Wireless communication method and device for blind detection of downlink signals
摘要
說明書
In some embodiments, the preamble signal symbol is the first preamble signal symbol which is located behind the time-point at which the channel detection succeeds.
In some embodiments, the preamble signal symbol includes a first cyclic prefix (CP) and an information segment; and the first time-point includes a starting point of the first CP in the preamble signal symbol.
In some embodiments, the preamble signal symbol includes a second CP and M information segments, wherein M is a positive integer greater than or equal to 2; and the first time-point includes a starting point of the second CP or any one of the M information segments in the preamble signal symbol.
In some embodiments, the method further includes sending an occupying signal or 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.
In some embodiments, the first time-point includes a starting point of a downlink signal symbol configured for sending the downlink signal.
In some embodiments, the method further includes sending the downlink signal on the carrier from a second time-point, after the preamble signal is sent, wherein the second time-point is a starting point of the downlink signal symbol.
