[0036] To better understand the technical solution provided by this application, the related technologies involved in this application will be introduced first.

[0037] 1. CSI architecture

[0038] Generally, the CSI architecture can be divided into two parts: downlink CSI and uplink CSI. Downlink CSI architecture: includes downlink physical channels and downlink reference signals; Uplink CSI architecture: includes uplink physical channels and uplink reference signals.

[0039] Among them, generally, downlink physical channels are used to transmit data, while downlink reference signals are usually used for channel estimation to obtain downlink channel state information (CSI). Uplink physical channels are generally used to transmit uplink data, while uplink reference signals are usually used for channel estimation to obtain uplink channel state information (CSI).

[0040] In the 5G system, CSI is mainly used for Adaptive Beamforming and MIMO (Multiple Input Multiple Output) technologies to improve wireless transmission bandwidth and reliability.

[0041] Generally speaking, the CSI architecture of 5G is a very important technology in the 5G communication system, and it plays an important role in improving wireless transmission bandwidth, reliability, and interference coordination.

[0042] 2. CSI Report Content

[0043] Generally, the terminal can determine through high-layer signaling or default rules that the CSI report can 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'.

[0044] If the terminal is configured with CSI-ReportConfig and the upper-layer parameter reportQuantity is set to "none", then the terminal will not report any content for CSI-ReportConfig.

[0045] If the reportQuantity field in the high-layer parameter CSI-ReportConfig is set to 'cri-RI-CQI', the terminal assumes that the precoding matrix indicator (PMI) is the identity matrix, and only needs to report the CSI reference signal (CSI-RS) resource indicator (CRI), rank indicator (RI), and channel quality indicator (CQI), without reporting the PMI.

[0046] For 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 through CSI report part 1.

[0047] 3. Interference Measurement Reference Signal Configuration

[0048] In the related art, a possible implementation 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 usually used to measure the inter-cell interference power. For single transmission and reception point (STRP) measurements, usually the number of CSI-IM resources is equal to the number of CSI reference signals for channel measurement (CSI-RS for channel measurement). For multi transmission and reception point (MTRP) CSI measurements, there may be one CSI-IM resource corresponding to multiple CSI reference signals for channel measurement (CSI-RS for channel measurement). The second type is associated with 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 one interference transmission layer, and the terminal further calculates the channel quality indicator (CQI) based on the interference measured on all CSI-RS ports.

[0049] During the process of the terminal obtaining the CQI, the interference obtained is the sum of the interferences obtained based on two interference measurement reference signal configurations, which can be understood as the terminal obtaining the CQI based on the sum of the inter-cell interference and the inter-user interference.

[0050] However, in the above possible interference measurements, 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 precoded interference measurement reference signals so that each interference reference signal port corresponds to a transmission layer, making the interference measurement not flexible enough.

[0051] In view of the above problems, an embodiment of the present application provides an interference measurement scheme.

[0052] The following will combine the accompanying drawings and elaborate on the interference measurement scheme provided by the embodiment of the present application through some embodiments and their application scenarios.

[0053] Figure 2 A schematic flowchart of an interference measurement method in an embodiment of the present application is shown. The method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on a communication device. As Figure 2 shown, the method may include the following steps.

[0054] S210, the terminal obtains at least one interference measurement hypothesis.

[0055] In an embodiment of the present application, the at least one interference measurement hypothesis includes a first interference measurement hypothesis, and the first interference measurement hypothesis is associated with at least one interference measurement reference signal. Each of the interference measurement reference signals is associated with N interference transmission layers, where N is an integer greater than 0. In an embodiment of the present application, the at least one interference measurement hypothesis may be at least one interference measurement hypothesis configured by the network-side device, or may be at least one interference measurement hypothesis activated by the 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 them through signaling.

[0056] In an alternative implementation, the terminal may determine the value of N according to the first network signaling sent by the network-side device, or the terminal may also determine the value of N according to the rules agreed upon by the protocol, or the terminal may also determine the value of N according to its own implementation. That is to say, N can be determined according to the network signaling or the rules agreed upon by the protocol or the terminal according to the measurement results. Optionally, when N is determined by the terminal, the terminal may indicate the value of N to the network.

[0057] In an optional implementation, the terminal can also determine whether to feedback precoding matrices associated with N interference transmission layers according to the second network signaling sent by the network-side device.

[0058] In the embodiments 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, further interference measurement is performed based on the precoding matrix and the estimated channel; another measurement method is that the terminal assumes that each of some reference signal ports among the reference signal ports of the NZP CSI-RS is associated with a transmission layer, and for the 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 the embodiments of the present application, the network-side device can flexibly configure multiple interference measurement hypotheses for the terminal to perform interference measurement, increasing the flexibility of interference measurement.

