[0004] Multi-antenna technology has been widely adopted in various wireless communication technologies, including multiple-input-multiple-output (MIMO), joint transmission (JT), and high-frequency beamforming. To maximize the performance of multiple antennas, it is crucial for communication nodes to obtain accurate channel information. Currently, in the field of multi-antenna technology, channel state information reference signals (CSI-RS) can be used for channel measurement, channel prediction, codebook feedback, precoding, and other operations, enabling the network to dynamically adjust and optimize based on real-time channel conditions. However, terminals can typically only perform CSI-RS reception measurements based on relatively fixed configuration information on the network side, resulting in limited flexibility.

[0040] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0041] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be necessarily different.

[0042] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] To enhance the flexibility of channel state information reference signal configuration, the present disclosure provides a reference signal configuration method, comprising: obtaining reference signal configuration information, the reference signal configuration information including description information of X reference signals, where X is a positive integer; and transmitting the X reference signals based on the reference signal configuration information. In this manner, the description information of the X reference signals can be determined based on the actual wireless channel environment, enabling adaptive reference signal configuration based on the actual wireless channel environment.

[0044] The channel state information reference signal (CSI-RS) is an important component of mobile communication networks. It provides critical channel state information, provides a basis for dynamic adjustment and optimization of the network, and helps improve the efficiency and reliability of wireless communications.

[0045] CSI RS can be used for channel sounding and measuring wireless channel characteristics, including operations such as channel measurement, channel prediction, codebook feedback, and precoding. It plays a vital role in mobile communication networks, enabling dynamic adjustments and optimizations based on real-time channel conditions, thereby achieving more efficient and reliable wireless communications.

[0046] In some examples, a transmitting device can send a CSI RS to a receiving device at the physical layer using predefined time-frequency resources. These predefined time-frequency resources are time-frequency resources pre-allocated to the receiving device for measuring channel quality and providing feedback. Accordingly, after receiving the CSI RS, the receiving device can measure the channel, calculate feedback information, and send feedback information about the channel quality, such as channel quality, number of layers, and precoding, to the transmitting device. Furthermore, the transmitting device can optimize its transmission method based on the feedback information sent by the receiving device to improve channel transmission efficiency and reliability.

[0047] Furthermore, the design of CSI RS must consider multiple factors, such as signal power, sequence design, and allocation method, to ensure that sufficient reference information can be provided to support operations such as channel measurement, channel prediction, codebook feedback, and precoding. Furthermore, the design of CSI RS must also consider interference and coordination with other signals and channels to ensure the performance and stability of the entire wireless communication system.

[0048] The method provided by the embodiment of the present disclosure can be applied to various communication systems. For example, the communication system can be a long term evolution (LTE) system, a fifth generation (5G) communication system, a Wi-Fi system, a communication system related to the third generation partnership project (3GPP), a future evolutionary communication system (such as a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. The following describes the method provided by the embodiment of the present disclosure by taking the communication system 100 shown in Figure 1 as an example. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present disclosure.

[0049] FIG1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. As shown in FIG1 , the communication system 100 may include one or more network devices 11 and one or more terminal devices 12. The terminal device 12 may be communicatively connected to the one or more network devices 11.

[0050] In some embodiments, the network device 11 can be used to implement functions such as resource scheduling, wireless resource management, and wireless access control of terminal devices. For example, it can be an evolution nodeB (eNB), a next-generation base station (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access nodes. Depending on the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells (Macro cells), a micro base station for providing micro cells (Pico cells), and a femto base station for providing femto cells (Femto cells). With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0051] The terminal device 12 may also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. For example, the terminal device 12 may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality terminal, an augmented reality terminal, a wireless terminal used in industrial control, a wireless terminal used in unmanned driving, a wireless terminal used in remote surgery, a wireless terminal used in transportation safety, a wireless terminal used in smart cities, a wireless terminal used in smart homes, etc. The embodiments of the present disclosure do not limit the specific device form used by the terminal.

[0052] In some embodiments, during a communication process, a network device sends data to a terminal device, and the terminal device receives the data sent by the network device. Thus, the network device can be referred to as a transmitter. Accordingly, the terminal device can be referred to as a receiver. Alternatively, when a terminal device sends data to a network device, the network device can be referred to as a receiver. Accordingly, the terminal device can be referred to as a transmitter.

[0053] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices or nodes included in Figure 1 and the names of each device are not restricted. In addition to the functional nodes shown in Figure 1, the communication system may also include other nodes or devices, such as core network devices.

