Abstract
This application provides a signal transmission method and apparatus. The method includes: sending a first synchronization signal on a first time-frequency resource, where the first time-frequency resource includes a plurality of first frequency units in a first time unit, and sending a second synchronization signal on a second time-frequency resource, where the second time-frequency resource includes a plurality of second frequency units in the first time unit, and the plurality of first frequency units alternate with the plurality of second frequency units in frequency domain. Technical solutions in embodiments of this application can improve synchronization efficiency.
Claims20
A signal transmission method, comprising:
- receiving a first synchronization signal on a first time-frequency resource, wherein the first time-frequency resource comprises a plurality of first frequency units in a first time unit;
- and
- receiving a second synchronization signal on a second time-frequency resource, wherein the second time-frequency resource comprises a plurality of second frequency units in the first time unit, and the plurality of first frequency units alternate with the plurality of second frequency units in frequency domain.
A signal transmission apparatus, comprising a processor and a transceiver, wherein
- the transceiver is configured to receive a first synchronization signal on a first time-frequency resource, wherein the first time-frequency resource comprises a plurality of first frequency units in a first time unit, and receive a second synchronization signal on a second time-frequency resource, wherein the second time-frequency resource comprises a plurality of second frequency units in the first time unit, and the plurality of first frequency units alternate with the plurality of second frequency units in frequency domain;
- and
- the processor is configured to perform downlink communication link synchronization based on the first synchronization signal and the second synchronization signal.
A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores program code, and the program code, when executed by a processing system cause the processing system to perform operations comprising:
- receiving a first synchronization signal on a first time-frequency resource, wherein the first time-frequency resource comprises a plurality of first frequency units in a first time unit;
- and
- receiving a second synchronization signal on a second time-frequency resource, wherein the second time-frequency resource comprises a plurality of second frequency units in the first time unit, and the plurality of first frequency units alternate with the plurality of second frequency units in frequency domain.
