[0001] Cross-references to related applications
[0002] This application claims priority to Chinese Patent Application No. 202410954791.5, 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 or access point (AP)), 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 configuration information of a first transmission resource, wherein the first transmission resource is in a first frequency band, which is a communication frequency band supported by both a first communication system and a second communication system, and the first transmission resource is a transmission resource of the first communication system; wherein the first communication system is a cellular communication system and the second communication system is a non-cellular communication system, or the first communication system is a non-cellular communication system and the second communication system is a cellular communication system; the first device can also transmit the configuration information of the first transmission resource through a second frequency band, which is a frequency band supported by the first communication system.
[0008] Based on this implementation, the first device can configure the transmission resources in the first frequency band shared by the first and second communication systems using the configuration information of the first transmission resources. Furthermore, the first device can send the configuration information of the first transmission resources via the second frequency band supported by the first communication system. Correspondingly, when the second device receives the configuration information of the first transmission resources via the second frequency band supported by the first communication system, it can determine that the first transmission resource is a transmission resource of the first communication system. Therefore, it is not necessary to explicitly indicate the type of the first transmission resource, which can reduce transmission overhead.
[0009] As an example, the configuration information of the first transmission resource is included in the first information, and the first device transmits the first information through the second frequency band.
[0010] In one possible implementation, the configuration information of the first transmission resource includes first configuration information and second configuration information. The first configuration information includes a first common configuration of the first transmission resource, and the second configuration information includes a first dedicated configuration of the first transmission resource.
[0011] Based on this implementation, the configuration information of the first transmission resource can be divided into common configuration and dedicated configuration. In this application, common configuration can refer to the static or semi-static configuration of the transmission resource, while dedicated configuration can refer to the dynamic configuration of the transmission resource. It can also be understood that common configuration is a configuration shared by multiple terminals or transmission resources, while dedicated configuration can be a configuration specific to a single terminal or transmission resource. The common configuration and dedicated configuration 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.
[0012] In one possible implementation, the first common configuration includes at least one of the following: subcarrier spacing; cyclic prefix length; parameter set; reference frequency information; the first dedicated configuration includes at least one of the following: information on time-domain resources; information on frequency-domain resources.
[0013] In one possible implementation, the first private configuration includes an index of the first public configuration.
[0014] Based on this implementation, the index of the first common configuration can be used to indicate the first common configuration, thereby improving the efficiency of indicating the common configuration. For example, when configuring the correspondence between the first common configuration and the first private configuration in a subsequent configuration, the first private configuration can contain or correspond to the index of the first common configuration.
[0015] In one possible implementation, the first common configuration corresponds to a first time-domain resource range and / or a first frequency-domain resource range and a second time-domain resource range, and the first dedicated configuration is used to configure the time-domain resources and / or frequency-domain resources of the first transmission resource; wherein, the first time-domain resource range includes the time-domain resources of the first transmission resource, and / or, the first frequency-domain resource range includes the frequency-domain resources of the first transmission resource.
[0016] Based on this implementation, the correspondence between the first common configuration and the first dedicated configuration can be determined according to the time-domain and / or frequency-domain resource range corresponding to the first common configuration, and the time-domain and / or frequency-domain resources of the first transmission resources indicated by the first dedicated configuration. Therefore, even without configuring an index for the common configuration, the configuration of the correspondence between the first common configuration and the first dedicated configuration can be effectively achieved.
[0017] In one possible implementation, the first information also includes the correspondence between the first common configuration and the first time-domain resource range and / or the first frequency-domain range.
[0018] Based on this implementation, the first device can configure or indicate the correspondence between the first common configuration and the first time-domain resource range and / or the first frequency-domain range through the first information. The first information can be carried in a second frequency band supported by the first communication system.
[0019] In one possible implementation, the first information also includes an index of the first public configuration.
[0020] Based on this implementation, the first device can configure or indicate the index of the first common configuration through the first information. The first information can be carried in a second frequency band supported by the first communication system.
[0021] In one possible implementation, the first information further includes configuration information for a second transmission resource, which is the transmission resource of the first communication system.
[0022] 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 second transmission resource, to improve configuration efficiency.
[0023] In one possible implementation, the configuration information of the second transmission resource includes third configuration information and fourth configuration information. The third configuration information includes a second common configuration of the second transmission resource, and the fourth configuration information includes a second private configuration of the second transmission resource.
[0024] Based on this implementation method, the third and fourth configuration information can be referred to the first and second configuration information, respectively. That is, the configuration method of the second transmission resource can be referred to the configuration method of the first transmission resource, which will not be elaborated further.
[0025] In one possible implementation, the first information further includes at least one of the following: the number of public configurations, which include the first public configuration and / or the second public configuration; and the index of the second public configuration.
[0026] Based on this implementation method, multiple common configurations can be configured in the first information, as well as the number of multiple common configurations and the index of each common configuration.
[0027] In one possible implementation, the first device may also send second information, which includes an updated first public configuration and / or an updated first private configuration.
[0028] Based on this implementation, the first device can update the first public configuration and / or the first private configuration through the second information to achieve flexible updates of the transmission resource configuration.
[0029] In one possible implementation, the second information includes an index of the first public configuration.
[0030] Based on this implementation, the index of the first public configuration can be used to indicate the first public configuration and / or the first private configuration to be updated.
[0031] In one possible implementation, the second information also includes an updated second common configuration of the second transmission resource and / or an updated second private configuration of the second transmission resource.
[0032] Based on this implementation, the second information can be used to update multiple configurations of the transmission resources, such as updating at least one common configuration and / or at least one private configuration, to achieve efficient configuration updates.
[0033] In one possible implementation, the second information also includes an index of the second public configuration.
[0034] In one possible implementation, the second information includes an update operation index indicating an update method, which includes at least one of the following: adding a configuration parameter; adding a configuration attribute; deleting a configuration parameter; deleting a configuration attribute; replacing a configuration parameter; replacing a configuration attribute; resetting a configuration parameter.
[0035] Based on this implementation, the type of update method can be flexibly indicated by the update operation index, thereby improving the efficiency of indication.
[0036] In one possible implementation, the second information is carried in the second frequency band or the first frequency band.
[0037] Based on this implementation method, update instructions can be sent through coexisting frequency bands or frequency bands supported by the first communication system to achieve flexible updates of transmission configuration.
[0038] Secondly, embodiments of this application provide a communication method, which can be executed by a second device. Unless otherwise specified, the term "second device" in this application can refer to the second device itself (e.g., a user equipment (UE) or station (STA) terminal or terminal device), a component within the second 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 second device. The method includes: the second device receiving configuration information of a first transmission resource via a second frequency band, wherein the first transmission resource is in the first frequency band, which is a communication frequency band supported by both a first communication system and a second communication system, and the first transmission resource is the transmission resource of the first communication system; wherein the first communication system is a cellular communication system and the second communication system is a non-cellular communication system, or the first communication system is a non-cellular communication system and the second communication system is a cellular communication system; the second device can also transmit data through the first transmission resource.

The first configuration information includes a first common configuration of the first transmission resource, and the second configuration information includes a first dedicated configuration of the first transmission resource.
[0040] In one possible implementation, the first configuration information and the second configuration information are carried on different transmission resources in the second frequency band.

