Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a cooperative sensing signal transmission method, apparatus and electronic device. Background Technology

[0002] In New Radio (NR) systems, carrier aggregation (CA) technology combines high-frequency and low-frequency bands to improve communication performance. A user equipment (UE) can simultaneously perform reception or transmission operations on one or more aggregated component carriers (CCs), depending on its own capabilities.

[0003] In applications using CA (Carrier Detection) for joint sensing of high and low frequency bands, one design involves using the same number of Orthogonal Frequency Division Multiplexing (OFDM) symbols for both high and low frequency bands, with each OFDM symbol containing the same total number of subcarriers. However, different CCs may employ different subcarrier spacings (SCS), such as a smaller SCS for low frequency bands and a larger SCS for high frequency bands. This fragmentation of resources reduces resource utilization. Summary of the Invention

The specific technology and device form used by the terminal device are not limited.

[0020] The methods and apparatus provided in this application can be applied to a variety of scenarios, including at least one of the following: a first device sending first information to a second device on a first resource group set; a first device sending first information to multiple second devices on a first resource group set; multiple first devices sending first information to a second device on a first resource group set; and multiple first devices sending first information to multiple second devices on a first resource group set.

[0021] The first resource set refers to the set of resources used for sensing. The first resource set is used to transmit first information, which is information used for sensing. Resources refer to physical resources, time and / or frequency resources, or time-frequency resources. The first resource set may include two or more resource sets. A resource set refers to a group of resources. A resource set may include two or more resource subgroups. The number of resource sets in the first resource set, and the number of resource subgroups within each resource set, can be preset as needed; specific values ​​are not limited.

[0022] It should be noted that "resource group" can be replaced with "resource unit", "resource pool", or "resource block", etc., which have the same meaning, and will not be stated one by one below.

[0023] In this embodiment of the application, the first resource group sets transmit the first information, which may be transmitting the first information on a set of time and / or frequency resources. The first information refers to a signal or data. The signal includes at least one of the following: a sensing reference signal, or a sensing signal, or other reference signals, such as SRS, CSI-RS, SSB, PRS, or TRS, etc. The signal can be an uplink signal or a downlink signal.

[0024] It should be noted that the first resource set is used to transmit the first information, which can mean that all physical resources included in the first resource set are used to transmit the first information. Alternatively, it can mean that some physical resources included in the first resource set are used to transmit the first information, while the remaining physical resources are used for communication or other functions.

[0025] like Figure 1 As shown, this application embodiment provides a cooperative sensing signal transmission method, executed by a first device, which may include the following steps: S102: The first device sends a first instruction information to the second device. The first instruction information is used to instruct a first resource group set. The first resource group set is used to transmit first information, which is information for sensing.

[0026] The first device is a device for sending sensing signals, and the second device is a device for receiving sensing signals.

[0027] For example, the first device is a wireless access network device that transmits sensing signals, and the second device is a terminal that receives sensing signals. Alternatively, the first device is a terminal that transmits sensing signals, and the second device is a wireless access network device that receives sensing signals.

[0028] The first resource group set includes at least a first resource group and a second resource group. The first resource group and the second resource group satisfy at least one of the following: the subcarrier spacing of the first resource group and the second resource group is different, or the frequency bands to which the first resource group and the second resource group belong are different.

[0029] In one implementation, the first resource group and the second resource group satisfy at least one of the following: The bandwidth of the first resource group and the second resource group is the same; The first and second resource groups have the same time duration.

[0030] In one implementation, a first resource group belongs to a first frequency band, and a second resource group belongs to a second frequency band. The first resource group and the second resource group belong to different frequency bands. The first frequency band has a first subcarrier spacing, and the second frequency band has a second subcarrier spacing.

[0031] For example, the first resource group belongs to the high-frequency band, and the second resource group belongs to the low-frequency band. Or, the first resource group belongs to the low-frequency band, and the second resource group belongs to the high-frequency band. In this case, the center frequency of the high-frequency band is higher than the center frequency of the low-frequency band. The high-frequency band and the low-frequency band have different band numbers.

