Present patent application file is filing date 2013-09-27, Application No. 201310452179.X, The application for a patent for invention literary composition of invention entitled " uplink scheduling request method, uplink dispatch method and equipment thereof " The divisional application of part.

Technical field

The present invention relates to the communications field, particularly relate to uplink scheduling request method, uplink dispatch method and set Standby.

Background technology

E-UTRAN (evolved Universal Terrestrial Radio Access Network, evolution general Terrestrial Radio Access Network) the network architecture as it is shown in figure 1, E-UTRAN by eNB (evolved NodeB, Enode b, i.e. base station) composition.ENB completes access network function, with UE (User Equipment, Subscriber equipment, i.e. terminal) pass through idle port communication.Not only there is chain of command between UE with eNB to be connected but also exist User face connects.The UE of network is attached to for each, by a MME (Mobile Management Entity, Mobility Management Entity) provide service for it, use S1-MME to connect between MME and eNB Mouth is connected.S1-MME interface provides chain of command service for UE, including mobile management and bearer management Function.S-GW (Serving Gate Way, gateway) is connected with using S1-U interface between eNB, The UE being attached to network for each, has a S-GW to provide service for it.S1-U interface is UE Thering is provided the service of user face, the user face data of UE is carried between S-GW and eNB transmission by S1-U.

Along with data service rate and the continuous of capacity requirement are increased by fast development and the user of intelligent terminal Long, traditional macro base station individual layer overlay network can not meet the business demand of people.Therefore, 3GPP Introduce layering networking mode to solve this problem: by hot spot region, family's indoor environment, office The little overlay environment such as environment lays some lower powered nodes (referred to as home base stations Local eNB or small-cell Small cell, including the form such as Femto, Pico or relaying), it is provided that little scope covers, it is thus achieved that little differentiation The effect split so that operator can provide the user the business of more high data rate, lower cost.

In the case of layering networking, in order to strengthen mobile management or improve peak rate, UE may polymerization The resource of the community of multiple base stations, can also support a kind of network architecture carrying separation further so that A part of radio bearer (Radio Bearer, RB) of UE and RRC (Radio Resource Control, Wireless heterogeneous networks) connect maintain on the community that MeNB (Master eNB, main control base station) manages, Another part radio bearer is on the community that SeNB (Secondary eNB, slave base stations) manages.

Under carrying separation scene, a part of Deta bearer of UE carries out maintaining management on MeNB community, Another part Deta bearer carries out maintenance management on SeNB community, and the chain of command of UE carries by MeNB Cell maintenance manages.

For supporting many base stations particularly to carry the UE of separation, the carrying that UE transmits at different base station is Different.When the business being carried on SeNB when UE side has transmitting uplink data demand, if can not be timely Notifying to SeNB by UE in the transmitting uplink data demand of SeNB, corresponding upstream data will be unable to scheduling, Causing upstream data to send in time, propagation delay time is significantly increased, and reduces system and UE performance.

It is thus desirable to consider how to make network side know, UE has transmitting uplink data demand at SeNB, thus Scheduling UE carries out transmitting uplink data in SeNB community further.

Detailed description of the invention

The embodiment of the present invention is applicable to the polymerization of many base stations, particularly carries the scene of separation.

Fig. 2 shows a kind of typical layered network architecture.As in figure 2 it is shown, macro base station (is denoted as Macro ENB) providing basis to cover, lower powered local node (being labeled as Small cell in figure) provides focus to cover , there are data between local node and Macro eNB and/or signaling interface (can be wired or wireless in lid Interface), UE can be operated under Macro eNB or local node.The community controlled due to local node is covered Lid scope is little, and the UE of service is few, so the UE being connected to local node tends to obtain preferably service Quality.Therefore, the covering model of the community corresponding to local node is entered as the UE being connected to Macro eNB When enclosing, local node can be transferred to obtain the service that local node provides；When UE is away from local node During corresponding cell coverage area, need to transfer to the community that Macro eNB controls, to keep wireless company Connect.

The network architecture shown in Fig. 2 can support that carrying separates.In Macro eNB community under carrying separation scene With Small cell community overlapping covered in, support carrying separate UE may be simultaneously operated in Under Macro eNB and Small Cell, use the resource of multiple base station.

It has been generally acknowledged that: under the scene of the polymerization of many base stations (including the base station polymerization that carrying separates), at UE In multiple base stations of polymerization, to provide the base station Macro eNB of grand covering as main control base station Master eNB (or claim MeNB), to provide Small Cell base station that focus covers as Secondary eNB (or title SeNB).Below to provide grand covering and to maintain the base station being connected with UE RRC as MeNB, UE is polymerized Other base stations be explanation as a example by SeNB.

