For example, the terminal can measure a reference signal sent by a network side device according to reference signal configuration information configured by the network side device to obtain a measurement result.

[0038] The first information includes at least one of: first interference information predicted by the terminal based on the measurement result; and channel state information predicted by the terminal based on the measurement result.

[0039] In the embodiments of the present application, the terminal can predict first interference information or channel state information according to a measurement result obtained by measuring a reference signal, and report the predicted first interference information or channel state information to a network side device.

[0040] In the embodiments of the present application, the first interference information or channel state information included in the first information is interference information or channel state information at a second time point, and the second time point is later than a first time point, and the first time point is a time point at which the reference signal is measured.

[0044] By the scheme provided in the embodiments of the present application, a terminal obtains a measurement result by measuring a reference signal; and the terminal reports first information to a network side device based on the measurement result, wherein the first information comprises at least one of: first interference information predicted by the terminal based on the measurement result; and channel state information predicted by the terminal based on the measurement result. Thus, the network side device can obtain interference information or channel state information, and can further perform interference coordination according to the interference information or the channel state information, thereby improving the accuracy of interference coordination.

[0045] In an optional implementation of the embodiments of the present application, the first information further comprises first indication information, and the first indication information is used to indicate at least one of:

[0046] 1) The terminal indicates to the network side device that the first interference information in the reported first information is predicted first interference information; and the network side device can perform inter-cell interference management based on the first interference information reported by the terminal.

[0047] 2) The terminal indicates to the network side device that the channel state information in the reported first information is predicted channel state information.

[0048] In the above implementation, in order to be compatible, the terminal can include the first indication information in the first information to indicate to the network side device that the reported information is predicted information, so that the network side device can know that the information reported by the terminal is predicted interference information or predicted channel state information. For a terminal without prediction capability, a report without the first indication information or carrying the first indication information indicating that the reported information is historical interference information or historical channel state information can be reported to the network side device.

[0049] In an optional implementation, the reference signal in S210 can comprise at least one interference measurement reference signal, and the first interference information can comprise at least one of:

[0050] 1) An interference measurement reference signal ID, by which the interference measurement reference signal associated with the first information reported to the network side device can be reported.

[0051] 2) Measurement information of the interference measurement reference signal, by which the result obtained by measuring the interference measurement reference signal can be reported to the network side device.

[0052] 3) Beam information of a cell associated with the measurement information of the interference measurement reference signal; for example, the beam information can comprise a beam ID and a beam direction, by which the network side device can know the beam associated with the measurement information reported by the terminal.

[0053] 4) a first timestamp information associated with the measurement information of the interference measurement reference signal; the first timestamp information can indicate a time, i.e., the reported measurement information of the interference measurement reference signal is the measurement information at a certain time in the future. Of course, the first timestamp information can also indicate a past time, which is used to indicate the acquisition time of the reported measurement information of the interference measurement reference signal.

[0054] 5) an interference cell identifier; through the interference cell identifier, the network side device can know the cell associated with the interference signal, and then interference coordination between cells can be performed.

[0055] 6) an interference transmit / receive point (TRP) identifier; through the interference TRP identifier, the network side device can know the TRP of the interference terminal, and then interference coordination can be performed.

[0056] 7) a reference signal configuration identifier; through the reference signal configuration identifier, the reference signal configuration associated with the measurement information of the interference measurement reference signal in the first information reported to the network side device can be reported.

[0057] 8) a reference signal resource identifier; the reference signal resource can be further associated with a cell or beam information, and through the reporting of the reference signal resource identifier, the network side device can obtain the cell or beam information associated with the measurement information.

[0058] 9) a reference signal resource set identifier; through the reference signal resource set identifier, the reference signal resource set associated with the measurement information of the interference measurement reference signal in the first information reported to the network side device can be reported, and then the network side device can know the reference signal associated with the measurement information, and the configuration information of the reference signal, such as some configurations for resource set configuration, such as RS period, and the network side device can determine the configuration information of the reference signal associated with the reference signal resource set based on the reference signal resource set identifier reported by the terminal.

