[0021] In this application, indicators of various parameters may be referred to as indices or identifiers (IDs), which are completely equivalent concepts. For example, an indicator may be a resource identifier of a wireless system, where the wireless system resource includes, but is not limited to, one of the corresponding indices of one reference signal resource, a reference signal resource group, a reference signal resource configuration, a Channel State Information (CSI) report, a CSI report set, a terminal, a base station, a panel, a neural network, a sub-neural network, a neural network layer, etc. The base station can indicate the identifier of one or a set of resources to the terminal via various higher layer signaling or physical layer signaling.

[0022] In some embodiments, artificial intelligence (AI) includes devices, assemblies, software, and modules with self-learning, such as machine learning (ML), deep learning, reinforcement learning, transfer learning, deep reinforcement learning, and meta-learning. In some embodiments, artificial intelligence is realized by an artificial intelligence network (also called a neural network), which includes multiple layers, each layer including at least one node.

A network model defines the architecture of a network, such as the number of layers of the neural network, the size of each layer, the activation function, the link status, the convolution kernel and size of the convolution step, and the convolution type (e.g., 1D convolution, 2D convolution, 3D convolution, dilated convolution, transpose convolution, split convolution, grouped convolution, dilated convolution, etc.), and the network parameters are the weights and / or biases of each layer network in the network model and their values. A network model can support multiple sets of different neural network parameter values to adapt to different scenes.A neural network model can correspond to multiple different neural network parameter values.

[0024] In some embodiments, transmitting includes sending or receiving, for example, sending data or signals and receiving data or signals.

[0025] In some embodiments, a base station or a user may need to transmit a reference signal (RS) to calculate channel state information or perform channel estimation, mobility management, positioning, etc., including, but not limited to, a Channel-State Information reference signal (CSI-RS), including a zero-power CSI-RS (Zero Power CSI-RS, ZP CSI-RS) and a non-zero-power CSI-RS (Non-Zero Power CSI-RS, NZP CSI-RS), a Channel-State Information-Interference Measurement signal (CSI-IM), a Sounding Reference Signal (SRS), a Synchronization Signals Block (SSB), a Physical Broadcast Channel (PBCH), and a Synchronization Signals Block / Physical Broadcast Channel (SSB / PBCH). The NZP CSI-RS may be used to measure the channel or interference, the CSI-RS may be used for tracking, and a tracking reference signal (CSI-RS for The CSI-IM is generally used to measure interference, and the SRS is used to perform channel estimation. A set of resource elements (REs) included in the time-frequency resource for transmitting reference signals is called a reference signal resource, such as a CSI-RS resource, an SRS resource, a CSI-IM resource, or an SSB resource. In this specification, SSB includes a synchronization signal block and / or a physical broadcast channel.

[0026] In some embodiments, in a communication system, resources that transmit reference signals may be referred to as reference signal resources, and in order to save signaling overhead, etc., multiple reference signal resources may be combined into one set (e.g., a CSI-RS resource set, a CSI-IM resource set, an SRS resource set), where one reference signal resource set includes at least one reference signal resource, and the multiple reference signal resource sets can all configure reference signal parameter information from the same reference signal resource setting (e.g., a CSI-RS resource setting, an SRS resource setting, where the CSI-RS resource setting may be combined with a CSI-IM resource setting, both of which are referred to as a CSI-RS resource setting).

[0027] In some embodiments, the base station configures measurement resources, and the measurement resources are used to obtain measurement parameters, where the measurement resources are C N Channel Measurement Resources (CMR) and / or C M Interference Measurement Resources (IMR), C N and C Mis a positive integer. The base station configures measurement resources with one report configuration or reporting setting. In some examples, one channel measurement resource includes at least one channel reference signal resource setting, for example, at least one CSI-RS resource setting or at least one SRS resource setting, and one interference measurement resource information includes at least one interference reference signal resource setting, for example, at least one CSI-IM resource setting. In some examples, one channel measurement resource includes at least one channel reference signal resource set, for example, at least one CSI-RS resource set or at least one SRS resource set, and one interference measurement resource includes at least one interference reference signal resource set, for example, at least one CSI-IM resource set. In some examples, one channel measurement resource includes at least one channel reference signal resource, for example, at least one CSI-RS resource or at least one SRS resource, and one interference measurement resource includes at least one interference reference signal resource, for example, at least one CSI-IM resource.

[0028] In some examples, to better transmit data or signals, a base station or a terminal needs to acquire measurement parameters, and the measurement parameters may include channel state information or other parameters for describing a channel, where the channel state information may include at least one of a Channel State Information - Reference Signal Resource Indicator (CSI-RS Resource Indicator, CRI), a Synchronization Signals Block Resource Indicator (SSBRI), a Reference Signal Received Power (RSRP), a Differential RSRP, a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Layer Indicator (LI), a Rank Indicator (RI), a Level 1 Signal to Interference plus Noise Ratio (L1-sinr), a Differential L1-SINR, and precoding information. Here, the precoding matrix indicator is a type of precoding information, i.e., a situation in which precoding information is realized based on a codebook, such as first-class precoding information. The precoding information also includes a form realized based on a non-codebook, such as second-class precoding information. In one example, CSI including only first-class precoding information is called first-class CSI, and CSI including second-class precoding information is called second-class CSI.

