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 user equipment (UE) comprising:

circuitry configured to receive a first wireless signal of a control channel, wherein the first wireless signal comprises an N bit field and control information, and the N bit field comprises an N bit cyclic redundancy check (CRC) modulo two added to an N bit UE identity;

circuitry configured to determine whether criteria are met, wherein the criteria include the CRC is correct and the UE identity is any one of a plurality of UE identities associated with the UE; and

circuitry configured to use the control information to process a downlink shared channel on a condition that the criteria are met.

2. The UE of claim 1 further comprising circuitry configured to monitor a plurality of control channels.

3. The UE of claim 1 wherein at least one of the plurality of UE identities associated with the UE is unique to the UE.

4. The UE of claim 1 wherein at least one of the plurality of UE identities associated with the UE is an identity assigned to the UE.

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

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

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

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

9. A method implemented in a user equipment (UE) comprising:

receiving a first wireless signal of a control channel, wherein the first wireless signal comprises an N bit field and control information, and the N bit field comprises an N bit cyclic redundancy check (CRC) modulo two added to an N bit UE identity;

determining whether criteria are met, wherein the criteria includes the CRC is correct and the UE identity is any one of a plurality of UE identities associated with the UE; and

using the control information to process a downlink shared channel on a condition that the criteria are met.

10. The method of claim 9 further comprising monitoring a plurality of control channels.

11. The method of claim 9 wherein at least one of the plurality of UE identities associated with the UE is unique to the UE.

12. The method of claim 9 wherein at least one of the plurality of UE identities associated with the UE is an identity assigned to the UE.

13. The method of claim 12 wherein the identity assigned to the UE is unique within a subset of UEs operating in a wireless network.

14. The method of claim 9 wherein at least one of the plurality of UE identities associated with the UE identifies a group of UEs belonging to a plurality of subsets of UEs operating in a wireless network.

15. The method of claim 9 wherein at least one of the plurality of UE identities associated with the UE identifies a subset of UEs operating in a wireless network.

16. The method of claim 15 wherein the subset of UEs is one of a plurality of subsets.
