For example, the transmitting terminal in the embodiment of the present application can be terminal device 116 or terminal device 122, receiving end can be with It is the network equipment 102；In another example the transmitting terminal in the embodiment of the present application can be the network equipment 102, receiving end can be terminal Equipment 116 or terminal device 122, certainly, the embodiment of the present application is not limited in any way this, in equipment to equipment (device to Device, D2D) under scene, transmitting terminal and receiving end can be terminal devices, or in the scene for having trunking, Transmitting terminal or receiving end can be trunking.
The embodiment of the present application for ease of understanding, below in conjunction with the process for handling data in Fig. 2 simple declaration ofdm system Schematic diagram.The object of processing is code word.
The first step, transmitting terminal to code word (code word) scrambled (scrambling) or interweave first, generate scrambling Bit or interleaving bits.Scrambling is to carry out xor operation using the bit in a bit sequence code-aiming block, the bit sequence Length is identical with the bit number in code block, and interweaves and refer to that the bit in code-aiming block is resequenced.Generally, which can With using scrambling or interweave one kind, can also using scrambling and interweave combination, including first scramble interweaves afterwards or first intertexture or Scrambled operation, the case where in addition no may also scrambling or interweave.
Second step is mapped to modulation symbol to the scrambler bits or interleaving bits of the first step, wherein common mapping mode Including two-phase PSK (binary phase shift keying, BPSK) modulating mode, pi/2-BPSK modulating mode, four Phase phase-shift keying (PSK) (quadrature phase shift keying, QPSK) modulating mode, π/4-QPSK modulating mode, 16 are just It hands over amplitude modulation (quadrature amplitude modulation, QAM), 64QAM, 256QAM etc..
The corresponding modulation symbol sequence of each code block is mapped on one or more space propagation layers by third step.Transmission Layer mapping is commonly used in the situation of multi-antenna transmission.If terminal device uses single antenna transmissions, only one most space Transport layer.
4th step carries out spatial pre-coding processing to the modulation symbol after transport layer mapping, different transport layers is pre-processed Modulation symbol afterwards is mapped on different antenna ports.Assuming that have v space propagation layer and P antenna port, then it is corresponding Spatial domain precoding can be expressed as formula (1), and wherein V is pre-coding matrix, and V size is P × v, y(0)(i),y(1)(i),…y(v-1)It (i) is the modulation symbol of v space propagation layer, z(0)(i),z(1)(i),…z(P-1)It (i) is the modulation symbol after precoding.
5th step, the modulation symbol after precoding are mapped by resource particle (RE), are mapped on multiple RE.These RE Orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) modulation is then passed through, it is raw At OFDM symbol.OFDM symbol then passes through antenna port (antenna port) and launches.
Further, it in order to understand the embodiment of the present application, briefly describes in DFT-s-OFDM system and handles below with reference to Fig. 3 The schematic diagram of the process of data.Modulation of the Fig. 3 unlike Fig. 2, in the transport layer after the transport layer mapping of third step Symbol carries out discrete fourier (discrete fourier transform, DFT) transformation, and the symbol after DFT transform is reflected It penetrates on multiple RE, these RE are modulated by OFDM, generate DFT-s-OFDM symbol, and DFT-s-OFDM symbol passes through antenna port Launch.Processing mode in above-mentioned ofdm system and in DFT-s-OFDM system, which can be regarded as, generates two different waveforms Processing mode.
Under the scene of Fig. 2 or Fig. 3, there is interference in the data between different transport layers, therefore, the embodiment of the present application, and such as Shown in Fig. 4, the modulation symbol in transport layer after can mapping the transport layer in Fig. 2 unlike Fig. 2 utilizes pre- place Reason matrix is pre-processed, and different transport layers are pre-processed using different preconditioning matrixs, can be reduced transport layer and be passed The interference of modulation symbol between defeated layer.Optionally, the embodiment of the present application, as shown in figure 5, can be in Fig. 3 unlike Fig. 3 Transport layer mapping after transport layer on modulation symbol pre-processed using preconditioning matrix, obtain pretreated biography Modulation symbol on defeated layer, then carries out DFT transform to the modulation symbol in pretreated transport layer, and different transport layers use Different preconditioning matrixs are handled, and the interference of modulation symbol between transport layer and transport layer can be reduced.Below with reference to attached The method that figure specifically describes the processing data in the embodiment of the present application.
Fig. 6 shows the method 200 of the processing data of the embodiment of the present application, and this method can be executed by transmitting terminal, the party Method 200 includes:
Modulation symbol is mapped at least one transport layer by S210.Such as S210 can be the transmission in Fig. 4 and Fig. 5 Layer mapping step.
S220 determines first object preconditioning matrix in preconditioning matrix set, appoints in the preconditioning matrix set It anticipates two preconditioning matrix differences.
Optionally, the preconditioning matrix set includes at least a sparse matrix, and each column of the sparse matrix are extremely Include less a neutral element, or can will see neutral element as close to those of zero element.When in preconditioning matrix set Null element when matrix includes sparse matrix, when the sparse matrix is used to handle the modulation symbol of transport layer, in the sparse matrix Element can weaken the symbol being multiplied in modulation symbol with neutral element, in this way, the interference with other transport layer datas can be reduced, and And receiving end solve that pretreated process is relatively easy, can reduce the complexity of system.
Optionally, in the preconditioning matrix set there are two preconditioning matrixs are orthogonal, for example, first object pre-processes Matrix is orthogonal with the first preconditioning matrix, in this way, the first transport layer is pre-processed when using first object preconditioning matrix, The second transport layer is pre-processed using the first preconditioning matrix, it can be to avoid between the first transport layer and the second transport layer Interference.
Optionally, if the transmitting terminal is first terminal equipment, modulation symbol can be mapped in by first terminal equipment In one or more transport layers, if modulation symbol is mapped in multiple transport layers by first terminal equipment, multiple transport layers can It, can be different to avoid first terminal equipment to be pre-processed using preconditioning matrix multiple and different in preconditioning matrix set Symbol-interference between transport layer；Similarly, the first transmitting terminal can be first terminal equipment, and the second transmitting terminal can be second Terminal device, then modulation symbol can be mapped in a transport layer by first terminal equipment, and first terminal equipment uses first For preconditioning matrix to the modulation symbol in the transport layer, modulation symbol can be mapped in an other biography by second terminal equipment On defeated layer, second terminal equipment using the second preconditioning matrix to the modulation symbol in the transport layer, the first preconditioning matrix and Second preconditioning matrix is different, in this way, the transmission of the transport layer and second terminal equipment of different first terminal equipment can be reduced The interference of layer.
Optionally, in receiving end, if the data of the different transport layers of a terminal device or different terminal equipment The data of transport layer can be distinguished well by spatial domain, i.e., the interference between different transport layers is smaller, to each biography Also identical preconditioning matrix can be used when defeated layer is pre-processed.That is the division of spatial domain can reduce different transport layers Interference, therefore, different transport layers can use identical preconditioning matrix, and the embodiment of the present application is for no restriction.
