Abstract
Techniques are provided to enable use of more than two preamble group Bs during random access (RA) for connected UEs. This flexibility is achieved by configuring the active BWP to overlap with the 2-step RA resources on the initial BWP, configuring different sizes of preamble group B in the initial BWP and the active BWP, a allowing connected UEs in the active BWP to use the MsgA PRACH and MsgA PUSCH resources in the initial BWP without switching active BWP.
