Specific embodiment

To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall in the protection scope of this application.

Before introducing transfer control method provided by the present application, transmission (PDCP is repeated to PDCP first Duplication it) describes in detail, specifically, 5G NR (next generation Radio, next-generation wireless) system master Support following three classes business: eMBB (enhanced Mobile Broadband, enhanced broadband connections), mMTC (massive MachineType Communications, a large amount of machine type communications), URLLC (Ultra-Reliable And Low LatencyCommunications, highly reliable low time delay communication).

Wherein, for URLLC, since it has relatively high requirement to time delay and reliability, at present 3GPP provide one Kind solution is to introduce PDCP duplication (PDCP repeats to transmit) mechanism, i.e., identical by multiple path transmissions PDCP layers of PDU (Protocol Data Unit, protocol Data Unit) promote transmission reliability by multiplexing gain, and Reduce propagation delay time.

During PDCP repeats a concrete implementation of transmission, in the PDCP layer of transmitting terminal, such as can be by one PDCP PDU is copied into identical two parts and is handed down to two different RLC entities respectively, wherein different RLC entities can be right It answers different cells (cell), and then the transmission of initial data and the biography of replicate data can be carried out by different cells respectively Defeated, if receiving end has successfully received initial data and replicate data, the PDCP layer in receiving end is identical to what is had successfully received Two PDCP PDU are deleted therein a and are only retained a data, that is to say, that the cladding of same part data are made identical Two parts and transmitted by two different links, thus improve data transmission reliability, it is worth noting that, on Give an account of continue be copied into identical two parts and be only exemplary explanation, during concrete implementation, specifically data are replicated more Few part can be selected according to demand.

Specifically, needing to configure PDCP to RB first when repeating the reliability of transmission improve data transfer using PDCP Transfer function, the corresponding PDCP entity of one of RB are repeated, only RB is configured with PDCP and repeats transfer function, can lead to It crosses the corresponding multiple RLC entities of RB respectively to transmit the PDCP PDU of original PDCP PDU and duplication, below with reference to Fig. 1 The realization process for repeating transfer function to RB configuration PDCP is illustrated, Fig. 1 is that the interaction of terminal device and the network equipment is shown It is intended to, as shown in Figure 1:

The network equipment can send wireless heterogeneous networks (Radio Resource Control, RRC) to terminal device and disappear Breath, RRC information may include that the PDCP of RB repeats the configuration information of transfer function, specifically, RRC information can be designated as some configuration The RB that PDCP repeats transfer function establishes the RLC entity for repeating to transmit of at least one additional, so that subsequent It can be transmitted respectively by PDCP PDU of the different RLC entities to original PDCP PDU and duplication, optional real It applies in example, RRC information can also indicate the cell packet identification (cell group ID) and logical channel identifier of RLC entity (Logical Channel ID, LCID)；Alternatively, the RB that RRC information can also repeat transfer function to be respectively configured with PDCP is set Set the initial state (activation or not activating) of repetition transfer function.

Here the configuration information for including in RRC information is simply introduced again, wherein duplication match confidence Breath is included in a big RRC information, specifically, this RRC information may include the configuration information of many RB, also having can Can contain the configuration information of all RB of current terminal device, and the configuration information of each RB contain it is very various Data, and the functional information for being used for duplication is one or two of field in configuration information, representing when field occurs should RB is configured with duplication, does not occur, and represents the RB and does not configure duplication.

In addition, referring to Fig. 1 it is found that RB in the present embodiment can for Data Radio Bearer (Date Radio Bearer, DRB) or Signaling Radio Bearer (Signalling Radio Bearer, SRB), specifically, SRB be only used to transmit RRC information and Non-Access Stratum (Non-Access Stratum, NAS) message, and DRB is for carrying user data, wherein a RB can be right Answer a PDCP entity, wherein the data in either SRB or DRB, PDCP layers all include two types: PDCP Data PDU and PDCP Control PDU, wherein PDU represents a data cell, can be understood as a data packet, and data packet Be continuously enter PDCP layers from upper layer or lower layer, once duplication function activation, will be to all entrance Duplication is carried out to PDCP layers of PDU and sends operation respectively.

Therefore it is based on above-mentioned introduction, it is to be understood that the RB described in hereafter can be DRB, but in the application It is not excluded for a possibility that RB can be SRB, the implementation transmitted according to SRB is similar with DRB, therefore hereinafter carries out using RB It introduces, covers two kinds of possibilities jointly.

After simply describing to RB configuration PDCP repetition transfer function realization mechanism, below with reference to Fig. 2 and Fig. 3 couples Two different application scenarios that PDCP repeats transmission are illustrated, specifically, PDCP repetition transmission is corresponding, there are two types of applied fields Scape is carrier wave polymerization (Carrier Aggregation, CA) and dual link (Dual Connectivity, DC) respectively.

Fig. 2 is that the PDCP under CA scene repeats mode schematic diagram, and Fig. 3 is that the PDCP under DC scene repeats mode Schematic diagram.

