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

摘要

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.

1. A method for processing signals at a user equipment in a TDD (Time Division Duplex) wireless communication system, wherein a first subframe configuration is configured for a primary cell and a second subframe configuration is configured for a secondary cell, the method comprising:
receiving, from a network, downlink data in a first subframe via the secondary cell; and transmitting, to the network in a second subframe, ACK (acknowledgement)/NACK (negative-ACK) information for the downlink data via the primary cell, wherein the first subframe configuration is a different configuration than the second subframe configuration, wherein a first subframe according to both the first subframe configuration and the second subframe configuration is a downlink subframe, and wherein the first subframe has an index n-k and the second subframe has an index n, and k is an integer determined based on the first subframe configuration.
