In the present application, the chip system can be composed of chips, or can include chips and other discrete devices. In the technical solution provided by the present application, the communication device being a terminal or a UE is taken as an example for description.

[0100] Optionally, a wireless communication system generally consists of cells, and network devices provide cell management. The network devices provide communication services to multiple mobile stations (MS) in the cell. The network devices include a baseband unit (BBU) and a remote radio unit (RRU). The BBU and the RRU can be placed in different locations. For example, the RRU is remote and placed in a high-traffic area, and the BBU is placed in the central computer room. The BBU and the RRU can also be placed in the same computer room. The BBU and the RRU can also be different components under one rack. Optionally, one cell can correspond to one carrier or a member carrier.

[0101] In some deployments, the network devices mentioned in the embodiments of the present application can be devices including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit-control plane, CU-CP) and a user plane CU node (central unit-user plane, CU-UP) and a DU node. For example, the network device can include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU.

[0102] Optionally, in the embodiments of the present application, a terminal or a network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and a memory (also called main memory). The operating system can be any one or more computer operating systems that implement service processing through processes. For example, Linux operating system, Unix operating system, Android operating system, iOS operating system, or Windows operating system, etc. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software. Moreover, the embodiments of the present application do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of the present application. It is only necessary to be able to communicate according to the method provided in the embodiments of the present application by running a program recording the code of the method provided in the embodiments of the present application. For example, the execution subject of the method provided in the embodiments of the present application can be a terminal or a network device, or a functional module in the terminal or the network device that can call and execute the program.

[0103] In other words, the relevant functions of the terminal or network device in the embodiments of the present application can be implemented by one device, can also be jointly implemented by multiple devices, or can also be implemented by one or more functional modules in one device. The embodiments of the present application do not make specific limitations thereto. It can be understood that the above functions can be either network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (such as a cloud platform).

[0104] The communication between the network device and the terminal follows a certain protocol layer structure. The protocol layer structure may include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure may include functions of protocol layers such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer. For example, the user plane protocol layer structure may include functions of protocol layers such as the PDCP layer, the RLC layer, the MAC layer, and the physical layer. In a possible implementation, a service data adaptation protocol (SDAP) layer may also be included above the PDCP layer.

[0105] Optionally, the protocol layer structure between the network device and the terminal may also include an artificial intelligence (AI) layer for transmitting data related to AI functions.

[0106] Taking the data transmission between the network device and the terminal as an example, the data transmission needs to pass through the user plane protocol layer, such as through the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer. Among them, the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer can also be collectively referred to as the access layer. According to the data transmission direction, it is divided into transmission or reception, and each of the above layers is further divided into a transmission part and a reception part. Taking the downlink data transmission as an example, after the PDCP layer obtains data from the upper layer, it transmits the data to the RLC layer and the MAC layer, and then the MAC layer generates a transport block, and then performs wireless transmission through the physical layer. The data is encapsulated correspondingly in each layer. For example, the data received by a certain layer from the upper layer of this layer is regarded as the service data unit (SDU) of this layer, and after being encapsulated by this layer, it becomes a protocol data unit (PDU), and then is passed to the next layer.

[0107] Exemplarily, the terminal may also have an application layer and a non-access stratum. Among them, the application layer can be used to provide services to the applications installed in the terminal. For example, the downlink data received by the terminal can be sequentially transmitted from the physical layer to the application layer, and then provided to the application by the application layer; for another example, the application layer can obtain the data generated by the application, and sequentially transmit the data to the physical layer and send it to other communication devices. The non-access stratum can be used to forward user data. For example, the uplink data received from the application layer is forwarded to the SDAP layer, or the downlink data received from the SDAP layer is forwarded to the application layer.

[0108] It should be understood that Figure 1A and Figure 1B The number and type of each device in the communication system shown are only for illustration, and this application is not limited thereto. In actual applications, the communication system may also include more terminals, more access network devices, and may also include other network elements. For example, it may include core network devices and / or network elements for implementing artificial intelligence functions.

