Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to process a message received from a Fifth Generation (5G) NodeB (gNB) to perform one or more measurements in one or more target frequency layers, and for each of the one or more target frequency layers, to divide one or more other frequency layers into one of three categories comprising fully overlapped frequency layers, partially overlapped frequency layers, and non-overlapped frequency layers. The apparatus includes a memory to store the message.

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: 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: This disclosure describes methods, systems, and devices for handover of a user equipment (UE) from a source node of a radio access network (RAN) to a target node of the RAN. In one example, a method involves receiving, by the UE and from the source node, a RACH-498 handover message comprising: (i) an uplink grant for establishing a connection with the target node, and (ii) an identifier of a reference signal associated with a beam of the target node. The method also involves performing, by the UE, a handover based on the RACH-less handover message.

Abstract: A system, method, and apparatus is provided for performing testing using arrival of angles (AOA). The system, method, and apparatus can receive a first test signal from a first cell; receive a second test signal from a second cell; and perform a test based on AOA of the first test signal and the second test signal. At least one of the first test signal and the second test signal can include a channel state information-reference signal (CSI-RS) signal or a synchronization signal block (SSB) signal. The first test signal can include a different number of SSBs transmitted during an Measurement Timing Configuration (MTC) window when compared to the second test signal. The system, method, and apparatus can receive the first test signal and the second test signal in a time division multiple access (TDMA) manner. The first cell can include a serving cell and the second cell can include a neighboring cell of the serving cell. The system, method, and apparatus can receive the first test signal using a main lobe of an antenna and the second test signal using a side lobe of the antenna.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for radio link monitoring (RLM) evaluation period and layer 1 (L1) indication interval enhancements. A user equipment (UE) uses a scaling factor to scale the RLM evaluation period and/or the L1 indication interval. Different scaling factors may be used for different scenarios, conditions, or criteria. The same or different scaling factors may be used for the RLM evaluation period and the L1 indication interval. The scaling factor or a scaling factor index may be signaled to the UE by higher layer signaling. Other embodiments may be described and/or claimed.
