Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a method for configuring sensing resources, an electronic device, and a computer program product. Background Technology
[0002] Sensor integration technology is one of the key technologies of 6G. In addition to traditional communication functions, base stations possess the ability to sense targets, including information such as distance, speed, angle, and position. When terminals perform sensing services, they receive sensing data. Different sensing resource configurations at the transmitting end will affect the reception of sensing data. Sensing configuration information includes sensing time-frequency resources, sensing sequence generation methods, and multiplexing methods for sensing and communication resources.
[0003] In a base station-transmitter-receiver sensing mode, since both the transmission and reception of sensing data occur on the base station side, the terminal side does not need to parse the sensing data. However, in sensing involving User Equipment (UE), the UE needs to decode the sensing data to complete the sensing service. This requires the UE to be aware of the sensing resource configuration in order to complete the sensing service. In some special scenarios, the sensing resource configuration information may change at any time, and the UE needs to obtain the sensing configuration information in real time to respond to changes in sensing resources.
[0004] In related technologies, the UE cannot receive sensing data to complete sensing services because it cannot know the configuration of sensing resources. Summary of the Invention
[0005] This invention provides a method for configuring sensing resources, an electronic device, and a computer program product to at least solve the problem in related technologies that the UE side cannot know the configuration of sensing resources and cannot receive sensing data.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0025] Among related technologies, the integrated sensing technology is one of the key technologies of 6G. On the basis of realizing traditional communication functions, the base station has the ability to sense targets, including information such as the distance, speed, angle and position of the target. When the terminal performs sensing services, it receives sensing data. Different sensing resource configurations at the sending end will affect the reception of sensing data. Sensing configuration information includes sensing time and frequency resources, sensing sequence generation method, and multiplexing method of sensing and communication resources. For example, in waveform design, the industry has proposed a variety of sensing waveform design schemes: (1) Orthogonal Frequency Division Multiplexing (OFDM) of sensing signal and communication signal to ensure communication quality, but OFDM has large sidelobes and peak average, which is not conducive to sensing coverage. (2) The sensing signal uses the traditional radar LFM signal, and the communication signal follows the OFDM scheme; each maximizes the quality of sensing and communication, but the inconsistency of the waveform system is not conducive to unified system scheduling and management. (3) The sensing signal and communication signal use the OTFS scheme, which can adapt to the sensing needs under high-speed movement, but the disadvantage is that the complexity is high.
[0026] In the base station-transmitter-receiver sensing mode, since both the transmission and reception of sensing data occur on the base station side, the terminal side does not need to parse the sensing data. However, in UE-involved sensing, the UE needs to decode the sensing data to complete the sensing service, requiring the UE to be aware of the sensing resource configuration in order to complete the sensing service. In some special scenarios, the sensing resource configuration information may change at any time, and the UE needs to obtain the sensing configuration information in real time to respond to changes in sensing resources.
[0027] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for implementing the perceptual resource allocation method in an embodiment of the present invention. For example... Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.
[0028] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the perceptual resource configuration method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.
[0029] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.
[0030] This invention provides a communication method that can be used to sense resource allocation. Figure 2 This is a flowchart of the perceptual resource configuration method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:
[0031] In step S202, the first node receives a sensing signal and a first signaling from the second node, wherein the first signaling carries sensing resource configuration information.
[0032] In this embodiment of the invention, the first node may be a terminal and the second node may be a base station.
[0033] In one exemplary embodiment, the type of the first signaling includes at least one of the following: physical signaling; Medium Access Control Element (MAC CE) signaling; Radio Resource Control (RRC) signaling.
[0034] In this embodiment of the invention, the first signaling includes, but is not limited to, physical signaling, MAC CE signaling, RRC signaling, etc.
[0035] In one exemplary embodiment, the first node receiving a first signaling from a second node includes: in response to the first signaling being physical signaling, the first node receiving physical signaling from the second node via a physical downlink control channel; or, in response to the first signaling being MAC CE signaling, the first node receiving MAC CE signaling from the second node via a physical downlink shared channel; or, in response to the first signaling being RRC signaling, the first node receiving RRC signaling from the second node via a physical downlink shared channel.
[0036] In an exemplary embodiment, in response to the first signaling being RRC signaling, and the RRC signaling being used for message broadcasting, the perceived resource configuration information is encapsulated in Other System Information (OSI) messages.
[0037] In one exemplary embodiment, the perceived resource configuration information is encapsulated in the OSI model as an index value.
[0038] In one exemplary embodiment, the sensing resource configuration information includes at least one of the following: time-domain resource information for sensing services; frequency-domain resource information for sensing services; sensing sequence; and resource multiplexing method for sensing data and communication data.
