Abstract
A method and apparatus for supporting communication buffer status reports (BSRs) are disclosed. A wireless device may transmit data to at least one group of wireless transmit/receive units (WTRUs). The wireless device may produce a BSR, which may include an indication associated with a group of WTRUs and an indication of an amount of data that the wireless device has buffered to transmit to the group of WTRUs. The wireless device may transmit the BSR to an eNodeB (eNB). The BSR may include a plurality of indications associated with a respective plurality of groups of WTRUs and respective indications of amounts of data that the wireless device has buffered to transmit each of the plurality of groups. The indication of the amount of data that the wireless device has buffered to transmit to the group of WTRUs may identify a total across all logical channels of the group of WTRUs.

Claim
1. A wireless device comprising:
a transceiver operatively coupled to a processor, the transceiver and the processor configured to transmit data to at least one group of wireless transmit/receive units (WTRUs); the transceiver and the processor further configured to produce a buffer status report; wherein the buffer status report includes an indication associated with a group of WTRUs and an indication of an amount of data that the wireless device has buffered to transmit to the group of WTRUs; and the transceiver and the processor further configured to transmit the buffer status report to an eNodeB.
2. The wireless device of claim 1 wherein the buffer status report includes a plurality of indications associated with a respective plurality of groups of WTRUs and respective indications of amounts of data that the wireless device has buffered to transmit each of the plurality of groups.
3. The wireless device of claim 1 wherein the indication of the amount of data that the wireless device has buffered to transmit to the group of WTRUs identifies a total across all logical channels of the group of WTRUs.
4. The wireless device of claim 1 wherein the transceiver and the processor are further configured to receive configuration information from the eNode; wherein the configuration information includes a periodic timer; and wherein the transceiver and the processor are further configured to transmit buffer status reports for at least one group of WTRUs to the eNodeB based on the periodic timer.
5. A method comprising:
transmitting, by a wireless device, data to at least one group of wireless transmit/receive units (WTRUs); producing, by the wireless device, a buffer status report; wherein the buffer status report includes an indication associated with a group of WTRUs and an indication of an amount of data that the wireless device has buffered to transmit to the group of WTRUs; and transmitting, by the wireless device, the buffer status report to an eNodeB.
6. The method of claim 5 wherein the buffer status report includes a plurality of indications associated with a respective plurality of groups of WTRUs and respective indications of amounts of data that the wireless device has buffered to transmit each of the plurality of groups.
7. The method of claim 5 wherein the indication of the amount of data that the wireless device has buffered to transmit to the group of WTRUs identifies a total across all logical channels of the group of WTRUs.
8. The method of claim 5 further comprising:
receiving configuration information from the eNode; wherein the configuration information includes a periodic timer; and
transmitting buffer status reports for at least one group of WTRUs to the eNodeB based on the periodic timer.
9. An eNodeB comprising:
a transceiver operatively coupled to a processor, the transceiver and the processor configured to receive a buffer status report from a wireless device; wherein the buffer status report includes an indication associated with a group of WTRUs in communication with the wireless device and an indication of an amount of data that the wireless device has buffered to transmit to the group of WTRUs; and the transceiver and the processor configured to schedule data transmissions in response to the received buffer status report.
10. The eNodeB of claim 9 wherein the buffer status report includes a plurality of indications associated with a respective plurality of groups of WTRUs and respective indications of amounts of data that the wireless device has buffered to transmit each of the plurality of groups.
11. The eNodeB of claim 9 wherein the indication of the amount of data that the wireless device has buffered to transmit to the group of WTRUs identifies a total across all logical channels of the group of WTRUs.
12. The eNodeB of claim 9 wherein the transceiver and the processor are further configured to transmit configuration information; wherein the configuration information includes a periodic timer; and wherein the transceiver and the processor are further configured to receive buffer status reports for at least one group of WTRUs based on the periodic timer.
