[0045] MIMO is a key wireless technology that splits a single transmission signal into multiple streams, which are then distributed to multiple receivers. It can significantly improve the transmission distance, security level, and throughput of wireless network signal transmission. MIMO has the following advantages:

[0046] 1. Wide coverage. MIMO can be applied to a variety of communication methods, such as wireless broadband, WiFi, Bluetooth, LTE (Long Term Evolution), and NR, and can cover a very wide range of coverage;

[0047] Second, low power consumption. MIMO is placed on a vertical, smooth reflective surface, allowing signal traffic to be forwarded to almost any area, thus more effectively utilizing transmission power and saving energy.

[0048] 3. Increased transmission distance. The wall-penetrating effect of the MIMO system significantly increases the transmission distance, enabling it to more effectively overcome anti-interference barriers;

[0049] 4. Enhanced security: MIMO systems use multi-path transmission to increase the space through which signals can pass, thus reducing external interference.

[0050] 5. Improved network capacity. MIMO can provide more channels and more beams to increase capacity while providing relatively stable reception.

[0051] 6. Reduce costs: MIMO systems utilize their multi-path transmission characteristics to share signal sources, thereby minimizing costs and reducing operators' operating costs.

[0052] MIMO technology, with its new ideas and complete system as a breakthrough, has been applied in various fields, greatly improving transmission efficiency and continuously promoting the advancement of wireless technology.

[0053] MU-MIMO refers to a wireless communication system in which a single base station serves multiple mobile terminals simultaneously and on the same frequency. Base stations fully utilize the antenna's spatial resources to communicate with multiple users simultaneously and on the same frequency. MU-MIMO utilizes multiple antennas at both the transmitter and receiver to improve spectrum efficiency and is a key enabling technology in 5G.

[0054] MU-MIMO allows base stations to transmit data to multiple terminals concurrently, making data transmission in wireless networks more efficient and reducing the waiting time of terminals in terms of timing. Therefore, it can better meet the needs of video, audio and other high-traffic, low-latency applications.

[0055] 5G NR base stations generally adopt massive MIMO in the 3.5 GHz and higher frequency bands. Multi-user MIMO can transmit downlink data to multiple users simultaneously and on the same frequency (downlink is the process of terminal receiving data), thereby improving network throughput and single-user rate experience. It is a widely used transmission method in NR. However, in the downlink MU-MIMO scenario, there will be mutual interference between users.

[0056] In related technologies, strong interference can generally only be avoided by base station-side user scheduling. However, since base station scheduling needs to take into account factors such as fairness, traffic demand, and the actual location of users, this solution still cannot avoid the adverse impact on downlink reception reliability. Alternatively, strong interference in MU-MIMO scenarios can be avoided by introducing an interference processing receiver. However, simulation experiments show that under this solution, terminals are still affected by interference, resulting in the inability to achieve the expected throughput at the desired SNR (Signal to Noise Ratio).

[0057] In the embodiments of the present disclosure, a method for interference processing in a multi-user multiple-input multiple-output scenario is first provided, which at least to some extent overcomes the defect in related technologies that inter-user interference in MU-MIMO scenarios cannot be avoided.

[0058] Figure 1 A flow chart of an interference handling method in a multi-user multi-input multi-output scenario according to an embodiment of the present disclosure is shown. The execution subject of the interference handling method in the multi-user multi-input multi-output scenario can be any target terminal accessing the base station.

[0059] refer to Figure 1 According to an embodiment of the present disclosure, a method for handling interference in a multi-user multiple-input multiple-output scenario includes the following steps:

[0060] Step S110: In response to receiving the capability query message sent by the base station, the target terminal reports to the base station the interference handling capability of the target terminal for the multi-user multiple-input multiple-output scenario;

[0061] Step S120: Receive auxiliary information sent by the base station, and perform interference processing based on the auxiliary information.

[0062] exist Figure 1In the technical solutions provided by the illustrated embodiments, on the one hand, the present disclosure can directly send auxiliary information to the target terminal (with interference processing capabilities for MU-MIMO scenarios) through the base station, so that the target terminal does not need to obtain the above information through multiple complex methods, and can quickly perform inter-user interference processing based on the above auxiliary information, thereby saving terminal energy consumption and improving the terminal's interference processing speed. On the other hand, since the terminal can perform inter-user interference processing based on the above auxiliary information, the interference impact on downlink data reception in the MU-MIMO scenario can be reduced, and the reliability of downlink data reception can be greatly improved.

