摘要：
Embodiments of the present invention provide a data transmission method and apparatus. ROHC packets that use a same Context ID are encapsulated into MAC PDU, wherein the MAC PDU is formed by a MAC PDU packet header and a MAC PDU payload. The Context ID of the ROHC packets is carried in the MAC PDU packet header, and the Context ID is not carried in the ROHC packets. The MAC PDU is sent. In this way, transmission resources are saved, and transmission efficiency is improved.