Mode is repeated for the PDCP under CA scene, as shown in Figure 1, the corresponding PDCP reality of PDCP layers of a RB Body, for carrying a PDCP PDU, it is assumed that the PDCP of the corresponding RLC entity 1 of current RB and RLC entity 2 repeats transmission function Can be all in state of activation, then RLC entity 1 and RLC entity 2 may serve to transmission data, one of RLC entity corresponding one A logic channel (Logical Channel, LCH) can then be transmitted in rlc layer by multiple logic channels respectively, In the corresponding RLC entity of each LCH, such as Fig. 2.

Mode is repeated for the PDCP under CA scene, the corresponding multiple RLC entities of RB are opposite with a MAC entity It answers, the data from multiple and different RLC entities is respectively mapped to transmit on different carrier waves.

It is worth noting that different RLC entities corresponds to different cells because PDCP repeat transmission purpose be in order to Multiplexing is to promote the reliability that data are transmitted, therefore different RLC entities corresponding communication cell when transmitting data It has to guarantee to be different, referring to Fig. 2, wherein RLC entity 1 can be with respective cell 1, cell 2, and RLC entity 2 can correspond to Cell 3, cell 4 and cell 5.

Mode is repeated for the PDCP under DC scene, as shown in Figure 2, it was determined that the PDCP under DC scene It is similar with the PDCP repetition mode under CA scene to repeat mode, only difference is that, the corresponding multiple RLC of RB Entity is respectively mapped in different MAC entities, can be respectively mapped to the data from multiple and different RLC entities not naturally With being transmitted on carrier wave, remaining implementation is similar, and details are not described herein again.

On the basis of the usage scenario that above-mentioned Fig. 2 and Fig. 3 are introduced, there is also a kind of couple of PDCP to repeat transmission function at present The implementation of the multi-connection (Multi-connectivity) of the enhancing of energy, below with reference to Fig. 4 to the implementation of multi-connection It is illustrated, Fig. 4 is that the PDCP under multi-connection scene repeats mode schematic diagram, as shown in Figure 4:

It, can be in combination with DC scene and CA scene under the premise of by most two network nodes carry out data transmission PDCP repeat to transmit, allow a data by carrying out the transmission more than two parts of duplications more than both links.

Specifically, referring to fig. 4, wherein PDCP1 corresponds to RB1, it can be seen that each RLC entity of RB1 corresponds to the same MAC Entity 1, therefore the corresponding PDCP being disposed under CA scene of RB1 repeats transfer function；And PDCP2 therein corresponds to RB2, it can To see that the RLC7 and RLC8 of RB2 correspond to a MAC entity 1, RLC1~, RLC2~and RLC3~corresponds to a MAC reality Body 2~, RLC2~and RLC3~carrys out word, RB2 is corresponding to be so if being with RLC7 and RLC8, or with RLC1 PDCP repetition transfer function of the configuration under CA scene, but the RLC8 of RB2 and RLC1~correspond to two different MAC realities Body, so if be with RLC8 and RLC1~for (or RLC1~and RLC7 etc.), RB2 is corresponding to be disposed on DC scene Under PDCP repeat transfer function.

It should be noted that corresponding cell is centainly different under different MAC entities, likewise, different MAC is real RLC entity corresponding to body is also centainly different, therefore, RLC1 and RLC shown in Fig. 4~and it is entirely different RLC real The entirely different cell of body and cell group 1 and cell group 1~be also, remaining RLC2 and RLC2~wait and similar are Entirely different, details are not described herein again.

When carrying out data transmission, a data can be by carrying out being more than two parts of duplications more than two logic channels Transmission, it is worth noting that, in conjunction with above-mentioned introduction it is recognised that each RLC entity of PDCP1 corresponds to different cell groups, Each RLC entity of PDCP2 corresponds to different cell groups simultaneously, but corresponding to the RLC entity of the RLC entity of PDCP1 and PDCP2 Cell group in cell can partially overlap or be completely coincident, as long as that is, guarantee for same part data carry out transmission be corresponding Be different cell, referring to Fig. 4, the corresponding cell group of each RLC entity of PDCP1 is all different, and PDCP2's is each The corresponding cell group of RLC entity is also all different, but the RLC of RLC the entity 1 corresponding cell group 1 and PDCP2 of PDCP1 Cell in the corresponding cell group 7 of entity 7 can be partially overlapped or is completely coincident.

The mechanism of action of transmission repeated to PDCP in through the foregoing embodiment and after usage scenario is introduced, is needed Illustrate, Yao Shixian PDCP repeats to transmit, it is also necessary to which the PDCP for controlling RLC entity repeats the state of transfer function, wherein shape State can be activation or un-activation, and when it is activation that the PDCP of RLC entity, which repeats transfer function state, showing can be by working as Preceding RLC entity transmitting data shows to pass through when it is un-activation that the PDCP of RLC entity, which repeats transfer function state, Current RLC entity transmitting data.

