Description
Technical field
The present invention relates to the communications field, in particular to a kind of priority processing method.
Background technology
3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, abbreviate LTE as) wave point medium access control (the Media Access Control of " universal land radio access web of evolution (the Evolved Universal Terrestrial Radio Access Network; abbreviate E-UTRAN as; form; therefore also can be called base station eNB) " of system by base station eNB, abbreviate MAC as) protocol layer, there is scheduling/processed (Scheduling/Priority handling) entity, wherein, dynamic dispatching (Dynamic scheduling) and semi-persistent scheduling (or being called semi-persistent scheduling) (Semi-persistent Scheduling) are supported in scheduling.
Scheduling is used to descending/Uplink Shared Channel to distribute physical resource, and the downlink or uplink scheduling feature is carried out by different scheduler (Scheduler).For at subscriber equipment (User Equipment, abbreviate UE as) between shared resource, scheduler need be considered the traffic carrying capacity (Traffic Volume) and service quality (the Quality of Service:QoS) demand of each UE and relevant radio bearer (Radio Bearer abbreviates RB as); Also may consider the radio condition of UE, described radio condition can be discerned according to the measurement that eNB measures or UE reports.Wireless resource allocation is effective at one or more Transmission Time Intervals (Transmission Timer Interval abbreviates TTI as), for the latter's situation, and information such as distribution time that need be extra, distribution repetition factor.Distributing radio resource is divided into descending distribution (DL assignment) and two kinds of situations of uplink authorization (UL grant), is respectively applied for descending and uplink scheduling, and descending distribution and uplink authorization refer to downlink resource and ascending resource respectively.Institute's assigned radio resource comprises information such as Physical Resource Block (Physical Resource Block abbreviates PRB as) and MCS.
Transmission for Uplink Shared Channel, uplink authorization distributes according to UE rather than RB, after UE receives above-mentioned mandate, principle and the algorithm of handling according to priority of logical channels distributes UL grant between different logic channel (Logical channel) again, thereby determine which logic channel sends data, and send how many data, thereby the medium access control Service Data Unit of Different Logic channel (Media Access Control Service Data Unit, abbreviate MAC SDU as) be multiplexed with a media access control protocol data unit (Media Access Control Protocol Data Unit, abbreviate MAC PDU as) carry out up transmission, wherein supporting multiple-input, multiple-output (Multiple Input Multiple Output, abbreviate MIMO as) under the situation of antenna, two MAC PDU may be arranged simultaneously at each TTI.The priority of logical channels processing capacity is positioned at the MAC layer of UE, is used for upstream rate control (therefore being also referred to as the upstream rate controlled function), shares with the ascending resource between the management RB, is applied to new transfer of data (new transmission).Radio resource control (Radio Resource Control, abbreviate RRC as) (value of priority increases progressively to dispose the priority of each logic channel, then priority is successively decreased), preferential bit rate (Prioritized Bit Rate abbreviates PBR as) and barrel size time interval BSD parameters such as (Bucket Size Duration).
The principle that upstream rate controlled function or priority of logical channels are handled is as follows: UE serves radio bearer in the following order: one, all RB according to priority successively decrease order until satisfying its PBR; Two, all RB order assignment surplus resources that according to priority successively decreases.If a plurality of RB dispose identical priority, then UE is equal to and treats these RB.If all PBR are set to 0, then the first step is skipped, and all RB are according to the transmission of the priority orders Resources allocation of strictness: UE maximization high-priority data.ENB distributes to the whole uplink authorization of UE to control the aggregate maximum bit rate (Aggregate Maximum bit rate abbreviates AMBR as) that upstream rate is no more than UE by restriction.
