Aspects presented herein enable updating the codebook configuration upon the changing of the cover or case of the UE. The apparatus applies a first codebook from a plurality of preconfigured codebooks. The apparatus detects a change of a cover state of the UE, wherein the change alters a transmission beam pattern at the UE. The apparatus applies a second codebook from the plurality of preconfigured codebooks based on the change of the cover state.

Methods and systems are provided to perform an adaptive access procedure on a multi-subscriber identity module (SIM) wireless communication device having at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that signaling on a random access channel (RACH) is required in order to establish access to a first network on a modem stack associated with the first SIM, identify a first protection window having a duration based on timing of an expected response by the first network to signaling on the RACH, and determine whether a tune-away period to decode a paging channel in a second network supported by the second SIM is scheduled to occur within the first protection window. If so, the wireless communication device may postpone signaling on the RACH until completion of the scheduled tune-away period.
