Description

Using the method and apparatus of unauthorized carrier wave

Technical field

The present invention relates to moving communicating field, more particularly to a kind of method and apparatus using unauthorized carrier wave.

Background technology

LTE (Long Term Evolution, the Long Term Evolution) system of 3GPP standard criterions, in Rel-12 Version introduces very important DC (Dual Connectivity, dual link) function so that single UE Can simultaneously and two LTE base station dominant bases (MastereNB, MeNB) and prothetic group station (Secondary, SeNB) carry out wireless connection and the transmitting-receiving of upstream and downstream user business datum is transmitted.

LTE DC mode of operations can provide three kinds of basic DRB (Data Radio Bearer, data without Line is carried) type, respectively MCG (Master Cell Group, main plot group) Bearer lead to Cross the downstream transmission that MCG realizes user service data；Mixing Split Bearer, i.e., by MCG With SCG (Secondary Cell Group, main plot group) while realizing the up-downgoing of user service data Transmission；SCG Bearer, i.e., realize the up-downgoing data transfer of user service data by SCG.

The LTE system of 3GPP standard criterions, introduces very important LAA again in Rel-13 versions (Licensed Assisted Access authorize frequency spectrum auxiliary to access) function, you can multiple with association aggregation Authorize carrier wave and unauthorized carrier resource.In the simplified framework of LTE LAA carrier aggregations, eNB Or UE is used as data transmit-receive end, N number of parallel mixing is configured with MAC protocol entity and is weighed automatically Pass request (Hybrid Automatic Repeat reQuest, HARQ) entity, wherein each HARQ Entity one carrier wave of correspondence, can carry out multiplexing process to the data block of a plurality of user service data stream, but A portion is traditional HARQ entities of authorization of service carrier wave, and another part is that service is unauthorized The LAA-HARQ entities of carrier wave；What N number of parallel HARQ entities simultaneously maximum can be produced/be received N number of HARQ data bag, a series of relevant treatment of each of which through correspondence physical layer PHY entity, The specific physical layer wireless signals of LTE are finally translated into, a portion is the service on carrier wave is authorized Received and dispatched in cell, main serving cell Pcell in such as MCG, main serving cell PScell in SCG, Or mandate auxiliary serving cell Scell in MCG/SCG, and another part then will be in unauthorized carrier wave On Serving cell in received and dispatched, the unauthorized auxiliary serving cell LAA Scells in such as MCG/SCG. Here traditional PHY entities be have also been made and the differentiation of LAA-PHY entities is improved, expresses for LAA Improvement in characteristic functions.Ideally, UE allows following LAA carrier aggregations to configure：

In Scell (the MCG)+MCG that several authorize in Pcell+MCG, several are unauthorized In Scell (the SCG)+SCG that several authorize in LAA Scell (MCG)+PScell+SCG several Unauthorized LAA Scell (SCG)；

For Pcell, Scell (MCG), PScell, Scell (SCG), due to being all configured in mandate carrier frequency On point, therefore the configuration of alien frequencies relation is operable to each other.Assume MeNB, SeNB and UE All possess LAA abilities, therefore MeNB deploy LAA increase-volume cells on certain unauthorized carrier wave 2, SeNB also deploys LAA increase-volume cells on certain unauthorized carrier wave 4, when UE enters into aforementioned LAA When increase-volume cell collectively covers region, MeNB further can configure a LAA for UE Scell (MCG) and Pcell combine and are LAA CA, and SeNB further can configure a LAA for UE Scell (SCG) and PScell combine and are LAA CA.If the WLAN AP node adjacent with MeNB With LAA Scell (MCG) are with frequency or have bandwidth of operation to overlap, then unauthorized load can be formed with MeNB The competitive relation of ripple resource, certain section of moment, if WLAN competitions are first robbed accounts for certain unauthorized carrier wave 2 On Radio Resource, then MeNB need backoff to go again to attempt preempting resources to the next moment, from And cannot be using LAA Scell (MCG) while carrying out data transmission with UE.It is adjacent with SeNB If WLAN AP nodes and LAA Scell (SCG) are with frequency or have bandwidth of operation to overlap, can be with SeNB forms the competitive relation of unauthorized carrier resource, certain section of moment, if WLAN competitions are first robbed Account for the Radio Resource on certain unauthorized carrier wave 4, then SeNB need backoff to the next moment again Go to attempt preempting resources, so as to LAA Scell (SCG) cannot be utilized while carrying out data transmission with UE. Therefore whether LAA Scell (MCG) and LAA Scell (SCG) can be used in data strengthens transmission, takes Certainly in local contention disturbed condition and the result of LBT.

