Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202411930056.7, filed with the State Intellectual Property Office of China on December 23, 2024, entitled "Communication Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and communication device. Background Technology

[0003] In wireless communication systems, terminal devices can measure channel information and trigger the reporting of measurement reports based on the measured channel information. In some schemes, network devices configure reporting conditions for terminal devices; when the reporting conditions are met, the terminal device sends a measurement report. However, the above-mentioned measurement report reporting schemes have only one reporting condition and are not flexible enough. Summary of the Invention

[0004] This application provides a communication method and communication device that can improve the flexibility of measurement report submission.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, a communication method is provided. This communication method includes: a first communication device receiving first information, wherein the first information is used to determine measurement reporting trigger conditions corresponding to K types of frequency domain resources, the frequency domain resource type being related to the operator corresponding to the frequency domain resource and / or whether it is an anchor frequency domain resource, and K being a positive integer. The first communication device determines whether to report a measurement report based on the first measurement reporting trigger conditions corresponding to the frequency domain resource type of the first frequency domain resource. Based on the communication method provided in the first aspect, the first communication device can receive the first information to obtain the measurement reporting trigger conditions corresponding to the K types of frequency domain resources, and determine whether to report a measurement report based on the resource type of the first frequency domain resource. This ensures that whether to report a measurement report matches the frequency domain resource type of the first frequency domain resource, thereby improving the flexibility of measurement report reporting.

[0007] As an example, the first communication device may be a terminal device, a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts may be used in the terminal device.

[0008] In some examples, the frequency domain resource type is associated with a Public Land Network (PLMN). A PLMN can be an actual PLMN or a virtual PLMN corresponding to multiple PLMNs.

[0009] In one possible implementation, the measurement report is used for at least one of the following: cell handover, radio link management, radio resource management, radio link recovery, or radio link failure determination. This allows for the implementation of various resource management functions.

[0010] In one possible implementation, the first measurement reporting trigger condition includes at least one of the following: the channel quality corresponding to the first frequency domain resource is greater than or equal to a first threshold; or, the channel quality corresponding to the first frequency domain resource is less than or equal to a second threshold; or, the channel quality corresponding to the second frequency domain resource is greater than or equal to the channel quality corresponding to the first frequency domain resource, and the difference between the channel quality corresponding to the second frequency domain resource and the channel quality corresponding to the first frequency domain resource is greater than or equal to a third threshold; or, the channel quality corresponding to the second frequency domain resource is greater than or equal to a fourth threshold; or, the channel quality corresponding to the first frequency domain resource is less than or equal to a fifth threshold, and the channel quality corresponding to the second frequency domain resource is greater than or equal to a sixth threshold. Wherein, the second frequency domain resource and the first frequency domain resource are located in the same frequency band, and the second frequency domain resource and the first frequency domain resource correspond to different network devices or cells; or, the frequency band where the second frequency domain resource is located is different from the frequency band where the first frequency domain resource is located. Thus, different measurement reporting trigger conditions can be matched according to one or more of the scenarios, requirements, or events, making measurement report reporting more flexible.

[0011] In one possible implementation, the first information indicates K sets of parameters. The k-th set of parameters in the K sets is used to determine the measurement reporting trigger condition corresponding to the k-th frequency domain resource type among the K frequency domain resource types, where k is a positive integer less than or equal to K. Thus, by indicating K sets of parameters with the first information, different parameters can be configured for different frequency domain resource types, achieving flexibility in measurement reporting and reducing the processing complexity of the first communication device.

[0012] Optionally, at least one set of parameters in the K sets corresponds to a frequency domain resource group or set of frequency domain resources. When at least one set of parameters in the K sets corresponds to a frequency domain resource group, the K sets of parameters can be configured according to the distribution of frequency domain resources, providing greater flexibility. A set of parameters can be configured for a frequency domain resource set, and this set of parameters can be applied to one or more frequency domain resources within the set, reducing signaling indication overhead.

[0013] In one possible implementation, the first information indicates the parameters corresponding to the i-th frequency domain resource type among K frequency domain resource types, as well as parameter information used to determine the measurement reporting trigger condition corresponding to at least one frequency domain resource type other than the i-th frequency domain resource type. The parameters corresponding to the i-th frequency domain resource type are used to determine the measurement reporting trigger condition corresponding to the i-th frequency domain resource type, where i is a positive integer less than or equal to K. Thus, the first information indicates the parameter information for the measurement reporting trigger condition corresponding to at least one frequency domain resource type other than the i-th frequency domain resource type. If an offset is applied, the amount of data in the first information can be reduced, thereby reducing the indication overhead.

[0014] Optionally, parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource group or set; and / or, parameter information for the measurement reporting trigger condition corresponding to at least one frequency domain resource type corresponds to a frequency domain resource group or set. Thus, when parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource group, K groups of parameters can be configured according to the distribution of frequency domain resources, providing greater flexibility in configuration. When parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource set, parameters or parameter information can be configured for a frequency domain resource set. These parameters or parameter information can be applied to one or more frequency domain resources within the set, reducing signaling indication overhead.

[0015] In one possible implementation, the measurement reporting trigger condition is related to the priority of the frequency domain resource type. Thus, the measurement reporting trigger condition can be determined based on the priority of the frequency domain resource type, enabling priority-based measurement reporting and meeting the measurement reporting needs of different scenarios and / or events.

[0016] In one possible implementation, the priority of the frequency domain resource type is related to at least one of the following: the characteristics of the first communication device, the requirements of the first communication device, the resource utilization rate of the second communication device, and the communication requirements of the second communication device.

[0017] Optionally, the priority of the frequency domain resource type corresponding to the frequency domain resource is determined according to the priority of the SSB carried by the frequency domain resource, or the priority of the frequency domain resource type corresponding to the frequency domain resource is determined according to the access priority of the frequency domain resource, or the priority of the frequency domain resource type corresponding to the frequency domain resource is determined according to the priority of the PLMN corresponding to the frequency domain resource.

[0018] In one possible implementation, the first frequency domain resource is either a set of frequency domain resources or a group of frequency domain resources; the set of frequency domain resources includes one or more groups of frequency domain resources. That is, measurement reports can be reported according to different granularities. For example, if the first frequency domain resource is a set of frequency domain resources, reporting measurement reports at the granularity of the set of frequency domain resources can reduce the number of reported measurement reports and lower resource overhead. Conversely, if the first frequency domain resource is a group of frequency domain resources, reporting measurement reports at the granularity of the group of frequency domain resources—that is, reporting measurement reports at a finer granularity—can improve the accuracy of the reported measurement reports.

[0019] In one possible implementation, the method provided by the first aspect further includes: when a first measurement reporting trigger condition is met, the first communication device reports a measurement report. Thus, by reporting a measurement report only when the first measurement reporting trigger condition is met, the reporting overhead of the measurement report can be reduced, resources can be saved, and communication performance can be improved.

[0020] Secondly, a communication method is provided. The communication method includes: a second communication device generating first information, wherein the first information is used to determine measurement reporting trigger conditions corresponding to K types of frequency domain resources, the frequency domain resource type being related to the operator corresponding to the frequency domain resource and / or whether it is an anchor frequency domain resource, and K being a positive integer; and the second communication device sending the first information.

[0021] Based on the communication method provided in the second aspect, the second communication device can send first information to indicate the measurement reporting trigger conditions corresponding to the K types of frequency domain resources, so that the first communication device can determine whether to report a measurement report according to the measurement reporting trigger conditions corresponding to the frequency domain resource types. In this way, whether to report a measurement report matches the frequency domain resource type of the first frequency domain resource, thereby improving the flexibility of measurement report reporting.

[0022] As an example, the second communication device may be a network device, a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts may be used in a network device.

[0024] In one possible implementation, the measurement reporting triggering conditions corresponding to the K types of frequency domain resources include the first measurement reporting triggering condition corresponding to the frequency domain resource type of the first frequency domain resource, the first frequency domain resource being used for communication by the first communication device, and the first measurement reporting triggering condition being used to determine whether to report a measurement report.

[0025] Optionally, the first measurement reporting trigger condition includes at least one of the following: the channel quality corresponding to the first frequency domain resource is greater than or equal to a first threshold; or, the channel quality corresponding to the first frequency domain resource is less than or equal to a second threshold; or, the channel quality corresponding to the second frequency domain resource is greater than or equal to the channel quality corresponding to the first frequency domain resource, and the difference between the channel quality corresponding to the second frequency domain resource and the channel quality corresponding to the first frequency domain resource is greater than or equal to a third threshold; or, the channel quality corresponding to the second frequency domain resource is greater than or equal to a fourth threshold; or, the channel quality corresponding to the first frequency domain resource is less than or equal to a fifth threshold, and the channel quality corresponding to the second frequency domain resource is greater than or equal to a sixth threshold. Wherein, the second frequency domain resource and the first frequency domain resource are located in the same frequency band, and the second frequency domain resource and the first frequency domain resource correspond to different network devices or cells; or, the frequency band in which the second frequency domain resource is located is different from the frequency band in which the first frequency domain resource is located.

[0026] In one possible implementation, the first information indicates K sets of parameters. The k-th set of parameters in the K sets is used to determine the measurement reporting trigger condition corresponding to the k-th frequency domain resource type among the K frequency domain resource types, where k is a positive integer less than or equal to K. Optionally, the k-th set of parameters corresponds to a frequency domain resource group or a set of frequency domain resources.

[0027] In one possible implementation, the first information indicates the parameters corresponding to the i-th frequency domain resource type among the K frequency domain resource types, as well as parameter information used to determine the measurement reporting trigger condition corresponding to at least one frequency domain resource type other than the i-th frequency domain resource type. The parameters corresponding to the i-th frequency domain resource type are used to determine the measurement reporting trigger condition corresponding to the i-th frequency domain resource type, where i is a positive integer less than or equal to K.

[0028] Optionally, the parameters corresponding to the i-th frequency domain resource type correspond to a frequency domain resource group or a frequency domain resource set; and / or, the parameter information of the measurement reporting trigger condition corresponding to at least one frequency domain resource type corresponds to a frequency domain resource group or a frequency domain resource set.

[0029] In one possible implementation, the measurement reporting trigger condition is related to the priority of the frequency domain resource type.

[0030] In one possible implementation, the priority of the frequency domain resource type is related to at least one of the following: the characteristics of the first communication device, the requirements of the first communication device, the resource utilization rate of the second communication device, and the communication requirements of the second communication device.

[0031] In one possible implementation, the first frequency domain resource is a set of frequency domain resources, or the first frequency domain resource is a group of frequency domain resources; the set of frequency domain resources includes one or more groups of frequency domain resources.

[0063] The technical solutions of this application embodiment can be applied to various communication systems, such as wireless fidelity (WiFi) systems, vehicle-to-everything (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, 5th generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems, etc.

