    摘要： Systems, methods, and instrumentalities are disclosed to provide antenna transmit diversity. A wireless transmit/receiver unit (WTRU) may comprise multiple antennas. A channel condition for each of the antennas may be determined. A probing phase may be used in order to determine the channel conditions. During a period of the probing phase, a probing signal from each antenna may be transmitted during a respective time interval. The WTRU transmit power may or may not be held constant. A Node B may receive each probing signal and determine channel quality information. The Node B may adjust the determined channel quality information if there is a power offset between the signals. The Node B may send the channel quality information to the WTRU. The WTRU may switch an antenna to use for uplink transmission based on the received channel quality information.

    摘要： Systems and methods for managing control signaling overhead for a multi-carrier HSDPA (MC-HSDPA) may be disclosed. In particular, a plurality of downlink carriers may be received and bundled or paired. Configuration information indicative of the bundling may then be generated and transmitted. Additionally, one or more components such as antennas, user equipment (UE), and the like may receive an indication of a configuration or state via a high speed shared control channel (HS-SCCH) order where the indication includes order bits and order types and the configuration may be applied to activate and/or deactivate the components or operations such as uplink closed-loop transmit diversity (CLTD), uplink multiple-input multiple-output (MIMO). The order bits and/or order types may also be extended to support the activation/deactivation of additional carriers of MC-HSDPA.

    摘要： Method and apparatus for transmitting pilot on multiple antennas are disclosed. A wireless transmit/receive unit (WTRU) may transmit a primary dedicated physical control channel (DPCCH) and at least one secondary DPCCH via multiple antennas using different channelization codes. The first eight pilot symbols of the secondary DPCCH may be same as pilot symbols of length eight of the primary DPCCH. The secondary DPCCH may include a same number of pilot bits as the primary DPCCH in a normal mode and in a compressed mode, respectively. The transmit power of the secondary DPCCH may be adjusted based on a ratio of a number of pilot symbols in the primary DPCCH and the secondary DPCCH. When a required transmit power exceeds a maximum allowed transmit power of the WTRU, power scaling may be applied equally to the primary DPCCJ and the secondary DPCCH.

    摘要： A method and apparatus for sending feedback for multi-cell high speed downlink packet access (HSDPA) operations are disclosed. A wireless transmit/receive unit (WTRU) may generate and send hybrid automatic repeat request acknowledgement (HARQ-ACK) messages and/or channel quality indication (CQI) or precoding control indication/channel quality indication (PCI/CQI) messages for a plurality of cells via a plurality of high speed dedicated physical control channels (HS-DPCCHs) with a spreading factor of 128. Each HARQ-ACK message may be mapped to two cells and each CQI or PCI/CQI message may be mapped to one cell. The cells may be remapped to an HARQ-ACK message and a CQI or PCI/CQI message within an HS-DPCCH on a condition that any cell is activated or deactivated on that HS-DPCCH.

A WTRU may receive a joint high speed shared control channel (HS-SCCH) including a common part and WTRU-specific parts. The common part includes common control information for WTRUs multiplexed in one transmission time interval (TTI), and each of the WTRU-specific parts includes WTRU-specific control information for a corresponding WTRU. The WTRU receives a high speed physical downlink shared channel (HS-PDSCH) based on decoding on the joint HS-SCCH. The HS-SCCH may include a group WTRU identity shared by a group of WTRUs.
