Abstract: Certain aspects of the present disclosure provide techniques for cell measurement scheduling mode selection. According to certain aspects, a method for wireless communications by a user equipment (UE), generally includes selecting a first scheduling mode for performing cell measurements while the UE is in an idle state, in response to detecting at least one first triggering condition based on a comparison of a serving cell measurement to one or more neighbor cell measurements and performing cell measurements in accordance with the first scheduling mode, wherein the UE performs cell measurement more frequently when the first scheduling mode is selected than when a second scheduling mode is selected.

Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

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.
