Interference Measurement Methods and Apparatus
[0001] This application claims priority to Chinese Patent Application No. 202510138680.1, filed on February 7, 2025, entitled "Interference Measurement Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of communications, and particularly to interference measurement methods and apparatus in the field of communications. Background Technology
[0003] In the field of communications, duplexing methods include frequency division duplex (FDD) and time division duplex (TDD). In TDD, because uplink and downlink transmissions cannot occur simultaneously between terminal devices and network devices within the same time domain unit (such as a time slot or orthogonal frequency division multiplexing (OFDM) symbol), transmission delays are relatively large. Therefore, subband full duplex (SBFD) has been proposed. SBFD can be understood as follows: based on TDD, some frequency domain resources (called subbands) within a certain time domain unit are configured as uplink resources, and other frequency domain resources are configured as downlink resources, allowing simultaneous uplink and downlink transmissions within that specific time domain unit.
[0004] In communication systems, regardless of whether TDD or SBFD is used, for terminal devices that are close together (e.g., less than a certain threshold), some terminal devices may perform uplink transmissions while others perform downlink transmissions within the same time domain unit. This results in cross-link interference (CLI) between these close terminal devices. To reduce CLI between terminal devices, network devices can implement interference avoidance based on CLI measurement results from the terminal devices. For example, within the same time domain unit, the network device can schedule close terminal devices to avoid simultaneous uplink and downlink transmissions.
[0005] However, network devices may be less effective at avoiding interference. Summary of the Invention
[0006] This application provides an interference measurement method and apparatus, which helps to improve the interference avoidance effect of network devices, thereby reducing CLI between terminal devices and improving communication performance.
[0007] In a first aspect, an interference measurement method is provided, the method comprising: receiving first information, the first information being used to configure first resources and second resources, the first resources being used to measure a first cross-link interference (CLI) on a first time domain unit, the second resources being used to measure a second CLI on a second time domain unit, the first time domain unit being a half-duplex time domain unit, and the second time domain unit being a full-duplex time domain unit; and sending second information, the second information being used to indicate the first CLI and the second CLI.
[0008] In one possible implementation, the method is performed by a first communication device. The first communication device can be understood as a terminal device. Furthermore, the first communication device can be the terminal device itself, or a component applied to the terminal device (e.g., a chip, chip system, circuit, software and / or hardware module, etc.).
[0009] The interference measurement method of this application involves a terminal device measuring a first CLI on a first resource and a second CLI on a second resource. The terminal device then reports both the first and second CLIs to the network device. Since the first CLI represents inter-cell interference, and the second CLI includes both inter-cell and intra-cell interference, the network device can determine the type of interference between UEs' CLIs by combining the first and second CLIs.
[0010] For example, when the first CLI and the second CLI are close, and the first CLI is larger (e.g., greater than a certain threshold), it indicates that the second CLI mainly consists of inter-cell interference, meaning that the UE-to-UE CLI experienced by the terminal device is mainly inter-cell interference. In this case, the network device can schedule terminal devices located in different cells that are close to each other to perform only uplink or downlink transmissions in the same time domain unit.
[0011] Alternatively, if the second CLI is much larger than the first CLI (e.g., the difference is greater than a certain threshold), and the first CLI is smaller (e.g., less than a certain threshold), it indicates that the second CLI mainly includes intra-cell interference, meaning that the UE-to-UE CLI experienced by the terminal device is mainly intra-cell interference. In this case, the network device can schedule nearby terminal devices in the same cell to perform only uplink or downlink transmission in the same time domain unit.
[0012] In this way, network devices can combine the determined types of CLI interference between UEs to more accurately schedule terminal devices and avoid interference more effectively, thereby helping to reduce CLI between UEs and improve the communication performance of terminal devices.
[0013] In some embodiments of the first aspect, the second information includes first sub-information and second sub-information, the first sub-information indicating a first CLI and the second sub-information indicating a second CLI; or, the second information indicating a first CLI and a first difference, the first difference being the difference between the second CLI and the first CLI; or, the second information indicating a second CLI and a second difference, the second difference being the difference between the first CLI and the second CLI.
[0014] The first sub-information and the second sub-information can be carried in the same or different CSI reports. The first difference and the second difference can be the same or different, and the first difference (or the second difference) can be the difference between the first CLI and the second CLI, or the difference between the second CLI and the first CLI.
[0015] Thus, when the second information includes both the first and second sub-information, the network device can directly determine the first CLI based on the first sub-information and directly determine the second CLI based on the second sub-information. Even if the network device fails to receive the second sub-information, it can still determine the first CLI based on the first sub-information; or, even if the network device fails to receive the first sub-information, it can still determine the second CLI based on the second sub-information.
[0016] When the second information indicates the first CLI and the first difference, since the first difference may be smaller than the value of the second CLI, the signaling overhead of the terminal device reporting the first difference may be smaller compared to the second CLI.
[0017] When the second information indicates the second CLI and the second difference, since the second difference may be smaller than the value of the first CLI, the signaling overhead of the terminal device reporting the second difference may be smaller compared to the first CLI.
[0018] In some embodiments of the first aspect, the first frequency domain resources on the second time domain unit are used for downlink transmission, and the second frequency domain resources on the second time domain unit are used for uplink transmission; and the second CLI includes at least one of a third CLI or a fourth CLI, wherein the third CLI is measured on some or all of the resources in the first frequency domain resources, and the fourth CLI is measured on some or all of the resources in the second frequency domain resources.
[0019] The first frequency domain resource can also be understood as the DL subband, and the second frequency domain resource can also be understood as the UL subband.
[0020] In this way, the third CLI can accurately reflect the inter-UE CLI on the DL subband; the fourth CLI can accurately reflect the inter-UE CLI on the UL subband. This helps network devices to perform interference avoidance more accurately, so that the inter-UE CLI of terminal devices performing downlink transmission on the DL subband is smaller, and / or, so that the inter-UE CLI of terminal devices performing uplink transmission on the UL subband is smaller.
[0021] In some embodiments of the first aspect, the method further includes: sending third information, the third information indicating a first switching time and / or a number of switching operations; the first switching time being the time required to switch between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource; the number of switching operations being the number of times switching between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource across a plurality of consecutive second time domain units; wherein the first frequency domain resource is a resource used for downlink transmission on a second time domain unit, and the second frequency domain resource is a resource used for uplink transmission on a second time domain unit.
[0022] The downlink transmission on the first frequency domain resource can include: receiving downlink signals from network devices (such as downlink data sent from network devices to terminal devices) on the first frequency domain resource, and / or performing CLI measurements on the first frequency domain resource. The switching can be understood as a switching of the downlink filtering bandwidth. Although the second frequency domain resource is used for uplink transmission, since the CLI on the second frequency domain resource is interference caused by downlink signal leakage onto the second frequency domain resource, performing CLI measurements on the second frequency domain resource is also considered downlink filtering.
[0023] In this way, the terminal device and network device can accurately determine the resources actually measured by the terminal device when performing CLI measurements based on the first handover time and / or the number of handovers.
[0024] Optionally, the first handover time can be one of multiple handover times. These multiple handover times can be predefined by the protocol or configured by the network device via signaling. Therefore, the first handover time reported by the terminal device can be one of these multiple handover times.
[0025] In some embodiments of the first aspect, the method further includes: receiving fourth information, the fourth information being used to indicate a first measurement resource, the first measurement resource being the measurement resource closest to a third resource, the first CLI and / or the second CLI being measured based on the first measurement resource, and the third resource being used to carry the second information.
[0026] The first measurement resource can be understood as the measurement resource in one or more time slots that is closest to the third resource among multiple time slots. The measurement resources in the multiple time slots can be resources configured by the first information. The measurement resources in the multiple time slots include the first resource and the second resource. The first resource and the second resource can be understood as two types of resources. Furthermore, the first measurement resource can include both the first resource and / or the second resource. When the first measurement resource includes the first resource, and the first CLI is measured based on the first resource, the terminal device can report the first CLI; and / or, when the first measurement resource includes the second resource, and the second CLI is measured based on the second resource, the terminal device can report the second CLI.
[0027] In this way, the first CLI and / or the second CLI can more accurately reflect the CLI between UEs on the current channel.
[0028] In some embodiments of the first aspect, the first CLI is the average of a plurality of first measurements obtained on the first measurement resource, the plurality of first measurements being obtained on a first time-domain unit in the first measurement resource; and / or, the second CLI is the average of a plurality of second measurements obtained on the first measurement resource, the plurality of second measurements being obtained on a second time-domain unit in the first measurement resource.
[0029] The first time-domain unit of the first measurement resource may include multiple REs, and the multiple first measurements may be obtained on some or all of the multiple REs. For example, one first measurement value may be measured on each of the multiple REs. The second time-domain unit of the first measurement resource may include multiple REs, and the multiple second measurements may be obtained on some or all of the multiple REs. For example, one second measurement value may be measured on each of the multiple REs.
[0030] In this way, the first CLI can accurately reflect the inter-UE CLI on the resource in the first time domain unit of the first measurement resource; the first CLI can also accurately reflect the inter-UE CLI on the resource in the second time domain unit of the first measurement resource. This helps network devices to accurately determine the interference type of the current inter-UE CLI.
[0031] Optionally, the first CLI is a linear average (or average value) of the total power measured on the first resource in the first measurement resource; and / or, the second CLI is a linear average (or average value) of the total power measured on the second resource in the first measurement resource.
[0032] In some embodiments of the first aspect, the first CLI includes a first reference signal received power (RSRP) and / or a first received signal strength indication (RSSI); the second CLI includes a second RSRP and / or a second RSSI.
[0033] In other words, CLI can be characterized by RSRP and / or RSSI. RSRP and RSSI can be understood as different interference indicators.
[0034] Secondly, another interference measurement method is provided, the method comprising: sending first information, the first information being used to configure first resources and second resources, the first resources being used to measure a first cross-link interference (CLI) on a first time domain unit, the second resources being used to measure a second CLI on a second time domain unit, the first time domain unit being a half-duplex time domain unit, and the second time domain unit being a full-duplex time domain unit; and receiving second information, the second information being used to indicate the first CLI and the second CLI.
[0035] In one possible implementation, the method is performed by a second communication device. The second communication device can be understood as a network device. The second communication device can be the network device itself, or a component applied to the network device (e.g., a chip, chip system, circuit, software and / or hardware module, etc.).
[0036] In some embodiments of the second aspect, the second information includes first sub-information and second sub-information, the first sub-information being used to indicate a first CLI and the second sub-information being used to indicate a second CLI; or, the second information being used to indicate a first CLI and a first difference, the first difference being the difference between the second CLI and the first CLI; or, the second information being used to indicate a second CLI and a second difference, the second difference being the difference between the first CLI and the second CLI.
[0037] In some embodiments of the second aspect, the first frequency domain resources on the second time domain unit are used for downlink transmission, and the second frequency domain resources on the second time domain unit are used for uplink transmission; and the second CLI includes at least one of a third CLI or a fourth CLI, wherein the third CLI is measured on some or all of the resources in the first frequency domain resources, and the fourth CLI is measured on some or all of the resources in the second frequency domain resources.
[0038] In some embodiments of the second aspect, the method further includes: receiving third information, the third information indicating a first switching time and / or a number of switching operations; the first switching time being the time required to switch between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource; the number of switching operations being the number of times switching between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource across a plurality of consecutive second time domain units; wherein the first frequency domain resource is a resource used for downlink transmission on a second time domain unit, and the second frequency domain resource is a resource used for uplink transmission on a second time domain unit.

[0041] Optionally, the first CLI is a linear average (or average value) of the total power measured on the first resource in the first measurement resource; and / or, the second CLI is a linear average (or average value) of the total power measured on the second resource in the first measurement resource.
[0042] In some embodiments of the second aspect, the first CLI includes a first reference signal received power (RSRP) and / or a first received signal strength indication (RSSI); the second CLI includes a second RSRP and / or a second RSSI.
[0043] Thirdly, an interference measurement method is provided, comprising: receiving seventh information, the seventh information being used to configure a fourth resource, the fourth resource being used for cross-link interference (CLI) measurement, the fourth resource including resources on a second time domain unit, the second time domain unit being a full-duplex time domain unit; transmitting third information, the third information being used to indicate a first switching time and / or a number of switching operations; the first switching time being: the time required to switch between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource; the number of switching operations being: the number of times switching between downlink transmission on a first frequency domain resource and CLI measurement on a second frequency domain resource on a plurality of consecutive second time domain units; wherein, the first frequency domain resource is a resource on a second time domain unit used for downlink transmission, and the second frequency domain resource is a resource on a second time domain unit used for uplink transmission.
[0044] In one possible implementation, the method is performed by a first communication device. The first communication device can be understood as a terminal device. Furthermore, the first communication device can be the terminal device itself, or a component applied to the terminal device (e.g., a chip, chip system, circuit, software and / or hardware module, etc.).
[0045] Receiving the seventh message can be performed before or after sending the third message.
[0046] In one scenario, the fourth resource is the resource range for CLI measurements performed by the terminal device. The terminal device and the network device can determine the resources actually measured by the terminal device when performing CLI measurements based on the third information.
[0047] In another scenario, the fourth resource is the resource actually measured when the terminal device performs CLI measurements; that is, the fourth resource configured by the network device is configured based on the third information.
[0048] The interference measurement method of this application allows the terminal device and network device to determine the resources actually measured when the terminal device performs CLI measurements based on a first handover time and / or the number of handovers. The first handover time can be a handover time supported by the terminal device, and the number of handovers can be a number of handovers determined under the premise of conforming to the handover time supported by the terminal device.
[0049] In this way, both the terminal device and the network device can determine the actual resources being measured, thereby determining which resources the CLI reported by the terminal device represents for inter-UE CLI. Furthermore, the switching of the filtering bandwidth between the first and second frequency domain resources during CLI measurement by the terminal device also meets the capabilities of the terminal device.

Furthermore, since the first measurement resource is the measurement resource in one or more time slots closest to the third resource among multiple time slot measurement resources, the sixth CLI accurately reflects the inter-UE CLI on the current channel. This allows network devices to combine the sixth CLI for more accurate interference avoidance.

[0136] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0137] To facilitate the understanding of the embodiments of the present application, the following points are first explained as follows:
[0138] First, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and effects. For example, the first value and the second value are only used to distinguish different values, and do not limit their order. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and the terms such as "first" and "second" do not necessarily limit them to be different.
[0139] It should be noted that in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in the present application should not be construed as more preferred or more advantageous than other embodiments or design solutions.确切而言,使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。Rather, the use of words such as "exemplarily" or "for example" aims to present relevant concepts in a specific manner.
[0140] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (s) or plural item (s). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.
[0141] Second, "send" and "receive" in the embodiments of the present application represent the direction of signal transmission. For example, "sending information to the second device" can be understood as the destination of the information being the second device, which can include directly sending through the air interface, and also include indirectly sending through the air interface by other units or modules. "Receiving configuration information from the charging" can be understood as the source of the configuration information being the second device, which can include directly receiving from the second device through the air interface, and can also include indirectly receiving from the second device through the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.
[0142] In other words, sending and receiving can be done between devices, such as between a second device and a first device; or it can be done within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.
[0143] 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.
[0144] Third, for ease of understanding, this document provides several examples of messages such as requests, responses, reports, information, or signals, such as the first to sixth messages. The order and names of these messages are merely examples and should not constitute any limitation on this application.
[0145] Fourth, in the embodiments of this application, "instruction" can include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be indicated are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol predefined) arrangement of various pieces of information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction.
[0146] It is understandable that, for the sender of the instruction information, the instruction information can be used to indicate the information to be indicated, and for the receiver of the instruction information, the instruction information can be used to determine the information to be indicated.
[0147] Fifth, the tables in the embodiments of this application are merely examples. The values of the information in each table are only examples and can be configured to other values; this application is not limited thereto. The tables do not limit the scope of protection of this application. For example, appropriate modifications and adjustments can be made based on the tables described above, such as splitting, merging, etc. Furthermore, the parameter names shown in the headings of each table can also use other names understandable to the communication device, and the values or representations of the parameters can also be other values or representations understandable to the communication device. Moreover, 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.
