Description

Technical Field

[0001] This application relates to the field of communications, and in particular to interference reporting methods, communication devices, storage media, and program products. Background Technology

[0002] In a wireless communication system, network devices can send configuration information to terminals via radio resource control (RRC) signaling to configure channel measurement resources and related parameters for reporting measurement results. Accordingly, the terminal measures the channel measurement resources based on the configuration information and reports channel status information (CSI). The network device formulates a scheduling strategy based on the CSI, and then the network device and the terminal transmit data based on the scheduling strategy.

[0003] However, the transmission between network devices and terminals may be affected by interference signals. These interference signals may 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 CSI, it may affect the transmission performance. Summary of the Invention

[0004] This application provides interference reporting methods, communication devices, storage media, and program products, with the aim of reducing interference and improving transmission performance.

[0005] Firstly, this application provides an interference reporting method, which can be executed by a first communication device. This first communication device can be a terminal, a communication module within the terminal, or a circuit or chip within the terminal responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip). This application does not limit the specific device to this method. The following example illustrates the method being executed by a terminal.

[0006] For example, the method includes: measuring Q channel measurement resources and N interference measurement resources; sending measurement results, which are used to indicate interference information corresponding to L of the Q channel measurement resources, wherein the interference information corresponding to the L channel measurement resources includes information on the interference measurement resources among the N interference measurement resources that cause interference to the L channel measurement resources, where Q, L, and N are positive integers, and Q is greater than or equal to L.

[0007] In the above technical solution, the terminal can report the interference information corresponding to L of the Q channel measurement resources, so that the network device can determine the interference status of the L channel measurement resources due to the interference measurement resources, thereby optimizing the scheduling strategy, reducing interference, and improving transmission performance.

[0008] Optionally, the measurement results may also include information on P channel measurement resources out of the Q channel measurement resources, where P is a positive integer and P is less than or equal to Q. In other words, the terminal may also report information on some or all of the Q channel measurement resources so that network devices can optimize scheduling strategies based on the channel measurement resource information, thereby improving transmission performance.

[0009] Secondly, this application provides an interference reporting method, which can be executed by a second communication device. This second communication device can be a network device, a component configured within the network device (such as a circuit, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the network device; this application does not limit its scope in this regard. The following example illustrates this method executed by a network device.

[0010] For example, the method includes: sending reference signals corresponding to Q channel measurement resources and N interference measurement resources; receiving measurement results, which are used to indicate interference information corresponding to L channel measurement resources among the Q channel measurement resources, wherein the interference information corresponding to the L channel measurement resources includes information on interference measurement resources among the N interference measurement resources that cause interference to the L channel measurement resources, where Q, L, and N are positive integers, and Q is greater than or equal to L.

[0011] In the above technical solution, the network device can obtain the interference information corresponding to L of the Q channel measurement resources, so that the network device can determine the interference status of the L channel measurement resources due to the interference measurement resources, thereby optimizing the scheduling strategy, reducing interference, and improving transmission performance.

[0012] In conjunction with the first and second aspects, in some possible implementations, the L channel measurement resources mentioned above include a first channel measurement resource, and the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold; and / or, the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource less than or equal to a second threshold.

[0013] Wherein, the aforementioned first channel measurement resource is any one of the aforementioned L channel measurement resources. In this application, "greater than or equal to" and "greater than" are interchangeable, and similarly, "less than or equal to" and "less than" are also interchangeable. For example, the interference information corresponding to the aforementioned first channel measurement resource, which includes information on interference measurement resources among the aforementioned N interference measurement resources whose interference to the first channel measurement resource is greater than or equal to a first threshold, can be replaced with: the interference information corresponding to the aforementioned first channel measurement resource includes information on interference measurement resources among the aforementioned N interference measurement resources whose interference to the first channel measurement resource is greater than the first threshold. As another example, the interference information corresponding to the first channel measurement resource, which includes information on interference measurement resources among the aforementioned N interference measurement resources whose interference to the first channel measurement resource is less than or equal to a second threshold, can be replaced with: the interference measurement resources among the aforementioned N interference measurement resources whose interference to the first channel measurement resource is less than the second threshold.

[0014] Furthermore, the information on the interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold can be the information on n interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold, where n is a positive integer and n is less than or equal to N. That is, the information on the interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold can be the information on one or more interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold.

[0015] For any of the L channel measurement resources mentioned above, the terminal can report information on the interference measurement resources that cause interference greater than or equal to the first threshold, or it can report information on the interference measurement resources that cause interference less than or equal to the second threshold. This allows the network device to obtain information on the interference status of each of the L channel measurement resources, thereby optimizing the scheduling strategy, reducing interference, and ultimately improving transmission performance.

[0016] In conjunction with the first and second aspects, in some possible implementations, each of the L channel measurement resources satisfies one or more of the following: at least one of the N interference measurement resources causes interference to each of the channel measurement resources that is greater than or equal to a first threshold; at least one of the N interference measurement resources causes interference to each of the channel measurement resources that is less than or equal to a second threshold; or, the signal quality of each of the channel measurement resources is greater than or equal to a third threshold.

[0017] The above scheme provides a method for selecting the L channel measurement resources so that the terminal can determine L of the Q channel measurement resources and then report the interference information corresponding to the L channel measurement resources.

[0018] In conjunction with the first and second aspects, in some possible implementations, the interference information corresponding to the L channel measurement resources includes: L first information and / or L second information; wherein each of the L first information corresponds to one of the L channel measurement resources, and each first information is used to indicate information about an interfering measurement resource whose interference to the corresponding channel measurement resource is 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 second information is used to indicate information about an interfering measurement resource whose interference to the corresponding channel measurement resource is less than or equal to a second threshold.

[0019] That is, the above measurement results may include L first information and / or L second information, providing the reporting content that may be included in the measurement results. For example, the terminal may report L first information and / or L second information to indicate the interference information corresponding to each of the L channel measurement resources, thereby facilitating the network device to obtain the interference status of each of the L channel measurement resources by the interference measurement resources, thereby optimizing the scheduling strategy, reducing interference, and improving transmission performance.

[0020] In conjunction with the first and second aspects, in some possible implementations, a first piece of information is a first bitmap, where each bit in the first bitmap corresponds to an 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; or, a first piece of information is an index of the N interference measurement resources mentioned above that causes interference to the channel measurement resource corresponding to the first information that is greater than or equal to the first threshold.

[0021] That is, the aforementioned L pieces of first information can be L first bitmaps, or L sets of indexes for interference measurement resources, providing multiple possible forms of first information, which is beneficial to improving the flexibility of the terminal in reporting interference information. Specifically, the index of each set of interference measurement resources in the aforementioned L sets can include the index of one or more of the aforementioned N interference measurement resources.

[0022] In combination with the first and second aspects, in some possible implementations, a second piece of information is a second bitmap, where each bit in the second bitmap corresponds to an 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; or, a second piece of information is an index of the N interference measurement resources mentioned above that causes interference less than or equal to the second threshold to the channel measurement resource corresponding to the second information.

[0023] That is, the aforementioned L pieces of second information can be L second bitmaps, or L sets of indexes for interference measurement resources, providing multiple possible forms of second information, which is beneficial to improving the flexibility of the terminal in reporting interference information. Specifically, the index of each set of interference measurement resources in the aforementioned L sets can include the indexes of one or more of the aforementioned N interference measurement resources.

