1. A data transmission method, comprising:
receiving, by a centralized unit (CU), a first message from a distributed unit (DU), wherein the first message comprises a first transport block size (TBS) threshold, the first TBS threshold is useable for early transmission of uplink data, and the CU and DU are separated;
sending, by the CU, the first TBS threshold to a user equipment (UE), wherein the UE and DU are separated; and
receiving, by the CU, uplink data from the UE based on the first TBS threshold.