[0032] In this embodiment of the application, the first resource group belongs to the first frequency band, the second resource group belongs to the second frequency band, and the first frequency band and the second frequency band satisfy one of the following: The frequency band numbers for the first and second frequency bands are different; The center frequencies of the first and second frequency bands are different; The first and second frequency bands belong to different CCs; The first and second frequency bands belong to different sub-CCs.

[0033] The frequency band number can uniquely identify a frequency band, and different frequency bands have different frequency band numbers.

[0034] In one implementation, the first resource group is identified by a first frequency band number, and the second resource group is identified by a second frequency band number, wherein the first frequency band number and the second frequency band number are different.

[0035] In one implementation, the center frequency of the first resource group is different from the center frequency of the second resource group.

[0036] For example, the center frequency of the first resource group is f1 MHz, and the center frequency of the second resource group is f2 MHz. f1 and f2 are different, and both f1 and f2 are positive integers. In one example, f1 = 700 and f2 = 2600.

[0037] In this embodiment, "bandwidth" can also be replaced with "frequency domain width," which has the same meaning, and will not be stated individually below. Bandwidth can contain one or more frequency domain units. A frequency domain unit can be one or more resource blocks (RBs), one or more bandwidth portions (BWPs), or one or more sub-CCs.

[0038] In this embodiment, the time length may include one or more time units. A time unit may include one or more of the following: symbol, time slot, half-frame, frame, micro-slot, microsecond, millisecond, second, etc.

[0039] In one implementation, the first resource group and the second resource group satisfy at least one of the following: The time domain starting position of the first resource group is the same as that of the second resource group; The time domain end position of the first resource group is the same as that of the second resource group.

[0040] In this embodiment of the application, the first resource group set satisfies one of the following: All physical resources in the first resource group set are used to transmit the first information; A portion of the physical resources in the first resource group set are used to transmit the first information; A portion of the physical resources in the first resource group are used to transmit the first information, and a portion of the physical resources in the second resource group are used to transmit the first information.

[0041] In this embodiment of the application, the first resource set is further used to transmit second information, which is information for communication, including communication signals and / or communication data; the first resource set satisfies one of the following: All physical resources in the first resource group are used to transmit the first information, and all physical resources in the second resource group are used to send the second information. All physical resources in the first resource group are used to send the second information, and all physical resources in the second resource group are used to transmit the first information.

[0042] For example, some subcarriers in the first resource group set are used to transmit sensing signals, or some orthogonal frequency division multiplexing (OFDM) symbols in the first resource group set are used to transmit sensing signals.

[0043] For example, some physical resources in the first resource group are used to transmit sensing signals, and some physical resources in the second resource group are used to transmit sensing signals. Alternatively, all physical resources in the first resource group are used to transmit sensing signals, and all physical resources in the second resource group are used to transmit communication signals.

[0044] In this embodiment of the application, the first resource group may include multiple resource subgroups, such as M resource subgroups. The second resource group may include multiple resource subgroups, such as N resource subgroups. Wherein, M and N are both positive integers greater than 1, and M and N may be equal or unequal. For example, M = N.

[0045] In one implementation, the first resource group and the second resource group satisfy at least one of the following: The first resource group includes multiple resource subgroups, and the physical resource patterns used by these multiple resource subgroups for sending the first information are the same; The second resource group includes multiple resource subgroups, and the physical resource patterns used by these multiple resource subgroups to send the first information are the same.

[0046] The physical resources used to transmit the first information refer to the physical resources mapped by the sensed signal sequence. A physical resource pattern refers to a resource distribution pattern with a certain regularity, including: frequency domain resource patterns and / or time domain resource patterns. For example, a frequency domain resource pattern called "comb x" means that the sensed signal sequence is mapped once every x subcarriers in the frequency domain. Similarly, a time domain resource pattern called "comb y" means that the sensed signal sequence is mapped once every y symbols in the time domain.

[0047] In this embodiment of the application, the first indication information may be dynamic signaling or higher-layer signaling. Specifically, the first indication information may include at least one of the following: Downlink Control Information (DCI), Medium Access Control Control Element (MAC CE), or Radio Resource Control (RRC).

