Description

Interference reporting method, communication apparatus, storage medium and program product

[0001] The present application claims priority to the Chinese patent application No. 202411254245.7, filed on September 6, 2024, and entitled "Interference reporting method, communication apparatus, storage medium and program product", 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 program product. BACKGROUND

[0003] In a wireless communication system, a network device can send configuration information to a terminal through radio resource control (RRC) signaling for configuring channel measurement resources and related parameters of measurement result reporting. Accordingly, the terminal measures the channel measurement resources based on the above-mentioned configuration information and reports channel state information (CSI), and the network device formulates a scheduling strategy based on the above-mentioned CSI, and then the network device and the terminal perform transmission based on the above-mentioned scheduling strategy.

[0004] However, the transmission between the network device and the terminal can be affected by an interference signal, which 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. If the network device formulates a scheduling strategy based on the above-mentioned CSI, it can affect the transmission performance. SUMMARY

[0005] The present application provides an interference reporting method, a communication apparatus, a storage medium and a program product, in order to reduce interference and improve transmission performance.

[0006] In a first aspect, the present application provides an interference reporting method, which can be executed by a first communication apparatus. The first communication apparatus can be a terminal, a communication module in the terminal, a circuit or 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 system in package (SIP) chip containing a modem core), which is not limited by the present application. Hereinafter, the method is taken as an example executed by a terminal.

[0007] Exemplarily, the method comprises: measuring Q channel measurement resources and N interference measurement resources; and sending measurement results, the measurement results being used to indicate interference information corresponding to L channel measurement resources of the Q channel measurement resources, the interference information corresponding to the L channel measurement resources comprising information of interference measurement resources of the N interference measurement resources that interfere with the L channel measurement resources, Q, L and N being positive integers and Q being greater than or equal to L.

[0008] In the technical solution, the terminal can report the interference information corresponding to the L channel measurement resources of the Q channel measurement resources, so that the network device can determine the interference situation of the L channel measurement resources caused by the interference measurement resources, thereby optimizing the scheduling strategy, reducing the interference, and further improving the transmission performance.

[0009] Optionally, the measurement results further comprise information of P channel measurement resources of the Q channel measurement resources, wherein P is a positive integer and P is less than or equal to Q. In other words, the terminal can also report information of part or all of the channel measurement resources of the Q channel measurement resources, so that the network device can optimize the scheduling strategy based on the information of the channel measurement resources, thereby improving the transmission performance.

[0010] In a second aspect, the present application provides an interference reporting method, which can be executed by a second communication device. The second 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 limit the second communication device. Hereinafter, the method executed by the network device is taken as an example.

[0011] Exemplarily, the method comprises: sending reference signals corresponding to Q channel measurement resources and N interference measurement resources; and receiving measurement results, the measurement results being used to indicate interference information corresponding to L channel measurement resources of the Q channel measurement resources, the interference information corresponding to the L channel measurement resources comprising information of interference measurement resources of the N interference measurement resources that interfere with the L channel measurement resources, Q, L and N being positive integers and Q being greater than or equal to L.

[0012] In the technical solution, the network device can obtain the interference information corresponding to the L channel measurement resources of the Q channel measurement resources, so that the network device can determine the interference situation of the L channel measurement resources caused by the interference measurement resources, thereby optimizing the scheduling strategy, reducing the interference, and further improving the transmission performance.

[0013] In some possible implementation manners, the first channel measurement resource is included in the L channel measurement resources, and the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value, and / or the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource less than or equal to a second threshold value.

[0014] The first channel measurement resource is any one of the L channel measurement resources. In this application, greater than or equal to and greater than can be replaced with each other, and similarly, less than or equal to and less than can be replaced with each other. For example, the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value, which can be replaced with: the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than a first threshold value. For another example, the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource less than or equal to a second threshold value, which can be replaced with: the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource less than a second threshold value.

[0015] In addition, the information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value can be information of n interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value, n being a positive integer and n being less than or equal to N. That is, the information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value can be information of one or more interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold value.

[0016] For any one of the L channel measurement resources, the terminal can report information of interference measurement resources that cause interference greater than or equal to a first threshold value, or report information of interference measurement resources that cause interference less than or equal to a second threshold value, so that the network device obtains interference conditions of each channel measurement resource in the L channel measurement resources caused by the interference measurement resources, thereby optimizing the scheduling strategy, reducing interference, and further improving transmission performance.

[0017] In some possible implementation manners, in combination with the first aspect and the second aspect, each of the L channel measurement resources satisfies one or more of the following: there is at least one of the N interference measurement resources that causes interference to each of the L channel measurement resources greater than or equal to a first threshold; there is at least one of the N interference measurement resources that causes interference to each of the L channel measurement resources less than or equal to a second threshold; or, a signal quality of each of the L channel measurement resources is greater than or equal to a third threshold.

[0018] In the foregoing solution, a manner of how to select the L channel measurement resources is provided, so that the terminal determines the L channel measurement resources from the Q channel measurement resources, and then reports interference information corresponding to the L channel measurement resources.

[0019] In some possible implementation manners, in combination with the first aspect and the second aspect, the interference information corresponding to the L channel measurement resources includes L first information and / or L second information; each of the L first information corresponds to one of the L channel measurement resources, and each of the L first information is used to indicate information of an interference measurement resource that causes interference to the corresponding channel measurement resource greater than or equal to a first threshold; each of the L second information corresponds to one of the L channel measurement resources, and each of the L second information is used to indicate information of an interference measurement resource that causes interference to the corresponding channel measurement resource less than or equal to a second threshold.

[0020] That is, the measurement result can include the L first information and / or the L second information, and the reporting content that can be included in the measurement result is provided. Exemplarily, the terminal can report the L first information and / or the L second information to indicate interference information corresponding to each of the L channel measurement resources, so as to facilitate the network device to obtain interference conditions of each of the L channel measurement resources caused by the interference measurement resource, thereby optimizing a scheduling strategy, reducing interference, and further improving transmission performance.

[0021] In some possible implementation manners, in combination with the first aspect and the second aspect, one first information is a first bitmap, each bit in the first bitmap corresponds to one interference measurement resource, and each bit is used to indicate whether the corresponding interference measurement resource causes interference to the channel measurement resource corresponding to the first information greater than or equal to a first threshold; or, one first information is an index of an interference measurement resource that causes interference to the channel measurement resource corresponding to the first information greater than or equal to a first threshold from the N interference measurement resources.

[0022] That is, the L first information can be L first bitmaps, or indexes of L groups of interference measurement resources, providing various possible forms of first information, which is conducive to improving the flexibility of the terminal reporting interference information. Each index of the L groups of interference measurement resources can include an index of one or more of the N interference measurement resources.

[0023] In combination with the first aspect and the second aspect, in some possible implementation manners, one second information is a second bitmap, each bit in the second bitmap corresponding to an interference measurement resource, and each bit being used to indicate whether the corresponding interference measurement resource causes interference less than or equal to a second threshold to a channel measurement resource corresponding to the second information; or, one second information is an index of an interference measurement resource in the N interference measurement resources that causes interference less than or equal to the second threshold to the channel measurement resource corresponding to the second information.

