Description

Communication methods, devices, equipment and storage media

[0001] This application claims priority to Chinese Patent Application No. 202410709718.1, filed on May 31, 2024, entitled "Communication Method, Apparatus, Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, apparatus, device, and storage medium. Background Technology

[0003] In real-world communication scenarios, different (or different types of) communication systems may be deployed on the same frequency. In other words, different communication systems may conduct their respective communication transmissions on the same frequency band. For example, the International Mobile Telecommunications (IMT) system and the Wireless Fidelity (Wi-Fi) communication system coexist on the same frequency in the 6GHz band.

[0004] When different communication systems transmit data on the same frequency band, interference between them will occur. Therefore, how to suppress interference between different communication systems through device interaction, and thus achieve spectrum sharing, is a pressing issue that needs to be addressed. Summary of the Invention

[0005] This application provides a communication method, apparatus, device, and storage medium to suppress interference between two different types of communication systems, thereby solving the problem that the two communication systems cannot share spectrum.

[0006] In a first aspect, embodiments of this application provide a communication method, which can be executed by a first communication device. The first communication device can be implemented as a communication device (such as a Wi-Fi device) or a component in a communication device, such as a chip, a chip system, etc.

[0007] In this method, a first communication device receives a first reference signal from a second communication device, wherein the first and second communication devices are applied to different types of communication systems, and the first communication device sends channel state information (CSI) to the second communication device. The CSI is used to process the data transmission of the second communication device to avoid communication interference between the second and first communication devices, and to achieve spectrum sharing when the first and second communication devices are deployed on the same frequency.

[0008] In one possible implementation, the second communication device is used to implement the communication functions of at least two types of communication systems.

[0009] In one possible implementation, the first communication device is used to implement the communication function of a first type of communication system, wherein the first type does not belong to at least two types.

[0010] In the first design, the first reference signal may include a channel status information reference signal (CSI-RS); in the second design, the first reference signal may include a synchronization signal block (SSB). In the first design, because CSI-RS provides more comprehensive coverage of time and frequency resources, the channel status information obtained by the first communication device based on CSI-RS measurements is more accurate. In the second design, using an SSB as the first reference signal helps save on interactive signaling overhead and reduces the processing complexity of the communication system.

[0011] In the first design described above, one possible implementation is as follows: the first communication device sends a request message to the second communication device, the request message being used to request a first reference signal. This request message is used to request the measurement of the channel between the second communication device and the second communication device, so as to reduce or eliminate communication interference between the two communication devices based on the measurement results.

[0012] In the first design described above, one possible implementation is as follows: the first communication device can receive a second reference signal from the second communication device. The second reference signal is used to measure the reference signal received power (RSRP) of the second communication device. When the RSRP is greater than or equal to a preset value, the communication device sends a request message to the second communication device to avoid performing interference suppression operation when the interference of the second communication device to the first communication device is weak, which is beneficial to saving communication resources.

[0013] In the second design described above, one possible implementation is as follows: the first reference signal is also used to measure the RSRP corresponding to the first communication device; the first communication device sends channel state information to the second communication device, including: when the RSRP is greater than or equal to a preset value, the first communication device sends channel state information to the second communication device, so as to avoid performing interference suppression operation when the interference of the second communication device to the first communication device is weak, which is conducive to saving communication resources.

[0014] Optionally, the communication device receives indication information from the second communication device. The indication information indicates whether the channel status information has been successfully received. That is, the indication is given when the channel status information is successfully or unsuccessfully received by the second communication device, which helps to improve communication reliability.

[0015] In one possible implementation, the first reference signal carries information about the second communication device, which is used by the communication device to address the second communication device through the core network equipment to enable interaction with communication devices in different types of communication systems.

[0016] In one possible implementation, the channel state information carries information about the communication device, which is used by the second communication device to address the communication device through the core network equipment to enable interaction with communication devices in different types of communication systems.

[0017] Secondly, embodiments of this application provide a communication method, which can be executed by a second communication device. The second communication device can be implemented as a communication device (such as an IMT base station) or a component in a communication device, such as a chip or a chip system.

[0018] For example, the method includes: a second communication device transmitting a first reference signal for channel measurement; the second communication device receiving channel state information from a first communication device; and the second communication device processing data transmission based on the channel state information; wherein the first communication device and the communication device are applied to different types of communication systems.

[0025] In the second design described above, the first reference signal is also used to measure the RSRP corresponding to the first communication device; the second communication device receives channel state information from the first communication device, including: the second communication device receives channel state information sent by the first communication device when the RSRP is greater than or equal to a preset value.

[0026] Optionally, the second communication device sends an indication message to the first communication device, indicating whether the channel status information has been successfully received.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The communication method provided in this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5th Generation (5G) mobile communication systems, 5G-Advanced (5.5G) mobile communication systems, New Radio Access Technology (NR), or 6th Generation (6G) mobile communication systems. Among these, 5G mobile communication systems can include non-standalone (NSA) and / or standalone (SA) networks.

