Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, a communication device, and a storage medium. Background Technology

[0002] Carrier aggregation (CA) is a key technology in enhancing Long Term Evolution-Advanced (LTE-A) and 5G networks, primarily used to increase data transmission rates and system capacity. Carrier aggregation mainly achieves higher data transmission rates by aggregating multiple component carriers (CCs) to provide greater bandwidth to a single User Equipment (UE).

[0003] Taking three-component carrier aggregation (3CC) as an example, 3CC aggregation is a common application in CA. In this case, a UE 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 PCell, and the cell where the SCC is located is called the SCell.

[0004] However, current network devices only configure the triggering conditions for measurement and reporting events for the main cell, which cannot adapt to the needs of different scenarios. Summary of the Invention

[0005] This application provides a communication method, communication device, and storage medium for determining triggering conditions based on a unified carrier scenario and reporting measurement results of measurement reporting events that meet the triggering conditions, so as to realize measurement reporting based on a unified carrier scenario.

[0006] The first aspect of this application provides a communication method. The execution subject of this method can be a terminal device, a component or device applied to the terminal device (such as a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device. Taking a terminal device as an example, the terminal device receives configuration information of a measurement reporting event sent by a network device. This configuration information is used to determine the triggering condition of the measurement reporting event. The triggering condition corresponds to a unified carrier scenario, wherein the unified carrier includes multiple carriers of the same frequency band or multiple carriers of different frequency bands. If the triggering condition is met, the terminal device sends the measurement result of the measurement reporting event to the network device.

[0007] In this embodiment, the terminal device can flexibly configure triggering conditions corresponding to the scenario of the unified carrier based on the configuration information sent by the network device. The unified carrier includes multiple carriers in the same frequency band or multiple carriers in different frequency bands. Different scenarios exist for different types of unified carriers, and since the triggering conditions correspond to the scenarios of the unified carrier, corresponding triggering conditions can be configured according to different scenarios to achieve measurement event reporting for different scenario requirements.

[0008] In one possible implementation, the aforementioned scenario is a first scenario, a second scenario, or a third scenario; wherein, if the unified carrier includes multiple carriers within the same frequency band, the scenario is the first scenario;

[0009] If a unified carrier includes carriers from multiple adjacent frequency bands, then the scenario is the second scenario.

[0010] or,

[0011] If a unified carrier includes multiple carriers in different frequency bands, then the scenario is the third scenario.

[0012] In one possible implementation, if the unified carrier includes multiple carriers within the same frequency band and only includes a synchronization signal block defined by a cell, then the scenario is the first scenario.

[0013] If a unified carrier includes carriers from multiple adjacent frequency bands but only includes a synchronization signal block defined by a single cell, then the scenario is the second scenario.

[0014] or,

[0015] If a unified carrier includes multiple carriers in different frequency bands and includes at least two cell-defined synchronization signal blocks, then the scenario is the third scenario.

[0016] In one possible implementation, the aforementioned scenario is determined based on a scenario identifier in the configuration information, which is used to indicate the scenario.

[0017] Alternatively, the aforementioned scenario is determined based on the configuration information of the unified carrier.

[0018] In one possible implementation, when the aforementioned scenario is the first scenario or the second scenario, the aforementioned measurement reporting event includes one or more of the first event, the second event, the third event, the fourth event, the fifth event, the sixth event, the seventh event, the eighth event, or the ninth event.

[0019] In one possible implementation, the aforementioned configuration information includes an event triggering threshold, which includes one or more of the following: a first absolute threshold, a second absolute threshold, a third absolute threshold, a fourth absolute threshold, a fifth absolute threshold, a first offset, a first target threshold, a second target threshold, a third target threshold, a fourth target threshold, or a second offset, wherein:

[0020] The first event is triggered when the performance of the serving cell’s carrier or uniform carrier is better than the first absolute threshold. The performance of the carrier or uniform carrier is obtained by measuring the reference signal.

[0021] The second event is triggered when the performance of the serving cell's carrier or the unified carrier is worse than the second absolute threshold.

[0022] The third event is triggered when the performance of the neighboring cell's carrier is better than that of the serving cell's carrier and the first performance difference is greater than the first offset, or when the performance of the neighboring cell's unified carrier is better than that of the serving cell's unified carrier and the second performance difference is greater than the first offset.

[0023] The fourth event is triggered when the performance of the neighboring cell's carrier or the unified carrier is better than the third absolute threshold;

[0024] The fifth event is triggered when the performance of the serving cell's carrier or uniform carrier is worse than the fourth absolute threshold and the performance of the neighboring cell's carrier or uniform carrier is better than the fifth absolute threshold.

[0025] The sixth event is triggered when the performance of the serving cell's carrier or the unified carrier is better than the first target threshold.

[0026] The seventh event is triggered when the performance of the serving cell's carrier or the unified carrier is worse than the second target threshold.

[0027] The triggering condition for the eighth event is that the performance of the carrier of the neighboring cell is better than that of the carrier of the serving cell and the third performance difference is greater than the second offset, or the performance of the unified carrier of the neighboring cell is better than that of the unified carrier of the serving cell and the fourth performance difference is greater than the second offset.

[0028] The ninth event is triggered when the performance of the serving cell's carrier or uniform carrier is worse than the third target threshold and the performance of the neighboring cell's carrier or uniform carrier is better than the fourth target threshold.

