEVICE

摘要

A carrier aggregation configuration method and device. The method comprises: a base station configuring a carrier aggregation group for a terminal, and setting configuration manners of different subframe upstream/downstream ratios for wireless frames of each component carrier in the carrier aggregation group. A method 1 is adopted: in the case that a hybrid subframe supports unidirectional transmission, the base station and the terminal agree upon a subframe type of a subframe at a subframe time of a hybrid subframe on a main component carrier as a reference subframe type, the transmission capability on the main component carrier and the sub-component carrier are allowed for a subframe with the subframe type at the subframe time of the hybrid subframe being the same as the reference subframe type, and the transmission capability on the sub-component carrier is forbidden for a subframe with the subframe type at the subframe time of the hybrid subframe being different from the reference subframe type. The solution solves the problems of uncertain subframe types of hybrid subframes and disorderly timing relations of hybrid automatic repeat requests, thereby meeting the demands for component carrier aggregation of different upstream/downstream ratios.
