alternatively, the first and second electrodes may be,
determining the position information of the second signal is independent of the position information of the first signal. For example, the time domain characteristic of the second signal is the same as the time domain characteristic of the first signal (for example, the SSB transmission period or offset is the same, or the number of SSBs in the SSB burst set is the same), and the frequency domain position of the second signal is independent of the frequency domain position of the first signal.
In this embodiment of the present application, the manner in which the signal relay device determines the location information of the second signal includes:

for example, the SSB-PRACH association of the signal relay device is consistent with the SSB-PRACH association of the base station.
Or the corresponding relation between the second signal and the third signal resource is independent of the corresponding relation between the first signal and the third signal resource; namely, the SSB of the signal relay device independently corresponds to the PRACH opportunity of the signal relay device;
for example, the SSB-PRACH association of the signal relay apparatus is notified by the base station or is kept consistent with the SSB-PRACH association of the base station.
It should be noted that the PRACH resource or SSB-PRACH association on the signal relay apparatus side is notified to the signal relay apparatus by the base station.
