[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority to Chinese Patent Application No. 202410904302.5, filed on July 5, 2024 in China, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of wireless communication, and particularly relates to a frame structure configuration method, apparatus, storage medium, program product and communication device. BACKGROUND

Relying on the scale deployment of mobile communication networks to build a cooperative sensing network has the advantages of cooperative reception and fusion processing gain, no need for self-interference cancellation, no need for hardware modification, low cost and rapid technology landing. In the cooperative sensing mode, node A transmits a sensing signal, which is reflected by a target, and node B receives the echo signal and performs target sensing. However, in actual networking, the cooperative sensing mode of A transmitting and B receiving needs to change the uplink and downlink configuration of the transmitting and receiving nodes, which breaks the traditional uplink and downlink configuration mode.

[0005] In the frame structure scheme of the related art, the downlink time slots of some nodes are modified to uplink time slots, that is, the surrounding communication nodes are in the downlink time slots and transmit communication signals / sensing signals, and the sensing nodes are in the uplink time slots and receive echo signals and perform target sensing. However, in the case where most nodes are in the downlink time slots, the nodes in the uplink time slots will be subjected to complex interference from adjacent nodes. Therefore, how to configure the uplink and downlink time slots of the cooperative nodes in the cooperative sensing mode to reduce interference and achieve accurate target sensing is a problem to be solved.

[0038] Before describing the frame structure configuration scheme of the present disclosure in detail, a cooperative sensing in the related art is first described briefly.

[0039] FIG. 1 is a diagram illustrating a cooperative sensing mode according to the related art. As shown in FIG. 1, a node A transmits a sensing signal, a target (e.g., target 1 or target 2 in FIG. 1) reflects the sensing signal, and a node B receives a return signal and performs target sensing.

[0040] In actual networking, the cooperative sensing mode in which the node A transmits a sensing signal and the node B receives a return signal reflected by a target requires changing uplink and downlink configurations of the transmitting and receiving nodes, and breaking a conventional uplink and downlink configuration mode. In the related art, downlink time slots of some nodes are modified to uplink time slots, i.e., surrounding communication nodes are in downlink time slots and transmit communication signals or sensing signals, and nodes performing sensing (hereinafter referred to as sensing nodes) are in uplink time slots and receive return signals and perform target sensing. By constructing a unified uplink and downlink time slot in a whole network, a cooperative sensing network is constructed, and a communication and sensing integrated function is achieved. FIG. 2 is a diagram illustrating a configuration relationship between uplink and downlink time slots of nodes according to the related art. In FIG. 2, a grid area represents nodes configured with uplink time slots, and a dot area represents nodes configured with downlink time slots. As shown in FIG. 2, in a case where most nodes are in downlink time slots (dots), nodes in uplink time slots (grid) are interfered by adjacent nodes. Therefore, a frame structure of cooperative nodes in a cooperative sensing scenario needs to be considered to reduce interference of adjacent nodes and to exert an advantage of cooperative sensing.

[0041] In the related art, a frame structure can be configured by cell uplink and downlink configuration and terminal uplink and downlink configuration to achieve semi-static uplink and downlink configuration. FIG. 3 is a schematic diagram of a frame structure of a 5 millisecond (ms) period in the related art. As shown in FIG. 3, three downlink time slots (D), three uplink time slots (U), and eight downlink symbols in a time slot after the full downlink time slot and six uplink symbols before the full uplink time slot can be configured by cell uplink and downlink configuration. For the middle flexible resource (F), terminal-specific uplink and downlink configuration can be performed.

[0042] In the related art, in an uplink and downlink time slot configuration scheme in an inter-station (inter-base station) cooperative sensing mode, a few downlink time slots of a node can be changed to uplink time slots in a flexible time slot position to receive sensing signals. FIG. 4 is a schematic diagram of a frame structure configuration for cooperative sensing in the related art. As shown in FIG. 4, five downlink time slots, four uplink time slots, and one flexible time slot are configured in a period for other nodes (i.e., nodes for communication). In the flexible time slot, the first eight symbols are downlink symbols, the last three symbols are uplink symbols, and the middle three symbols are used as a guard interval between uplink and downlink. For a transmitting node for cooperative sensing, the last several downlink symbols in the flexible time slot can be modified as sensing downlink symbols to transmit sensing signals. For a receiving node for cooperative sensing, the last several downlink symbols in the flexible time slot can be modified as sensing uplink symbols to receive echo signals reflected by a target.

