Abstract

A cell search and synchronization method in a 5G wireless communication system in which a cell, with which a terminal wishes to synchronize, has a frequency span in the frequency domain. The method comprising setting (S100) a numerology for the system in dependence on the frequency span, which determines a channel raster used in the cell; defining (S102), using the channel raster, a plurality of possible resources distributed over the frequency span for transmitting PSS/SSS/PBCH; determining (S104) how many instances of PSS, SSS and PBCH are required in the current time period; transmitting (S106) the number of instances of PSS, SSS and PBCH thus determined; and a terminal detecting one or more instance of PSS/SSS/PBCH in order to connect with the cell. Multiple transmissions of PSS/SSS/PBCH allow a terminal to detect these signals more easily, and facilitate use of PSS or SSS as reference signs for RRM purposes. Different numbers of PSS/SSS/PBCH may be transmitted with respective mappings between them, and the numbers of transmissions may vary over time.