[0063] The following Figure 1 The specific implementation process of each step is described in detail:

[0064] It should be noted that before step S110, the base station side may first send a capability query message (UE Capability Enquiry message) to the N terminals accessing the base station. The function of the capability query message is to query whether the above N terminals have interference processing capabilities in the MU-MIMO scenario.

[0065] For any one of the N terminals mentioned above, the remaining N-1 terminals can be referred to as its spatial division multiplexing terminals. Multiplexing is a method of combining several independent signals into a composite signal that can be transmitted simultaneously on the same channel. For example, the frequency spectrum of a transmitted voice signal typically falls between 300 and 3400 Hz. To enable transmission of several such signals on the same channel, their spectra can be modulated into different frequency bands, combined to prevent mutual interference and separated at the receiving end. Spatial division multiplexing, on the other hand, allows the same frequency band to be reused in different locations.

[0066] After the base station sends a capability query message to the N terminals connected to the base station, step S110 may be entered. In response to receiving the capability query message sent by the base station, the terminal reports to the base station the interference handling capability of the terminal for the multi-user multiple-input multiple-output scenario.

[0067] In this step, after each of the N terminals receives a capability query message sent by the base station, the M target terminals deployed with interference processing receivers to support inter-user interference processing in the MU-MIMO scenario can report their interference processing capabilities for the MU-MIMO scenario to the base station. The interference processing receiver receives analog or digital amplitude modulation (AM), frequency modulation (FM), or digital broadcast signal (DBS) signals from radio frequencies and converts them into audible, visible, or digital information processing signals through components such as radio frequency amplifiers, mixers, intermediate frequency amplifiers, and detectors. During this process, the interference processing receiver can suppress all unwanted noise, including other signals, and does not add any noise or interference to the desired signal. Regardless of the form or format of the signal, it can be converted to meet the characteristics required by the signal processor's detection circuit before being sent to the intelligent user interface.

[0068] Specifically, each of the M target terminals may report any one or a combination of the following capabilities to the base station based on its actual capabilities:

[0069] Capability 1: Interference processing algorithms supported by the target terminal. Exemplarily, the interference processing algorithms supported by the target terminal may include any one or more of the following algorithms, which may be reported based on actual conditions and are not specifically limited in this disclosure.

[0070] Exemplarily, the above-mentioned interference processing algorithm can be a minimum mean square error interference suppression combining algorithm (Minimum Mean Squared Error-Interference Rejection Combining, MMSE-IRC algorithm), an enhanced minimum mean square error interference suppression combining algorithm (Enhanced Minimum Mean Squared Error-Interference Rejection Combining, E-MMSE-IRC algorithm), a low-complexity maximum likelihood algorithm (Reduced-MaximumLikelihood, R-ML algorithm), etc.

[0071] Capability 2: The target terminal supports interference handling based on network assistance information, that is, the target terminal can handle inter-user interference based on network assistance information. The above network assistance information can include any one or more of the following six items of information:

[0072] Information 1: The modulation order of the target terminal's spatial division multiplexing terminal. Modulation is the process of superimposing a low-frequency signal to be transmitted onto a high-frequency oscillator signal. The modulation order represents the number of bits transmitted per symbol and directly affects the reliability and transmission rate of the communication system.

[0073] Information 2: DMRS (Demodulation Reference Signal) configuration information for the target terminal's spatial division multiplexing (SDM) terminal. DMRS is used in 5G NR for demodulation of the PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), and PDSCH (Physical Downlink Shared Channel). DMRS, or DM-RS, is specific to a particular UE (User Equipment) and is used to estimate the radio channel. The base station can beamform the DMRS, retaining it within scheduled resources and transmitting it only when necessary for downloading or uploading data. Additionally, multiple orthogonal DMRS can be allocated to support MIMO transmission. The network provides DMRS information to users as early as possible to meet the initial decoding requirements of low-latency applications, but it also occasionally provides this information for low-speed scenarios with minimal channel variations. In high-mobility scenarios to track rapidly changing channels, the transmission rate of the DMRS signal (called "additional DMRS") may be increased.

