Methods, systems, and devices for wireless communication are described. In some wireless communication systems, a user equipment (UE) may receive control signaling from a base station based on an uplink beam failure. The control signaling may indicate one or more uplink beams for uplink communications, and the one or more uplink beams may be decoupled from a downlink beam for downlink communications by the UE. The UE may transmit a feedback message acknowledging the one or more uplink beams for the uplink communications based on receiving the control signaling. The UE may switch from one or more current uplink beams to the one or more uplink beams indicated via the control signaling during a time period after receiving the control signaling. The UE may transmit the uplink communications using the one or more uplink beams based on the feedback message.

A method of operating a communications device for communicating data via a wireless communications network comprises detecting one or more of a plurality of beams of radio signals transmitted by the wireless communications network. The method comprises determining whether a received signal strength of the radio signals of each of the one or more beams exceeds a first evaluation threshold, identifying a sub-set of the set of detected beams of radio signals which can be used to receive data carried by the radio signals of the beam for which the received signal strength exceeds the first evaluation threshold, and entering a relaxed radio measurement state in which the communications device reduces an amount of attempted measurements of the plurality of beams of radio signals compared with a normal state according to one or more relaxed measurement state criteria.

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating a set of sampling beams defined for the UE. The UE may measure a set of received signal strengths for communications from a wireless node associated with a set of linear combinations of sampling beams from the set of sampling beams defined at the UE. The UE may calculate a set of entries of a channel covariance matrix based on the set of received signal strengths of the set of linear combinations of the sampling beams from the set of sampling beams defined for the UE. As such, the UE may communicate with the wireless node based on applying a set of beam weights to an antenna array of the UE. In some examples, the set of beam weights may be based on the channel covariance matrix.
