Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Inventor had carried out labor to the technical scheme in background technology before realizing the embodiment of the present invention, as follows:
Need in MAC layer to be divided into MAC CE(Connection Element, linkage unit in the data of assembling) and logical channel data.Wherein MAC CE is the signaling data of MAC layer, and this partial data participates in the flow process of mac layer.The data of logical channel data for getting from the radio bearer buffer memory of layer 2 according to the size of Resourse Distribute, when comprising some RLC(Radio LinkControl in data assembling, wireless spread-spectrum technology) SDU(Service Data Unit, Service Data Unit) front portion data time, the data sectional of RLC will be produced, the segmentation of RLC data can increase the redundancy of PDU information to a certain extent, affects assembling and the decoding efficiency of RLC data.
In the process of logical channel data assembling, at least may there is the segmentation of RLC SDU data two links.Link one is that the Resourse Distribute size of logic channel in resource allocation process itself can not hold complete RLC SDU size, needs RLC SDU to carry out segmentation; Link two is in data assembling process, when the surplus resources size of Resource Block can not hold data on some logic channels, need again to carry out segmentation to the data of RLC SDU, in the surplus resources of this Resource Block, assemble size of data suitable on this logic channel.
Due to background technology scheme, in MAC layer data assembling process, MAC CE is assembled in maximum Resource Block.Then according to the size of Resource Block, the data of logic channel are assembled in each Resource Block successively according to priority order from high to low.Although the method controls simple, be easy to realize.But logical channel data can produce repeatedly RLC SDU segmentation when being assembled into multiple Resource Block, add the redundancy of data, reduce the efficiency of transmission of data.In addition, when MAC CE is assembled into the bad Resource Block of channel quality, data re-transmission repeatedly may be produced, have impact on the reaction time delay of network to terminal, such as: the MAC CE BSR(Buffer Status Report carrying out UE side surplus resources and report, buffer status report) assembling, the delay of transmission means the delay of network adjustresources mandate affects the transmission of data.
Based on above analysis, embodiments provide a kind of method of media access control layer ascending data assembling, as shown in Figure 1, comprising:

Wherein, the transmission success rate of hybrid automatic repeat-request goes for LTE-FDD(Long TermEvolution Frequent Division Duplex, Long Term Evolution frequency division multiplexing) and TD-LTE(TimeDivision Long Term Evolution, timesharing Long Term Evolution) system, ascending HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) the transmission success rate in nearest N transmission of Serving cell can be utilized as the reference parameter selecting MAC CE data assembling Resource Block.Terminal can upgrade the transmission success rate of Serving cell after each transmission of all Serving cells.
The measured value of Reference Signal Received Power goes in time-multiplexed TD-LTE system, utilizing the RSRP(Reference Signal Receiving Power of Serving cell, Reference Signal Received Power) measured value is as the Resource Block selecting MAC CE data assembling.
102: terminal selects service quality higher than the first resource block of preassigned in the available Resource Block got;
It should be noted that, because a Resource Block not necessarily can hold a MAC CE, therefore, when a Resource Block cannot hold MAC CE, first resource block can be two or more, as long as to be met above-mentioned " service quality is higher than preassigned " by the Resource Block selected just passable for these.
In general, can directly select Resource Block that service quality is the highest as first resource block.But, suboptimum Resource Block is selected also to be fine as alternative, it will be understood by those skilled in the art that, select the Resource Block of more high quality-of-service, guarantee MAC CE head that can be higher passes success rate, and therefore specifically still slightly lower the requirement so that service quality is the highest as standard, its result all can predict, therefore for which kind of specific standards select, the embodiment of the present invention will not uniqueness limit.Preferably, the Resource Block that directly selection service quality is the highest is as first resource block.

Circulation performs: select the logic channel i that Lmax is corresponding, and find in available resource block and can hold data unassembled in i and the minimum Resource Block of surplus resources, by data assembling unassembled in i in the Resource Block searched out, the value of data unassembled in i is set to 0, and upgrade the surplus resources of the Resource Block searched out, until the value of data unassembled in all logic channels is 0, and data stuffing is carried out to the Resource Block that there is surplus resources; Above-mentioned Lmax remains unassembled data maximums in all logic channels.
Further, the embodiment of the present invention additionally provides the processing scheme found less than Resource Block, as follows: said method, also comprises:
If do not search out Resource Block, then by Resource Block maximum for surplus resources in data assembling unassembled in i to all available Resource Block, the value of this Resource Block surplus resources is set to 0, and upgrades the value of data unassembled in i.
Two, above-mentioned with minimum fractionation number of times for principle, data assembling unassembled in logic channel is comprised to the above-mentioned available Resource Block got:
Perform following steps: if Lmin >=Rmax, by data assembling unassembled in logic channel corresponding for Lmin in Resource Block corresponding to Rmax, the R value of Resource Block corresponding for Rmax is set to 0, and upgrades the L value of Lmin counterlogic channel;
If Lmax < is Rmin, by data assembling unassembled in logic channel corresponding for Lmax in Resource Block corresponding to Rmin, the L value of Lmax counterlogic channel is set to 0, and upgrades the R value of the corresponding Resource Block of Rmin;
Otherwise, beat large order by R value retrieve from little in M Resource Block, the Resource Block m of data unassembled in logic channel n can be held if can retrieve, then by data assembling unassembled in n in m, and Ln value is set to 0, upgrades Rm; The Resource Block m of data unassembled in logic channel n can be held if do not retrieve, then by data assembling unassembled in n in Resource Block corresponding to Rmax, and the R value of Resource Block corresponding for Rmax is set to 0, upgrades Ln;
Wherein, above-mentioned M is the available Resource Block number got, and Rm is m Resource Block surplus resources size, and Rmax is surplus resources maximum in all available Resource Block, and Rmin is surplus resources minimum value in all available resource block; N is logic channel number, and Ln is that the n-th logic channel remains unassembled data volume, and Lmax remains unassembled data maximums in all logic channels, and Lmin remains unassembled data minimum value in all logic channels;
Until the L value of N number of logic channel is 0, if the L value of N number of logic channel is 0, the Resource Block not being 0 by R in M Resource Block carries out data stuffing.