[0064] This application will present various aspects, embodiments, or features relating to systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches are also possible.

[0065] Furthermore, in the embodiments of this application, words such as "exemplarily" and "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as an "example" in this application should not be construed as being better or more advantageous than other embodiments or designs. Rather, the use of the word "example" is intended to present the concept in a specific manner.

[0066] First, in this application, "for indicating" can include both direct and indirect indication. When describing "information" for indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.

[0067] The information indicated by a given piece of information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent. At the same time, common parts of various pieces of information can be identified and indicated uniformly to reduce the indication overhead caused by individually indicating the same information.

[0068] Furthermore, the specific indication method can also be any existing indication method, such as, but not limited to, the above-mentioned indication methods and their various combinations. Specific details of various indication methods can be found in existing technologies, and will not be repeated here. As described above, for example, when multiple pieces of information of the same type need to be indicated, the indication methods for different pieces of information may differ. In the specific implementation process, the required indication method can be selected according to specific needs. This application embodiment does not limit the selected indication method; therefore, the indication methods involved in this application embodiment should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated.

[0069] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. This configuration information can include, for example, but not limited to, higher-layer signaling and / or physical-layer signaling. For example, higher-layer signaling can include radio resource control (RRC) signaling or medium access control (MAC) layer signaling. This configuration information can include, for example, but not limited to, one or a combination of at least two of higher-layer and physical-layer signaling. MAC layer signaling includes, for example, a medium access control-control element (MAC CE); physical (PHY) layer signaling includes, for example, downlink control information (DCI).

[0070] Second, in the embodiments shown below, the first, second, and various numerical designations are merely distinctions for descriptive convenience and are not intended to limit the scope of the embodiments of this application. For example, to distinguish different indication information.

[0071] Third, "pre-defined," "pre-configured," or "pre-specified" can be achieved by pre-saving corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including terminal devices and network devices), or by pre-defining them in a protocol. This application does not limit the specific implementation method. "Saving" can refer to saving in one or more memories. These memories can be separate installations or integrated into the encoder, decoder, processor, or communication device. Alternatively, some memories can be separately installed, while others are integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this.

[0072] Fourth, the “protocol” involved in the embodiments of this application may refer to standard protocols in the field of communications, such as LTE protocols of the 3rd generation partnership project (3GPP) (such as technical specification (TS) 36, i.e., the TS36 series of technical specifications), NR protocols (such as the TS38 series of technical specifications), and related protocols applied to future communication systems. This application does not limit this.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

This terminal equipment can also be referred to as user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user apparatus.

The terminal device in this application can also be an onboard module, onboard unit, onboard component, onboard chip, or onboard unit, which is built into a vehicle as one or more components or units. The terminal device can also be other devices with terminal functions; for example, it can be a device that performs terminal functions in D2D communication. The embodiments of this application do not limit the device form of the terminal device. The device used to implement the function of the terminal device can be the terminal device itself; it can also be a device that supports the terminal device in implementing the function, such as a communication module, chip, chip system, other components or parts, or circuits or functional components. This device can be installed in the terminal device or used in conjunction with the terminal device. The chip system can be composed of chips or include chips and other discrete devices.Among them, the various forms of terminal devices mentioned above can also be referred to as terminal-side devices.

[0080] In this application embodiment, the access network device can be a device with wireless transceiver capabilities. For example, the access network device can be a device located in the access network (AN) of a communication system, which can be used to provide access services for terminal devices. In one possible scenario, the access network device can be a radio access network (RAN) device, such as a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), an integrated access and backhaul (IAB) node, an IAB parent node, or a base station in a future communication system. In future mobile communication systems, the access network device may also have other naming conventions, all of which are covered within the protection scope of this application embodiment, and this application does not impose any limitations on them. Alternatively, the access network device may also include 5G, such as a gNB in ​​an NR system, or one or a group (including multiple antenna panels) of antenna panels of a 5G base station, or it may be a network node constituting a gNB, a transmission point (TRP or transmission point (TP), or a transmission measurement function (TMF). Alternatively, the access network device can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. Optionally, the access network device can also be a server, wearable device, vehicle, or in-vehicle equipment, etc. For example, the access network device in V2X technology can be an RSU. All or part of the functions of the access network device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The access network device in this application can also be a logical node, logical module, or software capable of implementing all or part of the access network device functions.

[0081] In another possible scenario, multiple access network devices collaborate to assist terminal devices in achieving wireless access, with each access network device performing a portion of the base station's functions. For example, the access network devices can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and DU can be configured separately or included in the same network element, such as a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0082] In different systems, CU (or centralized unit control plane (CU-CP)) and centralized unit user plane (CU-UP)), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (O-RAN or ORAN) system, CU can also be called an open centralized unit (O-CU) (open CU), DU can also be called an open distributed unit (O-DU), CU-CP can also be called an open centralized unit control plane (O-CU-CP), CU-UP can also be called an open centralized unit user plane (O-CU-UP), and RU can also be called an open radio unit (O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the CU (or CU-CP, CU-UP), DU and RU units in this application can be implemented through a software module, a hardware module, or a combination of software and hardware modules.

[0083] In this embodiment, the form of the network device is not limited. The device used to implement the function of the network device can be the network device itself; it can also be any device that supports the network device in implementing that function, such as a communication module, chip, chip system, other components or parts, or circuits or functional components. This device can be installed in the network device or used in conjunction with the network device. The chip system can be composed of chips or can include chips and other discrete devices. The network devices of the various forms described above can also be referred to as network-side devices.

[0084] It should be understood that Figure 1 is a simplified schematic diagram for ease of understanding only, and the communication system may also include other network devices and / or other terminals, which are not shown in Figure 1.

[0085] 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.

[0086] In wireless communication systems (such as the system shown in Figure 1), wireless communication resources may include time-frequency resources. The following explanation of time-frequency resources will use an NR system as an example. It should be understood that NR can also be replaced with 5G or 5G NR.

[0087] The technical terms and related technical solutions in this application will be described below with reference to the accompanying drawings.

[0088] 1. Parameter set (numerology).

[0089] 5G NR introduces the concept of a parameter set, which includes sub-carrier spacing (SCS) and corresponding parameters such as symbol length and cyclic prefix (CP) length. Because there is a mapping relationship between SCS and symbol length / CP length, SCS is often used instead of parameter set in some literature.

[0090] For example, the parameters involved in the parameter set are shown in Table 1.

[0091] Table 1

[0092] In Table 1, μ represents the subcarrier spacing index, or μ represents the parameter set, CP length includes the normal CP length and the extended CP length, and FR represents the frequency range (FR).

[0093] 2. Channel.

[0094] 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 future communication systems. Of course, future communication systems may still use PDCCH to represent the physical downlink control channel or physical transmit link control channel of the terminal device.

[0095] 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 refers to the physical layer data channel received by the terminal device, similar in function to the Physical Downlink Shared Channel (PDSCH) in LTE and 5G. PRxSCH may be a newly introduced physical layer data channel in future communication systems. However, future communication systems may still use PDSCH to represent the physical downlink data channel or physical reception link data channel of the terminal device.

[0096] 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 refers to the physical layer control channel transmitted by the terminal device, similar in function to the Physical Uplink Control Channel (PUCCH) in LTE and 5G. PTxCCH may be a new physical layer control channel introduced in future communication systems. However, future communication systems may still use PUCCH to represent the physical uplink control channel or physical transmission link control channel of the terminal device.

[0097] 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 refers to the physical layer data channel transmitted by the terminal device, similar in function to the Physical Uplink Shared Channel (PUSCH) in LTE and 5G. PTxSCH may be a new physical layer data channel introduced in future communication systems. However, future communication systems may still use PUSCH to represent the physical uplink data channel or physical receive link data channel of the terminal device.

[0098] 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.

[0099] Multi-operator spectrum sharing refers to the ability of multiple operators to conduct wireless network communication on the same spectrum segment, meaning multiple operators can operate in the same frequency band and share the same spectrum. For example, operator A can communicate with terminal device 1 on spectrum resource A, and operator B can also communicate with terminal device 2 on spectrum resource A.

[0100] 3. Public Land Mobile Network (PLMN).

[0101] 3.1 A PLMN is a network established and operated by a competent authority or an authorized private telecommunications entity to provide terrestrial mobile communication services to the public.

[0102] A PLMN ID is the network identifier corresponding to a PLMN, which includes the mobile country code (MCC) and the mobile network code (MNC). An operator owns one or more PLMN IDs, and each PLMN ID is globally unique.

[0103] 3.2 Classification of PLMNs.

[0104] The location of terminal devices in a mobile network changes dynamically. To ensure that terminal devices can access mobile network services normally in different locations, the access and mobility management function (AMF) in the core network manages the access and mobility of terminal devices. During the AMF's access and mobility management process, when a terminal device registers, disconnects from the network, or re-enters the network, the same PLMN will be identified as different categories. For example, the relevant concepts of PLMN can be shown in Table 2.

[0105] Table 2

[0106] When a terminal device powers on or disconnects from the network, it will trigger a search for the PLMN. Terminal devices can search for the PLMN automatically or manually.

[0107] (1) Automatic network search refers to selecting a suitable PLMN for access based on the PLMN information recorded in the memory or SIM card, according to priority. For example, the terminal device's PLMN selection status includes one of the following three states: Trying to register with the PLMN (Trying RPLMN / PLMN), Waiting for the PLMN (Wait for PLMNs / Wait for PLMNs to appear), or Successfully registered on the PLMN (On PLMN).

[0108] When attempting to register a PLMN, the terminal device prioritizes RPLMN for registration. If the registration is successful, the terminal device will enter a state of successful registration on the PLMN. If the registration fails, the terminal device will begin selecting PLMNs according to the following priority: EPLMN, EHPLMN, HPLMN, UPLMN, OPLMN, VPLMN, and other PLMNs.

[0109] If the terminal device searches for all PLMNs but still finds no available PLMN, the terminal device enters a state of waiting for a PLMN.

[0110] Once a PLMN is successfully registered, the terminal device will periodically monitor the PLMN information. When the successfully registered PLMN becomes unavailable, the terminal device will enter a state of attempting to register a new PLMN and select a new PLMN.

[0111] Waiting for a PLMN: Currently, there are no allowed or available PLMNs, and the terminal device is waiting for a PLMN to appear. The terminal device will periodically search for available PLMNs. When an available PLMN appears, the terminal device enters the state of attempting to register a PLMN and selects a new PLMN.

[0112] During the automatic network search process, the terminal device can periodically detect the PLMN and continuously change between three states of selecting the PLMN.

[0113] (2) Manual network search refers to the terminal device providing the user with a list of available PLMNs, allowing the user to choose a PLMN to connect to. When the terminal device selects a PLMN from the list of available PLMNs, initiates registration, and the registration is successful, the terminal device can obtain normal network services.

[0114] 3.3. Multiple operators share the network.

[0115] In a communication system, there may be multiple operators, and different operators can share networks. Each operator can provide communication services to its own users, and each operator has its own core network. As shown in Figure 2, taking operators A and B as examples, operators A and B share access network equipment, and each operator A and operator B corresponds to a core network. Terminal devices (which can also be understood as users) corresponding to operator A communicate with operator A's core network through the access network equipment, and terminal devices (which can also be understood as users) corresponding to operator B communicate with operator B's core network through the access network equipment.

[0116] Different operators can share networks in the following ways: independent carrier access network (RAN) sharing and multi-operator core network (MOCN) sharing.

[0117] In a shared independent carrier access network (ICN), multiple operators each have their own complete core network, and while they share RAN equipment, they do not share radio spectrum resources. In this ICN scenario, for the core network, it's equivalent to a single set of radio equipment being divided into multiple "virtual devices," with each core network interface connecting to these "virtual" devices. For example, consider operators A and B. As shown in Figure 3(a), assuming operators A and B share a network using an ICN sharing method, the core network elements of operator A and operator B are independent of each other. For instance, operator A's core network elements include a Mobility Management Entity (MME)1 connected to the access network equipment, a System Architecture Evolution-Gateway (SAE-GW)1 connected to MME1, and a Home Subscriber Server (HSS)1 connected to MME1. Operator B's core network elements include an MME2 connected to the access network equipment, an SAE-GW2 connected to MME2, and an HSS2 connected to MME2. Operator A and Operator B share access network equipment, but the frequencies used by different operators for providing services on the access network equipment are different. For example, Operator A uses cell 1 to provide services, while Operator B uses cell 2. Cell 1 and cell 2 use different frequencies.

[0118] In MOCN (Multi-access Network) sharing, multiple operators share the radio access network and radio spectrum resources, but not the core network equipment, thus saving operators' investment costs. Throughout the solution, operators share radio spectrum resources. Access network equipment broadcasts information indicating multiple PLMNs within the same spectrum (e.g., a cell). Terminal devices can identify the multiple PLMNs broadcast by the access network equipment and select the appropriate PLMN for access. For example, consider operators A and B. As shown in Figure 3(b), assuming operators A and B share the network in MOCN mode, the core network elements of operator A and operator B are independent. For example, operator A's core network elements include MME1 connected to the access network equipment, SAE-GW1 connected to MME1, and HSS1 connected to MME1; operator B's core network elements include MME2 connected to the access network equipment, SAE-GW2 connected to MME2, and HSS2 connected to MME2. Operators A and B share access network equipment, and the frequencies used by different operators for providing services on the access network equipment are the same. For example, operator A uses cell 3 to provide services, and operator B also uses cell 3 to provide services.

[0119] It is understood that the MME1 mentioned above can also be replaced by Serving General Packet Radio Service Support Node (SGSN)1, MME2 can also be replaced by SGSN2, HSS1 can also be replaced by Home Location Register (HLR)1, and HSS2 can also be replaced by HLR2.

[0120] It is understood that the core network elements in Figure 3 above are for illustrative purposes. In different evolved versions of communication systems, the core network elements may have other possible names, and the core network may include more or fewer network elements, which will not be elaborated here.

[0121] 4. Frequency domain resource set.

[0122] A frequency domain resource set refers to a collection of one or more frequency domain resource groups. A frequency domain resource set can support communication of a cell on at least one frequency domain resource group within a frequency band. For example, a frequency domain resource set may include one or more frequency domain resource groups within the same frequency band, or it may include multiple carriers within multiple frequency bands. A frequency domain resource group may include one or more component carriers (CCs), or a component carrier representing a portion of the frequency domain resources; in this case, a frequency domain resource set may include one or more carriers. It is understood that a frequency domain resource set can also be called a uni-carrier, a carrier group (CC group), and a carrier group comprising one or more frequency domain resource groups. Alternatively, a frequency domain resource set may have other possible names, which will not be elaborated upon here.

[0123] A frequency band can refer to a segment of frequency domain resources, which may include contiguous resources or discontinuous resources. Optionally, the frequency band in this application may be the operating band defined by the NR protocol in the prior art, or it may be a portion of the frequency domain resources within the operating band.

[0124] In a communication system, one or more frequency domain resource sets can be configured. For example, as shown in Figure 4, an access network device can be configured with three frequency domain resource sets, such as frequency domain resource set 0, frequency domain resource set 1, and frequency domain resource set 2. Frequency domain resource set 0 can include multiple frequency domain resource groups, frequency domain resource set 1 can include multiple frequency domain resource groups, and frequency domain resource set 2 can include multiple frequency domain resource groups. The same frequency domain resource set is configured using the same information or signaling. For example, the same frequency domain resource set can be configured using the same system information. When multiple frequency domain resource sets are configured in a communication system, one or more frequency domain resource sets can be configured using the same information or signaling.

[0125] Optionally, a group of frequency-domain resources within the same frequency-domain resource set is equivalent to a logical carrier. For example, groups of frequency-domain resources within the same set can share a single radio frequency channel, and / or the signals carried by groups of frequency-domain resources within the same set can be subjected to FFT operations together. Referring to frequency-domain resource sets 0 to 2 in Figure 4 above, frequency-domain resource set 0 is equivalent to a logical carrier, frequency-domain resource set 1 is equivalent to a logical carrier, and frequency-domain resource set 2 is equivalent to a logical carrier. It should be understood that some frequency-domain resources within the same frequency-domain resource set can also be equivalent to a logical carrier.

[0126] Optionally, frequency domain resource sets can be divided according to the frequency band or frequency range in which the frequency domain resource group is located. Taking a CC as an example, multiple CCs within frequency range 1 (FR1) form a frequency domain resource set, multiple CCs within frequency range 2 (FR2) form a frequency domain resource set, and multiple CCs within frequency range 3 (FR3) form a frequency domain resource set. The frequency range of FR1 is 450 MHz to 6000 MHz. FR1 can also be referred to as the 6 GHz (Sub-6 GHz) band. The frequency range of FR2 is 24250 MHz to 52600 MHz. FR2 is often referred to as the millimeter wave (mmWave) band. The frequency range of FR3 is 6000 MHz to 24250 MHz. FR3 is the band between FR1 and FR2, and is often referred to as the 24 GHz (Sub-24 GHz) band. It is understood that the frequency domain resource allocation method described here is only for illustrative purposes. In actual implementation, the same frequency domain resource set may also include CCs from different frequency ranges, or the same frequency domain resource set may include some CCs from the same frequency range. It is understood that each frequency range may include at least one frequency band.

[0127] The frequency band in this application can be FR1, FR2, or FR3. FR3 refers to the frequency band located between 6000MHz and 24250MHz. FR3 is the frequency band between FR1 and FR2, and can be referred to as the "Sub-24 GHz" frequency band.

[0128] The frequency ranges FR1, FR2, and FR3 in this embodiment are for illustrative purposes only. In actual implementation, other ways of dividing the frequency range may exist, which will not be elaborated here.

[0129] For two frequency domain resources in the same frequency domain resource set, they can be co-located (i.e. used for communication between the same access network device and terminal device) or non-co-located (i.e. used for communication between different access network devices and terminal devices).

[0130] 5. Carrier aggregation (CA).

[0131] Carrier aggregation provides greater bandwidth to a single terminal device by aggregating multiple carrier aggregation (CCs). This allows the terminal device to enjoy bandwidth equal to the total bandwidth of all CCs, thereby increasing peak rates.

[0132] CA can be applied to 3CC aggregation scenarios. In this case, a terminal device is served by three carriers simultaneously, one of which is the primary component carrier (PCC), and the other two are secondary component carriers (SCCs). The cell where the PCC is located is called the primary cell (PCell), and the cell where the SCC is located is called the secondary cell (SCell).

[0133] Based on whether the aggregated multiple CCs belong to the same frequency band and are continuous in the frequency domain, CA can be divided into the following categories: (1) Intra-band contiguous CA, where multiple CCs belong to the same frequency band and are continuous in the frequency domain. (2) Intra-band non-contiguous CA, where multiple CCs belong to the same frequency band but are not continuous in the frequency domain. (3) Inter-band CA, where multiple CCs belong to different frequency bands. In this case, the multiple CCs are usually not continuous in the frequency domain.

[0134] In wireless communication systems, terminal devices can measure channel state information and trigger the reporting of measurement reports based on the measured channel state information. In some schemes, when a terminal device sends a measurement report, the network device configures the reporting conditions for the terminal device. However, the above-mentioned measurement report reporting schemes have only one reporting condition and are not flexible enough.

[0135] To address the aforementioned technical problems, this application provides a communication method. The method includes: a first communication device receiving first information, wherein the first information is used to determine measurement reporting trigger conditions corresponding to K types of frequency domain resources, the frequency domain resource type being related to the operator corresponding to the frequency domain resource and / or whether it is an anchor frequency domain resource, and K being a positive integer; determining whether to report a measurement report based on the first measurement reporting trigger condition corresponding to the frequency domain resource type of the first frequency domain resource. This ensures that whether to report a measurement report matches the frequency domain resource type of the first frequency domain resource, thereby improving the flexibility of measurement report reporting.

[0136] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0137] It should be noted that the communication method provided in this application embodiment can be applied between any two devices shown in Figure 1, such as between a terminal device and an access network device. For specific implementation, please refer to the following method embodiment, which will not be repeated here.

[0138] It should be noted that the solutions in the embodiments of this application can also be applied to other communication systems, and the corresponding names can be replaced by the names of the corresponding functions in other communication systems.

[0139] The communication method provided in the embodiments of this application will be described in detail below with reference to Figure 5.

[0140] For example, Figure 5 is a schematic flowchart of a communication method provided in an embodiment of this application. This communication method can be applied to communication between a first communication device (the terminal device shown in Figure 1) and a second communication device (the access network device shown in Figure 1). For ease of understanding, the following embodiments will use the first communication device as the first terminal device and the second communication device as the access network device as examples.

[0141] As shown in Figure 5, the communication method includes:

[0142] S501, the second communication device generates the first information.

[0143] The first piece of information is used to determine the measurement reporting trigger conditions corresponding to the K types of frequency domain resources. The frequency domain resource type is related to the operator corresponding to the frequency domain resource and / or whether it is an anchor frequency domain resource. K is a positive integer.

[0144] In one possible implementation, operator-shared frequency domain resources refer to frequency domain resources corresponding to at least two operators, i.e., frequency domain resources that can be shared by at least two operators. For example, if a frequency domain resource corresponds to operator A and operator B, then that frequency domain resource is an operator-shared frequency domain resource. Similarly, if a frequency domain resource corresponds to operator A, operator B, and operator C, then that frequency domain resource is an operator-shared frequency domain resource. It can be understood that if a frequency domain resource is an operator-shared frequency domain resource, then at least two operators corresponding to that frequency domain resource can provide communication services to terminal devices on that frequency domain resource, and that frequency domain resource can also be referred to as an operator-shared frequency domain resource corresponding to that frequency domain resource.

