Embodiments for Carrying out the Invention

[0017] Hereinafter, the technical solutions in the embodiments of the present application will be described in connection with the drawings of the embodiments of the present application. It is clear that the described embodiments are some of the embodiments of the present application, not all of the embodiments. For the embodiments of the present application, all other embodiments obtained by those skilled in the art without inventive work are within the protection scope of the present application.

[0018] The technical solutions of the embodiments of this application can be applied to various communication systems, such as Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), or other communication systems. For example, the technical solutions of the embodiments of this application include Global System of Mobile communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS) systems, Long Term Evolution (LTE) systems, Advanced long term evolution (LTE-A) systems, New Radio (NR) systems, NR system evolution systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, Non-Terrestrial Networks (NTN) systems, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Network (WLAN), and the Internet of Things (Internet of Things). Communication systems such as Things (IoT), 5th Generation (5G) systems, and 6th Generation (6G) systems.

[0019] Referring to Figure 1, a schematic diagram of a wireless communication system according to one embodiment of the present application is shown. As shown in Figure 1, the wireless communication system may include an access point (AP) and a station (STA).

[0020] In some scenarios, AP may also be called AP STA, meaning that AP is, in a sense, a type of STA. In some scenarios, STA is also called non-AP STA.

[0021] In some embodiments, the STA may include AP STAs and non-AP STAs. Communication in the communication system may be between an AP and a non-AP STA, between two non-AP STAs, or between an STA and a peer STA. Here, the peer STA can refer to the device communicating with the STA. For example, the peer STA may be an AP or a non-AP STA.

[0022] An AP (Access Point) is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect each wireless network client to each other and to connect the wireless network to Ethernet. An AP device may be a terminal device (e.g., a mobile phone) or a network device (e.g., a router) that has a Wireless Fidelity (Wi-Fi) chip.

[0023] It's important to understand that the role of an STA in a communication system is not absolute. For example, in some scenarios, a mobile phone acts as a non-AP STA when connected to routing, and as an AP when it's a hotspot for other mobile phones.

[0024] AP and non-AP STA may include devices applied to vehicle networks, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remotes, smart water meters in smart homes, and sensors in smart cities.

[0025] In some implementations, non-AP STA can support the 802.11be standard. Non-AP STA can also support current and future 802.11 family wireless LAN standards, including 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0026] In some embodiments, the AP may be a device that supports the 802.11be standard. The AP may also be a device that supports current and future 802.11 family WLAN standards such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0027] In the embodiments of this application, STA may be a mobile phone, tablet, 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 device, wireless device in remote medical, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, or wireless device in smart home, wireless communication chip, ASIC (Application Specific Integrated Circuit), SOC (System on Chip), etc., that supports WLAN / WIFI technology.

[0028] The frequency bands that WLAN technology can support include, but are not limited to, low-frequency bands (2.4GHz, 5GHz, 6GHz) and high-frequency bands (45GHz, 60GHz).

[0029] One or more links exist between the station and the access point. In some embodiments, the station and access point support multiband communication. For example, simultaneous communication in the 2.4GHz, 5GHz, 6GHz, 45GHz, and 60GHz frequency bands, or simultaneous communication on different channels in the same frequency band (or different frequency bands), improves communication throughput and / or reliability between devices. Such devices are generally called multiband devices or multi-link devices (MLDs), and may also be called multilink entities or multiband entities. A multilink device may be an access point device or a station device. If the multilink device is an access point device, it includes one or more APs, and if the multilink device is a station device, it includes one or more non-AP STAs.

[0030] A multilink device containing one or more APs may be called an Access Point Multi-Link Device (AP MLD), and a multilink device containing one or more non-AP STAs may be called a Non Access Point Multi-Link Device.

[0031] In the embodiments of this application, AP includes multiple APs, Non-AP includes multiple STAs, and multiple links can be formed between APs in AP and STAs in Non-AP, and data communication can be performed between APs in AP and corresponding STAs in Non-AP via the corresponding links.

[0032] An AP is a device deployed in a wireless LAN that provides wireless communication capabilities to a STA. A station may include user equipment (UE), access terminals, subscriber units, subscriber stations, mobile stations, mobile consoles, remote stations, remote terminals, mobile devices, wireless communication devices, user agents, or user equipment. Alternatively, a station may be a mobile phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, or wearable device, and the embodiments of this application are not limited thereto.

