In order to facilitate above-described embodiment is understood, below by taking two logic channels as an example, receiving end and transmitting terminal are by taking UE as an example It is illustrated.

For example, to solve the above-mentioned problems, receive UE need to know some transmission initial data Logic Channel Identifier ID and Its corresponding duplicate packet Logic Channel Identifier is possible to for the two to be tied to the same PDCP receiving entity.In order to realize This point, needs to send UE and broadcasts to the mapping relations between initial data and the corresponding logic channel of replicate data and connect UE is received, so that original original can be differentiated and replicate the relationship of duplicate logic channel by receiving UE, is carried out correct Unpacking processing.Specifically, it is contemplated that following several possible implementations:

1) Fig. 4 is LCID distribution according to an embodiment of the present invention and indicates schematic diagram one, as shown in figure 4, transmitting terminal UE1 Application server (Application Server, referred to as AS) layer receives data packet from high level, and the data packet is to reliability Having higher requirements, (such as the corresponding Packet Error Ratio of the data packet (Packet Error Rate, referred to as PER) is lower than a certain pre-configuration PER thresholding or reliability class be higher than the reliability class thresholding of a certain pre-configuration), UE1 triggering is replicated based on data SL transmission.If not yet creating corresponding PDCP entity/RLC entity/logic channel, holding for data duplication is supported in UE1 creation It carries, including a PDCP entity, two RLC entities, two logic channels.UE is the identical logic letter of two logical channel assignments Road identifies (Logical channel identify, referred to as LCID) 1, but the logic channel for storing duplicate packet increases Adding additional data to replicate instruction information here can abbreviation LCID for distinguishing the logic channel of storage raw data packets 1'.When MAC layer schedule data transmission, believed by member carrier (Component Carrier, referred to as CC) 1 transmission logic The data packet of road LCID 1 passes through the data packet of CC2 transmission logic channel LCID 1 '.The MAC SDU couple assembled by LCID 1 ' On the MAC PDU subheader answered, LCID field is set as 1, and duplication indication field is set as 1, replicates indication field here for referring to Show that the LCID corresponds to the logic channel of duplicate packet.And MAC Service Data Unit (the Service assembled by LCID 1 Data Unit, referred to as SDU) corresponding Medium Access Control (MAC) Protocol Data Unit (Protocol Data Unit, referred to as PDU) subheader On, LCID field is set as 1, and duplication indication field is set as 0, replicates indication field here and indicates that the LCID corresponds to original number According to the logic channel of packet.

After UE1 has sent the MAC PDU of the original and duplicate packet comprising LCID 1 on CC1 and CC2.Around UE1 UE2 receive the MAC PDU sent on CC1 and CC2 successively.Assuming that UE2 receive first MAC PDU, UE2 on CC1 according to The source and target identification field of SL-SCH subheader and the LCID field judgement of MAC PDU subheader need for the data packet to be delivered to The logic channel for being 1 corresponding to the LCID in source and target mark range, if having existed the logic channel, UE2 is by MAC SDU is delivered to corresponding RLC receiving entity, if not yet establishing the logic channel, UE2 establishes the logic channel that LCID is 1 And corresponding RLC entity and PDCP entity, the MAC SDU received is then delivered to corresponding RLC receiving entity.It connects down Carry out UE2 and receives MAC PDU, UE2 on CC2 according to the source and target identification field and MAC PDU subheader of SL-SCH subheader LCID field judge need by the data packet be delivered to corresponding to source and target mark range in LCID be 1 logic letter Road, further, UE2 determine that the MAC SDU corresponds to duplicate packet logic channel according to duplication indication field.If UE2 Not yet replicate data logic channel LCID1 ' of the creation corresponding to LCID1 data, then UE2 establishes the replicate data that LCID is 1 and patrols Channel and corresponding RLC entity are collected, PDCP entity can directly be multiplexed the corresponding PDCP of initial data logic channel that LCID is 1 Then the MAC SDU received is delivered to corresponding RLC receiving entity corresponding with replicate data logic channel by entity.UE2 pairs Should in initial data and replicate data logic channel RLC entity it is independent processing is ranked up etc. to data packet, later Data packet is delivered to the processing that common PDCP entity was ranked up and abandoned repetitive data packet.PDCP layers handle completion Afterwards, which is further delivered to high level and is handled.Generally speaking, due to two RLC receiving entities be associated with it is same PDCP receiving entity, then it is uniformly ranked up and abandons repetitive data packet by PDCP receiving entity, it is received so as to avoid high level To the data packet for largely repeating random ordering.

