Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a frame structure configuration method, a frame structure configuration device, a communication device, a chip, a computer-readable storage medium, and a computer program product. Background Art
[0002] In a cooperative telepathy system, the sensing signal sent by base station A takes a certain amount of time to reach base station B. However, the base station needs to consider the frame structure of normal communicating users and cannot send the signal in advance. Therefore, the sensing signal received by base station B will exceed the current symbol time. Considering that the sensing signal will interfere with the next symbol, the sensing signal is usually sent before the global priority (GP). Furthermore, due to the weak sensing echo signal strength, to avoid interference with normal uplink users, uplink users are usually not scheduled in the current symbol. This results in a waste of communication resources and is a resource overhead problem that cooperative telepathy has always faced. Summary of the Invention

[0035] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0036] It should be noted that in the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the embodiments of the present application, the character " / " generally indicates that the associated objects are in an "or" relationship.
[0037] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.
[0038] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
[0039] An integrated communication and perception system refers to a system that has both communication and perception capabilities through integrated design (spectrum resource sharing, integrated air interface, integrated hardware architecture, etc.), multi-point collaboration, and intelligent information interaction. Its working modes are divided into two categories: independent perception and collaborative perception.
[0040] Independent Perception: Reference Figure 1 , Figure 1This is a schematic diagram of the independent sensing mode provided in an embodiment of the present application. Node A transmits a sensing signal and receives reflected echo signals from targets 1, 2, and 3. This information determines the characteristic parameters of the surrounding environment and enables sensing functions such as target detection, positioning, identification, and tracking. The advantage is that it can complete the sensing process for off-network targets without the assistance of other on-network nodes. The main challenges lie in the low energy of the echo signals and the presence of self-interference.
[0041] Collaborative Awareness Pattern: Reference Figure 2 , Figure 2 Schematic diagram of the collaborative sensing mode provided in the embodiment of this application Figure 1 Node A transmits a sensing signal, and node B receives the reflected signals from targets 1 and 2. After information exchange and fusion between the nodes, the environmental characteristic parameters between the transmitting and receiving nodes are obtained. This approach offers advantages in terms of eliminating self-interference between transmission and reception, and achieving collaborative reception processing gain through multi-node collaboration. The main challenge lies in inter-node synchronization.
[0042] Relying on the large-scale deployment of mobile communication networks to build a collaborative synaesthesia network, it has the advantages of collaborative reception and fusion processing gain, no need for self-interference deletion, no need for hardware modification, and low-cost and rapid technology implementation.
[0043] refer to Figure 3 , Figure 3 Schematic diagram of the collaborative sensing mode provided in the embodiment of the present application Figure 2 , Figure 3 Base station A transmits a sensing signal, and base station B receives the echo signal reflected by detection target 1 in a collaborative sensing mode. In addition, base station A communicates with communication user 1 within its range, and base station B communicates with communication users 2, 3, and 4 within its range. Since the inter-station distance (ISD) is generally less than 1000m and the propagation delay is less than 3.3us, and the shortest OFDM symbol in NR is 4.46us, the transmission and reception of the sensing signal will be within the same symbol, so the uplink and downlink configurations of the transmitting and receiving base stations need to be changed. Figure 4 As shown, Figure 4 Schematic diagram of collaborative sensing resource configuration provided in the embodiment of this application Figure 1 , sending node A is in Downlink symbol S D When the receiving node B is in Uplink symbol S U .
[0044] refer to Figure 5 , Figure 5This is a schematic diagram of the time division duplexing (TDD) frame structure configuration provided in an embodiment of the present application. In a TDD system, signal reception and transmission are distinguished by time. Due to propagation delay, there is a time difference T between the user's reception start time and the base station's transmission start time. In addition, considering the propagation delay of the user's transmitted signal, a guard period (GP) is added in the middle of the downlink to uplink switching in the frame structure. The guard interval is greater than twice the propagation delay, and data transmission is not defined within the guard interval.
[0045] For the cooperative interawareness system, the perception signal sent by base station A reaches base station B after a certain propagation time. However, the base station side needs to consider the frame structure of the normal communication user and cannot send the signal in advance. Therefore, the perception signal received by base station B will exceed the current symbol time, such as Figure 4 As shown in the figure, to avoid interference from the sensing signal on the next symbol, the sensing signal is typically sent before the GP. Furthermore, because the sensing echo signal strength is relatively weak, uplink users are typically not scheduled in the current symbol to avoid interference from normal uplink users. This results in a waste of communication resources, a persistent resource overhead challenge for collaborative telepathy.
