Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a communication method and related apparatus. Background Technology

[0002] Wireless communication can be a transmission communication between two or more communication devices that does not propagate through conductors or cables. Generally, the two or more communication devices include network devices and terminal devices, or the two or more communication devices include different terminal devices.

[0003] Currently, during communication between different communication devices, the signal sender can send a measurement signal (e.g., a reference signal), and the corresponding signal receiver can receive the measurement signal and perform measurements based on it to obtain relevant information about the channel (e.g., channel interference information). Subsequently, resource management can be implemented based on this relevant information about the channel.

[0004] However, improving measurement performance during the aforementioned measurement process is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides a communication method and related apparatus for improving the accuracy of interference measurement, thereby improving communication performance.

[0006] This application provides a communication method applied to, or executed by, a first communication device. The first communication device may be a communication equipment (such as a terminal device or network device), or it may be a component of the communication equipment (e.g., a circuit or chip responsible for communication functions, such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip, etc.). Alternatively, the first communication device may also be a logic module or software capable of implementing all or part of the functions of the communication equipment. In this method, the first communication device receives first information, which is used to configure first power information for interference measurement (IM) resources; the first communication device performs measurements based on the interference measurement resources and the first power information.

[0007] Based on the above scheme, the first information received by the first communication device is used to configure the first power information of the interference measurement resources. Subsequently, the first communication device can perform measurements based on the interference measurement resources and the first power information. In this way, the first communication device can measure the interference measurement resources based on the power information configured in the first information, which can improve the accuracy of interference measurement and thus improve communication performance.

[0008] It should be understood that interference measurement resources can be resources used for interference measurement. For example, interference measurement resources can be channel state information interference measurement (CSI-IM) resources, or interference measurement resources can be other names specified in standards / protocols, which are not limited here.

[0009] It should be understood that an interference measurement resource may include one or more resources, and the first power information of the interference measurement resource may be used to indicate (or determine) the power of the signal carried by the one or more resources included in the interference measurement resource. For example, the first power information may be used to indicate (or determine) the power of the signal carried by each resource included in the interference measurement resource.

[0010] Optionally, the first communication device may also receive configuration information for configuring interference measurement resources. This configuration information and the aforementioned first information may be carried in the same message / signaling / information; for example, the configuration information may include the aforementioned first information, or the aforementioned first information may include the configuration information. Alternatively, the configuration information and the aforementioned first information may be carried in different messages / signaling / information.

[0011] It should be noted that the process of the first communication device measuring based on the interference measurement resource and the first power information may include: the first communication device measuring the interference measurement resource based on the first power information to obtain interference measurement result information; and / or, after obtaining the interference measurement result information by measuring the interference measurement resource, the first communication device processing the interference measurement result information based on the first power information (e.g., mathematical operations, updates, or adjustments).

[0012] In one possible implementation of the first aspect, the first power information includes a power value and / or a power offset parameter relative to a reference power.

[0013] Based on the above scheme, the first power information configured in the first information configuration may include power values ​​and / or power offset parameters, which can configure the power of interference measurement resources in a variety of ways to improve the flexibility of the scheme implementation.

[0014] Optionally, as described above, the interference measurement resource may include one or more resources. Accordingly, in the above scheme, the first power information may include the power values ​​of 0 or 1 or more resources included in the interference measurement resource, and / or, the first power information may include the power offset parameters of 0 or 1 or more resources included in the interference measurement resource.

[0015] In one possible implementation of the first aspect, the method further includes: the first communication device receiving second information for determining the reference power.

[0016] Based on the above scheme, the first communication device can also receive the second information and determine the reference power based on the second information, so that the first communication device can determine the power value of the signal carried by the interference measurement resource based on the reference power and the power offset parameter included in the first power information.

[0017] Optionally, the aforementioned reference power can be pre-configured to reduce transmission overhead.

[0018] In one possible implementation of the first aspect, the method further includes: the first communication device transmitting third information, the third information being used to indicate interference measurement result information, the interference measurement result information being determined based on the interference measurement resources and the first power information.

[0019] Based on the above scheme, after the first communication device obtains the interference measurement result information by measuring the interference measurement resources and the first power information, the first communication device can also send third information indicating the interference measurement result information, so that the receiver of the third information (e.g., the second communication device) can determine the interference measurement result corresponding to the interference measurement resources, so that the receiver can perform resource management based on the interference measurement result.

[0020] Optionally, the aforementioned resource management may include radio resource management (RRM), data transmission, etc. For example, the RRM may include one or more of the following: cell selection and reselection, power control, access control, handover management, load control, frequency allocation (e.g., carrier aggregation (CA) related configurations, including but not limited to activating and deactivating carrier aggregation, configuring aggregated carrier sets, allocating resource blocks, etc.), channel allocation, and interference management.

[0021] Optionally, the first communication device may not send the third information. For example, if the first communication device determines that the interference indicated by the interference measurement result is below or equal to a threshold, it can silently allow the second communication device to understand that the interference is low, thereby reducing transmission overhead.

[0022] As an example, the aforementioned interference measurement result information includes signal quality information of the signal carried by the interference measurement resource, and / or channel state information (CSI).

[0023] Optionally, the above signal quality information may include one or more of the following: reference signal received power (RSRP), interference measurement reference signal received power (IM-RSRP), signal to interference plus noise ratio (SINR), and signal to noise ratio (SNR).

[0024] Optionally, the CSI mentioned above may include one or more of the following: channel quality indicator (CQI), RSRP, reference signal received quality (RSRQ), received signal strength indicator (RSSI), precoding matrix indicator (PMI), rank indicator (RI), or layer indicator (LI).

[0025] In one possible implementation of the first aspect, the interference measurement result information includes at least one of the following: an index of the signal carried by the interference measurement resource, an index of the interference measurement resource, an index of the reference signal corresponding to the interference measurement result information, or a resource index corresponding to the interference measurement result information.

[0026] Based on the above scheme, the interference measurement result information may include at least one of the above indexes, so that the recipient of the third information can determine the measurement object (i.e., resources and / or signals) corresponding to the interference measurement result information based on the at least one index, so as to obtain the interference situation corresponding to the measurement object.

[0027] A second aspect of this application provides a communication method applied to a first communication device, such as a second communication device executed by a second communication device. The second communication device can be a communication equipment (e.g., a terminal device or a network device), or it can be a component of the communication equipment (e.g., a circuit or chip responsible for communication functions, such as a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, etc.), or it can be a logic module or software capable of implementing all or part of the functions of the communication equipment. In this method, the second communication device determines first information, which is used to configure first power information for interference measurement resources; the second communication device then transmits the first information.

[0028] Based on the above scheme, the first information sent by the second communication device to the first communication device is used to configure the first power information of the interference measurement resources. Subsequently, the first communication device can perform measurements based on the interference measurement resources and the first power information. In this way, the first communication device can measure the interference measurement resources based on the power information configured in the first information, which can improve the accuracy of interference measurement and thus improve communication performance.

[0029] In one possible implementation of the second aspect, the first power information includes a power value and / or a power offset parameter relative to a reference power.

[0030] Based on the above scheme, the first power information configured in the first information configuration may include power values ​​and / or power offset parameters, which can configure the power of interference measurement resources in a variety of ways to improve the flexibility of the scheme implementation.

[0031] In one possible implementation of the second aspect, the method further includes: the second communication device transmitting second information for determining the reference power.

[0032] Based on the above scheme, the second communication device can also send second information to the first communication device for determining the reference power, so that the first communication device can determine the power value of the signal carried by the interference measurement resource based on the reference power and the power offset parameter included in the first power information.

[0033] Optionally, the aforementioned reference power can be pre-configured to reduce transmission overhead.

[0034] In one possible implementation of the second aspect, the method further includes: the second communication device receiving third information, the third information being used to indicate interference measurement result information, the interference measurement result information being determined based on the interference measurement resources and the first power information.

[0035] Based on the above scheme, after the first communication device obtains the interference measurement result information by measuring the interference measurement resources and the first power information, the first communication device can also send third information indicating the interference measurement result information to the second communication device, so that the second communication device can determine the interference measurement result corresponding to the interference measurement resources, so that the second communication device can perform wireless resource management based on the interference measurement result.

[0036] Optionally, the first communication device may not send the third information. For example, if the first communication device determines that the interference indicated by the interference measurement result is below or equal to a threshold, it can silently allow the second communication device to understand that the interference is low, thereby reducing transmission overhead.

[0037] As an example, the interference measurement result information includes signal quality information of the signal carried by the interference measurement resource, and / or, channel state information.

[0038] In one possible implementation of the second aspect, the interference measurement result information includes at least one of the following: an index of the signal carried by the interference measurement resource, an index of the interference measurement resource, an index of the reference signal corresponding to the interference measurement result information, or a resource index corresponding to the interference measurement result information.

[0039] Based on the above scheme, the interference measurement result information may include at least one of the above indexes, enabling the second communication device to determine the measurement object (i.e., resources and / or signals) corresponding to the interference measurement result information based on the at least one index, so as to obtain the interference situation corresponding to the measurement object.

[0040] In one possible implementation of the first or second aspect, the interference measurement resource is a zero-power interference measurement resource.

[0041] Based on the above scheme, the interference measurement resource used by the first communication device can be a zero-power interference measurement resource, that is, the interference measurement resource can not carry other signals, so that the interference measurement result information obtained by the first communication device can reflect the interference situation caused by the interference signal on the interference measurement resource.

[0042] In one possible implementation of the first or second aspect, the interference measurement resource is a non-zero power interference measurement resource, and the first power information is used to determine at least two power information corresponding to the interference measurement resource.

[0043] Based on the above scheme, the interference measurement resource used by the first communication device can be a non-zero power interference measurement resource, that is, the interference measurement resource can carry a non-zero power signal, so that the interference measurement result information obtained by the first communication device can reflect the interference situation caused by the non-zero power signal on the interference measurement resource.

[0044] Furthermore, when the interference measurement resource is a non-zero power interference measurement resource, the first communication device can determine at least two power information corresponding to the interference measurement resource based on the first power information. Compared to the method of averaging interference measurements on different resources, in the above scheme, the different resources included in the interference measurement resource can be configured with their own power information (for example, the interference measurement resource can correspond to at least two signals with different power), enabling the first communication device to perform measurements based on the corresponding power information of each resource and obtain interference measurement results, thereby further improving the accuracy of the measurement.

[0045] Optionally, the interference measurement resources include zero-power interference measurement resources and non-zero-power interference measurement resources.

[0046] As an example, as described above, interference measurement resources may include one or more resources. In the case where the interference measurement resources include zero-power interference measurement resources, the first power information may indicate the power of the zero-power interference measurement resource. For example, the interference measurement resource may include a zero-power channel state information reference signal (ZP CSI-RS) resource.

[0047] As another example, as described above, interference measurement resources may include one or more resources. In the case where the interference measurement resources include non-zero power interference measurement resources, the first power information may indicate the power of the non-zero power interference measurement resources. For example, the interference measurement resources may include non-zero power channel state information reference signal (NZP CSI-RS) resources.

