Abstract
A method, apparatus, and system for multiplexing data for multiple wireless transmit/receive units (WTRUs) in a subframe are disclosed. A WTRU may receive a common control information message for a group of WTRUs time multiplexed in one subframe and a WTRU-specific control information message for a corresponding WTRU. The WTRU may determine whether the common control information message is directed to the WTRU based on a group WTRU identity. The WTRU may determine whether the WTRU-specific control information message is directed to the WTRU based on a WTRU-specific identity for the WTRU. The WTRU may receive a physical downlink shared channel on a WTRU-specific transmission time interval (TTI) within the subframe based on decoding common control information message with the group WTRU identity. The WTRU may decode the physical downlink shared channel using the common control information message and the WTRU-specific control information message for the WTRU.

Claim
1. A method for multiplexing data for multiple wireless transmit/receive units (WTRUs) in a subframe, the method comprising:
receiving, by a WTRU, a common control information message for a group of WTRUs time multiplexed in one subframe, and a WTRU-specific control information message for a corresponding WTRU, wherein the WTRU is part of the group of WTRUs; determining, by the WTRU, whether the common control information message is directed to the WTRU based on a group WTRU identity; determining, by the WTRU, whether the WTRU-specific control information message is directed to the WTRU based on a WTRU-specific identity for the WTRU; receiving, by the WTRU, a physical downlink shared channel on a WTRU-specific transmission time interval (TTI) within the subframe based on decoding of the common control information message with the group WTRU identity, wherein the WTRU-specific TTI for the WTRU is one of a plurality of WTRU-specific TTIs within the same subframe; and decoding, by the WTRU, the physical downlink shared channel using the common control information message and the WTRU-specific control information message for the WTRU.
2. The method of claim 1, wherein each WTRU-specific TTI is specific to a corresponding WTRU.
3. The method of claim 1, wherein each WTRU-specific TTI is specific to a plurality of corresponding WTRUs.
4. The method of claim 1, wherein the receiving the physical downlink shared channel is further based on decoding the WTRU-specific control information with the WTRU-specific identity for the WTRU.
5. The method of claim 1, wherein the group WTRU identity is decoded using cyclic redundancy check (CRC) bits.
6. The method of claim 1, wherein the WTRUs included in the group of WTRUs is dynamically changed for each transport block.
7. A wireless transmit/receive unit, part of a group of WTRUs, comprising:
a transceiver operatively coupled to a processor, the transceiver and the processor configured to receive a common control information message for the group of WTRUs time multiplexed in one subframe and a WTRU-specific control information message for a corresponding WTRU, determine whether the common control information message is directed to the WTRU based on a group WTRU identity, determine whether the WTRU-specific control information message is directed to the WTRU based on a WTRU-specific identity for the WTRU, receive a physical downlink shared channel on a WTRU-specific transmission time interval (TTI) within the subframe based on decoding of the common control information message with the group WTRU identity, and decode the physical downlink shared channel using the common control information message and the WTRU-specific control information message for the WTRU; and wherein the WTRU-specific TTI for the WTRU is one of a plurality of WTRU-specific TTIs within the same subframe.
8. The WTRU of claim 7, wherein each WTRU-specific TTI is specific to a corresponding WTRU.
9. The WTRU of claim 7, wherein each WTRU-specific TTI is specific to a plurality of corresponding WTRU.
10. The WTRU of claim 7, wherein the receipt of the physical downlink shared channel is further based on decoding the WTRU-specific control information with the WTRU-specific identity for the WTRU.
11. The WTRU of claim 7, wherein the group WTRU identity is decoded using cyclic redundancy check (CRC) bits.
12. The WTRU of claim 7, wherein the WTRUs included in the group of WTRUs is dynamically changed for each transport block.
13. A method for multiplexing data for multiple wireless transmit/receive units (WTRUs) in a subframe, the method comprising:
transmitting, by a base station, a common control information message for a group of WTRUs time multiplexed in one subframe, and a WTRU-specific control information message for a WTRU, wherein the WTRU is part of the group of WTRUs, wherein the common control information message is directed to the WTRU based on a group WTRU identity and the WTRU-specific control information message is directed to the WTRU based on a WTRU-specific identity for the WTRU; and transmitting, by the base station, a physical downlink shared channel on a WTRU-specific transmission time interval (TTI) within the subframe correlating to the common control information message with the group WTRU identity, wherein the WTRU-specific TTI for the WTRU is one of a plurality of WTRU-specific TTIs within the same subframe.
14. The method of claim 13, wherein each WTRU-specific TTI is specific to a corresponding WTRU.
15. The method of claim 13, wherein each WTRU-specific TTI is specific to a plurality of corresponding WTRU.
16. The method of claim 13, wherein the group WTRU identity is encoded using cyclic redundancy check (CRC) bits.
17. The method of claim 13, further comprising dynamically changing, by the base station, which WTRUs are included in the group of WTRUs for each transport block.