[0059] In the above optional implementation, optionally, the measurement information of the interference measurement reference signal includes at least one of the following:

[0060] 1) an interference power level; for example, the interference power level can be a number between 0 and 1 with an interval of 0.1, and the larger the number is, the greater the interference is; a certain number can be associated with an RSRP range or not; or, the interference power level can also be an absolute power dbm or a relative power db.

[0061] 2) a reference signal received power (RSRP);

[0062] 3) Reference Signal Received Quality (RSRQ);

[0063] 4) Precoding matrix indicator (PMI); the interference PMI can be a neighbor PMI, the neighbor PMI is related to the spatial channel characteristics, for example, the neighbor can use a PMI with low correlation to the PMI to reduce interference. The PMI can be a positive PMI and a negative PMI, the positive PMI is to maximize the received power of the interference signal; the negative PMI is to minimize the received power of the interference signal. The network side device can obtain the negative PMI based on the positive PMI. In an implementation mode, the interference cell or the interference signal considers the negative PMI associated with the interference measurement reference signal when using the PMI, which is beneficial to reduce the interference to other cell UEs.

[0064] 5) Channel quality indicator (CQI) of interference;

[0065] 6) Rank indicator (RI) of interference.

[0066] Through the above optional implementation mode, the terminal can report the related measurement information of the interference measurement reference signal to the network side device, so that the network side device can obtain the specific measurement information, and then perform interference management.

[0067] In some embodiments, the above interference PMI reported by the terminal can be an initial PMI obtained based on the measurement result, and in other embodiments, the above interference PMI reported by the terminal can be a compressed PMI. Therefore, in an implementation mode, the interference PMI can be obtained by at least one of the following modes:

[0068] Frequency domain compression mode

[0069] In this mode, the terminal jointly compresses the PMI of multiple subbands of each interference measurement reference signal in a time unit (for example, a time slot) to obtain the interference PMI of the interference measurement reference signal, that is, the interference PMI reported by the terminal. Through the implementation mode, by jointly compressing the PMI of multiple subbands of each interference measurement reference signal in a time unit, the reporting overhead of the terminal can be reduced.

[0070] Wherein, the subband PMI is associated with a subband.

[0071] In the joint compression of the PMI of each interference measurement reference signal in multiple subbands of a time unit (i.e., the PMI obtained by measuring the interference measurement reference signal), when the number of subbands of different interference measurement reference signals is different, the PMI of only the subband part of the multiple interference measurement reference signals can be compressed. Alternatively, the PMI of each interference measurement reference signal can also be compressed according to the maximum number of subbands in the multiple interference measurement reference signals. In this way, for the interference measurement reference signal with a number of subbands less than the maximum number of subbands, the number of subbands of the PMI of the interference measurement reference signal can be supplemented to the maximum number of subbands by padding the tail of the PMI of the interference measurement reference signal with 0. Alternatively, it can be agreed by protocol that the bandwidth part (BWP) configuration and the subband configuration of different interference measurement reference signals are the same, such as configuring the same BWP ID for all interference measurement RSs.

[0072] Time-domain compression mode

[0073] In this mode, the terminal jointly compresses the PMI of each interference measurement signal in multiple continuous time units to obtain the interference PMI. In this implementation, the terminal can compress the PMI (which can be a subband PMI or a wideband PMI) of each interference measurement signal in multiple continuous time units, i.e., compress multiple PMIs obtained in multiple continuous time units.

[0074] Optionally, in the above implementation, the first information can further include time window information associated with the interference measurement reference signal, which indicates to the network side device that the interference PMI reported by the terminal is the PMI compressed in multiple continuous time units corresponding to the time window information.

[0075] In some implementations, the above-mentioned time window information can also be indicated to the terminal by the network side device, i.e., the network side device indicates the terminal to compress the subband or wideband PMI in multiple continuous time units corresponding to the time window information.

[0076] In some implementations, the above-mentioned time window information can also be agreed by protocol.

[0077] Optionally, the time window size indicated by the above-mentioned time window information is the size of the prediction window, i.e., the PMI of the next N slots is predicted, and the subband PMI or wideband PMI of the N slots is compressed.

[0078] Among them, the subband PMI is associated with a subband, and the wideband PMI is associated with the entire BWP.