[0145] In one possible implementation, the anchor frequency domain resource is a frequency domain resource that carries information for access control, such as a frequency domain resource carrying at least one of the following: information for camping, paging messages, low-power wake-up signals, or uplink wake-up signals. The anchor frequency domain resource can also be understood as a frequency domain resource used for access control, or as a frequency domain resource used to meet the coverage performance requirements of the terminal device.

[0146] Optionally, the anchor frequency domain resource may include frequency domain resources used to carry uplink signals (i.e., uplink frequency domain resources) and / or frequency domain resources used to carry downlink signals (i.e., downlink frequency domain resources). Here, an anchor frequency domain resource that is an uplink frequency domain resource can also be called an uplink anchor frequency domain resource, and an anchor frequency domain resource that is a downlink frequency domain resource can also be called a downlink anchor frequency domain resource. As an example, when the anchor frequency domain resource is a frequency division multiplexing (FDM) frequency domain resource, i.e., when uplink and downlink use a frequency division method, the anchor frequency domain resource may include uplink anchor frequency domain resources and / or downlink anchor frequency domain resources. It is understood that in time division multiplexing (TDM), i.e., when uplink and downlink use a time division method, the anchor frequency domain resource may also include uplink anchor frequency domain resources. The functionality of both uplink and downlink anchor frequency domain resources can be implemented through resources at different frequency positions on the anchor frequency domain resource.

[0147] The implementation principle of "the frequency domain resource type being related to the corresponding operator and / or whether it is an anchor frequency domain resource" will be explained later and will not be elaborated here.

[0148] Measurement reporting trigger conditions are used to determine whether to report a measurement report. The terminal device can determine whether to report a measurement report based on the channel quality corresponding to the frequency domain resources and the corresponding measurement reporting trigger conditions.

[0149] Each of the K frequency domain resource types corresponds to a measurement reporting trigger condition. The measurement reporting trigger condition for each of the K frequency domain resource types can be determined based on at least one of the following events: event 1, event 2, event 3, event 4, or event 5. For ease of description, the event used to determine the measurement reporting trigger condition corresponding to the k-th frequency domain resource type will be referred to as the event associated with the k-th frequency domain resource type, and will not be elaborated further.

[0150] Event 1 includes: the channel quality corresponding to frequency domain resource #1 is greater than or equal to x1.

[0151] Event 2 includes: the channel quality corresponding to frequency domain resource #1 is less than or equal to x2.

[0152] Event 3 includes: the channel quality corresponding to frequency domain resource #1 is greater than or equal to the channel quality corresponding to frequency domain resource #2, and the difference between the channel quality corresponding to frequency domain resource #2 and the channel quality corresponding to frequency domain resource #1 is greater than or equal to x3.

[0153] Event 4 includes: the channel quality corresponding to frequency domain resource #2 is greater than or equal to x4.

[0154] Event 5 includes: the channel quality corresponding to frequency domain resource #1 is less than or equal to x5, and the channel quality corresponding to frequency domain resource #2 is greater than or equal to x6.

[0155] The channel quality includes at least one of the following: reference signal receiving power (RSRP); or reference signal receiving quality (RSRQ); or reference signal-signal to interference plus noise ratio (RS-SINR); or channel quantity indicator (CQI).

[0156] The channel quality corresponding to a frequency domain resource is related to the measurement results of the channel quality on that frequency domain resource. For example, the channel quality corresponding to a frequency domain resource is a function of the measurement results of the channel quality on that frequency domain resource. Specifically, the channel quality corresponding to frequency domain resource #1 is related to the measurement results of the channel quality on frequency domain resource #1, and the channel quality corresponding to frequency domain resource #2 is related to the measurement results of the channel quality on frequency domain resource #2.

[0157] For example, a function of the channel quality measurement result on the frequency domain resource can be a mathematical operation of the channel quality measurement result on the frequency domain resource with a hysteresis parameter and / or a specific offset, including but not limited to at least one of the following: channel quality measurement result on the frequency domain resource + hysteresis parameter, channel quality measurement result on the frequency domain resource - hysteresis parameter, channel quality measurement result on the frequency domain resource + specific offset - hysteresis parameter, channel quality measurement result on the frequency domain resource + specific offset + hysteresis parameter, channel quality measurement result on the frequency domain resource + specific offset, or, channel quality measurement result on the frequency domain resource - specific offset.

[0158] Event 1 can indicate that, for a communication device (such as a terminal device), frequency domain resource #1 has superior performance, and the communication device can be located at or near the center of frequency domain resource #1. Event 2 can indicate that, for a communication device (such as a terminal device), frequency domain resource #2 has inferior performance. Event 3 can indicate that, for a communication device (such as a terminal device), frequency domain resource #2 has better performance than the carrier performance of frequency domain resource #1. Event 4 can indicate that, for a communication device (such as a terminal device), frequency domain resource #2 has superior performance. Event 5 can indicate that, for a communication device (such as a terminal device), frequency domain resource #2 has better performance than frequency domain resource #1. Frequency domain resource #1 is a frequency domain resource that provides communication services; for example, frequency domain resource #1 is a frequency domain resource on a serving cell, which can be a cell communicating with the first communication device.

[0159] Optionally, the aforementioned serving cell can be a cell specified by the network device. In some examples, frequency domain resource #2 and frequency domain resource #1 are located in the same frequency band, and frequency domain resource #2 and frequency domain resource #1 correspond to different network devices (such as neighboring base stations) or cells. For example, frequency domain resource #1 is the frequency domain resource for communication between the second communication device and the first communication device, and frequency domain resource #2 is the frequency domain resource on the third communication device. Alternatively, in other examples, frequency domain resource #2 and frequency domain resource #1 are located in different frequency bands, and frequency domain resource #2 and frequency domain resource #1 can come from the same network device or cell, or they can come from different network devices or cells. Frequency domain resource #2 can also be understood as a neighboring cell of frequency domain resource #1. It should be understood that the first communication device can receive signals on frequency domain resource #2. x1, x2, x3, x4, and x5 are all threshold parameters. Optionally, the values ​​of the threshold parameters can be real numbers.

[0160] In some examples, the measurement reporting trigger condition can be positively or negatively correlated with the priority of the frequency domain resource type. This can also be understood as the threshold parameter values ​​for different events being positively or negatively correlated with the priority of the frequency domain resource type. The second communication device can determine the threshold parameter values ​​for each time period based on the priority of different events and frequency domain resource types, thereby determining the measurement reporting trigger condition. In this way, the measurement reporting trigger condition can be determined based on the priority of the frequency domain resource type, achieving priority-based measurement reporting and meeting the measurement reporting requirements of different scenarios and / or events. The following examples, using events 1 to 5, illustrate the relationship between the measurement reporting trigger condition and the priority of the frequency domain resource type.

[0161] For event 1, the priority of the frequency domain resource type is negatively correlated with the value of x1. For example, the lower the priority of the frequency domain resource type, the larger the value of x1; the higher the priority of the frequency domain resource type, the smaller the value of x1.

[0162] For event 2, the priority of the frequency domain resource type is positively correlated with the value of x2. For example, the lower the priority of the frequency domain resource type, the smaller the value of x2; the higher the priority of the frequency domain resource type, the larger the value of x2.

[0163] For event 3, the priority of the frequency domain resource type is negatively correlated with the value of x3. For example, the lower the priority of the frequency domain resource type, the larger the value of x3; the higher the priority of the frequency domain resource type, the smaller the value of x3.

[0164] For event 4, the priority of the frequency domain resource type is negatively correlated with the value of x4. For example, the lower the priority of the frequency domain resource type, the larger the value of x4; the higher the priority of the frequency domain resource type, the smaller the value of x4.

[0165] For event 5, the priority of the frequency domain resource type is positively correlated with the value of x5, and negatively correlated with the value of x6. For example, the lower the priority of the frequency domain resource type, the smaller the value of x5 and the larger the value of x6; the higher the priority of the frequency domain resource type, the larger the value of x5 and the smaller the value of x6.

[0166] Optionally, the priority of frequency domain resource types is related to the communication scenario, wherein the communication scenario is related to at least one of the following: the characteristics of the first communication device, the requirements of the first communication device, the resource utilization rate of the second communication device, and the communication requirements of the second communication device. Alternatively, the priority of frequency domain resource types can be understood as being related to at least one of the following: the characteristics of the first communication device, the requirements of the first communication device, the resource utilization rate of the second communication device, and the communication requirements of the second communication device.

[0167] Optionally, the priority of the frequency domain resource type is related to the characteristics corresponding to the first communication device. The characteristics corresponding to the first communication device can also be the characteristics of the user using the first communication device. For example, for a first communication device corresponding to a high-priority user, such as a paid premium member (VIP), the priority of the operator-dedicated frequency domain resource corresponding to the first communication device is higher than the priority of the operator-shared frequency domain resource corresponding to the first communication device. For low-priority users, such as ordinary users, the priority of the operator-shared frequency domain resource corresponding to the first communication device is higher than the priority of the operator-dedicated frequency domain resource corresponding to the first communication device.

[0168] For example, for high-priority users, such as VIP users, the capacity frequency domain resources corresponding to the first communication device have a higher priority than the anchor frequency domain resources corresponding to the first communication device. For low-priority users, such as ordinary users, the anchor frequency domain resources corresponding to the first communication device have a higher priority than the capacity frequency domain resources corresponding to the terminal device.

[0169] For example, for high-priority users, such as VIP users' terminal devices, the more frequency domain resources associated with the corresponding operator (including the operator associated with the terminal device), the lower the priority. For low-priority users, such as ordinary users, the fewer frequency domain resources associated with the corresponding operator (including the operator associated with the terminal device), the lower the priority.

[0170] Optionally, the priority of frequency domain resource types is related to the needs of the terminal device. The needs of the terminal device can also be the needs of the users using the terminal device, such as the amount of data the terminal device needs to transmit.

[0171] For example, in scenarios where the number of terminal devices is less than or equal to the seventh threshold and / or the service demand is less than or equal to the eighth threshold, the priority of operator-shared frequency domain resources is higher than the priority of operator-dedicated frequency domain resources. In scenarios where the number of terminal devices exceeds the seventh threshold and the service demand exceeds the eighth threshold, the priority of operator-dedicated frequency domain resources is higher than the priority of operator-shared frequency domain resources.

