METHOD AND APPARATUS FOR ALLOCATING RESOURCES IN CARRIER AGGREGATION SYSTEM

摘要

A method and apparatus for allocating resources in a base station (BS) in a carrier aggregation (CA) system is provided. The method and apparatus includes configuring a first cell and a second cell for a first user equipment (UE), identifying at least one second subframes of the first cell, the at least one second subframe being associated with feedback information to be received in a first subframe of the first cell, and at least one third subframes of the second cell, determining whether there is a downlink (DL) data transmission in the at least one third subframe of the second cell, and determining to allocate the other frequency resources, which are other than a frequency resource used for transmission of the feedback information in the first subframe, to a second UE, if there is no DL data transmission in the at least one third subframe of the second cell.

1. A method for allocating resources by a base station (BS) in a carrier aggregation (CA) system, the method comprising:
configuring a first cell and a second cell for a first user equipment (UE); identifying at least one second subframe of the first cell, the at least one second subframe being associated with feedback information to be received in a first subframe of the first cell, and at least one third subframe of the second cell; determining whether there is a downlink (DL) data transmission in the at least one third subframe of the second cell; and determining to allocate other frequency resources, which are other than a frequency resource used for transmission of the feedback information in the first subframe, to a second UE if there is no DL data transmission in the at least one third subframe of the second cell.