[0039] In an exemplary embodiment, the resource reuse method of sensing data and communication data includes at least one of the following: subband frequency division of sensing data and communication data on a communication symbol; combing of sensing data and communication data on a communication symbol; non-orthogonal superposition of sensing data and communication data on a communication symbol; and exclusive use of sensing data on a communication symbol.
[0040] In this embodiment of the invention, the resource reuse methods for sensing data and communication data include, but are not limited to, the above four methods, which will not be described in detail here.
[0041] Step S204: The first node obtains sensing data based on the sensing resource configuration information carried by the first signaling.
[0042] In an exemplary embodiment, the first node obtains sensing data based on sensing resource configuration information carried by the first signaling, including: in response to the first signaling being physical signaling, the first node decodes the physical signaling from the physical downlink control channel based on the location information defined by the Control Resource Set (CORESET) and the search space, obtains sensing resource configuration information, and obtains sensing data based on the sensing resource configuration information.
[0043] In an exemplary embodiment, the first node obtains sensing data based on sensing resource configuration information carried by the first signaling, including: in response to the first signaling being MAC CE signaling, the first node demodulates and obtains the MAC CE signaling based on the physical downlink shared channel resource block carrying the MAC CE signaling indicated by the physical downlink control channel, and parses the MAC CE signaling through the first node's medium access control (MAC) layer to obtain sensing resource configuration information, and obtains sensing data based on the sensing resource configuration information.
[0044] In an exemplary embodiment, the first node obtains sensing data based on sensing resource configuration information carried by the first signaling, including: in response to the first signaling being RRC signaling, the first node demodulates the physical downlink shared channel resource block to obtain the RRC signaling, and obtains sensing resource configuration information by parsing the RRC signaling, and obtains sensing data based on the sensing resource configuration information.
[0045] In one exemplary embodiment, the method further includes: when the first signaling is RRC signaling and the RRC signaling is used for message broadcasting, the first node parses the broadcast message corresponding to the RRC signaling to obtain the perception resource configuration information.
[0046] The above steps provide a method for configuring sensing resources. A first node receives sensing signals and first signaling from a second node, whereby the first signaling carries sensing resource configuration information. The first node then obtains sensing data based on this information. This solves the problem in related technologies where the UE cannot obtain the sensing resource configuration and therefore cannot receive sensing data. It achieves the goal of enabling the UE to obtain the sensing resource configuration information and efficiently receive sensing data to complete sensing services.
[0047] The entities that perform the above steps can be base stations, terminals, etc., but are not limited to these.
[0048] This invention provides a communication method that can be used to sense resource allocation. Figure 3 This is another flowchart of the perceptual resource configuration method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:
[0049] In step S302, the second node sends a sensing signal and a first signaling to the first node, so that the first node can obtain sensing data corresponding to the sensing resource configuration information according to the first signaling, wherein the first signaling carries the sensing resource configuration information.
[0050] In this embodiment of the invention, the first node may be a terminal and the second node may be a base station.
[0051] In one exemplary embodiment, before the second node sends the sensing signal and the first signaling to the first node, the method further includes: the second node receiving sensing resource configuration information from the core network; and the second node generating the sensing signal based on the sensing resource configuration information.
[0052] In one embodiment, the core network device determines sensing resource configuration information, which includes time-domain resources for sensing: transmission period, time slot position, and symbol position, etc.; frequency-domain resources: number of resource blocks (RBs), offset, subcarrier position, etc.; and sensing sequence: sequence generation formula, cyclic displacement, etc.
[0053] In one exemplary embodiment, the type of the first signaling includes at least one of the following: physical signaling; Media Access Control Element (MAC CE) signaling; Radio Resource Control (RRC) signaling.
[0054] In an exemplary embodiment, in response to the first signaling being RRC signaling and the RRC signaling being used for message broadcasting, the second node broadcasts the RRC signaling to the first node through periodic broadcasting or on-demand broadcasting.
[0055] In this embodiment of the invention, the distribution of sensing resource configuration based on RRC broadcast can be implemented by periodic broadcast or on-demand broadcast. In periodic broadcast, messages are broadcast at fixed intervals. In on-demand broadcast, the access network device broadcasts sensing resource messages only when it receives a sensing resource request from a terminal.

Thus, the present invention is not limited to any particular combination of hardware and software.
[0080] To enable those skilled in the art to better understand the technical solutions of the present invention, the following description is provided in conjunction with different embodiments.
[0081] Example 1
[0082] In this embodiment, the access network device is the second node in the above embodiments, and the terminal device is the first node in the above embodiments.
