Description

Interference process between a kind of nonopiate subscriber equipment and signaling methods and device

Technical field

The present invention relates to the non-orthogonal multiple of the communications field (NOMA, Non-orthogonalMultipleAccess) technology, particularly relate to the interference process between a kind of nonopiate subscriber equipment and signaling methods and device.

Background technology

nullMulti-user multiple-input and multiple-output (MU-MIMO，MultipleUserMultipleInputMultipleOutput) although technology is at Long Term Evolution (LTE，LongTermEvolution) version 8/9/10 has been defined for，But match what as far as possible orthogonal (namely disturbing as far as possible little) principle between MU user carried out owing to existing MU pairing definition is based on，This not only limit can the quantity of user of simultaneously MU pairing，And reality yet suffers between MU user interfering of residual and also limit MU-MIMO relative to single user multiple-input and multiple-output (SU-MIMO，SingleUserMultipleInputMultipleOutput) throughput gain.In order to increase pairing number of users or throughput of system further, the research about non-orthogonal multiple (NOMA, Non-orthogonalMultipleAccess) technology is applied and is given birth to.NOMA technology is normally based on successive interference cancellation (SIC, the SuccessiveInterferenceCancellation) technology of receiving terminal, it is not required that must be orthogonal between pairing user.

In LTE system, employing is that public reference signal (CRS, CommonReferenceSignal) carries out pilot measurement and data demodulation, and namely all users use CRS to carry out channel estimating.When adopting the precoding processing mode based on CRS, it is necessary to concrete pre-coding matrix (can also the be called precoding weights) information that transmitting terminal additional notifications receiving terminal data use when sending, the expense of pilot tone is bigger.It addition, in MU-MIMO system, owing to multiple terminals use identical CRS, it is impossible to realize the orthogonal of pilot tone, therefore, be unable to estimate interference.

At the Long Term Evolution (LTE-A strengthened, AdvancedLongTermEvolution) in system, in order to reduce pilot-frequency expense and improve channel estimation accuracy, pilot measurement and data demodulation function are separated, respectively define two class reference signals, i.e. demodulated reference signal (DMRS, DemodulationReferenceSignal) and channel state information reference signals (CSI-RS, ChannelStateInformationReferencedSignal).Wherein, CSI-RS is mainly used in channel measurement to obtain channel quality information (CQI, and feed back ChannelQualityInformation), so that base station side can utilize this information complete user scheduling and realize modulation coding mode (MCS, ModulationandCodingScheme) self-adjusted block, does not carry precoding information in the transmission of CSI-RS；And DMRS is mainly used in Physical Downlink Shared Channel (PDSCH, PhysicalDownlinkSharedChannel) and strengthen Physical Downlink Control Channel (ePDCCH, enhancedPhysicalDownlinkControlChannel) channel estimating is to complete the demodulation of data/control channel, and the transmission of DMRS carries the precoding information of corresponding PDSCH/ePDCCH.LTE and lte-a system can be divided into FDD (FDD according to the difference of up-downgoing duplex mode, and time division duplex (TDD FrequencyDivisionDuplex), TimeDivisionDuplex) system, the pattern of CSI-RS and the DMRS of FDD and TDD system can difference to some extent.

In LTE, in order to support the adjustment to different terminals PDSCH transmit power, introduce P_AAnd P_BTwo parameters are used for the ratio indicating the every Resource Unit power (EPRE, EnergyperResourceElement) of PDSCH with CRSEPRE.Due in LTE, support the powerboosting (power enhancing) to CRS, simultaneously in order to ensure each OFDM (OFDM, OrthogonalFrequencyDivisionMultiplexing) the transmit power concordance of symbol, in the OFDM symbol sending CRS, while CRS carries out powerboosting, PDSCH needs to reduce certain power, and then cause sending in the OFDM symbol of CRS and not sending in the OFDM symbol of CRS, EPRE corresponding for PDSCH there are differences.In order to distinguish this species diversity, define ρ respectively_ARepresent there is no the ratio of PDSCHEPRE and CRSEPRE, ρ in the OFDM symbol of CRS_BRepresenting exists in the OFDM symbol of CRS, the ratio of PDSCHEPRE and CRSEPRE, now P_B=ρ_B/ρ_A.Wherein, when PDSCH is based on 4 antenna transmission diversity transmission, ρ_A=δ_power-offset+P_A+10log₁₀(2), otherwise, ρ_A=δ_power-offset+P_A；Wherein, δ_power-offsetExcept the value under MU-MIMO transmission pattern is-3dB, under other scene, value is 0dB.Above-mentioned information all corresponds to the information between targeted customer and Serving cell on link.

How to set up a set of signaling mechanism well to support the application in systems in practice of NOMA technology, be the problem being presently required solution in NOMA technical research.

Fig. 5 illustrates the general flow figure of a kind of transmitting uplink data using NOMA technology based on the embodiment of the present invention.In Fig. 5, in the out-hole run stage, target UE sends up channel and measures pilot tone, for instance the detection reference signal (SRS, SoundingReferenceSignal) (shown in the S501 in Fig. 5) in LTE；The up channel link quality related information that pilot measurement arrives is measured, according to up channel, in base station, determine the information such as power distribution between data transmission block number and these data transmission blocks of interference elimination order (or the priority orders between base station) between the base station in the uplink receiving group of base stations of this target UE, uplink receiving group of base stations, up transmission, and inform target UE (shown in the S502 in Fig. 5).Target UE sends above-mentioned data transmission block as indicated respectively to each base station (shown in the S503 in Fig. 5) in uplink receiving group of base stations；Base station carries out interference elimination based on the related transmitting information of these data transmission blocks, then demodulates/decode target data transport block data (shown in the S504 in Fig. 5).Wherein, before carrying out interference elimination between base station, the configuration information that the different pieces of information transport block transmission that this target UE sends of communicating with each other between base station is relevant, for instance precedence information between the pilot configuration information of these data transmission blocks, power allocation information, MCS information, data transmission block information of number, data transmission block, target data transmission block identification information etc. at least one.

Such as, hypothetical target subscriber equipment has only allowed a pairing subscriber equipment, by high-level signaling define 4 kinds of power-division ratios respectively 1/1,1/2,1/4, > 1, then network side can pass through 2 bits dynamically control signaling to specific objective notification of user equipment its with pairing subscriber equipment power-division ratios, as shown in table 2 below:
