Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining". For the purpose of brevity and ease of understanding, the terms used herein to characterize size relationships are "greater than" or "less than", "higher than" or "lower than". However, those skilled in the art can understand that the term "greater than" also covers the meaning of "greater than or equal to", and "less than" also covers the meaning of "less than or equal to"; the term "higher than" covers the meaning of "higher than or equal to", and "lower than" also covers the meaning of "lower than or equal to". The scenarios used in the embodiments of the present disclosure include but are not limited to the scenario where a network device uses multiple TRPs to provide services to a terminal, and the scenario where a network device uses multiple RRHs (Remote Radio Heads) to provide services to a terminal. The following mainly uses the scenario where a network device uses multiple TRPs to provide services to a terminal as an example. In one embodiment, the network device may use multiple TRPs to provide services to the terminal, wherein the number of TRPs may be set as required, for example, multiple TRPs include but are not limited to 4 TRPs, 3 TRPs, and 2 TRPs. The scenario in which the network device uses multiple TRPs to provide services to the terminal may also be referred to as coherent joint transmission. (Coherent Joint Transmission, CJT) scenario. In a scenario where a network device uses multiple TRPs to provide services to a terminal, the network device can configure the CSI-RS measurement configuration for each TRP for the terminal. The measurement configuration includes but is not limited to the channel measurement resource CMR and the interference measurement resource IMR. The terminal can perform measurements according to the measurement configuration and obtain the measurement results and send them to the network device. Take the example of a network device providing services to a terminal through four TRPs. The CMR configured by the network device for the terminal may include N CSI-RS resources, where N is any value of 1, 2, 3, or 4, and the CSI-RS resources correspond to the TRPs one by one. The terminal may perform measurements on the N CSI-RS resources, obtain N measurement results, and then select at least one CSI-RS resource from the N measurement results, and inform the network device of the selected at least one CSI-RS resource. That is, the terminal sends indication information of the at least one CSI-RS resource to the network device. The network device can determine the CSI-RS resource selected by the terminal based on the indication information of at least one CSI-RS resource received, and then determine the TRP corresponding to the CSI-RS resource selected by the terminal based on the correspondence between the CSI-RS resource and the TRP, and use the determined TRP to provide services to the terminal. In other words, the TRP corresponding to the CSI-RS resource selected by the terminal is the TRP that the terminal expects the network device to use. In the scenario where the network device uses multiple TRPs to provide services to the terminal, there is currently no suitable solution for the measurement of IMR. In one embodiment, the network device can configure an IMR for the terminal, and the terminal performs measurements on this IMR and reports the measurement results. However, there are certain problems with the measurement results corresponding to the IMR obtained in this way, because when the terminal selects different CSI-RS resources, the terminal can only perform measurements on one IMR. The measurement results corresponding to the IMR obtained are difficult to accurately represent the measurement results corresponding to the IMR when the terminal selects different CSI-RS resources. FIG1 is a schematic flow chart of a method for sending information according to an embodiment of the present disclosure. The method for sending information shown in this embodiment can be executed by a terminal, which includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc. The terminal can communicate with a network device, which includes but is not limited to a network device in a 4G, 5G, 6G, etc. communication system, such as a base station, a core network, etc. As shown in FIG1 , the information sending method may include the following steps: In step S101, at least one interference measurement resource IMR is determined according to first configuration information sent by a network device, wherein at least one IMR corresponds to a first channel state information reference signal CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by a terminal from multiple CSI-RS resources. In step S102, measurement is performed based on at least one CSI-RS resource and / or at least one IMR to obtain at least one measurement result. In step S103, indication information is sent to the network device, where the indication information is used to indicate at least one CSI-RS resource and / or at least one IMR corresponding to at least one measurement result. It should be noted that, after executing the above step S101, the terminal may choose to execute step S102 and / or step S103, or may choose not to execute steps S102 and S103. In one embodiment, the network device may send first configuration information to the terminal, where the first configuration information is used to configure at least one IMR for the terminal, wherein the at least one IMR corresponds to a first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. The terminal receives the first configuration information sent by the network device, and can determine at least one IMR according to the first configuration information, wherein the at least one IMR corresponds to the first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. The IMR can be used to measure interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources. In one embodiment, at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources may correspond to one IMR. In another embodiment, at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources may correspond to multiple IMRs. The correspondence between at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources and the IMR is exemplarily described in subsequent embodiments and will not be described here. In one embodiment, the measurement result may include at least one of the following: a first measurement result, a second measurement result, and a third measurement result. Several measurement results are exemplarily described below. In one embodiment, the terminal may perform measurements based on at least one IMR. For example, the terminal may perform measurement on each IMR in the at least one IMR respectively to obtain at least one first measurement result, where one first measurement result corresponds to one IMR. That is, the terminal performs measurement based on at least one IMR, and the obtained measurement result may be a measurement result corresponding to the at least one IMR. In one embodiment, the terminal may perform measurement based on at least one CSI-RS resource selected from a plurality of CSI-RS resources. For example, the terminal may perform measurement on at least one CSI-RS resource selected from the multiple CSI-RS resources to obtain a second measurement result, and the second measurement result is consistent with the at least one CSI-RS resource selected from the multiple CSI-RS resources. Corresponding to CSI-RS resources. For example, the terminal may determine at least one IMR corresponding to when at least one CSI-RS resource is selected from multiple CSI-RS resources, and then perform measurement on each IMR of the at least one IMR to obtain at least one first measurement result, where one first measurement result corresponds to one IMR. That is, the terminal performs measurement based on at least one CSI-RS resource or one IMR selected from multiple CSI-RS resources, and the obtained measurement result may be a measurement result corresponding to the at least one CSI-RS resource, or a measurement result corresponding to the IMR. In an embodiment, the terminal may perform measurement based on at least one CSI-RS resource selected from a plurality of CSI-RS resources and at least one IMR to obtain at least one measurement result. For example, the terminal may perform measurement on each IMR of at least one IMR to obtain a first measurement result corresponding to each IMR, and perform measurement on at least one CSI-RS resource selected from multiple CSI-RS resources to obtain a second measurement result corresponding to at least one CSI-RS resource, and then obtain a third measurement result based on the first measurement result and the second measurement result. In one embodiment, the above measurement results, such as the first measurement result, the second measurement result, and the third measurement result, include but are not limited to at least one of the following: CQI (Channel Quality Information), PMI (Pre-coding Matrix Indication), RI (Rank Indication), LI (Layer Indication), amplitude coefficient, phase coefficient. In one embodiment, after obtaining the measurement result, the terminal may send the measurement result to the network device, and may also send indication information to the network device. For example, the terminal performs measurement based on at least one IMR, and the indication information may indicate at least one IMR corresponding to the at least one measurement result; For example, the terminal performs measurement based on at least one CSI-RS resource selected from multiple CSI-RS resources, and the indication information may indicate at least one CSI-RS resource selected from the multiple CSI-RS resources corresponding to the at least one measurement result; For example, the terminal performs measurement based on at least one CSI-RS resource and at least one IMR selected from multiple CSI-RS resources, and the indication information may indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources corresponding to at least one measurement result and at least one CSI-RS selected by the terminal from multiple CSI-RS resources. The IMR corresponding to the resource. According to an embodiment of the present disclosure, the terminal may determine at least one IMR according to the first configuration information, wherein the at least one IMR corresponds to the first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. Accordingly, the IMR determined by the terminal may correspond to the first CSI-RS resource set, and one first CSI-RS resource set corresponds to a selection method of a CSI-RS resource. When the terminal has multiple selection methods for CSI-RS resources, multiple IMRs may be determined, and it is not limited to determining only one IMR. Among them, a CSI-RS resource selection method may correspond to one or more IMRs, that is, when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, it may correspond to one or more IMRs. The terminal can subsequently perform measurements based on at least one CSI-RS resource and / or at least one IMR to obtain at least one measurement result. Since the IMR corresponds to at least one CSI-RS resource selected by the terminal, the measured measurement result also corresponds to the at least one CSI-RS resource selected by the terminal, which is conducive to ensuring that the measurement result can accurately characterize the measurement result corresponding to at least one IMR when the terminal selects different CSI-RS resources. Then, the terminal sends indication information to the network device, indicating at least one CSI-RS resource and / or at least one IMR corresponding to at least one measurement result, so that the network device can determine at least one CSI-RS resource and / or at least one IMR corresponding to the at least one measurement result, and the measurement result can accurately characterize the measurement result corresponding to at least one IMR when the terminal selects different CSI-RS resources. FIG2 is a schematic flow chart of another information sending method according to an embodiment of the present disclosure, and the method can be executed by a terminal. As shown in FIG2, in one embodiment, the information sending method further includes: In step S201, a channel measurement resource CMR is determined according to second configuration information sent by a network device, wherein the CMR includes a plurality of CSI-RS resources. It should be noted that step S201 can be implemented independently or in combination with any other embodiment in the present disclosure. The specific method can be selected according to needs and the present disclosure is not limited thereto. In one embodiment, the network device may send second configuration information to the terminal, and the second configuration information is used to configure a CMR for the terminal. The CMR may include multiple CSI-RS resources, for example, the CMR includes N CSI-RS resources, and N can be set as needed. For example, N is less than or equal to the cell or equal to the number of TRPs that the network device provides services for the terminal. For example, if the number of TRPs that the network device provides services for the terminal is 4, then N can be any value of 1, 2, 3, or 4. The terminal receives the second configuration information sent by the network device and can determine the CMR according to the second configuration information. and multiple CSI-RS resources included in the CMR, and then at least one CSI-RS resource can be selected from the multiple CSI-RS