Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] Please refer to Figure 1, which shows a schematic diagram of a wireless communication system provided by an embodiment of the present application. As shown in Figure 1, the wireless communication system may include: an access point (AP) and a station (STA).

[0035] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.

[0036] In some embodiments, STAs may include AP STAs and non-AP STAs. Communication in a communication system may be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA may refer to a device that communicates with a STA. For example, a peer STA may be an AP or a non-AP STA.

[0037] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.

[0038] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone plays the role of AP.

[0039] APs and non-AP STAs can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0040] In some embodiments, a non-AP STA may support 802.11be. A non-AP STA may also support various current and future 802.11 family wireless LAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0041] In some embodiments, the AP may be a device supporting the 802.11be standard. The AP may also be a device supporting various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0042] In the embodiment of the present application, the STA may be a mobile phone, tablet computer, computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in self-driving, in-vehicle communication equipment, wireless device in remote medical, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, wireless device in smart home, wireless communication chip, ASIC (Application Specific Integrated Circuit), SOC (System on Chip), etc. that supports WLAN / WIFI technology.

[0043] The frequency bands supported by WLAN technology may include but are not limited to: low frequency bands (2.4 GHz, 5 GHz, 6 GHz) and high frequency bands (45 GHz, 60 GHz).

[0044] There are one or more links between the station and the access point. In some embodiments, the station and the access point support multi-band communication. For example, communication is performed simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, 45 GHz, and 60 GHz frequency bands, or communication is performed simultaneously on different channels of the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such a device is generally referred to as a multi-band device, or a multi-link device (MLD), sometimes also referred to as a multi-link entity or a multi-band entity. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.

[0045] A multi-link device including one or more APs may be referred to as an Access Point Multi-Link Device (AP MLD), and a multi-link device including one or more non-AP STAs may be referred to as a Non-Access Point Multi-Link Device (non-AP MLD).

[0046] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0047] An AP is a device deployed in a wireless local area network to provide wireless communication capabilities for STAs. A station may include: User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, a station may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, or a wearable device, but the embodiments of the present application are not limited thereto.

[0048] Optionally, both the station and the access point support the IEEE 802.11 standard.

[0049] In some embodiments, the communication system in the embodiments of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, an independent (SA) networking scenario, or a non-standalone (NSA) networking scenario.

[0050] In some embodiments, the communication system in the embodiments of the present application can be applied to an unlicensed spectrum, where the unlicensed spectrum can also be considered as a shared spectrum; or, the communication system in the embodiments of the present application can also be applied to an authorized spectrum, where the authorized spectrum can also be considered as an unshared spectrum.

[0051] In some embodiments, the communication system in the embodiments of the present application can be applied to the FR1 frequency band (corresponding to the frequency band range of 410MHz to 7.125GHz), can also be applied to the FR2 frequency band (corresponding to the frequency band range of 24.25GHz to 52.6GHz), and can also be applied to new frequency bands such as high-frequency bands corresponding to the frequency band range of 52.6GHz to 71GHz or the frequency band range of 71GHz to 114.25GHz.

[0052] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0053] The terms used in the embodiments of this application are intended only to explain the specific embodiments of this application and are not intended to limit this application. The terms "first," "second," "third," and "fourth," etc. in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0054] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0055] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0056] In the embodiments of the present application, "pre-definition" or "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device and a network device). The present application does not limit the specific implementation method. For example, pre-definition may refer to information defined in a protocol.

[0057] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communications field, for example, it may be an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or a protocol related to other communication systems. The present application does not limit the protocol type.

[0058] In order to facilitate a better understanding of the embodiments of the present application, the AMP device related to the present application is described.

[0059] AMP devices can harvest energy from a variety of sources, including radio frequency (RF), solar energy, and thermal energy. RF is the most controllable of all energy sources. For RF energy harvesting, narrow-bandwidth S1G signals are particularly well-suited for AMP devices due to their favorable propagation characteristics.

[0060] It's important to note that AMP devices are also referred to as ambient power enabled IoT devices, or Ambient IoT devices for short. Specifically, an Ambient IoT device refers to an IoT device that uses various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. Ambient IoT devices can have no energy storage capability or very limited energy storage capacity (such as using capacitors with a capacity of tens of microfarads).

[0061] In some embodiments, the Ambient IoT device can be used in at least the following four scenarios:

[0062] Object recognition, such as logistics, production line product management, and supply chain management;

[0063] Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of working environment and natural environment;

[0064] Positioning, such as indoor positioning, intelligent object search, and production line item positioning;

[0065] 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).