[0059] Among them, the above different measurement methods can also be referred to as a type of interference measurement hypothesis.

[0060] In the embodiments of the present application, an interference measurement hypothesis can also be understood as a type of interference, and different interference measurement hypotheses can be understood as different types of interference. For example, the interference measurement type may be at least one of the following: measuring inter-cell interference, inter-user interference, 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.

[0061] In the embodiments 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. Among them, 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 all associated with an interference transmission layer, that is, among the multiple interference measurement signal ports of an interference measurement reference signal, there are at least some interference measurement reference signal ports for which the terminal cannot assume that the interference measurement reference signal port is associated with a transmission layer. Another understanding can be: each interference measurement reference signal port of an interference measurement reference signal is associated with a transmission layer. Therefore, the network-side device can also flexibly configure the understanding of the reference signal associated with the first interference measurement hypothesis, thereby increasing the flexibility of interference measurement.

[0062] S212, the terminal performs interference measurement based on the at least one interference measurement assumption.

[0063] In an embodiment of the present application, in an optional implementation manner, for the obtained at least one interference measurement assumption, the terminal may determine whether to measure each interference measurement assumption according to its implementation manner. In another optional implementation manner, for the obtained at least one interference measurement assumption, the terminal may determine the interference measurement assumptions to be measured according to network signaling indication. In yet another optional implementation manner, for the obtained at least one interference measurement assumption, the terminal may measure all the interference measurement assumptions. That is to say, the terminal may measure all the interference measurement assumptions among the at least one interference measurement assumption, or may measure some of them, which is not specifically limited in the embodiments of the present application.

[0064] In an optional implementation manner, before the terminal performs interference measurement based on the at least one interference measurement assumption, the method may further include at least one of the following:

[0065] 1) The terminal determines the interference measurement assumptions measured by the terminal based on network high-layer signaling;

[0066] 2) The terminal obtains the at least one interference measurement assumption based on network high-layer signaling;

[0067] 3) The terminal determines the number of interference measurement assumptions measured by the terminal based on network high-layer signaling;

[0068] 4) The terminal determines the interference measurement resources associated with each interference measurement assumption based on network high-layer signaling or protocol agreement.

[0069] For example, the network-side device may configure multiple interference measurement assumptions through high-layer signaling, and each interference measurement assumption is associated with at least one interference measurement reference signal.

[0070] Optionally, the terminal may feedback the types of interference assumptions supported by the terminal for measurement, or the terminal feedbacks the number of interference assumptions supported by the terminal for measurement.

[0071] Optionally, the protocol may stipulate the number or type of interference measurement assumptions that the network-side device can configure under the first condition, or the terminal feedbacks the number or type of interference measurement assumptions that the network-side device can configure under the first condition, where the first condition is related to at least one of the following:

[0072] 1. Interference measurement bandwidth;

[0073] 2. Number of interference measurement ports;

[0074] 3. Number of interference measurement resources;

[0075] 4. Channel measurement bandwidth;

[0076] 5. Number of channel measurement ports;

[0077] 6. Number of channel measurement resources;

[0078] 7. Measurement type, including: periodic or aperiodic or semi - persistent.

[0079] For example, the first condition may be that the number of interference measurement resources is greater than the first quantity, and the first quantity is an integer agreed upon by the protocol. Optionally, the terminal does not expect the network - side device to configure more than 2 interference measurement assumptions.

[0080] Among them, the channel measurement can be understood as the measurement of the useful signal, corresponding to the interference measurement.

[0081] In the embodiments of the present application, the terminal can measure at least one interference measurement assumption, and the first interference measurement assumption in the at least one interference measurement assumption is associated with at least one interference measurement reference signal. Thus, the network - side device can flexibly configure multiple interference measurement assumptions, facilitating more accurate acquisition of the interference situation and further improving the system transmission performance.

[0082] In the embodiments of the present application, for the at least one interference measurement reference signal associated with the first interference measurement assumption in the at least one interference measurement assumption, the terminal assumes that each interference measurement reference signal 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 rules agreed upon by the protocol or determined by the terminal according to the measurement result. 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 the N interference transmission layers through the second network signaling.

[0083] Optionally, in the embodiments of the present application, the at least one interference measurement assumption may further include a second interference measurement assumption. For the at least one interference measurement reference signal associated with the second interference measurement assumption, the terminal assumes that each interference measurement reference signal port is associated with one interference transmission layer.

[0084] Optionally, in the embodiments of the present application, one interference measurement assumption in the at least one interference measurement assumption may be associated with at least one interference measurement reference signal, and the interference measurement assumption can be used to measure the interference of neighboring cells.