[0074] Exemplarily, the DMRS configuration information may include any one or more of the following: ① The configuration type (DMRS-Type) of the demodulation reference signal (DMRS), which determines the RE mapping density of the DMRS in the frequency domain. 3GPP specifies two configuration types for PDSCH DMRS: type 1 and type 2. For type 1, DMRS REs are distributed at intervals in the frequency domain of a certain symbol, with a density of 50%; while for type 2, DMRS REs are connected together every two REs, with an interval of 4 REs, with a density of 33.3%. ② The additional position (DMRS-AdditionalPosition) of the demodulation reference signal (DMRS). DMRS signals can be divided into front-loaded DMRS and post-loaded DMRS based on their position. Post-loaded DMRS is the additional DMRS mentioned here. Front-loaded DMRS is mandatory, while post-loaded DMRS can be optional. Post-loaded DMRS is generally used in medium- and high-speed mobile scenarios. By inserting more DMRS pilot symbols in the scheduling time slot, the estimation accuracy of the time-varying channel is improved. A maximum of three additional positions can be configured within a time slot. ③ Maximum OFDM symbol length (maxLength) of the demodulation reference signal (DMRS), the maximum number of symbols occupied by the pre-DMRS. If this parameter is not configured in the RRC message, the default value is len1, meaning the pre-DMRS occupies only one symbol. A value of len2 indicates that the pre-DMRS can occupy a maximum of two symbols, with one symbol in some time slots and two symbols in others. The actual number of symbols occupied is dynamically determined by the "Antenna port(s)" field in DCI 1-1. The design of two symbols is primarily to support more antenna ports.

[0075] Information 3: Configuration information of the CSI-RS (Channel State Information Reference Signal) of the spatial division multiplexing terminal of the target terminal. It is a type of reference signal used for downlink channel state information measurement in NR, which facilitates the base station to take channel quality into consideration during downlink scheduling. Exemplarily, the configuration information may include resource mapping configuration, such as: the power offset of CSI-RS relative to PDSCH or SS, the scrambling code ID of CSI-RS relative to PDSCH or SS; it may also include period and offset configuration, as well as QCL (QCL can be used to support the reception of PDSCH and PDCCH on the UE side) configuration and other information, which can be set according to actual conditions, and this disclosure does not specifically limit this.

[0076] Information 4: Configuration information of the precoding resource block group PRG of the spatial division multiplexing terminal of the target terminal. The configuration information of the PRG is determined by the BWP (Bandwidth Part) starting point and PRB bundling size configured on the base station side. In 5G NR, the system can configure the PRBbundling size (i.e., the number of consecutive resource blocks P′ in the frequency domain) for the terminal. BWP.i ), P′ BWP.i It can be equal to a value in {2, 4, wideband}. If P′ BWP.i If P′ is determined to be 'wideband', the UE does not expect to be scheduled with non-contiguous PRBs and the UE may assume that the same precoding is used for its allocated resources. BWP.i is determined to be a value of 2 or 4, and PRGs uses P′ to represent the bandwidth of the i-th part. BWP.i Divided into continuous PRBs, the number of continuous PRBs in each PRG can be one or more, and the size of the first PRG is given by Decide if Then the last PRG is Otherwise it is P′ BWP.i The UE may assume that any downlink consecutive PRBs in each PRG are assigned the same precoding.

[0077] Information 5: Time domain resource scheduling information for the target terminal's spatial division multiplexing terminal. Time domain resources may include the sampling period, frame structure, basic parameter set of the OFDM (Orthogonal Frequency Division Multiplexing) system (e.g., subcarrier spacing, symbol length, CP length), CP, number of OFDM symbols, etc., which can be set based on actual conditions and are not specifically limited in this disclosure.

[0078] Information 6: Frequency domain resource scheduling information of the spatial division multiplexing terminal of the target terminal. Among them, frequency domain resources may include RE (Resource Element, the smallest granularity resource of the physical layer, 1 subcarrier in the frequency domain, 1 OFDM symbol in the time domain), RB (Resource Block, the basic frequency domain scheduling unit for data channel resource allocation, 12 subcarriers in the frequency domain, no time domain defined), RG (Resource Grid, physical layer resource group, the number of RB resources available within the transmission bandwidth in the frequency domain, NRB in the time domain), etc., which can be set according to actual conditions and are not specifically limited in this disclosure.

