1. A signal transmission method, comprising:
generating a second narrowband positioning reference signal sequence at least according to a system frame number (SFN); and
determining a second narrowband positioning reference signal according to the second narrowband positioning reference signal sequence;
wherein generating the second narrowband positioning reference signal sequence at least according to the SFN comprises:
ak,l(p)=rl,ns((m′+2·(SFN modM))mod220),
where rl,ns ( ) denotes a first narrowband positioning reference signal sequence, m′ denotes a position of a modulation symbol in the sequence rl,ns ( ) and M denotes a value configured by the base station or a predefined value.
