Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to communication methods and apparatus. Background Technology

[0002] With the rapid development of wireless communication technology, mobile terminal devices are becoming increasingly feature-rich, and users are placing higher demands on device performance and battery life. To meet these needs and reduce the power consumption of terminal devices, low-power wake-up signal (LP-WUS) technology can be employed. This technology wakes up the terminal device by monitoring LP-WUS through a low-power receiver when the device is in sleep mode, enabling communication and data transmission. To adapt to changes in the communication environment and ensure accurate wake-up, the terminal device can perform signal measurements through the low-power receiver and send communication quality-related information to the network device, allowing the network device to make service decisions. For example, if the terminal device moves within or outside the LP-WUS coverage area, the signal measurement results will change. The network device can determine the terminal device's location based on signal quality and activate or deactivate the low-power receiver's LP-WUS monitoring accordingly.

[0003] However, this method may result in high energy consumption for terminal devices and a high load on the network. Summary of the Invention

[0004] This application provides a communication method and apparatus, which are applied in the field of communication technology. They help network terminals make accurate business decisions and reduce the energy consumption of terminal devices and network load.

[0005] In a first aspect, embodiments of this application propose a communication method, the method comprising: acquiring first information and second information, the first information being used to indicate a first synchronization signal and a second synchronization signal, the second synchronization signal being a low-power synchronization signal, and the second information being used to indicate signal quality threshold information of the first synchronization signal; and sending third information based on the first synchronization signal and / or the second synchronization signal, and the signal quality threshold information of the first synchronization signal, the third information being used to indicate the signal quality of the first synchronization signal and / or the signal quality of the second synchronization signal.

[0006] In one possible implementation, the method is executed by a terminal device or a chip within the terminal device.

[0007] The communication method provided in this application allows a terminal device to measure the first and second synchronization signals indicated by the first information to obtain the corresponding signal quality. The terminal device then sends third information based on the signal quality and the signal quality threshold information of the first synchronization signal indicated by the second information. The terminal device can determine whether to send the third information and the specific information included in the third information. For example, the terminal device can determine to send the third information when a certain relationship exists between the signal quality of the first synchronization signal and its signal quality threshold information, such as the signal quality being greater than or less than the signal quality threshold. If this relationship is not met, the third information is not sent. The terminal device can also send different information based on different relationships between the signal quality of the first synchronization signal and its signal quality threshold information. For example, it can send the signal quality of both the first and second synchronization signals when the signal quality is greater than the signal quality threshold, and send the first synchronization signal but not the second synchronization signal when the signal quality is less than the signal quality threshold. This allows the terminal device to accurately decide whether to send the third information, enabling on-demand transmission of the third information, reducing the terminal device's energy consumption and lowering the network load.

[0008] In conjunction with the first aspect, in one possible implementation of the first aspect, the first information is specifically used to indicate either: the frequency of the first synchronization signal and the frequency of the second synchronization signal; or, the frequency of the first synchronization signal and the offset between the frequency of the second synchronization signal and the frequency of the first synchronization signal.

[0009] In this implementation, the terminal device can obtain the frequency points corresponding to the first synchronization signal and the second synchronization signal. By obtaining the corresponding frequency points, the object of signal measurement is identified. The terminal device can concentrate resources and time on these corresponding frequency points for measurement, thereby improving measurement efficiency and reducing unnecessary measurement overhead.

[0010] In conjunction with the first aspect, in one possible implementation of the first aspect, the second information is also used to indicate the signal quality threshold information of the second synchronization signal.

[0011] In this implementation, the terminal device can obtain the threshold information of the first synchronization signal and the second synchronization signal. Thus, the terminal device can use the first synchronization signal, the second synchronization signal, and their threshold information to determine whether to send the third information or to determine the information included in the third information. Correspondingly, the network device can obtain more comprehensive information, which helps to make more effective business decisions.

[0012] In conjunction with the first aspect, in one possible implementation of the first aspect, the second information is specifically used to indicate a first threshold and a second threshold, the first threshold being used to indicate the threshold corresponding to the signal quality of the first synchronization signal, and the second threshold being used to indicate the threshold corresponding to the signal quality of the second synchronization signal.

[0013] In this implementation, different synchronization signals can use different thresholds. Configuring these thresholds allows the terminal device to trigger the transmission of third-party information only when the signal quality reaches a certain value. Different thresholds can define different quality of service requirements. This helps reduce unnecessary information transmission, lowers the energy consumption of terminal devices, reduces network signaling load, and improves network efficiency.

[0014] In conjunction with the first aspect, in one possible implementation of the first aspect, the terminal device sends third information based on the first information and the second information, including: sending the third information when the first condition or the second condition is met; the first condition includes: the signal quality of the first synchronization signal is greater than a first threshold, and the signal quality of the second synchronization signal is greater than a second threshold; and / or, the second condition includes: the signal quality of the first synchronization signal is less than or equal to the first threshold, or the signal quality of the second synchronization signal is less than or equal to the second threshold.

[0015] In this implementation, the terminal device obtains the relationship between the signal quality and threshold of the synchronization signal, determines the conditions for sending the third information, and enables the terminal device to send the third information as needed according to the conditions. This helps to reduce the energy and resource consumption caused by the terminal device sending the third information, such as signaling overhead and signaling load in the network, and improves network efficiency.

[0016] In conjunction with the first aspect, in one possible implementation of the first aspect, the second information is further used to indicate that if the signal quality of the first synchronization signal is greater than the first threshold, to trigger the measurement of the signal quality of the second synchronization signal or to determine whether the signal quality of the second synchronization signal is greater than the second threshold.

[0017] In this implementation, the measurement or judgment of the second synchronization signal is based on whether the signal quality of the first synchronization signal is greater than the first threshold. If the signal quality of the first synchronization signal does not reach the first threshold, the measurement or judgment operation of the second synchronization signal will not be performed, which helps the terminal device reduce operations and can further reduce the energy consumption of the terminal device.

[0018] In conjunction with the first aspect, in one possible implementation of the first aspect, both the first threshold and the second threshold correspond to the reference signal received power.

[0019] In this implementation, the first and second thresholds are the RSRP thresholds. RSRP can directly reflect the signal strength and determine whether the communication quality between the terminal device and the network device meets the quality requirements.

[0020] In conjunction with the first aspect, in one possible implementation of the first aspect, the second information is used to indicate a third threshold and the first indication information. The third threshold indicates the threshold corresponding to the signal quality of the first synchronization signal. The first indication information indicates that the third information includes the signal quality of the second synchronization signal. Sending the third information according to the first and second information includes: sending the signal quality of the first synchronization signal and the signal quality of the second synchronization signal when either the first or second condition is met. The first condition includes: the signal quality of the first synchronization signal is greater than the third threshold; and / or, the second condition includes: the signal quality of the first synchronization signal is less than or equal to the third threshold.

[0021] In this implementation, the terminal device can determine whether the conditions for sending the third information are met based on the signal quality and threshold of the first synchronization signal. Furthermore, if the conditions for sending the third information are met, the terminal device determines the signal quality of the second synchronization signal that needs to be sent in the third information based on the first indication information. The terminal device can avoid judging the signal quality of the second synchronization signal, simplifying its processing logic and enabling it to send the third information more promptly. Correspondingly, the network device can acquire the third information in a timely manner.

[0022] In conjunction with the first aspect, in one possible implementation of the first aspect, the third information is specifically used to indicate at least one of the following: a reference signal received power value, a reference signal received quality value, or second indication information, the second indication information being used to indicate that the monitoring of activating or deactivating a low-power wake-up signal is satisfied.

[0023] In this implementation, the terminal device can send a numerical value indicating signal quality, using specific values ​​to indicate communication quality. For example, the reference signal received power value can directly reflect signal strength, or the reference signal received quality value can reflect the overall communication quality, including signal strength and interference. The terminal device can also send a second indication, indicating whether the communication quality required for executing a specific service is met. For instance, the second indication could indicate that the communication quality between the terminal device and the network meets the conditions required for activating or deactivating the low-power wake-up signal. The terminal device can also simultaneously send both the numerical signal quality value and the indication of whether the required communication quality is met. The terminal device can transmit communication quality-related information in various forms, selecting the appropriate data transmission method based on network conditions and device capabilities to optimize transmission efficiency.

[0024] In conjunction with the first aspect, in one possible implementation of the first aspect, the third information includes a measurement report indicating: a first reference signal received power value of the first synchronization signal, and / or a second reference signal received power value of the second synchronization signal.

[0025] In this implementation, the terminal device can send third information in the form of a measurement report, which includes the RSRP of either the first synchronization signal or the second synchronization signal, or both. The network device can then obtain the signal strength information, determine the communication quality between the terminal device and the network device, and thus aid in business decision-making.

[0026] In conjunction with the first aspect, in one possible implementation of the first aspect, the measurement report is used to indicate: the reception quality value of the first reference signal of the first synchronization signal, and / or the reception quality value of the second reference signal of the second synchronization signal.

[0027] In this implementation, the signal quality included in the measurement report can also be RSRQ. Through RSRQ, the network device can obtain the signal quality of the first synchronization signal and / or the second synchronization signal measured by the terminal device, taking into account the ratio of signal to noise and interference, providing the network device with more comprehensive information about communication quality, which helps to make more accurate business decisions.

[0028] In conjunction with the first aspect, in one possible implementation of the first aspect, the measurement report includes a first measurement report and a second measurement report, wherein the first measurement report carries a first reference signal received power value and / or a first reference signal received quality value for a first synchronization signal, and the second measurement report carries a second reference signal received power value and / or a second reference signal received quality value for a second synchronization signal.

[0029] In this implementation, the signal quality of the first synchronization signal and the signal quality of the second synchronization signal can be sent through different measurement reports, which can reduce the data volume of a single measurement report, reduce the limitation on bandwidth resources, and help improve transmission efficiency.

[0030] In conjunction with the first aspect, in one possible implementation of the first aspect, the method further includes: the terminal device receiving third indication information, the third indication information being used to indicate the activation or deactivation of the monitoring of the low-power wake-up signal, the third indication information being determined based on the third information.

[0031] In this implementation, the network device can determine whether to activate or deactivate the monitoring of the low-power wake-up signal of the terminal device based on third-party information. The terminal device then activates or deactivates the signal according to the instructions, allowing the terminal device to be activated or deactivated on demand, thus meeting the data transmission requirements while reducing energy consumption.

[0032] Secondly, embodiments of this application propose a communication method. The method includes: sending first information and second information, wherein the first information indicates a first synchronization signal and a second synchronization signal, the second synchronization signal being a low-power synchronization signal, and the second information indicating signal quality threshold information of the first synchronization signal; and receiving third information, wherein the third information is sent by a terminal device based on the first synchronization signal and / or the second synchronization signal and the signal quality threshold information of the first synchronization signal, and the third information indicating the signal quality of the first synchronization signal and / or the signal quality of the second synchronization signal.

[0033] In one possible implementation, the method is performed by a network device or a chip within the network device.