It should be noted that above scheme there can also be various change, by storage raw data packets rather than can such as replicate The logic channel of data packet carries out data duplication instruction.

Corresponding two logic channels are carried for data duplication, can normally be patrolled for one of logical channel assignment It collects channel logo (such as being distributed within the scope of 00001-01010), and it is visible for second logical channel assignment one only UE1 Any Logic Channel Identifier (such as being selected within the scope of 01011-11011).But when assembling MAC PDU, second logic The LCID of LCID field and first logic channel in the corresponding MAC PDU subheader of channel data is consistent, but MAC The duplication indication field of PDU subheader is set as 1.After reception UE2 receives the MAC PDU, if detecting corresponding MAC PDU The duplication indication field of subheader is set as 1, then UE2 creates replicate data logic channel (if not yet creating corresponding logic letter Road) and corresponding RLC receiving entity, LCID can distribute the only visible any Logic Channel Identifier of UE2 and (such as exist Selected within the scope of 01011-11011), and PDCP entity is then multiplexed the corresponding PDCP receiving entity of LCID1 logic channel.

2) Fig. 5 is LCID distribution according to an embodiment of the present invention and indicates schematic diagram two, as shown in figure 5, transmitting terminal UE1 AS layers receive data packet from high level, and the data packet is higher to reliability requirement, the SL transmission that UE1 triggering is replicated based on data. If not yet creating corresponding PDCP entity/RLC entity/logic channel, the carrying of data duplication is supported in UE1 creation, including One PDCP entity, two RLC entities, two logic channels.UE is that the Logic Channel Identifier of two logical channel assignments is 1 He 2, correspond respectively to the logic channel of storage raw data packets and duplicate packet.When MAC layer schedule data transmission, pass through The data packet of CC1 transmission logic channel LCID 1 passes through the data packet of CC2 transmission logic channel LCID 2.It is assembled by LCID 2 The corresponding MAC PDU subheader of MAC SDU on, LCID field is set as 2, and data duplication opposite end logic channel field is set as 1, Correspond to the Logic Channel Identifier of LCID1.And by the corresponding MAC PDU subheader of the MAC SDU of the data assembling of LCID 1, LCID field is set as 1, and data duplication opposite end logic channel field is set as 2.

After UE1 has sent the MAC PDU comprising LCID 1 and LCID2 logical channel data on CC1 and CC2.Around UE1 UE2 receive the MAC PDU sent on CC1 and CC2 successively.Assuming that UE2 receive first MAC PDU, UE2 on CC1 according to The source and target identification field of SL-SCH subheader and the LCID field judgement of MAC PDU subheader need for the data packet to be delivered to The logic channel for being 1 corresponding to the LCID in source and target mark range, if having existed the logic channel, UE2 is by MAC SDU is delivered to corresponding RLC receiving entity, if not yet establishing the logic channel, UE2 is in source mark and target identification range Inside establish the logic channel and corresponding RLC receiving entity and PDCP receiving entity that LCID is 1, the MAC that then will be received SDU is delivered to corresponding RLC receiving entity.It is noted herein that UE2 also needs before establishing PDCP receiving entity The corresponding logic channel of opposite end logic channel field further is replicated according to the data of MAC PDU subheader, that is, is judged whether The logic channel that LCID is 2 is established within the scope of corresponding source mark and target identification.If having been set up LCID2 logic channel And corresponding RLC receiving entity and PDCP receiving entity, then UE2 can directly be multiplexed the PDCP receiving entity, without being LCID1 Logic channel establish new PDCP receiving entity.Following UE2 receives MAC PDU, UE2 on CC2 according to SL-SCH The source and target identification field of head and the LCID field judgement of MAC PDU subheader need for the data packet to be delivered to corresponding to source The logic channel for being 2 with the LCID within the scope of target identification, further, UE2 replicate opposite end logic channel field according to data Determine that the corresponding duplicate packet logic channel of the MAC SDU is LCID1.If UE2, which is not yet created, corresponds to LCID2 logic letter Road, then UE2 establishes LCID and can directly be multiplexed for 2 replicate data logic channel and corresponding RLC entity, PDCP entity Then it is corresponding to be delivered to LCID2 logic channel by the corresponding PDCP entity of the logic channel of LCID1 by the MAC SDU received RLC receiving entity.RLC entity corresponding to LCID1 and LCID2 logic channel is independent to be ranked up data packet etc. Reason, is delivered to the processing that common PDCP entity was ranked up and abandoned repetitive data packet for data packet later.At PDCP layers After reason is completed, which is further delivered to high level and is handled.Generally speaking, since two RLC receiving entities are associated with It is uniformly ranked up and abandons repetitive data packet to the same PDCP receiving entity, then by PDCP receiving entity, to avoid height Layer, which receives, largely repeats out-of-order data packet.

