Abstract
A method and apparatus for supporting communication buffer status reports (BSRs) are disclosed. A wireless device may transmit data to a wireless transmit/receive unit (WTRU) group, which may include a WTRU and further include its own respective at least one logical channel group. The wireless device may produce a BSR, which may include an indication associated with the logical channel group and an index indicating an amount of data for the logical channel group. The wireless device may transmit the BSR to an eNode-B. Then, the wireless device may receive receives allocation information for transmission to the WTRU group. Also, the BSR may further include a plurality of indications associated with a respective plurality of logical channel groups, and the plurality of logical channel groups may be grouped based on priority. The index may further include a total amount of data across all logical channels of the logical channel group.

Claim
1. A wireless device comprising:
a transceiver; and
a processor operatively coupled to the transceiver;
wherein the transceiver is configured to transmit data to a wireless transmit/receive unit (WTRU) group;
wherein the processor is configured to produce a first buffer status report, wherein the first buffer status report includes an indication for each of one or more logical channel groups and a respective index indicating an amount of buffered data, for the respective logical channel group and for transmission to the WTRU group;
wherein the transceiver is configured to transmit the produced first buffer status report to an eNode-B; and
wherein the WTRU group includes at least one WTRU and is associated with one or more logical channel groups.
2. The wireless device of claim 1, wherein after transmitting the first buffer status report, the transceiver is further configured to receive allocation information for transmission to the WTRU group.
3. The wireless device of claim 1, wherein the first buffer status report further includes a plurality of indications for a respective plurality of logical channel groups, wherein the plurality of logical channel groups are grouped based on priority.
4. The wireless device of claim 3, wherein the first buffer status report further includes a plurality of indexes for the respective plurality of logical channel groups.
5. The wireless device of claim 3, wherein the plurality of logical channel groups reported in the first buffer status report are ordered based on the priority.
6. The wireless device of claim 1, wherein the transceiver is further configured to transmit to the eNode-B a second buffer status report for buffered data that the wireless device intends to transmit to the eNode-B.
7. The wireless device of claim 1, wherein the index identifies a total amount of data across all logical channels of the logical channel group.
8. A method for use in a wireless device, the method comprising:
transmitting, by the wireless device, data to a wireless transmit/receive unit (WTRU) group;
producing, by the wireless device, a first buffer status report, wherein the first buffer status report includes an indication for each of one or more logical channel groups and a respective index indicating an amount of buffered data, for the respective logical channel group and for transmission to the WTRU group;
transmitting, by the wireless device, the produced first buffer status report to an eNode-B; and
wherein the WTRU group includes at least one WTRU and is associated with one or more logical channel groups.
9. The method of claim 8, wherein after transmitting the first buffer status report, the wireless device receives allocation information for transmission to the WTRU group.
10. The method of claim 8, wherein the first buffer status report further includes a plurality of indications for a respective plurality of logical channel groups, wherein the plurality of logical channel groups are grouped based on priority.
11. The method of claim 10, wherein the first buffer status report further includes a plurality of indexes for the respective plurality of logical channel groups.
12. The method of claim 10, wherein the plurality of logical channel groups reported in the first buffer status report are ordered based on the priority.
13. The method of claim 8, further comprising:
transmitting to the eNode-B a second buffer status report for buffered data that the wireless device intends to transmit to the eNode-B.
14. The method of claim 8, wherein the index identifies a total amount of data across all logical channels of the logical channel group.
15. An eNode-B comprising:
a transceiver; and
a processor operatively coupled to the transceiver;
wherein the transceiver is configured to receive a first buffer status report from a wireless device, wherein the first buffer status report includes an indication for each of one or more logical channel group and a respective index indicating an amount of buffered data, for the respective logical channel group and for transmission to a wireless transmit/receive unit (WTRU) group, and wherein the WTRU group includes at least one WTRU and is associated with the one or more logical channel groups; and
wherein the processor and the transceiver are configured to schedule data transmissions in response to the received first buffer status report.
16. The eNode-B of claim 15, wherein after receiving the first buffer status report, the transceiver is further configured to transmit allocation information for transmission to the WTRU group.
17. The eNode-B of claim 15, wherein the first buffer status report further includes a plurality of indications for a respective plurality of logical channel groups, wherein the plurality of logical channel groups are grouped and ordered based on priority.
18. The eNode-B of claim 17, wherein the first buffer status report further includes a plurality of indexes for the respective plurality of logical channel groups.
19. The eNode-B of claim 15, wherein the transceiver is further configured to receive a second buffer status report for buffered data that a wireless device intends to transmit to the eNode-B.
20. The eNode-B of claim 15, wherein the index identifies a total amount of data across all logical channels of the logical channel group.
