         2 . The method of  claim 1 , wherein the network device sends the first message together with the second message. 
     
     
         3 . The method of  claim 1 , wherein the first message is carried in a second information field besides the first information field in the PBCH.

 sending, by the network device, a message to the user equipment, wherein the message is configured for indicating the first frequency domain range.   
     
     
         6 . A detection method, comprising:
 receiving, by a user equipment, a first synchronization signal block (SSB) from a network device, the first SSB comprising a physical broadcast channel (PBCH), the first SSB being not associated with remaining minimum system information (RMSI), wherein the PBCH comprises an indication for indicating a first frequency domain location of a second SSB in a first frequency domain range, and wherein the second SSB is associated with the RMSI; and   detecting, by the user equipment, the second SSB based on the indication;   wherein the indication comprises:   a first message for indicating the first frequency domain range; and   a second message for indicating the first frequency domain location of the second SSB;   wherein the second message is carried in a first information field in the PBCH, and wherein the first information field comprises an information field for a control resource set (CORESET) of the RMSI.   
     
     
         7 . The method of  claim 6 , wherein the first message and the second message are sent together by the network device. 
     
     
         8 . The method of  claim 6 , wherein the first message is carried in a second information field besides the first information field in the PBCH. 
     
     
         9 . The method of  claim 8 , wherein the second information field comprises at least one of the following: coded bits in a physical resource block (PRB) grid offset information field, subcarrier spacing (SCS) information of the RMSI, cell access prohibition indication information, and intra-frequency reselection information.
