[0026] The embodiments of this disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure. It should be noted that, unless otherwise specified, the embodiments of this disclosure and the features in the embodiments can be combined with each other.

[0027] For ease of understanding, the terminology used in the embodiments of this disclosure will be introduced first.

[0028] 1. Perceiving business

[0029] Sensing services refer to a series of services based on the fusion of communication and sensing technologies. These services enable the acquisition, analysis, and utilization of information about target objects or the environment through the sensing and processing of wireless signals. Utilizing the sensing capabilities within the communication system, by analyzing direct, reflected, and scattered radio wave signals, information about target objects or the environment is obtained, enabling functions such as positioning, ranging, velocity measurement, imaging, detection, identification, and environmental reconstruction. When terminal devices execute sensing services, they can receive or transmit sensing signals.

[0030] 2. Communication services

[0031] Communication services refer to the information transmission, exchange, and processing services provided to users through communication facilities or networks. These services encompass the transmission and processing of various types of information, including voice, data, and images. When terminal equipment performs communication services, it can receive or send communication signals.

[0032] 3. ISAC technology

[0033] Research on ISAC technology mainly focuses on scenarios such as Transmit-Receive Point (TRP) - TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, and UE monostatic. During the design process, ISAC systems need to simultaneously consider the service requirements of communication and sensing.

[0034] The six scenarios mentioned above can be explained in detail.

[0035] The base station transmits and receives signals (or gNB transmits and receives signals, i.e., TRP monostatic). The base station sends sensing signals, which, after passing through the environment or objects in the environment, are received and measured by the same base station as reflected / scattered waves.

[0036] Base station A transmits and base station B receives (or gNB A transmits and base station B receives, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, which passes through the environment or objects in the environment, and base station B receives and measures the reflected / scattered waves.

[0037] The terminal transmits and the base station receives (or the UE transmits and the gNB receives, i.e., UE-TRP bistatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected / scattered waves.

[0038] The base station transmits and the terminal receives (or the gNB transmits and the UE receives, i.e., TRP-UE bistatic). The base station sends a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.

[0039] Terminal-based self-transmission and self-reception (or UE-based self-transmission and self-reception, i.e., UE monostatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the same terminal receives and measures the reflected / scattered waves.

[0040] Terminal A transmits and B receives (or UE A transmits and B receives, i.e., UE-UE bistatic). Terminal A sends a sensing signal, which passes through the environment or objects in the environment, and Terminal B receives and measures the reflected / scattered waves.

[0041] 4. Time or Frequency Division Duplex (XDD).

[0042] XDD supports configuring an uplink (UL) subband in a downlink slot to reduce feedback latency and increase uplink service performance. For example, there are two types of terminals: one is a legacy UE, which cannot recognize the UL subband, and the other is a new UE that supports Subband Full-Duplex (SBFD), which can recognize the UL subband.

[0043] 5. Subband Full Duplex (SBFD)

[0044] In the field of wireless communication, SBFD refers to Subband Full-Duplex technology. This is a new type of full-duplex communication that achieves simultaneous uplink and downlink data transmission within a single spectrum by dividing it into non-overlapping uplink and downlink subbands, thus enabling full-duplex communication. This differs from traditional Time Division Duplex (TDD) and Frequency Division Duplex (FDD) because it does not require strict time division or dedicated frequency resources to avoid uplink and downlink interference. Instead, it uses advanced signal processing techniques to suppress self-interference and other interference, thereby improving spectral efficiency and reducing latency. Terminals supporting SBFD can adapt to this new full-duplex mode, enjoying higher data transmission rates and lower latency services.

[0045] This disclosure presents a communication method, communication device, and communication system.

For example, embodiments of this disclosure can also be applied to structures that replace communication between access network devices, core network devices, or network devices and terminals with communication between multiple terminals (e.g., also referred to as device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the structure can also be configured such that the terminal has all or part of the functions of the access network device.