[0057] The communication method provided in this application can also be applied to machine-type communication (MTC), long-term evolution-machine (LTE-M) communication, device-to-device (D2D) networks, machine-to-machine (M2M) networks, Internet of Things (IoT) networks, or other networks. IoT networks may include, for example, vehicle-to-everything (V2X) networks.

[0058] The communication method provided in this application embodiment can also be applied to wireless local area network (WLAN) systems, such as Wi-Fi. The method provided in this application embodiment can be applied to the IEEE 802.11 series protocols, such as 801.11, 802.11b, 802.11a / g, 802.11n, 802.11ac, 802.11ax protocols, and next-generation protocols, etc., and will not be listed further. The technical solution provided in this application embodiment can also be applied to wireless personal area networks (WPANs) based on millimeter wave (MMW) and ultra-wideband (UWB) technologies. The method provided in this application embodiment can be applied to the IEEE 802.15 series protocols, such as 802.15.4a, 802.15.4z, or 802.15.4ab protocols, or a future generation of UWB WPAN protocols, etc., and will not be listed further.

[0059] The communication method provided in this application can also be applied to satellite communication systems.

[0060] The communication method provided in this application embodiment can also be applied to open radio access networks (O-RAN).

[0061] The communication method provided in this application can also be applied to future communication systems. This application does not limit this application.

[0062] In this application embodiment, the RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access the communication system wirelessly. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next-generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access point (AP) in a WLAN system. The RAN node can be a macro base station, a micro base station, an indoor station, a relay node, or a donor node. The RAN node can also be an IMT base station. An IMT base station refers to a base station used for international mobile telecommunications (IMT). IMT is a series of global mobile communication technology standards defined by the International Telecommunication Union (ITU), covering multiple generations and future mobile communication technologies.

[0063] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). The RU can be included in radio frequency equipment, such as in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0064] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes. For ease of description, a base station is used as an example of a RAN node in the following description.

[0065] In a WLAN system, the RAN node can be an Access Point (AP). An AP supports communication or sensing using WLAN protocols and has the function of communicating or sensing with other devices in the WLAN network (such as non-access point stations (non-AP STAs) or other access points). It can also have the function of communicating or sensing with other devices. Alternatively, an access point acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. In a WLAN system, an access point can be called an Access Point Station (AP STA). This device with wireless communication capabilities can be a complete device, or it can be a chip, processing system, or functional module installed in a complete device. Devices with these chips, processing systems, or functional modules can implement the methods and functions of the embodiments of this application under the control of the chips, processing systems, or functional modules. The AP in the embodiments of this application is a device that provides services to non-AP STAs and can support 802.11 series protocols or subsequent protocols. For example, an access point can be an access point for a terminal (such as a mobile phone) to enter a wired (or wireless) network, mainly deployed in homes, buildings, and parks, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. Another example is that an AP can be a communication entity such as a communication server, router, switch, or bridge; APs can include various forms of macro base stations, micro base stations, and repeater stations. Of course, an AP can also be a chip, processing system, or module within the above-mentioned devices, thereby implementing the methods and functions of the embodiments of this application.

[0066] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from RAN nodes. Terminals can also be referred to as terminal equipment, user equipment (UE), mobile stations, mobile terminals, etc. RAN nodes and terminals can be fixed or mobile. RAN and terminals 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 base station and terminal.

[0067] In a WLAN system, a terminal can be a station (STA). An STA is a device with wireless communication capabilities, supporting communication or sensing using the WLAN protocol, and having the ability to communicate or sense with other non-AP STAs or access points in the WLAN network. In a WLAN system, a station can be called a non-access point station (non-AP STA). For example, an STA is any user communication device that allows a user to communicate or sense with an AP and thus communicate with the WLAN. This device with wireless communication capabilities can be a complete device, or it can be a chip, processing system, or functional module installed in a complete device. Devices with these chips, processing systems, or functional modules can implement the methods and functions of the embodiments of this application under the control of the chips, processing systems, or functional modules. For example, an STA can be a wireless communication chip, a wireless sensor, or a wireless communication terminal, and can also be called a user. Furthermore, an STA can be a mobile phone supporting Wi-Fi communication, a tablet computer supporting Wi-Fi communication, a set-top box supporting Wi-Fi communication, a smart TV supporting Wi-Fi communication, a smart wearable device supporting Wi-Fi communication, an in-vehicle communication device supporting Wi-Fi communication, and a computer supporting Wi-Fi communication. Of course, STA can also be a chip, processing system, or module in the various types of devices described above, thereby implementing the methods and functions of the embodiments of this application.

[0068] In this embodiment of the application, Wi-Fi AP and Wi-Fi STA can be collectively referred to as Wi-Fi devices.

[0069] In this application, the RAN node sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the RAN node, with the uplink information carried on the uplink channel. To communicate with the RAN node, the terminal needs to establish a radio connection on a cell controlled by the RAN node. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with this serving cell, it is also susceptible to interference from signals from neighboring cells.

