A base station may transmit an indication of first and second configurations for sounding reference signal (SRS) transmissions during first and second transmission time intervals (TTIs) having different durations. A user equipment (UE) may identify an SRS to be transmitted and determine a configuration for the SRS transmission based on the TTI duration and the received indication of the first and second configurations. The UE may then transmit the SRS based on the configuration. A base station may receive an SRS during a TTI and may determine a channel quality based at least in part on the SRS. Additionally, a device may identify data to transmit during a TTI, determine a number of resource elements available for transmission of the data during a TTI, and determine a transport block size (TBS) for the data transmission based on the available resource elements.