[0042] In one possible implementation, the first private configuration includes an index of the first public configuration.
[0043] In one possible implementation, the first common configuration corresponds to a first time-domain resource range and / or a first frequency-domain resource range and a second time-domain resource range, and the first dedicated configuration is used to configure the time-domain resources and / or frequency-domain resources of the first transmission resource; wherein, the first time-domain resource range includes the time-domain resources of the first transmission resource, and / or, the first frequency-domain resource range includes the frequency-domain resources of the first transmission resource.
[0044] In one possible implementation, the first information further includes the correspondence between the first common configuration and the first time domain resource range and the first frequency domain range, the index of the first common configuration, the configuration information of the second transmission resource, and the number of common configurations. The common configuration includes at least one of the first common configuration and / or the second common configuration, or the index of the second common configuration. The above content can be referred to the description in the first aspect.

[0053] 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).

[0080] The specific implementation of this application will be described below with reference to the accompanying drawings in the embodiments of this application.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment.
[0086] 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.
[0087] A terminal can also be called a terminal device, user equipment (UE), station (STA), mobile station (MS), or mobile terminal (MT). Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. 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.
[0088] 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.
[0089] 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.
[0090] 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. For terminals 120j that access the wireless access network 100 through 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.
[0091] 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 access point. 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 access point.
[0092] 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.
[0093] 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.
[0094] 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.
[0095] 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.
[0096] 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.
[0097] "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.
[0098] 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".
[0099] 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.
[0100] 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.
[0101] 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).
[0102] 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.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] 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.
[0109] 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.
[0110] 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.
[0111] 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.
[0112] 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 can also be referred to as a coexisting frequency band or a shared frequency band. Furthermore, a network device can send configuration information for a first transmission resource via a second frequency band supported by the first communication system. This configuration information is used to configure the first transmission resource within the first frequency band. Specifically, the second frequency band is a frequency band supported by the first communication system but not supported by the second communication system. The type of the first transmission resource is a transmission resource of the first communication system; that is, the first transmission resource is a transmission resource of the first communication system. Correspondingly, when the second device receives the configuration information for the first transmission resource via the second frequency band supported by the first communication system, it can determine that the first transmission resource is a transmission resource of the first communication system.
[0113] It can also be understood that if it is necessary to configure the transmission resources of the second communication system, the first device can send the configuration information of the transmission resources of the second communication system through the frequency band supported by the second communication system (such as the third frequency band).
[0114] Therefore, based on the method provided in the embodiments of this application, the indication of transmission resources of any communication system in a shared spectrum can be efficiently realized.
[0115] In this method, the first communication system can be a cellular network system such as LTE, 5G, or a future communication system, and correspondingly, the second communication system can be a non-cellular network system such as WiFi. Alternatively, the first communication system can be a non-cellular network system such as WiFi, and correspondingly, the second communication system can be a cellular network system such as LTE, 5G, or a future communication system.
[0116] It is also understood that the meanings of the first communication system and the second communication system can change in practical applications, meaning that the embodiments of this application can also be applied to other scenarios. For example, the first communication system and the second communication system can also be two different cellular systems (such as LTE and 5G, respectively), or two different non-cellular systems. In addition, 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 communication system and the second communication system, share spectrum.
[0117] In this application, the first frequency band may include one or more layered BWPs (spectrum-sharing BWPs, SS-BWPs). Any SS-BWP can be a transmission resource of either the first or second communication system. It can be understood that the configuration information of the first transmission resource in this application can be used to configure the SS-BWP, that is, the configuration information of the first transmission resource can be used as the SS-BWP configuration (SS-BWP-Config).
[0118] In one possible embodiment, the time-frequency resources of any two SS-BWPs do not overlap, that is, the time-domain resources occupied by any SS-BWP are different from those occupied by other SS-BWPs, and / or, the frequency-domain resources occupied by any SS-BWP are different from those occupied by other SS-BWPs. As shown in Figure 3, the first frequency band may contain multiple SS-BWPs, and the time-domain and frequency-domain resources of any two SS-BWPs do not overlap.
[0119] The method will be described below with reference to the process shown in Figure 4.
[0120] 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 or an access point (AP), and the second device can be at least one of a user interface (UE) or a standby device (STA).
[0121] S101: The first device determines the configuration information of the first transmission resource. The first transmission resource is located in a first frequency band, which is a communication frequency band shared by the first communication system and the second communication system.
[0122] 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.
[0123] 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.
[0124] 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. The first frequency band can contain one or more SS-BWPs.
[0125] As an example, as shown in Figure 5, 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 (such as the first transmission resource) can be one of these time-frequency resource units, or it can contain multiple time-frequency resource units. Optionally, each time-frequency resource is the minimum 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, i.e., 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, i.e., 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.
[0126] 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.
[0127] It is understandable that if SS-BWP is a transmission resource of a cellular network system, then it can have the frame structure of a cellular network system. Taking SS-BWP as the time-frequency resource unit represented by number (1) in Figure 5 as an example, the frame structure of this SS-BWP can contain multiple radio frames, each radio frame can include multiple subframes, and each subframe can include multiple time slots.
[0128] Similarly, if the SS-BWP is a transmission resource for a non-cellular network system, then the SS-BWP can have the frame structure of a non-cellular network system. Taking the non-cellular network system as a WiFi network system and the SS-BWP as the time-frequency resource unit represented by number (2) in Figure 5 as an example, the frame structure of the SS-BWP can contain multiple physical layer protocol data units (PPDUs). Each PPDU can include a legacy short training field (L-STF), a legacy long training field (L-STF), a legacy signal (L-SIG), a high throughput signal (L-SIG), a repetitive legacy signal (RL-SIG), and data, etc.
[0129] It is understandable that, given the known frequency and time domain ranges of the first frequency band, the time and frequency domain information of each transmission resource unit can be determined. Therefore, the time-frequency resource unit occupied by the first transmission resource can be determined based on this number. In other words, in this example, the configuration information of the first transmission resource does not need to carry the complete time 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. Correspondingly, the second device can determine the time 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.
[0130] As another example, any SS-BWP (such as the first transmission resource) can have flexible frequency domain and / or time domain dimensions. As shown in Figure 6, different SS-BWPs can have different frequency domain and / or time domain dimensions, and the first transmission resource can be one of multiple SS-BWPs. In this example, the configuration information of the first transmission resource can be flexibly configured to include its frequency domain and / or time domain information, enabling 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 may include 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.
[0131] 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.
[0132] 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. Furthermore, dedicated configurations for different transmission resources can be carried on the same or different transmission resources. As shown in Figure 7, configuration information #1, configuration information #2, and configuration information #3 can each be carried on different transmission resources.
[0133] In addition, the first configuration information and the second configuration information can have different transmission periods (or signaling periods), etc.
[0134] 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.
[0135] 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.
[0136] As one implementation approach, configurations that are not frequently updated in different SS-BWPs and / or can be applied to multiple receivers can be used as common configurations to reduce the overhead of duplicate indications.
[0137] 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.
[0138] As an example, the first common configuration may include at least one of the following parameters: a parameter set (numerology), 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.
[0139] 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.
[0140] 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.
