[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202410059607.0 filed in China on January 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a transmission configuration method, apparatus, and device. Background Art

[0004] At present, the collaborative synaesthesia network built on the basis of large-scale deployment of mobile communication networks has the advantages of collaborative reception and fusion processing gain, no need for self-interference deletion, no need for hardware modification, and low-cost and rapid technology implementation.

[0005] However, in actual networking, the collaborative sensing mode, where base station A transmits and base station B receives, requires changes to the uplink and downlink configurations of the transceiver base stations, breaking with traditional uplink and downlink configurations and introducing interference. As shown in Figure 1, node B simultaneously receives the uplink signal from its service users while receiving the sensing signal reflection. This means that in addition to receiving the reflected signal from node A that reaches node B after passing through the detected target, node B also receives uplink communication signals from service users 1-3 within its coverage area. Consequently, the uplink communication signal and the sensing signal reflection interfere with each other. Summary of the Invention

[0071] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0072] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present disclosure. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0073] In the various embodiments of the present disclosure, it should be understood that the size of the serial numbers of the following processes does not mean 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 the present disclosure.

[0074] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0075] In the embodiments provided in the present disclosure, it should be understood that "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0076] For ease of understanding, some contents involved in the embodiments of the present disclosure are described below:

[0077] 1. Perception

[0078] An integrated communication and perception system refers to a system that has both communication and perception capabilities through integrated design (spectrum resource sharing, integrated air interface, integrated hardware architecture, etc.), multi-point collaboration, and intelligent information interaction. Its working modes are divided into two categories: independent perception and collaborative perception.

[0079] 1. Independent Perception: Node A transmits a synaesthesia signal and receives the target's reflected signal, acquiring characteristic parameters of the surrounding environment and implementing sensing functions such as target detection, positioning, identification, and tracking. The advantage is that it can sense off-network targets without the assistance of other on-network nodes. The main challenges lie in the low energy of the echo signal and the presence of self-interference.

[0080] 2. Collaborative sensing mode: Node A transmits a synaesthesia signal, and collaborative node B receives the reflected signal from the target to be sensed. Then, through information exchange and fusion processing between one or more nodes, the environmental characteristic parameters between the transmitting and receiving nodes are obtained. The advantages are the elimination of self-interference between transmission and reception, and the ability to achieve collaborative reception processing gain through multi-node collaboration. The main challenge lies in inter-node synchronization.

[0081] 2. Uplink Resource Configuration Method

[0082] 1. New Radio (NR) Physical Uplink Shared Channel (PUSCH) Resource Configuration Method

[0083] (1) Time domain resource allocation:

[0084] Time domain allocation type A (slot scheduling) or type B (mini-slot scheduling), core parameter k2, start symbol S, symbol length L, and mapping type. This means that the time domain only supports continuous symbol-level configuration of "S+L" and does not support non-continuous configuration.

[0085] 1) Standby state: query the default table directly to obtain k2, S, L, mapping type through the lookup index determined by the corresponding field of the downlink control information (DCI)

[0086] i) Determine the table to be looked up in the standby state: find the corresponding table according to the normal cyclic prefix (CP) or the extended CP.

[0087] ii) Determine the specific row number based on the Time Domain Resource Assignment (TDRA) field in DCI0_0 or DCI0_1, and read k2, S, L, and mapping type.

[0088] 2) Radio Resource Control (RRC) connection transition: (RRC configuration list + DCI selection)

[0089] i) Obtain the time domain configuration list from the PUSCH allocation list (PUSCH-allocationList) in the PUSCH configuration (PUSCH-configcommon) of the higher-layer RRC signaling;

[0090] ii) Using the specific configuration of the TDRA field in the DCI, obtain k2, mapping type, start and length indicator value (SLIV).

[0091] (2) Frequency domain resource allocation:

[0092] PUSCH supports continuous and non-continuous frequency domain resource configuration, and its allocation granularity is resource block group (RBG) level.