[0085] Or, one interference measurement assumption in the at least one interference measurement assumption may be associated with at least one interference measurement reference signal, and the interference measurement assumption can be used to measure the interference within the serving cell.

[0086] Alternatively, for at least one interference measurement hypothesis among the at least one interference measurement hypothesis, at least one interference measurement reference signal that can be associated therewith, and the terminal assumes that the received power of each interference measurement reference signal is interference power or noise power.

[0087] In an embodiment of the present application, optionally, at least one interference measurement hypothesis measured by the terminal can be associated with the same reference signal set, or one interference measurement hypothesis can be associated with a reference signal set. Optionally, when one interference measurement hypothesis is associated with a reference signal set, the network-side device can indicate to the terminal to feedback precoding matrices associated with N interference transmission layers through a second network signaling, and the second network signaling can be configured in the signaling configuration associated with the reference signal set.

[0088] Optionally, the interference measurement reference signal can be NZP CSI-RS.

[0089] For example, the network-side device configures two interference measurement hypotheses for the terminal. The first measurement hypothesis is associated with an interference measurement reference signal set, and the terminal assumes that each reference signal port in the interference reference signal set is associated with one interference transmission layer. The second measurement hypothesis is associated with another interference measurement reference signal set, and the terminal assumes that each interference measurement reference signal in the interference reference signal set is associated with N interference transmission layers, where N is an integer indicated by the network-side device. After the terminal obtains the precoding matrices associated with the N interference transmission layers, it further performs interference measurement. Optionally, the two reference signal sets are associated with the same resource configuration signaling.

[0090] For another example, the network-side device configures an interference measurement reference signal set including two interference measurement hypotheses. The first measurement hypothesis is associated with some of the interference measurement reference signals in the interference measurement reference signal set, and the terminal assumes that each reference signal port of the some interference measurement reference signals is associated with one interference transmission layer. The second measurement hypothesis is associated with another part of the reference signals in the interference measurement reference signal set, and the terminal assumes that each interference measurement reference signal in the some interference measurement reference signals is associated with N interference transmission layers. After the terminal obtains the precoding matrices associated with the N interference transmission layers, it further performs interference measurement, where N is an integer indicated by the network-side device.

[0091] For another example, the network - side device configures 3 interference measurement hypotheses to associate a reference signal set with the terminal. The first measurement hypothesis associates the first - part reference signal resources of an interference measurement reference signal set. 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 hypothesis associates the second - part reference signal resources of the interference measurement reference signal set. The terminal assumes that each interference measurement reference signal in the interference measurement reference signals associated with this part of the reference signal resources is associated with N interference transmission layers. After the terminal obtains the precoding matrices associated with the N interference transmission layers, it further performs interference measurement, where N is an integer indicated by the network - side device. The third measurement hypothesis associates the third - part reference signal resources of the interference measurement reference signal set. The terminal assumes that the received power of the interference measurement reference signal associated with this part of the reference signal resources is the interference power or the noise power.

[0092] In an alternative implementation, as Figure 3 shown, S212 may include: S214, where the terminal determines or selects at least some of the interference measurement reference signals or at least some of the interference measurement reference signal ports for interference measurement. Optionally, the terminal may perform interference measurement based on at least some of the interference measurement reference signals or at least some of the interference measurement reference signal ports associated with the at least one interference measurement hypothesis to obtain an interference measurement result. Further optionally, it obtains CSI or a CSI report.

[0093] In an alternative implementation, the terminal's interference measurement may be based on at least one of the following Method 1 and Method 2:

[0094] 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 based on the interference measurement of the M1 interference measurement reference signals, obtains the interference measurement result, where M1 is an integer greater than 1.

[0095] Method 2: The terminal selects or determines M2 interference measurement reference signal ports from all the 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 from the interference measurement of the M2 interference measurement reference signal ports, where M2 is an integer greater than 1.

[0096] Through the above implementation, the terminal can recommend an interference combination or a scheduling combination to the network - side device, enabling the network - side device to perform more appropriate scheduling, avoiding scheduling the user and strong interference simultaneously, and improving system performance.

[0097] In the first method above, optionally, the terminal may determine the value of M1 according to the indication of the network-side device. For example, the terminal may determine the value of M1 according to the network signaling sent by the network-side device, that is, the network-side device may configure the value of M1 through network signaling. Optionally, the terminal may determine the maximum value of M1 according to 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.

