What scope was complete conveys to those skilled in the art.
For as previously mentioned, for the MMW networks of high band, due to millimeter wave transmission
Severe attrition, should perform more measurements in user equipment (UE) side and/or provide to base station
More information is for the transmission between UE and base station.
Compared with the 4G networks of rather low-frequency band, suggestion of the invention, in MMW nets
At least one in user profile in terms of following three being provided to base station from UE defined in network：
The channel quality of precoding indicates (Channel Quality Indicator, CQI) information, UE
The user state information of preferred associated beam index and resource index and UE.
Here, proposed above-mentioned user profile periodically or aperiodically can be sent out
Give base station.
Hereinafter, the information to this in terms of three is described in detail respectively.
The CQI of precoding
CQI information has reacted channel quality, represents and can be used with most 10% block error rate
The order instruction (Rank Indication, RI) of recommendation and pre-coding matrix instruction (Precoding
Matrix Indicator, PMI) receive downlink sharied signal channel (DLSCH) transmit most
Good modulation and encoding scheme.CQI supports the tune of downlink channel in 4G wireless access networks
Key player be act as when degree and transmission.In 4G networks, UE is obtained according to transmission mode
Channel measured value is with based on public reference signal (CRS) or channel state information reference signals
(CSI-RS) calculating CQI (document that sees reference [1]).
5G millimeter-wave systems (such as 28GHz frequency bands) are higher than the propagation loss in 4G network
About 20dB (document that sees reference [2]).In this case, Cell Edge User may not
CRS or CSI-RS for channel measurement can be successfully be detected to calculate CQI.In order to improve
Channel quality, the transmission beam used in millimetre-wave attenuator.
For this purpose, according to the first aspect of the invention, base station sends the reference of precoding to UE
Signal, UE can calculate CQI based on the reference signal of the precoding, and this is referred to as precoding
CQI.
Therefore, in millimeter-wave communication system, by supporting that the CQI of this precoding can
Realize the related scheduling of downlink channel and transmission.
Beam index and associated resource index
As described above, 5G millimeter-wave communication systems are a kind of networks based on wave beam.In order to carry
High link-quality, base station will scan its coverage with different transmission beams.Preferably, base
Stand and can perform time domain scanning, because this wave beam is the specific wave beam of cell and is broadband
Wave beam.
For this purpose, according to the second aspect of the invention, it is preferred that UE sends the UE to base station
Beam index and associated resource index.The preferred beam index of UE indicates that UE can be from
The beam index of the preferred wave beam that corresponding serving BS is received, resource index indicates corresponding
Preferred wave beam time-frequency location.
In one implementation, UE sends the preferred transmission beam indexes of the UE in advance to base station
Set and associated resource index set (such as time slot sets, Resource Block (RB) index
Deng).When base station receives the UE preferred transmission beam index set and associated resource
After index set, can (and may according to the beam index set and resource index set
Other UE these information), be transmitted to the UE with the preferred wave beam of the UE.
Fig. 1 shows the schematic diagram of single MMW cell transmissions of the invention.Fig. 2 shows
The schematic diagram of the example that the time-domain wave beam corresponding with Fig. 1 is selected is gone out.
During the beam scanning cycle, the UE in cell coverage area is by associated resource
Position detects its preferred wave beam.
For example, the UE1 and UE2 shown in Fig. 1 can be when as shown in Figure 2 different
Gap detects its preferred wave beam.As shown in Figure 2, it is assumed that in a beam scanning cycle,
Base station is using N number of transmission beam (wave beam 0, wave beam 1 ... ..., wave beam N-1) N number of
The MPS process is scanned successively in subframe (subframe i, subframe i+1 ... ..., subframe i+N-1)
Scope.UE1 detects its preferred wave beam in subframe i, and UE2 is detected in subframe i+2
Its preferred wave beam.
After preferred wave beam is detected, UE1 and UE2 respectively will be relative with the preferred wave beam
The beam index answered and its resource location (such as relative time slot position) within the scan period
It is sent to base station.Then, MMW base stations can according to the preferred wave beam of the UE and it is relative when
Gap position performs resource allocation and starts data transfer.
In a kind of preferred implementation, it is possible to use optimum subframe is supporting that fast beam is selected.
A kind of schematic diagram of the subframe structure for supporting fast beam to select is shown in Fig. 3.If UE
Using quick decoder, then the RS that UE can be for example based on precoding is in downlink control
Region detection its preferred wave beam, and its selection is fed back in corresponding uplink control region.
In this case, beam selection can be realized within the time cycle of a subframe.
