Synchronous shared spectrum

A method for wireless communications at a base station associated with a first network operator, comprising:

• determining a prioritization of the first network operator for a first transmission opportunity and a second transmission opportunity, wherein the first network operator is higher priority than a second network operator during the first transmission opportunity and the second network operator is higher priority than the first network operator during the second transmission opportunity;
• transmitting a tentative grant to a user equipment (UE) over a channel of a shared radio frequency spectrum band using resources within the first transmission opportunity associated with tentative grants based at least in part on the determined prioritization, wherein the tentative grant schedules an uplink data transmission using the channel over a set of resources of the second transmission opportunity subsequent to the first transmission opportunity;
• and
• monitoring the set of resources of the second transmission opportunity for the uplink data transmission from the UE.

A method for wireless communications at a user equipment (UE), comprising:

• receiving a tentative grant from a base station associated with a first network operator over a channel of a shared radio frequency spectrum band using resources within a first transmission opportunity associated with tentative grants, wherein the tentative grant schedules an uplink data transmission using the channel over a set of resources of a second transmission opportunity subsequent to the first transmission opportunity;
• monitoring, during a contention window of the second transmission opportunity, for one or more contention messages from a device associated with a second network operator;
• and
• performing the uplink data transmission based at least in part on the tentative grant and a result of the monitoring.
