Abstract: A UE is configured to determine a set of parameters associated with receiving the SSBs, the set of parameters including a first parameter bitmap associated with a serving cell, a second parameter bitmap associated with the neighbor cell, and the SMTC. The UE is configured to determine a search window for searching the received SSBs based on the SMTC and at least one of the first parameter bitmap or the second parameter bitmap. The UE may measure the SSBs searched during the determined search window and send measurement results associated with at least a subset of the measured SSBs to the base station. The UE may also prune measurements to generate the measurement results by removing measurements associated with SSBs received in slots that are not indicated to expect SSBs, based on the first parameter bitmap, the second first parameter bitmap, or the SMTC.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for applying a zero element beam to conserve power in search and measurement operations of a UE. The UE may determine to measure a set of SSBs, where each SSB of the set of SSBs is transmitted on four symbols, and further determine a subset of the SSBs for which less than the four symbols associated with the SSBs are to be used for measurement of the SSBs. The UE may measure each SSB of the subset of the SSBs through less than the four symbols associated with the SSB.

Abstract: Certain aspects of the present disclosure provide techniques for beam failure detection and recovery. A method that may be performed by a user equipment (UE) includes monitoring one or more first reference signals to detect a beam failure for one or more first control resource sets (CORESETs), transmitting an indication of the beam failure, and receiving a beam failure response after the transmission of the indication of the beam failure, wherein the monitoring of the one or more first reference signals for the detection of the beam failure stops in response to the reception of the beam failure response. The UE may then receive a configuration message after the reception of the beam failure response, and monitor, in response to the reception of the configuration message, one or more second reference signals to detect another beam failure for one or more second CORESETs.

Abstract: Certain aspects of the present disclosure relate to a method and apparatus for wireless communications by a user equipment (UE) having at least two radio frequency (RF) chains and capable of communicating with first and second radio access networks (RANs). In aspects, the UE may utilize both RF chains to measure signals in the first RAN, during a first measurement period, while on the second RAN. The UE may determine signal conditions in the first RAN, based on the measurements, and decide, based on the determined signal conditions, which of the RF chains to use to measure signals in the first RAN during one or more subsequent measurement periods.
Abstract translation: 本公开的某些方面涉及用于具有至少两个射频（RF）链并且能够与第一和第二无线电接入网络（RAN）通信的用户设备（UE）进行无线通信的方法和装置。 在方面中，UE可以在第一测量周期期间同时使用RF链来测量第一RAN中的信号，而在第二RAN上。 UE可以基于测量来确定第一RAN中的信号状况，并且基于确定的信号条件来确定在一个或多个后续测量周期期间使用哪个RF链来测量第一RAN中的信号。

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: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

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.
