With the increase of detection requirements, if radar is used alone for detection with a wider coverage, the cost of radar equipment is higher, and in the case of continuous coverage, the interference between radars is large, which cannot meet the detection requirements. Considering that wireless communication has the advantages of rich spectrum resources, large deployment scale and wide coverage, radar sensing and wireless communication can be integrated to meet the needs of wireless communication and detection. Therefore, the integration of communication perception combined with radar detection and wireless network communication is the development trend of future communication.

当前，对于空中、地面交通监测、气象探测、安全监控、电磁成像等，雷达被广泛应用于其中。例如，在地面交通监测中，雷达可用于车辆测速，监测应急车道占用，违规变道等情况。在对空探测中，其可用于无人机监测等。随着探测需求的增加，如果单独用雷达进行覆盖范围较广的探测，设备成本较高，且在连续覆盖的情况下，雷达间干扰较大，无法满足探测需求。由于无线通信***，如4G LTE/5G NR的蜂窝网络，不仅拥有丰富的频谱资源，还具有部署规模大和覆盖广的优势。因此结合雷达探测和无线网络通信的优点，将二者进行一体化设计是一个重要的发展趋势。在该***中，基站可通过接收所发送感知信号的回波信号来感知目标，并估计出被感知目标的速度，距离，运动轨迹，形状、大小等。然而，例如在图2所示的场景中，对于路口、高速公路场景，基站在进行扫描过程中，邻区基站的直达径和强反射径会对车辆、行人和道路设施等目标的精确检测(包括探测距离，速度估计精度等)造成干扰。At present, radar is widely used in air and ground traffic monitoring, weather detection, security monitoring, electromagnetic imaging, etc. For example, in ground traffic monitoring, radar can be used to measure vehicle speed, monitor emergency lane occupancy, illegal lane changes, etc. In air detection, it can be used for UAV monitoring and so on. With the increase of detection requirements, if the radar is used alone for detection with a wider coverage, the equipment cost is high, and in the case of continuous coverage, the interference between radars is large, which cannot meet the detection requirements. Because wireless communication systems, such as 4G LTE/5G NR cellular networks, not only have abundant spectrum resources, but also have the advantages of large deployment scale and wide coverage. Therefore, combining the advantages of radar detection and wireless network communication, it is an important development trend to integrate the two. In this system, the base station can sense the target by receiving the echo signal of the sent sensing signal, and estimate the speed, distance, movement trajectory, shape, size, etc. of the sensed target. However, for example, in the scene shown in Figure 2, for intersections and highway scenes, during the scanning process of the base station, the direct path and strong reflection path of the neighboring cell base station will accurately detect objects such as vehicles, pedestrians, and road facilities ( Including detection distance, speed estimation accuracy, etc.) causing interference.
评估雷达***效能的一个重要指标为雷达检测概率，其随经过雷达处理后信噪比(post-signal to noise ratio，post-SNR)的变化而变化，例如图3所示的曲线，该曲线中， 目标检测概率从0到1变化，对应的post-SNR的变化范围仅有13dB。因此进一步说明了，雷达检测概率对post-SNR变化的敏感性较高，邻站干扰会导致雷达目标检测的精度降低，从而影响雷达的探测距离及通信感知一体化***的可靠性。An important indicator for evaluating the effectiveness of a radar system is the radar detection probability, which changes with the post-signal to noise ratio (post-SNR) after radar processing, such as the curve shown in Figure 3, in which , the target detection probability varies from 0 to 1, and the corresponding post-SNR variation range is only 13dB. Therefore, it is further explained that the radar detection probability is highly sensitive to post-SNR changes, and the interference of adjacent stations will lead to a decrease in the accuracy of radar target detection, thereby affecting the detection range of the radar and the reliability of the integrated communication perception system.
当前，在LTE***中，两个网络设备之间通过X2接口相互传输负载和干扰协调信息，其中，X2接口是e-NodeB之间的接口，支持数据和信令的直接传输。进一步地，在NR***中，gNB之间通过Xn接口实现相互连接。Currently, in the LTE system, two network devices transmit load and interference coordination information to each other through an X2 interface, where the X2 interface is an interface between e-NodeBs and supports direct transmission of data and signaling. Further, in the NR system, the gNBs are connected to each other through the Xn interface.
以LTE***的站间干扰协调技术为例，如图4所示，第一网络设备通过X2接口向邻区的第二网络设备发送负载信息发起该流程。Taking the inter-site interference coordination technology of the LTE system as an example, as shown in FIG. 4 , the first network device sends load information to the second network device in the neighboring cell through the X2 interface to initiate the process.
具体地，在图4中，若第二网络设备在负载信息中接收到上行干扰过载指示(up linkinterference overload indication)的信元(information element，IE)时，该信元用于指示小区在每个物理资源块(physical resource block，PRB)上所受的干扰水平。如表1所示，干扰水平可以包括高干扰、中干扰和低干扰三个等级。第二网络设备作为接收的网络设备可以基于这些信息设置其相应的调度策略，并且在接收到携带相同IE的新的干扰指示之前，第二网络设备认为接收到上行干扰过载指示IE值一直有效。Specifically, in FIG. 4, if the second network device receives an information element (information element, IE) of an uplink interference overload indication (up link interference overload indication) in the load information, the information element is used to indicate that the cell is in each The level of interference received on a physical resource block (physical resource block, PRB). As shown in Table 1, the interference level may include three levels of high interference, medium interference and low interference. The second network device as the receiving network device can set its corresponding scheduling policy based on these information, and before receiving a new interference indication carrying the same IE, the second network device considers that the received uplink interference overload indication IE value is always valid.

