Among them, the master node schedules the slave nodes to realize data transmission between nodes. Therefore, on a carrier (such as a channel with an SLB bandwidth of about 20MHz) or a channel (such as a channel with an SLE bandwidth of 1MHz/2MHz/4MHz) used by a G node, the G node can schedule time-frequency resources for the T node/G The wireless measurement signal transmission of the node realizes the ranging and positioning of T node/G node.

可理解，本申请可用于车载无线定位场景(例如PEPS)、室内测距定位/导航场景，也可以用于其它广域无线通信或局域无线通信场景，本申请对此不作限制。在本申请中，实现测距/测角/定位/感知具有类似的步骤，因而用“测距”术语指代“定位/测角/测距/感知”。It can be understood that this application can be used in vehicle wireless positioning scenarios (such as PEPS), indoor ranging positioning/navigation scenarios, and can also be used in other wide-area wireless communication or local area wireless communication scenarios, and this application does not limit this.

可选的，该标识信息可以包括但不限于节点的标识ID，地址，IP等信息，例如SLB的物理层ID。为了提高安全性，避免物理层ID的泄漏，G节点也可以为每个节点(G节点和T节点)设置一个测量ID，该测量ID和每个节点一一对应。具体的测量ID设置方法可以和节点的层二ID(layer2ID)或物理层ID一一对应。Optionally, the identification information may include but is not limited to the identification ID, address, IP and other information of the node, such as the physical layer ID of the SLB. In order to improve security and avoid the leakage of the physical layer ID, the G node can also set a measurement ID for each node (G node and T node), and the measurement ID corresponds to each node one-to-one. The specific measurement ID setting method can correspond to the layer 2 ID (layer2ID) or physical layer ID of the node one-to-one.

上述A个比特的顺序(例如从左至右)，与建立测量组时的节点出现顺序一一对应。在图4所示的测距组配置信令中，测距成员1～n分别对应上述A个比特(此时有A＝n)，其中测距成员1～n使用各自的标识ID进行区分，从而指示各个测距成员是否是被测量节点。The order of the above-mentioned A bits (for example, from left to right) corresponds to the order of node appearance when establishing the measurement group. In the ranging group configuration signaling shown in Figure 4, ranging members 1 to n respectively correspond to the above-mentioned A bits (A = n at this time), where ranging members 1 to n are distinguished by their respective identification IDs. Thereby indicating whether each ranging member is a measured node.

通过本申请实施例，不仅可以根据第一信息中的第一位图的各个比特的值，确定与该比特对应的节点为第一从节点或测量节点，从而决定是否要与该节点进行测量交互，还可以根据多个从节点的标识信息与第一位图的各个比特的对应关系，识别各个节点的身份，从而可以使得第一从节点在对应的信道资源上向各个测量节点发送测量帧以及接收来自各个测量节点的测量帧，使得各个测量节点在对应的信道资源上向第一从节点发送测量帧以及接收来自第一从节点的测量帧，实现对第一从节点的测距定位。Through the embodiments of this application, not only can the node corresponding to the bit be determined to be the first slave node or the measurement node based on the value of each bit of the first bit map in the first information, thereby deciding whether to perform measurement interaction with the node , the identity of each node can also be identified based on the corresponding relationship between the identification information of multiple slave nodes and each bit of the first bit map, so that the first slave node can send measurement frames to each measurement node on the corresponding channel resources. Receive measurement frames from each measurement node, so that each measurement node sends measurement frames to the first slave node on corresponding channel resources and receives measurement frames from the first slave node to implement ranging and positioning of the first slave node.

在一种可能的实施例中，上述第一信息还可以包括第二位图。In a possible embodiment, the above-mentioned first information may also include a second bitmap.

其中，第二位图包括B个比特，该B个比特与B个资源块一一对应，B为大于1的整数。资源块为测量所使用的时频资源信息。例如，SLB中，一个资源块表示为至少一个测量帧的时长和测量所使用的有效子载波的频域带宽，一个测量帧时长可以为一个无线帧的时长，而测量带宽可以为80MHz；SLE中，一个资源块表示为至少一个测量帧的时长和测量所使用的信道带宽(如1MHz/2MHz/4MHz)。Wherein, the second bitmap includes B bits, the B bits correspond to B resource blocks one-to-one, and B is an integer greater than 1. The resource block is the time-frequency resource information used for measurement. For example, in SLB, a resource block is represented by the duration of at least one measurement frame and the frequency domain bandwidth of the effective subcarrier used for measurement. The duration of a measurement frame can be the duration of a wireless frame, and the measurement bandwidth can be 80MHz; in SLE , a resource block is represented by the duration of at least one measurement frame and the channel bandwidth used for measurement (such as 1MHz/2MHz/4MHz).

该B个比特与B个资源块的一一对应关系，可以理解为，与B个比特中值为第一值的比特相对应的资源块用于第一从节点发送测量帧，与B个比特中值为第二值的比特相对应的资源块用于测量节点发送测量帧。The one-to-one correspondence between B bits and B resource blocks can be understood as: the resource block corresponding to the bit with the first value among the B bits is used for the first slave node to send the measurement frame, and the resource block corresponding to the B bits is The resource block corresponding to the bit whose median value is the second value is used by the measurement node to send the measurement frame.

示例性的，与上述B个比特中值为1的比特相对应的资源块用于第一从节点发送测量帧，表示该资源块为被测量节点发送测量帧所占用的资源，相应的，各个测量节点可以在该资源块上接收来自第一从节点发送的测量帧；与上述B个比特中值为0的比特相对应的资源块用于测量节点发送测量帧，表示该资源块为测量节点发送测量帧所占用的资源，相应的，第一从节点可以在该资源块上接收来自测量节点发送的测量帧。例如，当上述B个比特中有一段比特值为“010000”，其对应的资源块分别用于“测量节点、第一从节点、测量节点、测量节点、测量节点、测量节点”发送测量帧，上述第二从节点可以是多个测量节点中的任一个。For example, the resource block corresponding to the bit with a value of 1 among the above B bits is used for the first slave node to send the measurement frame, indicating that the resource block is the resource occupied by the measured node for sending the measurement frame. Correspondingly, each The measurement node can receive the measurement frame sent from the first slave node on this resource block; the resource block corresponding to the bit with a value of 0 among the above B bits is used by the measurement node to send the measurement frame, indicating that the resource block is a measurement node Resources occupied by sending measurement frames. Correspondingly, the first slave node can receive measurement frames sent from the measurement node on this resource block. For example, when one of the above B bits has a bit value of "010000", its corresponding resource blocks are used for "measuring node, first slave node, measuring node, measuring node, measuring node, measuring node" to send measurement frames, The above-mentioned second slave node may be any one of a plurality of measurement nodes.

通过本申请实施例，可以根据第二信息中的第二位图的B个比特与B个资源块的对应关系，指示第一从节点在与其对应的资源块上发送测量帧，以及指示测量节点在与其对应的资源块上发送测量帧，从而可以使得第一从节点和各个测量节点之间在相应的资源块上进行测量帧交互，实现对第一从节点的测距定位；并且可以避免被测量节点与被测量节点之间的测量交互，以及避免测量节点与测量节点之间的测量交互，提高了测量的灵活性，可以适用于更广的测量应用场景；还可以通过资源块的位置排列顺序决定第一从节点和各个测量节点发送测量帧的时间顺序，可以减小第一从节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔，从而有利于减小残留载波频率偏差(carrier frequency offset，CFO)对第一从节点和测量节点之间双向测量的影响，提高测量精度。Through the embodiment of the present application, according to the correspondence between B bits of the second bitmap and B resource blocks in the second information, the first slave node can be instructed to send the measurement frame on the resource block corresponding to it, and the measurement node can be instructed The measurement frame is sent on the corresponding resource block, so that the first slave node and each measurement node can interact with the measurement frame on the corresponding resource block to achieve ranging and positioning of the first slave node; and can avoid being The measurement interaction between the measuring node and the measured node, and the avoidance of the measurement interaction between the measuring node and the measuring node, improve the flexibility of measurement and can be applied to a wider range of measurement application scenarios; it can also be arranged by the position of the resource block The sequence determines the time sequence in which the measurement frames are sent by the first slave node and each measurement node, which can reduce the maximum frame interval between the measurement frame sent by the first slave node and the edge measurement frame sent by the measurement node, thereby helping to reduce the residual carrier frequency deviation. (carrier frequency offset, CFO) affects the bidirectional measurement between the first slave node and the measurement node to improve measurement accuracy.

