Description

Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202411626779.8, filed on November 13, 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 communication methods and communication devices. Background Technology

[0003] In a multi-layer network scenario, a cell can have multiple frequency points, and network devices can schedule these multiple frequency points within a cell. Since low-frequency frequencies provide camping and access-related services, they can be called camping layer frequencies. Since high-frequency frequencies provide capacity transmission services, they can be called capacity layer frequencies. Terminals can receive paging messages or wake-up signals through camping frequencies when idle or inactive, and perform data transmission through capacity frequencies when connected.

[0004] Network devices can manage multiple capacity frequency points, and the choice of which capacity frequency point a terminal uses for data transmission is determined by the network device. Since network devices are unsure whether the configured capacity frequency point is reasonable or suitable for the terminal's communication environment, inappropriate capacity frequency point configuration can lead to low data transmission efficiency. Therefore, ensuring or improving the efficiency of terminal data transmission is a pressing technical problem that needs to be solved. Summary of the Invention

[0005] This application provides a communication method and a communication device, which helps to ensure or improve the efficiency of terminal data transmission.

[0006] Firstly, this application provides a communication method that can be executed by a terminal. Here, "terminal" (or "terminal device") can refer to the terminal itself, or to a processor, module, chip, or chip system within the terminal that implements the method. The method includes: the terminal receiving configuration information indicating M capacity frequency points and M first measurement events corresponding to each of the M capacity frequency points; the terminal measuring a reference signal for each of the M capacity frequency points to obtain the signal quality of each of the M capacity frequency points; and, upon satisfying a first measurement event, the terminal sending first information. Wherein, the capacity frequency points are used for data transmission, the first information indicates the capacity frequency point corresponding to the first measurement event, and M is an integer greater than 1.

[0007] Based on the method described in the first aspect, when the terminal meets the first measurement event at the capacity frequency point, it reports the capacity frequency point that meets the first measurement event to the network device through the first information, so that the network device can determine the signal quality of the capacity frequency point through the first information, and enable the network device to subsequently configure a capacity frequency point with better signal quality for the terminal, thereby ensuring or improving the efficiency of terminal data transmission.

[0008] In one possible implementation, the first measurement event corresponding to the first capacity frequency point includes one or more of the following events:

[0009] Event A: The signal quality at the first capacity frequency point is greater than the first threshold; or,

[0010] Event B: The signal quality at the first capacity frequency point is less than the second threshold; or,

[0011] Event C: The signal quality of the first capacity frequency point is less than the third threshold, and the signal quality of the second capacity frequency point is greater than the fourth threshold.

[0012] Event A is the condition for the terminal to transmit data at the first capacity frequency point, event B is the condition for the terminal to stop transmitting data at the first capacity frequency point, and event C is the condition for the terminal to switch from the first capacity frequency point to the second capacity frequency point for data transmission. The first capacity frequency point is one of the M capacity frequency points, and the second capacity frequency point is the other capacity frequency points among the M capacity frequency points besides the first capacity frequency point.

[0013] In this implementation, when the terminal meets the conditions for data transmission, data transmission cessation, or switching at the first capacity frequency point, it can send first information indicating the first capacity frequency point to the network device. This allows the network device to configure the terminal to transmit data on the first capacity frequency point, stop transmitting data on the first capacity frequency point, or switch to the second capacity frequency point for data transmission based on the first measurement event corresponding to the first information. This helps to ensure or improve the data transmission efficiency of the terminal.

[0014] In one possible implementation, the configuration information further indicates L camping frequency points and the second measurement events corresponding to each of the L camping frequency points, where L is an integer greater than or equal to 1. The method also includes: the terminal measuring the reference signal corresponding to each of the L camping frequency points to obtain the signal quality of each of the L camping frequency points; and when the second measurement event is satisfied, the terminal sending second information. The second information indicates the camping frequency point corresponding to the second measurement event. With this implementation, when a camping frequency point satisfies the second measurement event, the terminal reports the capacity frequency point that satisfies the second measurement event to the network device via the second information. This allows the network device to determine the signal quality of the camping frequency point through the second information, which is beneficial for the network device to subsequently configure a capacity frequency point with better signal quality for the terminal, thus ensuring or improving the terminal's communication quality.

[0015] In one possible implementation, there is a correlation between the L stationary frequency points and the M capacity frequency points. Optionally, the relationship between the stationary frequency points and the capacity frequency points can be one-to-one, one-to-many, many-to-one, or many-to-many.

[0016] In one possible implementation, the first cycle is shorter than the second cycle, where the first cycle is the cycle for reporting the first information and the second cycle is the cycle for reporting the second information. A higher frequency at which the terminal reports the first information to the network device is more beneficial for the network device to obtain the signal quality status of the capacity frequency point more promptly, thereby configuring an appropriate capacity frequency point for the terminal and ensuring the terminal's data transmission efficiency.

[0017] In one possible implementation, the first information also indicates the identifier of the camping frequency point accessed by the terminal. Optionally, the capacity frequency point indicated by the first information may be associated with multiple camping frequencies, or there may be no pre-agreed association between the capacity frequency point and the camping frequency point. In this way, network devices can determine the location of the terminal through the camping frequency point, and when paging the terminal is required, paging can be performed without being conducted within the tracking area (TA) and radio access network notification area (RNA).

[0018] In one possible implementation, upon satisfying a first measurement event, the terminal sends first information, including: when the first measurement events corresponding to the N capacity frequency points are satisfied respectively, the terminal sends N pieces of first information. Here, the N capacity frequency points belong to M capacity frequency points. The method further includes: the terminal receiving third information, the third information indicating data transmission on one or more of the N capacity frequency points. Here, N is an integer greater than or equal to 1. Optionally, the N capacity frequency points are capacity frequency points among the M capacity frequency points whose signal quality is greater than a threshold value. Alternatively, the N capacity frequency points are the N capacity frequency points with the best signal quality among the M capacity frequency points, where the N capacity frequency points with the best signal quality refer to those where the signal quality of each of the N capacity frequency points is higher than that of other capacity frequency points among the M capacity frequency points excluding the N capacity frequency points. Using this method, the terminal can perform data transmission on the capacity frequency points indicated by the third information, improving data transmission efficiency.

