[0002] This application claims priority to Chinese Patent Application No. 202410956824.X, filed on July 16, 2024, entitled "A Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of mobile communication technology, and in particular to a communication method and apparatus. Background Technology

[0004] In the rapidly evolving field of wireless communications, the use of unlicensed spectrum is receiving increasing attention, particularly in the 6425 MHz to 7125 MHz band. The coexistence of cellular network systems and Wireless Fidelity (WiFi) network systems in this band presents not only technical challenges but also significant benefits. This coexistence strategy can significantly improve spectrum utilization efficiency, especially given the current scarcity of spectrum resources. Simultaneously, it provides richer and more flexible service options for different types of network users, further promoting innovation and application in wireless communication technologies.

[0005] In scenarios where cellular network systems and WiFi network systems share spectrum, how to rationally allocate the transmission resources of each system is an urgent problem to be solved. Summary of the Invention

[0006] This application provides a communication method and apparatus for allocating transmission resources of any communication system in a scenario where multiple communication systems share the same spectrum.

[0007] In a first aspect, embodiments of this application provide a communication method, which can be executed by a first device. Unless otherwise specified, the "first device" in this application can refer to the first device itself (e.g., a network device such as a base station, access point (AP), or controller), a component within the first device (e.g., a functional module, communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first device. The method includes: the first device determining first information, the first information including the type of a first transmission resource and configuration information of the first transmission resource, the first transmission resource being in a first frequency band, the type of the first transmission resource indicating whether the first transmission resource is a transmission resource of a first communication system or a transmission resource of a second communication system, the first frequency band being a communication frequency band shared by the first communication system and the second communication system, the first communication system being a cellular communication system, and the second communication system being a non-cellular communication system; the first device can also transmit the first information.

[0008] Based on this implementation, the first device can configure transmission resources in a first frequency band shared by the first and second communication systems through first information. These transmission resources can be either those of the first or second communication system. Additionally, the first information may include a type indicator for the transmission resources, specifying whether the transmission resource belongs to the first or second communication system. Based on this first information, the first and second communication systems can use different transmission resources within the first frequency band. Therefore, the transmission resources used by the first and second communication systems can be indicated separately in the coexisting frequency band to improve transmission performance in shared spectrum scenarios. The first communication system can be, for example, a cellular network system, and the second communication system can be, for example, a non-cellular network system such as a WiFi network system.

[0009] In one possible implementation, the first device can transmit the first information via a second transmission resource in the first frequency band, the second transmission resource being different from the first transmission resource.

[0010] Based on this implementation, the first device can send the first information through the transmission resources in the coexisting frequency band. Therefore, the receiving devices of the first communication system and the second communication system can both receive the first information. That is, the first information can be a configuration shared by multiple communication systems, avoiding the need to configure transmission resources separately for each communication system and reducing configuration complexity.

[0011] In one possible implementation, the first information support can be received by devices in the first communication system and the second communication system.

[0012] Based on this implementation, the first information can be received by devices in the first and second communication systems. For example, the first information can be carried on a signal shared by the first and second communication systems.

[0013] In one possible implementation, the configuration information of the first transmission resource includes at least one of the following: frequency domain information of the first transmission resource; time domain information of the first transmission resource.

[0014] Based on this implementation method, the configuration information of the first transmission resource can configure the time and frequency resources of the first transmission resource.

[0015] In one possible implementation, the frequency domain information of the first transmission resource includes at least one of the following: a reference frequency point; the offset between the first transmission resource and the reference frequency point; the bandwidth of the first frequency domain resource; and the time domain information of the first transmission resource includes at least one of the following: the starting time domain position of the first transmission resource; and the time domain length of the first transmission resource.

[0016] In one possible implementation, the first information also includes an index of the first transmission resource.

[0017] Based on this implementation, the index of the first transmission resource can be used to indicate the first transmission resource, improving the efficiency of the indication. For example, when activating the first transmission resource later, the activation indication can include the index of the first transmission resource.

[0018] In one possible implementation, the first information may also include the type of the third transmission resource and the configuration information of the third transmission resource.

[0019] Based on this implementation method, multiple transmission resources in the coexisting frequency band of the first and second communication systems can be configured using the first information, such as the first transmission resource and the third transmission resource, to improve configuration efficiency.

[0020] In one possible implementation, the configuration information of the third transmission resource includes at least one of the following: frequency domain information of the third transmission resource; time domain information of the third transmission resource.

[0023] Based on this implementation method, the first transmission resource can be activated through the second information.

[0024] In one possible implementation, the second information includes at least one of the following: an index of the first transmission resource; frequency domain information of the first transmission resource; and time domain information of the first transmission resource.

[0025] Based on this implementation, the first transmission resource can be indicated by at least one of the index, frequency domain information, or time domain information of the first transmission resource.

[0026] In one possible implementation, the first device may also transmit third information via the first transmission resource, the third information including indication information of the fourth transmission resource.

[0027] Based on this implementation, when the first transmission resource is an active transmission resource, indication information for the fourth transmission resource can be sent through the first transmission resource. For example, this third information can be used to indicate that the fourth transmission resource is an active transmission resource.

[0028] In one possible implementation, the first device may also send fourth information for configuring the second transmission resource.

[0029] Based on this implementation, the first device can configure the second transmission resource through the fourth information to achieve flexible indication of the second transmission resource. The fourth information may include frequency domain information of the second transmission resource and / or time domain information for configuring the second transmission resource; that is, the fourth information can be used to configure the time-frequency position of the second transmission resource. Alternatively, the fourth information can also be switch information, used to indicate whether the second device activates the detection of the first information.

[0030] In one possible implementation, the frequency domain information of the second transmission resource includes at least one of the following: absolute radio frequency channel number; reference frequency point; offset between the second transmission resource and the reference frequency point; bandwidth of the second frequency domain resource; and the time domain information of the second transmission resource includes at least one of the following: starting time domain position of the second transmission resource; and time domain length of the second transmission resource.

The method includes: receiving first information, the first information including the type of a first transmission resource and configuration information of the first transmission resource, the first transmission resource being in a first frequency band, the type of the first transmission resource indicating whether the first transmission resource is a transmission resource of a first communication system or a transmission resource of a second communication system, the first frequency band being a communication frequency band shared by the first communication system and the second communication system, the first communication system being a cellular communication system, and the second communication system being a non-cellular communication system; and transmitting data through the first transmission resource.

[0032] In one possible implementation, the second device can receive the first information through a second transmission resource in the first frequency band, which is different from the first transmission resource.

[0033] In one possible implementation, the first information support can be received by devices in the first communication system and the second communication system.

[0034] In one possible implementation, the configuration information of the first transmission resource includes at least one of the following: frequency domain information of the first transmission resource; time domain information of the first transmission resource.

[0035] In one possible implementation, the frequency domain information of the first transmission resource includes at least one of the following: a reference frequency point; the offset between the first transmission resource and the reference frequency point; the bandwidth of the first frequency domain resource; and the time domain information of the first transmission resource includes at least one of the following: the starting time domain position of the first transmission resource; and the time domain length of the first transmission resource.

[0043] In one possible implementation, the method further includes receiving fourth information for configuring the second transmission resource.

[0044] In one possible implementation, the fourth information includes frequency domain information of the second transmission resource and / or time domain information for configuring the second transmission resource.

[0047] In one alternative implementation, the device may include modules that correspond one-to-one with the methods / operations / steps / actions performed in any possible implementation of any of the first to second aspects. These modules may be hardware circuits, software, or a combination of hardware circuits and software.

[0048] In one optional implementation, the component includes functional modules such as a processing unit (sometimes also called a processing module) and a communication unit (sometimes also called a transceiver module, communication module, etc.). The transceiver unit is capable of both sending and receiving functions. When the transceiver unit performs the sending function, it can be called a sending unit (sometimes also called a sending module); when the transceiver unit performs the receiving function, it can be called a receiving unit (sometimes also called a receiving module). The sending unit and the receiving unit can be the same functional module, which is called the transceiver unit and can perform both sending and receiving functions; alternatively, the sending unit and the receiving unit can be different functional modules, and the transceiver unit is a collective term for these functional modules.

[0049] For example, when the apparatus is used to perform the method described in any one of the first to second aspects, the apparatus may include a communication unit and a processing unit.

[0050] Fourthly, embodiments of this application also provide a communication device, including a processor for executing a computer program (or computer-executable instructions) stored in a memory, such that when the computer program (or computer-executable instructions) is executed, the device performs the method as described in any possible implementation of any of the first to second aspects.

[0074] The specific implementation of this application will be described below with reference to the accompanying drawings in the embodiments of this application.

[0075] The embodiments of this application can be applied to various communication systems, such as cellular systems, such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G, or New Radio (NR), or can be applied to future communication systems or other similar communication systems. For example, communication systems may include non-cellular systems such as Internet of Things (IoT) networks, wireless local area network systems supporting the 802.11 series of protocols, wireless personal area network systems based on ultra-wideband (UWB), sensing systems, vehicle-to-X (V2X) networks, machine-type communication (MTC), long-term evolution-machine (LTE-M), machine-to-machine (M2M), vehicle-to-vehicle (V2V), long-term evolution-vehicle (LTE-V), satellite communication systems, worldwide interoperability for microwave access (WIMAX) communication systems, or WiFi systems. The communication systems described above applicable to the embodiments of this disclosure are merely illustrative examples, and the communication systems applicable to the embodiments of this disclosure are not limited thereto. They are uniformly described here and will not be repeated further below.

