Description

Interference reporting method, communication apparatus, storage medium and chip system

[0001] The present application claims priority to the Chinese patent application No. 202411105688.X, filed on August 12, 2024, and entitled "Interference reporting method, communication apparatus, storage medium and chip system", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and in particular, to an interference reporting method, a communication apparatus, a storage medium and a chip system. BACKGROUND

[0003] In a wireless communication system, the transmission between a network device and a terminal can be affected by an interference signal. The interference signal can be another signal transmitted by the network device, such as a signal transmitted by the network device to another terminal; or a signal transmitted by another network device. The interference caused by the interference signal from the same network device can be referred to as intra-cell interference, and the interference caused by the interference signal from different network devices can be referred to as inter-cell interference.

[0004] Currently, joint precoding can be used to reduce intra-cell interference to improve transmission performance. In more detail, when a network device wants to transmit signals to multiple terminals, the network device performs joint precoding on the signals of the multiple terminals according to the channel state information (CSI) of the multiple terminals. Joint precoding can make the signal strength of the signal belonging to the terminal itself greater than the signal strength of the signal belonging to other terminals in the signal received by the terminal.

[0005] Although the above-mentioned method can reduce intra-cell interference, inter-cell interference still exists, which can also affect transmission performance. SUMMARY

[0006] The present application provides an interference reporting method, a communication apparatus, a storage medium and a chip system to help reduce inter-cell interference and improve transmission performance.

[0007] In a first aspect, the present application provides an interference reporting method, which can be executed by a communication apparatus. The communication apparatus can be a terminal, a communication module in the terminal, a circuit or a chip responsible for communication function in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SOC) chip or a system in package (SIP) chip containing a modem core), which is not limited in the present application. In the following, the method is taken as an example executed by a terminal.

[0008] Exemplarily, the method comprises: measuring K channel measurement resources and M interference measurement resources; and sending measurement results, the measurement results comprising measurement results corresponding to Q channel measurement resources and measurement results corresponding to N interference measurement resources, the Q channel measurement resources being Q of the K channel measurement resources, and the N interference measurement resources being N of the M interference measurement resources, wherein M, N, Q and K are positive integers, and N is less than or equal to M, and Q is less than or equal to K.

[0009] In the above technical solution, the measurement results reported by the terminal not only comprise measurement results corresponding to Q channel measurement resources, but also comprise measurement results corresponding to N interference measurement resources, which helps the network device to evade interference and improve transmission performance based on the measurement results.

[0010] In combination with the first aspect, in some possible implementation manners of the first aspect, the method further comprises: receiving first configuration information, the first configuration information being used to configure the K channel measurement resources and the M interference measurement resources.

[0011] By configuring the K channel measurement resources and the M interference measurement resources by the network device, on one hand, it is beneficial to reasonably configure the measurement resources, and thus beneficial to reduce waste of resources, so as to effectively utilize the resources and improve the efficiency of the system. On the other hand, by separately configuring the interference measurement resources, it is beneficial to better identify and evade interference signals, reduce the influence of interference on communication quality, and improve user experience.

[0012] The second aspect provides an interference reporting method, which can be executed by a communication device. The communication device can be a network device, a component (such as a circuit, a chip, a chip system, etc.) configured in the network device, or a logic module or software capable of realizing all or part of the functions of the network device, and the present application does not make any limitation in this regard. Hereinafter, the method is taken as an example executed by the network device.

[0013] Exemplarily, the method comprises: sending first configuration information, the first configuration information being used to configure K channel measurement resources and M interference measurement resources; and receiving measurement results, the measurement results comprising measurement results corresponding to Q channel measurement resources and measurement results corresponding to N interference measurement resources, the Q channel measurement resources being Q of the K channel measurement resources, and the N interference measurement resources being N of the M interference measurement resources, wherein M, N, Q and K are positive integers, and N is less than or equal to M, and Q is less than or equal to K.

[0014] In the technical solution, the measurement result reported by the terminal includes not only the measurement result corresponding to the Q channel measurement resources, but also the measurement result corresponding to the N interference measurement resources, which helps the network device to evade interference based on the measurement result, and further improves the transmission performance.

[0015] In combination with the first aspect and the second aspect, in some possible implementation manners, each of the M interference measurement resources is associated with a physical cell identifier (PCI).

[0016] Each interference measurement resource is associated with a PCI, in other words, the interference measurement resource can be used to measure the interference of the cell corresponding to the associated PCI. By associating the interference measurement with the PCI, it is helpful to identify the cell corresponding to each interference measurement resource, so as to more accurately locate the interference source, and further help to take targeted interference suppression.

[0017] A possible design is that the M interference measurement resources are associated with the same PCI, in other words, the M interference measurement resources can be used to measure the interference of the cells corresponding to the same PCI, which helps to measure the interference strengths of different interference signals of the same cell.

[0018] Another possible design is that the M interference measurement resources are associated with M different PCIs, in other words, the M interference measurement resources and the M different PCIs are one-to-one correspondence, that is, the M interference measurement resources are used to measure the interference of M different cells, so as to help measure the interference strengths of interference signals of multiple cells at a time, and help to measure more extensive interference situations.

[0019] Still another possible design is that part of the M interference measurement resources are associated with the same PCI, and another part of the interference measurement resources can be associated with different PCIs. In this way, the interference strengths of different interference signals of a certain cell can be measured, and the interference strengths of interference signals of multiple cells can be measured at a time.

[0020] In combination with the first aspect and the second aspect, in some possible implementation manners, the PCI includes the following three possible designs:

[0021] A possible design is that the PCI is included in the configuration information corresponding to each of the M interference measurement resources.

[0022] The PCI is included in the configuration information corresponding to each of the M interference measurement resources, which helps to independently configure and adjust each interference measurement resource, and is helpful to improve flexibility.

[0023] Another possible design is that the PCI is included in configuration information corresponding to a resource set / resource setting to which the M interference measurement resources belong.

[0024] By including the PCI in the configuration information of the resource set to which the M interference measurement resources belong, complexity of configuration can be reduced, and network configuration and management can be simplified.

[0025] Yet another possible design is that the PCI is included in reporting configuration corresponding to the M interference measurement resources.

[0026] In some possible implementations, in combination with the first aspect and the second aspect, the interference resource reporting mode for the measurement result includes a first reporting mode or a second reporting mode; when the interference resource reporting mode for the measurement result is the first reporting mode, the measurement result includes a measurement result of an interference measurement resource with the strongest interference to the Q channel measurement resources among the M interference measurement resources; and when the interference resource reporting mode for the measurement result is the second reporting mode, the measurement result includes a measurement result of an interference measurement resource with interference greater than or equal to a first threshold to the Q channel measurement resources among the M interference measurement resources.

[0027] When the interference resource reporting mode for the measurement result is the first reporting mode, the terminal can report the measurement result of the interference measurement resource with the strongest interference to the Q channel measurement resources among the M interference measurement resources, and reporting the measurement result of the interference measurement resource with the strongest interference helps the network device to avoid the strongest interference when scheduling / transmitting, thereby improving transmission performance. In addition, the terminal only reports the measurement result of the interference measurement resource with the strongest interference, and signaling overhead is relatively small.

