[0134] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things (IoT) device, narrowband Internet of Things (NB-IoT) device, satellite communication device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, and red-capped terminal, but is not limited thereto.

[0137] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected.

[0140] The embodiments of this application can be applied to Non-terrestrial Networks (NTN), 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 new radio (NR), 6th generation mobile communication system (6G), 6G new radio (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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), and IEEE IEEE 802.11 (Wi-Fi, registered trademark), IEEE 802.16 (WiMAX, registered trademark), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Narrow Band-IoT (NB-IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G / 6G).

[0141] In some embodiments, sensing technology can be used to acquire multi-dimensional sensing information of a target object (i.e., a sensing target).

[0142] In some embodiments, sensing technologies include many different types, such as: lidar, millimeter-wave radar, cameras (wherein the camera technology includes any one of the following: visual cameras, TOF cameras), sonar detection, infrared detection, and cellular sensing (e.g., sensing technologies based on 4G (e.g., LTE) or 5G (e.g., NR) or 6G cellular network technologies).

[0143] Optionally, the aforementioned cellular network sensing technology includes at least one of the following: communication base station sensing; communication terminal sensing.

[0144] Optionally, depending on the type of sensing device, the information about the target object that can be acquired may include at least one of the following:

[0145] Coordinate information (e.g., coordinates relative to the wireless signal receiver (e.g., distance, horizontal angle, and vertical angle));

[0146] Speed ​​information (e.g., moving speed and direction of movement relative to the wireless signal receiver);

[0147] Signal strength;

[0148] Behavioral pattern information (e.g., running, walking, approaching, falling, swinging, etc.); or weather information (e.g., rain, snow, etc.); or traffic information (e.g., congestion, accidents, etc.).

[0149] In some embodiments, with the continuous development of communication and sensing technologies, Integrated Sensing and Communications (ISAC) has a wide range of applications, such as high-precision positioning and imaging, and can be applied to scenarios such as smart transportation, smart homes, and smart healthcare.

[0150] In some embodiments, for an ISAC system, a wireless signal transmitter transmits radio waves, and a wireless signal receiver receives the radio waves. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal strength change. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes in the received signal, thereby obtaining information about the reflector (e.g., coordinate information / velocity information / signal strength / behavioral pattern information, etc.). The "signal transmitter" can be a terminal or a base station, and the "signal receiver" can be a terminal or a base station. The wireless signal transmitter and the wireless signal receiver can be the same device or different devices. Based on this, the wireless signal transmitter and the wireless signal receiver can have the following combinations:

[0151] Mode 1: Base station A transmits, base station B receives.

[0152] Mode 2: Base station A transmits, base station A receives.

[0153] Mode 3: Terminal A sends, Terminal B receives.

[0154] Mode 4: Terminal A sends, Terminal A receives.

[0155] Mode 5: Base station A transmits, terminal A receives.

[0156] Mode 6: Terminal A transmits, base station A receives.

[0157] When the wireless signal transmitter and receiver share a common site, this sensing method can be called mono-site sensing (e.g., mono-static sensing). When the wireless signal transmitter and receiver do not share a common site, this sensing method can be called bi-site sensing (e.g., bi-static sensing).

[0158] In some embodiments, during area detection or target tracking, the UE may need to achieve area coverage through the transmission signals (Tx) of multiple TRPs. To achieve faster measurement conversion of Tx for different TRPs, the network may pre-configure and inform the UE of the conversion time or conditions, allowing the terminal to automatically convert. The network may also instruct the terminal to switch the beam used for sensing transceiver via signaling. If the sensing beam and the communication beam are the same, changing the direction of the sensing beam to receive sensing signals will affect the transmission and reception of the communication link, thus affecting communication quality and violating the principle of sensing fusion.

[0159] However, switching between the sensing beam and the communication beam simultaneously each time can cause a complete user plane transition, involving DU, CU, Access and Mobility Management Function (AMF), and User Plane Function (UPF) processing, especially scenarios involving inter-DU and inter-CU interactions. In some embodiments, when the TRP where the target beam resides has a heavy communication load (e.g., limited TRP processing capacity), the TRP may only be able to provide sensing signal transmission for additional sensing services, but cannot accept new communication services. This handover will affect network load control. Even when the signal quality in the current user's cell is good, this also adds unnecessary network handovers and increases the network signaling load.

[0160] The beam switching method, communication equipment, communication system, storage medium, and program products provided in this application will be described in detail below with reference to the accompanying drawings.

[0161] Figure 2A is an interactive schematic diagram of a beam switching method according to an embodiment of this application. As shown in Figure 2A, this application embodiment relates to a beam switching method, which includes:

[0192] In step S2103, terminal 101 determines that the beam switching conditions are met and switches to the target beam corresponding to the target TRP.

