A transmission method, applied to a user equipment, wherein the method comprises: receiving downlink transmissions; sorting ACK/NACK feedback information of the downlink transmissions according to Downlink Assignment Indexes, DAIs, corresponding to the downlink transmissions to obtain and transmit an ACK/NACK sequence to be fed back, wherein the DAIs cumulatively count the downlink transmissions at least in order of Transmission Reception Points, TRPs; characterized in that, the DAIs cumulatively count the downlink transmissions at least in order of Transmission Reception Points, TRPs, which comprises at least one of: when there are downlink transmissions in at least two different downlink times in a same configured or activated target, that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first and time domain later, wherein the target comprises at least one of the serving cell, carrier, bandwidth part; when the number of configured or activated targets is at least two, the DAIs cumulatively count the downlink transmissions in order of TRP first and frequency domain later, or the DAIs count independently in different targets and cumulatively count the downlink transmissions in order of TRPs corresponding to each target; when the number of configured or activated targets is at least two and there are downlink transmissions in at least two different downlink times that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first, frequency domain later and time domain last. receiving downlink transmissions; sorting ACK/NACK feedback information of the downlink transmissions according to Downlink Assignment Indexes, DAIs, corresponding to the downlink transmissions to obtain and transmit an ACK/NACK sequence to be fed back, wherein the DAIs cumulatively count the downlink transmissions at least in order of Transmission Reception Points, TRPs; characterized in that, the DAIs cumulatively count the downlink transmissions at least in order of Transmission Reception Points, TRPs, which comprises at least one of: when there are downlink transmissions in at least two different downlink times in a same configured or activated target, that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first and time domain later, wherein the target comprises at least one of the serving cell, carrier, bandwidth part; when the number of configured or activated targets is at least two, the DAIs cumulatively count the downlink transmissions in order of TRP first and frequency domain later, or the DAIs count independently in different targets and cumulatively count the downlink transmissions in order of TRPs corresponding to each target; when the number of configured or activated targets is at least two and there are downlink transmissions in at least two different downlink times that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first, frequency domain later and time domain last. when there are downlink transmissions in at least two different downlink times in a same configured or activated target, that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first and time domain later, wherein the target comprises at least one of the serving cell, carrier, bandwidth part; when the number of configured or activated targets is at least two, the DAIs cumulatively count the downlink transmissions in order of TRP first and frequency domain later, or the DAIs count independently in different targets and cumulatively count the downlink transmissions in order of TRPs corresponding to each target; when the number of configured or activated targets is at least two and there are downlink transmissions in at least two different downlink times that need to perform ACK/NACK feedbacks in a same uplink time, the DAIs cumulatively count the downlink transmissions in order of TRP first, frequency domain later and time domain last.