[0076] Figure 1 illustrates a possible, non-limiting system diagram. As shown in Figure 1, the communication system 1000 includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one wireless access network device (110a and 110b in Figure 1) and at least one terminal (120a-120j in Figure 1). The terminal connects wirelessly to the wireless access network device, and the wireless access network device connects wirelessly or via a wired connection to the core network. The core network device and the wireless access network device can be independent physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated into the same physical device, or a single physical device can integrate some of the functions of the core network device and some of the functions of the wireless access network device. Terminals can be interconnected with each other, and wireless access network devices can be interconnected via wired or wireless connections. Figure 1 is only a schematic diagram; the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1.

[0077] Radio access network equipment can be a base station (BS), an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access point (AP) in a WiFi system. Radio access network equipment can also be an open RAN (O-RAN or ORAN) or a cloud radio access network (CRAN). Radio access network equipment can also be a communication system integrating two or more of the above systems. Radio access network equipment can be a macro base station (as shown in Figure 1, 110a), a micro base station or an indoor station (as shown in Figure 1, 110b), a relay node, or a donor node, etc.

[0078] Furthermore, the wireless access network equipment can also be a module or unit that performs some of the functions of a base station. For example, it can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. 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, 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. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. 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.

[0079] The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment.

[0080] It is understood that a network device can be referred to as a communication device. For example, a network device can be understood as a device that has network device functions. For example, the device used to implement the functions of a network device can be the network device itself; or some components within the network device, such as CU, DU, or RU. The device used to implement the functions of a network device can also be a device capable of supporting the network device in implementing those functions, such as a chip system, hardware circuitry, software modules, or a combination of hardware circuitry and software modules. This device can be installed in the network device or can be used in conjunction with the network device. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.

[0081] A terminal can also be called a terminal device, UE, STA, mobile station (MS), mobile terminal (MT), etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc.

[0082] The embodiments of this application do not limit the specific technology or device form used in the terminal. It is understood that a terminal can be referred to as a communication device. For example, a terminal can be understood as a device with terminal functions. For example, the device used to implement the terminal functions can be a terminal itself; it can also be a device capable of supporting the terminal in implementing those functions, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in the terminal or can be used in conjunction with the terminal.

[0083] Network devices and terminals can be fixed in location or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the network devices and terminals.

[0084] The roles of network devices and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station or access point (AP). For terminals 120j that access the wireless access network 100 via 120i, drone 120i is a network device; however, for network device 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a network device-to-network device interface protocol. In this case, relative to 110a, 120i is also a network device. Therefore, both network devices and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with network device functions, and 120a-120j in Figure 1 can be called communication devices with terminal functions.

[0085] Unless otherwise specified, wireless access network devices may be referred to as network devices in the following text. As a scenario example, as shown in System A of Figure 2, in a cellular network system, a network device may be, for example, a base station, such as a BS, eNodeB, TRP, or gNB. As shown in System B of Figure 2, in a non-cellular network system, a network device may be, for example, an AP. It is understood that the same physical device can function as a network device in both cellular and non-cellular network systems; for example, a network device may possess the functions of both a base station and an AP.

[0086] As a scenario example, as shown in System A of Figure 2, in a cellular network system, the terminal can be, for example, a UE. As shown in System B of Figure 2, in a non-cellular network system, the terminal can be, for example, a STA. It is understood that the same physical device can function as a terminal in both a cellular network system and a non-cellular network system; for example, a network device can have both UE and STA functions.

[0087] Additionally, network devices may also include controllers. Controllers can be used to forward or transmit signals across multiple network systems. For example, a controller can be used to forward or transmit signals between a cellular network system and a WiFi network system. As shown in system C in Figure 2, a controller can be used to connect a base station in a cellular network system to a STA in a WiFi network system. Specifically, the controller can receive signals transmitted by the base station in the cellular network system and convert them into signals in the WiFi network system; the controller can also transmit signals in the WiFi network system to the STA in the WiFi network system; the controller can also receive signals transmitted by the STA and convert them into signals in the cellular network system; the controller can also transmit signals in the cellular network system to the base station in the cellular network system.

[0088] Furthermore, as shown in system D in Figure 2, the controller can be used for both the access point (AP) in the WiFi network system and the user equipment (UE) in the cellular network system. Specifically, the controller can also receive signals sent by the AP in the WiFi network system and convert them into signals in the cellular network system; the controller can also send signals from the WiFi network system to the UE in the cellular network system; the controller can also receive signals sent by the UE and convert them into signals in the WiFi network system; and the controller can also send signals from the WiFi network system to the base station in the WiFi network system.

[0089] In this application, network devices and terminals can communicate with each other, and terminals can communicate with each other using licensed spectrum, unlicensed spectrum (or unlicensed spectrum), or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0090] Unless otherwise specified in this document, the terms "first device" and "second device" are used to describe the implementing entities. "First device" can be understood as a terminal, a device with terminal functions, or a device that implements terminal functions. For example, the first device is a terminal, or the first device can be a module (e.g., a chip or circuit) within a terminal. Alternatively, "first device" can be understood as a network device, a device with network device functions, or a device that implements network device functions. For example, the first device is a network device, or the second device can be a module (e.g., a chip or circuit) within a network device, or it can be a module or unit (e.g., CU, DU, or RU) that fully or partially implements network device functions, a logic module, or software.

[0091] "Second device" can be understood as a terminal, a device with terminal functions, or a device that implements terminal functions. For example, the second device is a terminal, or the second device can be a module (e.g., a chip or circuit) within a terminal. Alternatively, "second device" can be understood as a network device, a device with network device functions, or a device that implements network device functions. For example, the second device is a network device, or the second device can be a module (e.g., a chip or circuit) within a network device, or it can be a module or unit (e.g., CU, DU, or RU) that fully or partially implements network device functions, a logic module, or software, etc.

[0092] In addition, "first device" can be replaced with "first equipment" or "first communication device", and "second device" can be replaced with "second equipment" or "second communication device".

[0093] In some possible implementation scenarios, the "first device" can be a "terminal," and the "second device" can be a "network device." Alternatively, the "first device" can be a "network device," and the "second device" can be a "terminal." For example, one or more terminals can communicate with the network device separately. In a cellular network system, the interface between the terminal and the network device is a Uu interface.

[0094] 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. Furthermore, "send" can also be understood as the "output" of a chip interface, and "receive" can be understood as the "input" of a chip interface. In other words, "send" or "receive" can occur between devices, such as a base station and a terminal transmitting or receiving data via an air interface. "Send" or "receive" can also occur within a device, such as transmitting or receiving data between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0095] In this application, configuring information via signaling can refer to the configuration of that information between a network device and a terminal via signaling (such as upper-layer signaling). For example, a network device can send configuration signaling to a terminal to configure that information. Alternatively, a terminal can send signaling to a network device to provide configuration or possible configurations for that signaling. Specifically, for cellular networks, the signaling sent between the network device and the terminal can include at least one of radio resource control (RRC) messages, media access control (MAC) control elements (CE), or downlink control information (DCI).

[0096] The information is based on a pre-configured definition, which can refer to network devices and / or terminals obtaining this information based on their local configuration or previously acquired configuration. For example, network devices and / or terminals can obtain this information from their local factory configuration. Specifically, for a given transmission process, the local configuration of the network devices and / or terminals can include configurations obtained and stored locally during previous transmissions via signaling configuration. Alternatively, network devices and / or terminals can obtain this information based on the definition of the relevant communication protocol.

[0097] In this application, "for indicating" can include both direct and indirect indication. When describing "information" for indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.

[0098] In the rapidly evolving field of wireless communications, the use of unlicensed spectrum is receiving increasing attention, particularly in the 6425MHz to 7125MHz band. Spectrum sharing between cellular and non-cellular systems such as Wi-Fi in this band presents not only technical challenges but also significant benefits. This coexistence strategy can significantly improve spectrum utilization efficiency, especially given the current scarcity of spectrum resources. Simultaneously, it provides richer and more flexible service options for different types of network users, further promoting innovation and application in wireless communication technologies.

[0099] With the development of technologies such as 5G NR unlicensed (NR-U), LTE licensed-assisted access (LTE LAA), and automatic frequency coordination (AFC), coexistence schemes between communication technologies in different radio frequency bands have gradually emerged.

[0100] LTE-LAA is a technology that allows LTE networks to utilize unlicensed spectrum, particularly suitable for improving data rates and network coverage at cell edges. Similar to NR-U, LTE-LAA uses the LBT mechanism to ensure the channel is idle before data transmission begins, thus reducing interference with existing Wi-Fi networks. The design of LTE-LAA allows cellular and Wi-Fi networks to coexist more harmoniously in the same frequency band, while improving the user's service experience.

[0101] 5G NR-U is a 5G technology that operates in unlicensed spectrum. It extends the functionality of 5G NR, enabling cellular networks to operate in frequency bands traditionally dominated by other technologies such as Wi-Fi. NR-U utilizes a kill-before-detect (LBT) mechanism similar to LTE-LAA to ensure that cellular operations do not interfere with existing Wi-Fi networks. The NR-U design incorporates optimizations for efficient spectrum utilization, low-latency transmission, and improved network performance in high-density deployment environments.

