具体实施方式Detailed ways
在中继节点接入网络的过程中，包含两种方式：一种是终端自行选择路径；一种是DgNB选择路径。本申请实施例提供的方案致力于后者，更具体的，是涉及IAB(integrated access backhaul，集成/综合接入回程线路)选择接入路径，并上报DgNB进行管理的方案。下面结合附图对本发明的具体实施方式进行说明。In the process of the relay node accessing the network, there are two methods: one is that the terminal selects the path by itself; the other is that the DgNB selects the path. The solution provided in the embodiment of the present application is devoted to the latter, and more specifically, a solution involving IAB (integrated access backhaul) to select an access path and report it to DgNB for management. The following describes specific embodiments of the present invention with reference to the accompanying drawings.
在说明过程中，将分别从接入的RN侧与基站侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本发明实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当接入的RN侧与基站分开实施时，其也各自解决接入的RN侧、基站侧的问题，而二者结合使用时，会获得更好的技术效果。In the description process, the implementation from the access RN side and the base station side will be described separately, and then an example of the implementation of both will be given to better understand the implementation of the solution given in the embodiment of the present invention. This way of description does not mean that the two must be implemented in cooperation or separately. In fact, when the RN side of the access is implemented separately from the base station, it also solves the problems of the RN side and the base station side of the access separately. When the two are used in combination, better technical results will be obtained.
在5G***中，中继节点接入DgNB(Donor gNB，施主基站)的路径选择，以及当路径中断的Donor gNB重新配置的过程。中继节点被称为IAB(integrated access backhaul，集成/综合接入回程线路)node(节点)，本发明实施例中也采用该命名。In a 5G system, the path selection for a relay node to access DgNB (Donor NB, donor base station), and the process of reconfiguration of Donor NB when the path is interrupted. The relay node is called an IAB (integrated access backhaul) node, and this name is also used in the embodiment of the present invention.

图4为网络结构示意图，如图所示，该网络结构为可以实施本发明实施例中提供的方案的网络架构之一，为更好地理解本发明实施例中提供的方案的实施，现结合该结构进行说明。FIG. 4 is a schematic diagram of a network structure. As shown in the figure, the network structure is one of the network architectures that can implement the solutions provided in the embodiments of the present invention. In order to better understand the implementation of the solutions provided in the embodiments of the present invention, we will now combine This structure will be described.
本实例中，RN8为第一RN，RN2为第二RN，RN7为第三RN。容易理解，RN8、RN2、RN7是具体的实例，同时还需要指出，本例中是以一个第二RN、一个第三RN为例进行说明的，实际上，在方案中是可以存在多个第二RN、第三RN的，也即，此种情况下存在多条激活中继链路路径、以及多条备用中继链路路径，但在获知一条激活中继链路路径、备用中继链路路径实施的情况下，也容易获知多条路径下的实施。In this example, RN8 is the first RN, RN2 is the second RN, and RN7 is the third RN. It is easy to understand that RN8, RN2, and RN7 are specific examples. It should also be pointed out that in this example, a second RN and a third RN are used as an example. In fact, there may be multiple first RNs in the solution. For the second RN and third RN, that is, in this case, there are multiple active relay link paths and multiple standby relay link paths, but after learning that one active relay link path and standby relay link In the case of implementation of road paths, it is easy to know the implementation of multiple paths.
如图4所示，在RN8加入网络的过程中，选择的路径可以为RN8->RN2->Donor gNB，或者RN8->RN7->Donor gNB。在L2IAB架构中，RN2和RN7可以通过F1信令上报负载状况，包括无线负载，硬件负载，传输负载。在L3的LAB架构中，RN2和RN7可以通过Ng接口传递负载情况。同时，DgNB了解RN7和RN2的信道质量，因此DgNB可以依据RN7和RN2的信道质量，以及RN7和RN2的负载对RN8进行配置。As shown in FIG. 4, in the process of RN8 joining the network, the selected path can be RN8-> RN2-> Donor NB, or RN8-> RN7-> Donor NB. In the L2IAB architecture, RN2 and RN7 can report the load status through F1 signaling, including wireless load, hardware load, and transmission load. In the LAB architecture of L3, RN2 and RN7 can transfer the load situation through the Ng interface. At the same time, DgNB knows the channel quality of RN7 and RN2, so DgNB can configure RN8 according to the channel quality of RN7 and RN2 and the load of RN7 and RN2.
