1. A communication method of a wireless local area network (LAN) base station configured to perform uplink multi-user communication with a plurality of wireless LAN terminals, whereinan association identifier (AID) indicating an associated wireless LAN terminal includes a specific bit generated by using a basic service set (BSS) color bit (BCB), and
the communication method comprises:
generating an unassociation identifier (UAID) indicating an unassociated wireless LAN terminal, in order to include the specific bit or a processed bit obtained by processing the specific bit; and
using a bit to be distinguished from the AID as a bit other than the specific bit of the UAID in a case where the specific bit is included in the UAID.