[0093] 1) Type 0: Uses a bitmap stored in the corresponding field in the DCI to indicate RBG frequency domain allocation, supporting both continuous and non-continuous allocations. The configuration granularity is the RBG size, which corresponds to the Bandwidth Part (BWP) size.

[0094] 2) Type 1: uses the "start point + length" method, which can only implement continuous resource block (RB) allocation.

[0095] 2. NR Physical Uplink Control Channel (PUCCH) Resource Configuration: The PUCCH carries uplink control information (UCI). Since the current protocol does not support simultaneous transmission of PUCCH and PUSCH, when there is a conflict between the two channels, one channel is selected to transmit UCI. The specific principle is: when there is no user data on the PUSCH, the PUCCH transmits it; otherwise, the PUSCH transmits UCI.

[0096] In a collaborative sensing network, from the receiving end, there's a significant difference in the power of the uplink communication signal strength and the reflected signal strength of the sensing signal. Especially during medium- and long-range detection, the communication signal strength can be significantly greater than the reflected signal strength of the sensing signal. Because the receiver's ADC has a limited number of bits (e.g., a 10-bit ADC dynamic range = 10 * 6.02 + 1.72 dB), if the reflected signal strength of the sensing signal differs significantly from the communication signal strength, exceeding the available dynamic range of the hardware ADC, the weaker sensing signal will be overwhelmed, preventing effective acquisition.

[0097] At present, the NR system adopts the same-frequency deployment mode. When scheduling uplink resources (PUCCH, PUSCH), there is no need to consider the impact of other network nodes on the resource scheduling of this cell. For collaborative perception, A sends and B receives, and when A is downlink and B is uplink, when scheduling uplink resources (PUCCH, PUSCH), it is necessary to avoid conflicts with the downlink resources of base station A sending the perception signal. At the same time, because the existing uplink resource scheduling configuration mode of NR only supports continuous symbol-level configuration of "start symbol + symbol length" in the time domain, it does not support discontinuous configuration; the frequency domain supports continuous (start symbol + symbol length) and discontinuous bitmap frequency domain resource configuration, where the frequency domain granularity of the discontinuous bitmap allocation is RBG level, and its size is related to the BWP size.

[0098] As shown in FIG2 , a transmission configuration method according to an embodiment of the present disclosure is executed by a terminal, including:

[0099] Step 201: Receive first configuration information sent by a first network device, where the first configuration information includes resource configuration for zero-power uplink transmission;

[0100] Step 202: Perform uplink transmission based on the first configuration information.

[0101] Here, the first configuration information includes resource configuration for zero-power uplink transmission, that is, the first configuration information configures zero-power uplink transmission resources, or it can be understood that the first configuration information configures resources not used for uplink transmission or resources to be avoided.

[0102] In this way, the terminal executes steps 201 and 202, and after receiving the first configuration information sent by the first network device, it can perform uplink transmission (non-zero power uplink transmission) on resources other than the zero power uplink transmission resources configured by it based on the first configuration information to avoid conflicts between uplink transmission and perception signals.

[0103] The terminal can determine candidate resources for uplink transmission. For example, if the first network device sends third configuration information to the terminal, the third configuration information includes a resource configuration for uplink transmission. In this case, the third configuration information indicates the candidate resources for uplink transmission. In this way, the terminal, in combination with the first configuration information, can determine the target resource for uplink transmission, i.e., the candidate resources excluding the zero-power uplink transmission resource. Furthermore, the terminal performs uplink transmission on the target resource.

[0104] It should be noted that in this embodiment, uplink transmission is performed based on the first configuration information, i.e., zero-power uplink transmission is sent based on the first configuration information. Alternatively, it can be understood that no uplink transmission is performed on the zero-power uplink transmission resources configured based on the first configuration information. When sending zero-power uplink transmission, sequence generation is not required for zero-power uplink transmission.