[0083] Figure 4 The flowchart of the sensing resource allocation method according to an embodiment of the present invention is as follows: Figure 4 As shown, it includes the following steps:
[0084] In step S401, the core network device determines the sensing resource configuration information and sends the sensing resource configuration information to the access network device.
[0085] In this embodiment of the invention, the sensing resource configuration information includes information such as time-domain resources, frequency-domain resources, and sensing sequence generation methods used for sensing.
[0086] In this embodiment of the invention, for any sensing resource configuration information, the core network device sends it to the access network device (5G gNB) via a message.
[0087] In one embodiment, the core network device determines sensing resource configuration information, which includes time-domain resources for sensing: transmission period, time slot position, and symbol position, etc.; frequency-domain resources: number of resource blocks (RBs), RE offset, subcarrier position, etc.; and sensing sequences: sequence generation formula, cycle shift, etc. Based on the sensing resource configuration information, the resource reuse methods for sensing data and communication data that can be implemented include, but are not limited to, the following four schemes:
[0088] Resource reuse method 1 for sensing data and communication data: Sensing data and communication data are divided into subbands on a single communication symbol. Figure 5 This is a schematic diagram illustrating the principle of frequency division configuration of sensing data and communication data sub-bands according to an embodiment of the present invention, as shown below. Figure 5 As shown, sensing is achieved by reserving a certain number of subcarriers on the communication symbols. This configuration information, by configuring the subcarrier positions and sensing data, allows for the design of sensing signals with good performance, such as low sidelobes and a low peak-to-average power ratio. This scheme reduces the resource overhead of sensing on the system and exhibits good sensing performance.
[0089] Resource reuse method 2 for sensing data and communication data: Sensing data and communication data are configured separately on a single symbol. Figure 6 This is a schematic diagram illustrating the principle of the sorting and configuration of sensing data and communication data according to an embodiment of the present invention, as shown below. Figure 6As shown, sensing data and communication data each occupy a certain number of subcarriers through a combing method. This scheme gives sensing resources a large bandwidth advantage, but the sensing coverage distance will be limited.
[0090] Resource reuse method 3 for sensing data and communication data: Sensing data and communication data are directly superimposed on a single symbol (non-orthogonal). Figure 7 This is a schematic diagram illustrating the principle of non-orthogonal superposition of sensing data and communication data in an embodiment of the present invention, as shown below. Figure 7 As shown, both sensing and communication can occupy the full bandwidth, but their data are directly superimposed and not orthogonal, resulting in significant interference between them.
[0091] Resource reuse method 4 for sensing data and communication data: Sensing data occupies a separate communication symbol. Figure 8 This is a schematic diagram illustrating the principle of time-division configuration of sensing data and communication data according to an embodiment of the present invention, such as... Figure 8 As shown, the sensing data occupies a separate symbol, and sensing and communication are time-division multiplexed. This scheme allows for communication and sensing without interference, but it has a large overhead.
[0092] In step S402, the access network device (base station) sends a sensing signal based on the sensing resource configuration information and sends the sensing resource configuration information to the terminal device in the form of signaling.
[0093] In this embodiment of the invention, the signaling (i.e., the first signaling in the above embodiment) includes, but is not limited to, physical signaling, MAC CE signaling, RRC signaling, etc.
[0094] In one embodiment, the access network device generates a sensing signal based on configuration information and sends it to the terminal device. Simultaneously, the access network sends the configuration information of the sensing resources issued by the core network to the terminal via signaling. The signaling is not limited to physical signaling, MAC CE signaling, RRC signaling, etc.
[0095] (1) Sensing resource allocation information is sent to the terminal via physical signaling.
[0096] In one embodiment, physical signaling is the information exchange between the base station and the terminal at the physical layer. The location is mapped onto the Physical Downlink Control Channel (PDCCH) based on the CORESET and the search space. The access network device loads the perceived resource configuration information onto the relevant resource blocks of the PDCCH and sends it to the terminal.
[0097] (2) The resource configuration information is sent to the terminal via MAC CE signaling.
[0098] In one embodiment, MAC CE signaling is used for information exchange between the MAC layers of the base station and the terminal. The MAC CE signaling, containing sensing resource configuration information, is generated by the base station MAC layer, mapped by the base station physical layer to Physical Downlink Shared Channel (PDSCH) resources (the time-frequency domain location is indicated by the PDCCH), and then sent to the terminal.
[0099] (3) Perceived resource configuration information is sent to the terminal via RRC signaling.
