Abstract
Embodiments provide a signal sending method and a device, and relates to the communications field. The method includes determining, by a device, whether a CCA end moment is a first signal sending moment; and if the CCA end moment is the first signal sending moment, sending, by the device, a signal at the first signal sending moment. The present invention is used for signal sending.
Claims16
A method, performed by a device, the method comprising:
- grouping, by the device, 0, 1, . . . , N−1 into M groups, wherein each group of the M groups corresponds to a respective signal sending moment of a plurality of signal sending moments, and wherein N is a positive integer greater than 1, M is a positive integer greater than 1, and N≥M;
- determining, by the device, a first value;
- determining, by the device, a first signal sending moment of the plurality of signal sending moments according to the first value;
- determining, by the device, whether a clear channel assessment (CCA) end moment is the first signal sending moment;
- and
- when the CCA end moment is the first signal sending moment, sending, by the device, a signal at the first signal sending moment.

A method, performed by a device, the method comprising:
- performing, by the device, seven clear channel assessments (CCAs) in two consecutive orthogonal frequency division multiplexing (OFDM) symbols, or performing four clear channel assessments (CCAs) in one orthogonal frequency division multiplexing (OFDM) symbol;
- and
- when an assessment result of a clear channel assessment (CCA) meets a signal sending condition, sending, by the device, a signal;
- and
- wherein a time length of at least two CCAs of the seven CCAs is 624 sampling time points, or wherein a time length of at least two CCAs of the four CCAs is 624 sampling time points.
