Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for radio link monitoring for high speed user equipment (UE). For example, some embodiments are directed to a user equipment (UE) including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to monitor a downlink associated with a cell using a reference signal and estimate a downlink radio link quality associated with the downlink. The processor circuitry can further be configured to compare the estimated downlink radio link quality with a threshold. The processor circuitry can further be configured to trigger an out-of-sync operation in response to the downlink radio link quality being worse than the threshold. The threshold can include a value less than 10%.

Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to process a bandwidth part (BWP) switching request from a serving cell at slot n, and to perform an active BWP switch to a new BWP on the serving cell at a time no later than slot n+Y, wherein Y is a BWP switching delay. The one or more baseband processors are to accommodate a timing advance (TA) value to determine when to perform the active BWP switch. The apparatus can include a memory to store the BWP switching request.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for cell identification (ID) and beam ID detections in new radio (NR). The detections comprise NR primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection, PBCH DMRS detection, SS reference signal received power (RSRP) measurement, and slot/SS burst boundary timing acquiring. Various embodiments describe how to detect a cell ID and a beam ID in millimeter wave (mmWave) operation. Other embodiments describe further details regarding how to detect NR cell and beam ID during intra-frequency measurements.

Abstract: A method for bandwidth part (BWP) switching includes receiving an indication to switch operation of a user equipment (UE) configured for dual connectivity from a first BWP to a second BWP. At least one of an allowed interruption duration or an allowed BWP switch delay are determined for switching operation of the UE from the first BWP to the second BWP, where the allowed interruption duration is up to two subframes, and where the allowed BWP switch delay is at least one slot greater than two subframes. Operation of the UE is switched from the first BWP to the second BWP based on the at least one of the allowed interruption duration or the allowed BWP switch delay.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for quality-based measurements in new radio (NR). The measurements concern reference signal received quality (RSRQ) measurements and pertinent received signal strength indicator (RSSI) measurements, and signal-to-noise and interference measurements of synchronization signal (SS-SINR) in NR. Various embodiments describe how to measure the pertinent power levels in time domain and frequency domain. Other embodiments may be described and claimed.
