Abstract
A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV monitors for ongoing transmission(s) on a wireless communication medium before transmitting a signal to another WDEV via the wireless communication medium. The WDEV uses different threshold levels (and/or variable threshold level functions) based on whether a detected ongoing transmission is associated with a first or second wireless communication network to determine when to make a concurrent transmission. For example, different WDEVs are associated with different wireless communication networks, and the WDEV uses different considerations to determine when to make transmissions in different situations.