[0019] In one possible implementation, the third information is carried on at least one of the following: a wake-up signal (WUS), a chirp signal, downlink control information (DCI), or a system message. For example, the WUS signal is used to wake up the terminal; the chirp signal is a frequency-modulated signal whose frequency can change over time; the DCI can be used to schedule downlink data transmission or to schedule the downlink data channel; and the system message can be used to transmit system-level information, such as cell configuration information, system parameters, or system functions.

[0020] Secondly, this application provides a communication method that can be executed by a network device. This network device (or network apparatus) can refer to the network device itself, or to a processor, module, chip, or chip system within the network device that implements the method. The method includes: the network device sending configuration information; sending a reference signal on each of the M capacity frequency points indicated by the configuration information; and receiving N first pieces of information. The configuration information indicates the M capacity frequency points and the M first measurement events corresponding to each of the M capacity frequency points. The capacity frequency points are used for data transmission, M is an integer greater than 1, and the N first pieces of information respectively indicate the N capacity frequency points, which belong to the M capacity frequency points. N is an integer greater than or equal to 1.

[0021] In one possible implementation, the first measurement event corresponding to the first capacity frequency point includes one or more of the following events:

[0022] Event A: The signal quality at the first capacity frequency point is greater than the first threshold; or,

[0023] Event B: The signal quality at the first capacity frequency point is less than the second threshold; or,

[0024] Event C: The signal quality of the first capacity frequency point is less than the third threshold, and the signal quality of the second capacity frequency point is greater than the fourth threshold.

[0025] Event A is the condition for the terminal to transmit data at the first capacity frequency point, event B is the condition for the terminal to stop transmitting data at the first capacity frequency point, and event C is the condition for the terminal to switch from the first capacity frequency point to the second capacity frequency point for data transmission. The first capacity frequency point is one of the M capacity frequency points, and the second capacity frequency point is the other capacity frequency points among the M capacity frequency points besides the first capacity frequency point.

[0026] In one possible implementation, the configuration information further indicates L camping frequency points and the second measurement events corresponding to each of the L camping frequency points, where L is an integer greater than or equal to 1. The method also includes: the network device transmitting a reference signal on each of the L camping frequency points; and the network device receiving K pieces of second information, each of the K pieces of second information indicating a different K camping frequency point, where the K camping frequency points belong to the L camping frequency points, and K is an integer greater than or equal to 1.

[0027] In one possible implementation, there is a correlation between the L resident frequency points and the M capacity frequency points.

[0028] In one possible implementation, the first cycle is shorter than the second cycle, where the first cycle is the cycle for reporting the first piece of information and the second cycle is the cycle for reporting the second piece of information.

[0029] In one possible implementation, the first information also indicates the identifier of the stationing frequency point accessed by the terminal.

[0030] In one possible implementation, the M capacity frequency points are determined based on at least one parameter among Quality of Service (QoS), terminal capabilities, or data services. This ensures that each of the M capacity frequency points configured for the terminal by the network device satisfies or is compatible with at least one of the terminal's QoS, terminal capabilities, or data services, thereby improving the terminal's data transmission efficiency.

[0031] In one possible implementation, the method further includes: the network device sending third information indicating data transmission on one or more of the N capacity frequency points. Using this method, the network device transmits data on the capacity frequency point indicated by the third information, thereby improving data transmission efficiency.

[0032] In one possible implementation, the third information is carried on at least one of the following: a WUS signal, a chirp signal, a DCI signal, or a system message.

[0033] Thirdly, embodiments of this application provide a communication device for executing the method in any possible implementation of either the first or second aspect. The communication device includes modules for executing the method in any possible implementation of either the first or second aspect.

[0034] Fourthly, embodiments of this application provide a communication device including a processing circuit for executing a method in any possible implementation of either the first or second aspect. The processing circuit executes a program, and when the program is executed, the method described in any possible implementation of either the first or second aspect is performed.

[0035] In one possible implementation, the communication device further includes a memory for storing the program.

[0036] In one possible implementation, the memory is located outside the aforementioned communication device.

[0037] In one possible implementation, the memory is located within the aforementioned communication device.

[0038] Furthermore, the processing circuitry and memory can be integrated into a single device; that is, the processing circuitry and memory can be combined. For example, the communication device can be a chip.

[0039] In one possible implementation, the communication device further includes a transceiver circuit for receiving information (or inputting information) or sending information (or outputting information).

[0067] The following describes the communication system involved in the embodiments of this application.

[0068] The technical solutions provided in this application can be applied to various communication systems, such as: 5th generation (5G) or new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, wireless local area network (WLAN) systems, satellite communication systems, future communication systems, or integrated systems of multiple systems. The technical solutions provided in this application can also be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and Internet of Things (IoT) communication systems or other communication systems.

[0069] The method provided in this application can be applied between two entities in a communication system, such as one entity sending information to or receiving information sent by the other entity. In a wireless communication system, communication devices are included, and these devices can communicate wirelessly using air interface resources. Air interface resources may include at least one of time-domain resources, frequency-domain resources, code resources, and spatial resources; this application does not limit this. For example, the aforementioned two entities may include a network device and a terminal device, or may include a chip that can be placed in a network device and a chip that can be placed in a terminal device, etc. Of course, as standards advance, other types of entities may emerge subsequently; this application does not limit this.

[0070] Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. In Figure 1, the communication system includes network devices and terminals. The terminal can be located within the coverage area of ​​one or more cells provided by the network device (such as cell 1 and cell 2 in Figure 1), and the number of cells serving the terminal can be one or more, that is, the number of serving cells can be one or more.

