Flexible multiplexing and feedback for variable transmission time intervals

An apparatus for wireless communication comprising:

• means for identifying a downlink burst of a time-division duplex (TDD) configured carrier, the downlink burst comprising one or more downlink transmission time intervals (TTIs), wherein respective downlink TTIs of the one or more downlink TTIs have a variable duration;
• means for receiving respective indications of a duration of the respective one or more downlink TTIs, the respective indications received within a first control portion of each of the respective one or more downlink TTIs;
• means for receiving an indication of a duration of an uplink burst that follows the downlink burst, wherein the indication of the duration of the uplink burst is received within a second control portion of each of the respective one or more downlink TTIs, the second control portion being separated in time from the first control portion by a data portion of each of the respective one or more downlink TTIs;
• and
• means for communicating based at least in part on the respective indications of the duration of the respective one or more downlink TTIs and the indication of the duration of the uplink burst.

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:
• identify a downlink burst of a time-division duplex (TDD) configured carrier, the downlink burst comprising one or more downlink transmission time intervals (TTIs), wherein respective downlink TTIs of the one or more downlink TTIs have a variable duration;
• receive respective indications of a duration of the respective one or more downlink TTIs, the respective indications received within a first control portion of each of the respective one or more downlink TTIs;
• receive an indication of a duration of an uplink burst that follows the downlink burst, wherein the indication of the duration of the uplink burst is received within a second control portion of each of the respective one or more downlink TTIs, the second control portion being separated in time from the first control portion by a data portion of each of the respective one or more downlink TTIs;
• and
• communicate based at least in part on the respective indications of the duration of the respective one or more downlink TTIs and the indication of the duration of the uplink burst.

A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable to:

• identify a downlink burst of a time-division duplex (TDD) configured carrier, the downlink burst comprising one or more downlink transmission time intervals (TTIs), wherein respective downlink TTIs of the one or more downlink TTIs have a variable duration;
• receive respective indications of a duration of the respective one or more downlink TTIs, the respective indications received within a first control portion of each of the respective one or more downlink TTIs;
• receive an indication of a duration of an uplink burst that follows the downlink burst, wherein the indication of the duration of the uplink burst is received within a second control portion of each of the respective one or more downlink TTIs, the second control portion being separated in time from the first control portion by a data portion of each of the respective one or more downlink TTIs;
• and
• communicate based at least in part on the respective indications of the duration of the respective one or more downlink TTIs and the indication of the duration of the uplink burst.