[0102] AFC (Automatic Frequency Control) is one of the solutions in spectrum management server technology. AFC optimizes frequency usage by WiFi devices in complex electromagnetic environments by dynamically adjusting transmission frequencies to reduce interference and improve spectrum utilization efficiency. AFC helps WiFi devices monitor and adapt to their surrounding wireless environment, dynamically adjusting their frequency settings to avoid conflicts, thus supporting more complex spectrum sharing scenarios.

[0103] Furthermore, 5G NR introduces the concept of bandwidth parts (BWP) to enhance the flexibility and efficiency of spectrum utilization. BWP allows the network to dynamically allocate different spectrum portions based on the current needs of the terminal and channel conditions. This is particularly important for supporting diverse 5G applications, ranging from wide coverage in low-frequency bands to high speeds in high-frequency bands. By using BWP, terminals can operate on a subset of the total carrier bandwidth, thereby optimizing power consumption and improving system performance. For example, under good channel conditions, a wider BWP can be allocated to a terminal to maximize throughput, while under poor conditions, a narrower BWP can be used to maintain a stable connection. The dynamic management and adjustment of BWP helps improve spectrum efficiency and user experience, and is one of the key features that distinguishes 5G NR from previous generations of mobile networks.

[0104] While 5G NR-U, LTE-LAA, spectrum management server technology, and BWP technology provide a technical framework to support the coexistence of multiple wireless technologies in unlicensed frequency bands, several challenges remain in practical deployment. For example, LTE-LAA and 5G NR-U primarily rely on a competition mechanism, resulting in lower access efficiency and impacting the quality of service (QoS) of cellular systems. Spectrum management server technology is mainly applied to WiFi systems. Furthermore, BWP functionality primarily operates within existing NR frequency bands, limiting its scope and configuration flexibility.

[0105] Therefore, in scenarios where cellular network systems and WiFi network systems share spectrum, how to reasonably allocate the transmission resources of each cellular network system and / or WiFi network system is an urgent problem to be solved.

[0106] To address the aforementioned technical problems, embodiments of this application provide a communication method. A first communication system and a second communication system support sharing transmission resources within a first frequency band, which may also be referred to as a coexistence frequency band or a shared frequency band. Furthermore, network devices can configure one or more transmission resources through first information. These one or more transmission resources may include a first transmission resource and may also include a third transmission resource. The first information may also include the type of the transmission resource (or type indication (TI)), used to indicate whether the transmission resource is a transmission resource of the first communication system or the second communication system. The first information may be carried within a second transmission resource in the first frequency band or in other frequency bands outside the first frequency band, without specific limitations. Based on the configuration of the first information, the first communication system and the second communication system can use different transmission resources within the first frequency band. Therefore, the transmission resources used by the first communication system and the second communication system can be indicated (or allocated or configured) in the coexistence frequency band to improve transmission performance in shared spectrum scenarios.

[0107] In this method, the first communication system can represent a cellular network system such as LTE, 5G, or a future communication system, while the second communication system can represent a non-cellular network system such as WiFi. It is also understood that the meanings of the first and second communication systems can vary in practical applications; that is, the embodiments of this application can also be applied to other scenarios. For example, the first and second communication systems can be two different cellular systems (such as LTE and 5G, respectively), or two different non-cellular systems. Furthermore, this application can also be used in scenarios where more than two communication systems share spectrum; that is, the communication method provided in the embodiments of this application can also be implemented in scenarios where at least three communication systems, including the first and second communication systems, share spectrum.

[0108] In this application, the first frequency band may include multiple layered BWPs (spectrum-sharing BWPs, SS-BWPs). SS-BWPs can be divided into SS-BWP#A and SS-BWP#B. SS-BWP#A can be used to carry signals shared by the first and second communication systems (referred to as shared signals or coexistence signals). The first frequency band may contain one or more SS-BWP#Bs, and any SS-BWP#B can be a transmission resource of either the first or second communication system. It can be understood that the first information in this application can be used to configure one or more SS-BWP#Bs, i.e., the first information can be used as an SS-BWP#B configuration (SS-BWP-B-Config). Alternatively, the first transmission resource and the third transmission resource are different SS-BWP#Bs.

[0109] In one possible embodiment, the time-frequency resources of SS-BWP#A and SS-BWP#B do not overlap, that is, the time-domain resources occupied by SS-BWP#A are different from those occupied by SS-BWP#B, and / or, the frequency-domain resources occupied by SS-BWP#A are different from those occupied by SS-BWP#B. As shown in Figure 3, the first frequency band may include multiple SS-BWP#Bs, and the time-frequency resources of SS-BWP#A do not overlap with the time-frequency resources of any one of SS-BWP#Bs.

[0110] The method will be described below with reference to the process shown in Figure 4.

[0111] Figure 4 illustrates an example where the executing entities are a first device and a second device. The first device can be a network device, and the second device can be a terminal. As shown in Figure 2, the first device can be at least one of a base station, an access point (AP), or a controller, and the second device can be at least one of a user interface (UE) or a standby device (STA).

[0112] S101: The first device determines the first information. The first information includes the type of the first transmission resource and the configuration information of the first transmission resource.

[0113] The first transmission resource is located in the first frequency band, which is a communication frequency band shared by the first communication system and the second communication system.

[0114] The first frequency band can be a shared frequency band (or a coexisting frequency band) between the first communication system and the second communication system. In this application, a shared frequency band can refer to a frequency band in which multiple communication systems can both receive and / or transmit signals. For example, the first frequency band is a shared frequency band between a cellular network system and a WiFi network system.

[0115] In one possible embodiment, the first frequency band is an unlicensed frequency band of the first communication system and / or the second communication system. As shown in Figure 3, the first frequency band can be a frequency band other than the licensed frequency band of the cellular network system. Unlicensed frequencies of cellular network systems and WiFi network systems include, for example, the 6425MHz to 7125MHz frequency band, and the first frequency band can include part or all of the 6425MHz to 7125MHz frequency band.

[0116] In other words, the first information can be used to configure transmission resources in the shared frequency band of the first and second communication systems.

[0117] The first transmission resource can be a time-frequency resource in a first frequency band. For example, the first transmission resource can be an SS-BWP#B. The first frequency band can contain one or more SS-BWP#Bs.

[0118] As an example, the transmission resources in the first frequency band can be divided into multiple time-frequency resource units according to certain time-domain and frequency-domain dimensions. Any SS-BWP#B (such as the first transmission resource) can be one of these time-frequency resource units, or it can contain multiple time-frequency resource units. As shown in Figure 5, each time-frequency resource is the minimum scheduling unit (or scheduling unit) of the first communication system and / or the second communication system. The minimum scheduling unit can correspond to a frequency domain unit in the frequency domain and a time domain unit in the time domain. Taking the first communication system as a 5G NR network system as an example, the minimum scheduling unit can be a resource element (RE). Each RE occupies one time slot in the time domain, that is, the time domain unit is a time slot. In addition, each RE occupies one physical resource block (PRB) or resource block (RB) in the frequency domain, that is, the frequency domain unit is a PRB or RB. Among them, the PRB or RB corresponds to one subcarrier in the frequency domain, which can also be said that each RE occupies one subcarrier in the frequency domain. In 5G NR, different transmission resources can correspond to different subcarrier spacings (SCS). For example, in different BWPs, the subcarrier spacing can be different, that is, the REs in different BWPs can correspond to different frequency domain bandwidths.

[0119] For example, if the first frequency band is a coexistence band of cellular network system and WiFi network, the time-frequency resource unit can occupy one frequency data unit (FDU) in the frequency domain and one time data unit (TDU) in the time domain.

[0120] It is understandable that if SS-BWP#B is a transmission resource of the first communication system, then it can have the frame structure of the first communication system. Taking the first communication system as a cellular network system and SS-BWP#B as the scheduling unit represented by number (1) in Figure 5 as an example, the frame structure of SS-BWP#B can contain multiple radio frames, each radio frame can include multiple subframes, and each subframe can include multiple time slots.

[0121] Similarly, if SS-BWP#B is a transmission resource of the second communication system, then SS-BWP#B can have the frame structure of the second communication system. Taking the second communication system as a WiFi network system and SS-BWP#B as the scheduling unit represented by number (2) in Figure 5 as an example, the frame structure of SS-BWP#B can contain multiple physical layer protocol data units (PPDUs). Each PPDU can include legacy short training field (L-STF), legacy long training field (L-STF), legacy signal (L-SIG), high throughput signal (L-SIG), repetitive legacy signal (RL-SIG), and data, etc.

[0122] It is understandable that, given that the frequency and time domain ranges of the first frequency band are known, the time and frequency domain information of each transmission resource unit can be determined.

[0123] As another example, any SS-BWP#B (such as the first transmission resource) can have flexible frequency domain and / or time domain dimensions. As shown in Figure 6, different SS-BWP#Bs can have different frequency domain and / or time domain dimensions, and the first transmission resource can be one of multiple SS-BWP#Bs. In this example, the configuration information of the first transmission resource can be flexibly configured with its frequency domain and / or time domain information to achieve flexible configuration of the time-frequency resources of the first transmission resource. It can be understood that the frequency domain and / or time domain information of the first transmission resource can be configured through its configuration information. For example, the configuration information of the first transmission resource includes its frequency domain and / or time domain information; for details, please refer to the following description of the configuration information of the first transmission resource.

