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: Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods to configure measurement gaps are generally described herein. A serving cell gNB may transmit, to a neighbor cell gNB, a channel state information reference signal (CSI-RS) status request message and may receive, from the neighbor cell gNB 105, a CSI-RS status update message. The serving cell gNB may determine, based on timing information in the CSI-RS status update message, a measurement gap to be reserved for transmission of CSI-RS from the neighbor cell gNB to a UE that is served by the serving cell gNB. The serving cell gNB may transmit, to the UE, control signaling that indicates the measurement gap. The serving cell gNB may receive, from the UE, a measurement report that indicates a signal quality measurement based on the CSI-RS from the neighbor cell gNB.

Abstract: Briefly, in accordance with one or more embodiments, user equipment (UE) comprising circuitry to connect to a network via a serving cell; and indicate to the network a measurement gap capability of the UE. The measurement gap capability includes information if the UE supports a carrier aggregation (CA) specific measurement gap and if the UE has two or more radio-frequency (RF) chains. The UE then receives a CA specific measurement gap configuration from the network for the two or more RF chains.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a downlink channel information (DCI) format 2_0 from a g-NodeB (gNB) connected to the 5G NR network, wherein the DCI format 2_0 includes channel occupancy time (COT) duration and a gap threshold value, determining if a nonzero power channel state information reference signal (NZP-CSI-RS) resource is valid, wherein the NZP-CSI-RS resource is valid if the NZP-CSI-RS resource is within the COT duration and if a gap between a last symbol of the DCI format 2_0 and a first symbol of the NZP-CSI-RS resource is greater than the gap threshold value.

Abstract: Approaches are described to enhance radio link monitoring and link recovery for the integration of non-terrestrial networks (e.g., satellites) into next generation wireless communication networks. Certain approaches describe the modification of block error rate threshold requirements based on the particulars of the satellites involved, and the procedure for making those modifications. Other approaches describe the modification of the evaluation period based on the particulars of the satellites involved, and the procedure for making those modifications. In making these modifications, user-equipment (UE)-specific margins are also considered. In addition, modifications to the procedure for higher priority cell search are also described when non-terrestrial wireless communication networks are involved.

Abstract: A user equipment including a transceiver and a processor is configured to receive, from a base station and via the transceiver, a set of resource indicators identifying a set of beams and a configuration for reporting a duty cycle for transmission in an uplink direction for at least one resource indicator of the set of resource indicators. The processor is also configured to, at least one of periodically or based on an event reported by a body proximity sensor (BPS), determine the duty cycle for transmission in the uplink direction for the at least one resource indicator of the set of resource indicators; and transmit, to the base station via using the transceiver, the determined duty cycle and the corresponding at least one resource indicator of the set of resource indicators according to the received configuration for reporting the duty cycle.