Be the principle that realizes that above-mentioned priority of logical channels is handled, LTE adopts token bucket algorithm, and the basic skills of this algorithm is as follows:
UE safeguards variable Bj (Bj is the assigned token value of logic channel j) for each logic channel j; Bj is initialized as 0 when logic channel is set up, at each TTI, Bj multiply by the TTI time interval according to PBR and increases progressively.So at each TTI, above-mentioned formula is:
Bj＝Bj+PBR×TTI?duration；
Bj can not surpass a bucket size, if Bj is during greater than the bucket size then be set to a barrel size.So above-mentioned formula is:
If?Bj＞Bucket?Size；then?Bj＝Bucket?Size；
Bucket size Bucket Size=PBR * BSD of logic channel j wherein.
When UE carried out new transmission, the priority of logical channels processing procedure was as follows:
Step 1: for the logic channel of each Bj＞0, the order assignment resource of successively decreasing according to priority; (if the PBR of certain RB is configured to unlimited infinity, and then UE should all can send data among this RB resource allocation earlier, could distribute to other low priorities RB to surplus resources to satisfy its PBR then);
Step 2:UE deducts the overall dimensions of the medium access control Service Data Unit that generates among the logic channel j in the step 1 with Bj.Be Bj=Bj-total size of MAC SDU of logical channel j; Wherein Bj can be negative value.
Step 3: if also have surplus resources, then depleted in strict accordance with priority of logical channels data or the uplink authorization of order (ignoring the value of Bj) Resources allocation in logic channel that successively decrease, promptly wherein any one condition satisfies earlier.The logic channel that is configured to equal priority is equal to be treated.
In above-mentioned scheduling process, UE also should follow following principle:
(RLC SDU comprises the RLC SDU of part transmission or the rlc protocol data cell (RLC PDU) of re-transmission, and then UE should be to above-mentioned RLC SDU segmentation if surplus resources can hold whole Radio Link control Service Data Unit;
If UE need carry out segmentation to the RLC SDU from certain logic channel, the size that then should maximize this section is to fill the uplink authorization that is distributed as far as possible;
UE should maximum data transmission.
UE should not send the data in the pairing logic channel of the RB that is suspended.
Fig. 1 handles and the multiplexing process schematic diagram of MAC PDU according to the priority of logical channels of correlation technique, and as shown in Figure 1, logic channel 1 has limit priority, and at first, available resources are used for logic channel 1 to its PBR; Select logic channel 2,3 respectively to its PBR then; If also have available resources, then the 2nd take turns distribution according to the priority of logical channels order from logic channel 1, exhaust less than more multidata or available resources to logic channel 1, carry out successively.The MAC protocol layer is according to said process, calculate the size of the RLC PDU that each logic channel can send, and this information indicated to rlc protocol layer (RLC PDU and MAC SDU one by one corresponding), rlc layer generates RLC PDU according to above-mentioned information at each logic channel and is submitted to the MAC layer, be multiplexed with MAC PDU by the MAC layer, MAC PDU further is submitted to physical layer and is generated the upward transmission of the capable physically shared channel (PUSCH) of transmission block (TB).
In order to satisfy the demand that growing big bandwidth high-speed mobile inserts, third generation partnership project (Third Generation Partnership Projects, abbreviation 3GPP) releases senior Long Term Evolution (Long-Term Evolution Advanced is called for short LTE-Advanced or LTE-A) standard.LTE-A adopts series of new techniques that frequency domain, spatial domain are expanded on the LTE basis, to reach purposes such as improving the availability of frequency spectrum, increase power system capacity.Wherein carrier aggregation technology can the two or more component carriers of polymerization (Component Carrier) to support wideer frequency band, for example, arrive 100MHz and spectrum aggregating.UE is reception/transmission data on one or more component carriers simultaneously, can be configured in descending/different numbers of up gathering and have the component carrier of different bandwidth.Corresponding one of each component carrier mixes automatic repeat requests (HARQ) entity and shared transmission channel.Downlink or uplink for each component carrier sends the control signaling that has independent Physical Downlink Control Channel (PDCCH) indexed resource to distribute respectively, PDCCH may indicate resource allocation on the well-behaved loading gage ripple or the resource allocation on other component carrier, and 0～3bit indication component carrier identification information is arranged on the PDCCH.Certain TTI in uplink scheduling, each component carrier that is scheduled as up transmission may receive different uplink authorizations respectively, the upstream data of UE sends and will carry on these uplink authorizations respectively, so the priority of logical channels processing procedure needs new principle and which component carrier algorithm carries on the data of determining which logic channel, and how many data corresponding component carrier carry respectively, carries out up transmission thereby generate MAC PDU respectively at the component carrier that each is scheduled as up transmission.

