Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a transmission configuration method, apparatus, and device. Background Art

[0002] Currently, a cooperative communication and sensing network built based on the large-scale deployment of mobile communication networks has advantages such as cooperative reception and fusion processing gain, no need for self-interference cancellation, no need for hardware modification, and low-cost and rapid technology implementation.

[0003] However, in actual network deployment, the cooperative sensing mode of base station A transmitting and base station B receiving requires changing the uplink and downlink configurations of the transmitting and receiving base stations, which breaks the traditional uplink and downlink configuration methods and introduces interference. For example, Figure 1 As shown, while node B receives the sensing signal reflected signal, it also needs to receive the uplink signals of its served users. That is, in addition to the reflected signal sent by node A and reaching B through the detected target, node B will also receive the uplink communication signals sent by served users 1-3 within its coverage area. Therefore, the uplink communication signals and the sensing signal reflected signals interfere with each other. Summary of the Invention

[0068] To make the technical problems, technical solutions and advantages to be solved by the present application clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0069] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, the "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0070] In various embodiments of the present application, it should be understood that the order numbers of the following processes do not mean the sequence of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0071] In addition, the terms "system" and "network" are often used interchangeably in this document.

[0072] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0073] For the convenience of understanding, some contents related to the embodiments of the present application are described below:

[0074] I. Sensing

[0075] The communication and sensing integrated system refers to a system that simultaneously has communication and sensing capabilities through integrated design (spectrum resource sharing, integrated air interface, integrated hardware architecture, etc.), multi-point cooperation, and information intelligent interaction. Its working modes are divided into two categories: independent sensing and cooperative sensing.

[0076] 1. Independent sensing: Node A sends a communication and sensing signal and receives the reflected signal of the target to obtain the characteristic parameters of the surrounding environment attributes, realizing sensing functions such as target detection, positioning, identification, and tracking. The advantage is that it can complete the non-in-network target sensing process without the assistance of other in-network nodes. The main challenge is the low energy of the echo signal and the existence of self-interference.

[0077] 2. Cooperative sensing mode: Node A sends a communication and sensing signal, and cooperative node B receives the reflected signal from the target to be sensed. Then, one or more nodes perform information interaction and information fusion processing among nodes to obtain the environmental characteristic parameters between the transceiver nodes. The advantages are no transmit-receive self-interference and the ability to obtain cooperative reception processing gain through multi-node cooperation. The main challenge is node synchronization.

[0078] II. Uplink resource allocation method

[0079] 1. New Radio (NR) Physical Uplink Shared Channel (PUSCH) resource allocation method

[0080] (1) Time-domain resource allocation:

[0081] Time-domain allocation types typeA (slot scheduling), typeB (mini-slot scheduling), the core parameter k2, the starting symbol S, the symbol length L, and the mapping type. That is, the time domain only supports the continuous symbol-level configuration of "S+L" and does not support discontinuous configuration.

[0082] 1) Standby state: The k2, S, L, and mapping type are directly obtained by querying the default table through the lookup table index determined by the corresponding field of the Downlink Control Information (DCI).

[0083] i) Determine the standby state table to be checked: Find the corresponding table according to the normal cyclic prefix (CP) or extended CP.

[0084] ii) Determine the specific row number according to the time domain resource assignment (TDRA) field in DCI0_0 or DCI0_1, and read k2, S, L, and mapping type.

[0085] 2) Radio Resource Control (RRC) connection state: (RRC configuration list + DCI selection)

[0086] i) Obtain the time domain configuration list from the PUSCH allocation list (PUSCH-allocationList) in the high-layer RRC signaling PUSCH configuration (PUSCH-configcommon).

[0087] ii) Use the specific configuration in the TDRA field of DCI to obtain k2, mapping type, start and length indicator value (SLIV).

[0088] (2) Frequency domain resource configuration:

[0089] PUSCH supports continuous and discontinuous frequency domain resource configuration, and its allocation granularity is at the resource block group (RBG) level.

[0090] 1) Type0: Use the bitmap stored in the corresponding field of DCI to indicate the RBG for frequency domain allocation, supporting continuous / discontinuous. Its configuration granularity is the RBG size, corresponding to the BandWidth Part (BWP) size.

[0091] 2) Type1: Use the "starting point + length" method, which can only achieve continuous RB allocation.

[0092] 2. NR Physical Uplink Control Channel (PUCCH) resource configuration method

[0093] The function of PUCCH is to carry Uplink Control Information (UCI). Since the current protocol does not support the simultaneous transmission of PUCCH and PUSCH, when there is a conflict between the two channels, one of the channels is selected to transmit UCI. The specific principle is as follows: when there is no user data on PUSCH, it is transmitted by PUCCH; otherwise, PUSCH transmits UCI.