[0079] Spatial compression mode

[0080] In this mode, the terminal jointly compresses the PMIs (which can be subband PMIs or wideband PMIs) of multiple interference measurement reference signals in a preset time unit to obtain the interference PMI. Through this embodiment, the PMIs of multiple interference measurement reference signals in a certain time unit can be jointly compressed to save the terminal feedback overhead.

[0081] Optionally, in the above embodiment, the terminal can jointly compress the PMIs of multiple interference measurement reference signals in a preset time unit according to an arrangement order of the interference measurement reference signals agreed by a protocol, wherein the first information further includes the interference measurement reference signals associated with the compressed interference PMI. In this optional embodiment, the arrangement order of the interference measurement reference signals agreed by the protocol can be according to a configured order, or according to the size order of the interference measurement reference signal IDs, etc. In addition, the first information can further include the interference measurement reference signals associated with the compressed interference PMI. For example, for a certain interference layer, the PMIs corresponding to a certain subband of a certain slot, M ports and N interference measurement reference signals form a PMI with a dimension of M*N or N*M, and the terminal can report the position (a, b) of the effective element (e.g., greater than a certain threshold, set by the terminal itself) in the M*N matrix and the value corresponding to the position after compression. After receiving the compressed PMI, the network side device can restore the original PMI, and based on the preset arrangement order, can obtain the PMI associated with each interference measurement reference signal.

[0082] In some embodiments, the terminal can further compress and report the interference PMI and the PMI obtained through channel measurement to the network side device

[0083] Optionally, in the specific implementation process, the terminal can use one of the above compression methods for compression, or can use multiple of the above compression methods for compression. For example, the terminal can first use the above frequency domain compression method to jointly compress the PMIs of multiple subbands of each interference measurement reference signal in a time unit (e.g., a slot), and then perform time domain compression on the PMI of each interference measurement reference signal after frequency domain compression, i.e., jointly compress the PMIs of each interference measurement reference signal after frequency domain compression in multiple continuous time units. Alternatively, time domain compression can be performed first, and then frequency domain compression can be performed. Details are not described herein again. Alternatively, the three compression methods described above can be used for compression. For example, the terminal can first use the above frequency domain compression method to jointly compress the PMIs of multiple subbands of each interference measurement reference signal in a time unit (e.g., a slot), and then perform time domain compression on the PMI of each interference measurement reference signal after frequency domain compression, and finally, jointly compress the PMIs of multiple interference measurement reference signals after time and frequency domain compression.

[0084] In some embodiments, the first information can further comprise second indication information, which is used to indicate at least one of the following:

[0085] 1) the interference PMI comprised in the first information is a compressed PMI;

[0086] 2) the compression manner of the interference PMI, i.e. at least one of the above-mentioned frequency domain compression manner, time domain compression manner and spatial domain compression manner.

[0087] Through the above-mentioned implementation manner, the network side device can determine whether the interference PMI in the first information is compressed and which compression manner is adopted if it is compressed, based on the above-mentioned second indication information in the first information.

[0088] It should be noted that the PMI or the interference PMI can be a prediction PMI of an interference measurement reference signal.

[0089] In an optional implementation manner, the reference signal in S210 can comprise a plurality of target reference signal combinations, and the target reference signal combination comprises at least one interference measurement reference signal and one channel measurement reference signal.

[0090] In the above-mentioned optional implementation manner, the channel state information in the first information can comprise at least one of the following:

[0091] 1) a target PMI associated with the target reference signal combination; wherein the target PMI can be a PMI obtained by measuring at least one interference measurement reference signal and channel measurement reference signal in the target reference signal group, and the PMI is obtained by considering interference; optionally, the target PMI can be a PMI predicted based on a measurement result obtained by measuring the target reference signal group by the terminal.

[0092] 2) a target RI associated with the target reference signal combination;

[0093] 3) a target CQI associated with the target reference signal combination.

[0094] Through the above-mentioned optional implementation manner, the terminal can measure the interference measurement reference signal and the channel measurement reference signal based on the reference signal combination configured by the network side device, predict based on the measurement result, and feed back the predicted channel state information to the network side device.