[0054] The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0055] The embodiments provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0056] As shown in FIG2 , the present disclosure provides a method for configuring a reference signal, which is applied to a transmitting device and includes the following steps:

[0057] S101: Acquire configuration information of a reference signal, where the configuration information of the reference signal includes description information of X reference signals.

[0058] In some embodiments, the X reference signals belong to a set of G reference signals, where G is an integer greater than or equal to 1.

[0059] In addition, the reference signals provided in the present disclosure include multiple types of reference signals, such as a channel state information reference signal, a demodulation reference signal (DMRS), a phase tracking reference signal (PTRS), a paging reference signal (SRS), etc.

[0060] In some embodiments, the description information includes at least one of the following:

[0061] Identification information of X reference signals;

[0062] Resource information of X reference signals;

[0063] Sequence information of X reference signals;

[0064] Power information of X reference signals;

[0065] Number of ports corresponding to X reference signals;

[0066] Relationship information between the ports corresponding to the X reference signals and other ports on the transmitting end;

[0067] relationship information between ports corresponding to different reference signals among the X reference signals;

[0068] Transmission priority information of all or part of the X reference signals;

[0069] Indication information of a feedback mode for determining feedback information based on the X reference signals;

[0070] Description of how the receiver processes all or part of the X reference signals;

[0071] Instruction information of selection rules for the receiving end to select a processing method;

[0072] Description of a selection rule for selecting a target reference signal from among X reference signals;

[0073] an indication of the maximum number of target reference signals;

[0074] Used to feed back indication information of the maximum data amount determined based on X reference signals.

[0075] The following describes in detail each item of description information of the X reference signals.

[0076] (1) Identification information of X reference signals

[0077] Among them, the identification information of the reference signal can be used to indicate information about parameters related to the reference signal, such as the channel state information reference signal, between the transmitting device and the receiving device, so as to facilitate the receiving device or the transmitting device to identify the relevant parameters of the information state information reference signal.

[0078] Therefore, the description information of the reference signal to be transmitted by the transmitting device may include the identification information of the reference signal. Since the reference signal configuration information includes the description information of X reference signals, the reference signal configuration information may include the identification information of X reference signals. In addition, the identification information may also be carried during the channel state information feedback process.

[0079] (2) Resource information of X reference signals

[0080] The resource information of the reference signal may include information describing the resource location of a received reference signal, such as a channel state information reference signal. For example, the resource location may be determined by a time slot location, an orthogonal frequency-division multiplexing (OFDM) symbol location, or a subcarrier location.

[0081] That is, the receiving end device may notify the receiving end device based on the resource information of a reference signal, such as a channel state information reference signal, to receive the channel state information reference signal at the resource location corresponding to the resource information. Furthermore, because the reference signal configuration information includes description information of X reference signals, the reference signal configuration information may also include resource information of the X reference signals.

[0082] In some embodiments, resources occupied by a reference signal at different ports are equal in size.

[0083] In some embodiments, the resource sizes occupied by a reference signal at different ports are unequal.

[0084] (3) Sequence information of X reference signals

[0085] The sequence information of the reference signal is used to describe the sequence corresponding to the reference signal, such as the channel state information reference signal. In addition, since the configuration information of the reference signal includes description information of X reference signals, the configuration information of the reference signal may include sequence information of X reference signals.

[0086] For example, the sequence information of the reference signal may include a sequence generation method for the sequence corresponding to the reference signal. The sequence generation methods for the sequence corresponding to the reference signal include a maximum length linear feedback shift register sequence (also known as an m-sequence), Gold Codes (also known as Gold sequences), a CHU sequence (Chu sequence), a Zadoff-Chu sequence (also known as a ZC sequence), a chirped pulse (also known as a CHIRP sequence), a method obtained by calculation and search according to specific criteria, a method of obtaining an output by linearly or nonlinearly processing a specific input, a method obtained based on processing of a portion of useful data bits, or other possible methods.

[0087] In some embodiments, the sequence information of the X reference signals satisfies at least one of the following:

[0088] The sequence generation method used by each of the X reference signals is the same;

[0089] Each reference signal in the X reference information uses a different sequence generation method;

[0090] Some of the reference signals in the X reference information use different sequence generation methods;

[0091] For each reference signal among the X reference signals, a sequence generation method used on multiple antenna ports transmitting the reference signal is the same;

[0092] For each reference signal among the X reference signals, a sequence generation method used on multiple antenna ports transmitting the reference signal is different;

[0093] For each reference signal among the X reference signals, different sequence generation modes are used on some antenna ports among the multiple antenna ports that transmit the reference signal.