对于第二信息，还可以使用测量组建立时G节点发送的配置消息来指示。例如，图4为一个G节点和多个T节点建立一个测量组时，G节点发送的配置消息。在组播测距中，该配置消息可承载第二信息，测距成员1～n的顺序，指示了一共有n个用于发送测距帧的资源，且测距成员1～n按照在消息中配置的顺序i(i＝1,2,…,n),分别在第i个资源中发送测距帧，从而为n个测距成员指示了一一对应的资源。通过在测距组建立时发送的配置消息来预先配置测距成员发送资源的指示方式，避免了测距组每次测量之前都进行配置发送资源的消息开销，提高了资源配置效率。For the second information, the configuration message sent by the G node when the measurement group is established can also be used to indicate. For example, Figure 4 shows the configuration message sent by the G node when a G node and multiple T nodes establish a measurement group. In multicast ranging, the configuration message can carry second information. The order of ranging members 1 to n indicates that there are n resources in total for sending ranging frames, and ranging members 1 to n are in accordance with the order in the message. In the configured sequence i (i=1,2,...,n), ranging frames are sent in the i-th resource respectively, thereby indicating one-to-one corresponding resources for n ranging members. The configuration message sent when the ranging group is established is used to pre-configure the instruction method for the sending resources of the ranging members, which avoids the message overhead of configuring the sending resources before each measurement of the ranging group, and improves the efficiency of resource configuration.

Among them, the ranging member may include a master node (G node) or may not include a master node (G node), and this embodiment of the present application does not limit this. Optionally, you can also use 1 bit to indicate whether the ranging group member contains a G node. If the value of this bit is 1, it indicates that the ranging group member contains a G node. If the value of this bit is 0, it indicates that the ranging group member contains a G node. The members of this ranging group do not include G nodes.

测距成员字段：与测距组成员个数n相对应，依次包含n个测距成员的标识信息(比如，包括但不限于T1节点的ID、T2节点的ID、T3节点的ID、Tn节点的ID、)，该标识信息可以包括但不限于节点的标识ID，地址IP等信息，例如，可以是节点的物理层ID或媒体接入层ID或测量标识等，本申请实施例对此不作限制。通过该测距成员标识信息字段，可以识别各个节点的身份，从而可以使得被测节点向各个测量节点发送测量帧以及接收来自各个测量节点的测量帧，使得各个测量节点向被测节点发送测量帧以及接收来自被测节点的测量帧，实现被测节点与测量节点的双向测量。可选地，G节点将自己的标识ID也携带在测距组成员字段中，从而指示G节点也是测距组的一个成员节点。Ranging member field: corresponds to the number n of ranging group members, and contains the identification information of n ranging members in turn (for example, including but not limited to the ID of the T1 node, the ID of the T2 node, the ID of the T3 node, and the Tn node ID,), the identification information may include but is not limited to the identification ID of the node, address IP and other information, for example, it may be the physical layer ID or media access layer ID or measurement identification of the node, etc., the embodiment of this application does not do this. limit. Through the ranging member identification information field, the identity of each node can be identified, so that the measured node can send measurement frames to each measuring node and receive measurement frames from each measuring node, so that each measuring node can send measurement frames to the measured node. and receiving measurement frames from the node under test to implement bidirectional measurement between the node under test and the measurement node. Optionally, the G node also carries its own identification ID in the ranging group member field, thereby indicating that the G node is also a member node of the ranging group.

第一位图字段：用于指示节点位图。节点位图是一个包含n个比特的位图，用于指示测量组各个成员节点的节点身份是被测节点还是测量节点，即按照节点位图的比特顺序(从高比特位到低比特位，或者从低比特位到高比特位)，每个比特与一个测距成员一一对应。如果节点位图中的一个比特设置为1，则表示该比特对应的测距成员为被测量节点(即上述第一从节点)；如果节点位图中的一个比特设置为0，表示该测距成员不是被测量节点，而是测量节点(即上述第二从节点和/或主节点)。通过该第一位图字段，各个节点即可在测距初始化时，知晓测量节点与被测节点的关系，从而决定是否要与对方节点进行测量交互，保障测量节点(包括主节点和/或第二从节点)都可以在被测节点(第一从节点)的资源上接收被测节点发送的测量帧，以及被测节点都可以在测量节点的资源上接收测量节点发送的测量帧，实现被测节点与测量节点的双向测量。并且可以避免被测量节点与被测量节点之间的测量交互，以及避免测量节点与测量节点之间的测量交互，提高了测量的灵活性，可以适用于更广的测量应用场景。The first bitmap field: used to indicate the node bitmap. The node bitmap is a bitmap containing n bits, which is used to indicate whether the node identity of each member node of the measurement group is the measured node or the measuring node, that is, according to the bit order of the node bitmap (from high bit to low bit, Or from low bit to high bit), each bit corresponds to a ranging member one-to-one. If a bit in the node bitmap is set to 1, it means that the ranging member corresponding to the bit is the measured node (i.e., the first slave node mentioned above); if a bit in the node bitmap is set to 0, it means that the ranging member The member is not the measured node, but the measuring node (ie the above-mentioned second slave node and/or master node). Through the first map field, each node can know the relationship between the measuring node and the measured node during ranging initialization, thereby deciding whether to conduct measurement interaction with the other node to ensure that the measuring node (including the main node and/or the third node) The two slave nodes) can both receive the measurement frame sent by the node under test (the first slave node) on the resources of the node being tested (the first slave node), and the node under test can receive the measurement frame sent by the measuring node on the resources of the measuring node. Two-way measurement between measurement nodes. And it can avoid the measurement interaction between the measured node and the measured node, and avoid the measurement interaction between the measuring node and the measuring node, which improves the flexibility of measurement and can be applied to a wider range of measurement application scenarios.

第二位图字段：用于指示资源块位图。资源块位图是一个包含B个比特的位图(B大于或等于n)，按照顺序，每个比特与一个用于传输测量帧的资源块一一对应。如果资源块位图中的一个比特设置为1，则表示该比特对应的资源块为被测量节点(即上述第一从节点)发送测量帧所占用的资源，用于被测量节点(即上述第一从节点)发送测量帧，相应的，各个测量节点可以在该资源块上接收来自被测量节点(即上述第一从节点)发送的测量帧；如果资源块位图中的一个比特设置为0，则表示该比特对应的资源块为测量节点(即上述第二从节点和/或主节点)发送测量帧所占用的资源，用于测量节点(即上述第二从节点和/或主节点)发送测量帧，相应的，被测量节点(即上述第一从节点)可以在该资源块上接收来自测量节点(即上述第二从节点和/或主节点)发送的测量帧。通过该第二位图字段，各个节点即可在测距初始化时，知晓各个资源块与测量节点和被测节点的关系，使得被测量节点在与其对应的资源块上发送测量帧，以及测量节点在与其对应的资源块上发送测量帧，从而可以使得被测量节点和各个测量节点之间在相应的资源块上进行双向测量，实现对被测量节点的测距定位。上述双向测量在基于飞行时间的测距和基于跳频合并带宽的测距中是必要的测量步骤，可以获得高准确度的测距结果。而主节点向多个从节点指示第二位图信息，可以避免被测量节点与被测量节点之间的测量交互，以及避免测量节点与测量节点之间的测量交互，避免了多个节点之间的测量开销，提高了测量的灵活性，可以适用于更广的测量应用场景。还可以通过资源块的位置排列顺序决定被测量节点和各个测量节点发送测量帧的时间顺序，可以减小被测量节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔，从而有利于减小残留载波频率偏差CFO对被测量节点和测量节点之间双向测量的影响，提高测量精度。Second bitmap field: used to indicate the resource block bitmap. The resource block bitmap is a bitmap containing B bits (B is greater than or equal to n). In order, each bit corresponds to a resource block used to transmit the measurement frame. If a bit in the resource block bitmap is set to 1, it means that the resource block corresponding to the bit is the resource occupied by the measured node (i.e., the above-mentioned first slave node) for sending the measurement frame, and is used for the measured node (i.e., the above-mentioned first slave node). A slave node) sends a measurement frame. Correspondingly, each measuring node can receive a measurement frame sent from the measured node (ie, the above-mentioned first slave node) on the resource block; if a bit in the resource block bitmap is set to 0 , it means that the resource block corresponding to this bit is the resource occupied by the measuring node (ie, the above-mentioned second slave node and/or master node) to send the measurement frame, and is used for the measuring node (ie, the above-mentioned second slave node and/or master node) The measurement frame is sent, and accordingly, the measured node (ie, the above-mentioned first slave node) can receive the measurement frame sent from the measuring node (ie, the above-mentioned second slave node and/or the master node) on the resource block. Through the second bitmap field, each node can know the relationship between each resource block and the measuring node and the measured node during ranging initialization, so that the measured node sends a measurement frame on its corresponding resource block, and the measuring node The measurement frame is sent on the corresponding resource block, so that bidirectional measurement can be performed between the measured node and each measuring node on the corresponding resource block, thereby achieving ranging and positioning of the measured node. The above-mentioned two-way measurement is a necessary measurement step in ranging based on time of flight and ranging based on frequency hopping combined bandwidth, and high-accuracy ranging results can be obtained. The master node indicates the second bitmap information to multiple slave nodes, which can avoid the measurement interaction between the measured node and the measured node, avoid the measurement interaction between the measuring node and the measuring node, and avoid the measurement interaction between multiple nodes. The measurement overhead is reduced, which improves the flexibility of measurement and can be applied to a wider range of measurement application scenarios. The time sequence of sending measurement frames by the measured node and each measuring node can also be determined by the position arrangement order of the resource blocks, which can reduce the maximum frame interval between the measurement frame sent by the measured node and the edge measurement frame sent by the measuring node, which is beneficial to Reduce the impact of the residual carrier frequency deviation CFO on the two-way measurement between the measured node and the measuring node, and improve the measurement accuracy.