Particularly, when supporting CA (Carrier Aggregation, carrier aggregation) under UE is at SeNB, UE can exist under SeNB a community similar with the main plot MeNB PCell of main control base station (with Lower abbreviation SeNB PCell), this community possesses the function of similar MeNB PCell, supports data transmission, joins It is equipped with PUCCH etc., but the community that the RRC link that cannot function as per UE maintains uses.

The present embodiments relate to random access procedure, understand the embodiment of the present invention in order to clearer, below First the random access procedure provided prior art is simply introduced.

Random access procedure (Random Access Procedure, RA procedure) is UE and network side That sets up Radio Link must be through process.Only after Stochastic accessing completes, be only possible between eNB and UE into The data transmission and reception that row is regular.UE can realize two basic functions by Stochastic accessing: (1) takes Must and eNB between uplink synchronous；(2) application uplink transmission resource.Random access procedure be applied to Lower 6 kinds of scenes: (1) is initially accessed community from RRC_IDLE (RRC is idle) state, i.e. RRC is even Connect foundation；(2) recover after Radio Link Failure, i.e. RRC connection reconstruction；(3) in handoff procedure with mesh Mark cell synchronous；(4) downlink data arrives and UE eats dishes without rice or wine to be in uplink loss state；(5) upstream data Arrive and UE eat dishes without rice or wine to be in uplink loss state, though or non-step-out however it is necessary that by Stochastic accessing application Uplink transmission resource；(6) auxiliary positioning, network utilisation Stochastic accessing obtains Timing Advance (Timing Advance, TA).

In the random access procedure, UE is at PRACH (Physical Random Access Channel, thing Reason RACH) upper send Preamble (leading) code to eNB, Preamble based on UE selection Random access procedure, whether it may happen that collision, can be divided into competition Stochastic accessing (Contention by code Based Random Access, CBRA) and non-competing Stochastic accessing (Contention-Free Random Access, CFRA) two types.For RRC connection establishment, RRC connection reconstruction, UL (Uplink, Up) data arrival scene, Stochastic accessing is independently triggered by UE, and eNB does not has any prior information, because of This Stochastic accessing that is at war with；For handoff scenario, DL (Downlink, descending) data arrive scene, UE initiates non-competing Stochastic accessing according to eNB instruction.

Fig. 3 A shows competition random access procedure, and this flow process comprises the steps that

(1) Msg1: send Stochastic accessing Preamble

This message is UL message.ENB is responsible for preamble code and for transmitting Preamble code PRACH channel resource configures, and will configuration (include ra-PreambleIndex, Prach-ConfigIndex, PRACH Mask Index etc.) result notifies to UE.

Two Preamble code character: A can be further divided into for competing the Preamble set of Stochastic accessing Group and B group.After have selected Preamble code character, UE is from all Preamble codes that this code character is corresponding Select a Preamble code uniformly at random, and from the beginning of first subframe comprising PRACH channel Continuous three subframes in select a PRACH channel uniformly at random, select PRACH channel The upper Preamble code sending selection.

(2) Msg2: accidental access response (RAR)

This message is DL message.This message is the eNB response to UE after receiving Msg1, with Machine accesses response message and sends in accidental access response window.UE CSS on PCell (main plot) Detect on (public search space) RA-RNTI (RA-Radio Network Temporary Identity, with Machine access Radio Network Temporary Identifier) scramble PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) detect RAR message.

(3) Msg3: scheduled transmission

This message is UL message.After UE is properly received Msg2, pass in its uplink transmission resource distributed Defeated Msg3.

(4) Msg4: contention resolved

This message is DL message, for solving potential competition, has determined this random access procedure Concrete UE.UE starts contention resolved timer, and the weight when retransmitting Msg3 every time when sending Msg3 Open this timer.Msg4 content is corresponding with Msg3 content.

Fig. 3 B shows the flow process of non-competing random access procedure, and this flow process comprises the steps that

(1) Msg0: Stochastic accessing indicates

Msg0 message content includes that UE initiates PRACH resource and the Preamble that non-competing RA uses Resource.

