Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

Abstract: In embodiments, a UE may measure system frame number (SFN)/subframe timing differences between a master eNB (MeNB) and secondary eNB (SeNB) for dual connectivity (DC). When network-based reporting on the SFN/subframe timing offset is used, no new radio access network (RAN) signaling may be needed. However, in the case of multi-vendor deployments, no network coordination via different Operations, Administration, and Maintenance (OAM) for DC may occur. In this case, the network may not be able to obtain SFN/subframe timing offset information. To address this issue, various embodiments disclosed herein include UE-based reporting on SFN/subframe offset between an MeNB and an SeNB.

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.
