Method in which a relay allocates carriers on a backhaul link and an access link in a multi-carrier wireless communication system

摘要

The present invention relates to a wireless communication system, and more particularly, discloses a method and apparatus in which a relay allocates carriers on a backhaul link and an access link in a multi-carrier wireless communication system. The method in which the relay allocates resources in a multi-carrier wireless communication system in accordance with one embodiment of the present invention, comprises: determining a subframe pattern allocated on a first uplink component carrier to enable a backhaul uplink transmission from the relay to a base station; determining a subframe requiring reception of an access uplink from user equipment to the relay on the first uplink component carrier in accordance with a synchronous HARQ operation; and transmitting resource allocation control information containing carrier switching indicating information to the user equipment in the event the subframe requiring reception of an access uplink is determined to be the same as the subframe allocated for backhaul uplink transmission on the first uplink component carrier.

1. A method for allocating resources at a Relay Node (RN) in a multi-carrier supporting wireless communication system, comprising:
determining a subframe pattern for backhaul uplink transmission from the RN to a Base Station (BS) on a first uplink Component Carrier (CC); determining a subframe requiring access uplink reception from a User Equipment (UE) at the RN on the first uplink CC according to a synchronous Hybrid Automatic Repeat reQuest (HARQ) operation; and transmitting resource allocation control information including carrier switching indication information to the UE, if a subframe allocated for the backhaul uplink transmission is identical to the subframe requiring access uplink reception from the UE at the RN.