(2) Msg1: send Preamble code

The Preamble code sent has been distributed by eNB and has indicated, and therefore UE need not select Preamble Code character and Preamble code.If eNB does not indicate the PRACH channel set allowing to use, then UE A PRACH channel is selected uniformly at random in first subframe comprising PRACH channel；Otherwise, UE selects Article 1 PRACH channel in allowing the PRACH channel set used.UE is in choosing afterwards The Preamble code specified is sent on the PRACH channel selected.

(3) Msg2: accidental access response (RAR)

Transmission and the reception of RAR message are essentially identical with the process in competition random access procedure.Difference It is:

A) there is not competition in non-competing Stochastic accessing, is therefore not related to the transmission of Msg3, rings at Stochastic accessing Answer and message need not comprise Msg3 transfer resource distribution information；

When b) needing again to send Preamble code after receiving random access response message failure, UE is not required to To wait for a period of time based on keeping out of the way instruction, but can directly start PRACH channel determination and The transmission of Preamble code；

If c) UE judges that accidental access response message receives successfully, then it is assumed that whole non-competing Stochastic accessing Process successfully terminates.

The embodiment of the present invention particularly carries the scene of separation for the polymerization of many base stations, it is proposed that in following two Row scheduling scheme:

Direct interaction between scheme one: UE and SeNB, completes transmitting uplink data request and up tune Spend journey.

Interacted by MeNB between scheme two: UE and SeNB, complete transmitting uplink data request And upstream scheduling process.

Below in conjunction with the accompanying drawings, respectively above two uplink scheduling scheme is illustrated.

See Fig. 4, for the schematic flow sheet of the such scheme one that the embodiment of the present invention provides.As it can be seen, This flow process comprises the steps that

Step 401: when UE has transmitting uplink data demand on SeNB, UE sends to this SeNB D-SR (Dedicated Scheduling Request, specific schedule is asked) message or RA-SR (Random Access Scheduling Request, random schedule is asked) message.When being embodied as, when network is UE During the D-SR being configured with on SeNB, this private resource that UE can use network side to be this UE distribution, D-SR is sent to SeNB.When D-SR or the D-SR failure that network is not arranged on SeNB for UE Time (as D-SR transmission exceedes maximum transmission times), UE can be by initiating non-competing Stochastic accessing mistake Journey, asks ascending resource to SeNB.

After step 402:SeNB receives D-SR or RA-SR that UE sends, according to this D-SR for being somebody's turn to do UE carries out described transmitting uplink data distribution uplink transmission resource；Or initiate non-according to RA-SR to this UE Competition random access procedure, or carry out described transmitting uplink data distribution uplink transmission resource for this UE.

When being embodied as, after SeNB receives the RA-SR that UE sends, can determine whether this UE's Uplink sync status, if this UE is in uplink loss state, then determines to this UE initiation non-competing at random Access procedure, if this UE is in uplink sync status, then determines to initiate non-competing RA process to this UE Or distribute uplink transmission resource for this UE.

In a kind of preferred embodiment of flow process shown in Fig. 4, SeNB can be separated to this in the carrying of this UE When SeNB is upper, configuring dedicated preamble for this UE, this dedicated preamble is exclusively used in this UE at SeNB The non-competing random access procedure of upper initiation uses.In step 401, UE can be on the community of this SeNB Send this dedicated preamble, thus carry out uplink synchronous to this SeNB request or request carries out uplink scheduling. In step 402, SeNB can be in the following ways to UE transmission accidental access response message:

Mode one: SeNB, on the community of slave base stations sending this dedicated preamble, uses C-RNTI (Cell-Radio Network Temporary Identity, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) scrambles PDCCH sends accidental access response message to this UE, carries this SeNB in this accidental access response message The uplink transmission resource distributed for this UE.Accordingly, UE is sending the SeNB of this dedicated preamble On community, (this C-RNTI is that SeNB is from the community sending this dedicated preamble to detection use C-RNTI On detect, this C-RNTI is unique in described slave base stations identifies this UE) PDCCH that scrambles, Obtain accidental access response message according to the PDCCH detected, obtain according to this accidental access response message This SeNB is the uplink transmission resource that this UE carries out described transmitting uplink data distribution.

Mode two: support that the CSS (common search region) on SeNB community scans at this UE In the case of, SeNB can use RA-RNTI on the community of slave base stations sending this dedicated preamble (Random Access-Radio Network Temporary Identity, random access radio network is marked temporarily Knowing) PDCCH that scrambles sends accidental access response message to this UE, in this accidental access response message Carry the uplink transmission resource that this SeNB is this UE distribution.Optionally, described accidental access response message In the TC-RNTI information carried be this UE C-RNTI value on the community of this SeNB, should C-RNTI is unique on the community of this SeNB identifies this UE.

