A further subtlety on the PHR cut-off time for CG-PUSCH in terms of the minimum PUSCH processing/preparation procedure time as defined in [TS 38.214] is that this timing only applies to dynamically scheduled PUSCH transmissions, so further details (such as clarification on BWP switching time, etc.) would be beneficial for the case of CG-PUSCH to ensure that the CG-PUSCH is the first/earliest UL resource for a new transmission only after the latest possible overriding physical downlink control channel (PDCCH) occasion. A possible solution was brought as a change request (CR) to 3GPP RAN Plenary #82 (December 2018), as copied below, but it was not agreed. It is expected that those changes get discussed and approved in 3GPP RAN1 #96 (February 2019). As for clarification of the details of the minimum PUSCH processing/preparation procedure time, the corresponding specifications text is also copied below from [TS 38.214].
