Patent number: 9106614Abstract: 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.Type: GrantFiled: October 28, 2011Date of Patent: August 11, 2015Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Lei Lu, Wenliang Liang, Dai Shi

Patent number: 8392616Abstract: A method for transmitting a header-compressed packet based on a retransmission mechanism is disclosed according to the present disclosure. The method mainly includes: a header compressor of a sending device obtains feedback information of a header-compressed packet in a transmission process; and the header compressor determines a state of the header compressor according to the feedback information, compresses a header for the packet according to the state of the header compressor, and sends the packet to a decompressor of a receiving device. According to the present disclosure, a header compression mechanism is combined with an automatic retransmission mechanism, so that the header compressor obtains feedback information of an automatic retransmission technology, and estimates the decompression information of the decompressor correctly, so as to change a state machine of the header compressor at proper time and improve transmission efficiency of the packet.Type: GrantFiled: March 30, 2012Date of Patent: March 5, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Gang Huang, Dai Shi, Lei Lu, Wenliang Liang