[0048] In one possible implementation of the first or second aspect, the interference measurement resource includes N frequency domain resources, where N is a positive integer; wherein the first power information is used to determine the power information corresponding to the N frequency domain resources.

[0049] Based on the above scheme, the interference measurement resources may include N frequency domain resources, enabling the first communication device to determine the power information corresponding to the N frequency domain resources based on the first power information, and to perform measurement based on the power information corresponding to the N frequency domain resources, thereby improving the accuracy of interference measurement of the N frequency domain resources.

[0050] Optionally, N is greater than 1, and the power information corresponding to different frequency domain resources among the N frequency domain resources can be the same or different. For example, the first communication device can determine the N power information corresponding to the N frequency domain resources based on the first power information, and can measure the N frequency domain resources based on the N power information. Compared with the method of averaging interference measurements on different frequency domain resources, the first communication device can measure based on the corresponding power information of each frequency domain resource and obtain the interference measurement result, which can further improve the accuracy of the measurement.

[0051] Optionally, a frequency domain unit may indicate one or more resources in the frequency domain, including one or more subcarriers, one or more subcarrier groups, one or more resource blocks, one or more physical resource blocks, one or more resource block groups, one or more partial bandwidths, or other implementations specified by standards / protocols.

[0052] In one possible implementation of the first or second aspect, a frequency domain unit of the i-th frequency domain resource of the N frequency domain resources includes M resource units, where i is from 1 to N and M is an integer greater than or equal to 1; wherein the first power information is used to determine the power information corresponding to the M resource units.

[0053] Based on the above scheme, any frequency domain resource (i.e., the i-th frequency domain resource) of N frequency domain resources can contain a number of resource units (i.e., M resource units). The first communication device can determine the power information corresponding to the number of resource units based on the first power information, and realize finer-grained measurement based on the power information corresponding to each resource unit, which can further improve the accuracy of measurement.

[0054] Optionally, a resource unit can be the smallest unit of time-frequency resources, and may include one or more resources in the time-frequency domain. For example, it may include one or more symbols in the time domain and one or more subcarriers in the frequency domain. For instance, a resource unit may be a resource of one symbol in the time domain and one subcarrier in the frequency domain. For example, a resource unit may be a resource element (RE), which may reside in one or more resource grids (RGs). Alternatively, a resource unit may also be another implementation specified by the standard / protocol.

[0055] In one possible implementation of the first or second aspect, the first power information satisfies any one of the following:

[0056] The first power information includes first indication information and / or second indication information. The first indication information is used to indicate the resource pattern of the M resource units, and the second indication information is used to indicate the power information corresponding to the resource pattern of the M resource units.

[0057] The first power information includes the power information of one or more time units corresponding to the M resource units;

[0058] The first power information includes the power information corresponding to the M resource units; or

[0059] The first power information includes the power information of one or more groups of resource units corresponding to the M resource units.

[0060] Based on the above scheme, the first power information can be used to determine the power information corresponding to M resource units through the above methods, so as to improve the flexibility of the scheme implementation.

[0061] In one possible implementation of the first or second aspect, the interference measurement resource includes P resource units in a frequency domain unit, where P is a positive integer; wherein the first power information is used to determine the power information corresponding to the P resource units.

[0062] Based on the above scheme, the interference measurement resources may include P resource units, enabling the first communication device to determine the power information corresponding to the P resource units based on the first power information, and to perform measurement based on the power information corresponding to the P resource units, thereby improving the accuracy of interference measurement of the P resource units.

[0063] Optionally, P is greater than 1, and the power information corresponding to different resource units among the P resource units can be the same or different. For example, the first communication device can determine the P power information corresponding to the P resource units based on the first power information, and can measure the P resource units based on the P power information. Compared with the method of averaging interference measurements on different resource units, the first communication device can measure based on the corresponding power information of each resource unit and obtain the interference measurement result, which can further improve the accuracy of the measurement.

[0064] In one possible implementation of the first or second aspect, the first power information satisfies any one of the following:

[0065] The first power information includes third indication information and / or fourth indication information. The third indication information is used to indicate the resource pattern of the P resource units, and the fourth indication information is used to indicate the power information corresponding to the resource pattern of the P resource units.

[0067] The first power information includes the power information corresponding to the P resource units; or

[0068] The first power information includes the power information of one or more groups of resource units corresponding to the P resource units.

[0069] Based on the above scheme, the first power information can be used to determine the power information corresponding to P resource units through the above methods, so as to improve the flexibility of the scheme implementation.

[0071] Based on the above scheme, in addition to being used for interference measurement of the first radio access technology, the interference measurement resources can also be used to carry communication signals of the second radio access technology. This allows the above scheme to be applied to scenarios where two or more radio access technologies share spectrum (e.g., multi-radio access technology spectrum sharing, MRSS), and improves the accuracy of interference measurement in such scenarios, thereby improving communication performance.

[0098] 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.

Pre-configuration is similar to configuration and can be parameter information or parameter values ​​that the network device and the terminal device have negotiated in advance, or parameter information or parameter values ​​that the network device and / or the terminal device use as specified by the standard protocol, or parameter information or parameter values ​​that are pre-stored in the network device and / or the terminal device. This application does not limit this.

[0107] Optionally, configuration can also be understood as: instructions.

[0108] Furthermore, these values ​​and parameters can be changed, updated, or reconfigured.

[0109] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0110] (5) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by 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.

[0111] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0112] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0113] (6) In the embodiments of this application, "instruction" may 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 an association 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 instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0114] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0115] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0116] In one possible implementation, this application can be applied to Narrow Band Internet of Things (NB-IoT) systems, Global System for Mobile Communications (GSM), Enhanced Data Rate for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), Time Division-Synchronization Code Division Multiple Access (TD-SCDMA), Integrated Sensing and Communication (ISAC) systems, Wireless Local Area Networks (WLANs), Short-Range Wireless Communication Systems (such as sidelinks, Wireless Fidelity (Wi-Fi or WiFi), Bluetooth, etc.), Wired Networks, and Vehicle-to-Everything (V2X) systems. Everything, including V2X communication systems, device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, 4th generation (4G) mobile communication systems (such as Long Term Evolution (LTE) systems), LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th generation (5G) mobile communication systems (such as New Radio (NR) systems), future evolved New Radio (NR) wireless communication systems, or other similar communication systems, is not restricted.For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, and future OFDM systems and similar systems. For instance, this application can be applied to the three major application scenarios of next-generation 5G mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and / or enhanced machine-type communication (eMTC).

[0117] Please see Figure la This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure la As shown, the communication system includes RAN 100 and core network 200. Optionally, the communication system 1000 may also include Internet 300. RAN 100 includes at least one RAN node (e.g., Figure la 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure la RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure la (Not shown in the image). Terminal 120 connects wirelessly to RAN node 110, and RAN node 110 connects wirelessly or via a wired connection to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminals can connect to each other, and RAN nodes can connect to each other, via wired or wireless connections.

[0118] Figure lb An example diagram of an O-RAN system is shown. An O-RAN system may include components other than those shown in the diagram. As illustrated, access network equipment (such as RAN equipment, for example, an eNB, gNB, or next-generation access network equipment) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0119] In one possible implementation, this application can be applied to long-term evolution (LTE) wireless communication systems, NR wireless communication systems, and future new radio (NR) wireless communication systems. For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, future OFDM systems, and OFDM-like systems.

[0120] As an example, a RAN node can be a satellite base station or a satellite, as described below. Figures lc-g illustrate. Figure lc and Figure ld This is a schematic diagram of a communication system applicable to embodiments of this application.

[0121] like Figure lc and Figure ld As shown, satellite base stations provide communication services to terminals. For example, a satellite base station transmits downlink data to a terminal, where the data is encoded using channel coding, and the channel-coded data is then transmitted to the terminal after constellation modulation. Similarly, a terminal transmits uplink data to a satellite base station; the uplink data can also be encoded using channel coding, and the encoded data is then transmitted to the satellite base station after constellation modulation. Additionally, as... Figure ld As shown, satellite base stations can also communicate with ground base stations; that is, a satellite can act as a base station or as a terminal.

[0122] In this application, "satellite" can refer to unmanned aerial vehicles (UAVs), hot air balloons, low-Earth orbit (LEO) satellites, medium-Earth orbit (MEO) satellites, high-Earth orbit (HEO) satellites, etc. "Satellite" can also refer to non-terrestrial base stations or non-terrestrial equipment, etc.

[0123] It should be understood that this application can be applied to scenarios involving communication between network devices. Figure ld The scenario shown can also be seen as an example of network devices communicating with each other, where both the satellite and the base station can be considered as a network device.

[0124] As one implementation method, this application can be applied to inter-satellite link communication systems. For example... Figure ld The communication between satellite #1 and satellite #2 is shown.

[0125] like Figure leAs shown, the inter-satellite link communication system can be divided into two main parts: an acquisition, pointing, and tracking (APT) subsystem (including the APT module and APT transmitter / receiver) and a communication subsystem (including the communication module and transceiver antennas). The communication subsystem is primarily responsible for the transmission of inter-satellite information and forms the core of the inter-satellite communication system. The APT system is mainly responsible for acquisition, alignment, and tracking between satellites. Acquisition involves determining the direction of the incoming incident signal, and alignment involves adjusting the transmitted wave to aim at the receiving direction. Tracking involves continuously adjusting the APT for alignment and acquisition throughout the communication process. To minimize attenuation and interference in the channel while maintaining high security and transmission rate, the APT must be adjusted in real time to continuously adapt to changes.

[0126] It should be understood that current APT systems are all optical systems, which have the disadvantage of being difficult to align and requiring mechanical adjustment of the pointing. Most existing communication subsystems are optical communication systems, with some microwave band systems, and most use a single high-gain antenna. Existing APT systems and communication subsystems are independent systems. The disadvantages are that optical communication is susceptible to vibration and other factors, resulting in unstable data rates; millimeter-wave frequencies are low, communication capacity is low, and the antenna requires mechanical adjustment of its pointing.

[0127] As another implementation, this application can be applied to scenarios where terminal devices communicate with each other, such as Internet of Things (IoT) communication systems.

[0128] Figure lf This is a schematic diagram of a wireless screen mirroring method applicable to embodiments of this application. A terminal device (e.g., a smartphone) establishes a network connection with a television. The smartphone transmits the content to be mirrored onto the television to the television. After receiving the content transmitted by the smartphone, the television displays the content on its screen.

[0129] It should be understood that Figure lf The screen mirroring scenario shown can be seen as an example of communication between terminal devices, where both smartphones and televisions can be considered as terminal devices.

[0130] As another implementation method, this application can be applied to integrated access and backhaul (IAB) systems.

[0131] Figure lg This is a schematic diagram of an IAB system applicable to embodiments of this application. For example... Figure lgAs shown, an IAB can include an IAB donor, an IAB node, and a terminal. The link between the IAB donor and the IAB node is a backhaul link, and the link between the terminal and the IAB node is an access link. This application can be applied to both parties communicating in a backhaul link or to both parties communicating in an access link.