[0029] In some embodiments, the terminal and the base station transmit channel state information matching the channel using first-class precoding information, which is precoding information configured based on a conventional channel characteristic matrix or quantized values of the characteristic matrix. For example, a codebook-based method may be used, such as a codebook for N antennas in LTE (where N=2, 4, 8, 12, 16, 24, or 32), or a type I codebook, type II codebook, type II port selection codebook, enhanced type II codebook, enhanced type II selection codebook, or further enhanced type II selection codebook in NR. Here, the codebook includes L codewords, and the main idea is that the base station and the terminal store the L codewords based on a predetermined formula, table, or dictionary. In some examples, the codeword is a vector. In some examples, the codeword is a matrix, which includes r columns, each of which is a vector. In one embodiment, each column of the matrix is orthogonal to one another. In some examples, the vector constituting the codeword is a vector between 0 and 1, where only one value in the entire vector is 1 and the other values are 0. In some examples, the vector constituting the codeword is a DFT vector (Discrete Fourier Transform, DFT). In some examples, the vector constituting the codeword is obtained by tensor multiplying two or more DFT vectors (Kronecker product). In some examples, the vector constituting the codeword is obtained by multiplying two or more DFT vectors by different phases and then rotating and concatenating them. In some examples, the vector constituting the codeword is obtained by multiplying two or more DFT vectors by phases and then rotating them using a tensor product (Kronecker product).A base station or a terminal searches for L codewords to find a codeword that best matches the channel and transmits data or signals as the optimal codeword. Here, the codeword that matches the channel includes, but is not limited to, at least one of a codeword having the smallest distance from the channel, a codeword having the largest correlation with the channel, a codeword having the smallest distance from the optimal right singular vector or matrix of the channel, a codeword having the largest correlation with the optimal right singular vector or matrix of the channel, a codeword having the largest signal-to-noise ratio obtained by channel calculation, etc. L is an integer greater than 1, and generally, L is greater than the number of transmit antennas.

[0030] In some examples, the terminal and the base station transmit channel state information that matches the channel according to the second-class precoding information. The second-class precoding information is the channel state information obtained based on AI. In one example, it is the channel state information obtained by the base station and the terminal via the encoder of the self-encoder. The self-encoder includes one encoder and one decoder. Here, the encoder is in the terminal while the decoder is on the base station side. The terminal compresses the channel H obtained via the encoder to obtain the compressed H1, quantizes the compressed channel H1, and feeds it back to the base station. The base station receives the quantized H1, inputs it to the decoder after inverse quantization, and the decoder expands it to restore H. In one example, H includes K0 elements. The terminal selects K elements from H as H1, quantizes H1, and feeds it back. The base station receives the K quantized elements, inverse quantizes them, inputs the K inverse quantized elements to the AI module, and the AI module outputs K0 elements as the restoration to H, thereby obtaining the precoding matrix of H. Here, K and K0 are integers greater than 1, and K < K0. Here, both the compressed H1 or the K elements selected from H are the second-class precoding information. Also, for simplicity, the quantized H1 is also called the second-class precoding information. In one example, the second-class precoding information may be a precoding matrix different from the first-class precoding information generated by other non-AI methods. In one example, the second-class precoding information may be a precoding matrix other than the first-class precoding information.

[0031] In some examples, to transmit CSI, for example, a terminal feeds back the CSI and a base station receives the CSI. The terminal and the base station need to define one CSI report (CSI report or CSI report config), where the CSI report defines at least one of parameters such as a time-frequency resource for feeding back CSI, a report quantity (report quantity) included in the CSI, a time-domain type (report config type) fed back by the CSI, a channel measurement resource, an interference measurement resource, and a measured bandwidth size. The CSI report can be transmitted on uplink transmission resources, where the uplink transmission resources include the PUSCH and the PUCCH, and also includes time-domain characteristics including a periodic CSI report (P-CSI), an aperiodic CSI report (AP-CSI), and a semi-persistent CSI report (SP-CSI). Generally, P-CSI transmission has a relatively small number of bits and is performed on the PUCCH, A-CSI transmission has a large number of bits and is generally performed on the PUSCH, and SP-CSI may be transmitted based on the PUSCH or based on the PUCCH. Here, P-CSI transmitted based on the PUCCH is generally configured by higher layer signaling (Radio Resource Control, RRC), SP-CSI transmitted based on the PUCCH is also configured or activated by higher layer signaling (RRC and / or MAC CE), and both SP-CSI and A-CSI transmitted based on the PUSCH are triggered by physical layer signaling (downlink control information, DCI), and DCI is generally transmitted on a physical downlink control channel (PDCCH).In the present embodiment, the feedback CSI may be referred to as transmission CSI or transmission CSI, for example, feedback or transmission of channel state information carried on uplink transmission resources. The uplink transmission resources and corresponding CSI both report indications via channel state information. In the present embodiment, feedback of one CSI report refers to feedback of channel state information corresponding to the CSI report.

