[0032] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0033] A-IoT

[0034] A-IoT communication uses energy harvesting and backscatter communication technology. The so-called A-IoT device refers to an IoT device that uses various environmental energies, such as wireless radio frequency energy, light energy, solar energy, thermal energy, mechanical energy, etc. to drive itself. This device can have no energy storage capacity or very limited energy storage capacity (such as using capacitors with a capacity of tens of microfarads (uF)). Compared with traditional Internet of Things (IoT) devices, A-IoT devices have many advantages such as no conventional battery, no maintenance, small size, low complexity and low cost, and long life cycle.

[0035] In some scenarios, A-IoT devices can also be called zero-power devices.

[0036] The environmental IoT may include a network device 110 and an A-IoT device 120, such as Figure 1 As shown. The network device is used to send wireless power supply signals, downlink communication signals and receive backscatter signals from A-IoT devices. A basic A-IoT device includes an energy harvesting module, a backscatter communication module and a low-power computing module. In addition, the A-IoT device may also have a memory or sensor to store some basic information (such as item identification, etc.) or obtain sensor data such as ambient temperature and ambient humidity.

[0037] It should be noted that Figure 1A network device and an A-IoT device are shown exemplarily. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of A-IoT devices within its coverage area, which is not limited in the embodiments of the present application.

[0038] In addition, in some implementations, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0039] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: the fifth generation (5th generation, 5G) system or new radio (new radio, NR), long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD), cellular Internet of Things, etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, etc.

[0040] The A-IoT device in the embodiment of the present application can be used as a terminal device, which can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal device, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application can be a device that provides voice and / or data connectivity to the user, which can be used to connect people, objects and machines, such as household appliances, sensors, electronic tags, etc. with wireless connection functions. The terminal in the embodiment of the present application can be a wireless terminal in a smart home, a wireless terminal in an IWSN, a wireless terminal in smart logistics and smart warehousing, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, etc.

[0041] The network device in the embodiment of the present application may be a device for communicating with a terminal device. If the terminal is an electronic tag, the network device may be a reader / writer for reading and writing the electronic tag (for example, a reader / writer based on radio frequency identification (RFID) technology). The network device may also be an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a wireless access network (RAN) node (or device) that connects the terminal device to a wireless network. Base station can broadly cover various names as follows, or replace with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, auxiliary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, a modem or a chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), machine-to-machine (M2M) communications, a network-side device in a 6G network, and a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form used by the network equipment.

[0042] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0043] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU.

[0044] The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network equipment and terminal equipment are located.

[0045] It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform).

[0046] In some implementations, the terminal 120 may include an energy collection module 121 and a backscatter communication module 122. Figures 2 to 4 The energy collection module 121 and the backscatter communication module 122 are introduced, and will not be repeated here for the sake of brevity. In some cases, the terminal 120 may also include a low-power computing module 123. Among them, the low-power computing module 123 is used to provide computing functions for the terminal, such as data processing, etc. In other cases, the terminal 120 may also include a sensor 124 for collecting external information (for example, ambient temperature, ambient humidity, etc.). In other cases, the terminal 120 may also include a memory 125 for storing some information (for example, external information collected by the above-mentioned sensors, or such as item identification, etc.).

[0047] The energy collection module 121 is used to collect energy. In some implementations, energy can be collected through a wireless power supply signal sent by a network device. The wireless power supply signal can be a "radio frequency signal" sent by a network device, so the energy collection module is also called a "radio frequency energy collection module."

[0048] Figure 2 A possible structure of the energy harvesting module is shown. Figure 2As shown, the energy collection module 121 can collect the energy of the spatial electromagnetic waves of the radio frequency signal based on the principle of electromagnetic induction, and store the collected energy in the capacitor C, which is the charging process of the capacitor C. When the charging process of the capacitor C is completed, the capacitor C can start to discharge to provide energy for the terminal operation. For example, the discharge of the capacitor C can be used to drive the terminal to perform low-power demodulation on the data sent by the network device. For another example, the discharge of the capacitor C can be used to drive the terminal to modulate the data to be sent. For another example, the discharge of the capacitor C can be used to drive the sensor of the terminal to collect data. For another example, the discharge of the capacitor C can be used to drive the terminal to read the data in the memory 125, etc.

[0049] The backscatter communication module 122 is used for backscattering communication between the terminal and the network device. Figure 3 Introduce the backscatter communication principle of the embodiment of the present application. Figure 3 , the terminal 120 receives the wireless signal sent by the network device 110, and modulates the wireless signal to load the information to be sent. Finally, the modulated signal is radiated from the antenna. This information transmission process is called backscatter communication. Among them, backscatter communication and load modulation functions are inseparable. Load modulation adjusts and controls the circuit parameters of the terminal's oscillation circuit according to the beat of the data stream, so that parameters such as the size of the terminal impedance change accordingly, thereby completing the modulation process. Load modulation technology mainly includes two methods: resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel to the load, and the resistor is turned on or off based on the control of the binary data stream, as follows Figure 4 As shown. The on-off of the resistor will cause the circuit voltage to change, thus realizing amplitude-shift keying (ASK) modulation, that is, the signal is modulated and transmitted by adjusting the amplitude of the backscattered signal of the terminal. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by turning the capacitor on and off, realizing frequency-shift keying (FSK) modulation, that is, the signal is modulated and transmitted by adjusting the operating frequency of the backscattered signal of the terminal.

[0050] In some implementations, the transmission (transport, TX) path of the network device 110 may be provided with other devices for processing the signal to be transmitted, such as an amplifier (AMP), etc. The reception (receive, RX) path of the network device 110 may be provided with other devices for processing the received signal, such as a low noise amplifier (LNA), etc.

[0051] In other implementations, the terminal 120 may be provided with an energy collection unit for collecting energy from the wireless power supply signal sent by the network device. Of course, the terminal 120 may also be provided with a logic processing unit to perform corresponding calculation functions.

[0052] It should be noted that, whether it is the network device 110 or the terminal 120, Figure 3 The connection structure of the signal processing circuit is shown only as an example, and the processing circuit of the network device 110 and / or the terminal 120 may include other elements, which is not specifically limited in the embodiments of the present application.

[0053] Generally, the load modulation function can be realized by two methods: resistance load modulation and capacitance load modulation. Figure 4 The circuit diagram of the terminal based on the resistance load modulation technology is shown. It should be noted that: Figure 4 The circuit described implements the load modulation technology in a manner similar to the existing circuits implementing the load modulation technology. For simplicity, Figure 4 The functions of the resistors R2 and R3, capacitors C1 and C2, and inductors L1 and L2 shown in the figure are not repeated any more.

[0054] In resistive load modulation, a resistor R can be connected in parallel with the load. L The switch S can be controlled based on the binary data flow to realize the resistor R L In this way, the resistor R L The on-off of the terminal will cause the circuit voltage to change, and the change of the circuit voltage can control the amplitude of the backscattered signal of the terminal, thereby realizing the modulation of the backscattered signal, that is, ASK modulation of the backscattered signal.

[0055] Similarly, in capacitive load modulation, the on-off of the capacitor can be controlled based on a binary data stream to change the circuit resonant frequency, thereby changing the operating frequency of the backscattered signal to achieve FSK modulation.

[0056] As described above, the terminal can modulate the incoming signal (i.e., the signal sent by the network device) by means of load modulation, thereby realizing the backscatter communication process. Therefore, the terminal in the backscatter communication usually has the following advantages.

[0057] Advantage 1: Since the terminal does not need to actively transmit signals, there is no need to construct a complex RF path. For example, the RF path does not need to include devices such as a power amplifier (PA) and a RF filter, thereby reducing the cost and size of the terminal.

[0058] The second advantage is that since the terminal does not need to actively generate high-frequency signals, a high-frequency crystal oscillator is not required, thereby reducing the cost and size of the terminal.

[0059] Advantage three: Since the terminal can use backscatter technology to communicate with network equipment, the terminal consumes less energy during communication and does not even need to consume its own energy.

[0060] Classification of A-IoT devices

[0061] In some scenarios, A-IoT devices can be divided into three categories based on their energy sources and energy usage: passive A-IoT devices, semi-passive A-IoT devices, and active A-IoT devices.

[0062] 1. Passive A-IoT devices.

[0063] Passive A-IoT devices usually do not need built-in batteries. When the A-IoT device is close to the network device, the A-IoT device is in the near field formed by the radiation of the network device antenna. At this time, the antenna of the A-IoT device can generate an induced current through electromagnetic induction. The induced current can power the A-IoT device to achieve demodulation of the received signal and / or modulation and encoding of the transmitted signal. In some implementations, the above-mentioned passive A-IoT device can be an electronic tag, and accordingly, the network device can be a reader / writer of a (radio frequency identification, RFID) system, which is used to read the content in the electronic tag and / or to change the content in the electronic tag.

[0064] 2. Semi-passive A-IoT devices

[0065] The semi-passive A-IoT device itself does not have a conventional battery installed, but can use the energy collection module 121 to collect radio wave energy and store the collected energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can provide energy for the A-IoT device to realize the demodulation of the received signal and / or the modulation and encoding of the transmitted signal.

[0066] Active A-IoT Devices

[0067] Active A-IoT devices can have built-in batteries. The battery can power the A-IoT device to demodulate the received signal and / or modulate and encode the transmitted signal. However, when the A-IoT device uses backscatter technology to communicate, the A-IoT device does not need to consume battery energy. Therefore, for such an A-IoT device, "zero power consumption" is mainly reflected in the scenario where the terminal uses backscatter technology to communicate.

[0068] In some implementations, the active A-IoT device may be an electronic tag, and the network device may be an RFID reader / writer. In this case, the built-in battery may supply power to the RFID chip in the A-IoT device to increase the reading and writing distance between the RFID reader / writer and the electronic tag. On the other hand, the built-in battery may supply power to the RFID chip in the A-IoT device to shorten the reading and writing delay of the RFID reader / writer to the electronic tag, which is beneficial to improving the reliability of communication.

