[0001] This disclosure claims priority to Chinese Patent Application No. 202510062573.5, filed with the Chinese Patent Office on January 15, 2025, entitled "Sensing Processing Method, Apparatus and Communication Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a sensing processing method, apparatus and communication equipment. Background Technology

[0003] In current research on Integrated Sensing and Communications (ISAC), the reuse of Positioning Reference Signals (PRS) as sensing signals is frequently mentioned. However, according to current standards, using multiplexed PRS as sensing signals for ISAC velocity measurement has significant limitations. In most PRS configurations, the time intervals between adjacent PRS cannot be kept constant. Only a very few configurations, such as transmitting a PRS only in one symbol within each PRS transmission slot on a subcarrier, can achieve a uniform distribution of the sensing signal in the time domain. This limitation makes using multiplexed PRS as an ISAC reference signal very inflexible, and in this configuration, the PRS time-domain density is very sparse, the time intervals between PRS are too long, and the velocity sensing performance is limited.

In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this disclosure. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0073] It should be understood that the phrase "an embodiment" or "one embodiment" throughout the specification means that a particular feature, structure, or characteristic relating to an embodiment is included in at least one embodiment of this disclosure. Therefore, "in one embodiment" or "one embodiment" appearing throughout the specification does not necessarily refer to the same embodiment.

[0074] In the various embodiments of this disclosure, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this disclosure.

For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0076] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0077] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0078] The embodiments of this disclosure provide a sensing processing method, apparatus, terminal, and network-side device to solve the problem of affecting sensing performance when multiplexing communication signals as sensing signals.

[0079] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0080] As shown in Figure 1, an embodiment of this disclosure provides a perception processing method applied to a perception execution node. The method specifically includes the following steps:

[0081] Step 101: The perception execution node receives the perception parameter configuration information sent by the perception function node;

[0082] Step 102: The perception execution node executes the perception task according to the perception parameter configuration information and the BWP configuration information;

[0083] Perception refers to the detection of parameters of objects in the environment by the perception execution node, such as detecting the speed and position of objects.

[0084] The sensing parameter configuration information includes at least one of the following:

[0085] (1) The first parameter is used to determine the temporal density of the sensed signal; this first parameter can be expressed as: The time-domain density of the sensing signal is used to determine the maximum sensing range. The time-domain density of the sensing signal refers to the symbol sparsity (comb size) of the sensing signal (SS) in the time domain, such as the sensing signal being transmitted once every X time-domain symbols.

[0086] First parameter This first parameter can be represented as the symbol sparsity (comb size) of the sensing signal (SS) in the time domain. For example: This means that a sensing signal is sent every four symbols in the time domain. The smaller the size, the larger the range of perception.

[0087] (2) The sensing signal slot group (SS slot group) is a time-domain resource unit for sensing signals. The sensing signal slot group is based on the first parameter. The numerical value determines the smallest time unit for configuring sensing signals. This can also be understood as configuring the time-domain resources of sensing signals at the granularity of sensing signal time slot groups. For example, configuring the time-domain resources of sensing signals as Y SS slot groups. When SS slot groups with the same configuration are consecutive, the sensing signals transmitted on consecutive SS slot groups can be guaranteed to be uniformly distributed.

[0088] Each SS slot group contains one or more time slots. When configuring the time domain resources of sensing signals, the sensing function nodes use SS slot groups as the basic unit for configuration.

[0089] (3) The second parameter is used to determine the symbol position of the first sensing signal in each sensing signal time slot group; the second parameter can be expressed as: This parameter can indicate the symbol position of the first sensing signal in each SS slot group, for example, indicating the symbol number (or symbol index) of the first sensing signal. This second parameter allows for more flexible configuration of sensing signal transmission.

[0090] (4) The number of time slot groups configured for sensing signals. This can also be understood as the number of SS slot groups configured, or the number of SS slot groups used to transmit sensing signals. The number of time slot groups configured for sensing signals is a positive integer greater than or equal to 1. The number of time slot groups configured for sensing signals determines the duration of the sensing signal, and thus the speed measurement resolution and accuracy. For example: if the required sensing duration is 10ms based on the sensing requirements, and the length of a sensing signal time slot group is 1ms, then the number of sensing signal time slot groups that need to be configured is 10.