[0024] That is, the L second information can be L second bitmaps, or indexes of L groups of interference measurement resources, providing various possible forms of second information, which is conducive to improving the flexibility of the terminal reporting interference information. Each index of the L groups of interference measurement resources can include an index of one or more of the N interference measurement resources.

[0025] Optionally, the L first information and / or the L second information are used to determine interference information corresponding to the L channel measurement resources.

[0026] That is, the network device can determine interference information corresponding to the L channel measurement resources based on the L first information and / or the L second information. For example, interference information corresponding to an i th channel measurement resource in the L channel measurement resources can be indicated by an i th first information / second information in the L first information / second information; in other words, the network device can determine interference information corresponding to an i th channel measurement resource in the L channel measurement resources by using an i th first information / second information in the L first information / second information, where i is a positive integer, and i is less than or equal to L.

[0027] In combination with the first aspect and the second aspect, in some possible implementation manners, the measurement result further includes first indication information, which is used to indicate the L channel measurement resources.

[0028] That is, the terminal can indicate interference information corresponding to which L channel measurement resources are reported, so as to facilitate the network device to determine the L channel measurement resources for which the corresponding interference information is reported.

[0029] In some possible implementation manners, the first indication information includes indexes of the L channel measurement resources, or the first indication information includes a third bitmap, each bit in the third bitmap corresponding to a channel measurement resource, and each bit being used to indicate whether interference information of the corresponding channel measurement resource is reported.

[0030] That is, the first indication information can be a third bitmap or indexes of the L channel measurement resources, and the first indication information provides multiple possible forms of the first indication, which is beneficial to improving flexibility of the terminal in indicating the L channel measurement resources.

[0031] Optionally, the first indication information is used by the network device to determine the channel measurement resource for which the interference information is reported.

[0032] That is, the network device can determine the L channel measurement resources for which the corresponding interference information is reported based on the first indication information.

[0033] In some possible implementation manners, the measurement result includes a first part (part 1) and a second part (part 2), the first part includes the first indication information, and the second part includes the L first information and / or the L second information.

[0034] In the scheme, the measurement result is reported in two parts, the first part can include relatively rough information, and the second part can include more detailed information, which is beneficial to determining, by the network device, whether more detailed measurement result is needed based on the relatively rough measurement result in the first part. This step-by-step refinement manner can improve feedback efficiency, and the system can respond to channel changes more quickly. In addition, it is beneficial to flexibly selecting whether to report detailed measurement result or rough measurement result according to actual demand and channel change, thereby optimizing use of feedback resources.

[0035] In a third aspect, a communication apparatus is provided, which includes a module for implementing the method in the first aspect and any possible implementation manner of the first aspect, or a module for implementing the method in the second aspect and any possible implementation manner of the second aspect. Each module can implement corresponding functions by executing computer programs or instructions.

[0064] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0065] The technical solutions provided in the present application can be applied to various communication systems, for example: a wireless local area network (WLAN), a wireless fidelity (Wi-Fi) system, 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).

[0066] The technical solutions provided in the present application can also be applied to future communication systems. The present application does not limit this.

[0067] In order to facilitate understanding of the method provided in the present application, the following points will be explained first.

[0068] First, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the same items or similar items with basically the same functions and effects are distinguished by using "first", "second", etc. For example, the first information and the second information are only used to distinguish different information, and the order is not limited. Those skilled in the art can understand that "first", "second", etc. do not limit the quantity and execution order, and "first", "second", etc. also do not necessarily mean different.

[0069] Second, in the embodiments shown in the present application, each term and English abbreviation, such as channel state information (CSI), a synchronization signal block (SSB), or a transmission configuration indication (TCI), is an example for convenient description, and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other terms that can achieve the same or similar functions in existing or future protocols.

[0070] Thirdly, the "protocol" involved in the embodiments of the present application can refer to a standard protocol in the communication field, which can include the LTE protocol, the NR protocol and the related protocol applied in the future communication system, and the present application does not limit this.

[0071] Fourthly, "at least one" refers to one or more, and "multiple" refers to two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three 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.

[0072] 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 a certain information is called 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 the 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; the to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is 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, the protocol defines), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that for the sender of the indication information, the indication information can be used to indicate the to-be-indicated information, and for the receiver of the indication information, the indication information can be used to determine the to-be-indicated information.

[0073] Sixthly, in the present application, the communication between different devices can refer to the direct communication between different devices (i.e. without the need of other devices to relay or forward), or can also refer to the communication between different devices through other devices (i.e. with the need of other devices to relay or forward), or can also refer to the communication between functional units inside a device through another functional unit and other devices. "Transmit" and "receive" represent the direction of signal transmission. For example, "transmit information to the terminal" can be understood as that the destination of the information is the terminal, which can include direct transmission through the air interface, and also includes indirect transmission through the air interface by other units or modules. "Receive configuration information from the network device" can be understood as that the source of the configuration information is the network device, which can include direct reception from the network device through the air interface, and also can include indirect reception from the network device through the air interface from other units or modules. "Transmit" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0074] In other words, transmission and reception can be between devices, for example, between network devices and terminals; or can be within a device, for example, between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0075] It can be understood that the information can be processed as necessary before being transmitted from the source to the destination, such as encoding, modulation, etc., and the destination can also perform corresponding processing after receiving the information from the source, such as decoding, demodulation, etc., so as to interpret the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0076] Seventhly, in the present application, "when", "in the case of", "if" and other descriptions all refer to the objective situation that the device (such as a network device or a terminal) will make corresponding processing, and are not limited to time, and also do not require the device (such as a network device or a terminal) to have a judgment action when implemented, and also do not mean that there are other limitations.

[0077] Eighth, the correspondence 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, and the present application does not limit. When configuring the correspondence relationship between the information and each parameter, it is not necessarily required to configure all the correspondence relationships shown in each table. For example, the correspondence 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, such as splitting, merging, etc. The names of the parameters shown in the titles of the above tables can also use other names understandable by the communication device, and the values or representations of the parameters can also use other values or representations understandable 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, etc.

[0078] Ninth, in the present application, predefined can also be understood as defined, predefined, stored, pre-stored, pre-negotiated, pre-configured, fixed, or pre-burned.

[0079] The communication system and scenarios to which the method provided in the present application is applicable will be described in detail below with reference to the accompanying drawings.

[0080] FIG. 1 is a schematic diagram of the architecture of a communication system applicable to the method provided in the present application. FIG. 1 shows a schematic diagram of a possible, non-limiting system architecture.

[0081] 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 (such as 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (such as 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), and each device can include different functional units. 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, or they can be the same physical device integrated with the logical functions of the core network and the logical functions of the wireless access network.

[0082] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4th generation (4G) mobile communication system, a 5G mobile communication system, or 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 Wi-Fi system. The RAN 100 can also be a communication system in which two or more of the above systems are fused.

[0083] 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 is configured to help terminals to access the network wirelessly. The RAN nodes 110 in the communication system 1000 can be of the same type or of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are opposite to each other, e.g., the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured as a mobile base station. For a terminal 120j that accesses 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 nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 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.

[0084] 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 Figure 1), a micro base station or an indoor station (e.g., 110b in Figure 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).

[0085] In another possible scenario, a terminal is assisted by multiple RAN nodes to implement wireless access in cooperation, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a centralized 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 also be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0086] 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.