[0034] Through the communication method provided in this application embodiment, the network device can instruct the terminal device to send signal quality threshold information as needed. Accordingly, the network device can obtain the communication quality between itself and the terminal device as needed, which helps the network device to make accurate business decisions, such as activating or deactivating the monitoring of low-power wake-up signals, reducing unnecessary information measurement and information transmission, and reducing the energy consumption of the terminal device and the network load.

[0035] In conjunction with the second aspect, in one possible implementation of the second aspect, the first information is specifically used to indicate either: the frequency of the first synchronization signal and the frequency of the second synchronization signal; or, the frequency of the first synchronization signal and the offset between the frequency of the second synchronization signal and the frequency of the first synchronization signal.

[0036] In conjunction with the second aspect, in one possible implementation of the second aspect, the second information is also used to indicate the signal quality threshold information of the second synchronization signal.

[0037] In conjunction with the second aspect, in one possible implementation of the second aspect, the second information is specifically used to indicate a first threshold and a second threshold, the first threshold being used to indicate the threshold corresponding to the signal quality of the first synchronization signal, and the second threshold being used to indicate the threshold corresponding to the signal quality of the second synchronization signal.

[0038] In conjunction with the second aspect, in one possible implementation of the second aspect, the third information is sent by the terminal device based on conditions determined by the first information and the second information, the conditions including: a first condition indicating that the signal quality of the first synchronization signal is greater than a first threshold and the signal quality of the second synchronization signal is greater than a second threshold; and / or a second condition indicating that the signal quality of the first synchronization signal is less than or equal to the first threshold, or the signal quality of the second synchronization signal is less than or equal to the second threshold.

[0039] In conjunction with the second aspect, in one possible implementation of the second aspect, the second information is also used to indicate that if the signal quality of the first synchronization signal is greater than a first threshold, the signal quality of the second synchronization signal is triggered for measurement.

[0040] In conjunction with the second aspect, in one possible implementation of the second aspect, both the first threshold and the second threshold correspond to the reference signal received power.

[0041] In conjunction with the second aspect, in one possible implementation of the second aspect, the second information is used to indicate a third threshold and a first indication information. The third threshold indicates the threshold corresponding to the signal quality of the first synchronization signal. The first indication information indicates that the third information includes the signal quality of the second synchronization signal. The third information is sent by the terminal device based on conditions determined by the first and second information. The conditions include: a first condition indicating that the signal quality of the first synchronization signal is greater than or equal to the third threshold; and / or a second condition indicating that the signal quality of the first synchronization signal is less than or equal to the third threshold.

[0042] In conjunction with the second aspect, in one possible implementation of the second aspect, the third information is specifically used to indicate at least one of the following: a reference signal received power value, a reference signal received quality value, or second indication information, the second indication information being used to indicate that the monitoring of activating or deactivating a low-power wake-up signal is satisfied.

[0043] In conjunction with the second aspect, in one possible implementation of the second aspect, the third information includes a measurement report indicating: the first reference signal received power value of the first synchronization signal, and / or the second reference signal received power value of the second synchronization signal.

[0044] In conjunction with the second aspect, in one possible implementation of the second aspect, the measurement report is used to indicate: the reception quality value of the first reference signal of the first synchronization signal, and / or the reception quality value of the second reference signal of the second synchronization signal.

[0045] In conjunction with the second aspect, in one possible implementation of the second aspect, the measurement report includes a first measurement report and a second measurement report, wherein the first measurement report carries a first reference signal received power value and / or a first reference signal received quality value for a first synchronization signal, and the second measurement report carries a second reference signal received power value and / or a second reference signal received quality value for a second synchronization signal.

[0069] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0070] 1. Discontinuous reception (DRX)

[0071] Discontinuous Reception (DRX), also known as intermittent reception, is an energy-saving technology used in wireless communication networks, such as when terminal devices communicate with base stations. This method allows the terminal to periodically enter sleep mode or wake-up mode. In sleep mode, it does not monitor the Physical Downlink Control Channel (PDCCH) subframes, while in wake-up mode, it does monitor the PDCCH subframes, thus saving energy consumption of the terminal device.

[0072] The DRX mechanism of a terminal device in connected mode can be called connected DRX (CDRX). The DRX cycle consists of an active period (also known as wake-up time) and a sleep period (also known as sleep time). During the active period, the terminal device periodically wakes up to monitor network signals and check for downlink data or signaling that needs to be received. During the sleep period, the device enters a low-power state and does not monitor network signals. The sleep state or sleep period can also be referred to as sleep mode, such as sleep state or sleep period.

[0073] For example, Figure 1 The diagram illustrates a possible DRX cycle and its active and sleep periods. The active period, represented by "On Duration," occurs when the terminal device is awake and can monitor PDCCH subframes, using control information on the PDCCH to determine if data needs to be received. The sleep period, represented by "Opportunity for DRX," occurs when the terminal device enters a low-power mode, does not monitor PDCCH subframes, and reduces battery consumption.

[0074] The DRX cycle can be configured as a long cycle and / or a short cycle. A short cycle allows for a fast response to network requests, while a long cycle is used in steady-state conditions to maximize energy efficiency.

[0075] 2. Wake-up signal and low-power wake-up signal (LP-WUS)

[0076] A wake-up signal is used to wake up the terminal device, enabling it to receive downlink data packets in a timely manner. For example, the wake-up signal can be a PDCCH subframe, carrying downlink control information (DCI). The DCI contains control information, such as data transmission on specific time and frequency resources, indicating that the terminal device has data to receive. During its active period, the terminal device monitors the DCI to wake itself up and initiate data transmission.

[0077] Low-power wake-up signals are wake-up signals designed for small terminal devices that are power-sensitive, static, have limited mobility, or move at low speeds. When used with a low-power receiver, they can reduce the energy consumption of the terminal device.

[0078] 3. Main receiver (MR) and low-power wake-up receiver (LR or LP-WUR)

[0079] MR corresponds to the main radio frequency interface of the terminal device. It is mainly used to interact and communicate with network devices, obtain downlink data sent by the core network device through the network device, receive complex messages sent by other network devices, and send data and other messages to the network device. Therefore, MR usually has relatively high power consumption.

[0080] LR (Low Power Receiver) is a receiver with lower power consumption compared to MR (Mixed Receiver). It is also known as a low-power receiver or wake-up receiver. Because LR is only used to receive relatively simple signals, such as LP-WUS (which may only be sequence-correlated and do not require PDCCH decoding), the signals received by LR are simpler than those of MR, and the signal processing complexity is lower. Therefore, LR consumes less power than MR.

[0081] 4. Synchronization signal (SS) and low-power synchronization signal (LP-SS)

[0082] SS (Synchronization Signal) can include a primary synchronization signal (PSS) and / or a secondary synchronization signal (SSS). The PSS can be used for time synchronization and partial cell identification, while the SSS can be used for complete cell identification and frame synchronization. The physical layer identifier of a cell can be determined based on the SSS and PSS. SS can be part of a synchronization signal block (SSB) for initial access, beam management, and system information acquisition. For example, SS can be used for time-frequency synchronization by the primary receiver, or for radio resource management (RRM) measurements.

[0083] LP-SS can be used for time-frequency synchronization in low-power receivers, as well as for radio resource management (RRM) measurements. For example, LP-SS can be transmitted periodically. Specifically, LP-SS includes at least one specific synchronization sequence, which the low-power receiver can use to perform time / frequency offset correction.

[0084] 5. Signal quality

[0085] Signal quality reflects the performance of a wireless communication system, including the impact of signal transmission on signal integrity at the receiver. Signal quality can be represented by parameters such as reference signal received power (RSRP) and reference signal received quality (RSRQ).

[0086] RSRP refers to the average power of a reference signal received on a specific frequency resource (such as a frequency point), providing a metric for signal strength. For example, RSRP is the linear average power of a reference signal on a resource element (RE) within a cell. RSRP can be expressed in decibel-milliwatts (dBm). RSRP can be obtained by sampling and averaging the power of the reference signal, which can be an SSB, a channel state information reference signal (CSI-RS), or a cell-specific reference signal (CRS), etc.

[0087] RSRQ is calculated by measuring RSRP and Received Signal Strength Indicator (RSSI). The relationship between RSRQ and RSRP is as follows: RSRQ = N × RSRP / RSSI, where N is the number of resource blocks used to measure RSSI, and RSSI is the total received power within the channel bandwidth, including noise and interference. Terminal equipment can sample the received signal to obtain the values ​​of RSRP and RSSI, and then calculate the RSRQ value using these values.

[0088] In some cases, better signal quality corresponds to higher RSRP or RSRQ values, while poorer signal quality or stronger interference results in lower RSRP or RSRQ values.

[0089] 6. Other terms

[0090] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with substantially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0091] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0092] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes 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, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, and c can be single or multiple.

[0093] In this application's embodiments, "enabling" and "activating" have different meanings. "Enabling" refers to providing the necessary conditions or permissions for a function or feature, making it possible for it to operate. It can be viewed as turning on a function, allowing it to be invoked or used when needed. Enabling involves configuration, setting, or authorization processes, but does not mean that the function is already running or executing. For example, in a software system, enabling a module may involve modifying a configuration file or granting permissions, allowing the module to be invoked when needed. "Activating," on the other hand, means starting or executing a function or process. Activation is a step following enabling, indicating that the function has begun to run and function. Activation involves the actual operation or execution process. For example, in a network device, activating a port means that the port has begun transmitting data.

[0094] The technical solutions of this application embodiment can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G system or new radio (NR) system, and future evolution communication systems, such as 6th generation (6G) system, etc.

[0095] The terminal equipment in this application embodiment can also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.

[0096] The access network equipment and core network equipment in this application embodiment can be collectively referred to as network equipment.

[0097] The core network equipment in this application embodiment can be core network equipment in a fourth-generation (4G) system, such as a mobile management entity (MME) or a serving gateway (SGW), or it can be core network equipment in a 5G system, such as an access and mobility management function (AMF) network element or a user plane function (UPF) network element, or it can be core network equipment with other names. This application embodiment does not limit this.

[0098] Access network equipment can be any device with wireless transceiver capabilities. Access network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WiFi) system. It can also be a 5G base station (next-generation Node B, gNB) in a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0099] In some deployments, a gNB may include a centralized unit (CU) and a dedicated unit (DU). A gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU can handle non-real-time protocols and services, such as implementing the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and / or the packet data convergence protocol (PDCP) layer. The DU can handle physical layer protocols and real-time services, such as implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. A DU can connect to only one CU or to multiple CUs, while a CU can connect to multiple DUs. Communication between CUs and DUs can be achieved via the F1 interface. The AAU can implement some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since the information from the RRC layer is ultimately delivered to the PHY layer and thus becomes PHY layer information, or is transformed from PHY layer information, in this architecture, higher-level signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU.

[0100] It is understood that access network equipment can be one or more of the following: CU nodes, DU nodes, and AAU nodes. Furthermore, a CU can be classified as an access network device in the radio access network (RAN) or as an access network device in the core network (CN); this application does not impose any limitations on this classification.