[0033] Alternatively, both the station and the access point support the IEEE 802.11 standard.

[0034] In some embodiments, the communication system in the embodiments of this application can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, standalone (SA) network construction scenarios, or non-standalone network construction scenarios.

[0035] In some embodiments, the communication system in the embodiments of this application may be applied to an unlicensed spectrum, which may also be considered a shared spectrum, or the communication system in the embodiments of this application may also be applied to a licensed spectrum, which may also be considered a non-shared spectrum.

[0036] In some embodiments, the communication system in the embodiments of this application can be applied to the FR1 frequency band (corresponding to the frequency band of 410 MHz to 7.125 GHz), the FR2 frequency band (corresponding to the frequency band of 24.25 GHz to 52.6 GHz), and further, to new frequency bands such as high frequency bands corresponding to the frequency band of 52.6 GHz to 71 GHz, or the frequency band of 71 GHz to 114.25 GHz.

[0037] It should be understood that the terms “system” and “network” are often used interchangeably within this specification. In this specification, the term “and / or” is merely a relational relationship used to describe related objects, meaning that three such relationships are possible; for example, A and / or B means that A exists alone, A and B exist simultaneously, or B exists alone. Also, in this specification, the symbol “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0038] The terminology used in the embodiments of this application is for the sole purpose of describing the specific embodiments of this application and is not intended to limit this application. In the specification, claims, and drawings of this application, terms such as “first,” “second,” “third,” and “fourth” are used to distinguish different subjects and are not used to describe a particular order. Furthermore, the terms “includes” and “have” and their variations are intended to cover non-exclusive inclusion.

[0039] It should be understood that the term "instruction" as used in the embodiments of this application can mean that there is a relationship, whether direct or indirect. For example, A instructing B may mean that A directly instructs B, for example, that B can be obtained by A; or A indirectly instructs B, for example, if A instructs C, it may mean that B can be obtained by C; and it may also mean that there is a relationship between A and B.

[0040] In the description of the embodiments of this application, the term "correspondence" may mean that there is a direct or indirect correspondence between the two, or that there is a related relationship between the two, or that there is a relationship such as instruction and instruction, setting and setting.

[0041] In the embodiments of this application, “predefined” or “preconfigured” can be achieved by pre-storing corresponding codes, forms, or other methods that can be used to indicate relevant information in devices (e.g., including terminal devices and network devices), and this application does not limit its specific embodiments. For example, “predefined” may refer to something defined in a protocol.

[0042] In the embodiments of this application, the “protocol” may refer to a standard protocol in the field of communications, such as an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or other protocols related thereto, but this application does not limit the type of protocol.

[0043] To facilitate understanding of the embodiments of this application, the AMP equipment related to this application will be described.

[0044] Amplifier (AMP) equipment can obtain energy from various energy sources, including radio frequency (RF), solar energy, and thermal energy. Of all energy sources, radio frequency is the most controllable. In the case of radio frequency RF energy collection, narrow-bandwidth S1G signals are more suitable for energy collection by AMP equipment due to their good propagation characteristics.

[0045] AMP devices are also called Ambient power-enabled IoT devices, or simply Ambient IoT devices. Specifically, an Ambient IoT device refers to an IoT device that uses various ambient energy sources such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. An Ambient IoT device does not need to have energy storage capabilities, or it may have very limited energy storage capabilities (for example, using a capacitor with a capacitance of several tens of microfarads (uF)).

[0046] In some embodiments, the Ambient IoT device can be used in at least the following four scenarios: Object recognition, for example, in logistics, production line product management, and supply chain management. Environmental monitoring, such as monitoring temperature, humidity, and hazardous gases in operating and natural environments. Positioning, such as indoor positioning, smart trackers, and production line item positioning. Smart control, for example, smart control of various electrical appliances in a smart home (turning air conditioners on / off, temperature adjustment), and smart control of various facilities in agricultural greenhouses (automatic watering, fertilization).

[0047] To facilitate a better understanding of the embodiments of this application, the frequency division multiple access (FDMA) modes relevant to this application will be described.

