Abstract

The invention relates to electronic equipment, user equipment and a wireless communication method in a wireless communications system. The electronic equipment comprises one or more processing circuits which are configured to acquire NACK information indicating failure of information transmission between a sender and a receiver in a wireless communications system and failure cause information indicating the cause of information transmission failure, wherein the cause of information transmission failure may be a link quality cause or a non-link-quality cause; and when determining that the cause of information transmission failure is a non-link-quality cause, generating spectrum sensing parameter information to adjust the spectrum sensing parameters of the sender so as to improve the success probability of information transmission between the sender and the receiver. By using the electronic equipment, the user equipment and the wireless communication method of the invention, the cause of information transmission failure can be acquired, the spectrum sensing parameters are adjusted only when the cause of information transmission failure is a non-link-quality cause, unnecessary adjustment is avoided, and the performance of the system is improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to an electronic device in a wireless communication system, a user equipment and a method for performing wireless communication in the wireless communication system. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] With the development and evolution of wireless networks, more and more services are carried by them, so additional spectrum resources are required to support massive data transmission. On the basis of using the existing LTE (Long Term Evolution, long-term evolution) network, cellular wireless network operators have begun to explore how to use unlicensed spectrum resources such as 5GHz ISM (Industrial Scientific Medical, industry, science and medical) frequency band. On the other hand, the WiFi wireless industry is also deploying more WiFi s...