[0100] In one embodiment, RRC signaling is used for information exchange between the base station and the terminal at the RRC layer. RRC signaling containing sensing resource configuration information is generated by the base station's RRC layer and multiplexed to the Signaling Radiobearer (SRB). After segmentation and other operations by the Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC) layer, and MAC layer, it can be multiplexed into the same transport block as downlink data and mapped to PDSCH resources by the base station's physical layer.
[0101] In one embodiment, in response to RRC signaling containing information for message broadcasting purposes, configuration information of the sensed resources may be encapsulated in Other System Information (OSI) messages. The system information includes: a Master Information Block (MIB), transmitted via the BCH and PBCH channels; a System Information Block Type 1 (SIB1), transmitted via the DL-SCH and PDSCH channels; and other system information OSI messages, the remaining SIBs excluding SIB1, transmitted on the Downlink Shared Channel (DL-SCH) and PDSCH channels.
[0102] In one embodiment, the access network device encapsulates configuration information in an OSI model using an index value (indicating sensing resource configuration information), with a value range of 1, 2, ..., N, where N is configurable, as shown below:
[0103] --ASN1START
[0104] --TAG-SIBx-START
[0105] SIBx::=SEQUENCE{
[0106] *******(Original message content)
[0107] Index(Index value of perceived resource configuration information) INTEGER(1, 2, ..., N) (range of values)
[0108] }
[0109] --TAG-SIBx-STOP
[0110] --ASN1STOP
[0111] In this embodiment of the invention, the distribution of sensing resource configuration based on RRC broadcast can be implemented by periodic broadcast or on-demand broadcast. In periodic broadcast, messages are broadcast at fixed intervals. In on-demand broadcast, the access network device broadcasts sensing resource messages only when it receives a sensing resource request from a terminal.
[0112] In step S403, the terminal device (UE) obtains sensing data based on the sensing resource configuration information and completes the sensing service.
[0113] In one embodiment, the terminal device receives signaling for sensing resource configuration information from the access network device, including the following situations:
[0114] (1) Sensing resource allocation information is sent to the terminal via physical signaling.
[0115] The terminal device decodes the sensing resource configuration signaling on the PDCCH according to the location defined by the search space, and obtains the sensing signal time and frequency resources according to the configuration information.
[0116] (2) The resource configuration information is sent to the terminal via MAC CE signaling.
[0117] The terminal physical layer demodulates the PDSCH to obtain the MACCE signaling according to the PDCCH location indicating the MAC CE signaling, and transmits the MAC CE signaling to the UE MAC layer for parsing to obtain the sensing resource configuration information. Based on the configuration information, it obtains the sensing signal time and frequency resources.
[0118] (3) Perceived resource configuration information is sent to the terminal via RRC signaling.
[0119] The terminal demodulates the PDSCH resources, transmits the data to the RRC layer for parsing, obtains the perception resource configuration information, and the UE obtains the corresponding perception data based on the perception resource configuration information to complete the perception service.
[0120] In this embodiment of the invention, in response to the RRC signaling containing information for message broadcasting purposes, the UE needs to complete the decoding of the broadcast message. Figure 9 This is a schematic diagram of the decoding process of perception resource configuration information based on RRC broadcast according to an embodiment of the present invention, as follows: Figure 9As shown. The process includes the following:

[0122] The UE detects the Synchronization Signal Block (SSB) and completes frame synchronization.
[0123] (2) Decode the Physical Broadcast Channel (PBCH).
[0124] The PBCH carries the minimum system information (Master Information Block, MIB). After the UE decodes the MIB, it can obtain the basic configuration information of the cell.
[0125] (3) Configure the search space.
[0126] Based on the configuration of PDCCH-ConfigSIB1 in the MIB, the terminal can find the CORESET0 (control resource set) and search space for PDCCH or Downlink Control Information (DCI) transmission.
[0127] (4) Blindly interpret DCI.
[0128] The UE performs blind decoding of the DCI in the search space, without relying on decoding attempts for specific information, in order to find the scheduling of system information.
[0129] (5) Radio Network Temporary Identifier (RNTI) resolution.
[0130] If DCI 1_0 is successfully decoded, the UE parses the time-frequency domain information of the RRC configuration based on the SI RNTI within it.
[0131] (6) Decode PDSCH (MIB).
[0132] Using the decoded DCI information, the UE can detect and decode the Physical Downlink Shared Channel (PDSCH) carrying SIB1.
[0133] (7) Decode SIB1 and other SIBx(index).
[0134] SIB1 contains important network information, such as cell parameters and scheduling information for other SIBs.