[0071] When there are multiple serving cells, the terminal communicates based on carrier aggregation (CA), dual connectivity (DC), or cooperative multipoint transmission methods. When the terminal moves, it can select or hand over cells between different cells, which can be distributed under a single network device, i.e., co-located deployment. For example, as shown in Figure 1(a), network device 1 manages cells 1 and 2. Alternatively, different cells can be distributed under different network devices, i.e., not co-located (or cross-site). For example, as shown in Figure 1(b), network device 1 manages cell 1, and network device 2 manages cell 2. This application does not limit this.

[0072] Optionally, the number of network devices and terminals in Figure 1 is merely illustrative and should not be considered a specific limitation of this application. In specific implementations, the communication system may include fewer or more network devices, and the coverage area of ​​each network device may include more or fewer terminal devices; this application does not limit this. The architecture shown in Figure 1 is merely an example and does not impose limitations on the network architecture applicable to this application. Any network architecture that allows communication between a network device and a terminal device is applicable to this application.

[0073] The following provides a detailed description of the terminals and network devices.

[0074] A terminal is a device with wireless transceiver capabilities, also known as a terminal device. A terminal can communicate with access network equipment (or access devices, or network devices as described below) in a radio access network (RAN). A terminal can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device, etc. In one possible implementation, the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or it can be deployed on water, including ships; or it can be deployed in the air, such as on airplanes, balloons, or satellites. In another possible implementation, the terminal can be a handheld device with wireless communication capabilities, vehicle-mounted device, wearable device, sensor, terminal in the Internet of Things (IoT), terminal in the Internet of Vehicles (IoV), drone, or any form of terminal in a 5G network or future network, etc., and this application embodiment does not limit this. In another possible implementation, the terminal can also be a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc.

[0075] In this application embodiment, the device for implementing the terminal's functions can be a terminal itself; it can also be a device capable of supporting the terminal in implementing those functions, such as a chip system. This device can be installed in the terminal or used in conjunction with the terminal. In this application embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. For ease of description, the technical solutions provided in this application embodiment will be described below using a UE as an example when referring to some examples.

[0076] A network device can be a device deployed in a wireless access network to provide wireless communication services to terminals. This network device can also be called an access network device, access equipment, or RAN device, etc. For example, a network device can be a next-generation node B (gNB), a next-generation evolved node B (ng-eNB), or a network device in future communications. A network device can be any device with wireless transceiver capabilities, including but not limited to the base stations mentioned above (including base stations deployed on satellites). This network device can also be a device with base station functionality in future communication systems. As an example, this network device can be an access node, wireless relay node, or wireless backhaul node in a wireless-fidelity (Wi-Fi) system. As another example, this network device can be a wireless controller in a cloud radio access network (CRAN) scenario. As yet another example, this network device can be a wearable device or vehicle-mounted device capable of providing wireless communication services. As yet another example, this network device can also be a small cell, a transmission reception point (TRP) (or a transmit-receive node), etc. In systems using different wireless access technologies, the names of devices with network equipment functions may vary, and these will not be listed one by one in the embodiments of this application.

[0077] Network devices can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, a helicopter or drone can be configured to be used as a device to communicate with another network device.

[0078] In some network device deployments, the network device may include a central unit (CU) and a distributed unit (DU). For example, some protocol layer functions of the network device may be centrally controlled by the CU, while the remaining part or all of the protocol layer functions may be distributed in the DU, which is centrally controlled by the CU. In other network device deployments, the CU may be divided into a CU-control plane (CP) and a CU-user plane (UP). In still other network device deployments, the network device may also be an open radio access network (ORAN) architecture. When the network device is an ORAN architecture, it may be a functional entity or module within the ORAN. For example, the network device may be one or more of a CU, DU, or RU. In an ORAN system, the CU may also be called an open (O)-CU, the DU may also be called an O-DU, the CU-CP may also be called an O-CU-CP, and the CU-UP may also be called an O-CU-UP, etc. The network device deployment methods listed here are merely examples. As standard technologies evolve, network devices may have other deployment forms, and this application does not limit these.

[0079] In some deployments, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes each implementing a portion of the access network's functions. For example, RAN nodes can be CUs, DUs, CU-CPs, CU-UPs, or RUs. CUs and DUs can be configured separately or included in the same network element, such as an indoor baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0080] RAN nodes can support one or more types of fronthaul interfaces, each corresponding to a DU and RU with different functions. If the fronthaul interface between the DU and RU is a Common Public Radio Interface (CPRI), the DU is configured to implement one or more baseband functions, and the RU is configured to implement one or more radio frequency functions. If the fronthaul interface between the DU and RU is another type of interface, relative to CPRI, it moves some downlink and / or uplink baseband functions—for example, for downlink, precoding, or one or more of inverse fast Fourier transform (IFFT) / adding a cyclic prefix (CP)—from the DU to the RU; and for uplink, digital beamforming, or one or more of fast Fourier transform (FFT) / removing CP—from the DU to the RU. In one possible implementation, this interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the partitioning methods between DU and RU are different, corresponding to different types (category, Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0081] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0082] Network devices and / or terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminals are located. Furthermore, terminals and network devices can be hardware devices, software functions running on dedicated hardware, or software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminals and network devices.

[0083] In this embodiment, the device for implementing the functions of the network device can be the network device itself; or it can be a device capable of supporting the network device in implementing the functions, such as a chip system. This device can be installed in the network device or used in conjunction with the network device.

[0084] The following explains the relevant terms used in the embodiments of this application:

[0085] I. Frequency

[0086] A frequency point refers to a segment of resources on a frequency band, or it can also be called a carrier, carrier group, frequency range, or frequency bandwidth.