[0132] It should be understood that the above system application scenarios are only examples, and this application can also be applied to other scenarios, which will not be listed here.

[0133] In wireless communication systems (e.g.) Figures la-g In any of the systems shown in the accompanying figures, wireless communication resources generally include time-frequency resources. The following will use an NR system as an example to introduce time-frequency resources. It should be understood that NR can also be replaced with 5G or 5G NR.

[0134] 1. Parameter set (Numerology).

[0135] 5G NR introduces the concept of Numerology, which includes sub-carrier spacing (SCS) and corresponding parameters such as symbol length and cyclic prefix (CP) length. Because there is a certain mapping relationship between SCS and symbol length and CP length, SCS is often used instead of Numerology in some literature.

[0136] For example, the parameters involved in Numerology are shown in Table 2.

[0137] Table 2

[0138] μ SCS CP Supported frequency ranges (FR) 0 15 Normal FR1 1 30 Normal FR1 2 60 Normal, Extended FR1, FR2 3 120 Normal FR2 4 240 Normal FR2

[0139] In Table 2, μ represents the subcarrier spacing index, or μ represents the parameter set numberology, CP length includes the normal CP length and the extended CP length, and FR represents the frequency range (FR).

[0140] 2. Frame structure.

[0141] In NR systems, time-domain units include symbols, slots, subframes, half-frames, and frames. A frame lasts 10 ms and can be divided into 10 subframes, numbered 0-9. Subframes numbered 0-4 form one half-frame, and subframes numbered 5-9 form another half-frame. Each subframe lasts 1 ms. Each subframe can include one or more slots. Under normal CP, each slot includes 14 symbols; under extended CP, each slot includes 12 symbols.

[0142] For example, the number of time slots included in each subframe is related to the SCS, and the relationship between the two is shown in Table 3.

[0143] Table 3

[0144] Subcarrier spacing (kHz) Number of slots per subframe 15 1 30 2 60 4 120 8 240 16 480 32 960 64

[0145] like Figure 2a The example shown is a schematic diagram of a 5G NR frame structure, including:

[0146] Frame: Length is fixed at 10ms, frame number range: 0~1023.

[0147] Subframe: The length is fixed at 1ms, and the subframe number ranges from 0 to 9.

[0148] Time slot: When using normal CP, the length is 14 symbols. Since the symbol length is not fixed, the time slot length is also not fixed. When the SCS is 60kHz, extended CP can also be used, in which case the time slot length is 12 symbols. Optionally, the time slot is the smallest unit for data scheduling.

[0149] Symbol: Length is not fixed and is related to SCS. Optional, the symbol is the basic unit of modulation.

[0150] Generally, in the physical layer, a symbol can contain several sampling points, and a sampling point can be the smallest time unit of the physical layer.

[0151] Furthermore, the scheduling time unit in the 5G NR data domain is the time slot. The number of symbols contained in a time slot is fixed, but the length of the symbol is related to the SCS (Segment Classification). The following will illustrate the relationship between frames, subframes, time slots, and symbols using SCS of 30kHz and 120kHz as examples.

[0152] like Figure 2b and Figure 2c The examples shown illustrate the relationships between frames, subframes, time slots, and symbols for SCS values ​​of 30kHz and 120kHz, respectively.

[0153] 3. Symbol type and slot format.

[0154] Generally, OFDM symbols include three types, namely:

[0155] Downlink: Represented by the letter D, it is used for downlink transmission.

[0156] Uplink: Represented by the letter U, used for uplink transmission.

[0157] Flexible: Represented by the letter F, it can be used for uplink transmission as well as downlink transmission, and can also be used as a guard period (GP) or reserved resources.

[0158] Optionally, each time slot can be freely combined from these three types of symbols to form multiple time slot formats.

[0159] like Figure 2d As shown in the example, the time slot type can be divided into four cases according to the time slot format defined by the protocol.

[0160] Case 1: Contains only the "D" symbol, often referred to as a downlink-only slot (DL-only slot).

[0161] Case 2: Contains only the "U" symbol, often referred to as a downlink-only slot (UL-only slot).

[0162] Case 3: Contains only the "F" symbol, often referred to as a flexible-only slot.

[0163] Case 4: A time slot contains at least one "D" or "U" symbol, and the time slot also contains an "F" symbol.

[0164] In addition, in such Figure 2d As shown, Case 4 can be further divided into several sub-cases.

[0165] Case 4-1: A time slot contains more "D" symbols and fewer "F" symbols.

[0166] Case 4-2: A time slot contains more "U" symbols and fewer "F" symbols.

[0167] Case 4-3: A time slot contains more "D" symbols, fewer "F" symbols, and fewer "U" symbols.

[0168] Case 4-4: A time slot contains more "U" symbols, fewer "F" symbols, and fewer "D" symbols.

[0169] Case 4-5: A time slot contains alternating "D" symbols, "F" symbols, and "U" symbols.

[0170] As the examples above demonstrate, 5G NR's slot format design allows for symbol-level changes in uplink and downlink data, whereas LTE typically only allows for subframe-level changes. This design is more flexible and also provides a wider variety of slot types to adapt to different service types in various scenarios.

[0171] 4. Self-contained time slots.

[0172] Figure 2d Case 4-3, Case 4-4, and Case 4-5 are also known as self-contained slots, which correspond to the three structures of self-contained slots.

[0173] One structure is a time slot primarily used for downlink (DL-dominant slot): that is... Figure 2d In Case 4-3, the time slot is mainly used for downlink data transmission, while a small number of symbols are time-division multiplexed to transmit uplink control signals (such as the hybrid automatic repeat request (HARQ) feedback of the downlink data) or sounding reference signals (SRS), thereby shortening the downlink HARQ feedback delay.

[0174] Another structure is a UL-dominant slot primarily used for uplink: that is... Figure 2d In Case 4-4, the time slot is mainly used for uplink data transmission, while a small number of symbols are used through time division multiplexing to transmit downlink control signals (such as uplink scheduling indications in PDCCH), thereby shortening the uplink scheduling delay.

[0175] Generally, in a self-contained time slot design, both network devices and terminal devices can switch between uplink and downlink transmission within a single time slot. By reserving a protection time and not transmitting or receiving any signals during the protection time, normal operation can be guaranteed after the switch.

[0176] 5. Mini-slot.

[0177] To further reduce air interface latency, the protocol introduces the concept of microslots, whose time domain length can be less than 14 symbols. Compared to basic time slot scheduling, microslot scheduling offers finer time domain division and shorter scheduling latency. Microslot scheduling is often referred to as non-slot-based scheduling.

[0178] 6. Frequency domain resources.

[0179] A resource element (RE) is the smallest granular physical layer resource in 5G NR, which is one subcarrier in the frequency domain and one OFDM symbol in the time domain.

[0180] A resource block (RB) is the basic unit of channel resource allocation in the frequency domain in 5G NR. An RB can contain 12 subcarriers. Since the subcarrier spacing in 5G NR is variable, the actual bandwidth of an RB is also variable.

[0181] A Resource Grid (RG) is a collection of time-frequency resources. In 5G NR, it is defined as follows: For each carrier and its different Numberology, an RG is a resource set of all subcarriers in the frequency domain and all symbols within one subframe in the time domain, with the starting point in the frequency domain at the granularity of RBs. Since different Numberologies correspond to different SCSs, and one RB contains 12 subcarriers, for the same transmission bandwidth, the number of RBs in an RG differs under different Numberologies. An RG in the time domain is one subframe. Furthermore, uplink and downlink each define their own RGs.

[0182] like Figure 2e The diagram shown illustrates one implementation of resource allocation for RE, RB, and RG. Figure 2e In this context, a subframe in the time domain can include several OFDM symbols; a resource element represents a resource with one subcarrier in the frequency domain and one OFDM symbol in the time domain; a resource block contains 12 subcarriers in the frequency domain; and a resource grid represents a set of time-frequency resources.

[0183] A common resource block (CRB) can be understood as a collective term for all resource blocks (RBs) in 5G NR. They are numbered starting from 0, and the center frequency point of subcarrier number 0 in CRB0 is point A.

[0184] A physical resource block (PRB) refers to the RBs contained in the bandwidth part (BWP) of a UE in 5G NR. They are also numbered starting from 0 and are the basic unit of data channel scheduling.

[0185] A resource block group (RBG) is a combination of several resource block blocks (PRBs) within a bandwidth portion (BWP). They are also numbered starting from 0 and are the basic unit of data channel scheduling. An RBG can contain {2, 4, 8, 16} PRBs, the specific number depending on the number of RBs in the BWP and the configuration options.

[0186] A resource element group (REG) is the basic unit of control channel resources. One REG is 12 subcarriers in the frequency domain, which is the width of one RB, and one OFDM symbol in the time domain.

[0187] The control channel element (CCE) is the basic unit for scheduling control channel resources. One CCE consists of 6 REGs in the frequency domain.

[0188] like Figure 2f The diagram shown illustrates the relationship between REG and CCE.

[0189] The above defines the time-frequency resources for NR. Future networks may use the same or different definitions. For example, future networks may define multiple subcarrier spacings, not limited to the SCS in 5G. A time slot can include one or more symbols, and an RB can include one or more subcarriers, etc.

[0190] 7. Sending or receiving

[0191] The Physical Reception Link Control Channel (PRxCCH) is a physical layer control channel. Generally, standard protocols describe it from the perspective of the terminal device; it's the physical layer control channel received by the terminal device, similar in function to the PDCCH in LTE and 5G. PRxCCH may be a new physical layer control channel introduced in next-generation communication systems (such as 6G). However, 6G may still use PDCCH to represent the physical downlink control channel or physical transmit link control channel of the terminal device.

[0192] The Physical Reception Link Shared Channel (PRxSCH) is a physical layer data channel. Generally, standard protocols describe it from the perspective of the terminal device; it's the physical layer data channel received by the terminal device, similar in function to the PDSCH in LTE and 5G. PRxSCH may be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PDSCH to represent the physical downlink data channel or physical receive link data channel of the terminal device.

[0193] The Physical Transmission Link Control Channel (PTxCCH) is a physical layer control channel. Generally, standard protocols describe it from the perspective of the terminal device; it's the physical layer control channel transmitted by the terminal device, similar in function to the PUCCH in LTE and 5G. PTxCCH may be a new physical layer control channel introduced in 6G. Of course, future communications such as 6G may still use PUCCH to represent the physical uplink control channel or physical transmission link control channel of the terminal device.

[0194] The Physical Transmission Link Shared Channel (PTxSCH) is a physical layer data channel. Generally, standard protocols describe it from the perspective of the terminal device; it's the physical layer data channel transmitted by the terminal device, similar in function to PUSCH in LTE and 5G. PTxSCH may be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PUSCH to represent the physical uplink data channel or physical receive link data channel of the terminal device.