[0087] The 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 device. The terminal is generally provided with a communication module, circuit or chip for performing corresponding communication functions. The terminal is also configured with program instructions for performing corresponding communication functions.

[0088] A terminal can access the above communication system and has a device or module with corresponding communication functions. For example, the terminal can be a device that provides voice / data connectivity to a user, such as a handheld device with wireless connection functions, a vehicle-mounted device, etc. Currently, some examples of terminals can be: a mobile phone, a tablet computer, a computer (such as a notebook computer, a palm computer, etc.) with wireless transceiver functions, 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 functions, 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 functions, a communication module, a terminal in a 5G network, or a terminal in a future evolved public land mobile network (PLMN), etc.

[0089] In addition, the terminal can also be a terminal in an internet of things (IoT) system. IoT is an important part of the future development of information technology, and its main technical feature is to connect objects through communication technology and network to realize the interconnection of man-machine and the interconnection of things. IoT technology can achieve massive connection, deep coverage, and terminal power saving through, for example, narrow band (NB) technology.

[0090] In addition, the terminal can also include smart printers, train detectors, gas station sensors, and the main functions include collecting data (part of the terminal), receiving control information and downlink data of network equipment, and sending electromagnetic waves to transmit uplink data to network equipment.

[0091] In the embodiments of the present application, the network device may, for example, be the RAN node 110 shown in FIG. 1, and the terminal may, for example, be the terminal 120 shown in FIG. 1. The type of the network device and the terminal is not limited in the present application.

[0092] In addition, the terminal and the network device may be hardware devices, or software functions running on special-purpose hardware, software functions running on general-purpose hardware, such as virtualized functions instantiated on a platform (e.g., a cloud platform), or entities including special-purpose or general-purpose hardware devices and software functions. The specific form of the terminal and the network device is not limited in the present application.

[0093] FIG. 2 is another architecture diagram of a communication system suitable for the method provided in the present application.

[0094] 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). As can be seen, one network device can transmit data or control signaling to one or more terminals.

[0095] 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). As can be seen, multiple network devices can transmit data or control signaling to one terminal.

[0096] 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, which are not limited in the embodiments of the present application. The network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell).

[0097] Optionally, the communication system shown in the communication system can include more network devices, and each network device can include other numbers of terminals within its coverage range, which are not limited in the embodiments of the present application.

[0098] It can be understood that the system architectures described in FIG. 1 and FIG. 2 are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application.

[0099] FIG. 3 is a scenario diagram suitable for the method provided in the present application.

[0100] As shown in FIG. 3, multiple network devices can send signals to multiple terminals, such as network device 1 sending signals to terminal 1, and network device 2 sending signals to terminal 2. The transmission between a network device and a terminal can be affected by an interference signal. The interference signal can be another signal sent by the network device, such as a signal sent by the network device to another terminal; or a signal sent 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.

[0101] An example is shown in FIG. 3. For a certain terminal, such as terminal 1, terminal 1 can be interfered by a signal from network device 2 when receiving a signal from network device 1, which can be referred to as inter-cell interference. Here, network device 1 and network device 2 can be in the same cell or in different cells, which is not limited in the present application.

[0102] Another example is shown in FIG. 3. For a certain terminal, such as terminal 1, terminal 1 can be interfered by a signal sent by network device 1 to terminal 2 when receiving a signal from network device 1, which can be referred to as intra-cell interference.

[0103] Currently, joint precoding can be used to reduce intra-cell interference. In more detail, when a network device is 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.

[0104] Similarly, inter-cell interference can also use joint precoding. In more detail, when multiple network devices are to send signals to multiple terminals, the multiple network devices jointly perform joint precoding processing, thereby reducing the interference between different cells, and making 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) in the signal received by the terminal.

[0105] With joint precoding, there can still be interference, which further affects the transmission performance. For example, in some scenarios, such as when the network devices cannot achieve ideal coordination, inter-cell interference can still exist, which further affects the transmission performance.

[0106] To this end, the application provides an interference reporting method. A terminal can report interference information corresponding to L channel measurement resources in Q channel measurement resources measured by the terminal, so that a network device can determine the interference situation of the L channel measurement resources by interference measurement resources, for example, the interference measurement resources can be interference measurement resources of a supplementary cell. In this way, the network device can determine the interference situation of the channel measurement resources of a serving cell by the interference measurement resources of the supplementary cell, thereby optimizing the scheduling strategy of the two cells to reduce inter-cell interference and improve transmission performance.

[0107] To facilitate understanding of the interference reporting method provided by the application, the terms involved in the application will be explained in detail first.

[0108] 1. Beam: can be understood as a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, quasi-colocation (QCL) information, a QCL assumption, a QCL indication, a transmission configuration indicator (TCI) state, a spatial relation, a spatial domain base, or a discrete fourier transform (DFT) base, etc. Therefore, in the present application, the concepts of beam, spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI state (including uplink TCI state or downlink TCI state), spatial relation, spatial domain base, or DFT base are equivalent, and the above concepts can be replaced with each other.

[0109] A beam used for transmitting a signal can be referred to as a transmission beam (Tx beam), and can also be referred to as a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. A downlink transmission beam can be indicated by a downlink TCI-state.

[0110] A beam used for receiving a signal can be referred to as a reception beam (Rx beam), and can also be referred to as a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting, etc.

[0111] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a reception beam can refer to a distribution of signal strength in different directions in space for a wireless signal received by an antenna.

[0112] In addition, a beam can be a wide beam or a narrow beam, or other types of beams. A technology for forming a beam can be a beamforming technology or other technologies. The beamforming technology can be a digital beamforming technology, an analog beamforming technology, or a hybrid digital / analog beamforming technology, etc. A beam can refer to an analog beam, a digital beam, or a hybrid of the two, i.e., a digital-analog combined beam generated by combining analog beam weights and digital beam weights.

[0113] A beam is generally corresponding to a resource. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal feeds back the quality of the measured resource, so that the network device knows the quality of the corresponding beam. In data transmission, the beam information can also be indicated through the corresponding resource. For example, the network device can indicate the downlink beam information of the terminal through the TCI field in the DCI.

[0114] Optionally, multiple beams with the same or similar communication characteristics are regarded as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals and the like. One or more antenna ports forming a beam can also be regarded as an antenna port set.

[0115] In the embodiments of the present application, if not specified, the beam refers to the transmitting beam of the network device. In beam measurement, each beam of the network device corresponds to a resource, so the beam corresponding to the resource can be uniquely identified by the index of the resource.

[0116] 2. Resource: In beam measurement, a beam can correspond to a resource, that is, there is a corresponding relationship between the beam and the resource (the network device transmits the corresponding resource by using one beam), and the terminal can consider that measuring the quality of the resource is equivalent to measuring the quality of the beam. The resource can be an uplink signal resource or a downlink signal resource. The uplink signal includes but is not limited to a sounding reference signal (SRS) and a demodulation reference signal (DMRS). The downlink signal includes but is not limited to a channel state information reference signal (CSI-RS), a cell-specific reference signal (CS-RS), a user equipment-specific reference signal (US-RS), a demodulation reference signal (DMRS), and a synchronization signal block (SSB) resource.