[0087] 5G communication systems define two frequency ranges: FR1, also known as Sub-6 GHz (GHz), which includes frequencies below 6 GHz, and FR2, known as millimeter wave, which includes frequencies above 6 GHz. The system bandwidth and subcarrier spacing differ for each frequency range. FR1, with its lower frequency, offers better coverage, while FR2, with its higher frequency, provides greater bandwidth and capacity. In practical network deployment, considering both coverage and capacity, multi-frequency co-deployment can be adopted. For example, cells within FR1 and cells within FR2 can be deployed simultaneously in the same area.

[0088] Among them, a frequency point within FR1 can be called a low-frequency frequency point. A frequency point within FR2 can be called a high-frequency frequency point. Optionally, in this application, the way to distinguish between low-frequency and high-frequency frequencies is not limited to the two frequency point ranges defined by the 5G communication system. Any two frequency points with relatively high and low frequencies can be understood as low-frequency and high-frequency frequencies, that is, low-frequency and high-frequency frequencies are relative concepts.

[0089] A cell can have one or more frequency points. When a cell has only one frequency point, switching cells is equivalent to switching the operating frequency point. In a multi-layer network, a cell can have multiple frequency points, and these multiple frequency points can be uniformly scheduled within a single cell.

[0090] Low-frequency frequencies offer better coverage and can be used to provide network coverage. Optionally, the coverage area of ​​a stationary frequency point can be larger than that of a capacity frequency point. Terminals in idle or inactive states can receive paging messages and / or wake-up signals (WUS) on the stationary frequency point. The wake-up signal, also known as a low-power wake-up signal (LP-WUS), is a signal with wake-up functionality. For example, a wake-up signal can be used to wake up a single device or a group of devices, triggering the corresponding terminal to perform certain operations, including but not limited to updating system messages, receiving paging messages, initiating random access, and receiving disaster warning information—at least one of these. Therefore, low-frequency points can be referred to as stationary layer points, stationary points, overlay layer points, or basic layer points. These expressions can be used interchangeably, and the specific naming does not limit the scope of protection of this application. For ease of description, the term stationary point will be used in a detailed description below. Since a frequency point can be a carrier, a stationary point can also be a stationary carrier, a low-frequency carrier, an anchor carrier (anchor CC), an overlay layer carrier, a basic layer carrier, or a basic component carrier (BCC).

[0091] High-frequency frequencies have higher frequencies, larger bandwidths, and greater capacity. They can be used for data transmission. Active terminals can transmit data with network devices on capacity frequencies. Therefore, high-frequency frequencies can be called capacity layer frequencies or capacity frequencies; these two expressions are interchangeable, and the specific naming does not limit the scope of protection of this application. For ease of description, the term "resident frequency" will be used uniformly below. Since a frequency can be a carrier, a capacity frequency can be called a capacity layer carrier, capacity carrier, high-frequency carrier, or data component carrier (DCC).

[0092] A cell can have one or more frequency points. When a cell has only one frequency point, switching cells is equivalent to switching the operating frequency point. In a multi-layer network, a cell can have multiple frequency points, and these multiple frequency points can be uniformly scheduled within a single cell.

[0093] Network devices can manage multiple capacity frequency points, and the choice of which capacity frequency point a terminal uses for data transmission is determined by the network device. Since the network device is unsure whether its configured capacity frequency point is reasonable or suitable for the terminal's communication environment, the terminal may experience low data transmission efficiency when the network device configures an unreasonable capacity frequency point. To ensure or improve the terminal's data transmission efficiency, this application proposes a communication method whereby, when a capacity frequency point meets a measurement event, the terminal reports the capacity frequency point to the network device. This allows the network device to configure a capacity frequency point with higher signal quality for data transmission, thus helping to ensure or improve the terminal's data transmission efficiency. As shown in Figure 2, this communication method includes steps 201 to 203. The method shown in Figure 2 is applied between a terminal and a network device. The terminal can be the terminal itself, or a processor, module, chip, chip system, or functional module implementing the method. The network device can be the network device itself, or a processor, module, chip, chip system, or functional module implementing the method.

[0094] 201. The network device sends configuration information, which indicates M capacity frequency points and M first measurement events corresponding to the M capacity frequency points.

[0095] Correspondingly, the terminal receives configuration information. Here, M is an integer greater than 1.

[0096] There is a one-to-one correspondence between the M capacity frequency points and the M first measurement events. The first measurement event is used to trigger the terminal to report first information, and the first information is used to indicate the capacity frequency point corresponding to the first measurement event. For example, the M capacity frequency points include the first capacity frequency point. When the first capacity frequency point satisfies the first measurement event, the terminal sends the first information, which indicates the first capacity frequency point.

[0097] 202. The network device transmits a reference signal on each of the M capacity frequency points.

[0098] Correspondingly, the terminal measures the reference signal corresponding to each of the M capacity frequency points to obtain the signal quality of each of the M capacity frequency points. The reference signal can be used by the terminal to perform measurements to determine whether the capacity frequency point meets the first measurement event.

[0099] Optionally, the reference signal may include one or more of the following reference signals: channel state information-reference signal (CSI-RS), tracking reference signal (TRS), demodulation reference signal (DMRS), or sounding reference signal (SRS).

[0100] In some possible implementations, the configuration information further indicates M measurement resources corresponding to the M capacity frequency points. These M measurement resources are time-domain and / or frequency-domain resources used to transmit reference signals for the M capacity frequency points. Each of the M capacity frequency points corresponds one-to-one with one of the M measurement resources. For example, the M capacity frequency points include a first capacity frequency point and a second capacity frequency point. The configuration information also indicates the first and second measurement resources, which correspond to each other. The terminal can measure the reference signal on the first measurement resource to obtain the signal quality of the first capacity frequency point, and measure the reference signal on the second measurement resource to obtain the signal quality of the second capacity frequency point. Optionally, the measurement resources include the time-domain and / or frequency-domain resources occupied by the reference signal. By configuring the M measurement resources corresponding to the M capacity frequency points for the terminal through the network device, the terminal can obtain the signal quality of each of the M capacity frequency points by measuring the reference signal on each of the M measurement resources, which helps improve the accuracy of the measurement results.

