Abstract
Embodiments of this application provide a communication method and system, and an apparatus, and relate to the field of communication technologies An example method includes obtaining a first carrier spacing, where the first carrier spacing is N times a second carrier spacing corresponding to a first low-frequency channel, and N>1. The method further includes modulating a to-be-sent high-frequency physical layer signal based on the first carrier spacing to generate a first PPDU. The method further includes sending the first PPDU to a receive device through a first high-frequency channel.
Claims20
A communication method, applied to a transmit device, wherein the method comprises:
- obtaining a first carrier spacing, wherein the first carrier spacing is N times a second carrier spacing corresponding to a first low-frequency channel, and N>1;
- modulating a to-be-sent high-frequency physical layer signal based on the first carrier spacing to generate a first physical layer protocol data unit (PPDU);
- and
- sending the first PPDU to a receive device through a first high-frequency channel.
A communication method, applied to a receive device, wherein the method comprises:
- obtaining a first carrier spacing, wherein the first carrier spacing is N times a second carrier spacing corresponding to a first low-frequency channel, and N>1;
- receiving a first physical layer protocol data unit (PPDU) from a transmit device through a first high-frequency channel, wherein the first PPDU is a high-frequency physical layer signal;
- and
- demodulating the first PPDU based on the first carrier spacing.
A device, comprising at least one processor and at least one memory coupled to the at least one processor, wherein the at least one memory stores programming instructions for execution by the at least one processor to cause the device to perform operations comprising:
- obtaining a first carrier spacing, wherein the first carrier spacing is N times a second carrier spacing corresponding to a first low-frequency channel, and N>1;
- modulating a to-be-sent high-frequency physical layer signal based on the first carrier spacing to generate a first physical layer protocol data unit (PPDU);
- and
- sending the first PPDU to a receive device through a first high-frequency channel.
