Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a communication sensing signal processing method and device. Background Technology

[0002] The integrated design of communication and sensing modules combines communication and sensing modules, enabling the sensing of the communication environment within a cellular communication system. Sensing, the detection of the physical world, exhibits diverse characteristics such as accuracy, recognition speed, and resolution. For example, radar equipment can perform environmental detection and sensing, including target detection or scene imaging; while communication systems primarily handle point-to-point information or data transmission.

[0003] Integrated communication and sensing can optimize spectrum utilization and the efficiency of hardware and software devices. For example, radar signals and communication signals can share the same spectrum resources through time-division, frequency-division, or space-division multiplexing. Furthermore, without affecting communication functions, signals in a communication system can also achieve adaptive sensing of targets or the environment, assisting in processes such as channel parameter acquisition, environmental information acquisition for communication link design, beam velocity alignment, and CSI acquisition. For example, reference signals in a communication network can be used as sensing signals.

[0004] In future communication systems, the diversity and multi-level characteristics of terminal devices will be more pronounced, with different levels of terminal devices possessing varying processing capabilities. In integrated communication and sensing systems, radar signals and communication signals can share physical resources across different dimensions such as time, frequency, and space. The processing capabilities of terminal devices (including receiving signal processing capabilities and transmitting signal processing capabilities) are also shared between the two types of signals. Due to limitations in processing capabilities, at specific times, terminal devices may not be able to simultaneously process sensing system or communication information. Furthermore, under conditions of limited transmission power, terminal devices may also be unable to simultaneously transmit communication information and sensing signals. Summary of the Invention

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] This application addresses the allocation of device processing power between communication and sensing in an integrated communication and sensing system, aiming to optimize the efficiency of the integrated system. The solution is conceived as follows: by configuring information indicators or pre-setting the priority of downlink information processing / uplink information processing / uplink power allocation, including: the processing priority order between radar information and communication information, whether sensing signals need to be processed, the priority order between signals used for sensing and signals used for communication in the communication information, and the priority order of the same signals according to their functions.

[0056] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0057] Figure 1 This is a flowchart illustrating an embodiment of the method of this application.

[0058] This application provides a communication sensing signal processing method, including the following steps:

[0059] Step 101: Determine a first set of signals for shared physical resources, wherein the first set of signals includes sensing signals.

[0060] In any embodiment of this application, the sensing signal includes at least one of the following signals: radar signal, downlink reference signal in a new air communication system, and uplink SRS signal.

[0061] The shared physical resources described in this application refer to the time-frequency domain resources of a shared communication channel or shared hardware devices. For example, multiple signals in a first signal set may overlap in time. Another example is the use of the same processor resources. The amount of physical resources in this application can be represented by duration, bandwidth, and storage space, or by the capabilities of the hardware devices, such as total power and maximum speed.

[0062] Step 102: Determine the priority of the sensing signal based on the first indication information.

[0063] The priority of the sensing signal includes the priority among multiple sensing signals and the priority between the sensing signal and the communication signal. When there is a priority among multiple sensing signals, in one embodiment of this application, the first indication information is further used to indicate whether the sensing signal is processed, that is, the sensing signal with higher priority is processed, and the sensing signal with lower priority is not processed.

[0064] Preferably, the first signal set includes communication signals; the first indication information is also used to determine the priority of the communication signals.

[0065] In any embodiment of this application, the first indication information is higher-layer signaling, physical-layer signaling, or a preset one.

[0066] Step 103: Determine the amount of physical resources occupied by a single signal in the second signal set based on the second instruction information.

[0067] As an optional step, the minimum amount of resources required for a signal can be identified by the second indication information.

[0068] In any embodiment of this application, the second indication information is higher-layer signaling, physical-layer signaling, or a preset one.

[0069] Step 104: Determine a second set of signals that satisfies the first indication information. The second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance.

[0070] In step 104, a second set of signals is determined to be processed within the first set of signals according to their respective priority levels. The second set of signals is a subset of the first set of signals; the priority of the second set of signals is higher than the priority of other signals in the first set of signals. Processing the second set of signals does not exceed the processing capacity of the device, or transmitting the second set of signals does not exceed the maximum transmission power of the device. It should be noted that the second set of signals being a subset of the first set of signals includes the second set of signals being a proper subset of the first set of signals, or the second set of signals being equal to the first set of signals.

[0071] Figure 2 This is a flowchart illustrating an embodiment of the method of this application used by a terminal device to receive a first set of signals.

