Description

A kind of determine serving BS, measure the method that reports and device

Technical field

The present invention relates to communication technical field, particularly relate to and a kind of determine serving BS, measure the method that reports and device.

Background technology

In prior art, the heterogeneous network that multipoint cooperative communication system (CoMP) scene 4 includes macrocellular and low-power RRH (RemoteRadioHead, remote radio head) is constituted.Distribution low-power RRH in macrocell coverage area, each RRH forms the community identical with macrocell, there is identical cell ID (CellID), the public guide frequency that macrocell is identical with RRH common transport, such as CRS (Cell-specificreferencesignals, cell-specific pilot signal), it is not belonging to community switching between RRH.

Channel state information reference signals (ChannelStateInformation-ReferenceSignal, CSI-RS) can be used for the RRM of macrocell and RRH in CoMP scene 4 (RadioResourceManagement, RRM) to measure and channel condition information (CSI) measurement.High level is that the RRH in measuring assembly configures CSI-RS, the i.e. resource of non-zero power CSI-RS, parameter etc. is generated including resource distribution ID, antenna port number, sub-frame configuration, pseudo-random sequence, measuring reporting status information of channel for UE, the transmission point number of the measuring assembly of current standard support is 3 to the maximum.Meanwhile, high level is also that the RRH in measuring assembly configures CSI interferometry (CSI-IM) resource, and including resource distribution ID, sub-frame configuration etc., cooperation RRH mourns in silence in CSI-IM resource, thus channel feedback when supporting multipoint cooperative.

At present, with fiber direct connection between the macro station within the scope of station and RRH, it is possible to achieve desirable back haul link (backhaul), it is possible to carry out layer one (L1) and disturb the cooperation of control hierarchy.But, L1 cooperation, cooperation scope and the number of base stations in cooperation set can not be carried out between macro station within the scope of different macro stations, RRH less.

The CSI-RS resource distribution when 8 antenna port is 5～8 kinds, and sub-frame configuration is 5～80 kinds, and pseudo-random sequence is 504 kinds, can support identification and the measurement of 12600～322560 RRH.But, CSI-RSRE (ResourceElement, resource element) resource distribution is identical, under same subframe, only distinguishes RRH by pseudo-random sequence, is extremely difficult to certainty of measurement requirement.Accordingly, it would be desirable to guarantee running time-frequency resource staggers, improve certainty of measurement, so can support identification and the measurement of 25～640 RRH.Sub-frame configuration kind is more many, it is meant that the transmission cycle of CSI-RS is more long, and such as 80 kinds corresponding transmission cycles are 80ms, and the longer transmission cycle is suitable for RRM and measures, and is not suitable for CSI and measures.When the transmission cycle is 5ms, supported RRH number is minimum is 25 kinds.Therefore, current CSI measurement mechanism may not support the measurement of more base station.

Under super-intensive networking scene, for instance the larger office building of high flow capacity, the intensive rally etc. that magnanimity connects, it is necessary to the base station disposing quantity extremely many within the specific limits provides service, to reach higher flux density and the demand of Consumer's Experience speed.It is below the performance indications of office scenarios:

Flux density 15T/2Tbps/Km2；

Consumer's Experience speed 1G/0.5Gbps；

Connect 0.75/m2 of number density.

But, under the existing network architecture, the identification when identification of base stations of employing and measurement mechanism may not meet numerous base station dense deployment under super-intensive networking scene and measurement demand.Such as, an office building has multilamellar (such as 20 floor), and every layer has multiple Administrative Area (such as 2), 10 AP of dense deployment (AccessPoint, access point) in each Administrative Area, then AP adds up to 400.In such super-intensive network, base station number is more, if according to current CSI-RS configuration mode, it is impossible to support the identification of base station in super-intensive network.

Detailed description of the invention

In mobile communication system future development, in order to better meet user's request, significant increase network capacity and handling capacity, the access node of the little covering of more low-power will be introduced, namely future is super-intensive network.The embodiment of the present invention proposes, and in super-intensive network, a centralized node controls multiple base stations.Each base station under the control of same centralized node forms a concentrated area.Collaboration region is divided under concentrated area, collaboration region can have overlapping or not overlap, and can include a base station or multiple base station, wherein in collaboration region, the serving BS providing service for UE can be one or more, and these multiple serving BSs constitute the cooperation set of this UE.

