Abstract: A UE may identify a channel correlation matrix for a channel between the UE and a network node. The UE may identify whether the channel is associated with an LOS condition based on the channel correlation matrix. The UE may obtain a plurality of eigenvalues of the channel correlation matrix based on an eigen decomposition operation on the channel correlation matrix. The UE may identify whether the channel is associated with the LOS condition based on the plurality of eigenvalues of the channel correlation matrix. The UE may identify that the channel is associated with the LOS condition if a difference between a greatest eigenvalue in the plurality of eigenvalues and an average of other eigenvalues in the plurality of eigenvalues is greater than a threshold. Otherwise, the UE may identify that the channel is not associated with the LOS condition.

Abstract: Disclosed are techniques for wireless communication. In an aspect, during a first synchronization wakeup period while RF circuitry and the FW circuitry are set to an active state, one or more measurements of one or more SSBs of a first SSBS from a base station. The UE predicts, during the first synchronization wakeup period while the RF circuitry and the FW circuitry are in the active state, a second SSBS at which to wake up for a second synchronization wakeup period based on the one or more measurements. In response to completion of FW post-processing operations, the UE transitions the RF circuitry and the FW circuitry from the active state to a sleep state.

Abstract: Wireless communications systems and methods related to monitoring and/or measuring synchronization signal blocks (SSBs) in one or more beam directions based on timing offsets associated with the beam directions are provided. In some aspects, a method of wireless communication performed by a user equipment (UE) includes: receiving, from a wireless communication device, a synchronization signal block (SSB); and measuring, based on timing offsets for each of a plurality of beams of the SSB, one or multiple beams of the SSB. In some instances, the UE determines a number of beams of the SSB to measure based on the timing offsets for each of the plurality of beams of the SSB.

Abstract: Certain aspects of the present disclosure provide techniques for adapting search, measurement, and loop tracking periodicities in new radio communications. A method that may be performed by a user equipment (UE) includes determining, based on one or more parameters, a first periodicity to perform a search to detect one or more component carriers (CCs), cells, beams, or a combination thereof; a second periodicity to perform measurement of one or more cells, beams, or both in one more detected CCs; and a third periodicity to perform loop tracking to monitor a downlink serving quality, an uplink serving beam quality, or both of a cell. The method may further includes performing the search at the determined first periodicity, measurement at the determined second periodicity, and loop tracking at the determined third periodicity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more receive beams, a channel state information reference signal (CSI-RS) transmitted on a transmit beam of the CSI-RS according to a beam management configuration for periodic CSI-RSs, where the UE performs measurements according to a static beam sweeping schedule or a dynamic beam sweeping schedule associated with the transmit beam of the CSI-RS based at least in part on the beam management configuration. In some aspects, the UE may transmit a measurement report indicating one or more measurements of the CSI-RS based at least in part on measuring the CSI-RS. Numerous other aspects are provided.

Abstract: A UE may be configured to select narrower or wider beams that may be suitable for use with a current UE mobility, scattering environment, etc. The UE may track changes to an identified beam of a certain width, and so may recover from tracking or other radio link failures by switching to a beam that is spatially adjacent or to a beam of a different width. The UE may identify a first beam associated with a first beam width based on at least one reference signal received by the UE. The UE may further determine a set of beams based on the first beam width that is associated with the identified first beam, and the determined set of beams may include at least one beam corresponding to the first beam width. The UE may further measure respective channel qualities associated with each beam of the determined set of beams.