[0069] In other scenarios, A-IoT devices can be divided into three categories based on transmitter type, including the following types: A-IoT devices based on backscattering, A-IoT devices based on active transmitters, and A-IoT devices with both backscattering and active transmitters.

[0070] 1) A-IoT devices based on backscattering.

[0071] This type of A-IoT device uses the backscattering method as described above to send uplink data. This type of device does not have an active transmitter for active transmission, but only has a backscattering transmitter. Therefore, when this type of terminal sends data, the network device needs to provide a carrier, and this type of terminal device performs backscattering based on the carrier to achieve data transmission.

[0072] 2) A-IoT devices based on active transmitters.

[0073] This type of A-IoT device uses an active transmitter with active transmission capability for uplink data transmission. Therefore, when sending data, this type of A-IoT device can use its own active transmitter to send data without the need for network equipment to provide a carrier. Active transmitters suitable for A-IoT devices can be, for example, ultra-low power ASK and ultra-low power FSK transmitters. Based on current implementations, when transmitting a 100uw signal, the overall power consumption of this type of transmitter can be reduced to 400-600uw.

[0074] 3) A-IoT devices with both backscatter and active transmitters.

[0075] This type of terminal supports both backscattering and active transmitters. The terminal can determine which uplink signal transmission method to use based on different situations (such as power conditions, available environmental energy) or based on the scheduling of network equipment: backscattering or active transmission using an active transmitter.

[0076] Low-power IoT based on cellular networks

[0077] Cellular Internet of Things is booming. For example, 3GPP has standardized Internet of Things technologies such as narrow band internet of things (NB-IoT), machine type communication (MTC), and reduced capability (RedCap). However, there are still many scenarios where IoT communication needs cannot be met using existing technologies, such as harsh communication environments (high temperature, extremely low temperature, high humidity, high pressure, high radiation or high-speed movement, etc.), extremely small terminal form requirements, and extremely low cost.

[0078] Therefore, in order to cover these unmet IoT communication needs, and to further make full use of the communication capabilities of wireless cellular networks to achieve the effect of interconnecting everything, it is also necessary to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT in cellular networks, and the Environmental IoT can just meet this demand.

[0079] Based on the discussion of A-IoT application scenarios in 3GPP system architecture (SA)1, A-IoT can be used in at least the following four scenarios:

[0080] Object recognition, such as logistics, production line product management, and supply chain management.

[0081] Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment.

[0082] Positioning, such as indoor positioning, intelligent object search, and production line item positioning.

[0083] Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0084] In low-power IoT based on cellular networks, A-IoT devices can directly transmit and receive carriers, data or signals from base stations, and send or backscatter data or channels to base stations, such as Figure 5 As shown (recorded as the first topology). Alternatively, the communication between A-IoT and the base station is realized through an intermediate node. In this case, the intermediate node sends a carrier, data or signal to the A-IoT device, the A-IoT device sends or backscatters data or signals to the intermediate node, and the intermediate node sends the received data or signal to the base station, as shown in FIG. Figure 6 As shown (recorded as the second topology).

[0085] From the above description, it can be known that passive AIoT devices do not require built-in batteries, but are only equipped with a small energy storage device to collect energy from the surrounding environment, such as sunlight, wind, radio frequency signals, etc., and store it in its own energy storage device. When communication is required, a short, small amount of data is transmitted with the network. In order to save power consumption, when the passive AIoT device is not transmitting data, it does not need to maintain downlink synchronization with the cellular wireless communication network. Only when data needs to be transmitted will it perform downlink synchronization, receive paging messages, etc., and shut down immediately after completing the data transmission. In the embodiment of the present application, energy may also be referred to as "electricity" or "electrical energy."

[0086] Figure 7 This is a diagram of the energy accumulation of AIoT devices. The horizontal axis is time, and the vertical axis is the stored energy level of the AIoT device. In the initial state, the AIoT device has no energy (0). As time goes by, the AIoT device collects energy from the environment, that is, it uses energy pulses for charging, but a small amount of energy leakage will occur during the charging process.

[0087] When the energy accumulation of the AIoT device reaches the level of receiving, it can receive downlink data; when the energy accumulation of the AIoT device reaches the level of sending, it can send uplink data. Figure 7 As shown, the energy required for the AIoT device to retain the state is the lowest, and the retained state is used to save data in the cache, etc. The energy required to receive downlink data is second, and the energy required to send uplink data is the highest.

[0088] The traditional communication process is designed for active terminal devices. Although the power saving of terminal devices is also taken into consideration when designing the process, even the most power-saving NB-IoT in the existing network has a much greater energy supply than AIoT. Therefore, the communication process needs to be redesigned for AIoT devices.

[0089] In traditional technologies, except for the service wake-up paging (paging) and system information block (SIB) changes in multimedia broadcast multicast service (MBMS), other paging messages are for a single terminal device (per UE). However, there are too many terminal devices in AIoT devices, so there will be a large number of processes for AIoT terminal devices. In order to save the wireless resource consumption caused by paging messages and simplify the paging process on the network side, SA2 introduces group-based (pre-group) paging, such as Figure 8Specifically, the paging message between the access and mobility management function (AMF) network element and the base station is changed to be transmitted based on the group of each terminal device.

[0090] In some scenarios, group-based paging is also called group paging, and the corresponding group is called a "paging group". The paging group here is defined by the application layer or the core network. For the base station, there are two ways to handle the paging group: visible and invisible. The base station is visible to the paging group, which means that the base station can map the paging group into a list of terminal device identities (for example, a UE identity (identity, ID) list), so it can reuse the existing air interface paging message format and send a paging message to a single terminal device at the paging opportunity corresponding to each terminal device; the base station is not visible to the paging group, which means that the base station cannot map the paging group into a list of terminal device identities, so the air interface paging mechanism cannot be reused.

[0091] like Figure 8 As shown, the process in the upper solid box represents paging based on terminal devices. AMF sends a paging message to the terminal device through the base station. Terminal device 1 and terminal device 2 both receive the paging message, but the paging object is terminal device 1, so only terminal device 1 responds to the paging message and establishes a connection with the network device. The process in the lower dotted box represents group-based paging. AMF sends a paging message to the terminal device through the base station. The paging message is used to page the first paging group. Terminal device 1 and terminal device 2 both belong to the first paging group, so they both respond to the paging message and establish a connection with the network device.

[0092] As can be seen from the above, in some scenarios, the terminal device (e.g., AIoT device) can perform sending or receiving operations only after collecting a certain amount of energy. Conversely, when the terminal device does not collect enough energy, the terminal device cannot perform sending or receiving operations. However, the traditional paging mechanism is designed based on the working assumption that the terminal device must be able to respond to the first paging message, which may not be applicable to the terminal device in this scenario.

[0093] For example, in the traditional paging solution, for downlink data, the terminal device will listen to the paging message at the paging time. If there is downlink data for the terminal device, the network device (for example, the base station) will send a paging message at the paging time of the terminal device. After receiving the paging message, the terminal device will establish a connection with the network device to receive the downlink data. For the terminal device, the above process design is based on two working assumptions:

[0094] Assumption 1: As long as there is a paging message for itself, it means that the network device must have the downlink data of the terminal device.

[0095] Assumption 2: As long as the terminal device receives a paging message, it can establish a connection with the network, and the energy of the terminal device must be able to support the behavior of "establishing a connection".

[0096] If the terminal device is the AIoT device mentioned above, the above two working assumptions may not be true. For assumption 1, 3GPP has decided that network devices can send paging messages to terminal devices without downlink data. This process can be used for asset inventory. For assumption 2, since the power consumption of sending is much higher than that of receiving, the fact that the AIoT device can receive paging messages does not mean that the AIoT device can definitely initiate random access, connection establishment and other processes. Therefore, the traditional paging mechanism is not suitable for AIoT devices.

[0097] In response to the above problems, an embodiment of the present application provides a wireless communication method, in which a network device sends a first paging message to a terminal device, and the terminal device determines whether to respond to the first paging message or not, which helps to improve the flexibility of data transmission.

[0098] Combined with the following Fig. 9 A wireless communication method according to an embodiment of the present application is introduced. Fig. 9 It is a schematic flowchart of the wireless communication method of an embodiment of the present application. Fig. 9 The method shown includes steps S910 and S920.

[0099] In step S910, the network device sends a first paging message to the terminal device. Accordingly, the terminal device can monitor the first paging message.

[0100] In some implementations, the first paging message is transmitted within a first paging window, that is, within the first paging window, the network device sends the first paging message to the terminal device. Accordingly, the terminal device can monitor the first paging message within the first paging window.

[0101] In some implementations, the length of the first paging window can ensure that within the first paging window, energy accumulated by the terminal device can be used to receive the first paging message.

[0102] In some implementations, the length of the first paging window is associated with one or more of the following: a manner in which the terminal device acquires energy, and an efficiency in which the terminal device acquires energy.

[0103] In some implementations, the terminal device may obtain energy in one or more ways. For example, the terminal device may obtain energy through solar panels or wind energy, and the length of the first paging window corresponding to the terminal device may be determined based on these two ways of obtaining energy.

[0104] In some implementations, different terminal devices may obtain energy in different ways, and accordingly, the lengths of the first paging windows of different terminal devices may also be different. For example, terminal device 1 obtains energy through solar panels, and terminal device 2 obtains energy through wind energy. Terminal device 1 obtains energy faster than terminal device 2, so a shorter first paging window may be configured for terminal device 1, and a longer first paging window may be configured for terminal device 2. Of course, in the embodiment of the present application, different terminal devices may obtain energy in the same way.

[0105] In some implementations, the efficiency of the terminal device in obtaining energy can have one or more values, and accordingly, one or more lengths of the first paging window can be configured for the terminal device. For example, the terminal device obtains energy through a solar panel, and its efficiency in obtaining energy will change over time. During the day, the efficiency of the terminal device in obtaining energy through the solar panel is high, and the terminal device can accumulate enough energy in a short time to receive the first paging message, so a shorter first paging window is configured for the terminal device during the day; at night, the efficiency of the terminal device in obtaining energy through the solar panel is low, and the terminal device needs a long time to accumulate enough energy to receive the first paging message, so a longer first paging window is configured for the terminal device at night. For another example, also during the day, when the weather is clear, the efficiency of the terminal device in obtaining energy through the solar panel is high, so a shorter first paging window is configured for the terminal device; when it rains, the efficiency of the terminal device in obtaining energy through the solar panel is low, so a longer first paging window is configured for the terminal device.

[0106] In some implementations, the length of the first paging window is configured by a network device. For example, the network device is a base station, and the base station configures the length of the first paging window for the terminal device.

[0107] In some implementations, the network device may configure a variety of first paging window lengths for the terminal device.

[0108] In some implementations, the lengths of the various first paging windows may be configured by the network device at one time, and accordingly, the terminal device determines which length of the first paging window to use. For example, the terminal device obtains energy through a solar panel, and the network device configures various lengths of the first paging window for the terminal device according to the external environment (e.g., cloudy, rainy, or sunny), and the terminal device determines which length of the first paging window to use according to the environmental changes.

[0109] In other implementations, the lengths of the multiple first paging windows may be configured multiple times by the network device. For example, the terminal device obtains energy through a solar panel, and when the weather is clear, the network device configures a length of the first paging window for the terminal device. When the environment changes (for example, the weather changes from clear to cloudy), the network device configures a length of the first paging window for the terminal device again.

[0110] In some implementations, the network device may obtain the energy acquisition method and / or the energy acquisition efficiency of the terminal device from the first network element. For example, the first network element may be a user database and / or an application server.

[0111] In other implementations, the way in which the terminal device acquires energy and / or the efficiency with which the terminal device acquires energy may be reported by the terminal device to the network device.

[0112] In some implementations, the length of the first paging window is at least enough to allow the terminal device to accumulate energy to receive the first paging message. Fig.10 At the beginning of the first paging window, the terminal device 1 does not have enough energy to receive the message, and the terminal device 1 may not monitor the first paging message, and the terminal device 1 continues to accumulate energy. When the energy is accumulated to support the reception of the message, the terminal device 1 monitors the first paging message. If the terminal device 1 finds that there is a first paging message for itself, the terminal device 1 can receive the first paging message.

[0113] In the embodiment of the present application, the first paging window may include one or more paging opportunities, and the paging opportunities carry the first paging message. That is, in the first paging window, the network device may send one or more first paging messages to the terminal device.

[0114] In the embodiment of the present application, the content of the multiple first paging messages is not limited. For example, the content of the multiple first paging messages may be the same. For another example, the content of the multiple first paging messages may be different.

[0115] In some implementations, the length of the first paging window can ensure that within the first paging window, the terminal device has sufficient energy to receive the first paging message at least once in the paging opportunity. In other words, the length of the first paging window can ensure that the terminal device receives the first paging message at least once within the first paging window.

[0116] In some implementations, the first paging message carries information indicating a paging reason.

[0117] In some implementations, the information used to indicate the paging reason is also referred to as "additional indication".

[0118] In some implementations, the paging reason includes one or more of the following: downlink data to be transmitted; whether the terminal device has uplink data to be transmitted; and an inventory of the terminal device.

[0119] In some implementations, the downlink data to be transmitted can be understood as the downlink data that the network device needs to transmit to the terminal device. For example, the access network device (such as a base station) stores the downlink data that needs to be transmitted to the terminal device. For another example, the core network element (such as a UPF) stores the downlink data that needs to be transmitted to the terminal device.

[0120] In some implementations, if the paging reason includes downlink data to be transmitted, the first paging message may indicate one or more of the following to the terminal device: the amount of downlink data to be transmitted; the range of the amount of downlink data to be transmitted; the remaining time from the downlink data to be transmitted to the transmission delay budget. Accordingly, the terminal device may determine whether the reception of the downlink data to be transmitted can be completed based on the relevant information of the downlink data to be transmitted and other information (for example, the current wireless signal quality of the terminal device).

[0121] In some implementations, if the paging reason includes downlink data to be transmitted, the first paging message can indicate one or more of the following to the terminal device: whether there is target data to be transmitted; the data volume of the target data; the data volume range of the target data; and the remaining time of the target data before the transmission delay budget.

[0122] In some implementations, the target data may be understood as data that times out before a second paging window, where the second paging window is the first paging window after the first paging window.

[0123] In some implementations, the target data is also referred to as “downlink urgent data”, ie, downlink data that times out before the second paging window.

[0124] In some implementations, if the paging reason includes whether the terminal device has uplink data to be transmitted, it can be understood that if the network device has no downlink data to be transmitted and the terminal device has uplink data to be transmitted, it responds to the first paging message; if the terminal device has no uplink data to be transmitted, it does not respond to the first paging message.

[0125] In some implementations, if the paging reason includes taking inventory of the terminal device, it can be understood that the network device expects the terminal device to report its identity.

[0126] Continue to see Fig. 9 In step S920, the terminal device determines whether to respond to or not to respond to the first paging message.

[0127] The following describes, in conjunction with Example 1, a related solution for a terminal device to determine whether to respond to or not to respond to a first paging message.

[0128] Embodiment 1: The terminal device determines whether to respond to or not to respond to the first paging message

[0129] In some implementations, the terminal device determines whether to respond to or not respond to the first paging message based on the second information.

[0130] In some implementations, the second information is used to indicate one or more of the following: energy of the terminal device, wireless signal quality of the terminal device, and data volume of data to be transmitted.

[0131] In some implementations, the energy of the terminal device can be understood as the current energy of the terminal device.

[0132] In some implementations, the wireless signal quality of the terminal device can be understood as the current wireless signal quality of the terminal device.

[0133] In some implementations, the wireless signal quality of a terminal device is also referred to as "wireless signal strength".

[0134] In an embodiment of the present application, the method for indicating the wireless signal quality of the terminal device is not limited. For example, the wireless signal quality of the terminal device can be one or more indicators that can indicate the quality of the wireless signal, such as reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), reference signal received signal-to-noise ratio (RSSNR), received signal strength indicator (RSSI), reference signal interference power (RSIP), received signal code power (RSCP), etc.

[0135] In some implementations, the data volume of the data to be transmitted may be understood as the data volume of the uplink data to be transmitted and / or the data volume of the downlink data to be transmitted.

[0136] In some implementations, the amount of downlink data to be transmitted can be understood as the amount of data that is about to arrive at the terminal device. For example, the network device side is about to send downlink data to the terminal device, and the downlink data is about to arrive at the terminal device. The amount of the downlink data is the amount of downlink data to be transmitted.

[0137] In some implementations, the amount of downlink data to be transmitted may be indicated to the terminal device by the first paging message.

[0138] In some implementations, the amount of uplink data to be transmitted can be understood as the amount of data in the terminal device buffer, or the amount of data that has reached the terminal device. For example, the amount of data that has reached the access layer of the terminal device is the amount of uplink data to be transmitted.

[0139] In some implementations, the amount of uplink data to be transmitted may be determined by the application layer of the terminal device. For example, the first paging message is used for inventory of the terminal device, and the application layer of the terminal device may determine the amount of uplink data to be transmitted based on information such as the type and model of the terminal device being inventoried.

[0140] In some implementations, the second information is used to indicate the energy of the terminal device. The terminal device determines whether to respond to or not to the first paging message based on the energy of the terminal device. It can be understood that if the first paging message includes a dedicated identifier assigned to the terminal device and the energy of the terminal device supports responding to the inventory, the terminal device can respond to the first paging message. For example, the first paging message carries the dedicated identifier of the terminal device (for example, the random access timing and / or the random access code), and the terminal device only needs to respond to the first paging message and initiate random access. Accordingly, the network device can determine that the terminal device has responded to the inventory through the random access timing and / or the random access code, and does not need to establish a connection with the network device. In this case, the terminal device requires less energy.

[0141] In some implementations, the second information is used to indicate the energy of the terminal device. The terminal device determines whether to respond to or not to the first paging message based on the energy of the terminal device. It can be understood that if the first paging message does not include a dedicated identifier assigned to the terminal device, and the energy of the terminal device supports responding to the inventory and establishing a connection with the network device, the terminal device can determine to respond to the first paging message. For example, the first paging message does not carry the dedicated identifier of the terminal device (such as the first paging message only indicates "terminal devices belonging to paging group A, please respond"), then the terminal device needs to establish a connection with the network device, and then respond to the inventory (i.e., report the identity). In this case, the terminal device requires more energy.

[0142] In some implementations, the second information is used to indicate the energy of the terminal device, and the terminal device determines whether to respond or not to the first paging message based on the energy of the terminal device. It can be understood that if the energy of the terminal device does not support response inventory, the terminal device may not respond to the first paging message.

[0143] In some implementations, the second information is used to indicate the energy of the terminal device, and the terminal device determines whether to respond to or not to the first paging message based on the energy of the terminal device. It can be understood that if the first paging message does not include a dedicated identifier assigned to the terminal device, but includes the identifier of the paging group to which the terminal device belongs, and the energy of the terminal device does not support responding to inventory and establishing a connection with a network device, the terminal device may not respond to the first paging message. For example, the first paging message does not carry the dedicated identifier of the terminal device, but includes the identifier of the paging group to which the terminal device belongs, then the terminal device needs to establish a connection with the network device and then respond to the inventory. However, the energy of the terminal device does not support responding to inventory and establishing a connection with a network device, so the terminal device may not respond to the first paging message.

