Description

Wireless communication method and communication device Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a wireless communication method and communication device. Background Art

[0002] In some scenarios, the second device can send a signal to the first device (for example, an ambient power (AMP) device) to provide energy and / or power to the first device so that the first device can communicate with the second device. However, the second device is usually far away from the first device. In this case, the second device is required to have a higher transmission power. For some reasons (for example, regulatory rules of various countries and regions, etc.), the maximum transmission power of the second device is limited, which may cause the first device to take a long time to collect energy and / or power based on the signal transmitted by the second device at the maximum transmission power. Even when the first device is far away from the second device, the signal transmitted by the second device at the maximum transmission power may not reach the first device, which greatly limits the distance between the second device and the first device.

[0003] In other scenarios, the second device can send a wake-up signal to the first device to wake up the first device from sleep mode and communicate with the second device. However, the second device is usually far away from the first device. In this case, the second device is required to have a higher transmission power so that the first device can receive the wake-up signal. However, for some reasons (for example, regulatory rules in various countries and regions), the maximum transmission power of the second device is limited, which greatly limits the distance between the second device and the first device.

For example, the 802.11 standard includes but is not limited to the 802.11ax standard, the 802.11be standard, and the next generation 802.11 standard.

[0044] FIG1 is a schematic diagram of a communication system applicable to an embodiment of the present application. Referring to FIG1 , the communication devices in the communication system 100 may include access points (APs) 211 and 212, and stations (STAs) 221 and 222.

[0048] In addition, the above communication system can be applied to scenarios of multi-device collaboration, such as multi-AP (multiple access points, Multi-AP) collaboration, or multi-site collaboration.

[0049] In the embodiments of this application, the names of AP and / or STA are not limited. In some scenarios, AP can also be called AP STA, that is, in a sense, AP is also a type of STA. In other scenarios, STA can also be called non-AP STA.

[0050] In the embodiments of the present application, an AP may be a device in a wireless network. An AP may be a communication entity such as a communication server, a router, a switch, or a bridge, or the AP device may include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP may also be a chip, circuit, or processing system in these various forms of devices, thereby realizing the methods and functions of the embodiments of the present application. The AP device can be applied to a variety of scenarios, such as sensor nodes in smart cities (e.g., smart water meters, smart electricity meters, smart air detection nodes), smart devices in smart homes (e.g., smart cameras, projectors, displays, televisions, speakers, refrigerators, washing machines, etc.), nodes in the Internet of Things, entertainment terminals (e.g., wearable devices such as AR and VR), smart devices in smart offices (e.g., printers, projectors, etc.), Internet of Vehicles devices in the Internet of Vehicles, and some infrastructure in daily life scenarios (e.g., vending machines, self-service navigation counters in supermarkets, self-service checkout devices, self-service ordering machines), etc.

[0051] In some implementations, the role of a STA in a communication system is not absolute; in some scenarios, a STA can function as an AP. For example, when a mobile phone is connected to a router, it can be a non-AP STA, while when it is acting as a hotspot for other phones, it functions as an AP.

[0052] In the embodiments of the present application, a STA device in the embodiments of the present application may be a device with wireless transceiver functions, such as a device that supports the 802.11 series of protocols and can communicate with an AP or other STAs. For example, a STA is any user communication device that allows a user to communicate with an AP and, in turn, with a WLAN. STA devices include, for example, user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device.

The terminal equipment in the network (PLMN), etc., is not limited to this in the embodiments of the present application.

[0054] By way of example and not limitation, in the embodiments of this application, the STA device may also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for wearable devices that utilize wearable technology to intelligently design and develop wearable devices, such as glasses, gloves, watches, clothing, and shoes. Examples include smart watches or smart glasses, as well as devices that focus on a specific application function and require integration with other devices, such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0055] In addition, in embodiments of the present application, the STA device can also be a terminal device in the Internet of Things (IoT) system. The IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network that interconnects people and machines and things. In embodiments of the present application, IoT technology can achieve massive connections, deep coverage, and terminal power saving through, for example, narrowband (NB) technology.

[0056] Furthermore, in the embodiments of the present application, the STA device may be a device in a connected vehicle system.

For example, V2X communication includes vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-network (V2N) communication.

[0058] In addition, the AP device in the embodiment of the present application may be a device for communicating with a STA device. The AP device may be a network device in a wireless local area network. The AP device may be used to communicate with the STA device through the wireless local area network.

[0059] From the perspective of the communication standards supported by the AP, in some implementations, the AP can be a device that supports the 802.11be standard. The AP can also be a device that supports various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0060] From the perspective of STA-supported communication standards, in some implementations, non-AP STAs can support the 802.11be standard. Non-AP STAs can also support various current and future 802.11 family wireless local area network (WLAN) standards, including 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

In some implementations, the frequency bands supported by WLAN technology may include, but are not limited to, low frequency bands (e.g., 2.4 GHz, 5 GHz, 6 GHz) and high frequency bands (e.g., 45 GHz, 60 GHz).

[0062] It should be understood that the specific forms of STA devices and AP devices in the embodiments of the present application are not particularly limited and are merely illustrative.

[0063] Ambient energy-based devices

[0064] In known wireless communication systems (for example, the NR systems and Wi-Fi systems described above), devices that rely on ambient energy are similar to passive or semi-passive zero-power devices in zero-power communications. Their operational energy typically comes from harvested ambient energy, which can be wireless signals, solar energy, thermal energy, and other sources. These devices offer advantages such as low cost and the absence of batteries, enabling low-cost, large-scale deployment and maintenance-free IoT devices. Therefore, current standards are exploring how to support these devices within existing wireless communication systems.

[0065] In the embodiments of the present application, the above-mentioned ambient energy-based device can be referred to as an AMP device, an ambient IoT (ambient IoT) or an AMP IoT device, etc.

[0066] assisting node

[0067] In some scenarios, the second device can send a signal to the first device (for example, an AMP device) to provide energy and / or power to the first device so that the first device can communicate with the second device. However, the second device is usually far away from the first device. In this case, the second device is required to have a higher transmission power. For some reasons (for example, regulatory rules of various countries and regions, etc.), there are restrictions on the maximum transmission power of the second device, which may cause the first device to take a long time to collect energy and / or power based on the signal transmitted by the second device at the maximum transmission power. Even when the first device is far away from the second device, the signal transmitted by the second device at the maximum transmission power may not reach the first device, which greatly limits the distance between the second device and the first device.

[0068] In other scenarios, the second device can send a wake-up signal to the first device (for example, an AMP device) to wake up the first device from sleep mode and communicate with the second device. However, the second device is usually far away from the first device. In this case, the second device is required to have a higher transmission power so that the first device can receive the wake-up signal. However, for some reasons (for example, regulatory rules in various countries and regions), the maximum transmission power of the second device is limited, which greatly limits the distance between the second device and the first device.

[0069] In response to the above problems, an auxiliary node is introduced to assist the communication process between the first device and the second device. However, how the auxiliary node assists the communication process between the first device and the second device has not been discussed in detail. Therefore, an embodiment of the present application provides a method for wireless communication, in which the auxiliary node can control the first device, for example, to provide energy and / or power to the first device, or for example, to wake up the first device. Compared with the traditional solution, the second device controlling the first device helps to reduce the requirements for the distance between the first device and the second device and improve the flexibility of communication between the first device and the second device.

[0070] In some implementations, the second device may include a network device, such as the network device 110 shown in Figure 1. In other implementations, the second device may be an AP, such as the AP 211 shown in Figure 2.

[0071] In some implementations, the first device may be a device that requires energy and / or power, or a device that requires awakening. For example, the first device may be an AMP device. In embodiments of the present application, the first device may be a terminal device, such as terminal device 120 shown in FIG. 1 . Furthermore, in embodiments of the present application, the first device may be a STA, such as STA 221 shown in FIG. 2 .

[0072] In some implementations, the auxiliary node is also referred to as an "AMP energizer." For example, the auxiliary node can provide energy and / or power to the first device. For another example, the auxiliary node can wake up the first device.

[0073] For ease of understanding, the following describes the auxiliary node-based communication architecture proposed in an embodiment of the present application in conjunction with Figures 3 and 4. As shown in Figure 3 , the auxiliary node can be connected to the second device via a wired connection. In some implementations, control signaling between the second device and the auxiliary node can be transmitted via higher-layer signaling. For example, control signaling can be transmitted via higher-layer signaling.

[0074] In some implementations, the information transmitted by the second device to the first device may be referred to as downlink information. Taking the second device as an AP and the first device as an AMP STA as an example, the information sent by the second device to the first device may be referred to as AMP DL.