[0070] The embodiments of this application can be applied to at least two different types of communication systems to achieve interference suppression between different types of communication systems. The types of communication systems can be classified, for example, based on the communication technology used, or based on the different communication standards listed above, such as the 6G communication system and the WLAN system mentioned above being different types of communication systems.

[0071] The communication system applied in the embodiments of this application will be described exemplarily below with reference to Figures 1a and 1b. It should be noted that this application does not limit the deployment area of ​​different types of communication systems (such as a first communication system and a second communication system). In Figure 1a, the first communication system 110a and the second communication system 120a are deployed at intervals, with a distance between them; in Figure 1b, the first communication system 110b and the second communication system 120b are deployed without intervals, that is, the first communication system 110b and the second communication system 120b are deployed in the same area.

[0072] In Figure 1a, the first communication system 110a may include one or more RAN nodes and one or more terminals. In Figure 1b, the second communication system 120a may include one or more RAN nodes and one or more terminals. Taking the first communication system 110a as a WLAN system and the second communication system as a mobile communication system (such as a 5G, 5.5G, or 6G mobile communication system) as an example, the RAN nodes in the first communication system 110a may be Wi-Fi APs, and the terminals may be Wi-Fi STAs. The RAN nodes in the second communication system 120a may be used to implement the communication functions of one or more communication systems. When the RAN node can be used to implement the communication functions of two or more mobile communication systems, it may be an IMT base station. The second communication system 120a may also include core network equipment not shown in Figure 1a. The core network equipment and the RAN nodes may be independent and different physical devices, or they may be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN nodes.

[0073] The first communication system 110b in Figure 1b has the same or similar implementation as the first communication system 110a in Figure 1a. Similarly, the second communication system 120b in Figure 1b has the same or similar implementation as the second communication system 120a in Figure 1a. For the sake of brevity, these details will not be repeated.

[0074] The embodiments of this application do not limit the number of RAN nodes and terminals in the communication system (such as the first communication system and / or the second communication system), and the embodiments of this application also do not limit the number of communication systems, for example, they may also include a third communication system, etc.

[0075] The aforementioned first and second communication systems may experience communication interference due to co-frequency deployment. For example, when the 6GHz band spectrum is designated for use by IMT base stations and other mobile devices, Wi-Fi devices may need to co-exist with IMT base stations on the 6GHz band. However, in this scenario, Wi-Fi devices will be subject to interference from the radio signals emitted by the normally functioning IMT base stations. When the interference signal energy from the IMT base station exceeds the Wi-Fi device's own energy detection threshold, the Wi-Fi device will choose to use another frequency band or reduce its modulation and coding scheme (MCS) to continue using the channel for transmission. Switching to another channel reduces the Wi-Fi device's spectrum resource utilization, and reducing MCS transmission affects the Wi-Fi device's communication quality. Consequently, the two systems may be unable to share spectrum.

[0076] The above description only uses the communication interference between Wi-Fi devices and IMT base stations as an example, but this application does not limit it. For example, there may also be communication interference between satellite base stations and terminals in the satellite communication system and IMT base stations. Communication interference between other communication systems will not be listed here.

[0077] It should be understood that the first communication system, or the first type of communication system, includes a first communication device, and the second communication system, or the second type of communication device, may include a second communication device. Interference may exist between the first and second communication devices due to issues such as co-frequency deployment. For example, the downlink transmission of the second communication device may interfere with the downlink or uplink transmission of the first communication device. Taking an IMT base station as the second communication device and a Wi-Fi AP as the first communication device as an example, when the IMT base station sends downlink signals to terminals within the cell, it interferes with the downlink signals sent by the Wi-Fi AP to the Wi-Fi STA; or when the IMT base station sends downlink signals to terminals within the cell, it interferes with the uplink signals received by the Wi-Fi AP from the Wi-Fi STA. Similarly, when the IMT base station sends downlink signals to terminals within the cell, it interferes with the uplink signals sent by the Wi-Fi STA to the Wi-Fi AP; or when the IMT base station sends downlink signals to terminals within the cell, it interferes with the downlink signals received by the Wi-Fi STA from the Wi-Fi AP. This application only illustrates the example of communication interference occurring during the downlink transmission of the second communication device, and does not limit it to other applications. For example, the uplink transmission of the second communication device may cause communication interference to the downlink or uplink transmission of the first communication device.

[0078] To address the aforementioned technical issues, in this embodiment of the application, the first communication device performs channel measurement based on a reference signal (hereinafter referred to as the first reference signal) sent by the second communication device, and sends the measured channel state information to the second communication device, so that the second communication device can process data transmission based on the channel state information, thereby avoiding communication interference between the first and second communication devices and achieving spectrum sharing.

