Abstract

The invention discloses a synchronizing method and device. Information of main synchronizing signals and information of auxiliary synchronizing signals are determined, wherein each information comprises the number and the symbol lengths; and the main synchronizing signals are synchronized according to the information of the main synchronizing signals, and the auxiliary synchronizing signals are synchronized according to the information of the auxiliary synchronizing signals. The synchronizing method that one system supports multiple subcarrier spacings is provided, compared with the subcarrierspacing of M*15kHz, the system provides the PSS and SSS with the corresponding subcarrier spacings, the expense of the synchronizing signals can be reduced, and the cell synchronizing purpose is achieved by sharing a certain synchronizing signal.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a synchronization method and device. Background technique [0002] The 5G research topic Study on New Radio Access Technology was established in the 3GPP RAN 70 plenary session, officially starting the research on 5G wireless air interface technology (referred to as NR). The sub-carrier spacing is 15kHz or M*15kHz (wherein M=2^n, n is an integer) and passed the conclusion in RAN1 84bis. That is, multiple subcarrier spacings are supported in NR, which means that multiple different symbol lengths are supported, unlike LTE which only supports a single 15kHz subcarrier spacing. [0003] When multiple subcarrier intervals exist in NR (New Radio), different symbol lengths are generated. When different UEs need to use resources with different subcarrier spacings, NR must support the synchronization of resources with different subcarrier spacings, w...