The embodiment of the present invention is in super-intensive network, and centralized node is that base station determined by subscriber equipment (UserEquipment, UE), and its premise is to identify and measure its lower each base station controlled.In LTE-A (LongTermEvolution-Advanced, senior Long Term Evolution), identified by CSI-RS and measure base station.So, in super-intensive network, it is also possible to each base station being identified by CSI-RS and measuring under centralized node controls.

CSI-RS at least includes the resource distribution ID of CSI-RS, antenna port number, sub-frame configuration and pseudo-random sequence and generates parameter etc..Can supporting at most that at present CSI-RS, the CSI-RS of the 8 antenna ports resource distribution when 8 antenna port has 5～8 kinds, sub-frame configuration has 5～80 kinds, and pseudo-random sequence has 504 kinds.In the embodiment of the present invention, new reference signal resource can be adopted in order to carry out the identification of base station, new reference signal resource can be existing reference signal, broadcast channel and/or control the untapped running time-frequency resource of channel, and antenna port number corresponding to this new reference signal resource is more than 8.Thereby may be ensured that accuracy of identification, it is ensured that the new reference signal resource configured for each base station staggers on running time-frequency resource.

The detailed description of the embodiment of the present invention is provided below in conjunction with accompanying drawing.

Referring to Fig. 1, in centralized node side, a kind of method determining serving BS that the embodiment of the present invention provides, including:

S101, obtaining the first measurement result of reported by user equipment UE, this first measurement result is described UE to be reported after the measurement of base station in the collaboration region under concentrated area according to the first measurement configuration information；

S102, according to described first measurement result, it is determined that one or more serving BSs of described UE in described collaboration region.

In the embodiment of the present invention, a centralized node can control multiple base station, and centralized node can be a upper level node.Such as, independent access network node: local gateway (LocalGateway) or local controller (LocalController), or core net node, or Operations, Administration and Maintenance (OperationAdministrationandMaintenance, OAM) node；Can also being a base station, this base station be owing to can manage multiple base station, it is possible to regard super base station as；Can also be the baseband pool in C-RAN framework, focus on the baseband signal of multiple remote radio head (RemoteRadioHead, RRH).

Base station can be macro station, for instance eNB, NB etc.；Can also be small station, for instance low power nodes (LowPowerNode, LPN) pico, femto etc., access point (AccessPoint, AP)；Can also be the RRH in C-RAN framework.One or more community is had under one base station, under dense deployment scene, next one community, a usual base station, it is possible to be called small-cell.

If base station operation is in a center frequency point, then, this base station is divided into a community, the working frequency points of this community and the working frequency points (center frequency point) of base station.If base station operation is in two or more center frequency point, then, this base station is divided into two or more communities, and the quantity of community is the working frequency points quantity of base station, and the working frequency points of each community is a working frequency points of base station.

In the embodiment of the present invention, it is determined that the scheme of serving BS can have two kinds:

The first: centralized node can directly according to described first measurement result, it is determined that one or more serving BSs of described UE in described collaboration region；

The second: centralized node first obtains this UE the second measurement result reported, this second measurement result is to report after the collaboration region under concentrated area is measured by described UE according to the second measurement configuration information；According to described second measurement result, it is determined that the collaboration region at described UE place.Then perform step S101 and S102 then,.

But no matter adopt which kind of scheme, it is preferred that, determining that in described collaboration region after the serving BS of described UE, the method also includes:

It is preferred that described first measurement configuration information indicates the first reference signal resource that base station in collaboration region is corresponding；Described second configuration information indicates the second reference signal resource that collaboration region is corresponding；Wherein, the first reference signal resource that base stations different in same collaboration region is corresponding different, the second reference signal resource that different collaboration regions is corresponding different.

Described 3rd measurement configuration information indicates the 3rd reference signal resource that channel is corresponding.

