Abstract
An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources. The procedure may include specifying input parameter values pertaining to intended wireless communications of the device, adjusting output parameter values based on the input parameter values and an access history of the device, and determining whether to access at least a portion of the wireless communication resources to conduct the wireless communications, based at least on the output parameter values. The output parameter values may pertain to wireless communication resources accessible to the device, and the access history may keep track of wireless communication resource accesses previously made by the device. Input parameter values may include requested channel occupation time, requested frequency resource, requested transmission power, and/or priority and/or urgency of requested transmission, while output parameter values may include energy detection threshold, contention window size, and/or extended clear channel assessment bypass.