[0101] Access network equipment provides services to cells. Terminal devices communicate with cells through transmission resources (e.g., frequency domain resources, or spectrum resources) allocated by the access network equipment. The cell can belong to a macro base station (e.g., macro eNB or macro gNB) or to a base station corresponding to a small cell. Small cells can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0102] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 2 The communication system applicable to the embodiments of this application will be described in detail.

[0103] Figure 2 A schematic diagram of a communication system 200 applying an embodiment of this application is shown. The communication system 200 includes an access network, a core network, and an Internet Protocol (IP) Multimedia Subsystem (IMS) or the Internet.

[0104] The access network includes at least one terminal device, such as Figure 2 The terminal device 201 shown also includes at least one access network device, such as... Figure 2 The access network devices 202 and 203 are shown. The core network devices can connect to the access network devices wirelessly or via wired means, and terminal devices within the coverage area of ​​the access network devices can connect to them wirelessly.

[0105] like Figure 2 As shown, access network device 202 may include cell A and cell B, and access network device 203 may provide services to cell C. Terminal device 201 is located within the range of cell A, and the terminal device currently serves cell A and can interact with cell A. Cells B and C are neighboring cells of cell A.

[0106] Access network devices 202 and 203 can communicate with terminal device 201 via a wireless link. Terminal device 201, access network device 202, or access network device 203 can be configured with multiple antennas, which may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Additionally, terminal device 201, access network device 202, or access network device 203 also includes a transmitter chain and a receiver chain, which, as will be understood by those skilled in the art, may include multiple components related to signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, or antennas). Therefore, access network devices 202 and 203 can communicate with terminal device 201 via multi-antenna technology.

[0107] The core network's main functions are to provide user connections, manage users, and carry services, serving as the bearer network and providing an interface to external networks. User connection establishment includes functions such as mobility management (MM), call management, switching / routing, and call recording notifications (which, in conjunction with intelligent network services, establish connections to peripheral intelligent network devices).

[0108] The core network of a 5G network is called 5G Core (or 5GC for short). 5GC will use general-purpose network function virtualization devices to replace the dedicated communication devices of 4G networks.

[0109] It should be noted that, Figure 2 The core network in the network architecture shown can be obtained by merging 4G and 5GC. That is, the core network in this network architecture can include network elements from both 4G and 5GC. For example, the core network in this network architecture can include access and mobility management function (AMF) network elements, mobility management entity (MME) network elements, serving gate way (SGW) network elements, packet data network gate way (PGW) network elements, session management function (SMF) network elements, user plane function (UPF) network elements, unified data management (UDM) network elements, and home subscriber server (HSS) network elements, etc.

[0110] In some embodiments of this application, the core network in this network architecture may include converged network elements derived from 4G network elements and 5GC network elements. Examples include SMF+PGW-C, UPF+PGW-U, UDM+HSS, etc. Here, PGW-C is the control plane node of the PGW network element, and PGW-U is the user plane node of the PGW network element.

[0111] In some embodiments of this application, Figure 2The core network in the illustrated network architecture may include a proxy session border control (PSBC) network element, which is a combined network element integrating session border control (SBC), proxy call session control function (P-CSCF), access transfer control function (ATCF), and access transfer gateway (ATGW). As an SBC network element, it connects the IMS core network / softswitch network with the external user access area, enabling service access for IMS / softswitch users, facilitating interoperability of user services in different network environments, ensuring IMS / softswitch network security, and supporting functions such as QoS management, CAC traffic control, media management, and CDR media call detail records.

[0112] Each network element in the core network can also be called a functional entity. It can be a network element implemented on dedicated hardware, a software instance running on dedicated hardware, or an instance of virtualized function on an appropriate platform.

[0113] It should be understood that the names of all network elements in the embodiments of this application are merely examples. In future communications, such as 6G, the names of all network elements in the embodiments of this application may be other names, or the network elements involved in this application may be replaced by other entities or devices with the same function, etc., and this application does not limit them in this regard. This is a unified explanation here and will not be repeated later. Optionally, the various network elements in the embodiments of this application may be communication devices, or chips or chip systems that can be used in the communication devices, etc., and this application does not limit them in this regard.

[0114] Understandable Figure 2 The core network in the network architecture shown may also include other devices, network elements, network entities, or network subsystems, such as policy control function (PCF) network elements, which are not limited in this application. It should be noted that this application does not limit the distribution of each network element in the core network; the specific distribution method can be found in relevant technical documents, which will not be elaborated here.

[0115] IMS is a network architecture that provides voice and multimedia communication services (such as voice, video, and text messaging) based on the Internet Protocol (IP) network. The Internet, also known as the international network, refers to a vast network of interconnected networks linked by a set of common protocols, forming a logically single, enormous international network.

[0116] It should be understood that Figure 2 This is just an illustration; the communication system 200 may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 2 The number of core network devices, access network devices, and terminal devices included in the communication system 200 is not shown in the diagram. This application embodiment does not limit the number of such devices in the communication system 200.

[0117] Optionally, the communication system 200 may also include other network entities such as a network controller and a mobility management entity, but the embodiments of this application are not limited thereto.

[0118] It should be understood that Figure 2 The communication system 200 shown is merely an example. This application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices contained in each communication system.

[0119] In communication systems, DRX technology can be used to enable terminals to be periodically woken up and transmit data during active periods, thereby reducing the energy consumption of terminal devices.

[0120] To wake up a terminal device, one possible implementation is that the network can send a wake-up signal. The terminal device monitors this signal to determine if there is a data transmission requirement and then wakes up. For example, the terminal device can monitor PDCCH subframes to determine if data transmission is needed, thus deciding whether to wake up. PDCCH subframe monitoring can be performed by the terminal device's main receiver, but the main receiver consumes a lot of energy because it also handles other functions besides the wake-up signal.

[0121] In another possible approach, the network can send a low-power wake-up signal. The terminal device can receive and process this low-power wake-up signal through a separate receiver. This receiver, compared to the main receiver, has simpler functionality and processing logic, and can use less energy for signal reception and processing; therefore, it can also be called a low-power receiver or a low-power wake-up receiver. For example, such as... Figure 3 The terminal equipment includes two receivers, MR and LR.

[0122] The terminal device includes a main receiver and a low-power receiver. In one implementation of DRX, if the terminal device is in a connected state and within the wake-up signal coverage area (e.g., Figure 4 In region 1), the network can enable terminal devices to monitor LP-WUS via RRC signaling. Terminal devices monitor LP-WUS through LR, such as receiving and processing LP-WUS. MR can be disabled while LR monitoring is enabled; this state can be called ultra-deep sleep mode. If the terminal device is outside the wake-up signal coverage area (e.g., ...), ... Figure 4 If region 2 is not part of region 1, then LP-WUS will not be monitored by LR.

[0123] When LR determines that the terminal device needs to be woken up, for example when the terminal device detects that the LP-WUS contains the packet information of the terminal device, the terminal device enables MR to perform signal monitoring and processing, such as the terminal device monitoring PDCCH.

[0124] LP-WUS configuration parameters can include period and offset. The period indicates how often LP-WUS is monitored. The offset indicates the interval between the current LP-WUS and the nearest DRX active period.

[0125] In some cases, both DRX and LP-WUS signals coexist in the network. When a terminal device needs to transmit data, it can monitor the PDCCH during the active period of the DRX corresponding to that LP-WUS signal by monitoring the LP-WUS signal. For example, Figure 5 The LP-WUS is monitored at a period of 2 milliseconds (ms), and the monitoring times of LP-WUS are numbered sequentially as LP-WUS0, LP-WUS1, and so on. The DRX period is 26ms. If LP-WUS2 detects a data transmission requirement, the PDCCH is monitored during the active period 1 of DRX period 1 at a certain interval, such as 6ms. For example, if LP-WUS28 detects a data transmission requirement, the PDCCH is monitored during the active period 3 of DRX period 3.

[0126] If no data transmission demand is detected in LP-WUS, the adjacent DRX will not be effective, and even if the DRX enters an active period, the PDCCH will not be monitored. For example, Figure 5 The LP-WUS15 in the middle did not detect data transmission demand, and PDCCH monitoring was not performed during the active period 2 of DRX cycle 2.

[0127] Another possible implementation is that the terminal device can determine whether to monitor the PDCCH based solely on the low-power wake-up signal. For example... Figure 6 If LP-WUS2, LP-WUS5, and LP-WUS16 detect a data transmission request, they will perform PDCCH monitoring after a certain interval. If other LP-WUS systems do not detect a data transmission request, they will not perform PDCCH monitoring for a period of time until the next LP-WUS system detects a data transmission request.

[0128] The aforementioned PDCCH monitoring can be performed by the LR (Local Range Controller) detecting a data transmission request via LP-WUS, then enabling MR (Local Range Controller), and monitoring the PDCCH through MR. The information obtained from monitoring the PDCCH is then used to wake up the terminal device. Alternatively, the LP-WUS detection of a data transmission request can occur when the terminal device detects that the LP-WUS signal contains its own packet information, indicating that the network device will send data to the terminal device.

[0129] The above-described method for monitoring low-power wake-up signals can be applied to the reception of non-periodic data streams. This monitoring method can be used when the data stream is non-periodic and requires low latency.

[0130] In the above methods, the network device cannot obtain the communication quality between the terminal device (especially the LR) and the network device, and cannot make an accurate decision on whether to perform LP-WUS monitoring. The terminal device (the LR) continuously monitors LP-WUS according to the configured parameters (period, offset, etc.). Even when the terminal device has no data transmission needs, or when the terminal device is outside the coverage area of ​​the low-power wake-up signal, the terminal device will still consume resources and energy to monitor LP-WUS. This results in high energy consumption for the terminal device, especially the low-power receiver, and also high energy consumption for the entire communication system.

[0131] Similar situations may arise in other service scenarios related to LP-WUS or LR, where network devices are unable to obtain information about the communication quality between the terminal device, especially the low-power receiver, and the network device, thus hindering service decisions. One possible solution is for the terminal device to send information about the communication quality between the low-power receiver and the network device, such as the signal quality of the synchronization signal, to the network device.

[0132] Terminal devices can measure SS and LP-SS to determine the communication quality between the terminal and the network. For example, Figure 4Area 1, as shown, represents the coverage area of ​​the Low Power Wake-up Signal (LP-SS). Within Area 1, terminal devices can receive the LP-SS, and the Low Power Synchronization Signal (LP-SS) also exists in this area. Area 2 represents the cell coverage area, which is larger than that of Area 1. Within Area 2, terminal devices can receive signals or data sent by the base station, and the Synchronization Signal (SS) also exists in this area.

[0133] The signal quality of SS and / or LP-SS measured by the terminal device can indicate the communication quality between the terminal and the network, thereby helping the network make service decisions. For example, if the terminal device is in Area 1, the signal quality measured by the terminal device for SS and LP-SS is at a high level. If the terminal device is in Area 2 but outside Area 1, the signal quality measured by the terminal device for SS meets the requirements for network communication, but the signal quality measured for LP-SS may be at a low level, indicating that the terminal device cannot correctly receive LP-WUS.

