As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0135] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. 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.

Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0137] In some embodiments, the sensing system integrates a radar system on top of a communication system in related technologies, and senses information such as the distance, speed, and angle of targets in the surrounding environment by sending sensing signals. As shown in Figure 1B, sensing systems can generally be divided into two types according to their sensing modes. The first type is mono-static sensing mode, where the transceiver can be an access network device or a terminal. The second type is bi-static sensing mode, where the transmitter can be an access network device or a terminal, and the receiver can be both an access network device and a terminal.

[0138] In communication beam management, the selection of transmit and receive beam pairs is usually completed based on three processes: P1, P2, and P3. For example, in the downlink beam management process P1, the access network device uses the same transmit beam to send a set of different reference signals. The terminal uses different receive beams to receive the reference signals and measures parameters such as layer 1 (L1) reference signal receive power (RSRP) / signal-to-interference ratio (SINR). The access network device switches to another transmit beam and repeats the above process. After the access network device has traversed the transmit beams, the terminal reports the reference signal ID corresponding to the highest L1-RSRP / SINR, thereby determining the optimal initial transmit / receive beam pair. In the downlink beam management process P2, the access network device sends different reference signals through different narrow beams within the wide transmit beam envelope determined in the P1 process. The terminal uses a fixed receive beam to receive the reference signals and measures parameters such as L1-RSRP / SINR. The terminal reports the reference signal ID corresponding to the highest L1-RSRP / SINR, thereby determining the optimal narrow transmit beam and completing the transmit beam improvement. However, in both P1 and P2 processes, the terminal only reports the optimal reference signal ID, that is, the terminal only reports the optimal transmit beam of the access network device, and does not explicitly or implicitly report the terminal's receive beam.

[0139] In related technologies, there is still no solution for beam management in sensing systems, which is an urgent problem to be solved.

[0140] Based on this, this disclosure provides an information transmission method and apparatus, wherein the method executed by a first device includes: sending sensing information to a second device, wherein the sensing information includes sensing beam information related to the sensing process performed by the first device. Thus, by sending the sensing beam information related to the sensing process performed by the first device to the second device, and managing the sensing beam information related to the sensing process at the second device, the performance of the sensing system can be improved.

The first device determines one or more sensing receiving beams for sensing the sensed target based on the auxiliary information, wherein the Doppler frequency range of one or more paths associated with the one or more sensing receiving beams includes the time delay range in which the sensed target appears.

[0257] S203B, the first device uses the sensing receiving beam to receive the sensing signal transmitted by the second device using the sensing transmitting beam.

[0258] In this embodiment, the first device and the second device adopt a dual-station sensing mode. The second device uses a sensing transmit beam to send sensing signals to the first device, and the first device uses a sensing receive beam to receive the sensing signals. Optionally, the first device is a terminal, and the second device is an access network device. Optionally, both the first and second devices are access network devices.

[0259] It is understandable that the sensed signal can also be called the sensed reference signal, reference signal, etc.

[0260] In some embodiments, the second device may also transmit sensing signals to other devices besides the first device using one or more sensing transmit beams.

[0261] In some embodiments, the first device may also receive sensing signals from other devices besides the second device using one or more sensing receiving beams.

[0262] S204B, the first device measures the sensing signal and determines the measurement value of the corresponding sensing quantity of the beam pair composed of the sensing receiving beam and the sensing transmitting beam.

[0263] The optional implementations of S204B can be found in the optional implementations of S204A in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0264] S205B, the first device determines the sensing information based on the measured value of the sensing quantity.

[0265] The optional implementations of S205B can be found in the optional implementations of S205A in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0266] S206B, the first device sends sensing information to the second device.

[0267] The optional implementations of S206B can be found in the optional implementations of S206A in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0268] In some embodiments, the sensing information includes sensing beam information of the first device performing the sensing process.

