Description
Technical field
The present invention relates to field of wireless communication, relate in particular to a kind of data multiplexing method of multi-carrier reinforced uplink access system.
Background technology
The enhanced uplink connecting system is commonly referred to as HSUPA (High Speed Uplink PacketAccess; High speed uplink packet inserts); Be intended to technology through the advanced person and improve the efficient of up link, with effective support web browse, video, multimedia messages and other IP-based business.
Present 3GPP (3rd Generation Partnership Project; Third generation partner program) accomplished TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess; The TD SDMA access) standardization effort of enhanced uplink connecting system is applicable to single carrier TD-SCDMA system.Increased a kind of transmission channel E-DCII (Enhanced Uplink Dedicated Channel in the enhanced uplink connecting system newly; The enhanced uplink dedicated transmission channel); The TTI of E-DCH (Transmission Time Interval, Transmission Time Interval) is 5ms.The grouping that is mapped on the E-DCH transmission channel is called MAC-e PDU (enhancing media access control protocol data unit).
The functional entity that the E-DCH transfer of data relates to is as shown in Figure 1.Wherein 1-1 is transmitting terminal UE (User Equipment; User terminal) protocol architecture figure; RLC (Radio Link Control, Radio Link control) produces RLC PDU (Protocol Data Unit, protocol Data Unit) and sends into MAC (Media Access Control through logic channel after receiving the data on upper strata; The medium access control) layer; MAC-d wherein (specialized media access control) layer is passed to MAC-es/e layer (strengthen Media Access Control and strengthen media access control layer) with data, and the MAC-es/e layer carries out data multiplex, packs the data to MAC-e PDU; And send into physical layer through transmission channel, physical layer is with digital coding modulation back transmission.Receiving terminal comprises Node B (base station) and RNC (Radio Network Controller; Radio network controller); The MAC layer of Node B (like 1-2 among Fig. 1) sends to RNC through frame protocol with data by MAC-e (enhancing media access control layer) after receiving the data that physical layer sends here; MAC-es (enhancing Media Access Control) layer of RNC (like 1-3 among Fig. 1) side reorders to the data on the logic channel, and sends into rlc layer through logic channel after receiving data through the E-DCH Frame Protocol.Before transfer of data begins, be RB (Radio Bearer, the radio bearer) configuration information that UE sets up the E-DCH type by RNC.Detailed workflow is with reference to the 3GPPTS25.321 standard.
In transmitting terminal UE, be responsible for the multiplexing decision-making of logical channel data by the MAC-es/e layer, as shown in Figure 2, with reference to 3GPP TS25.321 standard:
Step 201, after rlc layer receives upper layer data, the current data volume to be sent of notice MAC layer;
Step 202, MAC-es/e layer confirm current data all logic channels to be sent are arranged, and definite logical channel set A, wherein include data highest priority logical channel to be sent and other logic channel that can be multiplexing with this logic channel;
Step 203; The MAC-es/e layer calculates the length k of the MAC-e PDU that maximum can transmit according to the authorization resources of Node B; Confirm a transport block length subclass then, comprise 64 transport block length of system definition in this subclass at most, transport block length maximum in the subclass is smaller or equal to k;
Step 204; The MAC-es/e layer is confirmed the MAC-d PDU number and the length (the just number of RLC PDU and length) of each logic channel successively by the priority of logical channels order; In this process, will check and guarantee MAC-e PDU length all the time smaller or equal to the k in the step 203, and the length of the MAC-e PDU that finally obtains is a value in the transport block length subclass in the step 203.The part of data lack of fill is as filling bit.
In step 204, the MAC-es/e layer among the UE need be optimized data multiplexing, and the factor of consideration comprises but below not limitting: whether need slot milling transmitting scheduling information (MAC layer signaling), make filling bit minimum etc.Through optimized Algorithm, the MAC-es/e layer is confirmed length and the number (being the length of RLC PDU and the number of RLC PDU) of the MAC-d PDU that each logic channel need produce.Thereby following Fig. 3 301 in, rlc layer is that the indication according to the MAC layer produces PDU's.
UE side E-DCH data transmission stream is as shown in Figure 3, wherein, is the hierarchical diagram (with the 1-1 of Fig. 1) of enhanced uplink connecting system UE side rlc layer to physical layer in the 3-1 frame; The 3-2 frame is the DFD of each layer among the corresponding 3-1.UE side E-DCH data transmission stream transmits by following:
301, in a TTI, rlc layer produces one or more RLC PDU, sends to the MAC-d layer through logic channel, and a RLC PDU directly is mapped as a MAC-d PDU;
Among 302, one TTI, be multiplexed into a MAC-es SDU (Service Data Unit), increase header information from a plurality of MAC-d PDU of same logic channel: transmission sequence number (TSN, 3 bits), form MAC-es PDU;
303, the MAC-es PDU that the MAC-es/e layer can be multiplexed among the same MAC-e PDU couples together, and increases header information (several DDI-N to), forms MAC-e PDU.
