Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message including a first indication for updating a beam for communicating with the base station to a first beam and a second indication for configuring a set of reference signals for measuring the first beam. The UE may measure the first beam using the reference signals. The UE may communicate with the base station based on the beam measurement. The control message may include a format for jointly indicating beam updates and reference signal configurations.

A method for wireless communication at a user equipment (UE), comprising:
- receiving, from a base station, a control message comprising a first indication for updating a beam for communicating with the base station to a first beam and a second indication for configuring a set of reference signals for measuring the first beam;
- measuring the first beam using the set of reference signals;
- and
- communicating with the base station using the first beam based at least in part on the measuring.
A method for wireless communication at a base station, comprising:
- transmitting, to a user equipment (UE), a control message comprising a first indication for updating a beam for communicating with the UE to a first beam and a second indication for configuring a set of reference signals for the UE measuring the first beam;
- transmitting the set of reference signals based at least in part on the second indication;
- and
- communicating with the UE using the first beam.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive, from a base station, a control message comprising a first indication for updating a beam for communicating with the base station to a first beam and a second indication for configuring a set of reference signals for measuring the first beam;
- measure the first beam using the set of reference signals;
- and
- communicate with the base station using the first beam based at least in part on the measuring.
