1. A method for wireless communication, comprising:
identifying a level of accuracy for a channel estimation to be performed by a base station, the channel estimation associated with at least one communication with the base station;
determining a quantity of sounding reference signals (SRSs) for transmitting during a transmission time interval (TTI) based at least in part on the level of accuracy for the channel estimation;
assigning a plurality of symbols within a repetition window of the TTI, wherein the repetition window indicates a number of symbols used for transmitting the quantity of SRSs, and wherein assigning the plurality of symbols is based at least in part on determining the quantity of SRSs and on the level of accuracy for the channel estimation; and
transmitting the quantity of SRSs in the TTI based at least in part on assigning the plurality of symbols.