除了上述字段，上述消息还可以包括本次测量的会话标识符(Dialogue Token)或业务编号(Transaction ID)，用于识别在一对节点之间进行的测量会话/测量业务。In addition to the above fields, the above message can also include the session identifier (Dialogue Token) or business number (Transaction ID) of this measurement, which is used to identify the measurement session/measurement business conducted between a pair of nodes.

可以理解的是，本申请实施例提供的报文中的测距成员字段可以对应于上述第一信息包括的通信域中的多个从节点和/或主节点的标识信息，第一位图字段可以对应于上述第一信息包括的第一位图，第二位图字段可以对应于上述第二信息包括的第二位图。It can be understood that the ranging member field in the message provided by the embodiment of the present application may correspond to the identification information of multiple slave nodes and/or master nodes in the communication domain included in the above-mentioned first information. The first map field The first bitmap field may correspond to the first bitmap included in the above-mentioned first information, and the second bitmap field may correspond to the second bitmap included in the above-mentioned second information.

The first information and the second information may also be transmitted through other reasonably deformed messages, such as addition or deletion of field content, etc., and the embodiments of the present application do not limit this.

可以理解的是，本申请实施例提供的报文中的各个字段的内容可以承载于一个报文上，也可以一个字段内容或多个字段内容分别承载于不同的报文上，本申请实施例对此不作限制。It can be understood that the contents of each field in the message provided by the embodiment of the present application can be carried in one message, or the content of one field or the contents of multiple fields can be carried in different messages respectively. The embodiment of the present application There are no restrictions on this.

在一种可能的实施例中，上述第二信息用于指示测量节点对第一从节点进行测量所占用的信道资源，该信道资源可能存在以下多种实现方式：In a possible embodiment, the above-mentioned second information is used to indicate the channel resources occupied by the measuring node for measuring the first slave node. The channel resources may be implemented in the following multiple ways:

方式一：method one:

方式一也称为组播测距/组测距。通信域包括第一从节点和对第一从节点执行测量的N个测量节点，相应的，通信信道资源包括相邻的N+1个资源块(相邻资源块之间可存在测量帧的帧间间隔)。 Method 1 is also called multicast ranging/group ranging. The communication domain includes a first slave node and N measurement nodes that perform measurements on the first slave node. Correspondingly, the communication channel resources include adjacent N+1 resource blocks (frames of measurement frames may exist between adjacent resource blocks). interval).

其中，N+1个资源块中的1个资源块用于第一从节点发送测量帧，N+1个资源块中的N个资源块分别用于N个测量节点发送测量帧。N+1个资源块依次被第一从节点和对第一从节点执行测量的N个测量节点依次发送测量帧；而对于第一从节点发送的测量帧，由于N个测量节点都会接收，因此可以理解为第一从节点向N个测量节点组播发送测量帧。Among them, one resource block among the N+1 resource blocks is used for the first slave node to send the measurement frame, and N resource blocks among the N+1 resource blocks are respectively used for the N measurement nodes to send the measurement frame. N+1 resource blocks are sequentially sent measurement frames by the first slave node and the N measurement nodes that perform measurements on the first slave node; and for the measurement frame sent by the first slave node, since all N measurement nodes will receive it, It can be understood that the first slave node multicasts the measurement frame to the N measurement nodes.

可以理解为，在一个组播测量帧交互中，第一从节点在N+1个资源块中的1个资源块上每发送一个测量帧，N个测量节点接收该测量帧后，会相应的在N个资源块中的某个资源块上各发送一个测量帧(即N个测量节点在N+1个资源块中的N个资源块上共发送N个测量帧)。上述组播测量帧交互为一次测量交互，为了提高测量信噪比(SNR)，可重复多次上述组播测量帧交互。重复次数由主节点在测量开始之前通过组播测量消息进行配置。It can be understood that in a multicast measurement frame interaction, each time the first slave node sends a measurement frame on 1 resource block among the N+1 resource blocks, the N measurement nodes will respond accordingly after receiving the measurement frame. One measurement frame is each sent on a certain resource block among the N resource blocks (that is, the N measurement nodes send a total of N measurement frames on N resource blocks among the N+1 resource blocks). The above-mentioned multicast measurement frame interaction is one measurement interaction. In order to improve the measurement signal-to-noise ratio (SNR), the above-mentioned multicast measurement frame interaction can be repeated multiple times. The number of repetitions is configured by the master node via a multicast measurement message before measurements start.

通过本申请实施例，基于组播的测量帧交互可以减少第一从节点发送的测量帧数量，在通信域的一次组播测量帧交互过程中，第一从节点只需要发送一个测量帧，提高了测量帧传输效率，有利于第一从节点节省功耗和节省发送资源。Through the embodiments of this application, multicast-based measurement frame interaction can reduce the number of measurement frames sent by the first slave node. During a multicast measurement frame interaction process in the communication domain, the first slave node only needs to send one measurement frame, improving In order to measure the frame transmission efficiency, it is beneficial to the first slave node to save power consumption and save sending resources.

可选的，如图4所示，测量组成员(即测距组成员)的顺序决定了各资源的顺序，而N+1个资源块的排列顺序与在该N+1个资源块上发送测量帧的时间顺序一一对应。主节点还可以通过配置N+1个节点的资源块的位置排列顺序，从而决定第一从节点和N个测量节点发送测量帧的时间顺序。当N+1个资源块中用于第一从节点发送测量帧的一个资源块位于N+1个资源块的中间位置时，可以减小第一从节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔，从而有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。主节点配置N+1个节点的资源块时，可以向各个节点以单播方式或组播方式发送调度消息进行资源块配置。Optionally, as shown in Figure 4, the order of the measurement group members (i.e., the ranging group members) determines the order of each resource, and the order of the N+1 resource blocks is consistent with the order of the N+1 resource blocks. The time sequence of the measurement frames corresponds one to one. The master node can also determine the time sequence in which the first slave node and the N measurement nodes send measurement frames by configuring the position order of the resource blocks of the N+1 nodes. When one of the N+1 resource blocks used for the first slave node to send the measurement frame is located in the middle of the N+1 resource blocks, the edge between the measurement frame sent by the first slave node and the measurement node can be reduced. The maximum frame interval of the measurement frame is beneficial to reducing the impact of the residual carrier frequency deviation CFO on the two-way measurement between the first slave node and the measurement node, and improving the measurement accuracy. When the master node configures the resource blocks of N+1 nodes, it can send scheduling messages to each node in unicast or multicast mode to configure the resource blocks.