也即，实施中，在DgNB侧，第二RN和/或第三RN的负载在L2IAB架构中，是通过F1信令上报的；和/或，That is, in the implementation, on the DgNB side, the load of the second RN and / or the third RN is reported in the L2IAB architecture through F1 signaling; and / or,
第二RN和/或第三RN的负载在L3的LAB架构中，是通过Ng接口传递的。The load of the second RN and / or the third RN is transmitted through the Ng interface in the L3 LAB architecture.
也由此可以看出，在步骤102实施中，确定DgNB与第二RN之间的信道质量，以及DgNB与第三RN之间的信道质量；It can also be seen from this that in the implementation of step 102, the channel quality between DgNB and the second RN and the channel quality between DgNB and the third RN are determined;
以及，在接收到第一RN的测量报告后，根据测量报告确定第一RN与第二RN之间的信道质量，以及第一RN与第三RN之间的信道质量；And after receiving the measurement report of the first RN, determining the channel quality between the first RN and the second RN and the channel quality between the first RN and the third RN according to the measurement report;
这四个信道质量之间并无直接关系，因而在确定它们时并无时序关系，实施中可以根据需要来进行确定。There is no direct relationship between the four channel qualities, so there is no timing relationship when determining them, and it can be determined according to needs during implementation.
由于IAB网络主要用来扩展网络覆盖，因此假定的IAB node工作场景是一条激活链路，一条备用链路。当激活链路中断时候，IAB node自动切换到 备用链路。下面将对包括链路建立和链路切换等过程进行说明。Because the IAB network is mainly used to extend network coverage, the assumed IAB node working scenario is an active link and a standby link. When the active link is interrupted, the IAB node automatically switches to the standby link. The processes including link establishment and link switching will be described below.
实施例1：Example 1:
本例中，将进行链路建立过程的实施说明。In this example, the implementation of the link establishment process will be explained.
图5为路径配置过程实施流程示意图，如图所示，可以包括：Figure 5 is a schematic diagram of the implementation process of the path configuration process. As shown in the figure, it may include:
步骤501、DgNB经RN7向RN8发送路径配置命令；Step 501: DgNB sends a path configuration command to RN8 via RN7.
步骤502、RN8经RN7向DgNB返回路径配置响应。Step 502: RN8 returns a path configuration response to DgNB via RN7.
具体的流程可以如下：The specific process can be as follows:
1：RN8开机后作为UE(User Equipment，用户终端)接入网络，在接入网络过程中，根据小区选择criteria(标准)，选择RN7接入网络。1: RN8 accesses the network as UE (User Equipment) after powering on. During the process of accessing the network, RN7 is selected to access the network according to the cell selection criteria (standard).
2：由于RN7并没有RRC(Radio Resource Control，无线资源控制)功能，因此DgNB通过RRC为RN8配置测量，RN8对RN7、RN2进行测量上报，也即：实施中，在DgNB侧，DgNB可以是通过RRC功能为第一RN配置对第二RN以及第三RN的测量。2: RN7 does not have RRC (Radio Resource Control) function, so DgNB configures measurement for RN8 through RRC, and RN8 measures and reports RN7 and RN2, that is, during implementation, on the DgNB side, DgNB can pass The RRC function configures the measurement of the second RN and the third RN for the first RN.
3：DgNB根据RN8上报的RN8->RN7和RN8->RN2的信道质量，以及RN7和RN2的负载，以及RN7和RN2到DgNB的信道质量，假设计算出RN8->RN2->DgNB是最佳路径，也即，RN8->RN2->DgNB将作为激活中继链路路径，而RN8->RN7->DgNB将作为备用中继链路路径。3: DgNB According to the channel quality reported by RN8-> RN7 and RN8-> RN2, and the load of RN7 and RN2, and the channel quality of RN7 and RN2 to DgNB, it is assumed that RN8-> RN2-> DgNB is the best The path, that is, RN8-> RN2-> DgNB will be used as the active relay link path, and RN8-> RN7-> DgNB will be used as the standby relay link path.
4：DgNB通过RN7发送RRC消息配置RN8的接入路径为RN8->RN2->DgNB。4: DgNB sends an RRC message through RN7 to configure the access path of RN8 to RN8-> RN2-> DgNB.
