Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for adaptively updating one or more parameters, such as power hysteresis, for determining whether beam switching should be performed. A user equipment (UE) may assess a first beam quality of a first beam for communications with a network entity and a second beam quality of a second beam. The UE adjusts a value of power hysteresis based on one or more conditions, such as whether the UE is mobile and/or the signal to noise ratio (SNR) of the first beam is less than a threshold. Based on the adjusted value of power hysteresis, the UE may switch from the first beam to the second beam if a difference between the second beam quality and the first beam quality is greater than the adjusted value of power hysteresis.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station and a user equipment (UE) may utilize multi-port reference signals to determine a beam pair for rank-2 transmissions. For example, a UE may receive a set of multi-port reference signals, where each multi-port reference signal of the set corresponds to a unique beam pair and is received via two ports associated with two different polarizations. The UE may determine a spectral efficiency estimation for each multi-port reference signal of the set, select a beam pair associated with a multi-port reference signal with the highest determined spectral efficiency estimation of the set, and transmit an indication of the selected beam pair to the base station. Therefore, the UE and the base station may communicate using a beam pair which maximizes the spectral efficiency and rate of rank-2 transmissions.