[0141] 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 is, for example, the SS-BWP Common Configuration (SS-BWP-CommonConfig) field. As an example of the SS-BWP-CommonConfig field, SS-BWP-CommonConfig can be configured as {SCS = 15kHz, CP = 4.7μs, PointC = 6425MHz,…}, indicating that the subcarrier spacing is 15kHz, the cyclic prefix length is 4.7μs, and the point C frequency domain position is 6425MHz.
[0142] 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.
[0143] Additionally, the first dedicated configuration may include time-domain information and / or frequency-domain information. As shown in Figure 7, the second configuration information can be used to indicate the time-frequency resources of the SS-BWP in the first frequency band.
[0144] Specifically, the first dedicated configuration can be used to determine or indicate the frequency domain information and / or time domain information of the first transmission resource.
[0145] 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.
[0146] 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.
[0147] 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.
[0148] (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.
[0149] (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.
[0150] As an example, the offset between the first transmission resource and the reference frequency can be indicated by Freqloc. The frequency domain difference between the high-frequency or low-frequency boundary of the first transmission resource and the reference frequency, Freqloc, and the set bandwidth can satisfy a functional relationship. The second device can determine the offset between the first transmission resource and the reference frequency based on this functional relationship, Freqloc, and the set bandwidth, and further determine the high-frequency or low-frequency boundary of the first transmission resource. As shown in Figure 8, Freqloc can be used to determine the frequency domain difference between the reference frequency (point C in the figure) and the high-frequency or low-frequency boundary of the first transmission resource (the low-frequency boundary in the figure).
[0151] This functional relationship, for example, is that the frequency domain difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency point is a set bandwidth that is Freqloc times. It is understood that Freqloc times is merely an example of a functional relationship, and other functional relationships may also be satisfied between the frequency domain difference, Freqloc, and the set bandwidth; this is not specifically limited. This functional relationship can be configured via signaling or defined through pre-configuration.
[0152] 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.
[0153] In one possible implementation, the offset between the first transmission resource and the reference frequency can be configured as Freqloc, representing a difference of Freqloc times the set bandwidth between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency. Taking the set bandwidth as the bandwidth of a frequency unit as an example, when the first communication system is a cellular network system and the frequency unit is a PRB, Freqloc can represent the number of PRBs. In this case, the offset between the first transmission resource and the reference frequency can be configured as Freqloc, indicating that the difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency is Freqloc times the bandwidth of the PRB, that is, the frequency domain difference between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency is Freqloc times the bandwidth of the PRB.
[0154] In another possible implementation, the offset between the first transmission resource and the reference frequency can also be configured as a value that has a functional relationship with Freqloc. For example, the offset between the first transmission resource and the reference frequency can be configured as N, where N satisfies Freqloc = 2. N Equal functional relationship. With Freqloc = 2 N 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.
[0155] In another possible implementation, the offset between the first transmission resource and the reference frequency can also be configured as the index of Freqloc in the set of candidate values. Taking the bandwidth as the bandwidth of a frequency unit as an example, the set of candidate values is {2, 4, 8, 32, 128}. If Freqloc is 32, then when the index range of the candidate values is 1, 2, 3…, the offset between the first transmission resource and the reference frequency can be configured as 4, where 32 is the fourth value in the set. This configuration of the offset between the first transmission resource and the reference frequency can represent a difference of 32 frequency units between the high-frequency boundary or low-frequency boundary of the first transmission resource and the reference frequency. Furthermore, the indices of the candidate values are 0, 1, 2… etc., without specific limitations. The bandwidth of the frequency unit can use a default setting or can be related to the communication system.
[0156] It is understandable that the set of alternative values can be pre-configured via signaling or based on pre-configuration definitions.
[0157] 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 Freqloc and the information of the frequency unit. The information of the frequency unit can indicate the type or bandwidth of the frequency unit. For example, if the information of the frequency unit is PRBs, it indicates that the frequency unit is a PRB.
[0158] For example, the offset between the first transmission resource and the reference frequency can be configured as Freqloc = 100 PRBs, indicating 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 Freqloc = 120 FDUs, indicating that the high-frequency boundary or low-frequency boundary of the first transmission resource differs from the reference frequency by 100 FDUs.
[0159] Similarly, the offset between the first transmission resource and the reference frequency point can also be configured as the index of Freqloc in the candidate value set and the information of the frequency unit, which will not be elaborated further.
[0160] 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 Freqloc of the first transmission resource. The frequency location information can indicate the frequency of the high-frequency boundary or the low-frequency boundary. Alternatively, it can be understood that the frequency location information of the first transmission resource is determined based on the reference frequency point Freqloc and the aforementioned offset.
[0161] (3) The bandwidth of the first frequency domain resource represents the size of the bandwidth occupied by the first transmission resource.
[0162] As an example, the bandwidth of the first frequency domain resource can indicate the bandwidth size FreqSize, where the bandwidth of the first frequency domain resource, FreqSize, and the set bandwidth can satisfy a functional relationship. As shown in Figure 8, FreqSize can be used to determine the size of the bandwidth occupied by the first transmission resource.
[0163] For example, the bandwidth of the first frequency domain resource is a set bandwidth that is multiples of FreqSize. It is understood that FreqSize is merely an example of a functional relationship, and other functional relationships may also exist between the bandwidth of the first frequency domain resource, FreqSize, and the set bandwidth; this is not specifically limited. This functional relationship can be configured via signaling or defined through pre-configuration.
[0164] 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.
[0165] 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.
[0166] The indication method for FreqSize in the bandwidth of the first frequency domain resource can be found in the description of the Freqloc indication method. For example, the bandwidth of the first frequency domain resource can be configured as FreqSize. Alternatively, the bandwidth of the first frequency domain resource can be configured as a value N' that satisfies a functional relationship with the indication of FreqSize; for example, FreqSize and N' satisfy FreqSize = 2. 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 of FreqSize in the candidate value set; see the implementation of Freqloc indicating Freqloc via the index of Freqloc in the candidate value set. Additionally, the bandwidth of the first frequency resource also includes information about the frequency unit.
[0167] Taking the bandwidth setting as frequency bandwidth as an example, the bandwidth configuration of the first frequency domain resource is FreqSize = 10PRBs, which means that the bandwidth occupied by the first transmission resource is 10 PRBs; the bandwidth configuration of the first frequency domain resource is FreqSize = 20FDUs, which means that the bandwidth occupied by the first transmission resource is 20 FDUs.
[0168] 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.
[0169] The starting time domain location and time domain length are explained below.
[0170] (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.
[0171] For example, the starting time-domain position of the first transmission resource can be configured as Timeloc. As shown in Figure 8, Timeloc 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 of Timeloc 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 a cellular network system, configuring the starting time-domain position of the first transmission resource as Timeloc = 50 slots indicates that the first transmission resource starts at time slot numbered 50, or that the starting position of the first transmission resource is 50 time slots after the transmission resource occupied by the first information.
[0172] For example, the starting time-domain position of the first transmission resource can be configured as a value N” that satisfies a functional relationship with Timeloc, for example, Timeloc = 2. N‘’ 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.
[0173] For example, the starting time-domain position of the first transmission resource can be configured as the index of Timeloc in the candidate value set. See the implementation of indicating Freqloc using the index of Freqloc in the candidate value set. The candidate value set may include Timeloc. This candidate value set can be pre-configured via signaling or based on a pre-defined configuration.