[0124] The following is an introduction to the content of the first piece of information.

[0125] (1) In the first information, the type of the first transmission resource can be used to indicate that the first transmission resource is a transmission resource of a first communication system or a transmission resource of a second communication system. For example, the type of the first transmission resource can be used to indicate that the first transmission resource is a transmission resource of a cellular network system, or the type of the first transmission resource can be used to indicate that the first transmission resource is a transmission resource of a WiFi network system.

[0126] As an example of the type of the first transmission resource, the type of the first transmission resource can occupy 1 bit. When the value of this bit is a first value (such as 0), the type of the first transmission resource can be used to indicate that the first transmission resource is a transmission resource of a first communication system; when the value of this bit is a second value (such as 1), the type of the first transmission resource can be used to indicate that the type of the first transmission resource is a transmission resource of a second communication system. In addition, the first value can also be 1, and the second value can also be 0.

[0127] In another example, the type of the first transmission resource may also include an identifier (or index or field) corresponding to a first communication system or a second communication system. The identifier corresponding to the first communication system can be used to indicate that the first transmission resource is a transmission resource of the first communication system, and the identifier corresponding to the second communication system can be used to indicate that the first transmission resource is a transmission resource of the second communication system. Specifically, the identifier corresponding to the first communication system can be identifier #1, and the identifier corresponding to the second communication system can be identifier #2, where identifier #1 and identifier #2 are different. For example, identifier #1 can be the system identifier of the first communication system, and identifier #2 can be the system identifier of the second communication system. For instance, the system identifier of a cellular network system can be the name of the cellular network, such as LTE or 5G, and the system identifier of a WiFi network system can be WiFi, etc. Alternatively, identifiers for multiple communication systems, including cellular network systems and WiFi network systems, can be pre-configured via signaling or defined based on pre-configuration, such as 0, 1, 2, ..., where identifier #1 can be the identifier of the first communication system, and identifier #2 can be the identifier of the second communication system.

[0128] Therefore, identifier #1 can be used to represent the first communication system, and identifier #2 can be used to represent the second communication system. When the type of the first transmission resource is identifier #1, the type of the first transmission resource can be used to indicate that the type of the first transmission resource is the transmission resource of the first communication system. When the type of the first transmission resource is identifier #2, the type of the first transmission resource can be used to indicate that the type of the first transmission resource is the transmission resource of the second communication system.

[0129] In one possible implementation, in a scenario where multiple SS-BWP#Bs exist in the first frequency band, the multiple SS-BWP#Bs may include an SS-BWP#B that serves as a first transmission resource. Referring to the description of the type of the first transmission resource, the first information may also include the type of at least one transmission resource other than the type of the first transmission resource (such as referred to as a third transmission resource) to indicate whether the third transmission resource is a transmission resource of the first communication system or a transmission resource of the second communication system.

[0130] For example, the first information includes type indications for some or all of the multiple SS-BWP#Bs. These type indications can indicate that the corresponding SS-BWP#B is a transmission resource of a first communication system or a second communication system. Some or all of the multiple SS-BWP#Bs can include first and / or third transmission resources. For instance, as shown in Figure 7, the first information can contain type indications for all SS-BWP#Bs. Each SS-BWP#B's type indication is 1 bit. When the 1-bit type indication has a first value, it indicates that the corresponding SS-BWP#B is a transmission resource of the first communication system; when the 1-bit type indication has a second value, it indicates that the corresponding SS-BWP#B is a transmission resource of the second communication system. It can be understood that in Figure 7, TI = 0 indicates that the type indication in the first information has a first value, and TI = 1 indicates that the type indication in the first information has a second value.

[0131] For example, the first information may only contain type indications for SS-BWP#Bs that serve as transmission resources for the first communication system. These type indications can indicate that these (or this) SS-BWP#Bs are transmission resources for the first communication system. The SS-BWP#Bs serving as transmission resources for the first communication system may include first transmission resources and / or third transmission resources. For instance, the 1-bit type indication may always take the first value, indicating that the corresponding SS-BWP#B is a transmission resource for the first communication system. Alternatively, in this implementation, the first information may not contain type indications for SS-BWP#Bs that serve as transmission resources for the second communication system. The second device can determine, based on the 1-bit type indication, which identifies the SS-BWP#Bs serving as transmission resources for the first communication system, and then determine that other SS-BWP#Bs in the first frequency band are transmission resources for the second communication system.

[0132] Alternatively, the first information may only include a type indication of SS-BWP#Bs that serve as transmission resources for the second communication system. This type indication can specify that these (or this) SS-BWP#Bs are transmission resources for the second communication system. The SS-BWP#Bs serving as transmission resources for the second communication system may include first and / or third transmission resources. For example, the 1-bit type indication may always take the second value, indicating that the corresponding SS-BWP#B is a transmission resource for the second communication system. In another implementation, the first information may not include a type indication of SS-BWP#Bs serving as transmission resources for the first communication system. The second device can determine, based on the 1-bit type indication, which identifies SS-BWP#Bs serving as transmission resources for the second communication system, and then determine that other SS-BWP#Bs in the first frequency band are transmission resources for the first communication system.

[0133] (2) In the first information, the configuration information of the first transmission resource can be used to configure the first transmission resource.

[0134] Specifically, the configuration information of the first transmission resource can be used to determine or indicate the frequency domain information and / or time domain information of the first transmission resource.

[0135] In one possible embodiment, the frequency domain information and / or time domain information used to determine or indicate the first transmission resource may refer to the configuration information of the first transmission resource including resource information of the first transmission resource. The resource information may include frequency domain information and / or time domain information.

[0136] The frequency domain information of the first transmission resource may include at least one of the following: reference frequency information of the first transmission resource, offset between the first transmission resource and the reference frequency, or bandwidth of the first frequency domain resource.

[0137] The following sections will explain the reference frequency information, the offset between the first transmission resource and the reference frequency, or the bandwidth of the first frequency domain resource.

[0138] (1) Reference frequency information, also known as reference frequency or reference frequency domain position, can refer to the frequency of a reference point in the frequency domain. For example, a reference frequency point can be defined as point C. For instance, reference frequency information may include the absolute radio frequency channel number (ARFCN) of point C. Furthermore, when the frequency range of the first frequency band or the frequency range of the coexisting frequency band of the first and second communication systems is known, the reference frequency information may include the offset between point C and the high-frequency or low-frequency boundary of the frequency range of the first frequency band or the coexisting frequency band of the first and second communication systems. For example, if the offset between point C and the low-frequency boundary of the coexisting frequency band is 0, meaning point C is the low-frequency boundary of the coexisting frequency band, and the reference frequency information is used to indicate the offset between point C and the low-frequency boundary of the coexisting frequency band, then the reference frequency information can be set to 0. Alternatively, if point C is located at a higher frequency than the low-frequency boundary of the coexisting frequency band, and the reference frequency information is used to indicate the offset between point C and the low-frequency boundary of the coexisting frequency band, the reference frequency information can be set to a value greater than 0. For example, point C is located at a lower frequency position on the high frequency boundary of the coexisting frequency band, and the reference frequency information is used to indicate the offset between point C and the high frequency boundary of the coexisting frequency band. The reference frequency information can be set to a value greater than 0.

[0139] (2) The offset between the first transmission resource and the reference frequency point can be used to determine the frequency domain difference (or frequency domain offset) between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency point. Therefore, the second device can determine the frequency domain difference based on the offset, and determine the high-frequency boundary or low-frequency boundary of the first transmission resource based on the frequency domain difference and the reference frequency point. Here, the reference frequency point can be point C or point A. Point A can be a common reference point of the resource block grid. The meaning and determination method of point A can be referred to the relevant description in 3GPP protocol 38.211-4.4.4.2. For example, in the downlink of the primary cell (PCell), the offset between point A and point A represents the frequency offset between point A and the lowest subcarrier of the lowest resource block of the synchronization signal and physical broadcast channel (PBCH) block (SSB) used by the terminal for initial cell selection.

[0140] As an example, the offset between the first transmission resource and the reference frequency point can indicate Among them, the frequency domain difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency point, And the bandwidth can satisfy a functional relationship, the second device can then use this functional relationship... Furthermore, by setting the bandwidth and determining the offset between the first transmission resource and the reference frequency, the high-frequency boundary or low-frequency boundary of the first transmission resource can be determined. (See Figure 8.) It can be used to determine the frequency domain difference between a reference frequency point (point C in the figure) and the high-frequency boundary or low-frequency boundary (low-frequency boundary in the figure) of the first transmission resource.

[0141] For example, the frequency domain difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency point is... The set bandwidth is times that of the previous setting. This is understandable. The multiple may simply be an example of a functional relationship, such as the frequency domain difference. Furthermore, other functional relationships can also be satisfied between the set bandwidths, without specific limitations. These functional relationships can be configured via signaling or defined through pre-configuration.

[0142] For cellular networks, a frequency unit can be a PRB or RB, etc. Alternatively, it can be an FDU, etc., without specific limitations. For example, the bandwidth of a frequency unit can be related to the communication system by default. For instance, when the first communication system is a cellular network system, the frequency unit can be determined to be a PRB. Furthermore, the bandwidth of a frequency unit can be configured through signaling or based on pre-configuration. For example, by pre-configuring through signaling or based on pre-configuration, the first and / or second devices can determine the bandwidth of the frequency unit, or determine that the frequency unit is a PRB, thus knowing the bandwidth of the PRB.

