Electronic device, method and computer-readable medium

An electronic device, comprising a circuitry configured to:

• receive a radio communication signal for another device;
• determine, based on the radio communication signal, one or more features that can reflect a difference between an uplink transmission mode and a downlink transmission mode;
• and
• judge whether the radio communication signal is for the uplink transmission or the downlink transmission according to the one or more features.

A method used in a radio communication system, comprising:

• receiving by a circuitry a radio communication signal for another device;
• determining by the circuitry, based on the communication signal, one or more features that can reflect a difference between an uplink transmission mode and a downlink transmission mode;
• and
• judging by the circuitry whether the radio communication signal is for the uplink transmission or the downlink transmission according to the one or more features.

A non-transitory computer-readable medium encoded with computer-readable instructions thereon, the computer-readable instructions, when executed by a computer, cause the computer to perform a method comprising:

• receiving a radio communication signal for another device;
• determining, based on the communication signal, one or more features that can reflect a difference between an uplink transmission mode and a downlink transmission mode;
• and
• judging whether the radio communication signal is for the uplink transmission or the downlink transmission according to the one or more features.