[0174] (2) The time domain length of the first transmission resource can refer to the amount of time occupied by the first transmission resource.
[0175] For example, the starting time domain position of the first transmission resource can be configured as TimeSize. As shown in Figure 8, TimeSize can be used to determine the duration occupied by the first transmission resource. The unit of TimeSize 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 a cellular network system, TimeSize = 32 slots, indicating that the first transmission resource occupies 32 time slots.
[0176] For example, the starting time domain position of the first transmission resource can be configured as a value N”' that satisfies a functional relationship with TimeSize, for example, TimeSize = 2 N‘’‘ Correspondingly, the first transmission resource occupies 2 N”’ Each time slot.
[0177] For example, the starting time-domain position of the first transmission resource can be configured as the index of TimeSize in the candidate value set. See the implementation of Freqloc indicating Freqloc through the index in the candidate value set. The candidate value set may include TimeSize. This candidate value set can be pre-configured via signaling or based on a pre-defined configuration.
[0178] Additionally, the first dedicated configuration may also include other resource information besides resource information that can be used to determine the first transmission resource. For example, the first dedicated configuration 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 first dedicated configuration may include the index of the time-frequency resource unit occupied by the first transmission resource. For example, all time-frequency resource units within the first frequency band can be numbered, and the first dedicated configuration may include the number of the occupied time-frequency resource units. Numbering rules may include, for example, assigning time-frequency resource unit numbers sequentially from 0 (or 1) in descending order of frequency for multiple time-frequency resource units at the same time domain location, or assigning time-frequency resource unit numbers sequentially from 0 (or 1) in ascending order of frequency.
[0179] In this application, the first dedicated configuration can be carried in the 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-DedicatedConfig field. As an example of the SS-BWP-DedicatedConfig field, SS-BWP-DedicatedConfig can be configured as {FreqSize1, Freqloc1, ...}.
[0180] 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-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.
[0181] Optionally, in S101 and S102, the configuration information of the first transmission resource can be carried in the first information. The first information may further include the type of the transmission resource (or type indication (TI)) to indicate that the first transmission resource is a transmission resource of the first communication system. The first information can be carried in the second frequency band. Based on the configuration of the first information, the first communication system can use the first transmission resource in the first frequency band. Therefore, the transmission resources used by the first communication system can be indicated (or allocated or configured) in the coexisting frequency band to improve transmission performance in a shared spectrum scenario.
[0182] 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.
[0183] Optionally, the first information may also include the type of the first transmission resource, used to indicate that the first transmission resource is a transmission resource of a first communication system. For example, the type of the first transmission resource may 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 may be used to indicate that the first transmission resource is a transmission resource of a WiFi network system.
[0184] 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 cellular network 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 first transmission resource is a transmission resource of a non-cellular network system. In addition, the first value can also be 1, and the second value can also be 0.
[0185] In another example, the type of the first transmission resource may also include an identifier (or index or field) corresponding to the first 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. 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.
[0186] Therefore, identifier #1 can be used to represent a cellular network system, and identifier #2 can be used to represent a non-cellular network 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 first transmission resource is a transmission resource of a cellular network 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 first transmission resource is a transmission resource of a non-cellular network system.
[0187] In one possible implementation, in a scenario where multiple SS-BWPs exist in the first frequency band, these multiple SS-BWPs may include an SS-BWP serving 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 (e.g., referred to as a second transmission resource), to indicate that any one of the multiple transmission resources is a transmission resource of the first communication system or a transmission resource of the second communication system. Alternatively, if the first information includes configuration information for multiple transmission resources (e.g., including the first transmission resource and / or the second transmission resource), it can be assumed that all transmission resources belong to the first communication system. In this case, the first information may not carry the type of the transmission resource, or may only carry a 1-bit type indication, thereby reducing transmission overhead.
[0188] For example, the first information may include type indicators for some or all of the multiple SS-BWPs, which can indicate that the corresponding SS-BWP is a transmission resource of the first communication system. Some or all of the multiple SS-BWPs may include a first transmission resource and / or a second transmission resource. For instance, the first information may include a 1-bit type indicator; when the 1-bit type indicator is set to a first value, it indicates that all SS-BWPs are transmission resources of the first communication system. Alternatively, the first information may not carry a type indicator, in which case all SS-BWPs can be assumed to be transmission resources of the first communication system.
[0189] 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-BWPs) may correspond to the same common configuration, and the multiple transport resources may correspond to different private configurations. Similarly, two different transport resources (such as multiple SS-BWPs) may correspond to different common configurations and different private configurations.
[0190] One way the first information can contain multiple common configurations is to include SS-BWP-CommonConfig, which can contain multiple common configurations. As an example, SS-BWP-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.
[0191] As an example, when the first information includes multiple common configurations, the first information may include at least one of the following: the number of common configurations, parameters (such as parameter sets) of the multiple common configurations, the index of the multiple common configurations, or the reference time-frequency position of the common configurations.
[0192] The following sections will introduce the number of common configurations, the parameters of multiple common configurations, the indexes of multiple common configurations, and the reference time-frequency positions of common configurations.
[0193] (1) The number of common configurations can be used to indicate that the first information contains N common configurations, where N is a positive integer greater than 1. For example, the first information can contain the number N of common configurations, or it can contain the index of N in the set of candidate values. For example, if the set of candidate values is {2,4,8,16}, and N=8, then when the index range of the candidate values is 1, 2, 3..., the number of common configurations is configured as 3, where 8 is the 3rd value in the above set, that is, the index of N=8 is 3. In addition, the indices of the candidate values can also be 0, 1, 2... etc., without specific limitation.
[0194] (2) The parameters of multiple common configurations may include the contents of each common configuration. For example, each common configuration includes information such as parameter set, subcarrier spacing, cyclic prefix length or symbol length.
[0195] (3) The index of the common configuration can also be called the common index. In the first information, the indexes of multiple common configurations can include the index (or identifier) of each common configuration, which is used to indicate the index corresponding to each common configuration. In this application, since the first common configuration and the first dedicated configuration can be carried on different transmission resources, the first information can include the index of each common configuration. Correspondingly, the first dedicated configuration can correspond to the index of the first common configuration. Therefore, the second device can determine the association between the first dedicated configuration and the first common configuration based on the index in the first dedicated configuration, that is, determine that the first common configuration and the first dedicated configuration are the configuration information of the first transmission resource.
[0196] It is understandable that if the first information contains multiple dedicated configurations, then each dedicated configuration can contain an index of the common configuration corresponding to that dedicated configuration. Furthermore, the first information can also contain multiple indexes of dedicated configurations, such as dedicated indexes, used to distinguish and identify different dedicated configurations. The allocation and indication method of the dedicated configuration indexes can refer to the indexes of the common configurations; repetitions will not be repeated. For example, each dedicated configuration can be sorted sequentially from 0 (or 1) in ascending order according to the frequency domain resources indicated by the frequency domain information, from high to low (or low to high).