[0075] In some implementations, the information transmitted by the first device to the second device may be referred to as uplink information. Taking the second device as an AP and the first device as an AMP STA as an example, the information sent by the first device to the second device may be referred to as AMP UL.

[0076] In some implementations, the auxiliary node and the second device may be viewed as a single logical entity, wherein the auxiliary node may be viewed as an electrical head of the second device and may be used to provide energy and / or power to the first device.

[0077] 4 , the auxiliary node may be connected to the second device via a wireless link. In some implementations, control signaling between the second device and the auxiliary node may be transmitted via a wireless link.

[0078] In some implementations, the information transmitted by the second device to the auxiliary device may be referred to as downlink information. Taking the second device as an AP as an example, the information sent by the second device to the auxiliary device may be referred to as a DL.

[0079] In some implementations, the information transmitted by the auxiliary device to the second device may be called uplink information. Taking the second device as an AP as an example, the information sent by the auxiliary device to the second device may be called an auxiliary node UL.

[0080] In some implementations, the information transmitted by the second device to the first device may be referred to as downlink information. Taking the second device as an AP and the first device as an AMP STA as an example, the information sent by the second device to the first device may be referred to as AMP DL.

[0081] In some implementations, the information transmitted by the first device to the second device may be referred to as uplink information. Taking the second device as an AP and the first device as an AMP STA as an example, the information sent by the first device to the second device may be referred to as AMP UL.

[0082] In some implementations, it is assumed that the communication protocol for communication between the auxiliary node and the second device is called the first communication protocol, and the communication protocol for communication between the auxiliary node and the second device is called the second communication protocol, wherein the first communication protocol and the second communication protocol may be different. For example, the first communication protocol may be a Wi-Fi communication protocol, and the second communication protocol may be a Bluetooth communication protocol. For another example, the second communication protocol may be a Wi-Fi communication protocol, and the first communication protocol may be a Bluetooth communication protocol. Of course, in an embodiment of the present application, the first communication protocol and the second communication protocol may be the same communication protocol. For example, the first communication protocol and the second communication protocol are both Wi-Fi communication protocols. For another example, the first communication protocol and the second communication protocol are both Bluetooth communication protocols.

[0083] In some implementations, the auxiliary node and the second device can be considered as independent logical entities, or in other words, the auxiliary node and the second device are logically separated. Taking a WiFi system as an example, if the second device is an AP, the auxiliary node can be a non-AP STA associated with the AP.

[0084] The following describes a wireless communication method according to an embodiment of the present application in conjunction with Figure 5. The method shown in Figure 5 includes step S510.

[0085] In step S510 , the assisting node sends a first signal to the first device.

[0086] In some implementations, the first signal is used for one or more of the following: providing energy and / or power to the first device for communicating with the second device; waking up the first device to communicate with the second device.

[0087] In some scenarios, if the first signal is used to provide the first device with energy and / or power for communicating with the second device, the first signal can also be called a "power supply signal" or a "power transmission signal". In this case, the auxiliary node can be regarded as the energy source of the first device.

[0088] In other scenarios, if the first signal is used to wake up the first device to communicate with the second device, the first signal can also be called a "wake-up signal."

[0089] In the embodiments of the present application, the power supply signal and the wake-up signal are not limited. For example, the power supply signal and the wake-up signal can be the same signal, or the first signal can be used to wake up the first device and provide energy and / or power to the first device. For another example, the power supply signal and the wake-up signal can be different signals.

[0090] The above describes the first signal in the embodiment of the present application. The following describes the transmission method of the first signal in the embodiment of the present application in combination with Examples 1 to 4.

[0091] Example 1: The first signal may be triggered based on the first event, or in other words, the sending of the first signal may be triggered based on the occurrence of the first event.

[0092] In some implementations, the first event is associated with one or more of the following: the second device has data to be transmitted to the first device; the second device instructs the auxiliary node to wake up the first device.

[0093] Taking the association of a first event with data to be transmitted from the second device to the first device as an example, in some implementations, the first event may include data to be transmitted from the second device to the first device, or the first event may include data to be transmitted from the second device to the first device, and the amount of data to be transmitted is greater than a threshold, wherein the threshold may be predefined, preconfigured, or configured by the network device.

