摘要： A method of sub-channel feedback in OFDMA systems is provided. A wireless receiving device (STA) receives a radio signal from a transmitting device (AP) over a wide channel in an OFDMA system. The radio signal is transmitted over multiple sub-channels of the wide channel. The STA estimates channel quality information based on the received radio signal for each sub-channel. The STA then sends feedback information to the transmitting device. The feedback information comprises the estimated channel quality information for a selected subset of sub-channels from the wide channel based on a predefined rule. In one embodiment, the feedback information is embedded within an ACK/BA frame or is carried in a frame immediately subsequent to the ACK/BA frame.

摘要： A method of direction finding (DF) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas simultaneously, which allows a receiving device to resolve multiple DF sounding signals transmitted from the multiple antennas. As a result, angle of departure (AoD) of the transmitting device can be estimated by using the multiple resolved DF sounding signals from each antenna for DF positioning purpose.

摘要： A method for identifying source BSS in WLAN is proposed. A high efficiency (HE) access point (AP) sends a packet containing a basic service set (BSS) color to a HE station. The HE AP also sends a packet containing an assigned association identification (AID) to a very high throughput (VHT) station. The assigned AID comprises at least part of the BSS color information. The VHT station therefore sends a packet containing the at least part of the BSS color information such that any AP or station that receives the packet can determine the BSS the VHT station is in.

摘要： The present invention relates generally to wireless transceivers, and more particularly but not exclusively to non 802.11 detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting non 802.11 operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as AP, are provided. An AP is used to automatically detect the presence of non 802.11 on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of non 802.11 using one or more implementations.
