Method for transmitting/receiving data between a relay and a base station

摘要

The present invention provides a method for transmitting/receiving data to/from a relay. The data transmitting/receiving method comprises the steps of: enabling the relay to receive data on an nth subframe of a downlink from a base station; determining the position of the subframe of an uplink to which data is to be transmitted, if any data to be transmitted exists, wherein the position of said subframe is determined as the (n+k)th subframe, wherein said k is determined by the value of said n and by information on a preset HARQ; and transmitting the data on an (n+k)th subframe of the uplink.

1. A method for transmitting and receiving data, the method performed by a relay node, the method comprising:
receiving, by the relay node and from a base station, a downlink data; and transmitting, from the relay node to the base station, in response to the reception of the downlink data, ACK/NACK within an uplink subframe n, wherein the n is an index number of the uplink subframe for transmitting the ACK/NACK, wherein a value of n is associated with a parameter related to subframe configuration, wherein the parameter is configured by high layers, wherein the downlink data is received within a subframe n-k, and wherein the value of k is equal to or more than 4.