[0095] Optionally, the network side device can configure the length of time of prediction and the time granularity, such as the network side device configuring to predict the CSI of future N slots; the length of time is N, and the time granularity is 1 slot.

[0096] In some embodiments, the terminal can further report second information to the network side device, wherein the second information can include at least one of the following:

[0097] 1) a target reference signal combination ID associated with the channel state information;

[0098] 2) at least one reference signal ID in the target reference signal combination; the reference signal IDs included in the target reference signal combination include a target reference signal ID of a target serving cell and at least one interference measurement reference signal ID

[0099] 3) beam information associated with the channel state information; optionally, the beam information associated with the channel state information can include at least one of the following: beam information of an interference measurement reference signal, beam information of a channel measurement reference signal.

[0100] 4) second timestamp information associated with the channel state information.

[0101] Through the second information, the terminal can report to the network side device which target reference signal group or which reference signal the channel state information in the first information is based on, and the beam information or the second timestamp information associated with the channel state information. The second timestamp information indicates a time including one of the following: past time, time. For example, if the second timestamp information indicates the past time, it indicates the acquisition time of the channel state information reported by the terminal, and if the second timestamp information indicates the time, it indicates the predicted channel state information at a certain time in the future.

[0102] In some embodiments, the above target PMI reported by the terminal can be an initial PMI based on the measurement result, and in other embodiments, the above target PMI reported by the terminal can be a compressed PMI. Therefore, in one embodiment, the target PMI can be obtained by at least one of the following ways:

[0103] Frequency domain compression mode

[0104] In this mode, for each reference signal (including interference measurement reference signal and channel measurement reference signal) in the target reference signal combination, the terminal jointly compresses the sub-band PMIs of the reference signal in a time unit to obtain the target PMI associated with the reference signal.

[0105] In some embodiments, for each reference signal in the target reference signal combination, the terminal can compress the PMI of the sub-band part overlapping with the reference signal in a time unit to obtain the target PMI associated with the reference signal.

[0106] In some embodiments, the terminal jointly compresses the PMI of the reference signal in a plurality of subbands in one time unit according to a maximum number of subbands in the target reference signal combination, and in the case that the number of subbands associated with the reference signal is less than the maximum number of subbands, the terminal fills the tail of the PMI of the reference signal in one time unit with 0.

[0107] In some embodiments, the protocol can agree that the BWP configuration and the subband configuration of different reference signals are the same, for example, when the reference signals are configured, the same BWP ID is configured for all the reference signals.

[0108] Time domain compression mode

[0109] In this compression mode, for each reference signal in the target reference signal combination, the terminal jointly compresses the PMI (which can be subband PMI or wideband PMI) of the reference signal in a plurality of continuous time units to obtain the target PMI of the reference signal.

[0110] Optionally, if the terminal adopts this compression mode, the first information can further include time window information associated with the target PMI, so that the network side device can know the time associated with the target PMI reported by the terminal.

[0111] In some embodiments, the above-mentioned time window information can also be indicated to the terminal by the network side device, that is, the network side device instructs the terminal to compress the subband or wideband PMI in a plurality of continuous time units corresponding to the time window information.

[0112] In some embodiments, the above-mentioned time window information can also be agreed by the protocol.

[0113] Optionally, the time window size indicated by the above-mentioned time window information is the size of the prediction window, that is, the PMI of the next N slots is predicted, and the subband PMI or wideband PMI of the N slots is compressed.

[0114] In the above-mentioned time domain compression mode, the subband PMI is associated with one subband, and the wideband PMI is associated with the entire BWP.

[0115] Spatial domain compression mode

[0116] In this mode, the terminal jointly compresses the PMI of a plurality of reference signals in the target reference signal combination in a preset time unit to obtain the target PMI, so as to save the feedback overhead of the terminal.