resources included in the CMR. In one embodiment, the first configuration information and the second configuration information may be carried in the same piece of configuration information. In another embodiment, the first configuration information and the second configuration information may be carried in different pieces of configuration information. In one embodiment, the IMR may correspond to an identifier. For example, the network device configures multiple IMRs for the terminal through the first configuration information, and one IMR corresponds to one identifier. The correspondence between the identifier and the IMR may be configured by the network device for the terminal, or may be determined by the terminal based on a protocol agreement. The terminal may determine the IMR corresponding to the identifier and the identifier corresponding to the IMR based on the correspondence between the identifier and the IMR. The identifier may also be referred to as an index, or may also be referred to as a number. The identifier corresponding to the IMR is exemplarily described below through several embodiments. In one embodiment, the identifier corresponding to the IMR is a first identifier, and the first identifier is used to distinguish the IMRs included in the first set, and the IMRs included in the first set include IMRs corresponding to multiple selection methods of CSI-RS resources in multiple CSI-RS resources by the terminal. It can be understood that multiple CSI-RS resource sets can be determined based on the selection methods of these multiple CSI-RS resources, wherein each IMR in each selection method corresponds to a first identifier. In one example, the first identifier can be understood as a global identifier, which is used to uniquely identify the IMR under a selection method of a CSI-RS resource set. In one embodiment, the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from the 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. One selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMR in the first set includes multiple selections of CSI-RS resources from multiple CSI-RS resources by the terminal. For example, the IMRs in the first set include the IMRs corresponding to the three selection methods of the CSI-RS resources in the two CSI-RS resources mentioned above, that is, 5 IMRs. The network device or protocol agreement can determine a first identifier for each IMR in the IMRs corresponding to multiple selection methods. For example, the above three selection methods correspond to 5 IMRs, so a first identifier can be determined for each IMR in the 5 IMRs, and the first identifier of the IMR can be 1 to 5. For example, the first identifier of IMR#1 corresponding to selection method 1 is 1; the first identifier of IMR#2 corresponding to selection method 2 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 2; the first identifier of IMR#3 corresponding to selection method 2 for measuring interference other than CSI-RS#1 is 3; the first identifier of IMR#4 corresponding to selection method 3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 4; the first identifier of IMR#5 corresponding to selection method 3 for measuring interference other than CSI-RS#2 is 5. In one embodiment, taking the multiple CSI-RS resources as N CSI-RS resources as an example, the number of selection modes of the terminal for the CSI-RS resources in the N CSI-RS resources may be determined based on the following formula:

[0054] When the selection method is to select Ni CSI-RS resources from N CSI-RS resources, the number of corresponding IMRs can be determined based on the following formula:

[0056] in, It represents the number of selection methods when selecting Ni CSI-RS resources from N CSI-RS resources, N is an integer greater than or equal to 2, and i is an integer greater than or equal to 1 and less than or equal to N. Based on the above formula, it can be known that, for example, when N=2, the number of ways for the terminal to select CSI-RS resources in 2 CSI-RS resources is 3. The total number of IMRs corresponding to these 3 ways of selecting CSI-RS resources is 5, and an identifier is determined for each of the 5 IMRs, and the first identifier of the IMR can be 1 to 5. For example, when N=3, the number of ways for the terminal to select CSI-RS resources among the three CSI-RS resources is 7. The total number of IMRs corresponding to the seven ways of selecting CSI-RS resources is 19, and an identifier is determined for each of the 19 IMRs, and the first identifier of the IMR may be 1 to 19. For example, when N=4, the number of ways for the terminal to select CSI-RS resources among the four CSI-RS resources is 15. The total number of IMRs corresponding to these 15 ways of selecting CSI-RS resources is 65, and an identifier is determined for each of the 65 IMRs, and the first identifier of the IMR can be 1 to 65. It should be noted that the interferences corresponding to the multiple IMRs corresponding to the multiple selection modes may be the same. For example, for two IMRs with the same corresponding interference, although the interference corresponding to the two IMRs is the same, the selection methods of the CSI-RS resources corresponding to the two IMRs may be different, so the two IMRs correspond to different identifiers. For example, when N=3, there may be two IMRs among the 19 IMRs with the same interference, but because the CSI-RS resources corresponding to the two IMRs are selected in different ways, the two IMRs correspond to different identifiers. Since the first identifier is used to distinguish the IMRs included in the first set, and the IMRs included in the first set include IMRs corresponding to multiple selection methods of CSI-RS resources by the terminal among multiple CSI-RS resources, the first identifier can also be called a global identifier of the IMR. In an embodiment, the indication information is used to indicate a first identifier of an IMR corresponding to the measurement result. The terminal sends an indication message to the network device to indicate the first identifier of the IMR corresponding to the measurement result. The network device can determine the first identifier of the IMR corresponding to the received measurement result according to the indication message, and then determine the IMR corresponding to the first identifier according to the correspondence between the identifier and the IMR, that is, the IMR corresponding to the received measurement result. Taking the example of the terminal selecting at least one CSI-RS resource from two CSI-RS resources, based on the previous example, it can be known that in this case there are a total of 5 IMRs, identified from 1 to 5. For example, the terminal sends a measurement result corresponding to an IMR to the network device, and the first identifier indicated by the indication information is 3. The network device may determine, according to the first indication information, that the IMR corresponding to the received measurement result is IMR#3, and the measurement result may represent interference other than CSI-RS#1; For example, the terminal sends two measurement results corresponding to IMRs to the network device, which are measurement result #1 and measurement result #2, and the first identifiers indicated by the indication information are 4 and 5. After receiving the measurement result and the indication information, the network device may determine, based on the relationship between the measurement result and the first identifier corresponding to the IMR, that the first identifier corresponding to the measurement result #1 is 4, and the first identifier corresponding to the measurement result #2 is 5. Further, based on the first identifier 4, it may be determined that the measurement result #1 is the measurement result corresponding to IMR #4, which is used to characterize interference other than CSI-RS #1 and CSI-RS #2; and based on the first identifier 5, it may be determined that the measurement result #2 is the measurement result corresponding to IMR #5, which is used to characterize interference other than CSI-RS #2. It should be noted that the correspondence between the IMR and the first identifier may be indicated in advance to the terminal by the network device, or may be agreed upon by a protocol. In one embodiment, the indication information is carried in the first part (part I) of the CSI, or carried in the CSI The size of the first part of the CSI is fixed. The size refers to the number of bits. When the indication information indicates the first identifier, the first identifier is the identifier of the IMR in the IMR corresponding to all selection methods of the CSI-RS resource in multiple CSI-RS resources of the terminal, and the total number of IMRs corresponding to all selection methods is fixed, so the maximum value of the first identifier is fixed, so the size of the indication information used to indicate the first identifier can also be fixed, and the size of the first part of the CSI carrying the indication information can also be fixed. For example, when the terminal selects at least one CSI-RS resource from 2 CSI-RS resources, the maximum value of the first identifier is 5, and the size of the indication information can be 3 bits; for example, when the terminal selects at least one CSI-RS resource from 3 CSI-RS resources, the maximum value of the first identifier is 19, and the size of the indication information can be 5 bits; for example, when the terminal selects at least one CSI-RS resource from 4 CSI-RS resources, the maximum value of the first identifier is 65, and the size of the indication information can be 7 bits. In one embodiment, the identifier corresponding to the IMR includes a second identifier, and the second identifier is used to distinguish the IMRs included in the second set, and the IMRs included in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among the multiple CSI-RS resources. It can be understood that multiple CSI-RS resource sets can be determined based on the selection methods of these multiple CSI-RS resources, wherein one or more IMRs corresponding to each selection method in these multiple selection methods are independently numbered. In one example, the second identifier can be understood as a local identifier, which is used to uniquely identify the identifier of each IMR under a selection method of a CSI-RS resource set. The terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from these 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. One selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMRs in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among multiple CSI-RS resources, wherein the number of the second set is equal to the number of the selection methods. For example, when N=2, there are three selection methods, so there may be three second sets, second set #1, second set #2, and second set #3. The IMR in the second set #1 includes the IMR corresponding to when the terminal selects CSI-RS #1 and CSI-RS #2 from two CSI-RS resources, that is, one IMR; the IMR in the second set #2 includes the IMR corresponding to when the terminal selects CSI-RS #1 from two CSI-RS resources, that is, two IMRs; the IMR in the second set #3 includes the IMR corresponding to when the terminal selects CSI-RS #2 from two CSI-RS resources, that is, three IMRs. The network device or protocol agreement can determine a second identifier for each IMR in an IMR corresponding to a selection method, and when the selection method corresponds to only one IMR, the IMR corresponding to the selection method is fixed, and the IMR can be determined according to the selection method. Therefore, it is not necessary to determine the second identifier for the IMR corresponding to the selection method, and the indication information can only be used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. Of course, the second identifier can also be determined for the IMR corresponding to the selection method, but the selection method only corresponds to one IMR, so it only corresponds to the second identifier of one IMR. For example, if an IMR#1 corresponding to selection method 1 is selected, then the IMR corresponding to selection method 1 is fixed, and there is no need to set a second identifier for the IMR. The second identifier of IMR#2 corresponding to selection method 2 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 1; the second identifier of IMR#3 corresponding to selection method 2 for measuring interference other than CSI-RS#1 is 2. The second identifier of IMR#4 corresponding to selection method 3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 1; the second identifier of IMR#5 corresponding to selection method 3 for measuring interference other than CSI-RS#2 is 2. In one embodiment, the indication information includes first indication information and / or second indication information; wherein the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, and the second indication information is used to indicate a second identifier of the IMR corresponding to the measurement result. Since the second identifier is the identifier of the IMR in the IMR corresponding to a selection method of the CSI-RS resource among multiple CSI-RS resources, the second identifier of the IMR is different in the IMR corresponding to the same selection method, but the second identifier of the IMR can be the same in the IMR corresponding to different selection methods. For example, IMR#3 corresponding to the above selection method 2 and IMR#4 corresponding to the selection method 3, the second identifiers of the two IMRs are the same, both 1. Therefore, in order to ensure that the network device accurately distinguishes the IMR according to the second identifier, the indication information sent by the terminal to the network device may include first indication information and second indication information, and the first indication information is used to indicate that the terminal At least one CSI-RS resource selected from multiple CSI-RS resources, that is, indicating the terminal's selection method for the CSI-RS resource in the CSI-RS resources, and the second indication information is used to indicate the second identifier of the IMR corresponding to the measurement result sent to the network device. The network device can determine the terminal's selection method for CSI-RS resources in the CSI-RS resources according to the first indication information, and can determine the second identifier of the IMR corresponding to the received measurement result according to the second indication information, thereby accurately determining the IMR corresponding to the measurement result. Take the example of a terminal selecting at least one CSI-RS resource from two CSI-RS resources. For example, the terminal sends a measurement result corresponding to an IMR to the network device, the first indication information is used to indicate that the terminal selects CSI-RS#1 among 2 CSI-RS resources, and the second indication information is used to indicate that the second identifier is 1. The network device may determine, based on the first indication information and the second indication information, that the IMR corresponding to the measurement result is the IMR with the second identifier of 1 when the terminal selects CSI-RS#1 among the two CSI-RS resources, that is, IMR#2. For example, the terminal sends measurement results corresponding to two IMRs to the network device, namely measurement result #1 and measurement result #2. The first indication information is used to indicate that the terminal has selected CSI-RS #2 among the three CSI-RSs, and the second indication information is used to indicate that the second identifier is 1 and 2. After receiving the measurement result and the indication information, the network device may determine, based on the relationship between the measurement result and the second identifier corresponding to the IMR, that the second identifier corresponding to the measurement result #1 is 1, and the second identifier corresponding to the measurement result #2 is 2. Further, based on the first indication information and the second indication information, it may be determined that the measurement result #1 is an IMR with a second identifier of 1 when the terminal selects CSI-RS #2 from among the two CSI-RS resources, that is, IMR #4; and it may be determined that the measurement result #2 is an IMR with a second identifier of 2 when the terminal selects CSI-RS #2 from among the two CSI-RS resources, that is, IMR #5. It should be noted that the relationship between the IMR and the second identifier may be indicated in advance to the terminal by the network device, or may be agreed upon by a protocol. Since the second identifier is an identifier of an IMR in an IMR corresponding to a selection mode of a CSI-RS resource among multiple CSI-RS resources by the terminal, the second identifier may also be referred to as a local identifier of the IMR. In one embodiment, the indication information sent by the terminal to the network device may also include only the first indication information but not the second indication information. For example, when the selection method corresponds to only one IMR, the IMR corresponding to the selection method is fixed, and the terminal indicates the selection method through the first indication information to ensure that the network device can accurately determine the IMR corresponding to the measurement result. IMR is sent without sending the second indication information, thereby helping to save communication resources. In this case, the indication information sent by the terminal to the network device is only used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. It should be noted that when the identifier corresponding to the IMR is the first identifier, the terminal may also send indication information to the network device to indicate the CSI-RS resource selected by the terminal among multiple CSI-RS resources, so that the network device can determine the CSI-RS resource selected by the terminal among multiple CSI-RS resources. In one embodiment, the first indication information is carried in the first part (part I) of the CSI, and the second indication information is carried in the first part (part I) or the second part (part II) of the CSI; wherein the size of the first part of the CSI is fixed, and the size of the second part of the CSI is fixed or variable. In one embodiment, since the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, that is, used to indicate the terminal's selection method for CSI-RS from multiple CSI-RS resources, and when multiple CSI-RS resources have been determined, the number of multiple CSI-RS resources is fixed, and the number of selection methods for CSI-RS from multiple CSI-RS resources is fixed. Therefore, the size of the first indication information that can be used to indicate the selection method can be fixed, and the size of the first part of the CSI carrying the first indication information can also be fixed. For example, when the multiple CSI-RS resources are 2 CSI-RS resources, the size of the first indication information may be 2 bits, and the 2 bits correspond to the selection of 2 CSI-RS resources; when the multiple CSI-RS resources are 3 CSI-RS resources, the size of the first indication information may be 3 bits, and the 3 bits correspond to the selection of 3 CSI-RS resources; when the multiple CSI-RS resources are 4 CSI-RS resources, the size of the first indication information may be 4 bits, and the 4 bits correspond to the selection of 4 CSI-RS resources. In one embodiment, when the second indication information is carried in the first part of the CSI, since the size of the first part of the CSI is fixed, in order to ensure that the second indication information can indicate the second identifier of the IMR corresponding to each selection method, the number of IMRs corresponding to each selection method can be determined, and then the size of the second indication information is determined according to the maximum number of IMRs. For example, taking the example of a terminal selecting at least one CSI-RS resource from four CSI-RS resources, there are 15 selection methods. When the selection method is to select Ni CSI-RS resources from N CSI-RS resources, the number of corresponding IMRs can be based on the above formula 2 i It can be determined that the number of IMRs corresponding to each selection method is 1, 2, 4, and 8 respectively, wherein the maximum number of IMRs is 8, and the size of the second indication information can be determined based on 8, for example, the size is 3 bits. In one embodiment, when the second indication information is carried in the second part of the CSI, since the number of corresponding IMRs may be different when the terminal selects different CSI-RS resources from multiple CSI-RS resources, the size of the second indication information may vary based on the number of IMRs corresponding to the selection method, and the size of the second part of the CSI carrying the second indication information may also vary. Take, for example, that the terminal selects at least one CSI-RS resource from four CSI-RS resources. When the terminal selects 3 CSI-RS resources among 4 CSI-RS resources, for example, CSI-RS#1 is not selected, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected, corresponding to 2 IMRs, wherein the first IMR corresponds to interference outside the 4 CSI-RS resources, and the second IMR corresponds to interference outside CSI-RS#2, CSI-RS#3 and CSI-RS#4. Then the size of the second indication information can be 1 bit, which can indicate the second identifier of the 2 IMRs. When the terminal selects 2 CSI-RS resources among 4 CSI-RS resources, for example, CSI-RS#1 and CSI-RS#2 are not selected, and CSI-RS#3 and CSI-RS#4 are selected, corresponding to 4 IMRs, wherein the first IMR corresponds to interference outside the 4 CSI-RS resources, the second IMR corresponds to interference outside CSI-RS#3 and CSI-RS#4, the third IMR corresponds to interference outside CSI-RS#3, CSI-RS#4 and CSI-RS#1, and the fourth IMR corresponds to interference outside CSI-RS#3, CSI-RS#4 and CSI-RS#2. Then the size of the second indication information can be 2 bits, which can indicate the second identifiers of the 4 IMRs. When the terminal selects one CSI-RS resource among four CSI-RS resources, for example, CSI-RS#1 is selected, and CSI-RS#2, CSI-RS#3 and CSI-RS#4 are not selected, there are eight corresponding IMRs, wherein the first IMR corresponds to interference other than the four CSI-RS resources, the second IMR corresponds to interference other than CSI-RS#1, the third IMR corresponds to interference other than CSI-RS#1 and CSI-RS#2, the fourth IMR corresponds to interference other than CSI-RS#1 and CSI-RS#3, the fifth IMR corresponds to interference other than CSI-RS#1 and CSI-RS#4, the sixth IMR corresponds to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#3, the seventh IMR corresponds to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4, and the eighth IMR corresponds to interference other than CSI-RS#1, CSI-RS#3 and CSI-RS#4. Then the size of the second indication information may be 3 bits, which may indicate the second identifiers of 8 IMRs. The first identifier and the second identifier are exemplified below through several tables. Table 1 shows the identifier of the corresponding IMR when the terminal selects at least one CSI-RS resource from two CSI-RS resources. Table 1 As shown in Table 1, the terminal selects at least one CSI-RS from two CSI-RS resources, and there may be three selection methods. When the terminal selects CSI-RS#1 and CSI-RS#2, an IMR corresponds to it. The first identifier of the IMR may be 1. Since an IMR corresponds to when CSI-RS#1 and CSI-RS#2 are selected, that is, the IMR corresponding to when CSI-RS#1 and CSI-RS#2 are selected is fixed, the network device only needs to determine that the selection method is to select CSI-RS#1 and CSI-RS#2, and the IMR corresponding to the selection method can be accurately determined, so there is no need to set the second identifier. When the terminal selects CSI-RS#1, it corresponds to 2 IMRs; when CSI-RS#2 is selected, it corresponds to 2 IMRs. Among them, the first identifiers of the 2 IMRs corresponding to the selection of CSI-RS#1 can be 2 and 3, and the second identifiers of the 2 IMRs can be 1 and 2; the first identifiers of the 2 IMRs corresponding to the selection of CSI-RS#2 can be 4 and 5, and the second identifiers of the 2 IMRs corresponding to the selection of CSI-RS#2 can be 1 and 2. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 3 bits, which may be used to indicate the first identifiers 1 to 5. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information can be 2 bits, used to indicate the terminal's selection of 2 CSI-RS resources; the size of the second indication information can be 1 bit, used to indicate the second identifiers 1 and 2. Table 2 shows the identifier of the corresponding IMR when the terminal selects at least one CSI-RS resource from three CSI-RS resources (CSI-RS#1, CSI-RS#2 and CSI-RS#3). Table 2 As shown in Table 2, the terminal selects at least one CSI-RS from three CSI-RS resources. There can be 7 types: Select method. When the terminal selects CSI-RS#1, CSI-RS#2 and CSI-RS#3, one IMR corresponds to it. The first identifier of the IMR may be 1. Since one IMR corresponds to when CSI-RS#1, CSI-RS#2 and CSI-RS#3 are selected, that is, the corresponding IMR when CSI-RS#1, CSI-RS#2 and CSI-RS#3 are selected is fixed, the network device only needs to determine that the selection method is to select CSI-RS#1, CSI-RS#2 and CSI-RS#3, and the IMR corresponding to the selection method can be accurately determined, so there is no need to set the second identifier. When the terminal selects CSI-RS#2 and CSI-RS#3, two IMRs are corresponding, wherein the first identifiers of the two IMRs may be 2 and 3, and the second identifiers of the two IMRs may be 1 and 2. The case where other terminals select any two CSI-RS resources is similar and will not be described in detail here. When the terminal selects CSI-RS#1, it corresponds to 4 IMRs, wherein the first identifiers of the 4 IMRs may be 8, 9, 10, and 11, and the second identifiers of the 4 IMRs may be 1, 2, 3, and 4. The case where other terminals select any CSI-RS resource is similar and will not be described here. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 5 bits, which may be used to indicate the first identifiers 1 to 19. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information can be 3 bits, which is used to indicate the terminal's selection of 3 CSI-RS resources; when the size of the second indication information is fixed, it can be 2 bits, which is used to indicate the second identifiers 1 to 4; when the size of the second indication information is variable, it can be 1 bit or 2 bits, wherein when it is 1 bit, it is used to indicate the second identifiers 1 to 2, and when it is 2 bits, it is used to indicate the second identifiers 1 to 4. Table 3 shows the identifier of the corresponding IMR when the terminal selects at least one CSI-RS resource from four CSI-RS resources. Table 3 As shown in Table 3, the terminal selects at least one CSI-RS from 4 CSI-RS resources, and there may be 15 selection methods. When the terminal selects CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4, one IMR corresponds to it. The first identifier of the IMR may be 1. Since one IMR corresponds to when CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected, that is, the IMR corresponding to when CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected is fixed, then it is only necessary to determine that the selection method is to select CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4, and the IMR corresponding to the selection method can be accurately determined, so there is no need to set the second identifier. When the terminal selects CSI-RS#2, CSI-RS#3 and CSI-RS#4, two IMRs are corresponding. The first identifier of may be 2 and 3, and the second identifiers of the two IMRs may be 1 and 2. The case where other terminals select any three CSI-RS resources is similar, and will not be described in detail here. When the terminal selects CSI-RS#3 and CSI-RS#4, 4 IMRs are corresponding, wherein the first identifiers of the 4 IMRs may be 10, 11, 12, and 13, and the second identifiers of the 4 IMRs may be 1, 2, 3, and 4. The case where other terminals select any two CSI-RS resources is similar and will not be described in detail here. When the terminal selects CSI-RS#1, 8 IMRs are corresponding, wherein the first identifiers of the 8 IMRs may be 34, 35, 36, 37, 38, 39, 40, 41, and the second identifiers of the 8 IMRs may be 1, 2, 3, 4, 5, 6, 7, 8. The case where other terminals select any CSI-RS resource is similar and will not be described in detail here. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 7 bits, which may be used to indicate the first identifiers 1 to 65. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information can be 4 bits, used to indicate the terminal's selection of 4 CSI-RS resources; when the size of the second indication information is fixed, it can be 3 bits, used to indicate the second identifiers 1 to 8, and when the size of the second indication information is variable, it can be 1 bit, 2 bits or 3 bits, wherein when it is 1 bit, it is used to indicate the second identifiers 1 to 2, when it is 2 bits, it is used to indicate the second identifiers 1 to 4, and when it is 2 bits, it is used to indicate the second identifiers 1 to 8. It should be noted that each element in the table involved in all embodiments of the present disclosure exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in the table. Therefore, those skilled in the art can understand that the value of each element in the table is an independent embodiment. In one embodiment, the network device or the protocol agreement may determine a first identifier for each IMR in all IMRs corresponding to the selection modes, and determine a second identifier for each IMR in one IMR corresponding to the selection mode. Then, when the terminal sends the measurement result to the network device, the indication information sent to the network device may be used to indicate the first identifier, or include the second indication information used to indicate the second identifier, which may be selected as needed. In addition, in one embodiment, when the network device or protocol agrees to determine a first identifier for each IMR in the IMRs corresponding to all selection modes, the network device or protocol agrees to determine a second identifier for each IMR in the IMR corresponding to each selection mode in at least one specified selection mode. For example, for the three selection methods in Table 2 above, the network device or protocol agreement can determine the second identifier for each IMR only in the IMR corresponding to selection method 3 (the terminal selects CSI-RS#2), and In the IMR corresponding to (the terminal selects CSI-RS#1), the second identifier is not determined for each IMR. Then, when the terminal selects mode 2, the indication information sent to the network device can only be used to indicate the first identifier; when selecting mode 3, the terminal can choose to send the indication information used to indicate the first identifier to the network device, or can choose to send the indication information containing the first indication information and the second indication information to the network device, and indicate the second identifier through the second indication information. In one embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources includes at least one of the following: Interference outside of multiple CSI-RS resources; Interference caused by at least one CSI-RS resource not selected by the terminal from among the multiple CSI-RS resources. In one embodiment, when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, at least one IMR corresponds to the selected CSI-RS resource. The measurement result measured by the terminal on the IMR can represent the interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources. In an embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources may include interference outside the multiple CSI-RS resources. For example, when the terminal selects at least one CSI-RS resource from two CSI-RS resources, as shown in Table 2, when the terminal selects CSI-RS#1 and CSI-RS#2, the corresponding IMR can be used to measure interference other than CSI-RS#1 and CSI-RS#2, and the measurement result measured on the IMR can represent the interference other than CSI-RS#1 and CSI-RS#2; and when the terminal selects CSI-RS#1 or CSI-RS#2, the corresponding IMR can also include an IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the measurement result measured on the IMR can represent the interference other than CSI-RS#1 and CSI-RS#2. In an embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources may include interference of at least one CSI-RS resource not selected by the terminal from the multiple CSI-RS resources. For example, when the terminal selects at least one CSI-RS resource from two CSI-RS resources, as shown in Table 2, when the terminal selects CSI-RS#1, the corresponding IMR includes an IMR for measuring interference other than CSI-RS#1, then the measurement result measured on the IMR can represent the interference other than CSI-RS#1, for example, including the interference of the unselected CSI-RS#2; when the terminal selects CSI-RS#2, the corresponding IMR includes an IMR for measuring interference other than CSI-RS#2, then the measurement result measured on the IMR can represent the interference other than CSI-RS#2, for example, including the interference of the unselected CSI-RS#1. It can be understood that the interference of CSI-RS#1 refers to the interference from the TRP corresponding to CSI-RS#1. It should be noted that the interference involved in the above embodiments does not take into account the CSI-RS resource selected by the terminal. The interference of the source can be applied to the scenario of a single terminal performing multiple-input multiple-output (MIMO), in which the CSI-RS resource selected by the terminal is only used by the terminal. That is, the interference of the CSI-RS resource selected by the terminal is not considered. That is, the interference of the TRP corresponding to the CSI-RS resource selected by the terminal is not considered. The situation of considering the interference of the CSI-RS selected by the terminal can be applicable to the scenario of multiple terminals performing MIMO, wherein the CSI-RS resources selected by the terminal can be used not only by the terminal but also by other terminals. The situation of considering the interference of the CSI-RS selected by the terminal is exemplified by several embodiments below. In an embodiment, interference when the terminal selects at least one CSI-RS resource from a plurality of CSI-RS resources includes: interference of at least one CSI-RS resource selected by the terminal from the plurality of CSI-RS resources. Since the interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources includes the interference of the CSI-RS resource selected by the terminal, no matter which one or several CSI-RS resources are selected by the terminal from the multiple CSI-RS resources, each CSI-RS resource in the multiple CSI-RS resources may generate interference. Therefore, the interference situation that the terminal needs to consider for each selection method of CSI-RS resources among multiple CSI-RS resources is the same, so the IMR corresponding to each selection method can also be the same. Among them, a common IMR can be configured for all selection methods, and an IMR can also be configured for each selection method as needed. The number of IMRs corresponding to each selection method can be determined according to the number of multiple CSI-RS resources. For example, when the multiple CSI-RS resources are N CSI-RS resources, the number of IMRs corresponding to each selection method is equal, that is, 2. N That is, corresponding to each CSI-RS resource among the N CSI-RS resources, the IMR may include the interference corresponding to this CSI-RS resource, or may not include the interference corresponding to this CSI-RS resource. For example, when the multiple CSI-RS resources are 2 CSI-RS resources, then in the three selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 2 =4, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 4 IMRs include: IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences including CSI-RS#1 and CSI-RS#2, and IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2. If different IMRs corresponding to different selection methods use different identifiers, then the three selection methods correspond to 3×4=12 IMRs. When the IMR corresponding to the measurement result is indicated by the indication information through the first identifier, the size of the indication information can be 4 bits, which is used to indicate 1 to 12; and since the IMRs corresponding to different selection methods are the same, the IMR corresponding to the measurement result can be directly indicated by the indication information through the second identifier, and the size of the indication information can be 2 bits, which is used to indicate 1 to 4. For example, when the number of CSI-RS resources is 3 or more CSI-RS, then in the 7 selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 3 =8, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 8 IMRs include: IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#3; IMRs corresponding to interferences including CSI-RS#1, CSI-RS#2 and CSI-RS#3, and IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2 and CSI-RS#3. If different IMRs corresponding to different selection methods use different identifiers, then 7 selection methods correspond to 7×8=56 IMRs. When the IMR corresponding to the measurement result is indicated by the indication information through the first identifier, the size of the indication information can be 6 bits, which is used to indicate 1 to 56; and since the IMRs corresponding to different selection methods are the same, the IMR corresponding to the measurement result can be directly indicated by the indication information through the second identifier, and the size of the indication information can be 3 bits, which is used to indicate 1 to 8. For example, when the number of CSI-RS resources is 4 or more CSI-RS, then in the 15 selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 4 =16, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 16 IMRs include: IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#4 Corresponding IMR; IMR corresponding to interference other than CSI-RS#3 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#3; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#3 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#2, CSI-RS#3 and CSI-RS#4; IMR corresponding to interference including CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4, and IMR corresponding to interference other than CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4. If different IMRs corresponding to different selection methods use different identifiers, then 15 selection methods correspond to 15×16=240 IMRs. When the indication information indicates the IMR corresponding to the measurement result through the first identifier, the size of the indication information can be 8 bits, which is used to indicate 1 to 240. Since the IMRs corresponding to different selection methods are the same, the indication information can be directly used to indicate the IMR corresponding to the measurement result through the second identifier. The size of the information can be 4 bits, used to indicate 1 to 15. In one embodiment, the first part of the CSI further includes at least one of the following: Channel State Information Reference Signal Indication (CRI); Wideband channel quality information (CQI); an indication of the number of non-zero wideband amplitude coefficients; an indication of the number of non-zero coefficients; an indication of the locations of non-zero coefficients; Mode indication; Rank Indication (RI).

It should be noted that after executing the above step S301, the network device may choose to execute step S302 or not. In one embodiment, the network device may send first configuration information to the terminal, where the first configuration information is used to configure at least one IMR for the terminal, wherein the at least one IMR corresponds to a first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources.