[0079] Capability 3: The target terminal supports interference handling without network assistance information. That is, even if one or more auxiliary messages sent by the base station do not contain network assistance information, the target terminal can still perform inter-user interference handling.

[0080] Capability 4: The target terminal supports inter-user interference processing when the network configuration does not conform to the default network configuration. That is, even when the network configuration does not conform to the default network configuration, the target terminal can still perform inter-user interference processing.

[0081] It should be noted that the above default network configuration may include any one or more of the following 13 default configurations:

[0082] Default configuration 1: The target terminal and its spatial division multiplexing terminal have the same demodulation reference signal DMRS configuration. The demodulation reference signal DMRS configuration can refer to the relevant explanation of the above information 2 and will not be repeated here. In addition, it can also be the same sequence scrambling ID (scrambling ID) configured with the target terminal and its spatial division multiplexing terminal, or the same n_SCID configured with the target terminal and its spatial division multiplexing terminal. It can be set according to actual conditions and is not specifically limited in this disclosure.

[0083] Default Configuration 2: The target terminal and its spatial division multiplexing terminal are configured with the same MCS Table (Modulation and Coding Scheme Table). Modulation and coding configuration in 5G NR is implemented through MCS (Modulation and Coding Scheme) index values. MCS forms a rate table with the factors affecting the communication rate as columns and MCS indexes as rows. Therefore, each MCS index actually corresponds to the physical transmission rate under a set of parameters.

[0084] Default configuration 3: The target terminal and its spatial division multiplexing terminal are configured with the same PRG (precoding resource block group). The configuration information of this PRG is determined by the BWP (Bandwidth Part) starting point and PRB bundling size configured on the base station side. In 5G NR, the system can configure the PRB bundling size (i.e., the number of consecutive resource blocks P′ in the frequency domain) for the terminal. BWP.i ), P′ BWP.i It can be equal to a value in {2, 4, wideband}. If P′ BWP.iIf P′ is determined to be 'wideband', the UE does not expect to be scheduled with non-contiguous PRBs and the UE may assume that the same precoding is used for its allocated resources. BWP.i is determined to be a value of 2 or 4, and PRGs uses P′ to represent the bandwidth of the i-th part. BWP.i Divided into continuous PRBs, the number of continuous PRBs in each PRG can be one or more, and the size of the first PRG is given by Decide if Then the last PRG is Otherwise it is P′ BWP.i The UE may assume that any downlink consecutive PRBs in each PRG are assigned the same precoding.

[0085] Default configuration 4: The target terminal and its spatial division multiplexing terminal are configured with the same PRB bundling size (physical resource block bundling size). Among them, 12 subcarriers in the frequency domain and 7 symbols in the time domain can constitute a physical resource block PRB. PRB is the smallest multi-user multiplexing unit of wireless resources. The PRB bundling size is used to instruct the terminal to bundle a certain number of physical resource blocks together into a physical resource block bundle (PRB bundle). In this way, when the same precoder is applied, channels across different RBs in the frequency domain can be regarded as continuous.

[0086] Default configuration 5: On each PRG (precoding resource block group) of the target terminal, the resource allocation of the target terminal and its spatial division multiplexing terminal is the same. Exemplarily, the resource may refer to a physical resource block (PRB) or a resource element (RE).

[0087] Default configuration 6: The target terminal and its spatial division multiplexing terminal have the same signal power ratio (also known as DMRS energy enhancement) configuration. The above-mentioned signal power ratio refers to the ratio between the power of each resource unit RE of the physical downlink shared channel PDSCH and the power of each resource unit RE of the demodulation reference signal DMRS. It should be noted that when the number of DMRS code division multiplexing CDM groups of the target terminal and its spatial division multiplexing terminal is the same, their signal power ratios must be the same.

[0088] Default configuration 7: The target terminal and its spatial division multiplexing terminal have the same downlink reference signal configuration, wherein the downlink reference signal includes any one or more of the following: PT-RS (Phase-tracking reference signals, used for phase noise estimation), CSI-RS (Channel State Information Reference Signal, a type of reference signal used for downlink channel state information measurement in NR, which facilitates the base station to take channel quality into account during downlink scheduling), and tracking reference signal TRS (Tracking Reference Signal).