[0148] Sixth, in the embodiments of this application, descriptions such as "when," "under the circumstances," "if," and "if" all refer to the fact that the device (e.g., network device or terminal device) will make corresponding processing under certain objective circumstances. They are not time limits, nor do they require the device (e.g., network device or terminal device) to make a judgment action when implementing it, nor do they mean that there are other limitations.
[0149] Seventh, the predefined terms in this application can be understood as: definition, pre-defined, storage, pre-storage, pre-negotiation, pre-configuration, solidification, or pre-firing.
[0150] Eighth, the term "storage" in this application can refer to storage in one or more memory devices. These memory devices can be separate installations or integrated into an encoder, decoder, processor, or communication device. Alternatively, some memory devices can be separately installed, while others can be integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this.
[0151] The technical solutions of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, 5th Generation (5G) systems, or New Radio (NR) systems, and future communication systems.
[0152] The terminal equipment in this application embodiment can also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.
[0153] Terminal devices can be devices that provide voice / data connectivity to users, such as handheld devices with wireless connectivity, in-vehicle devices, etc. Currently, examples of terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), point-of-sale (POS) machines, customer-premises equipment (CPEs), light user equipment (UEs), reduced capability UEs (REDCAP UEs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving vehicles, wireless terminals in remote medical surgery, 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). This application does not limit the scope to include devices such as personal assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, or terminal devices in future evolved public land mobile networks (PLMNs).
[0154] By way of example and not limitation, in this application, the terminal device can be a terminal device in an Internet of Things (IoT) system. The Internet of Things is an important component of future information technology development. Its main technical characteristic is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. Exemplarily, the terminal device in the embodiments of this application can be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that apply wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that can be worn directly on the body or integrated into a user's clothing or accessories. Wearable devices are not merely hardware devices; they can also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those with comprehensive functions, large size, and the ability to achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those focused on a specific application function and requiring the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.
[0155] By way of example and not limitation, in the embodiments of this application, the terminal device can also be a terminal device in machine-type communication (MTC). Furthermore, the terminal device can also be an on-board module, on-board component, on-board chip, or on-board unit, etc., built into a vehicle as one or more components or units. The vehicle can implement the methods provided in this application through the built-in on-board module, on-board component, on-board chip, or on-board unit, etc. Therefore, the embodiments of this application can also be applied to vehicle networking, such as vehicle to everything (V2X), long term evolution-vehicle (LTE-V) technology, and vehicle-to-vehicle (V2V) technology.
[0156] The network devices involved in this application may include access network devices.
[0157] Access network equipment, also known as radio access network (RAN) equipment, is a device that communicates with terminal devices and has wireless transceiver capabilities. RAN equipment provides wireless communication services, allowing terminals to access the wireless network. RAN equipment can be a node in the radio access network, often referred to as a RAN node.
[0158] In one possible scenario, a RAN node can be a base station (BS), an evolved NodeB (eNodeB), a transmission reception point (TRP), a home evolved NodeB (or home Node B, HNB), a Wi-Fi access point (AP), a mobile switching center, a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a future mobile communication system, or a base station in a future mobile communication system. A RAN node can also be a device that performs base station functions in device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, machine-to-machine (M2M) communication systems, and internet-to-things (IoT) communication systems. A RAN node can also be a RAN node in a non-terrestrial network (NTN), meaning that a RAN node can be deployed on a high-altitude platform or a satellite. RAN nodes can be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, etc., or radio controllers in cloud radio access network (CRAN) scenarios, or nodes in open radio access network (O-RAN or ORAN) scenarios. Optionally, RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, RAN nodes can be roadside units (RSUs). Of course, RAN nodes can also be nodes in the core network.
[0159] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. 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).
[0160] 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 the ORAN system, CU can also be called open CU (O-CU), DU can also be called open DU (O-DU), CU-CP can also be called open CU-CP (O-CU-CP), CU-UP can also be called open CU-UP (O-CU-UP), and RU can also be called open RU (O-RU).
[0161] Any one of the CU (or CU-CP, CU-UP), DU, and RU units can be implemented through software modules, hardware modules, or a combination of software and hardware modules. That is, the wireless access network device in this application can be a virtualized device, for example, implemented through general-purpose hardware and instantiated virtualization functions, or dedicated hardware and instantiated virtualization functions. The general-purpose hardware can be a server, such as a cloud server.
[0162] To facilitate understanding of the embodiments of this application, the communication system applicable to the embodiments of this application will be described in detail first with reference to FIG1.
[0163] Figure 1 is a schematic diagram of the architecture of a communication system 1000 applicable to the method provided in the embodiments of this application. As shown in Figure 1, the communication system 1000 includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300.
[0164] The wireless access network 100 may include at least one access network device (110a and 110b in Figure 1) and at least one terminal device (120a-120j in Figure 1).
[0165] Terminal devices can connect to access network devices wirelessly, while access network devices can connect to the core network wirelessly or via wired connections. Core network devices and access network devices can be independent, separate physical devices, or they can integrate the functions of core network devices and the logical functions of access network devices onto the same physical device. Alternatively, a single physical device can integrate some core network device functions and some access network device functions. Terminal devices and access network devices can connect to each other via wired or wireless connections.
[0166] It should be understood that the connection between devices can also be understood as the ability of devices to communicate with each other. For example, the connection between access network devices means that access network devices can communicate with each other.
[0167] Wireless access network devices and terminal devices, as well as access network devices and terminal devices, can communicate using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can occur using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.
[0168] Among them, the wireless access network equipment can be a base station deployed in the air, such as a satellite base station 110a; or it can be a base station deployed indoors, such as a micro base station or an indoor station 110b.
[0169] The terminal equipment can be terminal equipment deployed in the air, such as the helicopter or drone 120i in Figure 1; or it can be terminal equipment deployed on the ground, such as mobile phones 120a, 120e, 120f, 120j, vehicle 120b, computer 110b, and printer 120h in Figure 1.
[0170] Access network equipment and terminal equipment can be fixed in location or mobile. For example, access network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and artificial satellites.
[0171] The roles of access network devices and terminal devices can be relative. For example, the helicopter or drone 100i in Figure 1 can be configured as a mobile base station. For those 120j that access the wireless access network 100 via 120i, 120i is a base station; but for 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via an interface protocol between access network devices. In this case, relative to 110a, 120i is also a base station. Therefore, both wireless access network devices and terminal devices can be collectively referred to as communication devices. 110a, 110b, and 120a-120j in Figure 1 can be called communication devices with their respective corresponding functions, such as communication devices with base station functions or communication devices with terminal functions.
[0172] It should be understood that Figure 1 is only a schematic diagram, and the communication system may also include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1. The embodiments of this application do not limit this.
[0173] The aforementioned communication devices, such as the access network device or terminal device in Figure 1, can be configured with multiple antennas. These multiple antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Additionally, each communication device also includes a transmitter chain and a receiver chain, which, as will be understood by those skilled in the art, may include multiple components related to signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, or antennas). Therefore, access network devices and terminal devices can communicate via multi-antenna technology.
[0174] Optionally, the communication system 1000 may also include other network entities such as a network controller and a mobility management entity, but the embodiments of this application are not limited thereto.
[0175] It should also be understood that the method provided in the embodiments of this application can be applied to a variety of communication systems, including 5G new radio (NR) systems. Communication system 1000 is only an example. This application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices contained in each communication system.
[0176] To facilitate understanding of the solutions in this application, some technical terms used in this application are introduced below.
[0177] 1. Resource element (RE) and resource element (RB)
[0178] It is the basic unit used to describe the allocation of wireless resources.
[0179] Here, RE is the smallest resource unit, representing a combination of an OFDM symbol in the time domain and a subcarrier in the frequency domain.
[0180] An RB is a resource unit consisting of multiple consecutive subcarriers in the frequency domain. In the frequency domain, an RB typically contains 12 subcarriers.
[0181] It should be understood that in the embodiments of this application, OFDM symbols may also be referred to as symbols, etc.; and the number of symbols included in the time domain of a time slot shown in the embodiments of this application is only for illustration (e.g., 14 symbols). In actual application scenarios, the number of symbols included in the time domain of a time slot may also be replaced with others, and this application does not make specific limitations on this.
[0182] 2. Reference signal received power (RSRP) and received signal strength indication (RSSI)
[0183] RSRP can refer to the average power of the signal received by a terminal device in a wireless network.
[0184] RSSI is an indicator used to measure the strength of radio signals. RSSI is typically calculated by the receiver when it receives a radio signal.
[0185] 3. Channel State Information (CSI) Report
[0186] CSI reports can be sent from terminal devices to network devices. They are used by network devices to obtain downlink channel conditions, such as interference. One CSI report can be used by a terminal device to provide at least one CSI response; different CSIs can correspond to different frequency bands, different transmission assumptions, or different reporting modes.
[0187] 4. Frequency division duplex (FDD)
[0188] A duplex mode. When using (or configuring) FDD mode, uplink and downlink transmissions can be performed simultaneously on different frequency domain resources on the same time domain resources.
[0189] For example, as shown in Figure 2, “D” can be understood as downlink (DL), and downlink transmission can be performed on the DL timeslot; “U” can be understood as uplink (UL), and uplink transmission can be performed on the UL timeslot.
[0190] In slot 0, downlink transmission can occur on the DL bandwidth part (BWP); uplink transmission can also occur on the UL BWP in slot 0. The DL BWP and UL BWP are located on different carriers and are separate in the frequency domain. Similarly, in slots 1 and 2, uplink and downlink transmissions can occur simultaneously on different frequency domain resources.
[0191] 5. Time Division Duplex (TDD)
[0192] A duplex mode. When using (or configuring) TDD mode, uplink and downlink transmissions can be performed separately on different time domain resources on the same frequency domain resources.
[0193] For example, as shown in Figure 3, “D” can be understood as DL, where downlink transmission can be performed on the DL time slot; “U” can be understood as UL, where uplink transmission can be performed on the UL time slot; and “F” can be understood as flexible, where uplink or downlink transmission can be performed on the flexible time slot, but uplink and downlink transmission cannot be performed simultaneously.
[0194] The DL BWP and UL BWP share the same center frequency, and their bandwidths can be the same or different. At any given time, the terminal device can only perform either uplink or downlink transmission. For example, in slot 0, only downlink transmission is possible; in slot 4, only uplink transmission is possible. Slot 3 is a flexible time slot, meaning it can be used for either uplink or downlink transmission, but not both simultaneously.
[0195] Typically, the smallest granularity for uplink / downlink transmission switching is a symbol. Slot 3 is a flexible time slot, which can consist of 12 or 14 symbols. Of these 12 or 14 symbols, the first M symbols are used for downlink transmission; the last N symbols are used for uplink transmission; and the middle 14-MN (or 12-MN) symbols are flexible symbols, where 0 <= M <= 14 (or 12), 0 <= N <= 14 (or 12), and M+N <= 14 (or 12). Flexible symbols can be used for both uplink and downlink transmission, and the specific transmission direction can be notified to the terminal device by the network device through radio resource control (RRC) signaling or downlink control information (DCI) scheduling.
[0196] It should be understood that the indices shown in the embodiments of this application, such as the index of time slot, the index of symbol, the index of subcarrier, or the index of RB, are all examples. In actual application scenarios, each index can be replaced with others, and this application does not make any specific limitations on this.
[0197] 6. Subband Full Duplex (SBFD)
[0198] Because TDD (Time-of-Depth) transmission cannot perform uplink and downlink transmissions simultaneously. For example, referring to Figure 3, only downlink transmission can occur in slot 0, which may lead to increased uplink transmission latency. To solve the latency problem of TDD, SBFD (Short-Side Flow Diversion) can be used to achieve simultaneous uplink and downlink transmissions.
[0199] The core idea of SBFD is that uplink and downlink transmission resources can be configured simultaneously on certain time-domain units (such as symbols or time slots) using TDD. That is, on certain time-domain units (such as symbols or time slots) using TDD, some resources in the DL BWP can be uplink transmission resources, which can be called UL subbands or uplink-available resources; and some resources in the DL BWP can be downlink transmission resources, which can be called DL subbands or downlink-available resources.
[0200] In one example, a network device can simultaneously configure uplink and downlink transmission resources on certain time slots using TDD (Time Divided) architecture. This is illustrated in Figure 4, where "D" can be understood as DL (Deep Link), "U" as UL (Uniform Link), and "F" as flexible. In certain time slots, such as slots 0 to 3, a frequency domain resource exists within the DL BWP (BWP in the figure). Uplink transmission can be performed on this frequency domain resource, thus enabling uplink transmission from slot 0 to slot 3 and reducing uplink latency. This frequency domain resource used for uplink transmission is typically referred to as the UL subband or uplink-available resource. The remaining frequency domain resource used for downlink transmission is typically referred to as the DL subband or downlink-available resource.
[0201] In this way, network devices can perform uplink and downlink transmissions simultaneously on slots 0 to 3. Terminal devices can also perform uplink and downlink transmissions simultaneously on slots 0 to 3 (i.e., full-duplex terminal devices); or, terminal devices can perform only uplink or downlink transmissions (half-duplex terminal devices).
[0202] Alternatively, as shown in slot 3, a flexible subband (represented by "F" in the diagram) can also exist in the BWP, which can be used for both uplink and downlink transmission. Or, similar to slot 2, slot 3 has no flexible subband, only downlink and uplink subbands.
[0203] In another example, network devices can simultaneously configure uplink and downlink transmission resources on certain symbols using TDD. As shown in Figure 5, "D" can be understood as DL; "U" as UL; and "F" as flexible. On certain symbols, such as symbols 0 to 3, a frequency domain resource exists within the DL BWP, on which uplink transmission can be performed. This reduces uplink latency, allowing uplink transmission on symbols 0 to 3. This frequency domain resource can be called the UL subband or uplink-available resource. The remaining frequency domain resources used for downlink transmission can be called the DL subband or downlink-available resource. Thus, network devices can perform uplink and downlink transmissions simultaneously on symbols 0 to 3. Terminal devices can also perform uplink and downlink transmissions simultaneously on symbols 0 to 3 (i.e., full-duplex terminal devices); or, terminal devices can perform only uplink or downlink transmissions (half-duplex terminal devices).
[0204] Alternatively, as shown in symbol 3, a flexible subband (represented by "F" in the figure) can also exist in the BWP, which can be used for both uplink and downlink transmission.
[0205] It should be understood that Figures 4 and 5 are merely examples. In actual application scenarios, the UL subband may not be located between two DL subbands. In some possible scenarios, the BWP may also include one DL subband and one UL subband, and the center frequency of the DL subband may be greater than the center frequency of the UL. That is, in the frequency domain direction, the DL subband is located at a relatively higher frequency, and the UL subband is located at a relatively lower frequency, as shown in the time domain unit in Figure 11 below. In this case, it can be understood that the frequency domain resource with the lowest frequency in the DL BWP on part of the TDD time domain unit is configured as uplink transmission resource, that is, the UL subband or uplink available resource, while the remaining part is still used for downlink transmission resource, that is, the DL subband or downlink available resource. Alternatively, the center frequency of the DL subband may also be less than the center frequency of the UL. That is, in the frequency domain direction, the UL subband is located at a relatively higher frequency, and the DL subband is located at a relatively lower frequency. In this case, it can be understood that the frequency domain resource with the highest frequency in the DL BWP on a portion of the TDD time domain unit is configured as uplink transmission resource, i.e., UL subband, while the remaining part is still used for downlink transmission resource, i.e. DL subband. This application does not make specific limitations in this regard.
[0206] It should also be understood that, in the embodiments of this application, in time-domain units that do not employ the SBFD method, the time-domain unit used for uplink transmission can also be called a UL time-domain unit; and the time-domain unit used for downlink transmission can also be called a DL time-domain unit. This application does not impose specific limitations in this regard.
[0207] It should also be understood that, in the embodiments of this application, a time-domain unit can be understood as the granularity of a time-domain resource, and may also be referred to as a time unit, etc. Furthermore, a time-domain unit can be, but is not limited to, symbols, time slots, subframes, system frames, etc., and can also be the granularity of other time-domain resources; this application does not specifically limit this.
