Abstract: A base station may receive from a user equipment (UE) a proactive notification that the UE will perform a beam switch from a first UE beam to a second UE beam. In response, the base station may determine a beam switch slot on which the UE will perform the synchronized beam switch, and perform a link transient mitigation operation for communications with the UE after UE beam switch and until updating channel state information associated with a new UE beam. The base station may then receive from the UE channel state information feedback for a channel associated with the second UE beam, and adjust downlink data transmission parameters to be aligned with the second UE beam based on the received channel state information feedback (CSF). The base station may also adjust uplink data transmission parameters based on a sounding reference signal transmitted by the UE over the second UE beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, while camped on a first cell associated with a first radio access technology (RAT), a power management level for a communication using a second RAT, wherein the power management level indicates an available power for the communication using the second RAT, and wherein the available power is based at least in part on an exposure rate or an absorption rate. The UE may delay a transmission of a measurement report on the first cell based at least in part on the identification of the power management level. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a cell search using a first set of beams. The UE may determine a channel condition value based at least in part on performing the cell search. The UE may modify the channel condition value based at least in part on at least one of: the first set of beams used to perform the cell search, a beam selected from the first set of beams, or a second set of beams that is different from the first set of beams and that is included in a beamforming codebook associated with the UE. The UE may transmit a measurement report that includes the modified channel condition value. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a synchronization signal block (SSB)-level sleep mode. A method that may be performed by a user equipment (UE) includes determining, from a synchronization signal burst set, a first set of synchronization signal blocks (SSBs) to forgo performing measurements on using one or more receive beams based, at least in part, on one or more previous measurements associated with the determined first set of SSBs and performing measurements on only one or more remaining SSBs in the synchronization signal burst set using the one or more receive beams.

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: Aspects of the disclosure relate to devices, systems and methods for multi-beam formation. A user equipment (UE) may determine a sampling interval for references signals to be transmitted by a base station for an upcoming control or data communication. For example, the UE may determine a maximum sampling interval tolerable for channel estimation and select the sampling interval based on the maximum. In some examples, the UE determines the sampling interval based on characteristics of its motion. The UE transmits an indication of the sampling interval to the base station. Based on the indication, the base station selects an interval for the reference signals and transmits the reference signals to the UE to enable it to perform the channel estimation for the multi-beam. The base station may determine to select the interval for the reference signals such that it is less than or equal to the sampling interval indicated by the UE.

Abstract: Wireless communication devices are adapted to utilize maximum permissible exposure requirements in determining uplink traffic grant allocations within wireless communication systems. According to one example, a wireless communication device can determine one or more candidate uplink duty cycles for a subsequent uplink transmission interval based at least in part on an MPE requirement, determine a maximum number of resource blocks per symbol and a maximum MSC index associated with each of the one or more candidate uplink duty cycles from a predefined MCS index table, and select a duty cycle, number of resource blocks per symbol, and MCS that facilitates a largest number of un-coded bits for the subsequent uplink transmission interval. Other aspects, embodiments, and features are also included.