[0048] When 802.11ba operates at 2.4 GHz, as shown in Figure 2, simultaneous transmission on two channels is possible by applying FDMA mode. Using FDMA, multiple wake-up frames can be transmitted on a single frequency to address different wake-up radio (WUR) devices on different channels. However, the WUR channel can only carry the WUR device's identifier (ID), and the channel bandwidth is not suitable for AMP devices, especially in the S1G band.

[0049] This application proposes an FDMA design for AMP devices that provides an FDMA design for uplink (UL) and / or downlink (DL) and S1G 2.4 / 5GHz AMP devices. The FDMA design allows network equipment (e.g., APs) to address more AMP devices simultaneously, which is necessary when deploying AMP devices on a large scale and thereby improves the communication performance of the 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 channels, thereby improving the communication performance of the AMP device.

[0050] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below by specific embodiments. The following related technologies can be optionally combined with the technical solutions of the embodiments of this application as selectable solutions, and all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least a portion of the following.

[0051] Figure 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application, and as shown in Figure 3, the wireless communication method 200 may include at least some of the following:

[0052] S210, the AMP device negotiates with the network side for first information indicating whether the AMP device supports uplink FDMA and / or downlink FDMA.

[0053] In the embodiments of this application, the communication performance of the AMP device can be improved by negotiating with the network side whether the AMP device supports uplink FDMA and / or downlink FDMA before transmission, and by designing uplink FDMA and / or downlink FDMA.

[0054] Furthermore, AMP devices have a large market in many scenarios, such as smart homes, smart manufacturing, and logistics / warehousing. Their ultra-low cost and maintenance-free functionality have opened up entirely new markets for AMP devices. The technical solutions of this application can be used when cost-effective, maintenance-free, and highly accurate AMP device positioning is required. The embodiments of this application are applicable to communication systems using AMP devices capable of supporting uplink FDMA and / or downlink FDMA.

[0055] In some embodiments, the network side negotiating with the AMP device, i.e., the network device, may be one of the following: an access point (AP), a transmission / reception point (TRP), or a base station.

[0056] In some embodiments, the embodiments of this application can be applied to S1G 2.4GHz or S1G 5GHz.

[0057] In embodiments of this application, the AMP device may include a backscatter (BS) transmitter, and the backscatter signal transmitted from the backscatter transmitter may be a signal on one FDMA channel or a signal on multiple FDMA channels.

[0058] In Example 1, the backscatter transmitter includes a single-channel filter, in which case the backscatter transmitter can receive and backscatter signals on only one FDMA channel.

[0059] In Example 2, the backscatter transmitter includes multiple channel filters, in which case the backscatter transmitter can receive and backscatter signals on multiple FDMA channels. As shown in Figure 4, AP1 transmits using two FDMA channels simultaneously, but the AMP device's backscatter transmitter filters the two FDMA channels using two channel filters, modulating FDMA channel 0 and FDMA channel 1 respectively with on-off keying (OOK) modulation to obtain two data streams (i.e., two signals). The OOK-modulated signals are reflected on different FDMA channels and received by AP2.

[0060] In the two examples above, the AMP device needs to indicate to the relevant APs (AP1 and AP2 in Figure 4), particularly in Example 2, whether the AMP device itself can support FDMA and the maximum number of FDMA channels it can support. Different backscattered signals transmitted from the AMP device may or may not be frequency-shifted, meaning that the frequency offsets of multiple FDMA channels may be retained or modified by the AMP device when reflected. If a change in frequency offset occurs, such information should be indicated to the receiving AP, such as AP2 in Figure 4, before the transmission of the backscatter. This frequency-shifting capability of the AMP device should also be indicated to the relevant APs (AP1 and AP2 in Figure 4). Note that Figure 4 applies to a bistatic backscattering scenario, i.e., a scenario in which the incoming signal received by the AMP device and the backscattered signals transmitted from the AMP device correspond to different devices (i.e., AP1 and AP2, respectively). Naturally, the embodiments of this application are also applicable to monostatic backscatter communication scenarios, i.e., scenarios in which the incoming signal received by the AMP device and the backscattered signal transmitted from the AMP device correspond to the same device.

[0061] In the embodiments described herein, non-AMP devices (e.g., STA) can identify legacy preambles, AMP devices cannot identify legacy preambles, and AMP devices can identify the FDMA channel following the legacy preamble.

