[0038] In order to better understand the technical solutions provided by this application, we first introduce the relevant technologies involved in this application.
[0039] 1. CSI Architecture
[0040] Generally, the CSI architecture can be divided into two parts: downlink CSI and uplink CSI. The downlink CSI architecture includes downlink physical channels and downlink reference signals, while the uplink CSI architecture includes uplink physical channels and uplink reference signals.
[0041] The downlink physical channel is usually used to transmit data, and the downlink reference signal is usually used to perform channel estimation to obtain downlink channel state information (CSI). The uplink physical channel is usually used to transmit uplink data, and the uplink reference signal is usually used to perform channel estimation to obtain uplink channel state information (CSI).
[0042] In 5G systems, CSI is mainly used in adaptive beamforming and multiple input multiple output (MIMO) technologies to improve wireless transmission bandwidth and reliability.
[0043] In general, the 5G CSI architecture is a very important technology in 5G communication systems, playing an important role in improving wireless transmission bandwidth and reliability and interference coordination.
[0044] 2. CSI Report Content
[0045] Typically, the terminal may determine through higher layer signaling or default rules that the CSI report may include one of: 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR' or 'cri-RI-LI-PMI-CQI'.
[0046] If the terminal is configured with CSI-ReportConfig and the upper-layer parameter reportQuantity is set to "none", the terminal will not report anything for CSI-ReportConfig.
[0047] If the reportQuantity field in the high-level parameter CSI-ReportConfig is set to 'cri-RI-CQI', the terminal assumes that the precoding matrix indicator (PMI) is a unit matrix and only needs to report the CSI reference signal (CSI-RS) resource indicator (CSI-RS Resource Indicator, CRI), rank indicator (RI) and channel quality indicator (CQI), without reporting PMI.
[0048] For the Type 2 series CSI reports carried on the Physical Uplink Shared Channel (PUSCH), they are usually divided into two parts, CSI report part 1 and CSI report part 2. Each part is independently encoded, and the size of CSI report part 2 can be determined by CSI report part 1.
[0049] 3. Interference measurement reference signal configuration
[0050] In related technologies, one possible implementation scheme is that the network-side device can configure two types of interference measurement reference signal configurations. The first type is associated with at least one CSI interference measurement (IM) resource, which is typically used to measure inter-cell interference power. For single transmission and reception point (STRP) measurement, the number of CSI-IM resources is usually equal to the number of channel measurement reference signals (CSI-RS for channel measurement). For multi-transmission and reception point (MTRP) CSI measurement, there may be one CSI-IM resource corresponding to multiple channel measurement reference signals (CSI-RS for channel measurement). The second type is to associate at least one non-zero power (NZP) CSI reference signal (CSI-RS) for interference measurement. In this case, for each CSI-RS port, the terminal assumes an interfering transmission layer, and the terminal further calculates the channel quality indicator (CQI) based on the interference measured by all CSI-RS ports.
[0051] When the terminal obtains the CQI, the interference obtained is the sum of the interferences obtained based on the two interference measurement reference signal configurations. It can be understood that the terminal obtains the CQI based on the sum of the inter-cell interference and the inter-user interference.
[0052] However, in the above possible interference measurement, the terminal assumes that each interference measurement reference signal port is an interference transmission layer, which cannot support the terminal to perform interference selection, and the network side device needs to send a precoded interference measurement reference signal so that each interference measurement reference signal port corresponds to a transmission layer, making the interference measurement not flexible enough.
[0053] To address the above issues, an embodiment of the present application provides an interference measurement solution.
[0054] The interference measurement solution provided in the embodiments of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.
[0055] FIG2 illustrates a flow chart of an interference measurement method according to an embodiment of the present application. Method 200 may be executed by a terminal. In other words, the method may be executed by software or hardware installed on a communication device. As shown in FIG2 , the method may include the following steps.
[0056] S210: The terminal obtains at least one interference measurement hypothesis.
[0057] In this embodiment of the present application, the at least one interference measurement hypothesis includes a first interference measurement hypothesis, the first interference measurement hypothesis is associated with at least one interference measurement reference signal, each interference measurement reference signal is associated with N interference transmission layers, where N is an integer greater than 0. In this embodiment of the present application, the at least one interference measurement hypothesis may be at least one interference measurement hypothesis configured by a network-side device, or may be at least one interference measurement hypothesis activated by a network-side device. For example, the network-side device or protocol may pre-configure multiple interference measurement hypotheses, and the network-side device may activate at least one of the interference measurement hypotheses through signaling.
[0058] In an optional implementation, the terminal may determine the value of N based on first network signaling sent by a network-side device, or the terminal may determine the value of N based on a rule agreed upon in a protocol, or the terminal may determine the value of N based on its own implementation. In other words, N may be determined based on network signaling, based on a rule agreed upon in a protocol, or based on measurement results. Optionally, when N is determined by the terminal, the terminal may indicate the value of N to the network.
[0059] In an optional implementation, the terminal may also determine whether to feed back precoding matrices associated with N interfering transmission layers based on second network signaling sent by the network-side device.
[0060] In an embodiment of the present application, an interference measurement hypothesis can be understood as an interference measurement method, and different interference measurement hypotheses can be understood as different interference measurement methods. For example, the interference measurement method may be one of the following: one interference measurement method is that the terminal assumes that each reference signal port of the NZP CSI-RS used for interference measurement is associated with an interference transmission layer; another measurement method is that the terminal assumes that after obtaining the precoding matrix through the reference signal port of the NZP CSI-RS, it further performs interference measurement based on the precoding matrix and the estimated channel; another measurement method is that the terminal assumes that some of the reference signal ports of the NZP CSI-RS are associated with a transmission layer, and for other reference signal ports, the terminal first obtains the PMI, and then measures the interference based on the obtained PMI; another measurement method is that the terminal assumes that the port power of each reference signal port of the NZP CSI-RS is the interference power. Therefore, in an embodiment of the present application, the network side device can flexibly configure multiple interference measurement hypotheses to allow the terminal to perform interference measurement, which increases the flexibility of interference measurement.