3) in addition to above-mentioned LCID distribution and PC5MAC PDU subheader indicating mode, it is also contemplated that for carrying raw data packets Logical channel assignment Logic Channel Identifier be n, and carry the duplicate of duplicate packet logic channel be n+k (k > =1) LCID, or using the default or pre-configuration rule of (n+k) mod 10 is carried out to the logic channel of carrying duplicate packet Distribution.It is subsequent send UE1 CC1 and CC2 over-assemble MAC PDU as shown in fig. 6, Fig. 6 is according to an embodiment of the present invention LCID distribution and instruction schematic diagram three.Assuming that it is 1 that n and k points, which are value, then data replicate corresponding two Logic Channel Identifiers point It Wei 1 and 2.It is designated as 1 in the LCID that the corresponding MAC PDU subheader of MAC SDU that CC1 over-assemble LCID is 1 carries, data are multiple System is designated as 1, and is designated as 2 in the LCID that the corresponding MAC PDU subheader of MAC SDU that CC2 over-assemble LCID is 2 carries, number 0 is designated as according to duplication.Assuming that UE2 first receives the data packet sent on CC1, according to data replicate instruction and system default/ Being pre-configured rule judges the corresponding data replication logic channel of LCID1 for LCID2.It is identified when UE2 is subsequently received in same source With within the scope of target identification when the data packet of LCID2, the corresponding PDCP receiving entity of LCID2 logic channel is multiplexed LCID1 logic The corresponding PDCP receiving entity of channel.

It should be noted that in addition to by the way of MAC subheader, it is also contemplated that held by MAC CE or PC5 signaling Above-mentioned instruction information is carried, such as the mapping relations between initial data and replicate data counterlogic channel.The information can only exist It sends, can also be sent on CC2 on CC1, the data replication logic number of channel can also be included in CC1 and CC2 assembling simultaneously According to MAC PDU in send.

It should be noted that present invention could apply to car networkings.Car networking is introduced accordingly below, with logical The development of letter technology and enriching for demand, the application scenarios of wireless communication are also increasingly extensive, wherein comparing typically car networking (Vehicle Networking).So-called car networking is that vehicle can participate in wireless communication, by utilizing advanced nothing Line cellular telecommunication art realizes that vehicle and vehicle, the real-time information interaction between vehicle and trackside infrastructure inform state current each other (position including vehicle, speed, acceleration, driving path) and the road environment information known, collaborative sensing road hazard shape Condition provides a variety of anti-collision warning informations in time, prevents the generation of traffic safety accident.

The mode of car networking communication is specifically divided into three kinds: truck traffic (Vehicle-to-Vehicle Communications, referred to as V2V), vehicle Network Communication (Vehicle-to-Infrastructure Communications, Referred to as V2I), vehicle people communicates (Vehicle-to-Pedestrian, referred to as V2P) three classes, and these three types also may be collectively referred to as Vehicle-to-Everything (referred to as V2X) communication.