[0032] In an embodiment of the present application, a base station configures N CSI reports for a terminal via higher layer signaling and / or physical layer signaling, where each CSI report has an index value (identity, ID) called a CSI report. The terminal can select M CSI reports from the N CSI reports according to its own calculation or processing capability and a request from the base station. Based on uplink feedback resources, the terminal feeds back channel state information corresponding to at least one CSI report from the M CSI reports, where N and M are positive integers and M<=N. In one example, M CSI reports need to be fed back, but corresponding transmission resources of at least two reports among the M reports are inconsistent. The inconsistency of corresponding transmission resources of two reports refers to at least one symbol being identical and / or at least one subcarrier being identical in corresponding transmission resources (e.g., PUCCH or PUSCH) for feeding back the two reports.

[0033] In some examples, the channel information is information for describing a channel environment between communication nodes obtained based on a reference signal (e.g., CSI-RS), such as a time-domain channel matrix or a frequency-domain channel matrix. In some examples, the channel information is a complex matrix related to the number of transmit antennas Nt, the number of receive antennas Nr, and resource elements (REs). For example, one physical resource block has at least one Nr*Nt channel matrix.

[0034] As shown in FIG. 2, an embodiment of the present application provides a measurement parameter feedback method 200, which can be performed by a terminal, in other words, the method can be performed by software or hardware installed in the terminal, and the method includes S202, S204, S206, and S208.

[0035] S202: Receive a first signaling and measurement resource.

[0036] In one embodiment, the first signaling is used to process one of the following: indicating a measurement type; activating a measurement type switch; indicating a measurement type and activating a measurement resource; or switching a measurement type and activating a measurement resource.

[0037] Here, there is a correspondence between the measurement type and the measurement parameters, and the measurement resource includes at least one reference signal resource. In one embodiment, artificial intelligence (AI) can be used to efficiently feedback CSI. As the channel environment changes, the measurement type may be updated, i.e., a different measurement method or measurement module or a different artificial intelligence network may be used to obtain measurement parameters. For example, if the current artificial intelligence network (the AI network includes a neural network model and / or neural network parameters corresponding to the neural network model, the neural network model may be abbreviated as network model, and the neural network parameters may be abbreviated as network parameters) is not compatible with the current scene, a new AI network needs to be updated to measure and feedback CSI. For example, a new AI network may be activated using higher layer signaling. In this case, a first signaling may instruct the terminal to activate a measurement type switch. For example, the first signaling may instruct the terminal to subsequently measure using a new AI network. The measurement using the new AI network is referred to as a second measurement type, and the measurement using the original AI network is referred to as a first measurement type. In one example, the terminal may subsequently instruct that it needs to measure using a new measurement module, and measuring using the new measurement module is referred to as the second measurement type, and measuring using the original measurement module is referred to as the first measurement type. In one example, the terminal may subsequently instruct that it needs to measure using a new measurement method, and measuring using the new measurement method is referred to as the second measurement type, and measuring using the original measurement method is referred to as the first measurement type. In one example, the measurement type used by the terminal before the first instruction signaling is enabled is the first measurement type, and the measurement type used by the terminal after the first instruction signaling is enabled is the second measurement type.After the first instruction signaling is enabled, if the terminal is unable to acquire measurement parameters using the second measurement type in time, it may roll back to acquiring measurement parameters using the default measurement type, or may still acquire measurement parameters using the first measurement type. In one example, the terms "first" and "second" in the first and second measurement types are used only to distinguish whether the terminal uses a new AI network, a new measurement module, or a new measurement method when making measurements, or the original AI network, the original measurement module, or the original measurement method.

[0038] The measurement resource includes at least one reference signal resource, for example, the measurement resource is C N Channel Measurement Resources (CMR) and / or C M Interference Measurement Resources (IMR), C N and C M is a positive integer. The reference signal resource is included.

[0039] 3 is a schematic diagram of receiving the first signaling and measurement resources. As shown in FIG. 3, if the AI network needs to be updated for AI-based CSI measurement and feedback, for example, the first AI network is originally used, and then the first signaling activates AI network switching to use the second AI network. After receiving the first signaling, the terminal must wait a certain time before enabling the second AI network.

[0040] In one example, the first signaling is higher layer signaling or a field in higher layer signaling, the field including at least one bit. In one example, the first signaling is physical layer signaling or a field in physical layer signaling, the field including at least one bit. In one example, the first signaling is higher layer signaling and physical layer signaling, where the higher layer signaling includes, but is not limited to, RRC signaling and / or MACCE signaling. The physical layer signaling includes DCI signaling transmitted on a PDCCH.

[0041] In some examples, the time of transmitting the first signaling, the time of enabling the first signaling, the time of transmitting measurement resources, the time of measuring the measurement parameters, the time of feeding back the measurement parameters, or the intervals therebetween are referred to as time information related to the first signaling. The reason for calling it time information related to the first signaling is that the time of enabling the first signaling can be determined based on an agreed-upon offset between the time of transmitting the first signaling and a communication node, and the agreed-upon offset is related to the maximum time it takes for the terminal to receive and decode the signaling. The time of transmitting measurement resources, the time of measuring the measurement parameters, and the time of feeding back the measurement parameters determine whether the terminal is in time to acquire the measurement parameters using a new measurement type (e.g., a new AI network) before or after the first signaling is enabled. In one example, the transmission timeslot of the first signaling (e.g., MAC CE) is n, the timeslot transmitting the measurement resource CSI-RS is n+n0, the activation timeslot of the first signaling is n+n1, the timeslot measuring the measurement parameters is n+n2, and the timeslots transmitting the measurement parameters are n+n2 or greater. The measurement parameters include at least one of first-class precoding information, second-class precoding information, CRI, SSBRI, L1-RSRP, L1-SINR, etc. The MAC CE is used to activate measurement type switching between the first measurement type and the second measurement type or to directly indicate that the measurement type is the first measurement type or the second measurement type. Here, n0, n1, and n2 are positive integers. In one example, the first signaling can jointly activate switching of the measurement resource and the measurement type. In one example, the first signaling can jointly activate measurement resources and indicate the measurement type. In one example, the measurement resource is activated or triggered by an independent second signaling, which is higher layer signaling and / or physical layer signaling.

