Wireless communication method and device for blind detection of downlink signals
摘要
說明書
A time-length for the terminal device to detect the preamble signal is greater than or equal to a length of P preamble signal symbols, and P is a positive integer. Alternatively, the time-length for the terminal device to detect the preamble signal is greater than or equal to a length of Q information segments of a preamble signal symbol, Q is a positive integer greater than or equal to 2.
It should be understood that if a time-length for detecting the preamble signal is variable, the minimum length for detecting the preamble signal needs to be specified, so that the terminal device can correctly receive the preamble signal.
Alternatively, an ending point for detecting the preamble signal may be an ending point of a downlink signal symbol.
Alternatively, a time-length for detecting the preamble signal is greater than or equal to a length of P preamble signal symbols. Alternatively, the time-length for detecting the preamble signal is greater than or equal to a length of P downlink signal symbols. Alternatively, the time-length for sending the preamble signal is greater than or equal to a length of Q information segments of the preamble signal symbol. P is a positive integer, and Q is a positive integer greater than or equal to 2.
Alternatively, the P, Q, or R may be predefined, or may be sent by the network device to the terminal device through one of an RRC signaling, a physical-layer signaling, and a MAC layer signaling.