[0144] In some implementations, the second information is used to indicate the energy of the terminal device and the amount of data to be transmitted. The terminal device determines whether to respond to the first paging message based on the energy of the terminal device and the amount of data to be transmitted. It can be understood that if the amount of data received by the terminal device that supports transmission is greater than or equal to the amount of data to be transmitted, the terminal device can respond to the first paging message. For example, see Fig.10 When the energy accumulated by the terminal device 1 is sufficient to receive the message, the terminal device 1 receives the first paging message. If the amount of data supported by the energy accumulated by the terminal device 1 is greater than or equal to the amount of data to be transmitted, the terminal device 1 can respond to the first paging message (for example, establish a connection with the network device and transmit data).

[0145] In some implementations, the data volume of the above-mentioned data to be transmitted may be the data volume of uplink data to be transmitted and / or the data volume of downlink data to be transmitted. For example, if the terminal device has uplink data to be transmitted, and the amount of data sent by the terminal device supported by energy is greater than or equal to the data volume of the uplink data to be transmitted, the terminal device may respond to the first paging message. For another example, if the terminal device learns that there is downlink data to be transmitted on the network device side, and the amount of data received by the terminal device supported by energy is greater than or equal to the data volume of the downlink data to be transmitted, the terminal device may respond to the first paging message.

[0146] In some other implementations, the second information is used to indicate the energy of the terminal device and the amount of data to be transmitted. The terminal device determines whether to respond to the first paging message based on the energy of the terminal device and the amount of data to be transmitted. It can be understood that if the amount of data supported by the energy of the terminal device to be transmitted is less than the amount of data to be transmitted, the terminal device may not respond to the first paging message. For example, see Fig.10 , when the energy accumulated by the terminal device 1 is sufficient to receive the message, the terminal device 1 receives the first paging message. If the amount of data supported by the energy accumulated by the terminal device 1 is less than the amount of data to be transmitted, the terminal device 1 may not respond to the first paging message (for example, not establishing a connection with the network device). For another example, the terminal device has uplink data to be transmitted, and the amount of data supported by the energy accumulated by the terminal device is less than the amount of data for transmitting the uplink data to be transmitted, the terminal device may not respond to the first paging message. For another example, the terminal device learns that there is downlink data to be transmitted on the network device side, and the amount of data supported by the energy of the terminal device for receiving is less than the amount of data for transmitting the downlink data to be transmitted, the terminal device may not respond to the first paging message.

[0147] In some implementations, the second information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. The terminal device determines whether to respond to the first paging message based on the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. It can be understood that under the current energy of the terminal device and the current wireless signal quality, if the amount of data supported by the terminal device to be transmitted is greater than or equal to the amount of data to be transmitted, the terminal device can respond to the first paging message. For example, see Fig.10 , when the energy accumulated by the terminal device 1 is sufficient to receive the message, the terminal device 1 receives the first paging message. If, under the accumulated energy of the terminal device 1 and the current wireless signal quality, the amount of data supported by the terminal device for transmission is greater than or equal to the amount of data to be transmitted, the terminal device 1 can respond to the first paging message (for example, establish a connection with the network device). For another example, the terminal device has uplink data to be transmitted, and under the accumulated energy of the terminal device and the current wireless signal quality, the amount of data supported by the terminal device for sending is greater than or equal to the amount of uplink data to be transmitted, and the terminal device can respond to the first paging message. For another example, the terminal device learns that there is downlink data to be transmitted on the network device side, and under the accumulated energy of the terminal device and the current wireless signal quality, the amount of data supported by the terminal device for receiving is greater than or equal to the amount of downlink data to be transmitted, and the terminal device can respond to the first paging message.

[0148] In some implementations, the second information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. The terminal device determines whether to respond to the first paging message based on the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. It can be understood that under the current energy of the terminal device and the current wireless signal quality, if the amount of data supported by the terminal device for transmission is less than the amount of data to be transmitted, the terminal device may not respond to the first paging message. For example, see Fig.10 , when the energy accumulated by the terminal device 1 is sufficient to receive the message, the terminal device 1 receives the first paging message. If, under the accumulated energy of the terminal device 1 and the current wireless signal quality, the amount of data supported by the terminal device for transmission is less than the amount of data to be transmitted, the terminal device 1 may not respond to the first paging message (for example, not establishing a connection with the network device). For another example, the terminal device has uplink data to be transmitted, and under the accumulated energy of the terminal device and the current wireless signal quality, the amount of data supported by the terminal device for sending is less than the amount of data of the uplink data to be transmitted, and the terminal device may not respond to the first paging message. For another example, the terminal device learns that there is downlink data to be transmitted on the network device side, and under the accumulated energy of the terminal device and the current wireless signal quality, the amount of data supported by the terminal device for receiving is less than the amount of data of the downlink data to be transmitted, and the terminal device may not respond to the first paging message.

[0149] In some implementations, if the terminal device determines to respond to the first paging message, the terminal device sends response information to the first paging message to the network device, and the transmission of the response information is determined based on the energy of the terminal device.

[0150] In some implementations, the transmission of the response information is determined based on the energy of the terminal device, which can be understood as the terminal device determining whether to respond to the first paging message and the manner of responding to the first paging message based on the energy of the terminal device, and then determining the transmission of the response information based on the manner of responding to the first paging message. For example, the first paging message carries a dedicated identifier of the terminal device, and the energy of the terminal device supports response inventory. The terminal device determines that the manner of responding to the first paging message and the manner of responding to the first paging message is to initiate random access, and then determines that the manner of transmitting the response information is to send a message initiating random access to the network device (for example, message 1 (Msg1)). For another example, the first paging message does not carry a dedicated identifier of the terminal device, but includes an identifier of the paging group to which the terminal device belongs, and the energy of the terminal device supports response inventory and establishing a connection with the network device. The terminal device determines that the manner of responding to the first paging message and the manner of responding to the first paging message is to establish a connection with the network device, and then determines that the manner of transmitting the response information is to send a message to the network device to establish a connection with the network device (for example, a message to establish a radio resource control (RRC) connection).

[0151] In order to further avoid waste of resources and energy, in some implementations, if the terminal device responds to the first paging message, the terminal device determines whether to establish a connection with the network device based on the third information.

[0152] The following describes, in conjunction with Example 2, a solution for a terminal device to determine whether to establish a connection with a network device based on third information.

[0153] Embodiment 2: The terminal device determines whether to establish a connection with the network device based on the third information

[0154] In some implementations, the third information includes one or more of the following: energy of the terminal device; whether the data to be transmitted includes target data; and whether the terminal device supports the completion of transmission of the data to be transmitted.

[0155] In some implementations, the data to be transmitted includes target data, that is, the terminal device has downlink urgent data to receive.

[0156] In some implementations, the target data may be indicated by the first paging message. For example, the first paging message indicates to the terminal device the target data to be transmitted and the data volume of the target data.

[0157] In some implementations, establishing a connection with a network device may be understood as establishing an RRC connection.

[0158] In some implementations, whether the terminal device supports the completion of the transmission of the data to be transmitted can be understood as whether the terminal device supports the completion of the transmission of the uplink data and / or downlink data to be transmitted. In some implementations, whether the terminal device supports the completion of the transmission of the data to be transmitted is determined based on one or more of the following: the energy of the terminal device, the wireless signal quality of the terminal device, the amount of data to be transmitted, and the cache capacity of the terminal device.

[0159] It should be noted that the above descriptions about the energy of the terminal device, the wireless signal quality of the terminal device and the amount of data to be transmitted are also applicable to this embodiment and will not be repeated here.

[0160] In some implementations, the cache capacity of the terminal device can be understood as the amount of data that can be stored in the cache of the terminal device.

[0161] In some implementations, whether the terminal device supports the completion of the transmission of the data to be transmitted is determined based on the energy of the terminal device and the amount of the data to be transmitted. Therefore, whether the terminal device supports the completion of the transmission of the data to be transmitted can be understood as whether the energy of the terminal device supports the completion of the transmission of the data to be transmitted.

[0162] In some implementations, whether a terminal device supports the completion of transmission of data to be transmitted is determined based on the cache capacity of the terminal device and the amount of data to be transmitted. Therefore, whether a terminal device supports the completion of transmission of data to be transmitted can be understood as whether the cache of the terminal device supports the completion of transmission of data to be transmitted.

[0163] In some implementations, whether the terminal device supports the completion of the transmission of the data to be transmitted is determined based on the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. Therefore, whether the terminal device supports the completion of the transmission of the data to be transmitted can be understood as whether the current energy of the terminal device and the current wireless signal quality support the transmission of the entire amount of data to be transmitted.

[0164] Implementation method 2-1: If the data to be transmitted includes target data, the terminal device determines whether to establish a connection with the network device based on the energy of the terminal device.

[0165] In some implementations, the terminal device determines whether to establish a connection with the network device based on the energy of the terminal device. It can be understood that if the energy of the terminal device supports the transmission of target data, the terminal device determines to establish a connection with the network device; if the energy of the terminal device does not support the transmission of target data, the terminal device determines not to establish a connection with the network device.

[0166] In some implementations, if the data to be transmitted includes target data, and the terminal device determines to establish a connection with the network device, the terminal device gives priority to transmitting the target data. Accordingly, the terminal device may first transmit the target data, and then transmit the non-target data in the data to be transmitted within the energy range allowed by the terminal device. For example, the data to be transmitted includes target data and other uplink data to be transmitted, and the terminal device may give priority to transmitting the target data after establishing a connection with the network device. If the energy of the terminal device supports the transmission of all or part of the other uplink data to be transmitted, the terminal device may transmit all or part of the other uplink data to be transmitted; if the energy of the terminal device does not support the transmission of other uplink data to be transmitted, the terminal device may not transmit other uplink data to be transmitted.

[0167] Implementation 2-2: If the data to be transmitted does not include the target data, the terminal device determines whether to establish a connection with the network device based on whether the terminal device supports the completion of the transmission of the data to be transmitted. For example, if the data to be transmitted does not include the target data, if the terminal device supports the completion of the transmission of the data to be transmitted, the terminal device determines to establish a connection with the network device; if the terminal device does not support the completion of the transmission of the data to be transmitted, the terminal device determines not to establish a connection with the network device.