[0109] It can be understood that all or part of the functions implemented by one or more of the terminal, the access network device, the core network device, or the network element for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of a dedicated processor or a general-purpose processor and corresponding software modules. Among them, since the terminal device and the access network device involve the interface for air interface transmission, the transceiver function of this interface can be implemented by hardware. Core network devices, such as operation administration and maintenance (OAM) network elements, can all be virtualized. Optionally, one or more functions of the virtualized terminal device, access network device, core network device, or network element for implementing artificial intelligence functions can be implemented by a cloud device, such as a cloud device in an over the top (OTT) system.

[0110] Figure 1A and Figure 1B The communication between the network device and the terminal in the communication system shown can also be represented in another form, such as Figure 2As shown in the figure, the terminal 10 includes a processor 101, a memory 102, and a transceiver 103. The transceiver 103 includes a transmitter 1031, a receiver 1032, and an antenna 1033. The network device 20 includes a processor 201, a memory 202, and a transceiver 203. The transceiver 203 includes a transmitter 2031, a receiver 2032, and an antenna 2033. The receiver 1032 can be used to receive transmission control information through the antenna 1033, and the transmitter 1031 can be used to send transmission feedback information to the network device 20 through the antenna 1033. The transmitter 2031 can be used to send transmission control information to the terminal 10 through the antenna 2033, and the receiver 2032 can be used to receive the transmission feedback information sent by the terminal 10 through the antenna 2033.

[0111] Among them, the processor 101 / processor 201 can be a CPU, a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the solution of the present application.

[0112] The memory 102 / memory 202 can be a device with a storage function. For example, it can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM), or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but not limited to this. The memory can exist independently and be connected to the processor through a communication line. The memory can also be integrated with the processor.

[0113] Among them, the memory 102 / memory 202 is used to store computer execution instructions for implementing the solution of the present application, and is controlled by the processor 101 / processor 201 for execution. The processor 101 / processor 201 is used to execute the computer execution instructions stored in the memory 102 / memory 202, so as to implement the communication method provided in the embodiments of the present application.

[0114] Alternatively, in the embodiments of the present application, it may also be that the processor 101 / processor 201 executes the functions related to processing in the communication method provided in the following embodiments of the present application.

[0115] The computer-executable instructions in the embodiments of the present application may also be referred to as application code, and the embodiments of the present application do not make specific limitations thereon.

[0116] In existing communication standards, terminals are supported to feedback the time domain channel property (TDCP), which is defined as the correlation information of two channel state information-reference signals (CSI-RS) at the transmission occasion, and the time interval between the two transmission occasions is multiple time units. This correlation information is beneficial for the base station to understand the change speed of the channel. For example, the base station can configure demodulation reference signals (DMRS) with different densities according to this information to adapt to different channel change situations. The delay multipath information of the downlink channel reflects the channel environment where the terminal is located, and different channel environments will lead to different system performances. For example, if the base station knows the base station delay and multipath information of the downlink channel, it is used to determine whether to use low-precision precoding or high-precision precoding for downlink transmission, and then instruct the terminal to report channel state information with different precisions. Although the terminal directly feedbacks the channel state information (such as precoding information), it can also reflect the channel environment information, and thus can assist the base station in making judgments on the scheduling algorithm. However, the computational complexity of the terminal feedbacking the precoding information is relatively high and the feedback overhead is relatively large. There is currently no corresponding solution on how to enable the network device to comprehensively obtain channel information with a relatively small overhead.

[0117] The present application provides a communication solution. The network device sends reference signals to the terminal on multiple transmission occasions and multiple frequency domain transmission units, and the terminal sends the first information to the network device to indicate multiple time domain characteristic values and multiple frequency domain characteristic values. Thus, the network device can comprehensively understand the change speed of the channel and the delay multipath information.

