Abstract: Some embodiments include systems, apparatuses, methods, and computer-readable media for use in a wireless network for determining a reception (Rx) beam sweep scale factor, N, that enables a user equipment (UE) to perform Rx beam refinement. Some embodiments are directed to a 5G Node B (gNB) that includes processor circuitry and radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, a MaxNumberRxB cam capability of the UE. The processor circuitry can determine based at least on the MaxNumberRxBeam capability of the UE and/or a Channel-State Information (CSI)-reference signal (RS) set with a repetition parameter configured to be ON, the value of N. The processor circuitry can generate a message comprising the value N, and encode the message for transmission to the UE, where N Rx beam sweeps enable the UE to perform Rx beam refinement.

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: Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

Abstract: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

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 user equipment (UE) that includes radio front end circuitry and processor circuitry. The front end circuitry receives an indication from a network entity node, wherein the indication is indicative of a first fraction for a first radio resource management (RRM) procedure and a second fraction for a second RRM procedure. The processor circuitry performs a first measurement of the first RRM procedure in a first fraction of a measurement period. The processor circuitry further performs a second measurement of the second RRM procedure in a second evaluation period, wherein the second evaluation period is the second fraction of the measurement period.