[0168] Implementation method 2-3: If the data to be transmitted does not include the target data, and the terminal device supports completing the transmission of the data to be transmitted, the terminal device determines whether to establish a connection with the network device based on whether there is a first reason.

[0169] In some implementations, the first reason is referred to as "other reasons why connection cannot be established."

[0170] In some implementations, the terminal device determines whether to establish a connection with the network device based on whether there is a first reason. It can be understood that if there is a first reason, the terminal device determines not to establish a connection with the network device; if there is no first reason, the terminal device determines to establish a connection with the network device.

[0171] In some implementations, the first reason is used to indicate that the terminal device determines that uplink data is about to arrive, and the terminal device hopes to complete the transmission of the to-be-transmitted data and the new uplink data at one time.

[0172] In other implementations, the first reason is used to instruct the terminal device to determine that the quality of the wireless signal is about to deteriorate, and once it deteriorates, it is impossible for the terminal device to complete the transmission of the data to be transmitted.

[0173] Implementation method 2-4: If the terminal device does not support the completion of the transmission of the data to be transmitted, the terminal device determines whether to establish a connection with the network device based on whether the data to be transmitted includes uplink emergency data or target data.

[0174] In some implementations, uplink urgent data may be understood as uplink data to be transmitted that is about to time out.

[0175] In some implementations, the terminal device determines whether to establish a connection with the network device based on whether the data to be transmitted includes uplink emergency data or target data. It can be understood that if the data to be transmitted includes uplink emergency data or target data, the terminal device determines to establish a connection with the network device; if the data to be transmitted does not include uplink emergency data or target data, the terminal device determines by itself whether to establish a connection with the network device.

[0176] In some implementations, if the data to be transmitted does not include target data and the terminal device does not support completing the transmission of the data to be transmitted, the terminal device determines whether to establish a connection with the network device based on whether the data to be transmitted includes uplink emergency data.

[0177] In some implementations, if the terminal device determines to establish a connection with the network device and completes the transmission of the data to be transmitted within the first paging window, the terminal device may no longer monitor the first paging message. Fig.10 , within the first paging window, the terminal device receives the first paging message, determines to respond to the first paging message, and determines to establish a connection with the network device. Then the terminal device establishes a connection with the network device within the first paging window and completes the transmission of the data to be transmitted. At this time, still within the first paging window, the terminal device can no longer monitor the first paging message, and can even shut down.

[0178] The above describes multiple solutions for a terminal device to determine whether to establish a connection with a network device based on third information in conjunction with Embodiment 2. In some scenarios, the above multiple solutions can be used alone. In other scenarios, the above multiple solutions can be used in combination with each other.

[0179] For ease of understanding, the following Fig.11 An example is given of combining the various solutions in Embodiment 2. Fig.11 Includes steps S1101 to S1111.

[0180] Assume that the terminal device determines to respond to the first paging message, and the first paging message indicates the downlink data to be transmitted and whether the data to be transmitted includes the target data.

[0181] In step S1101, the terminal device determines to respond to the first paging message.

[0182] If the terminal device determines to respond to the first paging message, the terminal device can determine whether to establish a connection with the network device based on the third information. The third information includes the following three types: the energy of the terminal device; whether the data to be transmitted includes the target data; whether the terminal device supports the completion of the transmission of the data to be transmitted. The terminal device first determines whether the data to be transmitted includes the target data and proceeds to step S1102.

[0183] In step S1102, the terminal device determines whether the data to be transmitted includes target data.

[0184] The terminal device determines whether the data to be transmitted includes the target data based on the information indicated by the first paging message. If the data to be transmitted includes the target data, the process proceeds to step S1103; if the data to be transmitted does not include the target data, the process proceeds to step S1104.

[0185] In step S1103 , the terminal device determines whether to establish a connection based on the energy of the terminal device.

[0186] The terminal device determines whether the energy of the terminal device supports the transmission of the target data based on the energy of the terminal device. If the energy of the terminal device supports the transmission of the target data, the process proceeds to step S1109; if the energy of the terminal device does not support the transmission of the target data, the process proceeds to step S1108.

[0187] In step S1104, the terminal device determines whether the terminal device supports completing the transmission of the data to be transmitted.

[0188] The terminal device determines whether the terminal device supports the completion of the transmission of the data to be transmitted based on the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of data to be transmitted. If the terminal device supports the completion of the transmission of the data to be transmitted, the process proceeds to step S1105; if the terminal device does not support the completion of the transmission of the data to be transmitted, the process proceeds to step S1109.

[0189] In step S1105, the terminal device determines whether there is a first cause.

[0190] The terminal device determines whether there is a first reason. If there is a first reason, it goes to step S1108; if there is no first reason, it goes to step S1109.

[0191] In step S1106, the terminal device determines whether the data to be transmitted includes uplink emergency data.

[0192] The terminal device determines whether the data to be transmitted includes uplink urgent data based on the uplink data to be transmitted. If the data to be transmitted includes uplink urgent data, the process proceeds to step S1109; if the data to be transmitted does not include uplink urgent data, the process proceeds to step S1107.

[0193] In step S1107, the terminal device determines on its own whether to establish a connection.

[0194] The terminal device determines on its own whether to establish a connection with the network device.

[0195] In step S1108, the terminal device does not establish a connection.

[0196] The terminal device does not establish a connection with the network device.

[0197] In step S1109, the terminal device establishes a connection.

[0198] The terminal device establishes a connection with the network device.

[0199] In step S1110, the terminal device receives target data or sends uplink emergency data.

[0200] After the terminal device establishes a connection with the network device, it gives priority to transmitting the target data, that is, receiving the target data. If the non-target data in the data to be transmitted includes uplink urgent data, the terminal device gives priority to transmitting the uplink urgent data.

[0201] In step S1111, the terminal device transmits other data.

[0202] The terminal device transmits other data in the data to be transmitted except the target data and / or uplink emergency data.

[0203] From the above, it can be seen that in a communication system, a terminal device (e.g., an AIoT device) can perform a sending or receiving operation only after collecting a certain amount of energy. Conversely, when the terminal device does not collect enough energy, the terminal device cannot perform a sending or receiving operation. However, in the transmission process of traditional paging messages, the network device does not perceive the energy of the terminal device, which may lead to a waste of resources or energy.

[0204] Taking the terminal device as an AIoT device as an example, the data transmission of the wireless interface requires two types of resources: energy resources and wireless resources. The energy resources are only known by the AIoT device, and the wireless resources are allocated by the network device. However, when the two resources do not match, the data transmission may not be completed, wasting wireless resources or wasting the energy of the AIoT device. For example, the network device sends a first paging message to the AIoT device and allocates downlink resources to the AIoT device. The energy of the AIoT device can support the reception of the first paging message, but does not support the reception of downlink data. Therefore, the reception of downlink data cannot be completed, resulting in a waste of wireless resources.

[0205] In response to the above problems, an embodiment of the present application provides a method for wireless communication, wherein a terminal device sends a first information to a network device, and the first information is used by the network device to allocate uplink and downlink resources and / or adjust the transmission of a paging message for paging the terminal device, which helps to increase the probability of completing data transmission and helps to improve the utilization of resources and energy.

[0206] In some implementations, the network device receives first information sent by the terminal device, and the network device may allocate uplink and downlink resources to the terminal device based on the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0207] In the embodiments of the present application, the method for adjusting the transmission of the paging message for the paging terminal device is not limited. In some implementations, adjusting the transmission of the paging message for the paging terminal device can be understood as adjusting the transmission time of the paging message for the paging terminal device. For example, delaying or advancing the transmission time of the paging message for the paging terminal device. In other implementations, adjusting the transmission of the paging message for the paging terminal device can be understood as adjusting the number of paging messages for the paging terminal device. For example, reducing or increasing the number of paging messages for the paging terminal device.

[0208] The following describes the related scheme of the first information in conjunction with Example 3.

[0209] Embodiment 3: First information

[0210] Implementation method 3-1: The first information is used to indicate one or more of the following: the energy of the terminal device; the wireless signal quality of the terminal device; the amount of uplink data that can be transmitted supported by the energy of the terminal device and / or the wireless signal quality of the terminal device; the amount of downlink data that can be transmitted supported by the energy of the terminal device and / or the wireless signal quality of the terminal device; whether the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the amount of uplink data to be transmitted; whether the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the amount of downlink data to be transmitted; the energy collection speed of the terminal device.

[0211] It should be noted that the above description about the energy of the terminal device and the wireless signal quality of the terminal device is also applicable to this embodiment and will not be repeated here.

[0212] In some implementations, the amount of uplink data supported for transmission by the energy of the terminal device and / or the wireless signal quality of the terminal device may be understood as the amount of uplink data supported for transmission by the terminal device under the current energy of the terminal device and / or the wireless signal quality of the terminal device.

[0213] In some implementations, the amount of downlink data that the terminal device's energy and / or the terminal device's wireless signal quality supports for transmission can be understood as the amount of downlink data that the terminal device supports for transmission under the terminal device's current energy and / or the terminal device's wireless signal quality.

[0214] In some implementations, whether the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the uplink data volume to be transmitted can be understood as whether the terminal device supports the transmission of all uplink data volume to be transmitted under the current energy of the terminal device and / or the wireless signal quality of the terminal device.

[0215] In some implementations, whether the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the downlink data volume to be transmitted can be understood as whether the terminal device supports the transmission of all downlink data volume to be transmitted under the current energy of the terminal device and / or the wireless signal quality of the terminal device.

[0216] In some implementations, the speed of energy collection by the terminal device can be understood as the speed of energy collection by the terminal device under the current circumstances. For example, the energy collected by the terminal device every 10 minutes can support the reception of XX bytes of downlink data and / or support the sending of YY bytes of uplink data.

