Abstract
This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.
Claims18
A method, comprising:
- determining, by a network device, a target frequency resource, wherein a frequency domain position of the target frequency resource meets the following relation:
- p=offset+n*frequency_interval,
- wherein p is the frequency domain position of the target frequency resource, offset is a frequency domain position offset, n is an integer, and frequency_interval is a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels meets 2m times 180 kHz or 2m times 360 kHz, and wherein m is a nonnegative integer;
- and
- sending, by the network device based on the target frequency resource, a synchronization signal.
An apparatus, comprising:
- at least one memory including executable instructions;
- and
- at least one processor;
- wherein the executable instructions, when executed by the at least one processor, cause the apparatus to:
- determine a target frequency resource, wherein a frequency domain position of the target frequency resource meets the following relation:
- p=offset+n*frequency_interval,
- wherein p is the frequency domain position of the target frequency resource, offset is a frequency domain position offset, n is an integer, and frequency_interval is a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels meets 2m times 180 kHz or 2m times 360 kHz, and wherein m is a nonnegative integer;
- and
- send, based on the target frequency resource, a synchronization signal.
A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause a network device to carry out the following:
- determining a target frequency resource, wherein a frequency domain position of the target frequency resource meets the following relation:
- p=offset+n*frequency_interval,
- wherein p is the frequency domain position of the target frequency resource, offset is a frequency domain position offset, n is an integer, and frequency_interval is a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels meets 2m times 180 kHz or 2m times 360 kHz, and wherein m is a nonnegative integer;
- and
- sending, based on the target frequency resource, a synchronization signal.