[0101] The following description uses the first capacity frequency point as an example to illustrate the first measurement event corresponding to the first capacity frequency point. The first measurement event corresponding to the first capacity frequency point may include one or more of the following events:

[0102] Event A: The signal quality at the first capacity frequency point is greater than the first threshold; or,

[0103] Event B: The signal quality at the first capacity frequency point is less than the second threshold; or,

[0104] Event C: The signal quality of the first capacity frequency point is less than the third threshold, and the signal quality of the second capacity frequency point is greater than the fourth threshold.

[0105] Event A is the condition for the terminal to transmit data on the first capacity frequency point, event B is the condition for the terminal to stop transmitting data on the first capacity frequency point, and event C is the condition for the terminal to switch from the first capacity frequency point to the second capacity frequency point for data transmission. The second capacity frequency point is any of the M capacity frequency points other than the first capacity frequency point.

[0106] The signal quality of the first capacity frequency point is the signal quality obtained by the terminal measuring the reference signal at the first capacity frequency point. The higher the signal quality of the first capacity frequency point, the higher the communication quality and data transmission efficiency of the terminal at the first capacity frequency point; the lower the signal quality of the first capacity frequency point, the worse the communication quality and data transmission efficiency of the terminal at the first capacity frequency point.

[0107] For example, signal quality may include one or more of the following parameters: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), received signal strength indication (RSSI), signal to interference plus noise ratio (SINR), or signal to noise ratio (SNR).

[0108] For example, if event A is met at the first capacity frequency point, it indicates that the signal quality of the first capacity frequency point is relatively good. Optionally, if the terminal does not transmit data at the first capacity frequency point, the network device can configure the terminal to use the first capacity frequency point for data transmission, which is beneficial to improving the data transmission efficiency of the terminal.

[0109] For example, if event B is met at the first capacity frequency point, it indicates that the signal quality of the first capacity frequency point is poor. Optionally, if the terminal is transmitting data at the first capacity frequency point, the network device can configure the terminal to stop transmitting data at the first capacity frequency point. Further optionally, after configuring the terminal to stop transmitting data at the first capacity frequency point, the network device can reconfigure other capacity frequency points among the M capacity frequency points (excluding the first capacity frequency point) for data transmission, ensuring the data transmission efficiency of the terminal.

[0110] For example, when event C is met at the first capacity frequency point, it indicates that the signal quality of the first capacity frequency point is poor, while the signal quality of the second capacity frequency point is better. Optionally, the network device can be configured to switch the terminal from the first capacity frequency point to the second capacity frequency point for data transmission, thereby improving the data transmission efficiency of the terminal.

[0111] Optionally, the first threshold is greater than or equal to the second threshold, and / or the third threshold is less than or equal to the fourth threshold. Wherein, when the first threshold is greater than or equal to the second threshold, it can prevent the first capacity frequency point from simultaneously satisfying both event A and event B; when the third threshold is less than or equal to the fourth threshold, it can prevent the signal quality of the first capacity frequency point from being higher than the signal quality of the second capacity frequency point when event C is satisfied.

[0112] The above describes the first measurement event corresponding to the first capacity frequency point, using the first capacity frequency point as an example. The first measurement event corresponding to other capacity frequency points may be the same as or different from the first measurement event corresponding to the first capacity frequency point. This application does not limit this.

[0113] Optionally, among the M capacity frequency points, the threshold values ​​for the first measurement events corresponding to different capacity frequency points can be the same or different. For example, the M capacity frequency points may also include a second capacity frequency point, and the first measurement event corresponding to this second capacity frequency point includes event A', where event A' is that the signal quality of the second capacity frequency point is greater than a fifth threshold. This fifth threshold can be the same as or different from the first threshold. This approach allows for greater flexibility in the first measurement events corresponding to each capacity frequency point.

[0114] In some possible implementations, the M capacity frequency points are determined by the network device based on at least one parameter: Quality of Service (QoS), terminal capabilities, or data services. For example, the network device determines the M capacity frequency points from K capacity frequency points based on at least one of QoS, terminal capabilities, or data services. Here, the K capacity frequency points are the capacity frequency points managed by the network device, and K is an integer greater than or equal to M. In this way, each of the M capacity frequency points configured by the network device for the terminal satisfies or adapts to at least one of the terminal's QoS, terminal capabilities, or data services, which helps ensure the terminal's data transmission efficiency.

[0115] For example, a network device can group K capacity frequency points it manages based on at least one parameter, such as QoS, terminal capabilities, or data services, to obtain multiple capacity frequency point groups. When configuring capacity frequency point groups for a terminal, the network device can configure capacity frequency point groups for the terminal based on at least one parameter, such as QoS, terminal capabilities, or data services. For example, each of the M capacity frequency points may belong to the same capacity frequency point group within these multiple capacity frequency point groups.

[0116] Taking QoS as an example, QoS includes requirements for transmission bandwidth, transmission efficiency, transmission latency, or data packet loss rate. Network devices can group the K capacity frequency points according to QoS. For example, the resulting groups may include a first capacity frequency point group and a second capacity frequency point group, where the bandwidth of the frequencies included in the first capacity frequency point group is greater than the bandwidth of the frequencies included in the second capacity frequency point group. If the terminal has high QoS requirements, such as high data transmission efficiency requiring a larger data transmission bandwidth, the network device can configure the terminal with the first capacity frequency point group; if the terminal has low QoS requirements, such as low data transmission efficiency requiring less data transmission bandwidth, the network device can configure the terminal with the second capacity frequency point group.

