    Abstract: A method of receiving a downlink (DL) signal by a user equipment (UE) operating on a frequency band above 6 GHz in a wireless communication system is discussed. The method includes receiving system information including first information related to one or more synchronization signal (SS) and PBCH (SS/PBCH) block groups and second information related to one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups; and receiving the DL signal in resources other than resources used for the one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups indicated by the first and second information.

    Abstract: A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.

    Abstract: A disclosure of the present specification provides a rake receiver. The rake receiver may comprise: an oscillator; a radio frequency integrated circuit (RFIC) for processing analog signals, which are received after experiencing multipath propagation, according to a sampling clock generated by the oscillator and a carrier frequency clock; a rake processing unit for allocating fingers for each path to signals output from the RFIC, and then performing decoding, wherein the rake processing unit outputs information on a timing position through time tracking, a power metric sampled on-time, and the difference between a power metric at a half chip early-time and a power metric at a half chip late-time; and an auto frequency controller (AFC) for calculating a beta (β) value for adjusting the sampling clock of the oscillator according to the ratio of the difference between the power metric at the half chip early-time and the power metric at the half chip late-time to the power metric sampled on-time.