Specifically, being primarily present following two implementation to the PDCP controlling mechanism for repeating transmission at present:

1) network dynamic controlling mechanism

The network equipment sends control signaling to terminal device, includes a bitmap (bitmap), bitmap in control signaling In include multiple positions (bit), each bit respectively corresponds a RB for being configured with PDCP function, in a kind of possible realization side In formula, wherein corresponding to some RB bit be designated as 1, then represent and activate the RB, the corresponding position bit is designated as 0, then generation Table deactivates the RB；Alternatively, 0 indicates to deactivate in alternatively possible implementation, 1 indicates to deactivate.

Meanwhile be configured with all RLC entities corresponding to the RB of PDCP function have corresponding respective bit indicate its swash Living or deactivation, in one possible implementation, 1 indicates activation, and 0 indicates to deactivate；Alternatively, can also be using at least One bit indicates the RLC entity for needing to activate, such as includes: 001,010 and 100 in the control signaling issued for RB1, Then indicate that currently needing the RLC entity activated is RLC1, RLC2 and RLC4, remaining various possible implementation can be with root It is selected according to actual demand, such as deactivated RLC can also be needed real using at least one bit instruction in control signaling Body, details are not described herein again for remaining implementation.

Wherein, some is configured with after PDCP repetition transfer function RB activation, and PDCP layers can carry out duplication behaviour to data packet Make, and identical two parts of PDCP PDU are sent respectively to two RLC entities corresponding to this RB, the two RLC entities will The PDCP PDU of original PDCP PDU and duplication can be sent respectively.

In addition, after some RB is deactivated, corresponding to logic channel (Logical Channel, LCH) and carrier wave Between corresponding limitation be just cancelled, PDCP layers of transmitting terminal will not carry out duplication operation to new data packets, and to original RLC Entity sends new data, and without sending new data to additional RLC entity, transmitting terminal PDCP entity is notified that additional RLC is real Body is canceled data cached in additional LCH, it is to be understood that also corresponds to additional RLC entity and is deactivated.

2) autonomous control mechanism of the terminal device based on thresholding

The network equipment is provided to terminal device for controlling activation or deactivated control thresholding (or control condition), Terminal device measures each variable corresponding to control thresholding, if the threshold value of network equipments configuration is satisfied, eventually End equipment voluntarily can carry out activation/deactivation operation to corresponding RLC entity.

Wherein, control thresholding for example may include following several:

A, channel status

B, the hybrid automatic repeat request of MAC layer (Hybrid Automatic Repeat Request, HARQ), or RLC automatic repeat request (AutomaticRepeatreQuest, ARQ) feedback

C, packet loss

D, packet transmission delay

It is illustrated by taking above-mentioned control thresholding B as an example, it is assumed that the packet loss that present terminal equipment detects is greater than default Packet loss can then determine that packet loss event frequently occurs for current RLC logic channel, then show current RLC entity be not suitable for into The PDCP of the current RLC entity state for repeating to transmit then is set as deactivating by the transmission of row data；Again with above-mentioned control door It is illustrated for limit A, it is assumed that current channel status is preset state, then can determine that current RLC logic channel is suitble to The transmission of data is carried out, so that the PDCP of the current RLC entity state for repeating to transmit is set as activating, wherein preset state example It such as can be L1 or L3 filtered RSRP/RSRQ threshold or path loss, it is to be understood that Above-mentioned control thresholding is only exemplary introduction, and not exclusive restriction, and the specific implementation for controlling thresholding can be according to reality Border demand is set, while being controlled thresholding and being can choose one such or any number of combination etc., and the present embodiment is to this It is not construed as limiting.

Introduction based on above two controlling mechanism, it should be noted that network dynamic controlling mechanism is that necessity of UE is special Sign, i.e., it needs not move through what any configuration just can be achieved on, but autonomous control mechanism of the terminal device based on thresholding is The configurable mechanism of supplement, therefore the network equipment can be the configuration of the terminal device selectivity controlling mechanism, while network Equipment can also be by RRC information or other control signalings come so that the controlling mechanism is effectively or invalid.

If some is configured with DRB autonomous control machine based on thresholding that is configured with terminal device that PDCP repeats transfer function System, the then control instruction that the control instruction and terminal device that the network equipment issues independently generate can cover mutually, because eventually The case where control instruction that end equipment independently generates may only take into account itself, but the control instruction that the network equipment issues can The case where capable of having planned as a whole whole network, then the network equipment can wish decision that oneself is issued by control signaling in the regular hour Be inside it is effective, it is not to be covered or should not Land cover quickly, the control instruction meeting that soon overlay network equipment issues Reduce the utilization efficiency of resource and the system performance of totality.

Based on the above issues, this application provides a kind of transfer control method, to improve the utilization efficiency of resource and total The system performance of body describes to transfer control method provided by the present application in detail below with reference to Fig. 5, and Fig. 5 is that the application is real The flow chart one of the transfer control method of example offer is provided, as shown in figure 5, this method comprises:
