IAB为用户提供无线接入的基站，需要回传链路连接核心网或者其他基站。一般回传链路采用有线回传，如光纤，与核心网或者其他基站连接，用于数据的回传。无线回传链路主要采用微波回传作为无光纤场景下的重要传输手段。目前全球有50％～60％的移动基站通过微波进行回传，随着5G部署步伐的加快，网络容量、复杂性、时延要求更高，移动基站的数量也会增加，无线回传的应用范围会继续扩大。The base station that IAB provides wireless access to users requires a backhaul link to connect to the core network or other base stations. Generally, the backhaul link uses wired backhaul, such as optical fiber, to connect to the core network or other base stations for data backhaul. The wireless backhaul link mainly uses microwave backhaul as an important transmission method in the absence of fiber. At present, 50% to 60% of mobile base stations in the world are backhauled through microwave. With the acceleration of 5G deployment, network capacity, complexity, and delay requirements are higher, and the number of mobile base stations will increase. The application of wireless backhaul The scope will continue to expand.

与LTE相比，5G NR技术能够使用更大的带宽，例如可以使用毫米波频段，并且可以应用大规模天线和多波束***，因此5G能够提供更高的***速率，为IAB的应用提供了条件。所谓IAB基站，就是该基站集成了无线接入链路(即接入链路(Access link))和无线回传链路(即回程链路(Backhaul link))，其中接入链路为UE与IAB基站之间的通信链路，无线回程链路为IAB基站之间的通信链路，进行数据回传，因此IAB基站不需要有线传输网络进行数据回传。基于此，IAB基站更容易部署在密集和复杂场景，减轻了部署有线传输网络的负担。Compared with LTE, 5G NR technology can use a larger bandwidth, for example, millimeter wave frequency bands can be used, and large-scale antennas and multi-beam systems can be applied. Therefore, 5G can provide a higher system rate and provide conditions for the application of IAB . The so-called IAB base station means that the base station integrates a wireless access link (Access link) and a wireless backhaul link (Backhaul link). The access link is the UE and The communication link between the IAB base stations, the wireless backhaul link is the communication link between the IAB base stations for data back transmission, so the IAB base station does not need a wired transmission network for data back transmission. Based on this, IAB base stations are easier to deploy in dense and complex scenarios, reducing the burden of deploying wired transmission networks.

如图1所示，IAB基站为UE提供无线接入和接入业务的无线回传。IAB donor基站(归属IAB基站)向IAB基站提供无线回传功能，并提供UE与核心网的接口。从图1中可以看出，IAB donor基站与核心网有有线连接，IAB基站与核心网之间没有有线连接，IAB基站通过无线回传链路连接到IAB donor基站，从而使UE与核心网进行连接。As shown in Figure 1, the IAB base station provides wireless access and wireless backhaul of access services for the UE. The IAB donor base station (home IAB base station) provides wireless backhaul function to the IAB base station and provides the interface between the UE and the core network. It can be seen from Figure 1 that the IAB donor base station has a wired connection with the core network, and there is no wired connection between the IAB base station and the core network. The IAB base station is connected to the IAB donor base station through a wireless backhaul link, so that the UE can communicate with the core network. connection.