[0098] For example, the network-side device configures M1 through high-layer signaling. The terminal selects M1 interference measurement reference signals from the 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 the selected ones. Optionally, the criterion for the terminal to select M1 interference measurement reference signals from the multiple interference measurement reference signals may be: select the M1 interference measurement reference signals with the largest signal-to-noise and interference ratio (SINR) or the largest CQI or the smallest interference power or the smallest reference signal received power (RSRP).

[0099] Optionally, in the case of adopting the first method above, the terminal's selection of M1 interference measurement reference signals from the multiple interference measurement reference signals associated with the first interference measurement hypothesis may include: the terminal selects M1 interference measurement reference signals from the multiple interference measurement reference signals associated with the first interference measurement hypothesis based on the third network signaling. In this optional implementation manner, the network-side device may control whether the terminal selects M1 interference measurement reference signals through high-layer signaling. In this way, it is beneficial for the network-side device to flexibly obtain the interference measurement results.

[0100] 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 interference measurement signals 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 interference measurement signals in the CSI-associated resource setting.

[0101] Optionally, in the case of adopting the first method above, the method may further include: the terminal obtains M3 configured by the network-side device, where M3 is used to indicate the minimum value of M1, and then the terminal selects at least M3 interference measurement reference signals from the multiple interference measurement reference signals associated with the first interference measurement hypothesis, where M3 is an integer greater than 0. In this optional implementation manner, the network-side device configures M3 through signaling, indicating that the terminal selects at least M3 interference measurement reference signals to obtain CSI.

[0102] 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 may indicate or the protocol may stipulate a target value. For example, a target modulation and coding scheme (MCS) 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 among the selected M1 interference measurement reference signals are. The first criterion may be: the largest SINR, the largest CQI, the smallest interference power, the smallest interference RSRP, etc.

[0103] In an alternative implementation manner, in the above-mentioned first manner, optionally, the terminal may further feedback first indication information to the network-side device, where the first indication information is used to indicate the M1 interference measurement reference signals selected by the terminal. For example, the terminal feeds back an 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.

[0104] For example, the network-side device configures an interference measurement hypothesis associated with multiple interference measurement reference signals. The terminal selects M1 interference measurement reference signals from them 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 signals among the multiple interference measurement reference signals are the M1 interference measurement reference signals selected by the terminal.

[0105] 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. Optionally, the network device configures or a protocol stipulates 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 device which M1 interference measurement reference signals are the selected ones. One implementation manner is that the terminal obtains the maximum number of interference measurement reference signals when not less than the first target value based on the first target value. Another implementation manner is that the terminal obtains the maximum number of interference measurement reference signals when 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, BLER, 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; 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.

[0106] Optionally, in the first method above, the method may further include: 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 based on a first criterion, and optionally indicates to the network device which M1 interference measurement reference signals are the selected ones. The first criterion may be: the maximum SINR or the maximum CQI or the minimum interference power or the minimum interference RSRP, etc.

[0107] In one implementation manner, in the first method above, 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 device, where 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 device to indicate the interference measurement reference signals selected by the terminal. Or, the terminal feeds back the number of interference measurement reference signals and the combination number associated with the number to the network device to indicate the interference measurement reference signals selected by the terminal. Optionally, the terminal may feed back the number of the interference measurement reference signals in the first part of the CSI report, and the network device determines the number of bits occupied by the combination number associated with the number based on the number of the interference measurement reference signals.

[0108] In one embodiment, optionally, in the above-mentioned first method, that is, when 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 the interference powers associated with the M1 interference measurement reference signals.

[0109] In one embodiment, in the above-mentioned first method, that is, when the terminal selects M1 interference measurement reference signals from multiple interference measurement reference signals to obtain CSI, the multiple interference measurement reference signals are interference measurement resources associated with the first interference measurement hypothesis determined by the terminal based on the high-layer signaling or protocol convention of the network-side device.

[0110] Similarly, in an alternative implementation, in the above-mentioned second method, 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 further include: the terminal determines the value of M2 according to the indication of the network-side device. For example, the terminal may obtain M2 configured by the network-side device. 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. 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.

[0111] In an alternative implementation, in the above-mentioned second method, 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, it may include: the terminal selects 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 the fourth network signaling. In this implementation, the network-side device controls whether the terminal selects M2 interference measurement reference signal ports through high-layer signaling. This way is beneficial for the network-side device to flexibly obtain the interference measurement result.

[0112] 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 interference measurement reference signal ports 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 interference measurement reference signal ports in the CSI-associated resource setting.

[0113] Optionally, in the above-mentioned second method, the method may further include: the terminal obtains M4 configured by the network-side device, where M4 is used to indicate the minimum value of M2, and then the terminal selects at least M4 interference measurement ports from all the 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 manner, the network-side device may configure M4 through signaling to indicate that the terminal selects 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.