[0117] Taking terminal capabilities as an example, terminals can be classified according to their capabilities. For instance, terminals can be divided into two categories: ordinary terminals and reduced-capability (RedCap) terminals or ambient IoT (A-IoT) terminals. RedCap terminals support less bandwidth, have lower processing power, and support fewer functions than ordinary terminals. A-IoT terminals communicate using backscattering; unlike ordinary terminals which can directly transmit signals, A-IoT terminals utilize the reflection characteristics of objects to transmit information via reflected signals. Network devices can group the K capacity frequency points based on terminal capabilities. For example, the resulting groups might include a first capacity frequency point group and a second capacity frequency point group, where the bandwidth of the frequencies in the first group is greater than the bandwidth of the frequencies in the second group, and / or the frequency of the frequencies in the first group is higher than the frequency of the frequencies in the second group. If the terminal requiring capacity frequency point configuration is a regular terminal, the network device can configure the first capacity frequency point group for this terminal because regular terminals support larger bandwidth and transmit larger amounts of data. If the terminal requiring capacity frequency point configuration is a RedCap terminal or an A-IoT terminal, the network device can configure the second capacity frequency point group for this terminal because RedCap terminals or A-IoT terminals support smaller bandwidth and transmit smaller amounts of data.

[0118] Taking data services as an example, different data services can have different priorities. Network devices can group the K capacity frequency points according to the data service. For example, the resulting groups may include a first capacity frequency point group and a second capacity frequency point group. The bandwidth of the frequency points included in the first capacity frequency point group is greater than the bandwidth of the frequency points included in the second capacity frequency point group, and / or, the frequency of the capacity frequency points included in the first capacity frequency point group is higher than the frequency of the frequency points included in the second capacity frequency point group. The data service associated with the first capacity frequency point group has a higher priority than the data service associated with the second capacity frequency point group. If the terminal's data service has a high priority and requires high data transmission efficiency, the network device can configure the terminal with the first capacity frequency point group; if the terminal's data service has a low priority and requires low data transmission efficiency, and does not require a large data transmission bandwidth, the network device can configure the terminal with the second capacity frequency point group.

[0119] The network device can also determine the M capacity frequency points based on other parameters, such as the network standard. The network standard may include time-division duplex (TDD) and frequency-division duplex (FDD), but this application embodiment does not limit this.

[0120] 203. When the first measurement event is met, the terminal sends first information, which indicates the capacity frequency point corresponding to the first measurement event.

[0121] Correspondingly, the network device receives the first information.

[0122] The terminal can determine whether a first measurement event corresponding to each of the M capacity frequency points is satisfied based on the signal quality of each of the M capacity frequency points. For example, if the M capacity frequency points include a first capacity frequency point and a second capacity frequency point, the terminal can determine whether the first capacity frequency point satisfies the first measurement event based on the signal quality of the first capacity frequency point, and determine whether the second capacity frequency point satisfies the first measurement event based on the signal quality of the second capacity frequency point. If the first capacity frequency point satisfies its corresponding first measurement event, the terminal sends first information indicating the first capacity frequency point. If the second capacity frequency point satisfies its corresponding first measurement event, the terminal sends first information indicating the second capacity frequency point.

[0123] In some possible implementations, the first information includes an identity (ID) of the capacity frequency point corresponding to the first measurement event. The identity of the capacity frequency point can be used to distinguish, mark, or locate the symbol or value of the capacity frequency point. Optionally, the identity can also be described as an index or number, which is not limited in this embodiment. Optionally, the identity of the capacity frequency point can be used to uniquely identify the capacity frequency point, or the identity of the capacity frequency point can be associated with a frequency range, indicating the frequency range in which the capacity frequency point is located. For example, the association between the identity of the capacity frequency point and the frequency range can be indicated by Table 1 below:

[0124] Table 1

[0125] When the capacity frequency point is identified as 1, it indicates that the capacity frequency point is located between 3000 and 3800 MHz. When the capacity frequency point is identified as 2, it indicates that the capacity frequency point is located between 3300 and 4200 MHz. When the capacity frequency point is identified as n, it indicates that the capacity frequency point is located between 1800 and 1820 MHz.

[0126] In some possible implementations, the M capacity frequency points include N capacity frequency points. The method further includes: when the terminal satisfies the first measurement event corresponding to each of the N capacity frequency points, it sends N first messages, and the network device receives the corresponding N first messages. The N first messages respectively indicate the N first capacity frequency points. Here, N is an integer greater than or equal to 1. The network device sends third information, and the terminal receives the corresponding third information. The third information indicates data transmission on one or more of the N capacity frequency points. Using this implementation, the terminal and the network device perform data transmission on the capacity frequency points indicated by the third information.

[0127] Optionally, the N capacity frequency points are the capacity frequency points among the M capacity frequency points whose signal quality is greater than a threshold value. Alternatively, the N capacity frequency points are the N capacity frequency points with the best signal quality among the M capacity frequency points. The N capacity frequency points with the best signal quality refer to the N capacity frequency points among the M capacity frequency points, where the signal quality of each of the N capacity frequency points is higher than that of the other capacity frequency points among the M capacity frequency points excluding the N capacity frequency points.

[0128] For example, as shown in Figure 3, assume that the M capacity frequency points include 5 capacity frequency points (capacity frequency point 1, capacity frequency point 2, capacity frequency point 3, capacity frequency point 4, and capacity frequency point 5). If the N capacity frequency points include the capacity frequency points among the M capacity frequency points whose signal quality is greater than a threshold, then according to Figure 3, the capacity frequency points greater than the threshold include capacity frequency points 2, 3, and 5. The N first messages sent by the terminal indicate capacity frequency points 2, 3, and 5, respectively. If the N capacity frequency points reported by the terminal are the N capacity frequency points with the best signal quality among the M capacity frequency points, and N equals 2, then the N first messages sent by the terminal indicate capacity frequency points 2 and 3, respectively.