[0048] In this embodiment of the application, the first indication information satisfies one of the following: The first indication information includes a first field and a second field, where the first field is used to indicate the first resource group and the second field is used to indicate the second resource group; The first indication information includes a third field, where the first bit of the third field indicates the first resource group, and the second bit of the third field indicates the second resource group.

[0049] For example, a field in the DCI can be used to indicate the first resource group, and a field in the RRC can be used to indicate the second resource group. Alternatively, different bit states of the same field in the DCI can be used to indicate the first and second resource groups respectively.

[0050] In this embodiment of the application, in a scenario where there are multiple second devices, the first field and the second field can be sent to different second devices respectively.

[0051] For example, the first device is a base station, and the second device includes UE1 and UE2. The base station can send the first field to UE1 and the second field to UE2. The first field can be included in the RRC, and the second field can be included in the DCI.

[0052] In this embodiment of the application, in a scenario where there are multiple first devices, the first field and the second field can be sent to the second device by different first devices.

[0053] For example, the first device includes base station 1 and base station 2, and the second device includes the UE. Base station 1 can send a first field to the UE, and base station 2 can send a second field to the UE. The first field can be included in the DCI, and the second field can be included in the MAC CE.

[0054] S104: The first device sends the first information to the second device on the first resource group set.

[0055] In this embodiment of the application, the first resource group belongs to the first frequency band, the second resource group belongs to the second frequency band, the first frequency band has a first subcarrier spacing, the second frequency band has a second subcarrier spacing, and the first resource group and the second resource group can satisfy at least one of the following methods one and two.

[0056] Method 1: The ratio of the bandwidth of the first resource group to the bandwidth of the second resource group is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing.

[0057] For example, if the bandwidth of the first resource group is B1, the bandwidth of the second resource group is B2, B1 and B2 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then B1 / B2 = SCS1 / SCS2 can be set.

[0058] In this embodiment of the application, the first method described above can achieve frequency domain resource alignment, which can reduce resource fragmentation and improve resource utilization.

[0059] Method 2: The ratio of the time length of the first resource group to the time length of the second resource group is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0060] For example, if the time length of the first resource group is T1, the time length of the second resource group is T2, T1 and T2 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then T1 / T2 = SCS2 / SCS1 can be set.

[0061] In this embodiment of the application, the above-mentioned method two can achieve temporal resource alignment, reduce resource fragmentation problems, and improve resource utilization.

[0062] In this embodiment, either method one or method two can be used, or they can be used in combination. When method one and method two are used in combination, the following conditions can be met: the ratio of the bandwidth of the first resource group to the bandwidth of the second resource group is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing; and the ratio of the time length of the first resource group to the time length of the second resource group is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing. This configuration achieves alignment of both frequency domain and time domain resources, minimizing resource fragmentation and significantly improving resource utilization.

[0063] In this embodiment of the application, the first resource group may include multiple resource subgroups, and the second resource group may include multiple resource subgroups. The multiple resource subgroups in the first resource group may have the same bandwidth and / or the same duration. Similarly, the multiple resource subgroups in the second resource group may also have the same bandwidth and / or the same duration.

[0064] In one embodiment of this application, the first resource group and the second resource group satisfy at least one of the following: The first resource group contains multiple resource subgroups, and the center frequencies of the multiple resource subgroups are different; The second resource group contains multiple resource subgroups, and the center frequencies of these multiple resource subgroups are different.

[0065] For example, the first resource group includes two resource subgroups with the same center frequency, and / or the second resource group includes two resource subgroups with different center frequencies.

[0066] For example, the first resource group includes two resource subgroups with different center frequencies, and / or the second resource group includes two resource subgroups with the same center frequency.

[0067] For example, the first resource group includes two resource subgroups with different center frequencies, and / or the second resource group includes two resource subgroups with different center frequencies.

[0068] In this embodiment, the first resource group may include at least two resource subgroups, and the second resource group may include at least two resource subgroups. Any one or more resource subgroups in the first resource group may be associated with any one or more resource subgroups in the second resource group. It should be noted that associating multiple resource subgroups means that the sensing signals transmitted by these multiple resource subgroups are used for joint sensing.