[0118] Based on the above communication system, the communication method provided by the present application is described below:

[0119] In this application, "sending information to... (such as a terminal)" or the relevant schematic in the drawings can be understood as the destination of the information being the terminal. This can include directly or indirectly sending information to the terminal. "Receiving information from... (such as a terminal)" or "receiving information sent from... (such as a terminal)", or the relevant schematic in the drawings can be understood as the source of the information being the terminal, which can include directly or indirectly receiving information from the terminal. Necessary processing may be performed on the information between the source and destination of the information transmission, such as format changes, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be elaborated here.

[0120] It can be understood that in this application, the terminal and the network device are used as examples of the execution entities of the interaction schematic, but this application does not limit the execution entities of the interaction schematic. For example, the terminal in the method provided in this application can also be a chip, a chip system, or a processor applied to the terminal, and can also be a logical node, a logical module, or software that can implement all or part of the functions of the terminal; the network device in the method provided in this application can also be a chip, a chip system, or a processor applied to the network device, and can also be a logical node, a logical module, or software that can implement all or part of the functions of the network device.

[0121] It can be understood that in each of the above embodiments, the method and / or steps implemented by the terminal can also be implemented by components applicable to the terminal (such as chips or circuits); the method and / or steps implemented by the network device can also be implemented by components applicable to the network device (such as chips or circuits).

[0122] As Figure 3 shown, it is a schematic flowchart of a communication method provided by an embodiment of this application. Exemplarily, the method may include the following steps:

[0123] S301. The network device sends a reference signal to the terminal on multiple transmission opportunities and multiple frequency-domain transmission units. Correspondingly, the terminal receives the reference signal on multiple transmission opportunities and multiple frequency-domain transmission units.

[0124] One transmission opportunity may include one or more time units, and the time unit can be any one of a subframe, a slot, a mini-slot, or a symbol. The embodiments of this application do not limit this. The network device can configure the size of the transmission opportunity. For example, the number of slots included in one transmission time.

[0125] As Figure 4As shown, it is a schematic diagram of the transmission opportunity and time interval in an embodiment of the present application. Two transmission opportunities are illustrated in the figure: the first transmission opportunity and the second transmission opportunity. The first transmission opportunity and the second transmission opportunity each include a number of time units. There is a certain time interval between the first transmission opportunity and the second transmission opportunity.

[0126] Among them, the time interval is the interval in the time domain between every two transmission opportunities.

[0127] The network device sends reference signals to the terminal at multiple transmission opportunities.

[0128] Exemplarily, in order to further improve the channel measurement accuracy, the time domain density of the reference signal is greater than or equal to a first threshold. The time domain density can be understood as the number of time units to which the reference signal is mapped in a transmission opportunity.

[0129] One frequency domain transmission unit may include one or more resource blocks (RBs). The network device can configure the size of the frequency domain transmission unit. For example, the number of RBs included in one frequency domain transmission unit.

[0130] In addition, an existing frequency domain division method can also be reused. One frequency domain transmission unit may include one or more subbands. The determination method of the subband is the same as the method for determining the subband when the terminal feeds back the subband channel quality indicator (CQI) or the subband precoding matrix indicator (PMI). Among them, one subband includes one or more RBs.

[0131] As Figure 5 shown, it is a schematic diagram of the frequency domain transmission unit and the frequency domain interval in an embodiment of the present application. Two frequency domain transmission units are illustrated in the figure: the first frequency domain transmission unit and the second frequency domain transmission unit. The first frequency domain transmission unit and the second frequency domain transmission unit each include a number of RBs or a number of subbands. There is a certain frequency domain interval between the first frequency domain transmission unit and the second frequency domain transmission unit.

[0132] Among them, the frequency domain interval is the interval in the frequency domain between every two frequency domain transmission units.

[0133] In one example, one frequency domain interval may include one or more RBs. The number of RBs included in the frequency domain interval can be configured by the network device.