[0024] Optionally, the aforementioned L first pieces of information and / or the aforementioned L second pieces of information are used to determine the interference information corresponding to the aforementioned L channel measurement resources.

[0025] In other words, the network device can determine the interference information corresponding to the L channel measurement resources based on the aforementioned L first information and / or the aforementioned L second information. For example, the interference information corresponding to the i-th channel measurement resource among the L channel measurement resources can be indicated by the i-th first / second information among the aforementioned L first / second information; in other words, the network device can determine the interference information corresponding to the i-th channel measurement resource among the L channel measurement resources by using the i-th first / second information among the aforementioned L first / second information, where i is a positive integer and i is less than or equal to L.

[0026] In conjunction with the first and second aspects, in some possible implementations, the above measurement results may also include first indication information, which is used to indicate the above L channel measurement resources.

[0027] In other words, the terminal can indicate which L channel measurement resources have reported interference information, so that the network device can identify the L channel measurement resources that have reported the corresponding interference information.

[0028] In combination with the first and second aspects, in some possible implementations, the first indication information includes the indexes of the L channel measurement resources; or, the first indication information includes a third bit map, where each bit in the third bit map corresponds to a channel measurement resource, and each bit is used to indicate whether interference information for the corresponding channel measurement resource has been reported.

[0029] That is, the aforementioned first indication information can be a third bit map, or an index of L channel measurement resources, providing a variety of possible forms of the first indication, which is beneficial to improving the flexibility of the terminal in indicating the aforementioned L channel measurement resources.

[0030] Optionally, the aforementioned first indication information is used by the network device to determine the channel measurement resources that have reported interference information.

[0031] In other words, network devices can determine the L channel measurement resources that have reported the corresponding interference information based on the aforementioned first indication information.

[0032] In combination with the first aspect and the second aspect, in some possible implementations, the above measurement results include a first part (part 1) and a second part (part 2), wherein the first part includes the above-mentioned first indication information; and the second part includes the above-mentioned L pieces of first information and / or the above-mentioned L pieces of second information.

[0033] The above scheme reports the measurement results in two parts. The first part contains relatively coarse information, while the second part contains more detailed information. This helps network devices determine whether more detailed measurement results are needed based on the coarser information in the first part. This progressively refined approach improves feedback efficiency, enabling the system to respond more quickly to channel changes. Furthermore, it allows for flexible selection of whether to report detailed or coarse measurement results based on actual needs and channel variations, thereby optimizing the use of feedback resources.

[0034] Thirdly, this application provides a communication device, including modules for implementing the methods of the first aspect and any possible implementation thereof, or including modules for implementing the methods of the second aspect and any possible implementation thereof.

[0063] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0064] The technical solutions provided in this application can be applied to various communication systems, such as: wireless local area network (WLAN), wireless fidelity (Wi-Fi) systems, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, sidelink communication systems, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems, or new radio access technology (NR). Among these, 5G mobile communication systems can include non-standalone (NSA) and / or standalone (SA) networking.

[0065] The technical solution provided in this application can also be applied to future communication systems. This application does not limit it in this regard.

[0066] To facilitate understanding of the method provided in this application, the following points will be explained first.

[0067] First, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, "first information" and "second information" are only used to distinguish different information and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0068] Second, in the embodiments illustrated herein, the terms and abbreviations, such as Channel State Information (CSI), Synchronization Signal Block (SSB), or Transmission Configuration Indicator (TCI), are merely exemplary examples given for ease of description and should not constitute any limitation on this application. This application does not preclude the possibility of defining other terms that can achieve the same or similar functions in existing or future protocols.

[0069] Third, the “protocol” involved in the embodiments of this application may refer to standard protocols in the field of communication, such as LTE protocol, NR protocol and related protocols applied to future communication systems, and this application does not limit it.

[0070] Fourth, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, and c can mean: 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.

[0071] Fifth, in this application, "instruction" can include direct and indirect instructions, as well as explicit and implicit instructions. The information indicated by a certain piece of information is called the information to be instructed. In specific implementation, there are many ways to instruct the information to be instructed, such as, but not limited to, directly instructing the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly instruct the information to be instructed by instructing other information, where there is a relationship between the other information and the information to be instructed; or it can only instruct a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement of various information, thereby reducing the instruction overhead to some extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to instruct the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0072] Sixth, in this application, communication between different devices can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. "Sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to a terminal" can be understood as the destination of the information being the terminal, which can include direct sending via the air interface, or indirect sending via the air interface by other units or modules. "Receiving configuration information from a network device" can be understood as the source of the configuration information being the network device, which can include direct reception from the network device via the air interface, or indirect reception from the network device via the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0073] In other words, sending and receiving can occur between devices, such as between network devices and terminals; or they can occur within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0074] It is understandable that information may undergo necessary processing, such as encoding and modulation, before being sent from the source to the destination. Similarly, the destination, upon receiving information from the source, can also perform corresponding processing, such as decoding and demodulation, to interpret the valid information from the source. Similar expressions in this application can be understood in a similar way and will not be elaborated further.

[0075] Seventh, in this application, descriptions such as "when," "under the circumstances," "if," and "if" all refer to the fact that the device (e.g., a network device or terminal) will make corresponding processing under certain objective circumstances. They are not time limits, nor do they require the device (e.g., a network device or terminal) to make a judgment action when implementing it, nor do they imply any other limitations.

[0076] Eighth, the correspondences shown in the tables of this application can be configured or predefined. The values ​​of the information in each table are merely examples and can be configured to other values; this application is not limited to these. When configuring the correspondences between information and parameters, it is not necessarily required to configure all the correspondences shown in each table. For example, the correspondences shown in some rows of the tables in this application may not be configured. Furthermore, appropriate modifications and adjustments can be made based on the above tables, such as splitting, merging, etc. The names of the parameters shown in the headings of the above tables can also use other names that the communication device can understand, and the values ​​or representations of the parameters can also be other values ​​or representations that the communication device can understand. In the implementation of the above tables, other data structures can also be used, such as arrays, queues, containers, stacks, linear lists, pointers, linked lists, trees, graphs, structures, classes, heaps, hash tables, or hash tables, etc.

[0077] Ninth, in this application, "predefined" can also be understood as: definition, pre-defined, storage, pre-storage, pre-negotiation, pre-configuration, solidification, or pre-firing.

[0078] The following will describe in detail the communication systems and scenarios to which the method provided in this application is applicable, with reference to the accompanying drawings.

[0079] Figure 1 This is a schematic diagram of the architecture of a communication system applicable to the method provided in this application. Figure 1 A schematic diagram of a possible, non-limiting system architecture is shown.

[0080] like Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (e.g., ...). Figure 1 110a and 110b (collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image), and each device may also include different functional units. Terminal 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or via wired connection. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0081] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4th generation (4G) mobile communication system, a 5G mobile communication system, or a future communication system. RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a Wi-Fi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0082] RAN node 110, sometimes also referred to as network equipment, access network equipment, RAN entity, or access node, is part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in the communication system 1000 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative, for example... Figure 1 Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices, for example... Figure 1 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0083] In one possible scenario, a 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. A RAN node can also be a macro base station (such as...) Figure 1 110a), micro base stations or indoor stations (such as Figure 1In CRAN scenarios, RAN nodes can be 110b, relay nodes, donor nodes, or wireless controllers. Optionally, RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU).