[0066] To facilitate a better understanding of the embodiments of the present application, a frequency division multiple access (FDMA) mode related to the present application is described.

[0067] When 802.11ba operates at 2.4 GHz, it can apply FDMA mode to transmit simultaneously on two channels, as shown in Figure 2. Using FDMA, multiple wake-up frames can be sent on a single frequency to address different wake-up radio (WUR) devices in different channels. However, the WUR channel can only carry the WUR device's identity (ID), and the channel bandwidth is not suitable for AMP devices, especially in the S1G band.

[0068] This application proposes an FDMA design for AMP devices, providing an FDMA design for uplink (UL) and / or downlink (DL) AMP devices, as well as S1G 2.4 / 5GHz AMP devices. Through the FDMA design, network devices (such as access points) can simultaneously address more AMP devices, which is necessary for large-scale AMP deployments, thereby improving the communication performance of AMP devices. In addition, when there is a large amount of data to address a single AMP device, the FDMA design also allows the AMP device to receive more data carried by multiple channels, thereby improving the communication performance of the AMP device.

[0069] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0070] FIG3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG3 , the wireless communication method 200 may include at least part of the following contents:

[0071] S210, the AMP device negotiates first information with the network side; wherein the first information is used to indicate whether the AMP device supports uplink FDMA and / or downlink FDMA.

[0072] In an embodiment of the present application, the AMP device negotiates with the network side before transmission whether the AMP device supports uplink FDMA and / or downlink FDMA, and by designing uplink FDMA and / or downlink FDMA, the communication performance of the AMP device can be improved.

[0073] It should be noted that AMP devices represent a huge market in many scenarios, such as smart homes, smart manufacturing, and logistics / warehouses. Due to their ultra-low cost and maintenance-free nature, AMP devices have opened up a whole new market. The technical solution of this application can be used when cost-effective, maintenance-free, and high-precision AMP device positioning is required. The embodiments of this application are applicable to a communication system based on AMP devices, which can support uplink FDMA and / or downlink FDMA.

[0074] In some embodiments, the network side that negotiates with the AMP device, that is, the network device, may be one of the following: an access point (AP), a transmission reception point (TRP), or a base station.

[0075] In some embodiments, the embodiments of the present application may be applied to S1G 2.4 GHz or S1G 5 GHz.

[0076] In an embodiment of the present application, the AMP device may include a backscatter (BS) transmitter, wherein the backscatter signal transmitted by the backscatter transmitter may be a signal on one FDMA channel or a signal on multiple FDMA channels.

[0077] Example 1: The backscatter transmitter includes a single channel filter. In this case, the backscatter transmitter can only receive and backscatter signals in one FDMA channel.

[0078] In Example 2, the backscatter transmitter includes multiple channel filters. In this case, the backscatter transmitter can receive and backscatter signals on multiple FDMA channels. As shown in Figure 4, AP 1 transmits simultaneously on two FDMA channels. The backscatter transmitter on the AMP device uses two channel filters to filter out the two FDMA channels and modulates FDMA channel 0 and FDMA channel 1 using on-off keying (OOK) modulation to produce two data streams (i.e., two signals). The OOK-modulated signals are then reflected on different FDMA channels and received by AP 2.

[0079] In both of the above examples, the AMP device needs to indicate to the associated AP (such as AP 1 and AP 2 in Figure 4) whether it can support FDMA and how many FDMA channels it can support at most, especially in Example 2. The different backscattered signals emitted by the AMP device may be frequency-shifted or not, which means that the frequency offsets of multiple FDMA channels can be maintained or changed by the AMP device when reflected. If the frequency offset changes, such information should be indicated to the receiving AP, such as AP 2 in Figure 4, before backscatter transmission. This frequency shift capability of the AMP device should also be indicated to the associated AP (such as AP 1 and AP 2 in Figure 4). It should be noted that Figure 4 is applied to a bi-static backscattering communication scenario, that is, the incoming signal received by the AMP device and the backscattered signal transmitted correspond to different devices (that is, AP 1 and AP 2, respectively). Of course, the embodiments of the present application can also be applied to a mono-static backscattering communication scenario, that is, the incoming signal received by the AMP device and the backscattered signal transmitted correspond to the same device.

[0080] It should be noted that in the embodiment of the present application, non-AMP devices (such as STA) can recognize the legacy preamble, AMP devices cannot recognize the legacy preamble, and AMP devices can recognize the FDMA channel following the legacy preamble.