[0061] The above different measurement methods may also be referred to as an interference measurement hypothesis type.
[0062] In the embodiments of the present application, an interference measurement hypothesis can also be understood as an interference type, and different interference measurement hypotheses can be understood as different interference types. For example, the interference measurement type may be at least one of the following: inter-cell interference, inter-user interference, and uplink and downlink interference. Therefore, the network-side device can flexibly configure multiple interference measurement hypotheses for the terminal to perform interference measurement, increasing the flexibility of interference measurement.
[0063] In an embodiment of the present application, each interference measurement reference signal in at least one interference measurement reference signal associated with the first interference measurement hypothesis is associated with N interference transmission layers. One understanding of each interference measurement reference signal being associated with N interference transmission layers can be: each interference measurement reference signal port of an interference measurement reference signal is not associated with one interference transmission layer, that is, there are at least some interference measurement reference signal ports among the multiple interference measurement signal ports of an interference measurement reference signal, and the terminal cannot assume that the interference measurement reference signal port is associated with one transmission layer. Another understanding can be understood as: each interference measurement reference signal port of an interference measurement reference signal is associated with one transmission layer. Therefore, the network-side device can also flexibly configure the reference signal associated with the first interference measurement hypothesis, thereby increasing the flexibility of interference measurement.
[0064] S212: The terminal performs interference measurement based on the at least one interference measurement hypothesis.
[0065] In an embodiment of the present application, in an optional implementation, for the at least one interference measurement hypothesis obtained, the terminal may determine whether to measure each interference measurement hypothesis based on its implementation. In another optional implementation, for the at least one interference measurement hypothesis obtained, the terminal may determine the interference measurement hypothesis to be measured based on a network signaling instruction. In yet another optional implementation, for the at least one interference measurement hypothesis obtained, the terminal may measure all interference measurement hypotheses. That is, the terminal may measure all interference measurement hypotheses in the at least one interference measurement hypothesis, or may measure some of the interference measurement hypotheses, which is not limited in the embodiments of the present application.
[0066] In an optional implementation, before the terminal performs interference measurement based on the at least one interference measurement hypothesis, the method may further include at least one of the following:
[0067] 1) The terminal determines the interference measurement hypothesis measured by the terminal based on network high-layer signaling;
[0068] 2) The terminal obtains the at least one interference measurement hypothesis based on network high-layer signaling;
[0069] 3) The terminal determines the number of interference measurement hypotheses measured by the terminal based on network high-layer signaling;
[0070] 4) The terminal determines the interference measurement resources associated with each interference measurement hypothesis based on network high-layer signaling or protocol agreement.
[0071] For example, the network-side device may configure multiple interference measurement hypotheses through high-layer signaling, and each interference measurement hypothesis may be associated with at least one interference measurement reference signal.
[0072] Optionally, the terminal may feed back the types of interference hypotheses that the terminal supports measuring, or the terminal may feed back the number of interference hypotheses that the terminal supports measuring.
[0073] Optionally, the protocol may stipulate the number or type of interference measurement hypotheses that can be configured by the network side device under the first condition, or the terminal feedbacks the number or type of interference measurement hypotheses that can be configured by the network side device under the first condition, wherein the first condition is related to at least one of the following:
[0074] 1. Interference measurement bandwidth;
[0075] 2. Number of interference measurement ports;
[0076] 3. Number of interference measurement resources;
[0077] 4. Channel measurement bandwidth;
[0078] 5. Number of channel measurement ports;
[0079] 6. Number of channel measurement resources;
[0080] 7. Measurement type, including: periodic or non-periodic or semi-continuous.
[0081] For example, the first condition may be that the number of interference measurement resources is greater than a first number, where the first number is an integer agreed upon in a protocol. Optionally, the terminal does not expect the network-side device to configure more than two interference measurement hypotheses.
[0082] The channel measurement can be understood as useful signal measurement, corresponding to interference measurement.
[0083] In this embodiment of the present application, a terminal can measure at least one interference measurement hypothesis, wherein a first interference measurement hypothesis of the at least one interference measurement hypothesis is associated with at least one interference measurement reference signal. This allows network-side devices to flexibly configure multiple interference measurement hypotheses, facilitate more accurate acquisition of interference conditions, and further improve system transmission performance.
[0084] In an embodiment of the present application, the first interference measurement hypothesis in the at least one interference measurement hypothesis is associated with at least one interference measurement reference signal, and the terminal assumes that each of the interference measurement reference signals is associated with N interference transmission layers. Optionally, N can be a positive integer less than or equal to the number of ports of the interference measurement reference signal. Optionally, N can be determined according to network signaling or determined according to protocol rules or determined by the terminal according to measurement results. Optionally, the terminal can assume that each interference measurement reference signal is associated with N interference transmission layers, and the network side device can instruct the terminal to feedback the precoding matrix associated with N interference transmission layers through the second network signaling.
[0085] Optionally, in an embodiment of the present application, the at least one interference measurement hypothesis may also include a second interference measurement hypothesis, at least one interference measurement reference signal associated with the second interference measurement hypothesis, and the terminal assumes that each interference measurement reference signal port is associated with an interference transmission layer.
