Abstract
Provided are a signal transmission method, apparatus, and device, and a storage medium. The method includes generating a second narrowband positioning reference signal sequence according to a system frame number (SFN); obtaining a second narrowband positioning reference signal according to the second narrowband positioning reference signal sequence; and transmitting a first narrowband positioning reference signal on a first radio frame set, and transmitting the second narrowband positioning reference signal on a second radio frame set.
Claims10
A signal transmission method, comprising:
- generating a second narrowband positioning reference signal sequence at least according to a system frame number (SFN);
- obtaining a second narrowband positioning reference signal according to the second narrowband positioning reference signal sequence;
- and
- transmitting a first narrowband positioning reference signal on a first radio frame set, and transmitting the second narrowband positioning reference signal on a second radio frame set;
- wherein generating the second narrowband positioning reference signal sequence at least according to the SFN comprises:
- ak,l(p)=rl,ns((m′+2·(SFN mod M))mod 220),
- where rl,ns( ) denotes the first narrowband positioning reference signal sequence, m′ denotes a position of a symbol in the sequence rl,ns( ), and M denotes a value configured by the base station or a predefined value.
A signal transmission device, comprising a memory and a processor, wherein the memory is configured to store a computer program about signal transmission and the processor executes the computer program to perform the following steps:
- generating a second narrowband positioning reference signal sequence at least according to a system frame number (SFN);
- obtaining a second narrowband positioning reference signal according to the second narrowband positioning reference signal sequence;
- and
- transmitting a first narrowband positioning reference signal on a first radio frame set, and transmitting the second narrowband positioning reference signal on a second radio frame set;
- wherein generating the second narrowband positioning reference signal sequence at least according to the SFN comprises:
- ak,l(p)=rl,ns((m′+2·(SFN mod M))mod 220),
- where rl,ns( ) denotes the first narrowband positioning reference signal sequence, m′ denotes a position of a symbol in the sequence rl,ns( ), and M denotes a value configured by the base station or a predefined value.
A non-transitory computer-readable storage medium, storing a computer program about signal transmission, wherein the computer program is configured to, when executed by at least one processor, cause the at least one processor to perform the following steps:
- generating a second narrowband positioning reference signal sequence at least according to a system frame number (SFN);
- obtaining a second narrowband positioning reference signal according to the second narrowband positioning reference signal sequence;
- and
- transmitting a first narrowband positioning reference signal on a first radio frame set, and transmitting the second narrowband positioning reference signal on a second radio frame set;
- wherein generating the second narrowband positioning reference signal sequence at least according to the SFN comprises:
- ak,l(p)=rl,ns((m′+2·(SFN mod M))mod 220),
- where rl,ns( ) denotes the first narrowband positioning reference signal sequence, m′ denotes a position of a symbol in the sequence rl,ns( ), and M denotes a value configured by the base station or a predefined value.
