1. User equipment (UE) comprising:
- circuitry to;
receive a wireless signal of a control channel, the wireless signal comprising an N bit field and control information, the N bit field comprising an N bit cyclic redundancy check (CRC) modulo two added to an N bit UE identity, wherein the value of N is a positive integer;
use the N bit UE identity to determine that the N bit CRC is correct; and
process, based on the determination, the control information.

8. User equipment (UE) comprising:
-
a receiver to receive downlink control information (DCI) and masked cyclic redundancy check (CRC) bits through a wireless communication system, the masked CRC bits comprising a CRC derived from the DCI, the CRC scrambled by a UE identity; and processor circuitry to determine that the CRC is correct and that the UE identity is one of a plurality of identities associated with the UE, and to process the DCI. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for processing control information at a user equipment (UE), the method comprising:
-
processing, at a physical layer of the UE, a mask comprising a cyclic redundancy check (CRC) of control information in a high speed shared control channel (HS-SCCH) combined with a UE identity, wherein if the UE identity is associated with the UE, the processing extracts the CRC from the mask for verification and forwards the control information from the physical layer to a medium access control (MAC) layer of the UE, and wherein if the UE identity is not associated with the UE, the processing discards the control information. - View Dependent Claims (16, 17, 18)