[0029] In one possible implementation, when the aforementioned scenario is the third scenario, the aforementioned measurement reporting event includes one or more of the tenth, eleventh, and twelfth events.

[0030] In one possible implementation, the event triggering threshold in the aforementioned configuration information further includes one or more of a first threshold, a second threshold, a third threshold, a fourth threshold, a fifth threshold, or a sixth threshold, wherein:

[0031] The triggering condition for the tenth event is that the performance of the unified carrier of the serving cell is less than the first threshold, or the performance of the unified carrier of the neighboring cell is greater than the second threshold.

[0032] The triggering condition for the eleventh event is that at least one of the following conditions is met: the performance of the target carrier of the serving cell is less than that of the target carrier of the neighboring cell; the performance of the target carrier of the serving cell is less than that of the target carrier of the neighboring cell and the fifth performance difference is less than the third threshold; or the performance of the target carrier of the serving cell is less than the fourth threshold; the target carrier is any one of the unified carriers; and the fifth performance difference is the performance difference between the target carrier of the serving cell and the target carrier of the neighboring cell.

[0033] The triggering condition for the twelfth event is that at least one of the following conditions is met: the performance of each target carrier of the serving cell is less than the performance of the target carrier of the neighboring cell; the performance of each target carrier of the serving cell is less than the performance of the target carrier of the neighboring cell and the sixth performance difference is less than the fifth threshold; or the performance of each target carrier of the serving cell is less than the sixth threshold, where the sixth performance difference is the performance difference between the target carrier of the serving cell and the target carrier of the neighboring cell.

[0034] In one possible implementation, the method may further include: a terminal device receiving a reference signal for measuring a measurement reporting event.

[0035] In one possible implementation, the aforementioned step of the terminal device sending the measurement result of the measurement reporting event if the triggering condition is met may include: if the measurement result of the reference signal meets the triggering condition, the terminal device sends the measurement result to the network device.

[0036] In one possible implementation, when the scenario is the third scenario, a unified carrier is configured with at least two reference signals, or a carrier in one frequency band is configured with one reference signal, wherein:

[0037] The measurement results include at least two first measurement results, which are obtained by measuring the target reference signal among at least two reference signals;

[0038] Alternatively, the measurement result may include a target difference, which is the difference between two target measurement results among at least two first measurement results, or the difference between a target measurement result among at least two first measurement results and an event trigger threshold;

[0039] Alternatively, the measurement results may include N second measurement results whose performance is better than the first threshold, where N is a positive integer;

[0040] Alternatively, the measurement results may include M third measurement results whose performance is below the second threshold, where M is a positive integer.

[0041] In this embodiment, the terminal device can report one or more measurement results, and the network device can receive one or more measurement results, enabling more accurate acquisition of measurement results, facilitating subsequent resource management, and improving communication performance. Selective reporting can be achieved through reporting differences or based on a first or second threshold, reducing measurement result feedback overhead and improving communication performance.

[0042] Secondly, this application provides a communication method. Optionally, the executing entity of this method can be a second device, which can be a network device (e.g., a base station), a component or device applied to the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)). Taking a base station as an example, the base station can send configuration information for measurement reporting events to the terminal device. This configuration information is used to determine the triggering conditions for the measurement reporting events. The triggering conditions correspond to a unified carrier scenario, wherein the unified carrier includes multiple carriers of the same frequency band or multiple carriers of different frequency bands. If the base station receives the measurement result of the measurement reporting event, it performs mobility management, wherein the measurement result is obtained by measuring a reference signal.

[0043] In one possible implementation, the method may further include: the base station sending a reference signal to the terminal device, the reference signal being used for measuring measurement reporting events.

[0044] In one possible implementation, when the unified carrier in the cell includes a first carrier and a second carrier, and the first carrier and the second carrier are carriers in different frequency bands, the aforementioned motion management upon receiving the measurement result of the measurement reporting event may include: if the measurement result indicates that the performance of the first carrier is better than a first threshold and the performance of the second carrier is lower than a second threshold, then carrier reconfiguration is performed on the second carrier; if the measurement result indicates that the performance of the first carrier is lower than the first threshold and the performance of the second carrier is better than the second threshold, then carrier reconfiguration is performed on the first carrier; if the measurement result indicates that the performance of the first carrier is lower than the first threshold and the performance of the second carrier is lower than the second threshold, then cell handover is performed.

[0069] This application provides a communication method, communication device, and storage medium, which are applied in the field of communication technology. They can determine triggering conditions based on a unified carrier scenario and report the measurement results of measurement reporting events that meet the triggering conditions, so as to realize measurement reporting based on a unified carrier scenario.

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0071] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0072] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items.

[0073] First, some technical terms involved in the embodiments of this application will be introduced.

[0074] 1. Uni-carrier

[0075] A uni-carrier includes multiple carriers in the same frequency band or multiple carriers in different frequency bands. A uni-carrier includes one or more frequency domain resources.

[0076] 2. Frequency band

[0077] A frequency band can be understood as a frequency range. In other words, a frequency band corresponds to a frequency range. For example, 1880MHz-1900MHz, 2320MHz-2370MHz, and 2575MHz-2635MHz can be called a frequency band. A frequency point within a frequency band can be called a frequency point. For example, for the 1880MHz-1900MHz frequency band, 1.8GHz can be called a frequency point, or 1.8GHz can be called the dominant frequency point.