[0172] For example, when the number of terminal users is less than or equal to the seventh threshold, the priority of anchor frequency domain resources is higher than that of capacity frequency domain resources. When the number of terminal users is greater than the seventh threshold, the priority of capacity frequency domain resources is higher than that of anchor frequency domain resources. Furthermore, for different numbers of terminal devices, if the number of terminal devices is less than the ninth threshold, the priority of frequency domain resources is as follows: priority of anchor frequency domain resources on operator-shared frequency domain resources > priority of anchor frequency domain resources on operator-dedicated frequency domain resources > priority of capacity frequency domain resources on operator-shared frequency domain resources > priority of capacity frequency domain resources on operator-dedicated frequency domain resources.

[0173] For example, regarding the amount of data a terminal device needs to transmit, among the frequency domain resources of the corresponding operators (including the operator corresponding to the terminal device), the frequency domain resources with more corresponding operators have lower priority, and those with fewer corresponding operators have higher priority. If the terminal device corresponds to operator A, and the frequency domain resources include those corresponding to operator A, those corresponding to operators A and B, and those corresponding to operators A, B, and C, then the priority of the frequency domain resources corresponding to operator A is > the priority of the frequency domain resources corresponding to operators A and B > the priority of the frequency domain resources corresponding to operators A, B, and C. It can be understood that if the operator corresponding to a frequency domain resource does not include the operator corresponding to the terminal device, then that frequency domain resource has the lowest priority relative to that terminal device.

[0174] Optionally, the priority of frequency domain resource types is related to the resource utilization rate of the second communication device. The higher the resource utilization rate, the lower the priority of the frequency domain resource. For example, if the resource utilization rate of operator-shared frequency domain resources is higher than that of operator-dedicated spectrum, then the priority of operator-dedicated frequency domain resources is higher than that of operator-shared frequency domain resources.

[0175] For example, considering the frequency domain resources corresponding to operator A, the frequency domain resources corresponding to operators A and B, and the frequency domain resources corresponding to operators A, B, and C, if the resource utilization rate of the frequency domain resources corresponding to operators A and B > the resource utilization rate of the frequency domain resources corresponding to operator A > the resource utilization rate of the frequency domain resources corresponding to operators A, B, and C, then the priority of the frequency domain resources corresponding to operators A and B < the priority of the frequency domain resources corresponding to operator A < the priority of the frequency domain resources corresponding to operators A, B, and C.

[0176] Optionally, the priority of frequency domain resource types is related to the communication needs of the second communication device. For example, if the amount of data the second communication device needs to transmit is greater than the ninth threshold, then the priority of capacity frequency domain resources is higher than that of anchor frequency domain resources, and the priority of operator-dedicated frequency domain resources is higher than that of operator-shared frequency domain resources. If the amount of data the second communication device needs to transmit is less than the ninth threshold, then the priority of capacity frequency domain resources is lower than that of anchor frequency domain resources, and the priority of operator-dedicated frequency domain resources is lower than that of operator-shared frequency domain resources. The communication needs of the second communication device can be understood as the amount of data the second communication device needs to transmit, such as the amount of data that needs to be transmitted between the second communication device and the first communication device.

[0177] For example, the higher the communication requirements of the second communication device, the lower the priority of frequency domain resources corresponding to the operator (including the operator corresponding to the terminal device), and the higher the priority of frequency domain resources corresponding to fewer operators. If the operator corresponding to the terminal device is operator A, and the frequency domain resources include those corresponding to operator A, those corresponding to operators A and B, and those corresponding to operators A, B, and C, then the priority of the frequency domain resources corresponding to operator A is > the priority of the frequency domain resources corresponding to operators A and B > the priority of the frequency domain resources corresponding to operators A, B, and C. It can be understood that if the operator corresponding to a frequency domain resource does not include the operator corresponding to the terminal device, then that frequency domain resource has the lowest priority relative to that terminal device.

[0178] It should be understood that the priority of the frequency domain resource types mentioned above is for illustrative purposes. In actual implementation, the priority of frequency domain resource types may also be related to at least two of the following: the characteristics of the first communication device, the requirements of the first communication device, the resource utilization rate of the second communication device, and the communication requirements of the second communication device. These will not be elaborated upon further.

[0179] It is understood that the priority of frequency domain resource types can be represented by numerical values, such as values ​​starting from 0, with higher values ​​indicating higher priority. This application does not limit this.

[0180] Optionally, the priority of the frequency domain resource type corresponding to the frequency domain resource can be determined based on the priority of the SSB carried by the frequency domain resource (a higher SSB priority corresponds to a higher frequency domain resource type priority), or based on the access priority of the frequency domain resource, or based on the priority of the PLMN corresponding to the frequency domain resource (indicated by the base station or predefined by the protocol). The SSB priority can be indicated by the second communication device (e.g., MIB, SIB, RRC signaling, or SSB configuration information), or predefined by a protocol (e.g., pre-configured in the first and second communication devices). The priority of the frequency domain resource type corresponding to the frequency domain resource where the SSB resides is positively correlated with the SSB priority. Similarly, the access priority of the frequency domain resource can be indicated by the second communication device, or pre-defined by a protocol (e.g., pre-configured in the first and second communication devices). The priority of the frequency domain resource type corresponding to the frequency domain resource where the access resource resides is positively correlated with the access resource priority. The PLMN priority can be indicated by the second communication device, or pre-defined by a protocol (e.g., pre-configured in the first and second communication devices). The priority of the frequency domain resource type corresponding to the PLMN is positively correlated with the priority of the PLMN.

[0181] Optionally, the priority of frequency domain resource types can be described as: the priority of the SSB carried by the frequency domain resource, the access priority of the frequency domain resource, or the priority of the PLMN corresponding to the frequency domain resource.

[0182] S502, the second communication device sends the first information.

[0183] Accordingly, the first communication device receives the first information.

[0184] The first information can be carried in higher-layer signaling (such as RRC signaling, MAC layer signaling), system information (such as system information blocks), or broadcast information. It is understood that the location of the first information here is for illustrative purposes only, and this application does not limit its scope.

[0185] S503, the first communication device determines whether to report a measurement report based on the first measurement reporting trigger condition corresponding to the frequency domain resource type of the first frequency domain resource.

[0186] In one possible implementation, the first frequency domain resource is either a set of frequency domain resources or a group of frequency domain resources; the set of frequency domain resources includes one or more groups of frequency domain resources. That is, measurement reports can be reported according to different granularities. For example, if the first frequency domain resource is a set of frequency domain resources, reporting measurement reports at the granularity of the set of frequency domain resources can reduce the number of reported measurement reports and lower resource overhead. Conversely, if the first frequency domain resource is a group of frequency domain resources, reporting measurement reports at the granularity of the group of frequency domain resources—that is, reporting measurement reports at a finer granularity—can improve the accuracy of the reported measurement reports.

[0187] It is understandable that the frequency domain resource type of the first frequency domain resource is one of the K frequency domain resource types.

[0188] In one possible implementation, the first measurement reporting trigger condition corresponding to the frequency domain resource type of the first frequency domain resource can be determined based on the first information and the event corresponding to each frequency domain resource type.

[0189] Optionally, the threshold parameter corresponding to the frequency domain resource type indicated by the first information is set to: x1 = first threshold, x2 = second threshold, x3 = third threshold, x4 = fourth threshold, x5 = fifth threshold. In this case, the first measurement reporting trigger condition includes at least one of the following:

[0190] The channel quality corresponding to the first frequency domain resource is greater than or equal to the first threshold (hereinafter referred to as condition 1); or,

[0191] The channel quality corresponding to the first frequency domain resource is less than or equal to the second threshold (hereinafter referred to as condition 2); or,

[0192] The channel quality corresponding to the second frequency domain resource is greater than or equal to the channel quality corresponding to the first frequency domain resource, and the difference between the channel quality corresponding to the second frequency domain resource and the channel quality corresponding to the first frequency domain resource is greater than or equal to the third threshold (hereinafter referred to as condition 3); or,

[0193] The channel quality corresponding to the second frequency domain resource is greater than or equal to the fourth threshold (hereinafter referred to as condition 4); or,

[0194] The channel quality corresponding to the first frequency domain resource is less than or equal to the fifth threshold, and the channel quality corresponding to the second frequency domain resource is greater than or equal to the sixth threshold (hereinafter referred to as condition 5);

[0195] Among them, the second frequency domain resource is located in the same frequency band as the first frequency domain resource, and the second frequency domain resource corresponds to different network devices or cells as the first frequency domain resource; or, the frequency band where the second frequency domain resource is located is different from the frequency band where the first frequency domain resource is located.

[0196] Thus, by using the first information to indicate K sets of parameters, different parameters can be configured for different frequency domain resource types, achieving flexibility in measurement reporting and reducing the processing complexity of the first communication device.

[0197] Optionally, the measurement reporting trigger conditions corresponding to the K types of frequency domain resources include the first measurement reporting trigger condition corresponding to the frequency domain resource type of the first frequency domain resource, the first frequency domain resource being used for communication by the first communication device, and the first measurement reporting trigger condition being used to determine whether to report a measurement report.

[0198] In one possible implementation, the measurement report is used for at least one of the following: cell handover, radio link management, radio resource management, radio link recovery, or radio link failure determination. This allows for the implementation of various resource management functions.

[0199] In one possible implementation, the first communication device determines whether to report a measurement report based on the first measurement reporting trigger condition corresponding to the frequency domain resource type of the first frequency domain resource, including: when the first measurement reporting trigger condition is met, the first communication device reports a measurement report.

[0200] In this way, the measurement report is only reported when the first measurement reporting trigger condition is met, which can reduce the reporting overhead of the measurement report, save resources, and improve communication performance.

[0201] The following example, using the first measurement reporting trigger condition, illustrates the principle of the first communication device reporting a measurement report.

[0202] The first communication device reports a measurement report when any one of the conditions included in the first measurement reporting trigger condition is met.

[0203] For example, if the first measurement reporting trigger condition includes condition 1, then the first communication device reports a measurement report if condition 1 is met.

[0204] For example, if the first measurement reporting trigger condition includes any one of conditions 1 to 5, then the first communication device reports a measurement report if any one of conditions 1 to 5 is met.

[0205] Based on the communication method provided in Figure 5, the second communication device can send first information to the first communication device, so that the first communication device can obtain the measurement reporting trigger conditions corresponding to K types of frequency domain resources, and determine whether to report a measurement report based on the resource type of the first frequency domain resource. In this way, whether to report a measurement report matches the frequency domain resource type of the first frequency domain resource, thereby improving the flexibility of measurement report reporting.

[0206] Optionally, if the first communication device determines to report a measurement report, the method provided in FIG5 further includes S504.

[0207] S504, the first communication device sends a measurement report. Correspondingly, the second communication device receives the measurement report.

[0208] Optionally, the first communication device can send measurement reports at the granularity of frequency domain resource groups. For example, for a frequency domain resource group, the channel quality on that frequency domain resource group is measured, and a measurement report is sent when the channel quality on that frequency domain resource group meets the measurement reporting trigger condition corresponding to that frequency domain resource group. In this case, one frequency domain resource group can correspond to one measurement report for one event. It can be understood that the channel quality on a frequency domain resource group can be measured by the reference signal received by the first communication device on that frequency domain resource group.

