Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Method embodiment
According to embodiments of the invention, the system of selection of a kind of TFC is provided, this method is applicable to TD-SCDMA or WCDMA system.Fig. 1 is the flow chart according to the system of selection of the TFC of the embodiment of the invention, and as shown in Figure 1, this method comprises that following step S102 is to step S106:
Step S102, for each radio frames, the MAC layer defines data transmission channel to be passed according to the buffer load situation of obtaining and does not have the transmission channel of transfer of data, promptly, to whether there being transfer of data to provide indication on each transmission channel, wherein, the buffer load situation is the buffer load situation on all logic channels that are mapped on the transmission channel that can carry out the upstream data transmission in this radio frames.
Particularly, all whether free of data is to be transmitted to judge all logic channels of transmission channel bearing, if judged result is for being to determine that then this transmission channel is the transmission channel that does not have data to be passed, if judged result determines that for not this transmission channel is the transmission channel that has data to be passed.Wherein, do not have the transmission channel of transfer of data not participate in the TFC selection, but TFC is selected to provide constraints.
Step S104, the MAC layer filters transport format combination set according to the transmission channel that does not have the transmission of data needs, dwindles range of choice.
Step S106, filters transport format combination set by selecting to have the transformat of data transmission channel to be passed once more according to the priority of logic channel, selects transformat combination.
Particularly, from all logic channel medium priorities the highest data logic channel to be passed arranged, what have one by one that data logic channel to be passed selects that it shines upon has a transformat on the data transmission channel to be passed, selecting simultaneously, transport format combination set is filtered further, transport format combination set is filtered with realization.
Wherein, from priority the highest have data logic channel to be passed to begin to select the transformat of its transmission channel that shines upon the time, data logic channel to be passed is arranged is that its having of shining upon has on the data transmission channel to be passed on the minimum transmission channel that logic channel or its shone upon of data logic channel medium priority to be passed if priority is the highest, when having only this logic channel to have data to send, then after this logic channel has been selected transformat, result according to this selection, transport format combination set is filtered further the range of choice when dwindling transport format combination selection next time.
When if the last item has data logic channel to be passed to select transformat, more than one transformat combination is still arranged in the transport format combination set that filtration obtains, then (promptly according to the minimum principle of code check, according to code check alignment) filter, select lower that of code check as final result.That is, determine the transformat combination of the minimum transformat combination of code check for selecting.
If data logic channel to be passed is arranged in the process of selecting transformat, filtering in the transport format combination set that obtains has a transformat combination, then determines the transformat combination of this transformat combination for selecting.That is to say that find to have only an element in the transport format combination set if this selects to finish the back, expression has been selected to finish, the pairing transformat combination of this element is exactly a final result, can finish the transport format combination selection process.
Need to prove, for for the second time and the above for the second time transformat combination of selecting, the TFC selection result that the MAC layer was selected according to the last time and do not have the transmission channel of data needs transmission that transport format combination set is filtered.
By this embodiment, only participate in the transmission channel selected and the quantity of logic channel to having data logic channel to be passed to select transformat on its transmission channel that shines upon, having dwindled greatly, simplified operation.Though have the transmission channel of transfer of data and TTI border not to participate in the TFC selection, to the transport format combination set filtration with the unmatched transmission channel of this frame.This filtration can be carried out take the selection transformat combination according to every logic channel buffering area before, can reduce the number of transformat combination in the transport format combination set greatly like this, thereby had accelerated the speed of selecting.
Be described in detail below in conjunction with the implementation procedure of example the embodiment of the invention.
Fig. 2 is the detail flowchart according to the system of selection of the TFC of the embodiment of the invention, as shown in Figure 2, comprises that following step S202 is to step S224:
Step S202, each radio frames, the MAC layer receives radio frames and interrupts, and reads the Connection Frame Number (Connect Frame Number abbreviates CFN as) of present frame; Transmission channel is filtered, transmission channel is divided into participates in that TFC selects and cannot participate in that TFC selects, be divided into two tables.The method of filtering is whether the TTI border of investigating transmission channel meets current frame number.Thinking of meeting can participate in that this TFC selects, otherwise thinks that cannot participate in this TFC selects.The transformat of not participating in the transmission channel that this TFC selects must be kept the same with previous frame, thereby this selection is exerted an influence.
Step S204 obtains all buffer areas of participating in all logic channels that shone upon on the transmission channel of this TFC selection and takies situation.Need transmission if participate in the equal free of data of all logic channels of carrying on the transmission channel that this TFC selects, then think this transmission channel free of data transmission, the transformat that should select free of data to send.The same list of logical channels that transfer of data is arranged of arranging that produces of this process according to priority of logical channels.
Step S206, make transformat combination filtering model, the filtercondition that has reflected this selection in the model, will keep the transformat of the transmission channel last time of not participating in this transport format combination selection on the one hand, the transformat that also will guarantee the transmission channel correspondence of free of data transmission on the other hand is the transformat that free of data sends.
Step S208 filters transport format combination set according to transformat combination filtering model, and the inconsistent transformat combination of corresponding transmission channel format and model is thought nonconforming combination, should filter out from set.Filter through this, produce the active set of initial selected.
Step S210, the logic channel of arranging according to priority of logical channels that limit priority in the data list of logical channels to be passed is arranged that generates from step S204 begins the TFC selection.This step checks whether traveled through all logic channels after transformat is selected to finish on a logic channel at every turn simultaneously, judge whether that traversal finishes, if judged result is for being, execution in step S220 then, if judged result is not, then execution in step S212.
Step S212 according to the load and the RLC entity patterns information of current logic channel, selects the transformat on the transmission channel of its mapping.The rule of selecting is the configuration that the RLC entity is satisfied in first requirement, promptly, at affirmation mode (Acknowledged Mode, abbreviating AM as) RLC size (SIZE) must and dispose identical under the pattern, guarantee simultaneously to pass under the data conditions as far as possible more, do not make rlc layer produce and fill protocol Data Unit (Protocol Data Unit abbreviates PDU as) (have only RLC header and filling bit (bit), and do not have the RLC PDU of real data).Need simultaneously to guarantee that the transformat of selecting must be included in the transformat combination in the transport format combination set.Meet the transformat combination at the transformat place of above-mentioned requirements, be considered to satisfactory transformat combination.
Step S214, check this logic channel many to single (many logic channels are mapped in a form on the transmission channel) situation under, whether be to be mapped in the minimum logic channel of priority on this transmission channel; Or it is single to a unique logic channel on the transmission channel under list (logic channel is mapped in a form on the transmission channel) situation; If satisfy any in the above-mentioned condition, represent that then the transformat on this transmission channel is selected to finish execution in step S216, otherwise execution in step S218.
Step S216 filters transport format combination set on the basis of this transmission channel selection result, thereby generates a new effective subset.
Step S218 checks element number in the newly-generated transport format combination set, if 1 expression has only an effective element, then finishes selection course, directly execution in step S224; Otherwise return execution in step S210.
Step S220 checks whether the number of effective element in the final TFCs set is 1.Be 1 execution in step S224, otherwise, execution in step S222.
Step S222, all TFC in the final TFCs set calculate average bit rate, and Calculation Method is the bit number removal that can transmit with each transmission channel TTI with correspondence, then with results added.The transformat combination that code check is lower is an optimum.
Step S224 returns selection result.