[0084] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing a portion of the base station's functions. For example, a RAN node can be a control unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0085] In this application, the access network equipment may typically include a communication module, circuit, or chip that performs the corresponding communication function. The access network equipment may also be configured with program instructions for performing the corresponding communication function, as well as corresponding program instructions.

[0086] A terminal can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal equipment, wireless communication equipment, user agent, or user device. A terminal typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The terminal may also be configured with program instructions for performing these communication functions.

[0087] Terminals can be devices or modules that access the aforementioned communication systems and possess corresponding communication functions. For example, a terminal can be a device that provides voice / data connectivity to a user, such as a handheld device or in-vehicle device with wireless connectivity. Currently, some examples of terminals include: mobile phones, tablets, computers with wireless transceiver capabilities (such as laptops and PDAs), mobile internet devices (MIDs), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving vehicles, drones, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). The following are examples of mobile communication devices: personal assistant (PDA), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, vehicles with wireless communication capabilities, communication modules, terminals in 5G networks, or terminals in future public land mobile networks (PLMNs).

[0088] Furthermore, a terminal can also be a terminal in an Internet of Things (IoT) system. IoT is an important component of future information technology development. Its main technical characteristic is connecting objects to networks via communication technologies, thereby realizing an intelligent network that enables human-machine interaction and machine-to-machine interaction. IoT technology can achieve massive connectivity, deep coverage, and low terminal power consumption through technologies such as narrowband (NB).

[0089] In addition, the terminal may also include sensors such as smart printers, train detectors, and gas stations. Its main functions include collecting data (for some terminals), receiving control information and downlink data from network devices, and sending electromagnetic waves to transmit uplink data to network devices.

[0090] In this embodiment of the application, the network device may be, for example, Figure 1 The RAN node 110 shown can be, for example, a terminal. Figure 1 The terminal 120 shown in this application does not specifically limit the type of network device and terminal.

[0091] In addition, the terminal and network device can be a hardware device, or a software function running on dedicated hardware, or a software function running on general-purpose hardware, such as a virtualization function instantiated on a platform (e.g., a cloud platform), or an entity that includes dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal and network device.

[0092] Figure 2 This is another schematic diagram of the architecture of a communication system applicable to the methods provided in this application. Figure 2 The communication system shown can be regarded as Figure 1 The communication system shown is simplified.

[0093] like Figure 2 As shown in a), the communication system includes one or more network devices (one network device is shown as an example in the figure) and one or more terminals (two terminals are shown as an example in the figure). It can be seen that a network device can transmit data or control signaling to one or more terminals.

[0094] like Figure 2 As shown in b), the communication system includes one or more network devices (three network devices are shown as an example in the figure) and one or more terminals (one terminal is shown as an example in the figure). It can be seen that multiple network devices can transmit data or control signaling to one terminal.

[0095] Figure 2 a) and Figure 2 In the communication system shown in b), the terminal can be mobile or fixed. The network device can be a micro base station, a TRP, or other types of network device; this application embodiment does not limit this. The network device can provide communication coverage for a specific geographical area and can communicate wirelessly with terminals located within that coverage area (cell).

[0096] Optionally, the communication system shown may include more network devices, and each network device may include other numbers of terminals within its coverage area; this application embodiment does not limit this.

[0097] Understandably, Figure 1 and Figure 2 The system architecture described is intended to more clearly illustrate the technical solutions of the embodiments of this application and does not constitute a limitation on the technical solutions provided in the embodiments of this application.

[0098] Figure 3 This is a schematic diagram of a scenario applicable to the method provided in this application.

[0099] like Figure 3 As shown, multiple network devices can send signals to multiple terminals, such as network device 1 sending a signal to terminal 1 and network device 2 sending a signal to terminal 2. Transmission between network devices and terminals may be affected by interference signals. These interference signals may be other signals sent by the same network device, such as signals sent by the same network device to other terminals; or they may be signals sent by other network devices. Interference from signals originating from the same network device can be called intra-cell interference, while interference from signals originating from different network devices can be called inter-cell interference.

[0100] An example, such as Figure 3 As shown, for a certain terminal, such as terminal 1, when terminal 1 receives a signal from network device 1, it may be interfered with by a signal from network device 2. This interference can be called inter-cell interference. Network device 1 and network device 2 can be in the same cell or different cells; this application does not limit this.

[0101] Another example, such as Figure 3 As shown, for a certain terminal, such as terminal 1, when terminal 1 receives a signal from network device 1, it may be interfered with by the signal sent by network device 1 to terminal 2. This interference can be called intra-cell interference.

[0102] Currently, intra-cell interference can be reduced through joint precoding. More specifically, when a network device needs to send signals to multiple terminals, the device performs joint precoding on the signals from these terminals based on their CSI (Combined Signal Indicator). Joint precoding ensures that the signal strength of a terminal's own signal is greater than the signal strength of signals belonging to other terminals.

[0103] Similarly, inter-cell interference can also be addressed using joint precoding. More specifically, when multiple network devices need to send signals to multiple terminals, the devices work together to perform joint precoding, thereby reducing interference between different cells and ensuring that the signal strength of the signal received by a terminal is greater than the signal strength of signals from other terminals (i.e., signals from other network devices).

[0104] Even with joint precoding, interference may still occur, affecting transmission performance. For example, in certain scenarios where network devices cannot achieve ideal coordination, inter-cell interference may still exist, thus impacting transmission performance.

[0105] To address this, this application provides an interference reporting method. A terminal can report interference information corresponding to L of the Q measured channel measurement resources, enabling network devices to determine the interference status of these L channel measurement resources. For example, the interference measurement resources can be interference measurement resources of a supplementary cell. In this way, network devices can determine the interference status of the serving cell's channel measurement resources 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.

[0106] To facilitate understanding of the interference reporting method provided in this application, the terminology used in this application will be explained in detail below.

[0107] 1. Beam: This can be understood as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL hypothesis, QCL indication, transmission configuration indicator (TCI) state, spatial relation, spatial basis, or discrete Fourier transform (DFT) basis, etc. Therefore, in this application, the concepts of beam, spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL hypothesis, QCL indication, TCI state (including uplink TCI state or downlink TCI state), spatial relation, spatial basis, or DFT basis are equivalent and can be substituted for each other.

[0108] The beam used to transmit signals can be called the transmission beam (Tx beam), or it can be referred to as a spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, spatial domain transmission setting, or spatial transmission setting. The downlink transmission beam can be indicated by the downlink TCI-state.

[0109] The beam used to receive signals can be called a reception beam (Rx beam), or it can be called a spatial domain reception filter, spatial reception filter, spatial domain reception parameter, spatial reception parameter, spatial domain reception setting, or spatial reception setting, etc.

[0110] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.

[0111] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beams. The technology used to form the beam can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc. The beam can refer to an analog beam, a digital beam, or a hybrid of both, i.e., a combined analog and digital beam generated by jointly using analog beam weights and digital beam weights.

[0112] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal provides feedback on the quality of the measured resources, allowing the network device to determine the quality of the corresponding beam. During data transmission, beam information can also be indicated through its corresponding resources. For instance, network devices can use the TCI field in downlink control information (DCI) to indicate the terminal's downlink beam information.

[0113] Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and detection signals, etc. One or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0114] In the embodiments of this application, unless otherwise specified, a beam refers to the transmit beam of a network device. In beam measurement, each beam of a network device corresponds to a resource, and therefore the beam corresponding to that resource can be uniquely identified by the resource index.

