Abstract
Description
Technical Field
[0001] This invention relates to the field of communication technology, and specifically to a frame structure configuration method, apparatus, communication device, and storage medium. Background Technology
[0002] With the development of communication technology, 6G systems will provide unprecedented functions and service capabilities. Sensing capabilities will be a key feature of 6G systems, serving not only as the foundation for intelligent network applications but also enhancing the communication system itself and improving system performance. Sensing capabilities will become an inherent capability of mobile communication systems, deeply integrated with communication capabilities. An integrated sensing and communication system refers to the integrated design of communication sensing functions through joint signal design or technologies such as hardware and spectrum sharing. This means that while transmitting information, it analyzes direct, reflected, and scattered radio wave signals to sense information such as the direction, distance, and speed of targets, or to detect, track, identify, and image target devices, events, or environments.
[0003] Currently, sensing is mainly applied in radar systems, and compared to communication, it is designed independently according to different functions and frequency bands. Radar is used for target detection and identification, while communication is used for information transmission between devices. With the development of radar and communication technologies, the differences between the two in operating frequency bands and system composition are becoming smaller, making integrated sensing and communication systems possible.

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0062] The technical solutions of this invention can be applied to various communication systems, such as GSM (Global System of Mobile communication), LTE (Long Term Evolution), or 5G systems. Optionally, a 5G system or 5G network can also be referred to as a New Radio (NR) system or NR network.
[0063] For example, the communication system used in this embodiment of the invention may include network devices and terminal devices (also referred to as terminals, communication terminals, etc.); the network device may be a device that communicates with the terminal device. The network device can provide communication coverage within a certain area and can communicate with terminals located within that area. Optionally, the network device may be a base station in various communication systems, such as an evolved Node B (eNB) in an LTE system, or a gNB in a 5G or NR system.
[0064] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Communication devices may include network devices and terminals with communication functions. Network devices and terminal devices can be the specific devices described above, which will not be repeated here. Communication devices may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities. This embodiment of the present invention does not limit these.
[0065] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0066] This invention provides a frame structure configuration method. Figure 1 This is a flowchart illustrating the frame structure configuration method according to an embodiment of the present invention. Figure 1 ;like Figure 1 As shown, the method includes:
[0067] Step 101: The communication device determines at least one flexible symbol in the frame structure as a sensing symbol, and determines the sensing direction of at least one sensing symbol; the sensing symbol is used to sense target object or environmental information.
[0068] Currently, communication systems configure frame structures on a symbol-by-symbol basis, allowing for more flexible transmission direction configuration. For the 14 symbols in a time slot, there are three configuration methods: uplink transmission, downlink transmission, and flexible transmission. Based on this, this invention adds a new symbol, the sensing symbol, to achieve sensing functionality on the existing frame structure without altering the existing frame structure configuration.
[0069] For example, in this embodiment, the sensing or sensing function refers to the collection of direct, reflected, and scattered signals of radio waves (or signals, sensing signals, etc.), and the acquisition of attribute and state information of the target object or environment by detecting or processing the collected signals. Based on the sensed information, functions such as positioning, ranging, speed measurement, detection, and identification can then be performed. In practical applications, the specific sensing content may be related to the business application scenario.
[0070] In this embodiment, the communication device is a terminal device or a network device.
[0071] In some optional embodiments, when the communication device is a network device, the communication device determines at least one flexible symbol in the frame structure as a sensing symbol, and determines the sensing direction of at least one sensing symbol, including: the network device determines at least one flexible symbol in the frame structure as a sensing symbol and determines the sensing direction of at least one sensing symbol through resource scheduling.
[0072] In this embodiment, when the network device is sensing, whether it is active sensing or passive sensing, the resources used for sensing do not need to be indicated to the terminals within its network coverage area. At least one flexible symbol in the frame structure is determined as a sensing symbol by means of resource scheduling. That is, flexible symbols not used for data transmission are reused as sensing symbols by means of resource scheduling, and the direction of sensing symbols is further specified (or agreed upon, defined) as uplink transmission or downlink transmission.
[0073] In this embodiment, uplink transmission corresponds to sending sensing symbols, and downlink transmission corresponds to receiving response signals of sensing signals or receiving communication signals reflected or scattered by the target object.
[0074] In some alternative embodiments, when the communication device is a terminal device, the communication device determines at least one flexible symbol in the frame structure as a sensing symbol, including: the terminal device receiving first configuration information sent by the network device, and determining at least one flexible symbol as a sensing symbol based on the first configuration information.