Accordingly, UE detection on the CSS of SeNB community sending this dedicated preamble uses The PDCCH of RA-RNTI scrambling, obtains accidental access response message, root according to the PDCCH detected Obtaining this SeNB according to this accidental access response message is that this UE carries out the upper of described transmitting uplink data distribution Row transfer resource.Wherein, described SeNB community can be slave base stations little sending dedicated preamble District, it is also possible to for the main plot SeNB Pcell of slave base stations.For distinguishing UE, if sending this dedicated preamble SeNB community be SeNB Pcell, then can use in the RA-RNTI for scramble PDCCH and carry Send the mode of the information of the community of this dedicated preamble, or use the difference that can use genus base station little The mode that the non-competing random access lead code resource staggered competition random access lead code resource in district overlaps, or Person uses the TC-RNTI information carried in described accidental access response message to be little at this SeNB of this UE C-RNTI value (this C-RNTI is unique on the community of this SeNB identifies this UE) in district.

It is (main little at Pcell that accidental access response message is sent to MeNB, MeNB by mode three: SeNB District) above use the PDCCH of RA-RNTI scrambling to send this accidental access response message to this UE.Described The cell information carried in RA-RNTI is the information of the community sending described special random access preamble code, or The value that TC-RNTI information is C-RNTI carried in accidental access response message described in person, this C-RNTI On this SeNB, unique this UE of mark, by the same configuration identifier of slave base stations and main control base station or main The competition Stochastic accessing preamble resource of control base station and slave base stations overlaps and non-competing Stochastic accessing Preamble resource staggers.

Accordingly, UE detects the PDCCH using RA-RNTI scrambling on the CSS of MeNB Pcell, Accidental access response message is obtained, if that carries in described RA-RNTI is little according to the PDCCH detected District's information is the information of the community sending described special random access preamble code, or described accidental access response (this C-RNTI is unique on this SeNB for the value that TC-RNTI information is C-RNTI carried in message Identify this UE), or main control base station and slave base stations competition Stochastic accessing preamble resource overlap and non- Competition Stochastic accessing preamble resource staggers, then this UE obtains according to this accidental access response message and is somebody's turn to do SeNB is the uplink transmission resource that this UE carries out described transmitting uplink data distribution.

In a kind of preferred embodiment of flow process shown in Fig. 4, in step 401, UE sends D-SR to SeNB Or RA-SR.In step 402, SeNB initiates non-competing random access procedure to this UE.This is non-competing Strive random access procedure and comprise the steps that SeNB is configured to send the resource of random access lead code to UE, And receive the preamble that this UE sends on the community of this SeNB according to this resource, and trigger SeNB Send accidental access response message.SeNB send accidental access response message process, with aforesaid way one, Mode two or mode three send the process of accidental access response message and are similar to, and are not described in detail in this, except for the difference that, Involved preamble is the preamble received from UE in step 402.

By flow process shown in Fig. 4 it can be seen that many base stations polymerization particularly carry separation scene under, UE Transmitting uplink data demand is directly notified SeNB community, so that SeNB community is according to the upper line number of UE According to transmission demand, dispatch this UE and carry out uplink on this SeNB community, solve under this scene such as What makes network know UE UL data transfer demands and UL resource request, asking of scheduling UL data transmission Topic, it is ensured that system and the performance of user.

See Fig. 5, for the schematic flow sheet of the such scheme two that the embodiment of the present invention provides.As it can be seen, This flow process comprises the steps that

When step 501:UE has transmitting uplink data demand in slave base stations, (ratio enters if desired for SeNB Row transmitting uplink data), indicate this UE to have transmitting uplink data demand on this SeNB to MeNB. When being embodied as, UE can send transmitting uplink data demand instruction information to MeNB, and this upstream data passes Defeated demand instruction information is used for indicating this UE to need to SeNB and carries out transmitting uplink data and ask up biography Defeated resource.

Further, this UE can use L1 signaling or RRC signaling or BSR (Buffer State Report, Buffer Status Report) MAC CE (medium education control unit) or the new MAC CE defined, This transmitting uplink data demand instruction information is sent to MeNB.Above-mentioned transmitting uplink data demand instruction information In indicate UE and asked to carry out the community of the SeNB of transmitting uplink data (that is, this SeNB community is The community of this UE request uplink transmission resource).