The communication processing system may include all or some of the subjects in FIG1, or may include other subjects other than those in FIG1. ​​The number and form of each subject are arbitrary. The connection relationship between the subjects is illustrative. The subjects may not be connected to each other or may be connected in any way. The connection may be a direct connection or an indirect connection, a wired connection or a wireless connection.

[0153] The embodiments disclosed herein can be applied to satellite communications, Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G NR, Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0154] As shown in Figure 2, in a network environment, there exists a UE A that supports SBFD and a UE B that does not support SBFD. When UE A transmits a sensing signal, it can do so in the uplink subband. However, UE B cannot recognize the uplink subband, meaning that when UE B is transmitting downlink signals (i.e., receiving communication signals) within the corresponding time unit, the downlink transmission will conflict with UE A's uplink transmission of the sensing signal. From an inter-UE multiplexing perspective, if the NR mechanism is reused, and assuming either UE is of low priority, the low-priority UE needs to listen to either DL PI or UL CI. For example, if UE A's sensing service is of low priority, the network device can cancel UE A's transmission by sending UL CI. However, if both UE A and UE B are high-priority services, UE A does not need to listen to UL CI, and UE B does not need to listen to DL PI. UE B will incorrectly receive the sensing signal sent by UE A, leading to incorrect judgment.

[0155] In a similar scenario, as shown in Figure 3, a network environment contains both UE A (which does not support SBFD) and UE B (which does support SBFD). When UE A is triggered to receive a sensing service, UE A needs to receive sensing signals on downlink resources. UE B, on the other hand, can identify the uplink subband and will normally transmit uplink communication signals in the uplink subband. At this time, UE A may mistakenly interpret the communication signals transmitted by UE B as sensing signals, leading to an incorrect judgment.

[0156] To address the aforementioned issues, this embodiment identifies new behaviors of some terminal devices, meaning that the terminal can determine its communication behavior based on first information. Furthermore, it identifies scheduling restrictions on sensing and communication services by some network devices, meaning that the network devices can determine their communication behaviors based on second information. These communication behaviors can be used to avoid conflicts between sensing and communication services.

[0157] Furthermore, to illustrate the specific execution process of the above-described communication system, Figure 4 shows a schematic diagram of a communication method according to an embodiment of this disclosure. The method, applied to the above-described communication system, as shown in Figure 4, may include the following steps:

[0158] Step S201: The network device sends the first information to the terminal.

[0159] In this embodiment, within a network, the types of services that network devices and terminals interact with may include sensing services and communication services. For sensing services, the network device and the terminal jointly complete the transmission and reception of sensing signals; or the network device configures a first resource for the terminal, and the terminal completes the transmission and reception of sensing signals independently based on the first resource; or the network device configures a first resource for the terminal, and multiple terminals complete the transmission and reception of sensing signals. The priority of sensing services includes high priority, low priority, etc. For communication services, the network device and the terminal device jointly complete the transmission and reception of communication signals. The priority of communication services includes high priority, low priority, etc. In this scenario, to avoid conflicts between sensing services and communication services, the processes shown in steps S201 to S202 can be executed.

[0160] In some embodiments, the terminal receives first information sent by the network device, which may be indication information or signaling messages, etc. This first information can be used to determine the terminal's communication behavior.

[0161] In some embodiments, the first information is carried by at least one of the following:

[0162] Radio Resource Control (RRC) messages; Downlink Control Information (DCI); Media Access Control (MAC) Control Element (CE); Master Information Block (MIB); System Information Block (SIB).

[0163] Step S202: The terminal determines the communication behavior based on the first information.

[0164] In some embodiments, communication behavior can be used to avoid conflicts between sensing services and communication services. For example, as shown in Figure 2, for UE A that supports SBFD and UE B that does not support SBFD, the communication behavior of UE A and / or UE B can be determined based on first information, so that the downlink receiving communication signal of UE B does not conflict with the uplink transmitting sensing signal of UE A, and UE B will not incorrectly receive the sensing signal sent by UE A.