[0135] If the sensing resource indication information is carried on SIBx (x≠1), then the UE decodes SIBx and reads the communication sensing resource configuration index in SIBx according to the scheduling information of SIBx in SIB1.
[0136] (8) Synchronous communication to sense resources.
[0137] The UE synchronizes the communication resources and sensing resources of the transmitting end according to the parsed communication sensing resource configuration index. The time domain resources are not limited to the starting position, number of symbols, sensing period, etc. of the sensing signal; the frequency domain resources are not limited to the subcarrier position, subcarrier offset, number of RBs, etc.; the sensing sequence includes the sequence generation method used, the cyclic shift amount of the sequence, etc.
[0138] (9) The UE extracts sensing data to perform sensing services.
[0139] Example 2
[0140] In this embodiment, the access network device is the second node in the above embodiments, and the terminal device is the first node in the above embodiments.
[0141] In this embodiment, sensing data and communication data are transmitted in a sub-band frequency division multiplexing manner, and configuration information is transmitted based on physical signaling.
[0142] Step 1: The core network equipment determines the sensing resource configuration information and distributes the configuration information to the access network equipment. The configuration information includes the time-domain resources, frequency-domain resources, and sensing sequences used for sensing.
[0143] Core network configures sensing resource information: The core network determines the generation method of sensing signal sequence, the frame format position of sensing symbol transmission, and the subcarrier position of configured sensing resources and communication resources. The core network equipment loads the sensing resource configuration information into the relevant resource blocks of PDCCH and sends it to the terminal.
[0144] Step 2: The access network device sends a sensing signal according to the configuration information and distributes the configuration information to the terminal device in the form of physical signaling. The physical signaling is the information exchange between the base station and the terminal at the physical layer, and is mapped onto the PDCCH channel according to the location defined by CORESET and the search space.
[0145] Step 3: The terminal device (UE) obtains sensing data based on the configuration information and completes the sensing service.
[0146] The terminal device decodes the sensing resource configuration signaling on the PDCCH based on the location defined by CORESET and the search space, and obtains the sensing signal time-frequency resources according to the configuration information. It then extracts the sensing data and completes the sensing service.
[0147] Example 3
[0148] In this embodiment, the access network device is the second node in the above embodiments, and the terminal device is the first node in the above embodiments.
[0149] In this embodiment, the sensing data and communication data are configured in a direct overlay (non-orthogonal) manner, and the sensing resource configuration information is distributed via RRC broadcast.
[0150] Step 1: The core network equipment determines the sensing resource configuration information and distributes the configuration information to the access network equipment. The configuration information includes the time-domain resources, frequency-domain resources, and sensing sequences used for sensing.
[0151] The core network configures sensing resource information: The core network determines the generation method of sensing signal sequences, the frame format and position of sensing symbol transmission, and the subcarrier positions of sensing and communication resources. The core network equipment loads the sensing resource configuration information onto the RRC signaling. The RRC signaling is generated by the base station RRC layer and multiplexed to the radio bearer (SRB). After being segmented by the PDCP, RLC layer and MAC, it can be multiplexed into the same transport block as downlink data and mapped to PDSCH resources by the base station physical layer.
[0152] Step 2: The access network device sends a sensing signal according to the configuration information and sends the configuration index to the terminal device in the form of physical RRC signaling.
[0153] When RRC signaling includes information for message broadcasting purposes: configuration information for perceived resources is encapsulated in a System Message (OSI). The OSI is transmitted on the DL-SCH and PDSCH channels.
[0154] Access network devices encapsulate configuration information in OSI (excluding SIB1's SIBx) using index values (indicating sensing resource configuration information). This can be achieved through periodic broadcasting or on-demand broadcasting. In periodic broadcasting, messages are broadcast at fixed intervals. In on-demand broadcasting, the access network device broadcasts sensing resource messages only when it receives a sensing resource request from a terminal.
[0155] Step 3: The terminal device (UE) obtains sensing data based on the configuration information and completes the sensing service.
[0156] The terminal demodulates the PDSCH resources, transmits the data to the RRC layer for parsing, obtains the sensing resource configuration information, and the UE obtains the corresponding sensing data based on the sensing resource configuration information to complete the sensing service. When the RRC signaling contains information for message broadcasting, the UE uses... Figure 9 The process shown completes the decoding of the broadcast message.
[0157] In summary, the sensing resource configuration method provided by this invention enables the UE to obtain sensing resource configuration information during the UE's sensing process, extract sensing data based on the configuration information, and then complete sensing service operations. Especially when the sensing resource configuration information changes, it avoids the need for the UE to perform numerous and frequent information interactions to obtain the sensing resource configuration, thus reducing system resource overhead.
