Abstract
Network Allocation Vector (NAV) and “beam access control” (BAC) techniques are provided to address data collision problems in WLANs wherein APs provide wireless network access in a service area defined by multiple sectors via use of a switchable antenna system or the like. Preferably, every time the AP visits a sector and before the AP moves on to the next sector, the AP can set the NAV equal to the time it will take until its next visit. Alternatively, or in addition, a BAC bit is transmitted by an AP to control access to the AP by WTRUs disposed in a service sector in which the BAC is transmitted.
Claims21
A wireless transmit/receive unit (WTRU) comprising:
- a transceiver configured to receive at least one beam access control (BAC) signal transmitted by an access point (AP) via at least one directional beam in a sector in which the WTRU is located;
- and
- a controller configured to control the transmission of a plurality of signals by the transceiver in response to the at least one BAC signal received by the transceiver.
A wireless transmit/receive unit (WTRU) comprising:
- a transceiver configured to receive at least one Network Allocation Vector (NAV) signal transmitted by an access point (AP) via at least one directional beam in a sector in which the WTRU is located;
- and
- a controller configured to control the transmission of a plurality of signals by the transceiver in response to the at least one NAV signal received by the transceiver.
A wireless transmit/receive unit (WTRU) comprising:
- a transceiver configured to receive at least one beam access control (BAC) and a Network Allocation Vector (NAV) signal transmitted by an access point (AP) via at least one directional beam in a sector in which the WTRU is located;
- and
- a controller configured to control the transmission of a plurality of signals by the transceiver in response to the at least one BAC signal and the NAV signal received by the transceiver.