[0134] In another example, one frequency domain interval may include one or more subbands. The number of subbands included in the frequency domain interval can be configured by the network device.

[0135] The network device sends reference signals to the terminal on multiple frequency-domain transmission units.

[0136] Exemplarily, the above reference signal may be a reference signal specifically for channel tracking, that is, a tracking reference signal (TRS). For the reference signal used for channel tracking, the transmission density in the time domain and the frequency domain is relatively high, which helps to improve the channel measurement accuracy.

[0137] Of course, the embodiments of the present application are not limited to the type of the reference signal, and it may also be a channel state information-reference signal (CSI-RS), etc.

[0138] Exemplarily, in order to further improve the channel measurement accuracy, the frequency-domain density of the reference signal is greater than or equal to a second threshold. The frequency-domain density can be understood as the number of resource elements (REs) to which the reference signal is mapped on one RB.

[0139] S302. The terminal sends first information to the network device. Correspondingly, the terminal receives the first information.

[0140] Wherein, the first information is used to indicate a plurality of time-domain characteristic values and a plurality of frequency-domain characteristic values.

[0141] Wherein, each time-domain characteristic value among the plurality of time-domain characteristic values includes the time-domain characteristic value between every two of the plurality of transmission opportunities, and the time-domain characteristic value is the correlation information between the measurement results of the reference signals on every two transmission opportunities;

[0142] Each frequency-domain characteristic value among the plurality of frequency-domain characteristic values includes the frequency-domain characteristic value between every two of the plurality of frequency-domain transmission units, and the frequency-domain characteristic value is the correlation information between the measurement results of the reference signals on every two frequency-domain transmission units.

[0143] In a specific implementation, after the terminal receives the reference signals sent by the network device on multiple transmission opportunities, it measures the reference signals received on each of the multiple transmission opportunities respectively, and obtains the measurement results of the reference signals on each transmission opportunity. For example, the measurement result of the reference signal on the first transmission opportunity is the channel information h1(n), n = 1, 2,..., T; the measurement result of the reference signal on the second transmission opportunity is the channel information h2(n), n = 1, 2,..., T.

[0144] The terminal obtains multiple time-domain characteristic values according to the measurement results of the reference signal on multiple transmission occasions. Among them, each time-domain characteristic value among the multiple time-domain characteristic values includes the time-domain characteristic value between every two of the multiple transmission occasions, and the time-domain characteristic value is the correlation information between the measurement results of the reference signal on every two transmission occasions. The correlation information between the measurement results of the reference signal on every two transmission occasions is the correlation information between the measurement result of the reference signal in the first transmission occasion and the measurement result in the second transmission occasion. For example, the correlation information of the measurement results can be the cross-correlation of two sequences h1(n) and h2(n).

[0145] The correlation information between the measurement result of the first transmission occasion and the measurement result of the second transmission occasion reflects the correlation degree of the channel at different transmission occasions. If the correlation degree is relatively high, it reflects that the change of the channel in the time domain is small, which can to a certain extent indicate that the moving speed of the terminal is slow and the influence of Doppler frequency offset on the channel is small; if the correlation degree is relatively low, it reflects that the change of the channel in the time domain is large, which can to a certain extent indicate that the moving speed of the terminal is fast and the influence of Doppler frequency offset on the channel is large. That is, the correlation information between the measurement result of the first transmission occasion and the measurement result of the second transmission occasion can reflect the change speed of the channel in the time domain.

[0146] After the terminal receives the reference signal sent by the network device on multiple frequency-domain transmission units, it measures the reference signal received on each of the multiple frequency-domain transmission units respectively, and obtains the measurement result of the reference signal on each frequency-domain transmission unit. For example, the measurement result of the reference signal on the first frequency-domain transmission unit is the channel information H1(n), n = 1, 2,..., F; the measurement result of the reference signal on the second frequency-domain transmission unit is the channel information H2(n), n = 1, 2,..., F.

