Description

Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202410914801.2, filed on July 8, 2024, entitled "Communication Method and Communication Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Technology

[0003] With the development of communication technology, the 6 GHz band is the main spectrum resource for the continued expansion of the mid-band. The allocation of this band is still under discussion. One spectrum resource allocation method under discussion is that cellular devices and wireless fidelity (WiFi) devices share the upper half of 6 GHz (U6 GHz). For example, the 6425 to 7125 MHz band in 6 GHz can be allocated to cellular communication and WiFi communication.

[0004] For example, cellular devices and Wi-Fi devices can share spectrum resources using unlicensed spectrum. However, unlicensed spectrum requires cellular devices to undergo a channel access procedure similar to random access before transmitting data, which affects the quality of service (QoS) of the cellular system. Therefore, how to enable cellular devices and Wi-Fi devices to share spectrum resources while prioritizing the QoS of the cellular system has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a communication method that aims to enable cellular devices and WiFi devices to share spectrum resources while prioritizing the QoS of the cellular system.

[0006] Firstly, a communication method is provided. This method can be executed by a first communication device. Unless otherwise specified, the "first communication device" in this application can refer to the first communication device itself, a component within the first communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. For ease of description, the following explanation uses execution by the first communication device as an example.

[0007] The communication method includes: receiving first indication information; determining at least one frequency domain resource based on the first indication information; wherein the first frequency domain resource is used for the first communication device to receive first information and the second communication device to receive second information; the first information is used to schedule time-frequency resources for the first communication device to transmit data, and the second information is used to schedule time-frequency resources for the second communication device to transmit data; wherein the first communication device supports a cellular communication protocol and the second communication device supports a wireless local area network (WLAN) protocol; or, the first communication device supports a WLAN communication protocol and the second communication device supports a cellular communication protocol.

[0008] Based on the above technical solution, the first communication device can determine at least one frequency domain resource based on the received first indication information. The first frequency domain resource is used by the first communication device to receive first information for time-frequency resources for scheduling the transmission of data by the first communication device. The first frequency domain resource can also be used by the second communication device to receive second information for time-frequency resources for scheduling the transmission of data by the second communication device. Therefore, in a coexisting system (i.e., a system that simultaneously has devices supporting cellular communication protocols and devices supporting wireless local area network protocols), both cellular devices and WiFi devices can determine the location for receiving scheduling information based on the first indication information. Under the premise of prioritizing the QoS of the cellular system, the cellular devices and WiFi devices can share spectrum resources.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the first indication information indicates at least one frequency domain resource, including: the first indication information indicates the frequency domain location and bandwidth corresponding to each frequency domain resource in the at least one frequency domain resource.

[0010] Based on the above technical solution, the first indication information can indicate the frequency domain location and bandwidth of a certain frequency domain resource, thereby enabling the device receiving the first indication information to accurately know the frequency domain location and bandwidth of each frequency domain resource based on the first indication information, ensuring the accuracy of determining the frequency domain resource.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the first indication information indicates the frequency domain position corresponding to each frequency domain resource, including: the first indication information indicates the frequency domain start position of each frequency domain resource.

[0012] Based on the above technical solution, since the first indication information can indicate the bandwidth of each frequency domain resource, when the first indication information indicates the frequency domain position of a certain frequency domain resource, it can indicate the frequency domain start position of the frequency domain resource. The device receiving the first indication information can accurately know the position of the frequency domain resource based on the frequency domain start position and bandwidth indicated by the first indication information, which can reduce signaling overhead to a certain extent.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the first indication information indicates the frequency domain start position of each frequency domain resource, including: the first indication information indicates the frequency domain offset value of the frequency domain start position and the reference frequency domain position of each frequency domain resource.

[0014] Based on the above technical solution, the first indication information indicating the frequency domain start position of a certain frequency domain resource can be a frequency domain offset value indicating the frequency domain start position of the frequency domain resource and the reference frequency domain position, or the first indication information can directly indicate the frequency domain start position of the frequency domain resource. That is, the first indication information can indicate the frequency domain start position of a certain frequency domain resource through different indication methods, thereby improving the flexibility of the solution.

[0015] In conjunction with the first aspect, in certain implementations of the first aspect, if the first communication device is a terminal device supporting a cellular communication protocol and the second communication device is a station (STA) or access point (AP) supporting a wireless local area network protocol, then receiving the first indication information includes: receiving a first message from a first network device, the first message including the first indication information, and the first network device supporting a cellular communication protocol; or, if the first communication device is a terminal device or a first network device supporting a cellular communication protocol and the second communication device is a station (STA) supporting a wireless local area network protocol, then receiving the first indication information includes: receiving a second message from a second network device, the second message including the first indication information, and the second network device supporting a wireless local area network protocol; or, if the first communication device is a first network device supporting a cellular communication protocol and the second communication device is a second network device supporting a wireless local area network protocol, then receiving the first indication information includes: receiving the first indication information from a server.

[0016] Based on the above technical solutions, the first communication device can receive the first indication information in the following ways: 1) If the first communication device is a cellular terminal device and the second communication device is a WiFi device, the first indication information can be broadcast by the cellular base station and transmitted using a coexistence signaling format that can be parsed by both the cellular device and the WiFi device; 2) If the first communication device is a cellular terminal device, the first indication information can be indicated by the cellular base station. For example, a partial bandwidth (BWP) mechanism can be used, that is, the first frequency domain resource is regarded as a BWP specifically for coexistence scheduling and activated by DCI indication. The first indication information can be understood as the DCI that activates the BWP; 3) If the first communication device is a WiFi network device or a cellular network device, the first indication information can be received through a non-air interface method (such as through an automatic frequency coordination (AFC) server); 4) If the first communication device is a cellular device (e.g., a cellular terminal device or a cellular network device) and the second communication device is a STA, the first indication information can be sent by the AP.

[0017] In summary, there are multiple ways for the first communication device to receive the first instruction information, which improves the flexibility of the solution.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, when the first indication information indicates multiple frequency domain resources, the first frequency domain resource carries second indication information, the second indication information being used to indicate a second frequency domain resource, the method further comprising: determining, based on the second indication information, that the second frequency domain resource is used by the first communication device to receive the first information and / or the second communication device to receive the second information, wherein the second frequency domain resource is one of the multiple frequency domain resources other than the first frequency domain resource.

