The method and device that a kind of determining serving BS, measurement report
Technical field
The present invention relates to the method and devices that field of communication technology more particularly to a kind of determining serving BS, measurement report.
Background technique
In the prior art, multipoint cooperative communication system (CoMP) scene 4 includes macrocellular and low-power RRH (Remote
Radio Head, remote radio head) constitute heterogeneous network.Low-power RRH, each RRH shape are distributed in macrocell coverage area
At cell identical with macrocell, cell ID (Cell ID) having the same, macrocell and the identical public affairs of RRH common transport
Pilot tone altogether, such as do not belong between CRS (Cell-specific reference signals, cell-specific pilot signal), RRH
Switch in cell.
Channel state information reference signals (Channel State Information-Reference Signal, CSI-
RS it) can be used for the RRM (Radio Resource Management, wireless resource management) of macrocell and RRH in CoMP scene 4
Measurement and channel state information (CSI) measurement.High level is that the RRH in measuring assembly configures CSI-RS resource, i.e. non-zero power
The resource of CSI-RS, including resource distribution ID, antenna port number, sub-frame configuration, pseudo-random sequence generate parameter etc., survey for UE
Reporting status information of channel is measured, the transfer point number for the measuring assembly that standard is supported at present is up to 3.Meanwhile high-rise is also survey
RRH configuration CSI interference measurement (CSI-IM) resource, including resource distribution ID, sub-frame configuration in duration set etc., cooperation RRH exists
It is silent in CSI-IM resource, thus channel feedback when supporting multipoint cooperative.
Currently, ideal backhaul link may be implemented with the macro station in the range of station and fiber direct connection between RRH
(backhaul), it is able to carry out the cooperation of layer one (L1) interference control hierarchy.However, macro station, RRH within the scope of different macro stations it
Between not can be carried out L1 cooperation, cooperate range and cooperation set in number of base stations it is less.
Resource distribution of the CSI-RS in 8 antenna port is 5~8 kinds, and sub-frame configuration is 5~80 kinds, and pseudo-random sequence is
504 kinds, it can support the identification and measurement of 12600~322560 RRH.However, CSI-RS RE (Resource Element, money
Source element) resource distribution is identical, and under the same subframe, RRH only is distinguished with pseudo-random sequence, measurement accuracy is extremely difficult to and wants
It asks.Therefore, it is necessary to guarantee to be staggered on running time-frequency resource, measurement accuracy is improved, can support the identification and survey of 25~640 RRH in this way
Amount.Sub-frame configuration type is more, it is meant that and the sending cycle of CSI-RS is longer, for example 80 kinds of corresponding sending cycles are 80ms, compared with
Long sending cycle is suitble to RRM measurement, and is not suitable for CSI measurement.When sending cycle is 5ms, supported RRH number is at least
25 kinds.Therefore, current CSI measurement mechanism may not be able to support the measurement of more base station.
Under super-intensive networking scene, such as the larger office building of high flow capacity, intensive rally of magnanimity connection etc. are needed one
The base station that deployment quantity is extremely more in range is determined to provide service, to reach the need of higher flux density and user experience rate
It asks.The following are the performance indicators of office scenarios:
Flux density 15T/2T bps/Km2;
User experience rate 1G/0.5G bps;
Connect 0.75/m2 of number density.
However, the identification of base stations and measurement mechanism of use may not be able to meet super-intensive networking under the existing network architecture
Identification and measurement demand under scene when numerous base station dense deployments.For example, an office building has multilayer (such as 20 floor), and every
Layer has multiple Administrative Areas (such as 2), 10 AP of dense deployment (Access Point, access point) in each Administrative Area,
So AP sum is 400.In such super-intensive network, base station number is more, if matched according to current CSI-RS resource
Mode is set, can not support the identification of base station in super-intensive network.

In the embodiment of the present invention, under super-intensive networking scene, such as the larger office building of high flow capacity, need a concentration
Node controls numerous base stations.C-RAN framework (baseband pool centralized processing+RRH remote radio) can be used, AP corresponds to RRH.One
All AP fiber direct connections in office building form a C-RAN, are different C-RAN between office building to a baseband pool,
As shown in Figure 4.Since an office building has multilayer, such as 20 layers, and every layer has multiple Administrative Areas, such as 2, each office
10 AP of dense deployment in region, then AP sum is 400 under same C-RAN.
Under super-intensive networking scene, the working frequency of base station be 6GHz hereinafter, typical working frequency range be 3.4GHz~
3.6GHz (LTE TDD Band 42), the exterior wall penetration loss between office building are 23dB, and the interior wall between Administrative Area penetrates
Loss is 5dB, also has biggish penetration loss between floor.Therefore, different office buildings are interior, different floors are interior, different Office Areas
Channel condition, signal intensity difference are larger between AP in domain, are not suitable for the cooperation for carrying out L1 interference control hierarchy.It can be by one
The Administrative Area of a certain floor of office building regards a collaboration region as, 10 AP composition cooperation set in collaboration region.