[0195] Optionally, from the perspective of the terminal device, downlink can be described as receiving; and from the perspective of the terminal device, uplink can be described as sending.

[0196] Currently, during communication between different devices, the signal transmitter can send a measurement signal (e.g., a reference signal), and the corresponding signal receiver can receive this measurement signal and perform measurements based on it to obtain channel-related information (e.g., channel interference information). This channel-related information can then be used for resource management. However, improving measurement performance during this process remains a pressing technical challenge.

[0197] In some implementation examples, network devices can be configured with NZP CSI-RS resource measurement channels and ZP CSI-RS measurement interference, where ZP CSI-RS resources can also be referred to as CSI-IM resources.

[0198] like Figure 2g The example shown is a schematic diagram of CSI-IM resources in an LTE system. Figure 2g In the diagram, each box represents one RE (Resource Provider). Two symbols in the time domain and 12 subcarriers represent 24 REs. Taking CSI-IM resource transmission with 4 ports of CSI-RS as an example, this is the LTE CSI-IM pattern shown in the diagram. In the time domain, CSI-IM resources include two symbols in the time domain; in the frequency domain, CSI-IM resources include two subcarriers in the frequency domain; CSI-IM resources occupy 4 of the 24 REs (i.e., the 4 REs corresponding to the black-filled boxes).

[0199] like Figure 2h The example shown is a schematic diagram of CSI-IM resources in an NR system. Figure 2h In the example of CSI-RS with 4 ports for CSI-IM resource transmission, the following two diagrams are included:

[0200] NR CSI-IM pattern 0: In the time domain, CSI-IM resources consist of two consecutive symbols in time; in the frequency domain, CSI-IM resources consist of two consecutive subcarriers in frequency; occupying 4 REs.

[0201] NR CSI-IM pattern 1: In the time domain, CSI-IM resources consist of 1 symbol in time; in the frequency domain, CSI-IM resources consist of 4 consecutive subcarriers in frequency; occupying 4 REs.

[0202] Generally, CSI-IM resources only measure interference power, which is considered when calculating CQI. During interference power calculation, the terminal device considers the four REs (e.g., REs in the CSI-IM pattern) to be present. Figure 2g or Figure 2h The received power of the four REs in the data is under the same channel interference, so they will be averaged.

[0203] Furthermore, the CSI-RS configuration can include consecutive frequency domain resources, such as the network device indicating the starting RB and the number of RBs. Within different RBs, the CSI-IM pattern is identical in each RB. During the above process, the terminal device will employ an interference measurement averaging method to perform interference measurements on different frequency domain resources configured for the CSI-IM resource. These different frequency domain resources can include different RBs, or different REs within a single RB (e.g., ...). Figure 2h (4 REs in the text).

[0204] However, in CSI-IM resources, the channel conditions corresponding to different frequency domain resources may be different, which leads to inaccurate interference measurements corresponding to the above interference measurement averaging method, thus affecting communication performance.

[0205] To address the aforementioned problems, this application provides a communication method and related apparatus, which will be described in detail below with reference to the accompanying drawings.

[0206] Please see Figure 3 This is a schematic diagram of an implementation of the communication method provided in this application, which includes the following steps.

[0207] It should be understood that in the following text, Figure 3 This application illustrates the method using a first communication device and a second communication device as examples of the execution subjects in the interactive illustration, but it does not limit the execution subjects of this interactive illustration. For example, the first communication device and / or the second communication device can be a communication device, or a chip, baseband chip, modem chip, SoC chip containing a modem core, SIP chip, communication module, chip system, processor, logic module, or software in the communication device. Optionally, the communication device can be a terminal device or a network device (e.g., the network device can be an access network device, access network element, etc.).

[0208] As an example, the first communication device can be a terminal device and the second communication device can be a network device, or both the first and second communication devices can be network devices. For example, the network device can be an access network device or a communication device in an ORAN system (e.g., at least one of CU, DU, RU).

[0209] As another example, both the first and second communication devices are terminal devices, i.e. Figure 3 The proposed solution can be applied to sidelink communication scenarios.

[0210] S301. The second communication device sends first information, and correspondingly, the first communication device receives the first information. The first information is used to configure first power information for interference measurement resources.

[0211] S302. The first communication device performs measurements based on interference measurement resources and first power information.

[0212] It should be understood that interference measurement resources can be resources used for interference measurement. For example, interference measurement resources can be Channel State Information Interference Measurement (CSI-IM) resources, or interference measurement resources can be other names specified in the standard / protocol, which are not limited here.

[0213] It should be understood that the first information is used to configure the first power information of the interference measurement resource, or it can be described as: the first information is used to indicate the first power information of the interference measurement resource, or the first information is used to determine the first power information of the interference measurement resource.

[0214] It should be understood that an interference measurement resource may include one or more resources, and the first power information of the interference measurement resource may be used to indicate (or determine) the power of the signal carried by the one or more resources included in the interference measurement resource. For example, the first power information may be used to indicate (or determine) the power of the signal carried by each resource included in the interference measurement resource.

[0215] Optionally, the first communication device may also receive configuration information for configuring interference measurement resources. This configuration information and the aforementioned first information may be carried in the same message / signaling / information; for example, the configuration information may include the aforementioned first information, or the aforementioned first information may include the configuration information. Alternatively, the configuration information and the aforementioned first information may be carried in different messages / signaling / information.

[0216] It should be noted that the process of the first communication device measuring based on the interference measurement resource and the first power information may include: the first communication device measuring the interference measurement resource based on the first power information to obtain interference measurement result information; and / or, after obtaining the interference measurement result information by measuring the interference measurement resource, the first communication device processing the interference measurement result information based on the first power information (e.g., mathematical operations, updates, or adjustments).

[0217] based on Figure 3 In the illustrated scheme, the first information received by the first communication device in step S301 is used to configure the first power information of the interference measurement resources. Subsequently, the first communication device can perform measurements based on the interference measurement resources and the first power information in step S302. In this way, the first communication device can measure the interference measurement resources based on the power information configured in the first information, which can improve the accuracy of interference measurement and thus enhance communication performance.

[0218] exist Figure 3In one possible implementation of the method shown, the first power information indicated by the first information in step S301 includes a power value and / or a power offset parameter, which is relative to a reference power. Therefore, the second communication device can configure the power of the interference measurement resource in various ways to improve the flexibility of the solution implementation.

[0219] Optionally, the first power information is used to indicate power parameters, wherein the power parameters may be power values ​​and / or power offset parameters.

[0220] Optionally, the power offset parameter can also be simply referred to as power offset.

[0221] Optionally, as described above, the interference measurement resource may include one or more resources. Accordingly, in the above scheme, the first power information may include the power values ​​of 0 or 1 or more resources included in the interference measurement resource, and / or, the first power information may include the power offset parameters of 0 or 1 or more resources included in the interference measurement resource.

[0222] exist Figure 3 In one possible implementation of the method shown, the interference measurement resource is used for interference measurement of a first wireless access technology, and the interference measurement resource is also used to carry the communication signal of a second wireless access technology (or, the interference measurement resource corresponds to the communication signal of the second wireless access technology). Specifically, in addition to being used for interference measurement of the first wireless access technology, the interference measurement resource can also be used to carry the communication signal of the second wireless access technology, enabling the above scheme to be applied to scenarios of spectrum sharing between two or more wireless access technologies (e.g., multiple wireless access technology spectrum sharing (MRSS)), improving the accuracy of interference measurement in such scenarios, and thus improving communication performance.

[0223] For example, the first wireless access technology can be a future network, including but not limited to 6G, 5.5G, and next-generation networks of 5G. The second wireless access technology can be NR / 5G / 5G NR, 4G, LTE, etc.

[0224] In one possible implementation, Figure 3 The method further includes: the first communication device receiving second information, the second information indicating or including information related to the reference power. In other words, the first communication device can also receive the second information and determine the reference power based on the second information, so that the first communication device can determine the power value of the signal carried by the interference measurement resource based on the reference power and the power offset parameter included in the first power information.

[0225] Optionally, the aforementioned reference power can be pre-configured to reduce transmission overhead.

[0226] Optionally, the reference power can be implemented in a variety of ways, which will be described below with some implementation examples.

[0227] For example, the reference power can be the power of the synchronization signal (SS), and correspondingly, the aforementioned power offset parameter can be the power offset relative to the synchronization signal (poweroffsetSS). Optionally, the SS can include the synchronization signal / physical broadcast channel block (SS / PBCH block, or SSB for short), the primary synchronization signal (PSS), the secondary synchronization signal (SSS), or other signals used for synchronization as specified in future standards / protocols.

[0228] For example, the reference power can be the power of the physical downlink shared channel (PDSCH), and correspondingly, the power offset parameter mentioned above can be the power offset relative to the PDSCH (poweroffsetPDSCH).

[0229] For example, the reference power can be the power of the control resource set (CORESET), and correspondingly, the power offset parameter mentioned above can be the power offset relative to CORESET (poweroffsetCORESET).

[0230] For example, the reference power can be the power of a certain frequency band, and correspondingly, the power offset parameter mentioned above can be the power offset relative to that frequency band.

[0231] For example, the reference power can be the power of a CSI-IM resource corresponding to a certain CSI-IM resource identifier, and correspondingly, the power offset parameter mentioned above can be the power offset relative to that CSI-IM resource.

[0232] Optionally, a CSI-IM resource corresponds to a frequency band, and the aforementioned power offset parameter can be a power offset parameter configured for the CSI-IM resource of that frequency band; for example, a frequency corresponding to a CSI-IM resource can be configured through CSI-IM resource configuration information, which can configure at least one of the following: starting RB, number of RBs, transmission power, and power offset parameter.

[0233] It should be noted that the resource type of the interference measurement resource corresponding to the first power information can be implemented in a variety of ways, which will be explained with some examples below.

[0234] Example 1: The interference measurement resource is a zero-power interference measurement resource.

[0235] In Example 1, the interference measurement resource that the first communication device measures in step S302 can be a zero-power interference measurement resource, that is, the interference measurement resource can not carry other signals, so that the interference measurement result information obtained by the first communication device can reflect the interference situation caused by the interference signal on the interference measurement resource.

[0236] Optionally, taking the first communication device as the terminal device and the second communication device as the network device as an example, in the zero-power interference measurement resource, the network device (e.g., serving cell or serving base station) does not transmit a signal, i.e., it is at zero power. This interference measurement resource can be used to measure the interference of signals transmitted by other network devices (e.g., other cells or other base stations).

[0237] Optionally, taking terminal device A as the first communication device and terminal device B as the second communication device as an example, in the zero-power interference measurement resource, terminal device B does not transmit a signal, i.e., it is at zero power. This interference measurement resource can be used to measure the interference of signals transmitted by network devices or other terminal devices.

[0238] Example 2: The interference measurement resource is a non-zero power interference measurement resource, and the first power information is used to determine at least two power information corresponding to the interference measurement resource.

