The method includes: determine N1 slots based on a physical uplink shared channel, PUSCH resource, wherein the N1 slots are used to send a first redundancy version, RV of a PUSCH, and N1 is an integer greater than 1; send the 1st bit in the first RV on a second slot if the last bit in the first RV is sent on the last bit of a first slot, wherein the first slot is the (n1)th slot in the N1 slots, the second slot is the (n1+1)th slot in the N1 slots, n1=1, 2, . . . , or N1−1; and continuously send bits in the first RV if the last bit sent on the first slot is not the last bit in the first RV, wherein the last bit sent on the first slot and the 1st bit sent on the second slot are two adjacent bits in the first RV.