[0046] Figure 6 Schematic diagram of the implementation process of the frame structure configuration method provided in the embodiment of the present application Figure 1 ,like Figure 6 As shown, an embodiment of the present application provides a frame structure configuration method, the method comprising the following steps:
[0047] Step 601: The first network device obtains a first frame structure configuration and a second frame structure configuration; the first frame structure configuration is used to configure a first frame structure, and the first frame structure is used by the first network device to receive a perception signal sent by the second network device; the second frame structure configuration is used to configure a second frame structure, and the second frame structure is used by the first network device to receive a communication signal sent by a terminal device.
[0048] Here, the first network device obtains two sets of frame structure configurations, namely the first frame structure configuration and the second frame structure configuration, and distinguishes the frame structures of the received perception signal and the communication signal to avoid resource conflicts.
[0049] It should be noted that the first frame structure and the second frame structure in the embodiment of the present application may be part of a complete frame structure, and a complete frame structure may include multiple first frame structures or multiple second frame structures.
[0050] Exemplarily, the communication signal sent by the terminal device may be an uplink communication signal.
[0051] In an optional embodiment of the present application, the first frame structure includes M1 uplink sensing symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0052] Among them, the positions of the M1 uplink perception symbols correspond to the positions of the M1 downlink perception symbols in the third frame structure; the M1 uplink perception symbols are used by the first network device to receive perception signals; and the third frame structure is used by the second network device to send perception signals to the first network device.
[0053] Here, the third frame structure is the frame structure of the sending node (the second network device), and the first frame structure is the frame structure of the receiving node (the first network device) for the perception service. In the collaborative perception communication mode, the receiving node needs to receive the perception signal at the position of the uplink perception symbol. Therefore, the position of the uplink perception symbol of the receiving node corresponds to the position of the downlink perception symbol of the frame structure of the sending node, ensuring that the receiving node successfully receives the downlink perception signal sent by the sending node.
[0054] In an embodiment of the present application, the sending node and the receiving node can negotiate to send a perception signal before the GP symbol, so that the time beyond the current symbol is within the GP and will not cause inter-symbol interference to subsequent communication symbols.
[0055] In an optional embodiment of the present application, the second frame structure includes K GP symbols and L uplink symbols; K and L are positive integers;
[0056] Among them, the K GP symbols include M1 GP symbols and (M2-N) GP symbols, and the positions of the M1 GP symbols correspond to the positions of the M1 uplink perception symbols; the L uplink symbols include N uplink symbols and M3 uplink symbols, and the value of N is determined based on the value of M1 and the value of M2; the L uplink symbols are used by the terminal device to send communication signals to the first network device.
[0057] Here, the second frame structure is a frame structure for communication services. In the collaborative perception communication mode, the receiving node must receive both perception signals and communication signals. The positions of the M1 GP symbols in the second frame structure correspond to the positions of the M1 uplink perception symbols in the first frame structure. When the receiving node receives the perception signal, it does not schedule related signals of the communication service to avoid interference between the communication service and the perception service, thereby ensuring the reliability of the perception service.
[0058] refer to Figure 7 , Figure 7 Schematic diagram of collaborative sensing resource configuration provided in the embodiment of this application Figure 2Here, M1 GP symbols are newly added GP symbols relative to the frame structure in the traditional communication mode (corresponding to Figure 7 The first modification in the , N uplink symbols are newly added uplink symbols relative to the frame structure of the traditional communication mode (corresponding to Figure 7 In the second frame structure, the newly added M2 GP symbols can meet the GP requirements of the communication service, because the length of the GP symbol is not reduced for the terminal device, and the newly added uplink symbols can increase uplink resources and improve uplink capabilities.
[0059] In an optional implementation manner of the present application, the value of N is determined based on the value of M2 and the value of M3, including:
[0060] If the value of M2 is less than the value of M3, then the value of N is less than or equal to the value of M2;
[0061] If the value of M2 is greater than or equal to the value of M3, the value of N is less than or equal to the value of M3-1.
[0062] In the embodiment of the present application, the value of N is determined based on the value of M1 and the value of M2. For example, when M1 < M2, the first N GP symbols corresponding to the uplink symbols of the first frame structure in the second frame structure are configured as uplink symbols; when M1 ≥ M2, the first (M2-1) GP symbols corresponding to the uplink symbols of the first frame structure in the second frame structure are configured as uplink symbols. For example, Figure 7 As shown, in the collaborative perception mode, the perception frame structure of the receiving node B is Su GP GP GP UUU, and the communication frame structure of the receiving node B is GP GP GP UUUU, that is, M1=1, M2=3, M3=3, N=1, K=M1+(M2-N)=3, L=N+M3=4.
[0063] In an optional embodiment of the present application, the third frame structure includes M1 downlink sensing symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0064] The positions of the M1 downlink perception symbols correspond to the positions of the M1 uplink perception symbols in the first frame structure; and the M1 downlink perception symbols are used by the second network device to send a perception signal.
