Electron device and wireless communication method in wireless communication system

An electronic device at a user equipment side, comprising:

• one or more processing circuits configured to perform operations of:
• determining positioning measurement auxiliary data for the user equipment, the positioning measurement auxiliary data including configuration information of an enhanced discovery reference signal (eDRS) transmitted by at least one sleeping small cell base station;
• performing positioning measurement on the eDRS transmitted by the at least one sleeping small cell base station and reference signals transmitted by two other cell base stations based on the positioning measurement auxiliary data and calculating a reference signal time difference (RSTD);
• and
• generating positioning information based on a result of the positioning measurement performed on the eDRS transmitted by the at least one sleeping small cell base station to perform positioning on the user equipment and the calculated RSTD,
• wherein the eDRS has a greater transmission power than a discovery reference signal (DRS);
• and
• wherein the eDRS is different than a positioning reference signal (PRS).
