Abstract: The present disclosure provides a method and an apparatus for transmission of a synchronization signal. The method includes: transmitting, by a base station, the synchronization signal repeatedly and periodically to a terminal. In one repetition period, the synchronization signal is transmitted over time corresponding to a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols in one or more subframes. The synchronization signal is a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS). Alternatively, the method includes: receiving, by a terminal, the synchronization signal transmitted from a base station repeatedly and periodically. In this way, the problem associated with inappropriate design of the synchronization signals in the NB-LTE system can be solved and proper transmission of the synchronization signals in the narrow band system can be achieved.

Abstract: The present invention provides a method and an apparatus for determining a position of a terminal, and a storage medium. The method comprises: sending first DCI or a paging message to a terminal, wherein the first DCI or the paging message is used for triggering the terminal to send a signal and the transmission of the first DCI is started at a paging moment of the terminal; and determining a position of the terminal according to the signal sent by the terminal. The technical solution solves the problem in the related art that a position of a terminal is determined only depending on an uplink signal sent by the terminal device in a connected state, and can easily determine the position of the terminal, thereby avoiding unnecessary power consumption of the terminal and helping saving power of a terminal device.
