Abstract:
Methods, computer readable media, and wireless apparatuses are disclosed for setting network allocation vectors (NAV) for multi-user (MU) operation. An apparatus of a wireless device is disclosed. The apparatus comprising processing circuitry configured to: decode a preamble portion of a frame, and if the preamble portion of the frame comprises a high-efficiency (HE) signal (SIG) A field (HE-SIG-A) comprising a transmission opportunity (TXOP) duration field and a media access control (MAC) portion of the frame is not decoded, set one or more NAVs based on the TXOP duration field. The processing circuitry may be further configured to: decode a MAC portion of the frame, and if the MAC portion of the frame comprises a MAC duration field, set the one or more NAVs based on the MAC duration field.

Claim (Index 18):
A method performed by an apparatus of a high-efficiency (HE) station (STA), the apparatus configured to store a basic network allocation vector (NAV) and an intra-BSS NAV, the method comprising:\n decoding a physical layer (PHY) protocol data unit (PPDU); updating the basic NAV with a transmission opportunity (TXOP) duration indicated in an HE signal (SIG) A (HE-SIG-A) field of the PPDU if:\n the TXOP duration is a valid TXOP duration, \n the PPDU is an inter-basic service set (BSS) PPDU or cannot be identified as either an intra-BSS PPDU or the inter-BSS PPDU, and \n the TXOP duration is greater than a current value indicated by the basic NAV; \n updating the intra-BSS NAV with a duration indicated by a duration field of a physical service data unit (PSDU) of the PPDU if:\n the duration field of the PSDU comprises duration information, \n the PPDU is identified as the intra-BSS PPDU, \n a receiver address (RA) of the PPDU is not a media access control (MAC) address of the HE STA, and \n the duration indicated by the duration field of the PSDU is greater than a current value indicated by the intra-BSS NAV; and \n determining whether to transmit another frame based on the current value indicated by the intra-BSS NAV or the current value of the basic NAV.