[0134] However, low-power receivers are limited by factors such as battery capacity. Frequent signal measurements and information transmission to terminal devices result in high energy consumption, and the large amount of information transmission also puts a heavy load on the network.

[0135] In view of this, embodiments of this application provide a communication method. This method allows a terminal device to acquire first information and second information. The first information may indicate multiple synchronization signals that the terminal device needs to measure, such as a first synchronization signal and a second synchronization signal, wherein the second synchronization signal is a low-power synchronization signal. The second information indicates signal quality threshold information related to the first synchronization signal. The terminal device can send third information to a network device based on the first synchronization signal and / or the second synchronization signal indicated by the first information, and the signal quality threshold information of the first synchronization signal. The third information may indicate the signal quality of the first synchronization signal and / or the signal quality of the second synchronization signal.

[0136] The communication method provided in this application embodiment allows the terminal device to determine the target of signal measurement based on the first synchronization signal and the second synchronization signal indicated by the first information. This helps the terminal device to concentrate energy and resources on measuring specific targets and reduce unnecessary energy consumption.

[0137] The terminal device can also determine the conditions for sending third information based on the signal quality threshold of the first synchronization signal indicated by the second information. This signal quality threshold information reflects the communication quality requirements between the terminal device and the network. Therefore, the terminal device can determine whether to send third information based on the signal quality measured by the first synchronization signal and / or the second synchronization signal, and the signal quality threshold information of the first synchronization signal. The terminal device only sends third information when the corresponding conditions are met; otherwise, it does not send third information. This reduces the frequency of third information transmission by the terminal device, lowering its energy consumption and reducing network load.

[0138] Furthermore, in addition to sending the third information, the terminal device can also send different information based on different relationships between the signal quality of the first synchronization signal and its signal quality threshold. For example, if the signal quality of the first synchronization signal is less than its signal quality threshold, the first synchronization signal is sent, but the signal quality of the second synchronization signal is not sent. Thus, the network device can determine the communication quality with the terminal device based on the signal quality of the first synchronization signal. Alternatively, if the signal quality of the first synchronization signal is greater than its signal quality threshold, the signal quality of both the first and second synchronization signals is sent, allowing the network device to obtain more comprehensive communication quality information from the terminal device, which helps the network device make business decisions.

[0139] Therefore, through the communication method provided in this application embodiment, the terminal device can report communication quality-related information on demand, reduce the energy consumption and network load of the terminal device, and help the network make business decisions.

[0140] For example, the third information may include indication information for activating or deactivating the monitoring of the low-power wake-up signal. The network device can determine whether to activate or deactivate the terminal device's monitoring of LP-WUS by combining the indication information from the terminal device. The third information may also include a signal quality value, which reflects the current data transmission needs of the terminal device or whether it is within the coverage area of ​​the low-power wake-up signal. Thus, the network device can control whether to activate the terminal device's monitoring of LP-WUS. Therefore, in situations where monitoring is not suitable (such as not being within the coverage area of ​​LP-WUS), the low-power receiver will not perform monitoring, thereby helping to reduce the energy consumption of the low-power receiver and the terminal device.

[0141] The following will combine Figures 7 to 10 The communication methods of the embodiments of this application will be described in detail.

[0142] Figure 7 The interaction between network devices and terminal devices is described in detail, including steps S701 to S704.

[0143] S701. The network device sends first information and / or second information to the terminal device. The first information is used to indicate a first synchronization signal and a second synchronization signal. The second synchronization signal is a low-power synchronization signal. The second information is used to indicate the signal quality threshold information of the first synchronization signal.

[0144] Accordingly, the terminal device receives first information and / or second information from the network device.

[0145] In this embodiment of the application, the first synchronization signal indicated by the first information may be SS, including a primary synchronization signal and / or a secondary synchronization signal, and the second synchronization signal may be LP-SS.

[0146] Synchronization signals are transmitted via a carrier wave and correspond to a frequency value or frequency range, which can be called a frequency point. The first synchronization signal corresponds to the first frequency point, also known as the SS frequency point. The second synchronization signal corresponds to the second frequency point, also known as the LP-SS frequency point. The first information can be the first frequency point and the second frequency point, respectively indicating the first synchronization signal and the second synchronization signal.

[0147] For example, a frequency point can be indicated by a frequency point value, such as a frequency value of 700MHz, 3.5GHz, etc. The frequency point value can also be indicated by a frequency band number, such as n78 (3.3GHz to 3.8GHz) or n41 (2.496GHz to 2.690GHz). The frequency point value is also represented by an absolute radio frequency channel number (ARFCN). The ARFCN is an integer value that uniquely identifies a channel on a specific frequency. Accordingly, the first information can be the SS and LP-SS frequency point values, the frequency band number, or the absolute radio frequency channel number. For example, if the SS frequency point is 3.5GHz and the LP-SS frequency point is 2.5GHz, the first information could be (3.5GHz, 2.5GHz), or (n78, n41), or represented by the ARFCN as (516000, 499220).

[0148] The first information can also be the frequency value of one of multiple frequency points, as well as the offset between that frequency point and other frequency points. For example, if the SS frequency point is 3.5GHz and the LP-SS frequency point is 2.5GHz, the first information can be indicated by the SS frequency point and the offset between the LP-SS frequency point and the SS frequency point, such as (3.5GHz, 400MHz) or (n78, -37), or represented by ARFCN as (516000, -16780).

[0149] When explaining the content related to the first and second synchronization signals, the first and second frequency points can be used for indication. For example, the measurement result of the first frequency point can represent the measurement result of the first synchronization signal, and the measurement result of the second frequency point can represent the measurement result of the second synchronization signal, etc. The first and second frequency points can also be replaced with other information used to indicate the first and second synchronization signals.

[0150] In this way, the terminal device can obtain the frequency points corresponding to the first synchronization signal and the second synchronization signal. By obtaining the corresponding frequency points, the object of signal measurement can be identified. The terminal device can concentrate resources and time on these corresponding frequency points for measurement, thereby improving measurement efficiency and reducing unnecessary measurement overhead.

[0151] The first information can also be indicated through one or more measurement objects (or measObjects). For example, when a measurement object may include a first frequency point and a second frequency point, the first information can be configured through a measurement object.

[0152] for example Figure 8 This illustrates a relationship between report-related information, which may include information such as the measurement object, measurement identifier, and report configuration identifier. Figure 8 The measurement object `measObject 0` includes a first frequency point (SS frequency point) and a second frequency point (LP-SS frequency point). Alternatively, when a measurement object includes one frequency point, the first information can be configured through multiple measurement objects, such as... Figure 8 The first measurement object measObject 1 includes a first frequency point, and the second measurement object measObject 2 includes a second frequency point.

[0153] In some cases, the object being measured can also be associated with a measurement identifier, and correspondingly, primary information can be indicated through one or more measurement identifiers. For example... Figure 8 In the code, measObject 0 is associated with measid0, and measid0 can be used to indicate the first and second frequency points. measObject 1 is associated with measid1, and measid1 can be used to indicate the first frequency point. measObject 2 is associated with measid3, and measid3 can be used to indicate the second frequency point.

[0154] In this way, the terminal device can indicate the first synchronization signal and the second synchronization signal through one or more measurement objects, and can establish a correspondence between the measurement object and the synchronization signal or the frequency point of the synchronization signal. This allows the first synchronization signal and the second synchronization signal to be indicated with less information, thereby reducing the amount of data transmission in the network and reducing the network load.

[0155] In this embodiment of the application, the signal quality threshold information of the first synchronization signal indicated by the second information can be the first threshold of the first frequency point.

[0156] In some cases, the second information can also indicate the signal quality threshold information of the second synchronization signal, such as the second threshold corresponding to the second frequency point.

[0157] In this way, the terminal device can obtain signal quality threshold information from multiple synchronization signals, providing more comprehensive information and helping it to more accurately determine whether to send third information. Furthermore, setting different thresholds for different synchronization signals allows the terminal device to trigger the transmission of third information only when the signal quality reaches a certain value; different thresholds can define different quality of service requirements. This helps reduce unnecessary information transmission, lowers the terminal device's energy consumption, reduces network signaling load, and improves network efficiency.

[0158] Since signal quality can be indicated by different parameters, such as RSRP and / or RSRQ, in some cases, this second information can also indicate a specific signal quality parameter. For example, if the signal quality parameter is RSRP, then the first threshold and the second threshold are the thresholds corresponding to RSRP.

[0159] In one possible scenario, even without carrying the signal quality parameter, the terminal device and network device can determine the signal quality parameter corresponding to the signal quality threshold in the second information by pre-configuring the same rules.

[0160] In this way, the terminal device can compare the signal strength with the corresponding threshold value based on the relationship between the first synchronization signal and the first threshold, and / or the second synchronization signal and the second threshold, and determine whether the communication quality between the terminal device and the network device meets the quality requirements through the signal strength indicated by RSRP.

[0161] Network devices can send first and second information to terminal devices via signaling or system information.

[0162] For example, network devices send first and / or second information via signaling messages. Signaling messages may include radio resource control (RRC) signaling, non-access stratum (NAS) signaling, session management and resource allocation signaling, application layer signaling, etc. RRC signaling may further include UE-specific (dedicated) RRC signaling and common RRC signaling. For instance, the first and / or second information may be carried in signaling messages such as RRC Connection Request, RRC Connection Setup, and RRC Reconfiguration. Signaling messages may also be MAC signaling, carrying various control information in MAC layer data units to support the management and control of radio resources, including one or more of the following: power control commands, control requests, buffer status reports, priority indications, discontinuous reception (DRX) commands, and fast repeat indications. Signaling messages may also be physical layer signaling, which can be various contents sent in the physical channel, including one or more of the following: synchronization signals, cell-specific reference signals (CRS), demodulation reference signals (DMRS), link control information such as resource control and transmission format indication, channel state information reference signals (CSI-RS), DCI, random access information, etc.

[0163] For example, network devices send first and / or second information through system information. System information may include a master information block (MIB) and a system information block (SIB). The MIB can provide system bandwidth, system frame number (SFN), physical HARQ indicator channel (PHICH) configuration information, etc. The SIB includes one or more of SIB1, SIB2, SIB3, or SIB1i, where i is a positive integer identifying different system information blocks. SIB1 may contain cell access-related information, such as cell identifier, public land mobile network identifier, access control information, time information, etc. SIB2 can provide parameters required for RRC connection establishment, such as random access channel configuration, uplink power control parameters, scheduling information, etc. SIB3 may contain cell reselection parameters to help the terminal select a suitable cell when moving.

[0164] The first and second information can be sent using the same or different signaling or system information. Information in the first information indicating the first and second synchronization signals can also be sent using the same or different signaling or system information. If the second information includes signal quality threshold information indicating the first and second synchronization signals, this threshold information can be sent using the same or different signaling or system information. For example, the information for the first and second synchronization signals can be sent via an RRC Connection Request, or the information for the first synchronization signal can be sent via an RRC Connection Request, and the information for the second synchronization signal can be sent via an SIB.

