Abstract

The invention relates to an electronic device and wireless communication method in a wireless communication system. The electronic device comprises one or more processing circuits which are configured for performing the operations of determining positioning measurement auxiliary data for user equipment, wherein the auxiliary data comprises configuration information of an enhanced discovery reference signal eDRS sent by at least one sleep small cell base station; carrying out positioning measurement on the eDRS sent by the at least one small cell base station based on the auxiliary data; and generating positioning information based on the result obtained by carrying out the positioning measurement on the eDRS sent by the at least one small cell base station, thereby positioning the user equipment, wherein the eDRS has higher transmitting power than that of a discovery reference signal DRS. According to the electronic device and the wireless communication method disclosed by the invention, the existing DRS signal can be utilized fully, the DRS signal is suitably enhanced, the positioning precision is improved, and a positioning process is accelerated.

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 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] SCN (Small Cell Network, small cell network) is considered to be an effective means to cope with the rapid growth of data traffic. In the standardization discussion of wireless communication, a new reference signal - DRS (Discovery Reference Signal, Discovery Reference Signal), is used to support the small cell on / off (small cell on / off) mechanism. In the off state of the small cell, the base station of the small cell only sends the DRS. [0004] Indoor positioning is one of the key tasks of wireless communication technology standardization. The existing O...