[0094] In a cooperative sensing network, from the perspective of the receiving end, there are significant differences in the signal strength of the uplink communication signal and the reflected signal strength of the sensing signal. Especially during medium- and long-distance detection, the signal strength of the communication signal will be much greater than the reflected signal strength of the sensing signal. Due to the limited number of bits of the receiver ADC (for example, if it is 10 bits, then the ADC dynamic range = 10 * 6.02 + 1.72 dB), if the difference between the reflected signal strength of the sensing signal and the communication signal strength is too large and exceeds the available dynamic range of the hardware ADC, the sensing signal with a smaller strength will be submerged and cannot be effectively collected.

[0095] Currently, the NR system adopts a co-frequency deployment method. When scheduling uplink resources (PUCCH, PUSCH), it is not necessary to consider the impact of other network nodes on the resource scheduling of this cell. For cooperative sensing, when A transmits and B receives, and A is in the downlink and B is in the uplink, when scheduling uplink resources (PUCCH, PUSCH), it is necessary to avoid conflicts with the downlink resources for the sensing signal sent by base station A. At the same time, since the existing uplink resource scheduling configuration method in NR only supports continuous symbol-level configuration of "starting symbol + symbol length" in the time domain and does not support discontinuous configuration; in the frequency domain, it supports continuous (starting symbol + symbol length) and discontinuous (bitmap) frequency-domain resource configuration. Among them, the frequency-domain granularity of the discontinuous bitmap allocation is at the RBG level, and its size is related to the BWP size.

[0096] As Figure 2 shown, a transmission configuration method according to an embodiment of the present application is executed by a terminal and includes:

[0097] 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;

[0098] Step 202: Perform uplink transmission based on the first configuration information.

[0099] Here, the resource configuration for zero-power uplink transmission included in the first configuration information, that is, the first configuration information configures the resources for zero-power uplink transmission, or it can be understood that the first configuration information configures the resources not used for uplink transmission or the resources to be avoided.

[0100] In this way, after receiving the first configuration information sent by the first network device by executing step 201 and step 202, the terminal 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, so as to avoid conflicts between uplink transmission and sensing signals.

[0101] Among them, the terminal can determine candidate resources for uplink transmission. For example, when the first network device sends the third configuration information to the terminal, and the third configuration information includes the resource configuration for uplink transmission, at this time, the third configuration information indicates the candidate resources for uplink transmission. In this way, by combining the first configuration information, the terminal can know the target resources for uplink transmission, that is, the resources other than the zero-power uplink transmission resources among the candidate resources; further, the terminal performs uplink transmission on the target resources.

[0102] It should be noted that in this embodiment, performing uplink transmission based on the first configuration information means sending zero-power uplink transmission based on the first configuration information, or it can be understood as not performing uplink transmission on the zero-power uplink transmission resources configured by it based on the first configuration information. Among them, when sending zero-power uplink transmission, no sequence generation is required for zero-power uplink transmission.

[0103] Optionally, in this embodiment, the uplink transmission is a non-zero-power uplink transmission, which is a transmission sent by the terminal to the first network device and is an uplink communication between the terminal and the first network device. The uplink transmission includes the terminal sending uplink signals, uplink data, etc. to the first network device. Among them, the uplink signal can be an uplink reference signal. Correspondingly, sending zero-power uplink transmission can be sending zero-power uplink reference signals or zero-power uplink data.

[0104] Among them, the resource configuration for uplink transmission can be implemented through PUCCH scheduling information, PUSCH scheduling information, and uplink reference signal configuration information.

[0105] For example, as Figure 3 shown, 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 zero-power uplink reference signal ZP-RS) resources configured by the first configuration information are the resources circled by the dotted line in the figure. Then the terminal sends ZP-RS in the resources circled by the dotted line in the figure, or it can be understood as sending RS on the resources in the shaded area except for the area circled by the dotted line.

[0106] Optionally, the resources indicated by the first configuration information are related to the configuration parameters of the sensing signals sent by the second network device.

[0107] Here, the sensing signal is also called a sensing reference signal or a cooperative sensing signal.

