Method and apparatus for allocating a control channel resource of a relay node in a backhaul subframe
A method and apparatus for allocating control channels of a relay is provided. The method includes generating resource block assignment information related to resource blocks allocated to the relay; transmitting resource information comprising the resource block assignment information; and transmitting a control channel according to the resource information.
1. A method for configuring control channel resources of a relay by a base station, the method comprising:
generating resource block assignment information related to resource blocks allocated to the relay and an indicator related to whether an interleaving is applied;
transmitting resource information comprising the resource block assignment information and the indicator; and
transmitting control information on a control channel based on the resource information.
2. The method of claim 1 , further comprising:
generating resource allocation type information related to a resource allocation type,
wherein the resource allocation type indicates one of a localized type and a distributed type.
3. The method of claim 1 , further comprising:
generating a reference signal (RS) indicator related to a reference signal used for demodulation,
the resource information further comprises the RS indicator.
4. The method of claim 1 ,
wherein if interleaving is applied, a common reference signal (CRS) is applicable, or else one of a CRS and a demodulation reference signal (DMRS) is applicable.
5. The method of claim 1 , wherein control channel resources for the relay is allocated in downlink data channel region for UE.
6. The method of claim 1 , wherein control channel resources for the relay is allocated in a backhaul subframe.
7. A base station for configuring control channel resources of a relay comprising:
a generator configured to generate resource block assignment information related to resource blocks allocated to the relay and an indicator related to whether an interleaving is applied; and
a transmitter configured to:
transmit resource information comprising the resource block assignment information and the indicator, and
transmit control information on a control channel based on the resource information.
8. The base station of claim 7 ,
wherein the generator further generates resource allocation type information related to a resource allocation type, and
wherein the resource allocation type indicates one of a localized type and a distributed type.
9. The base station of claim 7 ,
wherein the generator further generates a Reference Signal (RS) indicator related to a reference signal used for demodulation, and
the resource information further comprises the RS indicator.
10. The base station of claim 7 ,
wherein if interleaving is applied, a common reference signal (CRS) is applicable, or else one of a CRS and a demodulation reference signal (DMRS) is applicable.
11. The base station of claim 7 , wherein control channel resources for the relay is allocated in downlink data channel region for UE.
12. The base station of claim 7 , wherein control channel resources for the relay is allocated in a backhaul subframe.
