說明書
Alternatively, the first time-point includes a starting point of the second CP or one of the M information segments in the preamble signal symbol.
Alternatively, the communication unit 1120 is further configured for sending an occupying signal on the carrier from a time-point at which the channel detection succeeds to the first time-point, in response to the first time-point not being the time-point at which the channel detection succeeds.
Alternatively, the communication unit 1120 is further configured for sending a CP of the preamble signal on the carrier from the time-point at which the channel detection succeeds to the first time-point, in response to the first time-point not being the time-point at which the channel detection succeeds.
Alternatively, the first time-point includes a starting point of a downlink signal symbol.
Alternatively, the communication unit 1120 is further configured for sending a downlink signal on the carrier from a second time-point, after the preamble signal is sent.
Alternatively, the second time-point is a starting point of a downlink signal symbol.
Alternatively, a preamble signal symbol corresponds to a first subcarrier spacing; and the first subcarrier spacing is a subcarrier spacing corresponding to the downlink signal; or the first subcarrier spacing is a subcarrier spacing indicated by at least one of a radio resource control (RRC) signaling, a physical-layer signaling, and a MAC-layer signaling; or the first subcarrier spacing is a predefined subcarrier spacing.
