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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a change of one or more reception conditions. The UE may transmit, to a base station and based at least in part on the change of the one or more reception conditions, a request for a radio link adaptation operation to update one or more of a reception beam or a transmission beam of the base station used to communicate with the UE. Numerous other aspects are described.

Abstract: A first wireless device may select a first beam for communication with a second wireless device from a first set of beams associated with a first beam level. A second set of beams may be associated with a second beam level. The first beam may be associated with a first children list. The first children list may be associated with a first subset of beams of the second set of beams. Each beam in the first subset of beams may have an envelope area that intersects an envelope area of the first beam. The first wireless device may select a second beam for communication with the second wireless device from the first subset of beams based on an envelope area of the second beam intersecting the envelope area of the first beam. The first wireless device may communicate with the second wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate, from an energy of the UE, a first amount of energy to a first communication link and a second amount of energy to a second communication link. The UE may identify a first energy request associated with the first communication link of the UE and a second energy request associated with the second communication link of the UE. The UE may allocate, from a remainder of the energy after the first amount of energy and the second amount of energy are allocated, a third amount of energy to the first communication link and a fourth amount of energy to the second communication link. The UE may transmit in accordance with the third amount of energy or the fourth amount of energy. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may measure a beam, according to a measurement configuration, to determine a channel condition value of the beam, modify the channel condition value based at least in part on at least one of one or more beam characterizations, a derivation of a beamforming gain value, or an estimation of the beamforming gain value, and transmit, to a base station, a measurement report indicating the modified channel condition value. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a single layer reference signal. The UE may perform single layer measurements associated with the single layer reference signal for a plurality of UE beam pairs. The UE may determine, based at least in part on the single layer measurements for the plurality of UE beam pairs, multiple layer measurements associated with one or more UE beam pairs of the plurality of UE beam pairs. The UE may select, from the one or more UE beam pairs, a UE beam pair based at least in part on the multiple layer measurements associated with the one or more UE beam pairs. Numerous other aspects are described.

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.