[0197] The first piece of information may include a common configuration set (CommonConfigSet), which indicates multiple different alternative common configurations. For example, the common configuration set contains multiple alternative common configurations {CommonConfig x}. For instance, the CommonConfigSet might be {{CommonConfig1}, {CommonConfig2}, {CommonConfig3}, {CommonConfig4}, {CommonConfig5}, ...}. The first piece of information may also include a dedicated configuration set (DedicatedConfigSet), which contains one or more dedicated configurations and their corresponding indices. For example, the DedicatedConfigSet might contain multiple dedicated configurations {DedicatedConfig y}. For instance, the DedicatedConfigSet might be {{DedicatedConfig1}, {DedicatedConfig2}, {DedicatedConfig3}, ...}. Each dedicated configuration in the DedicatedConfigSet corresponds to an index of an alternative common configuration. For example, a dedicated configuration might contain the index of a corresponding common configuration; for instance, {DedicatedConfig1} might contain the index of a corresponding common configuration. For example, the index of any dedicated configuration in the dedicated configuration set and its corresponding public configuration are carried together in the DedicatedConfigSet, and their positions in the DedicatedConfigSet are contiguous to indicate the correspondence between them. For instance, the dedicated configuration set is {1, {DedicatedConfig1}, 3, {DedicatedConfig2}…}, where the index of the public configuration corresponding to {DedicatedConfig1} is 1, and the index of the public configuration corresponding to {DedicatedConfig2} is 3.
[0198] As an example of SS-BWP-DedicatedConfig, if SS-BWP-DedicatedConfig contains a dedicated configuration, SS-BWP-DedicatedConfig can be configured as {CommonIndex=Common3,FreqSize1,Freqloc1,…}, which means that the dedicated configurations of FreqSize1 and Freqloc1, etc., correspond to the common configuration with index 3.
[0199] As another example of SS-BWP-DedicatedConfig, if SS-BWP-DedicatedConfig contains multiple dedicated configurations, SS-BWP-DedicatedConfig can be configured as {{CommonIndex=Common3,FreqSize1,Freqloc1,…},{CommonIndex=Common1,FreqSize2,Freqloc2,…},…}, which is used to indicate that dedicated configurations such as FreqSize1 and Freqloc1 correspond to common configurations with index 3, and to indicate that dedicated configurations such as FreqSize2 and Freqloc2 correspond to common configurations with index 1.
[0200] The following section describes how the indexes for each common configuration are determined.
[0201] As an example, the indices of multiple alternative common configurations can be determined according to the order in which they appear in the common configuration set. For instance, in {CommonConfig x}, such as {{CommonConfig1}, {CommonConfig2}, {CommonConfig3}, {Common Config4}, {CommonConfig5}, ..., the index of the common configuration {CommonConfig1} is 1, the index of the common configuration {CommonConfig2} is 2, and so on.
[0202] As another example, the CommonConfigSet or the first information can explicitly show the correspondence between common configurations and their indexes.
[0203] For example, common configurations and their indices are carried in a CommonConfigSet, and their positions in the CommonConfigSet are contiguous to indicate the correspondence between them. For instance, a CommonConfigSet configured as {1,{CommonConfig1},2,{CommonConfig3},3,{CommonConfig5},…} means that the index of CommonConfig1 is 1, the index of CommonConfig3 is 2, the index of CommonConfig5 is 3, and so on.
[0204] For example, the CommonConfigSet or the first information can carry an index set, which is used to indicate the index of each common configuration in the CommonConfigSet.
[0205] For example, the value p of the i-th index in the index set indicates that the index i of the p-th common configuration in CommonConfigSet is 1. For instance, CommonConfigSet is {{CommonConfig1},{CommonConfig2},{CommonConfig3},{CommonConfig4},{CommonConfig5}...}, and the index set is {3,2,5...}. Here, the first index "3" corresponds to {CommonConfig3}, the second index "2" corresponds to {CommonConfig2}, and the third index "5" corresponds to {CommonConfig5}. That is, the index of {CommonConfig3} is 1, the index of {CommonConfig2} is 2, and the index of {CommonConfig5} is 3. Correspondingly, the index of the alternative common configuration corresponding to {DedicatedConfig1} is 1, which means that {DedicatedConfig1} corresponds to the first index in the set of alternative common configuration indices. In other words, it means that {DedicatedConfig1} corresponds to the alternative common configuration corresponding to the first index in the set of alternative common configuration indices. That is, {DedicatedConfig1} corresponds to {CommonConfig3}. In other words, {CommonConfig3} and {DedicatedConfig1} are configuration information of a transmission resource (such as the first transmission resource).
[0206] (4) The reference time-frequency location information of the common configuration can indicate the time-frequency resource range corresponding to the common configuration. For example, the reference time-frequency location information of the common configuration can include the time-frequency resource range information corresponding to the common configuration, or in other words, the reference time-frequency location information of the common configuration includes the correspondence between the common configuration and the time-frequency resource range, which may include, for example, a time-domain resource range and / or a frequency-domain resource range. The frequency-domain resource range can be indicated by the frequency-domain information of the time-frequency resource range, and / or the time-domain resource range can be indicated by the time-domain information of the time-frequency resource range. The time-frequency information of the time-frequency resource range can be referred to in the description of the time-domain information of the first transmission resource in this application, and the frequency-domain information of the time-frequency resource range can be referred to in the description of the frequency-domain information of the first transmission resource in this application, and will not be repeated here.
[0207] As an example, the time-frequency information of the time-frequency resource range may include the time-domain start position information CTimeloc and the time-domain length CTimesize of the time-frequency resource range. CTimeloc can refer to the description of the time-domain start position information Timeloc of the first transmission resource, and CTimesize can refer to the description of the time length TimeSize of the first transmission resource. The frequency-domain information of the time-frequency resource range may include the frequency-domain position information CFreqloc and the bandwidth CFreqsize of the time-frequency resource range. CFreqloc can refer to the description of the frequency position information Freqloc of the first transmission resource, and CFreqsize can refer to the description of the bandwidth FreqSize of the first transmission resource.
[0208] In addition, the time and frequency resource range corresponding to the common configuration can also be a set resource range. For example, multiple time and frequency resource ranges can be set through signaling configuration or pre-configuration. Each time and frequency resource range corresponds to a different index or identifier. Then, the time and frequency resource range information corresponding to the common configuration can be the index or identifier of the time and frequency resource range.
[0209] In one possible embodiment, multiple transmission resources (SS-BWPs) may exist within the time-frequency resource range corresponding to a certain common configuration. These multiple transmission resources can each correspond to different dedicated configurations. As shown in Figure 7, configuration information #1 is used to configure common configuration #1, configuration information #2 is used to configure dedicated configurations #1 and #2, and configuration information #3 is used to configure dedicated configuration #3. Dedicated configurations #1 and #3 can correspond to common configuration #1, meaning common configuration #1 is configured as different transmission resources with dedicated configurations #1 and #3, respectively. For example, if the index of common configuration #1 is CommonIndex = 1, dedicated configurations #1 and #3 can carry CommonIndex = 1 to indicate that dedicated configurations #1 and #3 correspond to common configuration #1. Furthermore, dedicated configuration #2 can correspond to other common configurations besides common configuration #1. For example, dedicated configuration #2 can carry CommonIndex = 0 to indicate that dedicated configuration #2 corresponds to the common configuration with index CommonIndex = 0.