[0129] In this way, network devices can determine the high-capacity frequency points with high signal quality based on the first information, and configure the terminals with high-capacity frequency points with high signal quality for data transmission, which helps to improve the data transmission efficiency of the terminals.

[0130] Optionally, when the third information indicates multiple capacity frequency points for data transmission, the terminal can employ carrier aggregation to transmit data based on the multiple capacity frequency points indicated by the third information. This approach helps improve data transmission efficiency.

[0131] In some examples, the third information can be carried on one or more of the following: WUS signal, chirp signal, downlink control information (DCI), or system message.

[0132] The following section introduces the WUS signal, chirp signal, DCI, and system messages:

[0133] The WUS signal is used to wake up the terminal. Optionally, when third information is carried on the WUS signal, the WUS signal can carry bit information, which is third information and can be used to indicate the identifier of the capacity frequency point. For example, the bit information can indicate the identifier of one or more capacity frequency points used for data transmission.

[0134] A chirp signal is a frequency-modulated signal whose frequency can change over time. For example, the frequency of a chirp signal can increase or decrease over time. Optionally, when third information is carried on a chirp signal, one or more of the waveform, slope, or starting frequency of the chirp signal are used to indicate one or more capacity frequency points for data transmission. Optionally, the terminal can detect the chirp signal at a time-frequency location pre-configured on the network device.

[0135] DCI can be used to schedule downlink data transmission or downlink data channels. Optionally, when third information is carried on the DCI, the terminal can obtain the bit information carried by the DCI through blind detection of the physical downlink control channel (PDCCH). This bit information is the third information and can be used to indicate the identifier of the capacity frequency point. For example, this bit information can indicate the identifier of one or more capacity frequency points used for data transmission. Further optionally, the DCI is a two-stage DCI, which includes a first-stage (stage 1) DCI and a second-stage (stage 2) DCI. The first-stage DCI carries information indicating the resource where the second-stage DCI is located, and the third information can be carried in either the first-stage DCI or the second-stage DCI.

[0136] System messages can be used to transmit system-level information, such as cell configuration information, system parameters, or system functions.

[0137] In some possible implementations, the first information also indicates the identifier of the camping frequency point accessed by the terminal. Optionally, the identifier of the camping frequency point can also be replaced by the identifier of the camping cell. Optionally, the capacity frequency point indicated by the first information can be associated with multiple camping frequencies, or there may be no pre-agreed association between the capacity frequency point and the camping frequency point. In this way, network devices can determine the location of the terminal through the camping frequency point, and when paging the terminal is required, paging can be performed without being conducted within the tracking area (TA) and radio access network notification area (RNA).

[0138] The following describes how to send the first message:

[0139] Method 1: The terminal can transmit first information on a capacity frequency point. For example, when in connected state, the terminal can transmit terminal capability information on a capacity frequency point. This terminal capability information indicates the capabilities supported by the terminal, and carries the first information. Alternatively, when triggering a cell reselection or neighbor cell selection measurement event, the terminal can transmit cell handover request information on a capacity frequency point. This cell handover request information requests a cell handover, and carries the first information.

[0140] Optionally, the capacity frequency point used to send the first information can be one or more of the M capacity frequency points configured for the network device.

[0141] Method 2: The terminal can send the first information on the camping frequency. For example, when the terminal is inactive, it can send uplink small data transmission (SDT) or minimized drive tests (MDT) on the camping frequency, and the SDT and MDT carry the first information.

[0142] Using the first information transmission method described above helps to reduce measurement reporting latency and air interface overhead.

[0143] In some possible implementations, the configuration information also indicates L camping frequency points and the second measurement events corresponding to each of the L camping frequency points, where L is an integer greater than or equal to 1. The method further includes: the terminal measuring the reference signal corresponding to each of the L camping frequency points to obtain the signal quality of each of the L camping frequency points; when the second measurement event is satisfied, the terminal sends second information, which indicates the corresponding camping frequency point for the second measurement event. With this implementation, when a camping frequency point satisfies the second measurement event, the terminal reports the capacity frequency point that satisfies the second measurement event to the network device via the second information. This allows the network device to determine the signal quality of the camping frequency point through the second information, which is beneficial for the network device to subsequently configure a capacity frequency point with better signal quality for the terminal, ensuring or improving the terminal's communication quality.

[0144] Optionally, there is an association between the L stationary frequency points and the M capacity frequency points. The relationship between the stationary frequency points and the capacity frequency points can be one-to-one, one-to-many, many-to-one, or many-to-many, and this application does not limit this. Further optionally, the association between the stationary frequency points and the capacity frequency points can be predefined by the protocol, configured by the network device, or agreed upon by the terminal and the network device through negotiation, and this application embodiment does not limit this.

[0145] The following section uses the identification of the stationary frequency point and the identification of the capacity frequency point as an example to introduce several possible correspondence methods.

[0146] Table 2 illustrates the one-to-one correspondence between stationary frequency points and capacity frequency points. Specifically, the stationary frequency point labeled x1 is associated with the capacity frequency point labeled y1, and the stationary frequency point labeled x2 is associated with the capacity frequency point labeled y2.

[0147] Table 2

[0148] Table 3 illustrates a one-to-many relationship between residing frequency points and capacity frequency points. The residing frequency point identified as x1 is associated with the frequency points identified as y1, y2, ... y2. nThe capacity frequency points of any one of them are interconnected.

[0149] Table 3

[0150] Table 4 illustrates the many-to-one relationship between residing frequency points and capacity frequency points. These are labeled x1, x2, ... x n Any of the stationary frequency points is correlated with the capacity frequency point identified as y1.

[0151] Table 4

[0152] Table 5 illustrates a many-to-many relationship between residing frequency points and capacity frequency points. These are labeled x1, x2, ... x n The dwell frequency of any one of them is identified as y1, y2, ... y n The capacity frequency points of any one of them are interconnected.