[0208] 7. Cross-link interference (CLI)
[0209] In wireless communication systems, CLI typically refers to signal interference between different links. CLI includes two types: interference between network devices (such as base stations), which can be called inter-gNB CLI, i.e., interference generated between network devices when they transmit signals, such as the interference caused by downlink transmission of a network device to uplink reception of an adjacent network device; and interference between terminal devices, which can be called inter-UE CLI, i.e., interference generated between terminal devices when they transmit signals, such as the interference caused by uplink transmission of a terminal device to downlink reception of an adjacent terminal device.
[0210] It should be understood that in the embodiments of this application, adjacent network devices can also be understood as network devices that are close to each other, such as network devices that are less than a certain threshold apart; adjacent terminal devices can also be understood as terminal devices that are close to each other, such as terminal devices that are less than a certain threshold apart, and adjacent terminal devices can be in the same cell or in adjacent cells. For the sake of brevity, this will not be elaborated further below.
[0211] (1) CLI when using TDD (or CLI generated when configuring TDD)
[0212] For adjacent cells using TDD, the transmission directions configured in the same time domain unit (taking a time slot as an example) may be different. In that time slot, adjacent cells will perform uplink and downlink transmissions simultaneously, which may result in intra-band CLI.
[0213] For example, as shown in Figure 6, network device 1 and network device 2 can be understood as adjacent network devices; UE 1 and UE 2 can be understood as adjacent terminal devices. Furthermore, the cell where UE 1 is located and the cell where UE 2 is located can be adjacent cells.
[0214] In this configuration, network device 1 configures slot 2 as a downlink time slot, meaning a time slot used for downlink transmission. Network device 1 can then send downlink signals to UE 1 via slot 2; correspondingly, UE 1 can receive downlink signals from network device 1 via slot 2. Similarly, network device 2 configures slot 2 as an uplink time slot, meaning a time slot used for uplink transmission. UE 2 can then send uplink signals to network device 2 via slot 2; correspondingly, network device 2 can receive uplink signals from UE 2 via slot 2.
[0215] Therefore, in slot 2, network device 1 sends a downlink signal while network device 2 simultaneously receives an uplink signal. Because the distance between network device 1 and network device 2 is small, the downlink signal sent by network device 1 may interfere with the uplink signal received by network device 2. This interference can be understood as inter-gNB CLI.
[0216] Similarly, in slot 2, UE 1 receives downlink signals while UE 2 simultaneously transmits uplink signals. Due to the small distance between UE 1 and UE 2, the uplink signals transmitted by UE 2 may interfere with UE 1's reception of downlink signals. This interference can be understood as inter-UE CLI.
[0217] It should be noted that for cells using TDD, terminal devices within the same cell may simultaneously perform uplink or downlink transmissions in the same time slot. Therefore, there may be no inter-UE CLI between terminal devices within the same cell. Thus, in a TDD cell, inter-UE CLI between terminal devices within that cell can also be understood as inter-cell interference. For example, referring to Figure 6, UE 1 and UE 2 are in different cells. The CLI caused by UE 2 sending uplink signals to UE 1 receiving downlink signals can be understood as inter-cell interference.
[0218] (2) CLI when using SBFD (or CLI generated when configuring SBFD)
[0219] For adjacent cells using SBFD, uplink and downlink transmissions occur simultaneously in the same time domain unit (e.g., time slot or symbol). Therefore, for adjacent terminal devices, uplink signals on the UL subband may leak onto the adjacent DL subband, and downlink signals on the DL subband may also leak onto the adjacent UL subband, potentially resulting in inter-band CLI.
[0220] When an uplink signal on the UL subband leaks into the adjacent DL subband, the closer the frequency in the DL subband is to the UL subband, the greater the power of the leaked signal is likely to be. For example, referring to Figure 7, the DL and UL subbands shown in Figure 7 can be understood as frequency domain resources on a single time-domain unit (such as a symbol or time slot). A guard band (GB) can also be set between the DL and UL subbands. Uplink signals transmitted by the terminal device on the UL subband will leak into the DL subband. For example, as shown by curve 701, the closer the frequency in the DL subband is to the UL subband, the greater the power of the leaked uplink signal. Similarly, when a downlink signal on the DL subband leaks into the adjacent UL subband, the closer the frequency in the UL subband is to the DL subband, the greater the power of the leaked signal is likely to be.
[0221] For adjacent terminal devices located at the cell edge (which may be in the same cell or adjacent cells), when the uplink transmission power is high, especially in medium-to-high load scenarios, UE CLI can cause a significant drop in the downlink reception performance of the terminal device performing downlink transmission, and in severe cases, it can even completely block its downlink reception.
[0222] Furthermore, for terminal devices located at the cell edge, their neighboring terminal devices may be those located in the same or adjacent cells. This means that terminal devices located at the cell edge may experience both intra-cell interference and inter-cell interference.
[0223] For example, as shown in Figure 8, network device 1 and network device 2 can be understood as adjacent network devices; UE 1 and UE 2 can be understood as adjacent terminal devices located in the same cell. UE 1 and UE 3 can be understood as adjacent terminal devices located in different cells, and the cell where UE 1 is located and the cell where UE 3 is located can be adjacent cells.
[0224] Referring to Figure 8, within the same time domain unit (such as a symbol or time slot), this time domain unit adopts the SBFD method and can be called an SBFD time domain unit. Within an SBFD time domain unit, both network device 1 and network device 2 can simultaneously perform uplink and downlink transmissions.
[0225] As shown in Figure 8, in this SBFD time domain unit, UE 1 can send uplink signals to network device 1 in the UL subband; correspondingly, network device 1 can receive uplink signals from UE 1 in the UL subband. Network device 1 can send downlink signals to UE 2 in the DL subband; correspondingly, UE 2 can receive downlink signals from network device 1 in the DL subband. UE 3 can send uplink signals to network device 2 in the UL subband; correspondingly, network device 2 can receive uplink signals from UE 3 in the UL subband.
[0226] Therefore, in this time-domain unit, the downlink signal transmitted by network device 1 on the DL subband may interfere with the uplink signal received by network device 2 on the UL subband. This interference can be understood as inter-gNB CLI. Similarly, the downlink signal transmitted by network device 2 on the DL subband may interfere with the uplink signal received by network device 1 on the UL subband. This interference can also be understood as inter-gNB CLI.
[0227] Similarly, in this SBFD time-domain unit, for UE 1 and UE 2, UE 1 transmitting uplink signals on the UL subband may interfere with UE 2 receiving downlink signals on the DL subband. This interference can be understood as inter-UE CLI. Furthermore, since UE 1 and UE 2 belong to the same cell, this interference can also be understood as intra-cell interference.
[0228] For UE 2 and UE 3, UE 3's uplink signal transmission on the UL subband may interfere with UE 2's downlink signal reception on the DL subband. This interference can be understood as inter-UE CLI. Furthermore, since UE 2 and UE 3 belong to different cells, this interference can also be understood as inter-cell interference.
[0229] Therefore, in the SBFD time domain unit (such as SBFD time slot or SBFD symbol), UE-to-UE CLI includes intra-cell interference and inter-cell interference.
[0230] The higher the power of the uplink signals transmitted by UE 1 and / or UE 2, the greater the interference to the downlink signal reception of UE 2. Furthermore, as the interference increases, the downlink reception performance of UE 2 may degrade significantly, and in severe cases, its downlink reception may be completely blocked.
[0231] To reduce inter-UE CLI and thus improve the communication performance of terminal devices, terminal devices can perform interference measurements, also known as CLI measurements, and report the measurement results to the network device. This allows the network device to use the measurement results for scheduling, such as scheduling adjacent terminal devices to avoid simultaneous uplink and downlink transmissions in the same time domain unit. This prevents adjacent terminal devices from performing uplink transmissions while others perform downlink transmissions in the same time domain unit, thereby reducing inter-UE CLI caused by simultaneous uplink and downlink transmissions by adjacent terminal devices.
[0232] For example, referring to Figure 8, suppose network device 1 receives a measurement result from UE 2, and this measurement result indicates that the inter-UE CLI exceeds a certain threshold. Then, the network device can schedule UE 2 and its neighboring terminal devices. For example, when UE 2 is receiving downlink signals, network device 1 can schedule UE 1, the neighboring terminal device of UE 2, not to perform uplink transmission, so that UE 2 will not be interfered with by the uplink signals sent by UE 1 when receiving downlink signals, thereby reducing the inter-UE CLI of UE 2 and improving the reception performance of UE 2.
[0233] However, as known above, in the SBFD time domain unit (such as SBFD time slot or SBFD symbol), inter-UE CLI includes inter-cell interference, such as the interference of UE 3 sending uplink signals to UE 2 receiving downlink signals; it also includes intra-cell interference, such as the interference of UE 1 sending uplink signals to UE 2 receiving downlink signals. If UE 2's inter-UE CLI is mainly inter-cell interference, for example, the interference of UE 3 sending uplink signals to UE 2 receiving downlink signals is significantly greater than the interference of UE 1 sending uplink signals to UE 2 receiving downlink signals (e.g., the difference is greater than a certain threshold), then even if network device 1 schedules UE 1, the adjacent terminal device of UE 2 in the same cell, not to perform uplink transmission when UE 2 receives downlink signals, UE 2's inter-UE CLI may still be large.
[0234] Conversely, if the inter-UE CLI of UE 2 is mainly intra-cell interference, for example, the interference of the uplink signal sent by UE 1 on the downlink signal received by UE 2 is significantly greater than the interference of the uplink signal sent by UE 3 on the downlink signal received by UE 2 (such as the difference being greater than a certain threshold), then even if network device 1 instructs network device 2 to schedule UE 3, the neighboring terminal device of UE 2, not to perform uplink transmission when UE 2 receives downlink signals, the inter-UE CLI of UE 2 may still be large.
[0235] Therefore, when network devices cannot determine the type of CLI interference between UEs (such as inter-cell interference and / or intra-cell interference), the effectiveness of interference avoidance by network devices may be poor.
[0236] Therefore, there is an urgent need to provide a method that enables network devices to determine the type of CLI interference between UEs, thereby improving the effectiveness of network devices in interference avoidance.
[0237] In view of this, this application provides an interference measurement method in which a terminal device performs CLI measurements on a first resource on a non-SBFD time-domain unit and on a second resource on an SBFD time-domain unit, respectively, to determine a first CLI measured on the first resource and a second CLI measured on the second resource. Furthermore, the terminal device can report the first CLI and the second CLI to a network device.
[0238] As shown in Figure 8, in non-SBFD time domain units, the interference type of inter-UE CLI is inter-cell interference; and as shown in Figure 8, in SBFD time domain units, inter-UE CLI includes intra-cell interference and inter-cell interference. Therefore, the first CLI can reflect the magnitude of inter-cell interference experienced by the terminal device; the second CLI can reflect the magnitude of both inter-cell and intra-cell interference experienced by the terminal device. Thus, through the first and second CLIs, the network device can determine the primary type of interference in the inter-UE CLI.
[0239] For example, if the first CLI is large (e.g., greater than a certain threshold) and the first CLI is close to the second CLI (e.g., the difference between them is less than a certain threshold), it indicates that the CLI between UEs is likely mainly inter-cell interference, while intra-cell interference is relatively small. In this case, network devices can schedule terminal devices within the same cell normally, because the terminal devices within the same cell will not cause significant interference; the interference mainly comes from neighboring cells.
[0240] When the first CLI is small (e.g., less than a certain threshold) and the second CLI is much larger than the first CLI (e.g., the difference between the two is greater than a certain threshold), it indicates that the CLI between UEs is mainly intra-cell interference, while inter-cell interference is relatively small. In this case, the network device can schedule adjacent terminal devices in the same cell to perform uplink and downlink transmissions at different times in the same time domain. That is, for adjacent terminal devices in the same cell, there is no phenomenon where some terminal devices perform uplink transmissions while others perform downlink transmissions simultaneously.
[0241] Therefore, this approach helps network devices determine the type of CLI interference between UEs, enabling them to more accurately schedule terminal devices (i.e., perform interference avoidance) to reduce CLI between UEs. This improves the effectiveness of interference avoidance by network devices, thereby enhancing the communication performance of terminal devices.
[0242] The interference measurement method of this application will now be described in detail with reference to Figures 9 to 19. The embodiments shown in this application illustrate the switching method provided by this application from the perspective of device interaction. The specific form and number of each device shown are merely examples and should not constitute any limitation on the implementation of the method provided in this application. The interference measurement method of this application will now be described in detail using terminal devices and network devices as examples.
[0243] It should be understood that the terminal device can be replaced by a terminal unit (or a first communication unit), and the first communication unit can be the terminal device itself, or a chip, chip system or processor that supports the implementation of the interference measurement method, or a logic module or software that can implement all or part of the functions of the terminal device; the network device can include access network equipment, and the network device can be replaced by a network unit (or a second communication unit), and the second communication unit can be the network device itself, or a chip, chip system or processor that supports the implementation of the interference measurement method, or a logic module or software that can implement all or part of the functions of the network device. This application does not make specific limitations in this regard.
[0244] Figure 9 is a flowchart illustrating an interference measurement method 900 provided in an embodiment of this application. Method 900 is applicable to a communication system 1000 and includes the following steps:
[0245] S901, the network device sends first information to the terminal device. The first information is used to configure first resources and second resources. The first resources are used to measure the first CLI on the first time domain unit and the second resources are used to measure the second CLI on the second time domain unit. The first time domain unit is a half-duplex time domain unit and the second time domain unit is a full-duplex time domain unit. Correspondingly, the terminal device receives the first information from the network device.
[0246] The first and second resources can be understood as the time-frequency domain resources configured by the network device for CLI measurements. These resources can also be referred to as measurement resources, interference measurement resources, CLI measurement resources, etc.
[0247] The first resource and the second resource can be understood as time-frequency domain resources on different types of time-domain units; or, the first resource and the second resource can also be understood as different types of time-frequency domain resources.
[0248] The first time-domain unit and the second time-domain unit can be understood as time-domain units of different types.
[0249] The first time domain unit being a half-duplex time domain unit can be interpreted as follows: In the first time domain unit, the terminal device and / or network device can perform uplink or downlink transmission, but not both simultaneously. When uplink transmission is possible in the first time domain unit, it can also be called a UL time domain unit; when downlink transmission is possible in the first time domain unit, it can also be called a DL time domain unit. Alternatively, it can be understood as the first time domain unit being a time domain unit used for either uplink or downlink transmission, or the first time domain unit having only resources for uplink transmission, or only resources for downlink transmission.
[0250] The first time-domain unit being a half-duplex time-domain unit can also be understood as: the first time-domain unit adopts TDD mode (or is configured with TDD, etc.), and can also be called a TDD time-domain unit; it can also be understood as: the first time-domain unit does not adopt SBFD mode (or is not configured with SBFD, etc.), and can also be called a non-SBFD time-domain unit. Therefore, when the time-domain unit is a time slot, the first time-domain unit can also be called a non-SBFD time slot; when the time-domain unit is a symbol, the first time-domain unit can also be called a non-SBFD OFDM symbol (or simply a non-SBFD symbol). Of course, besides time slots and symbols, time-domain units can also be sub-time slots, subframes, radio frames, etc., and this application does not specifically limit them.
[0251] For example, referring to FIG4, the first time domain unit may include time slot 4; or referring to FIG5, the first time domain unit may include one or more symbols from symbol 4 to symbol 11.
[0252] It should be noted that the first time-domain unit refers to a time-domain unit that does not employ the SBFD method, and the first time-domain unit may include one or more time-domain units. When the first time-domain unit includes multiple time-domain units, it may include DL time-domain units and / or UL time-domain units.
[0253] It should also be noted that, since the first resource is a time-frequency domain resource on the first time-domain unit, the use of the first resource to measure the first CLI on the first time-domain unit can also be replaced by: the terminal device measuring the first CLI on the first resource on the first time-domain unit. Furthermore, when the first time-domain unit is a DL time-domain unit (such as a DL symbol), the first resource can also be represented by the DL time-domain unit or resources on the DL time-domain unit; when the first time-domain unit is a UL time-domain unit (such as a UL symbol), the first resource can also be represented by the UL time-domain unit or resources on the UL time-domain unit.