Due to MeNB, SeNB can utilize LAA Scells (MCG) and LAA Scells (SCG) resource Premise be：Successfully pass local LBT operations, and whether successfully can depend on each of which periphery with The wireless competition interference environment of machine, therefore collaboration allows MeNB, SeNB to do LBT simultaneously, go to rob and gain all Unauthorized carrier resource more than possible, can increase total success rate that unauthorized carrier resource is seized.Otherwise If MeNB, SeNB compete preempting resources up in different unauthorized carrier waves independently of one another, then Success rate and utilization rate that unauthorized carrier resource is seized can not be maximized.

Below the method that the present invention is provided is described further：

The schematic diagram of the DC systems that Fig. 2 (a) is provided for the present invention.As shown in Fig. 2 (a)：Certain operation The macro base station of business A deploys macrocell covering on the mandate carrier wave 1 in certain region, and micro-base station is identical Deploy Microcell and cover on the mandate carrier wave 3 in subregion that macrocell is covered and (increase for power system capacity By force)；Certain moment UE enters the overlapping covered of grand Microcell, so as to MeNB determines to match somebody with somebody to UE DC mode of operations are put, now UE and MeNB set up primary link, complete to configure Pcell；UE and SeNB Auxiliary link is set up, completes to configure PScell (in the example and following example, to put it more simply, all ignoring Scell (MCG) and Scell (SCG))；Although also having multiple adjacent WLAN in macrocell is covered AP nodes, but as they are configured in the unauthorized frequency range for operate in alien frequencies, therefore they will not DC work operations to UE bring any air interference.

The schematic diagram of the DCC+LAA alien frequencies systems that Fig. 2 (b) is provided for the present invention.Such as Fig. 2 (b) It is shown：Assume that MeNB, SeNB and UE possess LAA abilities, therefore MeNB is unauthorized at certain LAA increase-volume cells (working frequency points and bandwidth are determined by oneself) are deployed on carrier wave 2, SeNB is at certain Also LAA increase-volume cells (working frequency points and bandwidth are determined by oneself) are deployed on unauthorized carrier wave 4, When UE enters into aforementioned LAA increase-volumes cell collectively covers region, MeNB can be further UE configures a LAA Scell (MCG) and Pcell and combines and is LAA CA, and SeNB can be further UE configures a LAA Scell (SCG) and PScell and combines and is LAA CA.It is adjacent with MeNB If WLAN AP nodes and LAA Scell (MCG) are with frequency or have bandwidth of operation to overlap, can be with MeNB forms the competitive relation of unauthorized carrier resource, certain section of moment, if WLAN competitions are first robbed Account for the Radio Resource on certain unauthorized carrier wave 2, then MeNB need backoff to the next moment again Go to attempt preempting resources, so as to LAA Scell (MCG) cannot be utilized while carrying out data transmission with UE. If the WLAN AP node adjacent with SeNB and LAA Scell (SCG) are with frequency or have bandwidth of operation Overlap, then the competitive relation of unauthorized carrier resource can be formed with SeNB, certain section of moment, if The Radio Resource accounted on certain unauthorized carrier wave 4 is first robbed in WLAN competitions, then SeNB needs backoff Go again to attempt preempting resources to the next moment, so as to LAA Scell (SCG) cannot be utilized while and UE Carry out data transmission.Therefore whether LAA Scell (MCG) and LAA Scell (SCG) can be used in number According to transmission is strengthened, depending on local contention disturbed condition and the result of LBT.