[0147] The terminal obtains multiple frequency-domain channel property (FDCP) values according to the measurement results of the reference signal on multiple frequency-domain transmission units. Among them, each frequency-domain channel property value among the multiple frequency-domain channel property values includes the frequency-domain channel property value between every two of the multiple frequency-domain transmission units, and the frequency-domain channel property value is the correlation information between the measurement results of the reference signal on every two frequency-domain transmission units. The correlation information between the measurement results of the reference signal on every two frequency-domain transmission units is the correlation information between the measurement result of the reference signal on the first frequency-domain transmission unit and the measurement result on the second frequency-domain transmission unit. For example, the correlation information of the measurement results can be the cross-correlation of two sequences H1(n) and H2(n).

[0148] The correlation information of the measurement results of the first frequency-domain transmission unit and the measurement results of the second frequency-domain transmission unit reflects the correlation degree of the channel in different frequency-domain transmission units. If the correlation degree is relatively high, it reflects that the channel changes less in the frequency domain (that is, the degree of channel selective fading is relatively low), which can to a certain extent indicate that there are fewer time-domain paths of the channel or there are time-delay paths with higher power; if the correlation degree is relatively low, it reflects that the channel changes more in the frequency domain (that is, the degree of channel selective fading is relatively high), which can to a certain extent indicate that there are more time-domain paths of the channel or the powers of multiple time-delay paths are relatively consistent. That is, the correlation information of the measurement results can reflect the multipath situation of the channel in the time domain. Therefore, the network device can obtain the time-delay multipath information of the downlink channel according to the multiple frequency-domain characteristic values, thereby obtaining the channel environment where the terminal is located, which is beneficial to improving the system performance.

[0149] The terminal sends the first information to the network device. Among them, the first information is used to indicate multiple time-domain characteristic values and multiple frequency-domain characteristic values. Exemplarily, the first information includes multiple time-domain characteristic values and multiple frequency-domain characteristic values.

[0150] Among them, the time-domain characteristic value may include the correlation information between the measurement results of the first transmission opportunity and the measurement results of the second transmission opportunity, and the time-domain characteristic value includes amplitude information and / or phase information.

[0151] Among them, the reporting of the amplitude information in the time-domain characteristic value may be to quantize the amplitude information of the measurement results of the first transmission opportunity and the measurement results of the second transmission opportunity by a plurality of bits and then carry it in the first information for reporting. Among them, the number of quantization bits can be configured by the network device.

[0152] Among them, the reporting of the phase information in the time-delay characteristic value may also be to quantize the phase information of the measurement results of the first transmission opportunity and the measurement results of the second transmission opportunity by a plurality of bits and then carry it in the first information for reporting. Among them, the number of quantization bits can be configured by the network device.

[0153] Exemplarily, the priority of the amplitude information of the time-domain characteristic value in the first information may be higher than that of the phase information of the time-domain characteristic value. When information with a higher mapping order or a higher priority is subjected to channel coding, its error probability is lower, so it can be used to transmit more important information.

[0154] Among them, the frequency-domain characteristic value may include the correlation information of the measurement results of the first frequency-domain transmission unit and the measurement results of the second frequency-domain transmission unit, and the frequency-domain characteristic value includes amplitude information and / or phase information.

[0155] Among them, the reporting of the amplitude information in the frequency-domain characteristic value can be to quantize the amplitude information of the measurement results of the first frequency-domain transmission unit and the measurement results of the second frequency-domain transmission unit by a plurality of bits, and carry it in the first information for reporting. Among them, the number of quantization bits can be configured by the network device.

[0156] Among them, the reporting of the phase information in the frequency-domain characteristic value can also be to quantize the phase information of the measurement results of the first frequency-domain transmission unit and the measurement results of the second frequency-domain transmission unit by a plurality of bits, and carry it in the first information for reporting. Among them, the number of quantization bits can be configured by the network device.