[0115] 2. Resources: In beam measurement, beams and resources can correspond, meaning there is a relationship between them (network devices use a beam to transmit their corresponding resources), and a terminal measuring the quality of a resource can be considered as measuring the quality of the beam. Resources can be uplink signal resources or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization signal block (SSB) resources.

[0116] Resources are configured via RRC messages. In terms of configuration structure, a resource is an information element (IE), including relevant parameters of its corresponding uplink / downlink reference signal, such as the type of uplink / downlink reference signal, the resource granularity carrying the uplink / downlink reference signal, the transmission time and period of the uplink / downlink reference signal, and the number of ports used to transmit the uplink / downlink reference signal. Each uplink / downlink reference signal resource has a unique index to identify it. It is understood that the index of the reference signal resource can also be called the identifier of the reference signal resource, and this application embodiment does not impose any limitation on this.

[0117] It should be understood that the resources listed above are merely illustrative examples and should not constitute any limitation on this application. This application does not preclude the possibility of defining other reference signals in future agreements to achieve the same or similar functions.

[0118] 3. Beam management: mainly divided into downlink beam management and uplink beam management.

[0119] 1) Downlink Beam Management

[0120] Downlink beam management mainly includes the following steps:

[0121] S1. The network device sends measurement configuration information to the terminal device. The network device sends measurement configuration information to the terminal via RRC messages, which mainly includes two parts: resource configuration information and reporting configuration information. Resource configuration information is related to measurement resources and is configured in the protocol using a three-level structure (resource configuration (resourceConfig) - resource set (resource) - resource (resource)). 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, it includes other parameters such as the resource period and the signal type corresponding to the resource. Reporting configuration information refers to information related to the reporting of measurement results, and is configured in the protocol through reporting configuration (ReportConfig). The network device can configure one or more reporting configurations for the terminal. Each reporting configuration includes reporting metrics, reporting time and period, reporting format, and other reporting-related information. Furthermore, the reporting configuration also includes an index of the resource configuration, used to indicate which measurement configuration was used to measure the reported results. The following are the specific formats for resource configuration and reporting configurations in the R15 protocol, to facilitate further understanding of the R15 measurement architecture. It should be understood that the formats shown below are only partial; more detailed configurations can be found in R15. Table 1 provides an example of resource configuration, and Table 2 provides an example of reporting configuration.

[0122] Table 1

[0123]

[0124] Table 2

[0125]

[0126] S2. The network device sends downlink signals on the resource granules corresponding to the resources configured in the resource configuration information, so that the terminal can determine the quality of each resource (or the quality of the downlink signal, or the quality of the beam corresponding to the resource) by measuring the downlink signals.

[0127] S3. The terminal measures the downlink signal according to the measurement configuration information.

[0128] S4. The terminal sends a beam measurement report to the network device. The beam measurement report may include the index of one or more resources, the quality of the resources, etc. Table 3 shows the reporting format used for beam measurements in the R15 protocol. The CSI-RS index (CRI) field and the SSB resource index (SSBRI) field indicate the resource index to be reported. Only CRI or SSBRI can be reported, or both can be reported. and This refers to the lengths of the CRI and SSBRI fields. RSRP represents the quality of the resource. RSRP reporting uses a differential reporting criterion, meaning the RSRP of the best resource (the RSRP field in Table 3) is reported using 7 bits of quantization, while other RSRP fields (differential RSRP in Table 3) are reported using 4 bits of quantization.

[0129] Table 3

[0130]

[0131] The above information can be carried on the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0132] 2) Uplink Beam Management

[0133] Uplink beam management mainly includes the following steps:

[0134] S1. The network device sends SRS configuration information to the terminal. The network device can configure one or more SRS resource sets for uplink beam management for the terminal. Each SRS resource set includes one or more SRS resources. Each SRS resource is associated with a beam. Each SRS resource includes an SRS signal; uplink beam measurement can be performed by measuring the SRS signals corresponding to these SRS resources. The specific format of 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 is only partial; more detailed configurations can be found in R15.

[0135] Table 4

[0136]

[0137] S2. The terminal transmits the corresponding SRS signal using the uplink transmit beam associated with each SRS resource according to the configuration of each SRS resource.

[0138] S3. The network device measures the quality of each SRS resource by measuring the various SRS signals sent by the measurement terminal.

[0139] As can be seen from the beam management process, network devices and terminals can communicate using specific beams, and the specific beam used is determined through beam measurement. For example, network devices can transmit downlink signals through various beams, with each beam corresponding to one downlink signal. The terminal determines the beam with better quality based on the measurement of the downlink signals.

[0140] The interference reporting method provided in this application will be described in detail below with reference to the accompanying drawings. The method is described using the interaction between a network device and a terminal as an example, and should not be construed as limiting this application in any way. The network device can also be replaced by components configured in the network device (such as circuits, chips, chip systems, processors, etc.), or logic modules or software capable of implementing 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 in the terminal responsible for communication functions (such as a modem chip (also known as a baseband chip) or a SoC or SIP chip containing a modem core).

[0141] Figure 4 This is a schematic flowchart of the interference reporting method 400 provided in the embodiments of this application. The various steps in method 400 are described in detail below.

[0142] 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 N interference measurement resources. Each measurement resource (channel measurement resource or interference measurement resource) corresponds to one reference signal.

[0143] In this context, channel measurement resources can be understood as resources used for channel measurement, and interference measurement resources can be understood as resources used for interference measurement (IM). Q and N are positive integers. For example, Q=1, N=1, meaning the network device sends a reference signal corresponding to one channel measurement resource and a reference signal corresponding to one interference measurement resource. In this application, measurement resources (channel measurement resources or interference measurement resources) can refer to a configuration parameter in the RRC configuration, which includes a parameter set or configuration unit corresponding to the reference signal used for measurement. For example, a measurement resource can refer to a parameter set or configuration unit corresponding to a reference signal used for measurement.

[0144] Optionally, the channel measurement resources mentioned above can be non-zero power CSI-RS resources or SSB resources. The interference measurement resources mentioned above can be non-zero power CSI-RS resources, zero power CSI-RS resources, CSI-IM resources, or SSB resources. This application does not limit the specific types of channel measurement resources and interference measurement resources.

[0145] In this application, the aforementioned N interference measurement resources can be interference measurement resources of the serving cell (also referred to as the local cell) or interference measurement resources of supplementary cells (also referred to as neighboring cells). Specifically, when the aforementioned N interference measurement resources are interference measurement resources of supplementary cells, these N interference measurement resources can be interference measurement resources of one supplementary cell or interference measurement resources of multiple supplementary cells; this application does not impose any limitation on this.

[0146] The serving cell can be understood as a cell configured by the network device for data transmission on the terminal. The network device configures all parameters of the serving cell to the terminal, and the terminal can independently transmit data through the serving cell. A supplementary cell can be understood as a cell configured by the network device for the terminal other than the serving cell. Supplementary cells can also be used for data transmission to some extent. The network device may not configure all parameters of the supplementary cell to the terminal, but instead configure the supplementary cell information as parameters of the serving cell. In other words, a supplementary cell depends on its associated serving cell to function. The network device can configure one or more supplementary cells for the terminal; that is, a serving cell can be associated with one or more supplementary cells, but only one supplementary cell is active at a time. The network device can use a serving cell and its associated active supplementary cell for joint transmission, also known as cross-cell multi-TRP transmission.