[0117] Optionally, in the above embodiment, the terminal jointly compresses the PMIs of the multiple reference signals in the target reference signal combination in a preset time unit according to an arrangement order of reference signals in compression agreed by a protocol, and the first information further comprises a reference signal associated with the compressed PMI. In this optional embodiment, the arrangement order of reference signals in compression agreed by the protocol can be according to a configured order, or according to an order of reference signal IDs, etc. In addition, the first information can further comprise a reference signal associated with the compressed target PMI. For example, for a certain interference layer, a certain subband of a certain slot, the PMI corresponding to M ports and N reference signals, a PMI with a dimension of M*N or N*M is formed, and the terminal can report the position (a, b) of the compressed effective element (e.g., greater than a threshold, set by the terminal itself) in the M*N matrix and the value corresponding to the position. After receiving the compressed PMI, the network side device can restore the original PMI, and based on the preset arrangement order, the PMI associated with each interference measurement reference signal can be obtained.

[0118] Optionally, in the implementation process, the terminal can use one of the above compression methods for compression, or use multiple compression methods for compression. For example, the terminal can first use the above frequency domain compression method to jointly compress the PMIs of each reference signal in multiple subbands in a time unit (e.g., a slot), and then perform time domain compression on the PMI of each reference signal after frequency domain compression, i.e., jointly compress the PMIs of each reference signal in multiple continuous time units after frequency domain compression. Alternatively, time domain compression can be performed first, and then frequency domain compression. Details are not described herein.

In a specific application, the terminal can report the confidence degree and the accuracy information after reporting the first information, or report the confidence degree and the accuracy information before reporting the first information, which is not limited in the embodiments of the present application. Through the channel measurement information of the terminal and the associated confidence degree or accuracy information, the network side device can improve the transmission performance by combining the relevant implementation algorithm. For example, multiple users in the network report interference information and its confidence degree or accuracy, and the network side device can select the interference information with higher confidence degree or accuracy for subsequent interference scheduling or transmission.

[0120] In an optional implementation, the method can further comprise: the terminal receiving third information indicated by the network side device, wherein the third information is used to indicate at least one of the following:

[0121] 1) second interference information of the terminal at least one time unit; the second interference information can be used to supervise the model used for prediction at the terminal side. For example, if the first interference information predicted by the terminal is different from the second interference information indicated by the network side device, it is considered that the prediction result of the terminal model is inaccurate or the model is invalid.

[0122] Optionally, the second interference information can include at least one of the following:

[0130] a reference signal resource identifier;

[0131] a reference signal resource set identifier.

[0132] 2) second interference information at at least one past time; the terminal can combine the interference indicated by the network side device when performing interference prediction. For example, the terminal can predict the first interference information based on the past second interference information indicated by the network side device and the measured interference information.

[0133] 3) scheduling information at at least one past time; the terminal can perform interference measurement based on the scheduling information.

[0134] 4) interference pattern. For example, the third information can indicate an interference pattern, which is used to indicate which time or frequency range or cell the future possible interference occurs, and the terminal can predict the interference on these time or frequency range or cell when performing interference prediction.

[0135] In some embodiments, the above interference pattern can include at least one of the following:

[0136] (1) time domain position of interference;

[0137] (2) frequency domain position of interference;

[0138] (3) spatial position of interference;

[0139] (4) power level of the interference.

[0140] Through the above embodiments, the network side device can inform the terminal of specific information of the interference at a certain time in the future or a certain time in the past, so that the terminal can perform interference measurement or prediction based on the second interference information indicated by the network side device.

[0141] Optionally, the spatial position of the interference comprises at least one of:

[0142] a) at least one interference cell identifier;

[0143] b) at least one reference signal identifier associated with the interference;

[0144] c) reference signal group identifier associated with the interference.

[0145] Through the above spatial position of the interference, the terminal can determine at least one of the cell, the reference signal or the reference signal group corresponding to the interference, and then perform interference measurement or prediction according to the information.

[0146] In an optional implementation, the method can further comprise: reporting, by the terminal to the network side device, at least one of the reference signal identifier and the reference signal group identifier associated with the reference signal measured by the terminal. Through the optional implementation, the network side device can know the reference signal or the reference signal group associated with the reported first information.

In related technologies, if the period of the CMR is different from the period of the IMR, the network side device can configure the channel state information to be obtained based on the CMR and the IMR closest in time to the CMR, or to select which IMR depends on the UE implementation.
