A wireless communication method and device

Abstract

An embodiment of the invention discloses a wireless communication method which comprises the following steps: a first type device receives signals for communication between at least two second type devices and obtaining received signal strength indicator value of the signals, wherein the first type device supports a transmission power control mechanism and a receiver sensitivity control mechanism, and the second type device supports or does not support the transmission power control mechanism and the receiver sensitivity control mechanism; and the first type device adjusts signal transmission power required for communication with a target device according to the received signal strength indicator value. Correspondingly, the invention also discloses a wireless communication device. Through the wireless communication method and device, when new equipment and old equipment coexist, access delay of the old equipment is prevented, and user experience of the old equipment is enhanced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless communication method and equipment. Background technique [0002] With the advancement of information communication technology, various wireless communication technologies have recently been developed. Among these wireless communication technologies, wireless local area network (WLAN) is a wireless communication technology that can be used in homes or businesses or in areas that provide specific services by using portable terminals (such as smart mobile terminals, tablet computers, portable multimedia players, etc.) way of surfing the web. In the existing Wi-Fi technology, due to co-channel interference, in OBSS (overlapping basic service set, overlapping basic service set), when a station STA communicates with an access point AP, other devices do not able to communicate, which makes spectrum utilization less efficient. [0003] Currently, the 802.11 pr...

Problems solved by technology

However, for old devices (i.e., devices that do not support TPC and DSC), after the communication is completed, if the new device (i.e., devices that support TPC and DSC) is still communicating, there is an access delay for the old device, such as figure 1 As shown, STA1 and STA2 are old devices, STA3 and STA4 are new devices, TXOP1 is the communication duration between STA1 and STA2, and TXOP2 is the communication duration between STA3 and STA4. Since the communication between STA1 and STA2 ends, STA3 and STA4 are communicating, so , if STA1 and STA2 still need to communicate at the end of the communication, they need to wait until the end of the communication between STA3 and STA4 to communicate, that is, there is a delay of ΔΤ
