Abstract

The invention discloses a method and system for non-confirmed mode data transmission. The method comprises following steps: transmitting side establishes wireless logic channel information queue, performs segmental package for upper layer data packet according to bandwidth allocated by MAC layer, sends RLC PDU constituted by data packet fragment to MAC layer; receiving side establishes wireless loading logic channel information queue corresponding to the transmitting side, and checks the legality of the RLC PDU received from MAC layer, unpacks or un-segments to data packet fragment resolved from legal RLC PDU, discards data packet fragment unable to be recombined, submits the complete data packet to upper layer. The invention provides concrete implementing method for non-confirmed transmission mode.

Description

technical field [0001] The invention relates to the field of broadband mobile communication, in particular to a method and system for data transmission in a non-confirmation mode. Background technique [0002] The Third Generation Partnership Project (3 rd Generation Partnership Project, 3GPP) is an international standardization organization. As a leader in the field of traditional mobile communications, whether it is to promote the industrialization of new technologies, or to cope with the fierce technological competition in the industry, and to maintain its leading position in the field of mobile communications, 3GPP is required to accelerate the adoption of the third generation with higher transmission rates. Research and standardization process of mobile communication evolution technology. In November 2004, the 3GPP passed the project establishment work on 3G Long Term Evolution (Long Term Evolution, LTE). The LTE system improves and enhances the air access technolog...
