Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and system for coexistence of multiple wireless communication devices. Background technique [0002] When multiple wireless communication devices work simultaneously in the same electronic device, coexistence interference will be formed in the electronic device. Most of the related technologies implement multi-network coexistence through simple time division multiplexing (TDM) or frame synchronization, or reduce system interference only by reducing power. [0003] Time-division multiplexing TDM coexistence is to divide time into different time segments. In each time segment, only one wireless communication device works, and other wireless communication devices are in a static state. However, this is at the cost of sacrificing system utilization, which will lead to System capacity is reduced. [0004] Frame synchronous coexistence is to align the ...

[0003] Time-division multiplexing TDM coexistence is to divide time into different time segments. In each time segment, only one wireless communication device works, and other wireless communication devices are in a static state. However, this is at the cost of sacrificing system utilization, which will lead to System capacity reduction

[0004] Frame synchronous coexistence is to align the sending and receiving times of each wireless communication device, and each wireless communication device sends or receives at the same time, but this method cannot solve the problem of co-channel interference, such as Wi-Fi and BT receiving at the same frequency. Coexistence interference is generated. In addition, this method cannot solve the problem that LTE SINR drops when LTE and Wi-Fi are simultaneously transmitted.