[0062] In some embodiments, if the AMP equipment supports uplink FDMA and / or downlink FDMA, the first information is: The maximum number of uplink FDMA channels supported by the AMP device, The maximum number of downlink FDMA channels supported by the AMP device, The maximum number of downlink FDMA channels that the AMP device supports when there are multiple downlink FDMA channel addressings, The maximum frequency offset between the multiple uplink FDMA channels supported by the AMP device, The maximum frequency offset between multiple downlink FDMA channels supported by the AMP device, The number of uplink FDMA channels, The number of downlink FDMA channels, Frequency offset between multiple uplink FDMA channels, Frequency offset between multiple downlink FDMA channels, Whether multiple uplink FDMA channels correspond to the same legacy preamble, Whether multiple downlink FDMA channels support the same legacy preamble, When multiple uplink FDMA channels correspond to the same legacy preamble, the maximum number of uplink FDMA channels within a single preamble bandwidth is, When multiple downlink FDMA channels correspond to the same legacy preamble, this includes, but is not limited to, at least one of the maximum number of downlink FDMA channels within a single preamble bandwidth.

[0063] Specifically, for example, if the AMP device supports at least uplink FDMA, the first information is: The maximum number of uplink FDMA channels supported by the AMP device, The maximum frequency offset between the multiple uplink FDMA channels supported by the AMP device, The number of uplink FDMA channels, Frequency offset between multiple uplink FDMA channels, Whether multiple uplink FDMA channels correspond to the same legacy preamble, When multiple uplink FDMA channels correspond to the same legacy preamble, this includes, but is not limited to, at least one of the maximum number of uplink FDMA channels within a single preamble bandwidth.

[0064] Specifically, for example, if the AMP device supports at least downlink FDMA, the first information is: The maximum number of downlink FDMA channels supported by the AMP device, The maximum number of downlink FDMA channels that the AMP device supports when there are multiple downlink FDMA channel addressings, The maximum frequency offset between multiple downlink FDMA channels supported by the AMP device, The number of downlink FDMA channels, Frequency offset between multiple downlink FDMA channels, Whether multiple downlink FDMA channels support the same legacy preamble, When multiple downlink FDMA channels correspond to the same legacy preamble, this includes, but is not limited to, at least one of the maximum number of downlink FDMA channels within a single preamble bandwidth.

[0065] In some embodiments, if the AMP device supports uplink FDMA and / or downlink FDMA, the AMP device receives second information dynamically set on the network side (e.g., network equipment), which includes, but is not limited to, 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 equipment can dynamically set several FDMA channel parameters during transmission.

[0066] Specifically, for example, if an AMP device supports uplink FDMA, the second information includes, but is not limited to, at least one of the number of uplink FDMA channels and the frequency offset between multiple uplink FDMA channels.

[0067] Specifically, for example, if an AMP device supports downlink FDMA, the second information includes, but is not limited to, at least one of the number of downlink FDMA channels and the frequency offset between multiple downlink FDMA channels.

[0068] 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, the number of uplink FDMA channels is 2, 4, 8, or 16, as shown in Figure 5. In Figure 5, the bandwidth of the uplink FDMA channels is 1 MHz. In this embodiment, the AMP device can transmit more data through up to 16 uplink FDMA channels, or the AMP device can transmit data to more APs.

[0069] In some embodiments, if the AMP device supports uplink FDMA, the maximum number of uplink FDMA channels is 16, if the bandwidth of the uplink FDMA channels is 1 MHz, 2 MHz, 8 MHz, or 16 MHz.

[0070] In some embodiments, if the AMP equipment supports uplink FDMA, and the bandwidth of the uplink FDMA channels is 250 kHz, the maximum number of uplink FDMA channels is 20.

[0071] Specifically, the maximum number of different uplink FDMA channels can apply to different regions / countries. For example, in some regions / countries, the available uplink FDMA channel bandwidths are 1MHz, 2MHz, 8MHz, or 16MHz, in which case the maximum number of uplink FDMA channels could be 16. As another example, in some regions / countries, the available uplink FDMA channel bandwidth is 250kHz, in which case the maximum number of uplink FDMA channels could be 20.

[0072] In some embodiments, when an 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. Different uplink FDMA channels carry different network device identifiers (IDs).