[0094] In an embodiment of the present application, triggering the first signal based on a first event associated with data to be transmitted from the second device to the first device can be understood as triggering the first information based on the need for the second device to transmit data, that is, when there is data to be transmitted, the auxiliary node transmits the first signal to the first device, which helps to reduce the power consumption of the first device.

[0095] Taking the first event being associated with the second device instructing the auxiliary node to wake up the first device as an example, that is, in response to the auxiliary node receiving information sent by the second device instructing to wake up the first device, the auxiliary node may send a wake-up signal to the first device.

[0096] In the embodiments of the present application, the first signal triggered by the first event is not limited. For example, the first signal can be used to wake up the first device and provide energy and / or power to the first device. Of course, in the embodiments of the present application, the first signal can be used only to wake up the first device, or the first signal can be used only to provide energy and / or power to the first device.

[0097] Assume that both the wake-up signal and the power supply signal are first signals, the second device is an AP, the first device is a STA, and the first event includes data to be transmitted from the second device to the first device. When the AP has downlink data to transmit, the AP can instruct the auxiliary node to send the first signal to the STA to wake up the first device and provide energy and / or power to the first device.

[0098] Example 2: The first signal may be transmitted periodically.

[0099] In some implementations, the period of transmitting the first signal may be configured by the second device. Of course, in the embodiment of the present application, the period of transmitting the first signal may be predefined or preconfigured.

[0100] Assume that both the wake-up signal and the power supply signal are first signals, the second device is an AP, and the first device is a STA. In this case, the AP configures the auxiliary node to transmit the first signal at a period of period 1. Accordingly, the auxiliary node periodically transmits the first signal to the STA at period 1 to wake up the STA and provide energy and / or power to the STA.

[0101] In the embodiments of the present application, the periodically transmitted first signal is not limited. For example, the first signal may be used to wake up the first device and provide energy and / or power to the first device. Of course, in the embodiments of the present application, the first signal may be used only to wake up the first device, or the first signal may be used only to provide energy and / or power to the first device.

[0102] Example 3: If the first signal is used to wake up the first device to communicate with the second device, the above step S510 includes: when the auxiliary node continues to provide energy and / or power to the first device, in response to the occurrence of the first event, the auxiliary node sends the first signal to the first device.

[0103] In other words, the wake-up signal and the energy supply signal are different signals. The auxiliary node can continuously send the energy supply signal to the first device to provide energy and / or power to the first device. When the first event occurs, the auxiliary node can send the wake-up signal to the first device to wake up the first device.

[0104] It should be noted that the above-mentioned first event can be referred to the relevant introduction in Example 2. Taking the example that the first event includes data to be transmitted from the second device to the first device, the auxiliary node can always be in the on state and continuously send a power transmission signal to the first device for the first device to perform energy collection. Once the second device has data to be transmitted to the first device (i.e., the first event occurs), the second device can send an indication message to the auxiliary node via high-layer signaling to instruct the auxiliary node to wake up the first device.

[0105] In an embodiment of the present application, the auxiliary node can continuously provide energy and / or power to the first device, and notify the auxiliary node to wake up the first device only when the second device has a communication demand. The auxiliary node continuously provides energy and / or power to the first device, which helps to shorten the time for the first device to collect energy. In addition, the auxiliary node wakes up the first device only when the second device has a communication demand, which helps to reduce the power consumption of the first device.

[0106] Example 4: If the first signal is used to provide energy and / or power to the first device for communicating with the second device, the above method also includes: the auxiliary node receives the first information sent by the second device, and the first information is used to indicate the activation of the auxiliary node to provide energy and / or power to the first device.

[0107] In some implementations, the first information may be transmitted periodically. That is, the second device may periodically activate the auxiliary node using the first information to provide energy and / or power to the first device. Of course, in embodiments of the present application, the first information may be transmitted aperiodically. For example, the second device may send the first information to the auxiliary node based on the data to be transmitted.

[0108] In some implementations, the method further includes: the second device sending second information to the auxiliary node, where the second information is used to instruct the auxiliary node to wake up the first device.

[0109] In some implementations, the sending time of the first information and the sending time of the second information can be constrained based on the first constraint. For example, the first constraint may include that the sending time of the first information is earlier than the sending time of the second information, so that the first device can first collect energy and / or power before waking up the first device. For another example, the first constraint may include that the sending time of the first information is earlier than the sending time of the second information, and the sending time of the first information and the sending time of the second information are separated by a first time interval. The introduction of the first time interval helps the first device collect a certain amount of energy and / or power to support subsequent communication processes.