[0072] Step 201A: The terminal device determines a first set of signals for sharing physical resources. The first set of signals is a downlink signal, which includes sensing signals.

[0073] For example, including the following situations:

[0074] The shared physical resource is a shared processor, and the physical resource tolerance is the processor capacity;

[0075] The shared physical resources are time-domain or frequency-domain channel resources, and the physical resource tolerance is the channel capacity.

[0076] Step 202A: The terminal device determines the priority of the sensing signal according to the first indication information;

[0077] Step 203A: The terminal device determines and receives a second set of signals that satisfies the first indication information. The second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance.

[0078] More preferably, feedback information is sent to the second set of signals. For example, this could involve measuring the sensed signals in the second set of signals and providing feedback information indicating the measurement results.

[0079] For example, the shared physical resource is a shared processor, and the physical resource tolerance is the processor capacity. Downlink reference signals in the NR system include Channel State Information Reference Signal (CSI-RS). The general workflow of CSI-RS is: the base station sends CSI-RS, the terminal device (UE) measures the CSI-RS, and reports the CSI feedback results. Furthermore, CSI-RS can also be used for mobility management measurements, beam management measurements, etc. CSI-RS configurations are divided into periodic CSI-RS, semi-persistent CSI-RS, and aperiodic CSI-RS. Based on the configured CSI-RS, the CSI reported by the UE accordingly includes periodic CSI, semi-persistent CSI, and aperiodic CSI. The UE's ability to process CSI simultaneously is limited; therefore, it is necessary to determine which CSIs the UE processes according to certain processing rules. Assume N... CPU For a UE to report CSIs simultaneously, if L CPUs are already used to calculate the CSI report within a certain OFDM symbol, then the number of remaining unused CPUs is N. CPU -L. At this point, N CSI reports begin to occupy the corresponding CPU resources on the same symbol. Ultimately, M CSI reports are updated, and NM CSI reports are not updated, where 0 ≤ M ≤ N. The number of CPUs occupied by each of the N CSI reports is... The final result of M satisfies the formula The maximum value, 0≤M≤N. These M CSIs are the M highest priority CSIs among the N CSIs. The priority of CSI reports is related to the type of CSI (periodic CSI, semi-persistent CSI, or aperiodic CSI), content (whether the CSI reports L1-RSRP), and index (the cell index for which the CSI report is made, and the index of the CSI report).

[0080] Currently, CSI-RS can be used for channel measurement, time-frequency synchronization, beam management measurement, and mobility management measurement. If the priority order of CSI-RS to be processed is determined solely based on whether the CSI report is periodic, aperiodic, or semi-persistent, and whether the CSI report includes beam measurements based on CSI-RS, the terminal device's processing of CSI-RS cannot meet the quality of service requirements of an integrated sensing system. In an integrated sensing system, if CSI-RS is configured as a sensing signal, and the UE's CSI processing capability is limited, it is necessary to determine the priority order between the terminal device processing this sensing signal and processing other CSI-RS to meet different levels of sensing requirements.

[0081] Using the scheme of this application, if CSI-RS is used as a sensing signal, the priority level of the sensing signal can be configured simultaneously. For example, the priority level of the sensing signal can be configured to be higher than, equal to, or lower than other CSI-RS. Alternatively, the priority level relationship between the sensing signal and various types of CSI-RS can be configured. For example, the priority level relationship with any CSI-RS used for channel measurement, time-frequency synchronization, beam management measurement, or mobility management measurement. Alternatively, considering whether the CSI report is periodic, aperiodic, or semi-persistent, and various combinations of CSI-RS used for channel measurement, time-frequency synchronization, beam management measurement, and mobility management measurement, when the UE's processing capacity is limited, the priority level of the sensing signal determines which CSI-RS to process. For example, if the first indication information identifies the level of the first type of sensing signal as 2, and the level of other CSI-RS in the first signal set is 3, then when the UE's CSI processing capacity is limited, the UE will prioritize processing the first type of sensing signal.

[0082] Optionally, the CSI-RS signals used for sensing functions can be further divided into multiple levels, and the priority order between each level of CSI-RS sensing signals and other signals can be different. For example, CSI-RS sensing signals used for emergency services have a higher priority level than other CSI-RS signals, while CSI-RS sensing signals used for general services have a lower priority level than other CSI-RS signals.