[0019] Based on the above technical solution, when the first indication information indicates multiple frequency domain resources, a switching instruction can be added to the activated first frequency domain resource to achieve dynamic switching. For example, the first frequency domain resource carries second indication information, which is used to indicate a second frequency domain resource among the multiple frequency domain resources. The first communication device can determine, based on the second indication information, that the second frequency domain resource is used for the first communication device to receive the first information and / or for the second communication device to receive the second information.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the first indication information includes first sub-information, the first sub-information being used to indicate time-frequency resources carrying third indication information, the third indication information being used to indicate at least one frequency domain resource.

[0021] Based on the above technical solution, the first indication information carries the first sub-information indicating the time-frequency resource carrying the third indication information. That is, the first indication information does not need to actually carry information indicating at least one frequency domain resource respectively. Instead, the third indication information indicates at least one frequency domain resource, thereby reducing the load of the first indication information.

[0022] Secondly, a communication method is provided. This method can be executed by a network device. Unless otherwise specified, "network device" in this application can refer to the network device itself, a component within the network device (e.g., a processor, chip, or chip system), or a logical module or software capable of implementing all or part of the functions of the network device. For ease of description, the following explanation uses execution by a network device as an example.

[0023] The communication method includes: generating first indication information, the first indication information being used to indicate at least one frequency domain resource, wherein the first frequency domain resource is used for a first communication device to receive first information and a second communication device to receive second information, the first information being used to schedule time-frequency resources for the first communication device to transmit data, and the second information being used to schedule time-frequency resources for the second communication device to transmit data; and sending the first indication information, wherein the first communication device supports a cellular communication protocol and the second communication device supports a wireless local area network protocol; or, the first communication device supports a wireless local area network communication protocol and the second communication device supports a cellular communication protocol.

[0024] In conjunction with the second aspect, in some implementations of the second aspect, the first indication information indicates at least one frequency domain resource, including: the first indication information indicates the frequency domain location and bandwidth corresponding to each frequency domain resource in the at least one frequency domain resource.

[0025] In conjunction with the second aspect, in some implementations of the second aspect, the first indication information indicates the frequency domain position corresponding to each frequency domain resource, including: the first indication information indicates the frequency domain start position of each frequency domain resource.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, the first indication information indicates the frequency domain start position of each frequency domain resource, including: the first indication information indicates the frequency domain offset value of the frequency domain start position and the reference frequency domain position of each frequency domain resource.

[0027] In conjunction with the second aspect, in some implementations of the second aspect, if the first communication device is a terminal device supporting a cellular communication protocol and the second communication device is a station (STA) or access point (AP) supporting a wireless local area network (WLAN) protocol, then the network device is a first network device supporting a cellular communication protocol; or, if the first communication device is a terminal device or a first network device supporting a cellular communication protocol and the second communication device is a station (STA) supporting a WLAN protocol, then the network device is a second network device supporting a WLAN protocol; or, if the first communication device is a first network device supporting a cellular communication protocol and the second communication device is a second network device supporting a WLAN protocol, then the network device is a server.

[0028] In conjunction with the second aspect, in some implementations of the second aspect, when the first indication information indicates multiple frequency domain resources, the first frequency domain resource carries the second indication information, which is used to indicate a second frequency domain resource, wherein the second frequency domain resource is one of the multiple frequency domain resources other than the first frequency domain resource.

[0029] In conjunction with the second aspect, in some implementations of the second aspect, the first indication information includes a preamble and a first sub-information, wherein the preamble is used for time synchronization between the first communication device and the second communication device, the first sub-information is used to indicate time-frequency resources carrying third indication information, and the third indication information is used to indicate at least one frequency domain resource.

[0058] To facilitate understanding of the embodiments of this application, the following points will be explained first.

[0059] First, in this application, "for indicating" can include both direct and indirect indication. When describing an indication message as indicating A, it can include whether the indication message directly indicates A or indirectly indicates A, but does not necessarily mean that the indication message carries A.

[0060] The information indicated by the instruction is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. At the same time, common parts of various pieces of information can be identified and indicated uniformly to reduce the instruction overhead caused by individually indicating the same information.

[0061] Second, in this application, "at least one" refers to one or more, and "more than one" refers to two or more (including two). Furthermore, in the embodiments of this application, "first," "second," and various numerical designations (e.g., "#1," "#2," etc.) are merely for descriptive convenience and are not intended to limit the scope of the embodiments of this application. The sequence numbers of the processes below do not imply the order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application. It should be understood that the objects described in this way can be interchanged where appropriate to describe solutions other than those in the embodiments of this application. Moreover, in the embodiments of this application, terms such as "S410" are merely identifiers for descriptive convenience and do not limit the order of execution steps.

[0062] Third, in the embodiments of this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0063] Fourth, the term "storage" in the embodiments of this application can refer to storage in one or more memories. These memories can be separate installations or integrated into an encoder, decoder, processor, or communication device. Alternatively, some memories can be separately installed, while others can be integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this.

[0064] Fifth, in the implementation of this application, "protocol" may refer to standard protocols in the field of communications, such as the NR protocol and related protocols applied in future communication systems, and this application does not limit it.

[0065] Sixth, in the embodiments of this application, the terms "of", "corresponding (relevant)", "corresponding", and "associate" can sometimes be used interchangeably. It should be noted that when their differences are not emphasized, their intended meanings are consistent.

[0066] Seventh, in the embodiments of this application, "under the circumstances", "when", and "if" can sometimes be used interchangeably. It should be noted that when the distinction is not emphasized, their intended meanings are consistent.

[0067] Eighth, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0068] Ninth, in this article, "message", "information", or "information element (IE)" can be used interchangeably. There are no restrictions on the name of the message or information, as long as it can achieve the corresponding function.

[0069] Tenth, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, and "send information" can include direct transmission or indirect transmission through other units or modules. "Receive information from YY" can be understood as the source of the information being YY, and "receive information" can include direct reception from YY or indirect reception from YY through other units or modules. Besides air interface transmission or reception signals implemented at the system level, such as network devices or terminal devices, "send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. For example, a modem or system-on-a-chip (SoC) chip or system-in-package (SIP) chip transmits or receives signals. "Send" or "receive" can also be performed through device components, for example, by using buses, traces, or interfaces to transmit or receive signals through several parts, modules, or chips of a device.