Under V2X car networking communication pattern, the transmission of car networking information includes broadcast, multicast and mode of unicast.It is main There are two types of realization technologies: 1) direct discovery/communication (D2D, sidelink, ProSe) based on UE to UE is supported to pass through PC5 interface Carry out the transmission of V2X message；2) it is based on Multicast Broadcast Single Frequency Network (Multicast Broadcast Single Frequency Network, referred to as MBSFN) and single cell point to multiple spot (Single Cell Point to Multipoint, referred to as SC-PTM broadcast mechanism) is supported to carry out the broadcast/multicast transmission of V2X message by Uu mouthfuls or carries out V2X based on Uu mouthfuls of unicasts The unicast transmission of message.It should be noted that the transmission based on PC5 interface can be collectively referred to as D2D, adjacent service (Proximity again Services, referred to as ProSe), equipment lead directly to link (SideLink, referred to as SL).Specific V2X communication can be divided into as follows Three kinds of scenes, Fig. 7 are V2X communication scenes schematic diagrames according to an embodiment of the present invention, as shown in Figure 7:

Scene 1, the scene support SL (Sidelink) the V2X communication based on PC5.UE sends V2X message by PC5 interface To one or more UE.

Scene 2, the scene support that the V2X based on Uu mouthfuls is communicated.UE uplink V2X message is to base station, and base station is by the V2X Message downstream is transferred to one or more UE of regional area.

Scene 3, scene 3 can be divided into scene 3a and scene 3b again, which supports to communicate using the V2V of Uu and PC5 interface. UE by PC5 interface send V2X message to terminal type remote subscriber units (Remote Subscriber Unite, referred to as RSU), terminal type RSU after from PC5 interface to V2X message by the V2X message uplink to wireless access network.Wirelessly The V2X message downstream received from terminal type RSU is transferred to one or more UE of regional area by access net.Alternatively, To wireless access network, wireless access network is received from Uu mouthfuls and is transmitted the V2X message after V2X message UE uplink V2X message The V2X message received from wireless access network is connect by PC5 to one or more terminal type RSU, terminal type RSU Mouth is sent to one or more UE of regional area.

The present invention discusses the communication mechanism that the transmission of car networking message is realized based on PC5 interface.Sidelink is logical at present Letter support two kinds of resources allocation model: 1) resource allocation based on scheduling (Scheduled resource allocation, Referred to as mode 3), UE needs to enter (Radio Resource Control, referred to as RRC) connection status, base station under this mode Proprietary transmission resource is distributed for UE；2) UE primary resource selection (UE autonomous resource selection, also referred to as Mode 4), UE is based on sensing and independently selects resource from resource pool under this mode, this mode can be used for IDLE state or Person's CONNECTED state UE.

With automatic Pilot, the new car networking demand of traveling etc. of forming into columns occurs, and V2V/V2I/V2P business has higher prolong Slow demand is promoted to 10 milliseconds even 3 milliseconds from 100 milliseconds.Meanwhile under the premise of guaranteeing low latency demand, also need to guarantee The high reliability of data transmission.On the other hand, in order to improve data transfer rate, it is desirable that support the concurrently biography on multicarrier Defeated, how UE requests how resource and base station on multicarrier reasonably configure resource, mesh for each carrier wave that terminal uses It is preceding it is not yet found that effect solution.

Such as, UE needs support progress sidelink over a number of carriers and sends and receives data at present.Each car networking number According to a car networking type of service is corresponded to, each car networking type of service corresponds to 2 target identification of layer, and certain vehicle joins Network service type is associated with one or more again can use frequency point.UE can only be closed in transmission vehicle networking data in car networking data It is transmitted on the available frequency point of connection.Based on scheduling resource allocation (Scheduled resource allocation, also referred to as For mode 3), UE can be by sending sidelink buffer status reporting (BootStrap Router, referred to as BSR) Xiang Jizhan Request resource.It include destination index in Sidelink BSR, logic channel group mark and corresponding buffer area are big It is small.However, different data packets is corresponding after introducing data duplication data duplication and data cutting data split How how different available frequency points, UE suitably distribute the resource on each frequency point to base station requests resource and base station, Technology not yet realizes this point at present.