[0086] Optionally, in an embodiment of the present application, one interference measurement hypothesis among the at least one interference measurement hypothesis may be associated with at least one interference measurement reference signal, and the interference measurement hypothesis may be used to measure neighboring cell interference.
[0087] Alternatively, one interference measurement hypothesis among the at least one interference measurement hypothesis may be associated with at least one interference measurement reference signal, and the interference measurement hypothesis may be used to measure interference within a serving cell.
[0088] Alternatively, one interference measurement hypothesis among the at least one interference measurement hypothesis may be associated with at least one interference measurement reference signal, and the terminal assumes that the received power of each interference measurement reference signal is interference power or noise power.
[0089] In this embodiment of the present application, optionally, at least one interference measurement hypothesis measured by the terminal may be associated with the same reference signal set, or one interference measurement hypothesis may be associated with one reference signal set. Optionally, when one interference measurement hypothesis is associated with one reference signal set, the network-side device may instruct the terminal to feed back precoding matrices associated with N interfering transmission layers through second network signaling, and the second network signaling may be configured in a signaling configuration associated with the reference signal set.
[0090] Optionally, the interference measurement reference signal may be an NZP CSI-RS.
[0091] For example, the network-side device configures two interference measurement assumptions for the terminal. The first measurement assumption is associated with an interference measurement reference signal set. The terminal assumes that each interference measurement reference signal port in the interference measurement reference signal set is associated with an interference transmission layer. The second measurement assumption is associated with another interference measurement reference signal set. The terminal assumes that each interference measurement reference signal in the interference measurement reference signal set is associated with N interference transmission layers, where N is an integer indicated by the network-side device. The terminal obtains the precoding matrices associated with the N interference transmission layers and then further performs interference measurement. Optionally, the two reference signal sets are associated with the same resource configuration signaling.
[0092] For another example, the network side device configures an interference measurement reference signal set including two interference measurement assumptions. The first measurement assumption is associated with part of the interference measurement reference signals in the interference measurement reference signal set. The terminal assumes that each reference signal port of the part of the interference measurement reference signal is associated with an interference transmission layer. The second measurement assumption is associated with another part of the reference signals in the interference measurement reference signal set. The terminal assumes that each interference measurement reference signal in the part of the interference measurement reference signal is associated with N interference transmission layers. After obtaining the precoding matrix associated with the N interference transmission layers, the terminal further performs interference measurement, where N is an integer indicated by the network side device.
[0093] For another example, the network-side device configures three interference measurement assumptions to associate a reference signal set with the terminal. The first measurement assumption is associated with the first part of the reference signal resources of an interference measurement reference signal set, and the terminal assumes that each reference signal port of the interference measurement reference signal associated with this part of the reference signal resources is associated with an interference transmission layer. The second measurement assumption is associated with the second part of the reference signal resources of the interference measurement reference signal set, and the terminal assumes that each interference measurement reference signal in the interference measurement reference signal associated with this part of the reference signal resources is associated with N interference transmission layers. After obtaining the precoding matrix associated with the N interference transmission layers, the terminal further performs interference measurement, where N is an integer indicated by the network-side device. The third measurement assumption is associated with the third part of the reference signal resources of the interference measurement reference signal set, and the terminal assumes that the received power of the interference measurement reference signal associated with this part of the reference signal resources is interference power or noise power.
[0094] In an optional implementation, as shown in FIG3 , S212 may include: S214, the terminal determining or selecting at least some interference measurement reference signals or at least some interference measurement reference signal ports to perform interference measurement. Optionally, the terminal may perform interference measurement based on at least some interference measurement reference signals or at least some interference measurement reference signal ports associated with the at least one interference measurement hypothesis to obtain an interference measurement result, and further optionally, obtain CSI or a CSI report.
[0095] In an optional implementation manner, the terminal may perform interference measurement based on at least one of the following manners 1 and 2:
[0096] Method 1: The terminal selects or determines M1 interference measurement reference signals from at least one interference measurement reference signal associated with the first interference measurement hypothesis, and obtains the interference measurement result based on interference measurement of the M1 interference measurement reference signals, where M1 is an integer greater than 1.
[0097] In method 2, the terminal selects or determines M2 interference measurement reference signal ports from all interference measurement reference signal ports of at least one interference measurement reference signal associated with the first interference measurement hypothesis, and obtains the interference measurement result based on the interference measurement result obtained by performing interference measurement on the M2 interference measurement reference signal ports, where M2 is an integer greater than 1.
[0098] Through the above implementation, the terminal can recommend an interference combination or a scheduling combination to the network side device, so that the network side device can perform more appropriate scheduling, avoid scheduling users and strong interference at the same time, and improve system performance.
[0099] In the above-mentioned method 1, the terminal can optionally determine the value of M1 based on an instruction from the network-side device. For example, the terminal can determine the value of M1 based on network signaling sent by the network-side device, that is, the network-side device can configure the value of M1 through network signaling. Optionally, the terminal can determine the maximum value of M1 based on the network signaling sent by the network-side device, that is, the value of M1 determined by the terminal may be less than the maximum value of M1.
[0100] For example, the network-side device configures M1 through high-layer signaling, and the terminal selects M1 interference measurement reference signals from multiple interference measurement reference signals associated with the first interference measurement hypothesis, and indicates to the network-side device which M1 interference measurement reference signals are selected. Optionally, a criterion for the terminal to select M1 interference measurement reference signals from multiple interference measurement reference signals may be: selecting M1 interference measurement reference signals with the maximum signal-to-noise and interference ratio (SINR) or the maximum CQI or the minimum interference power or the minimum interference measurement reference signal received power (RSRP).
