SPATIAL REUSE BASED ON DISTRIBUTED REPORTING

摘要

The embodiments provide a method implemented by a network device in a wireless local area network (WLAN) that improves efficiency for clear channel assessment (CCA) in the WLAN. The network device processes information announced by other network devices in the WLAN and uses this information to determine a CCA regime to be used in a basic service set (BSS) associated with the network device. The method encodes an outgoing frame with an indication of the CCA regime to be used in the BSS and transmits the outgoing frame through a wireless medium.

主权项

1. A method executed by a network device in a wireless local area network (WLAN) to improve efficiency for clear channel assessment (CCA) in the WLAN, the method comprising:
encoding an outgoing frame with an indication of a CCA threshold value to be used in a basic service set (BSS) associated with the network device, wherein the CCA threshold value indicated in the outgoing frame indicates a CCA threshold level used by all devices in the BSS to assess availability of a wireless medium upon which all the devices in the BSS are operating; determining that the wireless medium is idle based on the CCA threshold value; and transmitting the outgoing frame through the wireless medium upon determining that the wireless medium is idle.