[0117] The resources are configured by RRC messages. In the configuration structure, one resource is an information element (IE) including the related parameters of its corresponding uplink / downlink reference signal, such as the type of the uplink / downlink reference signal, the resource granularity carrying the uplink / downlink reference signal, the transmission time and period of the uplink / downlink reference signal, the number of ports used for transmitting the uplink / downlink reference signal, and the like. Each uplink / downlink reference signal resource has a unique index to identify the reference signal resource. It can be understood that the index of the reference signal resource can also be referred to as the identification of the reference signal resource, and the embodiments of the present application do not make any limitation thereto.

[0118] It should be understood that the resources listed in the above are only exemplary descriptions, and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0119] 3. Beam management: mainly divided into downlink beam management and uplink beam management.

[0120] 1) Downlink beam management

[0121] The downlink beam management mainly includes the following steps:

[0122] S1, the network device sends measurement configuration information to the terminal device. The network device sends the measurement configuration information to the terminal through an RRC message, mainly including two parts: resource configuration information and reporting configuration information. The resource configuration information is the information related to the measurement resource, which is configured through a three-level structure (resourceConfig-resource set-resource) in the protocol. The network device can configure one or more resource configurations (also written as "resourceSetting") for the terminal, each resource configuration includes one or more resource sets, and each resource set can include one or more resources. Each resource configuration / resource set / resource includes its own index. In addition, some other parameters are also included, such as the period of the resource, the signal type corresponding to the resource, etc. The reporting configuration information refers to the information related to the reporting of the measurement result, which is configured through a reporting configuration (ReportConfig) in the protocol. The network device can configure one or more reporting configurations for the terminal, each reporting configuration includes reporting indicators, reporting time and period, reporting format and other information related to reporting. In addition, the reporting configuration also includes the index of the resource configuration, which is used to indicate that the reported result is measured through which measurement configuration. The following are the specific formats of the resource configuration and the reporting configuration in the R15 protocol, which are convenient for further understanding of the R15 measurement architecture. It should be understood that the formats shown below only show part of them, and more detailed configurations can be referred to R15. Among them, Table 1 is an example of resource configuration, and Table 2 is an example of reporting configuration.

[0123] Table 1

[0124] Table 2

[0125] S2, the network device sends a downlink signal on the resource corresponding to the resource configuration information, so that the terminal determines the quality of each resource (or the quality of the above downlink signal, or the quality of the resource corresponding to the beam) by measuring the downlink signal.

[0126] S3, the terminal measures the downlink signal according to the measurement configuration information.

[0127] S4, the terminal sends a beam measurement report to the network device. The beam measurement report can include the index of one or more resources, the quality of the resource, etc. Table 3 is the reporting format used by the beam measurement in the R15 protocol. Among them, the CSI-RS index (CRI) field and the SSB resource index (SSBRI) field are used to indicate the resource index to be reported. Only CRI or SSBRI can be reported, The other RSRP (differential RSRP in Table 3) field is reported with 4-bit quantization.

[0128] Table 3

[0129] The above information can be carried in a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0130] 2) Uplink beam management

[0131] The uplink beam management mainly includes the following steps:

[0132] S1, the network device sends SRS configuration information to the terminal. The network device can configure one or more SRS resource sets for the terminal for uplink beam management, each SRS resource set including one or more SRS resources. Each SRS resource is associated with a beam. Each SRS resource includes an SRS signal, and uplink beam measurement can be performed by measuring the SRS signals corresponding to the SRS resources. The specific format of the SRS resource configuration in the R15 protocol is shown below to facilitate further understanding of the R15 measurement architecture. It should be understood that the format shown below only shows part of it, and more detailed configurations can be referred to R15.

[0133] Table 4

[0134] S2, the terminal sends the corresponding SRS signal using the uplink transmission beam associated with each SRS resource according to the configuration of each SRS resource.

[0135] S3, the network device measures each SRS signal sent by the terminal and measures the quality of each SRS resource.

[0136] As can be known from the beam management process, the network device and the terminal can use a specific beam to communicate, and the specific beam used is determined by beam measurement. Illustratively, the network device can send downlink signals through each beam, each beam corresponding to a downlink signal, and the terminal determines a better quality beam based on the measurement of the above downlink signals.

[0137] The interference reporting method provided by the present application will be described in detail below with reference to the accompanying drawings. The method is described below by way of example of the interaction between a network device and a terminal, and 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 configured 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 core) responsible for the communication function in the terminal, etc.

[0138] FIG. 4 is a schematic flowchart of an interference reporting method 400 provided by an embodiment of the present application. The various steps in the method 400 will be described in detail below.

[0139] In step 410, the network device sends reference signals corresponding to Q channel measurement resources and N interference measurement resources. Correspondingly, the terminal receives the reference signals corresponding to the Q channel measurement resources and the N interference measurement resources. Each measurement resource (channel measurement resource or interference measurement resource) corresponds to a reference signal.

[0140] 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 (IM). Q and N are positive integers. For example, Q = 1 and N = 1, that is, the network device sends a reference signal corresponding to one channel measurement resource and a reference signal corresponding to one interference measurement resource. In the present application, the measurement resource (channel measurement resource or interference measurement resource) can refer to a configuration parameter in RRC configuration, which includes a parameter set or configuration unit corresponding to the reference signal for measurement. For example, one measurement resource can refer to a parameter set or configuration unit corresponding to one reference signal for measurement.

[0141] Optionally, the type of the channel measurement resource can be a non-zero power CSI-RS resource or an SSB resource. The type of the interference measurement resource can be a non-zero power CSI-RS resource, a zero power CSI-RS resource, a CSI-IM resource or an SSB resource. The present application does not limit the specific types of the channel measurement resource and the interference measurement resource.

[0142] In the present application, the N interference measurement resources can be interference measurement resources of a serving cell (may also be referred to as a current cell) or interference measurement resources of a supplementary cell (may also be referred to as a neighbor cell). When the N interference measurement resources are interference measurement resources of a supplementary cell, the N interference measurement resources can be interference measurement resources of one supplementary cell or interference measurement resources of multiple supplementary cells, which is not limited in the present application.

[0143] The serving cell can be understood as a cell configured by the network device for data transmission of the terminal. 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 can be understood as 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, 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 depending 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 by 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.

[0144] Optionally, the method 400 further includes step 405: the network device sends first configuration information, which is used to configure the Q channel measurement resources and the N interference measurement resources. Correspondingly, the terminal receives the first configuration information.

[0145] The Q channel measurement resources can be configured in the same resource set or in independent resource sets, which is not limited in the present application. Similarly, the N interference measurement resources can be configured in the same resource set or in independent resource sets. For example, when the N interference measurement resources are interference measurement resources of multiple supplementary cells, the N interference measurement resources can be configured in independent resource sets.

[0146] In this application, each channel measurement resource can correspond to one beam, or in other words, each channel measurement resource can be transmitted through one beam, or in other words, the reference signal corresponding to each channel measurement resource can be transmitted through one beam. Therefore, the beam and the channel measurement resource are equivalent and can be replaced with each other. Similarly, each interference measurement resource can correspond to one beam (which can be referred to as an interference beam), or in other words, each interference measurement resource can be transmitted through one interference beam, or in other words, the reference signal (which can be referred to as an interference signal) corresponding to each interference measurement resource can be transmitted through one interference beam. Therefore, the interference beam and the interference measurement resource are equivalent and can be replaced with each other.