[0028] When the interference resource reporting mode for the measurement result is the second reporting mode, the terminal can report the measurement result of the interference measurement resource with interference greater than or equal to a first threshold to the Q channel measurement resources among the M interference measurement resources, and reporting the measurement result of more interference measurement resources helps the network device to obtain more interference conditions, and thus better avoid interference when scheduling / transmitting, thereby improving transmission performance.

[0029] In a possible design, the network device configures the terminal with a reporting mode of interference resources for reporting the measurement result. Exemplarily, the network device sends second configuration information, which is used to configure the reporting mode of interference resources for reporting the measurement result, and the reporting mode of interference resources includes the first reporting mode or the second reporting mode. Correspondingly, the terminal receives the second configuration information.

[0030] The network device configures the reporting mode of interference resources, so that the network device can dynamically adjust according to actual needs, and the flexibility is higher.

[0031] Optionally, when the network device configures the terminal with the reporting mode of interference resources for reporting the measurement result, the following rule can be followed: if the CSI corresponding to the measurement result is wideband CSI, the second configuration information configures the first reporting mode for reporting the measurement result; if the CSI corresponding to the measurement result is sub-band CSI, the second configuration information configures the second reporting mode for reporting the measurement result.

[0032] In another possible design, the reporting mode of interference resources for reporting the measurement result is determined based on the type of CSI. The terminal determines the reporting mode of interference resources based on the type of CSI, which is beneficial to saving signaling overhead.

[0033] In a possible manner, if the CSI corresponding to the measurement result is wideband CSI, the terminal determines that the reporting mode of interference resources for reporting the measurement result is the first reporting mode; if the CSI corresponding to the measurement result is sub-band CSI, the terminal determines that the reporting mode of interference resources for reporting the measurement result is the second reporting mode.

[0034] With reference to the first aspect and the second aspect, in some possible implementations, the value of N is predefined, or the value of N is configured by the network device, or the value of N is determined by the terminal device according to a rule.

[0035] Predefining the value of N is beneficial to saving signaling overhead. Configuring the value of N by the network device is beneficial to improving the flexibility of the value of N. Determining the value of N by the terminal according to a rule is helpful to saving signaling overhead.

[0036] The value of N is determined by the terminal device according to a rule, including that the N is the number of interference measurement resources whose interference intensities on the Q channel measurement resources are greater than or equal to a first threshold. That is, the terminal can report the measurement result corresponding to the interference measurement resource whose interference intensity on the Q channel measurement resources is greater than or equal to the first threshold.

[0037] With the first aspect and the second aspect, in some possible implementation manners, the N interference measurement resources include a first interference measurement resource, the first interference measurement resource is any one of the N interference measurement resources, the interference beam reporting mode of the measurement result includes a third reporting mode or a fourth reporting mode; when the measurement result is reported in the third reporting mode, the measurement result includes information of a beam in the first interference measurement resource corresponding to a beam causing the strongest interference to the Q channel measurement resources; when the measurement result is reported in the fourth reporting mode, the measurement result includes information of a beam in the first interference measurement resource corresponding to a beam causing an interference intensity greater than or equal to a second threshold to the Q channel measurement resources.

[0038] In the third reporting mode, by reporting the information of the beam causing the strongest interference to the Q channel measurement resources, the network device can identify the main interference source, and thus take targeted interference avoidance measures. In the fourth reporting mode, by reporting the information of the beam causing the interference intensity greater than or equal to the second threshold to the Q channel measurement resources, the network device can identify more interference, and thus better avoid the interference and improve the transmission performance.

[0039] With the first aspect and the second aspect, in some possible implementation manners, the method further includes: the network device sends third configuration information, the third configuration information being used for configuring the interference beam reporting mode of the measurement result, the interference beam reporting mode including the third reporting mode or the fourth reporting mode. Correspondingly, the terminal receives the third configuration information.

[0040] The network device configures the interference beam reporting mode, so that the network device can dynamically adjust according to actual needs, and has higher flexibility.

[0041] Optionally, when the network device configures the interference beam reporting mode of the measurement result, the following rules can be followed: if the CSI corresponding to the measurement result is a wideband-level CSI, the third configuration information configures the interference beam reporting mode of the measurement result as the third reporting mode; if the CSI corresponding to the measurement result is a sub-band-level CSI, the third configuration information configures the interference beam reporting mode of the measurement result as the fourth reporting mode.

[0042] With the first aspect and the second aspect, in some possible implementation manners, the interference beam reporting mode of the measurement result is determined based on the type of the CSI, and the interference beam reporting mode includes the third reporting mode or the fourth reporting mode.

[0043] The terminal determines the interference beam reporting mode based on the type of the CSI, which is beneficial to saving signaling overhead.

[0044] In a possible manner, if the CSI corresponding to the measurement result is wideband level CSI, the terminal determines that the interference beam reporting mode used by the measurement result is the third reporting mode; if the CSI corresponding to the measurement result is subband level CSI, the terminal determines that the interference beam reporting mode used by the measurement result is the fourth reporting mode.

[0045] In some possible implementation manners, in combination with the first aspect and the second aspect, the measurement result includes one or more of the following: the value of N, a first bit bitmap, information of the N interference measurement resources, a second bit bitmap corresponding to each of the N interference measurement resources, the number of beams corresponding to each of the N interference measurement resources, or information of the beams corresponding to each of the N interference measurement resources.

[0046] Each bit in the first bit bitmap corresponds to an interference measurement resource, and each bit is used to indicate whether the measurement result includes the measurement result of the corresponding interference measurement resource.

[0047] Each bit in the second bit bitmap corresponds to a beam of the interference measurement resource corresponding to the second bit bitmap, and is used to indicate whether the measurement result includes information of the beam.

[0048] Optionally, the information of the N interference measurement resources includes one or more of the following: indexes of the N interference measurement resources, interference intensities corresponding to the N interference measurement resources, or CSI of the Q channel measurement resources under the interference of the N interference measurement resources.

[0049] The information of the beams corresponding to each of the N interference measurement resources includes one or more of the following: indexes of the beams, intensities of the beams, or CSI of the Q channel measurement resources under the interference of each of the N interference measurement resources.

[0050] In some possible implementation manners, in combination with the first aspect and the second aspect, the measurement result includes a first part (part 1) and a second part (part 2), wherein the first part is used to indicate one or more of the following: the value of N, a first bit bitmap, and the number of beams corresponding to each of the N interference measurement resources; and the second part is used to indicate one or more of the following: information of the N interference measurement resources, a second bit bitmap corresponding to each of the N interference measurement resources, or information of the beams corresponding to each of the N interference measurement resources.