[0114] Optionally, in the above-mentioned second method, the terminal may select or determine M2 interference measurement reference signal ports from all the interference measurement reference signal ports of at least one interference measurement reference signal associated with the first interference measurement hypothesis based on a second target value. In this optional implementation manner, the network-side device may indicate a second target value or the protocol may stipulate a second target value. For example, the target MCS index or the target CQI. 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.

[0115] Optionally, in the above-mentioned second method, the method may further include: the terminal selects or determines M2 interference measurement reference signal ports from all the 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 manner, 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: the maximum SINR, or the maximum CQI, or the minimum interference power, or the minimum interference RSRP, etc.

[0116] In an optional implementation manner, in the above-mentioned second method, that is, when the terminal determines or selects M2 interference measurement reference signal ports from all the ports of at least one interference measurement reference signal to obtain the interference measurement result, the method may further include: the terminal feeds back second indication information to the network-side device, where 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.

[0117] Optionally, there may be multiple pieces of second indication information. For example, the terminal feeds back multiple interference measurement reference signal port indications, and each interference measurement reference signal port indication is associated with an interference measurement reference signal, that is, the terminal indicates, through each interference measurement reference signal port indication, an interference measurement reference signal port selected from an interference measurement reference signal. Optionally, the terminal may indicate the number of interference measurement reference signal port indications to the network device through the first part of the CSI report, or the number of interference measurement reference signal port indications is equal to the number of interference measurement reference signals associated with the first interference measurement assumption.

[0118] Optionally, the second indication information may also be one. For example, the terminal feeds back an interference measurement reference signal port indication, and the interference measurement reference signal port indication is associated with at least one interference measurement reference signal. Optionally, the terminal indicates the number of interference measurement reference signal ports associated with the interference measurement reference signal port indication to the network device through the first part of the CSI report, or the number of interference measurement reference signal ports associated with the interference measurement reference signal port indication is equal to all the port numbers of the interference measurement reference signals associated with the first interference measurement assumption.

[0119] In an optional implementation manner, in the above-mentioned second method, that is, when the terminal selects M2 interference measurement reference signal ports from all the ports of at least one interference measurement reference signal to obtain interference measurement results, the method may further include: the terminal feeds back the value of M2 to the network device, or the terminal feeds back the number of interference measurement reference signal ports selected for each interference measurement reference signal to the network device.

[0120] Optionally, the terminal may feed back a combination number to the network device, and the combination number is used to determine which M2 interference measurement reference signal ports among all the interference measurement reference signal ports are the M2 interference measurement reference signal ports selected by the terminal.

[0121] Optionally, the terminal may also feed back multiple combination numbers, and each combination number is associated with an interference measurement reference signal, and the combination number is used to indicate which ports the terminal selects from the associated one interference measurement reference signal to obtain interference measurement results.

[0122] In an optional implementation manner, the interference measurement by the terminal based on at least one interference measurement assumption may further include at least one of the following:

[0123] 1) For one of 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, where the at least one interference measurement reference signal combination is an interference measurement reference signal combination configured or indicated by a 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 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 reference signal combination to obtain the interference measurement result.

[0124] 2) For one of the at least one interference measurement hypothesis, the terminal selects at least one target interference measurement reference signal port combination from 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, where the at least one interference measurement reference signal port combination is an interference measurement reference signal port combination configured or indicated by a 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 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 reference signal port combination to obtain the interference measurement result.

[0125] In the above optional implementation manner, the one interference measurement hypothesis may be the first interference measurement hypothesis, or the second interference measurement hypothesis, or other interference measurement hypotheses in the at least one interference measurement hypothesis.

[0126] In the above optional implementation manner, the network-side device configures multiple interference situations or multiple groups of interference situations for the at least one interference measurement reference signal associated with the interference measurement hypothesis. The terminal selects at least one interference situation according to network indication or protocol agreement, and further the terminal obtains the interference measurement result. In this way, the network-side device can obtain interference measurement results under different interference situations more flexibly, or the network-side device can obtain the interference situation most suitable for the terminal more accurately, further improving the transmission performance of the terminal. The multiple interference situations or multiple groups of interference situations can be understood as multiple interference combinations or multiple groups of interference combinations. For example: it can be a combination of multiple reference signal combinations or multiple reference signal port combinations or multiple reference signal set combinations or a combination of multiple reference signal groups or a combination of multiple reference signal port groups.