[0094] In one example, among the X reference signals, at least one reference signal uses an m-sequence as its sequence generation method, at least one reference signal uses a Gold sequence as its sequence generation method, and at least one reference signal uses a ZC sequence as its sequence generation method.

[0095] In another example, for each reference signal among the X reference signals, among the multiple antenna ports that transmit the reference signal, the sequence generation method used on at least one antenna port is an m-sequence, the sequence generation method used on at least one antenna port is a Gold sequence, and the sequence generation method used on at least one antenna port is a ZC sequence.

[0096] In some embodiments, the sequence information of the reference signal may further include sequence length, sequence content, etc.

[0097] (4) Power information of X reference signals

[0098] The reference signal power information may include the transmit power of a reference signal, such as a channel state information reference signal. Furthermore, since the reference signal configuration information includes description information of X reference signals, the reference signal configuration information may include power information of the X reference signals.

[0099] In some embodiments, for the X reference signals, the transmit power of different reference signals, such as the channel state information reference signal, may be the same. Alternatively, the transmit power of different reference signals may be different. For example, in a distributed multi-antenna system, the transmit power of reference signals corresponding to nodes at different locations or of different types may be different. Furthermore, the transmit power value may be expressed in absolute or relative terms.

[0100] (5) Number of ports corresponding to X reference signals

[0101] The number of ports corresponding to the reference signal is the number of antenna ports that carry the reference signal, such as the channel state information reference signal. Furthermore, because the reference signal configuration information includes description information for X reference signals, the reference signal configuration information may include the number of ports corresponding to the X reference signals. For example, the number of ports corresponding to the reference signal may be 2, 4, 8, 16, 24, 32, 64, 128, 256, and so on.

[0102] In some embodiments, different reference signals in the X reference signals correspond to the same number of ports.

[0103] In some embodiments, different reference signals in the X reference signals correspond to different numbers of ports.

[0104] (6) Relationship information between the ports corresponding to the X reference signals and other ports on the transmitting end

[0105] In some embodiments, the relationship information between the ports corresponding to the X reference signals and other ports of the transmitting end includes: a mapping relationship between the ports corresponding to the X reference signals and other ports. For one of the X reference signals, the description information of the reference signal includes relationship information between an antenna port used to carry the reference signal and other antenna ports.

[0106] For example, assuming the reference signal is a channel state information reference signal (CSI) and the transmitting device is a large-scale multiple-input multiple-output (MIMO) base station. This Massive MIMO base station has 256 physical antennas, 64 of which form a CSI reference signal with 64 antenna ports. Therefore, the transmitting device needs to send the mapping relationship between these 64 physical antennas and all 256 physical antennas to the receiving device, as shown in Figure 3, where each box represents 16 antenna ports, and the black boxes represent the 64 antenna ports corresponding to the X CSI reference signals selected from the 256 antenna ports.

[0107] For another example, as shown in Figure 4, a distributed base station system has 10 nodes serving a receiving device, such as terminal 41. Based on the system's topology, the network can select five of these ten nodes to form a channel state information reference signal (CSI) with 32 antenna ports. Therefore, the transmitting device needs to send the topological relationship between the selected five nodes and all ten nodes to the receiving device.

[0108] (7) Relationship information between ports corresponding to different reference signals among the X reference signals

[0109] In some embodiments, the description information of the X reference signals may include relationship information between antenna ports corresponding to different reference signals, such as different channel state information references.

[0110] For example, the four antenna ports corresponding to the channel state information reference signal CSI RS-A include P0, P1, P2, and P3, and the four antenna ports corresponding to the channel state information reference signal CSI RS-B include P2, P3, P4, and P5. Thus, the relationship information can be used to illustrate that the two reference signals, the channel state information reference signal CSI RS-A and the channel state information reference signal CSI RS-B, have common antenna ports P2 and P3. For another example, the four antenna ports corresponding to the channel state information reference signal CSI RS-C include P0, P1, P2, and P3, and the four antenna ports corresponding to the channel state information reference signal CSI RS-D include P7, P8, P9, and P10. Thus, the relationship information can be used to illustrate the mapping relationship between the antenna ports of the two reference signals, the channel state information reference signal CSI RS-C and the channel state information reference signal CSI RS-D, that is, the mapping relationship between the eight antenna ports P0, P1, P2, and P3 and P7, P8, P9, and P10.