[0157] Exemplarily, the priority of the amplitude information of the frequency-domain characteristic value in the first information can be higher than the phase information of the frequency-domain characteristic value. When information with a higher mapping order or a higher priority is subjected to channel coding, its error probability is lower, so that it can be used to transmit more important information.

[0158] Furthermore, the terminal can perform wideband normalization on each of the obtained multiple frequency-domain characteristic values, and then carry the normalized multiple frequency-domain characteristic values in the first information, which can save signaling overhead.

[0159] In this first information, the reported information can be mapped according to any of the following mapping methods:

[0160] In one implementation, the order of mapping multiple time-domain characteristic values and multiple frequency-domain characteristic values in the first information is:

[0161] The amplitude values included in the multiple time-domain characteristic values;

[0162] The amplitude values included in the multiple frequency-domain characteristic values;

[0163] The phase values included in the multiple time-domain characteristic values;

[0164] The phase values included in the multiple frequency-domain characteristic values.

[0165] In another implementation, the order of mapping multiple time-domain characteristic values and multiple frequency-domain characteristic values in the first information is:

[0166] The amplitude values included in the multiple frequency-domain characteristic values;

[0167] The amplitude values included in the multiple time-domain characteristic values;

[0168] The phase values included in the multiple frequency-domain characteristic values;

[0169] The phase values included in the multiple time-domain characteristic values.

[0170] In yet another implementation, the order of mapping multiple time-domain characteristic values and multiple frequency-domain characteristic values in the first information is:

[0171] The amplitude values included in multiple time-domain characteristic values;

[0172] The phase values included in multiple time-domain characteristic values;

[0173] The amplitude values included in multiple frequency-domain characteristic values;

[0174] The phase values included in multiple frequency-domain characteristic values.

[0175] In yet another implementation, the order of mapping multiple time-domain characteristic values and multiple frequency-domain characteristic values in the first information is:

[0176] The amplitude values included in multiple frequency-domain characteristic values;

[0177] The phase values included in multiple frequency-domain characteristic values;

[0178] The amplitude values included in multiple time-domain characteristic values;

[0179] The phase values included in multiple time-domain characteristic values.

[0180] In the above mapping method, the information with a higher mapping order or higher priority has a lower error probability during channel coding, and thus can be used to transmit more important information.

[0181] Further, the terminal can send the above first information non-periodically (for example, the network device triggers the terminal to report through downlink control information (DCI)). This first information is carried on the physical uplink shared channel (PUSCH).

[0182] According to a communication method provided by an embodiment of the present application, the network device sends a reference signal to the terminal on multiple transmission opportunities and multiple frequency-domain transmission units, and the terminal sends the first information to the network device to indicate multiple time-domain characteristic values and multiple frequency-domain characteristic values. Thus, the network device can comprehensively understand the change speed of the channel and the delay multipath information.

[0183] In a further embodiment, the number of the above time-domain characteristic values and frequency-domain characteristic values can be configured. The following is further described in detail through embodiments:

[0184] As Figure 6 shown, it is a schematic flowchart of yet another communication method provided by an embodiment of the present application. Exemplarily, the method may include the following steps:

[0185] S601. The network device sends the second information to the terminal. Correspondingly, the terminal receives the second information.

[0186] Among them, the second information is used to configure the resources corresponding to the reference signal.

[0187] Exemplarily, the reference signal for measuring multiple time-domain characteristic values and multiple frequency-domain characteristic values can be the same resource or the same resource set.

[0188] Exemplarily, the second information can be carried in any one of the following messages: radio resource control (RRC) signaling, DCI, medium access control control element (MAC CE).

[0189] S602. The network device sends the third information to the terminal. Correspondingly, the terminal receives the third information.