In one embodiment, at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources may correspond to one IMR. In another embodiment, at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources may correspond to multiple IMRs. The correspondence between at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources and the IMR is exemplarily described in subsequent embodiments and will not be described here. In one embodiment, the measurement result may include at least one of the following: a first measurement result, a second measurement result, and a third measurement result. Several measurement results are exemplarily described below. In one embodiment, the terminal may perform measurements based on at least one IMR. For example, the terminal may perform measurement on each IMR in the at least one IMR respectively to obtain at least one first measurement result, where one first measurement result corresponds to one IMR. That is, the terminal performs measurement based on at least one IMR, and the measurement result obtained can be at least one IMR The corresponding measurement results. In one embodiment, the terminal may perform measurement based on at least one CSI-RS resource selected from a plurality of CSI-RS resources. For example, the terminal may perform measurement on at least one CSI-RS resource selected from multiple CSI-RS resources to obtain a second measurement result, where the second measurement result corresponds to the at least one CSI-RS resource selected by the terminal from the multiple CSI-RS resources. For example, the terminal may determine at least one IMR corresponding to when at least one CSI-RS resource is selected from multiple CSI-RS resources, and then perform measurement on each IMR of the at least one IMR to obtain at least one first measurement result, where one first measurement result corresponds to one IMR. That is, the terminal performs measurement based on at least one CSI-RS resource or one IMR selected from multiple CSI-RS resources, and the obtained measurement result may be a measurement result corresponding to the at least one CSI-RS resource, or a measurement result corresponding to the IMR. In an embodiment, the terminal may perform measurement based on at least one CSI-RS resource selected from a plurality of CSI-RS resources and at least one IMR to obtain at least one measurement result. For example, the terminal may perform measurement on each IMR of at least one IMR to obtain a first measurement result corresponding to each IMR, and perform measurement on at least one CSI-RS resource selected from multiple CSI-RS resources to obtain a second measurement result corresponding to at least one CSI-RS resource, and then obtain a third measurement result based on the first measurement result and the second measurement result. In one embodiment, the above measurement results, such as the first measurement result, the second measurement result, and the third measurement result, include but are not limited to at least one of the following: Channel quality information CQI, precoding matrix indication PMI, rank indication RI, layer indication LI, amplitude coefficient, phase coefficient. In one embodiment, after obtaining the measurement result, the terminal may send the measurement result to the network device, and may also send indication information to the network device. For example, the terminal performs measurement based on at least one IMR, and the indication information may indicate at least one IMR corresponding to the at least one measurement result; after receiving the indication information, the network device may determine at least one IMR corresponding to the measurement result according to the indication information. For example, the terminal performs measurement based on at least one CSI-RS resource selected from multiple CSI-RS resources. The indication information may indicate at least one CSI-RS resource selected from multiple CSI-RS resources corresponding to at least one measurement result; after receiving the indication information, the network device may determine at least one CSI-RS resource selected from multiple CSI-RS resources corresponding to the measurement result according to the indication information. For example, the terminal performs measurement based on at least one CSI-RS resource and at least one IMR selected from multiple CSI-RS resources, and the indication information may indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources corresponding to at least one measurement result and the IMR corresponding to when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources. After receiving the indication information, the network device may determine, according to the indication information, at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources corresponding to the measurement result and the IMR corresponding to when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources. According to an embodiment of the present disclosure, a network device may send first configuration information to a terminal, and the first configuration information is used to configure at least one IMR for the terminal, wherein the at least one IMR corresponds to a first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. The terminal may determine at least one IMR based on the first configuration information, wherein the at least one IMR corresponds to a first CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. Accordingly, the IMR determined by the terminal may correspond to the first CSI-RS resource set, and a first CSI-RS resource set corresponds to a selection method of a CSI-RS resource. When the terminal has multiple selection methods for CSI-RS resources, multiple IMRs may be determined, and it is not limited to determining only one IMR. Among them, a CSI-RS resource selection method may correspond to one or more IMRs, that is, when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, it may correspond to one or more IMRs. The terminal can subsequently perform measurements based on at least one CSI-RS resource and / or at least one IMR to obtain at least one measurement result. Since the IMR corresponds to at least one CSI-RS resource selected by the terminal, the measured measurement result also corresponds to the at least one CSI-RS resource selected by the terminal, which is conducive to ensuring that the measurement result can accurately characterize the measurement result corresponding to at least one IMR when the terminal selects different CSI-RS resources. Then, the network device receives the indication information sent by the terminal, and can determine at least one CSI-RS resource and / or at least one IMR corresponding to at least one measurement result according to the indication information, and the measurement result can accurately characterize the measurement result corresponding to at least one IMR when the terminal selects different CSI-RS resources. FIG4 is a schematic flow chart of another information receiving method according to an embodiment of the present disclosure, and the method can be executed by a network device. As shown in FIG4, in one embodiment, the information receiving method further includes: In step S401, second configuration information is sent to the terminal, wherein the second configuration information is used to configure the information Channel measurement resources CMR, CMR includes multiple CSI-RS resources. It should be noted that step S401 can be implemented independently or in combination with any other embodiment in the present disclosure. The specific selection can be made according to needs and the present disclosure is not limited thereto. In one embodiment, the network device may send second configuration information to the terminal, and the second configuration information is used to configure a CMR for the terminal. The CMR may include multiple CSI-RS resources, for example, the CMR includes N CSI-RS resources, and N can be set as needed. For example, N is less than or equal to the cell or equal to the number of TRPs that the network device provides services for the terminal. For example, if the number of TRPs that the network device provides services for the terminal is 4, then N can be any value of 1, 2, 3, or 4. The terminal receives the second configuration information sent by the network device and can determine the CMR and multiple CSI-RS resources included in the CMR according to the second configuration information, and then can subsequently select at least one CSI-RS resource from the multiple CSI-RS resources included in the CMR. In one embodiment, the first configuration information and the second configuration information may be carried in the same piece of configuration information. In another embodiment, the first configuration information and the second configuration information may be carried in different pieces of configuration information. In one embodiment, the IMR may correspond to an identifier. For example, the network device configures multiple IMRs for the terminal through the first configuration information, and one IMR corresponds to one identifier. The correspondence between the identifier and the IMR may be configured by the network device for the terminal, or may be determined based on a protocol agreement. The terminal may determine the IMR corresponding to the identifier and the identifier corresponding to the IMR based on the correspondence between the identifier and the IMR. The identifier may also be referred to as an index, or may also be referred to as a number. The identifier corresponding to the IMR is exemplarily described below through several embodiments. In one embodiment, the identifier corresponding to the IMR is a first identifier, and the first identifier is used to distinguish the IMRs included in the first set, and the IMRs in the first set include IMRs corresponding to multiple selection methods of CSI-RS resources in multiple CSI-RS resources by the terminal. It can be understood that multiple CSI-RS resource sets can be determined based on the selection methods of these multiple CSI-RS resources, wherein each IMR in each selection method corresponds to a first identifier. In one example, the first identifier can be understood as a global identifier, which is used to uniquely identify the IMR under a selection method of a CSI-RS resource set. In one embodiment, the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from the 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. One selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMRs in the first set include IMRs corresponding to multiple selection methods of the terminal for CSI-RS resources in multiple CSI-RS resources. For example, the IMRs in the first set include IMRs corresponding to 3 selection methods of the terminal for CSI-RS resources in the above 2 CSI-RS resources, that is, 5 IMRs. The network device or the protocol agreement may determine a first identifier for each IMR in the IMRs corresponding to the multiple selection methods. For example, if the above three selection methods correspond to five IMRs, then a first identifier may be determined for each IMR in the five IMRs. Then the first identifier of the IMR may be 1 to 5. The network device may determine the IMR corresponding to the measurement result sent by the terminal according to the first identifier. For example, the first identifier of an IMR#1 corresponding to selection mode 1 is 1; the first identifier of an IMR#2 corresponding to selection mode 2 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 2; the first identifier of an IMR#3 corresponding to selection mode 2 for measuring interference other than CSI-RS#1 is 3; the first identifier of an IMR#4 corresponding to selection mode 3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 4; the first identifier of an IMR#5 corresponding to selection mode 3 for measuring interference other than CSI-RS#2 is 5. For example, if the first identifier in the indication information received by the network device is 5, it can be determined that the measurement result sent by the terminal corresponds to IMR#5. In one embodiment, taking the multiple CSI-RS resources as N CSI-RS resources as an example, the number of selection modes of the terminal for the CSI-RS resources in the N CSI-RS resources may be determined based on the following formula:

[0216] When the selection method is to select Ni CSI-RS resources from N CSI-RS resources, the number of corresponding IMRs can be determined based on the following formula:

[0218] in, Indicates that Ni CSI-RS resources are selected from N CSI-RS resources, where N is greater than or equal to wherein n is an integer greater than or equal to 2, and i is an integer greater than or equal to 1 and less than or equal to N. Based on the above formula, it can be known that, for example, when N=2, the number of ways for the terminal to select CSI-RS resources in 2 CSI-RS resources is 3. The total number of IMRs corresponding to these 3 ways of selecting CSI-RS resources is 5, and an identifier is determined for each of the 5 IMRs, and the first identifier of the IMR can be 1 to 5. For example, when N=3, the number of ways for the terminal to select CSI-RS resources among the three CSI-RS resources is 7. The total number of IMRs corresponding to the seven ways of selecting CSI-RS resources is 19, and an identifier is determined for each of the 19 IMRs, and the first identifier of the IMR may be 1 to 19. For example, when N=4, the number of ways for the terminal to select CSI-RS resources among the four CSI-RS resources is 15. The total number of IMRs corresponding to these 15 ways of selecting CSI-RS resources is 65, and an identifier is determined for each of the 65 IMRs, and the first identifier of the IMR can be 1 to 65. It should be noted that the interference corresponding to multiple IMRs corresponding to multiple selection methods may be the same. For example, for two IMRs with the same corresponding interference, although the interference corresponding to the two IMRs is the same, the selection methods of the CSI-RS resources corresponding to the two IMRs may be different, so the two IMRs correspond to different identifiers. For example, when N=3, there may be two IMRs among the 19 IMRs whose interference corresponding to the same IMRs, but because the CSI-RS resources corresponding to the two IMRs are selected in different ways, the two IMRs correspond to different identifiers. Since the first identifier is used to distinguish the IMRs included in the first set, and the IMRs included in the first set include IMRs corresponding to multiple selection methods of the terminal for CSI-RS resources among multiple CSI-RS resources, the first identifier can also be called a global identifier of the IMR. In an embodiment, the indication information is used to indicate a first identifier of an IMR corresponding to the measurement result. The terminal sends an indication message to the network device to indicate the first identifier of the IMR corresponding to the measurement result. The network device can determine the first identifier of the IMR corresponding to the received measurement result