Abstract: In a method of sending a frame using a cyclic shift diversity (CSD) sequence, a wireless device generates a frame comprising a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated legacy signal (RL-SIG) field, an extremely high throughput signal A (EHT-SIG A) field, and an extremely high throughput signal B (EHT-SIG B) field. The wire device sends the frame through a set of transmit antennas by performing cyclic shift over the fields according to a CSD sequence. The number of transmit antennas is greater than 8. The number of cyclic shift diversities in the CSD sequence is equal to a number of the transmit antennas, and each cyclic shift diversity has a value that is a multiple of 12.5.

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 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.
