Description
Technical field
The present invention relates to field of communication technology, more particularly, to a kind of power optical fiber to family bandwidth allocation methods and dress
It puts.
Background technology
In wireless communication system, transmitting terminal and receiving terminal can generally send and receive to obtain higher using more antennas are adopted
Rate.The principle of multi-antenna technology is that the multilayer transmission of match channels feature, signal are formed using some features of channel
Radiation direction it is very targeted, can effective lifting system performance, obtained without increasing on the basis of bandwidth and power
Significant performance boost, be a very promising technology, and the extensive use in current system.During multi-antenna transmission
Generally will be by precoding to concentrate signal radiation direction, the number of plies of precoding may be greater than equal to 1.Compared with common
Single antenna transmissions technology, the reference demodulation of multiple antennas can be much more complex.In traditional single antenna transmissions, it is only necessary to ensure data
It is that time-frequency location is relatively more neighbouring on the same antenna with reference demodulation pilot tone.And for multi-antenna transmission, pilot tone and data meeting
After precoding process, it is necessary to ensure that it is consistent to refer to the precoding for demodulating pilot tone with the precoding of data by physical channel
's.If precoding is different, for receiving terminal, can relatively accurately know with reference to demodulation pilot tone after logic letter
Road (precoding and physical channel) and data after logic channel between linear relationship.It is this to generally require downlink control letter
The notice of order can limit flexibility and bring larger control signaling expense.
In the LTE system of early stage, it is by the way of, based on CRS (Cell specific Reference
Resource) carry out with reference to demodulation, such as transmission mode 2 (diversity transmission mode), (the Open-Loop Spatial Multiplexing mould of transmission mode 3
Formula), transmission mode 4 (Closed-Loop Spatial Multiplexing pattern), transmission mode 5 (individual layer closed loop precoding pattern), transmission mode 6 is (multi-purpose
Family space multiplexing mode) etc. be all to use to carry out with reference to demodulation based on CR, this pilot tone that demodulates is dimension according to physical channel
Come what is designed, port number is generally equivalent to transmission antenna number, and maximum can be supported to 4 ports；This reference demodulation pilot tone is in itself
It is not do precoding, and needs to carry out precoding during data transmission, MIMO transmission is supported thereby using this demodulation pilot tone
Need the precoding W of the notice downlink when sending data every time.Assuming that CRS after be physical channel H, data then can be after H*
W, it is impossible to data reference demodulation directly be carried out using CRS.Since this modes of W to be notified can bring apparent control overhead, and
Precoding needs are selected from code book, in order to control overhead can only full bandwidth using identical precoding, this is very inflexible.
This mentality of designing is abandoned in later LTE evolution versions, introduces new DMRS (Demodulation Reference
Signal, demodulated reference signal).New DMRS mentalities of designing are using the precoding identical with data, and like this, DMRS can
Changed so that expense is accomplished to change with the number of plies, and specific precoding need not reuse additional signaling and be notified, with number
According to being consistent.Which type of precoding to be port number ordinary circumstance that is transparent, seeing using for terminal
Also it is fewer, it so can be flexibly many compared to pervious mode.Wherein, the pattern of CRS and DMRS can be shown in Fig. 1.
The downlink precoding that the MIMO transmission based on DMRS uses in LTE system in correlation technique have the characteristics that it is transparent,
For terminal demodulation, it is only necessary to which the DMRS port for receiving and estimating to define on the level of the transport layer can be directly used in demodulation, survey
Measure pilot tone and data after logic channel H*W, which type of has used in physical channel H and DMRS and data without knowing
Precoding W.Standard-complexity is enormously simplified in this way, and the processing of terminal is also very simple.On it is to be noted that
These features that face is mentioned are established on a basic assumption, i.e., using base-band digital precoding transmission/Baseband Receiver.
As number of antennas is more and more, pure base band precoding may bring huge cost, so as to radio frequency precoding sum number
It is following trend according to being used in mixed way for precoding technique.The more days hairs for the mixing precoding for using base band and radio frequency
Reception system is sent, mathematical model can be expressed as following formula：
Y=WBBWRFHFRFFBB+n
In model formation above, y is the wireless signal received, and dimension is the number N r of receiving unit RXU；N is
Interference and noise, dimension are also the number N r of receiving unit RXU (Receiver Unit, receiving unit)；WBBFor the base of receiving terminal
Band receives weights, and dimension is related with the number of plies of receiving unit RXU number Ns r and data；WRFFor the radio frequency reception weights of receiving terminal,
Dimension is related with the antenna element number in receiving unit RXU number Ns r and reception antenna group；FBBIt prelists for the base band of transmitting terminal
Code weight value, dimension are related with the number of plies of transmitting element TXU (Transmitter Unit, transmitting element) number N t and data；HFRF
For the radio frequency precoding weights of transmitting terminal, dimension and the antenna element number in receiving unit TXU number Ns t and transmission antenna group
It is related.
Due to HFRFAnd FBBVariation may cause optimal WRF, WBBVariation, therefore, it is necessary to notice HF additional againRF
And FBBInformation, this notice may be needed based on default code book, the design of code book, the expense of notice signaling, flexibility
Reduction can all be brought to the application of MIMO technology obviously to be limited.
It can be seen that for fairly simple base band/digital precode system, radio frequency weights W is sended and receivedRFAnd HFRF
All it is default fixed value (weights are used to determine the radiation direction of antenna in phased array antenna), so analysis gets up to compare
Simply；It is primarily upon how obtaining more accurately F during communication system PlaysBB, WBBIt can voluntarily be set by receiving terminal
Meter, in general due to WBBFlexibly can dynamically it change in each time-domain symbol, for a receiving terminal, frequent basis
(channel that physical channel and precoding are multiplied, is here W for its logic channel estimatedRFHFRFFBB) optimal to calculate
Baseband Receiver weights, then using the weights carry out receive obtain good performance.Since what having used regardless of transmitting terminal
Data precoding FBB, since DMRS pilot tones also use identical precoding FBB, therefore logic channel can be always reflected in
It demodulates on pilot tone DMRS, can be transparent for terminal so as to send radio frequency/base band precoding, without informing terminal.
However, after radio frequency precoding is introduced, for radio frequency precoding/reception weights, since it is generally by radio frequency
On phase shifter realize that and on each time quantum, it is necessary to just set fixed value before signal is received, which connects
Value of retaking the power while for DMRS pilot tones and data-signal.Comparison discovery, Baseband Receiver weights are carried out with Baseband Receiver processing procedure
Reception signal then can be first cached unlike this, handled again after the completion of channel estimation, and radio frequency precoding cost of implementation is low,
The problem of signal reprocessing in each antenna element cannot be cached, therefore be present with one newly is exactly that receiving terminal cannot be known
It goes to determine optimal WRF again afterwards, then the system for including variable radio frequency precoding for one cannot be again as base band precoding one
The flexibility with the transparency and precoding selection of sample.
HFRFAnd FBBVariation may cause optimal WRF,WBBVariation, so as to need again additional notice HFRFAnd FBB
Information, this notice may be needed based on default code book, the design of code book, the expense of notice signaling, the reduction of flexibility
It will bring to the application of MIMO technology and obviously limit.