[0254] A full-duplex second time domain unit can be interpreted as a unit where uplink and downlink transmissions can occur simultaneously. A full-duplex second time domain unit can also be understood as a unit that uses SBFD (or is configured with SBFD), and can be called an SBFD time domain unit. When the time domain unit is a timeslot, the second time domain unit can also be called an SBFD timeslot; when the time domain unit is a symbol, the second time domain unit can also be called an SBFD OFDM symbol (or simply SBFD symbol). Alternatively, it can be understood as a time domain unit used for both uplink and downlink transmissions. It should be noted that while network devices can perform uplink and downlink transmissions simultaneously on the second time domain unit, terminal devices can not perform uplink and downlink transmissions simultaneously; that is, a terminal device can perform either uplink or downlink transmissions on the second time domain unit. Alternatively, it can be understood as a second time domain unit having resources for both uplink and downlink transmissions.
[0255] For example, referring to FIG4, the second time domain unit may include one or more time slots from time slot 0 to time slot 3; or, referring to FIG5, the first time domain unit may include one or more symbols from symbol 0 to symbol 3.
[0256] It should be noted that the second time-domain unit refers to a time-domain unit using the SBFD method. Furthermore, the second time-domain unit may include one or more time-domain units, and the BWP on each time-domain unit may include: DL subband and / or UL subband. The DL subband can be understood as a resource that can be used for downlink transmission, and the UL subband can be understood as a resource that can be used for uplink transmission.
[0257] It should also be noted that since the second resource is a time-frequency domain resource on the second time-domain unit, the second resource used to measure the second CLI on the second time-domain unit can also be replaced by: the terminal device measuring the second CLI on the second resource on the second time-domain unit.
[0258] It is understandable that, based on the first and second resources configured on the network device, the terminal device can perform CLI measurements on the first resource to obtain the first CLI; and can perform CLI measurements on the second resource to obtain the second CLI.
[0259] For example, referring to FIG10, the first time domain unit may include time domain unit 0 and / or time domain unit 5, and the first resource may include some or all of the resources in the BWP on time domain unit 0 and / or time domain unit 5; the second time domain unit may include time domain units 1 to 4, and the second resource may be the resources on time domain units 1 to 4, and the second resource may include some or all of the resources in the DL subband and / or the UL subband on time domain units 1 to 4.
[0260] Therefore, the first CLI can be determined by the terminal device through CLI measurement on the first resource in time domain unit 0 and / or time domain unit 5; the second CLI can be determined by the terminal device through CLI measurement on the second resource in time domain units 1 to 4.
[0261] S902, the terminal device sends second information to the network device, the second information being used to indicate the first CLI and the second CLI; correspondingly, the network device receives the second information from the terminal device.
[0262] The second piece of information can be included in the first report. The first report can be understood as a measurement report or a CSI report, etc. That is, the second piece of information can be included in the CSI report.
[0263] Taking the first report as a CSI report as an example, in the first possible implementation, the first CLI and the second CLI can be reported through a single CSI report. That is, the second information is carried in the same CSI report, meaning that a single CSI report carries both the first CLI and the second CLI.
[0264] Both the first CLI and the second CLI can be understood as uplink control information (UCI). In a CSI report, the first CLI can be included first, or the second CLI can be included first.
[0265] Furthermore, a single CSI report can occupy a CSI processing unit (CPU).
[0266] In a second possible implementation, the first CLI and the second CLI can be reported through different CSI reports. That is, the second information includes a first sub-information and a second sub-information, the first sub-information is used to indicate the first CLI, and the second sub-information is used to indicate the second CLI; then the first sub-information is carried in the first CSI report, and the second sub-information is carried in the second CSI report, and the first CSI report and the second CSI report are different CSI reports.
[0267] In order for network devices to distinguish between the first CLI and the second CLI, the first CSI report may also carry information for indicating the first resource (or the first time domain unit); and / or, the second CSI report may also carry information for indicating the second resource (or the second time domain unit).
[0268] Optionally, the terminal device may report the second information according to the instructions of the network device. For example, when instructed to report the second information through one CSI report, the terminal device may report the second information according to the first possible implementation described above; when instructed to report the second information through two CSI reports, the terminal device may report the second information according to the second possible implementation described above.
[0269] It is understood that in the embodiments of this application, the CLI measured by the terminal device can be characterized by RSRP and / or RSSI. RSRP can also be called CLI-RSRP, and RSSI can also be called CLI-RSSI. CLI-RSRP and CLI-RSSI can be understood as different CLI indicators that can be used to indicate the degree of interference. This application does not specifically limit this.
[0270] Optionally, the first CLI may include a first RSRP and / or a first RSSI; the second CLI may include a second RSRP and / or a second RSSI. This enables the indication of the level of interference between terminal devices.
[0271] The interference measurement method of this application involves a terminal device measuring a first CLI on a first resource in a first time domain unit and a second CLI on a second resource in a second time domain unit. The terminal device then reports the first and second CLIs to the network device. Since the first CLI represents inter-cell interference, and the second CLI includes both inter-cell and intra-cell interference, the network device can determine the type of interference between UEs' CLIs by combining the first and second CLIs.
[0272] For example, when the first CLI and the second CLI are close, and the first CLI is larger (e.g., greater than a certain threshold), it indicates that the second CLI mainly includes inter-cell interference, meaning that the UE CLI received by the terminal device is mainly inter-cell interference; when the second CLI is much larger than the first CLI (e.g., the difference is greater than a certain threshold), and the first CLI is smaller (e.g., less than a certain threshold), it indicates that the second CLI mainly includes intra-cell interference, meaning that the UE CLI received by the terminal device is mainly intra-cell interference.
[0273] In this way, network devices can combine the determined types of CLI interference between UEs to more accurately schedule adjacent terminal devices, thereby more accurately avoiding interference, which helps to reduce CLI between UEs and improve the communication performance of terminal devices.
[0274] The following describes how the terminal device instructs the network device to use the second information to indicate the first CLI and the second CLI.
[0275] Method 1: Instruct the first CLI and the second CLI respectively.
[0276] Optionally, the second information includes a first sub-information and a second sub-information, wherein the first sub-information is used to indicate a first CLI and the second sub-information is used to indicate a second CLI.
[0277] In this way, the network device can directly determine the first CLI based on the first sub-information; and can directly determine the second CLI based on the second sub-information. Even if the network device fails to receive the first sub-information, it can still determine the second CLI based on the second sub-information; or, even if the network device fails to receive the second sub-information, it can still determine the first CLI based on the first sub-information. This makes it highly probable that the network device can successfully obtain the first CLI and / or the second CLI.
[0278] Method 2: Report one of the CLIs, the first CLI and the second CLI, and the difference between them.
[0279] Optionally, the second information is used to indicate the first CLI and the first difference, the first difference being the difference between the second CLI and the first CLI; or, the second information is used to indicate the second CLI and the second difference, the second difference being the difference between the first CLI and the second CLI.
[0280] The first difference (or the second difference) can be the difference between the first CLI and the second CLI, or the difference between the second CLI and the first CLI.
[0281] The network device may determine the second CLI based on the first CLI and the first difference; or it may determine the first CLI based on the second CLI and the second difference.
[0282] Thus, in some scenarios, the first difference may be smaller than the second CLI, for example, the second CLI is X dBm, -45≤X<-44, and the first difference is 5.0dB, so the signaling overhead of the terminal device reporting the first difference is smaller than that of directly reporting the second CLI; similarly, the second difference may be smaller than the first CLI, so the signaling overhead of the terminal device reporting the second difference is smaller than that of directly reporting the first CLI.
[0283] It is understood that, since the second time-domain unit is an SBFD time-domain unit, and the BWP on the SBFD time-domain unit can include any of the following: DL subband, UL subband, or flexible subband. Therefore, the second resource on the second time-domain unit can include: a first frequency domain resource (DL subband) and / or a second frequency domain resource (UL subband). The first frequency domain resource on the second time-domain unit is used for downlink transmission, and the second frequency domain resource on the second time-domain unit is used for uplink transmission.
[0284] It should be noted that the embodiments of this application do not limit the second time-domain unit to only including the first frequency domain resources (DL subband) and / or the second frequency domain resources (UL subband). For example, the second time-domain unit may also include a third frequency domain resource. The third frequency domain resource on the second time-domain unit is used for guard band. That is, the DL BWP may include the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource. Or it can be understood that the bandwidth of the DL BWP (such as the number of RBs) can be equal to the sum of the bandwidth of the first frequency domain resource, the bandwidth of the second frequency domain resource, and the bandwidth of the third frequency domain resource. For the sake of simplicity, this will not be elaborated further below.
[0285] It should be understood that the first frequency domain resource can also be referred to as DL frequency domain resource, DL subband, downlink transmission available resource, resource that can be used for downlink transmission, downlink transmission available RB, downlink transmission available RE, etc.; the second frequency domain resource can also be referred to as UL frequency domain resource, UL subband, uplink transmission available resource, resource that can be used for uplink transmission, uplink transmission available RB, uplink transmission available RE, etc., and this application does not make specific limitations in this regard.
[0286] Since the second resource on the second time-domain unit includes the first frequency-domain resource and / or the second frequency-domain resource, the second CLI can be measured on some or all of the first frequency-domain resource and / or some or all of the second frequency-domain resource on the second time-domain unit. This will be explained in detail below.
[0287] First scenario: Measurement on the DL subband
[0288] Optionally, the second CLI includes a third CLI, which is measured on some or all of the resources in the first frequency domain.
[0289] In this context, the third CLI can also be understood as the second CLI. The second resource refers to part or all of the resources in the first frequency domain resource on the second time domain unit. The third CLI is measured on the second resource.
[0290] In possible mode 1, the second resource is the first frequency domain resource (or all resources of the first frequency domain resource) on the second time domain unit.
[0291] For example, referring to Figure 11(a), assuming that the second time domain unit includes time domain unit 1 to time domain unit 4, the second resource includes the first frequency domain resource (DL subband) on time domain unit 1 to time domain unit 4.
[0292] In this way, the second CLI can more accurately reflect the inter-UE interference on the DL subband. For example, referring to Figure 8, the second CLI measured by UE 2 can more accurately reflect the interference of the uplink signals sent by UE 1 and UE 3 on the downlink signals received by UE 2 in the DL subband.
[0293] In possible mode 2, the second resource is a portion of the first frequency domain resource on the second time domain unit.
[0294] For example, referring to Figure 11(b), assuming that the second time domain unit includes time domain unit 1 to time domain unit 4, the second resource includes a portion of the first frequency domain resource (DL subband) on time domain unit 1 to time domain unit 4.
[0295] This portion of the resource can be located anywhere within the first frequency domain resource. For example, the center frequency of this portion of the resource can coincide with the center frequency of the first frequency domain resource. Alternatively, the maximum frequency (or maximum point) in this portion of the resource can coincide with the maximum frequency in the first frequency domain resource. Or, the minimum frequency (or minimum point) in this portion of the resource can coincide with the minimum frequency in the first frequency domain resource.
[0296] This approach allows terminal devices to measure a second CLI with fewer resources. It also results in lower power consumption and higher efficiency in CLI measurements, and the measured interference (CLI) more accurately reflects the interference situation within the bandwidth.
[0297] Optionally, a portion of the first frequency domain resource is located closest to the UL subband within the first frequency domain resource. For example, as shown in Figure 11(b), a portion of the first frequency domain resource is located near the lower UL subband.
[0298] Thus, referring to Figure 7, since the uplink signal power leaked onto the DL subband is greater the closer it is to the UL subband, the larger the CLI (Clearance Limiting) is. Therefore, the terminal device can perform CLI measurements on a portion of the DL subband resources closer to the UL subband to achieve higher CLI measurement accuracy.
[0299] The second scenario: Measurement on the UL sub-band.
[0300] Optionally, the second CLI includes a fourth CLI, which is measured on some or all of the resources in the second frequency domain.
[0301] In this context, the fourth CLI can also be understood as the second CLI. The second resource refers to part or all of the second frequency domain resource on the second time-domain unit. The fourth CLI is measured on the second resource.
[0302] It is understandable that, in addition to the inter-UE CLI caused by uplink transmission to downlink reception, the transmitted downlink signal may also cause inter-UE CLI to the terminal device's uplink signal transmission. For example, referring to Figure 8, in addition to the interference of the uplink signals transmitted by UE 1 and UE 3 to UE 2's downlink signal reception in the DL subband, for UE 1, the downlink signal received by UE 2 may also interfere with UE 1's uplink signal transmission, and this interference can be understood as intra-cell interference; for UE 3, the downlink signal received by UE 2 may also interfere with UE 3's uplink signal transmission, and this interference can be understood as inter-cell interference.
[0303] Therefore, in addition to performing CLI measurements on the first frequency domain resource (DL subband) used for downlink transmission, the terminal device can also perform CLI measurements on the second frequency domain resource (UL subband) used for uplink transmission.
[0304] In possible mode 3, the second resource is the second frequency domain resource on the second time domain unit (or all resources of the second frequency domain resource).
[0305] For example, referring to Figure 12(a), assuming that the second time domain unit includes time domain unit 1 to time domain unit 4, the second resource includes the second frequency domain resource (UL subband) on time domain unit 1 to time domain unit 4.
[0306] In this way, the second CLI can more accurately reflect the inter-UE interference on the UL subband.
[0307] In possible mode 4, the second resource is a portion of the second frequency domain resource on the second time domain unit.
[0308] For example, referring to Figure 12(b), assuming that the second time domain unit includes time domain unit 1 to time domain unit 4, the second resource includes a portion of the second frequency domain resource (UL subband) on time domain unit 1 to time domain unit 4.
[0309] This portion of the resource can be located anywhere within the second frequency domain resource. For example, the center frequency of this portion of the resource can coincide with the center frequency of the second frequency domain resource. Alternatively, the maximum frequency (or maximum point) in this portion of the resource can coincide with the maximum frequency in the second frequency domain resource. Or, the minimum frequency (or minimum point) in this portion of the resource can coincide with the minimum frequency in the second frequency domain resource.
[0310] This approach allows terminal devices to measure a second CLI with fewer resources. It also results in lower power consumption and higher efficiency in CLI measurements, and the measured interference (CLI) more accurately reflects the interference situation within the bandwidth.
[0311] Optionally, a portion of the second frequency domain resource is located in the position closest to the DL subband within the second frequency domain resource. For example, as shown in Figure 12(b), a portion of the second frequency domain resource is located in the UL subband near the DL subband.
[0312] Thus, similar to Figure 7, the closer to the DL subband in the UL subband, the greater the downlink signal power leaked in the UL subband, and therefore the larger the CLI. Therefore, terminal devices can perform CLI measurements on frequency domain resources in the UL subband that are close to the DL subband, resulting in higher accuracy of CLI measurements.
[0313] The third scenario: Measurements are taken separately on the DL sub-band and the UL sub-band.
[0314] Optionally, the second CLI includes a third CLI and a fourth CLI, wherein the third CLI is measured on some or all of the resources in the first frequency domain resources, and the fourth CLI is measured on some or all of the resources in the second frequency domain resources.
[0315] In this case, the second resource includes: some or all of the resources in the first frequency domain resource on the second time domain unit and some or all of the resources in the second frequency domain resource on the second time domain unit.
[0316] It should be noted that for the same terminal device, the terminal device may not be able to simultaneously perform: measuring a third CLI on some or all resources in the first frequency domain resource (DL subband), and measuring a fourth CLI on some or all resources in the second frequency domain resource (UL subband). Therefore, the second resource may include: some or all resources in the first frequency domain resource within the first partial time domain unit, and some or all resources in the second frequency domain resource within the second partial time domain unit; both the first and second partial time domain units belong to the second time domain unit. Furthermore, the first partial time domain unit may include one or more SBFD time domain units; the second partial time domain unit may include one or more SBFD time domain units. The first partial time domain unit can be understood as the second time domain unit within the second time domain unit whose frequency domain resource used for CLI measurement is located within the DL subband. The second partial time domain unit can be understood as the second time domain unit within the second time domain unit whose frequency domain resource used for CLI measurement is located within the UL subband.
[0317] In possible mode 5, the second resource includes: the first frequency domain resource in the first part of the time domain unit and the second frequency domain resource in the second part of the time domain unit.
