Abstract:
1. A method for detecting sharing of a timing advance value, the method comprising: calculating, by a user equipment, a time offset between a downlink component carrier corresponding to at least one target uplink component carrier and a downlink component carrier corresponding to a predetermined uplink component carrier, wherein the downlink component carriers are adapted to carry wireless transmissions; and sending, by the user equipment, an indication of the time offset between the downlink component carriers to a base station, the indication of the time offset configured to be used by the base station to identify which target uplink carriers are eligible to share timing advance values with the predetermined uplink component carrier, wherein target uplink component carriers with a time offset greater than a first predetermined threshold are deemed ineligible to share a timing advance value with the predetermined uplink component carrier, and wherein target uplink component carriers with a time offset less than or equal to the first predetermined threshold are deemed eligible to share a timing advance value with the predetermined uplink component carrier.