5：RN8通过一个通信模块保持与RN7的连接，同时RN8通过独立于用于连接RN7的另一个通信模块连接到RN2，并且配置RN2为主链接链路，RN7为备用链接链路。也即：实施中，在接入的RN侧，可以使用第一通信模块在激活中继链路路径上进行数据传输，当需要在备用中继链路路径上进行数据传输时使用第二通信模块进行数据传输。5: RN8 maintains the connection with RN7 through one communication module, and at the same time, RN8 connects to RN2 through another communication module that is used to connect to RN7, and configures RN2 as the primary link link and RN7 as the backup link link. That is, in the implementation, on the accessing RN side, the first communication module can be used for data transmission on the active relay link path, and the second communication module is used when data transmission is required on the standby relay link path. Data transfer.
实施例2：Example 2:
本例中，将对链路恢复过程的实施进行说明。In this example, the implementation of the link recovery process will be described.
如实施例1所描述，当前RN8->RN2->DgNB为激活链路， RN8->RN7->DgNB为备用链路。As described in Embodiment 1, the current RN8-> RN2-> DgNB is the active link, and RN8-> RN7-> DgNB is the standby link.
方式1：Way 1:
设RN8->RN2链路中断，RN8发起备用中继链路路径激活，激活中继链路路径删除流程。Suppose RN8-> RN2 link is interrupted, RN8 initiates the backup relay link path activation, and activates the relay link path deletion process.
也即，实施中，当激活中继链路路径中断时，可以进一步包括：That is, in the implementation, when the path of the activated relay link is interrupted, it may further include:
激活备用中继链路路径；和/或，Activate the alternate trunk link path; and / or,
删除激活中继链路路径。Remove the active trunk link path.
图6为激活中继链路路径中断情况下方式1的实施流程示意图，如图所示，可以包括：FIG. 6 is a schematic diagram of an implementation process of Mode 1 in the case of a path interruption of an activated relay link, as shown in the figure, which may include:
步骤601、RN8经RN7向DgNB发送激活备用路径请求；Step 601: RN8 sends a request for activating a standby path to DgNB via RN7;
步骤602、DgNB经RN7向RN8返回激活备用路径确认。Step 602: The DgNB returns an activation standby path confirmation to RN8 via RN7.
实施中，激活中继链路路径中断可以是在按DgNB的配置进行的测量中进行检测确定的。具体的，DgNB给RN8配置了测量，当RN8使用配置的测量配置测量到RN2的信号强度发生高频闪断，即中断向RN2发送数据，并直接切换到RN7。同时发送切换请求，激活备用中继链路路径。这种情况为IAB node自行发起激活备用链路请求，激活备用链路请求中包含删除已经断开的激活链路的请求。这样可以更新DgNB中对IAB node链路的维护。In the implementation, the path interruption of the activated relay link may be detected and determined in a measurement performed according to the configuration of the DgNB. Specifically, DgNB configures measurement for RN8. When RN8 uses the configured measurement configuration to measure the signal strength of RN2, a high-frequency flicker occurs, that is, the sending of data to RN2 is interrupted, and it is directly switched to RN7. At the same time, a switch request is sent to activate the backup relay link path. In this case, the IAB node initiates a request to activate the standby link by itself, and the request for activating the standby link includes a request to delete the active link that has been disconnected. This can update the maintenance of the IAB node link in DgNB.
当RN7变成激活中继链路路径后，由于RN8与RN2连接的另一通信模块空闲，因此这一通信模块启动小区选择过程，选择RN9作为备用中继链路路径。随后调用实施例1中的链路建立过程，建立RN9作为备用中继链路路径。也即，实施中，在接入的RN侧，在删除激活中继链路路径后，还可以进一步包括：When RN7 becomes the active relay link path, because another communication module connected to RN8 and RN2 is idle, this communication module starts the cell selection process and selects RN9 as the backup relay link path. Subsequently, the link establishment process in Embodiment 1 is called, and RN9 is established as a backup relay link path. That is, in the implementation, on the access RN side, after the active relay link path is deleted, it may further include:
使用第一通信模块启动小区选择过程，并将选择到的中继链路路径作为备用中继链路路径。The first communication module is used to start the cell selection process, and the selected relay link path is used as a backup relay link path.
方式2：Way 2:
假设RN2->DgNB链路中断。Assume that RN2-> DgNB link is down.
