Transmission opportunity (txop) structure for new radio-unlicensed (nr-u) and new radio-synchronized sharing (nr-ss)

An apparatus comprising:

• a transceiver configured to:
• communicate, with a first wireless communication device during a reservation period, a channel reservation request for a first transmission opportunity (TXOP) in a spectrum;
• communicate, with the first wireless communication device during a response period in response to the channel reservation request, a channel reservation response;
• and
• communicate, with a second wireless communication device during a first time period between the reservation period and the response period, a first communication signal.

A computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to communicate, with a second wireless communication device during a reservation period, a channel reservation request for a first transmission opportunity (TXOP) in a spectrum;
• code for causing the first wireless communication device to communicate, with the second wireless communication device during a response period in response to the channel reservation request, a channel reservation response;
• and
• code for causing the first wireless communication device to communicate, with a third wireless communication device during a first time period between the reservation period and the response period, a first communication signal.