[0111] (8) Transmission priority information of all or part of the X reference signals

[0112] The reference signal transmission priority information is used to indicate the transmission priority rules between the reference signal, such as a channel state information reference signal, and other signals or channels. Furthermore, the reference signal configuration information may include transmission priority information for Y reference signals, where Y is less than or equal to X.

[0113] In some embodiments, among the X reference signals, there is overlap between the ports corresponding to at least two reference signals. Exemplarily, antenna ports between different channel state information reference signals may partially overlap.

[0114] In some embodiments, the time domain resources occupied by the X reference signals overlap with the time domain resources occupied by sending other signals.

[0115] For example, as shown in FIG5 , a reference signal such as a channel state information reference signal A and a physical downlink control channel (PDCCH) channel (or a physical downlink shared channel (PDSCH) channel, a synchronization signal, or other signals or channels) overlap in the time domain and use different subcarriers in the frequency domain, resulting in a transmission conflict. For example, the channel state information reference signal A and the PDCCH channel require the receiving device to use different spatial filtering reception methods. At this time, the transmission priority of the channel state information reference signal A and the PDCCH channel can be determined and indicated to the receiving device based on indicators such as actual load conditions and business service quality, thereby achieving dynamic adjustment of the transmission priority.

[0116] In some embodiments, frequency domain resources occupied by the X reference signals overlap with frequency domain resources occupied by other signals.

[0117] For example, as shown in Figure 6, a reference signal, such as the Channel State Information Reference Signal (CSI) B, and a PDCCH (or other signals or channels, such as a PDSCH or synchronization signal) use some of the same subcarriers in the frequency domain, as shown in the overlapping area in Figure 6. This indicates a transmission conflict. In this case, the transmission priority of the CSI Reference Signal (CSI) B and the PDCCH can be determined and indicated to the receiving device based on actual load conditions, service quality, and other indicators, thereby achieving dynamic adjustment of the transmission priority.

[0118] (9) Indication information of feedback mode based on X reference signals

[0119] Exemplarily, taking the reference signal as a channel state information reference signal, the indication information is used to indicate the feedback method of the channel state information (ie, the above-mentioned feedback information) generated by the receiving device, such as the terminal, based on the received channel state information reference signal.

[0120] In some embodiments, the feedback methods include independent feedback or joint feedback. For example, an independent feedback method may be used in which the receiving device independently compresses and encodes the channel state information generated for each channel state information reference signal. Another example is a joint feedback method in which the receiving device generates joint channel state information for multiple channel state information reference signals, including joint compression, joint encoding, and other joint feedback methods.

[0121] (10) Description of how the receiving end processes all or part of the X reference signals

[0122] The description of the receiving end's processing method for all or part of the X reference signals is used to describe the receiving end device's processing method or a set of processing methods for all or part of the received X reference signals, where the set of processing methods includes one or more processing methods. In some embodiments, at least one processing method includes a linear processing method and / or a nonlinear processing method. In one example, the set of processing methods may include both a linear processing method and a nonlinear processing method.

[0123] For example, a transmitting device sends four channel state information reference signals (CSI RS-A, CSI RS-B, CSI RS-C, and CSI RS-D) to a receiving device, and the transmitting device also sends indication information of processing methods for the four channel state information reference signals to the receiving device. For example, indication information for indicating a linear processing method for CSI RS-A, such as a linear minimum mean square error algorithm, Wiener filtering, or other linear processing methods; indication information for indicating a nonlinear processing method for CSI RS-B and CSI RS-C, such as an iterative algorithm, a neural network, or deep learning; and indication information for a pre-agreed processing method for CSI RS-D. Accordingly, the receiving device can perform channel measurement, channel estimation, channel prediction and other processing on the channel on the received channel state information reference signal CSI RS-A based on a linear method, perform channel measurement, channel estimation, channel prediction and other processing on the channels on the received channel state information reference signals CSI RS-B and CSI RS-C based on a nonlinear processing method, and perform channel measurement, channel estimation, channel prediction and other processing on the channel on the received channel state information reference signal CSI RS-D based on a pre-agreed processing method.

[0124] For another example, a transmitting device sends four channel state information reference signals (CSI RS-A, CSI RS-B, CSI RS-C, and CSI RS-D) to a receiving device, and the transmitting device also sends indication information of processing mode sets for the four channel state information reference signals to the receiving device. For example, the transmitting device may send indication information of a first processing mode set corresponding to the channel state information CSI RS-A, indication information of a second processing mode set corresponding to CSI RS-B, indication information of a third processing mode set corresponding to CSI RS-C, and indication information of a third processing mode set corresponding to CSI RS-D to the receiving device.