[0070] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0071] The technical solutions of this application embodiment can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) systems or new radio (NR) systems and future communication systems, vehicle-to-other devices (V2X), where V2X can include vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), etc., Long Term Evolution-V (LTE-V) technology for vehicle-to-everything (V2X), vehicle-to-everything (V2X), machine-type communication (MTC), and Internet of Things (IoT). Things (IoT), Long Term Evolution of Machines (LTE-M), Machine to Machine (M2M), Wireless Local Area Network (WLAN), etc.

[0072] Figure 1 is a schematic diagram of a communication system applicable to this application. As shown in Figure 1, the communication system 100 includes at least one network device, such as network device 111, network device 112, and network device 113 shown in Figure 1. The wireless communication system may also include at least one terminal device, such as terminal device 121, terminal device 122, terminal device 123, terminal device 124, terminal device 125, terminal device 126, and terminal device 127 shown in Figure 1.

[0073] As one possible implementation, the communication system shown in Figure 1 can be a communication system that conforms to the requirements of the 3rd Generation Partnership Project (3GPP) standard, referred to as a 3GPP network. 3GPP networks typically include, but are not limited to, 5G networks, 4th-generation (4G) mobile communication networks, and other future communication systems. In this implementation, the network equipment and terminal equipment can be communication devices within the 3GPP network.

[0074] For example, in this implementation, network devices and terminal devices can communicate with each other, including but not limited to: multi-site transmission, enhanced mobile broadband (eMBB) transmission, etc., wherein network devices 112 and 113 as shown in FIG1 can transmit with terminal device 124 through multi-site transmission, and network device 112 as shown in FIG1 can transmit with terminal devices 121, 122 and 123 through eMBB transmission.

[0075] For example, in this implementation, network devices can also communicate with each other, including but not limited to: backhaul. As shown in FIG1, network device 111 and network device 112 can communicate through backhaul, and network device 111 and network device 113 can also communicate through backhaul. In this case, network device 112 and network device 113 can act as relay nodes in the system.

[0076] For example, in this implementation, terminal devices can also communicate with each other, including but not limited to: device-to-device (D2D) transmission, as shown in FIG1, terminal device 122 can communicate with terminal device 125 through D2D transmission.

[0077] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities to terminal devices. Network devices can be cellular systems related to the 3rd Generation Partnership Project (3GPP), such as 5G mobile communication systems, or future-oriented evolution systems. Network devices can also be open radio access networks (O-RAN or ORAN), cloud radio access networks (CRAN), or wireless fidelity (WiFi) systems. For example, the network device can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB) in a 5G mobile communication system, a 3GPP subsequent evolution base station, a transmission reception point (TRP), an access node, a wireless relay node, or a wireless backhaul node in a WiFi system. In communication systems employing different radio access technologies (RATs), the names of devices with base station capabilities may differ. For example, in an LTE system, it may be called an eNB or eNodeB, and in a 5G or NR system, it may be called a gNB. This application does not limit the specific name of the base station. The network equipment may include one or more co-located or non-co-located transmitting and receiving points. Furthermore, the network equipment may include at least one of the following: one or more central units (CUs), one or more distributed units (DUs), and one or more radio units (RUs).

[0078] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU (open DU), CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. Exemplarily, the function of CU can be implemented by one entity or different entities. For example, the function of CU can be further divided, that is, the control plane and user plane can be separated and implemented through different entities, namely the control plane CU entity (i.e., the CU-CP entity) and the user plane CU entity (i.e., the CU-UP entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the function of the access network device. For example, the CU (Complex Unit) is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU (Digital Unit) is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. This allows multiple network function entities to implement some of the functions of a radio access network device. These network function entities can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). Network devices can also include active antenna units (AAUs). The AAU implements some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It is understood that network devices can be one or more of the following: CU nodes, DU nodes, and AAU nodes. Furthermore, a CU can be classified as a network device in the RAN, or it can be classified as a network device in the core network (CN); this application does not limit this classification.For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU). Multiple access network devices in the communication system can be base stations of the same type or different types. Base stations can communicate with terminal devices, or they can communicate with terminal devices through relay stations. In this embodiment, the device used to implement the network device function can be the network device itself, or a device that supports the network device in implementing that function, such as a chip system or a combination of devices or components that can implement the access network device function. This device can be installed in the network device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0079] A terminal device is a user-side device with wireless transceiver capabilities. It can be a fixed device, mobile device, handheld device (e.g., mobile phone), wearable device, in-vehicle device, or a wireless device (e.g., communication module, modem, or chip system) built into the aforementioned devices. Terminal devices are used to connect people, objects, and machines, and can be widely used in various scenarios, such as: cellular communication, D2D communication, V2X communication, machine-to-machine / machine-type communications (M2M / MTC), the Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, drones, robots, etc. For example, a terminal device can be a handheld terminal in cellular communication, a communication device in D2D, an IoT device in MTC, a surveillance camera in smart transportation and smart cities, or a communication device on a drone. Terminal equipment is sometimes referred to as user equipment (UE), user terminal, user device, user unit, user station, terminal, access terminal, access station, UE station, remote station, mobile device, or wireless communication device, etc. Terminal equipment can also be a terminal device in an IoT system. IoT is an important component of future information technology development. Its main technical characteristic is connecting objects to networks through communication technology, thereby realizing an intelligent network of human-machine interconnection and machine-to-machine interconnection. In the embodiments of this application, IoT technology can achieve massive connectivity, deep coverage, and terminal power saving through, for example, narrowband (NB) technology. In the embodiments of this application, the device used to implement the functions of the terminal equipment can be the terminal equipment itself, or it can be a device that supports the terminal equipment in implementing the functions, such as a chip system or a combination of devices or components that can implement the functions of the terminal equipment. This device can be installed in the terminal equipment. The terminal typically contains a communication module, circuit, or chip (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip) that performs the corresponding communication functions. The terminal can also be configured with program instructions for performing corresponding communication functions.

[0080] As another possible implementation, the communication system shown in Figure 1 can be a communication system that conforms to the requirements of the Wireless Local Area Network (WLAN) standard, referred to as a WLAN network. WLAN networks typically include, but are not limited to, Bluetooth, ZigBee, Ultra Wideband, IrDA infrared connectivity (infrared), HomeRF, and support for Institute of Electrical and Electronics Engineers (IEEE) 802.11 related standards, such as 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, and the IEEE 802.11ax next-generation WiFi protocol. In this implementation, network devices and terminal devices can be communication devices within the WLAN network.

