Channel reservation transmission schemes in shared radio frequency spectrum

A method for wireless communication, comprising:

• identifying that a base station is transmitting a first transmission on a channel in a shared radio frequency spectrum band;
• receiving a channel reservation signal from the base station;
• and
• identifying a time duration that the channel is to be occupied by the first transmission based at least in part on a payload of the channel reservation signal.

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:
• perform a listen before talk (LBT) procedure to identify that a channel in a shared radio frequency spectrum band is available for a first transmission;
• identify a time duration that the channel is to be occupied by the first transmission;
• generate a channel reservation signal having a payload that indicates the time duration;
• and
• transmit the channel reservation signal.