Fig. 2 (c) for the DCC+LAA that provides of the present invention with display system schematic diagram.Such as Fig. 2 (c) It is shown：Assume that MeNB, SeNB and UE possess LAA abilities, therefore MeNB is unauthorized at certain Carrier wave 2, while deploying two LAA increase-volume cells on 4, unauthorized carrier waves 2 of the SeNB in same frequency, Also two LAA increase-volume cells are deployed on 4, is covered when UE enters into aforementioned LAA increase-volumes cell jointly When cover area, MeNB can configure two LAA Scells (MCG) and Pcell for UE and combine and do LAA CA, SeNB can configure two LAA Scells (SCG) and PScell for UE and combine and be LAA CA.And MeNB, if SeNB adjacent WLAN AP nodes and LAA Scells (MCG), LAA Scells (SCG) with frequency or have bandwidth of operation to overlap, then can and MeNB, SeNB form unauthorized load The competitive relation of ripple resource, certain section of moment, if WLAN competitions are first robbed accounts for unauthorized carrier wave 2,4 On Radio Resource, then MeNB, SeNB need backoff to go trial to seize money again to the next moment Source, it is impossible to which, using LAA Scells (MCG), LAA Scells (SCG) are while carry out data transmission with UE. Dramatically different point with Fig. 2 (b) is：In Fig. 2 (c), MeNB/SeNB is same is configured with multiple LAA frequently Auxiliary serving cell, it is shared to make use of all possible unauthorized carrier resource, without internal alien frequencies again Divide.

If LAA is Scells (MCG) and LAA Scells (SCG) are disposed with frequency and configured, they can not Carry out data transmission with UE in the same time period simultaneously；Due to there is X2 between MeNB and SeNB Terrestrial interface, or if physical distance is nearer between MeNB and SeNB, eating dishes without rice or wine to supervise each other Hear that other side is taking unauthorized carrier resource, thus can be with active avoidance, it is ensured that in certain time period Interior only one of which service eNB nodes and UE carry out data transmission, therefore MeNB and SeNB can join Close ground and utilize unauthorized carrier resource as much as possible in a time-multiplexed manner.Because MeNB, SeNB Using the premise of LAA Scells (MCG) and LAA Scells (SCG) resource can be：Successfully pass local LBT operations, and whether can successfully depend on the random wireless competition interference environment of each of which periphery, Therefore collaboration allows MeNB, SeNB to do LBT simultaneously, goes to seize unauthorized carrier resource as much as possible, Total success rate that unauthorized carrier resource is seized can be increased.If instead MeNB, SeNB are each only Preempting resources are competed up in different unauthorized carrier waves on the spot, then can not maximize unauthorized carrier resource The success rate seized and utilization rate.

Above-mentioned conclusion can be verified with a simple mathematical model below：

Assume on unauthorized frequency 2, there are 3 adjacent competition nodes (comprising adjacent LAA interference sections Point, adjacent WLAN interfering nodes etc.) competition of doing unauthorized carrier resource seizes, in unauthorized frequency There are 7 adjacent competition nodes on 4 (comprising adjacent LAA interfering nodes, adjacent WLAN interference Node etc.) competition of doing unauthorized carrier resource seizes.Each competition node can be with complete on respective frequency The fair mode of full statistics is gone to seize and uses corresponding unauthorized carrier resource.

According to the LAA alien frequencies configuration modes of Fig. 2 (b), MeNB is added to the competing of unauthorized frequency 2 Strive, therefore 1/4 occupancy/utilization rate can be obtained；SeNB adds the competition to unauthorized frequency 4, Therefore 1/8 occupancy/utilization rate can be obtained；So as to total occupancy is 1/4+1/8=3/8=0.375. This is the upper limit of UE under DC mode of operations to available unauthorized carrier resource utilization rate.

According to the LAA of Fig. 2 (c) with frequency configuration mode, MeNB and SeNB is added simultaneously and is awarded to non- The competition of power frequency 2, therefore 2/5 occupancy/utilization rate can be obtained；MeNB and SeNB are simultaneously Also the competition to unauthorized frequency 4 is added, therefore 2/9 occupancy/utilization rate can be obtained；So as to total Occupancy is 2/5+2/9=28/45=0.622.This is UE under DC mode of operations to available non- Authorize the upper limit of carrier resource utilization rate.Contrast from the examples above finds：MeNB and SeNB is having On the premise of cooperation condition, jointly simultaneously it is LBT on the unauthorized carrier wave of same frequency and resource is seized, Overall utilizations of the UE to unauthorized carrier resource under DC mode of operations can be improved.