[0083] Figure 3 A schematic diagram illustrating an embodiment of a terminal device receiving frequency division signals.

[0084] When the first signal set is a downlink signal, for example, the shared physical resource is a time-domain or frequency-domain channel resource, and the physical resource tolerance is the channel capacity.

[0085] Communication information and sensing signals may reuse wireless resources through frequency division, such as Figure 3 As shown, the communication information and sensing signal frequency division acquired by the terminal device.

[0086] If the communication information and sensing signals acquired by the terminal device are frequency-divided, but the terminal device shares a processor for processing the received communication information and sensing signals, then how the terminal device determines which part of its processor should be used for communication information and which part for sensing signal processing, given the terminal device's limited processing power, will affect the efficiency of the integrated sensing system. Here, the sensing signal refers to the signal used for sensing in the communication system.

[0087] Optionally, the sensing signal is a radar signal; further, the radar signal is a first type of sensing signal. The first signal set includes communication information, and the first indication information is used to determine the relationship between the level of the first type of sensing signal and the communication information. The first indication information is indicated by configuration information or pre-configured by the system.

[0088] If the communication information and sensing signals acquired by the terminal device are frequency-divided, and the terminal device shares a processor for the received communication information and sensing signals, the terminal device determines whether to prioritize processing the radar signal or the communication information based on the first indication information. Even when the terminal device's processing capacity is limited, this ensures that the processed signal or information contributes to the overall efficiency of the system and guarantees the quality of service.

[0089] Figures 4(a) and (b) are schematic diagrams of embodiments of terminal device distinguishing sensing signal processing, wherein Figure 4(a) is passive echo and Figure 4(b) is sensing feedback. In this embodiment, when the first signal set is a downlink signal, and when there is a priority among multiple sensing signals, in one embodiment of this application, the first indication information is further used to indicate whether the sensing signals are processed, that is, the sensing signals with higher priority are processed, and the sensing signals with lower priority are not processed.

[0090] In one scenario of integrated communication and sensing deployment, the first device sends a sensing signal and acquires environmental information by detecting the echo reflected from the second device, as shown in Figure (a). In this case, the second device does not need to process the sensing signal. In another scenario, the first device sends a sensing signal, and the second device feeds back the acquired and detected sensing signal features to the first device, as shown in Figure (b). In this case, the second device needs to process the sensing signal.

[0091] Currently, in the design of integrated sensing systems, the second device does not distinguish between the processing methods of sensing signals in two different situations. This leads to an inefficient allocation of the terminal device's processing power and transmission power between the sensing signal and other signals, affecting system efficiency. In this embodiment, optionally, the sensing signal is a radar signal, or the sensing signal is a signal used for sensing in the communication system.

[0092] Optionally, if the first indication information identifies the level of the sensed signal as Level 1, the device is instructed not to process the sensed signal. If the first indication information identifies the level of the sensed signal as Level 2, the device is instructed to process the sensed signal. Optionally, the sensed signal is a downlink reference signal or a radar signal in a new air interface communication system.

[0093] In this embodiment, the terminal device determines the second signal set according to the first indication information. That is, when the level of the sensing signal identified by the first indication information is the second level, it is determined to be the second signal set, and feedback to the second signal set is generated, which is information representing the sensing result.

[0094] In this embodiment, the first indication information is used to determine whether the device needs to process the sensing signal, and whether the processing method for the sensing signal is a self-transmitting and self-receiving method or a method where the device feeds back the characteristics of the sensing signal. The receiving and transmitting devices of the integrated sensing system have a consistent method for determining the sensing signals and communication information processed by the terminal device, or the transmission power of the sensing signals and communication information. This ensures that the terminal device can reasonably allocate its processing capabilities and transmission power among the sensing signals and other signals, thus guaranteeing system efficiency.

[0095] Figure 5 This is a flowchart illustrating an embodiment of the method of this application used by a terminal device to transmit a second set of signals.

[0096] Step 201B: The terminal device determines a first set of signals for shared physical resources. The first set of signals includes sensing signals and is either an uplink signal or a sidelink transmission signal.

[0097] For example,

[0098] The shared physical resource is a shared processor, and the physical resource tolerance is the processor capacity;

[0099] The shared physical resources are time-domain or frequency-domain channel resources, and the physical resource tolerance is the channel capacity;

[0100] The shared physical resource is a shared transmitter, and the physical resource tolerance is the total transmission power.