则实施中，当激活中继链路路径中断时，可以进一步包括：In the implementation, when the path of the active relay link is interrupted, the method may further include:
通过备用中继链路路径指示第一RN激活备用中继链路路径；和/或，Instruct the first RN to activate the backup relay link path through the backup relay link path; and / or,
根据第一RN的请求指示第一RN激活备用中继链路路径。The first RN is instructed to activate the backup relay link path according to the request of the first RN.
具体的，当RN2-DgNB链路中断后，由于RN8并不知道RN2和DgNB中继链路已经中断，并且当前中继节点RN2并没有RRC功能，因此RN8并不能从RN2获得重新建立链路的指示。那么有如下两种方案可以触发RN8切换链路：Specifically, when the RN2-DgNB link is interrupted, because RN8 does not know that the RN2 and DgNB relay links have been interrupted, and the current relay node RN2 does not have the RRC function, RN8 cannot obtain the re-established link from RN2. Instructions. Then there are two schemes that can trigger RN8 handover link:
方案1：DgNB发起备用中继链路路径激活和中继链路路径更新。Solution 1: DgNB initiates backup relay link path activation and relay link path update.
也即，在DgNB侧，通过备用中继链路路径指示第一RN激活备用中继链路路径。That is, on the DgNB side, the first RN is instructed to activate the backup relay link path through the backup relay link path.
图7为链路中断情况下方式2之方案1的实施流程示意图，如图所示，可以包括：FIG. 7 is a schematic diagram of the implementation process of Option 1 of Mode 2 in the case of a link interruption. As shown in the figure, it may include:
步骤701、DgNB经RN7向RN8发送激活备用路径命令；Step 701: DgNB sends a command to activate the standby path to RN8 via RN7;
步骤702、RN8经RN7向DgNB返回激活备用路径响应。Step 702: RN8 returns an active standby path response to DgNB via RN7.
具体的，由于在上面实施例1中，DgNB保存了RN8的备用链路路径，因此DgNB可以检测到RN2->DgNB的链路中断，那么DgNB可以通过备用路径DgNB->RN7->RN8来发送激活备用路径的命令。该方案适用于L2中继架构。Specifically, in the above embodiment 1, DgNB saves the backup link path of RN8, so DgNB can detect the link interruption of RN2-> DgNB, so DgNB can send it through the backup path DgNB-> RN7-> RN8. Command to activate alternate paths. This solution is applicable to the L2 relay architecture.
方案2：RN8发起备用中继链路路径激活和中继链路路径更新。Solution 2: RN8 initiates backup relay link path activation and relay link path update.
也即，在DgNB侧，根据第一RN的请求指示第一RN激活备用中继链路路径。That is, on the DgNB side, the first RN is instructed to activate the backup relay link path according to the request of the first RN.
在接入的RN侧，激活中继链路路径中断是由激活中继链路路径上的RN通知。当然，在接到该通知获知链路中断后，第一RN激活备用中继链路路径；和/或，删除激活中继链路路径。On the accessing RN side, the interruption of the active relay link path is notified by the RN on the active relay link path. Of course, after receiving the notification and learning that the link is interrupted, the first RN activates the backup relay link path; and / or deletes the activated relay link path.
图8为链路中断情况下方式2之方案2的实施流程示意图，如图所示，可以包括：FIG. 8 is a schematic diagram of an implementation process of Option 2 of Mode 2 in the case of a link interruption. As shown in the figure, it may include:
步骤801、RN2向RN8发送链路中断指示；Step 801: RN2 sends a link interruption indication to RN8.
步骤802、RN8经RN7向DgNB发送激活备用路径请求；Step 802: RN8 sends a request for activating a standby path to DgNB via RN7;
步骤803、DgNB经RN7向RN8返回激活备用路径确认。Step 803: The DgNB returns an activation standby path confirmation to RN8 via RN7.
图9为链路中断情况下方式2之方案2的L3中继实施流程示意图，如果是L3中继，那么消息流程如图所示，可以包括：FIG. 9 is a schematic diagram of the implementation process of the L3 relay of the second option 2 in the case of a link interruption. If the L3 relay is an L3 relay, the message flow is shown in the figure and may include:
步骤901、RN2向RN8发送链路中断指示；Step 901: RN2 sends a link interruption indication to RN8.
步骤902、RN8向RN7发送激活备用路径请求；Step 902: RN8 sends a request for activating a standby path to RN7.
步骤903、RN7向DgNB发送激活备用路径请求；Step 903: The RN7 sends a request to activate the standby path to the DgNB.
