Abstract
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 n th 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.

Claim
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.', '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.
2. The method of claim 1, further comprising:
determining, by the relay node, upon receiving the downlink data, whether the reception is successful or not.', 'determining, by the relay node, upon receiving the downlink data, whether the reception is successful or not.
3. The method of claim 1, further comprising:
receiving, by the relay node and from the base station, a Relay Physical Downlink Control Channel (R-PDCCH).', 'receiving, by the relay node and from the base station, a Relay Physical Downlink Control Channel (R-PDCCH).
4. The method of claim 1, wherein the values of n and k are expressed in form of a table.
5. A method for transmitting and receiving data, the method performed by a relay node and comprising:
receiving, by the relay node and from a base station, a downlink data;
transmitting, from the relay node to the base station, an ACK/NACK in response to the downlink data within an uplink subframe,
wherein the uplink subframe has a relationship based on k subframe with respect to a subframe within which the downlink data is received,

6. The method of claim 5, wherein the uplink subframe is a first uplink subframe among subsequent subframes from and including a 4th subframe from the subframe within which the downlink data is received.
7. The method of claim 5, wherein the subframe is allocated for an uplink from the relay node to the base station.
8. The method of claim 5, further comprising at least one of:
determining, by the relay node, upon receiving the downlink data, whether the reception is successful or not; and
determining, by the relay node, upon receiving the downlink data, the subframe within which the ACK/NACK is to be transmitted.', 'determining, by the relay node, upon receiving the downlink data, whether the reception is successful or not; and', 'determining, by the relay node, upon receiving the downlink data, the subframe within which the ACK/NACK is to be transmitted.
9. The method of claim 5, further comprising:
receiving, by the relay node and from the base station, a Relay Physical Downlink Control Channel (R-PDCCH).', 'receiving, by the relay node and from the base station, a Relay Physical Downlink Control Channel (R-PDCCH)
10. The method of claim 5, wherein the k is varied depending on a value of n, and
wherein the n is an index number of uplink subframe according to the HARQ process.', 'wherein the n is an index number of uplink subframe according to the HARQ process
11. A relay node for transmitting and receiving data, comprising:
a transceiver for receiving, from a base station, a downlink data; and
a processor cooperated with the transceiver and configured to determine, upon receiving the downlink data, whether the reception is successful or not, and to control the transceiver to transmit to the base station an ACK/NACK in response to the downlink data within an uplink subframe,
wherein the uplink subframe has a relationship based on k subframe with respect to a subframe within which the downlink data is received,
wherein the k is an index number of the downlink subframe according to a HARQ process allocated to the relay node,
wherein a value of k is varied depending on the HARQ process allocated to the relay node.', 'a transceiver for receiving, from a base station, a downlink data; and', 'a processor cooperated with the transceiver and configured to determine, upon receiving the downlink data, whether the reception is successful or not, and to control the transceiver to transmit to the base station an ACK/NACK in response to the downlink data within an uplink subframe,', 'wherein the uplink subframe has a relationship based on k subframe with respect to a subframe within which the downlink data is received,', 'wherein the k is an index number of the downlink subframe according to a HARQ process allocated to the relay node,', 'wherein a value of k is varied depending on the HARQ process allocated to the relay node
12. The relay node of claim 11, wherein the uplink subframe is a first uplink subframe among subsequent subframes from and including a 4th subframe from the subframe within which the downlink data is received
13. The relay node of claim 11, wherein the k is varied depending on a value of n, and
wherein the n is an index number of uplink subframe according to the HARQ process.', 'wherein the n is an index number of uplink subframe according to the HARQ process.']