[0193] In some embodiments, terminal 101 can determine whether the above measurement results meet the beam switching conditions.

[0203] In some embodiments, terminal 101 can automatically perform beam switching.

[0204] In some embodiments, the terminal 101 automatically performs beam switching only when it determines that both the sensing beam and the communication beam meet the corresponding beam switching conditions.

[0205] In some embodiments, the terminal 101 determines that the measurement result corresponding to the sensing beam meets the sensing beam switching condition and the measurement result corresponding to the communication beam meets the communication beam switching condition, switches the sensing beam to the target beam corresponding to the target sensing TRP, and switches the communication beam to the target beam corresponding to the target communication TRP.

[0206] Optionally, the target-aware TRP and the target-communication TRP can be the same TRP or different TRPs.

[0207] Optionally, the switched sensing beam and communication beam can be the same beam or different beams.

[0208] In some embodiments, the first information is used to indicate that the terminal 101 is allowed to perform the first operation if only the sensing beam meets the sensing beam switching condition or only the communication beam meets the communication beam switching condition.

[0209] Optionally, the first operation may be to switch only the beams that meet the switching conditions (i.e., the sensing beams or communication beams that meet the corresponding conditions) to the corresponding target TRP.

[0211] It is understood that in some embodiments, the first information mentioned above is used to indicate that if only the sensing beam meets the sensing beam switching condition, or only the communication beam meets the communication beam switching condition, the terminal 101 is not allowed to perform the first operation. In this case, the terminal 101 can only perform the switching of the sensing beam and the communication beam when it is determined that both the sensing beam and the communication beam meet the corresponding beam switching conditions.

[0212] In some embodiments, when terminal 101 determines to perform beam switching, it may send indication information to network device 102, which is used to instruct terminal 101 to perform beam switching.

[0213] That is, in some embodiments, the terminal 101 determines that the corresponding conditions are met and determines that beam switching should be performed, and can inform the network device 102 of the switching status by sending an instruction message.

[0222] It is understood that in some embodiments, after terminal 101 sends the first report mentioned above, network device 102 may also not instruct terminal 101 to perform beam switching based on network implementation or other means.

[0223] Furthermore, network device 102 determines to perform beam switching and sends switching instruction information to terminal 101.

[0229] As an example, network device 102 can pre-configure the Transmission Configuration Indication (TCI) state corresponding to different TRPs. Furthermore, it can use DCI, MAC CE, or RRC to tell terminal 101 to switch to the TCI state of the corresponding TRP and add an indication of whether the TCI state being switched is used for communication services, sensing services, or both.

[0230] As an example, network device 102 can also use MAC CE to carry an indication to tell terminal 101 to switch the beam to the corresponding TRP beam, and add an indication of whether the switch is for communication services, sensing services, or both.

[0231] As an example, network device 102 can also use an RRC message to carry an indication to tell terminal 101 to switch the beam to the corresponding TRP beam, and add an indication of whether the switch is for communication services, sensing services, or both.

[0308] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0309] The following is an exemplary description of the methods described in the above embodiments.

[0310] In some embodiments, when multiple TRPs are involved in sensing, and the UE (terminal) acts as the receiver, how to handle sensing services and communication services when the beam switches to different TRPs, and how to reduce the impact on user experience and network are issues that need to be considered and resolved.

[0311] In some embodiments of this application, a concurrent condition for communication and sensing services based on signal quality is introduced. The condition for simultaneous switching of communication and sensing services is met only when the beam signal quality of the communication service is lower than a preset threshold and the beam signal quality of the sensing service is also lower than a preset threshold at the same time.

[0312] In some embodiments of this application, the network can compare the beam switching conditions of the communication service and the beam switching conditions of the sensing service, and / or the load status of the target sensing service beam transmitting unit and / or the load status of the target communication service beam transmitting unit. In some embodiments, if both conditions are met, the sensing service and the communication service can be switched simultaneously. In some embodiments, if only the beam switching conditions of the sensing service are met, only the sensing service can be switched. In some embodiments, if only the beam switching conditions of the communication service are met, only the communication service can be switched.

[0313] In some embodiments of this application, the network can instruct the user whether to switch between sensing services and communication services simultaneously. The beam used for the communication service and the beam used for the sensing service may be the same or different beams.

[0314] In some embodiments, a concurrent conditional event based on beam signal quality is introduced for communication services and sensing services. When two conditions are met simultaneously, communication services and sensing services are switched at the same time.

[0315] In some embodiments, a switching condition based on signal quality is introduced for communication services and sensing services.