[0101] Optionally, when adopting the above-mentioned method 1, the terminal selecting M1 interference measurement reference signals from multiple interference measurement reference signals associated with the first interference measurement hypothesis may include: the terminal selecting M1 interference measurement reference signals from multiple interference measurement reference signals associated with the first interference measurement hypothesis based on third network signaling. In this optional implementation, the network-side device may control whether the terminal selects M1 interference measurement reference signals through higher-layer signaling. This method facilitates the network-side device to flexibly obtain interference measurement results.
[0102] For example, the network side device configures the terminal to select M1 interference measurement signals in the CSI report setting signaling, or the network side device configures the terminal to select the interference measurement signal in the CSI report setting signaling; or the network side device configures the terminal to select M1 interference measurement signals in the CSI-associated resource setting signaling, or the network side device configures the terminal to select the interference measurement signal in the CSI-associated resource setting.
[0103] Optionally, when adopting the above-mentioned method 1, the method may further include: the terminal obtaining M3 configured by the network-side device, where M3 is used to indicate the minimum value of M1, and the terminal selecting at least M3 interference measurement reference signals from multiple interference measurement reference signals associated with the first interference measurement hypothesis, where M3 is an integer greater than 0. In this optional implementation, the network-side device configures M3 through signaling, indicating that the terminal selects at least M3 interference measurement reference signals to obtain CSI.
[0104] For example, the network side device configures M3 through high-layer signaling, that is, when the terminal selects M1 interference measurement reference signals from multiple interference measurement reference signals, the value of M1 is not less than the value of M3. Optionally, the network side device can indicate or the protocol can agree on a target value, for example, a target modulation and coding scheme (MCS) index (index) or a target CQI. The terminal obtains M1 interference measurement reference signals based on the target value or the first criterion, and indicates to the network side device which M1 interference measurement reference signals are selected. The first criterion can be: maximum SINR or maximum CQI or minimum interference power or minimum interference RSRP, etc.
[0105] In an optional implementation, in the above-mentioned method 1, optionally, the terminal may further feedback first indication information to the network-side device, wherein the first indication information is used to indicate the M1 interference measurement reference signals selected by the terminal. For example, the terminal feeds back one interference measurement reference signal indication to the network-side device to indicate the interference measurement reference signal selected by the terminal, or the terminal feeds back a combination number to the network-side device to indicate the interference measurement reference signal selected by the terminal, or the interference measurement reference signal indication may also be used to determine the value of M1, or the terminal feeds back the value of M1 to the network-side device.
[0106] For example, the network side device configures an interference measurement hypothesis to associate multiple interference measurement reference signals. The terminal selects M1 interference measurement reference signals based on the interference measurement of the multiple interference measurement reference signals to obtain the final interference measurement result, and indicates to the network side device which M1 interference measurement reference signal among the multiple interference measurement reference signals the M1 interference measurement reference signal selected by the terminal is.
[0107] Optionally, the terminal may select or determine M1 interference measurement reference signals from at least one interference measurement reference signal associated with the first interference measurement hypothesis based on a first target value. Optionally, the network side device configuration or protocol agrees on a first target value, for example, a target MCS index or a target CQI. Optionally, the terminal obtains M1 interference measurement reference signals based on the first target value, and indicates to the network side device which M1 interference measurement reference signals are selected. One implementation manner is: the terminal obtains the maximum number of interference measurement reference signals that is not less than the first target value based on the first target value. Another implementation manner is: the terminal obtains the maximum number of interference measurement reference signals that is not greater than the first target value based on the first target value. The type of the first target value may be one of the following: MCS, MCS index, CQI, CQI index, Block Error Rate (BLER), and mutual information. For example: the terminal obtains M1 interference measurement reference signals based on the target MCS, and the MCS obtained by the terminal based on the interference measurement results of the M1 interference measurement signals is not less than the target MCS; for another example: the terminal obtains M1 interference measurement reference signals based on the target CQI, and the CQI obtained by the terminal based on the interference measurement results of the M1 interference measurement signals is not less than the target CQI.
[0108] Optionally, in the above-mentioned manner 1, the method may further include: the terminal selecting or determining M1 interference measurement reference signals from at least one interference measurement reference signal associated with the first interference measurement hypothesis based on a first criterion, and optionally indicating to the network-side device which M1 interference measurement reference signals are selected.

[0109] In one embodiment, in the above-mentioned method 1, that is, when the terminal selects M1 interference measurement reference signals from multiple interference measurement reference signals to obtain the final interference measurement result, the terminal feeds back first indication information to the network side device, wherein the first indication information is used to indicate the M1 interference measurement reference signals selected by the terminal. For example, the terminal may feed back an interference measurement reference signal indication to the network side device to indicate the interference measurement reference signal selected by the terminal. Alternatively, the terminal feeds back the number of interference measurement reference signals and the number of combinations associated with the number to the network side device to indicate the interference measurement reference signal selected by the terminal. Optionally, the terminal may feed back the number of interference measurement reference signals in the first part of the CSI report, and the network side device determines the number of bits occupied by the number of combinations associated with the number through the number of interference measurement reference signals.
[0110] In one embodiment, optionally, in the above-mentioned method 1, that is, the terminal selects M1 interference measurement reference signals from multiple interference measurement reference signals to obtain CSI, the terminal may obtain CSI based on the sum of interference powers associated with the M1 interference measurement reference signals.