[0078] 3. Cell

[0079] A cell is a logical concept, a logical unit in a communication system that provides services to terminals. The broadcast or data signals of a cell need to be carried on a corresponding carrier for transmission. In this embodiment, one network device can correspond to multiple cells, and one cell can correspond to one network device. One cell can correspond to multiple carriers, one carrier can correspond to one cell, and one cell can correspond to a unified carrier.

[0080] Please see Figure 1a The network architecture on which the communication method in the embodiments of this application is based is briefly described below:

[0081] Figure 1a This is a schematic diagram of one possible, non-limiting system. For example... Figure 1a As shown, the communication system 1000 includes a radio access network (RAN) 100. Optionally, the communication system 1000 may also include a core network 200 and an Internet 300. RAN 100 includes at least one RAN node (e.g., Figure 1a 110a and 110b (collectively referred to as 110) and at least one terminal (such as Figure 1a RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1a(Not shown in the image). Terminal 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or via wired connection. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0082] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G, 5G, or future mobile communication system. RAN 100 can also be an open-radio access network (ORAN), a cloud-radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0083] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative, for example... Figure 1a Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices, for example... Figure 1a Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0084] In one possible scenario, access network equipment includes, but is not limited to: evolved Node B (eNodeB), radio network controller (RNC), Node B (NB), base station (BS), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenario, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be access network equipment in 5G mobile communication system. For example, a next-generation NodeB (gNB), TRP, or TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) in a base station in a 5G mobile communication system; or, access network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized units (CU), distributed units (DU), centralized unit control planes (CU-CP), centralized unit user planes (CU-UP), or radio units (RU), etc. CUs and DUs can be separate or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment, etc. For example, the access network equipment in V2X technology can be a roadside unit (RSU). It should be understood that the aforementioned TRP can be a device or module located on the network side of the aforementioned communication system and having corresponding communication functions.The TRP typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0085] Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. These can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with a wireless access network. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be called subscriber unit, subscriber station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0086] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0087] Terminals can also be drones, robots, devices in device-to-device (D2D) communication, vehicles to everything (V2X) communication, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in telemedicine or telehealth services, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0088] Furthermore, terminal devices can also be terminal devices in future communication systems beyond the fifth generation (5G) (such as 5G Advanced communication systems) or in future evolved public land mobile networks (PLMNs). For example, 5G Advanced networks can further expand the form and function of 5G communication terminals; 5G Advanced terminals include, but are not limited to, vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0089] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an open radio access network (ORAN) system, CU can also be called an open centralized unit (O-CU) or an 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). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0090] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0091] Table 1

[0092]

[0093] It should be noted that in the ORAN system, the access network equipment in this application can be one or more network elements listed in Table 1 above.

[0094] The architecture of the CU and DU of the access network equipment is described below. An access network equipment includes at least one CU and at least one DU. Optionally, the access network equipment may also include at least one RU.

[0095] The following description uses an access network device consisting of one CU and one DU as an example. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement the functions of protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0096] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0097] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0098] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices.

[0099] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0100] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0101] like Figure 1b As shown, taking a network device as a base station as an example, a base station can perform communication-related services with one or more terminal devices, and different terminal devices can also perform communication-related services.

[0102] like Figure 1c As shown, taking terminal devices including televisions and mobile phones as an example, communication-related services can also be performed between televisions and mobile phones.

[0103] Please see Figure 2 The following is a brief description of the non-terrestrial network architecture on which the communication method in the embodiments of this application is based:

[0104] Ground mobile terminals access the network via a new air interface. Network equipment is deployed on satellites and connected to the ground core network via wireless links. Simultaneously, wireless links exist between satellites to facilitate signaling interaction and user data transmission between network devices. Figure 2 The network elements and their interfaces are described below:

[0105] Terminal: Mobile devices that support the New Radio interface, typically such as mobile phones and tablets. They can access satellite networks via the air interface and initiate services such as making calls and accessing the internet.

[0106] Network equipment: mainly provides wireless access services, allocates wireless resources to access terminals, and provides reliable wireless transmission protocols and data encryption protocols, etc.

[0107] Core Network: Handles user access control, mobility management, session management, user security authentication, billing, and other services. It consists of multiple functional units, which can be divided into control plane and data plane functional entities. The Access and Mobility Management Unit (AMF) is responsible for user access management, security authentication, and mobility management. The User Plane Unit (UPF) is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0108] Ground station: Responsible for forwarding signaling and service data between satellite base stations and the core network. A ground station is a network device deployed on the ground. Ground stations used for distributing and collecting satellite communication service data, or for exchanging data within the satellite communication network and routing data to external networks, are called gateway stations. A gateway station can be a network device, a component of a network device (such as a processor, chip, or chip system), or a logic module or software that implements all or part of the functions of the network device.

[0109] New Radio: The wireless link between a terminal and a base station.

[0110] Xn interface: The interface between base stations, mainly used for signaling interaction such as handover.

[0111] NG interface: The interface between the base station and the CN, mainly used for exchanging non-access stratum (NAS) signaling of the core network and user service data.