[0042] S204: Determine a measurement type based on time information associated with the first signaling.

[0043] In one embodiment, the terminal may determine the measurement type to be used for measurement based on the transmission timeslot of the first signaling, the transmission timeslot of the measurement resource, and the activation timeslot of the first signaling. For example, the measurement resource CSI-RS is acquired before the first signaling is activated, and the measurement parameters are acquired after the first signaling is activated. The relationship between the time when the first signaling is activated, the time when the measurement resource is transmitted, the time when the measurement parameters are measured, and the time when the measurement parameters are fed back, as well as the terminal's computing capability, determine whether the terminal is in time to acquire the measurement parameters using the new measurement type indicated in the first signaling. If the terminal is in time to acquire the measurement parameters using the new measurement type, it acquires the measurement parameters using the new measurement type; otherwise, it acquires the measurement parameters using the original measurement type or acquires the measurement parameters using a default measurement type. Acquiring the measurement parameters using the default measurement type may include acquiring measurement parameters based on previous first-class precoding information or ignoring the current measurement operation and determining that the measurement parameters are an empty set.

[0044] In one embodiment, the measurement type may include at least one of a first measurement type, a second measurement type, and a third measurement type. The first measurement type is a measurement type used by the terminal before the first signaling is enabled, for example, by acquiring measurement parameters based on an original AI network, an original measurement method, or an original measurement module. The second measurement type is a measurement type used by the terminal after the first signaling is enabled, for example, by acquiring measurement parameters based on an updated AI network, an updated measurement method, or an updated measurement module indicated by the first signaling. The third measurement type is a terminal default measurement type. The terminal default measurement type may be, for example, a measurement type configured in the terminal when shipped from the factory or a measurement type of promised rollback between communication nodes. For example, measurement parameters may be acquired based on a method based on a conventional DFT codebook or feature vector decomposition. The third measurement type may be acquired without performing measurements, and the corresponding third measurement parameters may be an empty set.

[0045] S206: Determine measurement parameters based on the measurement resource and the measurement type.

[0046] In one embodiment, the method determines that the measurement type is a first measurement type, and obtains a first measurement parameter according to the first measurement type, i.e., measures the measurement resource according to a measurement scheme corresponding to the first measurement type to obtain the first measurement parameter; determines that the measurement type is a second measurement type, and obtains a second measurement parameter according to the second measurement type, i.e., measures the measurement resource according to a measurement scheme corresponding to the second measurement type to obtain the second measurement parameter; determines that the measurement type is a third measurement type, and obtains a third measurement parameter according to the third measurement type, i.e., measures the measurement resource according to a measurement scheme corresponding to the third measurement type to obtain the third measurement parameter. In one embodiment, the third measurement parameter may be an empty set.

[0047] In one example, the first signaling takes a first value and instructs the terminal to measure the measurement resource in a manner corresponding to a first measurement type to obtain first measurement parameters, and the first signaling takes a second value and instructs the terminal to measure the measurement resource in a manner corresponding to a second measurement type to obtain second measurement parameters. In one example, the first signaling is used to activate measurement type switching, i.e., if the terminal has enough time after the first signaling is activated, the terminal can obtain measurement parameters using a new measurement type. In one example, if the terminal does not have enough time to obtain measurement parameters using the new measurement type, the terminal obtains measurement parameters using a default measurement type. In one example, if the terminal does not have enough time to obtain measurement parameters using the new measurement type, the terminal obtains measurement parameters using the measurement type used before the first signaling was activated.

[0048] In some examples, the base station transmits measurement resources, where the measurement resources may include at least one set of channel measurement resources and may further include at least one set of interference measurement resources. In one example, the first measurement parameter and the second measurement parameter are second-class precoding matrices and correspond to different neural network parameters and / or models.

[0049] The first measurement parameters and the second measurement parameters correspond to different neural network parameters and / or models. For example, the first measurement parameters are obtained based on a first set of neural network parameter and / or model measurements, and the second measurement parameters are obtained based on a second set of neural network parameter and / or model measurements. Here, the first set of neural network parameters and / or models correspond to the neural network parameters and / or models before the first signaling is enabled. The second set of neural network parameters and / or models correspond to the neural network parameters and / or models after the first signaling is enabled. The first signaling includes a first value and a second value. In some examples, the first value is 0 and the second value is a non-zero value. In some examples, the first value is true and the second value is false. In some examples, the first value is a non-zero value and the second value is 0. In some examples, the first value is false and the second value is true. In some examples, the first signaling is a combination of values of one field or multiple fields.

[0050] S208: The measurement parameters are fed back.