[0089] Default configuration 8: The target terminal and its spatial division multiplexing terminal are configured with the same PDCCH (Physical Downlink Control Channel, downlink control channel, carrying scheduling and other control information) time domain resources. For example, the time domain resources can be a control channel element CCE (a PDCCH consists of one or more CCEs, and the number of CCEs contained in the PDCCH is called aggregation degree), a control resource set CORESET, etc., which can be set according to actual conditions. This disclosure does not make any special restrictions on this.

[0090] Default Configuration 9: The target terminal and its spatially multiplexed terminals use full-slot transmission for the downlink data channel (PDSCH). A slot is the smallest channel resource divided by time in time slicing technology and is the unit of a frame. Full-slot transmission means that all OFDM symbols in the slot, except those allocated for the PDCCH, are allocated to the target terminal and its spatially multiplexed terminals for PDSCH transmission.

[0091] Default configuration 10: The number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X, where X is an integer greater than or equal to 1. The number of data layers refers to the number of data symbols sent or received by the same terminal on the same time-frequency resources, also known as the number of data streams or spatial streams.

[0092] Default configuration 11: The number of spatial division multiplexing terminals of the target terminal is less than or equal to Y, where Y is an integer greater than or equal to 1.

[0093] Default configuration 12: On each physical resource block PRB or each precoding resource block group (PRG) of the target terminal, the target terminal and its spatial division multiplexing terminal are scheduled with the same modulation order.

[0094] Default configuration 13: the target terminal and its spatial division multiplexing terminal are scheduled with the same modulation order.

[0095] Capability 5: The number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X, where X is an integer greater than or equal to 1. This capability may include any of the following situations: in each physical resource block (PRB), the number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X; in each precoding resource block group (PRG), the number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X; in the entire bandwidth of the target terminal (bandwidth refers to the difference between the upper and lower layer frequencies in a continuous frequency band, which is usually measured in Hertz), the number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X.

[0096] Capability 6: The number of spatially multiplexed terminals of the target terminal is less than or equal to Y (Y is an integer greater than or equal to 1). This capability may include any of the following situations: in each physical resource block (PRB), the number of spatially multiplexed terminals of the target terminal is less than or equal to Y; or, in each precoding resource block group (PRG), the number of spatially multiplexed terminals of the target terminal is less than or equal to Y; or, in the entire bandwidth of the target terminal (bandwidth refers to the difference between the upper and lower layer frequencies in a continuous frequency band, which is usually measured in Hertz), the number of spatially multiplexed terminals of the target terminal is less than or equal to Y.

[0097] Capability 7: Demodulation Reference Signal (DMRS) configurations supported by the target terminal. As explained in the above steps, the DMRS configurations supported by the target terminal may include any one or more of the following: DMRS configuration type; DMRS additional location; and DMRS maximum OFDM symbol length. These details are omitted here.

[0098] After the above-mentioned M target terminals report the interference processing capability for the MU-MIMO scenario to the base station, the base station can send auxiliary information to K target terminals among the above-mentioned M target terminals, so that each of the above-mentioned K target terminals can execute the following step S120, receive the auxiliary information sent by the base station, and perform interference processing based on the auxiliary information.

[0099] In this step, each of the K target terminals may receive auxiliary information sent by the base station and perform inter-user interference processing based on the auxiliary information.

[0100] In an optional implementation, the auxiliary information sent by the base station may include indication information sent by the base station through RRC (Radio Resource Control, which refers to the management, control, and scheduling of radio resources through certain policies and means, while meeting quality of service requirements, making the best possible use of limited wireless network resources, ensuring that the planned coverage area is reached, and maximizing service capacity and resource utilization) and / or media access control (MAC) control element (CE) information. This indication information may be used to indicate whether the current network configuration of the target terminal complies with the default network configuration, or the indication information may be used to indicate that at least one current network configuration of the target terminal does not comply with the default network configuration. Thus, after receiving the multiplexing terminal information, the target terminal may perform inter-user interference processing based on the multiplexing terminal information.