Further, this L1 signaling can be special scheduling request information, and the request of described specific schedule disappears The resource of breath is, and to be that this UE is preallocated MeNB on be exclusively used in described terminal and transmit subordinate in main control base station The resource of the transmitting uplink data demand instruction information of base station.Accordingly, MeNB receive this specific schedule please The community or the notice SeNB UE that forward it to this SeNB shown in request message indication after seeking message exist There is transmitting uplink data demand the community of this SeNB shown in request message indication.

This request or notice (or transmitting uplink data demand instruction information) are forwarded by step 502:MeNB To this SeNB.When being embodied as, MeNB can be according to indicated in transmitting uplink data demand instruction information The community (i.e. UE is asked to carry out the community of the SeNB of transmitting uplink data) of the SeNB gone out, please by this Ask the community being transmitted to correspondence.Or, MeNB can be according to indication in transmitting uplink data demand instruction information The community (i.e. UE is asked to carry out the community of the SeNB of transmitting uplink data) of the SeNB illustrated, notice SeNB UE has transmitting uplink data demand in the community of the SeNB shown in this request message indication.

Step 503:SeNB, according to this instruction, initiates non-competing random access procedure or for being somebody's turn to do to this UE UE carries out described transmitting uplink data distribution uplink transmission resource.

In step 503, SeNB can first judge this UE asked to carry out transmitting uplink data with this UE Uplink sync status between SeNB community, if desynchronizing state, then SeNB initiates non-competing to this UE Strive random access procedure；If this UE is in uplink sync status, then determine to initiate non-competing RA to this UE Process or for this UE carry out described transmitting uplink data distribution uplink transmission resource.Wherein, SeNB is to this The non-competing random access procedure that UE initiates, can use in Fig. 4 described by step 402 non-competing at random Access procedure.

By flow process shown in Fig. 5 it can be seen that many base stations polymerization particularly carry separation scene under, UE Transmitting uplink data demand is notified to SeNB community by MeNB, so that SeNB community is according to UE Transmitting uplink data demand, dispatch this UE and carry out uplink on this SeNB community, solve this How to make network know UE UL data transfer demands and UL resource request under scene, dispatch UL data The problem of transmission, it is ensured that system and the performance of user.

In order to clearer, the embodiment of the present invention is illustrated, below by a pair such scheme of embodiment one It is described in detail, by embodiment two, embodiment three and embodiment four, such scheme two is retouched in detail State.

Embodiment one

In the present embodiment, when according to situations such as loads, MeNB judges that needs will support the UE's of carrying separation When part carrying is transferred to transmit on SeNB, MeNB sends carrying separation to SeNB and UE respectively please Seek message.After SeNB receives MeNB carrying separation request message, distribute corresponding Radio Resource for UE, This resource includes 1 dedicated preamble (dedicated preamble) that SeNB is UE configuration, uses On SeNB, initiate non-competing random access procedure in follow-up UE to use.The configuration of this dedicated preamble can To be notified to UE by MeNB in carrying separation process, it is also possible under carrying released state, then pass through MeNB or SeNB notifies to UE.This dedicated preamble can be that network allocation is specific to this SeNB Community, it is also possible to be allocated to all communities of this SeNB, i.e. this dedicated preamble and be applicable to this All communities on SeNB.

As shown in Figure 6, in step 601, if UE has transmitting uplink data demand and needs on SeNB Request uplink transmission resource, such as logic channel group in logic channel RLC (Radio Link Control, Wireless spread-spectrum technology) (Packe tData Convergence Protocol, grouped data is converged for entity or PDCP Poly-agreement) entity exists upstream data to be sent, and be between UE and the community of this SeNB The D-SR of uplink loss state or corresponding SeNB does not configures or D-SR configuration failure, then in step In 602, UE uses the dedicated preamble of network side configuration, is needing to carry out the SeNB of transmitting uplink data Select PRACH resource to send dedicated preamble on community, i.e. use this dedicated preamble to initiate this The non-competing random access procedure of SeNB.In step 603～604, as SeNB, to receive this special After preamble, the uplink sync status with this UE kept by detection SeNB, however, it is determined that this UE It is currently at uplink loss state, then completes or initiate non-competing random access procedure；If it is determined that this UE works as Before be in uplink sync status, then for this UE distribute uplink transmission resource.Or, when SeNB receives After this dedicated preamble, it is done directly or initiates non-competing random access procedure.Described complete non-competing with Machine access procedure refers to now send RAR message；The non-competing random access procedure of described initiation refers to: SeNB Send the resource (Msg0) of preamble to UE configuration, make UE send preamble (Msg1), SeNB Return RAR message (Msg2), i.e. trigger UE and initiate non-competing random access procedure.

