Abstract: Embodiments of an apparatus of a user equipment (UE) configured for operation in a fifth-generation system (5GS) are described herein. The UE comprises first and second array antennas for transmission of mmWave signals including a sounding-reference signal (SRS). In response to decoding radio-resource configuration (RRC) signalling that indicates antenna switching for SRS, the UE initiates a countdown timer and transitions the second array antenna from a low-power state to an active state. If a downlink control information (DCI) indicating SRS antenna switching is not received while the countdown timer is active, the UE generates a command to transition the second array antenna to a low-power state upon expiration of the countdown timer.

Abstract: A user equipment (UE) configured for operating in a fifth-generation (5G) new radio (NR) system may search for a 5G NR cell at Synchronization Signal (SS) block frequency positions associated with synchronization signal (SS) raster values. The UE may detect a Synchronization Signal Block (SSB) at one of the SS block frequency positions and may derive a cell reference frequency corresponding to a NR Absolute Radio Frequency Channel Number (NR ARFCN) value for the 5G NR cell from system information including a channel bandwidth. The frequency positions associated with the SS raster values are based on one or more Global Synchronization Channel Number (GSCN) values selected for the FR2 operating band n263. The cell reference frequency corresponds to one of a plurality of NR ARFCN values selected for the FR2 operating band n263.