[0108] In this embodiment, the second network device sends a sensing signal, and the first network device receives the reflected signal of the sensing signal, which is also referred to as an echo signal or a sensing echo signal. The resource indicated by the first configuration information, that is, the resource for zero-power uplink transmission configured by the first configuration information, is also referred to as a zero-power uplink transmission resource. The configuration parameters of the sensing signal sent by the second network device are parameters that can determine the echo signal resource of the sensing signal. Therefore, the resource indicated by the first configuration information is related to the configuration parameters of the sensing signal sent by the second network device. It can be understood that the zero-power uplink transmission resource is the same as the echo signal resource, or the zero-power uplink transmission resource includes the echo signal resource.

[0109] Specifically, as Figure 4 shown, the second network device is Base Station 1, and the first network device is Base Station 2. Base Station 1 sends a sensing signal such as SS1, and Base Station 2 receives the sensing echo signal from the detection target. At the same time, Base Station 2 also provides services for the terminal (UE) 1-2. Assume that Base Station 2 sends the resource for zero-power uplink transmission configured by the first configuration information to UE1 and sends the resource for zero-power uplink transmission configured by the first configuration information to UE2, and this resource is the same as the transmission resource of the sensing echo signal. Then UE1 and UE2 will not perform uplink transmission on the resource for zero-power uplink transmission. That is, UE1 sends ZP-RS1 on the resource for zero-power uplink transmission, and UE1 sends ZP-RS2 on the resource for zero-power uplink transmission.

[0110] Therefore, in the cooperative sensing networking scenario, the first network device sends the first configuration information to construct 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, avoiding conflicts between the reflected signal of the sensing signal and the uplink transmission.

[0111] Optionally, in this embodiment, the receiving the first configuration information sent by the first network device includes:

[0112] Receiving the first configuration information sent by the first network device when there is a conflict between the uplink transmission of the terminal and the transmission of the sensing signal.

[0113] That is, when the first network device determines that there is a conflict between the uplink transmission of the terminal and the transmission of the sensing signal, it sends the first configuration information to the terminal to notify the terminal not to perform uplink transmission on the transmission resource of the sensing signal, avoiding conflicts between transmissions.

[0114] Here, the conflict between the uplink transmission and the transmission of the sensing signal can also be understood as the conflict between the uplink transmission and the transmission of the sensing echo signal.

[0115] Optionally, the first network device obtains second configuration information, where the second configuration information includes the resource configuration of the sensing signal. The first network device can also obtain the resource configuration of the terminal's uplink transmission by obtaining third configuration information. In this way, based on the second configuration information and the third configuration information, the first network device can determine whether there is a conflict between the terminal's uplink transmission and the transmission of the sensing signal.

[0116] Specifically, the first network device obtains the second configuration information from the second network device or the sensing server.

[0117] In this embodiment, the resource configuration of the sensing signal includes, but is not limited to, one or more of the sensing signal ID, the time-frequency position of the sensing resource, the transmission period, etc. For example, the CSI-RS signal is reused to complete the sensing task, and its time-frequency position of the sensing resource includes, but is not limited to, the starting symbol in the time domain, the number of symbols, and in the frequency domain, the starting PRB, the number of PRBs, the bitmap configuration, the time domain comb, the frequency domain comb, etc. Among them, 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 CSI configuration (CSI-MeasConfig) of the serving cell configuration (ServingCellConfig).

[0118] Of course, if there is no conflict between the uplink transmission and the transmission of the sensing signal, the first network device does not need to send the first configuration information to the terminal.

[0119] Optionally, receiving the first configuration information sent by the first network device includes:

[0120] Receiving the first configuration information sent by the first network device when the priority of the sensing communication is higher than the priority of the uplink communication.

[0121] That is, when the priority of the sensing communication is higher than the priority of the uplink communication, the first network device will send the first configuration information to the terminal to notify the terminal not to perform uplink transmission on the transmission resources of the sensing signal, ensuring the smooth progress of the sensing communication.

[0122] Specifically, the priority of the sensing communication and the priority of the uplink communication are predefined or configured in advance. In addition, when the priority of the sensing communication is higher than the priority of the uplink communication, even if it is determined that there is no conflict between the terminal's uplink transmission and the transmission of the sensing signal, the first network device can still send the first configuration information.

[0123] Of course, if the priority of the sensing communication is lower than the priority of the uplink communication, the first network device may not send the first configuration information to the terminal.

[0124] Optionally, in this embodiment, the first configuration information includes at least one of the following:

[0125] Resource indication information, which is used to indicate the resources for zero-power uplink transmission;

[0126] Resource type, which is the type of the resources for zero-power uplink transmission;

[0127] A first identifier, which is used to indicate the resource mapping pattern of the sensing signal.