[0239] In Example 2, the interference measurement resource that the first communication device measures in step S302 can be a non-zero power interference measurement resource, that is, the interference measurement resource can carry a non-zero power signal, so that the interference measurement result information obtained by the first communication device can reflect the interference situation caused by the non-zero power signal on the interference measurement resource.

[0240] Furthermore, when the interference measurement resource is a non-zero power interference measurement resource, the first communication device can determine at least two power information corresponding to the interference measurement resource based on the first power information. Compared to the method of averaging interference measurements on different resources, in the above scheme, the different resources included in the interference measurement resource can be configured with their own power information (for example, the interference measurement resource can correspond to at least two signals with different power), enabling the first communication device to perform measurements based on the corresponding power information of each resource and obtain interference measurement results, thereby further improving the accuracy of the measurement.

[0241] Optionally, for interference measurement resources with non-zero power, network devices (e.g., serving cells or serving base stations) determine, through configuration or pre-configuration, that there may or may not be a transmission of non-zero power signals on such resources. That is, the power value indicated by the power information corresponding to the non-zero power interference measurement resource may be 0 or not. This non-zero power signal may originate from the network device itself, from other network devices (e.g., other cells or other base stations), or from one or more terminal devices.

[0242] Optionally, the interference measurement resources include zero-power interference measurement resources and non-zero-power interference measurement resources, that is, the above Example 1 and Example 2 can be implemented together.

[0243] For example, as mentioned above, interference measurement resources may include one or more resources. When such interference measurement resources include zero-power interference measurement resources, the first power information may indicate the power of the zero-power interference measurement resource. For example, the interference measurement resource may include a zero-power channel state information reference signal (ZP CSI-RS) resource.

[0244] For example, if the interference measurement resource includes a non-zero power interference measurement resource, the first power information can indicate the power of the non-zero power interference measurement resource. For instance, the interference measurement resource may include a non-zero power channel state information reference signal (NZP CSI-RS) resource.

[0245] It should be noted that the resources included in the above interference measurement resources can be implemented in various ways, which will be described below with some implementation examples.

[0246] Example A: The interference measurement resources include N frequency domain resources, where N is a positive integer; wherein, the first power information is used to determine the power information corresponding to the N frequency domain resources.

[0247] In Example A, the aforementioned interference measurement resources may include N frequency domain resources, enabling the first communication device to determine the power information corresponding to the N frequency domain resources based on the first power information, and to perform measurements based on the power information corresponding to the N frequency domain resources, thereby improving the accuracy of interference measurement of the N frequency domain resources.

[0248] Optionally, N is greater than 1, and the power information corresponding to different frequency domain resources among the N frequency domain resources can be the same or different. For example, the first communication device can determine the N power information corresponding to the N frequency domain resources based on the first power information, and can measure the N frequency domain resources based on the N power information. Compared with the method of averaging interference measurements on different frequency domain resources, the first communication device can measure based on the corresponding power information of each frequency domain resource and obtain the interference measurement result, which can further improve the accuracy of the measurement.

[0249] Optionally, a frequency domain resource may include one or more frequency domain units. A frequency domain unit can be a unit for scheduling or configuring communication resources in the frequency domain.

[0250] Optionally, a frequency domain unit may indicate one or more resources in the frequency domain, including one or more subcarriers, one or more subcarrier groups, one or more resource blocks, one or more physical resource blocks, one or more resource block groups, one or more partial bandwidths, or other implementations specified by standards / protocols.

[0251] For example, a frequency domain element can be a resource block. A resource block can include one or more subcarriers, such as 12.

[0252] Optionally, the first power information includes N power information items, which correspond to N frequency domain resources of the interference measurement resource. For example, the N power information items correspond one-to-one with the N frequency domain resources included in the interference measurement resource. Alternatively, the i-th power information item among the N power information items corresponds to the i-th frequency domain resource among the N frequency domain resources included in the interference measurement resource, where i takes values ​​from 1 to N.

[0253] Optionally, the interference measurement resources include N frequency domain resources, and the first power information includes N power information corresponding to each of the N frequency domain resources. For example, the N frequency domain resources correspond one-to-one with the N power information. Alternatively, the i-th frequency domain resource in the N frequency domain resources corresponds to the i-th power information in the N power information, where i takes values ​​from 1 to N.

[0254] Optionally, the above N frequency domain resources can be replaced with N frequency bands.

[0255] For example, the interference measurement resource includes at least two frequency bands, and the first power information can indicate the power information of the at least two frequency bands.

[0256] For example, the first power information can be obtained in at least one of the following ways:

[0257] In Method A, the resource configuration information for interference measurement resources can be configured as follows: the starting frequency domain unit, the number of frequency domain units in frequency band 1, and the number of frequency domain units in frequency band 2. The first power information can be configured as the power value for frequency band 1 and the power value for frequency band 2. The power value can refer to the signal transmission power.

[0258] In Method B, the resource configuration information for interference measurement resources can be configured as follows: the starting frequency domain unit of the interference measurement resource, the number of frequency domain units in band 1, and the number of frequency domain units in band 2; the first power information can be configured as the power offset parameters of band 1 and band 2.

[0259] In method C, the resource configuration information of the interference measurement resource can be configured as the starting frequency domain unit of the interference measurement resource, the number of frequency domain units in frequency band 1, and the number of frequency domain units in frequency band 2; the first power information can be configured as the power offset parameter of frequency band 2 relative to frequency band 1, or the first power information can be configured as the power offset parameter of frequency band 1 relative to frequency band 2.

[0260] Optionally, the first information is used to configure N1 power information corresponding to an interference measurement resource, where N1 is an integer greater than or equal to 1. For example, the N1 power information corresponds to N1 frequency domain resources of the interference measurement resource.

[0261] For example, interference measurement resources include two frequency domain resources.

[0262] For example, the first information includes two power information items. The first power information item corresponds to the first frequency domain resource of the interference measurement resource, and the second power information item corresponds to the second frequency domain resource of the interference measurement resource.

[0263] For example, the interference measurement resource includes three frequency domain resources, the reference power is the power of the first frequency domain resource, and the first information includes two power information items. Specifically, the first power information item is the power offset parameter of the second frequency domain resource of the interference measurement resource relative to the reference power, and the second power information item is the power offset parameter of the third frequency domain resource of the interference measurement resource relative to the reference power.

[0264] For example, the interference measurement resource includes two frequency domain resources. The reference power is the power of the first frequency domain resource, and the first information includes one power information. This power information is the power offset parameter of the second frequency domain resource relative to the reference power.

[0265] In one possible implementation of Example A, a frequency domain cell of the i-th frequency domain resource of the N frequency domain resources includes M resource cells, where i is from 1 to N and M is an integer greater than or equal to 1; wherein, the first power information is used to determine the power information corresponding to the M resource cells.

[0266] For example, any frequency domain resource (i.e., the i-th frequency domain resource) among N frequency domain resources may contain a number of resource units (i.e., M resource units). The first communication device determines the power information corresponding to the number of resource units based on the first power information, and performs finer-grained measurement based on the power information corresponding to each resource unit, which can further improve the accuracy of the measurement.

[0267] Optionally, a resource unit can be the smallest unit of time-frequency resources. For example, a resource unit can be a resource of one symbol in the time domain and one subcarrier in the frequency domain. For instance, a resource unit can be a resource element (RE), which can reside in one or more resource grids (RGs). Alternatively, a resource unit can also be other implementations specified by standards / protocols. The following example uses an RE as the resource unit.

[0268] For example, a frequency domain element can be a resource block. A resource block can include one or more subcarriers, such as 12.

[0269] For example, a resource block of the i-th frequency domain resource of the N frequency domain resources includes M resource units, where i is from 1 to N and M is an integer greater than or equal to 1; wherein, the first power information is used to determine the power information corresponding to the M resource units.

[0270] In one possible implementation of Example A, the first power information satisfies at least one of the following methods one through four.

[0271] Method 1: The first power information includes first indication information and / or second indication information. The first indication information is used to indicate the resource pattern of the M REs, and the second indication information is used to indicate the power information corresponding to the resource pattern of the M REs.

[0272] It should be understood that in Method 1, the first indication information or the second indication information can be pre-configured or predefined by the protocol; that is, the first power information may include one of the first indication information and the second indication information. The following example illustrates that the first power information includes both the first and second indication information.

[0273] Furthermore, the one or more resource patterns corresponding to the interference measurement resources can be pre-configured or predefined by the protocol. Accordingly, the first indication information can indicate the identifier or index of the resource pattern of the M REs in the one or more resource patterns.

[0274] For example, a resource pattern can be a resource pattern within a frequency domain cell. For instance, a frequency domain cell can be considered a resource block. This paper uses an example of a resource block comprising 12 subcarriers for illustration.

[0275] Optionally, the resource map of the interference measurement resource may include at least one of the following:

[0276] like Figure 4a The resource map of the interference measurement resource includes... Figure 4a The resource units of symbols b and c are shown in the figure. Optionally, the positions of symbols b and c can be non-adjacent or arbitrary. This application does not limit this; the illustration is merely an example.

[0277] Resource pattern a1: The RE of symbol b corresponds to the first channel, and the RE of symbol c corresponds to the second channel;

[0278] Resource pattern a2: The RE of symbol b corresponds to the first channel, and the RE of symbol c corresponds to the third channel;

[0279] Resource pattern a3: The RE of symbol b corresponds to the second channel, and the RE of symbol c corresponds to the first channel;

[0280] Resource pattern a4: The RE of symbol b corresponds to the second channel, and the RE of symbol c corresponds to the third channel;

[0281] Resource pattern a5: The RE of symbol b corresponds to the third channel, and the RE of symbol c corresponds to the first channel;

[0282] Resource pattern a6: The RE of symbol b corresponds to the third channel, and the RE of symbol c corresponds to the second channel;

[0283] Resource pattern a7: The RE of symbol b and the RE of symbol c correspond to the first channel;

[0284] Resource pattern a8: The RE of symbol b and the RE of symbol c correspond to the second channel;

[0285] Resource pattern a9: The RE of symbol b and the RE of symbol c correspond to the third channel.

[0286] Optionally, one or more REs correspond to a certain channel (e.g., the RE of symbol b corresponds to the first channel, the RE of symbol c corresponds to the second channel, etc.). This can be understood as the one or more REs being a resource for the channel, or the one or more REs being used to carry the channel, or the one or more REs being used to measure the interference situation of the channel, or the one or more REs being used to measure the channel state information of the channel, etc.

[0287] like Figure 4b The resource pattern of the interference measurement resources includes resource elements RE1, RE2, RE3, and RE4. Optionally, the positions of RE1, RE2, RE3, and RE4 can be non-adjacent or arbitrary RE positions. This application does not limit this; the illustration is merely an example.