[0079] It should be noted that, in the embodiments of this application, the first communication device and the second communication device need to establish an interactive link to realize the interaction between the communication systems. Taking a Wi-Fi device and an IMT base station as an example, communication modules for realizing the above-mentioned interactive link can be deployed between the Wi-Fi device and the IMT base station respectively. Optionally, the Wi-Fi device and the IMT base station can realize communication transmission through the core network, as will be described in detail below.

[0080] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence, such as distinguishing different communication devices, reference signals, etc. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0081] To facilitate understanding of the methods provided in the embodiments of this application, the terminology involved in this application will be explained by way of example below.

[0082] 1. Beam: A beam is the main lobe of the radiation pattern of an antenna or antenna array, formed by the superposition of signals radiated from each antenna module. A transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while a receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna. One or more antenna ports can be used to form a beam for transmitting reference signals, data channels, control channels, or probe signals, etc.

[0083] In protocols, beamforming can be represented by spatial filters, spatial parameters, or transmission methods and modes. Transmission methods represent digital weighting and / or analog weighting. Different transmission methods correspond to different digital weights, different analog weights, or combinations of different digital and analog weights. In practical communication systems, beamforming can be characterized by resources (or signals, reference signals, port groups).

[0084] 2. Beamforming: Also known as beamforming technology. With the development of Multiple Input Multiple Output (MIMO) technology, both the transmitting and receiving ends can use multiple antennas to transmit and receive signals, thereby obtaining diversity gain, achieving spatial multiplexing, and obtaining higher transmission rates. However, due to the interference and diffraction of electromagnetic waves, the electromagnetic wave signals transmitted by multiple antennas may have different phases. After superposition, electromagnetic waves with different phases are enhanced in some directions and weakened in others. The essence of beamforming lies in changing the amplitude and phase of the signal from each transmitting antenna, so that the superposition effect of multiple antennas, in space, appears as a beam aligned in specific directions. That is, the energy is concentrated in a few directions, while it is zero or close to zero in most of the space.

[0085] 3. Reference signal: also known as pilot signal, which can be used for channel measurement, channel estimation or beam quality monitoring, etc. According to LTE or NR protocols, uplink reference signals may include, for example, sounding reference signal (SRS), physical uplink control channel (PUCCH)-demodulation reference signal (DMRS), physical uplink share channel (PUSCH)-demodulation reference signal (PUSCH-DMRS), phase noise tracking reference signal (PTRS), uplink positioning signal (RS), etc.; downlink reference signals may include, for example, SSB, physical downlink control channel (PDCCH)-demodulation reference signal (PDCCH-DMRS), physical downlink share channel (PDSCH)-demodulation reference signal (PDSCH-DMRS), PTRS, CSI-RS, cell reference signal (CRS) in LTE, tracking reference signal (TRS) in NR, downlink positioning signal (RS), etc.

[0086] In this embodiment, downlink channel measurement needs to be implemented. For example, if the second communication device is an IMT base station and the first communication device is a Wi-Fi device, the downlink reference signal can be used. For instance, the reference signal could be CSI-RS or SSB used in downlink channel measurement. Alternatively, downlink channel measurement can be performed using the uplink reference signal based on channel reciprocity. For example, the reference signal could be SRS, etc. This application does not limit this; for example, uplink channel measurement can also be achieved through the interaction of the first and second communication devices. During channel measurement, the reference signal can be any known signal from both the transmitting and receiving ends.

[0087] Channel state information (CSI) obtained from reference signal measurements can include: precoding matrix indicator (PMI), channel quality indicator (CQI), rank indicator (RI), layer indicator (LI), RSRP, reference signal reception quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference-noise ratio (SINR), beam angle of arrival, beam ID, etc. The specific quantities of CSI fed back by the first communication device can be determined according to the configuration, as shown in the CSI reporting configuration below.

[0088] 4. Reference Signal Configuration: Reference signal configuration can include reference signal type configuration, reference signal function configuration, reference signal resource configuration, reference signal reporting configuration, and reference signal resource configuration. The following section, using Table 1 as an example, describes the CSI-RS configuration.

[0089] Table 1

[0090] Referring to Table 1, the configuration information for CSI-RS may include information on configuring the CSI-RS type. The CSI-RS type may include, but is not limited to: NZP CSI-RS, CSI-IM, and ZP CSI-RS.

[0091] When the CSI-RS configuration information indicates that the CSI-RS type is NZP CSI-RS, the CSI-RS configuration information may also include CSI-RS function configuration, resource set configuration, reporting configuration, and resource configuration. Among these, the CSI-RS resource configuration can configure resources as periodic / periodic / semi-static resource mapping (QCL), etc. The functions of the CSI-RS may include: tracking, mobility, and channel measurement. When configuring CSI-RS as NZP CSI-RS and configuring tracking functionality, the resource set configuration in the CSI-RS configuration information can include resource sets that satisfy trs-info, indicating that all NZP-CSI-RS resources in the resource set have the same antenna port. The reporting configuration can be configured to not report. When configuring CSI-RS as NZP CSI-RS and configuring beam management functionality, the resource set configuration in the CSI-RS configuration information can configure whether to use repeating beams or the same beams for transmission. The reporting configuration can be configured to report CRI or not. When configuring CSI-RS as NZP CSI-RS and configuring beam management functionality, the resource set configuration in the CSI-RS configuration information can configure resource sets for CSI-RS resource mobility. The reporting configuration can be configured to report L1-RSRP. When configuring CSI-RS and channel measurement function, the resource set configuration in the CSI-RS configuration information can be configured to have no TRS-info resource set and not use repeated beams or the same beams for transmission. The reporting configuration can be configured to report CQI, PMI, RI, LI, etc.

