[0044] In some embodiments, in a 5G NR system, for the set of symbols in a slot configured for a terminal to transmit a Physical Random Access Channel (PRACH) signal, part of the symbols (such as a subset of the above symbol set) may be indicated in the Downlink Control Information (DCI) for downlink transmission or as flexible symbols, or part of the symbols (such as a subset of the above symbol set) may be indicated in the DCI for receiving a Channel State Information-Reference Signal (CSI-RS) or a Physical Downlink Shared Channel (PDSCH) signal.

[0045] When signal transmissions conflict in the time domain, the terminal needs to cancel the transmission of the PRACH, which may lead to the failure of the terminal's random access.

[0046] The following describes in detail the signal transmission method, electronic device, and computer-readable storage medium of the embodiments of the present application with reference to the accompanying drawings.

[0052] In some embodiments, the above first time-domain resource is used by the terminal to transmit the above first signal.

[0053] In some embodiments, the above second time-domain resource is used by the terminal to receive the above second signal.

[0054] In some embodiments, the above first signal may be a Physical Random Access Channel (PRACH) signal.

[0055] In some embodiments, the above second signal may be a Channel State Information - Reference Signal (CSI-RS), or may also be a Physical Downlink Shared Channel (PDSCH) signal.

[0056] In some embodiments, the terminal may determine the first time-domain resource corresponding to the above first signal based on high-layer signaling (such as Radio Resource Control (RRC) signaling, etc.).

[0057] In some embodiments, the terminal may determine the second time-domain resource corresponding to the above second signal based on received Downlink Control Information (DCI).

[0058] In some embodiments, the above second signal is scheduled by DCI.

[0059] Step 202, determine that there is an overlap in the time-domain range between the above first time-domain resource and the above second time-domain resource, and cancel receiving the above second signal.

[0060] In some embodiments, the terminal can determine whether there is an overlap in the time-domain range between the above first time-domain resource and the above second time-domain resource.

[0061] In some embodiments, the terminal determines that there is an overlap in the time domain between the first time domain resource and the second time domain resource. In this case, the terminal can cancel the reception of the second signal.

[0062] In some embodiments, the second time domain resource may be a subset of the first time domain resource, or there is an overlap of some symbols between the second time domain resource and the first time domain resource, etc.

[0066] In each of the above embodiments of the present application, the first symbol of the first time domain resource may be outside the specified time range or may not be outside the specified time range.

[0067] That is, regardless of whether the terminal supports the partial cancellation ability and regardless of whether the transmission time of the PRACH (the first symbol of the transmitted PRACH) falls outside a certain time range (T proc,2 related to the last symbol of the control resource set CORESET), the terminal always chooses to transmit the PRACH signal and discards the reception of the CSI-RS or PDSCH signal.