[0143] In one possible implementation, the offset between the first transmission resource and the reference frequency point can be configured as follows: This indicates the phase difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency. The set bandwidth is doubled. Taking the set bandwidth as the bandwidth of the frequency unit as an example, when the first communication system is a cellular network system, the frequency unit is PRB, then... This can represent the number of PRBs, in which case the offset between the first transmission resource and the reference frequency can be configured as follows: This indicates the phase difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency. The frequency domain difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency point is 1 PRB. The bandwidth of PRB is twice that of PRB.

[0144] In another possible implementation, the offset between the first transmission resource and the reference frequency point can also be configured to be equal to... Numerical values ​​with a functional relationship. For example, the offset between the first transmission resource and the reference frequency point can be configured as N, where N is related to... satisfy Equal functional relationships. With For example, the high-frequency boundary or low-frequency boundary of the first transmission resource differs from the reference frequency by 2. N The bandwidth is set multiple times. This functional relationship is configured via signaling or based on a pre-defined configuration.

[0145] In another possible implementation, the offset between the first transmission resource and the reference frequency point can also be configured as follows: The index in the set of candidate values. Taking the bandwidth as an example where the bandwidth is the bandwidth of a frequency unit, the set of candidate values ​​is {2, 4, 8, 32, 128}, where, if... If the value is 32, then the offset between the first transmission resource and the reference frequency can be configured to be 4, where 32 is the fourth value in the aforementioned set. This configuration of the offset between the first transmission resource and the reference frequency can indicate that the high-frequency boundary or low-frequency boundary of the first transmission resource differs from the reference frequency by 32 frequency units. The bandwidth of the frequency unit can be a default setting or can be related to the communication system.

[0146] It is understandable that the set of alternative values ​​can be pre-configured via signaling or based on pre-configuration definitions.

[0147] In another possible implementation, if the bandwidth is set to the bandwidth of a frequency unit, the offset between the first transmission resource and the reference frequency point can be configured as follows: And information about the frequency unit. This information can indicate the type or bandwidth of the frequency unit. For example, if the information for the frequency unit is "PRBs," it means the frequency unit is a PRB.

[0148] For example, the offset between the first transmission resource and the reference frequency point can be configured as follows: This indicates that the high-frequency boundary or low-frequency boundary of the first transmission resource differs from the reference frequency by 100 PRBs. Alternatively, the offset between the first transmission resource and the reference frequency can be configured as follows: This indicates that the high-frequency boundary or low-frequency boundary of the first transmission resource differs from the reference frequency by 100 FDUs.

[0149] Similarly, the offset between the first transmission resource and the reference frequency can also be configured as follows: The information on the indices and frequency units in the candidate numerical set will not be elaborated further.

[0150] It is understandable that, in addition to configuring the reference frequency point and offset value, the frequency domain information can also include the frequency location information of the first transmission resource, which can indicate the frequency of the high-frequency boundary or the low-frequency boundary.

[0151] (3) The bandwidth of the first frequency domain resource represents the size of the bandwidth occupied by the first transmission resource.

[0152] As an example, the bandwidth of a first frequency domain resource can indicate the bandwidth size. Among them, the bandwidth of the first frequency domain resources, And the bandwidth settings can satisfy a functional relationship. As shown in Figure 8. It can be used to determine the amount of bandwidth occupied by the first transmission resource.

[0153] For example, the bandwidth of the first frequency domain resource is... The set bandwidth is times that of the previous setting. This is understandable. The multiple, or merely an example of a functional relationship, refers to the bandwidth of the first frequency domain resource. Other functional relationships can also be satisfied between the set bandwidth and the bandwidth, without specific limitations. This functional relationship can be configured via signaling or defined via pre-configuration.

[0154] The bandwidth setting can be found in the description of the bandwidth setting related to the offset between the first transmission resource and the reference frequency point. The bandwidth setting can be the same or different for the offset between the first transmission resource and the reference frequency point and the bandwidth of the first frequency domain resource, and no specific requirements are made.

[0155] Optionally, the bandwidth can be the bandwidth of a frequency unit, or it can be other bandwidths defined through signaling configuration or pre-configuration. The bandwidth of a frequency unit can be related to the communication system by default. For example, when the first communication system is a cellular network system, the frequency unit can be determined as a PRB. Alternatively, the bandwidth of a frequency unit can be configured through signaling or based on pre-configuration definitions.

[0156] In the bandwidth of the first frequency domain resources, For instructions, please refer to The description of the indication method. For example, the bandwidth of the first frequency domain resource can be configured as follows: For example, the bandwidth of the first frequency domain resource can be configured to be the same as... The indicator is the numerical value N' that satisfies the functional relationship, for example, Satisfying N' This functional relationship can be configured via signaling or defined via configuration. For example, the bandwidth of the first frequency domain resource can include... The index in the candidate set of values ​​can be found by referring to... Index indication in the candidate set of values The implementation method. In addition, the bandwidth of the first frequency resource also includes information about the frequency unit.

[0157] Taking the setting of bandwidth as frequency bandwidth as an example, the bandwidth configuration of the first frequency domain resource is as follows: This can be interpreted as the bandwidth occupied by the first transmission resource being 10 PRBs; the bandwidth configuration of the first frequency domain resource is as follows. This can be interpreted as the bandwidth occupied by the first transmission resource being 20 FDUs.

[0158] The time-domain information of the first transmission resource may include the starting time-domain position and / or time-domain length of the first transmission resource.

[0159] The starting time domain location and time domain length are explained below.

[0160] (1) The starting time domain position of the first transmission resource may refer to the starting time of the first transmission resource in the time domain, or it may refer to the time interval between the starting position of the first transmission resource and the time domain resource occupied by the first information.

[0161] For example, the starting time domain position of the first transmission resource can be configured as follows: As shown in Figure 8 It can be used to indicate the time interval between the starting position of the first transmission resource and the time domain resource occupied by the first information. The unit can be an absolute duration (such as milliseconds) or the duration of a time-domain unit of the first communication system and / or the second communication system. For example, in the case where the first transmission resource is a transmission resource of the first communication system, the starting time-domain position of the first transmission resource is configured as follows: This indicates that the first transmission resource starts at time slot number 50, or that the starting position of the first transmission resource is 50 time slots after the transmission resource occupied by the first information.

[0162] For example, the starting time domain position of the first transmission resource can be configured to be the same as... "Number N that satisfies the functional relationship", for example, Accordingly, the first transmission resource is labeled 2 N” The time slot is used as the starting time domain position, or the starting position of the first transmission resource is 2 seconds after the transmission resource occupied by the first information. N” Each time slot.

[0163] For example, the starting time domain position of the first transmission resource can be configured from the set of candidate values. For the index, please refer to [link / reference]. Index indication in the candidate set of values The implementation method. The set of candidate values ​​can contain... The set of alternative values ​​can be pre-configured via signaling or based on a pre-defined configuration.

[0164] (2) The time domain length of the first transmission resource can refer to the amount of time occupied by the first transmission resource.

[0165] For example, the starting time domain position of the first transmission resource can be configured as follows: As shown in Figure 8 It can be used to determine the duration of the first transmission resource. The unit can be an absolute duration (such as milliseconds) or the duration of a time-domain unit of the first communication system and / or the second communication system. For example, in the case where the first transmission resource is the transmission resource of the first communication system, This indicates that the first transmission resource occupies 32 time slots.

[0166] For example, the starting time domain position of the first transmission resource can be configured to be the same as... Numerical values ​​N”' that satisfy a functional relationship, for example, Correspondingly, the first transmission resource occupies 2 N”’ Each time slot.

[0167] For example, the starting time domain position of the first transmission resource can be configured from the set of candidate values. For the index, please refer to [link / reference]. Index indication in the candidate set of values The implementation method. The set of candidate values ​​can contain... The set of alternative values ​​can be pre-configured via signaling or based on a pre-defined configuration.

[0168] In addition, the configuration information of the first transmission resource may also include other information besides resource information that can be used to determine the resource information of the first transmission resource. For example, the configuration information of the first transmission resource may include the index of the time-frequency resource unit occupied by the first transmission resource. For example, in the example of Figure 5, the configuration information of the first transmission resource may include the index of the time-frequency resource unit occupied by the first transmission resource. For example, all time-frequency resource units in the first frequency band can be numbered, and the configuration information of the first transmission resource may include the number of the occupied time-frequency resource unit. The numbering rules include, for example, assigning time-frequency resource unit numbers sequentially from 0 (or 1) in descending order of frequency, or assigning time-frequency resource unit numbers sequentially from 0 (or 1) in ascending order of frequency.

[0169] Since the time-frequency position of each time-frequency resource unit in this example is fixed, the time-frequency resource unit occupied by the first transmission resource can be determined based on the number. In other words, in this example, the configuration information of the first transmission resource does not need to carry the complete time-domain and / or frequency-domain information of the first transmission resource, but rather carries the index of the time-frequency resource unit occupied by the first transmission resource. Accordingly, the second device can determine the time-domain and / or frequency-domain information of the first transmission resource based on the index of the time-frequency resource unit occupied by the first transmission resource, thus reducing indication overhead.

[0170] In one possible embodiment, the configuration information or first information of the first transmission resource may further include an index of the first transmission resource and / or a parameter set (numerology) of the first transmission resource.