[0112] Figure 2The terminal device in the network can be located within the beam or cell coverage area of ​​the network device. The terminal device can communicate with the network device via the uplink (UL) or downlink (DL). For example, in the UL direction, the terminal device can send uplink data to the network device via the physical uplink shared channel (PUSCH); in the DL direction, the network device can send downlink data to the terminal device via the physical downlink shared channel (PDSCH). The terminal device can be a terminal device supporting the new radio interface, which can access the network device through the air interface and initiate services such as calls and internet access. For example, the network device can be a RAN device mounted on a flight platform. When the RAN device is mounted on the flight platform, the RAN device moves synchronously with the flight platform. The RAN device and the flight platform can be considered as a single unit. In this case, the flight platform can be regarded as the RAN device, or it can be described as the flight platform operating in regenerative mode, meaning the flight platform possesses the functions of the RAN device. Additionally, the communication link between the flight platform and the terminal equipment can be referred to as a service link. When the communication system includes multiple flight platforms, the flight platforms can communicate with each other through the Xn interface. In practical applications, the network equipment can also be RAN equipment distributed on the flight platform based on DU, or it can directly serve as the flight platform; the specifics are not limited here.

[0113] The aforementioned flight platform can be a satellite, drone, or other aircraft. For example, the flight platform may include geostationary earth orbit (GEO) satellites, non-geostationary orbit satellites, low-earthorbit (LEO) satellites, medium-earth orbit (MEO) satellites, geosynchronous orbit satellites, unmanned aerial vehicle (UAV) system platforms, high altitude platform stations (HAPS), hot air balloons, or high-orbit satellites, etc., and is not specifically limited here. This application uses a satellite as the flight platform for illustration.

[0114] Low-Earth orbit (LEO) and medium-Earth orbit (MEO) satellites can have their own orbital paths, and multiple satellites typically work together to provide communication over a fixed area. High-Earth orbit (GEO) satellites are generally stationary, and one or a few high-Earth orbit satellites provide communication over a fixed area.

[0115] Furthermore, the embodiments of this application can also be applied to other future communication technologies. The network architecture and service scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of this application, and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will understand, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0116] Currently, in Long Term Evolution (LTE), a cell is typically configured with one carrier. To improve the cell's transmission rate, carrier aggregation (CA) technology can be used to combine carriers from different frequency bands into a single logical carrier, thereby enhancing the cell's data transmission capability. Furthermore, since 5G New Radio (5G NR) systems support carrier aggregation (CA) technology, in 5G NR, for a single terminal device, network equipment can be configured with multiple cells, with one cell corresponding to one carrier; that is, multiple carriers can be configured for a single terminal device.

[0117] However, in 5G NR, the triggering conditions for measurement reporting events are the same for each carrier or cell. It is not possible to configure different triggering conditions for measurement reporting events for multiple carriers in the same or different frequency bands. Therefore, how to flexibly set the triggering conditions for measurement reporting events for multiple carriers to adapt to different scenarios has become an urgent problem to be solved.

[0118] Based on this, this application proposes a communication method in which a terminal device can determine a triggering condition based on the configuration information of a measurement reporting event sent by a network device. This triggering condition corresponds to a unified carrier scenario. The unified carrier includes multiple carriers in the same frequency band or multiple carriers in different frequency bands. This allows the terminal device to determine the corresponding triggering condition based on the unified carrier scenario, flexibly adapting to different scenarios.

[0119] Please see Figure 3 One communication method in this application embodiment includes:

[0120] 301. The network device sends configuration information for measurement reporting events to the terminal device;

[0121] Typically, a terminal device can measure a reference signal based on the configuration information of the measurement reporting event sent by the network device, and report the measurement result to the network device when the measurement result meets the triggering result of the measurement reporting event, so that the network device can perform mobility management based on the measurement result.

[0122] Optionally, in addition to mobility management based on measurement results, network devices can also perform radio link management, radio resource management, radio link failure management, or radio link recovery. Mobility management includes cell handover or carrier reconfiguration.

[0123] In this embodiment of the application, the configuration information is used to determine the triggering conditions for measurement reporting events. The triggering conditions correspond to the scenario of a unified carrier, wherein the unified carrier includes multiple carriers of the same frequency band or multiple carriers of different frequency bands.

[0124] Optionally, a unified carrier may include multiple carriers within the same frequency band, multiple carriers in adjacent frequency bands, or multiple carriers in different frequency bands.

[0125] Optionally, a unified carrier can also be called a frequency domain resource set. A frequency domain resource set refers to a collection that includes one or more frequency domain resources. A frequency domain resource set can support communication of a cell on frequency domain resources in at least one frequency band. That is, a frequency domain resource set includes one or more carriers within the same frequency band, or multiple carriers within multiple frequency bands. A frequency domain resource may include one or more component carriers (CCs), in which case a frequency domain resource set may include one or more carriers.

[0126] It is understandable that the frequency domain resource set can also be called a joint carrier, carrier group, or other possible names, which are not specified here.

[0127] Optionally, a carrier can also be referred to as a frequency domain resource group, and a frequency domain resource group can include one or more frequency domain resources. A set of frequency domain resources can include one or more frequency domain resource groups.

[0128] Optionally, the frequency band in this application can be the operating band defined by the NR protocol in existing schemes, or it can be a portion of the frequency domain resources within the operating band. Furthermore, a frequency band can also refer to a segment of frequency domain resources, which may include contiguous resources or discontinuous resources.

