Electronic device and user equipment in wireless communication system and wireless communication method

An electronic device in a wireless communication system, comprising:

• one or more processing circuits configured to:
• acquire a NACK message indicating failed information transmission between a transmitting end and a receiving end in the wireless communication system and failure cause information indicating a cause of the failed information transmission, to inform a spectrum management server in the wireless communication system, wherein the cause of the failed information transmission comprises a link quality cause and a non-link quality cause;
• and
• acquire spectrum sensing parameter information from the spectrum management server to adjust a spectrum sensing parameter of the transmitting end, so as to increase a probability of successful information transmission between the transmitting end and the receiving end.

A user equipment in a wireless communication system, wherein the user equipment operates as a receiving end and comprises:

• a transceiver;
• and
• one or more processing circuits configured to:
• generate a NACK message indicating failed information transmission between a base station serving as a transmitting end and the user equipment in the wireless communication system and failure cause information indicating a cause of the failed information transmission, wherein the cause of the failed information transmission comprises a link quality cause and a non-link quality cause;
• and
• control the transceiver to transmit the NACK message and the failure cause information to the base station, to inform a spectrum management server in the wireless communication system.
