Techniques for adjusting clear channel assessment (CCA) window for transmissions in a shared radio frequency spectrum band

An apparatus for wireless communications, comprising:

• a processor;
• memory coupled to the processor;
• and
• the processor and memory configured to:
• determine a feedback parameter associated with a first transmission;
• determine a contention window adjustment value based at least in part on the feedback parameter, wherein determining the contention window adjustment value comprises weighting a non-reported acknowledgement as a reported negative acknowledgment (NACK);
• and
• adjust a contention window size for a second transmission based at least in part on the contention window adjustment value.

An apparatus for wireless communications comprising:

• means for determining a feedback parameter associated with a first transmission;
• means for determining a contention window adjustment value based at least in part on the feedback parameter, wherein determining the contention window adjustment value comprises weighting a non-reported acknowledgement as a reported negative acknowledgment (NACK);
• and
• means for adjusting a contention window size for a second transmission based at least in part on the contention window adjustment value.

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

• determine a feedback parameter associated with a first transmission;
• determine a contention window adjustment value based at least in part on the feedback parameter, wherein determining the contention window adjustment value comprises weighting a non-reported acknowledgement as a reported negative acknowledgment (NACK);
• and
• adjust a contention window size for a second transmission based at least in part on the contention window adjustment value.