[0129] A single frequency domain resource set can be configured using the same information or signaling. For example, it can be configured using the same system information. In a communication system, one or more frequency domain resource sets can be configured. For instance, an access network device can configure three frequency domain resource sets: set 0, set 1, and set 2. Set 0 can contain multiple frequency domain resources, set 1 can contain multiple frequency domain resources, and set 2 can contain multiple frequency domain resources. One or more frequency domain resource sets can be configured using the same information or signaling.

[0130] Optionally, frequency domain resources within the same frequency domain resource set are equivalent to a single logical carrier. For example, frequency domain resources within the same set can share a single radio frequency channel, and / or the signals carried by frequency domain resources within the same set can undergo a Fast Fourier Transform (FFT) operation together. Referring to frequency domain resource sets 0 to 2, set 0 is equivalent to a single logical carrier, set 1 is equivalent to a single logical carrier, and set 2 is equivalent to a single logical carrier. It should be understood that some frequency domain resources within the same set can also be equivalent to a single logical carrier.

[0131] Optionally, the frequency domain resource set can be divided according to the frequency band or frequency rate range where the frequency domain resources are located. Taking the frequency domain resource CC as an example, such as... Figure 4As shown, 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 commonly 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 commonly 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.

[0132] 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).

[0133] Furthermore, optionally, the multiple CCs of the UE may include anchor CCs and capacity CCs.

[0134] The anchor carrier (Anchor CC) may include at least one of the following functions: dwelling, receiving paging / LP-WUS (transmitting UL WUS), etc.

[0135] The capacity carrier (CC) can include communication functions, such as sending and receiving service data.

[0136] Anchor CC, also known as coverage CC, refers to the carrier component that ensures the basic coverage performance of the UE.

[0137] Optionally, the anchor CC and capacity CC for a UE can come from one base station or from multiple base stations.

[0138] Optionally, a Uni-carrier may include a downlink Uni-carrier and an uplink Uni-carrier. Alternatively, a Uni-carrier may include either DL resources or UL resources.

[0139] Optionally, a Uni-carrier may include a sending Uni-carrier and a receiving Uni-carrier. Alternatively, a Uni-carrier may include either a sending resource or a receiving resource.

[0140] Among them, the various types of unified carriers, such as Figure 5 As shown.

[0141] For example, in case 1, a Uni-carrier includes resources in one frequency band, such as Band 3. Band 3 is a time-domain duplex (TDD) spectrum.

[0142] For example, in case 2, a uni-carrier includes resources from two adjacent frequency bands, such as band 0 and band 1. Band 1 and band 2 are frequency domain duplex (FDD) spectrum.

[0143] For example, in case 3, a Uni-carrier includes resources in four frequency bands, such as band 0, band 1, band 2, and band 3. Band 0 and band 1 are FDD spectrum, and band 2 and band 3 are TDD spectrum.

[0144] Optionally, the configuration information may include at least one of the following: the reference signal to be measured, the time-frequency resources of the unified carrier, or the event triggering threshold, etc. The reference signal to be measured may be a synchronization signal block (SSB), a channel state information-reference signal (CSI-RS), or a reference signal used for measurement reporting, etc.

[0145] 302. The terminal device determines the triggering conditions based on the configuration information of the received measurement reporting events;

[0146] In this embodiment of the application, before determining the triggering conditions based on the configuration information, the terminal device can first determine the scenario. The scenario can be the scenario of the carrier to be measured, the spectrum to be measured, the cell to be measured, or the unified carrier to be measured.

[0147] Optionally, the measurement to be measured can refer to same-frequency measurement, different-frequency measurement, mobility measurement, target measurement, neighboring cell measurement, measurement configuration measurement, etc.

[0148] In one possible implementation, the scenario can be determined by the terminal device based on a scenario identifier in the configuration information, which is used to indicate the scenario; or, the scenario can be determined based on the configuration information of a unified carrier, wherein the configuration information of the unified carrier is used to indicate the frequency domain resource information of one or more carriers in the unified carrier.

[0149] In one possible implementation, the configuration information includes a scene identifier that indicates a scene.

[0150] Optionally, a scenario may include at least two, such as at least two of the following: a first scenario, a second scenario, and a third scenario.

[0151] In this application embodiment, the scenarios include three types: a first scenario, a second scenario, and a third scenario. Specifically, if the unified carrier includes multiple carriers within the same frequency band, the scenario is the first scenario; if the unified carrier includes multiple carriers in adjacent frequency bands, the scenario is the second scenario; and if the unified carrier includes multiple carriers in different frequency bands, the scenario is the third scenario.

[0152] Alternatively, if the unified carrier includes multiple carriers within the same frequency band and only includes a synchronization signal block defined by one cell, then the scenario is the first scenario; if the unified carrier includes multiple carriers in adjacent frequency bands and only includes a synchronization signal block defined by one cell, then the scenario is the second scenario; if the unified carrier includes multiple carriers in different frequency bands and includes at least two synchronization signal blocks defined by two cells, then the scenario is the third scenario.

[0153] Alternatively, if the unified carrier includes only one cell-defined synchronization signal block, the scenario is the first scenario or the second scenario; if the unified carrier includes at least two cell-defined synchronization signal blocks, the scenario is the third scenario.

