1. A data transmission method, wherein the method comprises:
sending, to a communications apparatus, information about a repetition quantity (R1) corresponding to a maximum transport block size (Tmax) allowed to be used to transmit data;
determining, based on R1, a cyclic parameter (L) that indicates content carried in each of a plurality of time units to which a transport block used to transmit data is mapped is repeated in L consecutive time units, wherein a transport block size actually used to transmit the data (Ts) is less than Tmax; and
receiving the data based on the cyclic parameter (L),
wherein the determining a cyclic parameter (L) comprises:
when R1≥8, L=min (K,┌R1/2┐), wherein K is a preset constant, and ┌ ┐ represents rounding up; or
when R1<8, L=1.