The N number of measured value being taken on described first reference signal resource reports as the first measurement result, wherein, such as having M measured value on described first reference signal resource, take N number of measured value therein and report as the first measurement result, wherein M is more than or equal to N；Or,

Correspondingly, referring to Fig. 2, in UE side, the one that the embodiment of the present invention provides measures report method, including:

Base station in collaboration region under concentrated area is measured by S201, user equipment (UE) according to the first measurement configuration information, obtains the first measurement result；

S202, described UE report described first measurement result.

Described UE reports described second measurement result.

Described UE reports described 3rd measurement result.

Correspondingly, referring to Fig. 3, in base station side, a kind of method determining serving BS that the embodiment of the present invention provides, including:

S301, receiving the first measurement result of reported by user equipment UE, this first measurement result is described UE to be reported after the measurement of base station in the collaboration region under concentrated area according to the first measurement configuration information；

S302, described first measurement result is sent to centralized node.

Described second measurement result is sent to centralized node.

Receive described UE the 3rd measurement result measuring channel reported；

Wherein, high-level signaling is UE dedicated signaling, and arbitrary described measurement configuration information is sent to UE in RRC information；When adopting broadcast signaling, arbitrary described measurement configuration information is sent to UE in broadcast.

In the embodiment of the present invention, under super-intensive networking scene, for instance the larger office building of high flow capacity, it is necessary to a centralized node controls numerous base station.C-RAN framework (baseband pool focuses on+RRH remote radio), AP correspondence RRH can be adopted.All AP fiber direct connections to one baseband pool in one office building, forms a C-RAN, is different C-RAN, as shown in Figure 4 between office building.Owing to an office building has multilamellar, for instance 20 layers, and every layer has multiple Administrative Area, for instance 2,10 AP of dense deployment in each Administrative Area, then under same C-RAN, AP adds up to 400.

Under super-intensive networking scene, the operating frequency of base station is below 6GHz, typical working frequency range is 3.4GHz～3.6GHz (LTETDDBand42), exterior wall penetration loss between office building is 23dB, interior wall penetration loss between Administrative Area is 5dB, also has bigger penetration loss between floor.Therefore, between the AP in different office buildings, in different floors, in different Administrative Areas, channel condition, signal intensity difference are relatively big, are not suitable for carrying out L1 and disturb the cooperation of control hierarchy.The Administrative Area of an a certain floor of office building can be regarded as a collaboration region, 10 AP composition cooperation set in collaboration region.

Generally, disposing 10 AP, AP station spacings in the Administrative Area of 1000m2 is 10m.Adopting more dense deployment way, disposing 40 AP, AP station spacings in the Administrative Area of 1000m2 is 5m, and now station spacing is only small, disposes very intensive.

Embodiment one: the identification of base station under office scenarios, adopts existing reference signal (ReferenceSignal, RS) to design.

Numerous AP in office building are controlled by the pond, base station of a centralized node C-RAN, the community of one centralization of composition, numerous AP are divided into multiple collaboration region according to Administrative Area, the AP composition cooperation set in collaboration region, determine cooperation set for each UE in collaboration region.

Under same C-RAN, due to AP correspondence RRH, being analogous to CoMP scene 4, therefore, all AP under same C-RAN have identical public guide frequency (such as CRS), belong to same community, have identical CellID.When there being multiple carrier wave, launching CRS on different frequent points, corresponding multiple communities, under each AP, multiple cell number can be identical or different.

Owing to, under same C-RAN, CRS is identical, it is impossible to distinguish collaboration region with CRS, collaboration region comprises cooperation set.Therefore, it can consider which collaboration region distinguishes by specific CSI-RS is.Such as office building 20 floor, every layer of 2 Administrative Area, totally 40 collaboration regions (Administrative Area).Identify the configuration that collaboration region can adopt the CSI-RS transmission cycle longer, such as the CSI-RS transmission cycle is 80ms, so CSI-RS configuration is minimum is 400, it is possible to therefrom selects 40 kinds and is used for identifying collaboration region as specific CSI-RS (namely new reference signal resource).