[0091] In some embodiments, the sensing execution node includes a terminal and / or a network-side device; the BWP configuration information is configured by the network-side device. In this embodiment, the sensing execution node is a device that performs sensing tasks, which can be a terminal or a network-side device, such as a base station. Performing sensing tasks may include sending sensing signals, receiving sensing signals, and performing sensing measurements. For example, the base station sends sensing signals, the terminal receives sensing signals and sends echo signals back to the base station; the operations performed by both the base station and the terminal can be considered as performing sensing tasks.

[0092] In some embodiments, the Sensing Function (SF) node is an independent node; or, the Sensing Function node is deployed on at least one of the following devices: a terminal, a base station, or a core network device. In this embodiment, the Sensing Function node may have the capability to configure sensing information and may be deployed on a terminal or network-side device, or it may be an independent device. The Sensing Function node can determine sensing parameter configuration information based on sensing requirements, such as one or more of the following: speed measurement resolution, speed measurement accuracy, and sensing requirement location. The sensing parameter configuration information may be configuration information of parameters related to the sensing signal. The Sensing Function node can also select a suitable sensing execution node (terminal and / or base station) based on the sensing requirements and send the sensing parameter configuration information to the sensing execution node.

[0093] BWP configuration information can be information about the BWP used to perform sensing tasks, and can be configured by network-side devices. For example, assuming the sensing execution node is a terminal, the network-side device (such as a base station) configures the BWP configuration information for the terminal; if the sensing execution node is a base station, the base station can determine the BWP configuration information.

[0094] The sensing execution node performs sensing tasks on the BWP configured in the BWP configuration information according to the sensing parameter configuration information, such as sending sensing signals, receiving sensing signals, and performing sensing measurements such as velocity and position of objects. The sensing signals corresponding to the sensing parameter configuration information are uniformly distributed in the time domain, which can ensure the applicability of multiplexed communication signals (such as PRS) as sensing signals, increase the configuration flexibility of communication signals (such as PRS), and provide important technical support for the integration of sensing and communication.

[0095] In the embodiments of this disclosure, the sensing function node is configured with sensing parameter configuration information, and the sensing execution node executes the sensing task according to the sensing parameter configuration information and BWP configuration information, which can ensure that the sensing signal is evenly distributed, meet the requirements of high-precision speed measurement and sensing, and improve the speed measurement performance of ISAC.

[0096] As an optional embodiment, the number of time slots included in the sensing signal time slot group is determined according to the time domain density of the sensing signal;

[0097] When there are at least two sensing signal time slot groups, the sensing signals are uniformly distributed in at least two consecutive sensing signal time slot groups.

[0098] In this embodiment, the number of time slots included in the sensing signal slot group (SS slot group) is determined based on the temporal density of the sensing signal (or a first parameter). Based on the temporal density of the sensing signal, it is necessary to ensure that the sensing signal is uniformly distributed in multiple consecutive sensing signal time slot groups.

[0099] The number of time slots contained in a time slot group may vary depending on the temporal density of the sensing signal. Based on the number of time slots contained in a time slot group, the time slot group of the sensing signal can be defined as a variety of types (SS slot group type).

[0100] For example: SS slot group type 1: Each SS slot group contains 1 time slot. When using SS slot group type 1,

[0101] For example, if the time-domain density comb size of the sensing signal is 2, meaning one sensing signal is sent for every two symbols; and one time slot contains 14 symbols, then 2 is divisible by 14 (14 mod 2 = 0). Consecutive time slots with the same sensing signal configuration can achieve a uniform distribution of the sensing signal, so a sensing signal time slot group can contain only one time slot. Similarly, this also applies to comb sizes of 7 and 14, as 7 and 14 are also divisible by 14. That is, when the comb sizes are 2, 7, and 14, a sensing signal time slot group includes one time slot. Assume the symbol number of the first sensing signal in each sensing signal time slot group is 0. Figure 2 illustrates this. The distribution of time-domain sensing signals is obtained by configuring the time-domain resources of sensing signals using SS slot group type 1.