[0269] For example, as shown in Figure 3A, the second device transmits M different or identical sensing signals through M different sensing transmit beams, corresponding to sensing signal IDs or sensing transmit beam IDs {1,…,M}, respectively. The first device receives the aforementioned sensing signals through N sensing receive beams. The optimal number of sensing receive beam pairs K can be configured by the network, predefined by the protocol, or determined based on the measurement results of the first device and a power threshold pre-set by the protocol. The first device determines the optimal K sensing transmit / receive beam pairs IDs {m1-n1,m2-n2,…,mK-nK} based on the metric values ​​of the sensing measurements, and measures and obtains the delay, power, Doppler, angle, etc., corresponding to the strongest P-path contained in each sensing transmit / receive beam pair. For example, the reported path is determined based on the power threshold configured by the network side or other nodes or the power threshold pre-defined by the protocol. When the power of the path is greater than or equal to the threshold, the delay, power, Doppler, and angle information corresponding to that path are reported. For example, in a sensing system, there are two sensing targets (a human-shaped sensing target shown in Figure 3A). The number of sensing transmit beams is M=4, the number of sensing receive beams is N=3, the number of optimal sensing transmit / receive beam pairs is K=3, and the number of strongest paths is P=1. The first device determines the optimal sensing beam pair and corresponding path information based on measurements and reports it to the second device. For example, the reported information, i.e., the sensing information, is {Tx#1,Rx#1,delay#1,power#1,doppler#1,AOD#1,AOA#1}, {Tx#3,Rx#2,delay#2,power#2,doppler#2,AOD#2,AOA#2}, {Tx#3,Rx#3,delay#3,power#3,doppler#3,AOD#3,AOA#3}. After the second device acquires the sensing information, when it switches to sensing in the opposite direction to the aforementioned sensing direction, that is, the first device transmits the sensing signal through the sensing transmit beam, and the second device receives the sensing signal through the sensing receive beam. The first device can select an appropriate sensing transmit beam based on the information configured in the second device. For example, when the first device cannot determine the sensing transmit beam based on the beam correspondence assumption, the first device needs to redetermine the sensing transmit beam through beam scanning. Similarly, the second device needs to redetermine the sensing receive beam through beam scanning. In this case, the first device can directly determine the sensing transmit beam pair with the second device through the optimal transmit / receive beam pair configured in the second device and the associated path information, or it can traverse and determine the sensing transmit / receive beam pair in the configured optimal transmit / receive beam pair set. For example, Rx#1 can be used as the sensing transmit beam for sensing target 1, and Tx#1 can be used as the sensing receive beam for sensing target 1.

[0270] For example, as shown in Figure 3B, the second device repeatedly transmits sensing signals through the same sensing transmit beam, and the first device receives the sensing signals through N sensing receive beams respectively. The number K of the optimal sensing receive beam pairs can be configured by the network, predefined by the protocol, or determined based on the measurement results of the first device and the power threshold preset by the protocol. The first device determines the optimal K sensing receive beams {n1,n2,…,nK} based on the metric values ​​of the sensing measurements, and measures and obtains the time delay, power, Doppler, angle, etc., corresponding to the strongest P paths contained in each sensing receive beam. For example, the reported path is determined based on the power threshold configured by the network side or other nodes or the power threshold predefined by the protocol. When the power of the path is greater than or equal to the threshold, the time delay, power, Doppler, and angle information corresponding to the path are reported. For example, as shown in Figure 3B, there is one sensing target in the sensing system, the sensing transmit beam is fixed, the number of sensing receive beams is N=3, the optimal number of sensing receive beams is K=2, and the number of the strongest paths is P=1. The first device determines the optimal sensing beam pair and corresponding path information based on measurements and reports it to the second device. For example, the reported information, i.e., the sensing information, is {Rx#1,delay#1,power#1,doppler#1,AOD#1,AOA#1}, {Rx#2,delay#2,power#2,doppler#2,AOD#2,AOA#2}. After obtaining the relevant information, when the second device switches to sensing in the opposite direction, i.e., the first device transmits the sensing signal through the sensing transmit beam, and the second device receives the sensing signal through the sensing receive beam, the first device can select an appropriate sensing transmit beam according to the information configured in the second device, and the second device can select an appropriate sensing receive beam independently. For example, Rx#1 can be used as the sensing transmit beam for sensing target 1, and Tx#1 can be used as the sensing receive beam for sensing target 1.

[0373] The sensing receiver displays the reported sensing information to a functional node, which may be a sensing function entity, etc., and the sensing information may be one or more of the following:

[0374] The sensing information is the sensing transmit beam ID corresponding to the largest one or more sensing measurement values;

[0375] The sensing information is a pair of sensing transmit beam IDs consisting of the sensing transmit beam ID and the sensing receive beam ID corresponding to the largest one or more sensing measurement values.

[0376] Optionally, the sensing transmit beam ID may be information such as the sensing reference signal ID;

[0377] Optionally, the sensing and receiving beam ID can be defined spatial receiving filter information related ID, etc.

[0378] The sensing information is the channel information of one or more paths associated with each sensing receive beam ID or sensing transmit / receive beam ID pair.

[0379] The channel information of the path can be one or more of the following: time delay, power, angle, etc. The angle information can be one or more of AOD, ZOD, AOA, ZOA;

[0380] Optionally, the selection of the path can be determined by a power threshold through protocol predefinition or network configuration to select the path information associated with the path that needs to be reported. Alternatively, other measurement values ​​can also be used to select the path information associated with the path that needs to be reported.

[0381] The number of the optimal sensing transmit beam, sensing receive beam, and sensing transmit / receive beam pairs reported can be predefined by network configuration or protocol, such as through RRC configuration.

[0382] Optionally, the sensing metric may be the power of each path, the time-delay-Doppler peak energy calculated based on algorithms such as 2D-DFT, the time-delay / Doppler / angle spectrum peak energy calculated based on algorithms such as MUSIC / ESPRIT, and other measurement metrics used to measure the energy of the received signal of the sensing reference signal.