[0073] In some embodiments, if the AMP device supports uplink FDMA, multiple uplink FDMA channels correspond to a single network device. That is, multiple uplink FDMA channels can address the same network device, allowing the AMP device to upload more uplink data to a single network device at once.

[0074] In some embodiments, when multiple uplink FDMA channels correspond to a single network device, the target uplink FDMA channel among the multiple uplink FDMA channels carries identification information for the network device corresponding to the multiple uplink FDMA channels. Alternatively, the target uplink FDMA channel is the primary uplink FDMA channel among the multiple uplink FDMA channels, or the target uplink FDMA channel is the uplink FDMA channel with the highest or lowest index among the multiple uplink FDMA channels.

[0075] Specifically, for example, as shown in Figure 6, uplink FDMA channels 0 to 4 are used for network device 1, and uplink FDMA channels 5 to 7 are used for network device 2. The IDs of network device 1 and network device 2 may be transported to uplink FDMA channel 0 and uplink FDMA channel 5, respectively, and the data of network device 1 and network device 2 may be transported to uplink FDMA channels 0 to 4 and uplink FDMA channels 5 to 7, respectively.

[0076] In some embodiments, the length of the uplink data to be transmitted is constant, and the uplink data to be transmitted does not occupy all of the uplink FDMA channels, and the portion of the uplink FDMA channels not occupied by the uplink data to be transmitted is filled with zeros. Naturally, the portion of the uplink FDMA channels not occupied by the uplink data to be transmitted may be filled with other information, and the embodiments of this application are not limited thereto.

[0077] In some embodiments, when an AMP device supports uplink FDMA, a correspondence exists between a legacy preamble and an uplink FDMA channel. Alternatively, 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, or one legacy preamble corresponds to multiple uplink FDMA channels.

[0078] In some embodiments, the number of uplink FDMA channels corresponding to a single AMP device is determined based on the bandwidth of the legacy preamble, or the number of uplink FDMA channels corresponding to a single AMP device is defined by the protocol, or the number of uplink FDMA channels corresponding to a single AMP device is set by the network.

[0079] In some embodiments, a 1 MHz legacy preamble can support up to five uplink FDMA channels in the 920-925 MHz bandwidth.

[0080] Specifically, for example, as shown in Figure 7a, a narrower uplink FDMA channel follows one legacy preamble.

[0081] Specifically, as shown in Figure 7b, for example, one legacy preamble is followed by two narrower uplink FDMA channels, with the same number of uplink FDMA channels following each legacy preamble. The uplink FDMA channels addressing a single network device may or may not be constrained by the bandwidth of the legacy preamble.

[0082] Specifically, for example, as shown in Figure 7c, one legacy preamble may be followed by one or two narrower uplink FDMA channels, some legacy preambles may be followed by one narrower uplink FDMA channel, some legacy preambles may be followed by two narrower uplink FDMA channels, and the number of uplink FDMA channels following the legacy preamble may vary. The uplink FDMA channels addressing a single network device may or may not be constrained by the bandwidth of the legacy preamble.

[0083] In some embodiments, when an AMP device supports downlink FDMA, the number of downlink FDMA channels is 2m, where m is a positive integer. For example, when an AMP device supports downlink FDMA, the number of downlink FDMA channels can be 2, 4, 8, or 16, as shown in Figure 8. In Figure 8, the bandwidth of the downlink FDMA channels is 1MHz. In this embodiment, more AMP devices can be addressed via up to 16 downlink FDMA channels, or network devices can transmit more data to the AMP devices.

[0084] In some embodiments, if the AMP device supports downlink FDMA, the maximum number of downlink FDMA channels is 16, where the bandwidth of the downlink FDMA channels is 1 MHz, 2 MHz, 8 MHz, or 16 MHz.

[0085] In some embodiments, if the AMP device supports downlink FDMA, the maximum number of downlink FDMA channels is 20, given that the bandwidth of the downlink FDMA channels is 250 kHz.

[0086] Specifically, the maximum number of different downlink FDMA channels can apply to different regions / countries. For example, in some regions / countries, the supported downlink FDMA channel bandwidths are 1MHz, 2MHz, 8MHz, or 16MHz, in which case the maximum number of downlink FDMA channels could be 16. As another example, in some regions / countries, the supported downlink FDMA channel bandwidth is 250kHz, in which case the maximum number of downlink FDMA channels could be 20.