[0147] Optionally, each of the N interference measurement resources is associated with one physical cell index (PCI).

[0148] The above-mentioned PCI can be the PCI of the serving cell or the PCI of the supplementary cell, wherein the PCI of the supplementary cell can be referred to as an additional PCI. If the configured interference measurement resource is associated with the PCI of the serving cell, the interference measurement resource is the interference measurement resource of the serving cell. If the configured interference measurement resource is associated with the PCI of the supplementary cell, the interference measurement resource is the interference measurement resource of the supplementary cell.

[0149] The following are several possible designs for each interference measurement resource being associated with one PCI:

[0150] One possible design is that the above-mentioned N interference measurement resources are associated with the same PCI, in other words, the above-mentioned N interference measurement resources can be used to measure the interference of the cells corresponding to the same PCI associated therewith, which helps to measure the interference strengths of different interference signals of the same cell.

[0151] Another possible design is that the above-mentioned N interference measurement resources are associated with N different PCIs, in other words, the above-mentioned N interference measurement resources and N different PCIs are one-to-one correspondence, that is, the above-mentioned N interference measurement resources are used to measure the interference of N different cells, which helps to measure the interference strengths of interference signals of multiple cells at a time and helps to measure a wider range of interference situations.

[0152] Still another possible design is that part of the above-mentioned N 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, both the interference strengths of different interference signals of a certain cell and the interference strengths of interference signals of multiple cells at a time can be measured.

[0153] In step 420, the terminal measures the Q channel measurement resources and the N interference measurement resources.

[0154] Wherein, the terminal measuring the channel measurement resource can be understood as the terminal measuring the reference signal on the channel measurement resource, or in other words, the terminal measuring the beam corresponding to the channel measurement resource; similarly, the terminal measuring the interference measurement resource can be understood as the terminal measuring the interference signal on the interference measurement resource, or in other words, the terminal measuring the interference beam corresponding to the interference measurement resource. Accordingly, the terminal measuring the channel measurement resource can obtain the quality of the channel measurement resource, that is, the quality of the beam corresponding to the channel measurement resource, and similarly, the terminal measuring the interference measurement resource can obtain the quality of the interference measurement resource, that is, the quality of the interference beam corresponding to the interference measurement resource.

[0155] Alternatively, in addition, in the present application, the parameters for measuring the quality of the beam include received signal strength indicator (RSSI), reference signal received power (RSRP), etc., but are not limited thereto. For example, the quality of the beam can also be measured by reference signal received quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR, simply referred to as signal-to-interference ratio), precoding matrix indicator (PMI), transmitted precoding matrix indicator (TPMI), rank indicator (RI), transmitted rank indicator (TRI), layer indicator (LI), timing advance (TA), etc.

[0156] The terminal measures the Q channel measurement resources and the N interference measurement resources. One possible implementation is that the terminal can measure the Q channel measurement resources to obtain the quality of the Q channel measurement resources, that is, to obtain the quality of the Q beams corresponding to the Q channel measurement resources, and further determine the interference information corresponding to the Q channel measurement resources.

[0157] The measurement results corresponding to the Q channel measurement resources include CSI corresponding to the Q channel measurement resources. The CSI includes one or more of a channel quality indicator (CQI), a PMI, an RI, an RSRP, or an SINR, and the like. 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 the CSI or the PMI.

[0158] It can be understood that the terminal can also measure a larger number of channel measurement resources (such as M, M > Q), determine Q channel measurement resources from the M channel measurement resources, and the Q channel measurement resources are Q channel measurement resources with better quality from the M channel measurement resources.

[0159] After the terminal determines the quality of the Q channel measurement resources, the terminal can further determine the interference information corresponding to the Q channel measurement resources. Taking any channel measurement resource (denoted as a second channel measurement resource) from the Q channel measurement resources as an example, the terminal can determine the interference information of the N interference measurement resources on the second channel measurement resource by measuring the N interference measurement resources.

[0160] In a possible design, the interference information of the N interference measurement resources on the second channel measurement resource is information of an interference measurement resource from the N interference measurement resources that causes interference on the second channel measurement resource greater than or equal to a first threshold. For example, any interference measurement resource (such as a first interference measurement resource) causes interference on the second channel measurement resource greater than or equal to the first threshold, which can mean that the signal quality of the first interference measurement resource is greater than or equal to a first preset threshold, or the difference between the signal quality of the second channel measurement resource and the signal quality of the first interference measurement resource (such as the signal quality of the second channel measurement resource minus the signal quality of the first interference measurement resource) is less than or equal to a second preset threshold, or the SINR / CQI of the second channel measurement resource under the interference of the first interference measurement resource is less than or equal to a third preset threshold.

[0161] The signal quality of the first interference measurement resource being greater than or equal to a first preset threshold can be understood as that the signal quality of the first interference measurement resource received by the terminal using the receiving beam of the second channel measurement resource is greater than or equal to the first preset threshold. The difference between the signal quality of the second channel measurement resource and the signal quality of the first interference measurement resource being less than or equal to a second preset threshold can be understood as that the difference between the signal quality of the second channel measurement resource received by the terminal using the receiving beam of the second channel measurement resource and the signal quality of the first interference measurement resource received by the terminal using the receiving beam of the second channel measurement resource is less than or equal to the second preset threshold.

[0162] As mentioned above, the resource can be replaced by a beam. Exemplarily, the second channel measurement resource corresponds to a second beam, and the terminal determines information of any one of N interference beams (denoted as a first interference beam) corresponding to the N interference measurement resources, which causes interference to the second beam greater than or equal to a first threshold. The first interference beam causes interference to the second beam greater than or equal to the first threshold, for example, can mean that the signal quality of the first interference beam is greater than or equal to a first preset threshold, or the difference between the signal quality of the second beam and the signal quality of the first interference beam (such as the signal quality of the second beam minus the signal quality of the first interference beam) is less than or equal to a second preset threshold, or the SINR / CQI of the second beam under the interference of the first interference beam is less than or equal to a third preset threshold.

[0163] The signal quality of the first interference beam being greater than or equal to a first preset threshold can be understood as that the signal quality of the first interference beam received by the terminal using the receiving beam of the second beam is greater than or equal to the first preset threshold. The difference between the signal quality of the second beam and the signal quality of the first interference beam being less than or equal to a second preset threshold can be understood as that the difference between the signal quality of the second beam received by the terminal using the receiving beam of the second beam and the signal quality of the first interference beam received by the terminal using the receiving beam of the second beam is less than or equal to the second preset threshold.

[0164] In another possible design, the interference information of the N interference measurement resources on the second channel measurement resource refers to information of an interference measurement resource of the N interference measurement resources that causes interference on the second channel measurement resource less than or equal to a second threshold. For example, any interference measurement resource (denoted as a first interference measurement resource) of the N interference measurement resources causes interference on the second channel measurement resource less than or equal to the second threshold, which can refer to that a signal quality of the first interference measurement resource is less than or equal to a fourth preset threshold, or a difference (e.g., a signal quality of the second channel measurement resource - a signal quality of the first interference measurement resource) between a signal quality of the second channel measurement resource and a signal quality of the first interference measurement resource is greater than or equal to a fifth preset threshold, or a SINR / CQI of the second channel measurement resource under interference of the first interference measurement resource is greater than or equal to a sixth preset threshold.

