Buffer Status Reports (BSR), by which the network is made aware of uplink transmission needs of wirless devices, are specifically enabled to be transmitted using 2-step Random Access (RA), to reduce latency and network resource use. In one embodiment, 2-step RA configurations tailored to B SR-transmissions are introduced. These may, for example, use a subset of the configured resources in the configured 2-step RA resources for B SR. In another embodiment, conditions for triggering B SR over 2-step RA, depending on the traffic, are introduced. For example, the priority or the the delay budget of the traffic may be used to determine whether a BSR over 2-step RA should be triggered. In another embodiment, simplified procedures when receiving the response to MsgA are introduced. These may include, for example, not transmitting a full MsgB, but rather having the UE receive an UL grant.
