Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of control method for transmitting signaling, network equipment and terminal.
Background technology
Insert (E-UTRA at third generation cooperative programme evolution global radio, Evolved UniversalTerrestrial Radio Access) in the system, linear predictive coding can use at down link and adopt under closed loop multiple-input and multiple-output (MIMO, the Multiple Input Multiple Output) transmission means.The down link of E-UTRA system adopts OFDM (OFDM, Orthogonal Frequency DivisionMultiplexing) as basic modulation technique, and the processing procedure that the transmitting terminal of this system carries out linear predictive coding as shown in Figure 1.
Packet behind the coding is modulated, and will modulate the signal that generates and be mapped on n the layer (Layer) according to certain rule, the number of the middle column vector of the quantity n of layer and pre-coding matrix (PM, Precoding Matrix) is equal.Wherein, the signal that is mapped on each layer can be from encoding block of same user or different encoding block (for example, encoding block 1 is mapped to layer# 1 and layer# 2, encoding block 2 is mapped to layer# 3 and layer#4), also can be (for example from the encoding block of different user, user 1 encoding block is mapped to layer# 1 and layer# 2, and user 2 encoding block is mapped to layer# 3 and layer#4).By selected pre-coding matrix the modulation signal on each layer is carried out linear predictive coding, obtain m road spacing wave, m equals the number of transmitting antenna, and each road spacing wave sends from a transmit antennas through resource mapping and OFDM modulation again.
Usually the realization of linear predictive coding depends on measurement and the corresponding feedback of user to channel quality, and implementation procedure comprises following step:
(1), the user measures the down channel between every group of dual-mode antenna by descending public reference signal.
(2), the user selects the optimum linear predictive coding matrix that is used for the multi-layer data flow transmission according to the channel condition of measuring, or is used for the linear predictive coding vector of single layer data flow transmission in setting code book.
(3), the user gives the base station with the sequence number (PMI, Precoding Matrix Index) and order (rank) information of the linear predictive coding matrix of selection by uplink feedback.Wherein, PMI is the sequence number of linear predictive coding matrix in setting code book, such as PMI=1, just represents the 1st PM in the code book.Rank represents the number of column vector among the PM, sets in the code book at one, can have the different PM of rank.
(4) base station receives the PMI and the rank information of user feedback, and selects down link to carry out the PM that linear predictive coding adopted.
(5) base station sends the PMI and the rank information of data of passing through linear predictive coding and the PM correspondence that is adopted.
(6) user terminal is decoded according to the data of PMI that receives and rank information butt joint receipts.
The E-UTRA system with the whole system bandwidth evenly be divided into some Resource Block (RB, resourceblock), the frequency domain width of each RB is 12 subcarriers, the time length of field be a time slot, and be that unit is that the user divides the resource that is used in transfer of data with RB.Because wireless fading channel has frequency selectivity, just the channel fading situation is with frequency change, and therefore, the channel condition of each RB is different, and is also possible different with the optimum linearity pre-coding matrix that channel condition is corresponding.When a user distributes a plurality of RB, can select corresponding optimum linearity pre-coding matrix according to the channel condition of each RB, realize the frequency domain adaptive linear predictive coding.
In order to reduce the resource overhead of user profile feedback, can preestablish the frequency domain feedback granularity of PMI according to system bandwidth, for example, when system bandwidth is 1.25MHz or 2.5MHz, the feedback granularity is the whole system bandwidth, and at this moment, each user only need feed back the PMI information of a full range band; When system bandwidth is 5MHz, 10MHz or 20MHz, the Resource Block group (RBG, RB group) that the feedback granularity can be formed for several (as 4,5 or 6) RB continuously, at this moment, the user will feed back the PMI information of the different RBG of a plurality of correspondences.
After the channel condition and PMI information of user feedback received in the base station, at first between the user, carry out resource allocation according to channel condition and dispatching algorithm; Then, packet is carried out linear predictive coding, send to each user by the data-signal of many antennas after with linear predictive coding.Because therefore the linear predictive coding matrix that field feedback exists bigger error probability and base station can directly set each user according to the scheduling situation, not necessarily adopts the linear predictive coding matrix of user feedback when linear predictive coding is carried out in the base station.For the reliability that guarantees that user data receives, its actual which linear predictive coding matrix that adopted also must be notified the user in the base station when issuing data.Concrete advice method has two kinds:
A kind of is to insert dedicated pilot in the data channel resource of distributing, dedicated pilot carrying PM information (promptly dedicated pilot signal being carried out linear predictive coding), the user carries out channel estimating by the equivalent channel of dedicated pilot after to linear predictive coding, perhaps carry out channel estimating, detect the PM that dedicated pilot adopts again by public guide frequency.This method need extra pilot-frequency expense, and when carrying out the multiple data stream linear predictive coding (rank＞1), the detection performance of PM information can't guarantee.
Another kind of mode is the PMI of the PM that adopted to user's explicit notification by descending control signaling, for example, if the corresponding different respectively rank of predefined 16 linear predictive coding matrixes in the code book, then with 4bit indication PMI and rank information.If user data adopts frequency domain adaptive linear predictive coding mode, be positioned at the different feedback RB that RBG distributed and may adopt different linear predictive coding matrixes, then need to indicate a plurality of PMI to a user.User's PMI information total length can change along with quantity and the different of position for the RB of its distribution, if dispatching mutually with other PMI information of variable-length, related control information is carried on Physical Downlink Control Channel (PDCCH together, Physical downlink controlchannel) transmission in, can cause PDCCH to have the various control signaling format, make and the complex structure of PDCCH also increased the complexity that the user detects the control signaling simultaneously.
A kind of PMI transmission of Information method based on descending control signaling is arranged at present, the prior art is in the RB that distributes for the user, specify the interior part resource of one of them RB as Dedicated Control Channel, be used for the PMI information of transmission user, this Dedicated Control Channel adopts the open loop diversity mode of Space Frequency Block Coding (SFBC, SpaceFrequency Block Coding) to send PMI information.Because the resource of distributing to the user is channel condition RB preferably or preferably, therefore PMI transmit to obtain good frequency domain dispatching and gain in data resource.
Above-mentioned prior art is no matter the length of PMI is fixedly or variable, the capital is by all PMI information of resource transmission of transmission data, but, the prior art can not be carried out linear predictive coding to PMI information in the RB of appointment, can only adopt the open loop diversity mode to send PMI information, therefore, transmission PMI can not utilize linear predictive coding during information, obtains better performance gain.
In addition, when having only a PMI message transmission to give the user, for example under the multiuser MIMO situation, can not adopt the frequency domain adaptive linear predictive coding, all adopt same linear predictive coding matrix on the Resource Block of all distribution, the length of PMI information is several bit indications of fixing, and the prior art also will be utilized Dedicated Control Channel transmission PMI information in this case, be other control signaling separate processes and transmission of PMI information and this user, the complexity that like this will the increase system realizes.