[0171] The index of the first transmission resource can be used to identify the first transmission resource. For example, in a scenario where multiple SS-BWP#Bs exist in the first frequency band, each SS-BWP#B can correspond to its own index, meaning multiple SS-BWP#B indices can be assigned. In this application, the index corresponding to any SS-BWP#B can be referred to as the index of the assigned SS-BWP#B. For an SS-BWP#B with an assigned index, the index can be used to indicate the activated SS-BWP#B subsequently. For example, when activating an SS-BWP#B, the index can be used to indicate the activated SS-BWP#B.

[0172] As an example, the index allocation rules may include, for multiple SS-BWP#Bs at the same time domain location, allocating the index of SS-BWP#Bs sequentially from 0 (or 1) in descending order of frequency, or, allocating the index of SS-BWP#Bs sequentially from 0 (or 1) in ascending order of frequency.

[0173] Alternatively, an index can be allocated independently only for SS-BWP#B in the unified communication system. For example, for multiple SS-BWP#B in the first communication system, the index is allocated sequentially increasing from 0 (or 1), and the index is also allocated sequentially increasing from 0 (or 1) for multiple SS-BWP#B in the first communication system.

[0174] It is understandable that the index of the first transmission resource can also be independent of the first information, that is, the index of the first transmission resource can be carried in other signaling or messages other than the first information, in order to reduce the configuration overhead in the coexisting frequency band.

[0175] For example, the first device transmits first information through a coexisting frequency band, the first information including the type and configuration information of multiple SS-BWP#Bs. In addition, the first device or other network devices may also transmit the index of the SS-BWP#B of the first communication system through the traditional frequency band of the first communication system, and / or, the first device or other network devices may also transmit the index of the SS-BWP#B of the second communication system through the traditional frequency band of the second communication system.

[0176] Taking the first communication system as an example, a new field can be added to the BWP indication in the traditional frequency band of the first communication system to carry the index of the allocated SS-BWP#B. Alternatively, the index of the allocated SS-BWP#B can also be carried through new signaling (or messages or fields). New signaling includes, for example, SS-BWP#B index (SS-BWP-B-Index) or SS-BWP set (SS-BWP-B-set). Taking the first communication system as an example, the new signaling can be carried in RRC messages, MAC CE, or DCI messages passing through the traditional frequency band. Taking the SS-BWP-B-Index field carrying the index of the allocated SS-BWP#B as an example, the SS-BWP#B index field can carry the index of each SS-BWP#B, for example, SS-BWP-B-Index = {SS-BWP#B Index i, SS-BWP#B Index j, ..., SS-BWP#B Index k}. Where i, j, ..., k are the indices of each SS-BWP#B, and each index corresponds sequentially to the multiple SS-BWP#Bs configured in the first information. Optionally, the SS-BWP#B index field can also correspond to a time-domain resource. For example, this field carries time-domain information to indicate that the configured index is the index of multiple SS-BWP#Bs occupying this time-frequency resource.

[0177] For example, the first device or other network devices can also send the index of SS-BWP#B in other time domains after the active SS-BWP#B in the coexisting frequency band through the active SS-BWP#B. For instance, an SS-BWP#B index field can be sent through an SS-BWP#B active at a certain time domain location to indicate the index of multiple SS-BWP#Bs at the next time domain location. This SS-BWP#B index field can be carried in the BWP indication, or in signaling such as RRC messages, MAC CE, or DCI; this application does not impose any specific limitations.

[0178] Optionally, when the first transmission resource is a transmission resource of a first communication system, the parameter set of the first transmission resource can be a first parameter set; when the first transmission resource is a transmission resource of a second communication system, the parameter set of the first transmission resource can be a second parameter set. The first parameter set and the second parameter set can be different. For example, the first parameter set can be a parameter set adapted for a cellular network system, and the second parameter set can be a parameter set adapted for a WiFi network system.

[0179] The parameter set of the first transmission resource may include parameters such as the subcarrier spacing, cyclic prefix length, or symbol length of the first transmission resource. It is understood that the first information may also carry parameters such as the subcarrier spacing, cyclic prefix length, or symbol length, without carrying the parameter set.

[0180] In one possible embodiment, the configuration information of the first transmission resource includes first configuration information and second configuration information. The first configuration information includes the common configuration of the first transmission resource, and the second configuration information includes the dedicated configuration of the first transmission resource. Alternatively, the configuration information of the first transmission resource can be described as including both the common and dedicated configurations.

[0181] The first configuration information and the second configuration information can be transmitted independently. For example, the first configuration information and the second configuration information can be carried on different transmission resources in the second frequency band. The first configuration information and the second configuration information can be carried on different transmission resources in the first frequency band or the second frequency band. The second frequency band can be a frequency band supported by the first communication system or the second communication system. Specifically, if the first transmission resource is a transmission resource of the first communication system, then the second frequency band can be a frequency band supported by the first communication system but not supported by the second communication system. For example, the second frequency band can be a licensed frequency band of the first communication system. If the first transmission resource is a transmission resource of the second communication system, then the second frequency band can be a frequency band supported by the second communication system but not supported by the first communication system. For example, the second frequency band can be a licensed frequency band of the second communication system.

[0182] In addition, the first configuration information and the second configuration information can have different transmission periods (or signaling periods), etc.

[0183] For ease of distinction, the common configuration of the first transmission resource will be referred to as the first common configuration, and the dedicated configuration of the first transmission resource will be referred to as the first dedicated configuration.

[0184] In this application, public configuration can refer to static or semi-static configuration of transmission resources, while dedicated configuration can refer to dynamic configuration of transmission resources. Alternatively, public configuration can be understood as a configuration shared by multiple terminals or transmission resources, while dedicated configuration can be a configuration specific to a single terminal or transmission resource.

[0185] As an implementation approach, configurations that are not frequently updated in different SS-BWP#Bs and / or can be applied to multiple receivers can be used as common configurations to reduce the overhead of duplicate indications.

[0186] The following text uses the first common configuration as an example to introduce the common configurations of transmission resources. That is to say, other common configurations can be described with reference to the description of the first common configuration.

[0187] As an example, the first common configuration may include at least one of the following parameters: a parameter set, subcarrier spacing (in units such as kilohertz (kHz)), cyclic prefix length (in units such as microseconds (μs)), reference frequency information, or symbol length. The parameter set can be considered to include the subcarrier spacing, cyclic prefix length, or symbol length. Therefore, it can also be said that the first common configuration includes a parameter set and / or reference frequency information. Alternatively, the first common configuration may carry parameters such as subcarrier spacing, cyclic prefix length, or symbol length without carrying a parameter set.

[0188] Optionally, when the first transmission resource is a transmission resource of a cellular network system, the parameter set of the first transmission resource can be a first parameter set; when the first transmission resource is a transmission resource of a non-cellular network, the parameter set of the first transmission resource can be a second parameter set, wherein the first parameter set and the second parameter set can be different.

[0189] It is understood that reference frequency information can be used to indicate the frequency domain location of the first transmission resource. Reference frequency information can also be carried in the first dedicated configuration. The reference frequency information will be explained in conjunction with the first dedicated configuration below, and will not be elaborated upon here.

[0190] In this application, the first common configuration can be carried in the BWP indication, or in other words, the first information can be included or carried in the BWP indication. For example, a new field can be added to the BWP indication to carry the common configuration. The new field could be, for example, the SS-BWP#B common configuration (SS-BWP-B-CommonConfig) field. As an example of the SS-BWP-B-CommonConfig field, SS-BWP-B-CommonConfig can be configured as {SCS=15kHz, CP=4.7μs, PointC=6425MHz,…}, indicating a subcarrier spacing of 15kHz, a cyclic prefix length of 4.7μs, and a point C frequency domain position of 6425MHz.

[0191] In addition to being carried in the BWP indication, the first common configuration can also be carried in newly added signaling. The newly added signaling may be, for example, called SS-BWP-CommonConfig signaling. The newly added signaling can be carried via at least one of RRC messages, MAC CE, or DCI. Furthermore, the newly added signaling can be carried in the traditional frequency band of the first communication system, or in a coexisting frequency band of the first frequency band, or in other words, it can be carried in a coexistence signal.

[0192] In addition, the first dedicated configuration may include time-domain information and / or frequency-domain information of the first transmission resource. The time-domain and frequency-domain information of the first transmission resource can be referred to in the description of S101, and will not be repeated here.

[0193] In this application, the first dedicated configuration can be carried in a BWP instruction; in other words, the first information can be included or carried in the BWP instruction. For example, a new field can be added to the BWP instruction to carry the dedicated configuration. The new field could be, for example, the SS-BWP#B dedicated configuration (SS-BWP-B-DedicatedConfig) field. As an example of the SS-BWP-DedicatedConfig field, S-BWP-B-DedicatedConfig can be configured as follows:

[0194] In addition to being carried in the BWP indication, the first dedicated configuration can also be carried in newly added signaling. This newly added signaling may be, for example, called SS-BWP-B-DedicatedConfig signaling. Taking a cellular network system as an example, the newly added signaling can be carried in at least one of the following: RRC message, MAC CE, or DCI. Furthermore, the newly added signaling can be carried in the traditional frequency band of the first communication system, or in a coexisting frequency band of the first frequency band, or in other words, it can be carried in a coexisting signal.

