METHODS AND APPRATUSES FOR BUFFER STATUS REPORTING FOR DEVICE-TO-DEVICE COMMUNCATIONS

摘要

Embodiments described herein relate to a wireless device (300); a method therein for buffer status reporting; a network node (500) and a method therein for assigning resources. The method for the wireless device (300) comprises: determining (201 ) an amount of data in the buffer to be transmitted in addition to an amount of data previously transmitted but not acknowledged; transmitting (202) a buffer status report to the network node (500), the report including information on the determined amounts; and receiving (203) from the network node (500) a scheduling assignment for enabling the wireless device to transmit of the unacknowledged data and the remaining data in the buffer.