[0081] In some embodiments, when the AMP device supports uplink FDMA and / or downlink FDMA, the first information includes but is not limited to at least one of the following:

[0082] The maximum number of uplink FDMA channels supported by the AMP device;

[0083] The maximum number of downlink FDMA channels supported by the AMP device;

[0084] The maximum number of downlink FDMA channels supported by the AMP device when multiple downlink FDMA channels are addressed;

[0085] The maximum frequency offset between multiple uplink FDMA channels supported by the AMP device;

[0086] The maximum frequency offset between multiple downlink FDMA channels supported by the AMP device;

[0087] The number of uplink FDMA channels;

[0088] Number of downlink FDMA channels;

[0089] Frequency offset between multiple uplink FDMA channels;

[0090] Frequency offset between multiple downlink FDMA channels;

[0091] Whether multiple uplink FDMA channels correspond to the same legacy preamble;

[0092] Whether multiple downlink FDMA channels correspond to the same legacy preamble;

[0093] In the case where multiple uplink FDMA channels correspond to the same legacy preamble, the maximum number of uplink FDMA channels within one preamble bandwidth;

[0094] When multiple downlink FDMA channels correspond to the same legacy preamble, the maximum number of downlink FDMA channels within one preamble bandwidth.

[0095] For example, when the AMP device at least supports uplink FDMA, the first information includes but is not limited to at least one of the following:

[0096] The maximum number of uplink FDMA channels supported by the AMP device;

[0097] The maximum frequency offset between multiple uplink FDMA channels supported by the AMP device;

[0098] The number of uplink FDMA channels;

[0099] Frequency offset between multiple uplink FDMA channels;

[0100] Whether multiple uplink FDMA channels correspond to the same legacy preamble;

[0101] When multiple uplink FDMA channels correspond to the same legacy preamble, the maximum number of uplink FDMA channels within one preamble bandwidth.

[0102] For example, when the AMP device supports at least downlink FDMA, the first information includes but is not limited to at least one of the following:

[0103] The maximum number of downlink FDMA channels supported by the AMP device;

[0104] The maximum number of downlink FDMA channels supported by the AMP device when multiple downlink FDMA channels are addressed;

[0105] The maximum frequency offset between multiple downlink FDMA channels supported by the AMP device;

[0106] Number of downlink FDMA channels;

[0107] Frequency offset between multiple downlink FDMA channels;

[0108] Whether multiple downlink FDMA channels correspond to the same legacy preamble;

[0109] When multiple downlink FDMA channels correspond to the same legacy preamble, the maximum number of downlink FDMA channels within one preamble bandwidth.

[0110] In some embodiments, when an AMP device supports uplink FDMA and / or downlink FDMA, the AMP device receives second information dynamically configured by a network side (e.g., a network device); wherein the second information includes, but is not limited to, at least one of the following: the number of uplink FDMA channels, the number of downlink FDMA channels, the frequency offset between multiple uplink FDMA channels, and the frequency offset between multiple downlink FDMA channels. In other words, the network device can dynamically configure some FDMA channel parameters during transmission.

[0111] For example, in the case where the AMP device supports uplink FDMA, the second information includes but is not limited to at least one of the following: the number of uplink FDMA channels, and the frequency offset between multiple uplink FDMA channels.

[0112] For example, in the case where the AMP device supports downlink FDMA, the second information includes but is not limited to at least one of the following: the number of downlink FDMA channels, and the frequency offset between multiple downlink FDMA channels.

[0113] In some embodiments, when the AMP device supports uplink FDMA, the number of uplink FDMA channels is 2n, where n is a positive integer. For example, when the AMP device supports uplink FDMA, as shown in Figure 5, the number of uplink FDMA channels is one of the following: 2, 4, 8, or 16. In Figure 5, the bandwidth of the uplink FDMA channels is 1 MHz. In this embodiment, with up to 16 uplink FDMA channels, the AMP device can transmit more data or transmit data to more APs.

[0114] In some embodiments, when the AMP device supports uplink FDMA, if the bandwidth of the uplink FDMA channel is 1 MHz, 2 MHz, 8 MHz, or 16 MHz, the maximum number of uplink FDMA channels is 16.

[0115] In some embodiments, when the AMP device supports uplink FDMA, if the bandwidth of the uplink FDMA channel is 250 kHz, the maximum number of uplink FDMA channels is 20.

[0116] Specifically, different maximum numbers of uplink FDMA channels may apply to different regions / countries. For example, some regions / countries support uplink FDMA channel bandwidths of 1 MHz, 2 MHz, 8 MHz, or 16 MHz. In this case, the maximum number of uplink FDMA channels may be 16. For another example, some regions / countries support uplink FDMA channel bandwidths of 250 kHz. In this case, the maximum number of uplink FDMA channels may be 20.

