Abstract
Techniques are described for wireless communication at a wireless communication device. One method includes determining an availability of a sub-band of a shared radio frequency spectrum band during a first portion of a distributed channel availability check (CAC); receiving at least one indication that the sub-band is available during remaining portions of the distributed CAC; and communicating over the sub-band based at least in part on determining the sub-band is available during the first portion of the distributed CAC and the at least one indication that the sub-band is available during remaining portions of the distributed CAC.

A method for wireless communication at a wireless device, comprising:
- determining an availability of a sub-band of a shared radio frequency spectrum band during a first portion of a distributed channel availability check (CAC);
- receiving at least one indication that the sub-band is available during remaining portions of the distributed CAC;
- and
- communicating over the sub-band based at least in part on determining the sub-band is available during the first portion of the distributed CAC and the at least one indication that the sub-band is available during remaining portions of the distributed CAC.
A method for wireless communication, comprising:
- assigning a first portion of a distributed channel availability check (CAC) to a first wireless device of a plurality of wireless devices, the distributed CAC associated with a sub-band of a shared radio frequency spectrum band;
- communicating the assignment of the first portion of the distributed CAC to the first wireless device;
- and
- communicating over the sub-band based at least in part on receiving an indication the sub-band is determined available during the first portion of the distributed CAC and determining the sub-band is available during remaining portions of the distributed CAC.
An apparatus for wireless communication, comprising:
- a processor;
- and
- memory in electronic communication with the processor;
- the processor and the memory configured to:
- determine an availability of a sub-band of a shared radio frequency spectrum band during a first portion of a distributed channel availability check (CAC);
- receive at least one indication that the sub-band is available during remaining portions of the distributed CAC;
- and
- communicate over the sub-band based at least in part on determining the sub-band is available during the first portion of the distributed CAC and the at least one indication that the sub-band is available during remaining portions of the distributed CAC.
