1. A method for a base station to transmit control information to a relay station and to user equipment, comprising:
- encoding, by the base station, first downlink control information appended with a first plurality of cyclic redundancy check (CRC) bits into a first group of control channel elements (CCEs), the first downlink control information indicating resource allocation for the relay station, wherein the first group of CCEs comprises one of 3 CCEs, 5 CCEs, 6 CCEs, and 7 CCEs;
encoding, by the base station, second downlink control information appended with a second plurality of CRC bits into a second group of CCEs, the second downlink control information indicating resource allocation for the user equipment, wherein the second group of CCEs comprises one of 1 CCE, 2 CCEs, 4 CCEs, and 8 CCEs;
transmitting, by the base station, the encoded first downlink control information and the encoded second downlink control information in a same subframe.

9. A method for a base station to transmit control information to a relay station and to user equipment, comprising:
-
encoding, by the base station, first downlink control information into a first group of control channel elements (CCEs), the first downlink control information indicating resource allocation for the relay station, wherein the first group of CCEs comprises one of 3 CCEs, 5 CCEs, 6 CCEs, and 7 CCEs; encoding, by the base station, second downlink control information into a second group of CCEs, the second downlink control information indicating resource allocation for the user equipment, wherein the second group of CCEs comprises one of 1 CCE, 2 CCEs, 4 CCEs, and 8 CCEs; transmitting, by the base station, the encoded first downlink control information in a first subframe, for the relay station to decode the first group of CCEs using a first parameter value associated with the relay station; and transmitting, by the base station, the encoded second downlink control information in a second subframe, for the user equipment to decode the second group of CCEs using a second parameter value associated with the user equipment, wherein the second subframe includes no downlink control information indicating resource allocation for the relay station. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