[0288] Resource pattern b1: RE1 and RE2 correspond to the first channel, and RE3 and RE4 correspond to the second channel;

[0289] Resource pattern b2: RE1 and RE2 correspond to the first channel, and RE3 and RE4 correspond to the third channel;

[0290] Resource pattern b3: RE1 and RE2 correspond to the second channel, and RE3 and RE4 correspond to the first channel;

[0291] Resource pattern b4: RE1 and RE2 correspond to the second channel, and RE3 and RE4 correspond to the third channel;

[0292] Resource pattern b5: RE1 and RE2 correspond to the third channel, and RE3 and RE4 correspond to the first channel;

[0293] Resource pattern b6: RE1 and RE2 correspond to the third channel, and RE3 and RE4 correspond to the second channel;

[0294] Resource pattern b7: RE1, RE2, RE3, and RE4 correspond to the first channel;

[0295] Resource pattern b8: RE1, RE2, RE3, and RE4 correspond to the second channel;

[0296] Resource pattern b9: RE1, RE2, RE3 and RE4 correspond to the third channel.

[0297] Here, a1 to a9 and b1 to b9 are identifiers or indices of the resource patterns. For example, the values ​​of a1 to a9 and b1 to b9 can be integers greater than or equal to 0.

[0298] The first channel, the second channel, or the third channel may include at least one of the following: a synchronization channel, a common channel, a broadcast channel, a control channel, or a data channel.

[0299] Optionally, the first indication information may include the identifier or index of the resource pattern described above. The first communication device can determine the resource pattern based on the first indication information.

[0300] Optionally, at least one of the power information of the first channel, the power information of the second channel, or the power information of the third channel can be predefined by the protocol. In this mode, the first communication device can determine the power information corresponding to the M resource units based on the first indication information.

[0301] Optionally, the second communication device indicates to the first communication device at least one of the power information of the first channel, the power information of the second channel, or the power information of the third channel.

[0302] Optionally, the second indication information may include at least one of the power information of the first channel, the power information of the second channel, or the power information of the third channel. The first communication device can determine at least one of the power information of the first channel, the power information of the second channel, or the power information of the third channel based on the second indication information. In this mode, the first communication device can determine the power information corresponding to M resource units based on the first indication information and the second indication information.

[0303] Optionally, the resource patterns of the M REs can be predefined by the protocol, such as any one of resource patterns a1 to a9 and b1 to b9. The second indication information indicates the power information corresponding to the resource patterns of the M REs. In this mode, the first communication device can determine the power information corresponding to the M resource units based on the second indication information.

[0304] Optionally, the reference power can be the power of the first channel, or the power of the second channel, or the power of the third channel.

[0305] For example, the second indication information may indicate at least one of the following: the power offset parameter of the first channel relative to the reference power, the power offset parameter of the second channel relative to the reference power, or the power offset parameter of the third channel relative to the reference power.

[0306] like Figure 4c As shown in the example below, different resource patterns correspond to different cases, and the identifier or index of the resource pattern is the case identifier (case ID). Figure 4c In this context, the resource pattern includes at least one of the following case IDs, from A to G.

[0307] Case A: The RE of the first symbol of the interference measurement resource corresponds to the SSB of the second radio access technology, and the RE of the second symbol corresponds to the PDSCH of the second radio access technology. Conversely, the RE of the second symbol of the interference measurement resource corresponds to the SSB of the second radio access technology, and the RE of the first symbol corresponds to the PDSCH of the second radio access technology. The latter case can be the same as the former case, or they can be different cases.

[0308] Case B: The RE of the first symbol of the interference measurement resource corresponds to the CORESET of the second radio access technology, and the RE of the second symbol corresponds to the PDSCH of the second radio access technology. Conversely, the RE of the second symbol of the interference measurement resource corresponds to the CORESET of the second radio access technology, and the RE of the first symbol corresponds to the PDSCH of the second radio access technology. The latter case can be the same as the former case, or they can be different cases.

[0309] Case C: The RE of the first symbol of the interference measurement resource corresponds to the CORESET of the second radio access technology, and the RE of the second symbol corresponds to the SSB of the second radio access technology. Conversely, the RE of the second symbol of the interference measurement resource corresponds to the CORESET of the second radio access technology, and the RE of the first symbol corresponds to the SSB of the second radio access technology. The latter case can be the same as the former case, or they can be different cases.

[0310] Case D: The RE of the first symbol of the interference measurement resource corresponds to the PDSCH of the second radio access technology, and the RE of the second symbol corresponds to the SSB of the second radio access technology. Conversely, the RE of the second symbol of the interference measurement resource corresponds to the PDSCH of the second radio access technology, and the RE of the first symbol corresponds to the SSB of the second radio access technology. The latter case can be the same as the former case, or they can be different cases.

[0311] Case E: The RE of the interference measurement resource corresponds to the SSB of the second radio access technology.

[0312] Case F: The RE of the interference measurement resource corresponds to the CORESET of the second radio access technology.

[0313] Case G: The RE of the interference measurement resource corresponds to the PDSCH of the second radio access technology.

[0314] In Method 1, the first communication device can obtain the first power information by receiving the first information in step S301. The first power information may include first indication information and second indication information. The first indication information may indicate the case ID corresponding to the resource pattern of the interference measurement resource (for example, the case ID is at least one of the case IDs A to G mentioned above), and the second indication information may indicate the power information corresponding to the case ID.

[0315] For example, the second communication device may configure one or more of the following to the first communication device: power information of the SSB of the second radio access technology, power information of the CORESET of the second radio access technology, and power information of the PDSCH of the second radio access technology. Thereafter, the first communication device can determine the power information of each RE included in the interference measurement resource based on the case ID corresponding to the case contained in the first power information. As described above, the power information may include power values ​​and / or power offset parameters.

[0316] For example, the second indication information included in the first power information can indicate that the power value of the SSB of the second wireless access technology is p11, the power value of the CORESET of the second wireless access technology is p12, and the power value of the PDSCH of the second wireless access technology is p13.

[0317] For example, the second indication information included in the first power information can indicate that the power offset parameter of the SSB of the second wireless access technology relative to the PDSCH of the second wireless access technology is delta1, and the power offset parameter of the CORESET of the second wireless access technology relative to the PDSCH of the second wireless access technology is delta2, etc.

[0318] In Method 1, the first communication device can perform measurements in step S302 based on interference measurement resources and first power information. Different measurement processes may correspond to different cases. The following description uses the second indication information included in the first power information indicating that the power offset parameter of the SSB of the second radio access technology relative to the PDSCH of the second radio access technology is delta1, and the power offset parameter of the CORESET of the second radio access technology relative to the PDSCH of the second radio access technology is delta2 as an example.

[0319] It should be noted that the power offset parameter can be represented by delta, offset, or other methods. The following explanation will use delta as an example.

[0320] Case A: For REs with 2 SSBs and 2 PDSCHs, the total power P of REs in this resource pattern satisfies:

[0321] P = 2 * p SSB +2*p PDSCH =2*p PDSCH *delta1+2*p PDSCH = (2 + 2 * delta1) * p PDSCH .

[0322] Where, p SSB p represents the transmit power of the SSB of the second wireless access technology. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0323] Case B: For REs with 2 cores and 2 PDSCHs, the total power P of REs in this resource pattern satisfies:

[0324] P = 2 * p coreset +2*p PDSCH =2*p PDSCH *delta2+2*pPDSCH = (2 + 2 * delta2) * p PDSCH .

[0325] Where, p CORESET p represents the transmit power of the second wireless access technology, CORESET. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0326] Case C: For REs with 2 cores and 2 SSBs (PSS), the total power P of REs in this resource pattern satisfies:

[0327] P = 2 * p coreset +2*p SSB =2*p PDSCH *delta2+2*p PDSCH *delta1=(2*delta2+2*delta1)*p PDSCH .

[0328] Where, p CORESET p represents the transmit power of the second wireless access technology, CORESET. SSB p represents the transmit power of the SSB of the second wireless access technology. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0329] Case D: For REs with 2 PDSCHs and 2 SSBs (PSS), the total power P of REs in this resource pattern satisfies:

[0330] P = 2 * p SSB +2*p PDSCH =2*p PDSCH *delta1+2*p PDSCH = (2 + 2 * delta1) * p PDSCH .

[0331] Where, p SSB p represents the transmit power of the SSB of the second wireless access technology. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0332] Case E: For REs with 4 SSBs (PBCH), the total power P of the REs in this resource pattern satisfies:

[0333] P = 4 * p SSB =4*p PDSCH *delta1=(4*delta1)*p PDSCH .

[0334] Where, p SSB p represents the transmit power of the SSB of the second wireless access technology. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0335] Case F: For REs with 4 cores, the total power P of REs in this resource pattern satisfies:

[0336] P = 4 * p coreset =4*p PDSCH *delta2=(4*delta2)*p PDSCH .

[0337] Where, p coreset p represents the transmit power of the second wireless access technology, CORESET. PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0338] Case G: For REs with 4 PDSCHs, the total power P of REs in this resource pattern satisfies:

[0339] P = 4 * p PDSCH .

[0340] Where, p PDSCH This indicates the transmit power of the PDSCH of the second wireless access technology.

[0341] Method 2: The first power information includes the power information of one or more time units corresponding to the M REs.

[0342] Optionally, the aforementioned time units can be frames, subframes, time slots, sub-time slots, symbols, symbol groups, etc.

[0343] For example, taking the aforementioned time unit as a symbol, in Method 2, the first power information can be the power information corresponding to the symbol. For instance, the interference measurement resources can include REs for S symbols (S is a positive integer). The first power information included in the first information can indicate the power information corresponding to the S symbols.

[0344] Optionally, the S symbols can correspond to one or more power information parameters. For example, the power offset parameter of the first symbol (e.g., symbol 1) is delta. 21 The power offset parameter for the second symbol (e.g., symbol 2) is delta. 22 wait.

[0345] Assume the average received power of the interference measurement resource of symbol 1 is p. 21 The average received power of the interference measurement resource of symbol 2 is p. 22The interference power of the interference measurement resource can include at least one of the following:

[0346] A) The total interference power is p 21 *delta 21 +p 22 *delta 22 ;

[0347] B) The interference power of symbol 1 is p 21 *delta 22 ;

[0348] C) The interference power of symbol 2 is p 22 *delta 22 ;

[0349] D) The average interference power is (p 21 *delta 21 +p 22 *delta 22 ) / 2.

[0350] For example, taking the aforementioned time unit as a symbol group, in Method 2, the first power information can be the power information corresponding to the symbol group. For instance, the interference measurement resources can include S1 (S1 is a positive integer) symbol groups of REs. The first power information included in the first information can indicate the power information corresponding to the S1 symbol groups.

[0351] Optionally, each of the S1 symbol groups can correspond to one or more power information sets. For example, the power offset parameter of the first symbol group (e.g., symbol group 1) is delta. 23 The power offset parameter for the second symbol group (e.g., symbol group 2) is delta. 24 wait.