[0101] Step 202B: The terminal device determines the priority of the sensing signal according to the first indication information;

[0102] Step 203B: The terminal device determines the amount of physical resources occupied by a single signal in the second signal set according to the second instruction information.

[0103] Step 204B: The terminal device determines and sends a second set of signals that satisfies the first indication information. The second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance.

[0104] For example, the shared physical resource is a time-domain or frequency-domain channel resource, the physical resource tolerance includes channel capacity, and the shared physical resource is a shared transmitter, the physical resource tolerance also includes total transmission power.

[0105] In existing NR system designs, if a terminal device needs to transmit simultaneously on two or more channels with overlapping time resources, and the sum of the transmission power of these channels exceeds the maximum transmission power of the terminal device, the terminal device will allocate the transmission power to the higher-priority signal according to a preset priority order. The preset channel priority order, from highest to lowest, includes:

[0106] PRACH on PCell has the highest priority.

[0107] Secondly, their priority is determined according to the priority level of PUCCH / PUSCH. The higher the priority of PUCCH / PUSCH, the higher the priority in power allocation.

[0108] For PUCCH / PUSCH of the same priority level, PUCCH carrying HARQ-ACK, SRS, LRR or PUSCH carrying HARQ-ACK has the highest priority, followed by PUCCH or PUSCH carrying CSI, and finally PUSCH without HARQ-ACK or CSI and PUSCH on Pcell in the 2-step RACH process.

[0109] SRS transmission, where non-periodic SRS has higher priority than semi-persistent SRS and / or periodic SRS, or PRACH on cells other than PCell. Currently, SRS in NR systems performs functions including channel measurement, beam management, and antenna switching.

[0110] Therefore, according to existing technology, if a terminal device needs to transmit simultaneously on two or more channels with overlapping time resources, and the sum of the transmission power of these channels exceeds the maximum transmission power of the terminal device, the SRS has the lowest priority among the priority order of the channels.

[0111] In a sensing-integrated system, if the SRS is configured as a sensing signal, and the UE's transmit power is limited, it is necessary to determine the priority order of the terminal device in processing the sensing signal and processing other uplink channels to meet different levels of sensing requirements.

[0112] By adopting the technical solution of this application, if the SRS is used as a sensing signal, the priority relationship between the sensing signal and other uplink channels transmitted simultaneously can be configured to ensure the effective transmission of the sensing signal.

[0113] If the SRS is used as a sensing signal, which may serve urgent or high-quality services, the position of the SRS signal used for sensing function in the current channel priority order is configured through the first information, and the transmission power between the sensing signal and the communication information is reasonably allocated. Therefore, the priority of the SRS signal is related to the function it undertakes, rather than just to whether the SRS is aperiodic, semi-persistent, or periodic.

[0114] Optionally, the SRS signals used for sensing functions can be further divided into multiple levels, and the priority order between each level of SRS sensing signal and other signals can be different. Their priority is identified by a first indication information; for example, an SRS sensing signal used for emergency services has a higher priority level than a PUCCH / PUSCH carrying HARQ-ACK, while an SRS sensing signal used for general services has a lower priority level than a PUCCH / PUSCH carrying HARQ-ACK.

[0115] Figure 6 A schematic diagram of an embodiment for transmitting frequency division signals to terminal devices.

[0116] The first signal set is an uplink signal or a sidelink transmission signal. The communication signals and sensing signals sent by the terminal device are frequency-divided, and the communication information and sensing signals may reuse wireless resources through frequency division.

[0117] The terminal device shares a processor for processing the transmitted communication information and sensing signals. When the processing power of the terminal device is limited, how the terminal device determines whether to use the processor for communication information and sensing signal processing will affect the efficiency of the integrated sensing system.

[0118] If the communication information and sensing signals transmitted by the terminal device are frequency-divided, and the terminal device's transmission power is limited, how the terminal device determines which transmission power to use for communication information and which for sensing signal processing will affect the efficiency of the integrated sensing system. Optionally, the sensing signal can be a radar signal, or a signal used for sensing in the communication system.

[0119] By adopting the technical solution of this application, if the communication information and sensing signal transmitted by the terminal device are frequency-divided, and the transmission power of the terminal device is limited, the terminal device can determine whether to prioritize processing radar signals or communication information based on the first indication information, which can ensure that the processed signals or information are beneficial to the overall efficiency of the system and guarantee the service quality of the device.