示例性的，上述第二信息指示的信道资源，还可参阅图5A，图5A为本申请实施例提供的一种信道资源示意图。Exemplarily, for the channel resources indicated by the above-mentioned second information, please refer to FIG. 5A. FIG. 5A is a schematic diagram of channel resources provided by an embodiment of the present application.

如图5A所示，上述N＝4，通信域包括第一从节点(T1节点)和对第一从节点执行测量的4个测量节点(G节点、T2节点、T3节点、T4节点)，相应的，信道资源包括相邻的(4+1)个资源块。As shown in Figure 5A, the above N=4, the communication domain includes the first slave node (T1 node) and four measurement nodes (G node, T2 node, T3 node, T4 node) that perform measurements on the first slave node. Correspondingly , the channel resource includes adjacent (4+1) resource blocks.

其中，相邻的(4+1)个资源块中的1个资源块用于第一从节点(T1节点)发送测量帧，相邻的(4+1)个资源块中的4个资源块分别用于4个测量节点(G节点、T2节点、T3节点、T4节点)发送测量帧。Among them, 1 resource block among the adjacent (4+1) resource blocks is used by the first slave node (T1 node) to send the measurement frame, and 4 resource blocks among the adjacent (4+1) resource blocks Used respectively for 4 measurement nodes (G node, T2 node, T3 node, T4 node) to send measurement frames.

可以理解为，在通信域的一次组播测量帧交互中，第一从节点(T1节点)在相邻的(4+1)个资源块中的1个资源块上每发送一个测量帧，4个测量节点(G节点、T2节点、T3节点、T4节点)接收该测量帧后，会相应的在相邻的(4+1)个资源块中的某个资源块上各发送一个测量帧(即4个测量节点在4+1个资源块中的4个资源块上共发送4个测量帧)，实现G-T1节点之间的测量帧交互，T1-T2节点之间的测量帧交互，T1-T3节点之间的测量帧交互，以及T1-T4节点之间的测量帧交互。It can be understood that in a multicast measurement frame interaction in the communication domain, each time the first slave node (T1 node) sends a measurement frame on 1 resource block among the adjacent (4+1) resource blocks, 4 After receiving the measurement frame, each measurement node (G node, T2 node, T3 node, T4 node) will correspondingly send a measurement frame on one of the adjacent (4+1) resource blocks ( That is, 4 measurement nodes send a total of 4 measurement frames on 4 resource blocks in 4+1 resource blocks) to realize measurement frame interaction between G-T1 nodes and measurement frame interaction between T1-T2 nodes. Measurement frame interaction between T1-T3 nodes, and measurement frame interaction between T1-T4 nodes.

此时，在通信域的一次组播测量帧交互中，第一从节点和测量节点发送测量帧的数量比例为1:4。基于组播的测量帧交互可以减少第一从节点发送的测量帧数量，在通信域的一次组播测量帧交互过程中，第一从节点只需要发送一个测量帧，提高了测量帧传输效率，有利于第一从节点节省功耗和节省发送资源。At this time, in a multicast measurement frame interaction in the communication domain, the ratio of the number of measurement frames sent by the first slave node and the measurement node is 1:4. Multicast-based measurement frame interaction can reduce the number of measurement frames sent by the first slave node. During a multicast measurement frame interaction process in the communication domain, the first slave node only needs to send one measurement frame, which improves the measurement frame transmission efficiency. It is beneficial to the first slave node to save power consumption and sending resources.

可选的，相邻的(4+1)个资源块的排列顺序与在该相邻的(4+1)个资源块上发送测量帧的时间顺序一一对应，还可以通过配置各节点资源块的位置排列顺序，决定第一从节点(T1节点)和各个测量节点(G节点、T2节点、T3节点、T4节点)发送测量帧的时间顺序。Optionally, the order of adjacent (4+1) resource blocks corresponds to the time sequence of sending measurement frames on the adjacent (4+1) resource blocks. You can also configure the resources of each node. The position order of the blocks determines the time sequence in which the first slave node (T1 node) and each measurement node (G node, T2 node, T3 node, T4 node) send measurement frames.

由于第一从节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔较大时，会导致残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，降低测量精度。Since the maximum frame interval between the measurement frame sent by the first slave node and the edge measurement frame sent by the measurement node is large, the residual carrier frequency deviation CFO will affect the bidirectional measurement between the first slave node and the measurement node, reducing the measurement accuracy. .

例如，假设G-T1节点之间的测量帧交互对应的帧间隔为2t，则：T1-T2节点之间的测量帧交互对应的帧间隔为2t，T1-T3节点之间的测量帧交互对应的帧间隔为3t，T1-T4节点之间的测量帧交互对应的帧间隔为4t。可以看出，T1-T4节点之间的测量帧交互对应的帧间隔(4t)远大于G-T1节点之间的测量帧交互对应的帧间隔(2t)，严重影响T1-T4节点之间的测量精度。For example, assuming that the frame interval corresponding to the measurement frame interaction between G-T1 nodes is 2t, then: the frame interval corresponding to the measurement frame interaction between T1-T2 nodes is 2t, and the measurement frame interaction between T1-T3 nodes corresponds to The frame interval is 3t, and the frame interval corresponding to the measurement frame interaction between T1-T4 nodes is 4t. It can be seen that the frame interval (4t) corresponding to the measurement frame interaction between T1-T4 nodes is much larger than the frame interval (2t) corresponding to the measurement frame interaction between G-T1 nodes, which seriously affects the communication between T1-T4 nodes. measurement accuracy.

此时，将用于第一从节点发送测量帧的资源块的位置调整为相邻的(4+1)个资源块的中间位置，即将用于第一从节点(T1节点)发送测量帧的资源块的位置与用于T2节点发送测量帧的资源块的位置对调，使得用于第一从节点发送测量帧的资源块的位置位于原先用于T2节点发送测量帧的资源块的位置。At this time, the position of the resource block used by the first slave node to send the measurement frame is adjusted to the middle position of the adjacent (4+1) resource blocks, that is, the position of the resource block used by the first slave node (T1 node) to send the measurement frame. The position of the resource block is swapped with the position of the resource block used by the T2 node to send the measurement frame, so that the position of the resource block used by the first slave node to send the measurement frame is located at the position of the resource block originally used by the T2 node to send the measurement frame.

调整后的帧间隔为：G-T1节点之间的测量帧交互对应的帧间隔为3t，T1-T2节点之间的测量帧交互对应的帧间隔为2t，T1-T3节点之间的测量帧交互对应的帧间隔为2t，T1-T4节点之间的测量帧交互对应的帧间隔为3t。The adjusted frame interval is: the frame interval corresponding to the measurement frame interaction between G-T1 nodes is 3t, the frame interval corresponding to the measurement frame interaction between T1-T2 nodes is 2t, and the measurement frame interval between T1-T3 nodes The frame interval corresponding to the interaction is 2t, and the frame interval corresponding to the measurement frame interaction between T1-T4 nodes is 3t.

可以看出，通过调整资源块的位置排列顺序，可以从整体上减小第一从节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔，有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。It can be seen that by adjusting the position and order of resource blocks, the maximum frame interval between the measurement frame sent by the first slave node and the edge measurement frame sent by the measuring node can be reduced as a whole, which is beneficial to reducing the residual carrier frequency deviation CFO pair The influence of bidirectional measurement between the first slave node and the measuring node improves the measurement accuracy.

方式二：Method two:

方式二也称为单播测距方式。通信域包括第一从节点和对第一从节点执行测量的N个测量节点，相应的，信道资源包括2N个资源块。 Method 2 is also called the unicast ranging method. The communication domain includes a first slave node and N measurement nodes that perform measurements on the first slave node. Correspondingly, the channel resources include 2N resource blocks.

其中，2N个资源块中的第2i个资源块用于第一从节点发送测量帧，2N个资源块中的第2i-1个资源块用于N个测量节点中的第i个测量节点发送测量帧。或者，2N个资源块中的第2i个资源块用于N个测量节点中的第i个测量节点发送测量帧，2N个资源块中的第2i-1个资源块用于第一从节点发送测量帧。Among them, the 2i-th resource block among the 2N resource blocks is used for the first slave node to send the measurement frame, and the 2i-1th resource block among the 2N resource blocks is used for the i-th measurement node among the N measurement nodes to send. Measurement frame. Alternatively, the 2i-th resource block among the 2N resource blocks is used for the i-th measurement node among the N measurement nodes to send the measurement frame, and the 2i-1th resource block among the 2N resource blocks is used for the first slave node to send Measurement frame.

