Assignee: INTERNATIONAL SEMICONDUCTOR GROUP
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A wireless communication method performed in a wireless communication device comprising:
receiving a first frame addressed to a first wireless communication device other than the wireless communication device;
setting a first transmission prohibition period for a first network in response to determining that a sender of the first frame belongs to the first network to which the wireless communication device belongs based on the first frame;
setting a second transmission prohibition period for a second network in response to determining that the sender of the first frame belongs to the second network;
determining, when the receiver receives a second frame addressed to a second wireless communication device other than the wireless communication during a carrier-sensing in a period during which the first transmission prohibition period is not set and the second transmission prohibition period is set, and when a reception level of the second frame is a first threshold or more, whether a sender network of the second frame is the first network or the second network based on the second frame; and
comparing, in response to determining that the sender network is the second network, the reception level of the second frame with a second threshold greater than the first threshold to determine whether a state of a wireless medium is an idle state or a busy state.