On the other hand, for multiple cell dispose, UE can also using direct or indirect mode to
Its preferred beam index and associated resources index are fed back respectively in multiple base stations.Fig. 4 is illustrated
The schematic diagram of many MMW cell transmissions of the invention.Fig. 4 corresponds to intensive cell
The situation of deployment, one of UE can detect multiple neighbor cells, and UE can
It is connected to multiple MMW base stations (MMW base stations 1 as shown in Figure 4, MMW base stations
2 and MMW base stations are 3).
Similar with single cell deployment, UE can be adopting direct or indirect mode to each MMW
Base station is sent in advance for its preferred beam index with the communication between the MMW base stations
Set and associated resource index set.So as to each base station can be according to corresponding wave beam
Index set and associated resource index set, send corresponding preferably wave beam to the UE.
In this case, when UE detects one or more bases during the beam scanning cycle
Stand send preferred wave beam when, which can be by the ripple of the preferred wave beam of each base station for detecting
Beam is indexed and corresponding resource location is all sent to each base station.
In this realization, by the letter to the multiple beam index of base station feedback and resource index
Breath, can support low latency transmission, mobile subscriber's transmission and NLOS transmission etc..Its transmission
Scene is as described below.
Scene 1：Multiple MMW base stations send identical data to identical UE in identical subframe.
This can be used for Cell Edge User, mobile subscriber and NLOS and transmits to strengthen data transfer rate.
Fig. 5 (a) and 5 (b) show the multichain of support NLOS transmission of the invention
The schematic diagram of road transmission, Fig. 6 show the multichain for supporting user mobility of the invention
The schematic diagram of road transmission.
In Fig. 5 (a), in the link between subframe i+1, UE1 and MMW base stations 1
Break or be blocked, and MMW base stations 2 ... ..., between MMW base stations K and UE1
Link is normal.In Fig. 5 (b), in subframe i+1, UE1 and MMW base stations 1 and MMW
Link down between base station 2 is blocked, and MMW base stations 3 ... ..., MMW bases
The link stood between K and UE1 is normal.As can be seen that between MMW base stations and UE1 extremely
A rare active link can be used for continuous data transmission.
In figure 6, in each transmission subframe of UE1, MMW collection of base stations and UE1 it
Between have at least one effective service link.Accordingly, there exist an adaptive MMW base station
Set may be coupled to mobile subscriber to provide continuous data transfer.
Scene 2：Multiple MMW base stations send different data to identical UE in identical subframe
To further enhance transmission data transfer rate, this can be used for the UE with senior receiver to stream, such as
With based on aerial array serial interference elimination (Serial Interference Cancellation,
SIC) the UE of receiver.
Scene 3：Multiple MMW base stations different subframes to identical UE send different pieces of information with
The delay that reduction is produced in the time domain due to beam scanning.Fig. 7 is shown for given use
The schematic diagram that continuously transmit of the family using the low latency of multiple links.
User state information
In 5G millimeter wave networks, receive in the collateral data transfer rates held more than Gbps of UE,
And force to support the scene of a large amount of links.In this case, all or portion is known in base station
User state information is divided to be beneficial to optimized allocation of resources and data transfer.Therefore, according to this
3rd aspect of invention, UE is to MMW base station feedback user state informations.According to this
Bright, user state information can include other that user resources utilization state and the UE link
One kind in the information (such as ID and linking status etc.) of UE and the receiver type of UE or
It is various.
In one implementation, when UE receiver types of UE to base station feedback, base station
Data can be sent to the UE with the corresponding data transfer rate of the receiver type.For example, if
The receiver of UE1 is the SIC receivers based on aerial array, and this represents that UE1 can be with more
High data transfer rate receiving data, then base station can distribute multi-link transmission plan increasing to UE1
The experience of the strong user.
In another implementation, UE to base station feedback other UE (examples of the link of the UE
The adjacent UE of the such as UE) information (such as ID and linking status etc. of other UE of link).
In this case, base station and the UE link be blocked when, base station can be by should
Other UE of the link of UE come to the UE transmission datas, so as to support that NLOS is transmitted.
Fig. 8 shows the schematic diagram of the scene of support NLOS transmission of the invention.
As shown in Figure 8, for example in UE1 moves to the shade of tree and itself and MMW
LOS links between base station are blocked.This stop can for example using shown in Fig. 3
Frame structure and be quickly detected.Due to UE1 it has been reported that its linking with which of detecting
The information of other UE (such as UE2) (ID such as UE2, they consensus are total to
Enjoy resource index and their Link State etc.), base station can be in next subframe or other tune
To send data to UE1 via the UE2 of link in degree subframe.Further, UE1 can be with
To the multiple adjacent link UE of base station repeats and their state, so as to base station can utilize this
Some or all in a little link UE are aiding in the data transfer of UE1.