[0102] For example: SS slot group type 2: Each SS slot group contains 2 time slots. When using SS slot group type 2,

[0103] For example, if the comb size is 4, meaning one sensing signal is sent every 4 symbols; since 4 is not divisible by 14 (14 mod 4 ≠ 0), consecutive time slots with the same sensing signal configuration cannot achieve an equally spaced distribution of the sensing signals. At least 28 symbols (i.e., 2 time slots) are needed as a group for an equally spaced distribution of the sensing signals. Therefore, when the comb size is 4, a sensing signal time slot group includes 2 time slots. As shown in Figure 3, assume the symbol number of the first sensing signal in each sensing signal time slot group is 1. Figure 3 illustrates... The distribution of time-domain sensing signals is obtained by configuring the time-domain resources of sensing signals using SS slot group type 2.

[0104] For example: SS slot group type 3: Each SS slot group contains 3 time slots. When using SS slot group type 3,

[0105] For example, if the comb size is 3, meaning one sensing signal is sent every 3 symbols, since 3 is not divisible by 14 (14 mod 3 = 2, i.e., 14 mod 3 ≠ 0), consecutive time slots with the same sensing signal configuration cannot achieve an evenly spaced distribution of the sensing signals. At least 42 symbols (i.e., 3 time slots) are needed as a group for an evenly spaced distribution of the sensing signals. Similarly, this applies to a comb size of 6. 6 is not divisible by 14 (14 mod 6 ≠ 0), requiring at least 42 symbols (i.e., 3 time slots) as a group for a uniform distribution of the sensing signals. Therefore, when the comb size is 3 or 6, a sensing signal time slot group includes 3 time slots. As shown in Figure 4, assume the symbol number of the first sensing signal in each sensing signal time slot group is 2. Figure 4 illustrates... 6. The distribution of time-domain sensing signals is obtained by configuring the time-domain resources of sensing signals using SS slot group type 3.

[0106] For example: SS slot group type 4: Each SS slot group contains 4 time slots. When using SS slot group type 4,

[0107] For example, if the comb size is 8, meaning one sensing signal is sent every 8 symbols; since 8 is not divisible by 14 (14 mod 8 ≠ 0), consecutive timing sequences with the same sensing signal configuration cannot achieve an evenly spaced distribution of the sensing signals. At least 56 symbols (i.e., 4 time slots) are needed as a group for consecutive time slots with the same sensing signal configuration to achieve an evenly spaced distribution of the sensing signals. Therefore, when the comb size is 8, a sensing signal time slot group includes 4 time slots. As shown in Figure 5, assume the symbol number of the first sensing signal in each sensing signal time slot group is 3. Figure 5 illustrates... The distribution of time-domain sensing signals is obtained by configuring the time-domain resources of sensing signals using SS slot group type 4.

[0108] For example: SS slot group type 5: Each SS slot group contains 5 time slots. When using SS slot group type 5,

[0109] For example, if the comb size is 5, meaning one sensing signal is sent every 5 symbols; 5 is not divisible by 14 (14 mod 5 ≠ 0), consecutive time slots with the same sensing signal configuration cannot achieve an evenly spaced distribution of the sensing signals. At least 60 symbols (i.e., 5 time slots) are needed as a group for an evenly spaced distribution of the sensing signals. Similarly, this also applies to the case where the comb size is 10 (14 mod 10 ≠ 0). Therefore, when the comb size is 5 or 10, a sensing signal time slot group includes 5 time slots. As shown in Figure 6, assume the symbol number of the first sensing signal in each sensing signal time slot group is 4. Figure 6 illustrates... The distribution of time-domain sensing signals is obtained by configuring the time-domain resources of sensing signals using SS slot group type 5.