[0069] In one embodiment of this application, the first resource group includes at least a first resource subgroup and a second resource subgroup, and the second resource group includes at least a third resource subgroup and a fourth resource subgroup. The first resource subgroup is associated with the third resource subgroup, and / or the second resource subgroup is associated with the fourth resource subgroup.

[0070] The subgroups of the first resource group and the subgroups of the second resource group can be set using at least one of the following methods: A, B, C, and D.

[0071] Method A: The ratio of the bandwidth of the first resource subgroup to the bandwidth of the third resource subgroup is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing.

[0072] For example, if the bandwidth of the first resource subgroup is B1, the bandwidth of the third resource subgroup is B3, B1 and B3 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then B1 / B3 = SCS1 / SCS2 can be set.

[0073] In this embodiment of the application, the above-mentioned method A can realize joint perception of resources in different frequency bands and frequency domain resource alignment, which can reduce the fragmentation problem of resources in collaborative perception scenarios and improve the utilization rate of resources.

[0074] Method B: The ratio of the time length of the first resource subgroup to the time length of the third resource subgroup is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0075] For example, if the time length of the first resource subgroup is T1, the time length of the third resource subgroup is T3, T1 and T3 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then T1 / T3 = SCS2 / SCS1 can be set.

[0076] In this embodiment of the application, the above-mentioned method B can realize joint perception of resources in different frequency bands and time domain resource alignment, which can reduce the fragmentation problem of resources in collaborative perception scenarios and improve resource utilization.

[0077] Method C: The ratio of the bandwidth of the second resource subgroup to the bandwidth of the fourth resource subgroup is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing.

[0078] For example, if the bandwidth of the second resource subgroup is B2, the bandwidth of the fourth resource subgroup is B4, B2 and B4 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then B2 / B4 = SCS1 / SCS2 can be set.

[0079] In this embodiment of the application, the above-mentioned method C can realize joint perception of resources in different frequency bands and frequency domain resource alignment, which can reduce the fragmentation problem of resources in collaborative perception scenarios and improve the utilization rate of resources.

[0080] Mode D: The ratio of the time length of the second resource subgroup to the time length of the fourth resource subgroup is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0081] For example, if the time length of the second resource subgroup is T2, the time length of the fourth resource subgroup is T4, T2 and T4 are positive integers, the first subcarrier spacing is SCS1, and the second subcarrier spacing is SCS2, then T2 / T4 = SCS2 / SCS1 can be set.

[0082] In this embodiment of the application, the above-mentioned method D can realize joint perception of resources in different frequency bands and time domain resource alignment, which can reduce the fragmentation problem of resources in collaborative perception scenarios and improve resource utilization.

[0083] In this embodiment of the application, the above-mentioned methods A, B, C and D can be freely combined, and one or more of them can be used. The implementation method is relatively flexible and highly practical.

[0084] Figure 2 This is a schematic diagram of the first resource group set provided in an embodiment of this application. For example... Figure 2 As shown, the first resource group set includes a first resource group and a second resource group. The center frequency of the first resource group is higher than that of the second resource group; for example, if the first resource group belongs to a high-frequency band, the second resource group belongs to a low-frequency band. The first resource group contains two resource subgroups: the first resource subgroup and the second resource subgroup. The second resource group also contains two resource subgroups: the third resource subgroup and the fourth resource subgroup. The first and third resource subgroups are associated, and the second and fourth resource subgroups are associated. The subcarrier spacing SCS1 of the first resource group is twice the subcarrier spacing SCS2 of the second resource group, i.e., SCS1 / SCS2 = 2.

[0085] In one implementation, the bandwidth of the first resource subgroup is B1=2W, and the bandwidth of the second resource subgroup is B2=W, satisfying B1 / B2=SCS1 / SCS2. In this case, frequency domain resource alignment can be achieved, ensuring that the total number of subcarriers of the sensing signals in the first and second frequency bands is the same, which is beneficial to the realization of joint sensing.

