METHOD FOR TRANSMITTING A SIDELINK BUFFER STATUS REPORTING IN A D2D COMMUNICATION SYSTEM AND DEVICE THEREFOR

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a sidelink buffer status reporting in a D2D communication system, the method comprising: transmitting information related to a first destination information list including at least one groupcast destination ID and a second destination information list including at least one unicast destination ID; assigning values of destination index to groupcast destinations IDs in listing order in the first destination information list and remaining values of the destination index after setting to the groupcast destinations IDs to unicast destinations IDs in listing order in the second destination information list, sequentially; generating and transmitting a SL BSR MAC CE including at least one destination index field identifying at least one destination, when SL BSR is triggered.

1. A method for a user equipment (UE) operating in a wireless communication system, the method comprising:
transmitting information related to a first destination information list including at least one groupcast destination identifier (ID) and a second destination information list including at least one unicast destination ID; assigning, by the UE, destination index values, the assigning comprising:
sequentially assigning destination index values to groupcast destination IDs in an order corresponding to a sequential order of the first destination information list; andsequentially assigning any destination index values not corresponding to the order of the first destination information list to unicast destination IDs in an order corresponding to a sequential order of the second destination information list; generating and transmitting a SideLink Buffer Status Reporting (SL BSR) Medium Access Control (MAC) Control Element (CE) including at least one destination index field identifying at least one destination, when a SL BSR is triggered, wherein one of the at least one destination index field has one to one correspondence to one of the assigned destination index values.
