1. A method, comprising:
transmitting, by network equipment comprising a processor, to a user equipment, first scheduling parameters for a physical uplink shared channel, wherein the first scheduling parameters are based on first channel state information estimated based on sounding reference signals received from the user equipment based on a first periodicity applicable to transmission of the sounding reference signals; and
in response to identifying, based on second channel state information estimated based on data received from the user equipment via the physical uplink shared channel, that second scheduling parameters for the physical uplink shared channel are able to be determined prior to subsequent sounding reference signals being transmitted by the user equipment based on the first periodicity, transmitting, by the network equipment, to the user equipment, a message that configures the user equipment to employ a second periodicity applicable to transmission of the subsequent sounding reference signals that is longer than the first periodicity.