[0101] As explained above, the default network configuration may include any one or more of the following:

[0102] Default configuration 1: The target terminal and its spatial division multiplexing terminal have the same demodulation reference signal DMRS configuration. The demodulation reference signal DMRS configuration can refer to the relevant explanation of the above information 2 and will not be repeated here. In addition, it can also be the same sequence scrambling ID (scrambling ID) configured with the target terminal and its spatial division multiplexing terminal, or the same n_SCID configured with the target terminal and its spatial division multiplexing terminal. It can be set according to actual conditions and is not specifically limited in this disclosure.

[0103] Default Configuration 2: The target terminal and its spatial division multiplexing (SDM) terminal are configured with the same MCS table (Modulation and Coding Scheme Table). In LTE, rate configuration is achieved through MCS (Modulation and Coding Scheme) index values. MCS forms a rate table with the factors affecting the communication rate as columns and MCS indexes as rows. Therefore, each MCS index corresponds to the physical transmission rate under a set of parameters.

[0104] Default configuration 3: The target terminal and its spatial division multiplexing terminal are configured with the same PRG (precoding resource block group). The configuration information of this PRG is determined by the BWP (Bandwidth Part) starting point and PRB bundling size configured on the base station side. In 5G NR, the system can configure the PRB bundling size (i.e., the number of consecutive resource blocks P′ in the frequency domain) for the terminal. BWP.i), P′ BWP.i It can be equal to a value in {2, 4, wideband}. If P′ BWP.i If P is determined to be 'wideband', the UE does not expect to be scheduled with non-contiguous PRBs and the UE may assume that the same precoding is used for its allocated resources. V ' WP.i is determined to be a value of 2 or 4, and PRGs uses P′ to represent the bandwidth of the i-th part. BWP.i Divided into continuous PRBs, the number of continuous PRBs in each PRG can be one or more, and the size of the first PRG is given by Decide if Then the last PRG is Otherwise it is P′ BWP.i The UE may assume that any downlink consecutive PRBs in each PRG are assigned the same precoding.

[0105] Default configuration 4: The target terminal and its spatial division multiplexing terminal are configured with the same PRB bundling size (physical resource block bundling size). Among them, 12 subcarriers in the frequency domain and 7 symbols in the time domain can constitute a physical resource block PRB. PRB is the smallest multi-user multiplexing unit of wireless resources. The PRB bundling size is used to instruct the terminal to bundle a certain number of physical resource blocks together into a physical resource block bundle (PRB bundle). In this way, when the same precoder is applied, channels across different RBs in the frequency domain can be regarded as continuous.

[0106] Default configuration 5: On each PRG (precoding resource block group) of the target terminal, the resource allocation of the target terminal and its spatial division multiplexing terminal is the same. Exemplarily, the resource may refer to a physical resource block (PRB) or a resource element (RE).

[0107] Default configuration 6: The target terminal and its spatial division multiplexing terminal have the same signal power ratio (also known as DMRS energy enhancement) configuration. The above-mentioned signal power ratio refers to the ratio between the power of each resource unit RE of the physical downlink shared channel PDSCH and the power of each resource unit RE of the demodulation reference signal DMRS. It should be noted that when the number of DMRS code division multiplexing CDM groups of the target terminal and its spatial division multiplexing terminal is the same, their signal power ratios must be the same.

[0108] Default configuration 7: The target terminal and its spatial division multiplexing terminal have the same downlink reference signal configuration, wherein the downlink reference signal includes any one or more of the following: PT-RS (Phase-tracking reference signals, used for phase noise estimation), CSI-RS (Channel State Information Reference Signal, a type of reference signal used for downlink channel state information measurement in NR, which facilitates the base station to take channel quality into account during downlink scheduling), and tracking reference signal TRS (Tracking Reference Signal).

[0109] Default configuration 8: The target terminal and its spatial division multiplexing terminal are configured with the same PDCCH (Physical Downlink Control Channel, downlink control channel, carrying scheduling and other control information) time domain resources. For example, the time domain resources can be a control channel element CCE (a PDCCH consists of one or more CCEs, and the number of CCEs contained in the PDCCH is called aggregation degree), a control resource set CORESET, etc., which can be set according to actual conditions. This disclosure does not make any special restrictions on this.