[0165] One possible implementation is that the network device sends first and second information through report configuration information. For example, the network device and the terminal device define a first event, and the report configuration information triggered by the event carries event-related information, such as the event identifier and the corresponding threshold for triggering the measurement report.

[0166] For example, the report configuration information indicates the first event via Ax, which can be called the event identifier. Ax is associated with a threshold for the first event, including a threshold for a first frequency point and a threshold for a second frequency point. This threshold can be a threshold for different signal quality parameters, and the report configuration information can indicate the signal quality parameters corresponding to the activated threshold, such as RSRP and / or RSRQ.

[0167] For example, the report configuration information indicates a second event via Ay, which can be referred to as an event identifier. Ay is associated with a threshold for the second event, including a threshold for the first frequency point and / or a threshold for the second frequency point. The report configuration information may indicate the signal quality parameters corresponding to the deactivation threshold, which may be a threshold for RSRP and / or RSRQ.

[0168] Report configuration information can also be indicated through report config id, which can be associated with one or more measurement config ids. For example, if report config 0 is associated with measure0, the measurement results (results) of the first and second frequency points in measureObject 0 associated with measure0 can be sent to the network device through the same report. Alternatively, if report config 1 is associated with measure1 (associated with measureObject 1, corresponding to the first frequency point) and measure3 (associated with measureObject 2, corresponding to the second frequency point), the terminal device can send the measurement results of the first and second frequency points to the network device through the same report. Or, if report config 1 is associated with measure1 (associated with measureObject 1, corresponding to the first frequency point) and report config 3 is associated with measure3 (associated with measureObject 2, corresponding to the second frequency point), the terminal device can send the measurement results of the first and second frequency points to the network device through two separate reports.

[0169] In this way, an association is established between the report identifier, the measurement identifier, and the measurement object. The measurement object defines the frequency points that need to be measured, and the report configuration information indicated by the report identifier indicates the corresponding thresholds. Thus, the network device can use the report identifier and its corresponding report configuration information to indicate the first and second information to the terminal device. The first and second information reflect the network device's requirement for reporting measurement reports, enabling the terminal device to send measurement reports as needed.

[0170] In some cases, the second information, while indicating the first and second thresholds, can also indicate that if the measurement results at the first frequency point meet specific conditions, it will trigger a determination at the second frequency point as to whether the conditions for sending the third information are met.

[0171] In some cases, the second information is used only to indicate the threshold corresponding to the signal quality of the first synchronization signal, and can be referred to as the third threshold. The second information may also include first indication information, which can indicate whether the signal quality of the second synchronization signal is included in the third information.

[0172] For example, the report configuration information configures event A1 or A2. The A1 event and A2 event information include a third threshold of the first synchronization signal and first indication information. The first indication information indicates that the third information includes the signal quality of the second synchronization signal. Then, when the A1 event occurs, the signal quality of the first synchronization signal and / or the second synchronization signal can be sent.

[0173] In this way, the terminal device can determine whether the conditions for sending the third information are met based on the signal quality and threshold of the first synchronization signal. Furthermore, if the conditions for sending the third information are met, the terminal device can determine, based on the first indication information, whether the signal quality of the second synchronization signal needs to be sent in the third information. The terminal device can avoid judging the signal quality of the second synchronization signal, simplifying its processing logic and time, and helping it to send the third information more promptly. Correspondingly, the network device can acquire the third information in a timely manner.

[0174] In some cases, the threshold used in the first condition may be different from the threshold used in the second condition. For example, the threshold in the first condition corresponding to the first synchronization signal may be greater than the threshold in the second condition corresponding to the first synchronization signal. Or, the threshold in the first condition corresponding to the second synchronization signal may be greater than the threshold in the second condition corresponding to the second synchronization signal.

[0175] S702. The terminal device determines whether to send the third information based on the first synchronization signal and / or the second synchronization signal, and the signal quality threshold information of the first synchronization signal.

[0176] The terminal device can obtain the signal quality of the first synchronization signal based on the first synchronization signal indicated by the first information, and / or obtain the signal quality of the second synchronization signal by measuring the second synchronization signal indicated by the first information.

[0177] The terminal device can obtain the corresponding conditions based on the first and second information, and report the third information when the conditions are met.

[0178] For example, the first condition can be that both condition one and condition two are satisfied simultaneously:

[0179] Condition 1: The signal quality of the first synchronization signal is greater than or equal to the first threshold.

[0180] Condition 2: The signal quality of the second synchronization signal is greater than or equal to the second threshold.

[0181] The second condition can be that condition three and / or condition four are satisfied:

[0182] Condition 3: The signal quality of the first synchronization signal is less than or equal to the first threshold.

[0183] Condition 4: The signal quality of the first synchronization signal is less than or equal to the second threshold.

[0184] In some cases, all or part of the above conditions may not include the case where the signal quality of the synchronization signal is equal to the corresponding threshold.

[0185] In some cases, the first condition can be used to activate the low-power wake-up signal monitoring function of the terminal device, and can be called the activation condition. The second condition can be used to deactivate the low-power wake-up signal monitoring function of the terminal device, and can be called the deactivation condition.

[0186] The terminal device can measure the signal quality of the first synchronization signal and the second synchronization signal indicated by the first information. For example, if the signal quality parameter is RSRP, the RSRP measurement result obtained by measuring the first synchronization signal at the first frequency point (SS frequency point) is ssResult-rsrp, and the threshold of RSRP corresponding to the SS frequency point in the second information is x1; the RSRP measurement result obtained by measuring the second synchronization signal at the second frequency point (LP-SS frequency point) is lpssResult-rsrp, and the threshold of RSRP corresponding to the LP-SS frequency point in the second information is y1.

[0187] Therefore, the first condition can be satisfying the following relationship:

[0188] Condition 1: ssResult-rsrp>=x1, and,

[0189] Condition 2: lpssResult-rsrp>=y1.

[0190] The second condition can be that the following relationship is satisfied:

[0191] Condition 3: ssResult-rsrp<=x1, and / or,

[0192] Condition 4: lpssResult-rsrp<=y1.

[0193] After obtaining the measurement results, the terminal device can determine whether the first or second condition is met based on the first and second information, and then determine whether to send the third information.

[0194] The measurement results described above can also be the measurement results of other signal quality parameters, such as the measurement results of RSRQ, ssResult-rsrq, lpssResult-rsrq, etc. In the embodiments of this application, ssResult and lpssResult can also be used to indicate the signal quality of the first synchronization signal and the second synchronization signal, respectively.

[0195] In this way, the terminal device can clearly define the conditions for sending the third information through the first and second information, and can determine whether the current signal quality meets the corresponding conditions based on the measurement results. The third information is sent only when the conditions are met, and not when the conditions are not met. This can reduce the resource overhead (such as signaling overhead) caused by the system sending the third information.

[0196] In one possible approach, when the terminal determines whether the first condition is met, it can first determine whether condition one is met, and if condition one is met, then proceed to determine condition two.

[0197] For example, event Ax1 corresponds to condition one, and event Ax2 corresponds to condition two. When the corresponding conditions are met, it can be said that the corresponding event has occurred. The report configuration information is configured with the following rule: if Ax1 occurs, determine whether Ax2 has occurred. Alternatively, the network device and terminal device can be pre-configured with the following rule: if Ax1 occurs, determine whether Ax2 has occurred; if Ax1 has not occurred, do not determine whether Ax2 has occurred; or, if condition one is met, perform the condition two check; if condition one is not met, do not check whether condition two is met.

[0198] In this way, if condition one is not met, the terminal device can skip the judgment of condition two, reducing the computational overhead of the terminal device and further saving the energy consumption of the terminal device.

[0199] In another possible approach, when the second information only includes the third threshold of the first synchronization signal, for example, if the third threshold of event A1 or A2 is x2, then the first condition can be satisfying the following relationship: ssResult-rsrp>=x2, and the second condition can be satisfying the following relationship: ssResult-rsrp<=x2.

[0200] If the second information also includes the first indication information, the terminal device needs to determine the signal quality of whether or not to send the second synchronization signal based on the first indication information, provided that the first or second condition is met.

[0201] In this way, the terminal device can determine the third information to be sent based solely on the first synchronization signal, which can further reduce the judgment and processing operations of the terminal device, reduce the processing complexity of the terminal device, and save the energy consumption of the terminal device.

[0202] S703. The terminal device sends third information to the network device, the third information being used to indicate the signal quality of the first synchronization signal and / or the signal quality of the second synchronization signal.

[0203] When the first condition is met or the second condition is met, the terminal device sends the third information to the network device.

[0204] For example, the measurement result obtained at the first frequency point (SS frequency point) is ssResult, which, along with the corresponding threshold x1, satisfies condition one: ssResult >= x1; and the measurement result at the second frequency point (LP-SS frequency point) is lpssResult, which, along with the corresponding threshold y1, satisfies condition two: lpssResult >= y1. The terminal device can determine that the first condition is met and can send third information to the network device. This third information can be used in some cases to determine the activation of the low-power wake-up signal monitoring.

[0205] For example, the measurement result obtained at the first frequency point (SS frequency point) is ssResult, which, along with the corresponding threshold x1, satisfies condition three: ssResult <= x1; or, the measurement result at the second frequency point (LP-SS frequency point) is lpssResult, which, along with the corresponding threshold y1, satisfies condition four: lpssResult <= y1. The terminal device can determine that the second condition is met and can send the third information to the network device. This third information can be used in some cases to determine the monitoring for deactivating the low-power wake-up signal.

[0206] The third information can be the signal quality of the first synchronization signal and the second synchronization signal. For example, when the first condition is met, the third information includes ssResult and lpssResult.

[0207] The third information can also be either the signal quality of the first synchronization signal or the signal quality of the second synchronization signal. For example, when condition three of the second condition is met, the third information includes ssResult. When condition four of the second condition is met, the third information includes lpssResult. In some cases, when the first condition is met, the third information may not include ssResult, but may include lpssResult.

[0208] The third piece of information can also be an indication of whether the first or second condition is met. For example, a value of 0 indicates that the first condition is met, a value of 1 indicates that the second condition is met, and a null value indicates that neither condition is met. In practice, other indication methods can also be used, such as using other numerical values, characters, or fields to indicate whether the first or second condition is met, such as true or false. Alternatively, the indication information can also be event identifiers or measurement identifiers in the measurement report.

[0209] Terminal devices can send third information to network devices via measurement reports or user auxiliary information (UAI). If the third information includes the signal quality of the first synchronization signal (ssResult) and the signal quality of the second synchronization signal (lpssResult), ssResult and lpssResult can be sent to the network device via the same measurement report or UAI, or via different measurement reports or UAI.

[0210] In some cases, after receiving third information, the network device can send second indication information to the terminal device based on the third information. This indication information is used to instruct the terminal device to perform monitoring of the low-power wake-up signal or not to perform monitoring. It can also be called activation indication information or deactivation indication information.