另外，如果一个IAB基站控制和调度另外一个IAB基站，则该IAB基站可以称为父节点，即该IAB基站为另外一个IAB基站的父节点，如图2所示，IAB基站2可以称为父节点，它是IAB基站3的父节点。如果一个IAB基站在另外一个IAB基站的控制之下，则该IAB基站可以称为子节点，即该IAB基站为另外一个IAB基站的子节点。如图2所示，IAB基站1，IAB基站2，IAB基站3都可以称之为子节点，其中IAB基站1和IAB基站2是IAB donor基站的子节点，IAB基站3是IAB基站2的子节点。显然，同一个IAB基站可能既是父节点，又是子节点。并且，IAB donor基站只能是父节点，图2中IAB donor基站是IAB基站1和IAB基站2的父节点。对于IAB基站，考虑到半双工的限制，IAB基站不能在回程链路和接入链路同时接收和发送数据，即当IAB基站接收父节点的回程链路数据时，不能在接入链路发送数据，当IAB基站在回程链路向父节点发送数据时，不能在接入链路接收数据。如图2所示，当IAB基站1接收其父节点(IAB donor基站，在拓扑结构中可以视为IAB基站等同处理)的回程链路数据时，不能向UE1通过接入链路发送数据。当IAB基站2向其父节点(IAB donor基站)通过回程链路发送数据时，不能接收UE1通过接入链路发送的数据。In addition, if an IAB base station controls and schedules another IAB base station, the IAB base station can be called the parent node, that is, the IAB base station is the parent node of another IAB base station. As shown in Figure 2, the IAB base station 2 can be called the parent node. Node, which is the parent node of IAB base station 3. If an IAB base station is under the control of another IAB base station, the IAB base station can be called a child node, that is, the IAB base station is a child node of another IAB base station. As shown in Figure 2, IAB base station 1, IAB base station 2, and IAB base station 3 can all be called child nodes. Among them, IAB base station 1 and IAB base station 2 are the child nodes of IAB donor base station, and IAB base station 3 is the child node of IAB base station 2. node. Obviously, the same IAB base station may be both a parent node and a child node. In addition, the IAB donor base station can only be the parent node. In Figure 2, the IAB donor base station is the parent node of the IAB base station 1 and the IAB base station 2. For the IAB base station, considering the limitation of half-duplex, the IAB base station cannot receive and send data at the same time on the backhaul link and the access link. That is, when the IAB base station receives the backhaul link data of the parent node, it cannot Send data. When the IAB base station sends data to the parent node on the backhaul link, it cannot receive data on the access link. As shown in Figure 2, when the IAB base station 1 receives backhaul link data from its parent node (IAB donor base station, which can be treated as equivalent to the IAB base station in the topology), it cannot send data to UE1 through the access link. When the IAB base station 2 sends data to its parent node (IAB donor base station) through the backhaul link, it cannot receive the data sent by the UE1 through the access link.

对于IAB基站来说，可能不是直接与IAB donor基站直接建立backhaul link，而是通过多跳的方式与IAB donor基站建立backhaul link，例如图3中的子节点与IAB基站，IAB基站与父节点建立backhaul link。对于IAB基站来说，由于半双工的限制，不能在接收UE和子节点发送的RACH的同时和向其父节点发送RACH。因此，对于相邻的IAB基站，它们配置的RACH资源需要是时分的。一种方法是由父节点，如IAB donor为网络中所有的IAB基站配置RACH资源，这种方法具有比较大的实现复杂度。另一种方式是由IAB基站根据自己配置的RACH资源配置，通过一个offset来获得时分的RACH资源，用于该IAB基站向其父节点发送RACH的资源配置。For the IAB base station, it may not directly establish a backhaul link with the IAB donor base station, but establish a backhaul link with the IAB donor base station in a multi-hop manner, such as the child node and the IAB base station in Figure 3, and the IAB base station and the parent node. backhaul link. For the IAB base station, due to the limitation of half-duplex, the RACH cannot be sent to the parent node while receiving the RACH sent by the UE and the child node. Therefore, for adjacent IAB base stations, the RACH resources they configure need to be time-division. One method is that the parent node, such as the IAB donor, configures RACH resources for all IAB base stations in the network. This method has a relatively large implementation complexity. Another way is that the IAB base station obtains the time-division RACH resource through an offset according to the RACH resource configuration configured by the IAB base station, which is used for the IAB base station to send the RACH resource configuration to its parent node.

在Rel-15 NR技术中，定义了为接入UE配置的RACH资源，包括256种配置。小区使用的RACH资源配置信息在***消息中指示给接入的UE。对于FR2的非成对频谱的RACH资源配置如下表1所示。其中，每一种RACH资源配置包含了前导格式(preamble format)，RACH时机所在的无线帧的周期(x)，无线帧偏移(y)，无线帧内的子帧编号(Subframe number)，子帧内的起始符号(Starting symbol)，子帧内PRACH时隙的个数(Number of PRACH slots within a subframe)，PRACH时隙内PRACH时机的个数(number of time-domain PRACH occasions within a PRACH slot)和PRAC时机持续时间(PRACH duration)。通过指示的这些信息，就可以确定PRACH资源的时、频、码信息。In the Rel-15 NR technology, the RACH resources configured for the access UE are defined, including 256 configurations. The RACH resource configuration information used by the cell is indicated to the accessing UE in the system message. The RACH resource configuration for the unpaired spectrum of FR2 is shown in Table 1 below. Among them, each RACH resource configuration includes the preamble format, the radio frame period (x) where the RACH timing is located, the radio frame offset (y), the subframe number (Subframe number) in the radio frame, and the subframe The starting symbol in the frame (Starting symbol), the number of PRACH slots within a subframe (Number of PRACH slots within a subframe), and the number of PRACH opportunities within a PRACH slot (number of time-domain PRACH occasions within a PRACH) slot) and PRAC timing duration (PRACH duration). Through the indicated information, the time, frequency, and code information of the PRACH resource can be determined.

