Fairness in Clear Channel Assessment Under Long Sensing Time

摘要

Mechanisms for clear channel assessment associated with a communication channel in a wireless environment are provided. Implementation of the mechanisms provides fairness in the utilization of wireless communication resources among contemporaneous communication devices and legacy communication devices. The communication channel can be embodied in a primary channel or a secondary channel according to communication protocols within the IEEE 802.11 family of protocols.

1. At least one computer-readable non-transitory storage medium having instructions stored thereon that, when executed by one or more processors of a communication device, direct the one or more processors to perform operations comprising:
determining a sensing interval associated with performing a clear channel assessment in a communication channel; determining an interframe spacing associated with a defined frame; detecting via the clear channel assessment, using the sensing interval, that a signal is present in the communication channel; and
determining that the sensing interval overlaps a backoff period by the defined number of backoff slots, andincreasing a backoff counter by the defined number of backoff slots.
