A method for transmitting a signal, comprising: sending, by a network device, a first synchronization signal of a first cell through a first beam, the first synchronization signal carrying identity information of the first beam; sending, by the network device through the first beam, a first broadcast message scrambled with the identity information of the first beam, the first broadcast message carrying identity information of at least one second beam in the first cell, and at least one of a location of a time domain resource or a location of a frequency domain resource occupied by a second synchronization signal sent through at least one second beam in the first cell, wherein a time domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a time domain resource for the first broadcast message sent through the first beam in the first cell; or a frequency domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a frequency domain resource for the first broadcast message sent through the first beam in the first cell; or a time domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a time domain resource for the first broadcast message sent through the first beam in the first cell and a frequency domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a frequency domain resource for the first broadcast message sent through the first beam in the first cell. sending, by a network device, a first synchronization signal of a first cell through a first beam, the first synchronization signal carrying identity information of the first beam; sending, by the network device through the first beam, a first broadcast message scrambled with the identity information of the first beam, the first broadcast message carrying identity information of at least one second beam in the first cell, and at least one of a location of a time domain resource or a location of a frequency domain resource occupied by a second synchronization signal sent through at least one second beam in the first cell, wherein a time domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a time domain resource for the first broadcast message sent through the first beam in the first cell; or a frequency domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a frequency domain resource for the first broadcast message sent through the first beam in the first cell; or a time domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a time domain resource for the first broadcast message sent through the first beam in the first cell and a frequency domain resource for the first synchronization signal sent through the first beam in the first cell does not overlap with a frequency domain resource for the first broadcast message sent through the first beam in the first cell.
