1. A downlink transmission sending method, applicable to a base station, comprising:
for a downlink transmission in N repetitions, in response to determining that a repetition overlaps with second transmission resources of one or more synchronization signal blocks,
canceling sending the downlink transmission on first transmission resources, delaying sending the M repetitions corresponding to the first transmission resources, so that the downlink transmission comprises a total of N repetitions; wherein M is a positive integer less than N; or
sending the downlink transmission by puncturing the first transmission resources;
wherein the first transmission resources are for the repetition and overlap with the second transmission resources of the one or more synchronization signal blocks over at least one resource element (RE);
wherein sending the downlink transmission by puncturing the first transmission resources comprises canceling sending a part of the downlink transmission which is mapped onto one or more overlapped resources between the first transmission resources and the second transmission resources; and
wherein N is a positive integer equal to or greater than 2.