表1Table 1

如图4所示，对于一个IAB基站，它既需要与Parent IAB基站建立backhaul link，也需要为接入UE和child IAB基站提供接入服务。IAB基站需要接收接入UE和child基站的RACH，也需要通过发送RACH与Parent基站建立backhaul link。由于半双工的限制，IAB基站不能同时发送PRACH并且接收PRACH。所以IAB基站配置的用于backhaul link的RACH资源和为IAB基站服务的UE或者child基站配置的RACH资源需要在时间上分开。As shown in Figure 4, for an IAB base station, it not only needs to establish a backhaul link with the parent IAB base station, but also needs to provide access services for the access UE and the child IAB base station. The IAB base station needs to receive the RACH that accesses the UE and the child base station, and also needs to establish a backhaul link with the parent base station by sending the RACH. Due to the limitation of half-duplex, the IAB base station cannot transmit and receive PRACH at the same time. Therefore, the RACH resource configured by the IAB base station for backhaul link and the RACH resource configured by the UE or child base station serving the IAB base station need to be separated in time.

目前，在现有RACH资源配置中引入一个时域的偏移，使得新的RACH资源与现有的RACH资源不在相同的时间。例如，在现有的RACH资源配置的基础上定义一个无线帧偏移、子帧偏移或者时隙偏移，从而产生用于IAB基站的RACH资源。例如，对于表1中的RACH configuration Index＝66，定义一个时隙偏移slot offset＝1，得到一个新的RACH configuration Index＝66b，如表2所示。Currently, a time domain offset is introduced into the existing RACH resource configuration, so that the new RACH resource and the existing RACH resource are not at the same time. For example, a radio frame offset, subframe offset, or time slot offset is defined on the basis of the existing RACH resource configuration, thereby generating RACH resources for the IAB base station. For example, for RACH configuration Index=66 in Table 1, define a slot offset = 1, and obtain a new RACH configuration Index=66b, as shown in Table 2.

表2Table 2

请参见图5，图5为本申请实施例提供的一种资源确定方法的流程示意图，该资源确定方法应用于IAB网络设备，该方法包括以下步骤：Please refer to FIG. 5. FIG. 5 is a schematic flowchart of a method for determining a resource according to an embodiment of the application. The method for determining a resource is applied to an IAB network device. The method includes the following steps:

步骤501：IAB网络设备确定第一RACH configuration信息和第二RACH configuration信息。Step 501: The IAB network device determines the first RACH configuration information and the second RACH configuration information.

具体地，步骤501的具体实现方式有：IAB网络设备基于第三RACH configuration信息确定第一RACH configuration信息和第二RACH configuration信息。Specifically, the specific implementation of step 501 is as follows: the IAB network device determines the first RACH configuration information and the second RACH configuration information based on the third RACH configuration information.

其中，第三RACH configuration信息是现有的RACH configuration信息，如表1中的256种中的其中一个。第一RACH configuration信息和第二RACH configuration信息是通过将第三RACH configuration信息进行时域偏移得到的。其中，第一RACH configuration信息对应的偏移值与第二RACH configuration信息对应的偏移值不同。第一RACH configuration信息对应的偏移值具体多少可根据实际情况确定，第二RACH configuration信息对应的偏移值具体多少可根据实际情况确定。Among them, the third RACH configuration information is the existing RACH configuration information, such as one of the 256 types in Table 1. The first RACH configuration information and the second RACH configuration information are obtained by time-domain offsetting the third RACH configuration information. Wherein, the offset value corresponding to the first RACH configuration information is different from the offset value corresponding to the second RACH configuration information. The specific offset value corresponding to the first RACH configuration information may be determined according to actual conditions, and the specific offset value corresponding to the second RACH configuration information may be determined according to actual conditions.