[0075] In this embodiment, when the terminal device performs sensing, the network device needs to configure sensing resources for it. Optionally, if the terminal device has sensing capabilities, the terminal device sends a sensing capability reporting result to the network device. After determining that the terminal device has sensing capabilities based on the terminal device's sensing capability reporting result, the network device sends first configuration information to the terminal device.
[0076] In this embodiment, to ensure that the sensing function does not interfere with or preempt normal communication resources, the network device configures flexible symbols not used for data transmission as sensing symbols through signaling configuration, that is, sends first configuration information to the terminal device through signaling. The signaling can be first higher-layer signaling or first physical-layer signaling; for example, the first higher-layer signaling can be RRC signaling, and the first physical-layer signaling can be downlink control information (DCI).
[0077] In some optional embodiments of the present invention, the terminal device receives first configuration information sent by the network device, and determines at least one flexible symbol as a sensing symbol based on the first configuration information, including: the terminal device receives first higher-layer signaling or first physical-layer signaling sent by the network device; determines at least one flexible symbol as a sensing symbol based on the parameters of the first higher-layer signaling, or determines at least one flexible symbol as a sensing symbol based on the indication of the first physical-layer signaling.
[0078] In this embodiment, the terminal device can determine at least one flexible symbol as a sensing symbol through the parameters of the first higher layer signaling (specifically, RRC parameters, semi-static configuration method); optionally, if the terminal device fails to determine the sensing resource through the parameters of the first higher layer signaling, it can determine at least one flexible symbol as a sensing symbol through the dynamic indication of the first physical layer signaling, which can also be called dynamic configuration method.
[0079] In some optional embodiments of the present invention, the priorities of cell-specific RRC signaling, SFI, the first higher-layer signaling, and the first physical layer signaling gradually decrease; or,
[0080] The priorities of cell-specific RRC signaling or SFI, the first higher-layer signaling, and the first physical layer signaling gradually decrease; or,
[0081] The priority of cell-specific RRC signaling or SFI is higher than the priority of the first higher-layer signaling or the first physical layer signaling;
[0082] The cell-specific RRC signaling and the SFI are used to configure the symbols in the frame structure as communication symbols.
[0083] In relevant technical solutions, the configuration methods for transmission resources include semi-static configuration via RRC signaling and dynamic configuration via physical layer signaling (such as DCI). RRC signaling includes cell-wide semi-static configuration and cell-specific semi-static configuration. The transmission mode of uplink and downlink symbols configured via cell-wide semi-static RRC signaling cannot be changed by other signaling. If cell-wide semi-static RRC signaling configures a symbol for flexible transmission, it can be dynamically configured as an uplink or downlink transmission symbol via cell-specific RRC signaling semi-static configuration or DCI. If a symbol is always configured as a flexible symbol, it is a reserved symbol, used neither for uplink nor downlink transmission.
[0084] In this embodiment, if the first higher-layer signaling or the first physical-layer signaling conflicts with the cell-specific RRC signaling used for semi-static configuration of communication symbols (such as uplink symbols and downlink symbols) and the SFI used for dynamic configuration of communication symbols, the priority of the cell-specific RRC signaling, the priority of the SFI, the priority of the first higher-layer signaling, and the priority order among the first physical-layer signaling satisfy any of the above priority orderings.
[0085] For example, the cell-specific RRC signaling in this embodiment may specifically be TDD-UL-DL-ConfigDedicated.
[0086] In some optional embodiments of the present invention, when the communication device is a terminal device, determining the sensing direction of at least one sensing symbol includes: the terminal device receiving second configuration information sent by the network device, and determining the sensing direction of at least one sensing symbol based on the second configuration information.
[0087] In this embodiment, in order to determine whether the sensing direction of the sensing symbol is uplink or downlink, the network device configures the sensing direction of the sensing symbol through signaling, that is, sends second configuration information through signaling.
[0088] In some optional embodiments, the terminal device receives second configuration information sent by the network device, and determines the sensing direction of at least one sensing symbol based on the second configuration information, including: the terminal device receives second higher-layer signaling or second physical-layer signaling sent by the network device; determines the sensing direction of at least one sensing symbol based on the parameters of the second higher-layer signaling, or determines the sensing direction of at least one sensing symbol based on the indication of the second physical-layer signaling.
[0089] In this embodiment, the terminal device can determine the sensing direction of at least one sensing symbol through the parameters of the second higher layer signaling (specifically, RRC parameters, semi-static configuration method); optionally, if the terminal device fails to determine the sensing direction of at least one sensing symbol through the parameters of the second higher layer signaling, it can determine the sensing direction of at least one sensing symbol through the indication of the second physical layer signaling, which can also be called dynamic configuration method.
[0090] For example, the second higher-layer signaling may be RRC signaling, and the second physical layer signaling may be DCI.