A kind of data pack transmission method for running on above-mentioned mobile terminal is additionally provided in the present embodiment, and Fig. 9 is basis The flow chart of the resource allocation methods of the embodiment of the present invention, as shown in figure 9, the process includes the following steps:

Step S902 receives the resource request auxiliary information that terminal is sent；

Step S904 is terminal distribution data transmission resources according to auxiliary information.

Optionally, auxiliary information includes: datum target mark.

It optionally, include: the buffer status for receiving terminal and sending for terminal distribution data transmission resources according to auxiliary information Report and/or auxiliary information；It is terminal distribution data transmission resources according to buffer area information and/or auxiliary information.

In order to facilitate above-described embodiment is understood, it is exemplified below.

Each car networking data correspond to a kind of car networking type of service, and each car networking type of service corresponds to a layer 2 target identifications.Furthermore each car networking type of service is associated with one or more again can use frequency point.UE is in transmission vehicle networking data When, it can only be transmitted on the available frequency point of car networking data correlation.Mode3UE can be by sending sidelink BSR to base It stands and requests resource.It include destination index, logic channel group mark and corresponding buffer area in Sidelink BSR Size.After introducing data duplication and data split, different data packets has corresponded to different available frequency points. For this scene, The present invention gives UE how how suitably to distribute on each frequency point to base station requests resource and base station Resource optinal plan, it is specific as follows:

1) for given source mark and target identification within the scope of, if data packet correspond to different available frequency point sets (can Mapped with frequency point sets according to type of service and/or determined according to UE carrier wave selection result), then these data packets are delivered to not Same logic channel.That is UE not only considers that source identifies when creating logic channel, unique within the scope of target identification, it is also necessary to examine Consider PPPP information and/or frequency point information and/or reliability (ProSe Per-Packet Reliability, referred to as PPPR) can be used Information.Figure 10 is that logic channel according to an embodiment of the present invention and available frequency point sets schematic diagram are being sent as shown in Figure 10 In UE1, for some target identification destination id1, if there is the corresponding available frequency point sets of data packet are f1, F2 }, { f2 }, { f3 }, { f2, f3 }, { f1 } then needs to create different logic channels for it.Further, if there is data packet Corresponding available frequency point sets are identical, but corresponding PPPP is different, then is also required to create different logic channels for it, such as in mesh LCH1 and LCH2 [] in mark 2 (destination id2) ranges of mark.Further, it is also contemplated that with logic in Fig. 8 Channel group is that unit corresponds to different available frequency point sets, i.e., within the scope of source mark and target identification, corresponding different available frequencies The logic channel of point is associated with different logic channel groups, i.e., in a given logic channel group, it includes logic channel pair The available frequency point answered is identical.

2) for mode 3UE, logic channel group as shown in Figure 10 is created according to the data packet that high level is sent, is patrolled It collects channel and frequency point sets can be used.In order to allow base station that can distribute the information on corresponding carrier resource, sending UE1 can report to base station Resource request auxiliary information.Figure 11 is that SL auxiliary information according to an embodiment of the present invention and BSR report schematic diagram one, such as Figure 11 institute Show, UE reports target identification to base station, corresponds to each target identification, is further contained in each within the scope of target identification Logic Channel Identifier.For each logic channel, corresponding logic channel group mark and/or available frequency point set are further included Conjunction and/or PPPR information.Subsequent UE when reporting SL BSR, BSR may include buffer area index and corresponding buffer size, Wherein buffer area index corresponds to the corresponding index of above-mentioned auxiliary information reported data, and each index uniquely corresponds to a target Mark and Logic Channel Identifier combination.Base station receives above-mentioned resource request auxiliary information and comprising buffer area index and buffer area After the SL BSR of size, the corresponding available frequency point of each logic channel has been known in base station, buffer size and priority (according to The corresponding Logic Channel Identifier of logic channel and the corresponding precedence information of logic channel group), so as to be UE1 scheduling The resource on suitable carrier wave is distributed, the SL for UE1 is transmitted.