[0318] For example, referring to Figure 13(a), assuming the second time-domain unit includes time-domain units 1 to 4, the first part of the time-domain unit includes time-domain unit 1 and time-domain unit 3, and the first frequency domain resource is a DL subband; then the second resource includes the DL subbands on time-domain units 1 and 3. The third CLI is measured on the DL subbands on time-domain units 1 and 3.
[0319] The second part of the time-domain unit includes time-domain unit 2 and time-domain unit 4, and the second frequency domain resource is the UL sub-band; therefore, the second resource also includes the UL sub-band on time-domain unit 2 and time-domain unit 4. The fourth CLI is measured on the UL sub-band on time-domain unit 2 and time-domain unit 4.
[0320] In this way, the third CLI can more accurately reflect inter-UE interference on the DL subband. The fourth CLI can more accurately reflect inter-UE interference on the UL subband.
[0321] In possible mode 6, the second resource includes: the first frequency domain resource in the first part of the time domain unit, and a portion of the second frequency domain resource in the second part of the time domain unit.
[0322] For example, referring to Figure 13(b), assuming the second time-domain unit includes time-domain units 1 to 4, the first part of the time-domain unit includes time-domain unit 1 and time-domain unit 3, and the first frequency domain resource is a DL subband; then the second resource includes the DL subbands on time-domain units 1 and 3. The third CLI is measured on the DL subbands on time-domain units 1 and 3.
[0323] The second part of the time-domain unit includes time-domain unit 2 and time-domain unit 4, and the second frequency-domain resource is the UL sub-band; therefore, the second resource also includes a portion of the second frequency-domain resource on time-domain unit 2 and time-domain unit 4. The fourth CLI is measured on this portion of the resource on time-domain unit 2 and time-domain unit 4.
[0324] It should be understood that the location of some resources in the second frequency domain resources is similar to that in possible mode 4, and can be referred to the description above, which will not be repeated here.
[0325] This method enables terminal devices to measure the fourth CLI with fewer resources, resulting in lower power consumption and higher efficiency in CLI measurements.
[0326] In possible mode 7, the second resource includes: a portion of the first frequency domain resource in the first part of the time domain unit, and the second frequency domain resource in the second part of the time domain unit.
[0327] For example, referring to Figure 13(c), assume that the second time-domain unit includes time-domain units 1 to 4, the first partial time-domain unit includes time-domain unit 1 and time-domain unit 3; the second resource includes a portion of the first frequency domain resource in time-domain units 1 and 3. The third CLI is measured on a portion of the first frequency domain resource in time-domain units 1 and 3.
[0328] The second part of the time-domain units includes time-domain unit 2 and time-domain unit 4; the second resource also includes the second frequency-domain resources on time-domain units 2 and 4. The fourth CLI is measured on the second frequency-domain resources on time-domain units 2 and 4.
[0329] It should be understood that the location of some resources in the first frequency domain resource is similar to that in the possible implementation in mode 2, and can be referred to the description above, which will not be repeated here.
[0330] In possible mode 8, the second resource includes: a portion of the first frequency domain resource in the first part of the time domain unit, and a portion of the second frequency domain resource in the second part of the time domain unit.
[0331] It should be understood that in this implementation, the measurement of the third CLI is similar to that of the third CLI in possible mode 7; the measurement of the fourth CLI is similar to that of the fourth CLI in possible mode 6, as can be referred to the description above, and will not be repeated here.
[0332] It should be noted that in the third scenario, the third CLI, the fourth CLI, and the first CLI can be reported through the same CSI report or through different CSI reports, similar to the first and second possible implementation methods described above. Please refer to the description above, and it will not be repeated here.
[0333] Furthermore, the third CLI, fourth CLI, and first CLI can be reported directly, similar to Method 1 above. In Method 1, the second sub-information can include third sub-information indicating the third CLI, and the second sub-information also includes fourth sub-information indicating the fourth CLI. Alternatively, similar to Method 2 above, the terminal device can report a portion of the third CLI, fourth CLI, and first CLI, as well as the difference between the portion of CLI and the remaining CLI, through the second information. The remaining CLI can be determined by the portion of CLI and the difference. The portion of CLI can be one or two of the third CLI, fourth CLI, and first CLI. The specific implementation is similar to Method 2 above, and can be referred to the description above, which will not be repeated here.
[0334] Fourth scenario: Measuring together on both the DL sub-band and the UL sub-band.
[0335] Optionally, the second CLI is measured on some or all of the resources of the first frequency domain resource and some or all of the resources of the second frequency domain resource.
[0336] In this case, the second resource may include part or all of the resources of the first frequency domain resource on the second time domain unit, and part or all of the resources of the second frequency domain resource on the second time domain unit.
[0337] In possible mode 9, the second resource includes the first frequency domain resource on the second time domain unit, and a portion of the second frequency domain resource on the second time domain unit.
[0338] For example, referring to Figure 14(a), assume that the second time-domain unit includes time-domain units 1 to 4, and the second resource includes a portion of the first frequency domain resource and the second frequency domain resource in time-domain units 1 to 4. The second CLI is measured on a portion of the first frequency domain resource and the second frequency domain resource in time-domain units 1 to 4.
[0339] In possible mode 10, the second resource includes a portion of the first frequency domain resource in the second time domain unit and the second frequency domain resource in the second time domain unit.
[0340] For example, referring to Figure 14(b), assume that the second time-domain unit includes time-domain units 1 to 4, and the second resource includes a portion of the first frequency-domain resource and a second frequency-domain resource in time-domain units 1 to 4. The second CLI is measured on the portion of the first frequency-domain resource and the second frequency-domain resource in time-domain units 1 to 4.
[0341] In possible mode 11, the second resource includes a portion of the first frequency domain resource in the second time domain unit and a portion of the second frequency domain resource in the second time domain unit.
[0342] For example, referring to (c) in FIG14, it is assumed that the second time-domain unit includes time-domain units 1 to 4, and the second resource includes a portion of the first frequency-domain resource and a portion of the second frequency-domain resource in time-domain units 1 to 4. The second CLI is measured on the portion of the first frequency-domain resource and the portion of the second frequency-domain resource in time-domain units 1 to 4.
[0343] In possible mode 12, the second resource includes the first frequency domain resource in the second time domain unit and the second frequency domain resource in the second time domain unit.
[0344] For example, referring to (d) in Figure 14, assume that the second time-domain unit includes time-domain units 1 to 4, and the second resource includes the first frequency domain resource and the second frequency domain resource in time-domain units 1 to 4. The second CLI is measured on the first frequency domain resource and the second frequency domain resource in time-domain units 1 to 4.
[0345] It should be noted that Figures 10 to 14 shown above are only examples. In actual application scenarios, the time domain units included in the second time domain unit can also be time domain units with other index values, and the time domain units in the second time domain unit can be continuous or non-continuous. This application does not make any specific limitations on this.
[0346] It is understandable that, considering the third scenario above, when the second CLI includes both the third and fourth CLIs, since the fourth CLI is measured on some or all of the resources in the second frequency domain, the center frequency and bandwidth of some or all of the resources in the second frequency domain differ from those of the first frequency domain resources. Therefore, the terminal device needs to switch the filtering bandwidth between downlink transmission (or signal reception) on the first frequency domain resources and CLI measurement on some or all of the resources in the second frequency domain. This will be explained in detail below.
[0347] As an optional embodiment, method 900 further includes: the terminal device sending third information to the network device, the third information being used to indicate the first handover time and / or the number of handovers; correspondingly, the network device receiving the third information from the terminal device.
[0348] The first switching time is the time required to switch between downlink transmission in the first frequency domain resource and CLI measurement in the second frequency domain resource; the number of switching times is the number of times switching between downlink transmission in the first frequency domain resource and CLI measurement in the second frequency domain resource in multiple consecutive second time domain units; the first frequency domain resource is the resource used for downlink transmission in the second time domain unit, and the second frequency domain resource is the resource used for uplink transmission in the second time domain unit.
[0349] It should be understood that both the first handover time and the number of handovers refer to handovers occurring between different time domain units; handovers are not required within the same time domain unit. For example, the first handover time is the time required to switch between downlink transmission on a first frequency domain resource in a full-duplex time domain unit and CLI measurement on a second frequency domain resource in another full-duplex time domain unit. The number of handovers is the number of times, across multiple consecutive second time domain units, the handover occurs between downlink transmission on a first frequency domain resource in a full-duplex time domain unit and CLI measurement on a second frequency domain resource in another full-duplex time domain unit.
[0350] It can be understood that downlink transmission on the first frequency domain resource can also be understood as: the terminal device receiving downlink signals on the first frequency domain resource, and downlink transmission on the first frequency domain resource can also include CLI measurements on the first frequency domain resource. Handover can be understood as switching the filtering bandwidth of the downlink filter and / or switching the center frequency, etc. Although the second frequency domain resource is used for uplink transmission, since the interference on the second frequency domain resource is caused by the downlink transmission of other terminal devices, that is, by downlink signal leakage onto the second frequency domain resource, CLI measurements on the second frequency domain resource also involve downlink reception. CLI measurements on the second frequency domain resource can be understood as performing CLI measurements on all or part of the second frequency domain resource.
[0351] The first possible method, the third information is used to indicate the first switching time.
[0352] It should be understood that the first handover time can be represented by one or more time-domain units, such as one or more symbols or one or more time slots. Furthermore, the first handover time can be understood as a UE capability. Different terminal devices may support different first handover times. When third information is used to indicate the first handover time, the third information can also be carried in the UE capability message.
[0353] Furthermore, the first handover time may include handover time 1 and / or handover time 2. Handover time 1 is the time required to switch from downlink transmission in the first frequency domain resource to CLI measurement in the second frequency domain resource; handover time 2 is the time required to switch from CLI measurement in the second frequency domain resource to downlink transmission in the first frequency domain resource.
[0354] It is understood that handover time 1 and handover time 2 may be the same or different, and when handover time 1 and handover time 2 are the same, the first handover time may also include one of handover time 1 or handover time 2. Furthermore, the network device can determine handover time 1 and handover time 2 based on this single handover time.
[0355] For switching time 1, the shorter the switching time 1, the faster the downlink filtering bandwidth of the terminal device can switch from the first frequency domain resource to the second frequency domain resource. Therefore, the time interval between the terminal device performing CLI measurement (or downlink transmission) on the first frequency domain resource and performing CLI measurement on the second frequency domain resource can be smaller.
[0356] For example, suppose the switching time 1 is 2 time domain units. Then, as shown in Figure 15, time domain units 1 to 5 can be 5 consecutive time domain units, and these 5 time domain units can be understood as SBFD time domain units. Assuming the terminal device performs downlink transmission on the first frequency domain resource of time domain unit 1, for example, the terminal device can receive downlink signals on the first frequency domain resource of time domain unit 1, and can also perform CLI measurements on time domain unit 1, then when the switching time 1 is 2 time domain units, the terminal device can perform CLI measurements on the second frequency domain resource of time domain unit 3, so that the terminal device can successfully switch the filter bandwidth.
[0357] Similar to switching time 1, a shorter switching time 2 means that the downlink filtering bandwidth of the terminal device can switch from the second frequency domain resource to the first frequency domain resource more quickly. Therefore, the time interval between CLI measurements performed by the terminal device on the second frequency domain resource and CLI measurements (or downlink transmission) performed on the first frequency domain resource can be smaller.
[0358] For example, assume that the switching time 2 is two time-domain units. Then, referring to Figure 15, assume that the terminal device performs CLI measurements on the second frequency domain resource of time-domain unit 3; since the switching time 2 is two time-domain units, the terminal device performs downlink transmission on the first frequency domain resource of time-domain unit 5. For example, the terminal device can receive downlink signals on the first frequency domain resource of time-domain unit 5, and can also perform CLI measurements on time-domain unit 5, so that the terminal device can successfully switch the filter bandwidth.
[0359] Therefore, through the first handover time, the terminal device and the network device can determine the resources actually used to measure the third CLI and the resources actually used to measure the fourth CLI during CLI measurement. For example, referring to Figure 15, when both handover time 1 and handover time 2 are two time domain units, the second resource may include the first frequency domain resources on time domain unit 1 and time domain unit 5, and the terminal device can measure the third CLI on the first frequency domain resources on time domain unit 1 and time domain unit 5; the second resource may include the second frequency domain resources on time domain unit 3, and the terminal device can measure the fourth CLI on the second frequency domain resources on time domain unit 3.
[0360] The second possible method, the third piece of information, is used to indicate the number of switching operations.
[0361] The number of handovers is defined as the number of times a downlink transmission is performed on a first frequency domain resource and a CLI measurement is performed on a second frequency domain resource across multiple consecutive second time domain units.
[0362] Here, a series of consecutive second time-domain units can be understood as a series of consecutive SBFD time-domain units. For example, time-domain units 1 to 5 are shown in Figure 15.
[0363] By varying the number of handovers, terminal devices and network devices can determine the second resources used to measure the third CLI and the fourth CLI in multiple consecutive second time-domain units.
[0364] For example, still referring to Figure 15, if the terminal device switches twice via the third information in consecutive time domain units 1 to 5, then the terminal device performs CLI measurements three times.
[0365] In one scenario, the terminal device can perform two CLI measurements on the first frequency domain resources, specifically on the first frequency domain resources of two second time domain units (time domain unit 1 and time domain unit 5 in Figure 15). Between these two CLI measurements, a CLI measurement is performed on the second frequency domain resources of one second time domain unit (time domain unit 3 in Figure 15) between the two second time domain units. This is similar to the situation shown in Figure 15.
[0366] In another scenario, the terminal device can also perform two CLI measurements on the second frequency domain resources, that is, CLI measurements on the second frequency domain resources of two second time domain units. Between these two CLI measurements, a CLI measurement is performed on the first frequency domain resources, that is, a CLI measurement is performed on the first frequency domain resources of one second time domain unit between the two second time domain units. For example, still referring to Figure 15, the terminal device can perform CLI measurements on the second frequency domain resources of time domain units 1 and 5 to determine the fourth CLI; and can perform CLI measurements on the first frequency domain resources of time domain unit 3 to determine the third CLI.
[0367] To enable terminal devices and network devices to accurately determine the resources within the second resource used for measuring the third CLI and the resources used for measuring the fourth CLI, a protocol can be predefined, or the terminal device can report it, or the network device can configure it via signaling. Information 1 indicates that, across multiple consecutive second time-domain units, the terminal device should perform CLI measurements first (or preferentially) on the first frequency-domain resource. For example, if Information 1 indicates that the terminal device should preferentially perform CLI measurements on the first frequency-domain resource across multiple consecutive second time-domain units, then, similar to the situation shown in Figure 15, the terminal device performs CLI measurements on the first frequency-domain resource in time-domain unit 1 from time-domain unit 1 to time-domain unit 5. Alternatively, a protocol can be predefined, or the terminal device can report it, or the network device can configure it via signaling. Information 2 indicates that, across multiple consecutive second time-domain units, the terminal device should perform CLI measurements first (or preferentially) on the second frequency-domain resource. CLI measurements can be performed on the second frequency domain resources of time domain units 1 to 5 as shown in Figure 15, and CLI measurements can also be performed on the first frequency domain resources of time domain unit 3.
[0368] It should be noted that Figure 15 is merely an example; in actual applications, the number of consecutive second time-domain units can be more or less. Furthermore, the consecutive second time-domain units shown in Figure 15 can be understood as consecutive time-domain units within a group or a single measurement resource. For example, if the time-domain units shown in Figure 15 are symbols, then consecutive symbols 1 to 5 can represent consecutive second time-domain units within a single time slot. The second resource can include measurement resources (or multiple measurement resources) across multiple time slots, and each time slot (within each time slot's measurement resources) can include consecutive second time-domain units similar to symbols 1 to 5. This application does not impose specific limitations in this regard.
[0369] The third possible method, the third piece of information, is used to indicate the first switching time and the number of switching operations.
[0370] The third information may include information indicating the first switching time and information indicating the number of switching operations.
[0371] It is understandable that the third possible approach can be understood as a combination of the first and second possible approaches. Similar to the first and second possible approaches, please refer to the description above, which will not be repeated here.
[0372] In this approach, terminal devices and network devices are able to more accurately identify the second resource.