[0091] In some optional embodiments of the present invention, the system parameters of the sensing symbols are the same as the system parameters of the communication symbols in the frame structure, and the system parameters include at least one of the following parameters: subcarrier spacing and number of symbols in a time slot.
[0092] In this embodiment, the system parameters for sensing symbols are the same as those for transmitting data symbols. These system parameters include subcarrier spacing, the number of symbols in a time slot, and other parameters.
[0093] In some optional embodiments, the method may further include: the terminal device receiving third configuration information sent by the network device, the third configuration information including at least one of the following: transmission direction of communication symbols, time slot configuration period, number of uplink and downlink time slots, number of uplink and downlink symbols, number of uplink and downlink sensing symbols, etc.
[0094] In some alternative embodiments, the method further includes: the communication device sending a first signal, the first signal being used for sensing functions; the communication device receiving a first response signal corresponding to the first signal, the first response signal being a signal after the first signal is reflected or scattered by a target object; the communication device obtaining sensing information based on the first response signal; the first signal being sent through a sensing symbol; and the first response signal being received through a sensing symbol.
[0095] This embodiment presents a technical solution for active sensing by a communication device. During active sensing, the communication device, acting as the active sensing party, sends signals for sensing functions, specifically a first signal for sensing functions via sensing symbols. For example, when the communication device is a terminal device, it can generate a sensing signal sequence (i.e., the first signal) according to the sensing signal configuration parameters configured by the network device, and send this first signal via sensing symbols used for uplink transmission. When the communication device is a network device, it can generate a sensing signal sequence (i.e., the first signal) according to specified (or agreed upon, defined) sensing signal configuration parameters, and send this first signal via sensing symbols used for uplink transmission. After the first signal is emitted, it is reflected or scattered by target objects in the environment and received by the communication device via sensing symbols used for downlink transmission as a first response signal.
[0096] For example, the terminal device sends the first signal through a sensing symbol used for uplink transmission, and the terminal device receives the first response signal through a sensing symbol used for downlink transmission, and / or the network device or other terminal device receives the first response signal through a sensing symbol used for downlink transmission, thereby obtaining sensing information (such as speed information, distance information, etc.).
[0097] In some alternative embodiments, the method further includes: the communication device receiving a second signal via the sensing symbol, the second signal being a sensing signal reflected or scattered by a target object, or a sensing signal emitted by other communication devices, the sensing signal being a signal used for sensing functions; and the communication device obtaining sensing information based on the second signal.
[0098] This embodiment is a technical solution for passive sensing in communication devices. In the passive sensing process, the communication devices (terminal devices and / or network devices) do not need to send signals for sensing functions, but instead receive a second signal in the sensing symbol used for downlink transmission. The second signal can be a sensing signal reflected or scattered by the target object, or a sensing signal emitted by other communication devices, etc.
[0099] Based on the foregoing embodiments, this invention also provides a frame structure configuration method. Figure 2 This is a flowchart illustrating the frame structure configuration method according to an embodiment of the present invention. Figure 2 ;like Figure 2 As shown, the method includes:
[0100] Step 201: The network device sends first configuration information and second configuration information to the terminal device. The first configuration information is used by the terminal device to determine that at least one flexible symbol in the frame structure is a sensing symbol. The second configuration information is used by the terminal device to determine the sensing direction of at least one sensing symbol. The sensing symbol is used to sense target objects or environmental information.
[0101] This embodiment mainly addresses the solution of configuring sensing resources for the network device when the communication device in the aforementioned embodiments is a terminal device.
[0102] In some optional embodiments of the present invention, before the network device sends the first configuration information to the terminal device, the method further includes: the network device receiving the sensing capability reporting result of the terminal device;
[0103] The network device sends first configuration information to the terminal device, including: when the network device determines that the terminal device has sensing capabilities based on the sensing capability reporting result, configuring sensing resources for the terminal device and sending the first configuration information to the terminal device.
[0104] In this embodiment, when the terminal device performs sensing, the network device needs to configure sensing resources for it. If the terminal device has sensing capabilities, it sends a sensing capability reporting result to the network device. Based on the terminal device's sensing capability reporting result, the network device determines that the terminal device has sensing capabilities and then sends first configuration information to the terminal device.
[0105] In some optional embodiments of the present invention, the network device sends first configuration information to the terminal device, including: the network device sending first higher-layer signaling or first physical layer signaling to the terminal device; the parameters of the first higher-layer signaling are used by the terminal device to determine at least one flexible symbol as a sensing symbol, and the first physical layer signaling is used to indicate that at least one flexible symbol is a sensing symbol.
