Abstract
Disclosed herein are methods and systems for uplink control feedback design in relation to the high speed dedicated physical control channel (HS-DPCCH). First uplink data may be transmitted on a HS-DPCCH to a first serving cell and a second serving cell, where the first serving cell may be used as a timing reference cell for the uplink transmission. The first serving cell may be associated with a first NodeB and the second serving cell may be associated with a second NodeB. First downlink data may be received from the first serving cell and second downlink data may be received from the second serving cell. A timing reference for uplink transmission may be changed such that the second serving cell may be used as the timing reference cell. Second uplink data may be transmitted on the HS-DPCCH using the second serving cell as the timing reference cell.