[0117] In some embodiments, when the AMP device supports uplink FDMA, one uplink FDMA channel corresponds to one network device. That is, each uplink FDMA channel can address a different network device, wherein different uplink FDMA channels carry different network device identifiers (IDs).

[0118] In some embodiments, when the AMP device supports uplink FDMA, multiple uplink FDMA channels correspond to one network device. That is, multiple uplink FDMA channels can address the same network device, so that the AMP device can upload more uplink data to a single network device at one time.

[0119] In some embodiments, when multiple uplink FDMA channels correspond to one network device, a target uplink FDMA channel among the multiple uplink FDMA channels carries identification information of the network device corresponding to the multiple uplink FDMA channels. Optionally, the target uplink FDMA channel is a primary uplink FDMA channel among the multiple uplink FDMA channels, or the target uplink FDMA channel is the uplink FDMA channel with the largest or smallest index among the multiple uplink FDMA channels.

[0120] For example, as shown in Figure 6, uplink FDMA channels 0-4 are used for network device 1, and uplink FDMA channels 5-7 are used for network device 2. The IDs of network device 1 and network device 2 can be carried in uplink FDMA channel 0 and uplink FDMA channel 5, respectively, and the data of network device 1 and network device 2 can be carried in uplink FDMA channels 0-4 and uplink FDMA channels 5-7, respectively.

[0121] In some embodiments, when the length of the uplink data to be transmitted is fixed and the uplink data to be transmitted does not occupy all uplink FDMA channels among the multiple uplink FDMA channels, the unoccupied portions of the multiple uplink FDMA channels by the uplink data to be transmitted are padded with zeros. Of course, the unoccupied portions of the multiple uplink FDMA channels by the uplink data to be transmitted may also be padded with other information, which is not limited in the embodiments of the present application.

[0122] In some embodiments, when the AMP device supports uplink FDMA, a correspondence exists between a legacy preamble and an uplink FDMA channel. Optionally, the correspondence between the legacy preamble and the uplink FDMA channel includes at least one of the following: one legacy preamble corresponds to one uplink FDMA channel, and one legacy preamble corresponds to multiple uplink FDMA channels.

[0123] In some embodiments, the number of uplink FDMA channels corresponding to a single AMP device is determined based on the bandwidth of the traditional preamble code, or the number of uplink FDMA channels corresponding to a single AMP device is agreed upon by the protocol, or the number of uplink FDMA channels corresponding to a single AMP device is configured by the network.

[0124] In some embodiments, a 1 MHz legacy preamble may support up to five uplink FDMA channels in the 920-925 MHz frequency band.

[0125] For example, a traditional preamble is followed by a narrow uplink FDMA channel, as shown in a of FIG7 .

[0126] For example, a legacy preamble is followed by two narrower uplink FDMA channels, and the number of uplink FDMA channels following each legacy preamble is the same, as shown in b of Figure 7. The uplink FDMA channel addressing a single network device may or may not be constrained by the bandwidth of the legacy preamble.

[0127] For another specific example, a legacy preamble is followed by one or two narrower uplink FDMA channels, some legacy preambles are followed by one narrower uplink FDMA channel, and some legacy preambles are followed by two narrower uplink FDMA channels. Different legacy preambles may have different numbers of uplink FDMA channels following them, as shown in c in Figure 7. The uplink FDMA channel addressing a single network device may or may not be constrained by the bandwidth of the legacy preamble.

[0128] In some embodiments, when the AMP device supports downlink FDMA, the number of downlink FDMA channels is 2m, where m is a positive integer. For example, when the AMP device supports downlink FDMA, as shown in FIG8 , the number of downlink FDMA channels is one of the following: 2, 4, 8, or 16. In FIG8 , the bandwidth of the downlink FDMA channels is 1 MHz. In this embodiment, with up to 16 downlink FDMA channels, more AMP devices can be addressed, or the network device can transmit more data to the AMP device.

[0129] In some embodiments, when the AMP device supports downlink FDMA, if the bandwidth of the downlink FDMA channel is 1 MHz, 2 MHz, 8 MHz, or 16 MHz, the maximum number of downlink FDMA channels is 16.

[0130] In some embodiments, when the AMP device supports downlink FDMA, if the bandwidth of the downlink FDMA channel is 250 kHz, the maximum number of downlink FDMA channels is 20.