[0165] For example, as shown in Figure 3, for UE A which does not support SBFD and UE B which supports SBFD, the communication behavior of UE A and / or UE B can be determined based on the first information, so that the uplink transmission communication signal of UE B does not conflict with the downlink reception sensing signal of UE A, and UE A cannot mistakenly take the communication signal sent by UE B as the sensing signal.

[0166] In some embodiments, the communication behavior includes at least one of the following: A1, B1, C1, D1, E1:

[0167] A1. The terminal does not expect the network device to schedule sensing services in the sub-band of SBFD. In some examples, the network device's scheduling of sensing services in the sub-band of SBFD includes: the network device scheduling the terminal to transmit sensing signals in the sub-band, and / or the network device transmitting sensing signals in the sub-band.

[0168] For example, a terminal's expectation that the network device will not schedule sensing signals in the sub-band of SBFD includes: not expecting the network device to schedule the terminal to send sensing signals in the sub-band; and / or not expecting the network device to schedule the terminal to receive sensing signals in the sub-band; and / or not expecting the network device to send sensing signals in the sub-band; and / or not expecting the network device to receive sensing signals in the sub-band. In this way, conflicts between sensing services and communication services can be avoided.

[0169] B1. The terminal does not expect the network device to schedule sensing services in the time unit where the sub-band of the SBFD is located. In some examples, the scheduling of sensing services by the network device in the time unit where the sub-band of the SBFD is located includes: the network device scheduling the terminal to transmit sensing signals in that time unit, and / or the network device transmitting sensing signals in that time unit. In some examples, the time unit may be a frame, subframe, slot, symbol, resource block (RB), etc.

[0170] For example, a terminal's expectation that the network device will not schedule sensing signals in the solt of the sub-band of the SBFD includes: not expecting the network device to schedule the terminal to send sensing signals in the solt of the sub-band of the SBFD; not expecting the network device to schedule the terminal to receive sensing signals in the solt of the sub-band of the SBFD; not expecting the network device to send sensing signals in the solt of the sub-band of the SBFD; and not expecting the network device to receive sensing signals in the solt of the sub-band of the SBFD. In this way, conflicts between sensing services and communication services can be avoided.

[0171] C1. Terminals do not expect network devices to schedule overlapping time-frequency domain resources for sensing services and communication services.

[0172] For example, a terminal does not expect the time-frequency domain resources of communication services and sensing services scheduled by network devices to overlap. The sensing services may include uplink sensing services and downlink sensing services, and the communication services may include uplink communication services and downlink communication services. In this way, conflicts between sensing services and communication services can be avoided.

[0173] For C1, in some examples, the terminal does not expect the network device to schedule overlapping time-frequency domain resources for sensing services and communication services, including: the terminal does not expect the network device to schedule overlapping time-frequency domain resources for sensing services and communication services that are both of the first priority. The first priority can be a specific priority, such as high priority.

[0174] For example, a terminal does not expect the network device to schedule time-frequency domain resources that overlap with those of high-priority communication services and high-priority sensing services. These sensing services may include uplink sensing services and downlink sensing services, and the communication services may include uplink communication services and downlink communication services. In this way, conflicts between sensing services and communication services can be avoided.

[0175] D1. The terminal listens for cancellation signaling sent by the network device. This cancellation signaling can be used by the terminal to determine whether to cancel the execution of a scheduled sensing service or communication service. This embodiment allows the terminal to listen for cancellation signaling sent by the network device. When the network device determines that a sensing service or communication service is about to occur, it can send a cancellation signaling to the corresponding terminal, enabling the terminal to determine whether to cancel the execution of the scheduled sensing service or communication service, thus avoiding conflicts between sensing services and communication services.

[0176] In some embodiments, the cancellation signaling may include at least one of the following X2, Y2, Z2:

[0177] X2, UL CI. UL CI is used by the terminal to determine whether to cancel the execution of the scheduled uplink sensing service or uplink communication service.