[0210] In this application, since the first common configuration and the first dedicated configuration can be carried on different transmission resources, the first information may include the time-frequency resource ranges corresponding to each common configuration. Among them, the second device can determine the association between the common configuration and the dedicated configuration according to the time-frequency resource range corresponding to the first common configuration and the time-frequency resource range of the first transmission resource indicated by the first dedicated configuration. For example, the time-frequency resource range corresponding to the first common configuration includes the first time-domain resource range and / or the first frequency-domain resource range. Among them, the second device can determine the time-frequency resource position of the first transmission resource according to the first dedicated configuration. If it is determined that the first time-domain resource range includes the time-domain resource of the first transmission resource, and / or, the first frequency-domain resource range includes the frequency-domain resource of the first transmission resource, it can be determined that the first common resource corresponds to the first dedicated resource. That is to say, the first time-domain resource range includes the time-domain resource of the first transmission resource indicated by the first dedicated configuration, that is, the frequency-domain position of the first transmission resource is within the first frequency-domain resource range. For example, the frequency-position information CFreqloc1 and the bandwidth CFreqsize1 of the low-frequency boundary of the first time-domain resource range and the frequency-position information Freqloc and the bandwidth FreqSize of the low-frequency boundary of the first transmission resource satisfy: 0 < Freqloc - CFreqloc1 < CFreqsize1 - FreqSize. In addition, the first frequency-domain resource range includes the frequency-domain resource of the first transmission resource indicated by the first dedicated configuration, that is, the time-domain position of the first transmission resource is within the first time-domain resource range.
[0211] As shown in FIG. 9, the first information may include common configuration A, common configuration B, dedicated configuration A, and dedicated configuration B. Among them, dedicated configuration A includes the resource information of transmission resource #1, and dedicated configuration B includes the resource information of transmission resource #2. If the time-frequency resource range corresponding to common configuration A is time-frequency resource range #1, and the time-frequency resource range corresponding to common configuration B is frequency resource range #2. Among them, if the second device determines that the time-frequency resource of transmission resource #1 is within time-frequency resource range #1 according to dedicated configuration A, it can be determined that common configuration A is the common configuration of transmission resource #1. In addition, if the second device determines that the time-frequency resource of transmission resource #2 is within time-frequency resource range #2 according to dedicated configuration B, it can be determined that common configuration B is the common configuration of transmission resource #2.
[0212] In the example of FIG. 9, common configuration A and common configuration B can be sent through the same message (information or signaling or field or resource).
[0213] In one possible embodiment, when the first information includes multiple common configurations and / or multiple dedicated configurations, the different common configurations and / or dedicated configurations may have different signaling periods (or transmission periods) and may be received by different devices. The signaling periods or receiving devices of the common configurations and / or dedicated configurations may be pre-configured or configured by upper-layer signaling, and this application does not specifically limit this.
[0214] As an example, when there is a one-to-one correspondence between the common configuration and the time-domain resource range, the first information may include the correspondence between the common configuration and the configuration information of the time-domain resource range and / or the configuration information of the frequency-domain resource range.
[0215] For example, the frequency domain location information of the first time-domain resource range is CFreqloc1, and the bandwidth is CFreqsize1. The first information may contain an information set {{SCS1,CP1,…},CFreqloc1,CFreqsize1} consisting of at least the information of the first common configuration and the first time-frequency resource range, where {SCS1,CP1,…} represents the first common configuration. Furthermore, if the first information also includes a second time-frequency resource range and a corresponding second common configuration, where the frequency domain location information of the second time-frequency resource range is CFreqloc2 and the bandwidth is CFreqsize2, the first information may also include an information set {{SCS2,CP2,…},CFreqloc2,CFreqsize2} composed of at least the information of the second common configuration and the first time-frequency resource range, where {SCS2,CP2,…} represents the second common configuration; or, in this case, the first information may include an information set {{{SCS1,CP1,…},CFreqloc1,CFreqsize1},{{SCS2,CP2,…},CFreqloc2,CFreqsize2}}.
[0216] It is understood that in this application, the common configuration can correspond to multiple time-frequency resource ranges, or in other words, the transmission resources of multiple time-frequency resource ranges (or time-frequency resource locations) can share the common configuration. For example, if the first common configuration corresponds to a first time-domain resource range and a second time-frequency resource range, then the first information can include an information set {{SCS1,CP1},CFreqloc1,CFreqsize1,CFreqloc2,CFreqsize2,…} consisting of at least the first common configuration, the first time-domain resource range information, and the second time-frequency resource range information. Furthermore, the first information may also include the correspondence between other common configurations and time-frequency resource range information, which will not be elaborated further.
[0217] In one possible embodiment, the configuration information or first information of the first transmission resource may also include an index of the first transmission resource.
[0218] The index of the first transmission resource can be used to identify the first transmission resource. For example, in a scenario where multiple SS-BWPs exist in the first frequency band, each SS-BWP can correspond to its own index, i.e., multiple SS-BWP indices can be assigned. In this application, the index corresponding to any SS-BWP can be called the index of the assigned SS-BWP. It is understood that the index of the transmission resource can be related to the index of the common configuration and / or the index of the dedicated configuration of the transmission resource. For example, the index of the transmission resource can be a combination of the index of the common configuration and the index of the dedicated configuration, or it can be the index of the dedicated configuration, or it can be a new index assigned based on the index of the common configuration and the index of the dedicated configuration. This application does not specifically limit this. In addition, the index of the transmission resource can also be assigned independently of the index of the common configuration and the index of the dedicated configuration. For an SS-BWP with an assigned index, the active SS-BWP can be indicated by the index of the SS-BWP. For example, when activating an SS-BWP, the active SS-BWP can be indicated by the index.
[0219] As an example, the index allocation rules may include, for example, allocating the indexes of multiple SS-BWPs at the same time domain location sequentially from 0 (or 1) in order of frequency from high to low, or allocating the indexes of SS-BWPs sequentially from 0 (or 1) in order of frequency from low to high.
[0220] Alternatively, indexes can be assigned independently only to the SS-BWPs in the unified communication system. For example, for multiple SS-BWPs in the first communication system, indexes can be assigned sequentially starting from 0 (or 1), and the same applies to the multiple SS-BWPs in the first communication system.
[0221] 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.
[0222] 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-BWPs. In addition, the first device or other network devices may also transmit the index of the SS-BWP 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 of the second communication system through the traditional frequency band of the second communication system.
[0223] 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. Alternatively, the index of the allocated SS-BWP can also be carried through new signaling (or messages or fields). New signaling includes, for example, SS-BWP index (SS-BWP-Index) or SS-BWP set (SS-BWP-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-Index field carrying the index of the allocated SS-BWP as an example, the SS-BWP index field can carry the index of each SS-BWP, for example, SS-BWP-Index = {SS-BWP Index i, SS-BWP Index j, ..., SS-BWP Index k}. Here, i, j, ..., k are the indices of each SS-BWP, and each index corresponds sequentially to the multiple SS-BWPs configured in the first information. Optionally, the SS-BWP index field can also correspond to a time-domain resource. For example, the field carries time-domain information to indicate that the configured index is the index of multiple SS-BWPs occupying that time-frequency resource.
[0224] For example, the first device or other network devices can also send the index of SS-BWPs in other time domains after the active SS-BWP in the coexisting frequency band. For instance, an SS-BWP index field can be sent through an SS-BWP active at a certain time domain location to indicate the indexes of multiple SS-BWPs at the next time domain location. This SS-BWP 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.
