Abstract

A communication method and a related apparatus for header compression by using an automatic retransmission mechanism are disclosed. The method comprises determining with a receive end parameters required for performing header compression and an ARQ through negotiation, constructing a lower-layer PDU that comprises header compression information, and sending the PDU to a receive end. By using methods provided in the embodiments of the present invention, combination of a header compression mechanism and an ARQ mechanism may be implemented, thereby improving header compression efficiency and accuracy, and saving air interface resources.
