Abstract

An Access Point (AP) and a wireless device, as well as complementary methods performed by the AP and the wireless device for communication with each other, are provided. Embodiments of the AP-performed method can include determining one or more Clear Channel Assessment Thresholds (CCATs) for data to be transmitted to the wireless device, wherein each CCAT is associated with a particular Quality of Service (QoS) category of the data. Such embodiments can also include determining whether the channel is busy or free based on the determined one or more CCATs and based on signals or energy detected on the channel and, based on determining that the channel is free, transmitting the data to the wireless device. In some embodiments, the data can be transmitted to the wireless device while further data is being transmitted on the channel.