In same collaboration region, dispose 10 AP, maximum dispose 40AP.Therefore, it is that each UE determining when cooperation is gathered in collaboration region, adopts the configuration that the CSI-RS transmission cycle is longer, for instance the CSI-RS transmission cycle is 40ms, then CSI-RS configuration is minimum is 200, it is possible to therefrom selection 10 kinds or 40 kinds is used for determining that cooperation is gathered.AP (6 in such as 10AP in UE cooperation set, in 40AP 15) carry out L1 cooperation time, adopt the configuration that the CSI-RS transmission cycle is shorter, such as the CSI-RS transmission cycle is 5ms, so CSI-RS configuration is minimum is 25, it is possible to therefrom 6 kinds or 15 kinds CSI-RS configurations of selection are for identifying the AP in cooperation set.In different collaboration regions, the identification of AP can reuse CSI-RS configuration and sub-frame configuration, but uses different pseudo-random sequences to differentiate.

Embodiment two: the identification of base station under office scenarios, adopts new reference signal resource to design.

Embodiment one adopts existing reference signal CRS and CSI-RS, is based on the reference signal design in existing LTE system.Under super-intensive networking scene, 5G system is likely to adopt new reference signal design, such as broadcast channel, control channel are simplified, vacate the identification for numerous base stations of the more running time-frequency resource, the resource distribution when 8 antenna port of the so new reference signal can be more, it might even be possible to carry out resource distribution based on more antennas port (such as 16,32,64 etc.).

Additionally, 5G system is likely to adopt high band, for instance operating frequency 42-48GHz and 59-64GHz, physical layer frame structure, physical channel, reference signal are likely to carry out brand-new design.Under new reference signal design, still the community (AP under same C-RAN) of public guide frequency identification centralization can be adopted, specific reference signals resource identification collaboration region, select reference signal resource to determine cooperation set in collaboration region, and select reference signal resource to be used for identifying the AP in cooperation set.

Embodiment three: the identification of base station under intensive rally.

880 meters long from south to north of the Tian'anmen Square, thing is wide 500 meters, and area reaches 440,000 square metres, maximum hold 1,000,000 people and holds grand rally.Under the intensive rally scene that magnanimity connects, base station deployment as it is shown in figure 5, at square border base station dense deployment, in square base station random placement several, station spacing is 20～100m.

According to geographical position, the base station on limit, square four can be formed 4 C-RAN, base station 1 C-RAN of composition in square.Different with office scenarios, in intensive rally scene, it does not have inner-outer wall, floor penetration loss, formation collaboration region that cannot be natural, therefore, it can artificial being divided in a collaboration region base station in certain area, form the cooperation set of this collaboration region.Now, in adjacent C-RAN, the identification of collaboration region can use different specific CSI-RS, in adjacent collaboration region, in cooperation set and cooperation set, the identification of base station can not reuse CSI-RS configuration and sub-frame configuration, only meet the identification of base station during cooperation set and cooperation in the collaboration region of certain isolation (occurrence can be determined) are gathered according to practical situation just can reuse, isolation refers to path loss difference between borderline base station, collaboration region and exceedes the received signal power of pre-determined threshold (occurrence can be determined according to practical situation) or measurement lower than pre-determined threshold (occurrence can be determined according to practical situation).

The specific embodiment of measurement mechanism is given below.

In embodiment one, adopt existing reference signal under office scenarios, the measuring method of base station under super-intensive networking scene is described.

Embodiment four: public guide frequency is measured.

Under same C-RAN, the CRS that all AP send on same frequency is identical, and UE may determine that, by measuring CRS, the community accessing which centralization, obtains CellID and broadcast.When there being multiple carrier wave, AP sends CRS, corresponding multiple communities on different frequent points, and the community number under each AP can be identical or different.Such as, AP1 sends CRS, respective cell Cell1, community Cell2 on frequency f1, frequency f2, AP2 sends CRS on frequency f2, frequency f3, corresponding Cell2, Cell3, AP3 sends CRS, corresponding Cell1, Cell2, Cell3 on frequency f1, frequency f2, frequency f3.

Embodiment five: determine the measurement of collaboration region.

Owing to, under same C-RAN, CRS is identical, it is impossible to distinguish collaboration region (such as an Administrative Area) with CRS.Therefore, it can consider which collaboration region distinguishes by specific CSI-RS is.When UE is linked under a C-RAN by CRS, network side configures specific CSI-RS to UE and measures report condition (maximum the reporting of such as CSI-RSRSRP), according to the collaboration region ID that the CSI-RS reported is corresponding, network side determines UE is in which collaboration region, as shown in table below one.All AP in collaboration region send CSI-RS in specific CSI-RS.

