Senior Long Term Evolution (LTE-Advanced abbreviates LTE-A as) system is the evolution system of future generation of LTE system.Fig. 3 is the LTE-A system carrier aggregation schematic diagram according to correlation technique, as shown in Figure 3, the LTE-A system adopts carrier aggregation (carrieraggregation) technological expansion transmission bandwidth, and the carrier wave of each polymerization is called one " component carrier " (component carrier).A plurality of component carriers can be continuous, also can be discontinuous, can be positioned at same frequency range (frequency band), also can be positioned at different frequency range.
In the LTE-A system, Physical Uplink Shared Channel can adopt the single antenna port transmission, also can adopt many antenna port transmission.Fig. 4 is the transmitting terminal base band signal process schematic diagram that adopts the Physical Uplink Shared Channel of many antenna port transmission according to the LTE-A system of correlation technique.When many antenna ports transmitted, LTE-A supported the spatial reuse based on one or two code word (Codeword abbreviates CW as), the corresponding transmission block TB of each code word.
When the spatial reuse transmission adopted based on two code words, from the transmission block to the code word, be mapped with dual mode, be respectively: TB1 is mapped to CW0, and TB2 is mapped to CW1; Be mapped to CW1 with TB1, TB2 is mapped to CW0.Wherein, the latter is called the intersection mapping from the transmission block to the code word.
Transmission block is mapped to after the code word, and code word will further be mapped to layer (layer), and each code word is mapped as one deck or two layer data.Before precoding, each layer data can be independently, parallel processing, also can adopt a layer interleaving technology (Layer Shifting, abbreviate LS as), the multi-layer data of spatial reuse is interweaved on orthogonal frequency division multiplexi (Discrete Fourier Transform Spreading OrthogonalFrequency Division Multiplexing the abbreviates DFT-S-OFDM as) symbol of a modulation symbol or a discrete Fourier expansion or a time slot.
When adopting two code word space multiplexing and when not doing layer and interweaving, two code words are carried out independently rate controlled, chnnel coding and modulation, distributing independent hybrid automatic repeat request process (Hybrid Automatic Repeat-reQuest process abbreviates HARQ process as); When adopt two code word space multiplexing, when using layer to interweave, two code words are spatially bound (Spatial Bundling), and identical modulation coding mode is arranged, and distribute a hybrid automatic repeat request process.
LTE-A adopts based on code book (codebook, be called code book again) linear predictive coding technology (precoding), that is, transmitting terminal utilizes channel condition information (Channel StatusInformation, abbreviate CSI as), carry out preliminary treatment (precoding) to transmitting.A kind of approach that transmitting terminal obtains CSI is the feedback by receiving terminal.In order to reduce feedback overhead, the general mode that adopts is to preserve identical code book, i.e. pre-coding matrix collection at receiving terminal with transmitting terminal.Receiving terminal is according to current channel conditions, in code book, select suitable pre-coding matrix, and with its pre-coding matrix index value (Precoding Matrix Index in code book, abbreviate PMI as) feed back to transmitting terminal, transmitting terminal finds pre-coding matrix according to the pre-coding matrix index value of feedback, carries out precoding to sending signal.
In the LTE-A up link, the base station is according to current channel conditions, in code book, select suitable pre-coding matrix, and with its pre-coding matrix index value PMI in code book together with some other uplink scheduling information, be carried in certain descending control information format, send to the user terminal of being dispatched through Physical Downlink Control Channel.User terminal finds pre-coding matrix according to the pre-coding matrix index value in the detected descending control information format, carries out precoding to sending signal.

In addition, in the LTE-A system, the Physical Uplink Shared Channel of user terminal in the one-component carrier wave can adopt continuous or discrete resource distribution mode.So-called continuous resource distributes, and promptly is similar in the LTE system, and the Physical Uplink Shared Channel of user terminal occupies one section continuous bandwidth in the one-component carrier wave; So-called discontinuous resource allocation, the Physical Uplink Shared Channel that is meant user terminal occupies the multistage bandwidth in the one-component carrier wave, these bandwidth are discontinuous, every section bandwidth comprises one group of continuous PRB, be called cluster (cluster), Fig. 5 is the schematic diagram according to the discontinuous resource allocation of PUSCH in the one-component carrier wave in the LTE-A system of correlation technique.
The Physical Uplink Shared Channel of discontinuous resource allocation can adopt the single antenna port transmission, also can adopt many antenna port transmission.
The discontinuous resource allocation of LTE-A system uplink can be with reference to the resource allocation of LTE system descending.The resource allocation of LTE system descending has 3 kinds of modes, and type 0, type 1 and type 2, and wherein, type 0 is the unit allocation of channel resources may with Resource Block group (Resource Block Group abbreviates RBG as).RBG is defined as one group of continuous PRB, and the big or small P of Resource Block group (RBG size, that is, the PRB number that comprises) be the function of system bandwidth.As shown in table 3, the LTE system bandwidth can be configured to 1.4MHz, 3MHz, and 5MHz, 10MHz, 15MHz, 20MHz, Dui Ying PRB number is 6,15,25,50,75,100 respectively.(PRB with correspondence counts N according to different system bandwidths RB DLRepresent), the size of Resource Block group is also different, that is, the granularity of resource allocation (granularity) difference, concrete condition sees Table 4.