可以理解为，在一个单播测量帧交互中，第一从节点在2N个资源块中的第2i个资源块(或2N个资源块中的第2i-1个资源块)上每发送一个测量帧，N个测量节点中的第i个测量节点会相应的在2N个资源块中的第2i-1个资源块(或2N个资源块中的第2i个资源块)上发送一个测量帧。It can be understood that in a unicast measurement frame interaction, the first slave node sends a measurement on the 2i-th resource block among the 2N resource blocks (or the 2i-1th resource block among the 2N resource blocks). frame, the i-th measurement node among the N measurement nodes will correspondingly send a measurement frame on the 2i-1th resource block among the 2N resource blocks (or the 2i-th resource block among the 2N resource blocks).

通过本申请实施例，基于单播的测量帧交互提高第一从节点发送测量帧的数量，可以进一步减小第一从节点发送的测量帧与测量节点发送的测量帧的帧间隔，有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。Through the embodiments of the present application, unicast-based measurement frame interaction increases the number of measurement frames sent by the first slave node, which can further reduce the frame interval between the measurement frames sent by the first slave node and the measurement frames sent by the measuring node, which is beneficial to reducing the number of measurement frames sent by the first slave node. The impact of small residual carrier frequency deviation CFO on the bidirectional measurement between the first slave node and the measuring node improves the measurement accuracy.

如图5B所示，上述N＝4，通信域包括第一从节点(T1节点)和对第一从节点执行测量的4个测量节点(G节点、T2节点、T3节点、T4节点)，相应的，通信信道资源包括(2×4)个资源块。As shown in Figure 5B, the above N=4, the communication domain includes the first slave node (T1 node) and four measurement nodes (G node, T2 node, T3 node, T4 node) that perform measurements on the first slave node. Correspondingly , the communication channel resource includes (2×4) resource blocks.

其中，(2×4)个资源块中的第2个资源块用于第一从节点(T1节点)发送测量帧，(2×4)个资源块中的第1个资源块用于4个测量节点中的第1个测量节点(G节点)发送测量帧，实现G-T1节点之间的测量帧交互。同理，(2×4)个资源块中的第4个资源块用于第一从节点(T1节点)发送测量帧，(2×4)个资源块中的第3个资源块用于4个测量节点中的第2个测量节点(T2节点)发送测量帧，实现T2-T1节点之间的测量帧交互；(2×4)个资源块中的第6个资源块用于第一从节点(T1节点)发送测量帧，(2×4)个资源块中的第5个资源块用于4个测量节点中的第3个测量节点(T3节点)发送测量帧，实现T3-T1节点之间的测量帧交互；(2×4)个资源块中的第8个资源块用于第一从节点(T1节点)发送测量帧，(2×4)个资源块中的第7个资源块用于4个测量节点中的第4个测量节点(T4节点) 发送测量帧，实现T4-T1节点之间的测量帧交互。Among them, the second resource block among (2×4) resource blocks is used for the first slave node (T1 node) to send the measurement frame, and the first resource block among (2×4) resource blocks is used for 4 The first measurement node (G node) among the measurement nodes sends a measurement frame to realize measurement frame interaction between G-T1 nodes. Similarly, the 4th resource block among (2×4) resource blocks is used for the first slave node (T1 node) to send the measurement frame, and the 3rd resource block among (2×4) resource blocks is used for 4 The second measurement node (T2 node) among the measurement nodes sends the measurement frame to realize the measurement frame interaction between the T2-T1 nodes; the sixth resource block among the (2×4) resource blocks is used for the first slave The node (T1 node) sends the measurement frame, and the 5th resource block among the (2×4) resource blocks is used for the 3rd measurement node (T3 node) among the 4 measurement nodes to send the measurement frame to realize the T3-T1 node. Measurement frame interaction between them; the 8th resource block among (2×4) resource blocks is used for the first slave node (T1 node) to send the measurement frame, and the 7th resource among (2×4) resource blocks The block is used by the fourth measurement node (T4 node) among the four measurement nodes to send measurement frames to realize measurement frame interaction between T4-T1 nodes.

可以理解为，在通信域的一次单播测量帧交互中，第一从节点在(2×4)个资源块中的第2i个资源块(或(2×4)个资源块中的第2i-1个资源块)上每发送一个测量帧时，4个测量节点中的第i个测量节点会相应的在(2×4)个资源块中的第2i-1个资源块(或(2×4)个资源块中的第2i个资源块)上发送一个测量帧。It can be understood that in a unicast measurement frame interaction in the communication domain, the first slave node is in the 2i-th resource block among (2×4) resource blocks (or the 2i-th resource block among (2×4) resource blocks). -1 resource block), the i-th measurement node among the 4 measurement nodes will correspondingly transmit a measurement frame on the 2i-1th resource block (or (2 A measurement frame is sent on the 2ith resource block) among ×4) resource blocks.

如果G节点是测量节点且G节点需要发送前导信号，则G节点发送完测距帧后，被测节点再发送测距帧。如图5B所示，在测量节点和被测节点的成对测距帧交互中，被测节点位于成对资源中的第二个进行发送。这有利于G节点发送完前导信号之后立即发送测量帧，减少G节点与被测节点的切换时间。If the G node is a measuring node and the G node needs to send a preamble signal, after the G node sends the ranging frame, the measured node sends the ranging frame again. As shown in Figure 5B, in the pairwise ranging frame interaction between the measuring node and the measured node, the measured node is located in the second one of the paired resources and sends. This is conducive to the G node sending the measurement frame immediately after sending the preamble signal, reducing the switching time between the G node and the node under test.

或者，G节点向被测节点发送一个指示信息，用于指示被测节点在测距交互中，使用第一个测距帧的发送资源，或者使用第二个测距帧的发送资源；也即，上述指示信息指示被测节点占用测距交互中的前一个资源或后一个资源。Alternatively, the G node sends an instruction message to the measured node to instruct the measured node to use the sending resources of the first ranging frame or to use the sending resources of the second ranging frame in the ranging interaction; that is, , the above indication information indicates that the measured node occupies the previous resource or the next resource in the ranging interaction.

此时，在通信域的一次单播测量帧交互中，第一从节点和测量节点发送测量帧的数量比例为4:4。与上述图5A所示的组播测量帧相比，图5B中基于单播的测量帧交互可以通过提高第一从节点发送测量帧的数量，来进一步减小第一从节点发送的测量帧与测量节点发送的测量帧的帧间隔，有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。At this time, in a unicast measurement frame interaction in the communication domain, the ratio of the number of measurement frames sent by the first slave node and the measurement node is 4:4. Compared with the multicast measurement frame shown in Figure 5A above, the unicast-based measurement frame interaction in Figure 5B can further reduce the number of measurement frames sent by the first slave node by increasing the number of measurement frames sent by the first slave node. The frame interval of the measurement frames sent by the measurement node is conducive to reducing the impact of the residual carrier frequency deviation CFO on the two-way measurement between the first slave node and the measurement node, and improving the measurement accuracy.

方式三：Method three:

通信域至少包括一组第一从节点和对第一从节点执行测量的M×L个测量节点，相应的，信道资源包括(M+1)×L个资源块。The communication domain at least includes a group of first slave nodes and M×L measurement nodes that perform measurements on the first slave nodes. Correspondingly, the channel resources include (M+1)×L resource blocks.

其中，(M+1)×L个资源块中的L个资源块用于第一从节点发送测量帧，(M+1)×L个资源块中其余的M×L个资源块用于M×L个测量节点发送测量帧，并且在(M+1)×L个资源块中，L个资源块中的任一个资源块与M×L个资源块中的M个资源块组成相邻的1+M个资源块。Among them, L resource blocks among the (M+1)×L resource blocks are used for the first slave node to send the measurement frame, and the remaining M×L resource blocks among the (M+1)×L resource blocks are used for M ×L measurement nodes send measurement frames, and among the (M+1)×L resource blocks, any one of the L resource blocks and M resource blocks among the M×L resource blocks form adjacent 1+M resource blocks.

