    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 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 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.