[0065] In an embodiment of the present application, the receiving node maintains two communication frame structures, one is the communication frame structure under the traditional communication mode, and the other is the communication frame structure under the collaborative perception mode (i.e., the second frame structure). Normally, the communication frame structure under the traditional mode is used to communicate with the terminal device. When the perception function is activated, the communication frame structure under the collaborative perception mode is used to communicate with the terminal device.
[0066] Based on this, in an optional implementation manner of the present application, the method further includes:
[0067] The first network device sends a first signaling to the terminal device, where the first signaling is used to instruct the terminal device to switch from the first communication mode to the second communication mode or from the second communication mode to the first communication mode;
[0068] The frame structure corresponding to the first communication mode is the fourth frame structure, and the frame structure corresponding to the second communication mode is the second frame structure.
[0069] Here, the first communication mode is a traditional communication mode, and the second communication mode is a collaborative sensing mode.
[0070] In an optional embodiment of the present application, the fourth frame structure includes M1 downlink symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0071] Among them, the M4 uplink symbols are used by the terminal device to send communication signals to the first network device.
[0072] In an embodiment of the present application, the sending node and the receiving node can negotiate the perception frame structure. For example, the receiving node obtains the first frame structure configuration and sends the first frame structure configuration to the sending node for the sending node to determine the third frame structure. The sending node can also obtain the third frame structure configuration and send the third frame structure configuration to the receiving node for the sending node to determine the first frame structure. The third frame structure is used for the sending node to send a perception signal.
[0073] Based on this, in an optional implementation manner of the present application, the method further includes:
[0074] The first network device sends the first frame structure configuration to the second network device; the first frame structure configuration is used by the second network device to determine a third frame structure configuration; or,
[0075] The first network device receives a third frame structure configuration sent by the second network device, and determines the first frame structure configuration based on the third frame structure configuration;
[0076] The third frame structure is configured to configure a third frame structure, and the third frame structure is used by the second network device to send a perception signal.
[0077] Figure 8 Schematic diagram of the implementation process of the frame structure configuration method provided in the embodiment of the present application Figure 2 ,like Figure 8 As shown, an embodiment of the present application provides a frame structure configuration method, the method comprising the following steps:
[0078] Step 801: The terminal device receives a first signaling sent by a first network device, where the first signaling is used to instruct the terminal device to switch from a first communication mode to a second communication mode or from a second communication mode to the first communication mode; wherein the frame structure corresponding to the first communication mode is a fourth frame structure, and the fourth frame structure is used by the terminal device to send a communication signal to the first network device in the first communication mode; and the frame structure corresponding to the second communication mode is a second frame structure, and the second frame structure is used by the terminal device to send a communication signal to the first network device in the second communication mode.
[0079] In an embodiment of the present application, the first network device maintains two communication frame structures, one is the communication frame structure under the traditional communication mode, and the other is the communication frame structure under the collaborative perception mode (i.e., the second frame structure). Normally, the communication frame structure under the traditional mode is used to communicate with the terminal device. When the perception function is activated, the communication frame structure under the collaborative perception mode is used to communicate with the terminal device.
[0080] In an optional embodiment of the present application, the fourth frame structure includes M1 downlink symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0081] Among them, the M3 uplink symbols are used by the terminal device to send communication signals to the first network device.
[0082] The fourth frame structure is a communication frame structure under the traditional communication mode.
[0083] In an optional embodiment of the present application, the second frame structure includes K GP symbols and L uplink symbols; K and L are positive integers;
[0084] Among them, the K GP symbols include M1 GP symbols and (M2-N) GP symbols, and the positions of the M1 GP symbols correspond to the positions of the M1 uplink perception symbols in the first frame structure; the L uplink symbols include N uplink symbols and M3 uplink symbols, and the value of N is determined based on the value of M1 and the value of M2; the L uplink symbols are used by the terminal device to send communication signals to the first network device.
[0085] Here, the second frame structure is the frame structure for communication services in the collaborative perception mode. In the collaborative perception communication mode, the receiving node must receive both perception signals and communication signals. The positions of the M1 GP symbols in the second frame structure correspond to the positions of the M1 uplink perception symbols in the first frame structure. When the receiving node receives the perception signal, it does not schedule related signals of the communication service to avoid interference between the communication service and the perception service, thereby ensuring the reliability of the perception service.
[0086] Here, the M1 GP symbols are newly added GP symbols relative to the frame structure in the traditional communication mode, and the N uplink symbols are newly added uplink symbols relative to the frame structure in the traditional communication mode. In the second frame structure, the newly added M1 GP symbols can meet the GP requirements of the communication service, because, for the terminal equipment, the length of the GP symbol has not been reduced, and the newly added uplink symbols can increase uplink resources and improve uplink capabilities.
