Abstract

A method and apparatus is disclosed wherein a user equipment (UE) receives control information on a first channel and uses the control information to process a second channel.

Claims

1. A Node-B comprising:

circuitry configured to process control information for a user equipment (UE) and producing an N bit cyclic redundancy check (CRC) associated with the control information;

circuitry configured to module 2 add the N bit CRC with an N bit UE identity to produce an N bit field wherein the UE identity is any one of a plurality of UE identities associated with the UE and the value of N is a positive integer; and

circuitry configured to transmit a wireless signal of a control channel wherein the wireless signal comprises the N bit field and the control information.

2. The Node B of claim 1, wherein the circuitry configured to transmit the wireless signal is further configured to transmit on any one of a plurality of control channels.

3. The Node B of claim 1, wherein at least one of the plurality of UE identities of the UE is unique to the UE.

4. The Node B of claim 1, wherein at least one of the plurality of UE identities of the UE is an identity assigned to the UE.

5. The Node B of claim 4, wherein the identity assigned to the UE is unique within a subset of UEs operating in a wireless network.

6. The Node B of claim 1, wherein at least one of the plurality of UE identities of the UE identifies a group of UEs belonging to a plurality of subsets of UEs operating in a wireless network.

7. The Node B of claim 1, wherein at least one of the plurality of UE identities of the UE identifies a subset of UEs operating in a wireless network.

8. The Node B of claim 7, wherein the subset of UEs is one of a plurality of subsets of UEs operating in a wireless network.

9. The Node B of claim 1, wherein the N bit field is derived from said any one of a plurality of UE identities.

10. A system comprising:

a user equipment (UE); and

a Node-B comprising;

means for processing control information for the UE and producing an N bit cyclic redundancy check (CRC) associated with the control information;

means for module 2 adding the N bit CRC with an N bit UE identity to produce an N bit field wherein the UE identity is any one of a plurality of UE identities associated with the UE and the value of N is a positive integer; and

means for transmitting a wireless signal of a control channel wherein the wireless signal comprises the N bit field and the control information.