[0051] In the above scheme, the two-part reporting of the measurement results is adopted, the first part can contain relatively rough information, and the second part contains more detailed information, which helps the network device to determine whether more detailed measurement results are needed according to the relatively rough measurement results of the first part. This step-by-step refinement method can improve the feedback efficiency, so that the system can respond more quickly to channel changes. In addition, it is helpful to flexibly select whether to report detailed measurement results or rough measurement results according to the actual demand and channel change situation, thereby optimizing the use of feedback resources.

Each module can realize the corresponding function by executing a computer program. The above modules can be implemented by software, or by hardware, or by a combination of software and hardware.

[0056] Optionally, the apparatus can further include a communication interface configured to enable the apparatus to communicate with other communication apparatuses.

[0057] A possible design is that the communication apparatus provided in the fourth aspect can be a terminal, a communication module in the terminal, or a chip (such as a modem chip (also known as a baseband chip) or an SOC or SIP chip containing a modem module) responsible for communication functions in the terminal.

[0058] Another possible design is that the communication apparatus provided by the fourth aspect can be a network device, or a component configured in the network device, such as a chip, a chip system, or a processor, etc.

[0081] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0082] The technical solutions provided by the present application can be applied to various communication systems, such as a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a sidelink communication system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) mobile communication system or a new radio access technology (NR). The 5G mobile communication system can include non-standalone (NSA) and / or standalone (SA).

[0083] The technical solutions provided by the present application can also be applied to future communication systems. The present application does not limit this.

[0084] To facilitate understanding of the method provided by the present application, the following points will be explained first.

[0085] First, in order to facilitate clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", etc. are used to distinguish the same or similar items or functions with basically the same function and role. For example, the first configuration information and the second configuration information are only used to distinguish different configuration information, and do not limit the order. Those skilled in the art can understand that the terms "first", "second", etc. do not limit the quantity and execution order, and the terms "first", "second", etc. also do not necessarily mean different.

[0086] Second, in the embodiments shown in the present application, each term and English abbreviation, such as channel state information (CSI), synchronization signal block (SSB), or transmission configuration indicator (TCI), is an example given for convenience of description, and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other terms capable of achieving the same or similar functions in existing or future protocols.

[0087] Third, the "protocol" involved in the embodiments of the present application can refer to a standard protocol in the communication field, which can include LTE protocol, NR protocol and related protocols applied in future communication systems, and the present application does not limit this.

[0088] Fourth, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the following cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b and c can represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b and c can be single or multiple.

[0089] Fifthly, in the present application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by certain information is referred to as to-be-indicated information, and there are many ways to indicate the to-be-indicated information in the specific implementation process, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship; only a part of the to-be-indicated information can be indicated, and other parts of the to-be-indicated information are known or agreed in advance, for example, the indication of a specific information can be realized by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The specific manner of indication is not limited in the present application. It can be understood that the indication information can be used to indicate the to-be-indicated information for the sender of the indication information, and the indication information can be used to determine the to-be-indicated information for the receiver of the indication information.

[0090] Sixthly, in the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to a terminal" can be understood as that the destination of the information is the terminal, which can include direct sending through the air interface, and also includes indirect sending through the air interface by other units or modules. "Receiving configuration information from a network device" can be understood as that the source of the configuration information is the network device, which can include receiving directly from the network device through the air interface, and also can include receiving indirectly from the network device through the air interface from other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0091] In other words, sending and receiving can be carried out between devices, for example, between a network device and a terminal; or can be carried out within a device, for example, between components, between modules, between chips, between software modules or hardware modules in the device through a bus, a wire or an interface.

[0092] It can be understood that the information can be processed as necessary before being sent by the source to the destination, such as encoding and modulation, and the destination can also perform corresponding processing after receiving the information from the source, such as decoding and demodulation, so as to interpret the valid information from the source. Similar expressions in the present application can be understood similarly, and will not be repeated here.

[0093] Seventhly, in the present application, the descriptions such as "when", "in the case of", "if", and "whether" all refer to the objective situation that the device (such as a network device or a terminal) will make corresponding processing, not the time limit, and also does not require the device (such as a network device or a terminal) to have a judgment action when it is implemented, nor does it mean that there are other limitations.

[0094] Eighthly, the corresponding relationship shown in each table in the present application can be configured or predefined. The values of the information in each table are only examples, and other values can be configured, which are not limited in the present application. When configuring the corresponding relationship of the information and each parameter, it is not necessarily required to configure all the corresponding relationships shown in each table. For example, the corresponding relationship shown in some rows in the table in the present application can also not be configured. For another example, the above tables can be appropriately deformed and adjusted, such as splitting, merging, and the like. The names of the parameters shown in the titles of the above tables can also use other names that can be understood by the communication device, and the values or representations of the parameters can also use other values or representations that can be understood by the communication device. The above tables can also use other data structures when implemented, such as arrays, queues, containers, stacks, linear tables, pointers, linked lists, trees, graphs, structures, classes, heaps, hash tables, and the like.

[0095] Ninthly, in the present application, the predefinition can also be understood as definition, predefinition, storage, pre-storage, pre-negotiation, pre-configuration, solidification, or pre-burning.

[0096] The communication system and the scenario to which the method provided by the present application is applicable will be described in detail below with reference to the accompanying drawings.

[0097] FIG. 1 is a schematic diagram of the architecture of a communication system applicable to the method provided by the present application. FIG. 1 shows a schematic diagram of a possible, non-limiting system architecture.

[0098] As shown in FIG. 1, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc., can also be included in the RAN 100. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0099] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4th generation (4G) mobile communication system, a 5G mobile communication system, or a future-oriented evolved system (e.g., a future communication system). The RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (Wi-Fi) system. The RAN 100 can also be a communication system in which two or more of the above systems are fused.

[0100] The RAN node 110, which can also be referred to as a network device, an access network device, a RAN entity, or an access node, etc., is a part of the communication system and helps the terminal to realize wireless access. The multiple RAN nodes 110 in the communication system 1000 can be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, the network element 120i in FIG. 1 can be a helicopter or a drone, which can be configured as a mobile base station. For those terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication apparatuses, for example, the network elements 110a and 110b in FIG. 1 can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0101] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future communication system, or an access node in a Wi-Fi system, etc. The RAN node can be a macro base station (e.g., 110a in FIG. 1), a micro base station or an indoor station (e.g., 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0102] In another possible scenario, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes implement part of the functions of a base station respectively. For example, the RAN node can be a control unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0103] In this application, the access network device can generally be provided with a communication module, circuit or chip for performing corresponding communication functions. The access network device can also be configured with program instructions for performing corresponding communication functions and corresponding program instructions.

[0104] A terminal can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal device, a wireless communication device, a user agent, or a user apparatus. A communication module, a circuit, or a chip for performing a corresponding communication function is usually provided in a terminal. A program instruction configured to perform a corresponding communication function is also provided in the terminal.

[0105] A terminal can be a device that provides voice / data connectivity to a user, such as a handheld device with wireless connectivity, a vehicle-mounted device, etc. Currently, some examples of terminals can be a mobile phone, a tablet, a computer (such as a notebook, a palm computer, etc.) with wireless transceiver function, a mobile internet device (MID), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a drone, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a transport vehicle with wireless communication function, a communication module, a terminal in a 5G network, or a terminal in a future evolved public land mobile network (PLMN), etc.

[0106] In addition, the terminal can also be a terminal in an internet of things (IoT) system. The IoT is an important part of future information technology development, and its main technical feature is to connect objects through communication technology and network to realize the intelligent network of man-machine interconnection and object-object interconnection. IoT technology can achieve mass connection, deep coverage and terminal power saving through, for example, narrow band (NB) technology.

[0107] In addition, the terminal can also include a smart printer, a train detector, a gas station sensor, and the like, and the main functions include collecting data (part of the terminal), receiving control information and downlink data of a network device, and transmitting electromagnetic waves to transmit uplink data to the network device.

[0108] In the embodiments of the present application, the network device can be, for example, the RAN node 110 shown in FIG. 1, and the terminal can be, for example, the terminal 120 shown in FIG. 1. The type of the network device and the terminal is not limited in the present application.

[0109] In addition, the terminal and the network device can be a hardware device, or a software function running on a special hardware, a software function running on a general hardware, such as a virtualized function instantiated on a platform (for example, a cloud platform), or an entity including a special or general hardware device and a software function. The specific form of the terminal and the network device is not limited in the present application.

[0110] FIG. 2 is another architecture diagram of a communication system suitable for the method provided in the present application. The communication system shown in FIG. 2 can be regarded as a simplification of the communication system shown in FIG. 1.

[0111] As shown in a) of FIG. 2, the communication system includes one or more network devices (one network device is taken as an example in the figure) and one or more terminals (two terminals are taken as an example in the figure), and it can be seen that one network device can transmit data or control signaling to one or more terminals.

[0112] As shown in b) of FIG. 2, the communication system includes one or more network devices (three network devices are taken as an example in the figure) and one or more terminals (one terminal is taken as an example in the figure), and it can be seen that multiple network devices can transmit data or control signaling to one terminal.

[0113] In the communication systems shown in a) of FIG. 2 and b) of FIG. 2, the terminal can be mobile or fixed. The network device can be a micro base station, a TRP or other types of network devices, and the embodiments of the present application do not limit this. The network device can provide communication coverage for a specific geographic area, and can communicate with a terminal located in the coverage area (cell) through a wireless link.

[0114] Optionally, the communication system shown in the figure can include more network devices, and each network device can include other numbers of terminals within its coverage, which are not limited in the embodiments of the present application.

[0115] It can be understood that the system architecture described in FIG. 1 and FIG. 2 is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0116] FIG. 3 is a schematic diagram of a scenario suitable for the method provided by the present application.

[0117] As shown in FIG. 3, multiple network devices can send signals to multiple terminals, such as that network device 1 sends signals to terminal 1, and network device 2 sends signals to terminal 2. The transmission between the network device and the terminal can be affected by an interference signal. The interference signal can be other signals sent by the network device, such as signals sent by the network device to other terminals; or signals sent by other network devices. The interference caused by the interference signal from the same network device can be referred to as intra-cell interference, and the interference caused by the interference signal from different network devices can be referred to as inter-cell interference.

[0118] An example, as shown in FIG. 3, for a certain terminal, such as terminal 1, terminal 1 can be interfered by signals from network device 2 when receiving signals from network device 1, which can be referred to as inter-cell interference. Wherein, network device 1 and network device 2 can be the same cell or different cells, which are not limited in the present application.

[0119] Another example, as shown in FIG. 3, for a certain terminal, such as terminal 1, terminal 1 can be interfered by signals sent by network device 1 to terminal 2 when receiving signals from network device 1, which can be referred to as intra-cell interference.

[0120] At present, joint precoding can be used to reduce intra-cell interference. In more detail, when a network device wants to send signals to multiple terminals, the network device performs joint precoding on the signals of the multiple terminals according to the CSI of the multiple terminals. Joint precoding can make the signal strength of the signal belonging to the terminal itself greater than the signal strength of the signal belonging to other terminals in the signal received by the terminal.

[0121] Although joint precoding can reduce intra-cell interference, inter-cell interference still exists, which can still affect the transmission performance.

[0122] Similarly, inter-cell interference can also be precoded jointly. In more detail, when multiple network devices are to send signals to multiple terminals, the multiple network devices jointly perform joint precoding processing, so as to reduce the interference between different cells, and make the signal strength of the signal belonging to the terminal itself greater than the signal strength of the signal belonging to other terminals (i.e. the signal from other network devices).

[0123] The multiple network devices jointly perform joint precoding processing, which requires that the network devices can cooperate ideally, and therefore, mutual calibration needs to be performed between the network devices. However, it is relatively difficult to perform accurate calibration between the network devices, and in actual scenarios, most network devices cannot meet the requirement of ideal cooperation, and it is relatively difficult to reduce inter-cell interference by joint precoding.

[0124] Therefore, in some scenarios, such as when the network devices cannot meet the ideal cooperation, inter-cell interference can still exist, and thus affect the transmission performance.

[0125] Therefore, the present application provides an interference reporting method. A terminal can measure K channel measurement resources and M interference measurement resources, obtain measurement results corresponding to the interference measurement resources and channel state information of the channel measurement resources under the interference of the interference measurement resources, and report the measurement results to a network device. Accordingly, the network device can obtain the interference of the terminal. In this way, the network device can schedule or transmit based on the interference, thereby reducing the interference of other network devices on the terminal and improving the transmission performance. In addition, the scheme provided by the present application does not require ideal cooperation between network devices, and is applicable to more scenarios and has higher universality.

[0126] The interference reporting method provided by the present application will be described in detail below with reference to the accompanying drawings. In the following, the method is described by taking the interaction between a network device and a terminal as an example, but this should not constitute any limitation on the present application. The network device can also be replaced by a component (such as a circuit, a chip, a chip system, a processor, etc.) configured in the network device, or a logic module or software capable of realizing all or part of the functions of the network device. The terminal can be replaced by a communication module or a chip (such as a modem chip (also known as a baseband chip) or an SOC or SIP chip containing a modem module) configured in the terminal and responsible for the communication function.

[0127] FIG. 4 is a schematic flowchart of an interference reporting method 400 provided by an embodiment of the present application. The steps in the method 400 will be described in detail below.

[0128] In step 410, a terminal measures K channel measurement resources and M interference measurement resources.

[0129] K, M are positive integers, for example, M = 1, K = 1. The channel measurement resource can be understood as a resource for channel measurement, and the interference measurement resource can be understood as a resource for interference measurement. In this application, measuring the channel measurement resource can be understood as measuring the signal on the channel measurement resource, and similarly, measuring the interference measurement resource can be understood as measuring the signal (also referred to as interference signal) on the interference measurement resource.

[0130] Optionally, the type of the above-mentioned channel measurement resource can be a non-zero power channel state information-reference signal (CSI-RS) resource or a synchronization signal block (SSB) resource.

[0131] Optionally, the type of the above-mentioned interference measurement resource can be a non-zero power CSI-RS resource, a zero power CSI-RS resource, a channel state information-interference measurement (CSI-IM) resource or an SSB resource.

[0132] The above-mentioned interference measurement resource can be an interference measurement resource of a serving cell (also referred to as a home cell) or an interference measurement resource of a supplementary cell (also referred to as a neighbor cell). The serving cell is a cell configured by the network device for the terminal for data transmission, and the network device configures all parameters of the serving cell to the terminal, and the terminal can independently perform data transmission through the serving cell. The supplementary cell is a cell configured by the network device for the terminal in addition to the serving cell. The supplementary cell can also be used for data transmission to a certain extent. The network device can not configure all parameters of the supplementary cell to the terminal device, but configure the information of the supplementary cell as a parameter of the serving cell to the terminal. In other words, the supplementary cell can work only by relying on its associated serving cell. The network device can configure one or more supplementary cells for the terminal, in other words, the serving cell can be associated with one or more supplementary cells, but only one supplementary cell is activated at the same time. The network device can perform joint transmission using one serving cell and the activated supplementary cell associated with the serving cell, which can also be referred to as cross-cell multi-TRP transmission.

[0133] The terminal can measure the above-mentioned K channel measurement resources to obtain measurement results corresponding to the K channel measurement resources.

[0134] The measurement results corresponding to the K channel measurement resources include CSI corresponding to the K channel measurement resources. The CSI includes one or more of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI) of a channel, a reference signal received power (RSRP), or a signal to interference plus noise ratio (SINR). The CSI can be wideband level CSI or subband level CSI. The PMI can be a type I PMI or a type II PMI. The present application does not limit this.

[0135] The terminal can also measure the M interference measurement resources to obtain measurement results corresponding to the M interference measurement resources, for example, the terminal can obtain channel information of the supplementary cell. The channel information specifically refers to channel information between each antenna port of the network device and each antenna port of the terminal, which can be represented by a matrix in mathematics. The channel matrix can be considered as an antenna domain channel matrix. Each element of the channel matrix represents the channel gain and phase between the i th antenna port of the network device and the j th antenna port of the terminal, where i and j are positive integers. The terminal can perform a discrete fourier transform (DFT) on the channel matrix to obtain a beam domain channel matrix. The beam domain channel matrix represents channel information between each beam of the network device and the terminal device. Through the beam domain channel matrix, the terminal can determine the interference caused by each beam of the network device to the terminal. The interference caused by each beam of the network device to the terminal is also called beam level interference, that is, interference quantified from the dimension of the beam.

[0136] In the present application, a beam can refer to a spatial basis, such as a DFT basis. The beam corresponding to the interference measurement resource refers to the spatial basis corresponding to the interference measurement resource. More specifically, the beam corresponding to the interference measurement resource refers to the spatial basis corresponding to the channel matrix corresponding to the interference measurement resource. For example, the DFT basis obtained by performing DFT on the channel matrix corresponding to the interference measurement resource.

[0137] Optionally, the method 400 further includes step 405: the network device sends first configuration information, the first configuration information being used for configuring the K channel measurement resources and the M interference measurement resources. Correspondingly, the terminal receives the first configuration information.

[0138] The K channel measurement resources can be configured in the same resource set or in independent resource sets, which is not limited in the application. Similarly, the M interference measurement resources can be configured in the same resource set or in independent resource sets.

[0139] Optionally, each of the M interference measurement resources is associated with a PCI.

[0140] The PCI can be a PCI of a serving cell or a PCI of a supplementary cell, which can be referred to as an additional PCI.

[0141] Table 1 shows the association between the interference measurement resources and the PCIs.

[0142] Table 1

[0143] As shown in Table 1, each interference measurement resource index is associated (or corresponds to or maps to) a PCI, for example, interference measurement resource 1 is associated with PCI 1, interference measurement resource 2 is associated with PCI 2, and interference measurement resource 3 is associated with PCI 3.

[0144] One possible design is that the PCIs 1, 2, 3, …, M have the same value, in other words, the M measurement resources are associated with the same PCI, that is, the M interference measurement resources can be used to measure the interference of the same cell corresponding to the associated PCI. For example, M = 3, the three interference measurement resources are interference measurement resource 1, interference measurement resource 2, and interference measurement resource 3, and the three interference measurement resources can be associated with the same PCI.

[0145] Another possible design is that the PCIs 1, 2, 3, …, M have different values, that is, the M interference measurement resources are associated with M different PCIs, or in other words, the M interference measurement resources and the M different PCIs are one-to-one correspondence, that is, the M interference measurement resources are used to measure the interference of M different cells. For example, M = 3, the three interference measurement resources are interference measurement resource 1, interference measurement resource 2, and interference measurement resource 3, interference measurement resource 1 is associated with PCI 1, interference measurement resource 2 is associated with PCI 2, and interference measurement resource 3 is associated with PCI 3, and PCI 1, PCI 2, and PCI 3 are different, that is, the three interference measurement resources are associated with three different PCIs.

[0146] In another possible design, some of the PCIs 1, 2, 3, …, M are the same and some of the PCIs 1, 2, 3, …, M are different, i.e., some of the M interference measurement resources are associated with the same PCI and another part of the M interference measurement resources can be associated with different PCIs. For example, M=3, the 3 interference measurement resources are interference measurement resource 1, interference measurement resource 2, and interference measurement resource 3, interference measurement resource 1 is associated with PCI 1, interference measurement resource 2 is associated with PCI 2, and interference measurement resource 3 is associated with PCI 3, the values of PCI 1 and PCI 2 are the same, and the values of PCI 3 and them are different.

[0147] The PCI includes the following three possible designs:

[0148] In a first possible design, the PCI is included in the configuration information corresponding to each of the M interference measurement resources.

[0149] In a second possible design, the PCI is included in the configuration information corresponding to the resource set to which the M interference measurement resources belong.

[0150] In a third possible design, the PCI is included in the reporting configuration corresponding to the M interference measurement resources.

[0151] In step 420, the terminal sends the measurement results, which include the measurement results corresponding to the Q channel measurement resources and the measurement results corresponding to the N interference measurement resources.

[0152] wherein N and Q are positive integers, N is less than or equal to M, and Q is less than or equal to K. For example, Q=1 and N=1. That is, the terminal measures K channel measurement resources, reports the measurement results corresponding to Q channel measurement resources, measures M interference measurement resources, and reports the measurement results corresponding to N interference measurement resources.

[0153] Optionally, the interference resource reporting mode used by the measurement results reported by the terminal includes a first reporting mode or a second reporting mode; when the interference resource reporting mode used by the measurement results is the first reporting mode, the measurement results include the measurement results of the interference measurement resource with the maximum interference strength on the Q channel measurement resources among the M interference measurement resources; when the interference resource reporting mode used by the measurement results is the second reporting mode, the measurement results include the measurement results of the interference measurement resource with the interference strength greater than or equal to a first threshold on the Q channel measurement resources among the M interference measurement resources.

[0154] The interference intensity of the interference measurement resource to the channel measurement resource can be the RSRP of the signal on the interference measurement resource, for example, the greater the RSRP, the greater the interference intensity.

[0155] The interference intensity of the interference measurement resource to the channel measurement resource can also be the corresponding CQI of the signal on the channel measurement resource under the interference of the interference measurement resource, for example, the greater the CQI, the smaller the interference intensity.

[0156] The interference intensity of the interference measurement resource to the channel measurement resource can also be the corresponding SINR of the signal on the channel measurement resource under the interference of the interference measurement resource, for example, the greater the SINR, the smaller the interference intensity.

[0157] Correspondingly, the interference intensity is greater than or equal to a first threshold, for example, the RSRP can be greater than or equal to a threshold 1, or the SINR can be less than or equal to a threshold 2, or the CQI can be less than or equal to a threshold 3, and so on.

[0158] It should be noted that in the present application, greater than or equal to and greater than can be replaced with each other, and similarly, less than or equal to can also be replaced with less than.

[0159] A possible case is that the terminal reports the measurement result in the first reporting mode, and the measurement result includes the measurement of the interference measurement resource with the greatest interference intensity to the Q channel measurement resources. As an example but not limitation, M=3, the interference intensity of the 3 interference measurement resources to the Q channel measurement resources is represented by the RSRP of the signal on the interference measurement resource, assuming that the RSRP of the signal on the interference measurement resource 1 is RSRP 1> RSRP of the signal on the interference measurement resource 2 RSRP 2> RSRP of the signal on the interference measurement resource 3 RSRP 3, the measurement result includes the measurement result corresponding to the interference measurement resource 1 in the measurement result.

[0160] Another possible case is that the terminal reports the measurement results in the second reporting mode, and the measurement results include measurement results of interference measurement resources that cause interference to the Q channel measurement resources greater than or equal to the first threshold value among the M interference measurement resources. By way of example but not limitation, M = 3, the interference strength of the 3 interference measurement resources to the Q channel measurement resources is represented by the corresponding SINR of the signals on the Q channel measurement resources under the interference of the 3 interference measurement resources, assuming that the average of the SINR of the Q channel measurement resources under the interference of the first interference measurement resource is SINR 1, the average of the SINR of the Q channel measurement resources under the interference of the second interference measurement resource is SINR 2, and the average of the SINR of the Q channel measurement resources under the interference of the third interference measurement resource is SINR 3, SINR 1 and SINR 2 are less than the first threshold value, then the measurement results include the measurement result corresponding to the first interference measurement resource and the measurement result corresponding to the second interference measurement resource.

[0161] It should be noted that in the present application, the average of the SINR of the signals on the Q channel measurement resources under the interference of the certain interference measurement resource is only an example, and should not constitute any limitation on the embodiments of the present application, for example, the SINR of the signals on the Q channel measurement resources under the interference of the certain interference measurement resource can also be the maximum value or weighted average of the corresponding SINR of the signals on each channel measurement resource, etc. Similarly, the RSRP or reference signal received quality (RSRQ) of the signals on the Q channel measurement resources under the interference of the certain interference measurement resource can also be processed in a similar manner, which is not limited in the present application.

[0162] Optionally, the method 400 further includes that the network device sends second configuration information for configuring the interference resource reporting mode for reporting the measurement results, and the interference resource reporting mode includes the first reporting mode or the second reporting mode. Correspondingly, the terminal receives the second configuration information.

[0163] When the network device configures the terminal to report the measurement result by using the interference resource reporting mode, the following rules can be followed: if the CSI corresponding to the measurement result is wideband-level CSI, the second configuration information configures the terminal to report the measurement result by using the first reporting mode; if the CSI corresponding to the measurement result is sub-band-level CSI, the second configuration information configures the terminal to report the measurement result by using the second reporting mode. Alternatively, if the second configuration information configures the terminal to report the measurement result by using the first reporting mode, the network device configures the CSI corresponding to the channel measurement resource in the measurement result to be wideband-level CSI; if the second configuration information configures the terminal to report the measurement result by using the second reporting mode, the network device configures the CSI corresponding to the channel measurement resource in the measurement result to be sub-band-level CSI.

[0164] The wideband-level CSI can be used to provide channel state information in the entire frequency spectrum, or used to provide channel state information of a frequency spectrum block greater than or equal to a certain frequency spectrum threshold; the sub-band-level CSI provides channel state information in a specific sub-band range, and can be used for fine-grained resource optimization. In this application, the wideband can refer to the entire frequency spectrum, or a frequency spectrum block greater than or equal to a certain frequency domain threshold, and the wideband can be divided into one or more sub-bands, and a sub-band can be composed of one or more contiguous physical resource blocks (PRBs).

[0165] In one possible implementation, the network device can configure the terminal to use the first reporting mode or the second reporting mode by using one parameter. As an example but not limitation, the parameter takes a value of 1 to indicate that the terminal uses the first reporting mode, and the parameter takes a value of 0 to indicate that the terminal does not use the first reporting mode, in other words, the terminal uses the second reporting mode.

[0166] In another possible implementation, the network device can configure the terminal to use the first reporting mode or the second reporting mode by using one parameter. As an example but not limitation, the parameter takes a value of 1 to indicate that the terminal uses the second reporting mode, and the parameter takes a value of 0 to indicate that the terminal uses the first reporting mode.

[0167] In yet another possible implementation, the network device can configure the terminal to use the first reporting mode or the second reporting mode by using one parameter. As an example but not limitation, the parameter takes a value of 1 to indicate that the terminal uses the first reporting mode, and the parameter takes a value of 0 to indicate that the terminal uses the second reporting mode.

[0168] Optionally, the interference resource reporting mode used for reporting the measurement result is determined by the terminal based on the type of the CSI, and the interference resource reporting mode includes the first reporting mode or the second reporting mode.

[0169] One possible way is that, if the CSI corresponding to the measurement result is wideband level CSI, the terminal determines that the measurement result is reported in the first reporting mode; if the CSI corresponding to the measurement result is subband level CSI, the terminal determines that the measurement result is reported in the second reporting mode.

[0170] Optionally, the terminal can report first capability information, which is used to indicate support of the first reporting mode or the second reporting mode.

[0171] One possible implementation is that the terminal can report whether the first reporting mode is supported. For example, the terminal can report whether the first reporting mode is supported by using 1 bit. For example, if the bit is 1, it indicates that the terminal supports the first reporting mode; if the bit is 0, it indicates that the terminal does not support the first reporting mode.

[0172] Another possible implementation is that the terminal can report whether the second reporting mode is supported. For example, the terminal can report whether the second reporting mode is supported by using 1 bit. For example, if the bit is 1, it indicates that the terminal supports the second reporting mode; if the bit is 0, it indicates that the terminal does not support the second reporting mode.

[0173] Yet another possible implementation is that the terminal can report whether the first reporting mode or the second reporting mode is supported. For example, the terminal can report whether the first reporting mode or the second reporting mode is supported by using 1 bit. For example, if the bit is 1, it indicates that the terminal supports the first reporting mode; if the bit is 0, it indicates that the terminal supports the second reporting mode.

[0174] Optionally, the value of N is predefined, or the value of N is configured by the network device, or the value of N is determined by the terminal device according to a rule.

[0175] One possible design is that the value of N is predefined, for example, the protocol specifies N = 1, in other words, the terminal device always reports the measurement result corresponding to one interference measurement resource.

[0176] Another possible design is that the value of N is configured by the network device, that is, the network device configures the terminal to report the measurement result corresponding to N interference measurement resources.

[0177] Yet another possible design is that the value of N is determined by the terminal device according to a rule, that is, the terminal determines the number of interference measurement resources for which the measurement result needs to be reported according to a rule.

[0178] Exemplarily, the N is a number of interference measurement resources whose interference intensities on the Q channel measurement resources are greater than or equal to a first threshold. That is, the terminal can report measurement results corresponding to the interference measurement resources whose interference intensities on the Q channel measurement resources are greater than or equal to the first threshold. In other words, for each of the M interference measurement resources, if the interference intensity of the interference measurement resource on the Q channel measurement resources is greater than or equal to the first threshold, the terminal reports the measurement result corresponding to the interference measurement resource; if the interference intensity of the interference measurement resource on the Q channel measurement resources is less than the first threshold, the terminal does not report the measurement result corresponding to the interference measurement resource.

[0179] Optionally, the N interference measurement resources include a first interference measurement resource, the first interference measurement resource is any one of the N interference measurement resources, and the interference beam reporting mode of the measurement result includes a third reporting mode or a fourth reporting mode; when the interference beam reporting mode of the measurement result is the third reporting mode, the measurement result includes information of a beam with the strongest interference on the Q channel measurement resources in the beams corresponding to the first interference measurement resource; when the interference beam reporting mode of the measurement result is the fourth reporting mode, the measurement result includes information of a beam with an interference intensity greater than or equal to a second threshold on the Q channel measurement resources in the beams corresponding to the first interference measurement resource.

[0180] It can be understood that the terminal device can determine the interference intensity of the Q channel measurement resources in the beams corresponding to the first interference measurement resource according to the channel matrix in the beam domain.

[0181] The information of the beam can include one or more of the following: an index of the beam, an intensity of the beam, or a CSI of the Q channel measurement resources under the interference of the beam. The index of the beam refers to index information used to represent the beam, such as an index of a spatial basis, or a plurality of index values used to represent a spatial basis, which can jointly represent a specific spatial basis.

[0182] A possible case is that the terminal reports the measurement result in the third reporting mode, and the measurement result includes information of a beam with the strongest interference on the Q channel measurement resources in the beams corresponding to the first interference measurement resource. As an example but not limitation, assuming that the beams corresponding to the first interference measurement resource include beam 1, beam 2, and beam 3, the interference intensity of beam 1 on the Q channel measurement resources > the interference intensity of beam 2 on the Q channel measurement resources > the interference intensity of beam 3 on the Q channel measurement resources, then the measurement result includes information of beam 1.

[0183] Another possible case is that the terminal reports the measurement result in the fourth reporting mode, and the measurement result includes information of beams corresponding to the first interference measurement resource and causing interference to the Q channel measurement resources greater than or equal to the second threshold. By way of example but not limitation, assuming that the beams corresponding to the first interference measurement resource include beam 1, beam 2, and beam 3, and the interference caused by beam 1 and beam 2 to the Q channel measurement resources is greater than the second threshold, the measurement result includes information of beam 1 and beam 2.

[0184] Optionally, the method 400 further includes that the network device sends third configuration information used for configuring an interference beam reporting mode adopted by the reporting of the measurement result, and the interference beam reporting mode includes the third reporting mode or the fourth reporting mode. Correspondingly, the terminal receives the third configuration information.

[0185] When the network device configures the interference beam reporting mode adopted by the reporting of the measurement result for the terminal, the following rules can be followed: if the CSI corresponding to the measurement result is wideband-level CSI, the third configuration information configures the reporting of the measurement result to adopt the third reporting mode; if the CSI corresponding to the measurement result is sub-band-level CSI, the third configuration information configures the reporting of the measurement result to adopt the fourth reporting mode. Alternatively, if the third configuration information configures the reporting of the measurement result to adopt the third reporting mode, the network device configures the CSI corresponding to the channel measurement resource in the measurement result to be wideband-level CSI; if the third configuration information configures the reporting of the measurement result to adopt the fourth reporting mode, the network device configures the CSI corresponding to the channel measurement resource in the measurement result to be sub-band-level CSI.

[0186] In the present application, the first configuration information, the second configuration information, and the third configuration information can be carried in the same signaling or in different signaling, or in other words, the first configuration information, the second configuration information, and the third configuration information can be configured by one configuration information, for example, the network device sends configuration information used for configuring the contents configured by the first configuration information, the second configuration information, and the third configuration information, and the present application does not limit this.

[0187] A possible implementation manner is that the network device can configure whether the terminal adopts the third reporting mode through one parameter. By way of example but not limitation, the parameter takes value 1 to indicate that the terminal adopts the third reporting mode, and the parameter takes value 0 to indicate that the terminal does not adopt the third reporting mode, in other words, the terminal adopts the fourth reporting mode.

[0188] In another possible implementation, the network device can configure whether the terminal adopts the fourth reporting mode through a parameter. By way of example but not limitation, the parameter takes a value of 1 to indicate that the terminal adopts the fourth reporting mode, and the parameter takes a value of 0 to indicate that the terminal does not adopt the fourth reporting mode, in other words, the terminal adopts the third reporting mode.

[0189] In yet another possible implementation, the network device can configure whether the terminal adopts the third reporting mode or the fourth reporting mode through a parameter. By way of example but not limitation, the parameter takes a value of 1 to indicate that the terminal adopts the third reporting mode, and the parameter takes a value of 0 to indicate that the terminal adopts the fourth reporting mode.

[0190] Optionally, the interference beam reporting mode for reporting the measurement result is determined by the terminal based on a type of channel state information, and the interference beam reporting mode includes the third reporting mode or the fourth reporting mode.

[0191] In one possible manner, if the CSI corresponding to the measurement result is wideband-level CSI, the third reporting mode is adopted for reporting the measurement result; and if the CSI corresponding to the measurement result is subband-level CSI, the fourth reporting mode is adopted for reporting the measurement result.

[0192] Optionally, the terminal can report second capability information, which is used to indicate support of the third reporting mode or the fourth reporting mode.

[0193] In one possible implementation, the terminal can report whether the third reporting mode is supported. By way of example, the terminal can report whether the third reporting mode is supported through a 1-bit bit. For example, the bit takes a value of 1 to indicate that the third reporting mode is supported by the terminal; and the bit takes a value of 0 to indicate that the third reporting mode is not supported by the terminal.

[0194] In another possible implementation, the terminal can report whether the fourth reporting mode is supported. By way of example, the terminal can report whether the fourth reporting mode is supported through a 1-bit bit. For example, the bit takes a value of 1 to indicate that the fourth reporting mode is supported by the terminal; and the bit takes a value of 0 to indicate that the fourth reporting mode is not supported by the terminal.