[0092] When the CSI-RS configuration information indicates that the CSI-RS type is CSI-IM, the CSI-RS configuration information may also include CSI-IM resource signaling to configure periodic / aperiodic / semi-static resource mapping, etc. When the CSI-RS configuration information indicates that the CSI-RS type is ZP CSI-RS, the CSI-RS configuration information may include PDSCH config signaling to configure periodic / aperiodic / semi-static resource mapping, etc.

[0093] In addition, the configuration information for each feature must also include time and frequency resource information that conforms to the 3GPP NR protocol, such as the mode, density, port configuration, and transmission period of the CSI-RS signal.

[0094] It should be noted that the configuration information shown in Table 1 above is only an example and does not constitute any limitation on this application. In actual communication scenarios, the configuration information of CSI-RS may include more or less content than that in Table 1.

[0095] For example, when configuring CSI-RS to implement channel measurements, the CSI feedback may include: RI, CQI, PMI, layer indicator (LI), RSRP, reference signal reception quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference-noise ratio (SINR), etc. The specific quantities in the feedback CSI can be determined according to the configuration, such as through the reporting configuration signaling (e.g., CSI-ReportConfig) mentioned above.

[0096] It should also be understood that the above resources may include time-domain resources, frequency-domain resources, or time-frequency resources, wherein time-frequency resources may be resources allocated in units of resource elements (REs).

[0097] The method provided in this application will be described in detail below with reference to the accompanying drawings. In the embodiments described below, the interaction between the first communication device and the second communication device to achieve communication interference between communication systems is used as an example. As mentioned earlier, the first communication device and the second communication device are applied to different types of communication systems. For example, the first communication device is applied to a first type of communication system, and the second communication device is applied to a second type of communication system. The first communication device may be, for example, a Wi-Fi device (such as a Wi-Fi AP or Wi-Fi STA) in the first communication system 110b in FIG1a or FIG1b, or a component in the Wi-Fi device, such as a chip, a chip system, or a functional module that can implement the method provided in the embodiments of this application; the second communication device may be, for example, an IMT base station in the second communication system 120b in FIG1a or FIG1b, or a component in the IMT base station, such as a chip, a chip system, or a functional module that can implement the method provided in the embodiments of this application.

[0098] Figure 2 is a schematic flowchart of a communication method provided in an embodiment of this application. Descriptions of the first communication device and the second communication device, etc., can be found above and will not be detailed here. Referring to Figure 2, method 200 includes:

[0099] S210, the second communication device sends a first reference signal, and correspondingly, the first communication device receives the first reference signal from the second communication device.

[0100] S220, the first communication device sends channel status information to the second communication device, and correspondingly, the second communication device receives the channel status information sent by the first communication device.

[0101] S230, the second communication device processes the data transmission based on channel state information.

[0102] The first reference signal can be any of the reference signals in the examples described above. In S210 above, the second communication device can broadcast the first reference signal over the air interface, or the second communication device can send the first reference signal through the interactive link between the first type of communication system and the second type of communication system.

[0103] As a first example, the first reference signal may include, for example, an SSB, which may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). The PSS can be used for frequency synchronization and coarse time synchronization; the SSS can be used for precise time synchronization and physical cell ID detection; the PBCH can be mapped from a master information block (MIB), for example, the MIB is mapped to a broadcast control channel (BCCH) and carried on the broadcast channel (BCH), and then the BCH is mapped to the PBCH. The MIB may include relevant configuration parameters of system information block (SIB) 1, such as parameters used to configure control resource set (CORESET) #0, meaning the PBCH carries channel configuration information.

[0104] In the SSB, the resources occupied by PSS, SSS, and PBCH can be flexibly configured. For ease of understanding, the configuration of SSB is shown in Figure 3. Referring to Figure 3, the SSB occupies a total of 4 orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 240 subcarriers in the frequency domain, with subcarrier numbers ranging from 0 to 239, which corresponds to 20 physical resource blocks (PRBs). The time-frequency resource block numbers occupied by the SSB range from 0 to 19. In Figure 3, the two ends of the frequency domain resources occupied by PSS and SSS are set to zero for the subcarriers, serving as guard bands for PSS and SSS to suppress subcarrier interference.