[0165] For example, the signal quality of the first interference measurement resource less than or equal to the fourth preset threshold can refer to that a signal quality of the first interference measurement resource received by the terminal using a receiving beam of the second channel measurement resource is less than or equal to the fourth preset threshold. The difference between the signal quality of the second channel measurement resource and the signal quality of the first interference measurement resource greater than or equal to the fifth preset threshold can refer to that a difference between a signal quality of the second channel measurement resource received by the terminal using the receiving beam of the second channel measurement resource and a signal quality of the first interference measurement resource received by the terminal using the receiving beam of the second channel measurement resource is greater than or equal to the fifth preset threshold.

[0166] As mentioned above, the resource can be replaced by a beam. For example, the second channel measurement resource corresponds to a second beam, and the terminal determines information of an interference beam of the N interference beams that causes interference on the second beam less than or equal to a second threshold. For example, any interference beam (denoted as a first interference beam) of the N interference beams causes interference on the second beam less than or equal to the second threshold, which can refer to that a signal quality of the first interference beam is less than or equal to a fourth preset threshold, or a difference (e.g., a signal quality of the second beam - a signal quality of the first interference beam) between a signal quality of the second beam and a signal quality of the first interference beam is greater than or equal to a fifth preset threshold, or a SINR / CQI of the second beam under interference of the first interference beam is greater than or equal to a sixth preset threshold.

[0167] The signal quality of the first interference beam is less than or equal to a fourth preset threshold, which can be understood as that the signal quality of the first interference beam received by the terminal using the receiving beam of the second beam is less than or equal to the fourth preset threshold. A difference between the signal quality of the second beam and the signal quality of the first interference beam received by the terminal using the receiving beam of the second beam is greater than or equal to a fifth preset threshold, which can be understood as that the difference between the signal quality of the second beam and the signal quality of the first interference beam received by the terminal using the receiving beam of the second beam is greater than or equal to the fifth preset threshold.

[0168] It should be understood that the first to sixth preset thresholds and the first and second thresholds can be predefined or indicated by the network device, and the specific values of the first to sixth preset thresholds and the first and second thresholds are not limited in the present application. In addition, the first to sixth preset thresholds and the first and second thresholds can have the same value, part of the same value, or all different values, and the specific values of the first to sixth preset thresholds and the first and second thresholds are not limited in the present application.

[0169] In step 430, the terminal sends a measurement result, which is used to indicate interference information corresponding to L channel measurement resources in the Q channel measurement resources. Correspondingly, the network device receives the measurement result.

[0170] The interference information corresponding to the L channel measurement resources includes information of interference measurement resources in the N interference measurement resources that cause interference to the L channel measurement resources, L is a positive integer, and Q is greater than or equal to L.

[0171] The interference information corresponding to the L channel measurement resources includes interference information corresponding to each channel measurement resource in the L channel measurement resources, in other words, each channel measurement resource in the L channel measurement resources corresponds to one interference information. Taking any channel measurement resource (denoted as a first channel measurement resource) in the L channel measurement resources as an example, the interference information corresponding to the first channel measurement resource can be information of interference measurement resources in the N interference measurement resources that cause interference to the first channel measurement resource.

[0172] Optionally, the terminal determines the L channel measurement resources from the Q channel measurement resources. In one possible implementation, each channel measurement resource in the L channel measurement resources satisfies one or more of the following conditions: there is at least one interference measurement resource in the N interference measurement resources that causes interference to each channel measurement resource greater than or equal to a first threshold; there is at least one interference measurement resource in the N interference measurement resources that causes interference to each channel measurement resource less than or equal to a second threshold; or, the signal quality of each channel measurement resource is greater than or equal to a third threshold.

[0173] For example, taking any one of the L channel measurement resources (denoted as a first channel measurement resource) as an example, the first channel measurement resource satisfies one or more of the following: there is at least one of the N interference measurement resources that causes interference to the first channel measurement resource greater than or equal to a first threshold (which can be considered as causing strong interference to the first channel measurement resource); there is at least one of the N interference measurement resources that causes interference to the first channel measurement resource less than or equal to a second threshold (which can be considered as causing weak interference to the first channel measurement resource); or, a signal quality of the first channel measurement resource is greater than or equal to a third threshold. In other words, for any one of the Q channel measurement resources, as long as it satisfies one or more of the above conditions, the channel measurement resource is included in the L channel measurement resources for reporting.

[0174] One possible implementation is that, for any one of the Q channel measurement resources (denoted as a second channel measurement resource), the terminal determines interference caused by each of the N interference measurement resources to the second channel measurement resource. If there is at least one of the N interference measurement resources that causes interference to the second channel measurement resource greater than or equal to a first threshold, the second channel measurement resource belongs to one of the L channel measurement resources; if there is no interference measurement resource of the N interference measurement resources that causes interference to the second channel measurement resource greater than or equal to the first threshold (or if the interference caused by the N interference measurement resources to the second channel measurement resource is less than the first threshold), the second channel measurement resource does not belong to the L channel measurement resources.

[0175] Another possible implementation is that, for any one of the Q channel measurement resources (denoted as a second channel measurement resource), the terminal determines interference caused by each of the N interference measurement resources to the second channel measurement resource. If there is at least one of the N interference measurement resources that causes interference to the second channel measurement resource less than or equal to a second threshold, the second channel measurement resource belongs to one of the L channel measurement resources; if there is no interference measurement resource of the N interference measurement resources that causes interference to the second channel measurement resource less than or equal to the second threshold (or if the interference caused by the N interference measurement resources to the second channel measurement resource is greater than the second threshold), the second channel measurement resource does not belong to the L channel measurement resources.

[0176] Another possible implementation is that, for the second channel measurement resource, if the signal quality of the second channel measurement resource is greater than or equal to a third threshold, the second channel measurement resource belongs to one of the L channel measurement resources; if the signal quality of the second channel measurement resource is less than the third threshold, the second channel measurement resource does not belong to the L channel measurement resources.

[0177] Another possible implementation is that, for the second channel measurement resource, if the signal quality of the second channel measurement resource is greater than or equal to a third threshold, further determine the interference caused by each of the N interference measurement resources to the second channel measurement resource, if there is at least one of the N interference measurement resources causing interference to the second channel measurement resource greater than or equal to a first threshold, the second channel measurement resource belongs to one of the L channel measurement resources; if there is no interference measurement resource in the N interference measurement resources causing interference to the second channel measurement resource greater than or equal to the first threshold, the second channel measurement resource does not belong to the L channel measurement resources. If the signal quality of the second channel measurement resource is less than the third threshold, the second channel measurement resource does not belong to the L channel measurement resources. Here, it is not listed one by one.

[0178] Taking any one of the L channel measurement resources (denoted as a first channel measurement resource) as an example, the interference information corresponding to the first channel measurement resource, one possible design is that the interference information corresponding to the first channel measurement resource includes: information of the interference measurement resources in the N interference measurement resources causing interference to the first channel measurement resource greater than or equal to a first threshold.