If the resource on the corresponding component carrier can not satisfy its PBR resource requirement, then select the available resources on the next suitable component carrier (that is, the next component carrier of the component carrier of current correspondence), until satisfying the required resource of its PBR;
For the higher priority logic channel (promptly, priority is higher than the logic channel of the logic channel of other resource to be allocated), if the available resources on the corresponding component carrier can not satisfy the transmission of its data, then select next suitable component carrier (promptly, the next component carrier of the component carrier of current correspondence) available resources on, send resource requirement or do not have available resources until satisfying its data, promptly the uplink authorization of the data in logic channel or selected one or more component carriers is depleted; The rest may be inferred; Available resources on the suitable component carrier refer to the surplus resources of respective component carrier wave after satisfying its counterlogic channel PBR resource requirement and higher priority logic channel resource requirement;

According to the method for the resource on the suitable component carrier of above-mentioned distribution, all logic channels successively decrease according to priority and select corresponding suitable component carrier in proper order respectively, and distribute available resources to send to maximize its data on the component carrier of correspondence;
Data on certain logic channel should be used the least possible MAC PDU carrying, and promptly the data on certain logic channel should send on the least possible component carrier, to reduce fragmentation overhead and header overhead; Available resources on the corresponding component carrier refer to the surplus resources of resource after the data of PBR that preferentially satisfies logic channel and higher priority logic channel send on this component carrier;
When selecting next suitable component carrier, the QoS requirement of Radio Resource conditional sum logic channel of paying the utmost attention to component carrier is adaptive; Perhaps pay the utmost attention to the pairing component carrier of lower priority logic channel (that is, priority is lower than the logic channel of other priority of logical channels); Pay the utmost attention to perhaps that UL grant can satisfy or send the component carrier of demand near its data;
According to the method for the resource on the suitable component carrier of above-mentioned distribution, all logic channels obtain the number of the medium access control Service Data Unit (MAC SDU) that can send and the payload size of MAC SDU respectively on each component carrier; The payload size of MAC SDU deducts the size of its corresponding MAC head for logic channel assigned resource sum on the respective component carrier wave.The number and the size information thereof of the wireless link control protocol data cell (RLC PDU) that each logic channel of media access control protocol layer indication radio link control layer can send on each component carrier; RLC PDU and MAC SDU are corresponding one by one.Rlc layer receives above-mentioned indication information, generates the RLC PDU of corresponding number and size at each logic channel, be submitted to the MAC layer carry out as MAC SDU multiplexing, thereby on corresponding component carrier, generate corresponding M AC PDU.
According to the method for the resource on the suitable component carrier of above-mentioned distribution, UE is the multiplexing respectively MAC SDU from each logic channel on each component carrier, generates MAC PDU and is submitted to physical layer; Physical layer further generates on the capable physically shared channel (PUSCH) of transmission block (Transport Block abbreviates TB as) and sends.
Wherein, above-mentioned all logic channels all logic channels that are Bj＞0.
Wherein, all resources include the ascending resource of all component carriers of ascending resource, and wherein, above-mentioned ascending resource is also referred to as uplink authorization.
Be described in detail below in conjunction with the implementation procedure of example the embodiment of the invention.
Fig. 2 is according to the schematic diagram of the embodiment of the invention 1, is described as follows:
Be provided with three logic channel RB1, RB2, RB3, its priority reduces successively, and its PBR configuration is respectively X, Y, Z.At certain TTI, its corresponding Bj (j equals 1,2,3 respectively) is respectively DATA1, DATA2, DATA3.
