Uplink scheduling information is carried on Physical Downlink Control Channel, sends to target UE with certain descending control information format (Downlink Control Information format abbreviates DCI format as) by the base station.In the LTE system; Descending control information format is divided into following several kinds: DCI format 0,1,1A, 1B, 1C, 1D, 2,2A, 3, and 3A etc., wherein; DCI format 0 comprises uplink scheduling information, is used to indicate the scheduling of Physical Uplink Shared Channel PUSCH.
LTE-Advanced system (being called for short the LTE-A system) is the evolution system of future generation of LTE system.In the LTE-A system, Physical Uplink Shared Channel can adopt the single antenna port transmission, also can adopt many antenna port transmission.Fig. 3 is the sketch map of the transmitting terminal base band signal process of the LTE-A system of the correlation technique Physical Uplink Shared Channel that adopts the transmission of many antenna ports; As shown in Figure 3; When many antenna ports transmitted, the LTE-A system supported the spatial reuse based on one or two code word (Codeword abbreviates CW as); The corresponding transmission block (Transport Block abbreviates TB as) of each code word.Fig. 4 is the mapping sketch map that the up code word of the LTE-A system of correlation technique arrives layer, and is as shown in Figure 4, and code word will further be mapped to layer (layer), and each code word is mapped as one deck or two layer data.
LTE-A adopts based on code book (Codebook; Be called code book again) linear predictive coding technology (Precoding); Precoding technique is that a kind of channel condition information (Channel Status Information abbreviates CSI as) that utilizes carries out preliminary treatment to improve the technology of multiaerial system performance at transmitting terminal to signal.A kind of approach that transmitting terminal obtains CSI is the feedback through receiving terminal.In order to reduce feedback overhead, the general mode that adopts is to preserve identical code book at receiving terminal with transmitting terminal.Receiving terminal is according to current channel conditions; The pre-coding matrix that in code book, select to be fit to and with its index value (Precoding Matrix Index in set; Abbreviate PMI as) feed back to transmitting terminal; Transmitting terminal finds pre-coding matrix according to the pre-coding matrix index of feedback, and carries out precoding to sending signal.The Mathematical Modeling of data precoding is y=HWs+n, and wherein, y is for receiving signal phasor, and H is a channel coefficient matrix, and W is a pre-coding matrix, and s is a signal phasor, and n is a noise vector.
In the LTE-A system, when Physical Uplink Shared Channel adopted many antenna ports to transmit, the DMRS of each layer data equally carried out precoding with each layer data.And the demodulated reference signal of different layers data; Comprise demodulated reference signal to the multi-layer data of the same subscriber equipment of single user's multi-input multi-output system (SU-MIMO); And the demodulated reference signal of the multi-layer data of a plurality of subscriber equipmenies of multiuser mimo system (MU-MIMO); Through using different demodulated reference signal cyclic shifts (CS) and/or quadrature mask (Orthogonal Cover Code; Abbreviate OCC as) carry out orthogonalization, to distinguish the multiplexing different layers data of user's space or to distinguish different users.Wherein, quadrature mask OCC is [+1 ,+1] and [+1 ,-1], acts on the demodulated reference signal on interior two time slots of a sub-frame (Subframe) (Slot).