[0110] Default Configuration 9: The target terminal and its spatially multiplexed terminals both use full-slot transmission for the downlink data channel PDSCH. A slot is the smallest channel resource divided by time in time slicing technology and is the unit of a frame. Full-slot transmission means that all OFDM symbols in a slot, except those allocated for the PDCCH, are allocated to the target terminal and its spatially multiplexed terminals for PDSCH transmission.

[0111] Default configuration 10: The number of data layers of the spatial division multiplexing terminal of the target terminal is less than or equal to X, where X is an integer greater than or equal to 1. The number of data layers refers to the number of data symbols sent or received by the same terminal on the same time-frequency resources, also known as the number of data streams or spatial streams.

[0112] Default configuration 11: The number of spatial division multiplexing terminals of the target terminal is less than or equal to Y, where Y is an integer greater than or equal to 1.

[0113] Default configuration 12: On each physical resource block PRB or each precoding resource block group (PRG) of the target terminal, the target terminal and its spatial division multiplexing terminal are scheduled with the same modulation order.

[0114] Default configuration 13: the target terminal and its spatial division multiplexing terminal are scheduled with the same modulation order.

[0115] When the above-mentioned default network configuration includes multiple default configurations, and the indication information is used to indicate whether the current network configuration of the target terminal complies with the default network configuration, in an optional embodiment, the above-mentioned indication information can be set as an R-bit (BIT, a unit of measurement of information amount, which is the smallest unit of information amount) indication information, and the R-bit indication information is used to indicate whether the current network configuration of the target terminal complies with the multiple default configurations. For example, assuming that the above-mentioned default network configuration includes three default configurations (exemplarily, they can be default configuration 1, default configuration 2, and default configuration 3), and R is 3 bits, then when the indication information is "001", it can be determined that the current network configuration of the target terminal does not comply with the above-mentioned default configuration 1, does not comply with the above-mentioned default configuration 2, and complies with the above-mentioned default configuration 3. Therefore, only one indication information can be used to inform the target terminal whether the current network configuration complies with multiple default configurations. In another optional embodiment, the above-mentioned indication information can be set as multiple R-bit indication information. For example, the above-mentioned default network configuration still includes 3 default configurations (exemplarily, it can be default configuration 1, default configuration 2 and default configuration 3), and R is 1 bit. The base station can send 3 indication messages to the target terminal, each indication message corresponds to a default configuration and has a length of 1 bit. Therefore, when the first indication message is "0", it can be determined that the current network configuration of the target terminal does not comply with the above-mentioned default configuration 1. When the second indication message is "0", it can be determined that the current network configuration of the target terminal does not comply with the above-mentioned default configuration 2. When the third indication message is "1", it can be determined that the current network configuration of the target terminal complies with the above-mentioned default configuration 3.

[0116] When the default network configuration includes multiple default configurations, and the indication information is used to indicate that at least one of the target terminal's current network configurations does not comply with the default network configurations, in an optional embodiment, the indication information may be set as a piece of R-bit (BIT, the smallest unit of information) indication information, where the R-bit indication information is used to indicate that the target terminal's current network configuration does not comply with the corresponding at least one default configuration. For example, still assuming that the default network configuration includes three default configurations (illustratively, default configuration 1, default configuration 2, and default configuration 3), and R is 2 bits, then when the indication information is "12," it can be determined that the target terminal's current network configuration does not comply with default configuration 1 and default configuration 2 among the multiple default configurations, while the target terminal's current network configuration complies with default configuration 3 among the multiple default configurations. In another optional embodiment, the indication information may be set as multiple pieces of R-bit indication information, each piece of R-bit indication information is used to indicate that the target terminal's current network configuration does not comply with the corresponding at least one default configuration. For example, the above-mentioned default network configuration still includes 3 default configurations (exemplarily, it can be default configuration 1, default configuration 2 and default configuration 3), and R is 1 bit. Thus, the base station can send two indication messages to the target terminal, the first indication message corresponds to default configuration 1 and default configuration 2, and the second indication message corresponds to default configuration 3. Each indication message is 1 bit. Therefore, when the first indication message is "0" and the second indication message is not received, it can be determined that the current network configuration of the target terminal does not comply with at least one of the above-mentioned default configuration 1 and the above-mentioned default configuration 2, and the current network configuration of the target terminal complies with default configuration 3.