[0373] In addition to the second resource, the terminal device also needs to measure the first CLI on the first resource in the first time domain unit. The bandwidth of the first resource is different from the bandwidth of the first frequency domain resource, and the center frequency of the first resource is different from the center frequency of the first frequency domain resource; furthermore, the bandwidth of the first resource is different from the bandwidth of the second frequency domain resource, and the center frequency of the first resource is different from the center frequency of the second frequency domain resource. Therefore, the terminal device can also report one or more of the second handover time, third handover time, fourth handover time, or fifth handover time.
[0374] The second switching time is the time required to switch between downlink transmission on the DL BWP of the DL time domain unit and downlink transmission on the first frequency domain resource.
[0375] The DL time-domain unit belongs to the first time-domain unit. The DL time-domain unit can be understood as the first time-domain unit used for downlink transmission.
[0376] That is, when the first time domain unit includes the DL time domain unit, the filtering bandwidth of the downlink filtering of the terminal device may switch between the DL BWP and the first frequency domain resource.
[0377] The second switching time may include switching time 3 and / or switching time 4; wherein, switching time 3 is the time for switching from downlink transmission on the DL BWP of the DL time domain unit to downlink transmission on the first frequency domain resource; and switching time 4 is the time for switching from downlink transmission on the first frequency domain resource to downlink transmission on the DL BWP of the DL time domain unit. Switching time 3 and switching time 4 may be the same or different.
[0378] Downlink transmission on the DL BWP of the DL time domain unit can include receiving downlink signals on the DL BWP of the DL time domain unit, and can also include performing CLI measurements on the DL BWP of the DL time domain unit.
[0379] For example, referring to Figure 15, time domain unit 0 can be understood as the DL time domain unit in the first time domain unit, such as the DL symbol, etc., and the DL BWP of time domain unit 0 can be understood as the sum of the DL subband and the UL subband. The first resource may include the DL BWP of time domain unit 0. By performing CLI measurement on the DL BWP of time domain unit 0, the terminal device can determine the first CLI. After performing CLI measurement in time domain unit 0, the downlink filtering bandwidth of the terminal device needs to be switched, such as switching to downlink transmission on the first frequency domain resource. The filtering bandwidth can be switched from the DL BWP to the DL subband. Assuming that the time for switching from downlink transmission on the DL BWP of the DL time domain unit to downlink transmission on the first frequency domain resource is one frequency domain unit, the terminal device can perform downlink transmission (including CLI measurement) on the first frequency domain resource of time domain unit 1.
[0380] The third switching time is the time required to switch between downlink transmission on the DL BWP of the DL time domain unit and CLI measurement on the second frequency domain resource.
[0381] That is, when the first time domain unit includes the DL time domain unit, the filtering bandwidth of the downlink filtering of the terminal device may switch between the DL BWP and the second frequency domain resources.
[0382] Furthermore, the third switching time may include switching time 5 and / or switching time 6; wherein, switching time 5 is the time for switching from downlink transmission on the DL BWP of the DL time domain unit to CLI measurement on the second frequency domain resource; and switching time 6 is the time for switching from CLI measurement on the second frequency domain resource to downlink transmission on the DL BWP of the DL time domain unit. Switching time 5 and switching time 6 may be the same or different.
[0383] Downlink transmission on the DL BWP of the DL time domain unit can include receiving downlink signals on the DL BWP of the DL time domain unit, and can also include performing CLI measurements on the DL BWP of the DL time domain unit.
[0384] For example, referring to Figure 15, time domain unit 0 can be understood as the DL time domain unit in the first time domain unit. The first resource may include the DL BWP of time domain unit 0. After CLI measurement is performed in time domain unit 0, the downlink filtering bandwidth of the terminal device needs to be switched, such as switching to CLI measurement on the second frequency domain resource. The filtering bandwidth can be switched from DL BWP to UL subband. Assuming that the time for switching from downlink transmission on the DL BWP of the DL time domain unit to CLI measurement on the second frequency domain resource is one frequency domain unit, the terminal device can perform CLI measurement on the second frequency domain resource of time domain unit 1.
[0385] The fourth switching time is the time required to switch between performing CLI measurements on the UL BWP of the UL time domain unit and performing downlink transmission on the first frequency domain resource.
[0386] The UL time domain unit belongs to the first time domain unit. The UL time domain unit can be understood as the first time domain unit used for uplink transmission.
[0387] In other words, when the first time-domain unit includes the UL time-domain unit, similar to the CLI measurement performed on the second frequency domain resource mentioned above, the terminal device also needs to perform downlink filtering when performing CLI measurements on the UL time-domain unit. That is, CLI on the UL BWP of the UL time-domain unit can be caused by downlink signal leakage onto the UL BWP. Therefore, the terminal device performs downlink filtering when performing CLI measurements on the UL BWP of the UL time-domain unit. Thus, when the first time-domain unit includes the UL time-domain unit, the filtering bandwidth of the terminal device's downlink filtering may switch between the UL BWP and the first frequency domain resource. The resource used for CLI measurements on the UL BWP of the UL time-domain unit must be within the bandwidth range of the DL BWP in the frequency domain.
[0388] Furthermore, the fourth switching time may include switching time 7 and / or switching time 8; wherein, switching time 7 is the time for switching from CLI measurement on the UL BWP of the UL time domain unit to downlink transmission on the first frequency domain resource; and switching time 8 is the time for switching from downlink transmission on the first frequency domain resource to CLI measurement on the UL BWP of the UL time domain unit. Switching time 7 and switching time 8 may be the same or different.
[0389] For example, assuming the first time-domain unit includes a UL time-domain unit, referring to Figure 15, time-domain unit 6 is a UL time-domain unit, such as a UL OFDM symbol. After the terminal device performs CLI measurement on the first frequency domain resource in time-domain unit 5, the downlink filtering bandwidth of the terminal device needs to be switched to perform CLI measurement on the UL BWP. The filtering bandwidth can be switched from the DL subband to the UL BWP. Assuming the time for switching from downlink transmission on the first frequency domain resource to CLI measurement on the UL BWP of the UL time-domain unit is one time-domain unit (e.g., a symbol), the terminal device can perform CLI measurement on the UL BWP of time-domain unit 6. That is, the first resource can include the UL BWP of time-domain unit 6, and by performing CLI measurement on the UL BWP of time-domain unit 6, the terminal device can determine the first CLI.
[0390] The fifth switching time is the time required to switch between performing CLI measurements on the UL BWP of the UL time domain unit and performing CLI measurements on the second frequency domain resource.
[0391] That is, when the first time domain unit includes the UL time domain unit, the filtering bandwidth of the downlink filtering of the terminal device may switch between the UL BWP and the second frequency domain resources.
[0392] Furthermore, the fifth switching time may include switching time 9 and / or switching time 10; wherein, switching time 9 is the time for switching from CLI measurement on the UL BWP of the UL time domain unit to CLI measurement on the second frequency domain resource; and switching time 10 is the time for switching from CLI measurement on the second frequency domain resource to CLI measurement on the UL BWP of the UL time domain unit. Switching time 9 and switching time 10 may be the same or different.
[0393] For example, assuming the first time domain unit includes a UL time domain unit, referring to Figure 15, time domain unit 6 is a UL time domain unit, such as the UL symbol, etc. The UL BWP of time domain unit 6 can be understood as the sum of the DL subband and the UL subband. Assuming that after the terminal device performs CLI measurement on the second frequency domain resource in time domain unit 5, the downlink filtering bandwidth of the terminal device needs to be switched to perform CLI measurement on the UL BWP. The filtering bandwidth can be switched from the DL subband to the UL BWP. Assuming that the time for switching from downlink transmission on the first frequency domain resource to CLI measurement on the UL BWP of the UL time domain unit is one frequency domain unit, the terminal device can perform CLI measurement on the UL BWP of time domain unit 6.
[0394] It is understood that one or more of the first, second, third, fourth, or fifth handover times shown above can be handover times among multiple handover times. These multiple handover times can be predefined by the protocol or configured by the network device through signaling. That is, one or more of the first, second, third, fourth, or fifth handover times reported by the terminal device can be determined from multiple handover times.
[0395] Combining the various handover times and handover counts shown above, the actual resources measured by the terminal device during CLI measurements may vary depending on the UE capabilities of the terminal device.
[0396] In one scenario, the first and / or second resources configured by the network device can be based on one or more of the following: a first handover time, a second handover time, a third handover time, a fourth handover time, a fifth handover time, or the number of handovers. In this case, the first and second resources configured by the network device are the resources actually measured by the terminal device during CLI measurements.
[0397] For example, referring to Figure 15, the first resource configured by the network device may include the BWP on time domain unit 0; the second resource may include the first frequency domain resource on time domain unit 1 and time domain unit 5, and the second frequency domain resource on time domain unit 3.
[0398] In another scenario, the first and / or second resources configured by the network device can be a resource range, which is the range of resources actually measured by the terminal device when performing CLI measurements. Furthermore, the resources actually measured by the terminal device when performing CLI measurements are determined based on one or more of the following: a first handover time, a second handover time, a third handover time, a fourth handover time, a fifth handover time, or the number of handovers.
[0399] Furthermore, in this case, using the second resource to measure the second CLI on the second time domain unit does not mean that the terminal device performs CLI measurements on all resources in the second resource. Similarly, using the first resource to measure the first CLI may not mean that the terminal device performs CLI measurements on all resources in the first resource. Instead, both the terminal device and the network device can determine the resource actually measured when performing CLI measurements in the first and second resources based on one or more of the first handover time, second handover time, third handover time, fourth handover time, fifth handover time, or the number of handovers.
[0400] For example, referring to Figure 15, taking the determination of the resources actually measured by the terminal device when performing CLI measurements in the second resource as an example, the second resource configured by the network device includes the first frequency domain resource and the second frequency domain resource in time domain units 1 to 5. Assume the first handover time reported by the terminal device is 2 time domain units, that is, the handover time between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource is 2 time domain units. Assume that in multiple consecutive second time domain units, the terminal device prioritizes measuring CLI on the first frequency domain resource. Then, both the terminal device and the network device can determine that the resources for the terminal device to measure the third CLI include: the first frequency domain resources on time domain units 1 and 5; and the resources for the terminal device to measure the fourth CLI include: the second frequency domain resource on time domain unit 3.
[0401] It should be noted that the embodiments describing the switching time and number of switching are based on the example where the terminal device measures the third CLI on the first frequency domain resource and the fourth CLI on the second frequency domain resource. In actual application scenarios, the terminal device may also measure the third CLI on a portion of the first frequency domain resource and the fourth CLI on a portion of the second frequency domain resource. Therefore, when the terminal device switches the filtering bandwidth, the switched filtering bandwidth may be different. For example, when the terminal device measures the fourth CLI on a portion of the second frequency domain resource, the switching from downlink transmission on the first frequency domain resource to CLI measurement on the second frequency domain resource can be understood as the downlink filtering bandwidth switching from the first frequency domain resource to a portion of the second frequency domain resource. This application does not specifically limit this.
[0402] Based on the above embodiments, the resources of the first CLI and the second CLI can be determined in the following manner.
[0403] The first method, the first CLI, and / or the second CLI are measured on measurement resources in multiple time slots.
[0404] In this embodiment, measurement resources in multiple time slots can also be understood as a periodic measurement resource. For example, if the index ID (identify) of this measurement resource is 1, it is a resource in multiple time slots, meaning that the periodic measurement resource includes measurement resources in multiple time slots. Measurement resources in multiple time slots can also be understood as multiple measurement resources. For example, if one measurement resource has an index ID of 2 and another has an index ID of 3, they are resources in multiple time slots, meaning multiple measurement resources in multiple time slots. When multiple measurement resources include multiple measurement resources corresponding to multiple indices (or index IDs), the measurement resource corresponding to each index can be a periodic measurement resource or a non-periodic measurement resource. For simplicity, this will not be elaborated further below.
[0405] As a first optional embodiment, the first information is used to configure measurement resources in multiple time slots, including a first resource and a second resource. Then, the first CLI is measured on the first resource among the measurement resources in the multiple time slots; the second CLI is measured on the second resource among the measurement resources in the multiple time slots.
[0406] In this embodiment, the measurement resources in each of the multiple time slots can be replaced with the measurement resources in a set of time-domain units (e.g., a time slot), where a set of time-domain units includes one or more time-domain units. For example, assuming the time-domain units (e.g., the first and second time-domain units) mentioned above are symbols, then a set of time-domain units can be a time slot. In this embodiment, the example of one time-domain unit being one symbol and one set of time-domain units being one time slot is used for description. A symbol refers to an OFDM symbol.
[0407] That is, a time slot includes multiple symbols, which may include non-SBFD symbols (first time domain unit) and SBFD symbols (second time domain unit). The first information can configure measurement resources in the multiple time slots, and measurement resources exist in each of the multiple time slots. The first resource includes the resources on the non-SBFD symbols in the multiple time slots; the second resource includes the resources on the SBFD symbols in the multiple time slots.
[0408] Taking one time slot in a multi-slot network as an example, the measurement resources in that time slot can be as shown in Figure 16. Symbols 3 and 4 can belong to a first time-domain unit (non-SBFD symbols); symbols 5 to 8 can belong to a second time-domain unit (SBFD symbols). The second resource can, for example, include some or all of the DL subband (or UL subband) resources on symbols 5 to 8. For the other time slots in the multi-slot network, the measurement resources in each time slot can be similar to those shown in Figure 16. Alternatively, the measurement resources in the other time slots in the multi-slot network can also be different from those shown in Figure 16. That is, the measurement resources in each time slot of the multi-slot network can be the same, partially the same, or completely different.
[0409] It is understood that multiple time slots can be periodic or non-periodic. Multiple time slots can be consecutive or discontinuous. For example, if the first information configures a periodic resource for CLI measurements (e.g., ID=4), then the first resource is the CLI resource in the first time domain unit within that configured periodic CLI resource. The second resource is the CLI resource in the second time domain unit within that configured periodic CLI resource. In the frequency domain, the bandwidth of the first and second resources can be the same or different.
[0410] Taking multiple time slots that are periodic as an example, the index of these multiple time slots can be equal to: i + a × j; where i represents the index of the first time slot (the starting time slot) in the multiple time slots; j represents the difference between the indices of two adjacent time slots in the multiple time slots, and j can be configured by the network device; a is an integer starting from 0, and different values of a can determine different time slots, and the range of values of a can also be configured by the network device; i, a, and j are integers greater than or equal to 0. This can be understood as configuring the period (i.e., the value of j, j>=1), the starting position (i.e., the value of i), etc., of the CLI measurement resources.
[0411] Assuming j is 2, some time slots among the multiple time slots can be as shown in Figure 17. These multiple time slots can include time slot i and time slot i+2. Both time slot i and time slot i+2 include measurement resources.
[0412] Based on the above embodiments, measurement resources in multiple time slots constitute a first resource and a second resource. The first CLI is measured on the first resource in the multiple time slots. The second CLI is measured on the second resource in the multiple time slots. The first CLI and the second CLI can be determined, for example, in the following manner.
[0413] It is understandable that, for the measurement resources in each of the multiple time slots, the terminal device can perform CLI measurements on the first and second resources of each measurement resource, respectively, to obtain a first value and a second value. The first value can be understood as the CLI (which may be RSRP and / or RSSI) measured on the first resource in each measurement resource, and the second value is the CLI (which may be RSRP and / or RSSI) measured on the second resource in each measurement resource. In this way, after the measurement resources in each of the multiple time slots have been measured, the terminal device can determine multiple first values and multiple second values.
[0414] For example, referring to Figure 17, the terminal device can perform CLI measurements on a first resource in time slot i to determine a first value; it can perform CLI measurements on a second resource in time slot i to obtain a second value; the terminal device can perform CLI measurements on a first resource in time slot i+2 to determine another first value; it can perform CLI measurements on a second resource in time slot i+2 to obtain another second value. And so on, the terminal device can determine multiple first values and multiple second values. That is, both the first and second values are values obtained by measurement on a measurement resource within a time slot.
[0415] The first CLI can be determined based on multiple first values; the second CLI can be determined based on multiple second values.
[0416] For example, the first CLI may include one or more of the following: multiple first values, the average of multiple first values, a weighted average of multiple first values (the weighting coefficient is not limited and may be configured by the network device), the maximum value of multiple first values, or the minimum value of multiple first values, etc. The second CLI may include one or more of the following: multiple second values, the average of multiple second values, a weighted average of multiple second values (the weighting coefficient is not limited and may be configured by the network device), the maximum value of multiple second values, or the minimum value of multiple second values, etc.
