1. A processor of a user equipment (UE) configured to perform operations comprising:
determining to perform a sounding reference signal (SRS) transmission with an antenna port switch operation, wherein the SRS transmission with the antenna port switch operation is performed during an SRS transmission occasion comprising one or more symbols of a slot;
generating, for transmission to a base station, a txSwitchImpactToRX information element (IE) or a txSwitchWithAnotherBand IE indicating one or more band combinations that are to be interrupted by the antenna switch port operation; and
applying one or more scheduling restriction rules corresponding to the SRS transmission with the antenna port switch to provide one or more scheduling restrictions for the UE,
wherein the scheduling restrictions cause the UE to omit performing at least one of transmission operations or reception operations during one or more symbols of the slot or one or more symbols of an adjacent slot.