[0352] Assume the average received power of the interference measurement resource for symbol group 1 is p. 23 The average received power of the interference measurement resources in symbol group 2 is p. 24 The interference power of the interference measurement resource can include at least one of the following:

[0353] A) The total interference power is p 23 *delta 23 +p 24 *delta 24 ;

[0354] B) The interference power of symbol group 1 is p 23 *delta 23 ;

[0355] C) The interference power of symbol group 2 is p 24*delta 24 ;

[0356] D) The average interference power is (p 23 *delta 23 +p 24 *delta 24 ) / 2.

[0357] For example, the first power information includes S power information corresponding to S (S is a positive integer) time units corresponding to the M resource units. Here, the M resource units correspond to the S time units, which can be understood as the time units occupied by the M resource units being the S time units; that is, each of the S time units includes at least one resource unit from the M resource units. Optionally, in any two different time units of the S time units, the number of resource units among the M resource units included can be the same or different; this is not limited here.

[0358] Different resource units within the same time unit may correspond to the same power information, and / or the power information of different resource units within the same time unit may be the same.

[0359] Optionally, the reference power can be the power of the i1th symbol, where i1 takes values ​​from 1 to S. The value of i1 can be predefined by the protocol or indicated by the second communication device via signaling. For example, i1 can be 1.

[0360] For example, the first power information may include at least one of the following: the power offset parameter of the j1th symbol relative to the reference power, where j1 takes a value from 1 to S.

[0361] Method 3: The first power information includes the power information corresponding to the M REs.

[0362] For example, in method three, the second communication device configures interference measurement resources for the first communication device, which include M (M is a positive integer) REs. The first power information included in the first information can indicate the power information corresponding to the M REs, where the M REs can correspond to one or more power information sets.

[0363] Optionally, the reference power can be the power of the i2th RE, where i2 takes a value from 1 to M. The value of i2 can be predefined by the protocol or indicated by the second communication device via signaling. For example, i2 could take a value of 1.

[0364] For example, the first power information may include at least one of the following: the power offset parameter of the j2th RE relative to the reference power, where j2 takes a value from 1 to M.

[0365] Method 4: The first power information includes the power information of one or more sets of REs corresponding to the M REs.

[0366] For example, in method four, the interference measurement resources include Y groups of REs (Y is a positive integer), and each group of REs corresponds to one power information. In other words, the first power information may include Y power information corresponding to the Y groups of REs, wherein different REs within the same group may correspond to the same power information, that is, the power values ​​corresponding to different REs within the same group may be the same.

[0367] For example, a set of REs may include one or more REs.

[0368] For example, the power offset parameter of the first group of REs is delta. 31 The power offset parameter of the second group of REs is delta. 32 Etc. Assume the average received power of the first group of REs is p. 31 The average received power of the second group of REs is p 32 The interference power of the interference measurement resource can include at least one of the following:

[0369] A) The total interference power is p 31 *delta 31 +p 32 *delta 32 ;

[0370] B) The interference power of the first group of REs is p 31 *delta 31 ;

[0371] C) The interference power of the second group of REs is p 32 *delta 32 ;

[0372] D) The average interference power is (p 31 *delta 31 +p 32 *delta 32 ) / 2.

[0373] For example, the first power information includes the power information of the Y groups of REs corresponding to the M resource units.

[0374] Within the same set of REs, the power information of different resource units is the same.

[0375] Optionally, the reference power can be the power of the i3th RE group, where i3 takes values ​​from 1 to Y. The value of i3 can be predefined by the protocol or indicated by the second communication device via signaling. For example, i3 can take the value 1.

[0376] For example, the first power information may include at least one of the following: the power offset parameter of the j3 group of REs relative to the reference power, wherein j3 takes a value from 1 to Y.

[0377] For example, Example A will be described below using CSI-IM resources as interference measurement resources, along with some possible implementation methods. In the following implementation, the CSI-IM resources include at least two frequency bands, and the first power information can configure the power parameters of these at least two frequency bands.

[0378] Method 1: The resource configuration information for CSI-IM resources can be configured to include the starting RB, the number of RBs in band 1, and the number of RBs in band 2; the first power information can be configured to include the power values ​​for band 1 and band 2. The power value can refer to the signal transmission power.

[0379] Method 2: The resource configuration information for CSI-IM resources can be configured with the starting RB, the number of RBs in band 1, and the number of RBs in band 2; the first power information can be configured with the power offset parameters for band 1 and band 2.

[0380] For example, in Method 2, the power offset parameter can be configured with reference to the power of the PDSCH.

[0381] For example, in Method 2, the power offset parameter can be configured with reference to the power of the SSB (e.g., SSS, or PBCH).

[0382] For example, in Method 2, the reference power corresponding to the power offset parameter can be communicated to the terminal device by the network device via message / signaling.

[0383] Optionally, the power value can be an integer ranging from -60 to 50 dBm. dBm is a logarithmic unit representing the absolute value of power, where "m" represents milliwatts (mW), and 0 dBm equals 1 milliwatt of power. Alternatively, if the power value is not configured, it can be set to 0 dB by default.

[0384] Optionally, the power offset parameter can be -3dB, 0dB, 3dB, 6dB, 8dB, -8dB, etc., for example, it can be an integer from -8 to 15. Alternatively, if the power offset parameter is not configured, it can be set to the default value of 0dB.

[0385] Example B: The interference measurement resource includes P REs in a frequency domain unit, where P is a positive integer; wherein the first power information is used to determine the power information corresponding to the P REs.

[0386] In Example B, the aforementioned interference measurement resources may include P REs, enabling the first communication device to determine the power information corresponding to the P REs based on the first power information, and to perform measurements based on the power information corresponding to the P REs, thereby improving the accuracy of interference measurement of the P REs.

[0387] Optionally, P is greater than 1, and the power information corresponding to different REs among the P REs can be the same or different. For example, the first communication device can determine the P power information corresponding to the P REs based on the first power information, and can measure the P REs based on the P power information; compared with the method of averaging interference measurements on different REs, the first communication device can measure based on the corresponding power information of each RE and obtain the interference measurement result, which can further improve the accuracy of the measurement.

[0388] In one possible implementation of Example B, the first power information satisfies at least one of Modes 5 to 8.

[0389] Method 5: The first power information includes third indication information and / or fourth indication information. The third indication information is used to indicate the resource pattern of the P REs, and the fourth indication information is used to indicate the power information corresponding to the resource pattern of the P REs.

[0390] It should be understood that Method 5 can refer to the implementation process shown in Method 1 above and achieve the corresponding technical effects, which will not be elaborated here.

[0391] Method 6: The first power information includes the power information of one or more time units corresponding to the P REs.

[0392] It should be understood that Method 6 can refer to the implementation process shown in Method 2 above and achieve the corresponding technical effects, which will not be elaborated here.

[0393] Method 7: The first power information includes the power information corresponding to the P REs.

[0394] It should be understood that Method 7 can refer to the implementation process shown in Method 3 above and achieve the corresponding technical effects, which will not be elaborated here.

[0395] Method 8: The first power information includes the power information of one or more sets of REs corresponding to the P REs.

[0396] It should be understood that Method 8 can refer to the implementation process shown in Method 4 above and achieve the corresponding technical effects, which will not be elaborated here.

[0397] For example, Example B will be described below using CSI-IM resources as the interference measurement resource, combined with some possible implementation methods. In the following implementation method, the CSI-IM resource includes P (P is greater than 1) REs, and the first power information can configure the power parameters of these P REs.

[0398] For example, a CSI-IM resource includes P REs, and each P RE corresponds to one or more power parameters.

[0399] For example, a CSI-IM resource may include REs on multiple symbols, i.e., P REs located on multiple symbols. These multiple symbols correspond to one or more power parameters. For instance, a CSI-IM resource may contain P REs located on two symbols, symbol 1 and symbol 2, where the REs on symbol 1 correspond to one or more power parameters, and the REs on symbol 2 correspond to one or more power parameters.

[0400] In one possible implementation, Figure 3 The method further includes: the first communication device sending third information, which indicates interference measurement result information, determined based on the interference measurement resource and the first power information. In other words, after the first communication device obtains the interference measurement result information based on the interference measurement resource and the first power information, the first communication device can also send third information indicating the interference measurement result information, enabling the recipient of the third information (e.g., the second communication device) to determine the interference measurement result corresponding to the interference measurement resource, so that the recipient can perform resource management based on the interference measurement result.

[0401] Optionally, the aforementioned resource management may include radio resource management (RRM), data transmission, etc. For example, the RRM may include one or more of the following: cell selection and reselection, power control, access control, handover management, load control, frequency allocation (e.g., carrier aggregation (CA) related configuration, including but not limited to activating and deactivating carrier aggregation, configuring aggregated carrier sets, allocating resource blocks, etc.), channel allocation, and interference management.

[0402] For example, data transmission may include determining one or more of the following: resources for data transmission, precoding, antenna ports, number of layers, modulation and coding scheme, code rate, and multi-user multiplexing strategy.

[0403] For example, the recipient of the third information can learn about the interference situation of the second wireless access technology on each channel through the third information (there may be a power offset between the interference on each channel).

[0404] For example, when the interference measurement resource includes N frequency bands, the first communication device can feed back channel state information for each of the N frequency bands separately. Similarly, when the interference measurement resource includes multiple symbols, the first communication device can feed back channel state information for each symbol separately. Furthermore, when the interference measurement resource includes multiple symbol groups, the first communication device can feed back channel state information for each symbol group separately. Also, when the interference measurement resource includes multiple REs, the first communication device can feed back channel state information for each RE separately. Finally, when the interference measurement resource includes multiple RE groups, the first communication device can feed back channel state information for each RE group separately.

[0405] For example, when the interference measurement resource includes N frequency bands, the first communication device can provide channel state information for at least one frequency band. Similarly, when the interference measurement resource includes multiple symbols, the first communication device can provide channel state information for at least one symbol. Furthermore, when the interference measurement resource includes multiple symbol groups, the first communication device can provide channel state information for at least one symbol group. Also, when the interference measurement resource includes multiple REs, the first communication device can provide channel state information for at least one RE. And again, when the interference measurement resource includes multiple RE groups, the first communication device can provide channel state information for at least one RE group.

[0406] Optionally, the first communication device may not send the third information. For example, if the first communication device determines that the interference indicated by the interference measurement result is below or equal to a threshold, it can silently allow the second communication device to understand that the interference is low, thereby reducing transmission overhead.

[0407] As an example, the aforementioned interference measurement result information includes signal quality information of the signal carried by the interference measurement resource, and / or, channel state information (CSI).

[0408] Optionally, the above signal quality information may include one or more of the following: reference signal received power (RSRP), interference measurement reference signal received power (IM-RSRP), signal-to-interference plus-noise ratio (SINR), and signal-to-noise ratio (SNR).

[0409] Optionally, the CSI mentioned above may include one or more of the following: Channel Quality Information (CQI), RSRP, Received Reference Signal Quality (RSRQ), Received Signal Strength Indicator (RSSI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), or Layer Indicator (LI).