[0086] In one implementation, the time length of the first resource subgroup is T1=T, and the time length of the second resource subgroup is T2=2T, satisfying T1 / T2=SCS2 / SCS1. In this case, time-domain resource alignment can be achieved.

[0087] The frequency domain resource alignment and time domain resource alignment methods mentioned above can be used individually or in combination to avoid resource fragmentation and improve resource utilization.

[0088] In this embodiment of the application, when the subgroups of the first resource group and the subgroups of the second resource group are configured using one or more of methods A, B, C and D, the bandwidth of the first resource group and the second resource group are the same; and / or, the time length of the first resource group and the second resource group is the same.

[0089] In this embodiment of the application, when the subgroups of the first resource group and the subgroups of the second resource group are set using one or more of the methods A, B, C and D, the time domain start position of the first resource group and the time domain start position of the second resource group are the same; and / or, the time domain end position of the first resource group and the time domain end position of the second resource group are the same.

[0090] In one implementation, the first resource group set may include three resource groups, each belonging to a different frequency band. Specifically, the first resource group belongs to a first frequency band, the second resource group belongs to a second frequency band, and the third resource group belongs to a third frequency band. For example, the sum of the bandwidths of the second and third resource groups can be set to equal the bandwidth of the first resource group.

[0091] For example, the first resource group belongs to the first frequency band, which is a high-frequency band. The second and third resource groups both belong to the second frequency band, which is a low-frequency band, and the center frequency of the second resource group is higher than that of the third resource group. The bandwidth of the first resource group is 200MHz, the bandwidth of the second resource group is 100MHz, and the bandwidth of the third resource group is 100MHz. Through joint scheduling of resources in the two low-frequency bands, the total bandwidth of the low-frequency band can be made the same as that of the high-frequency band, which is beneficial for fully utilizing the large bandwidth for sensing and communication.

[0092] In this embodiment of the application, the above method may further include: The first device receives the sensing result information from the second device.

[0093] In one implementation, the aforementioned sensing result information includes sensing result information fed back by the second device for the first information transmitted on the first resource group set.

[0094] This implementation method provides feedback of a sensing result to the first resource group set. Feedback is performed at the resource group set granularity, which can reduce the amount of sensing results sent and save the transmission power consumption and transmission resources occupied by the second device.

[0095] In one implementation, the first resource group and the second resource group include at least one associated resource subgroup, which includes a subgroup in the first resource group and a subgroup in the second resource group, and the aforementioned perception result information includes perception result information fed back by the second device for each associated resource subgroup in the at least one associated resource subgroup.

[0096] In this implementation, a sensing result is fed back for each associated resource subgroup. Feedback is performed at the granularity of the associated resource subgroup. The sensing result corresponds to a more refined time-frequency resource, and the sensing result feedback is more precise. The second device, as a sensing device, can use each sensing result individually or use multiple sensing results in combination, making the application of sensing results more flexible.

[0097] The method provided in this application embodiment involves a first device sending first indication information to a second device and sending first information to the second device on a first resource group set.

The first resource group set includes at least a first resource group and a second resource group, which satisfy at least one of the following: the subcarrier spacing of the first resource group and the second resource group are different, or the frequency bands to which the first resource group and the second resource group belong are different. This process provides a resource group configuration method for sensing in scenarios involving multi-band cooperative transmission of information for sensing. Cooperative sensing based on resource groups with different subcarrier spacing and frequency bands greatly reduces resource fragmentation, improves resource utilization, and enhances the efficiency of cooperative sensing. Furthermore, it avoids power consumption waste caused by resource misalignment in the second device.

All physical resources in the first resource group are used to send the second information, and all physical resources in the second resource group are used to transmit the first information.

[0110] In this embodiment of the application, the first resource group may include multiple resource subgroups, such as M resource subgroups. The second resource group may include multiple resource subgroups, such as N resource subgroups. Wherein, M and N are both positive integers greater than 1, and M and N may be equal or unequal. For example, M = N.

[0111] In one implementation, the first resource group and the second resource group satisfy at least one of the following: The first resource group includes multiple resource subgroups and the physical resource patterns used by these multiple resource subgroups to send the first information are the same. The second resource group includes multiple resource subgroups, and the physical resource patterns used by these multiple resource subgroups to send the first information are the same.