[0120] Optionally, the terminal device can also acquire second indication information to determine the minimum transmission power of any item of radar signal and communication information. When the transmission power of the terminal device is limited, the terminal device, based on ensuring the minimum transmission power of each radar signal and / or communication information, determines which signal to allocate the remaining transmission power in the maximum transmission power of the device according to the priority level relationship of radar signal and communication information. This ensures the basic service performance of radar signal and / or communication information and optimizes the signal or information being processed, which is beneficial to the overall efficiency of the system and ensures the service quality of the device.

[0121] Figure 7 This is a flowchart of an embodiment of the method of this application used by a network device to obtain the processing result of a second set of signals.

[0122] As a further optimized technical solution, when the network device can know in advance the processing capacity (i.e., physical resource tolerance) of the terminal device, it can determine to send only the second signal set when there is a need to send the first signal set, thereby improving system efficiency. Alternatively, when the network device can know in advance the processing capacity (i.e., physical resource tolerance) of the terminal device, when there is a need to send the first signal set, the network device does not expect the terminal device to process all of the first signal set, but instead obtains the processing result of the terminal device on the second signal set.

[0123] Step 301A: The network device determines a first set of signals for shared physical resources, the first set of signals including sensing signals, and the first set of signals being downlink signals;

[0124] The shared physical resource is the processor of the shared terminal device, and the physical resource tolerance is the processor capacity of the terminal device; or, the shared physical resource is a time-domain or frequency-domain channel resource, and the physical resource tolerance is the channel capacity.

[0125] Step 302A: The network device determines and sends first indication information, the first indication information indicating the priority of the sensing signal and / or communication signal;

[0126] The priority of the sensing signal and / or communication signal is determined based on the first indication information;

[0127] The first indication information may be preset or obtained through higher-layer signaling; the network device may also send the first indication information to the terminal device.

[0128] Step 303A: The network device determines and sends a second set of signals that satisfies the first indication information, wherein the second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance; or, the network device sends the first set of signals and receives the processing result of the terminal device on the second set of signals, wherein the second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance.

[0129] Since the shared physical resources and physical resource tolerance in step 301A are related to the terminal device, and the second signal set in step 303A is determined based on the physical resource tolerance of the terminal device, the network device sends the second signal set to the terminal device in step 303A. Alternatively, even if the network device sends the first signal set to the terminal device, the network device does not expect to obtain the processing results of the terminal device for all the first signal sets, but rather obtains the processing results of the terminal device for the second signal set.

[0130] Figure 8 This is a flowchart illustrating an embodiment of the method of this application used by a network device to receive a second set of signals.

[0131] As a further optimized technical solution, when the network device can know in advance the processing capacity of the terminal device, i.e. the physical resource tolerance, then when there is a demand to receive the first set of signals, it can determine to only receive the second set of signals, thereby improving system efficiency.

[0132] Step 301B: The network device determines a first set of signals for shared physical resources, the first set of signals including sensing signals, and the first set of signals being uplink signals;

[0133] The shared physical resource is the processor of the shared terminal device, and the physical resource tolerance is the processor capacity of the terminal device; or, the shared physical resource is time-domain or frequency-domain channel resource, and the physical resource tolerance is the channel capacity; or, the shared physical resource is the transmitter of the shared terminal device, and the physical resource tolerance is the total transmission power of the terminal device.

[0134] Step 302B: The network device determines and sends first indication information, the first indication information indicating the priority of the sensing signal and / or communication signal;

[0135] The priority of the sensing signal and / or communication signal is determined based on the first indication information;

[0136] The first indication information may be preset or obtained through higher-layer signaling; the network device may also send the first indication information to the terminal device.

[0137] Step 303B: The network device determines and receives a second set of signals that satisfies the first indication information. The second set of signals is a subset of the first set of signals, and the amount of physical resources occupied by the second set of signals does not exceed the physical resource tolerance.

[0138] Furthermore, in Figures 7-8 In the illustrated embodiment, a second indication information may also be included, wherein the network device determines the second indication information and / or determines, based on the second indication information, the minimum amount of physical resources occupied or the minimum energy required for each signal in the second signal set.

[0139] Furthermore, in Figures 7-8 In this embodiment, to enable network devices to know in advance the shared physical resources and tolerances of terminal devices, this can be obtained through terminal device reporting or through system-preset standard values. When reporting through terminal devices, the reported value can be taken from a specific terminal device, or a typical value of a class of terminal devices can be used as the value for a specific terminal device.