[0383] Optionally, the sensing function node can be configured with auxiliary information to configure the beam scanning operation of the sensing receiver. For example, the sensing function node can be configured with the angular range, time delay range, and / or Doppler frequency range where the sensing target may be located, so that the beam scanning process of the sensing receiver only needs to detect possible paths passing through the sensing target within the configured angle, time delay, and Doppler frequency range. For example, based on the configured angular range, the sensing receiver may be able to reduce the number of receiving beams that need to be scanned. Accordingly, the metric is a measure of the path detected within the configured angle, time delay, and Doppler frequency range. Using such auxiliary information can reduce the processing complexity of the sensing receiver. When the auxiliary information is unavailable, the sensing receiver needs to scan more receiving beams and detect possible paths passing through the sensing target within a larger time delay and Doppler frequency range.

[0384] In an exemplary embodiment, as shown in Figure 3A, for example, in determining downlink sensing wide beam pairs, the BS transmits M different sensing reference signals through M different sensing transmit beams, corresponding to sensing reference signal IDs or sensing transmit beam IDs {1,…,M}, respectively. The UE receives the aforementioned sensing reference signals through N sensing receive beams. The optimal number of sensing receive beam pairs K can be configured by the network, predefined by the protocol, or determined based on the UE's measurement results and a power threshold pre-set by the protocol. The UE determines the optimal K sensing transmit / receive beam pairs IDs {m1-n1,m2-n2,…,mK-nK} based on sensing measurement values, and measures and obtains the delay, power, Doppler, angle, etc., corresponding to the strongest P-path contained in each sensing transmit / receive beam pair. For example, the reported path is determined based on the power threshold configured by the network side or other nodes or the power threshold pre-defined by the protocol. When the power of the path is greater than or equal to the threshold, the delay, power, Doppler, and angle information corresponding to that path are reported. For example, in a sensing system, there are two sensing targets, with M=4 sensing transmit beams, N=3 sensing receive beams, K=3 optimal sensing transmit / receive beam pairs, and P=1 strongest path. The UE determines the optimal sensing beam pair and corresponding path information based on measurements and reports it to the sensing function entity. For example, the reported information might be {Tx#1,Rx#1,delay#1,power#1,doppler#1,AOD#1,AOA#1}, {Tx#3,Rx#2,delay#2,power#2,doppler#2,AOD#2,AOA#2}, or {Tx#3,Rx#3,delay#3,power#3,doppler#3,AOD#3,AOA#3}. After obtaining the relevant information, when switching to uplink sensing, the UE can select the appropriate sensing transmit beam based on the information configured by the sensing function node. For example, when the UE cannot determine the sensing transmit beam based on the beam correspondence assumption, the UE needs to redetermine the sensing transmit beam through beam scanning. Similarly, the BS also needs to redetermine the sensing receive beam through beam scanning. At this time, the BS and UE can directly determine the sensing transmit beam pair through the optimal transmit and receive beam pair configured in the sensing function node and the associated path information, or traverse and determine the sensing transmit and receive beam pair in the configured optimal transmit and receive beam pair set. For example, Rx#1 can be used as the transmit beam of sensing target 1, and Tx#1 can be used as the receive beam of sensing target 1.

[0385] In an exemplary embodiment, as shown in Figure 3B, during the determination of the downlink sensing narrow receiving beam, the BS repeatedly transmits sensing reference signals through the same sensing transmit beam, and the UE receives the aforementioned sensing reference signals through N sensing receive beams respectively. The number K of the optimal sensing receive beam pairs can be configured by the network, predefined by the protocol, or determined based on the UE's measurement results and a power threshold pre-set by the protocol. The UE determines the optimal K sensing receive beams {n1,n2,…,nK} based on the sensing measurement values, and measures and obtains the delay, power, Doppler, angle, etc., corresponding to the strongest P paths contained in each sensing receive beam. For example, the reported path is determined based on the power threshold configured by the network side or other nodes or the power threshold pre-defined by the protocol. When the power of the path is greater than or equal to the threshold, the delay, power, Doppler, and angle information corresponding to the path are reported. For example, in a sensing system, there is one sensing target, the sensing transmit beam is fixed, the number of sensing receive beams is N=3, the optimal number of sensing receive beams is K=2, and the number of the strongest paths is P=1. The UE determines the optimal sensing beam pair and corresponding path information based on measurements and reports it to the sensing function entity. For example, the reported information is {Rx#1,delay#1,power#1,doppler#1,AOD#1,AOA#1}, {Rx#2,delay#2,power#2,doppler#2,AOD#2,AOA#2}. After the sensing function node obtains the relevant information, when switching to uplink sensing, the UE can select the appropriate sensing transmission beam according to the information configured by the sensing function node. For example, Rx#1 can be used as the transmission beam for sensing target 1, and Tx#1 can be used as the reception beam for sensing target 1.

[0386] This disclosure proposes a beam reporting scheme in a sensing system. Based on the framework of reporting sensing transmit beams and sensing measurements, it displays and reports sensing receive beams, thereby reducing the beam scanning complexity when the sensing receiver acts as a sensing transmitter.

[0387] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0388] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. 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. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. 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).