[0225] It is understandable that in scenarios where the first frequency band contains multiple SS-BWPs, the first information may also carry configuration information of at least one other transmission resource (such as a second transmission resource), referring to the configuration information of the first transmission resource. For example, the configuration information of the second transmission resource can be used to configure the second transmission resource, and the configuration information of the second transmission resource may include the time-domain information and frequency-domain information of the second transmission resource. In addition, the first information may also include an index of the second transmission resource.
[0226] It is understood that, referring to the description of the configuration information of the first transmission resource, the configuration information of the second transmission resource may include third and fourth configuration information. The third configuration information includes the common configuration of the second transmission resource (such as the second common configuration), and the fourth configuration information includes the dedicated configuration of the second transmission resource (such as the second dedicated configuration). The second common configuration can be referred to in the description of the first common configuration, the only difference being that the first and second common configurations correspond to different transmission resources; repetitions will not be repeated. Similarly, the second dedicated configuration can be referred to in the description of the first dedicated configuration, the only difference being that the first and second dedicated configurations correspond to different transmission resources; repetitions will not be repeated.
[0227] 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 second transmission resource, etc., and the type and frequency domain information of the first transmission resource are combined into an information set {Freqloc}. i FreqSize i TI i The type and frequency domain information of the second transmission resource are merged into an information set {Freqloc}. j FreqSize j TI j}, and so on. Where i represents the index of the first transport resource, j represents the index of the second transport resource, Freqloc i and Freqloc j FreqSize represents the offset between the first transmission resource and the reference frequency, and the offset between the second transmission resource and the reference frequency, respectively. i and FreqSize j TI represents the bandwidth of the first transmission resource and the bandwidth of the second transmission resource, respectively. i and TI j These represent the types of the first and second transmission resources, respectively. That is, the first information includes: {Freqloc} i FreqSize i TI i},{Freqloc j FreqSize j TI j}
[0228] Furthermore, in the type and configuration information of multiple transport resources, parameters of the same type can be indicated together, or in other words, multiple parameters of each transport resource can be indicated separately. For example, the Freqloc of the first transport resource... iFreqloc of the second transport resource j Merge into a single information set {Freqloc} i Freqloc j}, the FreqSize of the first transmission resource i FreqSize of the second transmission resource j Merge into a single information set {FreqSize} i FreqSize j}, TI of the first transmission resource i TI of the second transmission resource j Merged into a single information set {TI i TI j That is, the first piece of information can include: {Freqloc} i Freqloc j},{FreqSize i FreqSize j},{TI i TI j}
[0229] S102: The first device sends configuration information of the first transmission resource through the second frequency band.
[0230] Correspondingly, the second device receives the configuration information of the first transmission resource.
[0231] The second device can be a terminal in the first communication system. For example, if the first communication system is a cellular network system, the second device can be a UE (User Equipment). Or, if the first communication system is a WiFi network system, the second device can be a STA (Stationary Terminal), etc.
[0232] In this application, the second frequency band is a frequency band supported by the first communication system. That is, the first device can transmit configuration information of the first transmission resources through the frequency band or transmission resources of the first communication system. For example, the second frequency band is a licensed frequency band of the first communication system. Alternatively, the configuration information of the first transmission resources can be carried within signals of the first communication system. These signals may be, for example, on-off keying (OOK) signals or orthogonal frequency division multiplexing (OFDM) signals.
[0233] As an example, the second device can support the detection of signals in a second frequency band. When the second device detects the first information carried in the second frequency band, it can obtain the configuration of the first transmission resource based on the configuration information of the first transmission resource.
[0234] The aforementioned second frequency band can be configured via signaling or determined through pre-configuration.
[0235] Understandably, the second frequency band can also be used to transmit signals other than the first information.
[0236] It can also be understood that the second frequency band can be a frequency band supported by a second communication system, or in other words, the configuration information of the first transmission resource can be carried on the signal of the second communication system. This signal of the second communication system can be a signal used by both the first and second communication systems, such as an OOK signal or an OFDM signal. For example, the second frequency band can be a licensed frequency band of the second communication system. For instance, the first device can transmit the first information in a frequency band supported by the second communication system. For example, the first device can be a network device in the second communication system, such as an access point (AP), in which case the first device can transmit the configuration information of the first transmission resource through the second communication system. Correspondingly, the second device can be a terminal in the first communication system, such as a user interface (UE), in which case the second device can be configured to support signal reception in a frequency band supported by the second communication system.
[0237] Taking the first communication system as a WiFi network system and the second communication system as a cellular network system as an example, referring to system C shown in Figure 2, the controller can receive and parse the first information sent by the base station (which is the first device in S101 and S102), and the controller can send the content of the parsed first information to the STA.
[0238] Taking a cellular network system as the first communication system and a WiFi network system as the second communication system as an example, referring to system D shown in Figure 2, the controller can receive and parse the first information sent by the access point (which is the first device in S101 and S102), and the controller can send the content of the parsed first information to the UE.
[0239] It can also be understood that the second frequency band can be a frequency band supported by both the first and second communication systems. Correspondingly, the second device can be a terminal within the first and / or second communication systems. The second frequency band can be a shared frequency band between the first and second communication systems. For example, the first information can be carried on a coexisting signal of the first and second communication systems to support the second device in the first and / or second communication systems in receiving the first information. This coexisting signal can be a signal used by both the first and second communication systems, such as an OOK signal or an OFDM signal.
[0240] S103: The second device transmits data through the first transmission resource.
[0241] 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.
[0242] 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.
[0243] Specifically, when the first transmission resource is an active transmission resource, the second device can transmit data through the first transmission resource.
[0244] In one possible embodiment, the first device may send second information that can be used to update the first configuration information and / or the second configuration information, or in other words, the second information can be used to update the first public configuration and / or the first private configuration. The second information may also be referred to as an update instruction.
[0245] In order to indicate the configuration that needs to be updated, the second information may include an index of the first common configuration and / or an index of the first private configuration. For example, if the configuration to be updated is a common configuration, the second information may include an index of that common configuration. Alternatively, if the configuration to be updated is a private configuration, the second information may include an index of that private configuration, or it may include an index of the common configuration corresponding to that private configuration.
[0246] Additionally, if the network device has not been assigned an index for a public or private configuration, the second information may carry or indicate the time-domain and / or frequency-domain information corresponding to the configuration to be updated.
[0247] Additionally, the second information may include updated first configuration information and / or updated second configuration information. Alternatively, the second information may include updated first public configuration and / or updated first private configuration.
[0248] Specifically, updating the first common configuration with second information can mean that the second information includes an updated first common configuration, such as an updated parameter set, subcarrier spacing, cyclic prefix length, symbol length, or reference frequency information of the first transmission resource. It is understood that after updating the first common configuration, at least one of the parameter set, subcarrier spacing, cyclic prefix length, symbol length, or reference frequency information of the first transmission resource differs from the first transmission resource before the update. Updating the first dedicated configuration with second information can mean that the second information includes an updated first dedicated configuration, such as updated time-domain information and / or frequency-domain information of the first transmission resource. Taking Figure 8 as an example, the update indication of the first transmission resource can be used as second information to update the time-domain and frequency-domain information of the first transmission resource. It is understood that after updating the first dedicated configuration, at least one of Freqloc, FreqSize, Timeloc, or TimeSize of the first transmission resource differs from the first transmission resource before the update.