可以理解为，在一个组播测量帧交互中，第一从节点在L个资源块中的任一个资源块上每发送一个测量帧，M×L个测量节点中的M个测量节点接收该测量帧后，会相应的在M×L个资源块中的M个资源块上各发送一个测量帧(即M×L个测量节点中的M个测量节点在M×L个资源块中的M个资源块上共发送M个测量帧)。It can be understood that in a multicast measurement frame interaction, each time the first slave node sends a measurement frame on any one of the L resource blocks, M measurement nodes among the M×L measurement nodes receive the measurement. After the frame, a measurement frame will be sent correspondingly on M resource blocks among the M×L resource blocks (that is, the M measurement nodes among the M×L measurement nodes are on the M A total of M measurement frames are sent on the resource block).

通过本申请实施例，基于组播的测量帧交互适当提高第一从节点发送的测量帧数量，可以在保障测量帧传输效率以及第一从节点节省功耗和节省发送资源的同时，减小第一从节点发送的测量帧与测量节点发送的测量帧的帧间隔，有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。Through the embodiments of this application, the multicast-based measurement frame interaction appropriately increases the number of measurement frames sent by the first slave node, which can ensure the transmission efficiency of the measurement frames and save power consumption and transmission resources of the first slave node while reducing the number of measurement frames sent by the first slave node. The frame interval between the measurement frame sent by the first slave node and the measurement frame sent by the measurement node is beneficial to reducing the impact of the residual carrier frequency deviation CFO on the bidirectional measurement between the first slave node and the measurement node, and improving measurement accuracy.

可选的，上述相邻的1+M个资源块的排列顺序与第一从节点和M个测量节点在该1+M个资源块上发送测量帧的时间顺序一一对应，还可以通过主节点发送第二位图和/或调度信息，确定第一从节点和各个测量节点的资源块，即确定发送测量帧的时间顺序。当上述相邻的1+M个资源块中用于第一从节点发送测量帧的一个资源块位于1+M个资源块的中间位置时，可以进一步减小第一从节点发送的测量帧与测量节点发送的边缘测量帧的最大帧间隔，从而有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。Optionally, the arrangement order of the above-mentioned adjacent 1+M resource blocks corresponds to the time sequence in which the first slave node and the M measurement nodes send measurement frames on the 1+M resource blocks. It can also be configured through the master node. The node sends the second bitmap and/or scheduling information to determine the resource blocks of the first slave node and each measurement node, that is, determine the time sequence for sending measurement frames. When one of the adjacent 1+M resource blocks used for the first slave node to send the measurement frame is located in the middle of the 1+M resource blocks, the distance between the measurement frame sent by the first slave node and The maximum frame interval of edge measurement frames sent by the measurement node is beneficial to reducing the impact of the residual carrier frequency deviation CFO on the bidirectional measurement between the first slave node and the measurement node, and improving measurement accuracy.

如图5C所示，上述L＝2，M＝2，通信域包括第一从节点(T1节点)和对第一从节点执行测量的2×2个测量节点(G节点、T2节点、T3节点、T4节点)，相应的，信道资源包括(2+1)×2个资源块。As shown in Figure 5C, the above-mentioned L=2, M=2, the communication domain includes the first slave node (T1 node) and 2×2 measurement nodes (G node, T2 node, T3 node) that perform measurements on the first slave node. , T4 node), correspondingly, the channel resources include (2+1)×2 resource blocks.

其中，(2+1)×2个资源块中的2个资源块(如图5C中的第2、5个资源块)分别用于第一从节点发送测量帧，(2+1)×2个资源块中其余的2×2个资源块(如图5C中的第1、3、4、6个资源块)分别用于2×2个测量节点发送测量帧，并且在(2+1)×2个资源块中，2个资源块中的任一个资源块(如图5C中的第2个资源块或第5个资源块)与2×2个资源块中的2个资源块(如图5C中的第1、3个资源块，或第4、6个资源块)组成相邻的1+2个资源块。Among them, 2 of the (2+1)×2 resource blocks (the 2nd and 5th resource blocks in Figure 5C) are respectively used for the first slave node to send the measurement frame, (2+1)×2 The remaining 2×2 resource blocks in the resource blocks (the 1st, 3rd, 4th, and 6th resource blocks in Figure 5C) are respectively used for 2×2 measurement nodes to send measurement frames, and in (2+1) × 2 resource blocks, any one of the 2 resource blocks (the 2nd resource block or the 5th resource block in Figure 5C) is the same as 2 of the 2 × 2 resource blocks (such as The 1st and 3rd resource blocks in Figure 5C, or the 4th and 6th resource blocks) form adjacent 1+2 resource blocks.

结合图5C进行说明如下：The description is as follows in conjunction with Figure 5C:

Correspondingly, after the G node and T2 node receive the measurement frame sent by the first slave node, (2+1 )×2 resource blocks, the first resource block is used for the measurement node (G node) to send the measurement frame, and the third resource block is used for the measurement node (T2 node) to send the measurement frame, and, the 1st, 2nd, Three resource blocks form three adjacent resource blocks. The T1 node interacts with the G node and the T2 node respectively in measurement frames to realize the measurement frame interaction 1 in Figure 5C. In the same way, the fifth resource block among the (2+1)×2 resource blocks is used for the first slave node to send the measurement frame. Correspondingly, after the T3 node and T4 node receive the measurement frame sent by the first slave node, ( The 4th resource block among the 2+1)×2 resource blocks is used for the measurement node (T3 node) to send the measurement frame, and the 6th resource block is used for the measurement node (T4 node) to send the measurement frame, and the 4th resource block is used for the measurement node (T4 node) to send the measurement frame. , 5, and 6 resource blocks form three adjacent resource blocks, and the T1 node interacts with the T3 node and the T4 node respectively to implement measurement frame interaction 2 in Figure 5C.

可以理解为，在通信域的一次组播测量帧交互中，第一从节点在L个资源块中的任一个资源块上每发送一个测量帧，M×L个测量节点中的M个测量节点接收该测量帧后，会相应的在M×L个资源块中的M个资源块上各发送一个测量帧(即M×L个测量节点中的M个测量节点在M×L个资源块中的M个资源块上共发送M个测量帧)。It can be understood that in a multicast measurement frame interaction in the communication domain, every time the first slave node sends a measurement frame on any one of the L resource blocks, M measurement nodes among the M×L measurement nodes After receiving the measurement frame, a measurement frame will be sent correspondingly on M resource blocks among the M×L resource blocks (that is, M measurement nodes among the M×L measurement nodes are in the M×L resource blocks). A total of M measurement frames are sent on M resource blocks).

此时，在通信域的一次单播测量帧交互中，第一从节点和测量节点发送测量帧的数量比例为2:4。与上述图5A所示的组播测量帧相比，图5B中基于组播的测量帧交互可以通过适当提高第一从节点发送的测量帧数量，在保障测量帧传输效率以及第一从节点节省功耗和节省发送资源的同时，减小第一从节点发送的测量帧与测量节点发送的测量帧的帧间隔，有利于减小残留载波频率偏差CFO对第一从节点和测量节点之间双向测量的影响，提高测量精度。At this time, in a unicast measurement frame interaction in the communication domain, the ratio of the number of measurement frames sent by the first slave node and the measurement node is 2:4. Compared with the multicast measurement frame shown in Figure 5A above, the multicast-based measurement frame interaction in Figure 5B can appropriately increase the number of measurement frames sent by the first slave node to ensure measurement frame transmission efficiency and save money on the first slave node. While power consumption and transmission resources are saved, the frame interval between the measurement frame sent by the first slave node and the measurement frame sent by the measuring node is reduced, which is beneficial to reducing the residual carrier frequency deviation CFO for the two-way connection between the first slave node and the measuring node. Measurement effects and improve measurement accuracy.