[0209] Optionally, the first communication device can send measurement reports at the granularity of frequency domain resource sets. For example, for a frequency domain resource set, the channel quality corresponding to that frequency domain resource set is measured, and a measurement report is sent when the channel quality corresponding to that frequency domain resource set meets the measurement reporting trigger condition corresponding to that frequency domain resource set. In this case, for one event, one frequency domain resource set can correspond to one measurement report. The channel quality corresponding to the frequency domain resource set can be determined based on the channel quality of at least some frequency domain resource groups in the frequency domain resource set. For example, the channel command corresponding to a frequency domain resource set can be the average measurement result of one or more frequency domain resource groups in the frequency domain resource set, or the channel command corresponding to a frequency domain resource set can be the maximum or minimum value of the channel quality of the frequency domain resource groups in the frequency domain resource set, etc., which will not be elaborated further.

[0210] In some examples, for a single event, measurement reporting is performed based on measurement results from at least a portion of the frequency domain resources in the frequency domain resource set. For instance, the first communication device reports a measurement report when the channel quality of N2 frequency domain resource groups in the frequency domain resource set meets the measurement reporting trigger condition. The N2 frequency domain resource groups can be all frequency domain resource groups in the frequency domain resource set, or a portion of them, such as the frequency domain resource group with the worst channel quality or the frequency domain resource group with the best channel quality, etc., which will not be elaborated further in the embodiments of this application.

[0211] In some examples, for a given event, measurement reporting is performed based on the average measurement results of one or more frequency domain resource groups on a frequency domain resource set.

[0212] In one possible implementation, the first and second communication devices can determine the relevant operations for cell handover, radio link management, radio link monitoring, and / or radio link recovery based on the channel quality of at least one frequency domain resource group (e.g., some or all frequency domain resource groups) in a cell, which will not be elaborated further.

[0213] The following example, using the first communication device as the terminal device, illustrates how the second communication device performs cell handover based on channel quality. Assuming the first communication device corresponds to a paid VIP user, after receiving the measurement report from the first communication device, the second communication device can prioritize switching the first communication device to the dedicated frequency domain resources of the operator corresponding to the first communication device, thereby improving the user's communication performance. Conversely, assuming the first communication device corresponds to a regular user, after receiving the measurement report from the first communication device, the second communication device can prioritize switching the first communication device to operator-shared frequency domain resources, thereby improving spectrum efficiency, reducing the power consumption of the second communication device, and achieving network energy saving.

[0214] If the number of terminal devices in the environment where the second communication device is located is less than or equal to the seventh threshold, and / or the service demand is less than or equal to the eighth threshold, then the first communication device can be preferentially switched to operator-shared frequency domain resources. If the number of terminal devices in the environment where the second communication device is located is greater than the seventh threshold and the service demand is greater than the eighth threshold, then the first communication device can be preferentially switched to operator-dedicated frequency domain resources.

[0215] As mentioned earlier, the type of frequency domain resource is related to the operator corresponding to the frequency domain resource and / or whether it is an anchor frequency domain resource. The following example illustrates this.

[0216] In contrast to frequency domain resources corresponding to at least two operators, frequency domain resources corresponding to one operator are operator-dedicated frequency domain resources, meaning they are dedicated to a single operator. If a frequency domain resource is operator-dedicated, then only the operator corresponding to that resource can provide communication services to the terminal device on that resource. In this case, the frequency domain resource can also be called the operator-dedicated frequency domain resource corresponding to that resource. It can be understood that operator-dedicated frequency domain resources and operator-shared frequency domain resources are relative to whether the number of operators corresponding to the resource is one or at least two. Compared to frequency domain resources used to carry access control information, frequency domain resources used to carry service data are called capacity frequency domain resources.

[0217] Optionally, the capacity frequency domain resource may include frequency domain resources used to carry uplink signals (i.e., uplink frequency domain resources) and / or frequency domain resources used to carry downlink signals (i.e., downlink frequency domain resources). The capacity frequency domain resource of the uplink frequency domain resource can also be referred to as the uplink capacity frequency domain resource, and the capacity frequency domain resource of the downlink frequency domain resource can also be referred to as the downlink capacity frequency domain resource. As an example, when the capacity frequency domain resource is an FDM frequency domain resource, the capacity frequency domain resource may include frequency domain resources used for uplink transmission and / or frequency domain resources used for downlink transmission. It is understood that in TDM, the frequency domain resources used for uplink transmission and the frequency domain resources used for downlink transmission on the capacity frequency domain resource may be resources at different time domain locations on the same frequency domain resource.

[0218] In some scenarios, anchor frequency domain resources can also be called coverage frequency domain resources. In other scenarios, anchor frequency domain resources can also be called anchor carriers (anchor CC) or coverage carriers (coverage CC), and capacity frequency domain resources can also be called capacity carriers (capacity CC).

[0219] In one possible implementation, the frequency domain resource type includes at least one of the following: operator-shared frequency domain resources, operator-dedicated frequency domain resources, anchor frequency domain resources, capacity frequency domain resources, operator-shared frequency domain resources that are also anchor frequency domain resources, operator-shared frequency domain resources that are also capacity frequency domain resources, operator-dedicated frequency domain resources that are also anchor frequency domain resources, and operator-dedicated frequency domain resources that are also capacity frequency domain resources.

[0220] In this embodiment, frequency domain resource types can be obtained according to different partitioning rules. The following examples illustrate frequency domain resource types using different partitioning rules.

[0221] In one possible implementation, frequency domain resource types can be divided according to rule 1.

[0222] Optionally, Rule 1 satisfies the following: the frequency domain resource type is related to whether it is a shared frequency domain resource of the operator; in other words, the frequency domain resource type is related to whether it is a dedicated frequency domain resource of the operator. In this embodiment, the frequency domain resource type is related to whether it is a shared frequency domain resource of the operator, or the frequency domain resource type is related to whether it is a dedicated frequency domain resource of the operator; this can also be understood as the frequency domain resource type being related to the operator corresponding to the operator. For a frequency domain resource, it is either a shared frequency domain resource of the operator or a dedicated frequency domain resource of the operator. In other words, if a frequency domain resource is not a shared frequency domain resource of the operator, then it is a dedicated frequency domain resource of the operator.

[0223] Optionally, frequency domain resource types can be categorized based on whether they are operator-shared or operator-dedicated. Alternatively, they can be categorized based on whether the frequency domain resource corresponds to one or at least two operators. In this case, frequency domain resource types include operator-shared frequency domain resources and operator-dedicated frequency domain resources. Taking operators A, B, and C as an example, the correspondence between frequency domain resource types and operators is shown in Table 3 below.

[0224] Table 3

[0225] Rule 1 can also be understood as meaning that frequency domain resource types can be divided according to the PLMN corresponding to the frequency domain resource. The PLMN corresponding to the frequency domain resource can refer to an actual PLMN or a virtual PLMN, such as at least one PLMN listed in Table 2. An actual PLMN is one that can be used to identify an operator, i.e., it corresponds to a single PLMN. A virtual PLMN can be used to identify a set of operators including at least one operator, i.e., it corresponds to an operator in the operator set. A PLMN corresponds to one or more operators. Taking operators A and B as examples, assume the relationship between PLMNs and operators is as shown in Table 4 below.

[0226] Table 4

[0227] Therefore, based on Table 4 above, the correspondence between frequency domain resource types and PLMNs is shown in Table 5.

[0228] Table 5

[0229] In one possible implementation, frequency domain resource types can be divided according to rule 2.

[0230] Optionally, Rule 2 satisfies the following: frequency domain resource types are classified according to whether the corresponding operators are the same, or it can also be understood as classifying frequency domain resource types based on the corresponding operators. In this case, frequency domain resources belonging to the same operator have the same frequency domain resource type, and frequency domain resources belonging to different operators have different frequency domain resource types. In some examples, for operator-shared frequency domain resources, at least one of the corresponding operators is different, and the frequency domain resource types of shared frequency domain resources belong to different operators. In some examples, operator-specific frequency domain resources belonging to the same operator have the same frequency domain resource type, and operator-specific frequency domain resources belonging to different operators have different frequency domain resource types. Taking operators A, B, and C as an example, the frequency domain resource types can include frequency domain resource type 0 to frequency domain resource type 6, where the correspondence between each frequency domain resource type and the corresponding operator is shown in Table 6 below.

[0231] Table 6

[0232] Based on Table 6 above, frequency domain resource types 0 to 2 are frequency domain resources dedicated to operators, while frequency domain resource types 3 to 6 are frequency domain resources shared by operators. Specifically, frequency domain resource type 0 is dedicated to operator A, frequency domain resource type 1 is dedicated to operator B, frequency domain resource type 3 is dedicated to operator C, frequency domain resource type 4 is shared by operators A and B, frequency domain resource type 5 is shared by operators A and C, frequency domain resource type 6 is shared by operators A, B, and C.

[0233] It is understood that the frequency domain resource types listed in Table 6 above are for illustrative purposes only. In actual implementation, operators may use fewer or more. For example, there may be two operators, such as operator A and operator B. In this case, the frequency domain resource types may include frequency domain resource type 2, frequency domain resource type 3, and frequency domain resource type 5 as shown in Table 6 above. When there are three or more operators, the implementation of the frequency domain resource types is similar to that when there are three operators, and will not be elaborated further.

[0234] In one possible implementation, frequency domain resource types can be divided according to rule 3.

[0235] Optionally, rule 3 satisfies that the frequency domain resource type is related to whether it is an anchor frequency domain resource, which can also be understood as the frequency domain resource type being related to whether it is a capacity frequency domain resource.

[0236] Optionally, frequency domain resource types are classified according to whether they are anchor frequency domain resources, or in other words, frequency domain resource types are classified according to whether they are capacity frequency domain resources. In this case, frequency domain resource types include anchor frequency domain resources and capacity frequency domain resources. That is, frequency domain resource types can include two types, such as frequency domain resource types 7 to 8. The relationship between each frequency domain resource type and whether it is an anchor frequency domain resource is shown in Table 7 below.

[0237] Table 7

[0238] Optionally, frequency domain resource types are categorized based on whether they are anchor frequency domain resources and whether they are uplink frequency domain resources. Whether a resource is an anchor frequency domain resource can also be described as whether it is a capacity frequency domain resource, and whether it is an uplink frequency domain resource can also be described as whether it is a downlink frequency domain resource. In this case, frequency domain resource types can include four types, such as frequency domain resource type 9 to frequency domain resource type 12. The relationship between each frequency domain resource type and whether it is an anchor frequency domain resource and whether it is an uplink frequency domain resource is shown in Table 8 below.

