User terminal and radio communication method

Abstract

A terminal is disclosed that includes a receiving section that receives a synchronization signal (SS) block, which includes a synchronization signal and a broadcast channel; and a control section that specifies identification information of the SS block, based on Demodulation Reference Signal (DMRS) that are multiplexed over a plurality of symbols for Physical Broadcast Channel (PBCH) in the SS block. In other aspects, a radio communication method is also disclosed.

1 . A user terminal comprising:
 a receiving section that receives a synchronization signal (SS) block, which includes a synchronization signal and a broadcast channel; and   a control section that specifies identification information of the SS block, based on Demodulation Reference Signal (DMRS) that are multiplexed over a plurality of symbols for Physical Broadcast Channel (PBCH) in the SS block.   
     
     
         2 . The user terminal according to  claim 1 , wherein the reference signal sequences in part of the plurality of symbols are generated based on at least part of the identification information of the SS block. 
     
     
         3 . The user terminal according to  claim 1 , wherein the reference signal sequences in each of the plurality of symbols are generated based on identification information of a cell in which the SS block is transmitted. 
     
     
         4 . The user terminal according to  claim 1 , wherein the mapping pattern in part of the plurality of symbols is cyclic-shifted based on at least part of the identification information of the SS block. 
     
     
         5 . The user terminal according to  claim 1 , wherein the frequency position in part of the plurality of symbols is shifted based on at least part of the identification information of the SS block. 
     
     
         6 . A radio communication method comprising, in a user terminal, the steps of:
 receiving a synchronization signal (SS) block, which includes a synchronization signal and a broadcast channel; and   specifying identification information of the SS block, based on Demodulation Reference Signal (DMRS) that are multiplexed over a plurality of symbols for Physical Broadcast Channel (PBCH) in the SS block.   
     
     
         7 . The user terminal according to  claim 2 , wherein the reference signal sequences in each of the plurality of symbols are generated based on identification information of a cell in which the SS block is transmitted. 
     
     
         8 . The user terminal according to  claim 2 , wherein the mapping pattern in part of the plurality of symbols is cyclic-shifted based on at least part of the identification information of the SS block. 
     
     
         9 . The user terminal according to  claim 3 , wherein the mapping pattern in part of the plurality of symbols is cyclic-shifted based on at least part of the identification information of the SS block. 
     
     
         10 . The user terminal according to  claim 2 , wherein the frequency position in part of the plurality of symbols is shifted based on at least part of the identification information of the SS block. 
     
     
         11 . The user terminal according to  claim 3 , wherein the frequency position in part of the plurality of symbols is shifted based on at least part of the identification information of the SS block. 
     
     
         12 . The user terminal according to  claim 4 , wherein the frequency position in part of the plurality of symbols is shifted based on at least part of the identification information of the SS block.