The RAR message that SeNB generates can be transmitted directly to UE, it is also possible to by MeNB by this RAR Message is transmitted to UE (illustrate only SeNB in Fig. 6 and RAR message is transmitted directly to the situation of UE).

Initiate, as a example by non-competing random access procedure, to describe step 604 and follow-up initiation thereof by SeNB below Non-competing Stochastic accessing realize process.

PDCCH instruction (PDCCH order) that Msg0:SeNB is scrambled by C-RNTI is that UE divides Join preamble resource and/or PRACH resource (step 604).

Preamble resource that Msg1:UE configures according to SeNB and/or PRACH resource, at SeNB Selected preamble code is sent by selected PRACH resource on community.

The transmission of Msg2 can use the one in following three kinds of modes:

After mode A:SeNB receives preamble (Msg0), the PDCCH scrambled by C-RNTI Scheduling RAR message.UE detects, according to the RAR detected on the community sending this preamble Whether message carries this preamble code mark that UE sends, it is determined that non-competing Stochastic accessing is the most successful, And in the case of non-competing Stochastic accessing is successful, obtain TAC MAC CE (Timing Advance Command MAC CE, timing advance order medium education control unit) and UL-grant.TAC Can also detect from the information of C-RNTI scheduling and obtain.Hereafter, UE can according to this TAC and UL-grant, Corresponding uplink transmission resource transmits upstream data to SeNB.Accordingly, UE can send After 2ms after preamble, open RAR window, check possible RAR message.

Mode B: in the case of UE supports to carry out CSS detection on SeNB community, SeNB receives After this preamble, the PDCCH scrambled by RA-RNTI dispatches RAR message.UE is sending Detect on the community of this preamble, according to whether the RAR message detected carries UE send Preamble code mark, it is determined that non-competing Stochastic accessing whether success, and in the success of non-competing Stochastic accessing In the case of obtain TAC and UL-grant.Hereafter, UE can be according to this TAC and UL-grant, right Upstream data is transmitted to SeNB in the uplink transmission resource answered.Wherein, described SeNB community can be to send out Send the community of the slave base stations of dedicated preamble, it is also possible to for the main plot SeNB Pcell of slave base stations.

After mode C:SeNB receives preamble, after generating corresponding RAR head, RAR message, This RAR message is sent to MeNB.MeNB is scrambled by RA-RNTI on MeNB PCell PDCCH dispatches the SeNB RAR message of this UE.UE carries out detecting (RAR on MeNB PCell Window extends, and minimum length is 2+backhaul time delay, and maximum length is 10ms+backhaul time delay), Judge that non-competing Stochastic accessing is the most successful, and in the case of non-competing Stochastic accessing is successful, obtains TAC And UL-grant.Hereafter, UE can be according to this TAC and UL-grant, in corresponding uplink transmission resource Upstream data is transmitted to SeNB.

In aforesaid way B or mode C, UE can use the mode similar with CA (carrier aggregation), Between difference different base station, Stochastic accessing between different districts, adoptable mode includes one below: RA-RNTI carries cell information (identified by this distinguishing cell+preamble, also just distinguish Or eNB realizes staggering non-competing random access resource (as each eNB uses different non-competing UE), Strive preamble resource and identical competition preamble resource, as the different districts under each eNB uses Different non-competing preamble resource), or RAR message uses under SeNB with this UE C-RNTI replaces value (the polymerization base station United Dispatching distribution in original TC-RNTI territory in RAR Identical C-RNTI is used on C-RNTI, and the community be polymerized under same base station of configuration UE) etc..

Additionally, if SeNB supports the many TA of carrier aggregation (CA multi-TA) scene, then SeNB is permissible Sending RAR message on PCell, accordingly, UE can also receive this RAR on SeNB PCell Message.Under this scene, UE needs to increase cell ID when sending preamble, and SeNB scheduling RAR disappears It is also required to during breath embody respective cell identification information.Such as, the RA-RNTI of scrambling PDCCH takes Band cell information, eNB realization is staggered, and (as different in each eNB employing is non-for non-competing random access resource Competition preamble resource but use the competition preamble resource overlapped), RAR message carries C-RNTI Deng.

