1. A method of buffer status reporting performed by a wireless device operative in a wireless communication network, the method comprising:
obtaining, from the wireless communication network, one or more configurations specifically for sending a Buffer Status Report (BSR) using a 2-step Random Access (RA) procedure by the one or more configurations defining at least one RACH opportunity as exclusive to the BSR reporting; and
transmitting, to the wireless communication network the BSR, in the MsgA of the 2-step RA;
wherein the one or more configurations is different to a configuration for a MsgA transmission which does not comprise a BSR.