Be provided with three component carriers that are scheduled as up transmission, be respectively U, V, W in certain TTI authorized resource.
Service quality (Quality of Service according to the Radio Resource condition adaptation, logic channel of component carrier, abbreviate QoS as) principle of demand, perhaps according to the priority orders of default component carrier and the corresponding principle of priority orders of logic channel, the order that these three logic channels according to priority successively decrease is selected corresponding suitable component carrier respectively, and determined mapping relations are: RB1 corresponding to component carrier 1, RB2 corresponding to component carrier 2, RB3 corresponding to component carrier 3.
All logic channels successively decrease to calculate respectively on the component carrier of correspondence in proper order according to priority and can satisfy its PBR resource requirement, in the drawings for being designated
Operation.So the resource that RB1 is assigned on the component carrier 1 is X; The resource that RB2 is assigned on the component carrier 2 is Y; The resource that RB3 is assigned on the component carrier 3 is Z.
Through above-mentioned steps, the Bj of each logic channel is updated to:
The B1=DATA1-X of RB1;
The B2=DATA2-Y of RB2;
The B3=DATA3-Z of RB3;
Wherein Bj can be negative value.
All logic channels successively decrease according to priority and calculate the available resources that can be assigned in proper order on the component carriers of correspondence, in the drawings for being designated
Operation.So the available resources that RB1 is assigned on the component carrier 1 are U-X; Available resources on the component carrier 2 that KB1 is assigned to are that DATA1-U is (because the resource of component carrier 1 can not send the total data on the RB1, the remaining data of RB1 also needs the resource of DATA1-U, then select the available resources on the next suitable component carrier, selected the available resources on the component carrier 2 in this example.Because the priority of RB1 is higher than RB2, therefore the available resources priority allocation on component carrier 2 is given the remaining data of RB1 to satisfying the resource that its remaining data sends).The available resources that RB2 is assigned on the component carrier 2 are V-Y-(DATA1-U); The available resources that RB2 is assigned on the component carrier 3 are that DATA2-V is (because the resource of component carrier 2 can not send the total data on the RB2, the remaining data of RB2 also needs the resource of DATA2-V, then select the available resources on the next suitable component carrier, selected the available resources on the component carrier 3 in this example.Because the priority of RB2 is higher than RB3, therefore the available resources priority allocation on component carrier 3 is given the remaining data of KB2 to satisfying the resource that its remaining data sends).The available resources that RB3 is assigned on the component carrier 3 are W-Z-(DATA2-V), because this moment, available resources were not enough to send all data of RB3, be the situation that resource has exhausted earlier, the EO of Resources allocation then, certain TTI was scheduled after the remaining data of RB3 was waited for.
According to the aforesaid operations result, the resource that each logic channel is distributed on each component carrier respectively addition respectively (the resource addition that on component carrier 1, is distributed as RB1, the resource addition that RB1 is distributed on component carrier 2, the rest may be inferred), can obtain the size of the MAC SDU that each logic channel generated on corresponding each component carrier; The size of described MAC SDU is the size that described logic channel assigned resource sum on the respective component carrier wave deducts its corresponding MAC head.
In this example, the MAC PDU on component carrier 1 comprises 1 MAC SDU, and by the data on the RB1 are generated, the payload of MAC SDU size deducts its corresponding MAC head length degree for U, and promptly the MAC PDU of Sheng Chenging deducts the length of MAC PDU; This MAC SDU resource requirement is that the resource of the satisfied PBR1 that distributes the first round adds that second takes turns the available resources on this component carrier of being distributed.The MAC PDU that generates on component carrier 2 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB1, and its payload size deducts corresponding MAC head length degree for DATA1-U; Another one MAC SDU is the data of RB2, the payload size deducts corresponding MAC head length degree for V-(DATA1-U), and this MAC SDU resource requirement adds that by the resource of the satisfied PBR2 that the first round distributes second takes turns the available resources on this component carrier of being distributed.The MAC PDU that generates on component carrier 3 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB2, and its payload size deducts corresponding MAC head length degree for DATA2-V; Another one MAC SDU is the data of RB3, the payload size deducts corresponding MAC head length degree for W-(DATA2-V), and this MAC SDU resource requirement adds that by the resource of the satisfied PBR3 that the first round distributes second takes turns the available resources on this component carrier of being distributed.