[0147] 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 N interference measurement resources. Correspondingly, the terminal receives the first configuration information.

[0148] The aforementioned Q channel measurement resources can be configured in the same resource set or in separate resource sets; this application does not impose any limitation on this. Similarly, the aforementioned N interference measurement resources can be configured in the same resource set or in separate resource sets. For example, when the aforementioned N interference measurement resources are interference measurement resources for multiple supplementary cells, the aforementioned N interference measurement resources can be configured in separate resource sets.

[0149] In this application, each channel measurement resource can correspond to a beam, or in other words, each channel measurement resource can be transmitted through a beam, or the reference signal corresponding to each channel measurement resource can be transmitted through a beam. Therefore, beams and channel measurement resources are equivalent and can be substituted for each other. Similarly, each interference measurement resource can correspond to a beam (which can be called an interference beam), or in other words, each interference measurement resource can be transmitted through an interference beam, or the reference signal corresponding to each interference measurement resource (which can be called an interference signal) can be transmitted through an interference beam. Therefore, interference beams and interference measurement resources are equivalent and can be substituted for each other.

[0150] Optionally, each of the above N interference measurement resources is associated with a physical cell index (PCI).

[0151] The aforementioned PCI can be either the PCI of the serving cell or the PCI of the supplementary cell. 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, then that 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, then that interference measurement resource is the interference measurement resource of the supplementary cell.

[0152] There are several possible designs for associating each interference measurement resource with a PCI:

[0153] One possible design is that the aforementioned N interference measurement resources are associated with the same PCI. In other words, the aforementioned N interference measurement resources can be used to measure the interference of the cell corresponding to the same PCI, which helps to measure the interference intensity of different interference signals in the same cell.

[0154] Another possible design is that the aforementioned N interference measurement resources are associated with N different PCIs. In other words, the aforementioned N interference measurement resources and N different PCIs are in one-to-one correspondence. That is to say, the aforementioned N interference measurement resources are used to measure the interference of N different cells. This helps to measure the interference intensity of interference signals of multiple cells at one time and helps to measure a wider range of interference situations.

[0155] Another possible design is that some of the aforementioned N interference measurement resources are associated with the same PCI, while other interference measurement resources can be associated with different PCIs. In this way, it is possible to measure the interference intensity of different interference signals in a single cell, or to measure the interference intensity of interference signals in multiple cells simultaneously.

[0156] In step 420, the terminal measures the Q channel measurement resources and N interference measurement resources.

[0157] In this context, "terminal measurement of channel measurement resources" can be understood as the terminal measuring the reference signal on the channel measurement resources, or in other words, the terminal measuring the beam corresponding to the channel measurement resources. Similarly, "terminal measurement of interference measurement resources" can be understood as the terminal measuring the interference signal on the interference measurement resources, or in other words, the terminal measuring the interference beam corresponding to the interference measurement resources. Accordingly, by measuring channel measurement resources, the terminal can obtain the quality of the channel measurement resources, that is, the quality of the beam corresponding to the channel measurement resources. Similarly, by measuring interference measurement resources, the terminal can obtain the quality of the interference measurement resources, that is, the quality of the interference beam corresponding to the interference measurement resources.

[0158] Optionally, in this application, the parameters used to measure beam quality include received signal strength indicator (RSSI), reference signal received power (RSRP), etc., but are not limited to these. For example, beam quality can also be measured by parameters such as reference signal receiving quality (RSRQ), signal-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), precoding matrix indicator (PMI), transmitted precoding matrix indicator (TPMI), rank indicator (RI), transmitted rank indicator (TRI), layer indicator (LI), and timing advance (TA).

[0159] The terminal measures the aforementioned Q channel measurement resources and N interference measurement resources. One possible implementation is that the terminal can measure the aforementioned Q channel measurement resources to obtain the quality of the aforementioned Q channel measurement resources, that is, to obtain the quality of the Q beams corresponding to the aforementioned Q channel measurement resources, and further determine the interference information corresponding to the aforementioned Q channel measurement resources.

[0160] The measurement results corresponding to the aforementioned Q channel measurement resources include the CSI corresponding to the aforementioned Q channel measurement resources. The CSI may include, for example, one or more of the following: Channel Quality Indicator (CQI), PMI, RI, RSRP, or SINR, etc. The CSI can be broadband-level CSI or subband-level CSI. The PMI can be type I or type II PMI. This application does not limit this.

[0161] It is understandable that the terminal can also measure a larger number of channel measurement resources (e.g., M, where M is greater than Q), and determine Q channel measurement resources from the M channel measurement resources. These Q channel measurement resources are the Q channels with better quality among the M channel measurement resources.

[0162] After determining the quality of the aforementioned Q channel measurement resources, the terminal can further determine the interference information corresponding to the aforementioned Q channel measurement resources. Taking any one of the aforementioned Q channel measurement resources (denoted as the second channel measurement resource) as an example, and not a limitation, for the second channel measurement resource, the terminal can determine the interference information of the aforementioned N interference measurement resources on the second channel measurement resource by measuring the aforementioned N interference measurement resources.

[0163] In one possible design, the interference information of the aforementioned N interference measurement resources on the second channel measurement resource refers to the information of the interference measurement resources among the aforementioned N interference measurement resources whose interference to the second channel measurement resource is greater than or equal to a first threshold. Wherein, any interference measurement resource (such as the first interference measurement resource) causing interference to the second channel measurement resource greater than or equal to the first threshold can mean, for example, that the signal quality of the first interference measurement resource is greater than or equal to a first preset threshold, or that the difference between the signal quality of the second channel measurement resource and the signal quality of the first interference measurement resource (e.g., 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 that 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.

[0164] Wherein, the signal quality of the first interference measurement resource is greater than or equal to a first preset threshold, which can be understood as the signal quality of the first interference measurement resource received by the terminal using the receiving beam of the second channel measurement resource being 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 is less than or equal to a second preset threshold, which can be understood as 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 using the receiving beam of the second channel measurement resource being less than or equal to the second preset threshold.

[0165] As previously mentioned, resources can be replaced by beams. For example, the beam corresponding to the aforementioned second channel measurement resource is the second beam. The terminal determines information about the interference beam whose interference to the second beam caused by any of the N interference beams corresponding to the aforementioned N interference measurement resources (denoted as the first interference beam) is greater than or equal to a first threshold. Wherein, the interference caused by the first interference beam to the second beam being greater than or equal to the first threshold can mean, for example, that the signal quality of the first interference beam is greater than or equal to a first preset threshold, or that the difference between the signal quality of the second beam and the signal quality of the first interference beam (e.g., 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 that 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.

[0166] The statement that the signal quality of the first interfering beam is greater than or equal to a first preset threshold can be understood as meaning that the signal quality of the first interfering beam received by the terminal using the receiving beam of the second beam is greater than or equal to the first preset threshold. Similarly, the statement that the difference between the signal quality of the second beam and the signal quality of the first interfering beam is less than or equal to a second preset threshold can be understood as meaning 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 interfering beam received by the receiving beam of the second beam is less than or equal to the second preset threshold.