Wherein, DDI (data description indication) is used to point out the affiliated logic channel of MAC-d PDU, MAC-d stream, MAC-d PDU length information; N is the MAC-d PDU number with identical DDI value.The corresponding a pair of DDI-N of MAC-es PDU.
Article one, use UM (Unacknowledged Mode; Affirmation mode not) logic channel of RLC can be supported 32 kinds of RLC PDU length at most; This lengths sets is by RNC (Radio NetworkController; Radio network controller) be the UE configuration, but in a TTI, a logic channel can only be selected wherein a kind of RLC PDU length.And the logic channel of use AM (Acknowledged Mode, an affirmation mode) RLC is at most only supported a kind of RLC PDU length, and this length value is disposed by RNC.
For the throughput of further raising system, existing single carrier enhanced uplink connecting system will be introduced the multicarrier characteristic, and N carrier system will have N doubly to the throughput of single-carrier system in theory.When introducing the multicarrier characteristic; With the consideration that has multiple framework; Wherein a kind of framework is a multicarrier binding mechanism; Promptly Node B can authorize a plurality of carrier resources for single UE in a TTI, and UE can send the E-DCH data simultaneously on a plurality of carrier waves in a TTI, and the data block that each carrier wave sends is independently.This framework is adopted when HSDPA (high speed downlink packet access) introduces the multicarrier characteristic, and its benefit is to improve the peak rate of single UE.
After introducing multicarrier binding framework, the length of the MAC-e PDU that the MAC-es/e layer among the UE is selected respectively at the authorization resources on each carrier wave according to Node B to transmit on each carrier wave.If one the data to be sent of logic channel can't be multiplexing intact on single carrier resource; Promptly; In the time of need on more than one available carrier wave, sending; The MAC-es/e layer need be taken into account the optimization of data multiplex on a plurality of carrier waves when selecting the RLC PDU length of this logic channel, but is difficult in the reality accomplish.As Fig. 4 and shown in Figure 5 be the example of authorizing 2 carrier waves simultaneously; UE has 2 data on the logic channel to be sent: logic channel 1 and logic channel 2; The priority of logic channel 1 is higher than logic channel 2, and the RLC PDU data of logic channel 1 and logic channel 2 can multiplexingly be transmitted in a MAC-e PDU.As shown in Figure 4, the multiplexing example of the next UE side data of prior art, the 401st, the MAC-es/e layer of the UE side maximum available MAC-e PDU transport block length that the mandate selection on carrier wave 1 obtains according to Node B; The 403rd, the MAC-es/e layer maximum available MAC-ePDU transport block length that the mandate on carrier wave 2 obtains according to Node B.1 high priority data transmission on the logic channel; Have 2 PDU (2 PDU of 405 indications); For making the filling bit in 401 minimum, the MAC-es/e layer is that logic channel 2 has been selected a kind of transport block length (among the figure 406), and the MAC-es/e layer is according to available transport block length subclass; Transport block length on the carrier wave that finally obtains 1 is quantized to length shown in 402, the 408th, filling bit.Residue outgoing data on the logic channel 2 continues to be multiplexed on the carrier wave 2; According to the transport block length 403 of carrier wave 2 and the transport block length 406 of logic channel 2; The MAC-es/e layer confirms on carrier wave 2, can only transmit a RLC PDU (among the figure 407; Its length is identical with 406), and final transport block length is quantized to the length shown in 404 according to system transmissions block length form, 404 deduct remaining bits after 407 can only transmit filling bit (among the figure 409).Fig. 5 is another kind of situation, and the mandate of carrier wave 2 is smaller, and the length 512 of the logic channel of selecting in the carrier wave 12 can't be transmitted in carrier wave 2.
More than 2 example explanations be in multicarrier binding mechanism; When UE sends data simultaneously on a plurality of carrier waves in a TTI; If one the data of logic channel need be mapped to when sending on the more than one carrier wave; Under current mechanism, be difficult to accomplish the optimization of data multiplex on each carrier wave, though can consider transmitting scheduling information in filling bit in the reality, the MAC-es/e layer can't confirm flexibly that data multiplex and the filling bit on each carrier wave is that agreement should improved problem.
Based on following reason, complicated when the data multiplex process of MAC-e PDU will be than single carrier under the multicarrier framework:
1) among TTI, a logic channel can only have a kind of RLC PDU length;
2) among TTI, the authorization resources size of UE on each carrier wave can have nothing in common with each other;
3) among TTI, logic channel multiplexing among the MAC-e PDU on each carrier wave also can have nothing in common with each other.
More than the 2nd) point embodied the flexibility, the 3rd of Node B scheduling) point depends on the type of service of UE.Both of these case all is uncontrollable in the UE side.On business demand; Main flow Packet Service VoIP (Voice Over IP; IP phone) the data packet length range is bigger in, if the 1st) logic channel can only have a kind of RLC PDU length among TTI of some restriction, with segmentation that brings rlc layer or filling; Also for the data multiplex optimization of MAC-es/e layer brings difficulty, reduced efficiency of transmission simultaneously.
