The STA MLD establishes a connection with the AP according to the link information in the connection response message.
Generally, all paths that are traversed after various types of signals are transmitted from a transmitting end before reaching a receiving end are collectively referred to as a channel. If radio signals are transmitted, the path traveled by the electromagnetic waves is called a radio channel. The wireless channel is the most complex one compared to other communication channels. The radio propagation environment is an essential factor affecting the wireless communication system. The wireless propagation path between the transmitter and the receiver is very complicated from the propagation through a simple line of sight to the propagation of reflection, diffraction and scattering caused by the encounter with various complex features (such as buildings, mountains, forests, etc.). Further, the direction and speed of movement of the mobile station relative to the transmitting station, and even the moving object in the vicinity of both the transmitting and receiving sides, have a large influence on the received signal. This therefore makes the radio channel extremely random. The relationship between the transmitted signal power, the received signal power, and the channel model can be expressed as:
R = CHF X T + N（1）
in formula (1), R is the received signal power; CHF is a channel model; t is the transmission signal power; and N is noise power.
The channel model for judging which channel model the transmission between the transmitting terminal and the receiving terminal accords with can be calculated through the formula (1), the transmitting signal power of the AP of the current connected link is used as input, the receiving signal power R is obtained through calculation by using a theoretical white noise constant N1 or N2 obtained through calculation according to a dynamic noise calculation formula, and the channel model which is closest to the actual receiving signal power measured by the current STA MLD is selected as the channel model for calculating the receiving signal power of the target link. Illustratively, the dynamic noise calculation formula is as follows:
wherein, the noise function p (f) may be:
it can also be:
wherein f is the frequency value, fmax is the highest frequency value of the operation frequency band, fmin is the lowest frequency value of the operation frequency band, fc is the central frequency value of the operation frequency band,
is a preset noise constant.