[0211] Accordingly, after receiving the second instruction information, the terminal device performs monitoring to activate or deactivate the low-power wake-up signal according to the second instruction information. For example, performing monitoring to activate the low-power wake-up signal may include starting LR and turning off MR, and monitoring LP-WUS according to the configuration parameters of LP-WUS; deactivating monitoring to deactivate the low-power wake-up signal may include stopping LR monitoring of LP-WUS.

[0212] Using the method described in this step, the terminal device sends third information to the network device based on quality-related information. This information can be sent when the signal quality meets certain conditions, which reduces the signaling overhead of the terminal device sending third information to the network device.

[0213] The foregoing has provided a detailed description of the interaction between the terminal device and the network device involved in the embodiments of this application. Through the method in the embodiments of this application, the terminal device can obtain first information and second information from the network device, determine the corresponding frequency point and signal quality threshold information, and determine whether to send third information to the network device based on the first and second information. This allows the network device to determine whether to activate or deactivate the low-power wake-up signal monitoring function of the terminal device based on the third information. This approach helps the network device accurately determine whether to activate or deactivate the terminal device's low-power wake-up signal monitoring. By executing or stopping the low-power wake-up signal monitoring when the signal quality reaches certain conditions, the network device can reduce unnecessary monitoring of low-power signals, thus helping to reduce the energy consumption of the terminal device.

[0214] In this embodiment, step S701 is optional. The terminal device may also obtain the first information and / or the second information through information pre-configured in the terminal device. The terminal device may pre-configure the first information and the second information, or it may pre-configure some of the information and obtain the other part of the information through the network device.

[0215] One possible implementation is that the terminal device can pre-configure first information (e.g., SS frequency point and / or LP-SS frequency point). This first information indicates the synchronization signal information for signal measurement after the terminal device enables the low-power wake-up signal monitoring function. For example, if the terminal device pre-configures the SS frequency point and LP-SS frequency point, then after the terminal's low-power wake-up signal monitoring function is enabled, the synchronization signals of the SS frequency point and LP-SS frequency point can be measured to obtain the corresponding RSRP and / or RSRQ measurement results. This first information can also be pre-configured in the network device, enabling the network device to determine whether the measurement result is a measurement result of the first synchronization signal and / or the second synchronization signal after obtaining the corresponding measurement result.

[0216] In another possible implementation, the terminal device can pre-configure second information (e.g., multiple thresholds). For example, if the terminal device pre-configures the RSRP threshold of the first synchronization signal, then after enabling the low-power wake-up signal monitoring function, the terminal device measures the RSRP and compares it with the RSRP threshold to determine whether to send third information to the network device.

[0217] By adopting the above pre-configuration method, the overhead caused by signaling interaction between terminal devices and network devices can be reduced.

[0218] In this embodiment, the entity executing one or more of the actions involved in the above steps can be the LR in the terminal device, such as receiving the first and second information, obtaining the measurement results of the signal quality, determining whether the first or second condition is met, and determining the information contained in the third information. During the LR operation, the MR in the terminal device can still be in a dormant state. In this way, only the low-power receiver of the terminal device works, while the high-power receiver does not work, which can reduce the energy consumption of the terminal device.

[0219] Figure 9 This is an implementation method for reporting third-party information through measurement reports. Specifically, it includes steps S901 to S905, which will be described in detail below.

[0220] S901, The terminal device sends user capability information (low-power receiver type) to the network device. Accordingly, the network device receives the user capability information from the terminal device.

[0221] User capability information can indicate the functions and features supported by a terminal device, such as user type, user signal processing capabilities, hardware configuration information, device type, etc., and is sometimes referred to as UE capability information.

[0222] For example, terminal devices such as Figure 3 As shown, this includes low-power receivers, and the user capability information may include the low-power receiver type (LR type). The LR type can be the signal modulation method supported by the LR, such as on-off keying (OOK) modulation technology and / or orthogonal frequency division multiplexing (OFDM) modulation technology.

[0223] OOK is a simple and commonly used modulation technique. It is a special form of binary amplitude shift keying (ASK). In OOK modulation, signal transmission is represented by two states: on and off. Specifically, the "on" state represents a binary "1". In this state, the signal is transmitted. The "off" state represents a binary "0". In this state, the signal is not transmitted. The advantage of this modulation method is its simplicity of implementation, making it particularly suitable for low-power and low-complexity communication systems.

[0224] OFDM is a multi-carrier modulation technique. The basic principle of OFDM is to divide a high-speed data stream into multiple lower-speed sub-data streams, which are then transmitted simultaneously via multiple mutually orthogonal subcarriers. Each subcarrier is mutually orthogonal in the frequency domain, meaning that under ideal conditions, they will not interfere with each other. This orthogonality allows the subcarriers to be closely aligned in the spectrum, thereby improving spectral efficiency.

[0225] In some cases, the LR supports multiple modulation techniques, such as OOK and OFDM, allowing different modulation methods to be selected for modulation and demodulation of the low-power wake-up signal in different scenarios. Alternatively, in some cases, the LR only supports OOK or OFDM, in which case the low-power signal can be modulated and demodulated using either OOK or OFDM modulation.

[0226] Terminal devices can send user capability information to network devices during initialization, registration, and other processes. For example, terminal devices can carry user capability information in RRC signaling messages, such as UE Capability Information Messages, Attach Requests, Tracking Area Update (TAU) Requests, Registration Requests, or Initial UE Messages. Terminal devices may also send user capability information to network devices after receiving a UE Capability Information Request from the base station.

[0227] S902, Monitoring of low-power wake-up signals for network devices enabling terminal devices.

[0228] Monitoring the enabling of low-power wake-up signals may include an enable indication and / or configuration parameters from the network device to the terminal device. Accordingly, the terminal device receives the enable indication and / or configuration parameters from the network device.

[0229] The enable indicator is used to indicate that the terminal device is allowed to perform the action of monitoring low-power wake-up signals, and can be a function switch or permission management information, etc.

[0230] The configuration parameters for the low-power wake-up signal indicate the period and offset of the low-power wake-up signal, etc. For details, please refer to [link / reference needed]. Figure 5 and Figure 6 The detailed explanations of the configuration parameters in the relevant content will not be repeated here.

[0231] After receiving the enable instruction and / or configuration parameters, the terminal device can reserve corresponding resources, such as computing resources, storage resources and timing resources, for the low-power wake-up signal, in order to prepare for the monitoring of the low-power wake-up signal.

[0232] Network devices can enable the low-power wake-up signal monitoring function of terminal devices through signaling messages or system information. For example, they can send enable instructions and / or configuration parameters through user configuration / reconfiguration messages. After receiving the corresponding information, the terminal device completes resource configuration. After completing resource configuration, the terminal device can enable LR.

[0233] After completing resource configuration, the terminal device can send an enable response message to the network device. This message, along with the message sent from the network device to the terminal device, forms a message pair. This response message indicates to the network device whether the low-power wake-up signal monitoring function of the terminal device was successfully or unsuccessfully enabled.

[0234] This step can be sent by the network device when it determines that the terminal device has low-power wake-up signal monitoring capability based on user capability information. For example, this step is executed when the terminal device has a low-power wake-up signal receiver; it is not executed if the terminal device does not have a low-power wake-up signal receiver. This step may also be determined by the network device based on network information (such as hardware capabilities, protocol type, load, etc.). For example, this step is not executed if the network does not support the user type carried in step S901.

[0235] S903. The network device sends the measurement object (SS frequency point, LP-SS frequency point) and report configuration information (Ax and Ay event information) to the terminal device. Correspondingly, the terminal device receives the measurement object and report configuration information from the network device.

[0236] The measured object can serve as the first piece of information, and may include information about the SS frequency point and the LP-SS frequency point, respectively indicating the first synchronization signal and the second synchronization signal. For example, the SS frequency point and the LP-SS frequency point can be used to indicate the first synchronization signal and the second synchronization signal. Exemplarily, the measured object is indicated in the following manner:

[0237] measObject x: measObjectNR(ssFreq,lpssFreq(smtc)).

[0238] Where x is the identifier of the measurement object (measObject), which can be an integer or a letter. measObject x is associated with the SS frequency information ssFreq and the LP-SS frequency information lpssFreq. Specifically, the frequency can be... Figure 7 The detailed descriptions of the embodiments shown are not repeated here.

[0239] For example, measObject 0: measObjectNR(3.5GHz, 2.5GHz) can indicate that ssFreq is 3.5GHz and lpssFreq is 2.5GHz.

[0240] If a measurement object only indicates the information of one synchronization signal, then the first synchronization signal and the second synchronization signal can be indicated by different measurement objects, for example:

[0241] measObject 1: measObjectNR (3.5GHz), measObject 2: measObjectNR (2.5GHz).

[0242] The measurement object may also include measurement time window configuration information, which indicates in which time windows the terminal device should measure the frequency point. For example, the SSB measurement time configuration (synchronization signal block measurement timing configuration, SMTC) indicates the time window for signal measurement. In the above expression, SMTC can be used to indicate the time window for SS and / or LP-SS measurements.

[0243] The report configuration information can serve as secondary information, indicating the signal quality threshold information for the first synchronization signal and / or the second synchronization signal. The report configuration information can be indicated via a report configuration identifier.

[0244] For example, the report configuration information for report configuration identifier reportConfig 0 is shown in Table 1.

[0245] Table 1

[0246]

[0247] Here, `triggerType` being `event` indicates that the measurement report is triggered by an event. The event Id that triggers the measurement report is `Ax`. The event information of event `Ax` can be used to indicate the conditions that trigger the report to be sent, and can correspond to... Figure 7 The first condition in the embodiment. In some cases, this first condition can also be used as a condition for activating low-power wake-up signal monitoring. The Ax event can be used to activate the low-power wake-up signal monitoring function of the terminal device, and can also be called the low-power wake-up signal first event or the first event.

[0248] The information corresponding to the Ax event includes the thresholds for SS and LP-SS, namely Ax-ssThreshold and Ax-lpssThreshold, respectively. Specifically, the threshold can be the value of RSRP or RSRQ. For example, in Table 1, the threshold value is the value of RSRP, and threshold-RSRP are -90dBm and -100dBm, respectively. Correspondingly, the first condition can be that both condition one and condition two are satisfied simultaneously, including:

[0249] Condition 1: ssResult >= Ax - ssThreshold, and,

[0250] Condition 2: lpssResult >= Ax - lpssThreshold.

[0251] Where ssResult represents the measurement result on the SS frequency point, and lpssResult represents the measurement result on the LP-SS frequency point. When both conditions one and two are met, an Ax event occurs, triggering the transmission of the measurement report.

[0252] Similarly, another event that triggers a measurement report has an eventId of Ay. The event information of event Ay can be used to indicate another condition that triggers the sending of the report, and can correspond to... Figure 7 The second condition in the embodiment. In some cases, this second condition can also be used as a condition to deactivate low-power wake-up signal monitoring. The Ax event can be used to deactivate the low-power wake-up signal monitoring function of the terminal device, and can also be called the low-power wake-up signal first event or the first event.