[0195] In one possible embodiment, the first information may include multiple common configurations and / or multiple private configurations. These multiple common configurations and / or multiple private configurations may correspond to multiple transport resources. For example, any one common configuration may correspond to multiple private configurations; for instance, multiple transport resources (such as multiple SS-BWP#B) may correspond to the same common configuration, and these multiple transport resources may correspond to different private configurations. Similarly, two different transport resources (such as multiple SS-BWP#B) may correspond to different common configurations and different private configurations.

[0196] One way the first information can contain multiple common configurations is to include SS-BWP-B-CommonConfig, which can contain multiple common configurations. As an example, SS-BWP-B-CommonConfig can be configured as: {{SCS=15kHz, CP=4.7μs, PointC=6425MHz,…},{SCS=120kHz, CP=4.7μs, PointC=6725MHz,…},…}. Here, {SCS=15kHz, CP=4.7μs, PointC=6425MHz,…} and {SCS=120kHz, CP=4.7μs, PointC=6725MHz,…} represent different common configurations.

[0197] As an example of configuring the first transmission resource, in S101, the first device can send first configuration information and second configuration information. The first configuration information is used to configure a first common configuration of the first transmission resource, and the second configuration information can be used to configure a first dedicated configuration of the first transmission resource. Furthermore, the first common configuration can also be the configuration of other transmission resources; therefore, when configuring other transmission resources, the second information need not be sent again to avoid redundant configuration and reduce configuration overhead.

[0198] It is understandable that in scenarios where the first frequency band contains multiple SS-BWP#Bs, referring to the configuration information of the first transmission resource, the first information may also carry the configuration information of at least one other transmission resource (such as a third transmission resource). For example, the configuration information of the third transmission resource can be used to configure the third transmission resource, and the configuration information of the third transmission resource may include the time-domain information and frequency-domain information of the third transmission resource. In addition, the first information may also include the index and / or parameter set of the third transmission resource. The parameter set can also be replaced with parameters such as subcarrier spacing, cyclic prefix length, or symbol length.

[0199] In one possible embodiment, the first information includes the types and configuration information of multiple transmission resources, wherein the type and configuration information of each transmission resource can be combined to indicate the same information. For example, the first information includes the types and frequency domain information of a first transmission resource and a third transmission resource, and the type and frequency domain information of the first transmission resource are combined into a single information set. The type and frequency domain information of the third transmission resource are combined into a single information set. And so on. Here, i represents the index of the first transmission resource, and j represents the index of the third transmission resource. and These represent the offsets between the first transmission resource and the reference frequency, and the offsets between the third transmission resource and the reference frequency, respectively. and TI represents the bandwidth of the first transmission resource and the bandwidth of the third transmission resource, respectively. i and TI j These represent the types of the first and third transmission resources, respectively. That is, the first information includes:

[0200] Furthermore, in the type and configuration information of multiple transmission resources, parameters of the same type can be indicated together, or in other words, multiple parameters of each transmission resource can be indicated separately. For example, the first transmission resource... and third transmission resources Merge into a single information set First transmission resource and third transmission resources Merge into a single information set TI of the first transmission resource i and TI of third transmission resources j Merged into a single information set {TI i TI j The first piece of information can include: {TI i TI j}

[0201] S102: The first device sends the first information.

[0202] Correspondingly, the second device receives the first information.

[0203] The first device can transmit the first information through the transmission resources of the first communication system and / or the transmission resources of the second communication system. Specifically, transmitting the first information through the transmission resources of both the first and second communication systems allows the second device in both systems to receive the first information. For example, in S102, the first device can transmit the first information through the second transmission resources in the first frequency band. Since the first frequency band is a coexisting band of the first and second communication systems, it allows devices in both systems to receive the first information.

[0204] The second transmission resource can be a time-frequency resource in the first frequency band. For example, the second transmission resource is SS-BWP#A in the first frequency band. The first information can be carried on a shared signal between the first and second communication systems to support the second device in the first and / or second communication systems to receive the first information. This shared signal can be a signal used by both the first and second communication systems, such as an on-off keying (OOK) signal or an orthogonal frequency division multiplexing (OFDM) signal. Alternatively, the first information can also be carried on a signal from the first communication system (such as a signal in a cellular network system). Correspondingly, the second device in the second communication system (such as a STA) can be adapted to receive signals from the first communication system. The signal from the first communication system can be an OOK signal or an OFDM signal, etc. Furthermore, the controller can receive and parse the first information sent by the network device in the first communication system, and then send the parsed first information to the terminal in the second communication system, as shown in system C in Figure 2.

[0205] Similarly, the first information can also be carried on the signal of the second communication system (such as the signal in a WiFi network system). Accordingly, the second device (such as the UE) in the first communication system can be adapted to support receiving signals from the second communication system. The signal of the second communication system can be an OOK signal or an OFDM signal, etc. Furthermore, the controller can receive and parse the first information sent by the network device in the second communication system, and then send the parsed content of the first information to the terminal in the first communication system, as shown in system D in Figure 2.

[0206] It is understood that this application does not limit the second transmission resource to being used to send other shared signals besides the first information.

[0207] In various embodiments of this application, the second transmission resource can be configured using fourth information. This fourth information may include resource information of the second transmission resource. The resource information of the second transmission resource may include frequency domain information and / or time domain information of the second transmission resource.

[0208] The frequency domain information of the second transmission resource may include at least one of the following: the frequency point of the second transmission resource, the reference frequency point information of the second transmission resource, the offset between the second transmission resource and the reference frequency point, or the bandwidth of the second frequency domain resource.

[0209] The frequency point of the second transmission resource, the reference frequency point information of the second transmission resource, the offset between the second transmission resource and the reference frequency point, and the bandwidth of the second frequency domain resource are introduced below.

[0210] (1) The frequency point of the second transmission resource can represent the frequency location of the second transmission resource. For example, the frequency range of the second transmission resource can be represented by ARFCN.

[0211] (2) The reference frequency information of the second transmission resource can be a reference point in the frequency domain.

[0212] Referring to the description of the reference frequency information of the first transmission resource, the reference frequency information of the second transmission resource in this application can be point C, meaning that the second transmission resource can share the reference frequency with the first transmission resource. Alternatively, the reference frequency of the second transmission resource can be point A or another frequency in the existing frequency band of the first communication system.

[0213] The configuration method for the reference frequency information of the second transmission resource can refer to the configuration method for the reference frequency information of the first transmission resource. For example,

[0214] (3) The offset between the second transmission resource and the reference frequency can be used to determine the frequency domain difference between the high-frequency boundary or low-frequency boundary of the second transmission resource and the reference frequency. Therefore, the second device can determine the frequency domain difference based on the offset, and determine the high-frequency boundary or low-frequency boundary of the second transmission resource based on the frequency domain difference and the reference frequency.

[0215] The configuration method for the offset between the second transmission resource and the reference frequency point can refer to the configuration method for the offset between the first transmission resource and the reference frequency point. The offset between the first transmission resource and the reference frequency point can indicate... Among them, the frequency domain difference between the high-frequency boundary or low-frequency boundary of the second transmission resource and the reference frequency point, And the bandwidth settings can satisfy a functional relationship. For example, the offset between the first transmission resource and the reference frequency can be configured as follows: and Numerical values ​​or configurations with functional relationships Indexes in the candidate set of values, etc.

[0216] (4) The bandwidth of the second frequency domain resource represents the size of the bandwidth occupied by the second transmission resource. The configuration method of the bandwidth of the second frequency domain resource can refer to the configuration method of the bandwidth of the first frequency domain resource. Specifically, the bandwidth of the second frequency domain resource can indicate... The bandwidth used to represent the second frequency domain resource usage is The bandwidth can be multiplied by a factor of 1. For example, the bandwidth of the second frequency domain resource can be configured as 1.5 times the set bandwidth. and Numerical values ​​with functional relationships, or configured as Indexes in the candidate set of values, etc.

[0217] In addition, the fourth information may also include the parameter set of the second transmission resource.

[0218] It is understood that the frequency domain location of the second transmission resource can be a known frequency domain location within the first frequency band. For example, the frequency domain location of the second transmission resource can be defined through signaling configuration or pre-configuration. Upon receiving the fourth information, the second device can detect the first information based on the known frequency domain location.

[0219] The time-domain information of the second transmission resource may include the starting time-domain position and / or time-domain length of the second transmission resource.

[0220] The starting time domain location and time domain length are explained below.

[0221] (1) The starting time domain position of the second transmission resource may refer to the starting time of the second transmission resource in the time domain, or it may refer to the time interval between the starting position of the second transmission resource and the time domain resource occupied by the fourth information.

[0222] Referring to the configuration method of the starting time domain position of the first transmission resource, the starting time domain position of the second transmission resource can be configured as follows: and Numerical values ​​that satisfy a functional relationship, or from the set of candidate numerical values. The index. Among them, It can indicate the start time of the second transmission resource in the time domain, or it can indicate the time interval between the start position of the second transmission resource and the time domain resource occupied by the fourth information. The unit can be an absolute duration (such as milliseconds) or the duration of the time domain unit of the first communication system and / or the second communication system.

[0223] (2) The time domain length of the second transmission resource can refer to the amount of time occupied by the second transmission resource.