[0154] Among them, the first scene, the second scene, and the third scene can be as follows: Figure 5 As shown.

[0155] For example, in case 1, a Uni-carrier includes resources in one frequency band, such as band 3. The Uni-carrier in case 1 includes a cell-defined-synchronization signal block (CD-SSB), which is an example of the first scenario.

[0156] For example, in case 2, a uni-carrier includes resources from two adjacent frequency bands, such as band 0 and band 1. The uni-carrier in case 2 includes a cell-defined synchronization signal block (CD-SSB), for example, the CD-SSB is in band 1. Case 2 is an example of the second scenario.

[0157] For example, in case 3, a uni-carrier includes resources in four frequency bands, such as band 0, band 1, band 2, and band 3. The uni-carrier in case 3 includes two cell-defined synchronization signal blocks (CD-SSBs), for example, the first CD-SSB in band 1 and the second CD-SSB in band 3. Therefore, case 3 is an example of the third scenario.

[0158] After determining the scenario, the terminal device can determine the measurement and reporting events based on the scenario.

[0159] In one possible implementation, when the scenario is a first scenario or a second scenario, the measurement reporting event includes one or more of the following: a first event, a second event, a third event, a fourth event, a fifth event, a sixth event, a seventh event, an eighth event, or a ninth event.

[0160] Optionally, the event triggering threshold in the aforementioned configuration information may include one or more of the following: a first absolute threshold, a second absolute threshold, a third absolute threshold, a fourth absolute threshold, a fifth absolute threshold, a first offset, a first target threshold, a second target threshold, a third target threshold, a fourth target threshold, or a second offset.

[0161] In this application embodiment, based on the first scenario or the second scenario, the triggering conditions for measurement reporting events based on the carrier level and / or the triggering conditions for measurement reporting events based on the unified carrier level can be determined according to the configuration information.

[0162] Optionally, the triggering conditions for carrier-level measurement reporting events can also be described as: the triggering conditions for frequency domain resource-level measurement reporting events based on a unified carrier, or the triggering conditions for frequency domain resource group-level measurement reporting events based on a unified carrier.

[0163] The triggering conditions for carrier-level measurement reporting events include at least one of the following:

[0164] The first event is triggered when the performance of the carrier of the serving cell is better than the first absolute threshold, and the performance of the carrier is obtained by measuring the reference signal.

[0165] The second event is triggered when the performance of the serving cell's carrier is worse than the second absolute threshold.

[0166] The third event is triggered when the performance of the neighboring cell's carrier is better than that of the serving cell's carrier and the first performance difference is greater than the first offset.

[0167] The fourth event is triggered when the performance of the neighboring cell's carrier is better than the third absolute threshold;

[0168] The fifth event is triggered when the performance of the serving cell's carrier is worse than the fourth absolute threshold and the performance of the neighboring cell's carrier is better than the fifth absolute threshold.

[0169] The sixth event is triggered when the performance of the serving cell's carrier is better than the first target threshold.

[0170] The seventh event is triggered when the performance of the serving cell's carrier is worse than the second target threshold.

[0171] The triggering condition for the eighth event is that the performance of the carrier of the neighboring cell is better than that of the carrier of the serving cell and the third performance difference is greater than the second offset.

[0172] The ninth event is triggered when the performance of the serving cell's carrier is worse than the third target threshold and the performance of the neighboring cell's carrier is better than the fourth target threshold.

[0173] In this embodiment of the application, when the performance of any carrier in the unified carrier meets the triggering conditions of a carrier-level measurement reporting event, carrier management / carrier reconfiguration can be performed on that carrier. Carrier management includes at least one of the following: activating a carrier, or deactivating a carrier. Carrier reconfiguration includes at least one of the following: deleting the carrier, updating the carrier, deactivating the carrier, activating other carriers, configuring other carriers, or adding other carriers.

[0174] The triggering conditions for measurement reporting events based on the unified carrier level include at least one of the following:

[0175] The trigger condition for the first event is that the performance of the unified carrier of the serving cell is better than the first absolute threshold, and the performance of the unified carrier is obtained by measuring the reference signal;

[0176] The second event is triggered when the performance of the uniform carrier of the serving cell is worse than the second absolute threshold.

[0177] The third event is triggered when the performance of the uniform carrier of the neighboring cell is better than that of the uniform carrier of the serving cell and the second performance difference is greater than the first offset.

[0178] The fourth event is triggered when the performance of the uniform carrier in the neighboring cell is better than the third absolute threshold.

[0179] The fifth event is triggered when the performance of the unified carrier of the serving cell is worse than the fourth absolute threshold and the performance of the unified carrier of the neighboring cell is better than the fifth absolute threshold.

[0180] The sixth event is triggered when the performance of the unified carrier of the serving cell is better than the first target threshold.

[0181] The seventh event is triggered when the performance of the uniform carrier of the serving cell is worse than the second target threshold.

[0182] The triggering condition for the eighth event is that the performance of the uniform carrier of the neighboring cell is better than that of the uniform carrier of the serving cell and the fourth performance difference is greater than the second offset.

[0183] The ninth event is triggered when the performance of the unified carrier of the serving cell is worse than the third target threshold and the performance of the unified carrier of the neighboring cell is better than the fourth target threshold.