according to the indication message, and then determine the IMR corresponding to the first identifier according to the correspondence between the identifier and the IMR, that is, the IMR corresponding to the received measurement result. Taking the example of the terminal selecting at least one CSI-RS resource from two CSI-RS resources, based on the previous example, it can be known that in this case there are a total of 5 IMRs, identified from 1 to 5. For example, the terminal sends a measurement result corresponding to an IMR to the network device, and the first identifier indicated by the indication information is 3. The network device may determine, according to the first indication information, that the IMR corresponding to the received measurement result is IMR#3. The measurement results can characterize interference other than CSI-RS#1; For example, the terminal sends two measurement results corresponding to IMRs to the network device, which are measurement result #1 and measurement result #2, and the first identifiers indicated by the indication information are 4 and 5. After receiving the measurement result and the indication information, the network device may determine, based on the relationship between the measurement result and the first identifier corresponding to the IMR, that the first identifier corresponding to the measurement result #1 is 4, and the first identifier corresponding to the measurement result #2 is 5. Further, based on the first identifier 4, it may be determined that the measurement result #1 is the measurement result corresponding to IMR #4, which is used to characterize interference other than CSI-RS #1 and CSI-RS #2; and based on the first identifier 5, it may be determined that the measurement result #2 is the measurement result corresponding to IMR #5, which is used to characterize interference other than CSI-RS #2. It should be noted that the correspondence between the IMR and the first identifier may be indicated in advance to the terminal by the network device, or may be agreed upon by a protocol. In one embodiment, the indication information is carried in the first part (part I) of the CSI, or in the second part (part II) of the CSI; wherein the size of the first part of the CSI is fixed. The size refers to the number of bits occupied. When the indication information indicates the first identifier, the first identifier is the identifier of the IMR in the IMR corresponding to all selection methods of the CSI-RS resource in multiple CSI-RS resources of the terminal, and the total number of IMRs corresponding to all selection methods is fixed, so the maximum value of the first identifier is fixed, so the size of the indication information used to indicate the first identifier can also be fixed, and the size of the first part of the CSI carrying the indication information can also be fixed. For example, when the terminal selects at least one CSI-RS resource from 2 CSI-RS resources, the maximum value of the first identifier is 5, and the size of the indication information can be 3 bits; for example, when the terminal selects at least one CSI-RS resource from 3 CSI-RS resources, the maximum value of the first identifier is 19, and the size of the indication information can be 5 bits; for example, when the terminal selects at least one CSI-RS resource from 4 CSI-RS resources, the maximum value of the first identifier is 65, and the size of the indication information can be 7 bits. In one embodiment, the identifier corresponding to the IMR includes a second identifier, and the second identifier is used to distinguish the IMRs included in the second set, and the IMRs in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among multiple CSI-RS resources. It can be understood that multiple CSI-RS resource sets can be determined based on the selection methods of these multiple CSI-RS resources, wherein one or more IMRs corresponding to each selection method in these multiple selection methods are independently numbered. In one example, the second identifier can be understood as a local identifier, which is used to uniquely identify the identifier of each IMR under a selection method of a CSI-RS resource set. The terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from these 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. A selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMRs in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among multiple CSI-RS resources, wherein the number of the second set is equal to the number of the selection methods. For example, when N=2, there are three selection methods, so there may be three second sets, second set #1, second set #2, and second set #3. The IMR in the second set #1 includes the IMR corresponding to when the terminal selects CSI-RS #1 and CSI-RS #2 from two CSI-RS resources, that is, one IMR; the IMR in the second set #2 includes the IMR corresponding to when the terminal selects CSI-RS #1 from two CSI-RS resources, that is, two IMRs; the IMR in the second set #3 includes the IMR corresponding to when the terminal selects CSI-RS #2 from two CSI-RS resources, that is, three IMRs. The network device or protocol agreement can determine a second identifier for each IMR in the IMR corresponding to a selection method, and when the selection method corresponds to only one IMR, the IMR corresponding to the selection method is fixed, and the IMR can be determined according to the selection method. Therefore, it is not necessary to determine the second identifier for the IMR corresponding to the selection method, so the indication information can only be used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. Of course, the second identifier can also be determined for the IMR corresponding to the selection method, but the selection method only corresponds to one IMR, so it only corresponds to the second identifier of one IMR. The network device can determine the IMR corresponding to the measurement result sent by the terminal based on the second identifier. For example, if an IMR#1 corresponding to selection method 1 is selected, then the IMR corresponding to selection method 1 is fixed, and there is no need to set a second identifier for the IMR. The second identifier of IMR#2 corresponding to selection method 2 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 1; the second identifier of IMR#3 corresponding to selection method 2 for measuring interference other than CSI-RS#1 is 2. The second identifier of IMR#4 corresponding to selection method 3 for measuring CSI-RS#1 and CSI-RS#2 The second identifier of IMR#4 for measuring interference other than CSI-RS#2 is 1; the second identifier of IMR#5 for measuring interference other than CSI-RS#2 corresponding to selection mode 3 is 2. For example, the network device determines that the terminal selects CSI-RS#1 among 2 CSI-RS resources according to the indication information received, and the second identifier is 1, then it can be determined that the IMR corresponding to the measurement result sent by the terminal is the IMR with the identifier of 1 when the terminal selects CSI-RS#1 among 2 CSI-RS resources, that is, IMR#2. In one embodiment, the indication information includes first indication information and / or second indication information; wherein the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, and the second indication information is used to indicate a second identifier of the IMR corresponding to the measurement result. Since the second identifier is the identifier of the IMR in the IMR corresponding to a selection method of the CSI-RS resource among multiple CSI-RS resources, the second identifier of the IMR is different in the IMR corresponding to the same selection method, but the second identifier of the IMR can be the same in the IMR corresponding to different selection methods. For example, IMR#3 corresponding to the above selection method 2 and IMR#4 corresponding to the selection method 3, the second identifiers of the two IMRs are the same, both 1. Therefore, in order to ensure that the network device accurately distinguishes the IMR according to the second identifier, the indication information sent by the terminal to the network device may include first indication information and second indication information, the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, that is, to indicate the terminal's selection method for the CSI-RS resource among the CSI-RS resources, and the second indication information is used to indicate the second identifier of the IMR corresponding to the measurement result sent to the network device. The network device can determine the terminal's selection method for CSI-RS resources in the CSI-RS resources according to the first indication information, and can determine the second identifier of the IMR corresponding to the received measurement result according to the second indication information, thereby accurately determining the IMR corresponding to the measurement result. Take the example of a terminal selecting at least one CSI-RS resource from two CSI-RS resources. For example, the terminal sends a measurement result corresponding to an IMR to the network device, the first indication information is used to indicate that the terminal selects CSI-RS#1 among 2 CSI-RS resources, and the second indication information is used to indicate that the second identifier is 1. The network device may determine, based on the first indication information and the second indication information, that the IMR corresponding to the measurement result is the IMR with the second identifier of 1 when the terminal selects CSI-RS#1 among the two CSI-RS resources, that is, IMR#2. For example, the terminal sends measurement results corresponding to two IMRs to the network device, namely measurement result #1 and measurement result #2. The first indication information is used to indicate that the terminal has selected CSI-RS #2 among the three CSI-RSs, and the second indication information is used to indicate that the second identifier is 1 and 2. After receiving the measurement results and indication information, the network device can The relationship between the first indication information and the second indication information determines that the second indication corresponding to the measurement result #1 is 1, and the second indication corresponding to the measurement result #2 is 2. Further, according to the first indication information and the second indication information, it can be determined that the measurement result #1 is an IMR with a second indication of 1 when the terminal selects CSI-RS #2 among the two CSI-RS resources, that is, IMR #4; and it can be determined that the measurement result #2 is an IMR with a second indication of 2 when the terminal selects CSI-RS #2 among the two CSI-RS resources, that is, IMR #5. It should be noted that the relationship between the IMR and the second identifier may be indicated in advance to the terminal by the network device, or may be agreed upon by a protocol. Since the second identifier is an identifier of an IMR in an IMR corresponding to a selection mode of a CSI-RS resource among multiple CSI-RS resources by the terminal, the second identifier may also be referred to as a local identifier of the IMR. In one embodiment, the indication information sent by the terminal to the network device may also include only the first indication information but not the second indication information. For example, when the selection mode corresponds to only one IMR, the IMR corresponding to the selection mode is fixed, and the terminal can ensure that the network device can accurately determine the IMR corresponding to the measurement result by indicating the selection mode through the first indication information, without sending the second indication information, thereby helping to save communication resources. In this case, the indication information sent by the terminal to the network device is only used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. It should be noted that when the identifier corresponding to the IMR is the first identifier, the terminal may also send indication information to the network device to indicate the CSI-RS resource selected by the terminal among multiple CSI-RS resources, so that the network device can determine the CSI-RS resource selected by the terminal among multiple CSI-RS resources. In one embodiment, the first indication information is carried in the first part (part I) of the CSI, and the second indication information is carried in the first part (part I) or the second part (part II) of the CSI; wherein the size of the first part of the CSI is fixed, and the size of the second part of the CSI is fixed or variable. In one embodiment, since the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, that is, used to indicate the terminal's selection method for CSI-RS from multiple CSI-RS resources, and when multiple CSI-RS resources have been determined, the number of multiple CSI-RS resources is fixed, and the number of selection methods for CSI-RS from multiple CSI-RS resources is fixed. Therefore, the size of the first indication information that can be used to indicate the selection method can be fixed, and the size of the first part of the CSI carrying the first indication information can also be fixed. For example, when the multiple CSI-RS resources are 2 CSI-RS resources, the size of the first indication information may be 2 bits, 2 bits correspond to the selection of 2 CSI-RS resources; when the multiple CSI-RS resources are 3 CSI-RS resources, the size of the first indication information may be 3 bits, 3 bits correspond to the selection of 3 CSI-RS resources; when the multiple CSI-RS resources are 4 CSI-RS resources, the size of the first indication information may be 4 bits, 4 bits correspond to the selection of 4 CSI-RS resources. In one embodiment, when the second indication information is carried in the first part of the CSI, since the size of the first part of the CSI is fixed, in order to ensure that the second indication information can indicate the second identifier of the IMR corresponding to each selection method, the number of IMRs corresponding to each selection method can be determined, and then the size of the second indication information is determined according to the maximum number of IMRs. For example, taking the example of a terminal selecting at least one CSI-RS resource from four CSI-RS resources, there are 15 selection methods. When the selection method is to select Ni CSI-RS resources from N CSI-RS resources, the number of corresponding IMRs can be based on the above formula 2 i It can be determined that the number of IMRs corresponding to each selection method is 1, 2, 4, and 8 respectively, wherein the maximum number of IMRs is 8, and the size of the second indication information can be determined based on 8, for example, the size is 3 bits. In one embodiment, when the second indication information is carried in the second part of the CSI, since the number of corresponding IMRs may be different when the terminal selects different CSI-RS resources from multiple CSI-RS resources, the size of the