在一个示例中，例如，当第二网络设备在负载信息中收到上行高干扰指示信元(UL High Interference Indication(HII)IE)时，该信元用于指示从第一网络设备看去的每个PRB对应的高干扰灵敏度。例如下表2所示，HII IE通过位图(bitmap)的形式进行指示，位图的每个位置表示一个PRB对应的干扰灵敏度等级，其中“1”表示高干扰灵敏度，“0”表示“低干扰灵敏度”。In an example, for example, when the second network device receives an uplink high interference indication information element (UL High Interference Indication (HII) IE) in the load information, the information element is used to indicate the High interference sensitivity corresponding to each PRB. For example, as shown in Table 2 below, the HII IE is indicated in the form of a bitmap, and each position of the bitmap represents the interference sensitivity level corresponding to a PRB, where "1" indicates high interference sensitivity, and "0" indicates "low interference sensitivity".

应理解，第二网络设备应尽量避免将位于其小区边缘的UE调度到干扰灵敏度高的PRB上。在负载信息中的上行高干扰指示IE组中接收的目标小区标识信元(Target Cell ID IE)指示对应的上行高干扰的小区。同样地，第二网络设备应在接收到携带相同IE的新的干扰指示之前，认为上行高干扰信息指示的值一直有效。It should be understood that the second network device should try to avoid scheduling the UE located at the edge of its cell on the PRB with high interference sensitivity. The target cell identification information element (Target Cell ID IE) received in the uplink high interference indication IE group in the load information indicates the corresponding high uplink interference cell. Likewise, the second network device should consider the value indicated by the uplink high interference information to be valid until it receives a new interference indication carrying the same IE.
在通信感知一体化的场景中，由于车联网具有高动态、高安全、高实时等特性，为了实现自动驾驶的安全性，雷达检测对感知目标及路况信息采集的时效性和可靠性提出了更高的要求。此外，对于通信信号而言，虽然链路中干扰对接收信号质量的影响可通过链路自适应或重传等方式进行抑制，但是雷达目标检测具有实时性，即基站需要在极短的时间内通过接收回波实现对检测目标速度、距离、轨迹和形状大小等的有效估计，考虑到目标检测概率对接收SINR变化的敏感性高，为了提高目标检测的精度和通信感知一体化***的可靠性，基站间感知信号的干扰协调变得尤为重要。然而，当前站间干扰协调通过X2接口或者Xn接***互的信令无法满足对目标感知精度的需求。In the scenario of integrated communication and perception, due to the high dynamic, high security, and high real-time characteristics of the Internet of Vehicles, in order to realize the safety of automatic driving, radar detection puts forward more requirements for the timeliness and reliability of sensing targets and road condition information collection. high demands. In addition, for communication signals, although the impact of interference in the link on the quality of received signals can be suppressed through link adaptation or retransmission, radar target detection is real-time, that is, the base station needs to The effective estimation of the speed, distance, trajectory and shape of the detected target is realized by receiving the echo. Considering the high sensitivity of the target detection probability to the change of the received SINR, in order to improve the accuracy of target detection and the reliability of the integrated communication perception system , the interference coordination of sensing signals between base stations becomes particularly important. However, the current inter-station interference coordination signaling exchanged through the X2 interface or the Xn interface cannot meet the requirement for target perception accuracy.
因此，本申请提出了一种多站间感知信号的干扰协调方法，可以解决雷达扫描过程中，邻区基站对雷达目标检测干扰的影响。Therefore, the present application proposes a method for coordinating interference of sensing signals between multiple stations, which can solve the influence of the interference of neighboring cell base stations on radar target detection during the radar scanning process.
在通信、雷达一体化的***中，基站可通过接收所发送感知信号的回波信号来感知目标，并估计出被感知目标的速度，距离，运动轨迹，形状、大小等。用于目标检测的雷达扫描波束需要承载于感知信号上进行发送，基站在发送感知信号时，需要扫描小区内的多个波束方向，同时，一个扫描波束可能需要占用一个或多个时域符号或时隙。需要注意的是，雷达扫描波束所占用的时域符号为感知信号所占用的符号，并不是一个时隙中所有的符号。以图5所示的感知信号的时频资源配置图案为例，可以看出，基站按照波束1-波束4的顺序进行感知波束扫描，其中波束1，波束2，波束3以及波束4为配置的波束索引(beam ID)，不同的波束索引可以表示不同的感知扫描方向，且每个感知扫描波束时域占用一个OFDM符号，频域上采用梳状(comb)形式进行传输。In a communication and radar integrated system, the base station can perceive the target by receiving the echo signal of the sent sensing signal, and estimate the speed, distance, trajectory, shape, size, etc. of the perceived target. The radar scanning beam used for target detection needs to be carried on the sensing signal for transmission. When the base station sends the sensing signal, it needs to scan multiple beam directions in the cell. At the same time, one scanning beam may need to occupy one or more time domain symbols or time slot. It should be noted that the time-domain symbols occupied by the radar scanning beam are the symbols occupied by the perception signal, not all the symbols in a time slot. Taking the time-frequency resource configuration pattern of the sensing signal shown in Figure 5 as an example, it can be seen that the base station scans the sensing beams in the order of beam 1-beam 4, where beam 1, beam 2, beam 3 and beam 4 are configured Beam index (beam ID), different beam indexes can represent different sensing scanning directions, and each sensing scanning beam occupies one OFDM symbol in the time domain, and is transmitted in the form of a comb in the frequency domain.