In this implementation, the terminal may determine the value of M2 according to the network signaling sent by the network side device, and the network side device configures the value of M2 through signaling. For example, the network configures M2 through high-layer signaling, and the terminal selects M2 interference measurement reference signal ports from all reference signal ports of at least one interference measurement reference signal, and indicates to the network side device which M2 interference measurement reference signal ports are selected.

In this implementation, the network-side device controls whether the terminal selects the M2 interference measurement reference signal ports through higher-layer signaling. This facilitates the network-side device to flexibly obtain interference measurement results.
[0114] For example, the network-side device configures the terminal to select M2 interference measurement reference signal ports in the CSI report setting signaling, or the network configures the terminal to select the interference measurement reference signal port in the CSI report setting signaling; or the network configures the terminal to select M2 interference measurement reference signal ports in the CSI-associated resource setting signaling, or the network configures the terminal to select the interference measurement reference signal port in the CSI-associated resource setting.
[0115] Optionally, in the above-mentioned second method, the method may further include: the terminal obtains M4 configured by the network-side device, wherein the M4 is used to indicate the minimum value of the M2, and the terminal selects at least M4 interference measurement ports from all interference measurement reference signal ports of at least one interference measurement reference signal associated with the first interference measurement hypothesis to obtain the interference measurement result. In this optional implementation method, the network-side device can configure M4 through signaling to instruct the terminal to select at least M4 interference measurement reference signal ports to obtain the interference measurement result. For example, the network-side device configures M4 through high-layer signaling, and the terminal selects no less than M4 interference measurement reference signal ports.

The terminal obtains M2 interference measurement reference signal ports based on the second target value. Optionally, the terminal may indicate to the network side device which M2 interference measurement reference signal ports are selected.
[0117] Optionally, in the above-mentioned second embodiment, the method may further include: the terminal selecting or determining M2 interference measurement reference signal ports from all interference measurement reference signal ports of at least one interference measurement reference signal associated with the first interference measurement hypothesis based on a second criterion. In this optional implementation, the terminal may obtain M2 interference measurement reference signal ports based on the second criterion. Optionally, the terminal may indicate to the network-side device which M2 interference measurement reference signal ports are selected. For example, the second criterion may be: maximum SINR, maximum CQI, minimum interference power, minimum interference RSRP, etc.
[0118] In an optional implementation, in the above-mentioned second embodiment, that is, when the terminal determines or selects M2 interference measurement reference signal ports from all ports of at least one interference measurement reference signal to obtain the interference measurement result, the method may further include: the terminal feeding back second indication information to the network-side device, wherein the second indication information is used to indicate the M2 interference measurement reference signal ports selected by the terminal. For example, the terminal feeds back an interference measurement reference signal port indication to the network-side device, and the interference measurement reference signal port indication is used to determine the value of M2, or to determine the M2 interference measurement reference signal ports selected by the terminal.
[0119] Optionally, the second indication information may be multiple, for example, the terminal feeds back multiple interference measurement reference signal port indications, each interference measurement reference signal port indication is associated with an interference measurement reference signal, that is, the terminal indicates an interference measurement reference signal port selected from an interference measurement reference signal through each interference measurement reference signal port indication. Optionally, the terminal may indicate the number of interference measurement reference signal port indications to the network side device through the first part of the CSI report, or the number of the interference measurement reference signal port indications is equal to the number of interference measurement reference signals associated with the first interference measurement hypothesis.
[0120] Optionally, the second indication information may also be one. For example, the terminal feeds back an interference measurement reference signal port indication, where the interference measurement reference signal port indication is associated with at least one interference measurement reference signal. Optionally, the terminal indicates to the network-side device, through the first part of the CSI report, the number of interference measurement reference signal ports associated with the interference measurement reference signal port indication, or the number of interference measurement reference signal ports associated with the interference measurement reference signal port indication is equal to the number of all interference measurement reference signal ports associated with the first interference measurement hypothesis.
[0121] In an optional implementation, in the above-mentioned method 2, that is, when the terminal selects M2 interference measurement reference signal ports from all ports of at least one interference measurement reference signal to obtain the interference measurement result, the method may also include: the terminal feeds back the value of M2 to the network side device, or the terminal feeds back the number of interference measurement reference signal ports selected for each interference measurement reference signal to the network side device.
[0122] Optionally, the terminal may feed back a combination number to the network-side device, where the combination number is used to determine which of the M2 interference measurement reference signal ports among all interference measurement reference signal ports the M2 interference measurement reference signal ports selected by the terminal are.
[0123] Optionally, the terminal may also feed back multiple combination numbers to the network side device, each combination number being associated with an interference measurement reference signal, and the combination number being used to indicate which ports in the associated interference measurement reference signal the terminal selects to obtain the interference measurement result.
[0124] In an optional implementation, the terminal performing interference measurement based on at least one interference measurement hypothesis may further include at least one of the following:
[0125] 1) For one interference measurement hypothesis among the at least one interference measurement hypothesis, the terminal selects at least one target interference measurement reference signal combination from at least one interference measurement reference signal combination, and obtains the interference measurement result based on the interference measurement result obtained by performing interference measurement on the at least one target interference measurement reference signal combination, wherein the at least one interference measurement reference signal combination is an interference measurement reference signal combination configured or indicated by the network side device for at least one interference measurement reference signal associated with the interference measurement hypothesis; in this implementation manner, the network side device may configure at least one interference measurement reference signal combination for the at least one interference measurement reference signal associated with the interference measurement hypothesis, and the terminal selects at least one interference measurement reference signal combination to obtain the interference measurement result.
