1. An apparatus for wireless communication at a user equipment (UE), comprising:
one or more processors;
one or more memories coupled with the one or more processors; and
instructions stored in at least one of the one or more memories and executable by the one or more processors, individually or collectively, to cause the apparatus to:
receive, from a network entity, radio resource control signaling that configures one or more sounding reference signal resources for transmitting a sounding reference signal to the network entity;
receive, from the network entity, a medium-access-control control element that indicates a set of one or more available spatial relations for transmitting the sounding reference signal to the network entity, the medium-access-control control element indicating a first sounding reference signal resource of the one or more sounding reference signal resources and a first spatial relation of the set of one or more available spatial relations to be used for the sounding reference signal, the first spatial relation indicating at least one of a synchronization signal block index, a channel state information reference signal resource index, or a sounding reference signal resource index; and
transmit the sounding reference signal to the network entity using one or more uplink transmission parameters indicated in the first spatial relation.