[0239] Table 8

[0240] Based on Table 8 above, frequency domain resource type 9 is uplink anchor frequency domain resource, frequency domain resource type 10 is downlink anchor frequency domain resource, frequency domain resource type 11 is uplink capacity frequency domain resource, and frequency domain resource 1 is downlink capacity frequency domain resource.

[0241] In one possible implementation, the frequency domain resource type is related to whether it is a shared frequency domain resource for operators and whether it is an anchor frequency domain resource.

[0242] In one possible implementation, frequency domain resource types can be divided according to rule 4.

[0243] Optionally, Rule 4 refers to the relationship between frequency domain resource type and whether it is a shared frequency domain resource of the operator and whether it is an anchor frequency domain resource. In this case, the frequency domain resource type can include four types, such as frequency domain resource type 13 to frequency domain resource type 16. The relationship between each frequency domain resource type and whether it is a shared frequency domain resource of the operator and whether it is an anchor frequency domain resource is shown in Table 9 below.

[0244] Table 9

[0245] In one possible implementation, frequency domain resource types can be divided according to rule 5.

[0246] Optionally, rule 5 means that frequency domain resource types can be classified by combining any one of rule 2 and any one of rule 3 and rule 4, or by combining rule 1 and rule 4. In this case, the methods for classifying frequency domain resource types include rule 5.1 to rule 5.3, where the classification criteria corresponding to each of rule 5.1 to rule 5.3 are shown in Table 10 below.

[0247] Table 10

[0248] Under the classification according to Rule 5.1, the correspondence between frequency domain resource types and whether they are operator-shared frequency domain resources, anchor frequency domain resources, and uplink frequency domain resources is shown in Table 11 below.

[0249] Table 11

[0250] The following examples, using operators A and B as examples, illustrate the correspondence between frequency domain resource types and whether they are corresponding operators and whether they are anchor frequency domain resources when classifying frequency domain resource types according to rule 5.2. Table 12 is shown below.

[0251] Table 12

[0252] It is understandable that when there are 3 or more operators and the frequency domain resource type is divided according to rule 5.2, the correspondence between the frequency domain resource type and whether it is the corresponding operator and whether it is the anchor frequency domain resource is similar to that in Table 12, and will not be repeated here.

[0253] The following examples, using operators A and B as examples, illustrate the correspondence between frequency domain resource types and whether they are corresponding operators, whether they are anchor frequency domain resources, and whether they are uplink frequency domain resources when classifying frequency domain resource types according to rule 5.3. Table 13 is shown below.

[0254] Table 13

[0255] It is understandable that when there are 3 or more operators and the frequency domain resource type is divided according to rule 5.3, the correspondence between the frequency domain resource type and whether it is the corresponding operator and whether it is the anchor frequency domain resource is similar to that in Table 13, and will not be repeated here.

[0256] In addition, the types of frequency-domain resources involved in the embodiments of this application are used for illustration. In actual implementation, the types of frequency-domain resources can also be obtained through other partitioning methods. For example, they can be partitioned according to the frequency range of the frequency-domain resources, that is, the frequency-domain resources within different frequency ranges are partitioned into different types of frequency-domain resources. For example, the spectrum resources between the frequency range F1 and the frequency range F2 are one type of frequency-domain resource, the spectrum resources between the frequency range F2 and the frequency range F3 are one type of frequency-domain resource, and the spectrum resources between the frequency range F3 and the frequency range F4 are one type of frequency-domain resource, where F1 < F2 < F3 < F4, which will not be elaborated here.

[0257] It can be understood that the values of x1, x2, x3, x4, and x5 can also be related to the application scenario. An example of cell handover is given below for illustration.

[0258] For event 1, if the channel quality of frequency-domain resource #1 satisfies the following formula (1), then enter event 1. Ms – Hys1 ≥ x1; (1)

[0259] Among them, Ms – Hys1 is equivalent to the channel quality corresponding to frequency-domain resource #1.

[0260] If the channel quality of frequency-domain resource #1 satisfies the following formula (2), then leave event 1. Ms + Hys1 < x1; (2)

[0261] Among them, Ms is the measurement result of the channel quality on frequency-domain resource #1, and Hys1 is the hysteresis parameter corresponding to event 1. Hys1 can be defined in the "report configuration information".

[0262] For event 2, if the channel quality of frequency-domain resource #1 satisfies the following formula (3), then enter event 2. Ms + Hys2 ≤ x2; (3)

[0263] Among them, Ms + Hys2 is equivalent to the channel quality corresponding to frequency-domain resource #1.

[0264] If the channel quality of frequency-domain resource #1 satisfies the following formula (4), then leave event 2. Ms + Hys2 > x2; (4)

[0265] Among them, Hys2 is the hysteresis parameter corresponding to event 2. Hys2 can be defined in the "report configuration information".

[0266] For event 3, if the channel quality of frequency-domain resource #1 and the channel quality of frequency-domain resource #2 satisfy the following formula (5), then enter event 3. Mn + Ofn + Ocn – Hys3 ≥ Mp + Ofp + Ocp + x3; (5)

[0267] Among them, Mn+Ofn+Ocn–Hys3 is equivalent to the channel quality corresponding to frequency domain resource #2, and Mp-Ofp-Ocp is equivalent to the channel quality corresponding to frequency domain resource #1.

[0268] If the channel quality of frequency domain resource #1 and the channel quality of frequency domain resource #2 satisfy the following formula (6), then leave event 3. Mn+Ofn+Ocn–Hys3 <Mp+Ofp+Ocp+x3; (6)

[0269] Where Mn is the measurement result of channel quality on frequency domain resource #2; Mp is the measurement result of channel quality on frequency domain resource #1; Ofn is the measurement object-specific offset of the reference signal of the neighboring cell (i.e., offsetMO defined in the "Measurement Configuration Information" corresponding to the neighboring cell); Ocn is the cell-specific offset of the neighboring cell (i.e., cellIndividualOffset defined in the "Measurement Configuration Information" corresponding to the neighboring cell frequency, or cellIndividualOffset defined in the reporting configuration information). If the neighboring cell is not configured, it is set to zero. Hys3 is the hysteresis parameter corresponding to event 3. Hys3 can be defined in the "Reporting Configuration Information"; Ofp is the measurement object-specific offset of the carrier in frequency domain resource #1 (i.e., offsetMO defined in the "Measurement Configuration Information" corresponding to SpCell); Ocp is the cell-specific offset of the carrier in the cell (i.e., carrierIndividualOffset defined in the "Measurement Configuration Information" corresponding to the carrier in the cell). If a carrier is not configured, Ocp is set to 0.

[0270] For event 4, if the channel quality of frequency domain resource #2 satisfies the following formula (7), then event 4 is entered: Mn+Ofn+Ocn–Hys4≥x4; (7)

[0271] Among them, Mn+Ofn+Ocn–Hys4 is equivalent to the channel quality corresponding to frequency domain resource #2.

[0272] If the channel quality of frequency domain resource #2 satisfies the following formula (8), then the departure and entry event 4 is: Mn+Ofn+Ocn+Hys4 <x4; (8)

[0273] Hys4 is the hysteresis parameter corresponding to event 4. Hys4 can be defined in "Report Configuration Information". For event 5,

[0274] If the channel quality of frequency domain resource #1 and the channel quality of frequency domain resource #2 satisfy the following formulas (9) and (10), then proceed to event 5: Mp+Hys5≤x5; (9) Mn+Ofn+Ocn–Hys5≥x6; (10)

[0275] Among them, Mp+Hys5 is equivalent to the channel quality corresponding to frequency domain resource #1, and Mn+Ofn+Ocn–Hys5 is equivalent to the channel quality corresponding to frequency domain resource #2.

[0276] If the channel quality of frequency domain resource #1 and the channel quality of frequency domain resource #2 satisfy the following formulas (11) and (12), then leave event 5: Mp+Hys5>x5; (11) Mn+Ofn+Ocn–Hys5 <x6; (12)

[0277] Hys5 is the hysteresis parameter corresponding to event 5. Hys5 can be defined in "Report Configuration Information".

[0278] The values ​​of any of Hys1, Hys2, Hys3, Hys4, and Hys5 may be the same or different.

[0279] It is understandable that in some scenarios, “≥” in any of the above formulas (1), (5), (7) and (10) can be replaced with ">”, and “≤” in the above formulas (3) or (9) can be replaced with “<”. When “≥” in formula (1) is replaced with ">”, “<” in formula (2) can also be replaced with “≤”. When “≥” in formula (5) is replaced with ">”, “<” in formula (6) can also be replaced with “≤”. When “≥” in formula (7) is replaced with ">”, “<” in formula (8) can also be replaced with “≤”. When “≥” in formula (10) is replaced with ">”, “<” in formula (12) can also be replaced with “≤”. When “≤” in formula (3) is replaced with “<”, ">” in formula (2) can also be replaced with “≥”. When “≤” in formula (9) is replaced with “<”, ">” in formula (11) can also be replaced with “≥”.

[0280] An "entry event" can refer to an event in which the channel quality meets the conditions for the event, while an "exit event" can refer to an event in which the channel quality does not meet the conditions for the event.

[0281] Optionally, if the channel quality is RSRP, then the unit of Mn and Mp is decibel milliwatt (dBm); if the channel quality is RSRQ or RS-SINR, then the unit of Mn and Mp is decibel (dB). The units of Ofn, Ocn, Hys1, Hys2, Hys3, and Hys5 are dB. The units of x1, x2, and x5 are the same as Mn. The units of x2 and x5 are the same as Mp.

[0282] The above explanation uses cell handover as an example. Similarly, for radio link management, radio link monitoring, and / or radio link recovery, the implementation of entry and exit conditions for events can refer to one or more of events 1 to 5 mentioned above, and will not be elaborated further.

[0283] Optionally, the events corresponding to the frequency domain resource type are also related to the application scenario, which includes at least one of the following: cell handover, radio link management, radio link monitoring, and / or radio link recovery. For example, under the same frequency domain resource type, the events corresponding to cell handover, radio link management, radio link monitoring, and / or radio link recovery can be the same or different. Thus, for cell handover, radio link management, radio resource management, radio link recovery, or radio link failure judgment, the communication system can design flexible measurement and reporting trigger conditions to achieve flexible processing of cell handover, radio link management, radio resource management, radio link recovery, or radio link failure judgment.

[0284] It is understood that in the embodiments of this application, when the frequency domain resource type is divided according to the frequency range, the frequency domain resources corresponding to different frequency ranges may have different values ​​of x1 to x5, and this application does not limit this.

[0285] As mentioned earlier, the first information can indicate K sets of parameters. The following further explains how the first information indicates K sets of parameters.

[0286] Optionally, the first information indicates K sets of parameters, where the kth set of parameters is used to determine the measurement reporting trigger condition corresponding to the kth frequency domain resource type among the K frequency domain resource types, and k is a positive integer less than or equal to K.