[0051] A measurement parameter feedback method according to an embodiment of the present application receives a first signaling and a measurement resource, determines a measurement type based on time information related to the first signaling, determines measurement parameters based on the measurement resource and the measurement type, and feeds back the measurement parameters, thereby selecting an appropriate measurement type to obtain measurement parameters, and thereby feeding back more accurate measurement parameters.

[0052] In one embodiment, determining a measurement parameter based on the measurement resource and the measurement type includes one of determining that the measurement type is a first measurement type and obtaining a first measurement parameter based on the first measurement type, determining that the measurement type is a second measurement type and obtaining a second measurement parameter based on the second measurement type, or determining that the measurement type is a third measurement type and obtaining a third measurement parameter based on the third measurement type. In one embodiment, the third measurement parameter may be an empty set.

[0053] In one embodiment, the time information includes at least one of a first time, a second time, a third time, and a fourth time; The first time is the time at which the measurement resource is transmitted, for example, slotn+n0 in FIG. The second time is the time when the first signaling is enabled, for example, slotn+n1 in FIG. The third time is the time when the measurement parameters are acquired, for example, slot n+n2 in FIG. The fourth time is the time at which the measurement parameters are transmitted.

[0054] In one example, the first time, the second time, the third time, and the fourth time are integers, the first time is smaller than the second time, and the second time is smaller than the third time and / or the fourth time.

[0055] If the difference (n1-n0) between the second time and the first time is less than or equal to a first threshold, the terminal acquires measurement parameters using the updated second measurement type. For example, for a second AI network, the time of transmitting a measurement resource is relatively close to the time of enabling the first signaling, and the terminal may have enough time to acquire measurement parameters using a new measurement type, so the terminal determines that the measurement type is the second measurement type and acquires the second measurement parameters based on the second measurement type. If the difference (n1-n0) between the second time and the first time is greater than a first threshold, the terminal may not have enough time to acquire measurement parameters using a new measurement type, so the terminal determines that the measurement type is the first measurement type and acquires the first measurement parameters based on the first measurement type. If the difference (n1-n0) between the second time and the first time is greater than a first threshold, the terminal determines that the measurement type is the third measurement type and acquires the third measurement parameters based on the third measurement type.

[0056] If the difference (n2-n1) between the third time and the second time is greater than a second threshold, the interval between enabling first signaling and acquiring the measurement parameters is relatively large, so the terminal may have enough time to acquire measurement parameters using a new measurement type, and determines that the measurement type is the second measurement type and acquires second measurement parameters based on the second measurement type. If the difference (n2-n1) between the third time and the second time is equal to or less than a second threshold, the interval between enabling first signaling and acquiring the measurement parameters is relatively small, so the terminal may not have enough time to acquire measurement parameters using a new measurement type, and determines that the measurement type is the third measurement type and acquires third measurement parameters based on the third measurement type. If the difference (n2-n1) between the third time and the second time is equal to or less than a second threshold, the measurement type is determined to be the first measurement type and acquires first measurement parameters based on the first measurement type.

[0057] If the difference (n2-n0) between the third time and the first time is greater than a third threshold, the interval between acquiring the measurement parameters and transmitting the measurement resource is relatively large, so the terminal may have enough time to acquire measurement parameters using a new measurement type, and determines that the measurement type is the second measurement type and acquires the second measurement parameters based on the second measurement type. If the difference (n2-n0) between the third time and the first time is equal to or less than a second threshold, the terminal determines that the measurement type is the third measurement type and acquires the third measurement parameters based on the third measurement type. If the difference (n2-n0) between the third time and the first time is equal to or less than a second threshold, the interval between acquiring the measurement parameters and transmitting the measurement resource is relatively small, so the terminal may not have enough time to acquire measurement parameters using a new measurement type, and determines that the measurement type is the first measurement type and acquires the first measurement parameters based on the first measurement type.

[0058] If the difference between the fourth time and the second time is greater than a fourth threshold, the terminal determines that the measurement type is the second measurement type and acquires second measurement parameters based on the second measurement type. Because the interval between transmitting the measurement parameters and enabling first signaling is relatively large, the terminal may have enough time to acquire measurement parameters using a new measurement type. If the difference between the fourth time and the second time is equal to or less than a fourth threshold, the terminal determines that the measurement type is the third measurement type and acquires third measurement parameters based on the third measurement type. If the difference between the fourth time and the second time is equal to or less than a fourth threshold, the terminal determines that the measurement type is the first measurement type and acquires first measurement parameters based on the first measurement type. Because the interval between transmitting the measurement parameters and enabling first signaling is relatively small, the terminal may not have enough time to acquire measurement parameters using a new measurement type.

[0059] If the fourth time is greater than the third time, the terminal determines that the measurement type is the second measurement type and acquires second measurement parameters based on the second measurement type. Because the interval between transmitting the measurement parameters and acquiring the measurement parameters is relatively large, the terminal may have enough time to acquire measurement parameters using a new measurement type. If the fourth time is equal to or less than the third time, the terminal determines that the measurement type is the third measurement type and acquires third measurement parameters based on the third measurement type. If the fourth time is equal to or less than the third time, the terminal determines that the measurement type is the first measurement type and acquires first measurement parameters based on the first measurement type. Because the interval between transmitting the measurement parameters and acquiring the measurement parameters is relatively small, the terminal may not have enough time to acquire measurement parameters using a new measurement type.