[0179] Another possible design is that the interference information corresponding to the first channel measurement resource includes: information of the interference measurement resources in the N interference measurement resources causing interference to the first channel measurement resource less than or equal to a second threshold.

[0180] It can be understood that the above two possible designs can be used in combination or separately. When the above two possible designs are used in combination, the interference information corresponding to the first channel measurement resource includes: information of the interference measurement resources in the N interference measurement resources causing interference to the first channel measurement resource greater than or equal to a first threshold, and information of the interference measurement resources in the N interference measurement resources causing interference to the first channel measurement resource less than or equal to a second threshold.

[0181] 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 and less than can be replaced with each other. For example, the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference greater than or equal to the first threshold to the first channel measurement resource, which can be replaced with: the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference greater than the first threshold to the first channel measurement resource. For another example, the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference less than or equal to the second threshold to the first channel measurement resource, which can be replaced with: the interference information corresponding to the first channel measurement resource includes information of interference measurement resources in the N interference measurement resources that cause interference less than the second threshold to the first channel measurement resource.

[0182] In addition, the information of interference measurement resources in the N interference measurement resources that cause interference greater than or equal to the first threshold to the first channel measurement resource can be information of n interference measurement resources in the N interference measurement resources that cause interference greater than or equal to the first threshold to the first channel measurement resource, n being a positive integer and n being less than or equal to N. That is, the information of interference measurement resources in the N interference measurement resources that cause interference greater than or equal to the first threshold to the first channel measurement resource can be information of one or more interference measurement resources in the N interference measurement resources that cause interference greater than or equal to the first threshold to the first channel measurement resource.

[0183] The information of the interference measurement resource can include one or more of the following: an index of the interference measurement resource, or an interference intensity of the interference measurement resource to the first channel measurement resource. The interference intensity of the interference measurement resource to the first channel measurement resource can be, for example, an RSRP of a signal on the interference measurement resource, for example, the greater the RSRP, the greater the interference of the interference measurement resource to the first channel measurement resource. The interference intensity of the interference measurement resource to the first channel measurement resource can also be a corresponding CQI of a signal on the first channel measurement resource under the interference of the interference measurement resource, for example, the greater the CQI, the smaller the interference intensity. The interference intensity of the interference measurement resource to the first channel measurement resource can also be a corresponding SINR of a signal on the first channel measurement resource under the interference of the interference measurement resource, for example, the greater the SINR, the smaller the interference intensity.

[0184] The content included in the measurement result reported by the terminal will be described in detail below.

[0185] The measurement result can include one or more of the following: information of P channel measurement resources in the Q channel measurement resources, first indication information, or interference information corresponding to the L channel measurement resources.

[0186] wherein P is a positive integer, P is less than or equal to Q, in other words, the terminal can also report information of part or all of the Q channel measurement resources. The information of the P channel measurement resources, for example, includes indexes of the P channel measurement resources and / or qualities of the P channel measurement resources. The qualities of the P channel measurement resources, for example, can be CSIs of the P channel measurement resources.

[0187] The first indication information is used to indicate the L channel measurement resources. That is, the terminal can indicate which L channel measurement resources correspond to the interference information reported by the terminal, so as to enable the network device to determine the L channel measurement resources corresponding to the interference information reported by the terminal. In other words, the first indication information can be used by the network device to determine the channel measurement resources corresponding to the interference information reported by the terminal. That is, the network device can determine the L channel measurement resources corresponding to the interference information reported by the terminal based on the first indication information.

[0188] Optionally, the information of the P channel measurement resources in the Q channel measurement resources, the first indication information, or the interference information corresponding to the L channel measurement resources are carried in the same signaling, but this should not constitute any limitation to the present application. For example, the information of the P channel measurement resources in the Q channel measurement resources, the first indication information, or the interference information corresponding to the L channel measurement resources can also be carried in different signaling, that is, the above contents can also be sent separately. One possible design is that the first indication information includes indexes of the L channel measurement resources.

[0189] Another possible design is that the first indication information includes a third bit map, each bit in the third bit map corresponds to a channel measurement resource, and each bit is used to indicate whether the interference information of the corresponding channel measurement resource is reported. For example, a bit value of 1 indicates that the measurement result includes the interference information of the channel measurement resource; a bit value of 0 indicates that the measurement result does not include the interference information of the channel measurement resource. For another example, a bit value of 1 indicates that the measurement result does not include the interference information of the channel measurement resource; a bit value of 0 indicates that the measurement result includes the interference information of the channel measurement resource.

[0190] The interference information corresponding to the L channel measurement resources can include one or more of the following: L first information, L second information; each of the L first information corresponds to one of the L channel measurement resources, and each of the first information is used to indicate information of an interference measurement resource causing interference greater than or equal to a first threshold to the corresponding channel measurement resource; each of the L second information corresponds to one of the L channel measurement resources, and each of the second information is used to indicate information of an interference measurement resource causing interference less than or equal to a second threshold to the corresponding channel measurement resource.

[0191] That is, the measurement result can include L first information and / or L second information.

[0192] In one example, the measurement result includes L first information, and each of the first information is used to indicate information of an interference measurement resource causing interference greater than or equal to a first threshold to the channel measurement resource corresponding to the first information among the N interference measurement resources.

[0193] In another example, the measurement result includes L second information, and each of the second information is used to indicate information of an interference measurement resource causing interference less than or equal to a second threshold to the channel measurement resource corresponding to the first information among the N interference measurement resources.

[0194] In yet another example, the measurement result includes L first information and L second information, each of the first information is used to indicate information of an interference measurement resource causing interference greater than or equal to a first threshold to the channel measurement resource corresponding to the first information among the N interference measurement resources; and each of the second information is used to indicate information of an interference measurement resource causing interference less than or equal to a second threshold to the channel measurement resource corresponding to the first information among the N interference measurement resources.

[0195] As to the reporting form of the first information, one possible design is that one first information is a first bitmap, each bit in the first bitmap corresponds to one interference measurement resource, and each bit is used to indicate whether the corresponding interference measurement resource causes interference greater than or equal to a first threshold to the channel measurement resource corresponding to the first information. That is, each of the L first information corresponds to a first bitmap, and the L first information includes the L first bitmaps. For example, a bit value of 1 indicates that the corresponding interference measurement resource causes interference greater than or equal to the first threshold to the channel measurement resource corresponding to the first information; and a bit value of 0 indicates that the corresponding interference measurement resource causes interference less than the first threshold to the channel measurement resource corresponding to the first information. For another example, a bit value of 1 indicates that the corresponding interference measurement resource causes interference less than the first threshold to the channel measurement resource corresponding to the first information; and a bit value of 0 indicates that the corresponding interference measurement resource causes interference greater than or equal to the first threshold to the channel measurement resource corresponding to the first information.

[0196] Another possible design is that one first information is an index of an interference measurement resource in the N interference measurement resources that causes interference greater than or equal to a first threshold to the channel measurement resource corresponding to the first information. That is, each of the L first information corresponds to an index of a group of interference measurement resources, the number of indexes in the index of the group of interference measurement resources can be one or more, and the L first information includes L indexes of groups of interference measurement resources.