[0087] In some embodiments, if 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, and different downlink FDMA channels carry identifiers (IDs) of different AMP devices.

[0088] In some embodiments, if 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, and as a result, network equipment (e.g., APs) can transmit more downlink data to a single AMP device at once. In other words, network equipment (e.g., APs) can address more AMP devices simultaneously, which is necessary when deploying AMP devices on a large scale. Also, if there is a large amount of data addressing a single AMP device, the FDMA design also allows the AMP device to receive more data carried by multiple downlink FDMA channels.

[0089] In some embodiments, when multiple downlink FDMA channels correspond to a single AMP device, the target downlink FDMA channel among the multiple downlink FDMA channels carries identification information for the AMP device corresponding to the multiple downlink FDMA channels. Alternatively, the target downlink FDMA channel is the primary downlink FDMA channel among the multiple downlink FDMA channels, or the target downlink FDMA channel is the downlink FDMA channel with the highest or lowest index among the multiple downlink FDMA channels.

[0090] Specifically, for example, as shown in Figure 9, downlink FDMA channels 0 to 4 are used for AMP device 1, and downlink FDMA channels 5 to 7 are used for AMP device 2. The IDs of AMP device 1 and AMP device 2 may be transported to downlink FDMA channel 0 and downlink FDMA channel 5, respectively, and the data of AMP device 1 and AMP device 2 may be transported to downlink FDMA channels 0 to 4 and downlink FDMA channels 5 to 7, respectively.

[0091] In some embodiments, the length of the downlink data to be transmitted is constant, and the downlink data to be transmitted does not occupy all of the downlink FDMA channels among the plurality of downlink FDMA channels, and the portion of the plurality of downlink FDMA channels not occupied by the downlink data to be transmitted is filled with zeros. Naturally, the portion of the plurality of downlink FDMA channels not occupied by the downlink data to be transmitted may be filled with other information, and the embodiments of this application are not limited thereto.

[0092] In some embodiments, if the AMP device supports downlink FDMA, a correspondence exists between a legacy preamble and a downlink FDMA channel. Alternatively, the correspondence between the legacy preamble and the downlink FDMA channel includes at least one of the following: one legacy preamble corresponding to one downlink FDMA channel, and one legacy preamble corresponding to multiple downlink FDMA channels.

[0093] In some embodiments, the number of downlink FDMA channels corresponding to a single AMP device is determined based on the bandwidth of the legacy preamble, or the number of downlink FDMA channels corresponding to a single AMP device is defined by the protocol, or the number of downlink FDMA channels corresponding to a single AMP device is set by the network.

[0094] In some embodiments, a 1 MHz legacy preamble can support up to five downlink FDMA channels in the 920-925 MHz bandwidth.

[0095] Specifically, for example, as shown in Figure 10a, a narrower downlink FDMA channel follows one legacy preamble.

[0096] Specifically, as shown in Figure 10b, for example, one legacy preamble is followed by two narrower downlink FDMA channels, with the same number of downlink FDMA channels following each legacy preamble. The downlink FDMA channels addressing a single AMP device may or may not be constrained by the bandwidth of the legacy preamble.

[0097] Specifically, for example, as shown in Figure 10c, one legacy preamble may be followed by one or two narrower downlink FDMA channels, some legacy preambles may be followed by one narrower downlink FDMA channel, some legacy preambles may be followed by two narrower downlink FDMA channels, and the number of downlink FDMA channels following different legacy preambles may vary. The downlink FDMA channels addressing a single AMP device may or may not be constrained by the bandwidth of the legacy preamble.

[0098] Therefore, in the embodiments of this application, the AMP device can improve its communication performance by negotiating with the network side whether or not the AMP device supports uplink FDMA and / or downlink FDMA before transmission, and by designing uplink FDMA and / or downlink FDMA.

[0099] Specifically, if an AMP device supports downlink FDMA, network equipment (e.g., an AP) can address more AMP devices simultaneously, which is necessary for the large-scale deployment of AMP devices. Also, if there is a large amount of data addressing a single AMP device, the FDMA design allows the AMP device to receive more data carried by multiple channels.