[0060] If the difference between the third time and the second time is greater than the length of the measurement time for measuring the measurement resource, the terminal determines that the measurement type is the second measurement type and acquires second measurement parameters based on the second measurement type. Because the interval between acquiring the measurement parameters and enabling first signaling is relatively large, the terminal may have enough time to acquire measurement parameters using a new measurement type. If the difference between the third time and the second time is equal to or less than the length of the measurement time for measuring the measurement resource, the terminal determines that the measurement type is the third measurement type and acquires third measurement parameters based on the third measurement type. If the difference between the third time and the second time is equal to or less than the length of the measurement time for measuring the measurement resource, the terminal determines that the measurement type is the first measurement type and acquires first measurement parameters based on the first measurement type. Because the interval between acquiring the measurement parameters and enabling first signaling is relatively small, the terminal may not have enough time to acquire measurement parameters using a new measurement type.

[0061] If the third time is greater than the second time and the second time is greater than the first time, it is determined that the measurement type is the third measurement type, and an empty set is obtained based on the third measurement type, that is, no measurement is performed. In other words, when n0 < n1 < n2, the terminal does not perform CSI measurement. In this case, although the base station has already transmitted the first signaling for instructing the update of the measurement type, the terminal may not have enough time to obtain the measurement parameters using the new measurement type, and in this case, it may not be necessary to perform the measurement.

[0062] When the third time is greater than the second time and the second time is greater than the first time, it is determined that the measurement type is the first measurement type, and a first measurement parameter is obtained based on the first measurement type. In other words, when n0 < n1 < n2, the terminal performs CSI measurement. In one embodiment, the first measurement parameter and other measurement parameters are simultaneously transmitted using a transmission resource for feedback of the measurement parameter. However, when the ability to simultaneously transmit the first measurement parameter and other measurement parameters is not available, the priority of transmitting the first measurement parameter using the transmission resource may be decreased, and other measurement parameters may be preferentially transmitted. In this case, the base station has already transmitted the first signaling for instructing the update of the measurement type, but the new measurement type (for example, the second measurement type) has not yet been activated, or the terminal cannot obtain the measurement parameter using the new measurement type in time. In this case, measurement can be performed. However, in one example, when the target measurement type is the first measurement type, the priority of the first measurement parameter may be set to be lower than the priority of other measurement parameters transmitted using the same transmission resource. Other CSI is preferentially transmitted, that is, measurement is performed using the first measurement type corresponding to the first measurement model, but the measurement parameter is not necessarily reported. This is because the channel environment has changed. It is less likely to obtain channel state information using the first measurement model, and if there is a contradiction, it may not be transmitted. However, if the ability to transmit the first measurement parameter is sufficient, it may be reported. In one example, when the transmission resource can simultaneously transmit the first measurement parameter and other CSI, the first measurement parameter and other CSI may be simultaneously transmitted using the transmission resource. In one example, when the transmission resource transmits only the first measurement parameter, the first measurement parameter is transmitted using the transmission resource.

[0063] In another example, when the target measurement type is the third measurement type, the terminal may report measurement parameters. The terminal acquires third measurement parameters corresponding to the third measurement type based on measurement resources, and the third measurement parameters are first-class precoding information. In one embodiment, the number of bits corresponding to the third measurement parameters is equal to or less than the number of bits corresponding to the first measurement parameters, or the number of bits corresponding to the third measurement parameters is equal to or less than the effective transmission bits of the corresponding transmission resource, or the number of bits corresponding to the second measurement parameters is equal to or less than the number of bits corresponding to the first measurement parameters. This is because the size of the transmission resource is set based on the power size corresponding to the first measurement type. If the number of bits corresponding to the new second or third measurement parameter is greater than the number of bits of the original measurement parameters, the new measurement parameters may not be transmitted effectively.

[0064] In another embodiment, the time information includes at least one of a first interval indicating an interval between transmitting a reference signal resource and enabling the first signaling, a second interval indicating an interval between enabling the first signaling and acquiring a measurement parameter, a third interval indicating an interval between transmitting a reference signal resource and feeding back a measurement parameter, and a fourth interval indicating an interval between enabling the first signaling and transmitting the measurement parameter. In other words, the first interval is determined based on a first time and a second time, the second interval is determined based on a second time and a third time, the third interval is determined based on the first time and a third time, and the fourth interval is determined based on the second time and a fourth time.

[0065] In one embodiment, if the first interval is equal to or less than a first threshold, the measurement type is determined to be a second measurement type, and second measurement parameters are acquired based on the second measurement type. If the first interval is greater than a first threshold, the measurement type is determined to be a third measurement type, and third measurement parameters are acquired based on the third measurement type. If the first interval is greater than a first threshold, the measurement type may be the first measurement type, and first measurement parameters are acquired based on the first measurement type. This is because the interval between transmitting a reference signal resource and enabling the first signaling is relatively long, and the terminal may have enough time to acquire measurement parameters using a new measurement type, or conversely, the terminal may not have enough time to acquire measurement parameters using the new measurement type.