second indication information may vary based on the number of IMRs corresponding to the selection method, and the size of the second part of the CSI carrying the second indication information may also vary. Take, for example, that the terminal selects at least one CSI-RS resource from four CSI-RS resources. When the terminal selects 3 CSI-RS resources among 4 CSI-RS resources, for example, CSI-RS#1 is not selected, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected, corresponding to 2 IMRs, wherein the first IMR corresponds to interference outside the 4 CSI-RS resources, and the second IMR corresponds to interference outside CSI-RS#2, CSI-RS#3 and CSI-RS#4. Then the size of the second indication information can be 1 bit, which can indicate the second identifier of the 2 IMRs. When the terminal selects 2 CSI-RS resources among 4 CSI-RS resources, for example, CSI-RS#1 and CSI-RS#2 are not selected, and CSI-RS#3 and CSI-RS#4 are selected, corresponding to 4 IMRs, wherein the first IMR corresponds to interference outside the 4 CSI-RS resources, the second IMR corresponds to interference outside CSI-RS#3 and CSI-RS#4, the third IMR corresponds to interference outside CSI-RS#3, CSI-RS#4 and CSI-RS#1, and the fourth IMR corresponds to interference outside CSI-RS#3, CSI-RS#4 and CSI-RS#2. Then the size of the second indication information can be 2 bits, which can indicate the second identifiers of the 4 IMRs. When the terminal selects one CSI-RS resource among four CSI-RS resources, for example, CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are not selected, corresponding to 8 IMRs, wherein the first IMR corresponds to interference other than 4 CSI-RS resources, the second IMR corresponds to interference other than CSI-RS#1, the third IMR corresponds to interference other than CSI-RS#1 and CSI-RS#2, the fourth IMR corresponds to interference other than CSI-RS#1 and CSI-RS#3, the fifth IMR corresponds to interference other than CSI-RS#1 and CSI-RS#4, the sixth IMR corresponds to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#3, the seventh IMR corresponds to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4, and the eighth IMR corresponds to interference other than CSI-RS#1, CSI-RS#3 and CSI-RS#4. Then the size of the second indication information can be 3 bits, which can indicate the second identifiers of the 8 IMRs. The first identifier and the second identifier are exemplarily described below through several tables. Table 1 above shows the identifier of the IMR corresponding to when the terminal selects at least one CSI-RS resource from two CSI-RS resources. As shown in Table 1, the terminal selects at least one CSI-RS from two CSI-RS resources, and there may be three selection methods. When the terminal selects CSI-RS#1 and CSI-RS#2, an IMR corresponds to it. The first identifier of the IMR may be 1. Since an IMR corresponds to when CSI-RS#1 and CSI-RS#2 are selected, that is, the IMR corresponding to when CSI-RS#1 and CSI-RS#2 are selected is fixed, the network device only needs to determine that the selection method is to select CSI-RS#1 and CSI-RS#2, and the IMR corresponding to the selection method can be accurately determined, so there is no need to set the second identifier. When the terminal selects CSI-RS#1, it corresponds to 2 IMRs; when CSI-RS#2 is selected, it corresponds to 2 IMRs. Among them, the first identifiers of the 2 IMRs corresponding to the selection of CSI-RS#1 can be 2 and 3, and the second identifiers of the 2 IMRs can be 1 and 2; the first identifiers of the 2 IMRs corresponding to the selection of CSI-RS#2 can be 4 and 5, and the second identifiers of the 2 IMRs corresponding to the selection of CSI-RS#2 can be 1 and 2. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 3 bits, which may be used to indicate the first identifiers 1 to 5. The network device may determine the IMR corresponding to the received measurement result according to the first identifier. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information may be 2 bits, which is used to indicate the selection of the two CSI-RS resources by the terminal; the size of the second indication information may be 1 bit, which is used to indicate the second identifiers 1 and 2. The network device may determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. Table 2 above shows the identifier of the corresponding IMR when the terminal selects at least one CSI-RS resource from three CSI-RS resources (CSI-RS#1, CSI-RS#2 and CSI-RS#3). As shown in Table 2, the terminal selects at least one CSI-RS from three CSI-RS resources. There can be 7 types: Select method. When the terminal selects CSI-RS#1, CSI-RS#2 and CSI-RS#3, one IMR corresponds to it. The first identifier of the IMR may be 1. Since one IMR corresponds to when CSI-RS#1, CSI-RS#2 and CSI-RS#3 are selected, that is, the corresponding IMR when CSI-RS#1, CSI-RS#2 and CSI-RS#3 are selected is fixed, the network device only needs to determine that the selection method is to select CSI-RS#1, CSI-RS#2 and CSI-RS#3, and the IMR corresponding to the selection method can be accurately determined, so there is no need to set the second identifier. When the terminal selects CSI-RS#2 and CSI-RS#3, two IMRs are corresponding, wherein the first identifiers of the two IMRs may be 2 and 3, and the second identifiers of the two IMRs may be 1 and 2. The case where other terminals select any two CSI-RS resources is similar and will not be described in detail here. When the terminal selects CSI-RS#1, it corresponds to 4 IMRs, wherein the first identifiers of the 4 IMRs may be 8, 9, 10, and 11, and the second identifiers of the 4 IMRs may be 1, 2, 3, and 4. The case where other terminals select any CSI-RS resource is similar and will not be described here. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 5 bits, which may be used to indicate the first identifiers 1 to 19. The network device may determine the IMR corresponding to the received measurement result according to the first identifier. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information may be 3 bits, which is used to indicate the selection of the three CSI-RS resources by the terminal; when the size of the second indication information is fixed, it may be 2 bits, which is used to indicate the second identifiers 1 to 4; when the size of the second indication information is variable, it may be 1 bit or 2 bits, wherein when it is 1 bit, it is used to indicate the second identifiers 1 to 2, and when it is 2 bits, it is used to indicate the second identifiers 1 to 4. The network device may determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. Table 3 above shows the identifier of the corresponding IMR when the terminal selects at least one CSI-RS resource from four CSI-RS resources. As shown in Table 3, the terminal selects at least one CSI-RS from 4 CSI-RS resources, and there may be 15 selection methods. When the terminal selects CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4, one IMR corresponds to it. The first identifier of IMR can be 1. Since one IMR corresponds to it when CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected, that is, the IMR corresponding to it when CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 are selected is fixed, then it is only necessary to determine the selection method as selecting CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4 can accurately determine the IMR corresponding to the selection method, so there is no need to set the second identifier. When the terminal selects CSI-RS#2, CSI-RS#3 and CSI-RS#4, two IMRs are corresponding, wherein the first identifiers of the two IMRs may be 2 and 3, and the second identifiers of the two IMRs may be 1 and 2. The case where other terminals select any three CSI-RS resources is similar and will not be described in detail here. When the terminal selects CSI-RS#3 and CSI-RS#4, 4 IMRs are corresponding, wherein the first identifiers of the 4 IMRs may be 10, 11, 12, and 13, and the second identifiers of the 4 IMRs may be 1, 2, 3, and 4. The case where other terminals select any two CSI-RS resources is similar and will not be described in detail here. When the terminal selects CSI-RS#1, 8 IMRs are corresponding, wherein the first identifiers of the 8 IMRs may be 34, 35, 36, 37, 38, 39, 40, 41, and the second identifiers of the 8 IMRs may be 1, 2, 3, 4, 5, 6, 7, 8. The case where other terminals select any CSI-RS resource is similar and will not be described in detail here. When the indication information sent by the terminal to the network device is used to indicate the first identifier, the size of the indication information may be 7 bits, which may be used to indicate the first identifiers 1 to 65. The network device may determine the IMR corresponding to the received measurement result according to the first identifier. When the indication information sent by the terminal to the network device includes the first indication information and the second indication information, the size of the first indication information may be 4 bits, which is used to indicate the selection of the terminal for the four CSI-RS resources; when the size of the second indication information is fixed, it may be 3 bits, which is used to indicate the second identifiers 1 to 8; when the size of the second indication information is variable, it may be 1 bit, 2 bits or 3 bits, wherein when it is 1 bit, it is used to indicate the second identifiers 1 to 2, when it is 2 bits, it is used to indicate the second identifiers 1 to 4, and when it is 2 bits, it is used to indicate the second identifiers 1 to 8. The network device may determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. In one embodiment, the network device or the protocol agreement may determine a first identifier for each IMR in all IMRs corresponding to the selection modes, and determine a second identifier for each IMR in one IMR corresponding to the selection mode. Then, when the terminal sends the measurement result to the network device, the indication information sent to the network device may be used to indicate the first identifier, or include the second indication information used to indicate the second identifier, which may be selected as needed. In addition, in one embodiment, when the network device or protocol agrees to determine a first identifier for each IMR in the IMRs corresponding to all selection modes, the network device or protocol agrees to determine a second identifier for each IMR in the IMR corresponding to each selection mode in at least one specified selection mode. For example, for the three selection methods in Table 2 above, the network device or protocol agreement can determine the second identifier for each IMR only in the IMR corresponding to selection method 3 (the terminal selects CSI-RS#2), and In the IMR corresponding to (the terminal selects CSI-RS#1), the second identifier is not determined for each IMR. Then, when the terminal selects mode 2, the indication information sent to the network device can only be used to indicate the first identifier; when selecting mode 3, the terminal can choose to send the indication information used to indicate the first identifier to the network device, or can choose to send the indication information containing the first indication information and the second indication information to the network device, and indicate the second identifier through the second indication information. In one embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources includes at least one of the following: Interference outside of multiple CSI-RS resources; Interference caused by at least one CSI-RS resource not selected by the terminal from among the multiple CSI-RS resources. In one embodiment, when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources, at least one IMR corresponds to the selected CSI-RS resource. The measurement result measured by the terminal on the IMR can represent the interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources. In an embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources may include interference outside the multiple CSI-RS resources. For example, when the terminal selects at least one CSI-RS resource from two CSI-RS resources, as shown in Table 2, when the terminal selects CSI-RS#1 and CSI-RS#2, the corresponding IMR can be used to measure interference other than CSI-RS#1 and CSI-RS#2, and the measurement result measured on the IMR can represent the interference other than CSI-RS#1 and CSI-RS#2; and when the terminal selects CSI-RS#1 or CSI-RS#2, the corresponding IMR can also include an IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the measurement result measured on the IMR can represent the interference other than CSI-RS#1 and CSI-RS#2. In an embodiment, interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources may include interference of at least one CSI-RS resource not selected by the terminal from the multiple CSI-RS resources. For example, when the terminal selects at least one CSI-RS resource from two CSI-RS resources, as shown in Table 2, when the terminal selects CSI-RS#1, the corresponding IMR includes an IMR for measuring interference other than CSI-RS#1, then the measurement result measured on the IMR can represent the interference other than CSI-RS#1, for example, including the interference of the unselected CSI-RS#2; when the terminal selects CSI-RS#2, the corresponding IMR includes an IMR for measuring interference other than CSI-RS#2, then the measurement result measured on the IMR can represent the interference other than CSI-RS#2, for example, including the interference of the unselected CSI-RS#1. It can be understood that the interference of CSI-RS#1 refers to the interference from the TRP corresponding to CSI-RS#1. It should be noted that the interference involved in the above embodiments does not take into account the CSI-RS resource selected by the terminal. The interference of the source can be applied to the scenario of a single terminal performing multiple-input multiple-output (MIMO), in which the CSI-RS resource selected by the terminal is only used by the terminal. That is, the interference of the CSI-RS resource selected by the terminal is not considered. That is, the interference of the TRP corresponding to the CSI-RS resource selected by the terminal is not considered. The situation of considering the interference of the CSI-RS selected by the terminal can be applicable to the scenario of multiple terminals performing MIMO, wherein the CSI-RS resources selected by the terminal can be used not only by the terminal but also by other terminals. The situation of considering the interference of the CSI-RS selected by the terminal is exemplified by several embodiments below. In an embodiment, interference when the terminal selects at least one CSI-RS resource from a plurality of CSI-RS resources includes: interference of at least one CSI-RS resource selected by the terminal from the plurality of CSI-RS resources. Since the interference when the terminal selects at least one CSI-RS resource from multiple CSI-RS resources includes the interference of the CSI-RS resource selected