[0127] Optionally, the method may further include: the terminal sending third indication information or fourth indication information to the network device, where the third indication information is used to indicate at least one interference reference signal combination selected by the terminal or the fourth indication information is used to indicate at least one interference reference signal port combination selected by the terminal. Optionally, the terminal indicates at least one interference reference signal combination or at least one interference reference signal port combination selected by the terminal to the network device through a bit sequence in the first part where CSI can be reported.

[0128] Optionally, the terminal may indicate at least one interference reference signal combination to the network device, and the combination is associated with K1 interference measurement reference signals. Optionally, the terminal may further indicate an interference reference signal indication to the network device, which is used to indicate the interference measurement reference signal selected by the terminal from the interference reference signal combination. A possible implementation is that the terminal indicates a bit sequence with a length of K1 to the network device, and the interference measurement reference signals associated with the bits with a bit value of 1 in the bit sequence are the interference measurement reference signals selected by the terminal. Another possible implementation is that the terminal indicates a combination number, and the interference measurement reference signal selected by the terminal can be obtained by demapping through a protocol-agreed manner.

[0129] Optionally, the terminal may indicate at least one interference reference signal port combination to the network device, and the interference reference signal port combination is associated with K2 interference measurement reference signal ports. Optionally, the terminal may further indicate an interference reference signal port indication to the network device, which is used to indicate the interference measurement reference port combination selected by the terminal from the interference reference signal port combination.

[0130] In the above, K1 and K2 are integers greater than or equal to 0.

[0131] In the above optional implementation, for at least one interference situation selected by the terminal according to network signaling indication or protocol agreement, optionally, the network device may indicate a target value or the protocol may agree on a target value, for example, a target MCS index or a target CQI. The terminal selects at least one interference situation based on the target value. Optionally, the terminal selects at least one interference situation based on a first criterion or a second criterion, and the first criterion or the second criterion may be: the maximum SINR or the maximum CQI or the minimum interference power or the minimum interference RSRP, etc.

[0132] In an optional implementation, when the terminal performs interference measurement based on at least one interference measurement hypothesis, it may further include at least one of the following:

[0133] 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 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 according to the codebook type indicated by the fifth network signaling, determine the interference measurement equivalent channel matrix (the precoding matrix multiplied by the channel matrix) based on the precoding matrix and the channel matrix associated with the first interference measurement hypothesis, and further obtain the CSI based on the equivalent channel matrix associated with the N interference transmission layers.

[0134] 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 by the protocol, and performs interference measurement based on the precoding matrix or equivalent channel matrix. For example, the terminal can determine the N interference transmission layers according to the codebook type agreed upon by the protocol, determine the N interference transmission layers and the precoding matrix associated with the N interference transmission layers according to the codebook type, determine the interference measurement equivalent channel matrix (the precoding matrix multiplied by the channel matrix) based on the precoding matrix and the channel matrix associated with the first interference measurement hypothesis, and further obtain the CSI based on the equivalent channel matrix associated with the N interference transmission layers.

[0135] In the above optional implementation, the terminal can determine the codebook type associated with the precoding matrix of the N interference transmission layers according to the indication of the network signaling or the agreement of the protocol. In this way, the network-side device can flexibly configure the codebook type associated with the interference transmission layer, so as to obtain a more accurate interference situation.

[0136] In the above optional implementation, the terminal can also determine the frequency-domain granularity associated with the precoding matrix of the N interference transmission layers according to the indication of the network signaling or the agreement of the protocol, that is, whether the precoding matrix is broadband or sub-band.

[0137] For example, the network-side device instructs the terminal to obtain the precoding matrix of the N interference transmission layers based on the Type1 codebook or the Type2 codebook through the high-layer signaling.

[0138] For another example, the protocol stipulates that the terminal obtains the precoding matrix of the N interference transmission layers based on the Type1 codebook or the Type2 codebook.

[0139] In an optional implementation, after obtaining the above interference measurement result, the terminal can obtain a CSI report for feedback of the interference measurement result, and report the CSI report to the network-side device.

[0140] In an optional implementation, the method may further include: the terminal determines the resources occupied by obtaining a CSI report or the terminal determines the resources occupied by performing the interference measurement, where the CSI report is associated with the measurement result of the interference measurement performed by the terminal based on 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 at least one interference measurement hypothesis. The terminal has a limited resource pool. Before the terminal obtains the CSI report or obtains the interference measurement result, it may judge 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 enough, the terminal may not perform the interference measurement or update the interference measurement result.

[0141] Wherein, the resource pool may include at least one of the following:

[0142] 1), the available CSI processing unit (CPU) resource pool;

[0143] 2), the activatable reference signal resource pool;

[0144] 3), the activatable reference signal port resource pool;

[0145] 4), the activatable interference reference signal resource pool;

[0146] 5), the activatable interference reference signal port resource pool;

[0147] 6), the available CPU resource pool dedicated to interference measurement.