[0105] Optionally, in this embodiment, the uplink transmission is non-zero-power uplink transmission, which is a transmission sent by the terminal to the first network device, and is uplink communication between the terminal and the first network device. The uplink transmission includes the terminal sending an uplink signal, uplink data, etc. to the first network device. The uplink signal may be an uplink reference signal. Accordingly, sending a zero-power uplink transmission may include sending a zero-power uplink reference signal or zero-power uplink data.

[0106] Among them, the resource configuration of uplink transmission can be achieved through PUCCH scheduling information, PUSCH scheduling information, and uplink reference signal configuration information.

[0107] For example, as shown in Figure 3, the candidate resources for uplink transmission are the resources included in the shaded area in the figure, and the zero-power uplink transmission (such as the zero-power uplink reference signal (Zero power-Reference Signal, ZP-RS)) resources configured by the first configuration information are the resources circled in the dotted circle in the figure. The terminal sends ZP-RS on the resources circled in the dotted circle in the figure, or it can be understood as sending a reference signal (Reference Signal, RS) on the resources other than the area circled in the shaded area in the figure.

[0108] Optionally, the resources indicated by the first configuration information are related to configuration parameters of the perception signal sent by the second network device.

[0109] Here, the perception signal is also called the perception reference signal or the collaborative perception signal.

[0110] In this embodiment, the second network device sends a perception signal, and the first network device receives a reflected signal of the perception signal, which is also called an echo signal or a perception echo signal. The resources indicated by the first configuration information, that is, the resources for zero-power uplink transmission configured by the first configuration information, are also called zero-power uplink transmission resources. The configuration parameters of the perception signal sent by the second network device are parameters that can determine the echo signal resources of the perception signal. Therefore, the resources indicated by the first configuration information are related to the configuration parameters of the perception signal sent by the second network device, which can be understood as the zero-power uplink transmission resources being the same as the echo signal resources, or the zero-power uplink transmission resources including the echo signal resources.

[0111] Specifically, as shown in Figure 4 , the second network device is base station 1, and the first network device is base station 2. Base station 1 transmits a sensing signal, such as SS1, and base station 2 receives a sensing echo signal from a detected target. Base station 2 also provides services for user equipment (UE) 1-2. Assume that base station 2 sends first configuration information to UE1 to configure resources for zero-power uplink transmission, and sends first configuration information to UE2 to configure resources for zero-power uplink transmission. These resources are the same as the transmission resources for the sensing echo signal. In this case, UE1 and UE2 will not perform uplink transmission on the zero-power uplink transmission resources. That is, UE1 will transmit ZP-RS1 on the zero-power uplink transmission resources, and UE2 will transmit ZP-RS2 on the zero-power uplink transmission resources.

[0112] Therefore, in the collaborative perception networking scenario, the first network device sends the first configuration information to build a unified uplink and downlink frame structure for the entire network. The terminal does not perform uplink transmission on the zero-power uplink transmission resource according to the configuration of the first network device, so as to avoid the conflict between the reflected signal of the perception signal and the uplink transmission.

[0113] Optionally, in this embodiment, the receiving the first configuration information sent by the first network device includes:

[0114] The first configuration information sent by the first network device is received when there is a conflict between the uplink transmission of the terminal and the transmission of the perception signal.

[0115] That is, when it is determined that the uplink transmission of the terminal conflicts with the transmission of the perception signal, the first network device sends first configuration information to the terminal to notify the terminal not to perform uplink transmission on the transmission resources of the perception signal to avoid conflicts between transmissions.

[0116] Here, there is a conflict between the uplink transmission and the transmission of the perception signal, which can also be understood as a conflict between the uplink transmission and the transmission of the perception echo signal.

[0117] Optionally, the first network device obtains second configuration information, where the second configuration information includes a resource configuration for the perception signal. The first network device may also obtain third configuration information to obtain resource configuration for uplink transmission of the terminal. In this way, the first network device can determine whether there is a conflict between the uplink transmission of the terminal and the transmission of the perception signal based on the second and third configuration information.

