Abstract: Embodiments provide a method for accessing an access point by a station device, a device, and a system. A station device selects a master access point from multiple access points according to channel quality and accesses the master access point, and sends information about remaining access points to the master access point, so that the master access point selects a slave access point according to the information about the remaining access points. In this way, the master access point coordinates with the slave access point to perform data transmission with the station device.

Abstract: A method and system for providing utilization information for a basic service set (BSS) in a wireless local area network system, performed by an access point, including generating and transmitting a BSS load element including a capable STA count field, a plurality of frequency and/or spatial stream underutilization fields, and a plurality of delta observable secondary channel utilization fields. The capable STA count field indicates a total number of STAs currently associated with the BSS. Each of the frequency and/or spatial stream underutilization fields indicates underutilized frequency and/or spatial stream domain resources on Orthogonal Frequency Division Multiple Access resource units for each channel, and each of the frequency and/or spatial stream underutilization fields is calculated based on RU size. Each of the delta observable secondary channel utilization fields indicates a utilization for a subband within a secondary channel calculated based on observable utilization on the corresponding secondary channel.

Abstract: Embodiments of the present invention provide a data transmission method and apparatus. The data transmission method includes: receiving, by a third site, a first transmit frame transmitted by a first site to a second site, and acquiring a transmission end moment of the first transmit frame; transmitting, by the third site, a second transmit frame to a fourth site, and instructing the fourth site to delay returning a response frame; and receiving, by the third site after at least one preset time length after transmission of the second transmit frame ends, the response frame transmitted by the fourth site; where a transmission end moment of the second transmit frame is not later than the transmission end moment of the first transmit frame. The embodiments of the present invention implement that the third site can also transmit data when the first site transmits data, which improves system transmission efficiency.

Abstract: The present disclosure provides a wireless network-based positioning method and positioning apparatus. The positioning method includes: obtaining time information used for determining a current location of a to-be-positioned node, where the time information records times of arrival of a first sounding signal; determining time differences of arrival of the first sounding signal at the at least three anchor nodes according to recorded historical information and the time information; and determining the current location of the to-be-positioned node according to locations of the at least three anchor nodes and the time differences of arrival of the first sounding signal at the at least three anchor nodes. By means of the present disclosure, time differences of arrival of a sounding signal at different anchor nodes can be accurately determined, thereby determining an accurate location of a to-be-positioned node and avoiding synchronization between the anchor nodes.