[0253] The information corresponding to the Ay event includes the thresholds for SS and LP-SS, namely Ay-ssThreshold and / or Ay-lpssThreshold. Specifically, the threshold can be the value of RSRP or RSRQ. For example, if the threshold value is the value of RSRP, then threshold-RSRP are -90dBm and -100dBm, respectively. Correspondingly, the second condition can be satisfying at least one of conditions three or four, including:

[0254] Condition 3: SSB measurement result <= Ay-ssThreshold, and / or,

[0255] Condition 4: LP-WUS measurement result <= Ay-lpssThreshold.

[0256] If either condition three or condition four is met, the Ay event occurs, triggering the report to be sent.

[0257] The report configuration information can also include other parameters, such as the signal quality parameter that triggers the report (triggerQuantity) and the signal quality parameter corresponding to the measurement results in the report (reportQuantity), which can be RSRP or RSRQ, etc. reportQuantity can be the same as or different from triggerQuantity. For example, in Table 1, the information for reportQuantity is set to sameAsTriggerQuantity, indicating that reportQuantity uses the same signal quality parameter as triggerQuantity. Alternatively, if triggerQuantity is RSRP, reportQuantity can be specified as either RSRP or RSRQ.

[0258] Other parameters include the number of reports sent (reportAmount), which can be set to an integer or an unlimited number (infinity). For example, three times means the terminal device can send a maximum of three reports to the network device after the conditions corresponding to the event are met. The report sending interval (reportInterval) indicates the time interval between two reports sent by the terminal device, such as 100ms.

[0259] In some cases, the thresholds for Ax and Ay events can be issued in different report configuration files, each corresponding to a different report configuration identifier. For example, the Ax event might correspond to reportConfig 1, and the Ay event to reportConfig 2. Alternatively, the thresholds for Ax and Ay events can be issued in the same report configuration file, corresponding to the same report configuration identifier, as shown in Table 2, where both Ax and Ay events correspond to reportConfig 0.

[0260] Table 2

[0261]

[0262]

[0263] The report configuration information indicated by reportConfig 0 includes information related to the Ax and Ay events, where the Ax event corresponds to event identifier 1 and threshold 1, and the Ay event corresponds to event identifier 2 and threshold 2.

[0264] The above report configuration information needs to be associated with a specific measurement object in order to determine whether the measurement results of the specific measurement object meet the conditions corresponding to a specific event.

[0265] In one possible implementation, the correspondence between the measurement identifier, the measurement object identifier, and the report configuration identifier can be configured through measurement configuration information. Table 3 shows one possible measurement configuration information, where measId 0, measObject 0, and report config 0 can have a one-to-one relationship.

[0266] Table 3

[0267] Information Item Information item identifier Information value Measurement Marking measId 0 Measurement object identification measObjectId 0 Report configuration identifier report config Id 0

[0268] Tables 4 and 5 show another possible measurement configuration information. MeasId 1 and MeasId 2 are associated one-to-one with MeasObject 1 and MeasObject 2, respectively. Both MeasId 1 and MeasId 2 are associated with ReportConfig Id 3, representing a many-to-one relationship. For example, the report configuration information shown in Table 2 corresponds to ReportConfig Id 3, and the SS frequency point and LP-SS frequency point correspond to MeasObject 1 and MeasObject 2, respectively. Therefore, the two measurement objects can be associated with the same report configuration identifier using the methods shown in Tables 4 and 5.

[0269] Table 4

[0270] Information Item Information item identifier Information value Measurement Marking measId 1 Measurement object identification measObjectId 1 Report configuration identifier report config Id 3

[0271] Table 5

[0272] Information Item Information item identifier Information value Measurement Marking measId 2 Measurement object identification measObjectId 2 Report configuration identifier report config Id 3

[0273] In addition to the above-mentioned one report configuration identifier corresponding to one or more measurement identifiers, one measurement identifier can also correspond to multiple report configuration identifiers. For example, as shown in Table 1, report configuration identifier 1 is the report configuration identifier corresponding to the Ax event, and report configuration 2 is the report configuration identifier corresponding to the Ay event. The measurement object measObject 1 is the LP-SS frequency point. This measurement object can be associated with report configuration 1 and report configuration 2. The measurement results of the LP-SS frequency point are used for conditional judgment of Ax and Ay events, respectively.

[0274] S904. The terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report from the terminal device.

[0275] When the terminal device meets the conditions corresponding to the event in the measurement configuration information, it sends the corresponding measurement results to the network device through a measurement report.

[0276] For example, the report configuration information is shown in Table 1, the indicated event is Ax, the measured signal quality parameter is RSRP, the measurement result on the SS frequency point is ssResult = -85dBm, and the measurement result on the LP-SS frequency point is lpssResult = -96dBm. Since -85dBm > -90dBm and -96dBm > -100dBm, conditions one and two are satisfied. Therefore, the terminal device sends the measurement results to the network device via a measurement report. Similarly, the terminal device can determine whether the conditions corresponding to the Ay event are met based on the measurement results, and thus decide whether to send the measurement results to the network device via a measurement report.

[0277] Measurement reports may also include information such as measurement identifiers or report configuration identifiers to indicate report configuration information, such as signal quality parameters and event identifiers.

[0278] The signal quality (measurement result) of the first and second synchronization signals can be sent through the same measurement report or through different measurement reports. For example, if measObject 0 in Table 3 indicates the first and second synchronization signals and is associated with the same report configuration identifier, report config 0 (as shown in Table 2), then the signal quality of the first and second synchronization signals can be sent in the same measurement report. If measObject 1 in Table 4 indicates the first synchronization signal and measObject 2 in Table 5 indicates the second synchronization signal and is associated with different report configuration identifiers, report config 3 and report config 2 respectively, then the signal quality of the first and second synchronization signals can be sent in different measurement reports.

[0279] In some cases, the measurement report may include only the signal quality of one of the first and second synchronization signals. For example, when the conditions of the Ax event are met, lpssResult is sent but ssResult is not.

[0280] S905. The network device sends an activation or deactivation low-power wake-up signal indication message to the terminal device. Correspondingly, the terminal device receives the activation or deactivation low-power wake-up signal indication message from the network device.

[0281] The activation or deactivation indication information for the low-power wake-up signal can serve as a second indication. The network device can determine whether to activate or deactivate the monitoring of the low-power wake-up signal of the terminal device based on the measurement report. For example, the network device obtains the measurement results from the measurement report, compares the measurement results with the threshold of event Ax or Ay in the report configuration information, determines that the first condition or the second condition is met, and then sends the activation or deactivation indication information for the low-power wake-up signal to the terminal device.

[0282] In another implementation, the network device receives a measurement report and obtains the corresponding event identifier through the measurement identifier or report configuration identifier in the measurement report. For example, if the event identifier is Ax, it is determined that the first condition is met and an instruction to activate the low-power wake-up signal is sent to the terminal device. If the event identifier is Ay, it is determined that the second condition is met and an instruction to deactivate is sent to the terminal device.

[0283] Activation or deactivation indication information can be sent via activation or deactivation signaling messages. These signaling messages can be data link layer signaling messages, such as those from the medium access control (MAC) layer, radio link control (RLC) layer, packet data convergence protocol (PDCP) layer, or service data adaptation protocol (SDAP) layer.

[0284] The activation or deactivation indication information can be a message name, which indicates whether the terminal device is activating or deactivating the monitoring of the low-power wake-up signal. Alternatively, it can be indicated by indication information carried in the signaling message. For example, the activation or deactivation indication information can be a function indicator bit, where a function indicator bit of 1 indicates activation and a function indicator bit of 0 indicates deactivation. It may also be other specific values ​​or characters.

[0285] After receiving activation or deactivation indication information, the terminal device initiates monitoring of low-power wake-up signals, such as according to... Figure 5 or Figure 6 The method shown implements the low-power wake-up signal monitoring function. For details, please refer to the previous text for a detailed explanation, which will not be repeated here.

[0286] In this embodiment, S902 and S905 are related to whether the terminal device performs low-power wake-up signal monitoring. In some other scenarios, S902 and S905 are optional. Relatedly, in some cases, the network device may also determine whether to enable the terminal device's low-power wake-up signal monitoring function based on its own capability information and network information. Therefore, step S901 is also optional. In some cases, the information to be sent in step S903 can also be sent using the same signaling message as in step S902. Therefore, in some cases, steps S902 and S903 can be combined.

[0287] In the implementation method described in this application, the network device can set different events and thresholds. The terminal device can then determine whether to send a measurement report to the network device based on these events and thresholds. The network device can then determine whether to activate or deactivate the monitoring of the terminal device's low-power wake-up signal based on the information in the measurement report. This implementation method allows for on-demand activation and deactivation of the terminal device, reducing the energy consumption caused by continuous low-power wake-up signal monitoring.

[0288] Figure 10 This is another implementation method for reporting third-party information through measurement reports. Specifically, it includes steps S1001 to S1005, which will be described in detail below.

[0289] S1001, The terminal device sends user capability information (e.g., low-power receiver type) to the network device. Accordingly, the network device receives the user capability information from the terminal device.

[0290] S1002. Monitoring of low-power wake-up signals of network devices enabling terminal devices.

[0291] S1003, the network device sends the measurement object (SS frequency point, LP-SS frequency point) and report configuration information (Ax1, Ax2, and Ay event information) to the terminal device. Correspondingly, the terminal device receives the measurement object and report configuration information from the network device.

[0292] The measurement objects, report configuration information format, report configuration information event triggering mechanism, Ay event, the correspondence between measurement objects and report configuration information, and information sending and receiving methods can all be found in [reference]. Figure 9 The detailed descriptions in the embodiments are not repeated here.

[0293] Regarding the specific events in the report configuration information Figure 9In this embodiment, event Ax is associated with both condition one and condition two. In this application embodiment, event Ax can be split into two associated events, Ax1 and Ax2, which respectively indicate condition one that the first synchronization signal needs to satisfy and condition two that the second synchronization signal needs to satisfy. For example, event Ax1 indicates that the measurement result at the SS frequency point satisfies condition one, and event Ax2 indicates that the measurement result at the LP-SS frequency point satisfies condition two.

[0294] For example, Table 6 is a report configuration information that contains information about events Ax1 and Ax2.

[0295] Table 6

[0296]

[0297] Wherein, the threshold corresponding to Ax1 is Ax1-ssThreshold, and the measurement result ssResult at the SS frequency point satisfies the following relationship: when ssResult>=Ax1-ssThreshold, the Ax1 event occurs. The threshold corresponding to Ax2 is Ax2-ssThreshold, and the measurement result lpssResult at the LP-SS frequency point satisfies the following relationship: when lpssResult>=Ax2-ssThreshold, the Ax2 event occurs.

[0298] The relationship between events Ax1 and Ax2 can be such that when event Ax1 occurs, event Ax2 is evaluated; when event Ax1 does not occur, event Ax2 is not evaluated. This relationship can also be described as event Ax1 triggering event Ax2.

[0299] One possible implementation is that the terminal device measures the synchronization signal of the SS frequency point, and uses the measurement result ssResul to determine whether condition one of the Ax1 event is met. If it is met, the synchronization signal of the LP-SS frequency point is measured; otherwise, the synchronization signal of the LP-SS frequency point is not measured. Another possible implementation is that the terminal device measures the synchronization signals of both the SS and LP-SS frequencies, but only performs the condition two judgment for the Ax2 event after the Ax1 event occurs.