[0110] For example: SS slot group type 6: Each SS slot group contains 6 time slots. When using SS slot group type 6, For example, if the comb size is 12, 12 is not divisible by 14 (14 mod 12 ≠ 0), and consecutive time slots with the same sensing signal configuration cannot achieve an equally spaced distribution of the sensing signal. At least 84 symbols (i.e., 6 time slots) are needed as a group for consecutive time slots with the same sensing signal configuration to achieve an equally spaced distribution of the sensing signal. Therefore, when the comb size is 12, a sensing signal time slot group includes 6 time slots.

[0111] For example: SS slot group type 7: Each SS slot group contains 9 time slots. When using SS slot group type 7, For example, if the comb size is 9, and 9 is not divisible by 14 (14 mod 9 ≠ 0), consecutive time slots with the same sensing signal configuration cannot achieve an equally spaced distribution of the sensing signal. At least 126 symbols (i.e., 9 time slots) are needed as a group for consecutive time slots with the same sensing signal configuration to achieve an equally spaced distribution of the sensing signal. Therefore, when the comb size is 9, a sensing signal time slot group includes 9 time slots.

[0112] For example: SS slot group type 8: Each SS slot group contains 11 time slots. When using SS slot group type 8, For example, if the comb size is 11, 11 is not divisible by 14 (14 mod 11 ≠ 0), and consecutive time slots with the same sensing signal configuration cannot achieve an equally spaced distribution of the sensing signal. It is necessary to group them into groups of at least 154 symbols (i.e., 11 time slots) to achieve an equally spaced distribution of the sensing signal. Therefore, when the comb size is 11, a sensing signal time slot group includes 11 time slots.

[0113] For example: SS slot group type 9: Each SS slot group contains 13 time slots. When using SS slot group type 9, For example, if the comb size is 13, 13 is not divisible by 14 (14 mod 13 ≠ 0), and consecutive time slots with the same sensing signal configuration cannot achieve an equally spaced distribution of the sensing signal. It is necessary to group them into groups of at least 182 symbols (i.e., 13 time slots) to achieve an equally spaced distribution of the sensing signal. Therefore, when the comb size is 13, a sensing signal time slot group includes 13 time slots.

[0114] The schematic diagrams of SS slot group type 6 to SS slot group type 9 are similar to those in Figures 2 to 6 above, and will not be described again here.

[0115] As can be seen from Figures 2 to 6, through the design of the embodiments of this disclosure, using SS slot groups as the basic unit for configuring sensing signals and making the SS slot groups continuously distributed in the time domain, the interval between the last sensing signal in the previous SS slot group and the first sensing signal in the next SS slot group can still be maintained at adjacent SS slot groups. This ensures that the configured sensing signals are uniformly distributed in the time domain.

[0116] Based on the above sensing parameter configuration information, the sequence number l of all sensing signals transmitted in an SS slot group is determined as follows:

[0117] It should be noted that the symbols in the time slots are encoded starting from 0: 0, 1, 2, 3... 12, 13, with each time slot containing 14 symbols from 0 to 13.

[0118] It should be noted that the embodiments disclosed herein can be applied to a dual-base sensing mode, which refers to a mode where the location of the device sending the sensing signal and the location of the device receiving the sensing signal are different. For example, the base station sends the sensing signal and the terminal receives the sensing signal, or the terminal sends the sensing signal and the base station receives the sensing signal. In a 6G ISAC system, the device performing the sensing signal reception can simultaneously receive communication data. Therefore, the base station needs to configure BWP configuration information for the user equipment (UE) (or terminal) performing the sensing task according to the communication transmission requirements, allocate multiple BWPs, and notify the UE to use the specified BWP configuration to perform the sensing task at a specific time, in order to save time and frequency resources.

[0119] As an optional embodiment, the BWP configuration information is used to configure at least two first BWPs;

[0120] The step of performing the perception task based on the perception parameter configuration information and the BWP configuration information includes:

[0121] If the at least two first BWPs satisfy the first condition, then based on the perception parameter configuration information and the BWP configuration information, the perception task is jointly executed using the perception signals within the at least two first BWPs.

[0122] Wherein, when the at least two first BWPs satisfy the first condition, the sensing signal is uniformly distributed in the time domain within the at least two first BWPs.