[0126] 2) For one interference measurement hypothesis among the at least one interference measurement hypothesis, the terminal selects at least one target interference measurement reference signal port combination from the at least one interference measurement reference signal port combination, and obtains the interference measurement result based on the interference measurement result obtained by performing interference measurement on the at least one target interference measurement reference signal port combination, wherein the at least one interference measurement reference signal port combination is an interference measurement reference signal port combination configured or indicated by the network side device for at least one interference measurement reference signal associated with the interference measurement hypothesis. In this implementation, the network side device can configure at least one interference measurement reference signal port combination for the at least one interference measurement reference signal associated with the interference measurement hypothesis, and the terminal selects at least one interference measurement reference signal port combination to obtain the interference measurement result.
[0127] In the above optional implementation manner, the one interference measurement hypothesis may be the first interference measurement hypothesis, may be the second interference measurement hypothesis, or may be other interference measurement hypothesis among the at least one interference measurement hypothesis.
[0128] In the above optional implementation, the network side device configures multiple interference conditions or multiple groups of interference conditions for the at least one interference measurement reference signal associated with the interference measurement hypothesis. The terminal selects at least one interference condition according to the network instruction or protocol agreement, and further obtains the interference measurement result. In this way, the network side device can more flexibly obtain the interference measurement results under different interference conditions, or the network side device can more accurately obtain the interference condition that is most suitable for the terminal, further improving the transmission performance of the terminal. The multiple interference conditions or multiple groups of interference conditions can be understood as multiple interference combinations or multiple groups of interference combinations, for example: multiple reference signal combinations or multiple reference signal port combinations or multiple reference signal set combinations or multiple reference signal group combinations or multiple reference signal port groups.
[0129] Optionally, the method may further include: the terminal sending third indication information or fourth indication information to the network-side device, where the third indication information is used to indicate at least one interference measurement reference signal combination selected by the terminal, or the fourth indication information is used to indicate at least one interference measurement reference signal port combination selected by the terminal. Optionally, the terminal may indicate the at least one interference measurement reference signal combination or at least one interference measurement reference signal port combination selected by the terminal to the network-side device via a bit sequence in the first part of the CSI report.
[0130] Optionally, the terminal may indicate at least one interference measurement reference signal combination to the network side device, and the combination is associated with K1 interference measurement reference signals. Optionally, the terminal may also indicate an interference measurement reference signal indication to the network side device, which is used to indicate the interference measurement reference signal selected by the terminal from the interference measurement reference signal combination. One possible implementation is: the terminal indicates a bit sequence of length K1 to the network side device, and the interference measurement reference signal associated with the bit with a bit value of 1 in the bit sequence is the interference measurement reference signal selected by the terminal. Another possible implementation is: the terminal indicates a combination number to the network side device, and the combination number can be demapped in a manner agreed upon by the protocol to obtain the interference measurement reference signal selected by the terminal.
[0131] Optionally, the terminal may indicate at least one interference measurement reference signal port combination to the network-side device, where the interference measurement reference signal port combination is associated with K2 interference measurement reference signal ports. Optionally, the terminal may also indicate an interference measurement reference signal port indication to the network-side device, used to indicate an interference measurement reference signal port combination selected by the terminal from the interference measurement reference signal port combination.
[0132] In the above, K1 and K2 are integers greater than or equal to 0.
[0133] In the above optional implementation, the terminal selects at least one interference condition based on network signaling instructions or protocol agreement. Optionally, the network-side device may indicate a target value or the protocol may agree on a target value, such as a target MCS index or a target CQI. The terminal selects at least one interference condition based on the target value. Optionally, the terminal selects at least one interference condition based on a first criterion or a second criterion. The first criterion or the second criterion may be: maximum SINR, maximum CQI, minimum interference power, minimum interference RSRP, etc.
[0134] In an optional implementation, the terminal performing interference measurement based on at least one interference measurement hypothesis may further include at least one of the following:
[0135] 1) The terminal determines the precoding matrix or equivalent channel matrix associated with the N interference transmission layers associated with the first interference measurement hypothesis according to the codebook type indicated by the fifth network signaling, and performs interference measurement based on the precoding matrix or the equivalent channel matrix; for example, the terminal can determine the N interference transmission layers and the precoding matrix associated with the N interference transmission layers based on the codebook type according to the codebook type indicated by the fifth network signaling, determine the interference measurement equivalent channel matrix (precoding matrix multiplied by channel matrix) based on the precoding matrix and the channel matrix associated with the first interference measurement hypothesis, and further obtain CSI based on the equivalent channel matrix associated with the N interference transmission layers.
[0136] 2) The terminal determines the precoding matrix or equivalent channel matrix associated with the N interference transmission layers associated with the first interference measurement hypothesis according to the codebook type agreed upon in the protocol, and performs interference measurement based on the precoding matrix or the equivalent channel matrix. For example, the terminal may determine N interference transmission layers according to the codebook type agreed upon in the protocol, determine the N interference transmission layers and the precoding matrix associated with the N interference transmission layers based on the codebook type, determine the interference measurement equivalent channel matrix (precoding matrix multiplied by channel matrix) based on the precoding matrix and the channel matrix associated with the first interference measurement hypothesis, and further obtain CSI based on the equivalent channel matrix associated with the N interference transmission layers.
[0137] In the above optional implementation, the terminal can determine the codebook type associated with the precoding matrix associated with the N interfering transmission layers based on network signaling instructions or protocol agreements. In this way, the network-side device can flexibly configure the codebook type associated with the interfering transmission layer, thereby obtaining a more accurate interference situation.