Table one: collaboration region table corresponding to the CSI-RS measuring configuration

Which specific CSI-RS the Measurement Network side in UE cycle is configured with, when satisfying condition, if such as meeting: the CSI-RSRSRP > pre-determined threshold of this collaboration region of CSI-RSRSRP-of adjacent collaboration region, then reporting, UE is altered in new collaboration region by network side.

Determine the integral multiple that the measurement cycle is the CSI-RS transmission cycle of collaboration region, it is possible to be hundred Milliseconds, second level etc..Network side can configure the measurement cycle determining collaboration region according to the mobile status of UE, if UE is static or slowly moves, it is possible to configure the longer cycle, if UE moves comparatively fast, it is possible to configure the shorter cycle, thus better supporting the change of collaboration region.

Embodiment six: determine the measurement of cooperation set.

After determining UE is in which collaboration region, network side configures the CSI-RS of each AP in this collaboration region to UE again and measures report condition, further determines that cooperation set, as shown in table below two.

Table two: AP table corresponding to the CSI-RS measuring configuration in collaboration region

Measure report condition:

One, measuring amount meets thresholding, and the measured value being about on described first reference signal resource reports as the first measurement result more than or equal to the measured value of default the second threshold value (occurrence can be preset according to actual needs).

Network side, to the UE measurement configuration information issued, including CSI-RS, measures ID, measuring amount, measurement event, the second threshold value etc.；

UE measures the measuring amount (RSRP of such as CSI-RS) of APi (arbitrary AP) and meets threshold requirement, for instance RSRPi > xdBm, wherein RSRPi represents the measured value of the measuring amount of APi, and x represents the second threshold value；

Measurement result corresponding for the AP meeting threshold requirement is reported by UE, wherein comprises the measured value etc. measuring ID, measuring amount；

Two, measuring amount meets difference threshold, and the difference being about to the measured value on described first reference signal resource and greatest measurement reports as the first measurement result less than the measured value of the 3rd default threshold value.

Network side, to UE sending measuring configuration information, including CSI-RS, measures ID, measuring amount, measurement event, the 3rd threshold value etc.；

The difference that UE measures between measuring amount (RSRP such as CSI-RS) and the strongest APmax of APi meets threshold requirement, for instance RSRPmax-RSRPi < xdB；Wherein RSRPmax represents that greatest measurement, RSRPi represent the measured value of the measuring amount of APi, and x represents the 3rd threshold value；

The measurement result corresponding for AP meeting difference threshold requirement is reported by UE, wherein comprises the measured value etc. measuring ID, measuring amount.

Three, measure the AP number reported and meet preset value, namely to the measured value descending on described first reference signal resource, take top n measured value and report as the first measurement result；

Network side to UE sending measuring configuration information, including CSI-RS, is measured ID, measuring amount, is reported the preset value etc. of AP number；

UE, by AP measured value (RSRP such as the CSI-RS) descending according to measuring amount, selects measurement result corresponding for N number of AP successively from first beginning；

The measurement result that this is corresponding for N number of AP is reported by UE, comprises the measured value etc. measuring ID, measuring amount.

The present embodiment is determined the method for cooperation set such as:

One, based on the difference threshold of measuring amount, by the difference of measured value in described first measurement result and described greatest measurement less than the serving BS as UE described in described collaboration region of the base station corresponding to default difference threshold measured value.

Determine that the difference between the greatest measurement that the measuring amount of the measured value of measuring amount of AP in cooperation set and the strongest APmax is corresponding is less than default difference threshold measured value；

UE is using the difference of measured value and described greatest measurement less than the serving BS as UE described in collaboration region of the AP corresponding to default difference threshold measured value, if multiple AP, then these multiple AP form the cooperation set of UE；

For different UE, it is likely to difference based on the AP number in the cooperation set that difference threshold selects, for instance the AP in the cooperation set of UE1 is that { AP in the cooperation set of AP1, AP2}, UE2 is { AP1, AP2, AP3}.

Two, based on cooperation cell number, namely according to described first measurement result, the base station serving BS as UE described in described collaboration region of predetermined quantity is selected.

