Abstract

A method in a relay station includes communicating with a base station, determining if a control signal is included in a subframe, and decoding data in the subframe if the control signal is included in the subframe. The control signal includes a parameter which is related to a quantity of resource blocks.

Claims

1. A method in a relay node, the method comprising:

communicating with a base station;

detecting a relay physical downlink control channel intended for the relay node in a subframe, wherein assignment of the relay physical downlink control channel is determined according to a resource block number configured based on a numeric value representing number of resource blocks configured for the relay physical downlink control channel; and

decoding a corresponding physical downlink shared channel (PDSCH) in the same subframe.

2. A relay node comprising:

at least one memory storing instructions; and

at least one processor configured to execute the instructions to;

communicate with a base station;

detect a relay physical downlink control channel intended for the relay node in a subframe, wherein assignment of the relay physical downlink control channel is determined according to a resource block number configured based on a numeric value representing number of resource blocks configured for the relay physical downlink control channel; and

decode a corresponding physical downlink shared channel (PDSCH) in the same subframe.