[0118] Specifically, the first network device obtains the second configuration information from the second network device or the perception server.

[0119] In this embodiment, the resource configuration of the sensing signal includes but is not limited to one or more of a sensing signal identifier (ID), a sensing resource time-frequency position, a transmission period, etc. For example, the sensing task is completed by multiplexing a Channel State Information-Reference Signal (CSI-RS) signal, and its sensing resource time-frequency position includes but is not limited to the time domain starting symbol, the number of symbols, and the frequency domain starting physical resource block (PRB), the number of PRBs, the bitmap configuration, the time domain comb, the frequency domain comb, etc. These configurations can be determined from the non-zero power CSI-RS resource set (NZP-CSI-RS-ResourceSet) in the CSI resource configuration (CSI-Resource-config) of the Channel State Information (CSI) configuration (CSI-MeasConfig) of the serving cell configuration (ServingCellConfig).

[0120] Of course, if there is no conflict between the uplink transmission and the transmission of the perception signal, the first network device does not need to send the first configuration information to the terminal.

[0121] Optionally, the receiving first configuration information sent by the first network device includes:

[0122] Receive the first configuration information sent by the first network device when the priority of the perceived communication is higher than the priority of the uplink communication.

[0123] That is, when the priority of perception communication is higher than the priority of uplink communication, the first network device will send first configuration information to the terminal to notify the terminal not to perform uplink transmission on the transmission resources of the perception signal, so as to ensure the smooth progress of perception communication.

[0124] Specifically, the priority of the perception communication and the priority of the uplink communication are predefined or configured. In addition, when the priority of the perception communication is higher than the priority of the uplink communication, the first network device may send the first configuration information even if it is determined that there is no conflict between the uplink transmission of the terminal and the transmission of the perception signal.

[0125] Of course, if the priority of the perception communication is lower than the priority of the uplink communication, the first network device may not send the first configuration information to the terminal.

[0126] Optionally, in this embodiment, the first configuration information includes at least one of the following:

[0127] Resource indication information, where the resource indication information is used to indicate resources for zero-power uplink transmission;

[0128] Resource type, where the resource type is a type of resource for zero-power uplink transmission;

[0129] A first identifier is used to indicate a resource mapping pattern of a perception signal.

[0130] That is, the first configuration information includes the resource indication information, and the terminal can determine the resource for zero-power uplink transmission based on the indication of the resource indication information. The first configuration information includes the resource type (resourceType), and the terminal can understand the specific type of the resource for zero-power uplink transmission based on the resource type. The first configuration information includes the first identifier, and the terminal can obtain the resource mapping pattern of the perception signal based on the first identifier.

[0131] Optionally, the resource indication information includes at least one of the following: a resource set release list (ResourceSetToReleaseList), a resource set index (ResourceSetId), a resource index (ResourceId), and a resource element pattern (ResourceElementPattern);

[0132] The resource type includes at least one of the following: aperiodic, periodic, and semi-static.

[0133] Optionally, the first configuration information further includes:

[0134] Resource use, the resource use including a first use, or the first use and a second use;

[0135] The first purpose is used to indicate that the resources indicated by the first configuration information are used for zero-power uplink transmission.

[0136] Here, if the resource usage included in the first configuration information only includes the first usage, the implementation of the first configuration information can be considered as a dedicated configuration of the zero-power uplink transmission resource; if the resource usage included in the first configuration information includes the first usage and the second usage, the implementation of the first configuration information can be considered as configuring the zero-power uplink transmission resource by multiplexing the second usage configuration. The second usage is a usage other than the resource indicated for zero-power uplink transmission.

