Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
For above-mentioned purpose, the feature and advantage that make the embodiment of the invention can be more obviously understandable, the embodiment of the invention is done further detailed explanation below in conjunction with accompanying drawing and embodiment.
With reference to figure 1, in the embodiment of the invention one, realize that the method for the transmission upstream data that the embodiment of the invention one is provided can may further comprise the steps:
Step 101: the terminal receives the indication signaling that network side sends, and said indication signaling is used for indicating terminal and sends upstream data according to the transmission sequence number TSN after expanding;
Wherein, said terminal is for supporting the multi-carrier terminal of multicarrier transmitting capacity, said indication signaling can pass through radio resource control (Radio Resource Control, RRC) mode that disposes of signaling is issued to the terminal; When network side need be set up the up enhancing of multicarrier when professional for the terminal; Then in RRC signaling configuration messages to the terminal; The MAC-es entity of notice terminal configuration, needing the TSN that uses is extended mode, so after business is set up; When terminal and network side carried out up enhancing Business Processing, the TSN sequence number length of use was the length of the TSN sequence number after the expansion; The transmission sequence number of said this MAC-es PDU of TSN sign; Said upstream data can be on up enhancing channel, the data that send to network side at the terminal, for example: media access control protocol data cell MAC PDU; In the present embodiment, the scope of said TSN is expanded, and therefore, variation has also taken place the length of upstream data; Wherein, the MAC-es entity is a MAC straton entity entrained in the MAC-e entity;
Wherein, The extended mode of the TSN of expansion can for: can support N (N is more than or equal to 2) carrier wave to send simultaneously if upstream data is sent at the terminal; The TSN maximum magnitude is 2 the inferior power of M (M is more than or equal to 6) so, the maximum of this TSN: satisfy the maximum product more than or equal to single carrier TSN scope and N;
Step 102: the terminal is sent upstream data according to said TSN to network side.
In the present embodiment, when the terminal will be sent upstream data to network side, at the MAC-es of end side entity; When MAC-d PDU being formed the first media access control protocol data cell MAC-es PDU; (DDI is the format identification (FID) through the configuration of RRC signaling for Data Description Indicator, DDI) information can also to generate the data description indication; Promptly can know the logical channel information of this MAC-es PDU with this DDI, and MAC-d PDU size information; When upstream data is sent at the terminal, can also identify the number of the MAC-d PDU that comprises among this MAC-es PDU with natural number N.