[0125] Among them, the above-mentioned first processing mode set includes a linear minimum mean square error algorithm and a Wiener filter, so that the receiving end device can use one of the two processing modes. Accordingly, the receiving end device can determine the processing mode based on the linear minimum mean square error algorithm or the Wiener filter to perform channel measurement, channel estimation, channel prediction, etc. on the channel on the received CSI RS-A according to factors such as channel conditions and service quality. The above-mentioned second processing mode set includes an iterative algorithm and a neural network, so that the receiving end device can use one of the two processing modes. Accordingly, the receiving end device can determine the processing mode based on the iterative algorithm or the neural network to perform channel measurement, channel estimation, channel prediction, etc. on the channel on the received CSI RS-B according to factors such as channel conditions and service quality. The above-mentioned third processing mode set includes a linear minimum mean square error, an iterative algorithm, and a neural network (which may include multiple models) algorithm, so that the receiving end device can use one of the three processing modes. Accordingly, the receiving end device can determine the processing mode based on the linear minimum mean square error, the iterative algorithm, or the neural network algorithm to perform channel measurement, channel estimation, channel prediction, etc. on the channel on the received CSI RS-C according to factors such as channel conditions and service quality. The fourth processing mode set includes a pre-agreed processing mode. Accordingly, the receiving end device can perform channel measurement, channel estimation, channel prediction, etc. on the channel on the received CSI RS-D according to the pre-agreed processing mode.

[0126] In some embodiments, the transmitting end device may further send indication information of different processing modes or sets of processing modes for different ports of the same channel state information reference signal.

[0127] In some embodiments, the processing mode is determined based on power information of the reference signal. For example, the processing mode is related to the power of the channel state information reference signal.

[0128] (11) Instruction information for the selection rule of the receiving end to select the processing method

[0129] Among them, the above-mentioned indication information is used to instruct the receiving device to select a selection rule for a target processing method from at least one received processing method (such as the above-mentioned processing method or processing method set), and the target processing method is the processing method selected from at least one processing method.

[0130] In some embodiments, a selection rule for selecting a target processing mode from at least one processing mode is determined based on at least one of channel quality information and channel reconstruction quality information. Exemplarily, the channel quality information may include at least one of information describing the channel conditions between the transmitter and receiver, such as the signal-to-noise ratio, signal-to-interference-plus-noise ratio, and reference signal received power, and the statistical distribution of channel parameters. The channel reconstruction quality information may include at least one of information such as the statistical distribution of the reconstructed channel and the similarity between the reconstructed channel and the measured channel.

[0131] For example, the selection rule may include selecting the neural network approach if the accuracy of the reconstructed channel reaches or exceeds 90%, and using the traditional codebook feedback approach if the accuracy of the reconstructed channel is less than 90%. Another example is the selection rule that the neural network approach may be used if the signal-to-noise ratio reaches or exceeds 15dB, and using the traditional codebook feedback approach, such as a Type 1 or Type 2 codebook, if the signal-to-noise ratio does not reach 15dB.

[0132] (12) Description of the selection rule for selecting the target reference signal from X reference signals

[0133] The target reference signal is a reference signal selected by the receiving device from among X received reference signals and used for feedback.

[0134] Exemplarily, a receiving device selects Y channel state information reference signals from X reference signals, such as channel state information references, to provide channel state information feedback.

[0135] In some embodiments, a selection rule for selecting the target reference signal from the X reference signals includes constraint information for selecting the target reference signal.

[0136] Exemplarily, the constraint information includes prohibiting the simultaneous selection of CSI RS-A and CSI RS-C. When the receiving device needs to select two target reference signals from the four received channel state information reference signals CSI RS-A, CSI RS-B, CSI RS-C, and CSI RS-D, there may be six selectable combinations of target reference signals: CSI RS-A and CSI RS-B, CSI RS-A and CSI RS-C, CSI RS-A and CSI RS-D, CSI RS-B and CSI RS-C, CSI RS-B and CSI RS-D, and CSI RS-C and CSI RS-D. Combined with the constraint information prohibiting the simultaneous selection of CSI RS-A and CSI RS-C, the selectable target reference signal combination of CSI RS-A and CSI RS-C is excluded, and the receiving device can also determine the target reference signal from the remaining five selectable combinations.

For example, this information may include information about the maximum number of bits allowed for transmission of channel state information feedback by the receiving device. The transmitting device may use this indication information to indicate to the receiving device that the maximum allowable number of bits for transmission of channel state information feedback is 20,000, thereby preventing the receiving device from transmitting more than 20,000 bits of channel state information.