The number and the size information thereof of the wireless link control protocol data cell (RLC PDU) that each logic channel of media access control protocol layer (MAC) indication radio link control layer (RLC) can send on each component carrier; Described RLC PDU and above-mentioned MACSDU are corresponding one by one.Rlc layer receives above-mentioned indication information, generates the RLC PDU of corresponding number and size at each logic channel, be submitted to the MAC layer carry out as MAC SDU multiplexing, thereby on corresponding component carrier, generate corresponding M AC PDU.
Need to prove that in above-mentioned scheduling process, when calculating the resource that certain logic channel can distribute on its selected component carrier, UE also follows the basic principle of token bucket algorithm among the LTE.
Wherein, in concrete realization, consider the available situation of traffic carrying capacity, service feature and the resource of logic channel, the PBR of certain logic channel not necessarily is satisfied at each TTI, also may less than or greater than PBR, therefore be the average result in the certain hour, promptly can satisfy the PBR demand of this logic channel within a certain period of time according to the effect that above-mentioned dispatching algorithm reached.

Be provided with three component carriers that are scheduled as up transmission, be respectively U, V, W in certain TTI authorized resource.
As total resource pool, all logic channels successively decrease the order assignment resource until satisfying its PBR resource requirement, in the drawings for being designated according to priority with the resource sum on all component carriers
Operation.So the resource that KB 1 is assigned to is X; The resource that RB2 is assigned to is Y; The resource that RB3 is assigned to is Z.
Through above-mentioned steps, the Bj of each logic channel is updated to:
The B1=DATA1-X of KB1;
The B2=DATA2-Y of RB2;
The B3=DATA3-Z of RB3;
Wherein Bj can be negative value.
All logic channels are according to the priority order assignment remaining available resource of successively decreasing, and data or resource in logic channel are depleted, in the drawings for being designated
Operation.So the available resources that KB1 is assigned to are DATA1-X; The available resources that RB2 is assigned to are DATA2-Y; The available resources that RB3 is assigned to are U+V+W-DATA1-DATA2-Z (available resources can not be held all data of RB3).
According to aforementioned calculation, obtain its PBR resource requirement and remaining available resource that satisfy that all logic channels can be assigned to respectively.
Principle according to service quality (QoS) demand of the Radio Resource condition adaptation, logic channel of component carrier, perhaps according to the priority orders of default component carrier and the corresponding principle of priority orders of logic channel, the order that these three logic channels according to priority successively decrease is selected corresponding suitable component carrier respectively, and determined mapping relations are: KB1 corresponding to component carrier 1, RB2 corresponding to component carrier 2, RB3 corresponding to component carrier 3.
All logic channels successively decrease according to priority and distribute it according to the assigned resource of aforementioned calculation, in the drawings for being designated in proper order respectively on the component carrier of correspondence
Operation.In this example, the resource that RB1 is assigned on the component carrier 1 is U; Resource on the component carrier 2 that KB1 is assigned to is DATA1-U.The resource that RB2 is assigned on the component carrier 2 is V-(DATA1-U); The resource that KB2 is assigned on the component carrier 3 is DATA2-V.The available resources that RB3 is assigned on the component carrier 3 are W-(DATA2-V), because this moment, available resources were not enough to send all data of KB3, be the situation that resource has exhausted earlier, the EO of Resources allocation then, certain TTI was scheduled after the remaining data of KB3 was waited for.