[0131] Specifically, different maximum numbers of downlink FDMA channels may apply to different regions / countries. For example, for some regions / countries, the bandwidth of the downlink FDMA channels supported is 1 MHz, 2 MHz, 8 MHz, or 16 MHz. In this case, the maximum number of downlink FDMA channels may be 16. For another example, for some regions / countries, the bandwidth of the downlink FDMA channels supported is 250 kHz. In this case, the maximum number of downlink FDMA channels may be 20.

[0132] In some embodiments, when the AMP device supports downlink FDMA, one downlink FDMA channel corresponds to one AMP device. That is, each downlink FDMA channel can address a different AMP device, wherein different downlink FDMA channels carry different AMP device identifiers (IDs).

[0133] In some embodiments, when an AMP device supports downlink FDMA, multiple downlink FDMA channels correspond to a single AMP device. That is, multiple downlink FDMA channels can address the same AMP device, allowing a network device (e.g., an AP) to transmit more downlink data to a single AMP device at once. In other words, a network device (e.g., an AP) can address more AMP devices simultaneously, which is essential for large-scale deployments of AMP devices. Furthermore, when there is a large amount of data to address a single AMP device, the FDMA design allows the AMP device to receive more data carried by multiple downlink FDMA channels.

[0134] In some embodiments, when multiple downlink FDMA channels correspond to one AMP device, a target downlink FDMA channel among the multiple downlink FDMA channels carries identification information of the AMP device corresponding to the multiple downlink FDMA channels. Optionally, the target downlink FDMA channel is a primary downlink FDMA channel among the multiple downlink FDMA channels, or the target downlink FDMA channel is the downlink FDMA channel with the largest or smallest index among the multiple downlink FDMA channels.

[0135] For example, as shown in Figure 9, downlink FDMA channels 0-4 are used for AMP device 1, and downlink FDMA channels 5-7 are used for AMP device 2. The IDs of AMP device 1 and AMP device 2 can be carried in downlink FDMA channel 0 and downlink FDMA channel 5, respectively, and the data of AMP device 1 and AMP device 2 can be carried in downlink FDMA channels 0-4 and downlink FDMA channels 5-7, respectively.

[0136] In some embodiments, when the length of the downlink data to be transmitted is fixed and the downlink data to be transmitted does not occupy all downlink FDMA channels in the multiple downlink FDMA channels, the unoccupied portions of the multiple downlink FDMA channels by the downlink data to be transmitted are padded with zeros. Of course, the unoccupied portions of the multiple downlink FDMA channels by the downlink data to be transmitted may also be padded with other information, and this is not limited in the embodiments of the present application.

[0137] In some embodiments, when the AMP device supports downlink FDMA, a correspondence exists between a legacy preamble and a downlink FDMA channel. Optionally, the correspondence between the legacy preamble and the downlink FDMA channel includes at least one of the following: one legacy preamble corresponds to one downlink FDMA channel, and one legacy preamble corresponds to multiple downlink FDMA channels.

[0138] In some embodiments, the number of downlink FDMA channels corresponding to a single AMP device is determined based on the bandwidth of the traditional preamble code, or the number of downlink FDMA channels corresponding to a single AMP device is agreed upon by the protocol, or the number of downlink FDMA channels corresponding to a single AMP device is configured by the network.

[0139] In some embodiments, a 1 MHz legacy preamble may support up to five downlink FDMA channels in the 920-925 MHz frequency band.

[0140] For example, a traditional preamble is followed by a narrower downlink FDMA channel, as shown in a of FIG10 .

[0141] For example, a legacy preamble is followed by two narrower downlink FDMA channels, and the number of downlink FDMA channels following each legacy preamble is the same, as shown in b of Figure 10. The downlink FDMA channel addressing a single AMP device can be constrained by the bandwidth of the legacy preamble or not.

[0142] For another specific example, a legacy preamble is followed by one or two narrower downlink FDMA channels, and some legacy preambles are followed by one narrower downlink FDMA channel, while others are followed by two narrower downlink FDMA channels. Different legacy preambles may have different numbers of downlink FDMA channels following them, as shown in c in Figure 10. The downlink FDMA channel addressing a single AMP device may or may not be constrained by the bandwidth of the legacy preamble.

[0143] Therefore, in an embodiment of the present application, the AMP device negotiates with the network side before transmission whether the AMP device supports uplink FDMA and / or downlink FDMA, and by designing uplink FDMA and / or downlink FDMA, the communication performance of the AMP device can be improved.

[0144] Specifically, if an AMP device supports downlink FDMA, network equipment (such as an AP) can address more AMP devices simultaneously, which is necessary for large-scale AMP deployments. In addition, when there is a large amount of data to address a single AMP device, the FDMA design also allows the AMP device to receive more data carried by multiple channels.