[0316] In some embodiments, the network can configure a threshold 1 based on beam signal quality for communication services and a threshold 2 based on beam signal quality for sensing services. It instructs the terminal that the condition for simultaneous switching between communication and sensing services is met only when the beam signal quality of the communication service is below threshold 1 and the beam signal quality of the sensing service is also simultaneously below threshold 2.

[0317] In some embodiments, the network can also configure the same signal quality threshold for communication services and sensing services. The condition for simultaneous switching of communication services and sensing services is met only when the signal quality of the beam of the communication service and the signal quality of the beam of the sensing service are both below the threshold.

[0318] In some embodiments, the network can be assigned a measurement signal using CSI-RS, SSB, sensingRS, or other reference signals. The network can also assign measurement thresholds based on measurements using CSI-RS, SSB, sensingRS, or other reference signals.

[0319] In some embodiments, the network may also indicate whether to allow handover (single handover or joint handover) or reporting (single reporting or simultaneous reporting) when only one condition is met.

[0320] Optionally, the network can inform the terminal via the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; via the user plane.

[0321] In some embodiments, the network may instruct the terminal whether to automatically switch when conditions are met, or whether it needs to report to the network.

[0322] Optionally, the network can display an indication when the RRC configuration conditions are met, suggesting whether the UE should allow automatic handover or must report the handover, and then wait for network commands. The network can also indicate whether the UE should allow automatic handover via MAC or DCI.

[0323] 1. Automatic service switching on the terminal.

[0324] In some embodiments, if the network instructs the terminal to switch automatically, the terminal will automatically switch services based on the conditions being met.

[0325] In some embodiments, if the network indicates that service switching can only be performed when two conditions are met simultaneously, then the terminal will switch the communication service and the sensing service together only when both the communication service and the sensing service conditions are met.

[0326] In some embodiments, if the network indicates that a handover can proceed as long as one condition is met, then the terminal will switch services when any one of the service handover conditions is met. For example, if the condition for sensing the beam of a service is met, the terminal switches the sensing service to the target TRP.

[0327] In some embodiments, the network may also instruct whether communication services and sensing services should be switched together if only one condition is met. If the network tells the terminal to switch together, then when either condition is met, the terminal will simultaneously switch both communication services and sensing services to the target TRP.

[0328] Furthermore, when deciding on a handover, the terminal can inform the network of the handover status before or after the handover. The terminal can inform the network through the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; and through the user plane.

[0329] 2. Network-controlled beam switching.

[0330] In some embodiments, if the network instructs the terminal to report when certain conditions are met, the terminal should report to the network when the conditions are met. The network can also determine whether a simultaneous switch is necessary based on other conditions, such as the communication load of the target TRP, to determine whether communication services and sensing services can be switched to the target TRP simultaneously.

[0331] In some embodiments, if the network indicates that reporting is only possible when both conditions are met simultaneously, then the terminal will only report the results of both communication and sensing services together when both conditions are met. Alternatively, the terminal may only report the condition that both conditions are met, such as simultaneous fulfillment. The terminal may also report both the condition that conditions are met and the corresponding signal quality.

[0332] In some embodiments, if the network indicates that a report can be made when a condition is met, then the terminal will report the service result when any service condition is met. Alternatively, the terminal may only report the fulfillment status; for example, if the perceived service is fulfilled, the terminal will report that the perceived service is fulfilled. The terminal may also report both the fulfillment status and the corresponding signal quality.

[0333] In some embodiments, if the network indicates that the results of both sensing and communication services should be reported simultaneously when a condition is met, then the terminal will report the results of both services when either condition is met. The terminal can indicate which condition is met, or it can report the signal quality of both sensing and / or communication services simultaneously.

[0334] Optionally, the terminal can inform the network via the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; via the user plane.

[0335] In some embodiments, the network indicates to the terminal whether communication services and sensing services are switched together via DCI, MAC, or RRC. The network can inform the terminal via the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; or via the user plane.

[0336] As an example, the network pre-configures TCI states for different TRPs and tells the UE to switch to the corresponding TCI state via DCI, MAC, or RRC, and adds an indication of whether the TCI state being switched is for communication services, awareness services, or a combination of communication and awareness services.

[0337] As an example, the network can also use the MAC CE to carry an indication to tell the UE to switch to the beam of the corresponding TRP, and add an indication of whether the switch is for communication services, sensing services, or both.

[0338] As an example, the network can also use RRC messages to carry an indication to tell the UE to switch to the corresponding TRP beam, and add an indication of whether the switch is for communication services, sensing services, or both.

[0339] In some embodiments, unless contradictory, the optional implementations in this embodiment can be implemented as independent embodiments, and the optional implementations in this embodiment can also be combined arbitrarily. The technical features of different feasible implementations in this embodiment can be combined to form new optional implementations based on their inherent logical relationships.

The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
