Techniques for reservation preamble for prioritized medium contention in a new radio shared spectrum communication system

An apparatus for wireless communications, comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• receive, on a preamble timeslot assigned to a first operator from a first network entity, a downlink reservation preamble;
• receive an indication including a number of operators from the first network entity;
• determine a transmission opportunity structure of an uplink reservation preamble including a starting location of a transmission opportunity including one or more listen-before-talk time slots based on the number of operators from the first network entity;
• and
• transmit, within the preamble timeslot assigned to the first operator and subsequent to a reception of the downlink reservation preamble, the uplink reservation preamble of the first operator to a second network entity.

A non-transitory computer-readable medium storing computer code executable by a processor for wireless communication by a user equipment (UE), comprising code for:

• receiving, on a preamble timeslot assigned to a first operator from a first network entity, a downlink reservation preamble;
• receiving an indication including a number of operators from the first network entity;
• determining a transmission opportunity structure of an uplink reservation preamble including a starting location of a transmission opportunity including one or more listen-before-talk time slots based on the number of operators from the first network entity;
• and
• transmitting, within the preamble timeslot assigned to the first operator and subsequent to the receiving of the downlink reservation preamble, the uplink reservation preamble of the first operator to a second network entity.
