摘要： 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.

摘要： The present invention is a method and apparatus for dynamically adjusting deferred transmission level and a transmission power level in a wireless communication system implementing carrier sense multiple access/collision avoidance (CSMA/CA) mechanism. A plurality of transmission power levels and associated metrics are defined for an access point (AP) and a wireless transmit/receive unit (WTRU). If a packet originated from a neighboring basic service set (BSS) is received, the metric is updated for each of the transmission power levels. The metric is increased if it is determined that transmission at a particular transmission power level associated to the metric would cause a partial defer to a sender and a receiver of the packet. The AP and the WTRU selects a transmission power level having a smallest metric. The AP and WTRU may also adjust the deferred transmission level in accordance with measurement results.

摘要： A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted consecutively from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.

摘要： A method and apparatus for protecting high throughput (HT) stations (STAs) are disclosed. In one embodiment, a physical layer (PHY) legacy preamble transmitted by one STA is decoded by another STA that does not use a legacy preamble. In another embodiment, one STA is identified by another STA by using bits in the preamble of a packet to indicate which PHY type will be used in the remaining portion of the packet. In yet another embodiment, one STA sends ready-to-send (RTS)/clear-to-send (CTS) or CTS-to-self messages for reserving a medium in the presence of another STA of a different type than the one STA. In yet another embodiment, an access point (AP) transmits a beacon or an association message including a capability information element (IE) that indicates operation or support for a legacy preamble, HT STA preambles and a medium access control (MAC) packet transmission with HT protection mechanisms.

摘要： A access point (AP) during wireless communication with at least one wireless transmit/receive unit (WTRU), transmits a beacon signal periodically among a plurality of sectors, each sector having its own sector identity, the beacon signal being periodically received at least once in a beacon period and the beacon period comprising a plurality of beacon service periods for all sectors. The AP determines a scheduling value to indicate a number of inactive beacon periods for a first sector to at least one WTRU located in the first sector. The scheduling value is transmitted with the sector identity for the first sector, such that a variable beacon period is established for the first sector, enabling the at least one WTRU located in the first sector to enter a sleep mode for an adjustable period of time.

摘要： A method and apparatus for selecting one of a plurality of multi-band access points (APs) to associate with a multi-band wireless transmit/receive unit (WTRU) are disclosed. The multi-band APs broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU selects a particular multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. If the multi-band WTRU receives frequency band information from the selected multi-band AP which indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band is unacceptable, the multi-band WTRU determines whether to disassociate with the selected multi-band AP or to continue to associate with the selected multi-band AP via a different frequency band.

摘要： A method for transmitting a packet from a transmitter to a receiver in a wireless communication system begins by building a packet by a transport format combination (TFC) selection process, and the packet is transmitted from the transmitter to the receiver. If the transmitter receives an indication that the packet was not successfully received at the receiver, the packet is retransmitted via a hybrid automatic repeat request (HARQ) procedure. If the HARQ procedure did not successfully transmit the packet, then the packet is retransmitted via a retransmission management (RM) procedure. If the RM procedure did not successfully transmit the packet, then the packet is discarded by the transmitter.