AP number in regulation cooperation set is certain, equal to preset value (i.e. predetermined quantity)；

Measurement result corresponding for the AP of predetermined quantity is reported by UE, and network side selects these AP cooperation set forming this UE；

For different UE, identical based on the AP number in the cooperation set that predetermined quantity selects, but AP is likely to difference, for instance and the AP in UE1 cooperation set is that { AP in AP1, AP2}, UE2 cooperation set is { AP2, AP3}.

Three, based on the QoS (QualityofService, service quality) of UE business, namely according to described first measurement result, select the base station meeting the quality of service requirement of described UE as the serving BS of UE described in described collaboration region.

QoS according to UE business, for instance GBR (GuaranteedBitRate, it is ensured that bit rate) or MinBR (MinimumBitRate, minimum bit rate), it is determined that the AP in cooperation set；

Measurement result corresponding for AP is reported by UE, wherein comprise the measured value etc. measuring ID, measuring amount, the network side QoS according to UE business, the measured value etc. of the spectrum efficiency of AP, system bandwidth, load and measuring amount (such as RSRP) in collaboration region, select the AP in cooperation set for UE.

For UE, the transfer rate of the qos requirement of its business is Rbps, and in its collaboration region, the spectrum efficiency of APi is Xibps/Hz, and system bandwidth is WiHz, and load is Yi%, and the measured value of measuring amount (such as RSRP) is Zidbm.UE can by AP according to the arrangement of load ascending order or according to RSRP descending, select AP successively, relatively more required transfer rate R and the available transfer rate Xi*Wi* of this AP (1-Yi%), until meeting transmission rate request, forms the cooperation set of this UE by the AP of selection.

In the present embodiment, UE can the CSI-RS of Measurement Network side configuration in cycle, UE side meets measures report condition report measurement results, and network side according to the measurement result reported, combines the criterion determining that cooperation is gathered, it may be judged whether the cooperation set of renewal UE.When meeting the measurement report condition redefining cooperation set for UE, network side updates the cooperation set of UE.Determine the integral multiple that the measurement cycle is the CSI-RS transmission cycle of cooperation set, it is possible to for Millisecond, hundred Milliseconds, second level etc..Network side can configure the measurement cycle determining cooperation set according to the mobile status of UE, if UE is static or slowly moves, it is possible to configure the longer cycle, if UE moves comparatively fast, the shorter cycle can be configured, thus better supporting the change of AP in cooperation set.

After determining cooperation set for UE, network side configures CSI-RS to the AP in this UE cooperation set, channel feedback channel information is measured (such as channel condition information CSI for UE, including RI, PMI, CQI etc., or channel matrix H accurately), network side utilizes the channel information of feedback to carry out up-downgoing scheduling, it is achieved L1 disturbs the data transmission under the cooperation of control hierarchy.

Being 5ms owing to CSI-RS sends the cycle, under a subframe, resource distribution during 8 antenna port is minimum is 5 kinds, for the AP in cooperation set, it may be considered that they being grouped, under different subframes, a part of AP sends out CSI-RS, and other all AP mourn in silence.Such as, having 6 AP in UE cooperation set, during subframe 0, AP0～AP2 sends out CSI-RS on the RE of 3 kinds of resource distributions；During subframe 1, AP3～AP5 sends out CSI-RS on the RE of 3 kinds of resource distributions.When AP0 sends out CSI-RS in resource distribution 0, AP1～AP5 mourns in silence in resource distribution 0, and other AP are by that analogy.

Embodiment eight: the measurement in switching.

Under same C-RAN, all AP have identical CRS, belong to same community, have identical CellID, are determined collaboration region and cooperation set by the CSI-RSRRM measurement in cycle, primary concern is that the change of AP in the change of collaboration region and cooperation set.Between different C-RAN, belong to different communities, it is necessary to consider corresponding switching criterion.Network side configures CRSRRM to UE and measures (such as RSRP, RSRQ measure and measure report condition), walks normal switching flow.When being switched to another C-RAN from a C-RAN, configure corresponding CSI-RSRRM to UE again inside the new C-RAN accessed and measure, carry out the collaboration region within new C-RAN and cooperation set-determination process.