[0043] However, referring to FIG. 2, in a cooperative sensing network, a node transmitting a sensing signal and a node receiving an echo signal (e.g., node A and node B in FIG. 1) form a cooperative node cluster to perform cooperative sensing, and the cooperative node cluster has an impact on adjacent nodes. Since most nodes (e.g., other nodes for communication) are in downlink time slots / symbols, the receiving node in the cooperative node cluster will receive communication signals of adjacent nodes while receiving corresponding echo signals, resulting in a complex and serious interference problem for the receiving node and affecting sensing quality.

[0044] As can be seen, in the related art, sensing resources are configured in downlink symbol positions of downlink time slots or flexible time slots, which will be interfered by communication signals of adjacent nodes, seriously affecting sensing accuracy. Moreover, this configuration method of sensing resources can only achieve a state in which two nodes for cooperative sensing always transmit and receive, and cannot achieve alternating sensing between the two nodes, which has a small number of applicable modes and is not flexible in configuration. Therefore, how to configure uplink and downlink time slots of cooperative nodes in a cooperative sensing mode to reduce interference and achieve accurate sensing of a target is a problem to be solved.

[0045] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0046] In the description of the present disclosure, it should be noted that the terms "first", "second", "third", etc. are only for descriptive purposes and cannot be understood or implied to indicate or imply relative importance. These terms are only used to distinguish one element (or threshold, application, or instruction, or operation) from another element (or threshold, application, or instruction, or operation). For example, a first operation can be referred to as a second operation, and a second operation can also be referred to as a first operation without departing from the scope of the present disclosure, and the first operation and the second operation are both operations, but they are not the same operation.

[0047] The term "and / or" in the embodiments of the present disclosure means any and all possible combinations of one or more of the associated listed items. It should be noted that when used in the present specification, "comprise / comprising" specifies the presence of stated features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or groups thereof.

[0048] The steps in the embodiments of the present disclosure do not necessarily have to be processed in the order described, and the steps can be selectively rearranged, deleted, or added as needed. The step description in the embodiments of the present disclosure is only an optional order combination, and does not represent all order combinations of the embodiments of the present disclosure. The order of the steps in the embodiments cannot be considered as a limitation of the present disclosure.

[0049] The embodiments of the present disclosure provide a frame structure configuration method, which is applied to a network device. FIG. 5 is a flowchart of a frame structure configuration method according to an embodiment of the present disclosure. As shown in FIG. 5, the method comprises the following steps.

[0050] In step 101, configuration information corresponding to each node is sent, and the configuration information is used to configure one or more continuous uplink symbols and / or flexible symbols at the end of each pattern in one or more patterns in a first frame structure for sensing measurement; the first frame structure at least includes the one or more patterns.

[0051] In the embodiments of the present disclosure, perception (or perception measurement, perception function, etc.) refers to collecting direct, reflected, scattered signals of radio waves (or signals, perception signals, etc.), obtaining information such as attributes and states of target objects or environment information through detection or processing of the collected signals, and then completing positioning, ranging, speed measurement, detection, identification, etc. according to the perceived information. In actual application, the specific perception content can be related to the business application scenario.

[0052] In the embodiment, the network device is at least a network device capable of configuring a frame structure, which can be a server (such as a positioning server), a network function, an access network device, a core network device, etc., or can also be a network center node, a control node, a local control unit, etc. in a cooperative perception scenario. It can be understood that the present disclosure does not limit the implementation form of the network device, and any device capable of realizing the functions of the network device described in the embodiments of the present disclosure is within the protection scope of the present disclosure.

[0053] In the embodiment, the node (such as the first node or the second node) can be an access network device or a terminal device. The access network device can be, for example, a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a next-generation base station (gNB) in a new radio (NR) system, or it can also be a component or part of a device constituting a base station, etc. The terminal device can also be referred to as a terminal, which can be, for example, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. It can also be a handheld device, a vehicle-mounted device, etc. with wireless connection function, such as a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the node.