[0081] For example, in this implementation, the network device described above can be an access point (AP). An access point can be a node that allows a terminal (e.g., a mobile phone) to access a wired (or wireless) network. It is mainly deployed in homes, buildings, and campuses, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. The access point acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0082] For example, in this implementation, the terminal device can facilitate data communication between stations (STAs). A station can be a non-access point station (non-AP STA), simply referred to as a non-AP station or STA. Specifically, the access point can be a terminal or network device equipped with a WiFi chip. This network device can be a server, router, switch, bridge, computer, mobile phone, relay station, vehicle-mounted equipment, wearable device, network equipment in a 5G network, network equipment in future communication networks, or network equipment in a public land mobile network (PLMN), etc., and this application embodiment is not limited to these categories. The access point can be a device that supports the WiFi standard. For example, access points can also support one or more standards from the IEEE 802.11 series, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, 802.11ay, 802.11bn, and 802.11bf.

[0083] For example, in this implementation, the non-AP site can be a wireless communication chip, wireless sensor, or wireless communication terminal, etc., and can also be referred to as a user, user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. The non-AP site can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, IoT device, wearable device, terminal device in a 5G network, terminal device in a future communication network, or terminal device in a PLMN, etc., and this application embodiment is not limited in this regard. The non-AP site can be a device that supports the WLAN standard. For example, non-AP sites can support one or more standards in the IEEE 802.11 series, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, 802.11ay, and 802.11bf.

[0084] For example, non-AP sites can be mobile phones, tablets, set-top boxes, smart TVs, smart wearable devices, vehicle communication devices, computers, Internet of Things (IoT) nodes, sensors, smart home devices such as smart cameras, smart remote controls, smart water and electricity meters, and sensors in smart cities.

[0085] The aforementioned AP or non-AP sites may include transmitters, receivers, memory, processors, etc., wherein the transmitter and receiver are used for transmitting and receiving packet structures, respectively, the memory is used for storing signaling information and pre-agreed preset values, etc., and the processor is used for parsing signaling information and processing related data, etc.

[0086] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0087] For example, the communication system 100 may further include an application function (AF) network element, which is a control plane network function provided by the operator's network for providing application layer information; the communication system 100 may also include a session management function (SMF) network element, which is a control plane network function provided by the operator's network. In this embodiment, when the communication system 100 includes both AF and SMF network elements, the AF can send service-related information to the network device through the SMF.

[0088] To facilitate understanding of the embodiments of this application, the basic concepts involved in this application will be explained first.

[0089] 1. 6GHz band: As the main spectrum resource for the continued expansion of the mid-band, the allocation method for the 6GHz band is still under discussion.

[0090] For example, the allocation methods for the 6GHz band include, but are not limited to:

[0091] 1) Allocate the entire 6GHz band to WiFi;

[0092] 2) Allocate 5925-6425MHz of the 6GHz band to WiFi, and allocate the remaining 6425-7125MHz (which can be called U6G) to international mobile telecommunications (IMT). IMT can also be called cellular communication. In the following text, IMT and cellular communication can be used interchangeably.

[0093] 3) All or part of the U6G frequency band will be allocated for IMT, and the allocation of the remaining frequency band is not yet clear.

[0094] 4) Cellular and WiFi sharing U6G.

[0095] For example, cellular and WiFi sharing of U6G includes, but is not limited to, the following two types of sharing schemes:

[0096] ① Unlicensed spectrum technology: Cellular devices meet the basic requirements of unlicensed frequency bands during operation. While retaining the cellular frame structure, they can realize the functions of traditional unlicensed frequency band devices, such as listen before talk (LBT) and clear channel assessment (CCA).

[0097] ② Based on coexistence signal interoperability scheme: Potential implementation methods for coexistence signals include, but are not limited to, the following two:

[0098] As one possible implementation, cellular devices can implement WiFi signal formats, or WiFi devices can implement cellular signal formats, enabling interoperability between cellular devices and WiFi devices.

[0099] As another possible implementation, a new coexistence signal format is introduced, enabling both cellular and WiFi devices to resolve the coexistence signal.

[0100] 2. Unlicensed spectrum technology: This technology enables cellular devices and WiFi devices to share spectrum resources. Specifically, cellular devices undergo a channel access process similar to random access before transmitting, as shown in Figure 2. Based on the different usage scenarios of spectrum resources, they can be divided into the following two main categories:

[0101] Type 1: Also known as, it is mainly used to initiate a channel occupancy time (COT). The process of initiating a COT is shown in Figure 3.

[0102] Type 2: Primarily used for multiple transmissions within the same COT segment. Depending on the transmission interval, Type 2 channel access is further divided into three different subtypes: Type 2A is mainly used for transmission intervals of 25µs; Type 2B is mainly used for transmission intervals of 16µs; and Type 2C is mainly used for transmission intervals less than 16µs.

[0103] 3. Coexistence-based signal resource sharing scheme: This scheme introduces signaling that both cellular and WiFi devices can detect or decode, thereby reducing conflicts and interference between the two systems. The core idea is to detect or decode cross-technology signaling, allowing each device to self-authorize access to the shared medium. For example:

[0104] • Wi-Fi devices identify cellular signals and then use possible interference avoidance mechanisms.

[0105] Cellular devices identify WiFi signals and then use possible interference avoidance mechanisms.

[0106] 4. Coexistence signal (CS): The coexistence signal format is a signal format that both cellular devices and WiFi devices can parse. This application does not impose any limitations on the coexistence signal format; it can be a WiFi signal format implemented by the aforementioned cellular device, a cellular signal format implemented by the WiFi device, or a new coexistence signal format introduced, etc.

[0107] The above text, in conjunction with Figure 1, briefly introduces the scenarios in which the communication method provided in the embodiments of this application can be applied, as well as the basic concepts that may be involved in the embodiments of this application. In the basic concepts, it introduces the current discussion on the allocation method of 6GHz band spectrum resources. One such method is that cellular devices and WiFi devices share a portion of the 6GHz band (e.g., cellular and WiFi share U6G).

[0108] For example, cellular devices and WiFi devices can share spectrum resources through unlicensed spectrum or by designing coexisting signals. However, the aforementioned unlicensed spectrum technology for sharing a portion of the 6GHz band between cellular devices and WiFi devices presents the following problems:

[0109] 1) Cellular equipment loses its ability to guarantee quality of service (QoS). For example, cellular equipment services experience higher latency.