[0106] In this embodiment, to ensure that the sensing function does not interfere with or preempt normal communication resources, the network device configures flexible symbols not used for data transmission as sensing symbols through signaling configuration, that is, sends first configuration information to the terminal device through signaling. The signaling can be first higher-layer signaling or first physical-layer signaling; for example, the first higher-layer signaling can be RRC signaling, and the first physical-layer signaling can be DCI.
[0107] In some optional embodiments of the present invention, the priorities of cell-specific RRC signaling, SFI, the first higher-layer signaling, and the first physical layer signaling gradually decrease; or,
[0108] The priorities of cell-specific RRC signaling or SFI, the first higher-layer signaling, and the first physical layer signaling gradually decrease; or,
[0109] The priority of cell-specific RRC signaling or SFI is higher than the priority of the first higher-layer signaling or the first physical layer signaling;
[0110] The cell-specific RRC signaling and the SFI are used to configure the symbols in the frame structure as communication symbols.
[0111] In this embodiment, if the first higher-layer signaling or the first physical-layer signaling conflicts with the cell-specific RRC signaling used for semi-static configuration of communication symbols (such as uplink symbols and downlink symbols) and the SFI used for dynamic configuration of communication symbols, the priority of the cell-specific RRC signaling, the priority of the SFI, the priority of the first higher-layer signaling, and the priority order among the first physical-layer signaling satisfy any of the above priority orderings.
[0112] For example, the cell-specific RRC signaling in this embodiment may specifically be TDD-UL-DL-ConfigDedicated.
[0113] In some optional embodiments of the present invention, the network device sends second configuration information to the terminal device, including: the network device sending second higher-layer signaling or second physical-layer signaling to the terminal device, wherein the parameters of the second higher-layer signaling are used by the terminal device to determine the sensing direction of at least one sensing symbol, and the second physical-layer signaling is used to instruct the terminal device to determine the sensing direction of at least one sensing symbol.
[0114] In this embodiment, to determine whether the sensing direction of the sensing symbol is uplink or downlink, the network device configures the sensing direction of the sensing symbol through signaling, that is, sends second configuration information through signaling. For example, the second higher-layer signaling can be RRC signaling, and the second physical layer signaling can be DCI.
[0115] In this embodiment, the terminal device can determine the sensing direction of at least one sensing symbol through the parameters of the second higher layer signaling (specifically, RRC parameters, semi-static configuration method); optionally, if the terminal device fails to determine the sensing direction of at least one sensing symbol through the parameters of the second higher layer signaling, it can determine the sensing direction of at least one sensing symbol through the indication of the second physical layer signaling, which can also be called dynamic configuration method.
[0116] This invention, through the addition of a new symbol, the sensing symbol, enables the sensing function to be implemented on the existing frame structure without changing the existing frame structure configuration. This is achieved by configuring a flexible symbol as the sensing symbol, that is, reusing the flexible symbol in the frame structure as the sensing symbol. In addition, by specifying the signaling priority of the frame structure configuration, it is possible to ensure that the sensing function does not interfere with or preempt normal communication resources, thus realizing the flexible and dynamic configuration of the sensing and communication functions on demand.
[0117] The frame structure configuration method of this invention will be described below with specific examples.
[0118] Example 1
[0119] In this example, the transmission direction of each symbol in the frame structure is configured through the higher-layer signaling RRC parameter (TDD-UL-DL-ConfigCommon), such as... Figure 3a As shown, the first three symbols of the 14 symbols are downlink signals D, the last symbol is uplink signal U, and the remaining 10 symbols are flexible symbols F. Since neither the cell-specific RRC signaling (TDD-UL-DL-ConfigDedicated) nor the DCI (SFI) reconfigures the transmission direction of these 10 flexible symbols F, these symbols are not used for uplink or downlink transmission, i.e., they are reserved symbols, which can be selected and multiplexed as sensing symbols S through configuration.
[0120] In this example, six of the ten flexible symbols F are multiplexed into a sensing symbol S via the first physical layer signaling (i.e., DCI), such as... Figure 3b The perception symbol S with a background is shown in the image. Furthermore, the perception direction of the perception symbol S is indicated by the second physical layer signaling (i.e., DCI), as shown... Figure 3c As shown, three of the six sensing symbols S are configured as downlink sensing signals S. D Three sensing symbols are configured as uplink sensing signals S U .
[0121] Example 2
[0122] This example includes the following steps:
[0123] Step 1: Configure the transmission direction of each symbol in the frame structure using the higher-layer signaling RRC parameters (TDD-UL-DL-ConfigCommon), such as... Figure 4a As shown, the first three symbols of the 14 symbols are downlink signals D, the last symbol is uplink signal U, and the remaining 10 symbols are flexible symbols F.