3) for mode3UE1, logic channel group as shown in Figure 10, logic are created according to the data packet that high level is sent Channel and frequency point sets can be used.In order to allow base station that can distribute the information on corresponding carrier resource, money can be reported to base station by sending UE1 Request auxiliary information in source.Figure 12 is that SL auxiliary information according to an embodiment of the present invention and BSR report schematic diagram two, such as Figure 12 institute Show, UE reports the target identification information for needing to carry out SL transmission to base station.Further, for each target identification, include Each Logic Channel Identifier within the scope of target identification.For each logic channel, corresponding logic letter is further included Road group identifies and/or can use frequency point sets and/or PPPR information.For subsequent UE when reporting SL BSR, BSR may include target identification rope Draw, Logic Channel Identifier and corresponding buffer size.After base station receives above-mentioned resource request auxiliary information and SL BSR, The corresponding available frequency point of each logic channel has been known in base station, and buffer size and priority are (corresponding according to logic channel Logic Channel Identifier and the corresponding precedence information of logic channel group), so as to be the suitable carrier wave of UE1 dispatching distribution On resource, for UE1 SL transmit.

4) Figure 13 is that SL auxiliary information according to an embodiment of the present invention and BSR report schematic diagram three, for mode3UE1, root Logic channel group as shown in fig. 13 that is created according to the data packet sent of high level, logic channel and can use frequency point sets.With Figure 10 Shown in difference can be compared with the different logic channel of the data creation of frequency point sets, the information on Figure 13 carrier resource, send UE1 can report resource request auxiliary information to base station.As shown in figure 13, UE reports the target mark for needing to carry out SL transmission to base station Know information.Further, for each target identification, report each logic channel group within the scope of target identification to identify with And corresponding available frequency point sets information.For subsequent UE when reporting SL BSR, BSR may include target identification index, logic channel Group mark and corresponding buffer size.After base station receives above-mentioned resource request auxiliary information and SL BSR, base station is known Each logic channel group corresponding available frequency point, buffer size and priority are (corresponding preferential according to logic channel group Grade information), so as to be the resource on the suitable carrier wave of UE1 dispatching distribution, the SL for UE1 is transmitted.

It should be noted that Sidelink communication also supports that base station is that UE configuration half is quiet in addition to above-mentioned dynamic resource scheduling State dispatch resource, R14V2X by UE to base station send semi-continuous scheduling (semi-persistent scheduling, referred to as SPS) assistance messages, wherein comprising periodically, offset, the priority (ProSe of size of data and each adjacent service data packet (Proximity Service) priority per packet, referred to as PPPP) etc. instruction information, carry out assistant base station for UE point With SPS SL resource.In view of multicarrier scene, base station is in addition to carrying out SPS configuration for UE, it is also necessary to it is available to be thought of as UE distribution SPS resource on frequency point, the prior art not yet realize this point.

It for the SPS resource allocation based on mode3, sends UE and needs to report auxiliary information, help base station configuration and swash Suitable SPS process living.UE auxiliary information may include the following contents: estimation packet reaches the period, and estimation packet reaches offset, PPPP value, MAC PDU size etc..In order to carry out the SL transmission based on SPS in multicarrier, the auxiliary information that UE is reported to base station is removed Estimation packet reaches the period, and estimation packet reaches offset, and PPPP value, MAC PDU size etc. can also include available carrier wave set And/or the information such as PPPR.After base station receives above- mentioned information, the SPS resource in available carrier wave can be configured/activated for UE.UE is received After SPS configuration and SPS resource active, SL transmission can be carried out on corresponding carrier wave.

In view of data replicate scene, UE is needed in two different carrier wave transmitting datas, to need in two carrier waves Upper activation SPS SL transmission.In this case, the auxiliary information that UE is reported to base station wraps in addition to estimation and reaches the period, and estimation packet arrives Up to offset, PPPP value, MAC PDU size etc. can also be indicated comprising available carrier wave set and/or PPPR and/or data duplication, Figure 14 is multicarrier SL SPS transmission schematic diagram according to an embodiment of the present invention, as shown in figure 14.After base station receives above- mentioned information, Two carrier waves are selected to distribute/activate SPS resource respectively for UE from available carrier wave set.UE receives SPS configuration and SPS resource After activation, SL transmission can be carried out on corresponding carrier wave.

