The present invention discloses a feedback method and device for header compression feedback information: After RN is introduced in LTE-A system, user data transmitted at Un interface possesses a complex header structure with nesting double-IP containing GTP. Through application of the technical solution put forward by the embodiments of the present invention, different types of header compression feedback information carried in control PDU can be analyzed and processed with corresponding strategies according to the information in control PDU, thus effectively realizing separate compression and feedback for double headers and improving data transmission efficiency at Un interface. |
