Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a beam recovery or beam tracking message to the base station using at least one of a resource or a waveform selected based at least in part on the selected DL beam.

A method for wireless communication at a user equipment (UE), comprising:
- receiving a downlink (DL) signal from a base station on one or more DL beams;
- identifying a selected DL beam of the one or more DL beams for communications from the base station to the UE;
- selecting at least one of a resource or a waveform for a beam recovery or beam tracking message based at least in part on the selected DL beam of the one or more DL beams;
- and
- transmitting the beam recovery or beam tracking message to the base station using at least one of the resource or the waveform selected based at least in part on the selected DL beam.
A method for wireless communication at a base station, comprising:
- transmitting a downlink (DL) signal on one or more DL beams;
- receiving, on at least one of a resource or a waveform, a beam recovery or beam tracking message from a user equipment (UE);
- identifying, based at least in part on the resource or the waveform, a selected DL beam of the one or more DL beams for communications from the base station to the UE;
- and
- transmitting one or more subsequent messages to the UE using the selected DL beam.