In flow process shown in Fig. 6, (i.e. send if completing non-competing random access procedure in step 604 RAR), then it implements and the transmission of Msg2 in aforesaid way A, mode B or mode C and process Process is similar to, and in this case involved preamble is the special of UE transmission in step 602 preamble。

Embodiment two

In the present embodiment, support that the UE that carrying separates is operated under MeNB and SeNB simultaneously, and respectively Carry out data transmission with MeNB and SeNB and process.

When UE has uplink demand at SeNB, UE is by the way of reporting instruction, on SeNB Row data transfer demands indicates, and notice MeNB UE has transmitting uplink data demand at SeNB；MeNB Report instruction information according to by this, UE demand is notified SeNB, SeNB perform CFRA or distribution UL resource.The instruction information reported, can be BSR MAC CE, it is also possible to introduce new MAC CE.

As it is shown in fig. 7, in step 701, if UE has transmitting uplink data demand, and UE at SeNB Do not configure or D-SR with the D-SR being in uplink loss state or corresponding SeNB between SeNB community Configuration failure, and still in uplink sync status between UE and MeNB community, the most in a step 702, UE sends should BSR (Buffer State Report, the buffer status report of SeNB to MeNB community Accuse).The BSR that UE sends includes cell ID or Logic Channel Identifier, can be by extension BSR MAC CE form or introduce new LCID (logic channel group mark) mode and indicate this BSR information Corresponding target SeNB community (i.e. needing to carry out the SeNB community of transmitting uplink data).Wherein, use Extension BSR MAC CE mode is for carrying target SeNB in display indicating mode, i.e. this BSR MAC CE Cell ID；The LCID mode using new definition is implicit, i.e. MeNB is by this LCID Can determine that target SeNB of correspondence.

In step 703, after MeNB receives the BSR that UE sends, utilize the community and the base station that preserve it Between corresponding relation or logic channel with base station between corresponding relation (support each self-insurance in base station that separates of carrying Deposit the corresponding relation between community or logic channel and the base station of corresponding UE), it is judged that this BSR is for this Base station (MeNB), or for SeNB's.If MeNB judges that this BSR is destined to SeNB , the most in step 704, the information such as this BSR, UE mark are given this SeNB by MeNB alternately.? In step 705～706, SeNB is according to the notice of MeNB, and up with UE that SeNB keeps Synchronous regime (such as SeNB cell TAT), determines that this UE is current and the synchronous regime of SeNB community, if Determine that this UE is currently at uplink loss state, then initiate non-competing random access procedure；If it is determined that this UE It is currently at uplink sync status, then dispatches this UE uplink, distribute uplink transmission resource for this UE, Or initiate non-competing random access procedure.In the non-competing random access procedure initiated, SeNB passes through The PDCCH order of C-RNTI scrambling is UE distribution preamble resource and/or PRACH resource.UE Preamble resource according to SeNB configuration and/or PRACH resource, on SeNB community, use is selected PRACH resource sends selected preamble code, and receives the RAR message of correspondence.

RAR message can be transmitted directly to UE, it is also possible to this RAR message is transmitted to by MeNB UE (illustrate only SeNB and RAR message be transmitted directly to the situation of UE) in Fig. 7.Particularly, when During non-competing random access resource deficiency, may indicate that UE initiates competition random access procedure.

In above-mentioned flow process, the non-competing random access procedure that SeNB initiates, send out with SeNB in embodiment one The non-competing random access procedure risen is similar to, and is not described in detail in this.

In the specific implementation, in the step 702 of above-mentioned flow process, UE opens RAR window after sending BSR Mouthful.UE can (i.e. SeNB community corresponding for BSR) detection on the SeNB community that BSR sends RAR message, it is also possible to detect the RAR message of SeNB on MeNB PCell.

Embodiment three

In the present embodiment, support that the UE that carrying separates is operated under MeNB and SeNB simultaneously, and respectively Carry out data transmission with MeNB and SeNB and process.Support that the base station that carrying separates each preserves correspondence Corresponding relation between community or logic channel and the base station of UE.

As shown in Figure 8, in step 801, if UE has a uplink demand at SeNB, and UE with It is in the D-SR of uplink loss state or corresponding SeNB between SeNB community not configure or D-SR joins Put unsuccessfully, and still in uplink sync status between UE and MeNB community, the most in step 802, UE The UE data transfer demands at SeNB is sent (as transmitting uplink data demand indicates by MeNB community Information).This transmitting uplink data demand instruction information can be the RRC signaling of a new definition.This instruction Information can be carried cell ID simultaneously or logic channel (group) identifies, report reason (such as SeNB UL Step-out and upstream data reach, ask SeNB UL resource etc.) etc. information.