[0184] The performance of a unified carrier can be the performance of each carrier in the unified carrier, the average performance of multiple carriers in the unified carrier, or the performance of at least one carrier in the unified carrier; the specific performance is not limited here.

[0185] For example, the entry condition of the third event can satisfy formula (1), and the exit condition of the third event can satisfy formula (2). Formulas (1) and (2) are shown below:

[0186] M n +Ofn+Ocn-Hys>M p +Ofp+Ocp+Off Formula (1)

[0187] M n +Ofn+Ocn+Hys<M p +Ofp+Ocp+Off Formula (2)

[0188] Where Mn is the measurement result of the carrier / uni-carrier in the neighboring cell, without considering any offset; Ofn is the measurement object-specific offset of the reference signal of the neighboring cell (i.e., the offset MO defined in the measObjectNR corresponding to the neighboring cell); Ocn is the cell-specific offset of the neighboring cell (i.e., the cellIndividualOffset defined in the measObjectNR corresponding to the neighboring cell frequency, or the cellIndividualOffset defined in reportConfigNR), which is set to zero if the neighboring cell is not configured; Mp is the measurement result of the carrier / uni-carrier in the serving cell, without considering any offset; Ofp is the measurement result of the carrier / uni-carrier in the serving cell. r is the object-specific offset of the measurement (i.e., offsetMO defined in measObjectNR for SpCell); Ocp is the cell-specific offset of the carrier / Uni-carrier in the serving cell (i.e., carrierIndividualOffset defined in measObjectNR for the carrier / Uni-carrier in the serving cell). If a carrier / Uni-carrier is not configured, Ocp is set to 0; Hys is the hysteresis parameter for this event (i.e., the hysteresis defined for this event in reportConfigNR); Off is the offset parameter for this event (i.e., a3-Offset defined for this event in reportConfigNR).

[0189] For example, the entry condition of the fifth event can satisfy formula (3) and formula (4), and the exit condition of the fifth event can satisfy formula (5) and formula (6). Formulas (3), (4) and formulas (5), (6) are shown below:

[0190] M p +Hys<Fourth Absolute Threshold Formula (3) M n +Ofn+Ocn-Hys>Fifth Absolute Threshold Formula (4)

[0191] M p -Hys>Fourth Absolute Threshold Formula (5) M n +Ofn+Ocn+Hys<Fifth Absolute Threshold Formula (6)

[0192] The entry condition for the sixth event satisfies formula (7), and the exit condition for the sixth event satisfies formula (8). Formulas (7) and (8) are shown below:

[0193] M s -Hys>First Target Threshold Formula (7) M s +Hys < First target threshold formula (8)

[0194] The entry condition for the seventh event satisfies formula (9), and the exit condition for the seventh event satisfies formula (10). Formulas (9) and (10) are shown below:

[0195] M s +Hys<Second Target Threshold Formula (9) M s -Hys>Second Target Threshold Formula (10)

[0196] The entry condition for the eighth event satisfies formula (11), and the exit condition for the eighth event satisfies formula (12). Formulas (11) and (12) are shown below:

[0197] M n +Ofn+Ocn-Hys>M p +Ofp+Ocp+Off Formula (11)

[0198] M n +Ofn+Ocn+Hys<M p +Ofp+Ocp+Off Formula (12)

[0199] The entry condition for the ninth event can satisfy formulas (13) and (14), and the exit condition for the ninth event can satisfy formulas (15) and (16). Formulas (13), (14) and (15), (16) are shown below:

[0200] M p +Hys<Third target threshold formula (13) M n +Ofn+Ocn-Hys>Fourth objective threshold formula (14)

[0201] M p -Hys>Third Target Threshold Formula (15) M n +Ofn+Ocn+Hys<Fourth objective threshold formula (16)

[0202] In one possible implementation, when the scenario is the third scenario, the measurement reporting event includes one or more of the tenth, eleventh, and twelfth events.

[0203] Optionally, the event triggering threshold in the aforementioned configuration information may also include one or more of the following: a first threshold, a second threshold, a third threshold, a fourth threshold, a fifth threshold, or a sixth threshold.

[0204] Based on the third scenario, the triggering conditions for measurement reporting events include at least one of the following:

[0205] The triggering condition for the tenth event is that the performance of the unified carrier of the serving cell is less than the first threshold, or the performance of the unified carrier of the neighboring cell is greater than the second threshold.

[0206] The triggering condition for the eleventh event is that at least one of the following conditions is met: the performance of the target carrier of the serving cell is less than that of the target carrier of the neighboring cell; the performance of the target carrier of the serving cell is less than that of the target carrier of the neighboring cell and the fifth performance difference is less than the third threshold; or the performance of the target carrier of the serving cell is less than the fourth threshold; the target carrier is any one of the unified carriers; and the fifth performance difference is the performance difference between the target carrier of the serving cell and the target carrier of the neighboring cell.

[0207] The triggering condition for the twelfth event is that at least one of the following conditions is met: the performance of each target carrier of the serving cell is less than the performance of the target carrier of the neighboring cell; the performance of each target carrier of the serving cell is less than the performance of the target carrier of the neighboring cell and the sixth performance difference is less than the fifth threshold; or the performance of each target carrier of the serving cell is less than the sixth threshold, where the sixth performance difference is the performance difference between the target carrier of the serving cell and the target carrier of the neighboring cell.