[0123] In this embodiment, the sensing task is performed according to the sensing parameter configuration information and the BWP configuration information. For example, the terminal receives (or sends) sensing signals according to the sensing parameter configuration information and the BWP configuration information, and / or the base station sends (or receives) sensing signals according to the sensing parameter configuration information and the BWP configuration information.

[0124] The base station can configure BWP configuration information for the terminal and send this information to the terminal via the Physical Broadcast Channel (PBCH). When necessary, such as when the amount of communication data transmission changes, the base station can instruct the UE to perform BWP handover via Downlink Control Information (DCI) on the Physical Downlink Control Channel (PDCCH).

[0125] Only when the multiple BWPs configured in the BWP configuration information meet the first condition can the sensing execution node jointly perform sensing measurements using the sensing signals sent from the multiple BWPs.

[0126] As an optional embodiment, performing the perception task based on the perception parameter configuration information and the BWP configuration information includes:

[0127] If at least two first BWPs configured in the BWP configuration information do not meet the first condition, then:

[0128] Based on the perception parameter configuration information and the BWP configuration information, a perception task is performed using the perception signal within one of the at least two first BWPs; or, based on the perception parameter configuration information and the BWP configuration information, a perception task is performed independently using the perception signal within each of the at least two first BWPs.

[0129] In this embodiment, if multiple BWPs configured in the BWP configuration information do not meet the first condition, the sensing execution node uses the sensing signal sent within one of the BWPs to perform sensing, and considers that the base station will no longer send sensing signals to subsequent or preceding BWPs of that BWP. Alternatively, the sensing execution node independently uses the sensing signals sent within each of the configured BWPs to perform sensing.

[0130] As an optional embodiment, the first condition includes at least one of the following:

[0131] (1) The intersection of the first BWPs in the frequency domain is not zero;

[0132] Condition (1) is the frequency domain intersection rule, which means that the frequency domain intersection of all BWPs allocated to the sensing execution node (such as the terminal) performing the speed measurement sensing task must be non-zero. It can also be understood that these BWPs have at least one common subcarrier.

[0133] For example, when the sensing execution node is a terminal, the base station needs to check the frequency domain configuration of these first BWPs to ensure that the subcarrier ranges of each first BWP overlap.

[0134] In some embodiments, as an optional implementation, the step of jointly performing a sensing task using sensing signals within at least two first BWPs based on the sensing parameter configuration information and the BWP configuration information includes:

[0135] Based on the sensing parameter configuration information and the BWP configuration information, a sensing signal is received on a common subcarrier of the at least two first BWPs;

[0136] and / or

[0137] Based on the sensing parameter configuration information and the BWP configuration information, a sensing signal is transmitted on a common subcarrier of the at least two first BWPs.

[0138] In this embodiment, in order to ensure that the intersection of all configured first BWPs in the frequency domain is not zero, sensing signals can always be transmitted and / or received on a common subcarrier without adjusting the frequency domain position due to BWP switching.

[0139] Condition (1) avoids frequency domain redistribution of the sensing signal, reduces RF tuning delay, and ensures frequency domain continuity of the sensing signal. Frequency domain intersection rules can prevent spectral jumps and improve frequency domain switching efficiency.

[0140] (2) The sensing signals are distributed at equal intervals in the time domain of each first BWP;

[0141] Condition (2) is a time-domain uniformity rule, whereby the sensed signal is evenly distributed in the time domain of each configured BWP. To ensure that the sensed signal is evenly distributed in the time domain of each first BWP, the subcarrier spacing (SCS) of each BWP can be set to... They should be directly proportional; as SCS increases, and This is also increased accordingly to ensure a uniform distribution of the sensed signal in the time domain; and / or, the subcarrier spacing (SCS) of each BWP is increased. They should be directly proportional; as SCS increases, The value is also increased accordingly to ensure that the sensing signal remains uniformly distributed at the BWP boundary.

[0142] (3) The duration of the first BWP is an integer multiple of the duration of the sensing signal time slot group;

[0143] Condition (3) is the BWP switching time rule. The duration of the BWP must be an integer multiple of the duration of the SS slot group. Ensure that the sensing signal at the BWP boundary is evenly distributed during the BWP switching process. For example: configure the SS slot group type within each BWP (such as type 1, type 2, etc.) and determine that the duration of each BWP is an integer multiple of the corresponding SS slot group time.

