Abstract
Method and apparatus for multiplexing data for multiple wireless transmit/receive units (WTRUs) for high speed downlink channels are disclosed. 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.

Claim
1. A method for multiplexing data for multiple wireless transmit/receive units (WTRUs) for high speed downlink channels in a transmission time interval (TTI), the method comprising:
receiving, by a WTRU, a joint high speed shared control channel (HS-SCCH), the joint HS-SCCH including a common part and WTRU-specific parts, the common part including common control information for WTRUs time multiplexed in one TTI, and each of the WTRU-specific parts including WTRU-specific control information for a corresponding WTRU;
receiving, by the WTRU, a high speed physical downlink shared channel (HS-PDSCH) on a WTRU-specific timeslot within the TTI based on decoding of the joint HS-SCCH with a group WTRU identity;
determining, by the WTRU, whether the common part of the joint HS-SCCH is directed to the WTRU based on the group WTRU identity;
determining, by the WTRU, whether any one of the WTRU-specific parts of the joint HS-SCCH is directed to the WTRU based on a WTRU-specific identity; and
decoding, by the WTRU, the HS-PDSCH using the common control information and the WTRU-specific control information for the WTRU.
2. The method of claim 1 wherein each of the WTRU-specific parts include cyclic redundancy check (CRC) bits masked with a corresponding WTRU identity.
3. The method of claim 1 wherein all or part of each of the WTRU-specific parts is masked with corresponding WTRU identity bits or a bit sequence derived from the corresponding WTRU identity.
4. The method of claim 1 wherein all or a part of the common control information on the common part is masked with group WTRU identity bits or a bit sequence derived from the group WTRU identity.
5. The method of claim 1 wherein the common control information is not masked with any identity.
6. A method for multiplexing data for multiple wireless transmit/receive units (WTRUs) for high speed downlink channels in a transmission time interval (TTI), the method comprising:
receiving, by a WTRU, a high speed shared control channel (HS-SCCH), the HS-SCCH including a group WTRU identity shared by a group of WTRUs;
receiving, by the WTRU, a high speed physical downlink shared channel (HS-PDSCH) based on decoding of the HS-SCCH with the group WTRU identity, wherein the HS-PDSCH contains a medium access control (MAC) protocol data unit (PDU), wherein the MAC PDU includes a MAC header and a plurality of individual WTRU MAC payloads for a plurality of WTRUs, and wherein each individual WTRU MAC payload is a payload for a particular WTRU; and
retrieving, by the WTRU, one individual WTRU MAC payload for the WTRU from the MAC PDU based on corresponding control information in the MAC header on a condition that a dedicated WTRU identity for the WTRU is detected in the MAC header.
7. The method of claim 6 wherein the group WTRU identity is derived from the dedicated WTRU identity.
8. The method of claim 6 wherein the individual WTRU MAC payload is an individual MAC PDU for a particular WTRU.
9. A wireless transmit/receive unit (WTRU) comprising:
a transceiver operatively coupled to a processor, the transceiver and the processor configured to receive a joint high speed shared control channel (HS-SCCH), decode the joint HS-SCCH with a group WTRU identity, and receive a high speed physical downlink shared channel (HS-PDSCH) on a WTRU-specific timeslot within a transmission time interval (TTI) based on the decoding of the joint HS-SCCH, wherein the joint HS-SCCH includes a common part and WTRU-specific parts, and the common part includes common control information for WTRUs time multiplexed in one TTI, and each of the WTRU-specific parts includes WTRU-specific control information for a corresponding WTRU,
and wherein the transceiver and processor are configured to determine whether the common part of the joint HS-SCCH is directed to the WTRU based on the group WTRU identity, determine whether any one of the WTRU-specific parts of the joint HS-SCCH is directed to the WTRU based on a WTRU-specific identity, and decode the HS-PDSCH using the common control information and the WTRU-specific control information for the WTRU.
