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: Techniques are provided for mitigating inter-carrier interference (ICI) due to frequency multiplexed downlink channels with mixed numerologies. For example, a base station allocates, for a user equipment (UE), a first downlink (DL) channel and a second DL channel that are frequency multiplexed in a same bandwidth part (BWP) and have different channel numerologies The base station determines a guard band interval between the first DL channel and the second DL channel based on one or more characteristics of the different channel numerologies, transmits DL transmissions to the UE, over the first DL channel and the second DL channel, using the guard band interval between the first DL channel and the second DL channel.

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.

Abstract: An approach is described for a method for a base station in a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.