[0117] In another optional embodiment, the auxiliary information sent by the base station includes the multiplexing terminal information sent by the base station through the radio resource control RRC and / or the media access control MAC control element CE information, so that after receiving the above-mentioned multiplexing terminal information, the target terminal can perform inter-user interference processing based on the multiplexing terminal information.

[0118] Among them, the above-mentioned multiplexing terminal information may include any one or more of the following information of the spatial division multiplexing terminal of each target terminal: ① configuration information of the demodulation reference signal DMRS of the spatial division multiplexing terminal and / or whether the spatial division multiplexing terminal of the target terminal currently exists; ② modulation and coding strategy table information of the spatial division multiplexing terminal; ③ configuration information of the downlink reference signal of the spatial division multiplexing terminal. For example, referring to the above-mentioned relevant explanations, the downlink reference signal includes any one or more of the following: PT-RS (Phase-tracking reference signals, phase tracking reference signals, used for phase noise estimation), CSI-RS (Channel State Information Reference Signal, a type of reference signal used for downlink channel state information measurement in NR, which facilitates the base station to take channel quality into consideration during downlink scheduling), tracking reference signal TRS (Tracking Reference Signal Signal, tracking reference signal); ④ the configuration information of the control channel resources of the spatial division multiplexing terminal, which can be, for example, the starting ODFM symbol of the control channel and / or the ODFM symbol length of the control channel; ⑤ the scheduling information of the spatial division multiplexing terminal and the allocation information of the current time-frequency resources, such as: the number of spatial division multiplexing terminals, the time domain resource allocation information of one or more spatial division multiplexing terminals, and the frequency domain resource allocation information of one or more spatial division multiplexing terminals; ⑥ the allocation information of the demodulation reference signal DMRS port of the spatial division multiplexing terminal, which can be, for example, the DMRS port number allocated through the antenna port field in the DCI.

[0119] In another optional implementation, the auxiliary information sent by the base station also includes multiplexed terminal information sent by the base station via DCI (Downlink Control Information, which carries downlink control information for one or more cells with a single RNTI and provides the UE with physical layer resource allocation, power control commands, uplink and downlink HARQ information, and other information. DCI is transmitted via the PDCCH with a 24-bit CRC). Thus, after receiving the multiplexed terminal information, the target terminal can perform inter-user interference processing based on the multiplexed terminal information.

[0120] The above-mentioned multiplexing terminal information may include any one or more of the following information of the spatial division multiplexing terminal of the target terminal: ① the number of spatial division multiplexing terminals of the target terminal and / or whether a spatial division multiplexing terminal of the target terminal currently exists; ② the modulation order of the spatial division multiplexing terminal; ③ the number of data layers occupied by the spatial division multiplexing terminal; ④ the configuration information of the downlink reference signal of the spatial division multiplexing terminal. ⑤ the current time-frequency resource allocation information of the spatial division multiplexing terminal, for example: the number of spatial division multiplexing terminals, the time domain resource allocation information of one or more spatial division multiplexing terminals, the frequency domain resource allocation information of one or more spatial division multiplexing terminals; ⑥ the allocation information of the demodulation reference signal DMRS port of the spatial division multiplexing terminal, which can be, for example, the DMRS port number allocated through the antenna port field in the DCI.

[0121] Based on the above technical solution, on the one hand, the present disclosure can directly send auxiliary information to the target terminal (with interference processing capabilities for MU-MIMO scenarios) through the base station, so that the target terminal does not need to obtain the above information by itself through multiple complex methods, and can quickly perform inter-user interference processing based on the above auxiliary information, saving the energy consumption of the terminal and improving the interference processing speed of the terminal. On the other hand, since the terminal can perform inter-user interference processing based on the above auxiliary information, the interference effect on downlink data reception in the MU-MIMO scenario can be reduced, and the reliability of downlink data reception can be greatly improved.

[0122] The present disclosure also provides an interference processing device in a multi-user multiple-input multiple-output scenario, Figure 2 FIG. 1 is a schematic structural diagram of an interference processing device in a multi-user multiple-input multiple-output scenario in an exemplary embodiment of the present disclosure; FIG.

[0124] The interference processing module 220 is configured to receive the auxiliary information sent by the base station and perform interference processing based on the auxiliary information.