[0190] Among them, the third information is used to indicate at least one of the following information:

[0191] The number of reported time-domain characteristic values;

[0192] The time-domain interval associated with each time-domain characteristic value among the multiple time-domain characteristic values;

[0193] The number of reported frequency-domain characteristic values;

[0194] The frequency-domain interval associated with each frequency-domain characteristic value among the multiple frequency-domain characteristic values;

[0195] Whether to report the phase value included in the time-domain characteristic value;

[0196] Whether to report the phase value included in the frequency-domain characteristic value.

[0197] Regarding the above indications, the following descriptions are given separately:

[0198] (1) It can be understood that the larger the number of reported time-domain characteristic values, the more accurately the network side can obtain the channel environment of the downlink channel. However, the signaling overhead is also greater. The network device can configure the number of time-domain characteristic values that the terminal needs to report.

[0199] Alternatively, the terminal can also report the number of time-domain characteristic values to be reported.

[0200] Among them, the number of time-domain characteristic values can be related to the number of transmission opportunities included in the reference signal or the number of subbands included in the reference signal. For example, if the number of transmission opportunities included in the reference signal is P, then the number of time-domain characteristic values is P - 1. Where P is a positive integer.

[0201] (2) In one example, each of the multiple time-domain characteristic values can be associated with the same time interval. The network device obtains multiple time-domain characteristic values associated with the same time interval fed back by the terminal, which helps to improve the estimation accuracy / confidence of the time-domain characteristic values.

[0202] For example, a time interval can include one or more time slots. The number of time slots included in the time interval can be configured by the network device.

[0203] Again, for example, a time interval can include one or more sub-frames. The number of sub-frames included in the time interval can be configured by the network device.

[0204] In another example, each of the multiple time-domain characteristic values can be associated with a different time interval. If different time-domain characteristic values are associated with different time intervals, then the multiple time-domain characteristic values can reflect the channel variation conditions in a larger time domain range.

[0205] The network device can configure a time interval for each of the multiple time-domain characteristic values. Further, the order in which the multiple time-domain characteristic values are mapped in the first information is associated with the configuration order of the multiple time intervals. For example, the order in which the multiple time-domain characteristic values are mapped in the first information corresponds one-to-one with the configuration order of the multiple time intervals, that is, the order in which the multiple time-domain characteristic values are mapped in the first information is the same as the order of the multiple time intervals configured by the network device.

[0206] The time interval associated with each of the multiple time-domain characteristic values can also be related to the mapping order of the multiple time-domain characteristic values in the first information. For example, the time interval associated with the first time-domain characteristic value mapped in the first information is 1 transmission opportunity; the time interval associated with the second time-domain characteristic value mapped in the first information is 2 transmission opportunities; and so on, the time interval associated with the Qth time-domain characteristic value mapped in the first information is P transmission opportunities.

[0207] The network device can indicate the time interval associated with each of the multiple time-domain characteristic values.

[0208] (3) It can be understood that the larger the number of reported frequency-domain characteristic values, the more accurately the network side can obtain the channel environment of the downlink channel. However, the signaling overhead is also greater. The network device can configure the number of frequency-domain characteristic values that the terminal needs to report.

[0209] Alternatively, the terminal can also report the number of frequency-domain characteristic values to be reported.

[0210] Among them, the number of frequency-domain characteristic values may be related to the number of frequency-domain transmission units included in the reference signal or the number of subbands included in the reference signal. For example, if the number of frequency-domain transmission units included in the reference signal is M, the number of frequency-domain characteristic values is M - 1; for another example, if the number of subbands included in the reference signal is M, the number of frequency-domain characteristic values is M - 1. Herein, M is a positive integer.

[0211] (4) In one example, each of the multiple frequency-domain characteristic values may be associated with the same frequency-domain interval. The network device obtaining multiple frequency-domain characteristic values associated with the same frequency-domain interval fed back by the terminal helps to improve the estimation accuracy / confidence level of the frequency-domain characteristic values.

[0212] For example, one frequency-domain interval may include one or more RBs. The number of RBs included in the frequency-domain interval may be configured by the network device.