According to the aforesaid operations result, can obtain the size of the MAC SDU that each logic channel generated on corresponding each component carrier; The size of described MAC SDU is the size that described logic channel assigned resource on the respective component carrier wave deducts its corresponding MAC head.
In this example, the MAC PDU on component carrier 1 comprises 1 MAC SDU, and by the data on the RB1 are generated, the payload of MAC SDU size deducts its corresponding MAC head length degree for U, and promptly the MAC PDU of Sheng Chenging deducts the length of MAC PDU.The MAC PDU that generates on component carrier 2 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB1, and its payload size deducts corresponding MAC head length degree for DATA1-U; Another one MAC SDU is the data of RB2, and the payload size deducts corresponding MAC head length degree for V-(DATA1-U).The MAC PDU that generates on component carrier 3 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB2, and its payload size deducts corresponding MAC head length degree for DATA2-V; Another one MAC SDU is the data of RB3, and the payload size deducts corresponding MAC head length degree for W-(DATA2-V).
The number and the size information thereof of the wireless link control protocol data cell (RLC PDU) that each logic channel of media access control protocol layer (MAC) indication radio link control layer (RLC) can send on each component carrier; Described RLC PDU and above-mentioned MACSDU are corresponding one by one.Rlc layer receives above-mentioned indication information, generates the RLC PDU of corresponding number and size at each logic channel, be submitted to the MAC layer carry out as MAC SDU multiplexing, thereby on corresponding component carrier, generate corresponding M AC PDU.
Fig. 4 shows the schematic diagram according to the embodiment of the invention 3, is described as follows:
This example has illustrated according to the resource on the selected component carrier of adaptive principle of logic channel and component carrier can not satisfy processing procedure under the PBR resource requirement situation of high priority logic channel.
Be provided with two logic channel RB1, RB2, its priority reduces successively, and its PBR configuration is respectively X, Y.At certain TTI, its corresponding Bj (j equals 1,2 respectively) is respectively DATA1, DATA2.
Be provided with two component carriers that are scheduled as up transmission, be respectively U, V in certain TTI authorized resource.
Principle according to service quality (QoS) demand of the Radio Resource condition adaptation, logic channel of component carrier, perhaps according to the priority orders of default component carrier and the corresponding principle of priority orders of logic channel, the order that these two logic channels according to priority successively decrease is selected corresponding suitable component carrier respectively, and determined mapping relations are: KB1 corresponding to component carrier 1, RB2 corresponding to component carrier 2.
All logic channels successively decrease to calculate respectively on the component carrier of correspondence in proper order according to priority and can satisfy its PBR resource requirement, in the drawings for being designated
Operation.Because the resource U on the component carrier 1 is less than PBR1, so the resource that RB1 is assigned on the component carrier 1 is U, the resource that the remainder of PBR1 is assigned on the component carrier 2 is X-U.The resource that RB2 is assigned on component carrier 2 is Y.
Through above-mentioned steps, the Bj of each logic channel is updated to:
The B1=DATA1-X of RB1;
The B2=DATA2-Y of RB2;
Wherein Bj can be negative value.
All logic channels successively decrease according to priority and calculate the available resources that can be assigned in proper order on the component carriers of correspondence, in the drawings for being designated
Operation.So the available resources that KB1 is assigned on the component carrier 2 are DATA1-X.The available resources that RB2 is assigned on the component carrier 2 are V-Y-(DATA1-U).Because this moment, available resources were not enough to send all data of RB2, i.e. resource situation about having exhausted earlier, the EO of Resources allocation then, certain TTI was scheduled after the remaining data of RB2 was waited for.
According to the aforesaid operations result, the resource that each logic channel is distributed on each component carrier respectively addition respectively (the resource addition that on component carrier 1, is distributed as RB1, the resource addition that RB1 is distributed on component carrier 2, the rest may be inferred), can obtain the size of the MAC SDU that each logic channel generated on corresponding each component carrier; The size of described MAC SDU is the size that described logic channel assigned resource sum on the respective component carrier wave deducts its corresponding MAC head.