[0066] If the second interval is greater than a second threshold, the terminal determines that the measurement type is a second measurement type and acquires second measurement parameters based on the second measurement type; if the second interval is equal to or less than the second threshold, the terminal determines that the measurement type is a third measurement type and acquires third measurement parameters based on the third measurement type. If the second interval is equal to or less than the second threshold, the measurement type may be a first measurement type and acquire first measurement parameters based on the first measurement type. This is because the interval between enabling first signaling and acquiring measurement parameters is relatively large, and the terminal may have enough time to acquire measurement parameters using a new measurement type, or conversely, the terminal may not have enough time to acquire measurement parameters using the new measurement type.

[0067] If the third interval is greater than a third threshold, determine that the measurement type is a second measurement type and acquire second measurement parameters based on the second measurement type; if the third interval is equal to or less than a third threshold, determine that the measurement type is a third measurement type and acquire third measurement parameters based on the third measurement type. If the third interval is equal to or less than a third threshold, the measurement type may be a first measurement type and acquire first measurement parameters based on the first measurement type. This is because the interval between transmitting a reference signal resource and feeding back measurement parameters is relatively long, and the terminal may have enough time to acquire measurement parameters using a new measurement type, but conversely, the terminal may not have enough time to acquire measurement parameters using the new measurement type.

[0068] If the fourth interval is greater than a fourth threshold, the terminal determines that the measurement type is a second measurement type and acquires second measurement parameters based on the second measurement type; if the fourth interval is equal to or less than the fourth threshold, the terminal determines that the measurement type is a third measurement type and acquires third measurement parameters based on the third measurement type; if the fourth interval is equal to or less than the fourth threshold, the measurement type may be a first measurement type and acquire first measurement parameters based on the first measurement type. This is because the interval between enabling the first signaling and transmitting the measurement parameters is relatively long, and the terminal may have enough time to acquire measurement parameters using the new measurement type, or conversely, the terminal may not have enough time to acquire measurement parameters using the new measurement type.

[0069] If the second interval is smaller than the fourth interval, the measurement type is determined to be a second measurement type, and a second measurement parameter is obtained based on the second measurement type. If the second interval is equal to or greater than the fourth interval, the measurement type is determined to be a third measurement type, and a third measurement parameter is obtained based on the third measurement type. If the second interval is equal to or smaller than the fourth interval, the measurement type may be a first measurement type, and a first measurement parameter is obtained based on the first measurement type.

[0070] If the second interval is less than or equal to the length of the measurement time for measuring the measurement resource, the measurement type is determined to be a second measurement type, and second measurement parameters are obtained based on the second measurement type. If the second interval is greater than the length of the measurement time for measuring the measurement resource, the measurement type is determined to be a third measurement type, and third measurement parameters are obtained based on the third measurement type. If the second interval is greater than the length of the measurement time for measuring the measurement resource, the measurement type may be a first measurement type, and first measurement parameters are obtained based on the first measurement type.

[0071] In one embodiment, the length of the measurement time for measuring the measurement resource is determined based on Z and an offset Δt, for example, Z+offset Δt, where Z is the distance from the last symbol of a transmission resource that transmits the measurement resource to the first symbol of a transmission resource that feeds back the measurement parameter, and the offset may be determined according to the measurement type, for example, the offset for the first measurement type and the second measurement type is greater than 0, and for the default conventional codebook-based method, the offset may be 0. In one example, the offset may be set by the base station.

[0072] When the second interval is greater than the first interval, it is determined that the measurement type is the third measurement type, and an empty set is obtained based on the third measurement type. In one embodiment, when the first interval is greater than 0 and the second interval is greater than 0, no measurement is performed. In other words, when n0 < n1 < n2, the terminal does not perform CSI measurement. In this case, the base station has already transmitted the first signaling for instructing the update of the measurement type, but the new measurement type, i.e., the second measurement type (e.g., a new AI network or a new measurement method or a new measurement module), has not been activated yet, or the terminal does not have enough time to obtain the measurement parameters using the new measurement type. In this case, no measurement is performed.

[0073] When the first interval is greater than 0 and the second interval is greater than 0, the target measurement type is the first measurement type or the third measurement type. In other words, when n0 < n1 < n2, the terminal performs CSI measurement. After the measurement, in one embodiment, the first measurement parameter and other measurement parameters are simultaneously transmitted using the transmission resource for feedback of the measurement parameters. However, when the ability to simultaneously transmit the first measurement parameter and other measurement parameters is not available, the priority of transmitting the first measurement parameter using the transmission resource may be decreased, and other measurement parameters may be preferentially transmitted.

[0074] In this case, the base station may transmit the first signaling for instructing a measurement model update, but the new measurement type, the second measurement type, may not be enabled yet or may not be available in time for the terminal to acquire measurement parameters using the new measurement type. However, in one embodiment, if the target measurement type is the first measurement type, the priority of the first measurement parameter may be set to be lower than the priority of other measurement parameters transmitted on the same transmission resource. Other CSI may be preferentially transmitted, i.e., measured using the first measurement type corresponding to the first measurement model, but the measurement parameters may not necessarily be reported. This is because the channel environment has changed, and it is unlikely that channel state information will be acquired using the first measurement model. If there is a contradiction, the measurement parameters may not be transmitted, but may be reported if there is sufficient capacity to transmit the first measurement parameters. In one example, if the transmission resource can simultaneously transmit the first measurement parameters and other CSI, the first measurement parameters and other CSI may be simultaneously transmitted on the transmission resource. In one example, if the transmission resource transmits only the first measurement parameters, the first measurement parameters are transmitted on the transmission resource.