by the terminal, no matter which one or several CSI-RS resources are selected by the terminal from the multiple CSI-RS resources, each CSI-RS resource in the multiple CSI-RS resources may generate interference. Therefore, the interference situation that the terminal needs to consider for each selection method of CSI-RS resources among multiple CSI-RS resources is the same, so the IMR corresponding to each selection method can also be the same. Among them, a common IMR can be configured for all selection methods, and an IMR can also be configured for each selection method as needed. The number of IMRs corresponding to each selection method can be determined according to the number of multiple CSI-RS resources. For example, when the multiple CSI-RS resources are N CSI-RS resources, the number of IMRs corresponding to each selection method is equal, that is, 2. N That is, corresponding to each CSI-RS resource among the N CSI-RS resources, the IMR may include the interference corresponding to this CSI-RS resource, or may not include the interference corresponding to this CSI-RS resource. For example, when the multiple CSI-RS resources are 2 CSI-RS resources, then in the three selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 2=4, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 4 IMRs include: IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences including CSI-RS#1 and CSI-RS#2, and IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2. If different IMRs corresponding to different selection methods use different identifiers, then 3 selection methods correspond to 3×4=12 IMRs. When the indication information indicates the IMR corresponding to the measurement result through the first identifier, the size of the indication information can be 4 bits, which are used to indicate 1 to 12. The network device can determine the IMR corresponding to the received measurement result based on the first identifier. Since the IMRs corresponding to different selection methods are the same, the indication information can be directly used to indicate the IMR corresponding to the measurement result through the second identifier. The size of the indication information can be 2 bits. Used to indicate 1 to 4, the network device can determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. For example, when the number of CSI-RS resources is 3 or more CSI-RS, then in the 7 selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 3 =8, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 8 IMRs include: IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#3; interferences including CSI-RS#1, CSI-RS#2 and CSI-RS#3, and IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2 and CSI-RS#3. If different identifiers are used for the IMRs corresponding to different selection methods, then 7 selection methods correspond to 7×8=56 IMRs. When the IMR corresponding to the measurement result is indicated by the indication information through the first identifier, the size of the indication information can be 6 bits, which are used to indicate 1 to 56. The network device can determine the IMR corresponding to the received measurement result according to the first identifier. Since the IMRs corresponding to different selection methods are the same, the IMR corresponding to the measurement result can be directly indicated by the indication information through the second identifier. The size of the indication information can be 3 bits, which are used to indicate 1 to 8. The network device can determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. For example, when the number of CSI-RS resources is 4 or more CSI-RS, then in the 15 selection methods, the number of IMRs corresponding to each selection method is equal, which is 2. 4 =16, and the interferences corresponding to the IMRs corresponding to different selection methods are also the same. Among them, the 16 IMRs include: IMRs corresponding to interferences other than CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#1; IMRs corresponding to interferences other than CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#2; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#1 and CSI-RS#4; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#3; IMRs corresponding to interferences other than CSI-RS#2 and CSI-RS#4 Corresponding IMR; IMR corresponding to interference other than CSI-RS#3 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#3; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#2 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#1, CSI-RS#3 and CSI-RS#4; IMR corresponding to interference other than CSI-RS#2, CSI-RS#3 and CSI-RS#4; IMR corresponding to interference including CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4, and IMR corresponding to interference other than CSI-RS#1, CSI-RS#2, CSI-RS#3 and CSI-RS#4. If different identifiers are used for the IMRs corresponding to different selection methods, then 15 selection methods correspond to 15×16=240 IMRs. When the IMR corresponding to the measurement result is indicated by the indication information through the first identifier, the size of the indication information can be 8 bits, which is used to indicate 1 to 240. The network device can determine the IMR corresponding to the received measurement result according to the first identifier. Since the IMRs corresponding to different selection methods are the same, the IMR corresponding to the measurement result can be directly indicated by the indication information through the second identifier. The size of the indication information can be 4 bits, which is used to indicate 1 to 15. The network device can determine the IMR corresponding to the received measurement result according to the first indication information and the second identifier. In one embodiment, the first part of the CSI also includes at least one of: a channel state information reference signal resource indication; a broadband channel quality information; an indication of the number of non-zero broadband amplitude coefficients; an indication of the number of non-zero coefficients; an indication of the position of non-zero coefficients; a mode indication; and a rank indication. In one embodiment, the mode indication may be used to indicate a CSI feedback mode, a codebook mode, etc. The CSI feedback mode may include mode 1 and mode 2. Mode 1 is feedback based on a single TRP, and mode 2 is feedback based on multiple TRPs. Of course, the CSI feedback mode may also include other modes, which are not limited in the present disclosure. The codebook mode may include codebook structure 1 and codebook structure 2. Codebook structure 1 is for all multiple CSI-RSs to feedback a frequency domain basis vector FD basis information; codebook structure 2 is for each CSI-RS in multiple CSI-RSs to feedback a frequency domain basis vector information. The codebook mode may also include other modes, which are not limited by the present disclosure. In one embodiment, the second part of the CSI also includes at least one of the following: spatial domain basis vector parameter information; frequency domain basis vector parameter information; an indication of the position of non-zero coefficients; phase coefficient information; amplitude coefficient information. FIG5 is a schematic diagram showing interaction between a terminal and a network device according to an embodiment of the present disclosure. As shown in Figure 5, the terminal can receive the first configuration information sent by the network device, and determine at least one interference measurement resource IMR based on the first configuration information, wherein at least one IMR corresponds to a first channel state information reference signal CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. The terminal can then perform measurements based on at least one CSI-RS resource and / or at least one IMR to obtain at least one measurement result. The terminal can then send indication information to the network device, wherein the indication information is used to indicate at least one CSI-RS resource and / or at least one IMR corresponding to at least one measurement result. Correspondingly, the network device may send first configuration information to the terminal, wherein the first configuration information is used to configure at least one interference measurement resource IMR, wherein the at least one IMR corresponds to a first channel state information reference signal CSI-RS resource set, and the first CSI-RS resource set includes at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources. Then the network device may receive indication information sent by the terminal, wherein the indication The indication information is used to instruct the terminal to perform measurement based on at least one CSI-RS resource and / or at least one IMR to obtain at least one CSI-RS resource and / or at least one IMR corresponding to at least one measurement result, that is, the network can determine at least one CSI-RS resource and / or at least one IMR corresponding to the measurement result according to the indication information. In one embodiment, the identifier corresponding to the IMR is a first identifier, and the first identifier is used to distinguish the IMRs included in the first set, and the IMRs included in the first set include IMRs corresponding to multiple selection methods of the terminal for CSI-RS resources among multiple CSI-RS resources. The terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from these 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. One selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMRs in the first set include IMRs corresponding to multiple selection methods of the terminal for CSI-RS resources in multiple CSI-RS resources. For example, the IMRs in the first set include IMRs corresponding to 3 selection methods of the terminal for CSI-RS resources in the above 2 CSI-RS resources, that is, 5 IMRs. The network device or protocol agreement can determine a first identifier for each IMR in the IMRs corresponding to multiple selection methods. For example, the above three selection methods correspond to 5 IMRs, so a first identifier can be determined for each IMR in the 5 IMRs, and the first identifier of the IMR can be 1 to 5. For example, the first identifier of IMR#1 corresponding to selection method 1 is 1; the first identifier of IMR#2 corresponding to selection method 2 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 2; the first identifier of IMR#3 corresponding to selection method 2 for measuring interference other than CSI-RS#1 is 3; the first identifier of IMR#4 corresponding to selection method 3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 4; the first identifier of IMR#5 corresponding to selection method 3 for measuring interference other than CSI-RS#2 is 5. In one embodiment, the identifier corresponding to the IMR includes a second identifier, and the second identifier is used to distinguish the IMRs included in the second set, and the IMRs included in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among multiple CSI-RS resources. The terminal selects at least one CSI-RS resource from multiple CSI-RS resources, and there may be multiple selection methods. Taking the multiple CSI-RS resources as 2 CSI-RS resources as an example, the 2 CSI-RS resources are CSI-RS#1 and CSI-RS#2, and the terminal selects at least one CSI-RS resource from these 2 CSI-RS resources, which may include 3 selection methods: Selection method 1: The terminal selects CSI-RS#1 and CSI-RS#2; Selection method 2: The terminal selects CSI-RS#1; Selection method 3: the terminal selects CSI-RS#2. One selection method may correspond to one or more IMRs. For example, selection method 1 corresponds to one IMR, and selection method 1 corresponds to one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2; selection method 2 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#1; selection method 3 corresponds to two IMRs, one IMR for measuring interference other than CSI-RS#1 and CSI-RS#2, and the other IMR for measuring interference other than CSI-RS#2. The IMRs in the second set include IMRs corresponding to a selection method of the terminal for CSI-RS resources among multiple CSI-RS resources, wherein the number of the second set is equal to the number of the selection methods. For example, when N=2, there are three selection methods, so there may be three second sets, second set #1, second set #2, and second set #3. The IMR in the second set #1 includes the IMR corresponding to when the terminal selects CSI-RS #1 and CSI-RS #2 from two CSI-RS resources, that is, one IMR; the IMR in the second set #2 includes the IMR corresponding to when the terminal selects CSI-RS #1 from two CSI-RS resources, that is, two IMRs; the IMR in the second set #3 includes the IMR corresponding to when the terminal selects CSI-RS #2 from two CSI-RS resources, that is, three IMRs. The network device or protocol agreement may determine a second identifier for each IMR in an IMR corresponding to a selection mode, and when the selection mode corresponds to only one IMR, the IMR corresponding to the selection mode is fixed, and the IMR can be determined according to the selection mode, so it is not necessary to determine a second identifier for the IMR corresponding to the selection mode. Of course, the second identifier may also be determined for the IMR corresponding to the selection mode, but the selection mode corresponds to only one IMR, and then only one second identifier of the IMR is corresponding. For example, if an IMR#1 corresponding to selection mode 1 is selected, then the IMR corresponding to selection mode 1 is fixed, and there is no need to set a second identifier for the IMR. The second identifier of the IMR#2 for measuring interference other than CSI-RS#1 and CSI-RS#2 corresponding to selection mode 2 is 1; The second identifier of IMR#3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 2. The second identifier of IMR#4 corresponding to selection mode 3 for measuring interference other than CSI-RS#1 and CSI-RS#2 is 1; the second identifier of IMR#5 corresponding to selection mode 3 for measuring interference other than CSI-RS#2 is 2. In one embodiment, the indication information includes first indication information and / or second indication information; wherein the first indication information is used to indicate at least one CSI-RS resource selected by the terminal from multiple CSI-RS resources, and the second indication information is used to indicate a second identifier of the IMR corresponding to the measurement result. Since the second identifier is the identifier of the IMR in the IMR corresponding to a selection method of the CSI-RS resource among multiple CSI-RS resources, the second identifier of the IMR is different in the IMR corresponding to the same selection method, but the second identifier of the IMR can be the same in the IMR corresponding to different selection methods. For example, IMR#3 corresponding to the above selection method 2 and IMR#4 corresponding to the selection method 3, the second identifiers of the two IMRs are the same, both 1.
