1. A downlink transmission method, comprising:
determining a time domain position of at least one first transmission resource in resources of a downlink data channel, wherein when the at least one first transmission resource is a plurality of first transmission resources, start positions of time domain positions of the plurality of first transmission resources are the same; and the at least one first transmission resource can be used to transmit downlink control information;
determining, based on the time domain position of the at least one first transmission resource and time domain positions of the resources of the downlink data channel, a condition satisfied by the at least one first transmission resource, wherein the condition satisfied by the at least one first transmission resource comprises a first condition or a second condition, the first condition is that a start position of the time domain position of the at least one first transmission resource is earlier than a first time domain position, and the second condition is that the start position of the time domain position of the at least one first transmission resource is the same as or later than the first time domain position, wherein the first time domain position is a position offset by a first time interval from a start position of the time domain positions of the resources of the downlink data channel, and the first time domain position is the same as or later than the start position of the time domain positions of the resources of the downlink data channel; and
determining a transmission mode of at least one of the downlink control information or the downlink data channel in the resources of the downlink data channel based on which of the first condition or the second condition is satisfied by the at least one first transmission resource.