[0110] 2) There is a possibility of conflicts between resources, which may waste air interface time and frequency resources.

[0111] In order to enable cellular devices and WiFi devices to share spectrum resources while improving the QoS of cellular systems, this application provides a communication method to ensure the QoS of cellular systems.

[0112] The communication method provided in this application can be applied to systems that communicate using multi-antenna technology, such as the communication system 100 shown in FIG1. ​​This communication system may include at least one network device and at least one terminal device.

[0113] The embodiments shown below do not specifically limit the structure of the execution entity of the method provided in the embodiments of this application. As long as communication can be performed according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application. For example, the method provided in the embodiments of this application can be executed by a first communication device. Unless otherwise specified, "first communication device" in this application can refer to the first communication device itself (e.g., network device, terminal device, access point, or station), a component in the first communication device (e.g., processor, chip, or chip system), or a logic module or software that can implement all or part of the functions of the first communication device. As another example, the method provided in the embodiments of this application can be executed by a second communication device. Unless otherwise specified, "second communication device" in this application can refer to the second communication device itself (e.g., network device, station, access point, or terminal device), a component in the second communication device (e.g., processor, chip, or chip system), or a logic module or software that can implement all or part of the functions of the second communication device.

[0114] In this application, the first communication device supports cellular communication protocols (e.g., 5G or future communication standards), and the second communication device supports wireless local area network protocols (e.g., WiFi 7 or future WiFi standards); or, the first communication device supports wireless local area network communication protocols, and the second communication device supports cellular communication protocols, that is, the communication standards supported by the first communication device and the second communication device are different.

[0115] By way of example and not limitation, the first communication device may be a terminal device or a first network device that supports cellular communication protocols. For example, the first communication device may be a user-side device with wireless transceiver capabilities in the RAN described above, such as a UE; or, for example, the first communication device may be a device in the RAN system described above that provides wireless communication capabilities for terminal devices, such as a gNB.

[0116] As an example and not a limitation, the first communication device can be a STA (Standard Interface Device) or a second network device that supports wireless LAN communication protocols. For example, the first communication device can be a user-side device with wireless transceiver capabilities in the WLAN system described above, such as a STA; or, for another example, the first communication device can be a node in the WLAN system described above where a terminal (e.g., a mobile phone) enters a wired (or wireless) network, such as an AP (Access Point).

[0117] Similarly, the second communication device can also be the aforementioned terminal device, the first network device, the STA, or the second network device, which will not be elaborated here.

[0118] The specific forms of the first and second communication devices described above are merely examples and do not constitute any limitation on the scope of protection of this application. In this application, the first and second communication devices may support different communication standards. For example, the first communication device may support a first communication protocol, and the second communication device may support a second communication protocol. The first and second communication protocols may be different, and examples will not be given here.

[0119] For ease of description, the following explanation will use the example of the first communication protocol being a cellular communication protocol and the second communication protocol being a wireless LAN communication protocol; or the first communication protocol being a wireless LAN communication protocol and the second communication protocol being a cellular communication protocol. If the first and second communication devices support other communication standards, the description of cases where the first communication device supports a cellular communication protocol and the second communication device supports a wireless LAN protocol, or the first communication device supports a wireless LAN communication protocol and the second communication device supports a cellular communication protocol, will not be repeated.

[0120] Figure 4 is a schematic flowchart of a communication method provided in an embodiment of this application, including the following steps:

[0121] S410, the first communication device receives the first instruction information from the network device, and correspondingly, the network device sends the first instruction information to the first communication device.

[0122] Specifically, the first indication information is used to indicate at least one frequency domain resource, wherein the first frequency domain resource is used by the first communication device to receive first information and by the second communication device to receive second information. The first information is used to schedule the time-frequency resources for the first communication device to transmit data, and the second information is used to schedule the time-frequency resources for the second communication device to transmit data.

[0123] It should be understood that at least one frequency domain resource mentioned above can also be predefined by the protocol; the method of protocol predefinition will not be elaborated upon. The following section details how to use at least one frequency domain resource through the first indication information.

[0124] As an example and not a limitation, the first and second information mentioned above can be the same information or different information. For example, the first and second information can be the same information, and both the first and second communication devices can receive it.

[0125] Optionally, the first frequency domain resources can also be used for the first communication device to feed back first interference information to the third communication device, and / or, can also be used for the second communication device to feed back second interference information to the fourth communication device. Wherein, the third communication device supports a cellular communication protocol, and the fourth communication device supports a wireless local area network (WLAN) protocol; or, the third communication device supports a WLAN communication protocol, and the fourth communication device supports a cellular communication protocol.

[0126] The first frequency domain resources mentioned above can be used for the first communication device to receive first information or report first interference information, and for the second communication device to receive second information or report second interference information. These are just examples and do not constitute any limitation on the scope of protection of this application. The first frequency domain resources can also be used for the transmission of other signaling, which will not be illustrated here.

[0127] For example, the first indication information indicates at least one frequency domain resource, including:

[0128] The first indication information indicates the frequency domain location and bandwidth corresponding to each frequency domain resource in at least one frequency domain resource. Optionally, the bandwidth size corresponding to a certain frequency domain resource can be predefined by the protocol. When the bandwidth size corresponding to a certain frequency domain resource is predefined by the protocol, the first indication information may not indicate the bandwidth of that frequency domain resource.

[0129] For example, the above-mentioned at least one frequency domain resource includes a first frequency domain resource, a second frequency domain resource, and a third frequency domain resource. The first indication information is used to indicate the corresponding frequency domain position #1 and bandwidth #1 of the first frequency domain resource, the corresponding frequency domain position #2 and bandwidth #2 of the second frequency domain resource, and the corresponding frequency domain position #3 and bandwidth #3 of the third frequency domain resource.

[0130] For example, the frequency domain location corresponding to a certain frequency domain resource can be identified by Δf, and the bandwidth corresponding to a certain frequency domain resource can be identified by f. cs Logo.

[0131] To facilitate understanding, the possible signaling format of the first indication information is briefly described below with reference to Figure 5. As shown in Figure 5, the first indication information can indicate the frequency domain location and bandwidth corresponding to n frequency domain resources, as shown in Figure 5. The first indication information for frequency domain resource #1 (Δf, f...) cs ), frequency domain resource #2 (Δf,f cs ), frequency domain resource #3 (Δf,f cs ), ... frequency domain resources #n of (Δf,f cs ).

