Abstract
A user equipment (UE), the UE including: a controller configured to control to trigger a Buffer Status Report (BSR) if an allocated uplink resource for a Transmission Time Interval (TTI) is capable of accommodating a Sidelink Buffer Status Report (BSR) Medium Access Control (MAC) Control Element (CE) containing a buffer status for at least one Sidelink Destination and its corresponding MAC subheader; and a transmitter configured to transmit the BSR, wherein, the controller controls to cancel all triggered Sidelink BSRs if no side-link data available for transmission exists.
Claims10
A user equipment (UE), the UE comprising:
- a controller configured to control to trigger a Buffer Status Report (BSR) if an allocated uplink resource can accommodate a Sidelink Buffer Status Report (BSR) Medium Access Control (MAC) Control Element (CE) containing a buffer status for at least one Sidelink Destination and its corresponding MAC subheader;
- and
- a transmitter configured to transmit the BSR, wherein,
- the controller controls to cancel all triggered Sidelink BSRs if all the side-link data available for transmission can be accommodated by a remaining of the allocated uplink resource.
A communication method comprising:
- controlling to trigger a Buffer Status Report (BSR) if an allocated uplink resource can accommodate a Sidelink Buffer Status Report (BSR) Medium Access Control (MAC) Control Element (CE) containing a buffer status for at least one Sidelink Destination and its corresponding MAC subheader;
- and
- transmitting the BSR, wherein,
- controlling to cancel all triggered Sidelink BSRs if all the side-link data available for transmission can be accommodated by a remaining of the allocated uplink resource.
A communication system comprising:
- a User equipment (UE) configured to control to trigger a Buffer Status Report (BSR) if an allocated uplink resource can accommodate a Sidelink Buffer Status Report (BSR) Medium Access Control (MAC) Control Element (CE) containing a buffer status for at least one Sidelink Destination and its corresponding MAC subheader and to transmit the BSR;
- and, a base station configured to receive the BSR wherein,
- the UE controls to cancel all triggered Sidelink BSRs if all the side-link data available for transmission can be accommodated by a remaining of the allocated uplink resource.