[0054] In the embodiment, the first frame structure comprises at least one frame structure in a configured period for sensing measurement, and the one or more patterns are patterns in which uplink symbols and / or flexible symbols configured for sensing measurement are located in all patterns included in the first frame structure. For example, if the first frame structure comprises only one pattern, the one or more patterns are the one pattern; or, if the first frame structure comprises a plurality of patterns, the one or more patterns are some or all of the patterns. It can be understood that, in the embodiment, the configuration information is used to configure one or more continuous uplink symbols and / or flexible symbols at the end of each pattern in at least some patterns in the first frame structure as symbols available for sensing measurement, so that a unified uplink and downlink time slot of each node in the sensing cooperation network can be constructed, sensing resources are configured in the uplink time slot or the flexible time slot, interference of communication signals of other nodes on sensing signals is reduced, normal communication of communication users and effective detection of sensing signals are ensured.

[0055] FIG. 6 is a schematic diagram of a comparison between a frame structure configuration scheme in the embodiment of the present disclosure and a frame structure configuration scheme in the related art in terms of uplink and downlink time slot relationship. As shown in part (a) of FIG. 6, in the related art, nodes for cooperation sensing form a cooperation node cluster, and the cooperation node cluster has an influence on adjacent nodes. Specifically, in the related art, by configuring downlink symbols of a receiving node as uplink symbols in a downlink time slot (or a flexible time slot), the sensing node receives an influence of communication signals of adjacent nodes while receiving sensing signals, and interference is prominent. In contrast, in the embodiment, one or more continuous uplink symbols and / or flexible symbols at the end of each pattern in one or more patterns in the first frame structure are configured for sensing measurement, so that uplink time slots of a transmitting node can be configured as downlink time slots in the uplink time slot. At this time, referring to part (b) of FIG. 6, adjacent nodes are in the uplink time slot, and have a smaller influence on the receiving node. At the same time, since the sensing signal energy is small, interference of the sensing signal on the uplink time slot of the adjacent node is reduced.

[0056] In some embodiments, the configuration information can be used to configure one or more continuous uplink symbols and / or flexible symbols at the end of each pattern in one or more patterns in the first frame structure for first direction transmission of the sensing signal, or can be used to configure one or more continuous uplink symbols and / or flexible symbols at the end of each pattern in one or more patterns in the first frame structure for second direction transmission of the sensing signal. For example, the configuration information can configure the one or more continuous uplink symbols and / or flexible symbols for sensing signal transmission (i.e., sensing downlink or sensing transmission) or for echo signal reception of the sensing signal (i.e., sensing uplink or sensing reception).

[0057] As an example, for a transmitting node for cooperative sensing, the network device can send corresponding configuration information to the transmitting node for configuring one or more continuous uplink symbols and / or flexible symbols at the end of each of one or more patterns in the first frame structure for transmitting the sensing signal, i.e., for sensing downlink; for a receiving node for cooperative sensing, the network device can send corresponding configuration information to the receiving node for configuring one or more continuous uplink symbols and / or flexible symbols at the end of each of one or more patterns in the first frame structure for receiving the echo signal of the sensing signal after reflection by the target, i.e., for sensing uplink.

