Abstract: An electron device and a wireless communication method in a wireless communication system. The electron device includes one or more processing circuits configured to execute: determining positioning measurement assistant data for a user device, the assistant data including configuration information of an enhanced Discovery Reference Signal (eDRS) sent from at least one sleeping small cell base station; executing positioning measurement on the eDRS sent from at least one sleeping small cell base station on the basis of the assistant data; and generating positioning information on the basis of the result of positioning measurement on the eDRS sent from at least one sleeping small cell base station, so as to position the user device, the eDRS having greater transmitting power than a Discovery Reference Signal DRS.