[0217] In some implementations, the first information is used to indicate the energy of the terminal device. Accordingly, when the network device receives the first information, it can allocate uplink and downlink resources to the terminal device based on the energy of the terminal device indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device. For example, the network device knows that the energy of the terminal device supports the ability to transmit uplink and downlink data, and based on the current energy of the terminal device, it can determine whether the terminal device supports the transmission of downlink data to be transmitted, and further determine whether to allocate downlink resources to the terminal device and / or adjust the transmission of a paging message for paging the terminal device.

[0218] In some implementations, the first information is used to indicate the energy of the terminal device and the wireless signal quality of the terminal device. Accordingly, when the network device receives the first information, it can allocate uplink and downlink resources to the terminal device based on the energy of the terminal device and the wireless signal quality of the terminal device indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device. For example, the network device knows that the energy of the terminal device supports the ability to transmit downlink data. Based on the current energy of the terminal device and the current wireless signal quality, it can determine whether the current energy of the terminal device and the wireless signal quality of the terminal device support the transmission of the downlink data to be transmitted, and further determine whether to allocate downlink resources to the terminal device and / or adjust the transmission of a paging message for paging the terminal device.

[0219] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of uplink data that the energy of the terminal device and / or the wireless signal quality of the terminal device support for transmission. Accordingly, the network device receives the first information and can allocate uplink resources based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0220] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of downlink data that the energy of the terminal device and / or the wireless signal quality of the terminal device support for transmission. Accordingly, the network device receives the first information and can allocate downlink resources based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0221] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and whether the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the amount of uplink data to be transmitted. Accordingly, the network device receives the first information and may allocate or not allocate uplink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0222] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of uplink data to be transmitted that the energy of the terminal device and / or the wireless signal quality of the terminal device support. Accordingly, the network device receives the first information and can allocate uplink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0223] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the amount of uplink data to be transmitted. Accordingly, the network device receives the first information and may not allocate uplink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0224] In some implementations, the first information is used to indicate the energy of the terminal device, the quality of the wireless signal of the terminal device, and whether the energy of the terminal device and / or the quality of the wireless signal of the terminal device support the transmission of the amount of downlink data to be transmitted. Accordingly, the network device receives the first information and may allocate or not allocate downlink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0225] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the amount of downlink data to be transmitted that the energy of the terminal device and / or the wireless signal quality of the terminal device support. Accordingly, the network device receives the first information and can allocate downlink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0226] In some implementations, the first information is used to indicate the energy of the terminal device, the wireless signal quality of the terminal device, and the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the amount of downlink data to be transmitted. Accordingly, the network device receives the first information and may not allocate uplink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of a paging message for paging the terminal device.

[0227] In some implementations, the amount of downlink data to be transmitted supported by the energy of the terminal device and / or the wireless signal quality of the terminal device indicated by the first information may be determined based on the amount of downlink data to be transmitted indicated by the first paging message. For example, the first paging message indicates the amount of downlink data to be transmitted, and the terminal device determines part or all of the amount of downlink data to be transmitted supported by the terminal device based on the energy of the terminal device and / or the wireless signal quality of the terminal device.

[0228] In some implementations, the first information indicates the energy of the terminal device and the energy collection speed of the terminal device. Accordingly, when the network device receives the first information, it can allocate uplink and downlink resources to the terminal device based on the content indicated by the first information, and / or adjust the transmission of the paging message used to paging the terminal device. For example, the network device knows the ability of the terminal device's energy to support the transmission of downlink data. Based on the current energy of the terminal device, it can be determined that the terminal device does not support the transmission of the downlink data to be transmitted. Based on the energy collection speed of the terminal device, the network device determines that the terminal device's energy after 10 minutes supports the transmission of the downlink data to be transmitted. Therefore, the network device allocates downlink resources to the terminal device after 10 minutes, and postpones the transmission time of the paging message used to paging the terminal device (such as sending a paging message after 10 minutes).

[0229] In some implementations, the first information is carried by one or more of the following: a medium access control control element (MAC CE) message, an RRC message, and a physical uplink control channel (PUCCH).

[0230] In some implementations, the first information is carried in a message in a random access process. For example, the terminal device sends the first information to the terminal device via message 3 (Msg3) in the random access process.

[0231] In some implementations, the first information is carried in UE assistance information (UE assistance information, UAI). For example, the terminal device reports the first information to the network device through the UAI.

[0232] In some implementations, when the first condition is met, the terminal device sends updated first information to the network device.

[0233] In some implementations, the updated first information can be understood as the content indicated by the first information changes, and the updated first information indicates the updated content. For example, the first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the amount of downlink data to be transmitted. After the terminal device sends the first information for the first time, the wireless signal quality of the terminal device changes significantly, resulting in a change in the amount of downlink data to be transmitted that supports transmission. The terminal device sends the updated first information, and the updated first information indicates the updated amount of downlink data to be transmitted that supports transmission. For another example, the first information indicates whether the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the amount of uplink data to be transmitted. After the terminal device sends the first information for the first time, a large amount of uplink data arrives at the access layer of the terminal device, resulting in the previously reported first information being no longer accurate, which may cause the terminal device to change from supporting the transmission of the amount of uplink data to be transmitted to no longer supporting the transmission of the amount of uplink data to be transmitted. The terminal device can send the updated first information, and the updated first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the amount of uplink data to be transmitted.

[0234] In some implementations, the first condition includes one or more of the following: the difference between the wireless signal quality of the terminal device indicated by the first information and the wireless signal quality of the terminal device indicated by the updated first information is greater than a first threshold; the information in the first information indicating that the terminal device can complete the transmission of the data to be transmitted is invalid; the amount of uplink data arriving at the access layer of the terminal device after sending the first information exceeds a second threshold.

[0235] In some implementations, the first condition includes that the difference between the wireless signal quality of the terminal device indicated by the first information and the wireless signal quality of the terminal device indicated by the updated first information is greater than a first threshold, that is, if the difference between the wireless signal quality of the terminal device indicated by the first information and the wireless signal quality of the terminal device indicated by the updated first information is greater than the first threshold, the terminal device sends the updated first information. For example, the first information is used to indicate the wireless signal quality of the terminal device. When the terminal device sends the first information for the first time, the wireless signal quality of the terminal device is RSRP1, and the first threshold is Δ. If the subsequent wireless signal quality of the terminal device exceeds the range of RSRP1±Δ, the terminal device sends the updated first information.

[0236] In some implementations, the first condition includes the failure of information in the first information indicating that the terminal device can complete the transmission of the data to be transmitted, that is, if the information in the first information indicating that the terminal device can complete the transmission of the data to be transmitted fails, the terminal device sends the updated first information. For example, the first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the amount of uplink data to be transmitted. After the terminal device sends the first information for the first time, due to the deterioration of the wireless signal quality, the information in the previously sent first information indicating that the terminal device can complete the transmission of the data to be transmitted fails, that is, the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the amount of uplink data to be transmitted. When the first condition is met, the terminal device sends the updated first information, and the updated first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the amount of uplink data to be transmitted. For another example, the first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the uplink data volume to be transmitted. After the terminal device sends the first information for the first time, the wireless signal quality improves, resulting in the failure of the information in the first information indicating that the terminal device can complete the transmission of the data to be transmitted, that is, the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the uplink data volume to be transmitted, and the first condition is met, and the terminal device sends the updated first information, and the updated first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the uplink data volume to be transmitted. For another example, the first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device support the transmission of the uplink data volume to be transmitted. After the terminal device sends the first information for the first time, new uplink data arrives at the access layer of the terminal device, resulting in the failure of the information in the first information indicating that the terminal device can complete the transmission of the data to be transmitted, that is, the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the uplink data volume to be transmitted, and the first condition is met, and the terminal device sends the updated first information, and the updated first information indicates that the energy of the terminal device and / or the wireless signal quality of the terminal device do not support the transmission of the uplink data volume to be transmitted.

[0237] In some implementations, the first condition includes that the amount of uplink data arriving at the access layer of the terminal device after the first information is sent exceeds a second threshold, that is, after the terminal device sends the first information for the first time, the amount of uplink data arriving at the access layer of the terminal device exceeds the second threshold, and the terminal device sends the updated first information. For example, the first information is used to indicate whether the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the amount of uplink data to be transmitted, and the second threshold is θ. After the terminal device sends the first information for the first time, the amount of uplink data arriving at the access layer of the terminal device exceeds θ, then the terminal device sends the updated first information, and the updated first information indicates whether the energy of the terminal device and / or the wireless signal quality of the terminal device supports the transmission of the amount of uplink data to be transmitted (the sum of the amount of uplink data to be transmitted when the first information is sent and the amount of uplink data arriving at the access layer of the terminal device thereafter).

[0238] In some implementations, the first threshold and / or the second threshold may be specified by a protocol.

[0239] In some other implementations, the first threshold and / or the second threshold may be configured by the network device. For example, the base station indicates the first threshold and / or the second threshold to the network device through the SIB.

[0240] Implementation 3-2: The first information is used to indicate one or more of the following: the terminal device has received the first paging message; the energy of the terminal device is insufficient to complete uplink data transmission; the energy of the terminal device is insufficient to complete downlink data transmission; the first data has not arrived at the terminal device, and the first data is transmitted together with the data to be transmitted that has arrived at the terminal device; the second data has not arrived at the network device, and the second data is transmitted together with the data to be transmitted that has arrived at the network device; the time when the terminal device is ready to establish a connection with the network device. The terminal device indicates the first information to the network device, which helps to avoid the network device from continuing to send the first paging message, so as to reduce the waste of downlink wireless resources and the power consumption of the network device.

[0241] In the embodiment of the present application, the indication method of the time when the terminal device is ready to establish a connection with the network device is not limited. For example, an absolute time may be used to indicate the time when the terminal device is ready to establish a connection with the network device. For another example, one or more of the following may be used to indicate the time when the terminal device is ready to establish a connection with the network device: system frame number (SFN), subframe, time slot, symbol position.