In this example, the MAC PDU on component carrier 1 comprises 1 MAC SDU, and by the data on the RB1 are generated, the payload of MAC SDU size deducts its corresponding MAC head length degree for U, and promptly the MAC PDU of Sheng Chenging deducts the length of MAC PDU.The MAC PDU that generates on component carrier 2 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB1, and its payload size deducts corresponding MAC head length degree for DATA1-U; Another one MAC SDU is the data of RB2, the payload size deducts corresponding MAC head length degree for V-(DATA1-U), and this MAC SDU resource requirement adds that by the resource of the satisfied PBR2 that the first round distributes second takes turns the available resources on this component carrier of being distributed.

Be provided with two component carriers that are scheduled as up transmission, be respectively U, V in certain TTI authorized resource.
Principle according to service quality (QoS) demand of the Radio Resource condition adaptation, logic channel of component carrier, perhaps according to the priority orders of default component carrier and the corresponding principle of priority orders of logic channel, the order that these two logic channels according to priority successively decrease is selected corresponding suitable component carrier respectively, and determined mapping relations are: RB1 corresponding to component carrier 1, RB2 corresponding to component carrier 2.
The PBR of high priority logic channel RB1 is Infinity, and first distribution can send RB 1 all data resource requirements; The PBR resource requirement of reallocation low priority logic channel.In the drawings for being designated
Operation.Because the resource U on the component carrier 1 is less than PBR1, so the resource that RB1 is assigned on the component carrier 1 is U, the resource that the remainder of PBR1 is assigned on the component carrier 2 is DATA1-U.The resource that RB2 is assigned on component carrier 2 is Y.
Through above-mentioned steps, the Bj of each logic channel is updated to:
The B1=DATA1-X of RB1;
The B2=DATA2-Y of RB2;
Wherein Bj can be negative value.
Logic channel RB2 calculates the available resources that can be assigned on the component carrier of correspondence, in the drawings for being designated
Operation.So the available resources that RB2 is assigned on the component carrier 2 are V-(DATA1-U).Because this moment, available resources were not enough to send all data of RB2, i.e. resource situation about having exhausted earlier, the EO of Resources allocation then, certain TTI was scheduled after the remaining data of RB2 was waited for.
According to the aforesaid operations result, the resource that each logic channel is distributed on each component carrier respectively addition respectively (the resource addition that on component carrier 1, is distributed as RB1, the resource addition that RB1 is distributed on component carrier 2, the rest may be inferred), can obtain the size of the MAC SDU that each logic channel generated on corresponding each component carrier; The size of described MAC SDU is the size that described logic channel assigned resource sum on the respective component carrier wave deducts its corresponding MAC head.
In this example, the MAC PDU on component carrier 1 comprises 1 MAC SDU, and by the data on the RB1 are generated, the payload of MAC SDU size deducts its corresponding MAC head length degree for U, and promptly the MAC PDU of Sheng Chenging deducts the length of MAC PDU.The MAC PDU that generates on component carrier 2 is by two multiplexing forming of MAC SDU, and one of them MAC SDU is the data of RB1, and its payload size deducts corresponding MAC head length degree for DATA1-U; Another one MAC SDU is the data of RB2, the payload size deducts corresponding MAC head length degree for V-(DATA1-U), and this MAC SDU resource requirement adds that by the resource of the satisfied PBR2 that the first round distributes second takes turns the available resources on this component carrier of being distributed.
The number and the size information thereof of the wireless link control protocol data cell (RLC PDU) that each logic channel of media access control protocol layer (MAC) indication radio link control layer (RLC) can send on each component carrier; Described RLC PDU and above-mentioned MACSDU are corresponding one by one.Rlc layer receives above-mentioned indication information, generates the RLC PDU of corresponding number and size at each logic channel, be submitted to the MAC layer carry out as MAC SDU multiplexing, thereby on corresponding component carrier, generate corresponding M AC PDU.
