Abstract

In an embodiment, a wireless transmit/receive unit (WTRU) may include: at least one antenna; a transceiver operatively coupled to the at least one antenna; and a processor operatively coupled to the transceiver. The at least one antenna is configured to receive a first signal that includes a control message. The transceiver and the processor are configured to recover the control message from the first signal. The control message includes a resource allocation, a group identification and subframe pattern information. The transceiver and the processor are further configured to produce a second signal that includes data associated with group identification. The processor is further configured to have the transceiver and the at least one antenna transmit the second signal in resources assigned by the resource allocation and in subframes derived from the subframe pattern information. The transceiver and the at least one antenna are further configured to transmit the second signal.

Claims

1. A wireless transmit/receive unit (WTRU) comprising:

at least one antenna;

a transceiver operatively coupled to the at least one antenna; and

a processor operatively coupled to the transceiver;

the at least one antenna is configured to receive a first signal, wherein the first signal includes a control message;

the transceiver and the processor are configured to recover the control message from the first signal, wherein the control message includes a resource allocation, a group identification and subframe pattern information;

the transceiver and the processor are further configured to produce a second signal, wherein the second signal includes data associated with the group transmission; and

the transceiver and the processor further configured to transmit the second signal via the at least one antenna in resources assigned by the resource allocation and in subframes derived from the subframe pattern information.

2. The WTRU of claim 1, wherein the at least one antenna is further configured to receive a third signal, wherein the third signal includes a second control message, having a resourcing assignment and a cyclic redundancy check (CRC) masked with an identification of the WTRU, and wherein the transceiver and the processor are further configured to recover the second control message.

3. The WTRU of claim 2, wherein the transceiver and the processor are further configured to produce a fourth signal in response to the second control message, and wherein the transceiver and the processor are further configured to transmit the fourth signal to a base station via the least one antenna, wherein the fourth signal does not include the data associate with the group transmission.

4. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

receiving a first signal, wherein the first signal includes a control message;

recovering the control message from the first signal based on an identification associated with a group transmission, wherein the control message includes a resources allocation and, in addition, subframe pattern information;

producing a second signal, wherein the second signal includes data associated with the group transmission; and

transmitting the second signal in resources assigned by the resource allocation and in subframes derived from the subframe pattern information.

5. The method of claim 4, further comprising:

receiving a third signal that includes a second control message having a resource assignment and a cyclic redundancy check (CRC) masked with an indetification of the WTRU; and

recovering the second control message.

6. The method of claim 5, further comprising:

producing a fourth signal in response to the second control message; and

transmitting the fourth signal to a base station, wherein the fourth signal does not include the data associated with the group transmission.