[0058] Considering the uncertainty of the location of the sensing target, the target has different angular spreads for different nodes, and the nodes for cooperative sensing in this embodiment can all have receiving signal processing capability. As an example, for a first node, the network device can send corresponding configuration information to the first node for configuring one or more continuous uplink symbols and / or flexible symbols at the end of one of the one or more patterns in the first frame structure for first direction transmission of the sensing signal, and for configuring one or more continuous uplink symbols and / or flexible symbols at the end of another of the one or more patterns in the first frame structure for second direction transmission of the sensing signal; and for a second node, the network device can send corresponding configuration information to the second node for configuring one or more continuous uplink symbols and / or flexible symbols at the end of one of the one or more patterns in the first frame structure for second direction transmission of the sensing signal, and for configuring one or more continuous uplink symbols and / or flexible symbols at the end of another of the one or more patterns in the first frame structure for first direction transmission of the sensing signal. The first direction transmission can be, for example, downlink transmission, i.e., sensing signal transmission, and the second direction transmission can be, for example, uplink transmission, i.e., reception of the echo signal of the sensing signal after reflection by the target. It can be understood that for the same node, this embodiment can configure symbols for sensing transmission and sensing reception in different patterns, so that one or more continuous uplink symbols and / or flexible symbols at the end of one of the patterns can be used for the first node to transmit the sensing signal and the second node to receive the echo signal of the sensing signal after reflection by the target, and one or more continuous uplink symbols and / or flexible symbols at the end of another of the patterns can be used for the second node to transmit the sensing signal and the first node to receive the echo signal of the sensing signal after reflection by the target, to achieve alternating sensing between the two nodes for cooperative sensing.

[0059] In the related art, one slot period can contain one or two slot patterns. FIG. 7 is a schematic diagram of frame structure configuration for different slot periods according to an embodiment of the present disclosure. As shown in part (a) of FIG. 7, one slot period only includes pattern 1, which is used as a reference when adjacent nodes communicate. The end of pattern 1 is an uplink slot, in which the adjacent nodes can receive communication signals. For node A and node B that perform cooperative sensing, the L uplink symbols at the end of pattern 1 corresponding to node A can be configured to be used for downlink transmission of sensing signals (i.e., S D ), L is a positive integer, and the L uplink symbols at the end of pattern 1 corresponding to node B can be configured to be used for uplink transmission of sensing signals (i.e., S U ). Thus, within the L symbols, node A transmits sensing signals, and node B receives corresponding echo signals, thereby achieving cooperative sensing.

[0060] Similarly, as shown in part (b) of FIG. 7, one slot period includes two slot patterns, i.e., pattern 1 and pattern 2. Again, pattern 1 and pattern 2 are used as a reference when adjacent nodes communicate. The end of pattern 1 and the end of pattern 2 are both uplink slots, in which the adjacent nodes can receive communication signals. For node A and node B that perform cooperative sensing, one or more uplink symbols at the end of pattern 1 corresponding to node A can be configured to be used for downlink transmission of sensing signals, and one or more uplink symbols at the end of pattern 2 corresponding to node A can be configured to be used for uplink transmission of sensing signals. One or more uplink symbols at the end of pattern 1 corresponding to node B can be configured to be used for uplink transmission of sensing signals, and one or more uplink symbols at the end of pattern 2 corresponding to node B can be configured to be used for downlink transmission of sensing signals. Thus, within the one or more uplink symbols at the end of pattern 1, node A can transmit sensing signals, and node B receives corresponding echo signals. Within the one or more uplink symbols at the end of pattern 2, node B can transmit sensing signals, and node A receives corresponding echo signals, thereby achieving alternating sensing. It should be noted that the combination of downlink slots (D), uplink slots (U), and flexible slots (F) in pattern 1 and pattern 2, the number of slots, and the like in the various drawings of the present disclosure are only exemplary and do not limit the specific forms of pattern 1 and pattern 2 in practice.

[0061] In some embodiments, the one or more uplink symbols and / or flexible symbols can be symbols within the same slot or symbols within different slots.

[0062] The frame structure configuration method of the embodiments of the present disclosure can avoid the interference of the downlink communication signals of the adjacent nodes on the sensing signals in the cooperative sensing, and the sensing resource is configured in the last several symbols of the pattern, without increasing the guard interval between the downlink symbol and the uplink symbol, thereby avoiding the resource waste.

[0063] In some embodiments, the first node and the second node cooperatively perform the sensing measurement, and the network device can only send the configuration information corresponding to the first node to the first node, and the first node can send the configuration information corresponding to the second node or the configuration information of itself (i.e., the first node) to the second node after determining to cooperatively sense with the second node, so that the second node learns the frame structure configuration of itself.