[0110] In the embodiments of the present application, the configuration of the first time interval is not limited. In some implementations, the first time interval can be determined based on a parameter (e.g., represented by "Tch"). For example, the parameter Tch can indicate the minimum time interval corresponding to the first time interval. For another example, the parameter Tch can be the duration of the first time interval. The above parameters can be predefined or preconfigured.

[0111] In some implementations, the first time interval is associated with the device type of the first device, or in other words, the setting of the first time interval can be related to the capabilities of the first device. For example, for a first device with a high energy and / or power collection efficiency, the duration of the first time interval can be relatively short, which helps to wake up the first device as soon as possible. For another example, for a first device with a low energy and / or power collection efficiency, the duration of the first time interval can be relatively long, which helps the first device collect a certain amount of energy and / or power so that it can communicate with the second device after waking up.

[0112] In the embodiment of the present application, the device type of the first device and the duration of the first time interval may be determined through an association relationship, and the association relationship may be preconfigured or predefined.

[0113] It should be noted that after receiving the first information, the auxiliary node usually sends a power supply signal to the first device. In addition, after receiving the second information, the auxiliary node usually sends a wake-up signal to the first device. Therefore, the above-mentioned first time interval can be understood as the time interval between the time when the wake-up signal is sent and the time when the power supply signal is sent. Of course, in the embodiment of the present application, it can also be understood that the time interval between the time when the wake-up signal is sent and the time when the power supply signal is sent is determined based on the first time interval.

[0114] Based on the above introduction, it can be seen that Example 3 and / or Example 4 can be applied to scenarios where the wake-up signal and the energy supply signal are different signals. In some implementations, if the wake-up signal and the energy supply signal are different signals, the end time of the energy supply signal can be determined based on the end time of the communication between the first device and the second device. For example, the end time of the energy supply signal can be later than or equal to the end time of the communication between the first device and the second device, that is, the auxiliary node can continue to provide energy and / or power to the first device until the communication between the first device and the second device ends.

[0115] In some scenarios, the second device can control the auxiliary node to provide energy and / or power to the first device, that is, the second device can activate the auxiliary node to provide energy and / or power to the first device until the communication between the second device and the first device ends. The second device can control the auxiliary node to stop providing energy and / or power to the first device, for example, the second device can deactivate the auxiliary node.

[0116] For ease of understanding, the following describes the transmission method of the wake-up signal and the power supply signal in an embodiment of the present application in conjunction with Figure 6. Assume that the second device is an AP and the first device is an AMP STA. As shown in Figure 6, at time t1, the AP sends information 1 to the auxiliary node to activate the auxiliary node to provide energy and / or power to the first device. In response to information 1, the auxiliary node sends a power supply signal to the AMP STA to provide energy and / or power to the first device. Accordingly, the AMP STA performs energy and / or power collection at time 1.

[0117] At time t2, the AP sends message 2 to the auxiliary node, instructing the auxiliary node to send a wake-up signal to the first device. In response to message 2, the auxiliary node sends a wake-up signal to the AMP STA to wake up the AMP STA. Accordingly, the AMP STA is activated at time 2 to communicate with the AP. A first time interval is provided between time t1 and time t2 to allow the AMP STA to collect a certain amount of energy. Furthermore, the auxiliary node may send a power supply signal to the AMP STA at a period T to provide energy and / or power to the AMP STA.

[0118] At time 3, the AP sends information 3 to the assisting node to instruct the assisting node to stop providing energy and / or power to the AMP STA. In other words, information 3 is used to instruct the assisting node to be deactivated.

[0119] In some scenarios, the second device may not be able to distinguish between the first device and the auxiliary node. For example, the communication protocol used between the auxiliary node and the second device may be the same as the communication protocol used between the first device and the second device (see the architecture shown in Figure 4). In this case, the second device may send a message indicating the activation of the auxiliary node to the first device, causing communication failure.

[0120] Therefore, to address the above issues, embodiments of the present application provide a method for distinguishing between an auxiliary node and a first device. In this method, the auxiliary node can send third information to a second device to indicate the node type of the auxiliary node. Accordingly, the second device can determine whether the sender of the third information is an auxiliary node or a first device based on the node type.