[0105] Continuing with the first example above, S210 can be specifically implemented as follows: the second communication device can broadcast the SSB, the first communication device detects the SSB, and then decodes the SSB to complete reception. The first communication device can perform channel measurement based on the SSB to obtain channel state information. For example, the first communication device can perform channel measurement based on the channel configuration information carried by the PBCH to obtain channel state information.

[0106] As a second example, the first reference signal may, for example, include a CSI-RS. For instance, the CSI-RS includes information for implementing at least one function in channel measurement or beam management. Continuing with this second example, the second communication device can send the CSI-RS to the first communication device. After receiving the CSI-RS, the first communication device measures the channel from the second communication device to the first communication device based on the information in the CSI-RS to obtain channel state information. Since the first and second communication devices are used in different types of communication systems, it is difficult for them to communicate directly over the air interface. In this case, the second communication device can send the CSI-RS through an interactive link. For example, the second communication device can address the first communication device in the core network, that is, send the CSI-RS to the first communication device through core network equipment. The following will provide an exemplary description of constructing an interactive link.

[0107] Based on the first or second example above, the channel state information measured by the first communication device may be, for example, CSI. The channel state information may include any one or more of the CSI information described in the preceding examples. For instance, to facilitate data transmission processing by the second communication device and avoid communication interference between the second and first communication devices, the channel state information may include, but is not limited to, at least one of the following: PMI; spatial domain angle of arrival information of the beam scan (or illumination) of the second communication device onto the side of the first communication device; beam information, which may include information about the strongest beam received by the first communication device from the second communication device, such as the beam identifier (ID); CQI.

[0108] Further, the first communication device sends channel state information to the second communication device. Optionally, the first and second communication devices can transmit the channel state information via an interactive link. For example, the first communication device can address the second communication device in the core network and then send the channel state information to the second communication device through the core network equipment. The following will provide an exemplary description of constructing the interactive link. The second communication device processes data transmission in response to the received channel state information. For example, in a MIMO scenario, the data transmission processing may include beam adjustment; for instance, the second communication device can adjust the downlink beam according to the channel state information to avoid communication interference with the first communication device during downlink transmission.

[0109] In one example, the second communication device can perform beam adjustment on the beam indicated by the beam information in the channel state information (such as the beam with the strongest energy) to adjust the beam to avoid direct beam exposure or reduce beam energy radiation to the location of the first communication device.

[0110] In another example, the second communication device can adjust the precoding weights of the downlink beam based on the PMI in the channel state information, thereby adjusting the downlink beam to avoid direct beaming or reduce beam energy radiation to the location of the first communication device.

[0111] In another example, the second communication device can calculate the precoding in the direction of the first communication device based on the angle of arrival indicated in the channel state information, and adjust the precoding weight of the downlink beam by using the calculated precoding, thereby adjusting the downlink beam to avoid direct or reduce the beam energy radiation to the location of the first communication device.

[0112] It should be understood that the various beam adjustment methods in the above examples can be combined to improve the accuracy of beam adjustment.

[0113] Therefore, in this embodiment of the application, for the first communication device and the second communication device applied to different types of communication systems, the first communication device receives a first reference signal sent by the second communication device, performs channel measurement based on the first reference signal to obtain channel state information, and then sends the measured channel state information to the second communication device. The second communication device performs data transmission processing based on the received channel state information to avoid communication interference between the second communication device and the first communication device, and achieves spectrum sharing when the first communication device and the second communication device are deployed on the same frequency.

[0114] The following is an example of how to construct an interaction link.

[0115] The first communication device can decode the reference signal sent by the second communication device to obtain information about the cell covered by the second communication device, such as the cell's PCI. For example, referring to Figure 4, when the second communication device may cause communication interference to the first communication device, the first communication device can detect the SSB broadcast by the second communication device and decode the PSS and SSS in the detected SSB to obtain the PCI carried by the SSB. Then, based on the information of the cell covered by the second communication device, the first communication device can transmit data to the second communication device through the core network equipment, such as sending channel state information. Furthermore, in subsequent data transmission processes, both the first and second communication devices can carry their respective information so that the other side can achieve addressing transmission through the core network equipment based on the information of the carried communication device, thereby maintaining the interactive link.

[0116] Optionally, the information carried by the first communication device in data transmission for addressing the first communication device includes, but is not limited to, at least one of the following:

[0117] 1. Service Set Identifier (SSID) of the first communication device. The first communication device translates the SSID into an address that can be addressed in the core network before it enters the core network, or the core network device can translate the received SSID into an address that can be addressed in the core network, so as to realize data transmission and message exchange in the core network.

[0118] 2. The Internet Protocol (IP) address of the first communication device, which can be directly used for data transmission and message exchange in the core network.

[0119] 3. The Media Access Control (MAC) address of the first communication device. The first communication device can translate the MAC address into an address that can be addressed in the core network before the MAC address enters the core network, or the core network device can translate the received MAC address into an address that can be addressed in the core network, so as to realize data transmission and message interaction in the core network.

