Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. A wireless communication method for transmitting and receiving a frame using a channel by access control based on carrier sense multiple access with collision avoidance (CSMA/CA) using a clear channel assessment threshold (CCA threshold), wherein:
a format that includes a field for an identification of a basic service set (BSS) within a preamble of the frame is defined as an HE format;
said wireless communication method includes the steps of:
checking a destination station to which an HE format frame is scheduled to be transmitted;
controlling the CCA threshold to a value higher than a default value if the destination station is an HE station; and
transmitting the frame if the channel is determined to be idle by the CSMA/CA.