[0178] Y2, DL PI. DL PI is used by the terminal to determine whether to cancel the execution of the scheduled downlink sensing service or downlink communication service.

[0179] Z2. Third Indication: The third indication is used to determine the cancellation indication for uplink and / or downlink services. For example, the third indication may be a New Cancellation Indication (NCI), which is an indication capable of indicating the cancellation of uplink and / or downlink services.

[0180] In some embodiments, determining the terminal listening cancellation signaling based on the first information includes at least one of the following M3 and N3:

[0181] M3. Determine if the terminal is listening for cancellation signaling based on the first condition. If the first condition is met, the terminal needs to listen for cancellation signaling; for example, the first condition can be indicated to the terminal by the network device. Besides this method, the first condition can also be an implicit indication condition predefined by the protocol.

[0182] In some examples, the first condition includes at least one of the following: a1, b1, c1, d1, e1, f1, g1:

[0183] a1. The terminal is configured with SBFD; for example, when the terminal is configured with SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0184] b1. The terminal determines that other terminals in the same cell support SBFD; for example, when the terminal learns that other terminals in the same cell support SBFD, the terminal needs to listen for cancellation signaling sent by the network device. Or, when the terminal is indicated that there are other terminals in the same cell that support SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0185] c1. The terminal is scheduled to perform sensing services in the sub-band of SBFD; for example, when the terminal is scheduled to send sensing signals in the sub-band of SBFD, the terminal needs to listen for cancellation signaling sent by the network device. Or, when the terminal is scheduled to receive sensing signals in the sub-band of SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0186] d1. The terminal is scheduled to perform sensing services in the time unit of the sub-band of the SBFD; for example, when the terminal is scheduled to send sensing signals in the slot of the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device; or when the terminal is scheduled to receive sensing signals in the slot of the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0187] e1. The terminal is scheduled to perform communication services in the sub-band of the SBFD; for example, when the terminal is scheduled to send communication signals in the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device; or when the terminal is scheduled to receive communication signals in the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0188] f1. The terminal is scheduled to perform communication services in the time unit of the sub-band of the SBFD; for example, when the terminal is scheduled to send communication signals in the slot of the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device; or when the terminal is scheduled to receive communication signals in the slot of the sub-band of the SBFD, the terminal needs to listen for cancellation signaling sent by the network device.

[0189] g1. The sensing or communication service scheduled by the terminal is a second-priority service. In some examples, the second priority can be high priority, low priority, or not the highest priority, etc.

[0190] For example, when a terminal is scheduled for a high-priority service, it needs to listen for cancellation signaling sent by the network device. High-priority services may include: high-priority uplink communication services, high-priority downlink communication services, high-priority uplink sensing services, high-priority downlink sensing services, etc.

[0191] In one implementation, when a terminal is scheduled to send high-priority uplink communication services, the terminal listens for the UL CI.

[0192] In one implementation, when a terminal is scheduled to receive high-priority downlink communication services, the terminal listens for DL ​​PI.

[0193] In one implementation, when a terminal is scheduled to send a high-priority uplink sensing service, the terminal listens to the UL CI.

[0194] In one implementation, when a terminal is scheduled to receive high-priority downlink sensing services, the terminal listens for DL ​​PI.

[0195] In some embodiments, the sensing service or communication service scheduled by the terminal is determined to be a non-highest priority service based on at least one of the following (1) to (8):

[0196] (1) Sensing services have a higher priority than communication services;

[0197] (2) The low priority of sensing services is higher than the low priority of communication services.

[0198] (3) Perception services have lower priority than communication services;

[0199] (4) Perception services have a higher priority than communication services;

[0200] (5) Sensing services have a lower priority than communication services;

[0201] (6) The low priority of sensing services is lower than that of communication services.

