The base station may receive a first indication that the UE supports NR-CA with multiple PUCCH groups or NR-DC with multiple cell groups and a second indication that the UE does not support simultaneous Rx/Tx in a first frequency band and a second frequency band, and schedule communication with the UE to avoid scheduling the simultaneous Rx/Tx based on the first and second indications. The base station may avoid scheduling simultaneous Rx/Tx in a first cell group or a first PUCCH group including the first frequency band and a second cell group or a second PUCCH group including the second frequency band. The UE may skip reporting to the base station that the UE supports the NR-DC or the NR-CA with the first frequency band and the second frequency band.