[0148] Optionally, the terminal may determine the resources occupied by obtaining the CSI report or determine the resources occupied by performing the interference measurement based on at least one of the following:

[0149] 1) The number of interference measurement hypotheses;

[0150] 2) The type of interference measurement hypothesis; wherein, the resources occupied by different interference measurement hypothesis types may be different.

[0151] 3) The number of interference measurement reference signals;

[0152] 4) The number of interference measurement reference signal groups;

[0153] 5) The number of interference measurement reference signals associated with the first interference measurement hypothesis;

[0154] 6) The number of interference measurement reference signal groups associated with the first interference measurement hypothesis;

[0155] 7) The number of interference measurement hypotheses associated with a predetermined codebook; wherein, the resources occupied by different codebook types may be different;

[0156] 8) The number of interference measurement reference signals associated with the interference measurement hypotheses associated with a predetermined codebook. The resources occupied by different codebook types may be different.

[0157] In the above implementation, the number or size of the resources determined by the terminal is related to at least one of the above 1) to 8). For example, the terminal determines that the CPU number occupied by interference measurement is a specific multiple of the number of interference measurement hypotheses. Another example is that the terminal determines that the CPU number occupied by interference measurement is a specific multiple of the number of reference signals associated with the interference measurement hypotheses associated with the Type 2 codebook.

[0158] Wherein, the predetermined codebook may be a codebook type separately configured by the network side device for the first interference measurement hypothesis, or the codebook type of the first interference measurement hypothesis is agreed by the protocol to be the codebook type of the signal measurement hypothesis or the channel measurement hypothesis.

[0159] Through the above method of determining resources, the network side device can make more effective use of the resources available to the terminal to obtain CSI or perform interference measurement, and try to avoid the situation that the network triggers an interference measurement or a CSI measurement, but the terminal cannot complete the measurement due to insufficient available resources.

[0160] In an alternative implementation, as Figure 4 shown, after the terminal performs interference measurement based on the at least one interference measurement hypothesis, the method may further include:

[0161] S216, the terminal obtains the CQIs associated with multiple interference measurement hypotheses based on the interference measurement results obtained from the interference measurement;

[0162] S218, the terminal feeds back the obtained CQIs to the network side device.

[0163] For example, the terminal may feed back the obtained CQIs to the network side device through a CSI report, wherein the CSI report for feeding back the CQIs and the CSI report for feeding back the interference measurement results may be the same CSI report.

[0164] In the above implementation, optionally, S216 may include at least one of the following:

[0165] 1) For each interference measurement hypothesis, the terminal respectively obtains the CQI based on the interference measurement results obtained from the interference measurement of the interference measurement hypothesis.

[0166] In this embodiment, for each interference measurement hypothesis, the terminal separately obtains the CQI and indicates it to the network. In this way, the network-side device can obtain more CQI information, so as to achieve more reasonable scheduling and improve the user transmission efficiency.

[0167] For example, the network-side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis is to measure the inter-cell interference, the second interference measurement hypothesis is to measure the inter-user interference, and the third interference measurement hypothesis is to measure both the inter-cell interference and the inter-user interference. The terminal separately obtains the CQI for each interference measurement hypothesis.

[0168] For another example, the network-side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis is to associate one transport layer with each interference measurement reference signal port, and the second interference measurement hypothesis is to associate N interference transport layers with each interference measurement reference signal. The terminal separately obtains the CQI for each interference measurement hypothesis.

[0169] 2) For each of the first interference measurement hypotheses, the terminal separately obtains the CQI based on the interference measurement result obtained by performing interference measurement on the first interference measurement hypothesis.

[0170] In this embodiment, for each first interference measurement hypothesis, the terminal separately obtains the CQI 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, so as to achieve more reasonable scheduling and improve the user transmission efficiency.

[0171] 3) The terminal determines that at least one of the interference measurement hypotheses shares the CQI based on the indication of the sixth network signaling;

[0172] In this embodiment, the terminal can determine to obtain one CQI for at least one interference measurement hypothesis based on the network signaling. In this way, the network-side device configures the terminal to obtain one CQI for multiple interference measurement hypotheses, realizing more flexible CQI acquisition and also saving the CQI indication overhead.

[0173] For example, the network-side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis is to measure the inter-cell interference, and the second interference measurement hypothesis is to measure the inter-user interference. The network can indicate through signaling that two interference measurement hypotheses are associated with one CQI, and the terminal obtains the CQI after superimposing the interferences of the two interference measurement hypotheses.