[0138] In the above optional implementation, the terminal may also determine the frequency domain granularity associated with the precoding matrices associated with the N interfering transmission layers, that is, whether the precoding matrix is broadband or sub-band, according to network signaling instructions or protocol agreements.
[0139] For example, the network-side device instructs the terminal through high-layer signaling to obtain precoding matrices associated with N interfering transmission layers based on a Type 1 codebook or a Type 2 codebook.
[0140] For another example, the protocol stipulates that the terminal obtains the precoding matrices associated with N interfering transmission layers based on the Type 1 codebook or the Type 2 codebook.
[0141] In an optional implementation, after obtaining the interference measurement result, the terminal may obtain a CSI report that feeds back the interference measurement result, and report the CSI report to a network-side device.
[0142] In an optional implementation, the method may further include: the terminal determining to obtain a CSI report or determining resources occupied by the terminal for performing the interference measurement, wherein the CSI report is associated with a measurement result of the interference measurement performed by the terminal based on the at least one interference measurement hypothesis, for example, the CSI report is used to feedback the interference measurement result of the interference measurement performed based on the at least one interference measurement hypothesis. The terminal has a limited resource pool. Before obtaining the CSI report or obtaining the interference measurement result, the terminal may determine the resources occupied by the CSI report to determine whether the resources in the resource pool are sufficient to obtain the CSI report or obtain the interference measurement result. If not, the terminal may not perform the interference measurement or update the interference measurement result.
[0143] The resource pool may include at least one of the following:
[0144] 1) Available CSI processing unit (CPU) resource pool;
[0145] 2), an activatable reference signal resource pool;
[0146] 3), activatable reference signal port resource pool;
[0147] 4), activatable interference reference signal resource pool;
[0148] 5), activatable interference reference signal port resource pool;
[0149] 6), a pool of CPU resources dedicated to interference measurement is available.
[0150] Optionally, the terminal may determine the resources occupied by obtaining the CSI report or determining the resources occupied by performing the interference measurement based on at least one of the following:
[0151] 1) Number of interference measurement assumptions;
[0152] 2) Interference measurement hypothesis type; different interference measurement hypothesis types may occupy different resources.
[0153] 3) Number of interference measurement reference signals;
[0154] 4) Number of interference measurement reference signal groups;
[0155] 5) the number of interference measurement reference signals associated with the first interference measurement hypothesis;
[0156] 6) the number of interference measurement reference signal groups associated with the first interference measurement hypothesis;
[0157] 7) The number of interference measurement hypotheses associated with the predetermined codebook; wherein different codebook types may occupy different resources;
[0158] 8) The number of interference measurement reference signals associated with the interference measurement hypothesis associated with the predetermined codebook. Different codebook types may occupy different resources.
[0159] In the above implementation, the number or size of occupied resources determined by the terminal is related to at least one of 1) to 8) above. For example, the terminal determines that the number of CPUs occupied by the interference measurement is a specific multiple of the number of interference measurement hypotheses. For another example, the terminal determines that the number of CPUs occupied by the interference measurement is a specific multiple of the number of reference signals associated with the interference measurement hypothesis associated with the Type 2 codebook.
[0160] The predetermined codebook may be a codebook type configured separately by the network side device for the first interference measurement hypothesis, or may be a codebook type stipulated by the protocol as a signal measurement hypothesis or a channel measurement hypothesis.
[0161] By determining resources in the above manner, the network-side device can more effectively utilize the resources available to the terminal to obtain CSI or perform interference measurement, and try to avoid the situation where the network triggers an interference measurement or CSI measurement, and the terminal cannot complete the measurement due to insufficient available resources.
[0162] In an optional implementation, as shown in FIG4 , after the terminal performs interference measurement based on the at least one interference measurement hypothesis, the method may further include:
[0163] S216: The terminal obtains CQIs associated with the plurality of interference measurement hypotheses based on the interference measurement result obtained by performing the interference measurement;
[0164] S218: The terminal feeds back the acquired CQI to the network side device.
[0165] For example, the terminal may feed back the acquired CQI to the network side device via a CSI report, wherein the CSI report for feeding back the CQI and the CSI report for feeding back the interference measurement result may be the same CSI report.
[0166] In the above implementation, optionally, S216 may include at least one of the following:
[0167] 1) For each interference measurement hypothesis, the terminal obtains a CQI based on an interference measurement result obtained by performing interference measurement on the interference measurement hypothesis.
[0168] In this embodiment, for each interference measurement hypothesis, the terminal obtains CQI respectively and indicates it to the network. In this way, the network side device can obtain more CQI information, thereby achieving more reasonable scheduling and improving user transmission efficiency.
[0169] For example, the network device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis measures inter-cell interference, the second interference measurement hypothesis measures inter-user interference, and the third interference measurement hypothesis measures both inter-cell interference and inter-user interference. The terminal obtains a CQI for each interference measurement hypothesis.
[0170] For another example, the network side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis associates one transmission layer for each interference measurement reference signal port, and the second interference measurement hypothesis associates N interference transmission layers for each interference measurement reference signal. The terminal obtains CQI for each interference measurement hypothesis respectively.
[0171] 2) For each of the first interference measurement hypotheses, the terminal obtains a CQI based on interference measurement results obtained by performing interference measurement on the first interference measurement hypothesis.
[0172] In this embodiment, for each first interference measurement hypothesis, the terminal obtains the CQI respectively and indicates it to the network. In this way, the network-side device can obtain more CQI information associated with the first interference measurement hypothesis, thereby achieving more reasonable scheduling and improving user transmission efficiency.