[0202] (7) The low priority of sensing services is lower than the high priority of communication services;

[0203] (8) Perception services have a higher priority than communication services.

[0204] This is equivalent to introducing multiple priority levels at the physical layer. For example, if a terminal determines that the sensing service or communication service it is scheduled is not the highest priority service based on at least one of the principles in (1) to (8), the terminal needs to listen to the cancellation signal sent by the network device and determine whether to cancel the execution of the scheduled sensing service or communication service based on the listened cancellation signal, which can avoid the conflict between sensing service and communication service.

[0205] N3. Determine the terminal listening cancellation signaling according to the first instruction.

[0206] The first indication may be an indication message used to indicate whether the terminal needs to listen for cancellation signaling. This first indication may be carried in at least one of RRC signaling, MAC CE, DCI, and UCI.

[0207] When the first instruction is sent from the network device to the terminal, the network device decides whether the terminal needs to listen for the cancellation signal.

[0208] When the terminal sends the first instruction to the network device, the terminal reports to the network device whether it will listen for cancellation signaling. For example, the terminal may report to the network device via the first instruction whether it will listen for cancellation signaling during an upcoming listening opportunity; or, the terminal may report to the network device via the first instruction whether it will continuously listen for cancellation signaling during listening opportunities; or, the terminal may report to the network device via the first instruction whether it will continuously listen for cancellation signaling during listening opportunities where the indicated range overlaps with the sub-band of the SBFD; or, the terminal may report to the network device via the first instruction whether it will continuously listen for cancellation signaling during listening opportunities where the indicated range overlaps with the sub-band of the SBFD; or, the terminal may report to the network device via the first instruction whether it will continuously listen for cancellation signaling during listening opportunities where the indicated range overlaps with the slot containing the sub-band of the SBFD; or, the terminal may report to the network device via the first instruction whether it will continuously listen for cancellation signaling during listening opportunities where the indicated range overlaps with the slot containing the sub-band of the SBFD.

[0209] In one implementation, the first indication is a 1-bit DCI field. When the bit value is 0, it indicates that the terminal does not need to listen for cancellation signaling sent by the network device; when the bit value is 1, it indicates that the terminal needs to listen for cancellation signaling sent by the network device. Alternatively, when the bit value is 1, it indicates that the terminal does not need to listen for cancellation signaling sent by the network device; when the bit value is 0, it indicates that the terminal needs to listen for cancellation signaling sent by the network device.

[0210] In some examples, the NCI (Cancellation Indicator) is a cancellation indication only for high-priority services. These high-priority services may include: high-priority uplink communication services, high-priority downlink communication services, high-priority uplink-aware services, high-priority downlink-aware services, etc. When a terminal is scheduled for a high-priority service, it needs to listen to the NCI to determine whether the scheduled high-priority service has been cancelled.

[0211] In one implementation, the NCI is a UE-specific DCI containing a 1-bit listening indication field. A bit value of 0 indicates that the service has been cancelled / preempted; a bit value of 1 indicates that the service has not been cancelled / preempted. Alternatively, a bit value of 1 indicates that the service has been cancelled / preempted; a bit value of 0 indicates that the service has not been cancelled / preempted.

[0212] In one implementation, NCI is a UE group DCI containing multiple bit listening indication fields, which are used to indicate whether the service on the corresponding time-frequency domain resource has been canceled / preempted.

[0213] E1. The terminal determines whether to execute the first service based on the absolute priority of the first service being scheduled. The first service is either a sensing service or a communication service.

[0214] In some examples, absolute priority can include absolute highest priority, absolute lowest priority, etc. For example, if the first service (sensing service or communication service) scheduled for a terminal has the absolute highest priority, then it does not need to consider whether there will be a conflict between the sensing service and the communication service, and it will execute the first service.

[0215] For example, if the first service (sensing service or communication service) scheduled for the terminal has the absolute lowest priority, then it needs to listen for the cancellation signal sent by the network device. This cancellation signal is used by the terminal to determine whether to cancel the execution of the scheduled first service in order to avoid conflicts between sensing service and communication service.