In step 803, after MeNB receives this instruction information that UE sends, if it is determined that this instruction information For SeNB, the most in step 804, this instruction information is given corresponding SeNB by MeNB alternately. In step 805～806, SeNB is according to the notice of MeNB, and upper with UE that SeNB keeps Row synchronous regime (such as SeNB cell TAT), determines that this UE is current and the synchronous regime of SeNB community, If it is determined that this UE is currently at uplink loss state, then initiate non-competing random access procedure；If it is determined that should UE is currently at uplink sync status, then dispatch this UE uplink, for this UE distribution uplink money Source or initiate non-competing random access procedure.In the non-competing random access procedure initiated, SeNB passes through The PDCCH order of C-RNTI scrambling is UE distribution preamble resource and/or PRACH resource.UE Preamble resource according to SeNB configuration and/or PRACH resource, on SeNB community, use is selected PRACH resource sends selected preamble code, and receives the RAR message of correspondence.Particularly, when During non-competing random access resource deficiency, instruction UE can be initiated competition random access procedure.

In above-mentioned flow process, the non-competing random access procedure that SeNB initiates, send out with SeNB in embodiment one The non-competing random access procedure risen is similar to, and is not described in detail in this.

Embodiment four

In the present embodiment, support that the UE that carrying separates is operated under MeNB and SeNB simultaneously, and respectively Carry out data transmission with MeNB and SeNB and process.

When UE has uplink demand at SeNB, UE is by the way of reporting instruction, on SeNB Row data transfer demands indicates, and notice MeNB UE has transmitting uplink data demand at SeNB；MeNB Report instruction information according to by this, UE demand is notified SeNB, SeNB perform CFRA or distribution UL resource.The instruction information reported, can be L1 signaling, such as special D-SR resource.

Pre-configured one section of special D-SR resource on MeNB PCell, this resource is the special money of SeNB Source, for making MeNB know the Stochastic accessing demand of SeNB.This resource can trigger UE at MeNB Carry out being allocated to UE during carrying separates, and preserved by UE.When UE has uplink at SeNB During demand, UE uses this special D-SR to send transmitting uplink data demand instruction information, MeNB This private resource receives transmitting uplink data demand instruction information, i.e. would know that this UE is at SeNB There is transmitting uplink data demand.

As it is shown in figure 9, in step 901, if UE has transmitting uplink data demand at SeNB, and The D-SR being in uplink loss state or corresponding SeNB between UE with SeNB community does not configures or D-SR Configuration failure, and still in uplink sync status between UE and MeNB community, then in step 902, UE is allocated to the D-SR private resource of this UE by MeNB, by sending transmitting uplink data demand Instruction information, notifies UE current state and transmitting uplink data demand to MeNB.In step 903～904 In, after MeNB receives on D-SR private resource and decodes this instruction information, send logical to SeNB Know message, this notification message may include that UE mark, non-competing Stochastic accessing triggering request etc.. This notification message can be L1 signaling, such as D-SR；Can also be the notification message (MeNB between base station SeNB UE can be notified according to the community of the SeNB shown in indication in transmitting uplink data demand instruction information Transmitting uplink data demand is had) in the community of the SeNB shown in this request message indication.

In step 905, if SeNB is according to the notification message of MeNB, and SeNB keep with The uplink sync status of UE, however, it is determined that this UE is presently in uplink sync status, then in step 906, For UE distribution UL resource or non-competing random access procedure, otherwise initiate to connect at random with the non-competing of UE Enter process.Particularly, when non-competing random access resource deficiency, instruction UE is initiated competition and connects at random Enter process.

In above-mentioned flow process, the non-competing random access procedure that SeNB initiates, send out with SeNB in embodiment one The non-competing random access procedure risen is similar to, and is not described in detail in this.

In sum, owing to UE is polymerized multiple base stations, the different bearer of UE separates and uploads at different base station Defeated, when UE has transmission UL demand data to SeNB, if can not in time this transmitting uplink data demand be led to Know to network side, will result in UE and will be unable to the UL data of SeNB send, reduce system and UE The problem of energy, it is therefore desirable to consider how to make network side know the method that this situation carries out processing.The present invention is real Execute example and particularly carry the scene of separation for the polymerization of many base stations, by obtaining upper in SeNB community of UE Row transmission resource needs situation, scheduling UE carries out uplink on SeNB community, solves this scene Under how to make network know UE UL data transfer demands and UL resource request, scheduling UL data transmission Problem, it is ensured that system and the performance of user.
