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 to improve the area throughput of dense wireless local area networks (WLAN) by channel access control is proposed. The method allows an access point to obtain information of a plurality of stations within the wireless network. The access point classifies the plurality of stations into at least one group of stations and assigns a group identification (ID) according to the obtained information. The group ID and channel access control parameters are sent to the stations that are classified into the certain group. The stations in each of the group use the received channel access control parameters to communicate with the access point.

摘要： A communication system is provided. A first communications device transmits at least one first message including predetermined bit sequences. A second communications device determines one or more antenna weighting vectors (AWVs) and one or more bitloading vectors (BLVs) by using the first message in accordance with a predetermined rule and transmits a second message including information pertinent to the AWVs and the BLVs to the first communications device. The first communications device further communicates with the second communications device about an AWV selected from the AWVs and the first and second communications devices apply the selected AWV to the corresponding antennas before exchanging data. The data includes a header carrying information pertinent to a BLV selected from the BLVs used to encode the data and a payload is transmitted to the second communications device. The second communications device decodes the data in accordance with the selected BLV.

摘要： A method of combined direction finding (DF) and fine timing measurement (FTM) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device (AP) can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas, which allows a receiving device (STA) to resolve multiple DF sounding signals transmitted from the multiple antennas and thereby estimating angle of departure (AoD). On the other hand, the AP can estimate angle of arrival (AoA) from radio signals transmitted from the STA. When the radial resolution error of AoD or AoA positioning increases, DF positioning and fine-timing measurement (FTM) ranging can be jointly applied to reduce the radial resolution error and extends the AoD/AoA service area with positing accuracy.

摘要： A method is provided for sharing a communications channel in a wireless communications system. A network coordinating device of the wireless network obtains a first path quality information of each of a first set of one or more communications paths between a first pair of communications devices. The coordinating device also obtains a second path quality information of each of a second set of communications paths between a second pair of communications devices. The coordinating device then determines one or more co-existing communications paths based on the first and the second path quality information in accordance with a predetermined rule. Finally, the coordinating device sends channel resource allocation information to the first pair and the second pair of communications devices to use corresponding co-existing communications paths such that the first pair and the second pair of communications devices communicate over the communications channel during a period of time concurrently.