[0087] In the embodiment of the present application, the value of N is determined based on the value of M1 and the value of M2. For example, when M1 < M2, the first N GP symbols corresponding to the uplink symbols of the first frame structure in the second frame structure are configured as uplink symbols; when M1 ≥ M2, the first (M2-1) GP symbols corresponding to the uplink symbols of the first frame structure in the second frame structure are configured as uplink symbols. For example, refer to Figure 7 , Figure 7 Schematic diagram of the frame structure configuration provided in the embodiment of this application Figure 2 ,like Figure 7 As shown, in the collaborative perception mode, the perception frame structure of the receiving node B is Su GP GP GP UUU, and the communication frame structure of the receiving node B is GP GP GP UUUU, that is, M1=1, M2=3, M3=3, N=1, K=M1+(M2-N)=3, L=N+M3=4.
[0088] In an optional embodiment of the present application, the first frame structure includes M1 uplink sensing symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0089] Among them, the positions of the M1 uplink perception symbols correspond to the positions of the M1 downlink perception symbols in the third frame structure; the M1 uplink perception symbols are used by the first network device to receive perception signals; and the third frame structure is used by the second network device to send perception signals to the first network device.
[0090] The first frame structure is the frame structure of the receiving node for the perception service. In the collaborative perception communication mode, the receiving node needs to receive the perception signal at the position of the uplink perception symbol. Therefore, the position of the uplink perception symbol of the receiving node corresponds to the position of the downlink perception symbol of the frame structure of the sending node, ensuring that the receiving node successfully receives the downlink perception signal sent by the sending node.
[0091] In an optional embodiment of the present application, the third frame structure includes M1 downlink sensing symbols, M2 GP symbols, and M3 uplink symbols; M1, M2, and M3 are all positive integers;
[0092] The positions of the M1 downlink perception symbols correspond to the positions of the M1 uplink perception symbols in the first frame structure; and the M1 downlink perception symbols are used by the second network device to send a perception signal.
[0093] Here, the third frame structure is a frame structure for the sending node to send the perception signal.
[0094] In order to further understand the technical solution of this application, the following is an explanation with reference to specific examples.
[0095] Example 1
[0096] refer to Figure 9 , Figure 9 This is a schematic diagram of the frame structure in the traditional communication mode provided by the embodiment of the present application. Figure 9 As shown, base station 1 and base station 2 have consistent uplink and downlink configurations, the symbol boundaries on the base station side are aligned, UE1 is within the range of base station 1, UE2 is within the range of base station 2, and the symbol boundary on the user side is related to the distance from the user to the base station.
[0097] Example 2
[0098] refer to Figure 10 , Figure 10 Schematic diagram of the frame structure in the collaborative sensing mode provided in the embodiment of the present application Figure 1 ,like Figure 10 As shown, the receiving node B maintains two sets of frame structures, namely the frame structure of the perception service and the frame structure of the communication service. In this example, the perception signal occupies an uplink symbol Su in the perception frame structure. There are three GP symbols in the perception frame structure. The symbol corresponding to Su in the communication frame structure is modified to GP (corresponding to Figure 10 ① in the , and change the last GP symbol to the uplink symbol U (corresponding to Figure 10 ②) in the figure increases uplink resources for the terminal device.
[0099] Example 3

In this example, the sensing signal occupies three uplink symbols Su in the sensing frame structure. There are three GP symbols in the sensing frame structure. The three symbols corresponding to Su in the communication frame structure are modified to GP (corresponding to Figure 11 ① in the , and change the last two GP symbols to uplink symbols U (corresponding to Figure 11 ②) in the figure increases uplink resources for the terminal device.
[0101] The frame structure configuration method provided in the embodiment of the present application is that the receiving node maintains two sets of frame structure configurations in the collaborative perception mode, namely the perception frame structure and the communication frame structure, and notifies the terminal to use the communication frame structure in the collaborative perception mode for communication when the perception signal is periodically configured. When the perception signal is non-periodically configured, the terminal side changes the frame structure configuration according to the notification from the base station side and uses the frame structure in the traditional communication mode for communication. This solves the above-mentioned problems such as inter-symbol interference and uplink user interference. By maintaining two sets of frame structure constraints and configurations for communication and perception respectively on the base station side, resource conflicts and interference are avoided, and resource utilization is improved.
[0102] The embodiment of the present application also provides a frame structure configuration device 1200, referring to Figure 12 The frame structure configuration apparatus 1200 in this embodiment is applied to a first network device and includes:

[0104] In an embodiment of the present application, the first frame structure includes M1 uplink perception symbols, M2 GP symbols and M3 uplink symbols; M1, M2 and M3 are all positive integers; wherein the position of the M1 uplink perception symbol corresponds to the position of the M1 downlink perception symbol in the third frame structure; the M1 uplink perception symbol is used by the first network device to receive a perception signal; and the third frame structure is used by the second network device to send a perception signal to the first network device.