[0242] In some implementations, the first information is used to indicate that the terminal device has received the first paging message and that the energy of the terminal device is unable to complete the downlink data transmission. This can be understood as the terminal device having received the first paging message, but being unable to complete the transmission of the downlink data to be transmitted under the current energy and / or wireless signal quality of the terminal device, so a connection with the network device is temporarily not established.

[0243] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, that the energy of the terminal device is insufficient to complete downlink data transmission, and the time when the terminal device is ready to establish a connection with the network device. For example, the terminal device does not establish a connection with the network device temporarily, and is ready to establish a connection with the network device after time T1.

[0244] In some implementations, the first information is used to indicate that the terminal device has received the first paging message and that the energy of the terminal device is unable to complete the uplink data transmission. This can be understood as the terminal device having received the first paging message, but being unable to complete the transmission of the uplink data to be transmitted under the current energy and / or wireless signal quality of the terminal device, and therefore temporarily not establishing a connection with the network device.

[0245] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, that the energy of the terminal device is insufficient to complete uplink data transmission, and the time when the terminal device is ready to establish a connection with the network device. For example, the terminal device does not establish a connection with the network device temporarily, and is ready to establish a connection with the network device after time T2.

[0246] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, the energy of the terminal device is unable to complete downlink data transmission, and the energy of the terminal device is unable to complete uplink data transmission. It can be understood that the terminal device has received the first paging message, but under the current energy and / or wireless signal quality of the terminal device, the transmission of the uplink data and downlink data to be transmitted cannot be completed, so the connection with the network device is temporarily not established.

[0247] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, that the energy of the terminal device is insufficient to complete downlink data transmission, that the energy of the terminal device is insufficient to complete uplink data transmission, and the time at which the terminal device is ready to establish a connection with the network device. For example, the terminal device does not establish a connection with the network device temporarily, and is ready to establish a connection with the network device after time T3.

[0248] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, and the first data has not arrived at the terminal device, and the first data is transmitted together with the data to be transmitted that has arrived at the terminal device. It can be understood that the terminal device has received the first paging message, and the terminal device can complete the transmission of the uplink data to be transmitted under the current energy and / or wireless signal quality of the terminal device, but the first data will arrive at the terminal device in the future, so the connection with the network device is not established temporarily, and the connection with the network device is established after the first data arrives at the terminal device, and the first data is transmitted together with the data to be transmitted that has arrived at the terminal device.

[0249] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, the first data has not arrived at the terminal device, the first data is transmitted together with the data to be transmitted that has arrived at the terminal device, and the time when the terminal device is ready to establish a connection with the network device. For example, the terminal device does not establish a connection with the network device temporarily, and is ready to establish a connection with the network device after time T4. Time T4 can be within the first paging window or outside the first paging window. Accordingly, the network device configures the uplink resources at time T4 for the terminal device based on the first information, and adjusts the transmission of the paging message used to paging the terminal device (for example, the network device does not need to send the first paging message again).

[0250] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, and the second data has not arrived at the network device, and the second data is transmitted together with the data to be transmitted that has arrived at the network device. It can be understood that the terminal device has received the first paging message, and the terminal device can complete the transmission of the downlink data to be transmitted under the current energy and / or wireless signal quality, but the second data will arrive at the network device in the future, so the connection with the network device is not established temporarily, and the connection with the network device is established after the second data arrives at the network device, and the second data is transmitted together with the data to be transmitted that has arrived at the network device.

[0251] In some implementations, the first information is used to indicate that the terminal device has received the first paging message, the second data has not arrived at the network device, the second data is transmitted together with the data to be transmitted that has arrived at the network device, and the time when the terminal device is ready to establish a connection with the network device. For example, the terminal device does not establish a connection with the network device temporarily, and is ready to establish a connection with the network device after time T5. Time T5 can be within the first paging window or outside the first paging window. Accordingly, the network device configures the downlink resources at time T5 for the terminal device based on the first information, and adjusts the transmission of the paging message used to paging the terminal device (for example, the network device does not need to send the first paging message again).

[0252] In some implementations, the terminal device may determine whether there is the second data through auxiliary information indicated by an application layer of the terminal device.

[0253] In some implementations, if the first information is used to indicate that the first data and / or the second data are transmitted together with the data to be transmitted, and the first information is also used to indicate the time when the terminal device is ready to establish a connection with the network device, the terminal device can actively establish a connection with the network device. Accordingly, the network device can determine that it is not necessary to send a paging message for paging the terminal device again based on the first information.

[0254] In some implementations, the terminal device may send the first information to the network device via the uplink resources indicated by the first paging information.

[0255] The above text, in combination with Example 1, Example 2, and Example 3, respectively introduces the schemes for implementing the method in which the terminal device determines whether to respond to the first paging message, the terminal device determines whether to establish a connection, and the first information sent by the terminal device. In some implementations, Example 1, Example 2, and Example 3 can be used alone. In other scenarios, Example 1, Example 2, and Example 3 can be used in combination with each other. The following text introduces the scheme in which Example 1, Example 2, and Example 3 are combined with each other.

[0256] In some implementations, the terminal device determines to respond to the first paging message based on the solution of Example 1, and determines to establish a connection with the network device based on the solution of Example 2, then the terminal device can determine that the implementation of the first information is implementation 3-1. For example, the terminal device determines to respond to the first paging message, determines to establish a connection with the network device based on the third information, and sends the first information to the network device, the first information is used to indicate the amount of downlink data that the energy of the terminal device and / or the wireless signal quality of the terminal device supports for transmission, and the network device receives the first information, and can determine the amount of downlink data that the terminal device can support for reception based on the first information, and allocate corresponding downlink resources for it.

[0257] In some implementations, if the terminal device determines to establish a connection with the network device based on the solution of Example 2, the terminal device may determine that the implementation of the first information is implementation 3-1. For example, if the terminal device determines to establish a connection with the network device based on the third information, the terminal device sends the first information to the network device, and the first information is used to indicate the amount of downlink data that the energy of the terminal device and / or the wireless signal quality of the terminal device supports for transmission. The network device receives the first information and may determine the amount of downlink data that the terminal device can support for reception based on the first information, and allocate corresponding downlink resources to it.

[0258] In some implementations, the terminal device determines to respond to the first paging message based on the solution of Example 1, and determines not to establish a connection with the network device based on the solution of Example 2, then the terminal device may determine that the implementation of the first information is implementation 3-2. For example, the terminal device determines to respond to the first paging message, determines not to establish a connection with the network device based on the third information, and sends the first information to the network device, the first information is used to indicate that the energy of the terminal device cannot complete the downlink data transmission, the network device receives the first information, and can determine based on the first information that the terminal device does not support receiving downlink data, so the terminal device does not temporarily allocate downlink resources to the terminal device, and postpones the transmission of the paging message used to paging the terminal device.

[0259] In some implementations, if the terminal device determines not to establish a connection with the network device based on the solution of Example 2, the terminal device may determine that the implementation of the first information is implementation 3-2. For example, if the terminal device determines not to establish a connection with the network device based on the third information, the terminal device sends the first information to the network device, and the first information is used to indicate the amount of downlink data that the energy of the terminal device and / or the wireless signal quality of the terminal device supports for transmission. The network device receives the first information and may determine the amount of downlink data that the terminal device can support for reception based on the first information, and allocate corresponding downlink resources to it.

[0260] As can be seen from the above, the network device can send a first paging message to the terminal device based on a paging group (hereinafter referred to as the "first paging group"). In some scenarios, the first paging group is invisible to the network device, and the network device will send the first paging message to multiple terminal devices included in the first paging group. How the terminal device determines whether the first paging message is used to page itself is a problem to be solved.

[0261] In order to solve the above problem, an embodiment of the present application provides a wireless communication method, wherein a first paging message is used to page a first paging group, and an upper layer of a terminal device and / or an access layer of the terminal device determines whether the first paging group includes the terminal device.

[0262] The following describes, in conjunction with Embodiment 4, a solution for an upper layer of a terminal device and / or an access layer of a terminal device to determine whether a first paging group includes a terminal device.

[0263] Embodiment 4: The upper layer of the terminal device and / or the access layer of the terminal device determines whether the first paging group includes the terminal device

[0264] In some implementations, the upper layer of the terminal device may be a non-access layer or an application layer of the terminal device, the access layer of the terminal device indicates information of the first paging group to the non-access layer or the application layer of the terminal device, and the non-access layer or the application layer of the terminal device determines whether the first paging group includes the terminal device based on the information of the first paging group.

[0265] In some implementations, the first paging message is used to page the first paging group, and the non-access layer or application layer of the terminal device can indicate to the access layer of the terminal device whether the first paging group includes the terminal device.

[0266] In some implementations, the non-access layer or application layer of the terminal device determines whether the first paging group includes the terminal device based on the information of the first paging group. It can be understood that if the non-access layer or application layer of the terminal device determines that the paging group to which it belongs includes the first paging group, then the first paging group includes the terminal device; if the non-access layer or application layer of the terminal device determines that the paging group to which it belongs does not include the first paging group, then the first paging group does not include the terminal device. For example, the paging group to which the terminal device belongs includes the first paging group and the second paging group. If the non-access layer or application layer of the terminal device determines that the paging group to which it belongs includes the first paging group, then the first paging group includes the terminal device.

[0267] In some implementations, a method for determining whether the first paging group includes the terminal device is to determine whether the ID of the paging group to which the terminal device belongs includes the ID of the first paging group. For example, if the ID of the first paging group is 100, the IDs of the paging groups to which the terminal device belongs are 100 and 101, and the ID of the paging group to which the terminal device belongs includes the ID of the first paging group, then the first paging group includes the terminal device.

[0268] In some other implementations, the first paging message is used to page a first paging group, and the access layer of the terminal device determines whether the first paging group includes the terminal device based on the paging group to which the terminal device belongs.

