Dwell time based channel contention in wireless communications

A method for wireless communications, comprising:

• gaining channel access to a wireless channel in a shared radio frequency spectrum based at least in part on a first listen before talk procedure that indicates the wireless channel is unused by one or more other transmitters, wherein the first listen before talk procedure provides the channel access for a maximum channel occupancy time duration;
• transmitting, responsive to gaining the channel access, a first communication to one or more receiving devices via the wireless channel during the maximum channel occupancy time duration;
• discontinuing transmitting via the wireless channel subsequent to the first communication for at least a duration of a transmission gap;
• determining that the transmission gap is less than a threshold transmission gap duration;
• and
• transmitting, subsequent to the transmission gap and in an absence of a second listen before talk procedure, a second communication to the one or more receiving devices during the maximum channel occupancy time duration;
• wherein the second communication is transmitted in the absence of the second listen before talk procedure responsive to the transmission gap being less than the threshold transmission gap duration.

An apparatus for wireless communications, comprising:

• means for gaining channel access to a wireless channel in a shared radio frequency spectrum based at least in part on a first listen before talk procedure that indicates the wireless channel is unused by one or more other transmitters, wherein the first listen before talk procedure provides the channel access for a maximum channel occupancy time duration;
• means for transmitting, responsive to gaining the channel access, a first communication to one or more receiving devices via the wireless channel during the maximum channel occupancy time duration;
• means for discontinuing transmitting via the wireless channel subsequent to the first communication for at least a duration of a transmission gap;
• means for determining that the transmission gap is less than a threshold transmission gap duration;
• and
• means for transmitting, subsequent to the transmission gap and in an absence of a second listen before talk procedure, a second communication to the one or more receiving devices during the maximum channel occupancy time duration;
• wherein the second communication is transmitted in the absence of the second listen before talk procedure responsive to the transmission gap being less than the threshold transmission gap duration.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by a processor to:

• gain channel access to a wireless channel in a shared radio frequency spectrum based at least in part on a first listen before talk procedure that indicates the wireless channel is unused by one or more other transmitters, wherein the first listen before talk procedure provides the channel access for a maximum channel occupancy time duration;
• transmit, responsive to gaining the channel access, a first communication to one or more receiving devices via the wireless channel during the maximum channel occupancy time duration;
• discontinue transmitting via the wireless channel subsequent to the first communication for at least a duration of a transmission gap;
• determine that the transmission gap is less than a threshold transmission gap duration;
• and
• transmit, subsequent to the transmission gap and in an absence of a second listen before talk procedure, a second communication to the one or more receiving devices during the maximum channel occupancy time duration;
• wherein the second communication is transmitted in the absence of the second listen before talk procedure responsive to the transmission gap being less than the threshold transmission gap duration.
