Abstract

A BSS to which a destination wireless communication apparatus of a physical layer frame belongs is identified, and accuracy of preamble detection is improved by changing a reception operation. A wireless communication apparatus includes a reception unit that detects a frame including information for identifying a BSS, and a control unit that switches between a first operation in a case where the frame is a frame which is associated with a BSS to which the wireless communication apparatus belongs and a second operation in a case where the frame is a frame which is not associated with the BSS to which the wireless communication apparatus belongs. Carrier sensing is not performed in the first operation, and the carrier sensing is performed in the second operation.

Claims2

Dependent claims

A wireless communication apparatus comprising:

reception circuitry configured to detect a frame including first information for identifying a Basic Service Set (BSS) and second information for indicating a duration;
a determination circuitry configured to, based on the first information, determine whether the frame is associated with a BSS to which the wireless communication apparatus belongs;
and
control circuitry configured to configure a first operation in a case that the frame is associated with the BSS to which the wireless communication apparatus belongs, and a second operation in a case that the frame is not associated with the BSS to which the wireless communication apparatus belongs,
wherein a first network allocation vector (NAV) associated with the duration is set in the first operation,
a second NAV associated with the duration is set in the second operation, and
each of the first NAV and the second NAV is set individually.