[0120] Optionally, the information carried by the second communication device in data transmission for addressing the second communication device includes, but is not limited to, at least one of the following:

[0121] 1. PCI of the cell covered by the second communication device.

[0122] 2. The IP address of the second communication device.

[0123] The following will provide an exemplary description of the communication process between the first communication device and the second communication device, using SSB and CSI-RS as examples respectively.

[0124] Figure 5 is a schematic diagram of the interaction flow of a communication method provided in an embodiment of this application. Descriptions of the first communication device and the second communication device, etc., can be found above and will not be detailed here. When the first reference signal includes CSI-RS, this embodiment is implemented in conjunction with an embodiment that constructs an interaction link based on SSB, and may include at least S310, S330 to S350 and S370 as shown in Figure 5.

[0125] In S310, the second communication device sends a second reference signal, and correspondingly, the first communication device receives the second reference signal from the second communication device. For example, the second reference signal may include an SSB, which the second communication device broadcasts. The first communication device receives the SSB by detecting it and decodes it to obtain the PCI of the second communication device.

[0126] For example, if the first communication device can detect the SSB, it will consider the second communication device that sent the SSB as a communication device that is interfering with its communication. In this case, in S330, the first communication device can send a request message to the second communication device through the core network device. Correspondingly, the second communication device receives the request message from the first communication device through the core network device. The request message is used to request a first reference signal, or in other words, the request message is used to request the measurement of the channel between the second communication device and the first communication device, so as to eliminate or reduce the communication interference between the second communication device and the first communication device based on the measurement results.

[0127] The request information may include information about the first communication device, so that when the second communication device sends the first reference signal through the core network equipment, it can address the first communication device in the core network based on the information of the first communication device. The information of the first communication device can be found in the description in the preceding example, and will not be repeated here for the sake of brevity.

[0128] Optionally, the request information may include configuration information for the first reference signal, i.e., CSI-RS configuration information. The CSI-RS configuration information may include any one or more of the methods described in the foregoing examples. For instance, the CSI-RS configuration information may at least include: information configuring an NZP CSI-RS type CSI-RS. Optionally, the CSI-RS configuration information may further include at least one of the following: information for configuring channel measurements, information for configuring beam management, information for mobility measurements, or information for tracking. Optionally, the CSI-RS configuration information may also include information configuring the time-frequency resources of the CSI-RS.

[0129] In S340, the second communication device can address the first communication device in the core network based on the information of the first communication device carried in the request information, so as to send a first reference signal to the first communication device through the core network equipment. Correspondingly, the first communication device can receive the first reference signal from the second communication device through the core network equipment. The implementation of S340 is similar to S210 in the embodiment shown in FIG2. Based on this, in this embodiment, the first reference signal sent by the second communication device may also include the information of the second communication device, so that the first communication device can address the second communication device in the core network based on the information of the second communication device in subsequent transmission. The information of the second communication device can be referred to the description in the previous example, and will not be repeated for the sake of brevity. It is understood that when the first reference signal carries the PCI of the second communication device, the PCI carried by the first reference signal is the same as the PCI carried by the second reference signal.

[0130] In S350, the first communication device can address the second communication device in the core network based on the information of the second communication device carried by the first reference signal, so as to send channel state information to the second communication device through the core network equipment. Correspondingly, the second communication device can receive the channel state information from the first communication device through the core network equipment. The implementation of S350 is similar to S220 in the embodiment shown in FIG2. Based on this, in this embodiment, the channel state information sent by the first communication device may also include the information of the first communication device, so that the second communication device can address it in the core network based on the information of the first communication device in subsequent transmission. The information of the first communication device can be referred to the description in the previous example, and will not be repeated for the sake of brevity.

[0131] S370 in this embodiment is similar to S230 in the embodiment shown in FIG2, and will not be described again for the sake of simplicity.

[0132] In some embodiments, the second reference signal described above can be used to measure RSRP. For example, referring to S320 in FIG5, after receiving an SSB from the second communication device, the first communication device can measure the RSRP based on the SSB, and determine whether the second communication device broadcasting the SSB is causing communication interference to the first communication device itself, or whether it is necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device. Further, if it is determined that the second communication device is causing communication interference to the first communication device, or that it is necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device, the first communication device sends the aforementioned request information to the second communication device, i.e., executes S330; if it is determined that the second communication device is not causing communication interference to the first communication device itself, or that it is not necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device, the first communication device does not send the request information to the second communication device, i.e., does not execute S330, or in other words, does not need to perform interference elimination. Optionally, the first communication device may determine that the second communication device is causing communication interference to the first communication device when the measured RSRP is greater than or equal to a preset value, or in other words, it is necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device; or, if the measured RSRP is less than the preset value, the first communication device may determine that the second communication device is not causing interference to the first communication device, or in other words, it is not necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device.