Under normal circumstances, 10 AP are disposed in the Administrative Area of 1000m2, AP station spacing is 10m.Using more dense portion
Management side formula, the Administrative Area of 1000m2 is interior to dispose 40 AP, and AP station spacing is 5m, and station spacing very little, is disposed very intensive at this time.
Embodiment one: the identification of base station under office scenarios, using existing reference signal (Reference Signal, RS)
Design.
Numerous AP in office building are controlled by the base station pond of a centralized node C-RAN, form the cell of a centralization,
Numerous AP are divided into multiple collaboration regions according to Administrative Area, the AP composition cooperation set in collaboration region, in collaboration region
Cooperation set is determined for each UE.
Under same C-RAN, since AP corresponds to RRH, it is analogous to CoMP scene 4, therefore, all AP under same C-RAN have
Identical public guide frequency (such as CRS) belongs to the same cell, Cell ID having the same.When there is multiple carrier waves, not
With CRS is emitted on frequency point, multiple cells are corresponded to, multiple cell number can be identical or different under each AP.
Due under same C-RAN, CRS be it is identical, collaboration region can not be distinguished with CRS, collaboration region includes cooperation
Set.Therefore, it may be considered which collaboration region is distinguished with specific CSI-RS resource is.Such as 20 floor of office building,
Every layer of 2 Administrative Area, totally 40 collaboration regions (Administrative Area).Identify collaboration region can using CSI-RS sending cycle compared with
Long configuration, such as CSI-RS sending cycle are 80ms, then CSI-RS configuration is at least 400, can therefrom select 40 kinds
As specific CSI-RS resource (i.e. new reference signal resource) collaboration region for identification.
In same collaboration region, 10 AP are disposed, maximum can dispose 40AP.It therefore, is that each UE is true in collaboration region
When fixed cooperation set, using the longer configuration of CSI-RS sending cycle, such as CSI-RS sending cycle is 40ms, then CSI-RS
Configuration at least be 200, can therefrom select 10 kinds or 40 kinds for determine cooperation gather.AP (example in UE cooperation set
Such as 6 in 10AP, 15 in 40AP) when carrying out L1 cooperation, using the shorter configuration of CSI-RS sending cycle, such as CSI-
RS sending cycle is 5ms, then CSI-RS configuration is at least 25, can therefrom select 6 kinds or 15 kinds of CSI-RS to be configured to
AP in identification cooperation set.The identification of AP can reuse CSI-RS resource configuration and sub-frame configuration in different collaboration regions, but
It is to be differentiated using different pseudo-random sequences.
Embodiment two: the identification of base station under office scenarios is designed using new reference signal resource.
Existing reference signal CRS and CSI-RS is used in embodiment one, is set based on the reference signal in existing LTE system
Meter.Under super-intensive networking scene, new reference signal design may be used in 5G system, such as broadcast channel, control are believed
Road is simplified, and identification of more running time-frequency resources for numerous base stations is vacated, then money of the new reference signal in 8 antenna port
Source configuration can be more, it might even be possible to be based on more antennas port (such as 16,32,64 etc.) Lai Jinhang resource distribution.
In addition, high band, such as working frequency 42-48GHz and 59-64GHz, physical layer frame knot may be used in 5G system
Structure, physical channel, reference signal can be carried out completely new design.Under new reference signal design, still it can use public
Pilot tone identifies the cell (AP under same C-RAN) of centralization, specific reference signals resource identification collaboration region, in collaboration region
Interior selection reference signal resource determines cooperation set, and reference signal resource is selected cooperate for identification the AP in gathering.
Embodiment three: the identification of intensive lower base station of gathering.
880 meters long from south to north of the Tian'anmen Square, thing is 500 meters wide, and for area up to 440,000 square metres, maximum can accommodate 1,000,000 people
Hold grand rally.Under the intensive rally scene of magnanimity connection, base station deployment is as shown in figure 5, in the intensive portion of square border base station
Administration, in square base station random placement several, station spacing be 20~100m.
The base station on four side of square can be formed into 4 C-RAN according to geographical location, the base station in square forms 1 C-
RAN.It is different with office scenarios, in intensive scene of gathering, without inner-outer wall, the penetration loss of floor, formation that can not be natural
Collaboration region, therefore, can taking human as the base station in certain area is divided in a collaboration region, form the collaboration region
Cooperation set.At this point, different specific CSI-RS resource can be used in the identification of collaboration region in adjacent C-RAN, it is adjacent
The identification that base station in set is gathered and cooperates in cooperation in collaboration region cannot reuse CSI-RS resource configuration and sub-frame configuration, only
There are cooperation set and cooperation set in the collaboration region for meeting certain isolation (occurrence can according to the actual situation depending on)
The identification of middle base station could reuse, and isolation refers to that path loss difference is more than pre-determined threshold between the borderline base station in collaboration region
(occurrence can basis lower than pre-determined threshold for (occurrence can according to the actual situation depending on) or the received signal power of measurement
Depending on actual conditions).