[0112] In this embodiment of the application, the first indication information may be dynamic signaling or higher-layer signaling. Specifically, the first indication information may include at least one of the following: DCI, MAC CE, and RRC.

[0113] In this embodiment of the application, the first indication information satisfies one of the following: The first indication information includes a first field and a second field, where the first field is used to indicate the first resource group and the second field is used to indicate the second resource group; The first indication information includes a third field, where the first bit of the third field indicates the first resource group, and the second bit of the third field indicates the second resource group.

[0114] S304: The second device receives the first information from the first device on the first resource group set.

[0115] In this embodiment of the application, the first resource group belongs to the first frequency band, the second resource group belongs to the second frequency band, the first frequency band has a first subcarrier spacing, the second frequency band has a second subcarrier spacing, and the first resource group and the second resource group satisfy at least one of the following: The ratio of the bandwidth of the first resource group to the bandwidth of the second resource group is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing. The ratio of the time length of the first resource group to the time length of the second resource group is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0116] In this embodiment of the application, the first resource group may include multiple resource subgroups, and the second resource group may include multiple resource subgroups. The multiple resource subgroups in the first resource group may have the same bandwidth and / or the same duration. Similarly, the multiple resource subgroups in the second resource group may also have the same bandwidth and / or the same duration.

[0117] In one implementation, the first resource group and the second resource group satisfy at least one of the following: The first resource group contains multiple resource subgroups, and the center frequencies of the multiple resource subgroups are different; The second resource group contains multiple resource subgroups, and the center frequencies of these multiple resource subgroups are different.

[0118] In this embodiment of the application, the first resource group may include at least two resource subgroups, and the second resource group may include at least two resource subgroups. Any one or more resource subgroups in the first resource group may be associated with any one or more resource subgroups in the second resource group.

[0119] In one embodiment of this application, the first resource group includes at least a first resource subgroup and a second resource subgroup, and the second resource group includes at least a third resource subgroup and a fourth resource subgroup. The first resource subgroup is associated with the third resource subgroup, and the second resource subgroup is associated with the fourth resource subgroup.

[0120] The subgroups of the first resource group and the subgroups of the second resource group can be set using at least one of the following methods: A, B, C, and D.

[0121] Method A: The ratio of the bandwidth of the first resource subgroup to the bandwidth of the third resource subgroup is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing.

[0122] Method B: The ratio of the time length of the first resource subgroup to the time length of the third resource subgroup is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0123] Method C: The ratio of the bandwidth of the second resource subgroup to the bandwidth of the fourth resource subgroup is equal to the ratio of the first subcarrier spacing to the second subcarrier spacing.

[0124] Mode D: The ratio of the time length of the second resource subgroup to the time length of the fourth resource subgroup is equal to the ratio of the second subcarrier spacing to the first subcarrier spacing.

[0125] In this embodiment, methods A and C can both achieve joint sensing of resources across different frequency bands and frequency domain resource alignment, while methods B and D can both achieve joint sensing of resources across different frequency bands and time domain resource alignment. Regardless of the method, both can reduce resource fragmentation in collaborative sensing scenarios and improve resource utilization. Furthermore, methods A, B, C, and D can be freely combined, and one or more of them can be used, making the implementation flexible and highly practical.

[0126] In this embodiment of the application, when the subgroups of the first resource group and the subgroups of the second resource group are configured using one or more of methods A, B, C and D, the bandwidth of the first resource group and the second resource group are the same; and / or, the time length of the first resource group and the second resource group is the same.

[0127] In this embodiment of the application, when the subgroups of the first resource group and the subgroups of the second resource group are set using one or more of the methods A, B, C and D, the time domain start position of the first resource group and the time domain start position of the second resource group are the same; and / or, the time domain end position of the first resource group and the time domain end position of the second resource group are the same.

[0128] See Figure 2 The first resource subgroup and the third resource subgroup are associated, and the second resource subgroup and the fourth resource subgroup are associated. After the second device receives the sensing signal from the first device on the first resource group set, the second device can jointly process the sensing signals received on the first resource subgroup and the third resource subgroup, and jointly process the sensing signals received on the second resource subgroup and the fourth resource subgroup.