[0132] Optionally, the first indication information indicates the frequency domain position corresponding to each frequency domain resource, including: the first indication information indicates the frequency domain start position of each frequency domain resource.

[0133] For example, the first indication information can be implemented by indicating the frequency domain start position of each frequency domain resource by a frequency domain offset value that indicates the frequency domain start position and the reference frequency domain position of each frequency domain resource.

[0134] As shown in Figure 6, the first indication information indicates Δf for frequency domain resource #1, where Δf is the frequency domain offset value between the frequency domain start position and the reference frequency domain position of frequency domain resource #1. Additionally, the first indication information also indicates f for frequency domain resource #1. cs Thus, the first communication device can determine frequency domain resource #1 based on the first indication information.

[0135] Figure 6 illustrates the frequency domain location and bandwidth of a certain frequency domain resource using the first indication information as an example. The way the first indication information indicates a frequency domain resource does not constitute any limitation on the scope of protection of this application. The first indication information can also be used to indicate other frequency domain resources. The way the first indication information indicates a frequency domain resource can be referred to, which will not be elaborated here.

[0136] By way of example and not limitation, the reference frequency domain location in this application may be a reference frequency point of a shared frequency band predefined by the protocol, wherein the shared frequency band may be the intersection of the frequency domain range that can be used to transmit coexistence signals as defined by the cellular communication protocol and the frequency domain range that can be used to transmit coexistence signals as defined by the second communication protocol; or, the shared frequency band may be a frequency domain range predefined by the protocol.

[0137] For example, a cellular communication protocol defines a frequency range #1 that can be used to transmit coexistence signals. This frequency range #1 is greater than or equal to a first frequency point and less than or equal to a second frequency point. A second communication protocol defines a frequency range #2 that can be used to transmit coexistence signals. This frequency range #2 is greater than or equal to a third frequency point and less than or equal to a fourth frequency point. The shared frequency band can be the intersection of frequency range #1 and frequency range #2. For example, if the coexistence frequency band is greater than or equal to a fifth frequency point and less than or equal to a sixth frequency point, then the fifth frequency point is greater than or equal to the maximum value between the first and third frequency points, and the sixth frequency point is less than or equal to the minimum value between the second and fourth frequency points.

[0138] By way of example and not limitation, the reference frequency domain location in this application may be the starting frequency point of the frequency domain resource for receiving the first indication information.

[0139] In addition, the first indication information can also indicate the frequency domain offset value of a frequency domain resource by using an identifier that indicates the frequency domain offset value of the frequency domain resource; and / or, the first indication information can indicate the bandwidth of a frequency domain resource by using an identifier that indicates the bandwidth of the frequency domain resource.

[0140] For example, if the identifier of the frequency domain offset value and the frequency domain offset value satisfy the correspondence shown in Table 1a or Table 1b below, then a certain frequency domain offset value can be indicated by the identifier indicating the frequency domain offset value.

[0141] Table 1a

[0142] As shown in Table 1a above, when the frequency offset between the frequency domain start position and the reference frequency domain position of frequency domain resource #1 is 2RB, the first indication information can achieve the purpose of indicating the frequency domain start position of frequency domain resource #1 by indicating the identifier "11" of 2RB.

[0143] Table 1b

[0144] Tables 1a and 1b above are merely examples and do not constitute any limitation on the scope of protection of this application. The correspondence between frequency domain offset values ​​and frequency domain offset value identifiers can also be reflected in other forms besides tables (e.g., formulas), which will not be illustrated here.

[0145] For example, if the bandwidth identifier and bandwidth satisfy the correspondence shown in Table 2a or Table 2b below, then a certain bandwidth can be indicated by the bandwidth identifier.

[0146] Table 2a

[0147] As shown in Table 2a above, when the bandwidth of frequency domain resource #1 is 2RB, the first indication information can indicate the bandwidth of frequency domain resource #1 by indicating the identifier "01" of 2RB.

[0148] Table 2b

[0149] Tables 2a and 2b above are merely examples and do not constitute any limitation on the scope of protection of this application. The correspondence between bandwidth and bandwidth identifier can also be reflected in other forms besides tables (e.g., formulas), which will not be illustrated here.

[0150] For example, in this application, the first communication device receives the first indication information in several possible ways, including but not limited to the following:

[0151] Method 1: The information received by the first communication device and the second communication device indicating at least one frequency domain resource is the same. For example, both the first communication device and the second communication device receive the first indication information.

[0152] As one possible implementation, if the first communication device is a terminal device that supports cellular communication protocols and the second communication device is a STA or AP that supports wireless local area network protocols, then the first communication device and the second communication device can receive first instruction information from the first network device that supports cellular communication protocols.

[0153] In this implementation, the first network device can broadcast first indication information to cellular terminal devices and WiFi devices (e.g., STAs and / or APs). For example, this first indication information employs a coexistence signal design that can be decoded by both the first and second communication devices.

[0154] As an example and not a limitation, in this implementation, the signaling format of the first indication information can be fixed, the frequency can be fixed, and the time can be repeated periodically, such as the period T of the first indication information. g As stipulated in the agreement.

[0155] To facilitate understanding, Figure 7 will be used to briefly describe how the first network device sends the first instruction information under this implementation method.

[0156] As shown in Figure 7, the first indication information can be carried on a time-frequency resource in the coexisting frequency band (the time-frequency resource filled with diagonal lines as shown in Figure 7). The first indication information indicates at least one frequency domain resource, including frequency domain resource #1 shown in Figure 7 (the frequency domain resource corresponding to the time-frequency resource filled with square lines as shown in Figure 7). Furthermore, frequency domain resource #1 is used for the first communication device to receive first information and the second communication device to receive second information. For example, the time-frequency resource for the first communication device to transmit data according to the first information can be the time-frequency resource filled with black as shown in Figure 7, and the time-frequency resource for the second communication device to transmit data according to the second information can also be the time-frequency resource filled with black as shown in Figure 7. As an example, the periodically transmitted first indication information can schedule different frequency domain resources. For instance, the frequency domain resource #1 scheduled by the first indication information in Figure 7 and the frequency domain resource #2 scheduled by the first indication information in the next period can be different frequency domain resources.

[0157] The time-frequency resources carrying the first indication information, the frequency domain resources indicated by the first indication information, and the time-frequency resources for scheduling the first and second information shown in Figure 7 are merely examples and do not constitute any limitation on the scope of protection of this application.

