Signal transmission method and communications device
Embodiments of this disclosure provide a signal transmission method and a communications device. The method includes: determining a transmission priority in a case that transmission of a first signal conflicts with transmission of a second signal; and preferentially transmitting or receiving the first signal based on the transmission priority, or preferentially transmitting or receiving the second signal based on the transmission priority; where the first signal includes a SLSS or a signal carried by a PSBCH.
1. A signal transmission method, comprising:
determining a transmitting or receiving priority of a first signal is lower than a transmitting or receiving priority of the second signal in a case that transmission of a first signal conflicts with transmission of a second signal; wherein the first signal comprises a sidelink synchronization signal (SLSS) or a signal carried by a physical sidelink broadcast channel (PSBCH), the second signal comprises physical random access channel (PRACH) data over a Uu interface; and
preferentially transmitting or receiving the second signal.
2. The method according to claim 1 , wherein
the first signal and the second signal are of different radio access technologies or a same radio access technology.
3. The method according to claim 1 , wherein the preferentially transmitting or receiving the second signal comprises:
transmitting the second signal, and stopping transmitting the first signal; or transmitting the second signal, and transmitting the first signal at a reduced power.
4. A communications device, comprising a memory, a processor, and a program stored in the memory and capable of running on the processor, wherein the computer program, when executed by the processor, causes the communications device to perform-:
determining a transmitting or receiving priority of a first signal is lower than a transmitting or receiving priority of the second signal in a case that transmission of a first signal conflicts with transmission of a second signal; wherein the first signal comprises a sidelink synchronization signal (SLSS) or a signal carried by a physical sidelink broadcast channel (PSBCH), the second signal comprises physical random access channel (PRACH) data over a Uu interface; and
preferentially transmitting or receiving the second signal.
5. The communications device according to claim 4 , wherein
the first signal and the second signal are of different radio access technologies or a same radio access technology.
6. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implements:
determining a transmitting or receiving priority of a first signal is lower than a transmitting or receiving priority of the second signal in a case that transmission of a first signal conflicts with transmission of a second signal; wherein the first signal comprises a sidelink synchronization signal (SLSS) or a signal carried by a physical sidelink broadcast channel (PSBCH), the second signal comprises physical random access channel (PRACH) data over a Uu interface; and
preferentially transmitting or receiving the second signal.