[0410] For example, the interference measurement results mentioned above may include power-related information, such as RSRP, IM-RSRP, etc. Taking IM-RSRP as an example, the power corresponding to IM-RSRP may include at least one of the following: the total interference power of the interference measurement resource, the average interference power of the interference measurement resource, the interference power corresponding to a certain frequency band, the interference power corresponding to a certain symbol, the interference power corresponding to a certain RE group, or the interference power corresponding to a certain RE.

[0411] Optionally, the type of power corresponding to the interference measurement result information reported by the first communication device can be predefined by the protocol, or it can be informed to the first communication device by the second communication device through higher-layer signaling or physical-layer signaling. This application does not limit this.

[0412] The power type corresponding to the interference measurement result information may include at least one of the following: total interference power of the interference measurement resource, average interference power of the interference measurement resource, interference power corresponding to a certain frequency band, interference power corresponding to a certain symbol, interference power corresponding to a certain RE group, or interference power corresponding to a certain RE.

[0413] Optionally, the type of power corresponding to the interference measurement result information can be understood as: the calculation method of the power corresponding to the interference measurement result information, or the reporting method, etc.

[0414] Optionally, the aforementioned interference measurement result information includes at least one of the following: an index of the signal carried by the interference measurement resource, an index of the interference measurement resource, an index of the reference signal corresponding to the interference measurement result information, or a resource index corresponding to the interference measurement result information. Therefore, the interference measurement result information may include at least one of the above indexes, enabling the recipient of the third information to determine the measurement object (i.e., resource and / or signal) corresponding to the interference measurement result information based on the at least one index, thereby obtaining the interference situation corresponding to the measurement object.

[0415] In the above process, the CQI can be selected by the receiver based on the measured signal-to-noise ratio (SNR) or signal-to-interference-plus-noise ratio (SINR). For example, the CQI value can be selected from a predefined table that maps SINR / SNR values ​​to CQI indices. This mapping is based on the assumption that a higher SINR / SNR value indicates better channel conditions, allowing for a higher data rate. The CQI can also be selected based on the current channel conditions and the target block error rate (BLER) using a predefined mapping table.

[0416] Optionally, SINR is a key metric for measuring signal quality, especially in wireless communication systems. For example, SINR satisfies:

[0417]

[0418] Among them, P s It is the power of the received signal, P i It is the power of the interference signal, P n It is the noise power at the receiving end.

[0419] As an example, the aforementioned interference measurement result information may include RSRP, where the RSRP of the interference measurement resource can be simply referred to as the RSRP of the interference measurement, i.e., IM-RSRP. Optionally, IM-RSRP reporting can be periodic, semi-persistent, or non-periodic.

[0420] For example, the second communication device can configure CSI-IM resources for the first communication device, and can report IM-RSRP for these CSI-IM resources. The second communication device can configure reporting parameters, including IM-RSRP, in the reporting configuration of these CSI-IM resources.

[0421] For example, the second communication device can configure CSI-RS resources for the first communication device, and can report IM-RSRP for these CSI-RS resources. The second communication device can configure reporting parameters, including IM-RSRP, in the reporting configuration of these CSI-RS resources.

[0422] As another example, the interference measurement results information mentioned above may include CQI or SINR.

[0423] CQI can be used to reflect interference conditions. For example, the SINR calculation formula mentioned above includes interference information.

[0424] Optionally, CSI-IM resources can be included in the configuration of relevant measurement resources reported by CQI.

[0425] Optionally, the CQI included in the interference measurement results information can be the value after SINR quantization.

[0426] In one possible implementation, before the first communication device sends the third information, the second communication device may instruct the first communication device whether to report the interference measurement results. For example, the second communication device may instruct whether to report the interference measurement results in its reporting configuration.

[0427] As an example, consider CSI-IM resources as interference measurement resources. The second communication device can configure one or more CSI-IM resources for the first communication device. Correspondingly, when the first communication device reports channel state information via third information, it can report the identifier of the CSI-IM resource (e.g., CSI-IM resource ID) and the corresponding IM-RSRP.

[0428] Optionally, the second communication device can configure the first communication device to report the number of interference measurement results (such as IM-RSRP), and / or indicate the threshold for the reported interference measurement results.

[0429] For example, the first communication device can prioritize reporting the CSI-IM resource ID with the highest interference measurement result (e.g., IM-RSRP) value, along with the corresponding interference measurement result (e.g., IM-RSRP), based on the number of reported values. Compared to reporting the interference measurement result (e.g., IM-RSRP) for each CSI-IM resource, this method can reduce reporting overhead.

[0430] For example, the first communication device can determine the interference measurement results (such as IM-RSRP) corresponding to interference measurement resources (such as CSI-IM resource) that are reported above the threshold based on the reported threshold.

[0431] For example, the first communication device reports the bitmap corresponding to the CSI-IM resource ID, where 1 represents a value greater than the threshold and 0 represents a value less than the threshold. For CSI-IM resources exceeding the threshold, IM-RSRP can be further fed back. Compared to reporting IM-RSRP for every CSI-IM resource, this method reduces reporting overhead.

[0432] Optionally, when the first communication device reports interference measurement results (such as IM-RSRP), it may consider quantizing the interference measurement results (such as IM-RSRP). For example, the number of quantization bits is Z bits, where Z is a positive integer. For example, Z can be 4 or 7.

[0433] For example, when Z is 7, the reporting range of interference measurement results (such as IM-RSRP) can be 0 to 127, a total of 128 values. A reported value of 0 means SINR < -23dB, and a reported value of 127 means SINR > 40dB. The accuracy of the measurement report is 0.5dB.

[0434] Optionally, the first communication device may report interference measurements based on a threshold differential (e.g., IM-RSRP). The reported offset is relative to the threshold.

[0435] Optionally, the first communication device can perform differential reporting between multiple interference measurement resources (such as CSI-IM resources).

[0436] For example, the first communication device reports the first interference measurement result (e.g., the first IM-RSRP) of the first interference measurement resource (e.g., the first CSI-IM resource), and the interference measurement result (e.g., the IM-RSRP) of the second interference measurement resource (e.g., the second CSI-IM resource) is reported differentially, that is, the reported value (second IM-RSRP) of the interference measurement result (e.g., the second IM-RSRP) of the second interference measurement resource (e.g., the second CSI-IM resource) is the power offset relative to the first interference measurement result (e.g., the first IM-RSRP).

[0437] like Figure 4d The example shown is a schematic diagram of one implementation of the signal of the second wireless access technology. Correspondingly, the interference measurement resources (denoted as CSI-IM resources) corresponding to the first wireless access technology can be used to measure the interference of the signal of the second wireless access technology. It should be understood that the CSI-IM resources may include... Figure 4b The frequency band shown can be any one of the three frequency bands 0, 1, and 2, or it can include any two or three of these three frequency bands.

[0438] 1) CSI-IM resources include frequency band 0 and frequency band 1. The average received power of CSI-IM resources in frequency band 0 (e.g., PDSCH, where the interfering signal is a second radio access technology) is p1, and the power offset parameter is delta1. The average received power of CSI-IM resources in frequency band 1 (e.g., SSB) is p2, and the power offset parameter is delta2. Then, the first communication device can determine at least one of the following interference powers:

[0439] A) Total interference power p1*delta1+p2*delta2;

[0440] B) Interference power of band 0: p1*delta1;

[0441] C) Interference power of band 1: p2*delta2;

[0442] D) The average interference power is (p1*delta1+p2*delta2) / 2.

[0443] 2) CSI-IM resources include frequency band 0 and frequency band 1. The average received power of CSI-IM resources in frequency band 0 (e.g., PDSCH, where the interfering signal is a second radio access technology) is p1, and the average received power of CSI-IM resources in frequency band 1 (e.g., SSB) is p2. With a power offset parameter of delta1, the first communication device can determine at least one of the following interference powers:

[0444] A) Total interference power p1 + p2 * delta2;

[0445] B) Interference power p1 in band 0;

[0446] C) Interference power of band 1: p2*delta1;

[0447] D) The average interference power is (p1+p2*delta1) / 2.

[0448] 3) CSI-IM resources include frequency band 1 and frequency band 0. The average received power of CSI-IM resources in frequency band 1 (e.g., PDSCH, where the interfering signal is a second radio access technology) is p1, and the average received power of CSI-IM resources in frequency band 0 (e.g., CORESET) is p3. The power offset parameter is delta2. Then, the first communication device can determine at least one of the following interference powers:

[0449] A) Total interference power p1 + p3 * delta2;

[0450] B) Interference power p1 in band 0;

[0451] C) Interference power of band 1: p3*delta2;

[0452] D) The average interference power is (p1+p3*delta2) / 2

[0453] 4) CSI-IM resources include frequency band 1 and frequency band 2. The average received power of CSI-IM resources in frequency band 1 (e.g., the interfering signal is an SSB of the second radio access technology) is p2, and the power offset parameter is delta1. The average received power of CSI-IM (CORESET) in frequency band 2 is p3, and the power offset parameter is delta2. Then, the first communication device can determine at least one of the following interference powers:

[0454] A) Total interference power p2*delta1+p3*delta2;

[0455] B) Interference power of band 1: p2*delta1;

[0456] C) Interference power of band 2: p3*delta2;

[0457] D) The average interference power is (p2*delta1+p3*delta2) / 2

[0458] 5) CSI-IM resources include frequency band 0, frequency band 1, and frequency band 2. The average received power of CSI-IM in frequency band 1 is p1, the average received power of CSI-IM in frequency band 2 is p2, the power offset parameter is delta1, and the average received interference power of CSI-IM in frequency band 3 is p3, the power offset parameter is delta2. Then, the first communication device can determine at least one of the following interference powers:

[0459] A) Total interference power p1 + p2 * delta1 + p3 * delta2;

[0460] B) Interference power p1 in band 0;

[0461] C) Interference power of band 1: p2*delta1;

[0462] D) Interference power of band 1: p3*delta2;

[0463] E) The average interference power is (p1+p2*delta1+p3*delta2) / 3

[0464] 6) CSI-IM resources include frequency band 1. If the average received power of CSI-IM (e.g., SSB) in frequency band 1 is p2 and the power offset parameter is delta2, then the first communication device can determine at least one of the following interference powers:

[0465] A) Total interference power p2*delta2;

[0466] B) Interference power of band 1: p2*delta2;

[0467] C) The average interference power is p2*delta2.

[0468] For example, when the power parameter configured in the power information is a power offset parameter (such as power offset or delta), the interference power of PDSCH is used as the reference power as above. Similarly, the interference power of SSB / CORESET can also be used as the reference power. This application does not limit this.

[0469] Please see Figure 5 This application provides a communication device 500, which can implement the functions of the first communication device (or second communication device) in the above method embodiments, and therefore can also achieve the beneficial effects of the above method embodiments. In this application embodiment, the communication device 500 can be the first communication device (or the second communication device), or it can be an integrated circuit or component inside the first communication device (or the second communication device), such as a chip, baseband chip, modem chip, SoC chip (e.g., an SoC chip containing a modem core), SIP chip, communication module, chip system, processor, etc.
