[0057] Example 4: When a first signal is detected at time-domain location t1, the terminal starts receiving a preamble information block at frequency-domain location t1+k2, where k2 is determined by one of one or more pre-specified values, terminal capability, the frequency-domain location of the first signal, and the frequency-domain location of the preamble information block.

[0058] Example 5: The terminal may start receiving the preamble information block at frequency domain location f2 when the first signal is detected and the indication information of the frequency domain location carried in the first signal is f2.

[0059] Example 6: When a first signal is detected and the indication information of the frequency domain location carried by the first signal is frequency domain location f2, the terminal can start receiving a preamble information block within a range of frequency domain locations (f2-k3, f2+k3), where the value of k3 can be predetermined, and when the terminal detects the first signal, the first signal is a signal consisting of at least one sequence.

[0060] Example 7: When a first signal is detected at frequency domain position f1 and the indication information of the frequency domain position carried by the first signal is frequency domain position f2, the terminal starts receiving a preamble information block within the range of frequency domain positions (f1-f2, f1+f2) or (f2-f1, f2+f1).

[0061] In example 8, the terminal begins receiving a preamble information block at time-domain position t1+k2 when a first signal is detected at time-domain position t1 and the indication of the time-domain position carried by the first signal is at time-domain position t2.

[0062] In Example 9, when a first signal is detected and the information carried in the first signal is index information, the terminal determines a position at which to start receiving the preamble information block based on the index information and the relationship between the index and the time-domain position of the preamble information block. Illustratively, as shown in Table 1, if the index in the index information is 1, the terminal starts receiving the preamble information block m1 milliseconds after receiving the first signal, if the index information is 2, the terminal starts receiving the preamble information block m2 milliseconds after receiving the first signal, and so on. [Table 1]

[0063] In Example 10, when a first signal is detected and the information carried by the first signal is index information, the terminal determines a position at which to start receiving the preamble information block based on the index information and the relationship between the index and the frequency domain position of the preamble information block. Illustratively, as shown in Table 2, if the index in the index information is 1, the terminal starts receiving the preamble information block at frequency domain position f1 after receiving the first signal, and if the index information is 2, the terminal starts receiving the preamble information block at frequency domain position f2 after receiving the first signal. [Table 2]

[0064] In Example 11, when a first signal is detected and the information carried in the first signal is index information, the terminal determines a position to start receiving the preamble information block based on the index information and the relationship between the index and the time-frequency domain position of the preamble information block. Illustratively, as shown in Table 3, if the index in the index information is 1, the terminal starts receiving the preamble information block at frequency domain position f1 after receiving the first signal, or starts receiving the preamble information block m1 milliseconds after receiving the first signal; if the index information is 2, the terminal starts receiving the preamble information block at frequency domain position f2 after receiving the first signal, or starts receiving the preamble information block m2 milliseconds after receiving the first signal; [Table 3]

[0065] Example 12: When a terminal detects a first signal at frequency domain position f1, the terminal begins receiving a preamble information block based on a predefined mapping relationship between the first signal and the preamble information block, where the relationship between the first signal and the preamble information block is the relationship between the frequency domain position of the first signal and the time-frequency domain position of the preamble information block, as shown in Table 4 below. The terminal begins receiving the preamble information block at a frequency domain position of f1 and a time domain position of m1 milliseconds after the first signal. [Table 4]

[0066] In Example 13, the terminal starts receiving a preamble information block if a first signal is detected but not detected within Z1 time units after the first signal is detected. When the terminal detects the first signal, it is assumed that the first signal is a 2ASK signal. FIG. 3 is a schematic diagram of a receiving position configuration between one first signal and a preamble information block according to an embodiment of the present application. As shown in FIG. 3, the terminal starts receiving a preamble information block if the first signal is not detected within Z1 time units after the first signal is received. Illustratively, the first signal is received by a separate module, and the preamble information block is received when the host is turned on.

[0067] In Example 14, if the terminal does not detect the first signal within Z2 time units after the host is turned on, it starts receiving the preamble information block. If the terminal detects the first signal, it assumes that the first signal is a 2ASK signal. Illustratively, the first signal is received by a separate module, and the preamble information block is received when the host is turned on.

[0068] In one embodiment, when a terminal receives a preamble information block, it assumes that one or more channels or signals in the preamble information block are transmitted periodically.

[0069] In one embodiment, if the preamble information block includes a second signal, the terminal first detects the second signal and identifies reception of other channels and / or signals in the preamble information block based on the detection result of the second signal.

[0094] In one embodiment, the base station may identify transmission of the preamble information block based on a mapping relationship between the first signal and the preamble information block, where the relationship between the first signal and the preamble information block may be predefined.

[0095] In one embodiment, the mapping relationship between the first signal and the preamble information block includes one or more of: a relationship between an index of the first signal and a frequency domain position corresponding to the preamble information block; or a relationship between an index of the first signal and a time domain position corresponding to the preamble information block; or a relationship between an index of the first signal and a time frequency domain position corresponding to the preamble information block; or a relationship between a frequency domain position of the first signal and a frequency domain position corresponding to the preamble information block; or a relationship between a frequency domain position of the first signal and a time frequency domain position corresponding to the preamble information block; or a relationship between a time domain position of the first signal and a time frequency domain position corresponding to the preamble information block; or a relationship between a time domain position of the first signal and a time frequency domain position corresponding to the preamble information block.

[0100] The time domain positions of both when the primary system message bearer channel shown in Figure 22 starts to be transmitted from the K-L+1th synchronization signal are just one schematic diagram, and both may be transmitted using other time domain positions. For example, assuming that the synchronization signal consists of two sub-synchronization signals, which are the first sub-synchronization signal and the second sub-synchronization signal respectively, the relationship between the time domain positions of both may be that the first sub-synchronization signal, the primary system message bearer signal and the second sub-synchronization signal, or the synchronization signal is located on the primary system message bearer channel.