[0144] As an optional embodiment, when multiple BWPs configured in the BWP configuration information simultaneously meet the above conditions (1), (2) and (3), the multiple BWPs are used to jointly perform the perception task.

[0145] (4) The first BWP has a first identifier.

[0146] The network-side equipment is configured with multiple Base Stations (BWPs) for performing speed sensing tasks. At different times, specific BWP configurations are required to simultaneously meet the three conditions mentioned above for joint sensing measurements. To reduce the complexity and latency at the receiver when determining the appropriate BWP configuration, BWP configurations that support joint sensing task execution can be marked.

[0147] The first identifier can be used to mark BWPs capable of joint sensing measurements (or supporting joint sensing tasks). For example, the base station can choose to mark BWPs that support joint sensing tasks, clearly indicating which BWP configurations are suitable for joint sensing. Through marking, the UE can clearly know which BWP configurations have been confirmed by the base station as suitable for joint sensing, thus saving the complexity and computation time of manual judgment. The UE can react quickly, reducing the time that judgment delays may affect the speed measurement task and improving the overall system response speed.

[0148] In some embodiments, the subcarrier spacing (SCS) of each first BWP configured by the BWP configuration information is proportional to the first parameter; and / or, the SCS of each first BWP configured by the BWP configuration information is proportional to the second parameter.

[0149] In this embodiment, the subcarrier spacing (SCS) of each configured BWP is... They are directly proportional. As SCS increases, and The value is also increased accordingly to ensure a uniform distribution of the sensed signal in the time domain.

[0150] For example, if the SCS of a certain BWP is 15kHz, when the sensing signal is in that BWP at... When transmitting at high density, in a BWP with the SCS configured at 30kHz, the sensing signal should be... The density of transmission; in a BWP with the SCS configured at 60kHz, the sensing signal should be transmitted at... The density of the transmitted signal is adjusted to ensure a uniform distribution of the sensed signal in the time domain.

[0151] For example, Figure 7 illustrates the process of a base station transmitting sensing signals to a sensing terminal. The base station configures different Base Station Window (BWP) configurations for the UE at different times to transmit sensing signals and communication data. Specifically, BWP#1 has an SCS configuration of 15kHz; BWP#2 has an SCS configuration of 30kHz. In BWP#1, the base station uses SS slot group type 3... The sensing signal is transmitted in three-slot increments. Furthermore, BWP#1 lasts for three time slots, which is the duration of SS slot group type 3. During BWP#2 transmission, the base station continues to transmit the sensing signal on the overlapping subcarriers of the two BWPs, avoiding frequency domain reallocation. Since the symbol duration of BWP#2 is 50% shorter than that of BWP#1, to ensure a uniform distribution of the sensing signal, in BWP#2, the base station transmits the sensing signal on the SS slot group type 3... Transmit sensing signals, that is, send one sensing signal every 6 symbols.

[0152] The subcarrier spacing (SCS) of each BWP can also be compared with... They should be directly proportional. As SCS increases, The SCS is also increased accordingly to ensure that the sensing signal remains uniformly distributed at the BWP boundary. For example, as shown in Figure 8: the SCS configuration of BWP#1 is 15kHz; the SCS configuration of BWP#2 is 30kHz. The base station in BWP#1 uses SS slot group type 3... The base station transmits sensing signals at a density of one signal every three symbols. Furthermore, BWP#1 lasts for three time slots, which is the duration of SS slot group type 3. During BWP#2 transmission, the base station continues to transmit sensing signals on the subcarriers where the two BWPs overlap. In BWP#2, the signal transmission density is... The density of transmission. If a BWP with an SCS of 60kHz is also included, the sensing signal should be transmitted in that BWP at a density of... The density of the signal is transmitted to ensure that the sensing signal remains uniformly distributed at the BWP boundary.

[0153] As an optional embodiment, the BWP configuration information is also used to configure at least one second BWP; the duration of the second BWP is less than the duration of the sensing signal time slot group.