In order to effectively support that DC+LAA is configured with frequency, it is necessary to solve the problems, such as following several crucial：Such as What carries out collaborations of the LAA Scell with frequency allocation activationHow LAA Scell is carried out with frequency operation association TogetherIn consideration of it, the invention provides a kind of terminal under dual link mode of operation is taken and is awarded using non- The method of power carrier resource, the key step and flow process being related to are as follows：

ENBs and UE possess while being the operation of LTE DC dual links and MeNB/SeNB to multiple non- Carrier wave is authorized to carry out the joint capability of LAA CA operations.UE is configured with frequency in being DC+LAA Physical region.

S1：MeNB and UE are measured by respective RSSI/RRM first, available to all candidates The wireless load of machinery systems and pilot signal strength quality of the carrier wave in unauthorized frequency range does measurement assessment, is based on The result of measurement assessment, selectes the unauthorized carrier frequency point bandwidth of most suitable several targets, for quilt Service UE deployment/configuration/corresponding LAA Scells (MCG) of activation；Hereafter MeNB can pass through Pcell, Scells (MCG) and LAA Scells (MCG) Serving cell collection and UE carry out up-downgoing Data transfer, it then follows existing LAA CA operation principles.

S2：Similar S1, SeNB and UE are measured also by respective RSSI/RRM, to all candidates The wireless load of machinery systems and pilot signal strength quality of the carrier wave in available unauthorized frequency range does measurement assessment Due to SeNB with MeNB physical locations it is different, therefore measure the result of assessment may be different, based on survey The result of amount assessment, selectes the set of cells containing the unauthorized carrier frequency point bandwidth of initial several targets Initial_LAA_Scell_Set。

S3：MeNB notifies the selected LAA Scells of SeNB by the control message of X2 interface (MCG) unauthorized carrier frequency point and bandwidth information, and indicated by ordering：Whether SeNB is allowed Carry out the configuration of LAA same frequency service cells；

If it is allowed, then SeNB can be selected from Initial_LAA_Scell_Set and LAA Scells (MCG) with frequency or have the unauthorized carrier wave of several targets that fractional bandwidth overlaps, including completely or The situation that part and LAA Scells (MCG) Serving cells collection are overlapped.

If it is not allowed, then SeNB can only be selected from Initial_LAA_Scell_Set and LAA Scells (MCG) the complete unauthorized carrier wave of several targets of alien frequencies and no any bandwidth overlay, now LAA Scells (SCG) and LAA Scells (MCG) Serving cell collection do not have any frequency-portions to overlap, Here it is the deployment configuration mode of tradition CA alien frequencies.

SeNB determines subset from Initial_LAA_Scell_Set screenings according to above-mentioned control law: Target_LAA_Scell_Set disposes/configuration/corresponding LAA Scells (SCG) of activation to being serviced UE； Hereafter SeNB can pass through PScell, Scells (SCG) and LAA Scells (SCG) Serving cell collection Up-downgoing data transfer is carried out with UE, it then follows existing LAA CA operation principles.

Note：LAA Scells (MCG) and LAA Scells (SCG) Serving cell collection have following 3 kinds Fundamental relation：

Relation 1：In LAA Scells (MCG) and LAA Scells (SCG) all Serving cells it Between complete alien frequencies, (the deployment configuration mode of traditional CA alien frequencies is not to have any frequency-portions to overlap This patent problem to be solved)

Relation 2：In LAA Scells (MCG) and LAA Scells (SCG) some Serving cells it Between have a part alien frequencies, but while having part to overlap with frequency or component frequency (belongs to DC+LAA with frequency Configuration operation mode, is this patent problem to be solved)

Relation 3：In LAA Scells (MCG) and LAA Scells (SCG), all Serving cells are complete It is complete the same, all with frequency and whole frequency overlap (belongs to DC+LAA with frequency configuration operation mode, is This patent problem to be solved)

S4：In UE during mode of operations of the DC+LAA with frequency configuration operation, work as MeNB Or SeNB when finding that oneself some LAA Scells is inappropriate (such as without specific electric load it is higher or UE sides pilot signal strength is second-rate), can independently deexcitation/deletion/oneself configuration LAA Scells (MCG) or LAA Scells (SCG), but only when MeNB and SeNB is certain LAA Scells (MCG) and/or LAA Scells (SCG) all deexcitations on unauthorized carrier frequency point After/deletion, the UE just completely LAA Scells of deexcitation/delete on that physics frequency.