[0064] In an optional embodiment of the present disclosure, the configuration information at least includes one or more of the following information: first information for indicating the number of each time slot pattern contained in the first frame structure; second information for indicating the index of each pattern in the one or more patterns, the index being used to determine the corresponding pattern in the first frame structure; and third information for indicating the time slot number and / or symbol number corresponding to the one or more continuous uplink symbols and / or flexible symbols located at the end of each pattern.

[0065] In the embodiment, the first frame structure can include all frame structures in a sensing task period, and the first information can be used to configure the period information of the sensing measurement, for example, how many patterns are there between two sensing tasks, if the first frame structure only contains N pattern 1, the sensing task period is N patterns, if the first frame structure contains N1 pattern 1 and N2 pattern 2, the sensing task period is N1+N2. The second information can be used to configure the index corresponding to each pattern in the one or more patterns where the sensing resource is located, for example, the first frame structure only contains N pattern 1, and the second information can indicate the index of each pattern in the N patterns, or the first frame structure contains N1 pattern 1 and N2 pattern 2, and the index of the corresponding pattern in the N1 pattern 1 or in the N2 pattern 2 is indicated. It can be understood that the configuration information can include the first information for indicating the sensing task period (the number of periods occupied by pattern 1 and / or the number of periods occupied by pattern 2), the second information for indicating the pattern number where the sensing symbol is located, and the third information for indicating the time slot and / or symbol number of the sensing resource duration, etc.

[0066] In some embodiments, the second information can also be used to indicate an index of each pattern for sensing uplink and / or an index of each pattern for sensing downlink. The third information can be used to indicate a number of slots and / or a number of symbols for sensing uplink and / or a number of slots and / or a number of symbols for sensing downlink.

[0067] As an example, the first frame structure can include N patterns, and the N patterns are all the same slot pattern, such as pattern 1 shown in (a) of FIG. 7. The configuration information can be used to indicate that L uplink symbols at the end of the i-th pattern in the first frame structure are used for sensing measurement. Correspondingly, the first information can indicate that the first frame structure contains N patterns of pattern 1, the second information can indicate the index of the i-th pattern, such as i, which can determine the pattern in the N patterns, and the third information can indicate the number of symbols used for sensing measurement, i.e., L. Alternatively, the configuration information can be used to indicate that L uplink symbols at the end of the i-th pattern in the first frame structure are used for sensing downlink, and M uplink symbols at the end of the j-th pattern in the first frame structure are used for sensing uplink. In this case, the one or more patterns are the i-th pattern and the j-th pattern. Correspondingly, the first information can indicate that the first frame structure contains N patterns of pattern 1, the second information can indicate the index of the i-th pattern and the index of the j-th pattern, and the third information can indicate the number of symbols used for sensing downlink as L and the number of symbols used for sensing uplink as M.

[0068] As another example, the first frame structure can include N patterns, and the N patterns adopt two slot patterns, such as pattern 1 and pattern 2 shown in (b) of FIG. 7, where N1 patterns are pattern 1, and N2 patterns are pattern 2, and N1+N2=N. The configuration information can be used to indicate that L uplink symbols at the end of the i-th pattern in the N1 patterns corresponding to pattern 1 in the first frame structure are used for sensing measurement, and M uplink symbols at the end of the j-th pattern in the N2 patterns corresponding to pattern 2 in the first frame structure are used for sensing measurement. Correspondingly, the first information can indicate that the first frame structure contains N1 patterns of pattern 1 and N2 patterns of pattern 2, the second information can indicate that the two patterns for sensing measurement are the i-th pattern in the N1 patterns of pattern 1 and the j-th pattern in the N2 patterns of pattern 2, and the third information can indicate the number of symbols used for sensing measurement at the end of the two patterns, i.e., L and M.

[0069] The frame structure configuration method of the embodiments of the present disclosure can flexibly configure a sensing service period through first information, support different pattern periods, and realize accurate measurement of a target speed; multiple sensing symbols can be configured within one pattern or sensing resources can be configured across time slots through second information and third information, sensing energy accumulation can be realized, and sensing accuracy can be improved, and meanwhile, since sensing resource configuration is performed on the pattern, the existing protocol is less affected.