在上述方式中，L表示将全部测量节点分成子组后的子组个数，例如，一共有5个测量节点和1个被测节点，如果L＝2，则表示将5个测量节点分成2个子组，每个子组具有

个测量节点，其中X表示测距组内测量节点的个数，

表示向上取整。上述运算中，将5个测量节点分成了2个子组，第一个子组有3个测量节点，第二个子组有2个测量节点，此时可以使用第二信息中的一个4比特位图，例如“0100”表示第一个子组的资源为“测量节点1、被测节点、测量节点2、测量节点3”，第二个子组的资源为“测量节点4，被测节点，测量节点5”，从而完成为全部测量节点和被测节点的资源配置。G节点可以将“L”的值和第二信息中包含的每个子组的资源位图，发送给各个测距成员节点，从而完成测距成员节点的资源配置。 In the above method, L represents the number of subgroups after dividing all measurement nodes into subgroups. For example, there are a total of 5 measurement nodes and 1 measured node. If L=2, it means that the 5 measurement nodes are divided into 2 subgroups, each with

measurement nodes, where X represents the number of measurement nodes in the ranging group,

Indicates rounding up. In the above operation, the 5 measurement nodes are divided into 2 subgroups. The first subgroup has 3 measurement nodes, and the second subgroup has 2 measurement nodes. At this time, a 4-bit bitmap in the second information can be used. , for example, "0100" means that the resources of the first subgroup are "measurement node 1, measured node, measurement node 2, measurement node 3", and the resources of the second subgroup are "measurement node 4, measured node, measurement node 5" to complete the resource configuration for all measuring nodes and measured nodes. The G node may send the value of “L” and the resource bitmap of each subgroup contained in the second information to each ranging member node, thereby completing the resource configuration of the ranging member node.

或者，所述第二信息还包括被测节点的发送测距帧的频率信息F，即被测节点每隔F个测量节点的测距帧资源，即***一个被测节点的测距帧资源。G节点将频率信息F发送给各个测距成员，从而完成测量节点和被测节点的测距帧资源配置。Alternatively, the second information also includes the frequency information F of the measured node for sending ranging frames, that is, the ranging frame resources of every F measuring nodes of the measured node, that is, the ranging frame resources of one measured node are inserted. The G node sends the frequency information F to each ranging member, thereby completing the ranging frame resource configuration of the measuring node and the measured node.

示例性的，上述第二信息指示的信道资源，还可参阅图5D，图5D为本申请实施例提供的一种信道资源示意图。Exemplarily, for the channel resources indicated by the above-mentioned second information, please refer to Figure 5D. Figure 5D is a schematic diagram of channel resources provided by an embodiment of the present application.

如图5D所示，通信域包括第一从节点(T1节点)和对第一从节点执行测量的2×2个测量节点(G节点、T2节点、T3节点、T4节点)，相应的，信道资源包括6个资源块。As shown in Figure 5D, the communication domain includes a first slave node (T1 node) and 2×2 measurement nodes (G node, T2 node, T3 node, T4 node) that perform measurements on the first slave node. Correspondingly, the channel Resources include 6 resource blocks.

在图5D中，T1节点与G节点之间的测量帧交互可以称为测量帧交互1，该测量帧交互1所对应的第一从节点(T1节点)和测量节点(G节点)发送测量帧的数量比例为1:1，T1节点与G节点发送测量帧各占用一个资源块，且T1节点发送测量帧占用的资源块与G节点发送测量帧占用的资源块组成相邻的(1+1)个资源块。并且，T1节点分别与T2节点、T3节点、T4节点之间的测量帧交互可以称为测量帧交互2，该测量帧交互2所对应的第一从节点(T1节点)和测量节点(T2节点、T3节点、T4节点)发送测量帧的数量比例为1:3，第一从节点(T1节点)和测量节点(T2节点、T3节点、T4节点)发送测量帧分别各占用一个资源块，且第一从节点(T1节点)和测量节点(T2节点、T3节点、T4节点)发送测量帧占用的资源块组成相邻的(1+3)个资源块。In Figure 5D, the measurement frame interaction between the T1 node and the G node can be called measurement frame interaction 1. The first slave node (T1 node) and the measurement node (G node) corresponding to the measurement frame interaction 1 send measurement frames. The ratio of the number is 1:1. The T1 node and the G node each occupy one resource block for sending the measurement frame, and the resource block occupied by the T1 node for sending the measurement frame and the resource block occupied by the G node for sending the measurement frame form an adjacent (1+1 ) resource blocks. Moreover, the measurement frame interaction between the T1 node and the T2 node, T3 node, and T4 node respectively can be called measurement frame interaction 2. The measurement frame interaction 2 corresponds to the first slave node (T1 node) and the measurement node (T2 node). , T3 node, T4 node), the ratio of the number of measurement frames sent is 1:3. The measurement frames sent by the first slave node (T1 node) and the measurement node (T2 node, T3 node, T4 node) each occupy one resource block, and The resource blocks occupied by the measurement frames sent by the first slave node (T1 node) and the measurement nodes (T2 node, T3 node, T4 node) form adjacent (1+3) resource blocks.

可以看出，本实施例中的信道资源配置方式与上述图5C所示的信道资源配置方式不同，通过配置信道资源的位置排布，可以使第一从节点和测量节点发送测量帧的数量比例多样化，根据不同的测量帧交互，分别配置不同位置排布的信道资源，使各个测量帧交互所对应的第一从节点和测量节点发送测量帧的数量比例不同。采用这种方式，既可以基于单播的测量交互取得较高的测量准确度，又可以基于组播的测量交互取得较高的测量效率。It can be seen that the channel resource configuration method in this embodiment is different from the channel resource configuration method shown in Figure 5C above. By configuring the position arrangement of the channel resources, the number of measurement frames sent by the first slave node and the measurement node can be proportional Diversification: According to different measurement frame interactions, channel resources arranged at different positions are respectively configured, so that the proportion of the number of measurement frames sent by the first slave node and the measurement node corresponding to each measurement frame interaction is different. In this way, both unicast-based measurement interaction can achieve higher measurement accuracy, and multicast-based measurement interaction can also achieve higher measurement efficiency.

可选的，对于多个被测节点时，如果采用单播测量(也称为成对测量)方式，则测量节点按照组播测量建立消息(如图4)中指示的顺序，与被测节点一对一对地测量交互；多个被测节点，则重复每个被测节点的单播测距帧结构，被测节点的发送顺序(发送资源块)也按照组播测量建立消息中的指示，依次与多个测量节点进行单播的测量交互。如图5E所示，为2个被测节点(T1和T4)与3个测量节点(G节点、T2节点、T3节点)进行测量交互的示意图，首先进行T1节点与G节点、T2节点、T3节点的单播式测量交互，之后再进行T4节点与G节点、T2节点、T3节点的单播式测量交互。采用这种方式，既可以基于单播的测量交互取得较高的测量准确度，又可以支持多个被测量设备与多个测量设备之间进行测量交互，取得类似于组播测量交互的高效率。Optionally, for multiple measured nodes, if unicast measurement (also called paired measurement) is used, the measuring node communicates with the measured node in the order indicated in the multicast measurement establishment message (as shown in Figure 4). Interaction is measured one-to-one; for multiple measured nodes, the unicast ranging frame structure of each measured node is repeated, and the sending sequence (sending resource blocks) of the measured nodes is also in accordance with the instructions in the multicast measurement establishment message. , perform unicast measurement interactions with multiple measurement nodes in sequence. As shown in Figure 5E, it is a schematic diagram of measurement interaction between two measured nodes (T1 and T4) and three measuring nodes (G node, T2 node, T3 node). First, the T1 node and G node, T2 node, T3 The unicast measurement interaction of the node is followed by the unicast measurement interaction between the T4 node and the G node, T2 node, and T3 node. In this way, high measurement accuracy can be achieved based on unicast measurement interaction, and measurement interaction between multiple measured devices and multiple measurement devices can be supported, achieving high efficiency similar to multicast measurement interaction. .

在一种可能的实施例中，主节点还向第一从节点和第二从节点发送第三信息。In a possible embodiment, the master node also sends third information to the first slave node and the second slave node.

其中，该第三信息用于指示测量帧的发送为单播发送(如上述图5B所示的单播发送)，或指示测量帧的发送为组播发送(如上述图5A和图5C所示的组播发送)。The third information is used to indicate that the transmission of the measurement frame is unicast transmission (as shown in the above-mentioned unicast transmission in Figure 5B), or to indicate that the transmission of the measurement frame is multicast transmission (as shown in the above-mentioned Figure 5A and Figure 5C). multicast transmission).

Correspondingly, the second slave node can also obtain measurement results by receiving the first measurement frame sent by the first slave node and sending the second measurement frame to the first slave node. The measurement results include but are not limited to the relative position of the first slave node. Position information such as distance and angle from the second slave node.