[0417] It can be understood that the first CLI can be the average of the CLIs measured on the first resource among the measurement resources in multiple time slots; the second CLI can be the average of the CLIs measured on the second resource among the measurement resources in multiple time slots. The average value can also include a weighted average value.
[0418] It should be noted that when CLI includes RSRP, multiple first values include multiple RSRP 1, and multiple second values also include multiple RSRP 2. When CLI includes RSSI, multiple first values include multiple RSSI 1, and multiple second values also include multiple RSSI 2.
[0419] Multiple first values and multiple second values can be determined in the following way.
[0420] Taking one of multiple first values as an example, let's call it first value β. First value β is the CLI measured on a first resource within a measurement resource in a time slot. For ease of description, this first resource is referred to as first resource β. Then, first value β is the CLI obtained by the terminal device performing CLI measurement on first resource β.
[0421] The first value β is the average of multiple measurements obtained by the terminal device in the first resource β. For ease of description, these multiple measurements are referred to as multiple measurement values α (such as RSRP and / or RSSI). That is, the first value β is the average of multiple measurement values α, which are measured on the first resource β, which belongs to a measurement resource in a time slot.
[0422] It should be understood that multiple measurement values α may include: measurement values measured on each RE in the first resource β (such as measured RSRP and / or RSSI), measurement values measured on each symbol in the first resource β, measurement values measured on each RB in the first resource β, or measurement values measured on each RB of each symbol in the first resource β. That is, each measurement value (such as measurement value α, first measurement value to sixth measurement value, etc.) in the embodiments of this application may be a value measured at any resource granularity such as one or more: RE, RB, symbol, or each symbol and each RB. The embodiments of this application do not specifically limit the resource granularity at which each measurement value is measured by the terminal device.
[0423] Alternatively, the first value β can also be understood as the linear average of the total power measured by the terminal device on the first resource β. The total power can be understood as the sum of multiple measured values α, or it can be understood as the total power measured on the first resource β. In the embodiments of this application, the total power may include one or more of the following: the power of the interference signal, the power of the thermal noise, the power of the serving cell, etc.
[0424] Let's take the first resource β occupying 2 symbols and 2 RBs, that is, occupying 48 REs, as an example. Then the first value β is the CLI (RSSI and / or RSRP) measured on these 48 REs, which can also be understood as the linear average of the total power (P) measured on these 48 REs.
[0425] The first interpretation: The linear averaging of total power can be understood as averaging the total power (P) across each RE. The first value β is then the ratio of the total power to the number of REs occupied by the first resource β. For example, if the first resource β occupies 48 REs, then the first value β is P / 48. Averaging the total power (P) across each RE can also be replaced by averaging the total power across each symbol and each RE.
[0426] The second interpretation: The linear average of total power can be understood as averaging the total power (P) across each symbol and each RB. The first value β is the total power averaged across one symbol and one RB. For example, if the first resource β occupies 2 symbols and 2 RBs, the linear average of the total power (the first value β) is P / (2×2).
[0427] The third interpretation: The linear average of total power can also be understood as averaging the total power (P) over each symbol, where the first value β is the total power averaged over one symbol. For example, if the first resource β occupies 2 symbols, the linear average of the total power (first value β) is P / 2; or, if the first resource β occupies 1 symbol, the linear average of the total power (first value β) is P.
[0428] The fourth interpretation: The linear average of total power can also be understood as averaging the total power (P) across each RB, with the first value β being the total power averaged across one RB. For example, if the first resource β occupies 2 RBs, the linear average of the total power (first value β) is P / 2; or, if the first resource β occupies 1 RB, then the linear average of the total power (first value β) is P.
[0429] It should be understood that in the embodiments of this application, the linear average of the total power can be averaged across any resource granularity, and this application does not specifically limit this. The linear average of the total power and the total power mentioned below can be referred to in the description herein, and will not be repeated hereafter.
[0430] It can be understood that, in accordance with the method of measuring the first value β on the first resource β as described above, the terminal device can obtain a first value on the first resource in the measurement resources of each time slot in multiple time slots, thereby determining multiple first values.
[0431] Similarly, following the method described above for obtaining the first value β from the first resource β, the terminal device can obtain a second value from the second resource in the measurement resources of each time slot in multiple time slots, thereby determining multiple second values.
[0432] For example, taking one of a plurality of second values as an example, let's say it's called the second value γ. The second value γ is the CLI measured on a second resource within a measurement resource in a time slot. For ease of description, this second resource is referred to as the second resource γ. Then, the second value γ is the CLI obtained by the terminal device performing CLI measurement on the second resource γ. Alternatively, the second value γ is the average of multiple measurement values measured by the terminal device in the second resource γ. For ease of description, these multiple measurement values are referred to as multiple measurement values γ (such as RSRP and / or RSSI). That is, the second value γ is the average of multiple measurement values γ, which are measured on the second resource γ, which belongs to a measurement resource in a time slot. Or, the second value γ can also be understood as the linear average of the total power measured by the terminal device on the second resource γ. The method for determining the second value γ is similar to the method for determining the first value β described above, and can be referred to the description above; it will not be repeated here.
[0433] For example, suppose the terminal device measures a value on each RE, and suppose the first resource in time slot i in Figure 17 is as shown in the first resource in Figure 16. Then the first resource in time slot i includes multiple REs (denoted as RE 1). The terminal device can measure a measurement value 1 (which can be RSRP or RSSI) on each RE 1 in the multiple REs 1, obtaining multiple measurement values 1. Based on the multiple measurement values 1, the first value corresponding to time slot i (such as the average of multiple measurement values 1) can be determined. The second resource in time slot i is as shown in the second resource in Figure 16. Then the second resource in time slot i includes multiple REs (denoted as RE 2). The terminal device can measure a measurement value 2 (which can be RSRP or RSSI) on each RE 2 in the multiple REs 2, obtaining multiple measurement values 2. Based on the multiple measurement values 2, the second value corresponding to time slot i (such as the average of multiple measurement values 2) can be determined.
[0434] In addition to the methods mentioned above for determining the first CLI and the second CLI, the first CLI and the second CLI can also be determined in the following ways.
[0435] The terminal device can measure one or more measurement values 1 (similar to the determination of multiple measurement values α) and one or more measurement values 2 (similar to the determination of multiple measurement values γ) in the measurement resources of each time slot in multiple time slots, as shown above. After the measurement resources in multiple time slots are measured, set 1 and set 2 can be obtained. Set 1 includes one or more measurement values 1 in the measurement resources of each time slot in multiple time slots; set 2 includes one or more measurement values 2 in the measurement resources of each time slot in multiple time slots. The first CLI can include one or more of the following: the average value of measurement values 1 in set 1, the maximum value of measurement values 1 in set 1, the minimum value of measurement values 1 in set 1, or the weighted average sum of measurement values 1 in set 1. The second CLI can include one or more of the following: the average value of measurement values 2 in set 2, the maximum value of measurement values 2 in set 2, the minimum value of measurement values 2 in set 2, or the weighted average sum of measurement values 2 in set 2.
[0436] It should be understood that the above description uses the example of configuring measurement resources in multiple time slots for a network device. In some possible implementations, the first information can be used to configure a first resource and a second resource in a time slot, that is, to configure a measurement resource (the measurement resource in a time slot), which includes a first resource and a second resource. For example, the first resource and the second resource are shown in Figure 16. In this case, the terminal device determines the first CLI in a similar way to the way a first value is determined above; the terminal device determines the second CLI in a similar way to the way a second value is determined above. Please refer to the description above, which will not be repeated here.
[0437] The second method, the first CLI and / or the second CLI, is measured on the first measurement resource.
[0438] As a second optional embodiment, method 900 further includes: the network device sending fourth information to the terminal device, the fourth information being used to indicate a first measurement resource, the first measurement resource being the measurement resource closest to the third resource, the first CLI and / or the second CLI being measured based on the first measurement resource, and the third resource being used to carry the second information; correspondingly, the terminal device receiving the fourth information from the network device.
[0439] The first measurement resource can be one or more time slots that are closest to the third resource among multiple time slots. The measurement resources in the multiple time slots can be configured with the first information. For example, a periodic CLI measurement resource configured for a network device, with a period of 4 slots, can be located in slots 0, 4, 8, etc., and therefore can also be understood as multiple measurement resources. The first measurement resource is located in a certain time slot, and among multiple time slots, this time slot is closest to the time slot where the third resource is located.
[0440] The third resource can be understood as the time-frequency domain resources used to carry the physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) of the first CLI and / or the second CLI. The third resource can be, but is not limited to, PUSCH resources or PUCCH resources. PUSCH resources are those used by PUSCH, and PUCCH resources are those used by PUCCH. The first measurement resource being the measurement resource closest to the third resource can also be understood as, in the time domain, the first measurement resource being the measurement resource in one or more time slots that is closest to the third resource among multiple time slots. The interval between the first measurement resource and the third resource must be greater than or equal to the CSI processing time.
[0441] The first CLI and / or the second CLI, which are obtained based on the first measurement resource, may include: the first CLI being measured on a first resource within the first measurement resource; and / or the second CLI being measured on a second resource within the first measurement resource.
[0442] Taking the time-domain units in the first and second time-domain units as examples, the first measurement resource can be the measurement resource in one or more time slots that is closest to the third resource among multiple time slots.
[0443] Referring to Figure 17, assuming the first measurement resource is a measurement resource within a single time slot, and time slot i+2 is the time slot closest to the third resource among multiple time slots, and assuming the third resource is in time slot i+8, then the CSI processing time can be 6 time slots. Therefore, the first CLI can be obtained based on the measurement of the first resource in time slot i+2; the second CLI can be obtained based on the measurement of the second resource in time slot i+2. The method for determining the first CLI is similar to, for example, the method for determining the first value β described above; and the method for determining the second CLI is similar to, for example, the method for determining the first value β described above. Please refer to the description above; it will not be repeated here.
[0444] Alternatively, in some scenarios, the first CLI is measured on a measurement resource in one time slot, and the second CLI is measured on a measurement resource in another time slot. For example, the second CLI is measured based on a second resource within a second measurement resource in another time slot (a time slot other than the first time slot), which is a full-duplex time slot among multiple time slots that is closest to the third resource. The first CLI is measured based on a first resource within a first measurement resource in a first time slot, which is a half-duplex time slot among multiple time slots that is closest to the third resource. The interval between the second and third measurement resources can be greater than or equal to the processing time of the CSI, and the interval between the first and third measurement resources can be greater than or equal to the processing time of the CSI. For example, the first CLI can be measured based on the first resource in time slot i+2, which is a half-duplex time slot. Then the second CLI can be measured based on the second resource in time slot i+1, which is a full-duplex time slot.
[0445] It should be understood that the fourth information can be interpreted as parameters configured by the network device, such as time restrictions for channel measurements (timeRestrictionForChannelMeasurements), CLI time restrictions (CLI RestrictionForChannelMeasurements), or interference measurement time restrictions. Furthermore, when the network device configures the fourth information, the terminal device can measure the first CLI and / or the second CLI based on the first measurement resource.
[0446] Furthermore, if the network device is not configured with the fourth information, the terminal device can measure the first CLI and / or the second CLI in accordance with the manner of the first optional embodiment. That is, the first CLI and the second CLI are measured on measurement resources in multiple time slots, which in the time domain are located at a position that occurs earlier than the third resource.
[0447] When the first CLI and / or the second CLI are obtained based on measurements from the first measurement resource, the first CLI and / or the second CLI can be determined in the following manner. The following explanation uses the first CLI as an example; the second CLI is determined similarly.
[0448] Optionally, the first CLI is the average value measured on the first measurement resource, or the average value of multiple first measurements measured on the first measurement resource, or the linear average of the total power measured on the first resource within the first measurement resource, wherein the multiple first measurements are measured on the first time-domain unit (or first resource) within the first measurement resource. For example, if the first measurement resource includes 2 symbols in the time domain and 2 RBs in the frequency domain, i.e., a total of 48 REs, and the first CLI is the first RSSI, then the average value measured on the first measurement resource can be understood as the average value of the RSSI measured on the 48 REs.
[0449] And / or, the second CLI is an average value measured on the first measurement resource, or an average of multiple second measurements measured on the first measurement resource, or a linear average of the total power measured on a second resource in the first measurement resource, wherein the multiple second measurements are measured on a second time-domain unit (or second resource) in the first measurement resource.
[0450] It should be understood that the determination of the first CLI and the second CLI is similar to the determination of the first value β in the above text. The determination of multiple first measurements and multiple measurements α is similar to the determination of multiple second measurements and multiple measurements γ. Please refer to the description above, and it will not be repeated here.
[0451] It should also be understood that, in the embodiments of this application, the average value obtained by measurement can also be understood as the average CLI, average interference, average power of total power, etc. This average value can be determined according to any resource granularity.
[0452] The multiple first measurements are obtained on the first time domain unit in the first measurement resource, which can also be understood as: the multiple first measurements are obtained on the first resource in the first measurement resource; the multiple second measurements are obtained on the second resource in the first measurement resource.
[0453] If multiple first measurements may include, for example, multiple RSRPs, then the first CLI may include the first RSRPs; and / or, if multiple first measurements may include, for example, multiple RSSIs, then the first CLI may include the first RSSIs. If multiple second measurements may include, for example, multiple RSRPs, then the second CLI may include the second RSRPs; and / or, if multiple second measurements may include, for example, multiple RSSIs, then the second CLI may include the second RSSIs.
[0454] For example, taking the case where the first measurement value is obtained on each RE, for the first measurement resource, where the first resource on the first time domain unit may include multiple REs, as shown in the first resource in FIG16, the terminal device can measure one RSRP and / or one RSSI on each RE in some or all of the REs, so that the terminal device can obtain multiple RSRPs and / or multiple RSSIs, that is, multiple first measurement values. Then the first CLI is the average of multiple first measurement values. In this way, the first CLI can accurately reflect the UE-to-UE CLI on the first resource in the first measurement resource.
[0455] Taking the second measurement value obtained on each RE as an example, for the first measurement resource, the second resource on the second time domain unit may also include multiple REs, as shown in the second resource in Figure 16. Then, the terminal device can measure one RSRP and / or one RSSI on each RE in some or all of these REs, allowing the terminal device to obtain multiple RSRPs and / or multiple RSSIs, i.e., multiple second measurement values. The second CLI is then the average of these multiple second measurement values. In this way, the second CLI can accurately reflect the inter-UE CLI on the second resource in the first measurement resource.
[0456] It is understood that in the first and / or second methods described above, the second CLI may include the third CLI and / or the fourth CLI mentioned above. Furthermore, when the second CLI includes both the third and fourth CLI, the methods for determining the third CLI and the fourth CLI are similar to those for determining the second CLI shown above.
[0457] For example, suppose the third CLI and the fourth CLI are measured on the second resource in the first measurement resource. Then the second resource includes resources for measuring the third CLI and resources for measuring the fourth CLI. The terminal device can then measure multiple third measurement values on the resource used to measure the third CLI and multiple fourth measurement values on the resource used to measure the fourth CLI. The third CLI can be the average of the multiple third measurement values, and the fourth CLI can be the average of the multiple fourth measurement values. The resources used to measure the third CLI and the resources used to measure the fourth CLI can be referred to the description in the third case above; the methods for determining the third CLI and the fourth CLI can be referred to the methods for determining the second CLI above, and will not be repeated here.
[0458] In addition to the method 900 described above, embodiments of this application also provide the following interference measurement method 1800.
[0459] Figure 18 is a schematic flowchart of an interference measurement method 1800 provided in an embodiment of this application. Method 1800 is applicable to a communication system 1000, and includes the following steps:
[0460] S1801, the network device sends seventh information to the terminal device. The seventh information is used to configure the fourth resource, which is used for CLI measurement. The fourth resource includes resources on the second time domain unit, which is a full-duplex time domain unit. Correspondingly, the terminal device receives the seventh information from the network device.
[0461] It should be understood that the second time-domain unit in method 1800 is similar to the second time-domain unit in method 900, as can be seen in the description above, and will not be repeated here.
