Methods and apparatus for clear channel assessment

摘要

Systems and methods of clear channel assessment on a wireless network are disclosed. In one aspect, a method includes determining a clear channel assessment (CCA) threshold based on a first transmission bandwidth, performing a first back-off procedure based on the determined clear channel assessment threshold; and transmitting a first wireless message in response to a completion of the first back-off procedure.

主权项

1. A method of clear channel assessment on a wireless network, comprising:
determining, by an electronic device, a first transmission bandwidth for a first wireless message; determining, by the electronic device, a clear channel assessment (CCA) threshold based on the first transmission bandwidth for the first wireless message; performing, by the electronic device, a first back-off procedure based on the determined clear channel assessment threshold to determine if the first transmission bandwidth is available for transmission of the first wireless message, wherein the first back-off procedure comprises performing at least two sub-back-off procedures at least partially in parallel, each sub-back-off procedure utilizing a different frequency range to detect energy or to detect a packet; and transmitting, by the electronic device, the first wireless message over the first transmission bandwidth in response to a completion of the first back-off procedure.