[0075] In another embodiment, when the target measurement type is the third measurement type, the terminal may report measurement parameters. The terminal acquires third measurement parameters corresponding to the third measurement type based on measurement resources, and the third measurement parameters are first-class precoding information. In one embodiment, the number of bits corresponding to the third measurement parameters is equal to or less than the number of bits corresponding to the first measurement parameters, or the number of bits corresponding to the third measurement parameters is equal to or less than the effective transmission bits of the corresponding transmission resource, or the number of bits corresponding to the second measurement parameters is equal to or less than the number of bits corresponding to the first measurement parameters. This is because the size of the transmission resource is set based on the power size corresponding to the first measurement type. If the number of bits corresponding to the new second or third measurement parameter is greater than the number of bits of the original measurement parameters, the new measurement parameters may not be transmitted effectively.

[0076] If the target measurement type is the first measurement type, the measurement resource is measured based on the first measurement type to obtain the first measurement parameter, where the first measurement parameter is second-class precoding information. If the target measurement type is the second measurement type, the measurement resource is measured based on the second measurement type to obtain the second measurement parameter, where the second measurement parameter is second-class precoding information. If the target measurement type is the third measurement type, the measurement resource is measured based on the third measurement type to obtain the third measurement parameter, where the third measurement parameter is first-class precoding information.

[0077] As a result, the measurement parameter feedback method according to one embodiment of the present application measures resources before the first signaling is enabled, but when a new measurement type is updated or measurement is performed after the first signaling is enabled, an appropriate measurement type can be selected according to the processing capability or channel conditions of the terminal to obtain measurement parameters, and more accurate measurement parameters can be fed back.

[0078] 4 is a structural schematic diagram of a measurement parameter feedback device according to an embodiment of the present application. As shown in FIG. 4, the measurement parameter feedback device 400 includes a first receiving module 410, a first determining module 420, a second determining module 430, and a feedback module 440.

[0079] The first receiving module 410 is used to receive the first signaling and the measurement resource, the first determining module 420 is used to determine the measurement type based on the time information associated with the first signaling, the second determining module 430 is used to determine the measurement parameters based on the measurement resource and the measurement type, and the feedback module 440 is used to feed back the measurement parameters.

[0080] In one embodiment, the first signaling is used to process one of indicating a measurement type, activating a measurement type switch, indicating a measurement type and activating a measurement resource, or switching a measurement type and activating a measurement resource, wherein there is a correspondence between the measurement type and the measurement parameters, and the measurement resource includes at least one reference signal resource.

[0081] In one embodiment, the measurement types include at least two of a first measurement type, which is a measurement type used by the terminal before the first signaling is enabled, a second measurement type, which is a measurement type used by the terminal after the first signaling is enabled, and a third measurement type, which is a default measurement type of the terminal.

[0083] In one embodiment, the first measurement parameter is second class precoding information, or the second measurement parameter is second class precoding information, or the third measurement parameter is an empty set, or the third measurement parameter is first class precoding information.

[0084] In one embodiment, the priority of the first measurement parameter is lower than the priority of other measurement parameters transmitted on the same transmission resource.

[0085] In one embodiment, the number of bits corresponding to the third measurement parameter is less than or equal to the number of bits corresponding to the first measurement parameter, or the number of bits corresponding to the third measurement parameter is less than or equal to the effective transmission bits of the corresponding transmission resource, or the number of bits corresponding to the second measurement parameter is less than or equal to the number of bits corresponding to the first measurement parameter.

[0086] In one embodiment, the time information includes at least one of a first time which is the time to transmit the measurement resource, a second time which is the time to enable the first signaling, a third time which is the time to acquire the measurement parameter, and a fourth time which is the time to transmit the measurement parameter, wherein the first time is smaller than the second time, and the second time is smaller than the third time and / or the fourth time.

[0087] In one embodiment, the step of determining a measurement type based on time information related to the first signaling includes one of the steps of: determining that the measurement type is a second measurement type if a difference between the second time and the first time is less than or equal to a first threshold; determining that the measurement type is a first measurement type if a difference between the second time and the first time is greater than a first threshold; and determining that the measurement type is a third measurement type if a difference between the second time and the first time is greater than a first threshold, wherein the second measurement type corresponds to a second measurement parameter, the first measurement type corresponds to a first measurement parameter, and the third measurement type corresponds to a third measurement parameter.

[0088] In one embodiment, the step of determining a measurement type based on time information related to the first signaling includes one of the steps of: determining that the measurement type is a second measurement type if a difference between the third time and the second time is greater than a second threshold; determining that the measurement type is a first measurement type if a difference between the third time and the second time is equal to or less than a second threshold; and determining that the measurement type is a third measurement type if a difference between the third time and the second time is equal to or less than a second threshold, wherein the second measurement type corresponds to a second measurement parameter, the first measurement type corresponds to a first measurement parameter, and the third measurement type corresponds to a third measurement parameter.

[0094] In one embodiment, the time information includes at least one of a first interval for indicating the interval between transmitting a reference signal resource and enabling the first signaling, a second interval for indicating the interval between enabling the first signaling and acquiring measurement parameters, a third interval for indicating the interval between transmitting a reference signal resource and feeding back measurement parameters, and a fourth interval for indicating the interval between enabling the first signaling and transmitting measurement parameters.