Further, carrier wave selection is carried out if it is UE, then the data of SPS is replicated, the auxiliary that UE is sent to base station It may include that UE selects two available carrier wave information and data duplication instruction in information.After base station receives above- mentioned information, this two SPS resource is distributed/activated respectively on a carrier wave for UE.After UE receives SPS configuration and SPS resource active, it can be carried accordingly SL transmission is carried out on wave.

The carrier wave selection of UE includes two levels: according to service type service type, PPPP, UE ability, channel is accounted for Available carrier wave is selected with ratio (Channel Busy Ratio, referred to as CBR) etc..Here available carrier wave is implicit refers to that UE can be same The carrier set of Shi Jinhang sensing.For mode4 resource distribution mode, the transmission resource selection of UE is dependent on UE's Sensing result.The variable number that usual UE can carry out perception sensing simultaneously is greater than the load that UE can be sent simultaneously Wave number.Therefore V2X flow (traffic) configuration for carrying out to be limited to according to Rx chain when carrier wave selection in UE corresponds to The candidate frequency point of number, Figure 15 are that carrier wave according to an embodiment of the present invention selects and switches schematic diagram, as shown in figure 15.

For carrier switch, interested available carrier wave information can be sent to base station by the UE of connected state, and base station is corresponding It is that UE configures mode4 on these carrier waves or mode4 and sends resource pool.For mode4 resource distribution, UE starts to carry these Mode4 on wave sends resource pool and carries out sensing and measurement.

In view of the Rx chain of UE is limited, it is also conceivable to following any original when selecting the carrier wave of sensing/ measurement Then: 1) guaranteeing to cover all V2X dynamic flows (traffic flow) as far as possible, that is, contain at least one a certain V2X The available carrier wave of traffic flow.It, can be with preferred priority if 2) not can guarantee each V2X flow traffic of covering The high corresponding available carrier wave of V2X traffic.3) in general Tx UE is also required to carry out sidelink reception simultaneously, therefore UE will also consider that sidelink is received while selecting sensing/ measurement carrier wave, disappear from the sidelink that receive as far as possible more For the angle of breath, UE can the high carrier wave of preferred CBR value.

After Mode 4UE completes sensing/ measurement carrier wave selection, these carrier waves are measured, report CBR to survey to AS layers Amount at the same time, can report sensing to MAC layer as a result, for selecting the load as a result, for the suitable carrier wave of UE selection Resource on wave.For carrier wave and resource selection, following several situations can be divided into:

The n Tx chain (Tx chain per subframe) of the every subcarrier of UE selects n different carrier waves to carry out Sidelink is sent: this mode is equivalent to m (m > n, m≤perception number of carrier wave sensing of UE time-sharing multiplex Carrier no.) carrier wave progress sidelink transmission.Which is most flexible, is suitble to UE to need to send correspondence simultaneously multiple and different Frequency point sets V2X traffic scene can be used.

The n Tx chain of UE is fixed (with second rank) in a long time to select n carrier wave to carry out sidelink transmission: This mode has once selected some carrier wave, it will usually which last longer, the Tx chain of UE can also continue in this carrier wave (carrier) it is sent on.In general, the number of Tx chain and selection carry out carrier of sidelink transmission Number is identical.Unless overload occurs in this carrier, or no longer there is the V2X needed using this carrier Traffic, can just reselect other carrier, need to carry out the switching (switch) of Tx chain at this time.

The carrier wave selection mode become slowly corresponding for the latter leads to selected carrier wave carrier hair if there is CBR variation Changing then will lead to the corresponding available carrier wave carrier of logic channel logical channel and change, need at this time Some Tx chain is triggered from carrier wave carrier f1switch to the carrier f4 newly chosen, for the resource of SPS type Scheduling, it is possible to which SL_RESOURCE_RESELECTION_COUNTER is not yet kept to 0.Tx chain carries out carrier switch at this time The opportunity of (carrier switch), there are several types of possibilities:

Once having selected new carrier, the Tx chain of UE sends out assembled MAC PDU in carrier f1 After having sent, certain time may be needed by beginning to switching switch to carrier f4, switch, later the Tx chain of UE Work is begun on carrier f4.

