Problems solved by technology

When STA1 limits its own transmission power in order not to interfere with the signal transmission of STA2, because the distance between STA1 and AP2 is too short, the signal power of STA1’s PPDU still has the risk of being higher than the signal detection threshold of AP2 when it is transmitted to AP2. Make it impossible for AP2 to ignore the PPDU from STA1, resulting in data transmission conflict

Abstract

The invention discloses a sending power control method and device of communication equipment, equipment and a storage medium, and the method comprises the steps: obtaining a spatial multiplexing parameter of a basic service set where the equipment is located when a negligible first physical layer protocol data unit which is sent to an access point by a station of an overlapped basic service set is received; wherein the spatial multiplexing parameters comprise a minimum signal detection threshold value, a sending power reference value and a signal detection level value; calculating a first sending power limit value according to the spatial multiplexing parameter; obtaining a path loss value from the access point to the device; obtaining a minimum signal detection threshold value of the access point; calculating a second sending power limit value according to the path loss value and a minimum signal detection threshold value of the access point; and adjusting the maximum sending power of the equipment according to the first sending power limit value and the second sending power limit value. According to the invention, the data transmission conflict between the overlapped basic service sets can be effectively avoided in the spatial multiplexing technology.

Description

technical field [0001] The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, a terminal device, and a computer-readable storage medium for controlling transmission power of a communication device. Background technique [0002] In the 802.11ax protocol, Spatial Reuse (SR) is introduced. The Spatial Reuse technology mainly has two operation modes: Overlapping Basic Service Set Packet Detect based Spatial Reuse, referred to as OBSS PD-based SR), and spatial multiplexing based on spatial multiplexing parameters (Parameterized Spatial Reuse based Spatial Reuse, referred to as PSR-based SR). In the OBSS PD-based spatial multiplexing operation, the station of the Basic Service Set (BSS) receives the Physical Layer Protocol Data Unit (Physical Layer Protocol Data) of the Overlapping Basic Service Set (OBSS) Unit, referred to as PPDU), ignore the transmission of the PPDU and limit its own transmission power t...