可选的，第一从节点还可以基于第一信息和第二信息，与第一从节点的多个测量节点进行测量帧交互，并得到多个测量结果。其中，该多个测量节点包括但不限于上述第二从节点，该多个测量结果包括但不限于第一从节点基于第二从节点发送的第二测量帧得到的测量结果。相应的，多个测量节点基于第一信息和第二信息，分别与第一从节点进行测量帧交互，也可以分别得到各自的测量结果。Optionally, the first slave node can also perform measurement frame interaction with multiple measurement nodes of the first slave node based on the first information and the second information, and obtain multiple measurement results. The plurality of measurement nodes include, but are not limited to, the above-mentioned second slave node, and the plurality of measurement results include, but are not limited to, measurement results obtained by the first slave node based on the second measurement frame sent by the second slave node. Correspondingly, multiple measurement nodes perform measurement frame interaction with the first slave node based on the first information and the second information, and can also obtain respective measurement results.

可选的，上述多个测量节点还可以包括主节点。此时，第一从节点还可以基于第一信息和第二信息与主节点进行测量帧交互，得到测量结果。Optionally, the above-mentioned plurality of measurement nodes may also include a master node. At this time, the first slave node can also perform measurement frame interaction with the master node based on the first information and the second information to obtain the measurement result.

例如，主节点在第三信道资源上发送第三测量帧，相应的，第一从节点在第三信道资源上接收主节点发送的第三测量帧；和，第一从节点在第四信道资源上发送第四测量帧，相应的，主节点在第四信道资源上接收第一从节点发送的第四测量帧。或者，第一从节点还可以是在上述第一信道资源上发送第一测量帧，相应的，主节点在第一信道资源上接收第一从节点发送的第一测量帧。For example, the master node sends the third measurement frame on the third channel resource, and accordingly, the first slave node receives the third measurement frame sent by the master node on the third channel resource; and, the first slave node receives the third measurement frame on the fourth channel resource. The fourth measurement frame is sent on the first slave node. Correspondingly, the master node receives the fourth measurement frame sent by the first slave node on the fourth channel resource. Alternatively, the first slave node may also send the first measurement frame on the first channel resource, and accordingly, the master node receives the first measurement frame sent by the first slave node on the first channel resource.

在一种可能的实施例中，多个测量节点(包括但不限于第二从节点)在基于与第一从节点进行测量帧交互得到多个测量结果后，还将各自得到的测量结果发送给主节点。In a possible embodiment, after multiple measurement nodes (including but not limited to the second slave node) obtain multiple measurement results based on measurement frame interaction with the first slave node, they also send their respective measurement results to master node.

在一种可能的实施例中，第一从节点和各个测量节点之间的测量帧交互是在不同的信道上进行，即第一从节点和各个测量节点跳频发送测量帧。通过跳频发送测量帧，可以扩大跳频测距的测量带宽，以提高测距的准确性和精度。In a possible embodiment, the measurement frame interaction between the first slave node and each measurement node is performed on different channels, that is, the first slave node and each measurement node send measurement frames through frequency hopping. By sending measurement frames through frequency hopping, the measurement bandwidth of frequency hopping ranging can be expanded to improve the accuracy and precision of ranging.

对于SLB，由于不支持T节点和T节点之间的直接通信，因此，可采用每个T节点将测量的CSI信息反馈至G节点，再由G节点再发送至测距测角定位功能解算节点(简称解算节点)进行距离/角度/位置解算方式。For SLB, since direct communication between T nodes and T nodes is not supported, each T node can be used to feed back the measured CSI information to the G node, and then the G node sends it to the ranging and angle positioning function for solution. Nodes (referred to as solution nodes) perform distance/angle/position calculation methods.

具体可参阅图6A和图6B，图6A和图6B为本申请实施例提供的两种信道状态信息CSI的交互示意图。For details, please refer to FIG. 6A and FIG. 6B. FIG. 6A and FIG. 6B are schematic diagrams of the interaction of two types of channel state information CSI provided by embodiments of the present application.

如图6A所示，解算节点是第三方节点。G节点分别接收T1、T2和T3的CSI反馈，并且反馈测量结果(CSI)的帧结构包括如下信息：源节点的测量标识；目的节点的测量标识；测量transaction ID；CSI信息。CSI信息可以如下表示。As shown in Figure 6A, the solution node is a third-party node. The G node receives the CSI feedback of T1, T2 and T3 respectively, and the frame structure of the feedback measurement result (CSI) includes the following information: the measurement ID of the source node; the measurement ID of the destination node; the measurement transaction ID; CSI information. CSI information can be represented as follows.

T1节点反馈CSI：G-T1，T2-T1，T3-T1；T1 node feedback CSI: G-T1, T2-T1, T3-T1;

T2节点反馈CSI：T1-T2；T2 node feedback CSI: T1-T2;

T3节点反馈CSI：T1-T3；T3 node feedback CSI: T1-T3;

其中，G-T1表示“G发送测距帧，T1接收测距帧”获得的CSI。Among them, G-T1 represents the CSI obtained by "G sends the ranging frame and T1 receives the ranging frame".

G节点向测距、测角解算功能节点发送T2-T1，T3-T1，T1-T2，T1-T3之后，分别合并以下CSI：T2-T1与T1-T2；T3-T1与T1-T3；G-T1与T1-G。测距、测角解算功能节点根据合并后的CSI计算得到测距结果。After the G node sends T2-T1, T3-T1, T1-T2, and T1-T3 to the ranging and angle measurement function nodes, the following CSIs are merged respectively: T2-T1 and T1-T2; T3-T1 and T1-T3 ;G-T1 and T1-G. The ranging and angle measurement function nodes calculate the ranging results based on the combined CSI.

上述方案中，解算节点还可以与G节点是同一个节点，或者是T节点。T节点测量的对侧T节点的CSI，全部反馈至G节点，再由G节点发送至测距/测角解算功能节点。In the above solution, the solution node can also be the same node as the G node, or it can be the T node. The CSI of the contralateral T node measured by the T node is all fed back to the G node, and then sent by the G node to the ranging/angle measurement function node.

对于解算功能节点是对侧T节点的情况，如图6B所示。G节点接收到各个T节点上报的CSI之后，再分别按目的节点的测量标识，发送(转发)至各个解算功能节点。例如，G节点收到T1反馈的T2-T1、T3-T1、G-T1之后，再分别将T2-T1、T3-T1发送至T2、T3。G节点对收到的CSI，仅按照目的地址、transaction ID等进行发送，内容上不做修改。各个解算功能节点根据收到的CSI，以及测量的CSI，计算得到距离。For the case where the solution function node is the contralateral T node, as shown in Figure 6B. After the G node receives the CSI reported by each T node, it sends (forwards) it to each solution function node according to the measurement identification of the destination node. For example, after G node receives T2-T1, T3-T1, and G-T1 fed back by T1, it sends T2-T1 and T3-T1 to T2 and T3 respectively. The G node only sends the received CSI according to the destination address, transaction ID, etc., without modifying the content. Each calculation function node calculates the distance based on the received CSI and the measured CSI.

对于功能解算节点的选取，可以在测距参数协商时，T节点可以向G节点报告自己的测距/测角解算功能节点能力，或者G节点根据高层信令获取。再例如，对于图2，假设节点a是主节点，节点A是第一从节点(被测量节点)，节点b是第二从节点(测量节点/定位锚点)，由于本申请采用双向测量的方式，因此第一从节点、第二从节点测量得到的测量结果信息(例如信道状态信息)，发送给主节点，由主节点(测距/测角解算节点)根据收集/测量的结果信息进行合并和计算。这样做的优势在于，第一从节点和第二从节点之间无需交互测量结果，而是把自己的测量结果上报给主节点，由主节点根据收集的测量信息进行距离计算，避免了在第一从节点与第二从节点之间交互信息所需的复杂链路。For the selection of functional solution nodes, the T node can report its own ranging/angle measurement function node capabilities to the G node during the ranging parameter negotiation, or the G node can obtain it based on high-level signaling. For another example, for Figure 2, assume that node a is the master node, node A is the first slave node (measured node), and node b is the second slave node (measuring node/positioning anchor point). Since this application uses bidirectional measurement method, so the measurement result information (such as channel state information) measured by the first slave node and the second slave node is sent to the master node, and the master node (ranging/angle measurement solution node) collects/measures the result information based on the Consolidate and calculate. The advantage of this is that there is no need to exchange measurement results between the first slave node and the second slave node. Instead, they report their own measurement results to the master node, and the master node performs distance calculations based on the collected measurement information, avoiding the need for A complex link required to exchange information between one slave node and a second slave node.
