Abstract: In a general aspect, a user equipment (UE) in a cellular communications network receives a first Synchronization Signal Block (SSB) corresponding to a first cell of the cellular communications network, and a second SSB corresponding to a second cell of the cellular communications network. The UE clarifies a first cell identifier (ID) of the first cell. The UE clarifies a second cell ID of the second cell. The UE determines an SSB measurement accuracy value using the first cell ID and the second cell ID.

Abstract: Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for user equipment (UE) idle mode operations. In embodiments, a UE wakes up more than once during a Discontinuous Reception (DRX) cycle. Inter-frequency measurement requirements may be relaxed based on DRX cycle length. Some embodiments include radiofrequency (RF) circuitry warm-up overhead reduction by on-duration separation with RF circuitry switching pattern adaption. Some embodiments include and RF circuitry warm-up overhead reduction by adaptive synchronization signal block (SSB) reference symbol down-selection. Other embodiments may be described and/or claimed.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may be configured for carrier aggregation (CA) in which a plurality of component carriers (CCs) are aggregated. The UE may determine a mapping of the CCs to a plurality of antenna panels for downlink reception, wherein a subset of the CCs are mapped to each antenna panel. The UE may transmit, to the gNB, radio resource control (RRC) signaling that indicates information related to the mapping. The gNB may, based at least partly on the mapping, determine, for each CC: a first scheduled time period for transmit beam refinement, and a second scheduled time period for receive beam refinement at the UE.

Abstract: A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for performing radio link monitoring or beam failure detection (RLM/BFD) in, or related to, a new radio (NR) involved network. Various embodiments are directed to adaptive configuration of threshold values for in-sync and/or out-of-sync (IS/OOS) in the NR involved network and adequately performing RLM/BFD. Such RLM/BFD with adaptive IS/OOS configuration may improve measurement accuracy and system performance. Other embodiments may be described and claimed.
