Method for configuring a backhaul link subframe in a wireless communication system to which a carrier aggregation scheme is applied and an apparatus for the same
First Claim
1. A method for processing signals at a user equipment (UE) in a Time Division Duplex (TDD) wireless communication system, the method comprising:
- receiving, from a base station (BS), a control signal in a downlink subframe via a first cell configured with a first subframe configuration;
receiving, from the BS, a data signal based on the control signal in the downlink subframe via a second cell configured with a second subframe configuration that is a different subframe configuration than the first subframe configuration; and
transmitting, to the BS in an uplink subframe, a response signal corresponding to the data signal,wherein a relationship between the downlink subframe and the uplink subframe is defined based on the first subframe configuration.

Abstract
A method for configuring a backhaul link subframe in a wireless communication system to which a carrier aggregation scheme is applied and an apparatus for the same are disclosed. The method comprises determining one of a plurality of subframe configurations as a first subframe configuration for a primary component carrier allocated to the relay node; configuring subframe configuration candidates for one or more secondary component carriers allocated to the relay node on the basis of the determined first subframe configuration; determining a second subframe configuration for each of the one or more secondary component carriers by using the configured subframe configuration candidates; and transmitting and receiving a signal to and from the relay node in accordance with the first subframe configuration and the second subframe configuration.