The specific embodiment of measurement mechanism is given below.
For using existing reference signal under office scenarios in embodiment one, illustrate base station under super-intensive networking scene
Measurement method.
Example IV: public guide frequency measurement.
Under same C-RAN, the CRS that all AP are sent on same frequency point be it is identical, UE by measure CRS can determine
The cell of which centralization is accessed, Cell ID and broadcast message are obtained.When there is multiple carrier waves, AP is sent out on different frequent points
CRS is sent, corresponds to multiple cells, the cell number under each AP can be identical or different.For example, AP1 is on frequency point f1, frequency point f2
CRS is sent, respective cell Cell1, cell Cell2, AP2 send CRS, corresponding Cell2, Cell3 on frequency point f2, frequency point f3,
AP3 sends CRS, corresponding Cell1, Cell2, Cell3 on frequency point f1, frequency point f2, frequency point f3.
Embodiment five: the measurement of collaboration region is determined.
Due under the same C-RAN, CRS be it is identical, a collaboration region (such as Office Area can not be distinguished with CRS
Domain).Therefore, it may be considered which collaboration region is distinguished with specific CSI-RS resource is.When UE is linked into one by CRS
Under C-RAN, network side to UE configure specific CSI-RS resource and measurement report condition (such as CSI-RS RSRP it is maximum on
Report), which collaboration region network side determines UE according to the corresponding collaboration region ID of the CSI-RS resource reported, as following
Shown in table one.All AP in collaboration region send CSI-RS in specific CSI-RS resource.
Table one: collaboration region table corresponding with the CSI-RS resource of measuring configuration
Which specific CSI-RS resource the measurement network side in UE period is configured with, when meeting condition, if such as meet: phase
CSI-RS RSRP > pre-determined threshold of this collaboration region the CSI-RS RSRP- of adjacent collaboration region, then report, network side becomes UE
It more arrives in new collaboration region.
The measurement period for determining collaboration region is the integral multiple of CSI-RS sending cycle, can be hundred Milliseconds, second grade etc..
Network side can configure the measurement period of determining collaboration region according to the moving condition of UE, if UE is static or slow movement,
The longer period can be configured, if UE is mobile very fast, the shorter period can be configured, to preferably support collaboration region
Variation.
In addition, network side can be informed by high-rise dedicated signaling (such as RRC information) for specific CSI-RS resource
UE, can also by broadcast message (such as SIB message), the period is sent over the broadcast, obtain after UE parsing and wherein carry
Specific CSI-RS resource (i.e. the measurement configuration information).
Embodiment six: the measurement of cooperation set is determined.
After determining UE in which collaboration region, network side is provided to the UE CSI-RS for configuring each AP in the collaboration region again
Source and measurement report condition, further determine that cooperation set, as shown in following table two.
Table two: AP table corresponding with the CSI-RS resource of measuring configuration in collaboration region
Measure report condition:
One, measurement amount meets thresholding, i.e., is greater than or equal to the measured value on first reference signal resource default
The measured value of the second threshold value (occurrence can be preset according to actual needs) reported as the first measurement result.
The measurement configuration information that network side is issued to UE, including CSI-RS resource, measurement ID, measurement amount, measurement event, the
Two threshold values etc.;
The measurement amount (such as RSRP of CSI-RS) of UE measurement APi (any AP) meets threshold requirement, such as RSRPi > x
DBm, wherein RSRPi indicates that the measured value of the measurement amount of APi, x indicate the second threshold value;
UE reports the corresponding measurement result of the AP for meeting threshold requirement, wherein the measured value comprising measurement ID, measurement amount
Deng;
Two, measurement amount meets difference threshold, i.e., measures the measured value on first reference signal resource with maximum
The measured value that the difference of value is less than preset third threshold value is reported as the first measurement result.
