Self-contained uplink for reduced duration transmission time interval

A method of wireless communication comprising:

• transmitting an uplink resource allocation that is associated with a two-symbol transmission time interval (TTI);
• determining whether a demodulation reference signal (DM-RS) is scheduled to be transmitted in one symbol of the two-symbol TTI as part of the uplink resource allocation;
• and
• receiving data or the DM-RS, or both, during the two-symbol TTI based at least in part on the determination of whether the DM-RS is scheduled.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive an uplink resource allocation that is associated with a two-symbol transmission time interval (TTI);
• determine whether a demodulation reference signal (DM-RS) is scheduled to be transmitted in one symbol of the two-symbol TTI as part of the uplink resource allocation;
• and
• transmit data or the DM-RS, or both, during the two-symbol TTI based at least in part on the determination of whether the DM-RS is scheduled.