[0173] 3) The terminal determines at least one interference measurement hypothesis shared CQI based on an instruction of the sixth network signaling.
[0174] In this embodiment, the terminal can determine to obtain a CQI for at least one interference measurement hypothesis based on network signaling; in this way, the network side device configures the terminal to obtain a CQI for multiple interference measurement hypotheses, achieving more flexible CQI acquisition and saving CQI indication overhead.
[0175] For example, the network-side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis measures inter-cell interference, and the second interference measurement hypothesis measures inter-user interference. The network can instruct the terminal through signaling to associate the two interference measurement hypotheses with a CQI. The terminal then sums the interference of the two interference measurement hypotheses to obtain the CQI.
[0176] 4) The terminal determines at least one first interference measurement hypothesis shared CQI based on an instruction of the seventh network signaling.
[0177] In this implementation, the terminal can determine to obtain a CQI for at least one first interference measurement hypothesis based on network signaling; in this way, the network side device can configure the terminal to obtain a CQI for multiple first interference measurement hypotheses, thereby achieving more flexible CQI acquisition and saving CQI indication overhead.
[0178] 5) The terminal determines part of the interference measurement hypothesis in the at least one interference measurement hypothesis based on an instruction of the eighth network signaling, and obtains the CQI based on an interference measurement result obtained by performing interference measurement on the part of the interference measurement hypothesis.
[0179] In this embodiment, the terminal determines the partial interference measurement hypothesis based on network signaling and indicates the CQI to the network side device; in this way, the network side device can flexibly configure the terminal to obtain CQI for the partial interference measurement hypothesis, saving CQI indication overhead.
[0180] For example, the network side device configures multiple interference measurement hypotheses for the terminal. For one of the interference measurement hypotheses, the network side device configures a target CQI or a target MCS. For this interference measurement hypothesis, the terminal does not need to feedback CQI, or for this interference measurement hypothesis, the network side device can indicate that the terminal does not need to feedback CQI.
[0181] In S216, optionally, when the network side device configures a reference CQI, for a reference interference measurement hypothesis in the at least one interference measurement hypothesis, the terminal obtains, based on the measurement result, a difference between the CQI of the reference interference measurement hypothesis and the reference CQI, and uses the difference as the CQI to be fed back for the reference interference measurement hypothesis, wherein the reference interference measurement hypothesis is an interference measurement hypothesis for which the network side device is configured with a reference CQI. In this way, the CQI feedback overhead can be effectively reduced.
[0182] For example, the network-side device configures multiple interference measurement hypotheses for the terminal. For one of the interference measurement hypotheses, the network-side device configures a target CQI (i.e., a reference CQI). For this interference measurement hypothesis, the terminal does not need to feedback the absolute CQI, but instead feeds back the CQI offset of the absolute CQI relative to the target CQI. In this way, the CQI feedback overhead can be reduced.
[0183] In an optional implementation, the method may further include: when there are multiple CQIs fed back, the terminal determining a priority of each of the CQIs, wherein the priority of each CQI is determined by one of the following:
[0184] 1) The configuration order of the CQI-associated interference measurement reference signals.
[0185] In this embodiment, when the terminal feeds back CQIs of multiple interference measurement hypotheses, the priorities of the multiple CQIs are related to the configuration order of the interference measurement reference signals, that is, each interference measurement hypothesis determines the earliest configured target interference measurement reference signal among at least one interference measurement reference signal associated therewith, and among the multiple interference measurement hypotheses, the earliest configured second interference measurement reference signal among the earliest configured target interference measurement reference signals associated therewith has a higher priority than the second earliest configured second interference measurement reference signal, which is higher than the third earliest, and so on.
[0186] For example, the network-side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis associates a transmission layer for each interference measurement reference signal port, and associates the first configured reference signal and the second configured reference signal. The second interference measurement hypothesis associates N interference transmission layers for each interference measurement reference signal, and associates the third configured reference signal and the fourth configured reference signal. The terminal obtains the CQI for each interference measurement hypothesis respectively. When the terminal feeds back the CQI, since the earliest configured reference signal associated with the first interference measurement hypothesis is the first reference signal, and the earliest configured reference signal associated with the second interference measurement hypothesis is the third reference signal, the priority of the CQI associated with the first interference measurement hypothesis is higher than the CQI associated with the second interference measurement hypothesis, that is, it is preferentially mapped to the uplink channel resources.
[0187] 2) The configuration order of the CQI-associated interference measurement hypothesis.
[0188] In this embodiment, when the terminal feeds back CQIs of multiple interference measurement hypotheses, the priorities of the multiple CQIs are related to the order in which the interference measurement hypotheses are configured by the network side device, that is, the terminal determines the priority of the CQI according to the order in which the interference measurement hypotheses are configured.
[0189] For example, the network configures two interference measurement hypotheses for the terminal, and the terminal obtains a CQI for each interference measurement hypothesis. When the terminal feeds back the CQI, the CQI associated with the first interference measurement hypothesis has a higher priority than the CQI associated with the second interference measurement hypothesis, that is, it is preferentially mapped to the uplink channel resources.
[0190] Through the technical solution provided in the embodiments of the present application, the terminal can perform interference measurement based on at least one interference measurement hypothesis. Therefore, the network side equipment can flexibly configure multiple interference measurement hypotheses, thereby enabling the terminal to obtain more accurate interference conditions and improve system transmission performance.

[0195] In the embodiment of the present application, the first interference measurement hypothesis and the second interference measurement hypothesis may be the same interference measurement hypothesis or different interference measurement hypotheses, which is not limited in the embodiment of the present application.
