Abstract:

Various aspects of the present disclosure generally relate to wireless communication, in some aspects, a user equipment (UE) may determine, for a first subscriber identity module (SIM) registered in a non-standalone mode, that a codebook configuration for a first cell is incorrect for the UE, based at least in part on transmitting a registration request for a New Radio (NR) data service to the first cell. The UE may add, for the first SIM, the first cell to a list of one or more cells to which registration requests for the NR data service are barred. The UE may determine, for a second SiM of the UE, that the first cell is on the list, and transmit, for the second SIM, a registration request to a second cell that is not on the list. Numerous other aspects are provided.
