Abstract
This disclosure provides methods, components, devices and systems for backoff periods. In some approaches, channel access for wireless devices may be prioritized. For example, some types of data traffic or wireless devices may have associated priorities, and channel access may be managed based on the associated priorities. In some approaches, a wireless device may utilize a backoff value associated with a priority to manage a backoff period. In some approaches, a randomized backoff may be utilized based on a random value within a random range and an offset value. For example, a random backoff may be increased in a case that a threshold quantity of collisions occurred at a deterministic backoff node. A fixed block size offset may be added to the random backoff.

A first wireless device, comprising:
- one or more memories storing processor-executable code;
- and
- one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first wireless device to:
- monitor a wireless channel during a first deterministic backoff period to identify a first quantity of zero or more interrupting signals;
- transmit, after the first deterministic backoff period, a first signal, the first signal followed by a second deterministic backoff period that is based at least in part on the first quantity of the zero or more interrupting signals and a first backoff value associated with a first priority,
- wherein the first backoff value is based at least in part on a default backoff value, the default backoff value being associated with a default priority;
- and
- transmit a second signal after the second deterministic backoff period.
A first wireless device, comprising:
- one or more memories storing processor-executable code;
- and
- one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first wireless device to:
- monitor a wireless channel to detect a collision pattern;
- transmit a first signal after a randomized backoff period in response to detecting the collision pattern, the randomized backoff period being based at least in part on a random value within a random range and an offset value;
- monitor the wireless channel during a first deterministic backoff period after the first signal to identify a first quantity of zero or more interrupting signals;
- transmit, after the first deterministic backoff period, a second signal, the second signal followed by a second deterministic backoff period that is based at least in part on the first quantity of the zero or more interrupting signals and a first backoff value;
- and
- transmit a third signal after the second deterministic backoff period.
