Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may identify one or more candidate beams that have a better channel metric than a serving beam. The UE may initiate a beam switch measurement counter, and perform one or more measurements on the identified candidate beams. In the event that one of the candidate beams is better than the serving beam for each measurement of the one or more measurements, the UE may perform a beam switch procedure to switch from the serving beam to the candidate beam.

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: Sensor assisted beam management system and methods for mobile User Equipment (UEs) are disclosed. An embedded rotation sensor may be used to determine orientation, rotating direction and angular speed of the UE. A speed sensor and GPS may also be used to determine location, moving direction and speed of the UE. The sensor outputs may be used by the UE to efficiently select UE beams after movement or to predict when a UE beam should be updated. Beam search and measurement periodicities may also be updated based on UE movements reported by the sensors.

Abstract: Dynamic User Equipment (UE) beam switching for millimeter wave (mmWave) measurements in asynchronous networks is discussed in which a UE configured with a plurality of UE beams receives timing information of detected cells in an asynchronous network, and calculates, based on the timing information, a maximum offset for the detected cells indicating a timing difference between a pair of cells of the detected cells that is larger than a timing difference between any other pair of the detected cells. A UE beam switch from a UE beam to another UE beam of the plurality of beams is scheduled based on the maximum offset, which includes using the maximum offset to determine how often the UE beam switch can be performed. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a signal-to-noise ratio (SNR) associated with the UE. The UE may determine a beam tracking frequency based at least in part on the SNR. The UE may perform a beam tracking in accordance with the beam tracking frequency. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling component carriers and one or more operations on a per NB RF chain basis. A method that may be performed by a user equipment (UE) includes monitoring occurrences of a first number of operations to be performed for a plurality of component carriers (CCs) according to different periodicities, determining a second number of available narrow band (NB) radio frequency (RF) chains, and scheduling, on the available NB RF chains, up to the second number of the operations to be performed for the plurality of CCs based on a scheduling algorithm if the first number is greater than the second number.

Abstract: A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.

Abstract: Aspects described herein relate to receiving, from a base station, a transmit beam including a synchronization signal block (SSB) of multiple broadcast signals transmitted over multiple symbols, wherein receiving the transmit beam includes switching among multiple receive beams for each of the multiple symbols to receive a corresponding broadcast signal of the multiple broadcast signals, measuring a signal metric of each of the multiple broadcast signals as received via a corresponding receive beam of the multiple receive beams in a corresponding symbol of the multiple symbols, and selecting, based on the signal metric measured for each of the multiple broadcast signals, a receive beam of the multiple receive beams for communicating with the base station.

Abstract: Certain aspects of the present disclosure provides a method for wireless communication at a user equipment (UE). In certain aspects, the method includes selecting, for each of a plurality of synchronization signal blocks (SSBs) of a synchronization signal (SS) burst set, one corresponding receive beam of a plurality of receive beams of the UE. In certain aspects, the method also includes monitoring, at each of the plurality of SSBs, for at least one synchronization signal transmitted by at least one base station (BS) using the corresponding selected receive beam.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.