步骤904、DgNB向RN7返回激活备用路径确认；Step 904: DgNB returns an acknowledgement to the RN7 to activate the standby path;
步骤905、RN7向RN8返回激活备用路径确认。Step 905: RN7 returns an active standby path confirmation to RN8.
具体的，RN2在检测到与DgNB的链路中断后，由于和RN8的链路尚未中断，因此给RN8发送链路中断指示，RN8收到此指示后，自己启动备用路径激活流程。Specifically, after detecting a link interruption with DgNB, RN2 sends a link interruption indication to RN8 because the link with RN8 has not been interrupted. After receiving this indication, RN8 starts the standby path activation process by itself.
实施例3：Example 3:
在本实施例中，UE同时拥有多个激活中继链路路径，UE自由选择任何激活中继链路路径进行发送。也即存在多条激活中继链路路径、以及多条备用中继链路路径的情况下的实施。该情况下：In this embodiment, the UE has multiple active relay link paths at the same time, and the UE is free to select any active relay link path for transmission. That is, the implementation is performed when there are multiple activated relay link paths and multiple standby relay link paths. In this case:
在DgNB侧，在所述激活中继链路路径有至少两条时，进一步包括：On the DgNB side, when there are at least two active relay link paths, the method further includes:
在每条激活中继链路路径上传输的数据都相同时，丢弃多余的数据；和/或，When the data transmitted on each active relay link path is the same, discard the excess data; and / or,
在不同的激活中继链路路径上传输的数据不相同时，将不同的数据组合后还原。When the data transmitted on different active relay link paths is different, the different data are combined and restored.
在接入的RN侧，在所述激活中继链路路径有至少两条时，进一步包括：On the access RN side, when there are at least two active relay link paths, the method further includes:
在每条激活中继链路路径上传输相同的数据；和/或，Transmit the same data on each active relay link path; and / or,
将数据分成不同部分后，在不同的激活中继链路路径上传输。After the data is divided into different parts, it is transmitted on different active relay link paths.
具体的，RN可以在多条链路进行两种发送：Specifically, the RN can perform two types of transmission on multiple links:
1：在多条链路发送相同的duplication(复制)的数据包。1: Send the same duplicated packet over multiple links.
例如，在链路1上发送PDCP(Packet Data Convergence Protocol，分组数据聚合协议)PDU(Protocol Data Unit，协议数据单元)1、PDCP PDU 2、 PDCP PDU 3的数据包，在链路2上重复发送PDCP PDU 1、PDCP PDU 2、PDCP PDU 3，以增强可靠性传输。这样在一条链路上发送失败，在另一条链路上发送成功也可以实现可靠传输。For example, a data packet of PDCP (Packet Data Convergence Protocol) PDU (Protocol Data Unit) 1, PDCP PDU 2, PDCP PDU 3 is repeatedly sent on link 1 and repeatedly sent on link 2. PDCP, PDU1, PDCP, PDU2, PDCP, PDU3 to enhance reliable transmission. In this way, transmission fails on one link, and successful transmission on another link can also achieve reliable transmission.

2：在多条激活中继链路路径发送不同的数据包。2: Send different packets on multiple active relay link paths.
例如在激活中继链路路径1上发送PDCP PDU 1、PDCP PDU 2、PDCP PDU 3的数据包，在链路2上发送PDCP PDU 4、PDCP PDU 5、PDCP PDU 6的数据包，这样可以增加吞吐量。For example, send data packets of PDCP PDU1, PDCP PDU2, PDCP PDU3, and PDCP PDU4, PDCP PDU5, and PDCP PDU6 on link 2 of the active relay link path. This can increase Throughput.
在这种发送方式下，对端PDCP实体负责多条激活中继链路路径接收的重排序实体，根据PDCP SN序号进行重排序。比如从两条激活中继链路路径上接收的PDCP SN号顺序依次为PDCP PDU 1、PDCP PDU 4、PDCP PDU 2、PDCP PDU 5、PDCP PDU 6、PDCP PDU 3，那么要根据PDCP SN进行重新排序。In this sending mode, the opposite PDCP entity is responsible for multiple reordering entities that activate the relay link path to receive, and reorders according to the PDCP SN sequence number. For example, the PDCP and SN numbers received from the two active relay link paths are in order: PDCP, PDU1, PDCP, PDU4, PDCP, PDU2, PDCP, PDU5, PDCP, PDU6, PDCP, PDU3, and so on. Sort.