[0167] In another possible design, the interference information of the aforementioned N interference measurement resources on the second channel measurement resource refers to the information of the interference measurement resources among the aforementioned N interference measurement resources whose interference to the second channel measurement resource is less than or equal to a second threshold. Specifically, the interference to the second channel measurement resource caused by any of the aforementioned N interference measurement resources (denoted as the first interference measurement resource) is less than or equal to the second threshold. For example, this could mean that the signal quality of the first interference measurement resource is less than or equal to a fourth preset threshold; or that the difference between the signal quality of the second channel measurement resource and the signal quality of the first interference measurement resource (e.g., the signal quality of the second channel measurement resource minus the signal quality of the first interference measurement resource) is greater than or equal to a fifth preset threshold; or that the SINR / CQI of the second channel measurement resource under the interference of the first interference measurement resource is greater than or equal to a sixth preset threshold.

[0168] Wherein, the signal quality of the first interference measurement resource is less than or equal to a fourth preset threshold, which can be understood as the signal quality of the first interference measurement resource received by the terminal using the receiving beam of the second channel measurement resource being 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 is greater than or equal to a fifth preset threshold, which can be understood as 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 using the receiving beam of the second channel measurement resource being greater than or equal to the fifth preset threshold.

[0169] As previously mentioned, resources can be replaced by beams. For example, the beam corresponding to the aforementioned second channel measurement resource is the second beam. The terminal determines information about the interference beam whose interference to the second beam caused by any of the N interference beams (the first interference beam) corresponding to the aforementioned N interference measurement resources is less than or equal to a second threshold. Wherein, the interference caused by the first interference beam to the second beam being less than or equal to the second threshold can, for example, mean that the signal quality of the first interference beam is less than or equal to a fourth preset threshold, or that the difference between the signal quality of the second beam and the signal quality of the first interference beam (e.g., the signal quality of the second beam minus the signal quality of the interference beam) is greater than or equal to a fifth preset threshold, or that the SINR / CQI of the second beam under the interference of the first interference beam is greater than or equal to a sixth preset threshold.

[0170] Specifically, the signal quality of the first interfering beam is less than or equal to a fourth preset threshold, which can be understood as the signal quality of the first interfering beam received by the terminal using the receiving beam of the second beam being less than or equal to the fourth preset threshold. The difference between the signal quality of the second beam and the signal quality of the first interfering beam is greater than or equal to a fifth preset threshold, which can be understood as 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 interfering beam received by the receiving beam of the second beam being greater than or equal to the fifth preset threshold.

[0171] It should be understood that the aforementioned first to sixth preset thresholds, as well as the aforementioned first and second thresholds, can all be predefined or indicated by the network device, and this application does not limit them in this regard. Furthermore, the aforementioned first to sixth preset thresholds, as well as the aforementioned first and second thresholds, can have the same value, partially the same value, or all different values, and this application does not limit their specific values.

[0172] In step 430, the terminal sends measurement results, which indicate the interference information corresponding to L of the Q channel measurement resources. Correspondingly, the network device receives the measurement results.

[0173] The interference information corresponding to the L channel measurement resources includes the information of the interference measurement resources that cause interference to the L channel measurement resources from the N interference measurement resources, where L is a positive integer and Q is greater than or equal to L.

[0174] The interference information corresponding to the L channel measurement resources mentioned above includes the interference information corresponding to each of the L channel measurement resources. In other words, each of the L channel measurement resources corresponds to one interference information. Taking any one of the L channel measurement resources (denoted as the first channel measurement resource) as an example, the interference information corresponding to the first channel measurement resource can be the information of the interfering measurement resources that cause interference to the first channel measurement resource among the N interfering measurement resources mentioned above.

[0175] Optionally, the terminal determines the L channel measurement resources from the Q channel measurement resources. One possible implementation is that each of the L channel measurement resources satisfies one or more of the following: at least one of the N interference measurement resources causes interference to each of the channel measurement resources that is greater than or equal to a first threshold; at least one of the N interference measurement resources causes interference to each of the channel measurement resources that is less than or equal to a second threshold; or, the signal quality of each of the channel measurement resources is greater than or equal to a third threshold.

[0176] Taking any one of the L channel measurement resources (denoted as the first channel measurement resource) as an example, the first channel measurement resource satisfies one or more of the following: At least one of the N interference measurement resources causes interference to the first channel measurement resource that is greater than or equal to a first threshold (which can be considered as strong interference to the first channel measurement resource); at least one of the N interference measurement resources causes interference to the first channel measurement resource that is less than or equal to a second threshold (which can be considered as weak interference to the first channel measurement resource); or, the 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.

[0177] One possible implementation is that, for any one of the Q channel measurement resources (denoted as the second channel measurement resource), the terminal determines the interference caused by each of the N interference measurement resources to the second channel measurement resource. If at least one of the N interference measurement resources causes interference to the second channel measurement resource that is greater than or equal to a first threshold, then the second channel measurement resource belongs to one of the L channel measurement resources. If none of the N interference measurement resources causes interference to the second channel measurement resource that is greater than or equal to the first threshold (or if all of the N interference measurement resources cause interference to the second channel measurement resource that is less than the first threshold), then the second channel measurement resource does not belong to the L channel measurement resources.

[0178] Another possible implementation is that, for any one of the Q channel measurement resources (denoted as the second channel measurement resource), the terminal determines the interference caused by each of the N interference measurement resources to the second channel measurement resource. If at least one of the N interference measurement resources causes interference to the second channel measurement resource that is less than or equal to a second threshold, then the second channel measurement resource belongs to one of the L channel measurement resources. If none of the N interference measurement resources causes interference to the second channel measurement resource that is less than or equal to the second threshold (or if all of the N interference measurement resources cause interference to the second channel measurement resource that is greater than the second threshold), then the second channel measurement resource does not belong to the L channel measurement resources.

[0179] Another possible implementation is that, for the aforementioned second channel measurement resource, if the signal quality of the second channel measurement resource is greater than or equal to the third threshold, then the second channel measurement resource belongs to one of the aforementioned L channel measurement resources; if the signal quality of the second channel measurement resource is less than the third threshold, then the second channel measurement resource does not belong to the aforementioned L channel measurement resources.

[0180] Another possible implementation is that, for the aforementioned second channel measurement resource, if the signal quality of the second channel measurement resource is greater than or equal to a third threshold, then the interference caused by each of the aforementioned N interference measurement resources to the aforementioned second channel measurement resource is further determined. If at least one of the aforementioned N interference measurement resources causes interference to the aforementioned second channel measurement resource greater than or equal to a first threshold, then the second channel measurement resource belongs to one of the aforementioned L channel measurement resources; if none of the aforementioned N interference measurement resources causes interference to the aforementioned second channel measurement resource greater than or equal to the first threshold, then the second channel measurement resource does not belong to the aforementioned L channel measurement resources. If the signal quality of the second channel measurement resource is less than the third threshold, then the second channel measurement resource does not belong to the aforementioned L channel measurement resources. These are not listed individually here.

[0181] Taking any one of the L channel measurement resources mentioned above (denoted as the first channel measurement resource) as an example, the interference information corresponding to the first channel measurement resource may be designed as follows: the interference information corresponding to the first channel measurement resource includes the information of the interference measurement resources among the N interference measurement resources mentioned above that cause interference to the first channel measurement resource that is greater than or equal to the first threshold.

[0182] Another possible design is that the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the above N interference measurement resources that cause interference to the first channel measurement resource less than or equal to the second threshold.

[0183] It is understood that the two possible designs described above can be used in combination or individually. When the two possible designs are used in combination, the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold, and information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource less than or equal to a second threshold.

