Abstract

See full text

A method, performed by a UE, for handling a two-step Random Access Channel (RACH) procedure, in a wireless communications network is provided. When a Random Access (RA) event is triggered the UE obtains a Physical Random Access Channel (PRACH) preamble corresponding to the RA event and/or a desired grant size, by randomly select a preamble mapping to a table entry providing a required size of a Physical Uplink Shared Channel (PUSCH) resource for the triggered RA event. The UE then obtains a grant from the PUSCH resource table based on the obtained PRACH preamble, which grant includes an indication of a PUSCH resource to use for a Msg 3 transmission in uplink.