[0197] As to the reporting form of the second information, one possible design is that one second information is a second bitmap, each bit in the second bitmap corresponds to one interference measurement resource, and each bit is used to indicate whether the corresponding interference measurement resource causes interference less than or equal to a second threshold to the channel measurement resource corresponding to the second information. That is, each of the L second information corresponds to a second bitmap, and the L second information includes the L second bitmaps. For example, a bit value of 1 indicates that the corresponding interference measurement resource causes interference less than or equal to the second threshold to the channel measurement resource corresponding to the second information; and a bit value of 0 indicates that the corresponding interference measurement resource causes interference greater than the second threshold to the channel measurement resource corresponding to the second information. For another example, a bit value of 1 indicates that the corresponding interference measurement resource causes interference greater than the second threshold to the channel measurement resource corresponding to the second information; and a bit value of 0 indicates that the corresponding interference measurement resource causes interference less than or equal to the second threshold to the channel measurement resource corresponding to the second information.

[0198] Another possible design is that each of the L second information corresponds to a set of indexes of the interference measurement resources, and the number of indexes in the set of indexes can be one or more. The L second information includes L sets of indexes of the interference measurement resources.

[0199] It can be understood that when the measurement result includes the L first information and the L second information, each of the L first information can be a first bitmap, each of the L second information can be a second bitmap, each of the L first information can be a set of indexes of the interference measurement resources, each of the L second information can be a set of indexes of the interference measurement resources, each of the L first information can be a first bitmap and each of the L second information can be a set of indexes of the interference measurement resources, or each of the L first information can be a set of indexes of the interference measurement resources and each of the L second information can be a second bitmap. The present application does not limit this, for example, part of the L first information can be in the form of a first bitmap and the rest of the first information can be in the form of a set of indexes of the interference measurement resources, which is not listed one by one here. Optionally, the L first information and / or the L second information are used to determine the interference information corresponding to the L channel measurement resources.

[0200] That is, the network device can determine the interference information corresponding to the L channel measurement resources based on the L first information and / or the L second information. For example, the interference information corresponding to the i-th channel measurement resource in the L channel measurement resources can be indicated by the i-th first information / second information in the L first information / second information. In other words, the network device can determine the interference information corresponding to the i-th channel measurement resource in the L channel measurement resources by the i-th first information / second information in the L first information / second information, where i is a positive integer and i is less than or equal to L.

[0201] Optionally, the measurement result includes a first part (part 1) and a second part (part 2), where the first part includes the first indication information, and the second part includes the L first information and / or the L second information. The network device can determine which L channel measurement resources the terminal reports the interference information corresponding to according to the first part, and further determine the interference information corresponding to the L channel measurement resources according to the second part.

[0202] Optionally, the first part can further comprise information of P channel measurement resources of the Q channel measurement resources.

[0203] In the above scheme, the measurement result is reported in two parts, 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 result is needed according to the relatively rough measurement result of the first part. This step-by-step refinement method can improve the feedback efficiency, so that the system can respond to channel changes more quickly. In addition, it is helpful to flexibly select whether to report detailed measurement result or rough measurement result according to actual demand and channel change situation, thereby optimizing the use of feedback resources.

[0244] FIG. 8 is a schematic diagram of an O-RAN system according to an embodiment of the present application. The O-RAN system can also include other components in addition to the components shown in FIG. 8.

[0245] As shown in FIG. 8, the network device in the embodiments of the present application can also be referred to as an access network device. The access network device (i.e., RAN, which can be an eNB or a gNB or a next-generation access network device) can communicate with a core network (CN) through a backhaul and can communicate with a terminal through an air interface.

[0246] Specifically, the BBU in the access network device can communicate with the core network device through a backhaul, and the RU in the access network device can communicate with at least one terminal through an air interface. The BBU can communicate with at least one RU through a front haul, and the BBU and the RU can be co-located or not.

[0247] The BBU includes at least one centralized unit (CU) and at least one distributed unit (DU), which can communicate through at least one midhaul.

[0248] FIG. 9 is a schematic diagram of an access network device suitable for the interference reporting method provided by the present application. As shown in FIG. 9, the access network device includes one or more CUs, one or more DUs, and one or more RUs, and for the sake of clarity, only one CU, one DU, and one RU are shown in FIG. 9. The CU is configured to be connected to the core network and one or more DUs. Optionally, the CU can have part of the functions of the core network. The CU can include a CU-CP and a CU-UP.

[0249] The CU and the DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and above protocol layers (such as the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the PDCP layer and below protocol layers (such as the radio link control (RLC) layer, the medium access control (MAC) layer, and / or the physical (PHY) layer, etc.). For another example, the CU is configured to implement the functions of the PDCP layer and above protocol layers (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and below protocol layers (such as the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0250] When the CU includes the CU-CP and the CU-UP, the CU-CP is configured to implement the control plane function of the CU, and the CU-UP is configured to implement the user plane function of the CU. For example, when 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 function and the control plane function of the PDCP layer, and the CU-UP is configured to implement the SDAP layer function and the user plane function of the PDCP layer.

[0251] The CU-CP can interact with a network element in the core network configured to implement the control plane function. The network element in the core network configured to implement the control plane function can be an access and mobility function network element, such as an access and mobility management function (AMF) network element in a 5G system. The AMF network element is configured to be responsible for mobility management in the mobile network, such as location update of the terminal device, registration network of the terminal device, handover of the terminal device, and the like.

[0252] The CU-UP can interact with a network element in the core network configured to implement the user plane function. The network element in the core network configured to implement the user plane function, such as a user plane function (UPF) network element in a 5G system, is configured to be responsible for forwarding and receiving data in the terminal device.

[0253] The above configuration of the CU and the DU is only an example, and the CU and the DU can be configured to have other functions according to needs. For example, the CU or the DU can be configured to have more functions of protocol layers, or the CU or the DU can be configured to have partial processing functions of protocol layers. For example, partial functions of the RLC layer and functions of protocol layers above the RLC layer are configured in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are configured 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 need to meet a relatively low latency requirement in processing time are configured in the DU, and functions that do not need to meet the latency requirement are configured in the CU.

[0254] The DU and the RU can cooperate to 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 various 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-level functions in the PHY layer, and the RU is configured to implement low-level functions in the PHY layer or to implement the low-level functions and radio frequency functions. The high-level functions in the PHY layer can include part of the functions of the PHY layer that are closer to the MAC layer, and the low-level 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.

[0255] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the 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, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and 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.

[0256] In the embodiment shown in FIG. 4, the specific implementation of step 405 can be that the DU corresponding to the network device sends the first configuration information through the RU. In one design, the first configuration information is sent through the RRC layer of the network device. In the O-RAN system, the 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.

[0257] The specific implementation of step 410 can be that the DU corresponding to the network device sends the reference signals corresponding to the Q channel measurement resources and the N interference measurement resources through the RU. In the O-RAN system, the specific implementation of step 410 can be that the O-DU corresponding to the network device sends the reference signals corresponding to the Q channel measurement resources and the N interference measurement resources through the O-RU.

[0258] The specific implementation of step 430 can be that the DU corresponding to the network device receives the measurement result through the RU. In one design, the measurement result can be received through the physical layer of the network device. In the O-RAN system, the specific implementation of step 430 can be that the O-DU corresponding to the network device receives the measurement result through the O-RU.