For the resource selection mode of SPS, if having selected one group of SPS resource, and SL_RESOURCE_ originally Etc. RESELECTION_COUNTER is not yet kept to 0, can continue to use the rule of dynamic dispatching at this time, i.e., all corresponds to carrier For the sidelink process process of f1 by after assembled MAC PDU has been sent, pause uses the carrier wave, corresponding Hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest, HARQ) process can hang up/reset/ Release.

Consideration waits until the SL_RESOURCE_ of all sidelink process corresponding to carrier f1 After RESELECTION_COUNTER becomes 0, then stop using carrier f4.

For the carrier wave selection become fastly, the scheduler of UE needs the MAC PDU to be assembled to each when dispatching resource The resource on which carrier wave, the resource in which subframe can be used according to PPPP and CBR judgement.When UE has selected some carrier wave When resource in a subframe, it is also necessary to further consider whether the subframe corresponds to the Tx chain switch time.What a is selected After resource on carrier wave, when UE continues MAC PDU after assembling, need to continue to carry out carrier wave selection, the carrier wave according to PPPP and CBR It is possible that carrier wave corresponding with previous MAC PDU is identical, it is also possible to different.If it is different, then needing further to consider choosing Select the resource on second carrier wave in which subframe, in addition to considering possible Tx chain switch, if the subframe of selection with First carrier wave has overlapping overlap, it is also necessary to further consider whether to support such bandwidth combination band Combination, and whether it is able to satisfy PSD demand.

Corresponding to this mode, the gravity treatment of carrier wave is each MAC PDU triggering.The mode4 of SPS type is passed Defeated, then after SL_RESOURCE_RESELECTION_COUNTER times before waiting until is transmitted, UE scheduler is rethought Which which transmitted using the resource in subframe of carrier wave.

The basic thought of above-described embodiment is as follows:

1) UE is that the corresponding logic channel of data duplication only distributes a LCID, and one is logic channel 1, separately One is 1 ', UE when assembling the two data packets, is wrapped in the MAC subheader of the MAC SDU of 1 ' corresponding logic channel assembling The LCID contained is 1, but increases data duplication instruction in MAC subheader.After receiving end receives the data packet, according to LCID the and data duplication instruction that MAC subheader includes can pick out the data that the data packet corresponds to LCID1 Packet replication logic channel, to be tied to the PDCP receiving entity corresponding to logic channel 1 for it；

2) UE is when creating logic channel, identical if two V2X data packet correspond to identical target id PPPP, but correspond to different available frequency point sets, then it should create different logic channels.Therefore, different source id, target Id can use frequency point sets, PPPP, corresponding different logic channel.

3) if it is considered that eNB determines carrier wave selection, then 1) for dynamic resource scheduling, which UE reported to base station Destination id, corresponding logic channel, each logic channel corresponding PPPP, LCGID can use frequency point sets, subsequent UE reports LCH index/buffer index/LCGID and buffer size when reporting sidelink BSR；2) SPS is provided Source scheduling, UE need to be used for comprising the corresponding available frequency point sets of every SPS auxiliary information into the auxiliary information that base station reports ENB can use the SPS resource on frequency point for its distribution.

4) carrier wave of rrc layer is selected, causes selected carrier to change if there is CBR variation, then will lead to The corresponding available carrier of logical channel changes, and needs to trigger some Tx chain at this time from carrier F1switch is to the carrier f5 newly chosen, for the scheduling of resource of SPS type, it is possible to SL_RESOURCE_ RESELECTION_COUNTER is not yet kept to 0.At this time Tx chain can until Tx chain in carrier f1 by group After the MAC PDU installed has been sent, start switch to other carrier waves, or wait and all correspond to carrier f1's Sidelink process after assembled MAC PDU has been sent, will start switch to other carrier waves.

Through the above description of the embodiments, those skilled in the art can be understood that according to above-mentioned implementation The method of example can be realized by means of software and necessary general hardware platform, naturally it is also possible to by hardware, but it is very much In the case of the former be more preferably embodiment.Based on this understanding, technical solution of the present invention is substantially in other words to existing The part that technology contributes can be embodied in the form of software products, which is stored in a storage In medium (such as ROM/RAM, magnetic disk, CD), including some instructions are used so that a terminal device (can be mobile phone, calculate Machine, server or network equipment etc.) execute method described in each embodiment of the present invention.