[0249] In one possible implementation, the second information includes an update operation index to indicate the configuration update method. For example, as shown in Table 1, the configuration update methods include at least one of the following: adding configuration parameters, adding configuration attributes, deleting configuration parameters, deleting configuration attributes, replacing configuration parameters, replacing configuration attributes, or resetting configuration parameters. Here, configuration parameters refer to one or more common configurations and / or one or more dedicated configurations. Attributes refer to the types of parameters; for example, attributes of common configurations include subcarrier spacing, cyclic prefix length, parameter set, or symbol length, while attributes of dedicated configurations include, for example, time-domain start position, time length, frequency-domain position information, or bandwidth. Furthermore, replacement can refer to deleting existing configurations and / or attributes and adding new configurations and / or attributes.
[0250] Table 1
[0251] It is understood that the second information can be used to update multiple public configurations and / or multiple private configurations. Optionally, the multiple public configurations may include a first public configuration, and the multiple private configurations may include a first private configuration. For example, the second information can also be used to update a second public configuration and / or a second private configuration. The second information may include an index of the second public configuration. Additionally, the second information may include updated second configuration information and / or updated third configuration information. Alternatively, the second information may include updated second public configurations and / or updated second private configurations.
[0252] Optionally, the second information can be carried in either the second frequency band or the first frequency band, without specific limitations. As one possible implementation, the second information can be carried in the second frequency band, i.e., in a frequency band supported by the first communication system, such as the licensed frequency band of the first communication system. As shown in Figure 10, the first device can send common configuration #1 (index CommonIndex = 0), dedicated configuration #1, and dedicated configuration #2 through the second frequency band. Dedicated configuration #1 carries the index CommonIndex = 0 of the common configuration, meaning dedicated configuration #1 is associated with common configuration #1. When it is necessary to update common configuration #1, the first device can send update instruction #1 through the second frequency band, where update instruction #1 can carry CommonIndex = 0. Additionally, when it is necessary to update dedicated configuration #1, the first device can send update instruction #2 through the second frequency band, where update instruction #2 can carry CommonIndex = 0, indicating that dedicated configuration #1 is being updated.
[0253] As another possible implementation, the second information can be carried in the first frequency band, that is, the frequency band where the first communication system and the second communication system coexist. Specifically, if the second information is carried in the first frequency band, it can be carried in the transmission resources of the first communication system within that band. For example, the second information can be carried in an SS-BWP configured through the first information or similar SS-BWP configuration information. Referring again to Figure 10, the update instruction #2 used to update dedicated configuration #1 can also be carried in the transmission resources corresponding to dedicated configuration #2.
[0254] For cellular network systems, the second information can be carried in one or more of the following: RRC message, MAC CE, or DCI. Alternatively, the second information can also be carried in the BWP instruction, without specific limitations.
[0255] Optionally, the second device may receive third information (or an activation indication), which can be used to indicate that the first transmission resource is an active transmission resource. The third 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 third information. Taking SS-BWP as an example, the third information can specifically be used to indicate that SS-BWP, as the first transmission resource, is an active BWP.
[0256] Specifically, the third information may include an index and / or resource information of the first transmission resource. The index of the first transmission resource may be related to the index of the first common configuration and / or the index of the first dedicated configuration. Resource information may include, for example, the first common configuration, such as frequency domain information and / or time domain information, as described in S101. In other words, in this application, the activation instruction may carry the index and / or resource information of the activated SS-BWP to indicate the activated SS-BWP.
[0257] When the third information includes an index of the first transmission resource, the third information can be an SS-BWP activation identifier (SS-BWP-activateID) field. The SS-BWP activation identifier field can be used to carry an index of the activated SS-BWP. This field can be carried in the BWP indication or in newly added signaling. This newly added signaling can be, for example, the SS-BWP-set field. For SS-BWPs in a communication system, the newly added signaling can be carried in RRC messages, MAC CE, or DCI, without specific restrictions.
[0258] For example, the second device obtains SS-BWP-set = {SS-BWP Index i, SS-BWP Index j, ..., SS-BWP Index k} from the first information or existing frequency bands. The third information is the SS-BWP-activateID field, which can carry index j to indicate that the activated SS-BWP is the SS-BWP with index j.
[0259] It is understandable that the index of the active SS-BWP can be carried in the same signaling (or message or field) as the indexes of multiple allocated SS-BWPs. As an example of merging the transmission of first and third information, as described in S101 regarding the first information, the first information can carry the indexes of multiple allocated SS-BWPs, and can further carry the third information, i.e., the index of the active SS-BWP, within the first information. For example, the first information carries SS-BWP-set={j,SS-BWP Index i,SS-BWP Index j,…,SS-BWP Index k}, where j represents the active SS-BWP with index j, and SS-BWP Index i, SS-BWP Index j,…,SS-BWP Index k respectively represent multiple allocated SS-BWPs with indices i, j…k.
[0260] This can also be understood as the first and third information being merged into a single message. This merged message can contain the index of the active SS-BWP and the indices of multiple allocated SS-BWPs. Alternatively, the first and third information can be merged and sent together. For example, the merged message might carry an SS-BWP-set = {j, SS-BWP Index i, SS-BWP Index j, ..., SS-BWP Index k}.
[0261] Furthermore, the index of the activated SS-BWP can also be sent independently of the indexes of the multiple allocated SS-BWPs; in other words, the first message can be sent independently of the third message.
[0262] In addition, the indexes of the multiple SS-BWPs allocated can also be carried in traditional frequency bands.
[0263] Optionally, the third information may also include indexes and / or resource information of other activated transmission resources, meaning the third 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.
[0264] In one possible embodiment, the third 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 third 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 traditional frequency band (such as a licensed frequency band) or a coexisting frequency band. The coexisting frequency band can be a previously activated SS-BWP.
[0265] As shown in Figure 11, the dashed rectangles represent the positions of SS-BWPBs in the first communication system, and the time-limited positions represent the positions of SS-BWPs activated at different times. As indicated by the arrows, the activated SS-BWP 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 shown in number ① is considered the first transmission resource, then the third information can be carried in the licensed frequency band. Furthermore, the activated SS-BWP shown in number ② can be activated by activation indication #2 carried by the activated SS-BWP shown in number ①. That is, still considering the activated SS-BWP shown in number ① as the first transmission resource, the first device can send fourth information (i.e., activation indication #2) in this first transmission resource. The fourth information is used to indicate the next activated SS-BWP (such as the fourth transmission resource). The difference is that they are used to activate different SS-BWPs. Moreover, if the activated SS-BWP shown in number ① is considered the first transmission resource, then the third information (i.e., activation indication #2) can be carried in the coexisting frequency band.
[0266] Similarly, if the first transmission resource is the transmission resource of the second communication system, then the third 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.
[0267] It is understandable that the third 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 third information can be sent by different network devices. Taking the third 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 third information through the transmission resources of the first communication system and needs to send the third 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.
[0268] Furthermore, in scenarios where the location of the second device changes, the first and third messages can be sent by different network devices within the same communication system. For example, the first message may be sent by network device #1 to which the second device is connected. If the second device moves, the SS-BWP configured in the first message may still be valid, and network device #2 can send the third message to the second device to activate the first transmission resource.
