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: Methods, systems, apparatus, and computer programs, for implementing dual-connectivity handover. In one aspect, a method includes determining, by user equipment (UE), whether the UE is capable of simultaneous communication with a source cell and a target cell, generating, by the UE, a handover indicator, the handover indicator having one or more fields structuring data that indicates that the UE is capable of simultaneous communication with the source cell and the target cell, transmitting, by the UE, the handover indicator to an access node, and receiving, by the UE and from the access node based on receipt by the access node of the handover indicator, a command to perform handover.

Abstract: An approach is described for a user equipment (UE), wherein the UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry receives a reference signal from a source device via a radio link, wherein the reference signal is one of the synchronization signal block (SSB) signal or channel state information reference signal (CSI-RS). The processor circuitry measures a quality of the reference signal, and measures an evaluation time of the reference signal. The processor circuitry determines a first indicator of the radio link based on the quality of the reference signal, and determine a second indicator of the radio link based on the evaluation time of the reference signal. The processor circuitry then determines a status of a connection of the radio link based on the first indicator and the second indicator of the radio link, and generate a message based the status of the connection. The radio front end circuitry then transmits the message to the source device.

Abstract: A method, system, and computer-readable media for evaluating the accuracy of user equipment (UE) reference signal receive power (RSRP) measurements is disclosed. This includes determining both a total reference signal receive power (RSRP) accuracy and a RSRP baseband accuracy associated with the UE. This also includes executing a plurality of comparisons between the total RSRP accuracy, the RSRP baseband accuracy, and a plurality of accuracy thresholds, and then determining the UE passes a measurement accuracy test based on the plurality of comparisons.