[0154] In this embodiment, the aforementioned first BWP can be considered a regular BWP. Besides the regular BWPs described above whose duration is an integer multiple of the SS slot group duration, a special BWP with a more flexible duration, namely the second BWP, is defined. The length of the second BWP is less than the SS slot group duration. This second BWP can be applied when the required sensing signal transmission duration is not an integer multiple of the SS slot group duration. After transmitting several regular BWPs (the first BWP), one or more special BWPs can be transmitted to supplement the required sensing signal duration without wasting time-domain resources.

[0155] In some embodiments, performing a sensing task based on the sensing parameter configuration information and the BWP configuration information includes: when the transmission duration of the sensing signal is not an integer multiple of the duration of the sensing signal time slot group, performing a sensing task using at least one first BWP and a second BWP based on the sensing parameter configuration information and the BWP configuration information.

[0156] For example, as shown in Figure 9, during the BWP#1 configuration duration, due to communication needs, the base station configures a large bandwidth for BWP#1, and the BWP#1 configuration duration must be an integer multiple of the SS slot group duration. At some point, the UE's communication needs end, but the UE still has sensing needs, and the sensing signal duration required for this sensing need is shorter than the SS slot group duration (three time slots in Figure 9). In this case, even if a narrowband BWP with a duration of three time slots is allocated, it will still result in a waste of time domain resources. To solve this problem, a special BWP (the second BWP) is introduced, whose length can be less than the SS slot group duration. The second BWP can be allocated before or after a continuous sensing signal transmission (containing one or more first BWPs). When the second BWP is allocated after the first BWP, a segment of appropriate time length should be extracted from the front of a first BWP as the second BWP, so that the sensing signal remains evenly distributed within the durations of both the first and second BWPs, as shown in Figure 9. When the second BWP is assigned in front of the first BWP, a segment of appropriate time length should be taken from the rear end of the first BWP as the second BWP. This can keep the sensing signal uniformly distributed throughout the duration of both the first and second BWPs.

[0157] It should be noted that the processing of sensing signals in the sensing processing method of this embodiment is also applicable to the processing of communication signals, so as to meet the needs of integrated sensing signals, which will not be elaborated here.

[0158] In the embodiments disclosed herein, the sensing function node configures sensing parameter configuration information, and the sensing execution node executes sensing tasks based on the sensing parameter configuration information and BWP configuration information. This ensures uniform distribution of sensing signals, improves the applicability of communication signals (e.g., PRS) as ISAC sensing signals, increases the flexibility of communication signal configuration, improves ISAC speed measurement performance, and provides important technical support for 6G integrated sensing. By setting frequency domain intersection rules, spectrum jumps can be avoided, improving frequency domain switching efficiency. This embodiment supports uniform distribution of sensing signals under different SCSs, which can improve speed measurement accuracy. This embodiment, through adaptation of switching time and SS slot group, ensures the regularity of time distribution, avoids the addition of redundant symbols in traditional schemes, and improves resource utilization.

[0159] As shown in Figure 10, this embodiment of the present disclosure also provides a sensing processing method applied to a sensing function node, the method comprising:

[0160] Step 1001: The sensing function node determines the sensing parameter configuration information according to the sensing requirements;

[0161] Step 1002: The sensing function node sends the sensing parameter configuration information to the sensing execution node; sensing refers to the sensing execution node detecting the parameters of objects in the environment, such as detecting the speed and position of objects.

[0162] The sensing parameter configuration information includes at least one of the following:

[0163] (1) The first parameter is used to determine the temporal density of the sensed signal; this first parameter can be expressed as: The time-domain density of the sensed signal is used to determine the maximum sensing range. The time-domain density of the sensed signal refers to the symbol sparsity (comb size) of the sensed signal in the time domain, such as sending the sensed signal once every X time-domain symbols.

[0164] First parameter This first parameter can be represented as the symbol sparsity (comb size) of the sensing signal (SS) in the time domain. For example: This means that a sensing signal is sent every four symbols in the time domain. The smaller the size, the larger the range of perception.