[0462] The fourth resource can also be understood as interference measurement resource, CLI measurement resource, or measurement resource, etc., and is a time-frequency domain resource used for CLI measurements. The resources on the second time-domain unit are similar to the second resource in method 900.
[0463] In one scenario, the fourth resource may include the second resource in method 900. In another scenario, the fourth resource may include the first and second resources in method 900. That is, the fourth resource may include resources on the first time domain unit and resources on the second time domain unit.
[0464] S1802, the terminal device sends third information to the network device, the third information being used to indicate the first handover time and / or the number of handovers; the first handover time is the time required to switch between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource; the number of handovers is the number of times switching between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource in a plurality of consecutive second time domain units; wherein, the first frequency domain resource is the resource used for downlink transmission on the second time domain unit, and the second frequency domain resource is the resource used for uplink transmission on the second time domain unit.
[0465] It should be understood that the implementation of S1802 is similar to the implementation of the terminal device sending third information to the network device in method 900, and can be referred to the description above, which will not be repeated here.
[0466] In the interference measurement method of this application, the terminal device and the network device can determine the resources actually measured by the terminal device when performing CLI measurements based on a first handover time and / or the number of handovers. The first handover time can be a handover time supported by the terminal device, and the number of handovers can be a number of handovers determined under the premise of meeting the handover time supported by the terminal device. Alternatively, it can be understood that the network device needs to ensure that the capability requirements reported by the terminal device are met; that is, the network device ensures that the time required to switch between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource is greater than or equal to the handover time reported by the terminal device, or the network device ensures that the number of handovers between them is less than or equal to the number of handovers reported by the terminal device.
[0467] In this way, both the terminal device and the network device can determine the actual resources being measured, thereby determining which resources the CLI reported by the terminal device represents for inter-UE CLI. Furthermore, the switching of the filtering bandwidth between the first and second frequency domain resources during CLI measurement by the terminal device also meets the capabilities of the terminal device.
[0468] Similar to method 900, in addition to the first handover time, when the fourth resource also includes the first resource from method 900 (i.e., the resource on the first time domain unit), the terminal device can also report one or more of the second, third, fourth, or fifth handover times. Refer to the description in method 900 for details; further elaboration is omitted here.
[0469] Based on the above example, optionally, method 1800 further includes: S1803, the terminal device sends an eighth message to the network device, the eighth message indicating a fifth CLI, the fifth CLI being measured on the fourth resource; correspondingly, the network device receives the fifth CLI from the terminal device.
[0470] In one scenario, the fifth CLI can be a CLI measured by the terminal device on the fourth resource. That is, unlike method 900, the terminal device may not perform CLI measurements on different types of time-domain units in the fourth resource separately; that is, it may perform CLI measurements directly on the fourth resource without distinguishing between the types of time-domain units.
[0471] In another scenario, similar to method 900, the fourth resource includes a first resource and a second resource, the first resource being a resource of a first time-domain unit, the second resource being a resource of a second time-domain unit, the first time-domain unit being a half-duplex time-domain unit; and the first resource being used to measure the first CLI; the second resource being used to measure the second CLI, and the fifth CLI including the first CLI and the second CLI.
[0472] It should be understood that in this case, the implementation of the solution is similar to that of method 900, and can be referred to the description above, which will not be repeated here.
[0473] Furthermore, the fifth CLI may also include a third CLI and a fourth CLI, wherein the third CLI is measured on a first frequency domain resource on a second time domain unit; and the fourth CLI is measured on a second frequency domain resource on a second time domain unit. The first frequency domain resource on the second time domain unit and the second frequency domain resource on the second time domain unit belong to the fourth resource.
[0474] It should be understood that in this case, the method for determining the third CLI and the fourth CLI is similar to the method for determining the third CLI and the fourth CLI in method 900, and can be referred to the description above, which will not be repeated here.
[0475] Furthermore, the fifth CLI may consist only of the third CLI and the fourth CLI; or, the fifth CLI may include the first CLI, the third CLI, and the fourth CLI.
[0476] Based on the above embodiments, the resources for CLI measurements performed by the terminal device can also be determined in the following ways.
[0477] In feasible approach one, the fourth resource includes measurement resources in multiple time slots, and the fifth CLI is measured on measurement resources in multiple time slots.
[0478] It should be understood that the measurement resources in these multiple time slots are similar to the measurement resources in the multiple time slots configured with the first information in method 900. The difference is that the measurement resources in each of these multiple time slots may include a second resource on a second time domain unit; or, as in method 900, the measurement resources in each time slot may include a first resource and a second resource on a first time domain unit. Specific implementation details can be found in the description of method 900, and will not be repeated here.
[0479] In this case, the fifth CLI is measured on measurement resources across multiple time slots. The fifth CLI may include, but is not limited to, one or more of the following: the average of multiple fifth measurements measured on measurement resources across multiple time slots, the maximum value among multiple fifth measurements, the minimum value among multiple fifth measurements, or a weighted average of multiple fifth measurements.
[0480] The fifth measurement can be obtained from measurement resources in multiple time slots. The fifth measurement can include RSRP and / or RSSI.
[0481] Alternatively, in this case, the fifth CLI may include, but is not limited to, one or more of the following: multiple fifth values, the average of multiple fifth values, the maximum of multiple fifth values, the minimum of multiple fifth values, or a weighted average of multiple fifth values.
[0482] It should be understood that each measurement resource in multiple time slots can correspond to a fifth value. The method for determining multiple fifth values is similar to the method for determining multiple first values mentioned above. The difference is that the first value is determined on the first resource in a measurement resource, while the fifth value is determined on a measurement resource. Furthermore, the method for determining the fifth CLI based on multiple fifth values is similar to the method for determining the first CLI based on multiple first values, which can be referred to in the description above and will not be repeated here.
[0483] It is understandable that the determination of the fifth CLI is similar to that of the first CLI or the second CLI in the first method of method 900. Please refer to the description above, which will not be repeated here.
[0484] In feasible method two, the fourth resource includes the first measurement resource, and the fifth CLI is measured on the first measurement resource.
[0485] As an optional embodiment, method 1800 further includes: the network device sending fourth information to the terminal device. The fourth information is used to indicate a first measurement resource in the fourth resource, the first measurement resource being the measurement resource closest to the third resource, the fifth CLI being measured based on the first measurement resource, and the third resource being used to carry the second information; correspondingly, the terminal device receives the fourth information from the network device.
[0486] The fourth resource can be understood as the measurement resource in the multiple time slots mentioned above. The measurement resource in each of these multiple time slots may include the second resource on the second time domain unit; or, as in method 900, each measurement resource may include the first resource and the second resource on the first time domain unit. The third resource is the resource used for reporting the fifth CLI, and is similar to the third resource in method 900.
[0487] The first measurement resource in method 1800 is similar to the first measurement resource in method 900. When the measurement resource in each of the multiple time slots in method 1800 includes the second resource on the second time domain unit, the difference between the first measurement resource in method 1800 and the first measurement resource in method 900 is that the first measurement resource in method 1800 does not include the first resource on the first time domain unit. Alternatively, if the measurement resources in the multiple time slots of method 1800 are the same as those in the multiple time slots of method 900, and the measurement resource in each time slot includes both the first and second resources on the first time domain unit, then the first measurement resource in method 1800 can also be the same as the first measurement resource in method 900.
[0488] Based on the above embodiments, the fifth CLI is the average of multiple fifth measurement values measured on the first measurement resource, or the linear average of the total power measured on the first measurement resource, or the average value measured on the first measurement resource. The method for determining the fifth CLI is similar to the method for determining the first value β described above. The method for determining multiple fifth measurement values is similar to the method for determining multiple measurement values α, and can be referred to the description above; it will not be repeated here.
[0489] Among them, multiple fifth measurements may be obtained from some or all of the REs in the first measurement resource, and the fifth measurements may include RSRP and / or RSSI.
[0490] In this way, the fifth CLI can accurately represent the inter-UE CLI on the first measurement resource, and since the first measurement resource is the measurement resource in one or more time slots that is closest to the third resource among multiple time slot measurement resources, the fifth CLI can accurately reflect the inter-UE CLI on the current channel.
[0491] It is understood that since CLI can be represented by RSRP and / or RSSI, a fifth CLI can include a fifth RSRP and / or a fifth RSSI.
[0492] In addition to the methods 900 and 1800 described above, embodiments of this application also provide the following interference measurement method 1900.
[0493] Figure 19 is a schematic flowchart of an interference measurement method 1900 provided in an embodiment of this application. Method 1900 is applicable to a communication system 1000, and includes the following steps:
[0494] S1901, the network device sends fourth and fifth information to the terminal device. The fifth information is used to indicate measurement resources in multiple time slots, and the fourth information is used to indicate the first measurement resource in the first time slot. The first time slot is the time slot closest to the third resource among multiple time slots. The third resource is used to carry sixth information. The sixth information is used to indicate the sixth CLI. The sixth CLI is the average of multiple sixth measurement values measured on the first measurement resource, or the linear average of the total power measured on the first measurement resource, or the average value measured on the first measurement resource. The terminal device receives the fourth and fifth information from the network device.
[0495] It should be understood that the first time slot can be one or more time slots closest to the third resource among multiple time slots. This application does not specifically limit this. The interval between the first time slot and the time slot where the third resource is located must be greater than or equal to the CSI processing time. The first measurement resource exists on the first time slot.
[0496] The sixth CLI is the average of multiple sixth measurements obtained on the first measurement resource. Alternatively, the sixth CLI can be defined as the CLI obtained solely based on the first measurement resource in the first time slot. That is, it is not the CLI obtained based on measurements from multiple time slots. It should also be understood that the determination of the sixth CLI is similar to the determination of the first value β mentioned above, and the determination of multiple sixth measurements is similar to the determination of multiple measurement values α, as described above. Further details will not be repeated here.
[0497] The measurement resources in multiple time slots are similar to those in multiple time slots in method 900. The difference is that, in method 1900, the measurement resources in each time slot of multiple time slots may include a first resource on a first time domain unit and / or a second resource on a second time domain unit.
[0498] Similarly, the first measurement resource in the first time slot is similar to the first measurement resource in method 900. The difference is that the first measurement resource in method 1900 may include a first resource on a first time domain unit and / or a second resource on a second time domain unit.
[0499] In addition, in one case, the sixth CLI can be understood as a CLI obtained by performing CLI measurement on the first measurement resource. That is, the difference from method 900 is that even if the first measurement resource includes the first resource on the first time domain unit and the second resource on the second time domain unit, the terminal device may not perform CLI measurement on the first resource and the second resource respectively, that is, perform CLI measurement without distinguishing the type of time domain unit.
[0500] In another scenario, the first measurement resource includes a first resource and a second resource. The sixth CLI can then be a CLI obtained by performing CLI measurements on the first and second resources. Alternatively, the first resource can be used to measure a first CLI on a first time-domain unit, and the second resource can be used to measure a second CLI on a second time-domain unit, where the first time-domain unit is a half-duplex time-domain unit and the second time-domain unit is a full-duplex time-domain unit; the sixth CLI includes both the first and second CLIs.
[0501] In this case, the way the terminal device measures the first CLI and the second CLI is similar to the implementation of measuring the first CLI and the second CLI in the first measurement resource in method 900. Please refer to the description above, and it will not be repeated here.
[0502] Optionally, the second CLI may include at least one of a third CLI and a fourth CLI, wherein the third CLI is measured on a first frequency domain resource on the second time domain unit, and the fourth CLI is measured on a second frequency domain resource on the second time domain unit. Furthermore, the first frequency domain resource on the second time domain unit and the second frequency domain resource on the second time domain unit belong to the first measurement resource.
[0503] It should be understood that the way the terminal device measures the third CLI and / or the fourth CLI is similar to the implementation of measuring the third CLI and / or the fourth CLI in the first measurement resource in method 900, and can be referred to the description above, which will not be repeated here.
[0504] S1902, the terminal device sends a sixth message to the network device, the sixth message being used to indicate a sixth CLI; correspondingly, the network device receives the sixth message from the terminal device. The sixth CLI is the average of multiple sixth measurement values obtained on the first measurement resource.
[0505] It should be understood that CLI can be RSRP and / or RSSI. A sixth measurement can include RSRP and / or RSSI. A sixth CLI includes a sixth RSRP, which can be the average of multiple RSRPs; a sixth CLI includes a sixth RSSI, which is the average of multiple RSSIs. Alternatively, a sixth CLI can be a linear average of the total power measured on the first measurement resource.
[0506] The interference measurement method of this application accurately reflects the inter-UE CLI on the first measurement resource because the sixth CLI is the average of multiple sixth measurements. Furthermore, because the first measurement resource is the measurement resource in one or more time slots closest to the third resource among multiple time slots, the sixth CLI accurately reflects the inter-UE CLI on the current channel. This allows network devices to combine the sixth CLI for more accurate interference avoidance.
[0507] As an optional embodiment, the first measurement resource includes a second resource on a second time domain unit, the second time domain unit being a full-duplex time domain unit; method 1900 further includes: the terminal device sending third information to the network device, the third information indicating a first handover time and / or a number of handovers; the first handover time is the time required to switch between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource; the number of handovers is the number of times switching between downlink transmission on the first frequency domain resource and CLI measurement on the second frequency domain resource on a plurality of consecutive second time domain units; wherein, the first frequency domain resource is a resource on the second time domain unit used for downlink transmission, and the second frequency domain resource is a resource on the second time domain unit used for uplink transmission. Correspondingly, the network device receives the third information from the terminal device.
[0508] It should be understood that the implementation of this solution is similar to the implementation of method 900, and can be referred to the description above, which will not be repeated here.
[0509] In addition to the first switching time, similar to method 900, when the first measurement resource includes the first resource on the first time domain unit and the second resource on the second time domain unit, the terminal device may also report one or more of the second switching time, the third switching time, the fourth switching time, or the fifth switching time. Similar to the implementation method in method 900, please refer to the description above, and it will not be repeated here.
[0510] It should be noted that the order of the methods listed above does not imply the order of execution. The execution order of each process should be determined by its function and internal logic.
[0511] The interference measurement method of the present application embodiment has been described in detail above with reference to Figures 9 to 19. The communication device of the present application embodiment will be described in detail below with reference to Figures 20 to 22. The communication device includes modules or units for performing each part of the above embodiments. The modules or units can be software, hardware, or a combination of software and hardware. The following is only a brief illustrative description of the communication device; for details of the implementation, please refer to the description of the foregoing method embodiments, which will not be repeated below.
[0512] Figure 20 is a schematic block diagram of a communication device 2000 provided in an embodiment of this application. As shown in Figure 20, the communication device 2000 includes a receiving module 2001 and a transmitting module 2002.
[0513] In one possible implementation, the communication device 2000 is used to implement the steps corresponding to the terminal device in the method 900 described above.
[0514] The receiving module 2001 is used to receive first information, which is used to configure first resources and second resources. The first resources are used to measure the first cross-link interference (CLI) on the first time domain unit, and the second resources are used to measure the second CLI on the second time domain unit. The first time domain unit is a half-duplex time domain unit, and the second time domain unit is a full-duplex time domain unit. The transmitting module 2002 is used to transmit second information, which is used to indicate the first CLI and the second CLI.

[0520] Optionally, the first CLI includes a first RSRP and / or a first RSSI; the second CLI includes a second RSRP and / or a second RSSI.
[0521] In another possible implementation, the communication device 2000 is used to implement the steps corresponding to the network device in the method 900 described above.
[0522] The transmitting module 2002 is used to transmit first information, which is used to configure first resources and second resources. The first resources are used to measure the first cross-link interference (CLI) on the first time domain unit, and the second resources are used to measure the second CLI on the second time domain unit. The first time domain unit is a half-duplex time domain unit, and the second time domain unit is a full-duplex time domain unit. The receiving module 2001 is used to receive second information, which is used to indicate the first CLI and the second CLI.
[0523] Optionally, the second information includes first sub-information and second sub-information, wherein the first sub-information is used to indicate the first CLI and the second sub-information is used to indicate the second CLI; or, the second information is used to indicate the first CLI and a first difference, wherein the first difference is the difference between the second CLI and the first CLI; or, the second information is used to indicate the second CLI and a second difference, wherein the second difference is the difference between the first CLI and the second CLI.