[0269] In some implementations, the access layer of the terminal device determines whether the first paging group includes the terminal device based on the paging group to which the terminal device belongs. It can be understood that if the access layer of the terminal device determines that the paging group to which it belongs includes the first paging group, then the first paging group includes the terminal device; if the access layer of the terminal device determines that the paging group to which it belongs does not include the first paging group, then the first paging group does not include the terminal device.

[0270] In some implementations, the paging group to which the terminal device belongs is indicated by the non-access layer or application layer of the terminal device to the access layer of the terminal device. For example, the non-access layer or application layer of the terminal device indicates the ID of the paging group to which the terminal device belongs to the access layer of the terminal device.

[0271] For ease of understanding, the following Fig.12 An example is given to introduce a solution in which a terminal device determines whether a first paging group includes the terminal device.

[0272] See also Fig.12 , Fig.12Steps S1210 to S1214 are used to introduce a solution in which the non-access layer or application layer of the terminal device determines whether the first paging group includes the terminal device.

[0273] In step S1210, the AMF sends a first paging message to the base station.

[0274] The first paging message is used to page the first paging group, and the first paging message carries the ID of the first paging group.

[0275] In step S1211 , the base station sends a first paging message to terminal device 1 and terminal device 2 .

[0276] In step S1212 , the access layer of terminal device 2 sends the ID of the first paging group to the non-access layer of terminal device 2 .

[0277] In step S1213 , the non-access layer of terminal device 2 determines whether the first paging group includes terminal device 2 , and sends the result to the access layer of terminal device 2 .

[0278] The non-access layer of the terminal device 2 determines whether the first paging group includes the terminal device 2, such as by comparing whether the ID of the paging group to which the terminal device 2 belongs includes the ID of the first paging group. If the ID of the paging group to which the terminal device 2 belongs includes the ID of the first paging group, the first paging group includes the terminal device 2; otherwise, the first paging group does not include the terminal device 2.

[0279] In step S1214, the terminal device determines whether to respond to the first paging group.

[0280] If the first paging group includes terminal device 2, terminal device 2 can determine that the first paging message is used to paging terminal device 2, and terminal device 2 can continue to determine whether to respond to the first paging message based on the energy of terminal device 2; if the first paging group does not include terminal device 2, terminal device 2 can determine that the first paging message is not used to paging terminal device 2, and terminal device 2 can determine not to respond to the first paging message.

[0281] Continue to see Fig.12 , Fig.12 Steps S1220 to S12244 are used to introduce a scheme in which the access layer of the terminal device determines whether the first paging group includes the terminal device.

[0282] In step S1220 , the non-access layer of the terminal device 2 sends the ID of the paging group to which the terminal device 2 belongs to the access layer of the terminal device 2 .

[0283] In step S1221, the access layer of the terminal device 2 stores the ID of the paging group to which the terminal device 2 belongs.

[0284] In step S1222, the AMF sends a first paging message to the base station.

[0285] The first paging message is used to page the first paging group, and the first paging message carries the ID of the first paging group.

[0286] In step S1223 , the base station sends a first paging message to terminal device 1 and terminal device 2 .

[0287] In step S1224, terminal device 2 determines whether the first paging group includes terminal device 2, and determines whether to respond to the first paging message.

[0288] The access layer of the terminal device 2 determines whether the first paging group includes the terminal device 2 based on the stored ID of the paging group to which the terminal device 2 belongs, such as by comparing whether the paging group ID to which the terminal device 2 belongs includes the first paging group ID. If the paging group ID to which the terminal device 2 belongs includes the first paging group, the first paging group includes the terminal device 2; otherwise, the first paging group does not include the terminal device 2. If the first paging group includes the terminal device 2, the terminal device 2 may determine that the first paging message is used to paging the terminal device 2, and the terminal device 2 may continue to determine whether to respond to the first paging message based on the energy of the terminal device 2; if the first paging group does not include the terminal device 2, the terminal device 2 may determine that the first paging message is not used to paging the terminal device 2, and the terminal device 2 may determine not to respond to the first paging message.

[0289] In some implementations, the terminal device belongs to the first paging group and the second paging group, the first paging message is used to page the first paging group, and the terminal device can send the data to be transmitted associated with the first paging group and / or the data to be transmitted associated with the second paging group to the network device. That is to say, the terminal device can establish a connection with the network device based on the first paging message, and send the data to be transmitted associated with the first paging group and / or the data to be transmitted associated with the second paging group to the network device to improve resource utilization.

[0290] In some implementations, if a terminal device establishes a connection with a network device based on a first paging message and sends to-be-transmitted data associated with a first paging group and / or to-be-transmitted data associated with a second paging group to the network device, the terminal device may not monitor the paging message used to paging the second paging group within a first time period to improve resource utilization.

[0291] In some implementations, if the terminal device establishes a connection with a network device based on a second paging message and sends to-be-transmitted data associated with a first paging group and / or to-be-transmitted data associated with a second paging group to the network device, the terminal device may not monitor the paging message used to paging the first paging group within a second time period to improve energy utilization.

[0292] In some implementations, the first time period and / or the second time period is configured by the network device.

[0293] In some implementations, the first time period and / or the second time period is configured by a core network device. For example, the core network device determines the length of the first time period to be T1, and notifies the terminal device through a non-access stratum (NAS) message, and the core network device ensures that after a paging based on a first paging group is initiated in a cell, a paging based on a second paging group will not be initiated in the same cell within the T1 time period. For another example, the core network device determines the length of the second time period to be T2, and notifies the terminal device through a NAS message, and the core network device ensures that after a paging based on a second paging group is initiated in a cell, a paging based on the first paging group will not be initiated in the same cell within the T2 time period.

[0294] In some other implementations, the first time period and / or the second time period is configured by the access network device. For example, the access network device is a base station, the base station determines that the first time period and / or the second time period are T1 and T2 respectively, the first paging message and / or the second paging message are sent by the core network to the base station, the base station does not send the first paging message and / or the second paging message over the air interface in the T1 / T2 time period, and the first paging message and / or the second paging message needs to be stored in the base station for a period of time.

[0295] The above describes various solutions that are helpful in solving multiple problems of the traditional paging mechanism in combination with Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4. In some implementations, Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 can be used alone. In other scenarios, Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 can be used in combination with each other.

[0296] From the above, it can be seen that in the traditional transmission process of paging messages, since the network device does not perceive the energy of the terminal device, there is a problem that resources or energy may be wasted.

[0297] To address this problem, an embodiment of the present application further provides a method for wireless communication, wherein the access layer of a terminal device indicates fourth information to an upper layer of the terminal device, and / or the access network device indicates fourth information to an application server or a core network element, and the fourth information is used to indicate the time for the energy collected by the terminal device to support the terminal device to perform wireless transmission, and / or the energy collected by the terminal device to support the terminal device to transmit a target amount of data. Based on the fourth information, it helps the upper layer of the terminal device and / or the application server or the core network element to generate data and allocate uplink and downlink resources in an appropriate time window to improve the utilization of resources and energy.

[0298] Embodiment 5: Method of indicating the fourth information

[0299] In some implementations, the upper layer of the terminal device may be a non-access layer or an application layer of the terminal device, and the access layer of the terminal device indicates fourth information to the non-access layer or the application layer of the terminal device, and the fourth information is used to indicate the time for the energy collected by the terminal device to support the terminal device to perform wireless transmission, and / or the energy collected by the terminal device to support the terminal device to transmit a target amount of data. The access layer of the terminal device indicates the fourth information to the upper layer, which helps the upper layer to generate uplink data in an appropriate time window, so as to reduce power consumption caused by the uplink data waiting in the cache.

[0300] In some implementations, the time during which the energy collected by the terminal device supports the terminal device to perform wireless transmission can be understood as the time during which the energy collected by the terminal device supports the terminal device to perform uplink and / or downlink data transmission.

[0301] In some implementations, the energy collected by the terminal device supports the terminal device to transmit a target amount of data. It can be understood that the energy collected by the terminal device supports the terminal device to transmit the target amount of uplink data and / or downlink data.

[0302] In some implementations, the target data volume is configured by the network device. For example, when the network device configures the target data volume as X Bytes, and the terminal device determines that its energy can support the transmission of X Bytes of uplink data, the access layer of the terminal device indicates fourth information to the non-access layer or application layer of the terminal device, and the fourth information indicates that the energy collected by the terminal device supports the terminal device to transmit X Bytes of uplink data.

[0303] In some implementations, the access network device indicates the fourth information to the application server or the core network element. Accordingly, the application server or the core network element obtains the fourth information and can determine the timing of sending the paging message for paging the terminal device based on the fourth information. For example, the core network element is a user plane function (UPF) element. If the energy of the terminal device does not support responding to the paging message, or does not support the transmission of downlink data for the terminal device in the UPF element, the paging message may not be sent temporarily.

[0304] In some implementations, the fourth information is determined by the access network device based on the energy collection speed of the terminal device. For example, the network device is an access network device, and the terminal device sends first information to the access network device, the first information indicates the energy collection speed of the terminal device, and the access network device determines the time for the energy collected by the terminal device to support the terminal device to perform wireless transmission based on the energy collection speed of the terminal device. For another example, the access network device determines that the energy collected by the terminal device supports the terminal device to transmit X Bytes of uplink data and / or Y Bytes of downlink data, and the time for the energy collected by the terminal device to support the terminal device to transmit X Bytes of uplink data and / or Y Bytes of downlink data based on the energy collection speed of the terminal device.

[0305] In some implementations, the time for indicating the fourth information may be indicated before the time when the energy collected by the terminal device supports the terminal device to perform wireless transmission.

[0306] In some other implementations, the time for indicating the fourth information may be indicated when the time when the energy collected by the terminal device supports the terminal device to perform wireless transmission is reached.

[0307] The above describes various solutions that are helpful to solve multiple problems of the traditional paging mechanism in combination with Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4 and Embodiment 5. In some implementations, Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4 and Embodiment 5 can be used alone. In other scenarios, Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4 and Embodiment 5 can be used in combination with each other.