[0128] That is, the first configuration information includes this resource indication information, and the terminal can determine the resources for zero-power uplink transmission according to the indication of this resource indication information. The first configuration information includes this resource type (resourceType), and the terminal can understand the specific type of the resources for zero-power uplink transmission from this resource type. The first configuration information includes this first identifier, and the terminal can learn the resource mapping pattern of the sensing signal from this first identifier.

[0129] Optionally, the resource indication information includes at least one of the following: ResourceSetToReleaseList, ResourceSetId, ResourceId, ResourceElementPattern;

[0130] The resource type includes at least one of the following: aperiodic, periodic, semi-static.

[0131] Optionally, the first configuration information further includes:

[0132] Resource usage, where the resource usage includes a first usage, or the first usage and a second usage;

[0133] Wherein, the first usage is used to indicate that the resources indicated by the first configuration information are used for zero-power uplink transmission.

[0134] Here, if the resource usage (usage) included in the first configuration information only includes the first usage, it can be considered that the implementation of this first configuration information is a dedicated configuration of the resources for zero-power uplink transmission; if the resource usage included in the first configuration information includes the first usage and the second usage, it can be considered that the implementation of this first configuration information is to reuse the second usage configuration for the configuration of the resources for zero-power uplink transmission. The second usage is other usages except for indicating the resources for zero-power uplink transmission.

[0135] For example, in Example 1, a dedicated configuration of zero-power uplink transmission resources, such as the implementation of zp-rs-Config configuration, is to add zp-rs-Config configuration in the RRC signaling uplink BWP (UplinkBWP) configuration. Specifically, the structure of the UplinkBWP configuration is as follows:

[0136]

[0137]

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

[0139] Another example is that in Example 2, the configuration of zero-power uplink transmission resources multiplexes the Sounding Reference Signal (SRS) configuration. A new usage is added to the SRS-ResourceSet information element (SRS-ResourceSet IE) in the SRS-Config of the RRC signaling plinkBWP configuration. The listed usages include the first usage and the second usage. The first usage is such as cooperative sensing; the second usage is such as beam management, codebook, nonCodebook, antenna switching, 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]

[0141] In this way, in the SRS-Config, when usage = "cooperative sensing", resources associated with the resources of the cooperative sensing signal NZP-SS (SS1) are configured to avoid interference between the sensed echo signal and uplink transmission.

[0142] For the method of Example 2, new patterns may be added subsequently according to communication and sensing requirements.

[0143] Additionally, optionally, in this embodiment, the first identifier is a global identifier associated with the resource mapping pattern of the sensing signal, or a local identifier associated with the resource mapping pattern of the sensing signal in the first network device.

[0144] Here, the first identifier of the first configuration information may be the NZP-SSID in the above Example 1 or 2.

[0145] It should be noted that the identifier associated with the resource mapping pattern of the sensing signal known to the first network device may be informed by the second network device. If the identifier associated with the resource mapping pattern of the sensing signal informed by the second network device, that is, the second identifier, is its local identifier, there will be a situation where the terminal cannot recognize it. Therefore, the first network device will convert the second identifier into a global identifier or a local identifier of the first network device and carry it in the first configuration information to send to the terminal. Of course, if the second identifier informed by the second network device to the first network device is a global identifier, there is no need for further conversion, and the second identifier is directly carried in the first configuration information and sent to the terminal.

[0146] In summary, in the transmission configuration method of the embodiments of the present application, the terminal receives the first configuration information including the resource configuration of zero-power uplink transmission sent by the first network device and performs uplink transmission based on the first configuration information, avoiding the conflict between the reflected signal of the sensing signal and the uplink transmission, and thus avoiding the failure of the sensing task. Without changing the resource configuration method of PUSCH and PUCCH, by standardizing the resource conflict avoidance behavior of the UE, the UE can obtain the resources for realizing the sensing function, having a certain forward compatibility.

[0147] As Figure 5 shown, a transmission configuration method of the embodiments of the present application is executed by a first network device and includes:

[0148] Step 501, send first configuration information to the terminal, where the first configuration information includes the resource configuration of zero-power uplink transmission.

[0149] 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 sensing signal and the uplink transmission, and thus avoiding the failure of the sensing task.

[0150] Optionally, the resources indicated by the first configuration information are associated with the sensing signal sent by the second network device.

[0151] Optionally, before sending the first configuration information to the terminal, it includes:

[0153] Determine whether there is a conflict between the uplink transmission and the transmission of the sensing signal according to the second configuration information and the third configuration information;

[0155] In the case of a conflict, send the first configuration information to the terminal corresponding to the conflict.