[0070] In an optional embodiment of the present disclosure, the sending of the corresponding configuration information to each node comprises one of the following: sending the corresponding configuration information to each node in a first mode, the first mode representing periodic sending; sending the corresponding configuration information to each node in a second mode, the configuration information sent in the second mode being activated through first signaling; and sending the corresponding configuration information to each node in a third mode, the third mode representing aperiodic sending. In this embodiment, the configuration information can be sent in a periodic configuration, semi-persistent configuration, or aperiodic configuration mode, wherein the aperiodic mode (i.e., the third mode) can send configuration information when the network device has a sensing requirement, and the configuration information can take effect in the next time slot.

[0071] This embodiment can solve the interference problem of the frame structure scheme in the related art in the cooperative sensing mode, and can use the uplink symbols and / or flexible symbols of the nodes configured for cooperative sensing for sensing measurement through periodic, aperiodic, or semi-persistent configuration, thereby reducing complex interference and improving network quality and sensing accuracy.

[0072] In some embodiments, when the configuration information is sent in the first mode or the second mode, the configuration information can include the first information, the second information, and the third information. It can be understood that in the case of periodic configuration or semi-persistent configuration, the corresponding period information can be indicated by the first information. When the configuration information is sent in the third mode, the configuration information can only include the third information, that is, in the case of aperiodic configuration, the position of the sensing resource in the next time slot can be configured through the third information, and the sensing resource is one or more uplink symbols and / or flexible symbols at the end of the corresponding pattern. For example, referring to part (b) of FIG. 7, the corresponding configuration information is sent to node A in the third mode, and the configuration information can only include the third information, for example, to indicate the number of sensing downlink symbols L and the number of sensing uplink symbols M. Thus, in the pattern 1 of the sensing downlink of node A, the last uplink symbol of pattern 1 can be taken as the starting point, and L uplink symbols can be configured from right to left as sensing downlink symbols (S D), for node A to perform sensing uplink in pattern2, the last uplink OFDM symbol of pattern2 can be taken as the starting point, and M uplink symbols can be configured from right to left as sensing uplink symbols (S U ), wherein L and M can be dynamically updated according to sensing requirements.

[0105] The related description of step 201 in the embodiment can refer to the related description of step 101 in the foregoing embodiment, and details are not described herein for the sake of brevity.

[0114] In an optional embodiment of the present disclosure, the first frame structure adopts two time slot patterns, and the first frame structure comprises at least a plurality of patterns; the receiving of the configuration information corresponding to the first node sent by the network device or the second node can comprise: receiving the fifth configuration information corresponding to the first node sent by the network device or the second node, the fifth configuration information being used for configuring the fourth number of continuous uplink symbols and / or flexible symbols at the end of the fourth pattern in the first frame structure for the first direction transmission of the sensing signal, and the fifth number of continuous uplink symbols and / or flexible symbols at the end of the fifth pattern for the first direction transmission of the sensing signal; or the receiving of the configuration information corresponding to the second node sent by the second node can comprise: receiving the sixth configuration information corresponding to the second node sent by the second node, the sixth configuration information being used for configuring the fourth number of continuous uplink symbols and / or flexible symbols at the end of the fourth pattern in the first frame structure for the second direction transmission of the sensing signal, and the fifth number of continuous uplink symbols and / or flexible symbols at the end of the fifth pattern for the second direction transmission of the sensing signal; wherein the fourth pattern and the fifth pattern are any two patterns with different time slot patterns in the plurality of patterns.

