Techniques for using a portion of a transmission time interval to transmit a transmission that is shorter than a duration of the transmission time interval

A method of wireless communication at a wireless communication device, comprising:

• determining a portion of a transmission time interval (TTI) is available for a transmission that is shorter than a duration of the TTI;
• selecting a transmission format from a plurality of transmission formats for transmitting the transmission to a receiving device during the portion of the TTI;
• and
• transmitting the transmission to the receiving device.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and the processor and memory configured to:
• determine a portion of a transmission time interval (TTI) is available for a transmission that is shorter than a duration of the TTI;
• select a transmission format from a plurality of transmission formats for transmitting the transmission to a receiving device during the portion of the TTI;
• and
• transmit the transmission to the receiving device.

A method of wireless communication at a wireless communication device, comprising:

• receiving from a transmitting device, during a transmission time interval (TTI), a transmission that is shorter than a duration of the TTI;
• receiving, from the transmitting device, an indication of a timing of the transmission;
• and
• identifying the transmission based at least in part on the indication of the timing of the transmission.
