Description
Technical field
The present invention relates to the communications field, relate in particular to synchronous implementation method of a kind of transfer of data and device.
Background technology
Fig. 1 shows 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, abbreviate LTE as) the structural framing figure of the Radio interface protocols stack of " universal land radio access web of evolution (the Evolved UniversalTerrestrial Radio Access Network; abbreviate E-UTRAN as) " of system, as shown in Figure 1, RRC (Radio Resource Control, Radio Resource control) handle UE (User Equipment, subscriber equipment) the 3rd layer of information of control plane and between the UTRAN, in addition, MAC (Media Access Control, the medium access control) layer protocol, RLC (Radio Link Control, Radio Link control) layer protocol, PDCP (Packet Data Convergence Protocol, PDCP) constitutes layer 2.
Fig. 2 shows the structural framing figure of uplink layer 2, as shown in Figure 2, the PDCP layer protocol comprises head compression (ROHC), safety (Security), the rlc layer agreement comprises segmentation/Segm.ARQ etc such as automatic repeat requests, there is scheduling/processed (Scheduling/Priority Handling) functional entity at mac-layer protocol, multiplexing (Multiplexing), mix automatic repeat requests (Hybrid ARQ, abbreviate HARQ as), wherein, support dynamic dispatching (Dynamic Scheduling) of scheduling feature entity and semi-persistent scheduling (Semi-persistent Scheduling, or be called semi-persistent scheduling).
When up dynamic dispatching function is meant up processing, E-UTRAN can be by sub-district-Radio Network Temporary Identifier (the Cell RadioNetwork Temporary Identifier on 1/ layer of 2 (L1/L2) control channel of layer, abbreviate C-RNTI as) at each Transmission Time Interval (Transmit Time Interval, abbreviate TTI as) to the UE Resources allocation, when allowing to carry out descending reception, UE is 1/ layer of 2 control channel of supervisory layers always, is the possible resource allocation of up transmission.Wherein, 1/ layer of 2 control channel of layer is meant Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviate PDCCH as), when being used for uplink scheduling, mainly carries this channel uplink authorization (UL Grant), when uplink scheduling, UE is by Physical Uplink Control Channel (Physical Uplink Control Channel, abbreviate PUCCH as) carry dispatch request (SR) or channel quality indication (Channel QualityIndicator, abbreviate CQI as), Physical Uplink Shared Channel (Physical Uplink SharedChannel abbreviates PUSCH as) is used to send upstream data.E-UTRAN mixes affirmation/non-affirmation response message ACK/NACK of HARQ to the data feedback of the up transmission of UE by the automatic repeat requests indicating channel of physical mixed (Physical Hybrid ARQ IndicatorChannel abbreviates PHICH as).
Up semi-persistent scheduling is meant that E-UTRAN can send the predefined ascending resource of distribution for the HARQ first of UE, opportunity (Timing) for example, resource, transformat parameters such as (Transport format), during UE is by the subframe of pre-allocation resource (Subframe), if UE does not find its C-RNTI on the L1/L2 control channel, then UE carries out up transmission at corresponding TTI according to the predefine resource, network based predefined Modulation and Coding Scheme (Modulation Coding Schedule abbreviates MCS as) is decoded to predefined Physical Resource Block (PRB).In addition, during UE was by the subframe of pre-allocation resource, if UE has found its C-RNTI on the L1/L2 control channel, then UE carried out up transmission at corresponding TTI according to the indicated information of this L1/L2 control channel.
In the LTE system, exist because the limited problem of up covering that the ascending power restriction causes is the example explanation with ip voice (Voice over Internet Protocol abbreviates VoIP as) business below at cell edge:
At cell edge, because uplink budget is low, in a TTI, possibly can't finish the transmission of whole VoIP packet, so just need to pass through at wireless chain control layer (Radio Link Control, abbreviate RLC as) the VoIP packet is carried out segmentation, in a plurality of TTI, send these segmentations respectively, by increasing the header overhead of layer 2, the transmission of each segmentation need send uplink authorization (Grant) on PDCCH, can increase the consumption of PDCCH resource like this, and each head passes or re-transmission all need be at the automatic repeat requests indicating channel of physical mixed (Physical Hybrid ARQ Indicator Channel, abbreviate PHICH as) last feedback acknowledgment message/non-acknowledge message (ACK/NACK), can increase wrong probability like this, can address the above problem by carrying out up TTI boundling (TTI Bundling) scheme, wherein, the TTI bunching scheme allows to use one group of continuous transmission block (Transport Block of subframe transmission, abbreviate TB as), retransmit the feedback that once sends before not needing to wait at the HARQ of TTI boundling inside like this, single TTI boundling uses same HARQ process, only needs the single feedback.
E-UTRAN opens the TTI bunching scheme of UE by the RRC signaling, but the TTI bunching scheme needs E-UTRAN and UE to keep synchronously in the parameter configuration of physical layer, in addition, E-UTRAN also may reshuffle the TTI bunching scheme of UE by the RRC signaling, the TTI bunching scheme also should have corresponding stopped process, and these processes also should need E-UTRAN and UE to keep synchronously in the parameter configuration of physical layer.
In the existing TTI bunching scheme, how E-UTRAN and UE keep not providing concrete solution synchronously in the parameter configuration of physical layer, therefore, need a kind of scheme that can address this problem.