[0184] In this application, "greater than or equal to" and "greater than" are interchangeable, and similarly, "less than or equal to" and "less than" are also interchangeable. For example, the interference information corresponding to the first channel measurement resource mentioned above, which includes information on the interference measurement resources among the N interference measurement resources whose interference to the first channel measurement resource is greater than or equal to a first threshold, can be replaced with: the interference information corresponding to the first channel measurement resource includes information on the interference measurement resources among the N interference measurement resources whose interference to the first channel measurement resource is greater than the first threshold. As another example, the interference information corresponding to the first channel measurement resource, which includes information on the interference measurement resources among the N interference measurement resources whose interference to the first channel measurement resource is less than or equal to a second threshold, can be replaced with: the interference measurement resources among the N interference measurement resources whose interference to the first channel measurement resource is less than the second threshold.

[0185] Furthermore, the information on the interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold can be the information on n interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold, where n is a positive integer and n is less than or equal to N. That is, the information on the interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold can be the information on one or more interference measurement resources among the aforementioned N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to the first threshold.

[0186] The information regarding the aforementioned interference measurement resource may include one or more of the following: the index of the interference measurement resource, or the interference intensity caused by the interference measurement resource to the first channel measurement resource. The interference intensity caused by the interference measurement resource to the first channel measurement resource may be, for example, the RSRP of the signal on the interference measurement resource; for instance, a larger RSRP indicates greater interference from the interference measurement resource to the first channel measurement resource. The interference intensity caused by the interference measurement resource to the first channel measurement resource may also be the CQI of the signal on the first channel measurement resource under the interference of the interference measurement resource; for instance, a larger CQI indicates less interference. The interference intensity caused by the interference measurement resource to the first channel measurement resource may also be the SINR of the signal on the first channel measurement resource under the interference of the interference measurement resource; for instance, a larger SINR indicates less interference.

[0187] The following section will provide a detailed description of the content included in the measurement results reported by the terminal.

[0188] The above measurement results may include one or more of the following: information of P channel measurement resources among the above Q channel measurement resources, first indication information, or interference information corresponding to the above L channel measurement resources.

[0189] Where P is a positive integer, P is less than or equal to Q, in other words, the terminal can also report information about some or all of the aforementioned Q channel measurement resources. The information about the aforementioned P channel measurement resources includes, for example, the index of the aforementioned P channel measurement resources and / or the quality of the aforementioned P channel measurement resources. The quality of the aforementioned P channel measurement resources can, for example, be the CSI of the aforementioned P channel measurement resources.

[0190] The aforementioned first indication information is used to indicate the aforementioned L channel measurement resources. That is, the terminal can indicate which L channel measurement resources have reported interference information, so that the network device can determine the L channel measurement resources that reported the corresponding interference information. In other words, the aforementioned first indication information can be used by the network device to determine the channel measurement resources that reported interference information. Specifically, the network device can determine the aforementioned L channel measurement resources that reported the corresponding interference information based on the aforementioned first indication information.

[0191] Optionally, the example above illustrates that information about P channel measurement resources out of 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 message. However, this should not constitute any limitation on this application. For example, information about P channel measurement resources out of 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 messages; that is, the above content can also be transmitted separately. One possible design is that the first indication information includes the index of the L channel measurement resources.

[0192] Another possible design is that the aforementioned first indication information includes a third bitmap, where each bit in the third bitmap corresponds to a channel measurement resource, and each bit is used to indicate whether interference information for the corresponding channel measurement resource has been reported. For example, a bit value of 1 indicates that the measurement result includes interference information for the channel measurement resource; a bit value of 0 indicates that the measurement result does not include interference information for the channel measurement resource. Alternatively, a bit value of 1 indicates that the measurement result does not include interference information for the channel measurement resource; a bit value of 0 indicates that the measurement result includes interference information for the channel measurement resource.

[0193] The interference information corresponding to the aforementioned L channel measurement resources may be designed in one way, including one or more of the following: L first information and L second information; wherein, each of the L first information corresponds to one of the aforementioned L channel measurement resources, and each first information is used to indicate information about interference measurement resources whose interference to the corresponding channel measurement resource is greater than or equal to a first threshold; each of the L second information corresponds to one of the aforementioned L channel measurement resources, and each second information is used to indicate information about interference measurement resources whose interference to the corresponding channel measurement resource is less than or equal to a second threshold.

[0194] That is, the above measurement results may include L first pieces of information and / or L second pieces of information.

[0195] As an example, the above measurement results include L first pieces of information, each first piece of information being used to indicate information about the N interference measurement resources among which the interference caused to the channel measurement resource corresponding to the first piece of information is greater than or equal to a first threshold.

[0196] In another example, the above measurement results include L pieces of second information, each piece of second information indicating the information of the N interference measurement resources that cause interference to the channel measurement resource corresponding to the first information that is less than or equal to a second threshold.

[0197] In another example, the above measurement results include L first pieces of information and L second pieces of information. Each piece of first information is used to indicate the information of the N interference measurement resources that cause interference to the channel measurement resource corresponding to the first information that is greater than or equal to a first threshold. Each piece of second information is used to indicate the information of the N interference measurement resources that cause interference to the channel measurement resource corresponding to the first information that is less than or equal to a second threshold.

[0198] Regarding the possible reporting format of the first information, one possible design is that each piece of first information is a first bitmap, where each bit in the first bitmap corresponds to an interference measurement resource. 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 aforementioned L pieces of first information corresponds to one first bitmap, and the aforementioned L pieces of first information include 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; a bit value of 0 indicates that the interference caused by the corresponding interference measurement resource to the channel measurement resource corresponding to the first information is less than the first threshold. As 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; 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.

[0199] Another possible design is that a first piece of information is an index of the N interference measurement resources mentioned above, where the interference caused to the channel measurement resource corresponding to the first piece of information is greater than or equal to a first threshold. That is, each of the L pieces of first information corresponds to a set of indexes of interference measurement resources, and the number of indexes in a set of interference measurement resource indexes can be one or more, and the L pieces of first information include L sets of indexes of interference measurement resources.

[0200] Regarding the reporting format of the second information, one possible design is that each piece of second information is a second bitmap, where each bit in the second bitmap corresponds to an interference measurement resource. Each bit is used to indicate whether the corresponding interference measurement resource causes interference to the channel measurement resource corresponding to the second information that is less than or equal to a second threshold. That is, each of the aforementioned L pieces of second information corresponds to one second bitmap, and the aforementioned L pieces of second information include L second bitmaps. For example, a bit value of 1 indicates that the corresponding interference measurement resource causes interference to the channel measurement resource corresponding to the second information that is less than or equal to the second threshold; a bit value of 0 indicates that the interference caused by the corresponding interference measurement resource to the channel measurement resource corresponding to the second information is greater than the second threshold. Alternatively, a bit value of 1 indicates that the corresponding interference measurement resource causes interference to the channel measurement resource corresponding to the second information that is greater than the second threshold; a bit value of 0 indicates that the corresponding interference measurement resource causes interference to the channel measurement resource corresponding to the second information that is less than or equal to the second threshold.

[0201] Another possible design is that a second piece of information is an index of the N interference measurement resources mentioned above, where the interference caused to the channel measurement resource corresponding to the second piece of information is less than or equal to a second threshold. That is, each of the L pieces of second information corresponds to a set of indexes of interference measurement resources, and the number of indices in a set of interference measurement resource indices can be one or more, and the L pieces of second information include L sets of indexes of interference measurement resources.