[0224] Referring to the configuration method of the starting time domain position of the first transmission resource, the starting time domain position of the second transmission resource can be configured as follows: and Numerical values ​​that satisfy a functional relationship, or from the set of candidate numerical values. The index. Among them, It can represent the duration of time occupied by the second transmission resource. The unit can be an absolute duration (such as milliseconds) or the duration of the time domain unit of the first communication system and / or the second communication system.

[0225] It is understood that the time-domain information of the second transmission resource is optional. When the fourth information carries the time-domain information of the second transmission resource, the second device can determine the time-domain location of the second transmission resource based on the time-domain information, and thus start detecting the first information sent by the first device on the second transmission resource based on the time-domain location of the second transmission resource.

[0226] As one implementation of the fourth information, it may omit the time-domain information of the second transmission resource to reduce transmission overhead. As another implementation without the time-domain information of the second transmission resource, the time interval between the start time of the second transmission resource and the transmission resource occupied by the fourth information can be defined through signaling configuration or pre-configuration. As shown in Figure 9, the first device can, for a period of time after sending the fourth information... Then, the first information is sent via the second transmission resource. Alternatively, the second transmission resource can be defined as the interval between the transmission resources occupied by the fourth information. The transmission resources. In this implementation, The corresponding duration can be used by the second device to receive and parse the fourth information in order to obtain the frequency domain information of the second transmission resource, i.e. The time required for the second device to receive and parse the fourth information is equal to or greater than the time required for the second device to receive and parse the fourth information. Accordingly, after parsing the fourth information, the second device can detect the first information based on the frequency domain information of the second transmission resource.

[0227] Furthermore, the frequency domain information of the second transmission resource can also be known. After receiving the fourth information, the second device can begin detecting the first information carried by the second transmission resource at a known frequency domain location. In other words, the fourth information can be understood as switch information, used to indicate whether the second device should start detecting the first information.

[0228] In various embodiments of this application, the fourth information can reuse 5G BWP indication signaling. For example, 5G BWP indication signaling can be used to configure BWP, and in this application, SS-BWP-A-Config can be added to the BWP indication signaling as the fourth information. For example, SS-BWP-A-Config is used to configure the second transmission resource. Alternatively, the fourth information can also be independent of the BWP indication signaling. For example, SS-BWP-A-Config can be carried through RRC messages, MAC CE, or DCI, etc., and SS-BWP-A-Config can serve as the fourth information.

[0229] In one possible embodiment, the fourth information can be carried on the transmission resources of the first communication system. Here, the transmission resources of the first communication system can be located in the traditional frequency band of the first communication system, that is, a frequency band supported by the first communication system but not by the second communication system. For example, the transmission resources of the first communication system are licensed frequency bands of the first communication system. Based on this embodiment, the second device can operate in the traditional frequency band of the first communication system. If the second device detects the fourth information in this frequency band, it can start detecting the first information in the second transmission resources based on the fourth information and transmit it in the first transmission resources according to the first information, thus avoiding the second device detecting the first frequency band for an extended period.

[0230] Similarly, the fourth piece of information can be carried on the transmission resources of the second communication system. For example, the transmission resources of the first communication system are the licensed frequency bands of the second communication system.

[0231] S103: The second device transmits data through the first transmission resource.

[0232] In S103, the second device can send or receive data through the first transmission resource. This first transmission resource allows the second device to transmit data with the first device, or with other network devices or terminals besides the first device; this application does not specifically limit this.

[0233] It is understood that if the first transmission resource belongs to unlicensed spectrum, the second device can access the first transmission resource and perform transmission through a contention mechanism. This application does not specify the contention method; existing contention methods can be referenced.

[0234] Specifically, when the first transmission resource is an active transmission resource, the second device can transmit data through the first transmission resource.

[0235] Optionally, the second device can receive second information, which can be used to indicate that the first transmission resource is an active transmission resource; this second information can also be called an activation indication. Accordingly, the second device can determine that the first transmission resource is an active transmission resource based on the second information. Taking SS-BWP#B as an example, the second information can specifically be used to indicate that the first transmission resource is an active BWP.

[0236] Specifically, the second information may include an index and / or resource information of the first transmission resource. The resource information may include, for example, frequency domain information and / or time domain information, as described in S101. That is, in this application, the activation instruction may carry the index and / or resource information of the activated SS-BWP#B to indicate the activated SS-BWP#B.

[0237] When the second information includes an index of the first transmission resource, the second information can be an SS-BWP activation identifier (SS-BWP-B-activateID) field. The SS-BWP activation identifier field can be used to carry an index of the activated SS-BWP#B. This field can be carried in the BWP indication or in newly added signaling. The newly added signaling, for example, is the SS-BWP-B-set field. For the SS-BWP#B of the communication system, the newly added signaling can be carried in RRC messages, MAC CE, or DCI, without specific restrictions.

[0238] For example, the second device obtains SS-BWP-B-set = {SS-BWP#B Index i, SS-BWP#BIndex j, ..., SS-BWP#B Index k} from the first information or existing frequency band. The second information is the SS-BWP-B-activateID field, which can carry index j to indicate that the activated SS-BWP#B is the SS-BWP#B with index j.

[0239] It is understandable that the index of the active SS-BWP#B can be carried in the same signaling (or message or field) as the indexes of multiple allocated SS-BWP#Bs. As an example of merging the transmission of the first and second information, as described in S101 regarding the first information, the first information can carry the indexes of multiple allocated SS-BWP#Bs, and can further carry the second information, i.e., the index of the active SS-BWP#B, within the first information. For example, the first information carries SS-BWP-B-set={j,SS-BWP#B Index i,SS-BWP#B Index j,…,SS-BWP#B Index k}, where j represents the active SS-BWP#B with index j, and SS-BWP#B Index i, SS-BWP#B Index j,…,SS-BWP#B Index k respectively represent multiple allocated SS-BWP#Bs with indices i, j…k.

[0240] This can also be understood as the first and second pieces of information being merged into a single message. This merged message can contain the index of the active SS-BWP#B and the indexes of multiple allocated SS-BWP#Bs. Alternatively, it can be said that the first and second pieces of information can be sent together. For example, the merged message might carry SS-BWP-B-set = {j, SS-BWP#B Index i, SS-BWP#B Index j, ..., SS-BWP#B Index k}.

[0241] Furthermore, the index of the activated SS-BWP#B can also be sent independently of the indexes of the multiple allocated SS-BWP#Bs; in other words, the first message can be sent independently of the second message.

[0242] In addition, the indexes of the multiple SS-BWP#Bs allocated can also be carried in the traditional frequency band.

[0243] Optionally, the second information may also include indexes and / or resource information of other activated transmission resources, meaning the second information can be used to activate multiple transmission resources, including the first transmission resource. The time-frequency resources of the activated multiple transmission resources do not overlap.

[0244] In one possible embodiment, the second information can be carried on the transmission resources of either the first or second communication system. Specifically, if the first transmission resource is the transmission resource of the first communication system, then the second information can be carried on the transmission resource of the first communication system. This transmission resource of the first communication system can be located in a conventional frequency band (such as a licensed frequency band) or a coexisting frequency band. The coexisting frequency band can be a previously activated SS-BWP#B.

[0245] As shown in Figure 10, the dashed rectangles represent the positions of SS-BWP#Bs in the first communication system, and the solid rectangles represent the positions of SS-BWP#Bs activated at different times. The numbers in the rectangles represent the indices of each SS-BWP#B. As indicated by the arrows, the activated SS-BWP#B shown in number ① can be activated by activation indication #1 carried by the licensed frequency band of the first communication system. That is, if the activated SS-BWP#B shown in number ① is considered the first transmission resource, then the second information can be carried in the licensed frequency band. Furthermore, the activated SS-BWP#B shown in number ② can be activated by activation indication #2 carried by the activated SS-BWP#B shown in number ①. That is, still considering the activated SS-BWP#B shown in number ① as the first transmission resource, the first device can send third information (i.e., activation indication #2) in this first transmission resource. The third information is used to indicate other SS-BWP#Bs. For example, the third information can be used to indicate one or more next activated SS-BWP#Bs (such as the fourth transmission resource). The third information can be implemented with reference to the second information, the difference being that they are used to activate different SS-BWP#Bs. Furthermore, if the activated SS-BWP#B shown in number ① is regarded as the first transmission resource, then the second information (i.e., activation indication #2) can be carried in the coexisting frequency band.

[0246] Similarly, if the first transmission resource is the transmission resource of the second communication system, then the second information can be carried on the transmission resource of the second communication system. This transmission resource of the second communication system can be located in the traditional frequency band (such as a licensed frequency band) of the second communication system, or it can be located in a coexisting frequency band.

[0247] It is understandable that the second information can be sent by a network device belonging to the same network system as the second device. That is, the first information and the second information can be sent by different network devices. Taking the second information carried on the transmission resources of the first communication system as an example, if the first device is a controller, or if the first device is a network device and the network device belongs to a different communication system than the second device, then the first device does not support sending the second information through the transmission resources of the first communication system and needs to send the second information through a network device in the first communication system. For example, this network device could be the base station to which the second device is currently connected.

[0248] Furthermore, in scenarios where the location of the second device changes, the first and second information can be sent by different network devices within the same communication system. For example, the first information may be sent by network device #1 to which the second device is connected. If the second device moves, the SS-BWP#B configured in the first information may still be valid, and network device #2 can send the second information to the second device to activate the first transmission resource.