[0216] In some examples, the terminal can determine the absolute priority of the first service based on a second instruction. In some examples, this second instruction can be carried in at least one of RRC signaling, MAC CE, DCI, and UCI.

[0217] In this embodiment, some new behaviors of terminal devices are determined, that is, the terminal can determine its communication behavior based on the first information. Furthermore, some scheduling restrictions of network devices on sensing services and communication services are determined, that is, the network devices can determine their communication behavior based on the second information. These communication behaviors can be used to avoid conflicts between sensing services and communication services.

[0218] To illustrate the specific execution process of the terminal, Figure 5 shows a flowchart of a communication method according to an embodiment of this disclosure. When applied to the terminal side, the method may include the following steps.

[0219] Step S301: The terminal determines the first information.

[0220] In this embodiment, within a network, the service types for interaction between network devices and terminals may include sensing services and communication services.

The priority of sensing services includes high priority, low priority, etc. For communication services, the network device and the terminal device jointly complete the transmission and reception of communication signals. The priority of communication services includes high priority, low priority, etc. In this scenario, to avoid conflicts between sensing services and communication services, the processes shown in steps S301 to S302 can be executed.

[0221] In some embodiments, the first information may be determined according to a predefined protocol, and the first information may be used to determine the communication behavior of the terminal.

[0222] In some embodiments, the first information may be indicated by a network device. Accordingly, the terminal determining the first information may include: the terminal receiving the first information sent by the network device, which can be used to determine the terminal's communication behavior.

[0223] Step S302: The terminal determines the communication behavior based on the first information.

[0224] In some embodiments, communication behavior can be used to avoid conflicts between sensing services and communication services.

[0225] In some embodiments, the communication behavior includes at least one of the following: A1, B1, C1, D1, E1:

In some examples, the time unit can be a frame, subframe, slot, symbol, RB, etc.

[0228] C1. Terminals do not expect network devices to schedule overlapping time-frequency domain resources for sensing services and communication services.

The first priority can be a specific priority, such as high priority.

[0230] D1. The terminal listens for cancellation signaling sent by the network device. This cancellation signaling can be used by the terminal to determine whether to cancel the execution of a scheduled sensing service or communication service. This embodiment allows the terminal to listen for cancellation signaling sent by the network device. When the network device determines that a sensing service or communication service is about to occur, it can send a cancellation signaling to the corresponding terminal, enabling the terminal to determine whether to cancel the execution of the scheduled sensing service or communication service, thus avoiding conflicts between sensing services and communication services.

[0231] In some embodiments, the cancellation signaling may include at least one of the following X2, Y2, Z2:

[0232] X2, UL CI. UL CI is used by the terminal to determine whether to cancel the execution of the scheduled uplink sensing service or uplink communication service.

[0233] Y2, DL PI. DL PI is used by the terminal to determine whether to cancel the execution of the scheduled downlink sensing service or downlink communication service.

[0234] Z2. Third Instruction: The third instruction is used to determine the cancellation instruction for uplink and / or downlink services. For example, the third instruction can be an NCI, which is an instruction capable of indicating the cancellation of uplink and / or downlink services.

[0236] M3. Determine if the terminal is listening for cancellation signaling based on the first condition. If the first condition is met, the terminal needs to listen for cancellation signaling; for example, the first condition can be indicated to the terminal by the network device. Besides this method, the first condition can also be an implicit indication condition predefined by the protocol.

[0237] In some examples, the first condition includes at least one of the following: a1, b1, c1, d1, e1, f1, g1:

[0238] a1. The terminal is configured with SBFD.

[0239] b1. The terminal determines that the terminal in the same cell supports SBFD.

[0240] c1. The terminal is scheduled to perform sensing services in the sub-band of SBFD.

