System and method for sharing a control channel for carrier aggregation
First Claim
1. A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, the method comprising the steps of:
- receiving activation signals specifying active and deactivated carriers from among the configured carriers;
for active carriers;
(i) identifying a number of CCE subset candidates to decode; and
(ii) decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and
for deactivated carriers, ignoring CCE subset candidates associated with the deactivated carriers.

Abstract
A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, the method comprising the steps of receiving activation signals specifying active and deactivated carriers from among the configured carriers, for active carriers (i) identifying a number of CCE subset candidates to decode and (ii) decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and for deactivated carriers, ignoring CCE subset candidates associated with the deactivated carriers.

8. A user equipment for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, comprising:
one or more processors configured to; receive activation signals specifying active and deactivated carriers from among the configured carriers; for active carriers; (i) identify a number of CCE subset candidates to decode; and (ii) decode up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and for deactivated carriers, ignore CCE subset candidates associated with the deactivated carriers. - View Dependent Claims (9, 10, 11, 12, 13, 14)