[0165] (2) The sensing signal slot group (SS slot group) is a time-domain resource unit for sensing signals. The sensing signal slot group is based on the first parameter. The numerical value determines the smallest time unit for configuring sensing signals. This can also be understood as configuring the time-domain resources of sensing signals at the granularity of sensing signal time slot groups. For example, configuring the time-domain resources of sensing signals as Y SS slot groups. When SS slot groups with the same configuration are consecutive, the sensing signals transmitted on consecutive SS slot groups can be guaranteed to be uniformly distributed.

[0166] Each SS slot group contains one or more time slots. When configuring the time domain resources of sensing signals, the sensing function nodes use SS slot groups as the basic unit for configuration.

[0167] (3) The second parameter is used to determine the symbol position of the first sensing signal in each sensing signal time slot group; the second parameter can be expressed as: This parameter can indicate the symbol position of the first sensing signal in each SS slot group, for example, indicating the symbol number (or symbol index) of the first sensing signal. This second parameter allows for more flexible configuration of sensing signal transmission.

[0168] (4) The number of time slot groups configured for sensing signals. This can also be understood as the number of SS slot groups configured, or the number of SS slot groups used to transmit sensing signals. The number of time slot groups configured for sensing signals is a positive integer greater than or equal to 1. The number of time slot groups configured for sensing signals determines the duration of the sensing signal, and thus the speed measurement resolution and accuracy. For example: if the required sensing duration is 10ms based on the sensing requirements, and the length of a sensing signal time slot group is 1ms, then the number of sensing signal time slot groups that need to be configured is 10.

[0169] In some embodiments, the number of time slots included in the sensing signal time slot group is determined according to the time domain density of the sensing signal;

[0170] When there are at least two sensing signal time slot groups, the sensing signals are uniformly distributed in at least two consecutive sensing signal time slot groups.

[0171] In this embodiment, the sensing execution node includes a terminal and / or a network-side device; the BWP configuration information is configured by the network-side device. In this embodiment, the sensing execution node is a device that performs sensing tasks, which can be a terminal or a network-side device, such as a base station. Performing sensing tasks may include sending sensing signals, receiving sensing signals, and performing sensing measurements. For example, the base station sends sensing signals, the terminal receives sensing signals and sends echo signals back to the base station; the operations performed by both the base station and the terminal can be considered as performing sensing tasks.

[0172] In some embodiments, the sensing function node is an independent node; or, the sensing function node is deployed on at least one of the following devices: a terminal, a base station, or a core network device. In this embodiment, the sensing function node may have the capability to configure sensing information and may be deployed on a terminal or network-side device, or it may be an independent device. The sensing function node can determine sensing parameter configuration information according to sensing requirements, such as one or more of the following: speed measurement resolution, speed measurement accuracy, and sensing requirement location. The sensing parameter configuration information may be configuration information of parameters related to the sensing signal. The sensing function node can also select a suitable sensing execution node (terminal and / or base station) according to the sensing requirements and send the sensing parameter configuration information to the sensing execution node.

[0173] The sensing execution node performs sensing tasks on the BWP configured in the BWP configuration information according to the sensing parameter configuration information, such as sending sensing signals, receiving sensing signals, and performing sensing measurements such as speed and position. The sensing signals corresponding to the sensing parameter configuration information are uniformly distributed in the time domain, which can ensure the applicability of multiplexed communication signals (such as positioning reference signals (PRS)) as sensing signals, increase the configuration flexibility of communication signals (such as PRS), and provide important technical support for the integration of sensing and communication.

[0174] The number of time slots contained in a sensing signal slot group (SS slot group) depends on the temporal density of the sensing signal (or the first parameter). Based on the temporal density of the sensing signal, it is necessary to ensure that the sensing signal is uniformly distributed in multiple consecutive sensing signal time slot groups.

[0175] The number of time slots contained in a sensing signal time slot group may vary depending on the temporal density of the sensing signal. Based on the number of time slots contained in a sensing signal time slot group, the sensing signal time slot group can be defined as various types (SS slot group type). The various types of SS slot groups will not be elaborated here.