[0252] (7) The low priority of sensing services is lower than the high priority of communication services;

[0253] (8) Perception services have a higher priority than communication services.

[0254] This is equivalent to introducing multiple priority levels at the physical layer. For example, if a terminal determines that the sensing service or communication service it is scheduled is not the highest priority service based on at least one of the principles in (1) to (8), the terminal needs to listen to the cancellation signal sent by the network device and determine whether to cancel the execution of the scheduled sensing service or communication service based on the listened cancellation signal, which can avoid the conflict between sensing service and communication service.

[0255] N3. Determine the terminal listening cancellation signaling according to the first instruction.

[0256] E1. The terminal determines whether to execute the first service based on the absolute priority of the first service being scheduled. The first service is either a sensing service or a communication service.

[0257] In some examples, absolute priority can include absolute highest priority, absolute lowest priority, etc. For example, if the first service (sensing service or communication service) scheduled for a terminal has the absolute highest priority, then it does not need to consider whether there will be a conflict between the sensing service and the communication service, and it will execute the first service.

[0258] For a detailed description of the specific examples in this embodiment, please refer to the corresponding description of the embodiment in Figure 4, which will not be repeated here.

[0259] In this embodiment, some new behaviors of terminal devices are determined, that is, the terminal can determine its communication behavior based on the first information. Furthermore, some scheduling restrictions of network devices on sensing services and communication services are determined, that is, the network devices can determine their communication behavior based on the second information. These communication behaviors can be used to avoid conflicts between sensing services and communication services.

[0260] Figure 6 shows a flowchart of a communication method according to an embodiment of the present disclosure. As shown in Figure 6, the method is applied to the network device side and may include the following steps.

[0261] Step S401: The network device determines the second information.

[0262] In this embodiment, within a network, the service types for interaction between network devices and terminals may include sensing services and communication services. For sensing services, the network device and the terminal jointly complete the transmission and reception of sensing signals; or the network device configures a first resource for the terminal, and the terminal completes the transmission and reception of sensing signals independently based on the first resource; or the network device configures a first resource for the terminal, and multiple terminals complete the transmission and reception of sensing signals. The priority of sensing services includes high priority, low priority, etc. For communication services, the network device and the terminal device jointly complete the transmission and reception of communication signals. The priority of communication services includes high priority, low priority, etc. In this scenario, to avoid conflicts between sensing services and communication services, the processes shown in steps S401 to S402 can be executed.

[0263] In some embodiments, the second information may be determined according to a protocol predefined, and the first information may be used to determine the communication behavior of the network device.

[0264] In some embodiments, the second information may be indicated by a first network element (which may be a network element in the network). Accordingly, determining the second information by the network device may include: the network device receiving the second information sent by the first network element, which can be used to determine the communication behavior of the network device.

[0265] Step S402: The network device determines the communication behavior based on the second information.

[0266] In some embodiments, communication behavior can be used to avoid conflicts between sensing services and communication services. For example, as shown in Figure 2, for UE A that supports SBFD and UE B that does not support SBFD, the communication behavior of the network devices can be determined according to the second information, and UE A and / or UE B can be scheduled accordingly so that the downlink receiving communication signal of UE B does not conflict with the uplink transmitting sensing signal of UE A, and UE B will not incorrectly receive the sensing signal sent by UE A.

[0267] For example, as shown in Figure 3, for UE A which does not support SBFD and UE B which does support SBFD, the communication behavior of the network devices can be determined based on the second information, and UE A and / or UE B can be scheduled accordingly so that the uplink transmission communication signal of UE B does not conflict with the downlink reception sensing signal of UE A, and UE A cannot mistakenly take the communication signal sent by UE B as the sensing signal.

[0268] In some embodiments, the communication behavior includes at least one of the following: A2, B2, C2, D2, F2:

[0269] A2. Network devices are not allowed to schedule sensing services in the sub-band of SBFD; in some examples, network devices are not allowed to schedule sensing services in the sub-band of SBFD, including: network devices are not allowed to schedule terminals to transmit sensing signals in the sub-band, and / or network devices are not allowed to transmit sensing signals in the sub-band.