[0287] Thus, by using the first information to indicate K sets of parameters, different parameters can be configured for different frequency domain resource types, achieving flexibility in measurement reporting and reducing the processing complexity of the first communication device.

[0288] In this embodiment, a set of parameters used to determine the measurement reporting trigger condition corresponding to a frequency domain resource type corresponds to that frequency domain resource type. For example, among K sets of parameters, a set of parameters used to determine the measurement reporting trigger condition corresponding to the k-th frequency domain resource type corresponds to the k-th frequency domain resource type. Optionally, the set of parameters corresponding to the k-th frequency domain resource type includes the value of a parameter of at least one event associated with the k-th frequency domain resource type. For example, assuming the k-th frequency domain resource type is associated with event 1 and event 2, then the set of parameters corresponding to the k-th frequency domain resource type includes the value of x1 and / or the value of x2. Assuming the k-th frequency domain resource type is associated with event 1, then the set of parameters corresponding to the k-th frequency domain resource type includes the value of x1. It is understood that this embodiment uses the k-th frequency domain resource type as an example; the process is similar for each frequency domain resource type, and will not be repeated here.

[0289] Optionally, at least one of the K sets of parameters includes at least one of the following: a first threshold, a second threshold, a third threshold, a fourth threshold, a fifth threshold, or a sixth threshold.

[0290] Optionally, at least one of the K sets of parameters includes at least one of the following: the value of x1, the value of x2, the value of x3, the value of x4, or the value of x5.

[0291] In some examples, at least one set of parameters in the K sets corresponds to a frequency domain resource group or a frequency domain resource set. That is, at least one set of parameters in the K sets can be configured according to a frequency domain resource group or a frequency domain resource set. When at least one set of parameters in the K sets corresponds to a frequency domain resource group, the K sets of parameters can be configured according to the distribution of the frequency domain resource group, providing greater flexibility. A set of parameters can be configured for a frequency domain resource set, and this set of parameters can be applied to one or more frequency domain resources within the set, reducing signaling indication overhead.

[0292] Optionally, if at least one set of parameters in the K sets can be configured according to a frequency domain resource group, then in S504 above, measurement reporting can be performed according to a frequency domain resource group. It can be understood that if at least one set of parameters in the K sets can be configured according to a frequency domain resource group, measurement reporting can also be performed according to a frequency domain resource set.

[0293] Optionally, if at least one set of parameters in the K sets of parameters is configured according to frequency domain resource groups, there exists a frequency domain resource group that individually corresponds to a set of parameters in the K sets of parameters. For example, each frequency domain resource group corresponds to a set of parameters in the K sets of parameters. Alternatively, some frequency domain resource groups may each correspond to a set of parameters in the K sets of parameters, and at least one frequency domain resource set may correspond to a set of parameters in the K sets of parameters.

[0294] For example, as shown in Figure 6, assuming that the frequency domain resource set includes frequency domain resource group 0 to frequency domain resource group 3, then each of frequency domain resource group 0 to frequency domain resource group 3 corresponds to one of the K groups of parameters. For example, frequency domain resource group 0 corresponds to the first group of parameters, frequency domain resource group 1 corresponds to the second group of parameters, frequency domain resource group 2 corresponds to the third group of parameters, and frequency domain resource group 3 corresponds to the fourth group of parameters.

[0295] Optionally, if at least one set of parameters in the K sets is configured according to the frequency domain resource set, the frequency domain resource set includes one or more frequency domain resource groups, and the parameter values ​​of the same event corresponding to the one or more frequency domain resource groups can be the same.

[0296] For example, in S504 above, measurement reporting can be performed on frequency domain resource sets. For instance, as shown in Figure 7, assume that the frequency domain resource sets configured by the second communication device for the first communication device include frequency domain resource set 0, frequency domain resource set 1, and frequency domain resource set 2. Frequency domain resource set 0 includes frequency domain resources dedicated to operator A; frequency domain resource set 1 includes frequency domain resources dedicated to operator B; and frequency domain resource set 2 includes frequency domain resources shared by both operators A and B. The frequency domain resource types are classified according to the operator corresponding to the frequency domain resource set. In this case, frequency domain resource sets 0, 1, and 2 each correspond to one set of parameters from K sets of parameters. When the frequency domain resource types of frequency domain resource groups within the same frequency domain resource set are the same, the correspondence between the frequency domain resource set and the parameters can be configured.

[0297] Optionally, the first information indicates the parameters corresponding to the i-th frequency domain resource type among the K frequency domain resource types, as well as parameter information used to determine the measurement reporting trigger condition corresponding to at least one frequency domain resource type other than the i-th frequency domain resource type. In other words, the parameters corresponding to the i-th frequency domain resource type are used as reference values, and the parameters corresponding to other frequency domain resource types are based on the parameters corresponding to the i-th frequency domain resource type. The parameters corresponding to the i-th frequency domain resource type are used to determine the measurement reporting trigger condition corresponding to the i-th frequency domain resource type, where i is a positive integer less than or equal to K.

[0298] Thus, the first information indicates the parameter information of the measurement reporting trigger condition corresponding to at least one frequency domain resource type other than the i-th frequency domain resource type, such as the bias, which can reduce the amount of data in the first information and thus reduce the indication overhead.

[0299] The parameter information for the measurement reporting trigger condition corresponding to a frequency domain resource type can be the offset between the parameters of that frequency domain resource type and those of the i-th frequency domain resource type. It can be understood that the parameters corresponding to the i-th frequency domain resource type include the parameters in the event corresponding to the i-th frequency domain resource type. There can be one or more parameters corresponding to the i-th frequency domain resource type. The following example illustrates the first piece of information. Assuming K=3, where each frequency domain resource type corresponds to event 1, then the first information can indicate the value of the threshold parameter x1 corresponding to the first frequency domain resource type (e.g., x11), the offset (offset1, e.g., offset1 = x12 - x11, or offset1 = x11 - x12) between the threshold parameter x1 corresponding to the second frequency domain resource type (e.g., x12) and the value of the threshold parameter x1 corresponding to the first frequency domain resource type (e.g., x11), and the offset (offset2, e.g., offset2 = x13 - x11, or offset1 = x11 - x13) between the threshold parameter x1 corresponding to the third frequency domain resource type (e.g., x13) and the value of the threshold parameter x1 corresponding to the first frequency domain resource type.

[0300] In some implementations, the first information may also indicate the h-th parameter in the i-th frequency domain resource type, the bias of other parameters in the i-th frequency domain resource type (excluding the h-th parameter) relative to the h-th parameter, and the bias of each parameter corresponding to each frequency domain resource type (excluding the i-th frequency domain resource type) relative to the h-th parameter in the i-th frequency domain resource type.

[0301] It should be understood that for different frequency domain resource types, the corresponding values ​​of x1 may be the same or different. Similarly, the values ​​of x2 may be the same or different, the values ​​of x3 may be the same or different, the values ​​of x4 may be the same or different, and the values ​​of x5 may be the same or different.

[0302] The following examples illustrate frequency domain resource types, including frequency domain resources dedicated to operator A, frequency domain resources dedicated to operator B, and frequency domain resources shared by operators A and B. Assuming that each frequency domain resource type corresponds to at least one of events 1 to 5, the parameter values ​​for the events corresponding to each frequency domain resource type can be found in at least one row from row 2 to row 4 or at least one column from column 2 to column 5 in Table 14.

[0303] Table 14

[0304] In some examples, parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource group or set; that is, at least one set of parameters in the K groups can be configured according to a frequency domain resource group or set. When parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource group, the K groups of parameters or parameter information can be configured according to the distribution of frequency domain resources, offering greater flexibility. When parameters corresponding to at least one of the K frequency domain resource types correspond to a frequency domain resource set, parameters or parameter information can be configured for a frequency domain resource set. These parameters or parameter information can be applied to one or more frequency domain resources within the set, reducing signaling indication overhead.

[0305] In some examples, where the first information indicates the parameter information of the measurement reporting trigger condition corresponding to at least one frequency domain resource type, there exists a frequency domain resource group or frequency domain resource set whose parameter information corresponds to the measurement reporting trigger condition of the frequency domain resource type. In other words, the parameter information is configured according to the frequency domain resource group or frequency domain resource set.

[0306] For example, the parameter information for the measurement reporting trigger condition corresponding to a frequency domain resource type includes the offset between the parameters corresponding to the frequency domain resource group and the parameters corresponding to the reference frequency domain resource group. Similarly, the parameter information for the measurement reporting trigger condition corresponding to a frequency domain resource type includes the offset between the parameters corresponding to the frequency domain resource set and the parameters corresponding to the reference frequency domain resource set.

[0307] It is understood that in the embodiments of this application, the bias between two parameters is for the same type of parameter for the same event, such as x1 for event 1 when corresponding to different frequency domain resource groups.

[0308] Alternatively, the content of the first information can also be predefined by the protocol. For example, the content of the first information can be pre-configured in the first and second communication devices, i.e., no signaling indication is required.

[0309] The communication method provided by the embodiments of this application has been described in detail above with reference to Figures 5-7. The communication apparatus used to perform the communication method provided by the embodiments of this application is described in detail below with reference to Figures 8-9.

[0310] For example, FIG8 is a schematic diagram of the structure of a communication device 800 provided in an embodiment of this application. As shown in FIG8, the communication device 800 includes a processing module 801 and a transceiver module 802.

[0311] In some embodiments, the communication device 800 may be adapted to the communication system shown in FIG1 to perform the functions of the first communication device in the communication method shown in FIG5.

[0312] The transceiver module 802 is used to receive first information, which is used to determine the measurement reporting trigger conditions corresponding to K types of frequency domain resources.

[0324] It should be noted that the communication device 800 can be a network device, a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or assemblies. This communication module, circuit or chip responsible for communication functions, chip system, or other components or assemblies can be used in network devices.

[0325] Furthermore, the technical effects of the communication device 800 can be seen in the technical effects of the communication method shown in Figure 5, which will not be elaborated here.

[0326] It should be understood that when the communication device 800 is used to perform the functions of the first terminal device or the access network device, the processing module 801 involved in the communication device 800 can be implemented by a processor or processor-related circuit components, and can be a processor or processing unit; the transceiver module 802 can be implemented by a transceiver or transceiver-related circuit components or a communication interface.

[0327] For example, Figure 9 is a second schematic diagram of the structure of a communication device provided in an embodiment of this application. This communication device can be a terminal device or a network device, or it can be a chip (system) or other component or assembly that can be disposed in a terminal device or network device. As shown in Figure 9, the communication device 900 may include a processor 901. Optionally, the communication device 900 may also include a memory 902 and / or a transceiver 903. The processor 901 is coupled to the memory 902 and the transceiver 903, for example, they can be connected via a communication bus.