Network side gives UE sending measuring configuration information, including CSI-RS resource, measurement ID, measurement amount, measurement event,
Third threshold value etc.;
Difference between the measurement amount (RSRP of such as CSI-RS) and strongest APmax of UE measurement APi meets threshold requirement,
Such as RSRPmax-RSRPi < x dB;Wherein RSRPmax indicates greatest measurement, and RSRPi indicates the measurement of the measurement amount of APi
Value, x indicate third threshold value;
UE reports the corresponding measurement result of AP for meeting difference threshold requirement, wherein the survey comprising measurement ID, measurement amount

Three, the AP number that measurement reports meets preset value, i.e., to the measured value descending on first reference signal resource
Arrangement, takes top n measured value to be reported as the first measurement result;
Network side gives UE sending measuring configuration information, including CSI-RS resource, measurement ID, measurement amount, reports AP number
Preset value etc.;
UE arranges AP according to measured value (RSRP of such as CSI-RS) descending of measurement amount, successively selects since first
The corresponding measurement result of N number of AP;
UE reports the corresponding measurement result of this N number of AP, includes measurement ID, measured value of measurement amount etc..
The method of cooperation set is determined in the present embodiment for example:
One, the difference threshold based on measurement amount, i.e., by measured value in first measurement result and the greatest measurement
Difference be less than preset difference threshold measured value corresponding to serving BS of the base station as the UE in the collaboration region.
The corresponding maximum measurement of the measurement amount of the measured value and strongest APmax that determine the measurement amount of the AP in cooperation set
Difference between value is less than preset difference threshold measured value;
The difference of measured value and the greatest measurement is less than AP corresponding to preset difference threshold measured value and made by UE
For the serving BS of UE described in collaboration region, if multiple AP, then these multiple AP form the cooperation set of UE;
For different UE, the AP number in the cooperation set based on difference threshold selection may be different, such as UE1
AP in cooperation set is { AP1, AP2 }, and the AP in the cooperation set of UE2 is { AP1, AP2, AP3 }.
Two, select the base station of predetermined quantity as described in that is, according to first measurement result based on cooperation cell number
The serving BS of the UE in collaboration region.
AP number in regulation cooperation set is certain, is equal to preset value (i.e. predetermined quantity);
UE reports the corresponding measurement result of the AP of predetermined quantity, and network side selects these AP to form the collaboration set of the UE
It closes;
For different UE, the AP number in the cooperation set based on predetermined quantity selection is identical, but AP may be different,
Such as the AP in UE1 cooperation set is { AP1, AP2 }, the AP in UE2 cooperation set is { AP2, AP3 }.
Three, the QoS (Quality of Service, service quality) based on UE business is tied according to first measurement
Fruit selects serving BS of the base station for meeting the quality of service requirement of the UE as the UE in the collaboration region.
According to the QoS of UE business, such as GBR (Guaranteed Bit Rate guarantees bit rate) or MinBR
(Minimum Bit Rate, minimum bit rate) determines the AP in cooperation set;
UE reports the corresponding measurement result of AP, wherein network side is according to UE comprising measurement ID, measured value of measurement amount etc.
The QoS of business, spectrum efficiency, system bandwidth, load and the measured value of measurement amount (such as RSRP) etc. of AP in collaboration region are
AP in UE selection cooperation set.
For UE, the transmission rate of the qos requirement of business is R bps, the spectrum efficiency of APi in collaboration region

AP is arranged according to load ascending order or is arranged according to RSRP descending, successively selects AP, the relatively more required transmission rate R and AP can
The AP of selection is formed the collaboration set of the UE until meeting transmission rate request by the transmission rate Xi*Wi* (1-Yi%) of offer
It closes.
In the present embodiment, UE can be with the CSI-RS resource of the measurement network side configuration in period, and the side UE, which meets, measures upper tape
Part report measurement results, network side is according to the measurement result reported, in conjunction with the criterion for determining cooperation set, judges whether to update UE
Cooperation set.When meeting is that UE redefines the measurement report condition that cooperation is gathered, network side updates the cooperation set of UE.
The measurement period for determining cooperation set is the integral multiple of CSI-RS sending cycle, can be Millisecond, hundred Milliseconds, second grade etc..
Network side can configure the measurement period for determining cooperation set according to the moving condition of UE, if UE is static or slow movement,
The longer period can be configured, if UE is mobile very fast, the shorter period can be configured, to preferably support in cooperation set

H), network side carries out uplink and downlink scheduling using the channel information of feedback, realizes that the data under the cooperation of L1 interference control hierarchy pass
It is defeated.
Since CSI-RS sending cycle is 5ms, the resource distribution under a subframe when 8 antenna port is at least 5 kinds, for
AP in cooperation set, it may be considered that be grouped them, under different subframes, a part of AP sends out CSI-RS, other all AP
It is silent.For example, there are 6 AP in UE cooperation set, when subframe 0, CSI-RS is sent out on the RE of AP0~AP2 resource distribution at 3 kinds;Son
When frame 1, CSI-RS is sent out on the RE of AP3~AP5 resource distribution at 3 kinds.AP0 is when sending out CSI-RS in resource distribution 0, AP1~AP5
It is silent in resource distribution 0, other AP and so on.