[0270] For example, network devices are prohibited from scheduling sensing signals in the sub-band of SBFD, including: prohibiting scheduling terminals from sending sensing signals in the sub-band; and / or prohibiting scheduling terminals from receiving sensing signals in the sub-band; and / or prohibiting network devices from sending sensing signals in the sub-band; and / or prohibiting network devices from receiving sensing signals in the sub-band. In this way, conflicts between sensing services and communication services can be avoided.

[0271] B2. Network devices are not allowed to schedule sensing services within the time unit of a sub-band of an SBFD. In some examples, network devices are not allowed to schedule sensing services within the time unit of a sub-band of an SBFD, including: network devices are not allowed to schedule terminals to transmit sensing signals in that time unit, and / or network devices are not allowed to transmit sensing signals in that time unit. In some examples, the time unit can be a frame, subframe, slot, symbol, RB, etc.

[0272] For example, network devices are prohibited from scheduling sensing signals in the slot containing the SBFD's sub-band. This includes: prohibiting scheduling terminals from sending sensing signals in the slot containing the SBFD's sub-band; and / or prohibiting scheduling terminals from receiving sensing signals in the slot containing the SBFD's sub-band; prohibiting network devices from sending sensing signals in the slot containing the SBFD's sub-band; and prohibiting network devices from receiving sensing signals in the slot containing the SBFD's sub-band. In this way, conflicts between sensing services and communication services can be avoided.

[0273] C2. Network devices are not allowed to schedule overlapping time-frequency domain resources between sensing services and communication services.

[0274] For example, network devices do not allow overlapping time-frequency domain resources between scheduling communication services and sensing services. The sensing service may include uplink sensing services and downlink sensing services; the communication service may include uplink communication services and downlink communication services. In this way, conflicts between sensing services and communication services can be avoided.

[0275] For C2, in some examples, network devices do not allow overlapping time-frequency domain resources for sensing services and communication services, including: network devices do not allow overlapping time-frequency domain resources for sensing services and communication services that are both of the first priority. The first priority can be a specific priority, such as high priority.

[0276] For example, network devices do not allow overlapping time-frequency domain resources between high-priority communication services and high-priority sensing services. The sensing service may include uplink sensing services and downlink sensing services; the communication service may include uplink communication services and downlink communication services. In this way, conflicts between sensing services and communication services can be avoided.

[0277] D2. The network device sends a first instruction to the terminal or receives a first instruction sent by the terminal. The first instruction is used to determine whether the terminal is listening to the cancellation signaling sent by the network device. The cancellation signaling is used by the terminal to determine whether to cancel the execution of the scheduled sensing service or communication service.

[0278] F2. The network device sends a second instruction to the terminal or receives a second instruction sent by the terminal. The second instruction is used to determine the absolute priority of the first service scheduled by the terminal. The first service is a sensing service or a communication service. The absolute priority is used by the terminal to determine whether to execute the first service.

[0279] In some examples, the first instruction and / or the second instruction is carried by at least one of the following:

[0280] RRC signaling; MAC CE; DCI; UCI.

[0281] In some examples, cancellation signaling includes at least one of the following:

[0282] ULCI; DLPI; Third Instruction, which is used to determine the cancellation instruction for uplink and / or downlink services.

[0283] For a detailed description of the specific examples in this embodiment, please refer to the corresponding descriptions of the embodiments in Figures 4 and 5, which will not be repeated here.

[0284] In this embodiment, some new behaviors of terminal devices are determined, that is, the terminal can determine its communication behavior based on the first information. Furthermore, some scheduling restrictions of network devices on sensing services and communication services are determined, that is, the network devices can determine their communication behavior based on the second information. These communication behaviors can be used to avoid conflicts between sensing services and communication services.
