Terminal and radio communication method

Abstract

A terminal is disclosed that includes a reception section that receives a first synchronization signal and a second synchronization signal mapped on predetermined resources and a control section that controls synchronization processing based on the first synchronization signal and the second synchronization signal, where a same transmission bandwidth and subcarrier spacing are applied to the first synchronization signal and the second synchronization signal. In other aspects, a radio communication method is also disclosed.

1 . A terminal comprising:
 a reception section that receives a first synchronization signal and a second synchronization signal mapped on predetermined resources; and   a control section that controls synchronization processing based on the first synchronization signal and the second synchronization signal,   wherein a same transmission bandwidth and subcarrier spacing are applied to the first synchronization signal and the second synchronization signal.   
     
     
         2 . The terminal according to  claim 1 , wherein spacings of the first synchronization signal and the second synchronization signal at which the first synchronization signal and the second synchronization signal are mapped on subcarriers are different. 
     
     
         3 . The terminal according to  claim 1 , wherein the first synchronization signal has a shorter sequence length and the wider spacing at which the first synchronization signal is mapped on the subcarrier than those of the second synchronization signal. 
     
     
         4 . The terminal according to  claim 3 , wherein the second synchronization signal is mapped on contiguous subcarriers or a subcarrier arranged per predetermined spacing. 
     
     
         5 . The terminal according to  claim 1 , wherein an identical numerology to that of the first synchronization signal and/or the second synchronization signal, or a scaled numerology is used to detect at least one of a broadcast channel and a reference signal. 
     
     
         6 . The terminal according to  claim 1 , wherein the first synchronization signal is formed by one pattern, and the second synchronization signal is formed based on a number of patterns corresponding to a number of cell IDs. 
     
     
         7 . A radio communication method of a terminal that communicates with a radio base station, the radio communication method comprising:
 a step of receiving a first synchronization signal and a second synchronization signal mapped on predetermined resources; and   a step of controlling synchronization processing based on the first synchronization signal and the second synchronization signal,   wherein the first synchronization signal and the second synchronization signal are applied a same transmission bandwidth and subcarrier spacing.