[0153] Table 5

[0154] The following example, using the first dwell frequency point as an example, illustrates the second measurement event corresponding to the first dwell frequency point. The first dwell frequency point is one of L dwell frequency points, and the second measurement event corresponding to the first dwell frequency point may include one or more of the following events:

[0155] Event D: The signal quality at the first dwell frequency point is greater than the sixth threshold; or,

[0156] Event E: The signal quality at the first dwell frequency is less than the seventh threshold; or,

[0157] Event F: The signal quality of the first stationary frequency is less than the eighth threshold, and the signal quality of the second stationary frequency is greater than the ninth threshold.

[0158] Among them, event D is the condition for the terminal to access the first camping frequency point, event E is the condition for the terminal to exit the first camping frequency point, and event F is the condition for the terminal to switch from the first camping frequency point to the second camping frequency point. The second camping frequency point is the other camping frequency points among the L camping frequency points besides the first camping frequency point.

[0159] For example, if event D is satisfied at the first dwell frequency, it indicates that the signal quality at the first dwell frequency is relatively good.

[0160] Optionally, if the terminal is not connected to the first camping frequency, the network device can configure the terminal to connect to the first camping frequency, which is beneficial to improving the communication quality of the terminal. Optionally, if the terminal device connects to the first camping frequency, and the terminal transmits data on the capacity frequency 1 associated with the first camping frequency, and the signal quality of the capacity frequency 1 associated with the first camping frequency is less than the sixth threshold, the second information also indicates that the signal quality of the capacity frequency 1 is good, but the signal quality of the capacity frequency associated with the first camping frequency is poor. The network device can configure the terminal to transmit data on other capacity frequencies associated with the first camping frequency besides capacity frequency 1, which is beneficial to improving the data transmission efficiency of the terminal.

[0161] For example, if event E is satisfied at the first dwell frequency, it indicates that the signal quality at the first dwell frequency is poor.

[0162] Optionally, if the terminal accesses the first camping frequency, the network device can configure the terminal to exit the first camping frequency. Further optional, after configuring the terminal to exit the first camping frequency, the network device can reconfigure the terminal to access other camping frequencies among the L camping frequencies besides the first camping frequency (e.g., camping frequency 2) to ensure terminal communication. Further optional, if the terminal does not switch to a capacity frequency after switching from camping frequency 1 to camping frequency 2, for example, if the terminal transmits data based on capacity frequency 1, the network device can reconfigure the first measurement event corresponding to capacity frequency 2 based on the cell parameters of camping frequency 2.

[0163] For example, when event F is met at the first stationary frequency, it indicates that the signal quality of the first stationary frequency is poor and the signal quality of the second stationary frequency is better. The network device can configure the terminal to switch from the first stationary frequency to the second stationary frequency for data transmission, thereby improving the efficiency of data transmission.

[0164] In some possible implementations, the first cycle is shorter than the second cycle, where the first cycle is the cycle for reporting the first information and the second cycle is the cycle for reporting the second information. By having the terminal actively and frequently report the first information to the network device, the network device can obtain the signal quality status of the capacity frequency point more promptly, thereby configuring an appropriate capacity frequency point for the terminal and ensuring the terminal's data transmission efficiency.

[0165] Optionally, the duration of the second cycle is A times the duration of the first cycle, where A is a positive integer. If the time when the terminal first reports the first information is the same as the time when it first reports the second information, the terminal can simultaneously report the first information and the second information during the i×A-1th first cycle, where i is a positive integer greater than or equal to 1.

[0166] For example, as shown in Figure 4, the duration of the second cycle is twice the duration of the first cycle. The time when the terminal first reports the first information is the same as the time when it first reports the second information. The terminal can report the first information and the second information simultaneously in the (2i-1)th first cycle, and report the first information only in the 2ith cycle.

[0167] Optionally, when the first cycle and the second cycle are unrelated, or when the reporting time of the first information and the reporting time of the second information do not overlap, the terminal may report the first information and the second information separately.

[0184] Optionally, the communication device 60 may further include one or more memories 630 for storing program instructions and / or data. The memory 630 is coupled to the processing circuit 620. The coupling in this embodiment is an indirect coupling or communication connection between communication devices, units, or modules, and can be electrical, mechanical, or other forms, used for information exchange between the communication devices, units, or modules. The processing circuit 620 may operate in conjunction with the memory 630. The processing circuit 620 may execute the program instructions stored in the memory 630. Optionally, at least one of the above-mentioned memories may be included in the processing circuit.

[0185] This application embodiment does not limit the specific connection medium between the transceiver circuit 610, processing circuit 620, and memory 630. In this application embodiment, the memory 630, processing circuit 620, and transceiver circuit 610 are connected via a bus 640 in Figure 6. The bus is represented by a thick line in Figure 6. The connection methods between other components are only for illustrative purposes and are not intended to be limiting. The bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, only one thick line is used in Figure 6, but this does not mean that there is only one bus or one type of bus.

[0186] In the embodiments of this application, the processing circuit may be a general-purpose processing circuit, a digital signal processing circuit, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc., and can implement or execute the various methods, steps, and logic block diagrams in the embodiments of this application.

[0187] In this application embodiment, the memory may include, but is not limited to, non-volatile memory such as hard disk drive (HDD) or solid-state drive (SSD), random access memory (RAM), erasable programmable read-only memory (EPROM), read-only memory (ROM), or compact disc read-only memory (CD-ROM), etc. Memory is any storage medium capable of carrying or storing program code in the form of instructions or data structures, and capable of being read and / or written by a computer (such as the communication device shown in this application), but is not limited to these.

[0189] When the communication device is powered on, the processing circuit 620 can read the software program in the memory 630, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processing circuit 620 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit.

When data is sent to the communication device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processing circuit 620. The processing circuit 620 converts the baseband signal back into data and processes the data.