[0121] It should be understood that the above-mentioned node type can be replaced by "operation type", that is, the auxiliary node can send third information to the second device to indicate that the operation type of the auxiliary node is an auxiliary node. This embodiment of the present application does not limit this.

[0122] In some scenarios, since the auxiliary node and the first device may be close to each other, the communication between the second device and the auxiliary node may interfere with the communication between the second device and the first device. Therefore, to address the above problem, the above two types of communication can be carried out using time division multiplexing or frequency division multiplexing.

[0123] That is, the auxiliary node communicates with the first device based on a first transmission resource, and the auxiliary node communicates with the second device based on a second transmission resource, wherein the first transmission resource and the second transmission resource do not overlap in the time domain; or the first transmission resource and the second transmission resource do not overlap in the frequency domain. Of course, in the embodiment of the present application, the first transmission resource and the second transmission resource may not overlap in both the time domain and the frequency domain.

[0124] In some implementations, the first transmission resource and the second transmission resource may be configured by the second device. In other words, the second device may coordinate communications between the second device and the auxiliary node, and between the second device and the first device, using TDM or FDM.

[0125] In the embodiments of the present application, the first transmission resource and / or the second transmission resource are not limited. For example, the transmission resource may be a resource element (RE). For another example, the transmission resource may be a resource block (RB).

[0126] In some implementations, the transmission opportunity associated with the assisting node is shared with the second device. For example, the second device may be an AP and the first device may be an AMP STA. In this case, the AP may complete channel access. Subsequently, the AP may share the transmission opportunity (Txop) with the assisting node for a period of time, using a shared Txop mechanism, so that the assisting node can send a wake-up signal to the AMP STA. The AP may then terminate the shared Txop and communicate with the AMP STA via the Txop.

[0127] Of course, in an embodiment of the present application, the auxiliary node can perform channel access, or in other words, the auxiliary node can perform channel access with the assistance of the AP. In this way, the communication between the auxiliary node and the first device and the communication between the second device and the first device are independent of each other.

[0128] In some scenarios, a first device may be surrounded by multiple auxiliary nodes, and each of the multiple auxiliary nodes can provide energy and / or power to the first device. For some reasons, different auxiliary nodes among the multiple auxiliary nodes have different efficiencies in providing energy and / or power to the first device. For example, different auxiliary nodes have different capabilities, resulting in different auxiliary nodes having different efficiencies in providing energy and / or power to the first device. For another example, different auxiliary nodes have different distances from the first device, resulting in different auxiliary nodes having different efficiencies in providing energy and / or power to the first device. However, the second device is generally unable to learn the efficiency of different auxiliary nodes in providing energy and / or power to the first device, resulting in the second device being unable to select a suitable auxiliary node for the first device.

[0129] Therefore, in response to the above-mentioned problems, an embodiment of the present application provides a method for wireless communication. In this method, since the first device can know the efficiency of different auxiliary nodes in providing energy and / or power to the first device, the first device can assist the second device in selecting the auxiliary node associated with the first device (also referred to as the "first auxiliary node"), which helps to improve the rationality of selecting the auxiliary node for the first device.

[0130] The following describes a wireless communication method according to an embodiment of the present application in conjunction with FIG7 . Referring to FIG7 , in step S710 , the first device sends fourth information to the second device, where the fourth information is used by the second device to select a first auxiliary node for the first device. For details about the first auxiliary node, refer to the above description of the auxiliary node.

[0131] In some implementations, the fourth information is used to indicate one or more of the following: a first auxiliary node; a second device associated with the first auxiliary node; and a distance between the first device and the first auxiliary node.

[0132] In some implementations, the fourth information may indicate the first auxiliary node by carrying identification information of the first auxiliary node.

[0133] In some implementations, the fourth information may carry identification information of the second device associated with the first auxiliary node, thereby indicating the second device associated with the first auxiliary node, so that the second device can determine that the second device associated with the first auxiliary node is itself. In some scenarios, different auxiliary nodes may be associated with different second devices. In this case, the second device associated with the first auxiliary node can be determined based on the information of the second device associated with the first auxiliary node.

[0134] In some implementations, the fourth information may include the distance between the first device and the first auxiliary node. In this way, the second device may select a suitable auxiliary node for the first device as the first auxiliary node based on the information.