[0158] As another possible implementation, if the first communication device is a terminal device or a first network device that supports cellular communication protocols, and the second communication device is a STA that supports wireless local area network protocols, then the first communication device and the second communication device can receive first instruction information from the second network device that supports wireless local area network protocols.

[0159] In this implementation, the second network device can send first indication information to the cellular terminal device or cellular network device, as well as the STA. For example, the first indication information employs a coexistence signal design that can be decoded by both the first and second communication devices.

[0160] In this implementation, the method by which the second network device sends the first instruction information can be referred to the description of the first network device sending the first instruction above, and will not be repeated here.

[0161] As another possible implementation, if the first communication device is a first network device that supports cellular communication protocols and the second communication device is a second network device that supports wireless local area network protocols, then the first communication device and the second communication device can receive first instruction information from the server.

[0162] In this implementation, the server can send the first instruction information to the first communication device and the second communication device via a non-air interface method (e.g., wired method).

[0163] Method 2: The first communication device and the second communication device independently receive the same information indicating at least one frequency domain resource. For example, the first communication device receives the first indication information, while the second communication device receives the first indication information #1, which indicates the same frequency domain resource as the first indication information.

[0164] As one possible implementation, if the first communication device is a terminal device that supports cellular communication protocols, then the first communication device can receive first instruction information from a first network device that supports cellular communication protocols.

[0165] In this implementation, if a terminal device that supports cellular communication protocols establishes a connection with the first network device through an authorized frequency band, the first network device can also use the existing RRC connection to indicate the location of at least one frequency domain resource.

[0166] For example, the first network device indicates the location of at least one frequency domain resource to the first communication device via RRC signaling, and the aforementioned first indication information can be understood as RRC signaling.

[0167] To facilitate understanding, Figure 8 will be used to briefly describe how the first network device sends the first instruction information under this implementation method.

[0168] As shown in Figure 8, the first indication information can be carried in the licensed frequency band (the time-frequency resource filled with diagonal lines as shown in Figure 8), and the first indication information indicates at least one frequency domain resource including frequency domain resource #1 shown in Figure 8 (the frequency domain resource corresponding to the time-frequency resource filled with square lines as shown in Figure 8).

[0169] As another possible implementation, if the first communication device is a terminal device that supports cellular communication protocols, the first communication device can use the existing partial bandwidth (BWP) mechanism to obtain the first indication information.

[0170] In this implementation, at least one frequency domain resource indicated by the first indication information is used as a spectrum sharing BWP (SS-BWP) specifically for coexistence scheduling and is activated by DCI indication.

[0171] In this implementation, the first instruction information mentioned above can be understood as activating the DCI of SS-BWP.

[0172] As another possible implementation, if the first communication device supports the wireless local area network communication protocol, the first communication device can receive the first indication information in a non-air interface manner (e.g., receive the first indication information through a wired connection to the AFC server).

[0173] The above-mentioned implementation methods are merely illustrative of how the first communication device receives the first instruction information in this application, and do not constitute any limitation on the scope of protection of this application. Other methods of receiving the first instruction information are also within the scope of protection of this application, and will not be illustrated here.

[0174] Furthermore, after receiving the first indication information in this embodiment, the first communication device can determine the frequency domain resources used to receive the first information based on the first indication information. Therefore, the method flow shown in Figure 4 further includes:

[0175] S420, the first communication device determines at least one frequency domain resource based on the first instruction information.

[0176] As an example and not a limitation, when the first indication information indicates multiple frequency domain resources, the frequency domain resource used to receive the first information can also be switched among the multiple frequency domain resources. For example, if the first frequency domain resource carries second indication information, and the second indication information is used to indicate a second frequency domain resource, then the first communication device can determine, based on the second indication information, that the second frequency domain resource is used by the first communication device to receive the first information and / or by the second communication device to receive the second information. Here, the second frequency domain resource is one of the multiple frequency domain resources other than the first frequency domain resource, and the second indication information can be referred to as handover signaling.

[0177] Optionally, the aforementioned first frequency domain resource is a default active frequency domain resource among at least one frequency domain resource. For example, the protocol may stipulate that the first (Δf,f) in the first indication information is activated by default. cs The frequency domain resources corresponding to the ) field can transmit the first information within those frequency domain resources.

[0178] For example, a second indication information can be added to the activated frequency domain resources to achieve fast dynamic switching. One implementation is to define a switching sequence specifically for indicating switching, with different switching sequences corresponding to different frequency domain resources. For example, at least one frequency domain resource can be numbered sequentially according to its starting frequency point from smallest to largest, corresponding one-to-one with the switching sequence. If the device detects a switching sequence in the activated frequency domain resources, it switches to the corresponding frequency domain resource.

[0179] To facilitate understanding, Figure 9 will be used to briefly explain how to switch active frequency domain resources. Assume that the first indication information indicates at least one frequency domain resource including frequency domain resource #0 and frequency domain resource #1. To facilitate indication during the switching process, a switching sequence indicating the switching can be defined. For example, switching sequence #0 corresponds to frequency domain resource #0, and switching sequence #1 corresponds to frequency domain resource #1.

[0180] As shown in Figure 9, a handover sequence #0 can be carried on the activated frequency domain resource #1. Therefore, after the device detects the handover sequence #0 in frequency domain resource #1, it switches to frequency domain resource #0 to receive scheduling information. Alternatively, a handover sequence #1 can be carried on the activated frequency domain resource #0. Therefore, after the device detects the handover sequence #1 in frequency domain resource #0, it switches to frequency domain resource #1 to receive scheduling information.

[0181] Optionally, to avoid having too many field payloads in the first indication information, a hierarchical indication method can be adopted. For example, the first indication information includes first sub-information, which indicates time-frequency resource #1. The time-frequency resource #1 carries third indication information, which indicates at least one frequency domain resource. That is, the above-mentioned determination of at least one frequency domain resource based on the first indication information can be understood as: determining the first sub-information based on the first indication information, determining time-frequency resource #1 based on the first sub-information, receiving the third indication information on time-frequency resource #1, and determining at least one frequency domain resource based on the third indication information.

[0182] For example, when it is necessary to indicate the frequency domain location and bandwidth of multiple frequency domain resources, the payload of the first indication information is too large and it is not suitable to put them all in one signaling. The first indication information mentioned above can be divided into two parts: a preamble and an indication first sub-information. The preamble is mainly responsible for synchronization, and the first sub-information indicates the time-frequency resource carrying the third indication information. The third indication information indicates the frequency band location, bandwidth and indication format of at least one frequency domain resource.