[0137] For example, in Example 1, a dedicated configuration of a zero-power uplink transmission resource, such as the implementation of the zp-rs-Config configuration, is to add a zp-rs-Config configuration to the RRC signaling uplink BWP (UplinkBWP) configuration. Specifically, the structure of the UplinkBWP configuration is as follows:

[0138] In this way, zp-rs-Config is used to configure an uplink zero-power reference signal to circumvent the sensing resources of uplink communication and avoid interference between the sensing echo signal and uplink transmission in scenarios such as cooperative sensing.

[0139] For another example, in Example 2, the configuration of zero-power uplink transmission resources reuses the sounding reference signal (SRS) configuration. In the SRS-Config of the RRC signaling uplinkBWP configuration, a new usage is added to the SRS resource set information element (SRS-ResourceSet IE), and the listed uses include the first use and the second use. The first use is such as cooperative sensing; the second use is such as beam management (beamManagement), codebook (codebook), non-codebook (nonCodebook), and antenna switching (antennaSwitching), that is, in the SRS-ResourceSet IE, ENUMERATED {beamManagement, codebook, nonCodebook, antennaSwitching, cooperative sensing}. Specifically, the structure of the UplinkBWP configuration is as follows:

[0140] Thus, in SRS-Config, when usage = "cooperative sensing", resources associated with the resources of the collaborative sensing signal (Configure and collaborate-Sensing Signal, NZP-SS) (SS1) are configured to avoid interference between the sensing echo signal and uplink transmission.

[0141] For the method of Example 2, new patterns may be added later based on communication and perception requirements.

[0142] In addition, optionally, in this embodiment, the first identifier is a global identifier associated with the resource mapping pattern of the perception signal, or a local identifier associated with the resource mapping pattern of the perception signal in the first network device.

[0143] Here, the first identifier of the first configuration information may be the NZP-SSID as in Example 1 or 2 above.

[0144] It should be noted that the identifier associated with the resource mapping pattern of the perception signal learned by the first network device may be notified by the second network device. If the identifier associated with the resource mapping pattern of the perception signal notified by the second network device, that is, the second identifier, is its local identifier, then there is a situation where the terminal cannot recognize it. Therefore, the first network device will convert the second identifier into a global identifier or the local identifier of the first network device, and carry it in the first configuration information and send it to the terminal. Of course, if the second identifier notified by the second network device to the first network device is a global identifier, no further conversion is required, and the second identifier is directly carried as the first identifier in the first configuration information and sent to the terminal.

[0145] In summary, the transmission configuration method of the disclosed embodiments involves a terminal receiving first configuration information sent by a first network device, including resource configuration for zero-power uplink transmission, and performing uplink transmission based on this first configuration information, thereby avoiding collisions between the reflected signal of the sensing signal and the uplink transmission, and thereby preventing sensing task failure. Without changing the PUSCH and PUCCH resource configuration methods, this method standardizes the UE's resource conflict avoidance behavior, enabling the UE to obtain resources for sensing functions, thus ensuring a certain degree of forward compatibility.

[0146] As shown in FIG5 , a transmission configuration method according to an embodiment of the present disclosure is performed by a first network device, including:

[0147] Step 501: Send first configuration information to a terminal, where the first configuration information includes resource configuration for zero-power uplink transmission.

[0148] Through this step, the first network device notifies the terminal of the resource configuration of zero-power uplink transmission, so that after receiving the first configuration information, the terminal performs uplink transmission based on the first configuration information, avoiding the conflict between the reflected signal of the perception signal and the uplink transmission, and then avoiding the failure of the perception task.

[0149] Optionally, the resources indicated by the first configuration information are associated with the perception signal sent by the second network device.

[0150] Optionally, before sending the first configuration information to the terminal, the method includes:

[0151] Acquire second configuration information and third configuration information; wherein the second configuration information includes resource configuration of the perception signal, and the third configuration information includes resource configuration of uplink transmission;

[0152] determining, according to the second configuration information and the third configuration information, whether there is a conflict between the uplink transmission and the transmission of the perception signal;