[0208] Optionally, embodiments of this application further include step 301a: the network device sending a reference signal to the terminal device;

[0209] In one possible implementation, the configuration information of the reference signal may be included in the configuration information of the measurement reporting event. The reference signal is sent to the terminal device by one or more network devices. These one or more network devices may or may not include the network device sending the configuration information. Similar to step 301 above, the reference signal is used to measure the measurement reporting event. Furthermore, the performance of the carrier or the uniform carrier can be determined by measuring the reference signal. The reference signal may be a synchronization signal block (SSB), a channel state information-reference signal (CSI-RS), or a reference signal used for measurement reporting, etc.

[0210] Optionally, this application embodiment further includes step 302a: if the triggering condition is met, the terminal device sends the measurement result to the network device; correspondingly, the network device receives the measurement result.

[0211] Typically, network devices send reference signals to terminal devices so that the terminal devices can measure the reference signals and determine whether the result meets the triggering conditions for the aforementioned measurement reporting event. When the measurement result of the reference signal meets the triggering conditions, the terminal device sends the measurement result to the network device.

[0212] In one possible implementation, when the scenario is the third scenario, a unified carrier is configured with at least two reference signals, or a carrier in a frequency band is configured with one reference signal. In this case, the terminal device reports the measurement results to the network device in at least one of the following ways:

[0213] The measurement results include at least two first measurement results, which are obtained by measuring the target reference signal among at least two reference signals;

[0214] Alternatively, the measurement result may include a target difference, which is the difference between two target measurement results among at least two first measurement results, or the difference between a target measurement result among at least two first measurement results and an event trigger threshold;

[0215] Alternatively, the measurement results may include N second measurement results whose performance is better than the first threshold, where N is a positive integer;

[0216] Alternatively, the measurement results may include M third measurement results whose performance is below the second threshold, where M is a positive integer.

[0217] The measurement results include N second measurement results whose performance is better than the first threshold. That is, one or more measurement results with better performance (or better than the first threshold) can be reported. For example, when the measurement result is the signal-to-interference-plus-noise ratio (RS-SINR), the measurement results with RS-SINR values ​​greater than the first threshold are reported.

[0218] Optionally, the measurement results can be reference signal received power (RSRP), reference signal received quality (RSRQ), reference signal-to-interference-plus-noise ratio (RS-SINR), channel quality indicator (CQI), or received signal strength indicator (RSSI).

[0219] Optionally, this application embodiment also includes step 302b: if the network device receives the measurement result of the measurement reporting event reported by the terminal device, then it performs mobility management.

[0220] Network devices can perform mobility management based on measurement results, as well as radio link management, radio resource management, radio link failure handling, or radio link recovery. Mobility management includes cell handover, carrier management, or carrier reconfiguration.

[0221] Optionally, when the unified carrier in the cell includes a first carrier and a second carrier, and the first carrier and the second carrier are carriers in different frequency bands, if the measurement results indicate that the performance of the first carrier is better than the first threshold and the performance of the second carrier is lower than the second threshold, then the network device performs carrier reconfiguration on the second carrier.

[0222] If the measurement results indicate that the performance of the first carrier is lower than the first threshold and the performance of the second carrier is better than the second threshold, then carrier reconfiguration is performed on the first carrier;

[0223] If the measurement results indicate that the performance of the first carrier is lower than the first threshold and the performance of the second carrier is lower than the second threshold, then the cell is switched over.

[0224] For example, such as Figure 6 As shown, Figure 6 The f1 carrier is a sub-1GHz frequency band, such as 700MHz, 800MHz, or 900MHz. The f2 carrier is a 1.8GHz or 2.6GHz frequency band. f1 offers wider coverage at lower frequencies, while f2 offers less coverage. The network devices corresponding to f1 and f2 can be in co-located or non-co-located scenarios. A co-located scenario means that the network devices corresponding to f1 and f2 are the same, while a non-co-located scenario means that the network devices corresponding to f1 and f2 are not the same.

[0225] When a user is moving, if the performance of f1 is good (or the performance of f1 is better than the first threshold) and the performance of f2 deteriorates (or the performance of f2 is lower than the second threshold), then the f2 carrier can be reconfigured; if the performance of f1 deteriorates (or the performance of f1 is lower than the second threshold) and the performance of f2 is good (or the performance of f2 is better than the first threshold), then the f1 carrier can be reconfigured; when the performance of both f1 and f2 deteriorates, cell handover can be performed.

[0226] For example, such as Figure 7 As shown, Figure 7The f1 carrier is a sub-1GHz frequency band, such as 700MHz, 800MHz, or 900MHz. The f2 carrier is a 1.8GHz or 2.6GHz frequency band. f1 offers wider coverage at lower frequencies, while f2 offers less coverage. The network devices corresponding to f1 and f2 can be used in co-location scenarios.

[0227] When a user is moving and in an area without f2 coverage, f2 carrier silence can be implemented, meaning no measurements or transmissions are performed. Upon returning to an f2 coverage area, f2 carrier reconfiguration or remeasurement can be performed. If f1 performance is good but f2 performance deteriorates, f2 carrier reconfiguration can be performed; if f1 performance deteriorates but f2 performance is good, f1 carrier reconfiguration can be performed; if both f1 and f2 performance deteriorates, cell handover can be performed.