[0183] To facilitate understanding, the hierarchical indication method of the first indication information will be briefly introduced with reference to Figure 10.

[0184] As can be seen from Figure 10, the first sub-information in the first indication information indicates the resources occupied by the third indication information (the time-frequency resources filled by the horizontal line in Figure 10), and the third indication information indicates at least one frequency domain resource (frequency domain resource #1 and frequency domain resource #2 in Figure 10).

[0185] Furthermore, as described above, the first information received by the first communication device is used to schedule the time-frequency resources for transmitting data by the first communication device. For example, the first information is carried on a frequency domain resource indicated by the first indication information, and the time-frequency resources scheduled by the first information can be time-frequency resources of different granularities, such as those at the time domain resource unit (TDU) granularity or those at the frequency domain resource unit (FDU) granularity. That is, one frequency domain resource among at least one frequency domain resource indicated by the first indication information can control the entire coexisting frequency band, or multiple frequency domain resources can control different frequency domain resource units (FDUs).

[0186] To facilitate understanding, the possible situations of the time-frequency resources corresponding to the first information scheduling are explained with reference to Figures 11(a) to (c).

[0187] For example, one frequency domain resource can control the entire coexisting frequency band, as shown in Figures 11(a) and (b). The first information received in the first frequency domain resource can be used to schedule the time-frequency resources for transmitting data in the entire coexisting frequency band. The way in which the first information can be used to schedule the time-frequency resources for transmitting data in the entire coexisting frequency band can be at the TDU granularity (as shown in Figure 11(a)) or at the FDU granularity (as shown in Figure 11(b)). Alternatively, multiple frequency domain resources can control different FDUs, as shown in Figure 11(c). The first indication information indicates multiple frequency domain resources (frequency domain resource #1, frequency domain resource #2, ..., frequency domain resource #n shown in Figure 11(c)). The first information received in different frequency domain resources can be used to schedule different FDUs.

[0188] In the communication method shown in Figure 4, the first communication device can determine at least one frequency domain resource based on the received first indication information. The first frequency domain resource is used by the first communication device to receive first information on time-frequency resources for scheduling the transmission of data by the first communication device. The first frequency domain resource can also be used by the second communication device to receive second information on time-frequency resources for scheduling the transmission of data by the second communication device. Therefore, in a coexisting system (i.e., a system in which both devices supporting cellular communication protocols and devices supporting wireless local area network protocols exist), both cellular devices and WiFi devices can determine the location for receiving scheduling information based on the first indication information, thereby enabling cellular devices and WiFi devices to share spectrum resources.

[0189] The sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

Whether a function is implemented in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated modules can be implemented in hardware, software, or a combination of both.

The following description uses the division of functional modules according to each function as an example.

[0197] Figure 12 is an exemplary block diagram of the communication device 10 provided in an embodiment of this application.

[0198] As shown in Figure 12, for example, the communication device 10 may include a chip system 110, a memory 120, a bus 130, a power management module 140, or a transceiver 150, etc.

[0199] The chip system 110 can be an integrated circuit chip with signal processing capabilities. During implementation, each step of the above method (e.g., S420 in Figure 4) can be completed through the integrated logic circuitry in the hardware of the chip system 110 or through software instructions.

[0200] As an example and not a limitation, chip system 110 may include circuitry or chips responsible for signal processing (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core).

[0201] Optionally, the chip system 110 may also include a memory (such as a cache) for storing instructions and data. In some embodiments, the memory in the chip system 110 is a cache memory. This memory can store instructions or data that the chip system 110 has just used or that are used repeatedly. If the chip system 110 needs to use the instruction or data again, it can directly retrieve it from the memory. This avoids repeated accesses, reduces the waiting time of the chip system 110, and thus improves the efficiency of the system.

[0202] In some embodiments, the chip system 110 may include one or more interfaces. Interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a SIM interface, and / or a USB interface, etc.

In some cases, the code may not be directly executable by the chip system 110, but may instead enable a computer (e.g., at compile and execution time) to perform the functions described in this application. In some cases, memory 120 may in particular contain a basic I / O system that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0205] For example, the chip system 110 executes various functional applications and data processing of the communication device 10 by running instructions stored in the memory 120.

Optionally, the power management module 140 can also supply power to the communication device 10 while charging it (e.g., the battery module of the communication device 10). By way of example and not limitation, the power management module 140 can also supply power to other devices besides the communication device 10.

[0209] Transceiver 150 can communicate bidirectionally via one or more antennas, wired links, or wireless links. For example, transceiver 150 can represent a wireless transceiver and can communicate bidirectionally with another wireless transceiver. Transceiver 150 may also include a modem for modulating packets and providing the modulated packets to the antenna for transmission, and for demodulating packets received from the antenna. Transceiver 150 may include a receiver and a transmitter, the receiver performing the function of receiving information and the transmitter performing the function of transmitting information.

[0210] In some cases, a wireless device may include a single antenna. However, in other cases, the device may have more than one antenna, such as antenna 1 and antenna 2 shown in FIG. 12, which may be capable of simultaneously transmitting or receiving multiple wireless transmissions. Exemplarily, antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in communication device 10 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In other embodiments, the antennas can be used in conjunction with a tuning switch. Communication device 10 can transfer files to other devices via wireless communication functions.

[0211] In one design, the communication device 20 may correspond to the first communication device in the above method embodiments.

[0213] Under this design, the communication device 10 may include modules such as a short-range communication module 164, a sensor 161, a display 162, or a camera 163 as shown in Figure 12.

[0214] The short-range communication module 164 may include modules that support short-range communication, such as WIFI and Bluetooth.

Exemplarily, the communication device 10 implements display functions through a GPU, a display, and an application processor. The GPU is a microprocessor for image processing, connected to the display and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering.

[0221] Baseband unit 210 may include computer-readable medium / memory. Baseband unit 210 is responsible for general processing, including the execution of software stored on the computer-readable medium / memory. When executed by baseband unit 304, the software causes baseband unit 210 to perform the various functions described above. The computer-readable medium / memory may also be used to store data manipulated by baseband unit 210 during software execution.

[0222] The baseband unit 210 further includes a receiving unit 201, a management unit 202, and a transmitting unit 203.

The management unit 202 is used to determine at least one frequency domain resource according to the first indication information.