[0300] The association between events Ax1 and Ax2 can be pre-configured in the terminal device and / or network device, or it can be indicated through report configuration information, such as Ax1triggerAx2 indicating this association in Table 6. For example, when Ax1triggerAx2 is 1, it indicates that the conditional judgment of event Ax2 needs to be triggered when event Ax1 occurs. When Ax1triggerAx2 is 0, it indicates that the conditional judgment of events Ax1 and Ax2 is independent, meaning that event Ax2 does not depend on whether event Ax1 occurs.

[0301] S1004. The terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report from the terminal device.

[0302] Corresponding to the report configuration information, the terminal device can send a measurement report to the network device after the event conditions are met, which includes the measurement results. For example, a measurement report is sent when both events Ax1 and Ax2 are met, or when event Ay is met.

[0303] For example, referring to the report configuration information shown in Table 6, the report configuration identifier is reportConfig3. If the measurement configuration information in Tables 4 and 5 is used, the measurement objects SS frequency point and LP-SS frequency point are both associated with reportConfig3.

[0304] Measurement reports for events Ax1 and Ax2 can be sent separately. Specifically, if event Ax1 is satisfied, an Ax1 measurement report is sent, containing the measurement result ssResult; if event Ax2 is satisfied, an Ax2 measurement report is sent, containing the measurement result lpssResult. Alternatively, measurement reports for events Ax1 and Ax2 can be sent together, with both ssResult and lpssResult included in the report.

[0305] Alternatively, the terminal device may send only the measurement report of the Ax2 event, with the measurement results including lpssResult but not ssResult.

[0306] For other information regarding measurement reports, the Ay event and its corresponding measurement reports, and how to send reports, please refer to [link / reference needed]. Figure 9 The relevant descriptions in the illustrated embodiments will not be repeated here.

[0307] S1005. The network device sends an activation or deactivation low-power wake-up signal indication message to the terminal device. Correspondingly, the terminal device receives the activation or deactivation low-power wake-up signal indication message from the network device.

[0308] Network devices can determine whether to activate or deactivate the low-power wake-up signal monitoring function of terminal devices based on measurement reports. For example, if the received measurement report corresponds to Ax1 and Ax2, or only Ax2, the network device can determine that a first condition is met and send an activation low-power wake-up signal indication message to the terminal device; if the received measurement report corresponds to Ay, the network device can send a deactivation low-power wake-up signal indication message to the terminal device.

[0309] Steps S1001 and S1002 in the embodiments of this application can be referred to Figure 9 The detailed description in the embodiments shows that steps S1001, S1002, and S1005 are optional, and can also be found in the following references. Figure 9 The detailed descriptions in the embodiments are not repeated here.

[0310] The correlation between events Ax1 and Ax2 in this embodiment can also be similarly applied to... Figure 9 In the method of the embodiment, for example, the association between Ax-ssThreshold and Ax-lpssThreshold is configured in the Ax event information, indicating that when the signal quality of the synchronization signal at the SS frequency point is greater than Ax-ssThreshold, the signal quality of the synchronization signal at the LP-SS frequency point is measured; or when the signal quality of the synchronization signal at the SS frequency point is greater than Ax-ssThreshold, it is determined whether the signal quality of the synchronization signal at the LP-SS frequency point is greater than Ax-lpssThreshold. Thus, the terminal device determines whether to send a measurement report.

[0311] In the implementation method described in this application, the network device can set different events and thresholds. The terminal device can then determine whether to send a measurement report to the network device based on these events and thresholds. The network device can then determine whether to activate or deactivate the monitoring of the terminal device's low-power wake-up signal based on the information in the measurement report. Through the implementation method described in this application, the terminal device can be activated and deactivated as needed, reducing the energy consumption caused by the terminal device continuously monitoring the low-power wake-up signal. Furthermore, if one event (e.g., condition one) is not met, the terminal device can avoid performing the operation related to another event (e.g., condition two), reducing the overhead of data processing and further saving the terminal device's energy consumption.

[0312] Figure 11 Another implementation method for reporting third-party information via measurement reports. Specifically, it includes steps S1101 to S1105, which will be described in detail below.

[0313] S1101, The terminal device sends user capability information (e.g., low-power receiver type) to the network device. Accordingly, the network device receives the user capability information from the terminal device.

[0314] S1102. Monitoring of low-power wake-up signals of network devices enabling terminal devices.

[0315] S1103, The network device sends measurement object and report configuration information (A1 event information and A2 event information related to LP-SS) to the terminal device. Correspondingly, the terminal device receives the measurement object and report configuration information from the network device.

[0316] The measurement objects, report configuration information, event triggering mechanisms, the correspondence between measurement objects and report configuration information, and information sending and receiving methods can all be found in [reference]. Figure 9 or Figure 10 The detailed descriptions in the embodiments are not repeated here.

[0317] In this embodiment of the application, the report configuration information may include information about events A1 and / or A2. The information about events A1 and A2 only includes the threshold of the first synchronization signal (which may correspond to...). Figure 7 The third threshold in the embodiment does not include the threshold of the second synchronization signal. When determining whether an event is satisfied (or an event occurs), it can be determined whether a specific relationship is satisfied between the measurement result of the first synchronization signal (e.g., ssResult) and the corresponding threshold, which is called a condition. The condition corresponding to event A1 is the first condition, and the condition corresponding to event A2 is the second condition.

[0318] For example, the report configuration information is shown in Table 7. The threshold value corresponding to event A1 is A1-ssThreshold, the threshold value corresponding to event A2 is A2-ssThreshold, and the measurement result of the first synchronization signal is ssResult. Accordingly, the first condition can be that ssResult and A1-ssThreshold satisfy the following relationship:

[0319] ssResult>=A1-ssThreshold.

[0320] The second condition can be that ssResult and A2-ssThreshold satisfy the following relationship:

[0321] ssResult <= A2 - ssThreshold.

[0322] Table 7

[0323]

[0324] In this embodiment of the application, the report configuration information may further include first indication information, which is used to indicate the signal quality of whether to send a second synchronization signal when the A1 event or the A2 event is met.

[0325] For example, the information to be included in the measurement report can be indicated in the reportQuantity field in Table 7. One possible indication is that if reportQuantity includes the fields ss-RSRP, lpss-RSRP, ss-RSRQ, and lpss-RSRQ, then, when either the first or second condition is met, the measurement report will include the measurement results of the RSRP and RSRQ of the synchronization signal (first synchronization signal) at the SS frequency point, as well as the measurement results of the RSRP and RSRQ of the synchronization signal (second synchronization signal) at the LP-SS frequency point. If reportQuantity only includes lpss-RSRP, then the measurement report will only report the measurement result of the RSRP of the synchronization signal at the LP-SS frequency point.

[0326] Another possible indication method involves configuring indicator bits in `reportQuantity` to indicate whether SS-RSRP, LPSS-RSRP, SS-RSRQ, and LPSS-RSRQ should be reported. For example, setting the SS-RSRP indicator bit to 1 or true indicates that the measurement report should include the RSRP measurement results of the synchronization signal at the SS frequency. Setting the LPSS-RSRP indicator bit to 1 or true indicates that the measurement report should include the RSRP measurement results of the synchronization signal at the LP-SS frequency. SS-RSRQ and LPSS-RSRQ can also be indicated using similar indicator bits. Specifically, the indicator bits can also take other forms or have other correspondences, which are not limited in this embodiment.

[0327] S1104. The terminal device sends a measurement report to the network device. Accordingly, the network device receives the measurement report from the terminal device.

[0328] Corresponding to the report configuration information, the terminal device can send a measurement report to the network device after the event conditions are met, which includes the measurement results. Specifically, the measurement results included in the measurement report can be referred to the description in step S1103.

[0329] S1105. The network device sends an activation or deactivation low-power wake-up signal indication message to the terminal device. Correspondingly, the terminal device receives the activation or deactivation low-power wake-up signal indication message from the network device.

[0330] Except for the descriptions of the conditions corresponding to events A1 and A2, the other processes in this embodiment can be referred to the foregoing. Figure 7 , Figure 9 or Figure 10 The detailed descriptions of the relevant steps and information in the corresponding embodiments are not repeated here.

[0331] In the implementation method described in this application, the network device can establish a relationship between the second synchronization signal and the event by setting event information related to the first synchronization signal, including first indication information. This allows the first event to trigger the reporting of the signal quality of the second synchronization signal, and the terminal device can determine whether to send third information solely based on the signal quality of the first synchronization signal. The method described in this application simplifies the judgment logic of the terminal device and reduces the complexity of signal processing for the terminal device.

[0332] Figure 12 This is another implementation method for reporting third-party information via UAI. Specifically, it includes steps S1201 to S1204, which will be described in detail below.

[0333] S1201, The terminal device sends user capability information (low-power receiver type) to the network device. Accordingly, the network device receives the user capability information from the terminal device.

[0334] S1202 Monitoring of low-power wake-up signals of network device enabling terminal devices (measurement object, UAI transmission threshold).

[0335] When enabling terminal devices, network devices can carry the measurement object and UAI transmission threshold.

[0336] The UAI transmission threshold is used to indicate that when the signal quality of the measured object meets a certain relationship with the threshold, the measurement result of the measured object is transmitted. The UAI transmission threshold may include an activation threshold for the SS frequency point, a deactivation threshold for the SS frequency point, an activation threshold for the LP-SS frequency point, and a deactivation threshold for the LP-SS frequency point. Specifically, the monitoring and measurement object enabling the low-power wake-up signal, the signal quality, etc., can be referred to the description in the foregoing embodiments, and the relationship between the measurement result and the UAI transmission threshold can be referred to... Figure 7 The descriptions of conditions one through four in the embodiments are not repeated here.

[0337] S1203. The terminal device sends the UAI (measurement result) to the network device. Correspondingly, the network device receives the UAI from the terminal device.

[0338] UAI can include measurement results, such as ssResult and lpssResult. UAI information can also include indications of whether the first condition is met, such as an indication bit of 1 indicating that the first condition is met, and an indication bit of 0 indicating that the second condition is met. The specific indication information may also take other forms, which are not limited here.

[0339] S1204, Activation or deactivation of low-power wake-up signal indication information.

[0340] Steps S1201, S1202, and S1204 in the embodiments of this application can be referred to Figure 9 or Figure 10 or Figure 11 The detailed explanations in the text are omitted here.

[0341] In the implementation method described in this application, the terminal device can send a User Information Acquisition (UAI) to the network device based on a threshold. The network device can then determine whether to activate or deactivate the terminal device's low-power wake-up signal monitoring based on the information in the UAI. Through this implementation method, the network device can activate and deactivate the terminal device as needed, reducing the energy consumption caused by the terminal device continuously monitoring for low-power wake-up signals. Furthermore, sending third-party information via UAI can reduce resource consumption associated with data transmission and processing.