[0129] In this embodiment of the application, there can be multiple devices, i.e., second devices, that receive sensing signals on the first resource group set. For example, see... Figure 2 Device G, which receives sensing signals, receives sensing signals from the first device on the first resource subgroup and the third resource subgroup, and performs joint processing on the sensing signals received on the first and third resource subgroups. Device H, which also receives sensing signals, receives sensing signals from the first device on the second and fourth resource subgroups, and performs joint processing on the sensing signals received on the second and fourth resource subgroups. This method of multiple devices receiving sensing signals provides finer granularity and improves the flexibility of system scheduling.

[0130] In this embodiment, the number of devices receiving sensing signals on the first resource group set can be configured by the network or indicated by the network. This implementation allows the network to coordinate the allocation of sensing resources based on the system's resource occupancy, resulting in greater flexibility in system scheduling.

[0131] In this embodiment of the application, the above method may further include: The second device sends the sensing result information to the first device.

[0132] In one implementation, the aforementioned sensing result information includes sensing result information fed back by the second device for the first information transmitted on the first resource group set.

[0133] This implementation method provides feedback of a sensing result to the first resource group set. Feedback is performed at the resource group set granularity, which can reduce the amount of sensing results sent and save the transmission power consumption and transmission resources occupied by the second device.

[0134] In one implementation, the first resource group and the second resource group include at least one associated resource subgroup, which includes a subgroup in the first resource group and a subgroup in the second resource group, and the aforementioned perception result information includes perception result information fed back by the second device for each associated resource subgroup in the at least one associated resource subgroup.

[0135] For example, the first resource subgroup within the first resource group is associated with the third resource subgroup within the second resource group, and can be called associated resource subgroup U. The second resource subgroup within the first resource group is associated with the fourth resource subgroup within the second resource group, and can be called associated resource subgroup V. The second device can provide a sensing result for associated resource subgroup U and a sensing result for associated resource subgroup V.

[0136] In this implementation, a sensing result is fed back for each associated resource subgroup. Feedback is performed at the granularity of the associated resource subgroup. The sensing result corresponds to a more refined time-frequency resource, and the sensing result feedback is more precise. The second device, as a sensing device, can use each sensing result individually or use multiple sensing results in combination, making the application of sensing results more flexible.

[0137] The method provided in this application embodiment involves a second device receiving first indication information from a first device and receiving first information from the first device on a first resource group set. The first indication information indicates the first resource group set, and the first resource group set is used to transmit the first information, which is information for sensing. The first resource group set includes at least a first resource group and a second resource group, and the first and second resource groups satisfy at least one of the following: the subcarrier spacing of the first and second resource groups is different, or the frequency bands to which the first and second resource groups belong are different. This process provides a resource group configuration method for sensing in scenarios involving multi-band cooperative transmission of information for sensing. Cooperative sensing based on resource groups with different subcarrier spacing and frequency bands significantly reduces resource fragmentation, improves resource utilization, and enhances the efficiency of cooperative sensing. Furthermore, by aligning frequency domain resources and / or time domain resources, the receiving and processing time of the second device can be shortened, reducing data processing complexity. This facilitates the second device entering a sleep state promptly after receiving the first information, reducing power consumption and avoiding power waste.

The first resource group set includes at least a first resource group and a second resource group, and the first and second resource groups satisfy at least one of the following: the subcarrier spacing of the first and second resource groups is different, and the frequency bands to which the first and second resource groups belong are different. The above process provides a resource group configuration method for sensing in scenarios involving multi-band cooperative transmission of sensing information. Cooperative sensing based on resource groups with different subcarrier spacing and frequency bands greatly reduces resource fragmentation, improves resource utilization, and enhances the efficiency of cooperative sensing. Furthermore, by aligning frequency domain resources and / or time domain resources, the receiving and processing time of the second device can be shortened, reducing data processing complexity. This facilitates the second device entering a sleep state promptly after receiving the first information, reducing power consumption and avoiding power waste.
