1. A method in a base station associated with a relay node for controlling resource reservation of the relay node, the method comprising:
- reserving a first set of resource blocks out of a set of resource blocks in a subframe, for transmitting data to the relay node;
reserving a second set of resource blocks out of the set of resource blocks in the subframe, for enabling the relay node to schedule transmissions to a user equipment being served by the relay node;
informing the relay node about the reserved first and second set of resource blocks; and
transmitting control information to the relay node on the first set of resource blocks, the control information indicating if a first data was transmitted on the first set of resource blocks, and the control information configured to cause the relay node to determine if a second data was transmitted by the relay node on the first set of resource blocks simultaneous with the transmission of the first data on the first set of resource blocks.

Abstract
Exemplifying embodiments herein relate to a relay node and a method therein for communicating data to a user equipment, the relay node being associated with a base station, is provided. The method comprises receiving information from the base station indicating a first set of resource blocks of a subframe comprising control information. The method further comprises identifying, based on the received information, at least one resource block outside the first set of resource blocks, and scheduling, to the user equipment, transmissions on the at least one identified resource block.

5. A base station associated with a relay node and configured to control resource reservation of the relay node, the base station being configured to:
-
reserve a first set of resource blocks out of a set of resource blocks in a subframe for transmission of data to the relay node; reserve a second set of resource blocks out of the set of resource blocks in the subframe for enabling the relay node to schedule transmissions to a user equipment being served by the relay node; inform the relay node about the reserved first and second set of resource blocks; and transmit control information to the relay node on the first set of resource blocks, the control information indicating if a first data was transmitted on the first set of resource blocks, and the control information configured to cause the relay node to determine if a second data was transmitted by the relay node on the first set of resource blocks simultaneous with the transmission of the first data on the first set of resource blocks. - View Dependent Claims (6, 7, 8)