[0174] 4) The terminal determines that at least one of the first interference measurement hypotheses shares the CQI based on the indication of the seventh network signaling.

[0175] In this embodiment, the terminal may determine a CQI for at least one first interference measurement hypothesis based on network signaling. In this way, the network-side device may configure the terminal to obtain one CQI for multiple first interference measurement hypotheses, achieving more flexible CQI acquisition and saving CQI indication overhead.

[0176] 5) The terminal determines some of the interference measurement hypotheses in the at least one interference measurement hypothesis based on the indication of the eighth network signaling, and the terminal obtains the CQI based on the interference measurement results obtained by performing interference measurements on the some interference measurement hypotheses.

[0177] In this embodiment, the terminal determines, based on network signaling, to indicate the CQI to the network-side device for some interference measurement hypotheses. In this way, the network-side device may flexibly configure the terminal to obtain the CQI for some interference measurement hypotheses, saving CQI indication overhead.

[0178] 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 the CQI, or for this interference measurement hypothesis, the network-side device may indicate that the terminal does not need to feedback the CQI.

[0179] In S216, optionally, when the network-side device configures a reference CQI, for the reference interference measurement hypothesis in the at least one interference measurement hypothesis, the terminal obtains the difference value between the CQI of the reference interference measurement hypothesis and the reference CQI based on the measurement result, and uses the difference value as the CQI to be fed back for the reference interference measurement hypothesis, where the reference interference measurement hypothesis is the interference measurement hypothesis for which the network-side device configures the reference CQI. In this way, the feedback overhead of the CQI can be effectively reduced.

[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 (i.e., the reference CQI). For this interference measurement hypothesis, the terminal does not need to feedback the absolute CQI, but feedbacks the CQI offset of the absolute CQI relative to the target CQI. In this way, the feedback overhead of the CQI can be reduced.

[0181] In an alternative implementation, the method may further include: when there are multiple CQIs to be fed back, the terminal determines the priorities of the respective CQIs, where the priorities of the respective CQIs are determined by one of the following:

[0182] 1) The configuration order of the interference measurement reference signals associated with the CQI.

[0183] In this embodiment, when the terminal feeds back the CQI of multiple interference measurement hypotheses, the priorities of multiple CQIs are related to the configuration order of interference measurement reference signals. That is, each interference measurement hypothesis determines the target interference measurement reference signal that is configured earliest among at least one interference measurement reference signal associated therewith. Among multiple interference measurement hypotheses, the second interference measurement reference signal that is configured earliest among the target interference measurement reference signals associated with each has a higher priority than the second interference measurement reference signal that is configured second earliest, higher than the third earliest, and so on.

[0184] For example, the network side device configures multiple interference measurement hypotheses for the terminal. The first interference measurement hypothesis associates one transport layer with 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 transport layers with 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 that of the CQI associated with the second interference measurement hypothesis, that is, it is preferentially mapped to the uplink channel resources.

[0185] 2) The configuration order of the interference measurement hypothesis associated with the CQI.

[0186] In this embodiment, when the terminal feeds back the CQI of multiple interference measurement hypotheses, the priorities of multiple CQIs are related to the order of the interference measurement hypothesis configuration by the network side device. That is, the terminal determines the priority of the CQI according to the order of the interference measurement hypothesis configuration.

[0187] For example, the network configures 2 interference measurement hypotheses for the terminal. The terminal obtains the CQI for each interference measurement hypothesis respectively. When the terminal feeds back the CQI, the priority of the CQI associated with the first interference measurement hypothesis is higher than that of the CQI associated with the second interference measurement hypothesis, that is, it is preferentially mapped to the uplink channel resources.

[0188] Through the technical solution provided by the embodiments of the present application, the terminal can perform interference measurement based on at least one interference measurement hypothesis. Therefore, the network side device can flexibly configure multiple interference measurement hypotheses, thereby enabling the terminal to obtain a more accurate interference situation and improving the system transmission performance.

[0189] Optionally, for the association described in the embodiments of the present application, it is not limited to the following one interpretation:

[0190] A is associated with B means A is B;

[0191] A is associated with B indicates that B can be obtained through A;

[0192] A is associated with B indicates that B can be determined through A.

[0193] In the embodiments 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, and the specific embodiments of the present application are not limited.

[0194] In the embodiments of the present application, the first network signaling, the second network signaling, the third network signaling, the fourth network signaling, the fifth network signaling, the sixth network signaling, the seventh network signaling, and the eighth network signaling may be the same network signaling or different network signaling. The network signaling may be high-layer signaling, low-layer signaling, MAC layer signaling, or physical layer signaling, and the specific embodiments of the present application are not limited.