[0133] Optionally, the preset value can be pre-configured or agreed upon by the protocol. Pre-configuration can refer to configurations made to the first communication device by other devices (such as network devices), or pre-stored in the first communication device.

[0134] Based on the above embodiments, the first communication device measures the RSRP between the second communication device and the first communication device based on the second reference signal, and judges the strength of communication interference between the second communication device and the first communication device based on the RSRP, so as to avoid interacting with the second communication device to eliminate interference when there is no communication interference or the intensity of communication interference is small, thereby saving communication overhead and reducing the processing complexity of the communication device.

[0135] In some embodiments, to improve communication reliability, referring to S360 in FIG5, the second communication device may send indication information to the first communication device to indicate whether the channel state information sent by the first communication device has been successfully received. Exemplarily, this application does not limit the reception feedback mechanism adopted by the second communication device; for example, reception feedback may be based on a NACK-only mechanism or an ACK-NACK mechanism. In the NACK-only mechanism, if the second general-purpose device fails to decode the channel state information from the first communication device, it sends a NACK message; otherwise, it does not send feedback. In the ACK-NACK mechanism, if the second communication device fails to decode the channel state information from the first communication device, it sends a NACK message; if it successfully decodes the channel state information from the sending second communication device, it sends an ACK message. Optionally, the first communication device may initiate retransmission after receiving a NACK message, and may not retransmit the channel state information after receiving an ACK message.

[0136] Figure 6 is a schematic diagram of the interaction flow of a communication method provided in an embodiment of this application. Descriptions of the first communication device and the second communication device, etc., can be found above and will not be detailed here.

[0137] When the first reference signal includes an SSB, this embodiment is implemented in conjunction with an embodiment that constructs an interactive link based on an SSB, and may include at least S410, S430 and S450 as shown in FIG6.

[0138] In S410, the second communication device sends a first reference signal, and correspondingly, the first communication device receives the first reference signal from the second communication device. For example, the second communication device broadcasts the SSB, and the first communication device receives the SSB by detection. On one hand, the first communication device performs channel measurement based on the SSB (such as channel configuration information in the SSB) to obtain channel state information from the second communication device to the first communication device; on the other hand, the first communication device decodes the SSB to obtain the PCI of the second communication device.

[0139] For example, if the first communication device can detect the SSB, it will consider the second communication device that sent the SSB as a communication device that is interfering with its communication. In this case, in S430, the first communication device can address the second communication device in the core network based on the PCI of the second communication device, so as to send the channel state information measured based on the first reference information to the second communication device through the core network equipment. Correspondingly, the second communication device receives the channel state information from the first communication device through the core network equipment, so as to eliminate or reduce the communication interference between the second communication device and the first communication device based on the channel state information.

[0140] S450 in this embodiment is similar to S230 in the embodiment shown in FIG2, and will not be described again for the sake of brevity.

[0141] In some embodiments, the first reference signal received by the first communication device can also be used to measure RSRP. For example, referring to S420 in FIG6, after receiving an SSB from the second communication device, the first communication device can measure the RSRP based on the SSB, and determine whether the second communication device broadcasting the SSB is causing communication interference to the first communication device itself, or whether it is necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device. S420 in FIG6 can be understood by referring to the implementation and technical effects of S320 in FIG5, which will not be repeated for simplicity.

[0142] Continuing with the above embodiments, the first communication device may send channel status information to the second communication device when it is determined that the second communication device is causing communication interference to the first communication device, or when it is necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device, i.e., execute the above-described S430; when it is determined that the second communication device is not causing communication interference to the first communication device itself, or when it is not necessary to eliminate or reduce the communication interference caused by the second communication device to the first communication device, the first communication device does not send channel status information to the second communication device, i.e., does not execute the above-described S430, or in other words, does not need to perform interference elimination for the second communication device.

[0143] In some embodiments, to improve communication reliability, referring to S440 shown in FIG6, the second communication device may send indication information to the first communication device to indicate whether the channel status information sent by the first communication device has been successfully received. S440 has a similar implementation and technical effect to S360 in FIG5, and will not be described in detail for the sake of brevity.

[0144] In the embodiment shown in Figure 5 above, since CSI-RS has comprehensive coverage of time and frequency resources, the first communication device can obtain accurate channel state information by performing channel measurement based on CSI-RS. In the embodiment shown in Figure 6 above, the first communication device can obtain channel state information by performing channel measurement based on SSB while constructing an interactive link based on SSB, which saves the overhead of interactive signaling and reduces the processing complexity of the communication system.

[0145] The method provided by the embodiments of this application has been described in detail above with reference to Figures 2 to 6. The apparatus provided by the embodiments of this application will be described in detail below with reference to Figures 7 and 8.

[0148] When the communication device 700 is used to execute the method of the first communication device side in the above embodiments, the transceiver module 720 can be used to receive a first reference signal from the second communication device. The communication device 700 and the second communication device are applied to different types of communication systems.

The transceiver module 720 is also used to send channel state information to the second communication device.