[0135] In the embodiment of the present application, there is no limitation on the method for determining the distance between the first device and the first auxiliary node. In some implementations, the distance between the first device and the first auxiliary node can be determined based on the position of the first device. For example, the first device can send the position information of the first device to the second device, and accordingly, the second device can determine the distance between the first device and the first auxiliary node based on the position information of the first device and the position information of the first auxiliary node. Of course, in the embodiment of the present application, the second device can use a positioning method to determine the position of the first device, wherein the positioning method can include GNSS positioning, base station positioning, WIFI positioning, etc.

[0136] In addition, in the embodiments of the present application, there is no limitation on the method for obtaining the location of the first auxiliary node. In some implementations, the location information of the first auxiliary node may be reported by the first auxiliary node to the second device, or the second device may determine the location of the first auxiliary node based on a positioning method, wherein the positioning method can be described above.

[0137] In some implementations, before step S710, the method further includes: the second device sending fifth information to the first auxiliary node.

[0138] In some implementations, the fifth information includes one or more of the following: an identifier of the first device; an identifier of the first auxiliary node; and an identifier of a second device associated with the first auxiliary node.

[0139] In some implementations, the identifier of the first device may be used to indicate the first device to which the first auxiliary node provides energy and / or power, and / or the identifier of the first device may be used to indicate the first device that the first auxiliary node needs to wake up.

[0140] In some implementations, the second device may indicate the identifier of the first auxiliary node and / or the identifier of the second device associated with the first auxiliary node to the first auxiliary node through the fifth information, so that the first auxiliary node can send the above information to the first device, and then the first device can send the fourth information based on the information.

[0141] In the embodiment of the present application, the fifth information is not limited. For example, the fifth information is used to instruct to provide energy and / or power to the first device, and / or the fifth indication information is used to instruct to wake up the first device.

[0142] In some implementations, the method further includes: the first auxiliary node sending second indication information to the first device, wherein the second indication information is used to indicate the first auxiliary node and / or the first auxiliary node is associated with the second device.

[0143] In some implementations, if the second indication information is used to indicate the first auxiliary node, the second indication information may carry identification information of the first auxiliary node. The identification information of the first auxiliary node may be indicated by the second device through the fourth information.

[0144] In some implementations, if the second indication information is used to indicate that the first auxiliary node is associated with the second device, or in other words, the second indication information is used to indicate the second device associated with the first auxiliary node, for example, the second indication information may carry identification information of the second device associated with the first auxiliary node. The identification information of the second device associated with the first auxiliary node may be sent by the second device to the first auxiliary node via the fourth information.

[0145] In some implementations, the method further includes: in response to the fourth information, the second device establishing an association between the first device and the first auxiliary node to simplify a subsequent process of selecting the first auxiliary node for the first device. The association may be presented in a table, for example.

[0146] In some scenarios, the first device is a mobile device. When the first device moves out of the coverage of the first auxiliary node, the second device may update the above association relationship.

[0147] In some implementations, the first auxiliary node is one of multiple auxiliary nodes associated with the second device, the distance between the first auxiliary node and the first device is smaller than the distance between the other auxiliary nodes and the first device, and the other auxiliary nodes are other nodes in the multiple auxiliary nodes other than the first auxiliary node. Generally, the greater the distance between the auxiliary node and the first device, the lower the efficiency of the auxiliary node in providing energy and / or power to the first device. Therefore, an auxiliary node that is closer to the first device can be used as the first auxiliary node to improve the efficiency of the first auxiliary node in providing energy and / or power to the first device.

[0148] In some implementations, if the first auxiliary node is one of multiple auxiliary nodes associated with the second device, the method further includes: the second device sending sixth information to the other auxiliary nodes, the sixth information being used to instruct deactivation of the other auxiliary nodes, where the other auxiliary nodes are nodes other than the first auxiliary node in the multiple auxiliary nodes. On the one hand, the second device can use the sixth information to deactivate the other auxiliary nodes to reduce power consumption of the auxiliary nodes. On the other hand, the second device can use the sixth information to deactivate the other auxiliary nodes to prevent interference with signal transmission by the first auxiliary node caused by signals transmitting energy and / or power from the other auxiliary nodes.

[0149] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 7 . The device embodiment of the present application is described in detail below in conjunction with Figures 8 to 14 . It should be understood that the description of the method embodiment corresponds to the description of the device embodiment.