Wherein, from UE angles, same LAA Scell physics frequencies, can logically, 1 To have mapped more at least two auxiliary serving cells, i.e. LAA Scell (MCG) and LAA Scell (SCG).If expanding to more connections from DC dual links, then above-mentioned principle is equally suitable for, I.e. same LAA Scell physics frequencies, logically can have mapped more auxiliary clothes more 1 pair Business cell.As previously mentioned：In LAA Scells (MCG) and LAA Scells with frequency configuration and activation (SCG), on, in certain time period, a service eNB node and UE can only carry out the biography of data Defeated, MeNB and SeNB jointly can be worked in a time-multiplexed manner, therefore to non-between them Authorize the collaboration of carrier resource seizure condition critically important.If MeNB and SeNB each other physical distance compared with Closely, and other side can be listened to eat dishes without rice or wine signal transmitting situation, unauthorized carrier wave money is accounted for when certain eNB is robbed When source carries out data transmit-receive, another eNB is monitored by competing interference, successfully generally can not be led to Cross LBT, so as to will not seize simultaneously channel to UE bring transmitting-receiving interference, therefore MeNB/SeNB it Between can by eat dishes without rice or wine monitor nature collaboration on, this mode be referred to as base station between eat dishes without rice or wine nature collaboration.

In MeNB and SeNB, physical distance is farther out each other, it is impossible to or can only faintly listen to other side Eat dishes without rice or wine signal launch in the case of, as the passback time delay of the non-ideal Backhaul of X2 terrestrial interfaces exists Between 1ms-50ms, when the transmission delay of X2 is larger, MeNB/SeNB is having a go at LAA Scells When collaboration with frequency data transfer, in addition a side can not obtain in time other side successfully robbed account for it is non- Carrier resource is authorized so as to open the status information of data transfer, is touched so as to cause UE side datas to receive Hitting reduces with signal to noise ratio.UE can be passed through in such cases in the collaboration for eating dishes without rice or wine quickly to carry out data transmission, Data of the UE sides on the LAA Scells (MCG) and LAA Scells (SCG) of same frequency are avoided to connect Receive conflict.(guarantee that LAA is cooperateed with frequency when system regulation X2 passback time delays are higher than certain thresholding Real-time)：

S5：For LAA with frequency configure and activate those unauthorized carrier waves, when MeNB/SeNB wherein Successfully rob for one and account for local unauthorized carrier resource, and data transmit-receive is carried out to being serviced UE When, UE must pass through to authorize configuration in master or auxiliary serving cell PCell/PScell/Scell on carrier wave Physical control channel feeding back its receiving status information, inform another eNB node：UE is Jing is passed in the data that LAA Scells (MCG) or LAA Scells (SCG) are carried out with certain service eNB It is defeated, data dispatch transmission please should not be carried out within the identical period.

UE is included at least by the content of the physical control channel feedback eated dishes without rice or wine：

1：Current service eNB node (the i.e. LAA on which unauthorized carrier frequency point and bandwidth On Scells (MCG) and LAA Scells (SCG)) successfully rob and account for resource and carry out data biography It is defeated.

2：The situation of data block reception success or failure in the past period, such as ACK/NACK etc.

3：The situation of channel quality/state, CQI, CSI etc. in the past period.

4：Another eNB node whether is allowed to continue to seize with unauthorized carrier frequency point and bandwidth Resource, carries out independent scheduling and data transfer to the UE.

S6：By the feedback information of eating dishes without rice or wine of UE, notified party eNB has learned other side's service eNB After seizing and being currently in use specific unauthorized carrier resource, if being instructed to not allow to continue to seize together Resource on unauthorized carrier frequency point and bandwidth, then evade wait other side's service eNB for a period of time, treat which After release resource is finished, reattempt the unauthorized carrier resource that carries out same frequency seizes use；Such as Fruit is instructed to allow to continue to seize with unauthorized carrier frequency point and the resource in bandwidth, then may still attempt to Seize and use with the unauthorized carrier resource of frequency, and be based on the feedback such as ACK/NACK, CQI, CSI Information, carries out normal consistency and data transfer to the UE.