[0202] It is understood that when the above measurement results include L first pieces of information and L second pieces of information, each of the L first pieces of information can be a first bitmap, and each of the L second pieces of information can be a second bitmap; or, each of the L first pieces of information can be an index of a set of interference measurement resources, and each of the L second pieces of information can be an index of a set of interference measurement resources; or, each of the L first pieces of information can be a first bitmap, and each of the L second pieces of information can be an index of a set of interference measurement resources; or, each of the L first pieces of information can be an index of a set of interference measurement resources, and each of the L second pieces of information is a second bitmap. This application does not limit this; for example, some of the L first pieces of information may be in the form of a first bitmap, and the remaining first pieces of information may be in the form of an index of a set of interference measurement resources, which will not be listed here. Optionally, the L first pieces of information and / or the L second pieces of information are used to determine the interference information corresponding to the L channel measurement resources.

[0203] In other words, the network device can determine the interference information corresponding to the L channel measurement resources based on the aforementioned L first information and / or the aforementioned L second information. For example, the interference information corresponding to the i-th channel measurement resource among the L channel measurement resources can be indicated by the i-th first / second information among the aforementioned L first / second information; in other words, the network device can determine the interference information corresponding to the i-th channel measurement resource among the L channel measurement resources by using the i-th first / second information among the aforementioned L first / second information, where i is a positive integer and i is less than or equal to L.

[0204] Optionally, the above measurement results include a first part (part 1) and a second part (part 2), wherein the first part includes the aforementioned first indication information; and the second part includes the aforementioned L pieces of first information and / or the aforementioned L pieces of second information. Based on the first part, the network device can determine which L channel measurement resources the terminal reported the interference information corresponding to, and based on the second part, can further determine the interference information corresponding to those L channel measurement resources.

[0205] Optionally, the first part may also include information on P channel measurement resources out of the aforementioned Q channel measurement resources.

[0206] The above scheme reports the measurement results in two parts. The first part contains relatively coarse information, while the second part contains more detailed information. This helps network devices determine whether more detailed measurement results are needed based on the coarser information in the first part. This progressively refined approach improves feedback efficiency, enabling the system to respond more quickly to channel changes. Furthermore, it allows for flexible selection of whether to report detailed or coarse measurement results based on actual needs and channel variations, thereby optimizing the use of feedback resources.

Figure 4 In step 410, reference signals corresponding to Q channel measurement resources and N interference measurement resources are sent; the transceiver module 510 (specifically, a receiving module) can be used to receive measurement results, which are used to indicate the interference information corresponding to L channel measurement resources among the Q channel measurement resources. The interference information corresponding to the L channel measurement resources includes the information of the interference measurement resources among the N interference measurement resources that cause interference to the L channel measurement resources. Q, L, and N are positive integers, and Q is greater than or equal to L.

[0221] Optionally, the L channel measurement resources mentioned above include a first channel measurement resource, and the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource greater than or equal to a first threshold; and / or, the interference information corresponding to the first channel measurement resource includes: information on the interference measurement resources among the N interference measurement resources that cause interference to the first channel measurement resource less than or equal to a second threshold.

When the communication device 600 is a chip applied to a terminal or network device, the communication interface 620 can be an input / output circuit, a bus, a module, a pin, or other types of communication interface. The input circuit in the input / output circuit can be used for receiving, and the output interface can be used for sending. For example, when the communication device 600 is used to perform...

[0244] Figure 7 This is a schematic diagram of the communication device provided in the embodiments of this application communicating.

[0245] like Figure 7 As shown, terminal 10 logically includes multiple parts, such as processor 101, memory 102, and transceiver 103. Transceiver 103 includes transmitter 1031, receiver 1032, and antenna 1033. Network device 20 logically includes multiple parts, such as processor 201, memory 202, and transceiver 203. Transceiver 203 includes transmitter 2031, receiver 2032, and antenna 2033. Receiver 1032 can be used to receive information sent by network device 20 through antenna 1033, and transmitter 1031 can be used to send information to network device 20 through antenna 1033. Transmitter 2031 can be used to send information to terminal 10 through antenna 2033, and receiver 2032 can be used to receive information sent by terminal 10 through antenna 2033.

[0246] For example, terminal 10 can be used to implement Figure 4 In the method embodiment shown, the steps executed by the terminal include, for example, the processor 101 can be used to execute step 420, the transceiver 103 can be used to execute steps 410 and 430, and can also be used to execute step 405, and the network device 20 can be used to implement... Figure 4 The steps performed by the network device in the method embodiment shown are as follows: for example, transceiver 203 can be used to perform steps 410 and 430, and can also be used to perform step 405. A more detailed description can be found by referring directly to... Figure 4 The relevant descriptions in the method embodiments shown are not repeated here.

[0247] Figure 8 This is a schematic diagram of an O-RAN system provided in an embodiment of this application. The O-RAN system may also include... Figure 8 Other components besides those shown.

[0248] like Figure 8 As shown, the network device in this embodiment can also be called an access network device. The access network device (i.e., RAN, such as an eNB, gNB, or next-generation access network device) can communicate with the core network (CN) through a backhaul link, or it can communicate with the terminal through an air interface.

[0249] Specifically, the BBU in the access network equipment communicates with the core network equipment via a backhaul link; the RU in the access network equipment communicates with at least one terminal via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0250] The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0251] Figure 9 This is a schematic diagram of an access network device applicable to the interference reporting method provided in this application. For example... Figure 9 As shown, the access network equipment includes one or more CUs, one or more DUs, and one or more RUs. For clarity, Figure 9 Only one CU, DU, and RU are shown. The CU is used to connect to the core network and one or more DUs. Optionally, the CU may have some of the functions of the core network. The CU may include CU-CP and CU-UP.

[0252] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of the protocol layers below the PDCP layer (such as the Radio Link Control (RLC) layer, the Medium Access Control (MAC) layer, and / or the Physical (PHY) layer). Alternatively, the CU can be configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC and / or SDAP layers), and the DU can be configured to implement the functions of the protocol layers below the PDCP layer (such as the RLC, MAC, and / or PHY layers).

[0253] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0254] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF network element in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0255] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) element in a 5G system, are responsible for forwarding and receiving data in terminal devices.

[0256] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0257] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0258] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open-CU (open-CU, O-CU), DU can also be called an open-DU (open-DU, O-DU), CU-CP can also be called an open-CU-CP (open-CU-CP, O-CU-CP), CU-UP can also be called an open-CU-UP (open-CU-UP, O-CU-UP), and RU can also be called an open-RU (open-RU, O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0259] exist Figure 4 In the illustrated embodiment, step 405 can be specifically implemented as follows: 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, step 405 can be specifically implemented as follows: the O-DU corresponding to the network device sends the aforementioned first configuration information through the O-RU.

[0260] Step 410 can be implemented as follows: the DU corresponding to the network device sends reference signals corresponding to Q channel measurement resources and N interference measurement resources through the RU. In the O-RAN system, step 410 can be implemented as follows: the O-DU corresponding to the network device sends the reference signals corresponding to the aforementioned Q channel measurement resources and N interference measurement resources through the O-RU.

[0261] Step 430 can be implemented as follows: the DU corresponding to the network device receives the measurement results through the RU. In one design, the measurement results can be received through the physical layer of the network device. In the O-RAN system, step 430 can be implemented as follows: the O-DU corresponding to the network device receives the above measurement results through the O-RU.