[0116] In an optional embodiment of the present disclosure, the method can further include: sending the configuration information to a third node, which is any node not performing sensing measurement. In this embodiment, the third node can be a terminal device within the communication range of the first node and not performing sensing measurement. The sending of the configuration information to the third node can include: sending, by the first node, a system information block 1 (SIB1) or a downlink control information (DCI) to the third node, the SIB1 or the DCI being used to indicate the configuration information. In this way, the terminal device can learn the relevant resource information of the current communication service, so as to avoid unnecessary sensing detection by the terminal device and avoid waste of energy consumption of the terminal device. On the other hand, when PUCCH / PUSCH performs repeated transmission and resource preemption occurs, the PUCCH / PUSCH that is postponed to the next time slot for transmission can be prevented from conflicting with the sensing signal. For example, FIG. 13 is a schematic diagram of conflict between sensing resources and communication resources according to an embodiment of the present disclosure. As shown in FIG. 13, the network configures three slots for transmission of communication information, such as “repeat 1”, “repeat 2” and “repeat 3” of PUCCH. At this time, a certain sensing signal configuration conflicts with the repeated PUCCH. If the terminal device is not notified of the relevant configuration information of the sensing resource, not only the second transmission will cause interference, but also one communication transmission will be missed, which affects the reliability of the network. If the terminal device is notified of the relevant configuration of the sensing resource in advance, the terminal device can cancel the second repeated transmission that will cause interference and perform communication transmission in the next slot, so as to ensure the communication performance.

[0117] In an optional embodiment of the present disclosure, the method can further include: receiving second signaling sent by the network device in a case where it is determined that the first node does not perform sensing measurement, the second signaling being used to notify that the configuration information is invalid.

[0118] The frame structure configuration method according to an embodiment of the present disclosure will be described below in combination with a specific application scenario.

[0119] In this example, node A and node B perform cooperative sensing, and the network device is a positioning server. First, a cooperative node cluster is formed and reported to the network. In the cooperative sensing network, the cooperative nodes (such as node A and node B) are organized together to perform cooperative work through the formation of the cooperative node cluster. The positioning server can configure the cooperative node sensing resource in a periodic manner. In this example, pattern1+pattern2 and A-to-B reception and B-to-A reception alternate sensing are configured.

[0120] Figure 14 is an exemplary schematic diagram of frame structure configuration of the embodiment of the present disclosure. As shown in Figure 14, the node A is configured with sensing resource, the sensing task period (denoted as the number of periods of pattern 1 and the number of periods of pattern 2) is set, and the sequence number of pattern 1 for sensing task and the sequence number of pattern 2 for sensing task are indicated. For the node A, L OFDM symbols are configured as S D from right to left for pattern 1 for sensing task, starting from the last uplink OFDM symbol of pattern 1, where L can be dynamically updated according to sensing requirement. Similarly, for the node A, M OFDM symbols are configured as S U from right to left for pattern 2 for sensing task, starting from the last uplink OFDM symbol of pattern 2, where M can be dynamically updated according to sensing requirement. The node B is configured with sensing resource in the same way. Exemplarily, the configuration information can include the sensing task period (the number of periods of pattern 1 and the number of periods of pattern 2, i.e. the first information mentioned above), the sequence number of pattern 1 for sensing task and the sequence number of pattern 2 for sensing task (i.e. the second information mentioned above), and the number of sensing resource duration symbols L and M (i.e. the third information mentioned above).

[0121] The following is an exemplary code of configuration information corresponding to the node A.

[0122] The following is an exemplary code of configuration information corresponding to the node B.

[0123] In some examples, the node A also needs to inform the terminals within the communication cell range of the node A which do not perform sensing measurement about the corresponding sensing frame structure; similarly, the node B also needs to inform the terminals within the communication cell range of the node B which do not perform sensing measurement about the corresponding sensing frame structure. Exemplarily, the node A or the node B can inform the communication terminals about the current non-communication service OFDM symbol through SIB1 system information corresponding to TDD-UL-DL-ConfigCommon, so as to avoid unnecessary listening detection of the terminals.

[0124] In the example, in order to avoid the interference of the downlink communication signals of the adjacent nodes on the cooperative sensing nodes, the cooperative nodes are configured with sensing resources in the uplink time slots and / or flexible time slots. Specifically, the last several symbols of the uplink time slots and / or flexible time slots of the cooperative nodes are configured as sensing symbols. On the one hand, the interference of the downlink communication signals on the sensing signals can be avoided. On the other hand, the GP overhead between the downlink time slots or symbols and the uplink time slots or symbols can be saved. In addition, in the two pattern modes of the frame structure, both the one-transmitting-one-receiving sensing mode and the receiving-transmitting-alternating sensing mode can be supported, the flexibility of the sensing service is increased, and the synchronous and high-precision positioning can be implemented.