[0213] For another example, one frequency-domain interval may include one or more subbands. The number of subbands included in the frequency-domain interval may be configured by the network device.

[0214] In another example, each of the multiple frequency-domain characteristic values may be associated with a different frequency-domain interval. If different frequency-domain characteristic values are associated with different frequency-domain intervals, then the multiple frequency-domain characteristic values can reflect the channel variation in a larger frequency range.

[0215] The network device may configure a frequency-domain interval for each of the multiple frequency-domain characteristic values. Further, the order of mapping the multiple frequency-domain characteristic values in the first information is associated with the configuration order of the multiple frequency-domain intervals. For example, the order of mapping the multiple frequency-domain characteristic values in the first information corresponds one-to-one with the configuration order of the multiple frequency-domain intervals, that is, the order of mapping the multiple frequency-domain characteristic values in the first information is the same as the order of the multiple frequency-domain intervals configured by the network device.

[0216] The frequency-domain interval associated with each of the multiple frequency-domain characteristic values may also be related to the mapping order of the multiple frequency-domain characteristic values in the first information. For example, the frequency-domain interval associated with the first frequency-domain characteristic value mapped in the first information is 1 frequency-domain transmission unit; the frequency-domain interval associated with the second frequency-domain characteristic value mapped in the first information is 2 frequency-domain transmission units; and so on, the frequency-domain interval associated with the Nth frequency-domain characteristic value mapped in the first information is N frequency-domain transmission units. For another example, the frequency-domain interval associated with the first frequency-domain characteristic value mapped in the first information is 1 subband; the frequency-domain interval associated with the second frequency-domain characteristic value mapped in the first information is 2 subbands; and so on, the frequency-domain interval associated with the Nth frequency-domain characteristic value mapped in the first information is N subbands.

[0217] The network device may indicate the frequency-domain interval associated with each of the multiple frequency-domain characteristic values.

[0218] (5) Feeding back the phase information of the time-domain characteristic value can enable the network device to obtain more channel information. Assume that S(1) is the time-domain characteristic value obtained from two transmission opportunities separated by one time interval, S(2) is the time-domain characteristic value obtained from two transmission times separated by two time intervals, and so on until S(Q). After the network device obtains the sequence S(q), n = 1, 2, …, Q, it can obtain the Doppler power spectrum through Fourier transform, and this Doppler power spectrum reflects more time-domain channel characteristics (such as the power magnitudes of different frequency offsets).

[0219] Generally, the priority of the amplitude information of the time-domain characteristic value can be higher than that of the phase information of the time-domain characteristic value. Therefore, the network device can indicate whether to report the phase value included in the time-domain characteristic value. The terminal can report accurately according to this indication.

[0220] (6) Feeding back the phase information can enable the network device to obtain more channel information. Assume that R(1) is the frequency-domain characteristic value obtained from two frequency-domain transmission units separated by one sub-band, R(2) is the frequency-domain characteristic value obtained from two frequency-domain transmission units separated by two sub-bands, and so on until R(N). After the network device obtains the sequence R(n), n = 1, 2, …, N, it can obtain the power delay profile in the time domain through Fourier transform, and this power delay profile reflects more frequency-domain channel characteristics (such as the power magnitudes of different delay paths).

[0221] Generally, the priority of the amplitude information of the frequency-domain characteristic value can be higher than that of the phase information of the time-domain characteristic value. Therefore, the network device can indicate whether to report the phase value included in the frequency-domain characteristic value. The terminal can report accurately according to this indication.

[0222] Exemplarily, the third information can be carried in any one of the following messages: RRC signaling, DCI, MAC CE.

[0223] It can be understood that the above second information and third information can be carried in the same message or different messages.

[0224] S603. The network device sends reference signals to the terminal on multiple transmission opportunities and multiple frequency-domain transmission units. Correspondingly, the terminal receives the reference signals on multiple transmission opportunities and multiple frequency-domain transmission units.
