1. A method in a user equipment for determining a radio network temporary identifier (RNTI), the method comprising the steps of:
- descrambling a control channel;
decoding control messages included in the control channel wherein the decoded control messages include control bits and received cyclic redundancy check (CRC) bits;
generating a CRC from the decoded control bits;
determining the RNTI from the generated CRC and received CRC; and
utilizing the RNTI for decoding subsequent subframes.

Abstract
A method of determining a radio network temporary identifier (RNTI) includes descrambling a control channel, decoding control messages included in the control channel wherein the decoded control messages include control bits and received cyclic redundancy check (CRC) bits, generating a CRC from the decoded control bits, determining the RNTI from the generated CRC and received CRC and utilizing the RNTI for decoding subsequent subframes.

20. A computer program comprising computer readable program modules which when run on a user terminal causes the user terminal to:
-
descramble a control channel; decode control messages included in the control channel wherein the decoded control messages include control bits and received cyclic redundancy check (CRC) bits; generate a CRC from the decoded control bits; determine the RNTI from the generated CRC and received CRC; and utilize the RNTI for decoding subsequent subframes.