本申请实施例通过网络设备间交互用于雷达目标检测的信号的资源配置信息或者功率信息的方法，使得邻区基站能够根据该信息灵活配置感知信号的资源或功率信息，从而实现空域的干扰协调。In the embodiment of the present application, the resource configuration information or power information of the signal used for radar target detection is exchanged between network devices, so that the base station of the neighboring cell can flexibly configure the resource or power information of the sensing signal according to the information, so as to realize interference coordination in the airspace .
考虑到车联网场景下高移动性的特征及对目标检测高实时性的要求，邻区基站需要在较短的时间内确定感知波束扫描图案(pattern)，并且可以根据实际的场景实现感知资源的灵活配置与调整。例如，可以将雷达检测分为两个阶段，即波束训练阶段和实际感知扫描阶段，其中波束训练阶段用于确定基站间满足感知需求的感知扫描波束的对应关系。考虑到雷达扫描过程中由于目标的移动带来的检测误差，为了快速确定满足感知需求的感知资源信息，波束训练阶段的感知信号占用的时域资源可以小于真实扫描阶段的感知信号占用的时域资源，例如，该训练阶段的每个波束的扫描时间可以是1个OFDM的时间。Considering the characteristics of high mobility in the Internet of Vehicles scenario and the high real-time requirements for target detection, the neighboring cell base station needs to determine the sensing beam scanning pattern (pattern) in a short period of time, and can realize the sensing resource allocation according to the actual scene. Flexible configuration and adjustment. For example, radar detection can be divided into two phases, that is, the beam training phase and the actual sensing scanning phase, where the beam training phase is used to determine the corresponding relationship between the sensing scanning beams that meet the sensing requirements between base stations. Considering the detection error caused by the movement of the target during the radar scanning process, in order to quickly determine the sensing resource information that meets the sensing needs, the time domain resources occupied by the sensing signals in the beam training phase can be smaller than the time domain resources occupied by the sensing signals in the real scanning phase Resources, for example, the scanning time of each beam in the training phase may be one OFDM time.

For example, for the beam 1 of the first network device, if the second network device exceeds the maximum allowable receiving power of the second network device when scanning with beam 1-beam 4, it means that the beam 1 of the first network device is strong. If the beam is interfered with, the second network device may feed back corresponding beam index information to the first network device.