[0195] In yet another possible implementation, the terminal can report whether the third reporting mode or the fourth reporting mode is supported. By way of example, the terminal can report whether the third reporting mode or the fourth reporting mode is supported through a 1-bit bit. For example, the bit takes a value of 1 to indicate that the third reporting mode is supported by the terminal; and the bit takes a value of 0 to indicate that the fourth reporting mode is supported by the terminal.

[0196] Optionally, the measurement result comprises one or more of the following: the value of N, a first bitmap, information of the N interference measurement resources, a second bitmap corresponding to each of the N interference measurement resources, a number of beams corresponding to each of the N interference measurement resources, or information of the beams corresponding to each of the N interference measurement resources.

[0197] The value of N indicates the number of interference measurement resources for which the terminal reports measurement results. For example, if the terminal reports measurement results for one interference measurement resource, the value of N is 1.

[0198] Each bit in the first bitmap corresponds to an interference measurement resource, and each bit is used to indicate whether the measurement result includes the measurement result of the corresponding interference measurement resource. For example, a bit value of 1 indicates that the measurement result includes the measurement result of the corresponding interference measurement resource, and a bit value of 0 indicates that the measurement result does not include the measurement result of the corresponding interference measurement resource. For another example, a bit value of 1 indicates that the measurement result does not include the measurement result of the corresponding interference measurement resource, and a bit value of 0 indicates that the measurement result includes the measurement result of the corresponding interference measurement resource.

[0199] The information of the N interference measurement resources comprises one or more of the following: indices of the N interference measurement resources, interference strengths corresponding to the N interference measurement resources, or CSI of the Q channel measurement resources under the interference of the N interference measurement resources.

[0200] The interference strengths corresponding to the N interference measurement resources can be the RSRP of the signal on each interference measurement resource.

[0201] The CSI of the Q channel measurement resources under the interference of the N interference measurement resources, assuming that the N interference measurement resources include interference measurement resource 1 and interference measurement resource 2, comprises: CSI of the Q channel measurement resources under the interference of interference measurement resource 1 and CSI of the Q channel measurement resources under the interference of interference measurement resource 2. The CSI of the Q channel measurement resources under the interference of interference measurement resource 1 (or interference measurement resource 2) may, for example, be the average of the CQI of the Q channel measurement resources under the interference of interference measurement resource 1 (or interference measurement resource 2).

[0202] Each bit in the second bitmap corresponds to a beam of the interference measurement resource corresponding to the second bitmap, and is used to indicate whether the measurement result includes information of the beam. For example, a bit value of 1 indicates that the measurement result includes information of the beam, i.e., the beam is reported this time; a bit value of 0 indicates that the measurement result does not include information of the beam, i.e., the beam is not reported this time. For another example, a bit value of 1 indicates that the measurement result does not include information of the beam, i.e., the beam is not reported this time; a bit value of 0 indicates that the measurement result includes information of the beam, i.e., the beam is reported this time.

[0203] The number of beams corresponding to each of the N interference measurement resources is used to indicate the number of beams for which beam information is reported among the beams corresponding to the interference measurement resource. For example, if the measurement result includes information of 2 beams corresponding to the first interference measurement resource, the number of beams corresponding to the first interference measurement resource is 2. The measurement result can include the number of beams corresponding to the N interference measurement resources.

[0204] The information of the beams corresponding to each of the N interference measurement resources includes one or more of the following: an index of a beam, a strength of a beam, or a CSI of the Q channel measurement resources under the interference of each beam of the N interference measurement resources.

[0205] The index of a beam can refer to index information used to indicate the beam, such as an index of a spatial basis, or a plurality of index values used to represent a specific spatial basis. The strength of a beam can be obtained according to the beam-domain channel matrix mentioned above.

[0206] Optionally, the measurement result includes a first part and a second part, wherein the first part is used to indicate one or more of the following: a value of N, a first bitmap, and a number of beams corresponding to each of the N interference measurement resources; and the second part is used to indicate one or more of the following: information of the N interference measurement resources, a second bitmap corresponding to each of the N interference measurement resources, or information of the beams corresponding to each of the N interference measurement resources.

[0207] Exemplarily, when the interference resource reporting mode of the measurement result is the second reporting mode and / or the interference beam reporting mode of the measurement result is the fourth reporting mode, the measurement result can be reported in two parts, the first part is used to indicate one or more of the following: the value of N, a first bit bitmap, the number of beams corresponding to each of the N interference measurement resources; the second part is used to indicate one or more of the following: information of the N interference measurement resources, a second bit bitmap corresponding to each of the N interference measurement resources, or information of the beams corresponding to each of the N interference measurement resources.

[0266] When the CU includes the CU-CP and the CU-UP, the CU-CP is configured to implement the control plane functions of the CU, and the CU-UP is configured to implement the user plane functions of the CU. For example, the CU is configured to implement the functions of the PDCP layer, the RRC layer, and the SDAP layer, the CU-CP is configured to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is configured to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0267] The CU-CP can interact with the network element in the core network that is configured to implement the control plane functions. The network element in the core network that is configured to implement the control plane functions can be an access and mobility function network element, such as the access and mobility management function (AMF) network element in the 5G system. The AMF network element is configured to be responsible for the mobility management in the mobile network, such as the location update of the terminal device, the registration network of the terminal device, the handover of the terminal device, etc.

[0268] The CU-UP can interact with a network element in the core network for implementing user plane functions. The network element in the core network for implementing user plane functions, for example, a user plane function (UPF) network element in a 5G system, is responsible for forwarding and receiving data in the terminal device.

[0269] The above configurations of the CU and the DU are merely examples, and the functions of the CU and the DU can be configured as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to service types or other system requirements. For example, functions that require to meet a shorter delay requirement in processing time are arranged in the DU, and functions that do not require to meet the delay requirement are arranged in the CU.

[0270] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the intermediate radio frequency side.

[0271] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an open-CU (O-CU), the DU can also be referred to as an open-DU (O-DU), the CU-CP can also be referred to as an open-CU-CP (O-CU-CP), the CU-UP can also be referred to as an open-CU-UP (O-CU-UP), and the RU can also be referred to as an open-RU (O-RU). For the convenience of description, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description in this application. Any one of the CU (or the CU-CP, the CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0272] In the embodiment shown in FIG. 4, a specific implementation of step 405 can be that the DU corresponding to the network device sends the first configuration information through the RU, and in a design, the first configuration information is sent through the RRC layer of the network device. In the O-RAN system, a specific implementation of step 405 can be that the O-DU corresponding to the network device sends the first configuration information through the O-RU.

[0273] A specific implementation of step 420 can be that the DU corresponding to the network device receives the measurement result through the RU, and in a design, the measurement result can be received through the physical layer of the network device. In the O-RAN system, a specific implementation of step 420 can be that the O-DU corresponding to the network device receives the measurement result through the O-RU.
