Methods of Multiple Point HSDPA Transmission In Single Or Difference Frequencies

摘要

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.

主权项

1. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to: transmit first uplink data on a high speed dedicated physical control channel (HS-DPCCH) to a first serving cell and a second serving cell, wherein the first serving cell is used as a timing reference cell; receive an radio resource control (RRC) message that indicates that the second serving cell is the timing reference cell; and transmit second uplink data on the HS-DPCCH to the first serving cell and the second serving cell using the second serving cell as the timing reference cell.