其中，第三RACH configuration信息是IAB网络设备基于接收到的***消息确定的。具体有，该***消息中携带有RACH configuration Index，然后IAB网络设备基于表1和该RACH configuration Index既可确定第三RACH configuration信息。Among them, the third RACH configuration information is determined by the IAB network device based on the received system message. Specifically, the system message carries the RACH configuration Index, and then the IAB network device can determine the third RACH configuration information based on Table 1 and the RACH configuration Index.

其中，RACH configuration信息包括前导格式，PRACH时机所在的无线帧的周期，无线帧偏移，无线帧内的子帧编号，子帧内的起始符号，子帧内PRACH时隙的个数，PRACH时隙内PRACH时机的个数和PRACH时机持续时间。Among them, the RACH configuration information includes the preamble format, the period of the radio frame where the PRACH timing is located, the radio frame offset, the subframe number in the radio frame, the start symbol in the subframe, the number of PRACH slots in the subframe, and PRACH The number of PRACH opportunities and the duration of PRACH opportunities in the time slot.

步骤502：IAB网络设备基于所述第一RACH configuration信息确定所述IAB网络设备的分布单元(Distributed Units，DU)的第一随机接入信道时机集合。Step 502: The IAB network device determines a first random access channel timing set of distributed units (Distributed Units, DU) of the IAB network device based on the first RACH configuration information.

步骤503：IAB网络设备基于所述第二RACH configuration信息确定所述IAB网络设备的移动终结(Mobile-Termination，MT)的第二随机接入信道时机集合。Step 503: The IAB network device determines a second random access channel timing set of Mobile-Termination (MT) of the IAB network device based on the second RACH configuration information.

具体地，第三RACH configuration信息是现有的RACH configuration信息，如表1中的256种中的其中一个。由于RACH configuration信息包含了前导格式，PRACH时机所在的无线帧的周期，无线帧偏移，无线帧内的子帧编号，子帧内的起始符号，子帧内PRACH时隙的个数，PRACH时隙内PRACH时机的个数和PRACH时机持续时间，通过RACH configuration信息即可确定了一个随机接入时机的集合。Specifically, the third RACH configuration information is existing RACH configuration information, such as one of the 256 types in Table 1. Since the RACH configuration information includes the preamble format, the period of the radio frame where the PRACH timing is located, the radio frame offset, the subframe number in the radio frame, the start symbol in the subframe, the number of PRACH slots in the subframe, and PRACH The number of PRACH opportunities in the time slot and the duration of PRACH opportunities can be determined by the RACH configuration information to determine a set of random access opportunities.

另外，由于通过对第三RACH configuration信息进行时域偏移得到第一RACH configuration信息和第二RACH configuration信息，因此通过第一RACH configuration信息和第二RACH configuration信息可分别确定两个随机接入时机的集合。In addition, since the first RACH configuration information and the second RACH configuration information are obtained by time-domain offsetting the third RACH configuration information, the first RACH configuration information and the second RACH configuration information can respectively determine two random access occasions Collection.

步骤504：IAB网络设备确定所述第一随机接入信道时机集合与所述第二随机接入信道时机集合重叠的目标随机接入信道时机。Step 504: The IAB network device determines a target random access channel opportunity where the first random access channel timing set overlaps with the second random access channel timing set.

其中，目标随机接入信道时机是第一随机接入信道时机集合和与所述第二随机接入信道时机集合在时间轴上出现重叠的任意一个随机接入信道时机。Wherein, the target random access channel timing is the first random access channel timing set and any random access channel timing that overlaps with the second random access channel timing set on the time axis.

步骤505：IAB网络设备基于所述IAB网络设备的DU的资源配置，确定所述目标随机接入信道时机属于所述IAB网络设备的DU，或是属于所述IAB网络设备的MT。Step 505: The IAB network device determines that the target random access channel opportunity belongs to the DU of the IAB network device or the MT of the IAB network device based on the resource configuration of the DU of the IAB network device.

其中，一个IAB网络设备包括两个逻辑功能单元，即IAB网络设备的DU和IAB网络设备的MT。其中，DU用于来自child IAB基站的backhaul link和来自UE的access link的接收和发送，MT用于IAB网络设备与其parent IAB网络设备的backhaul link的发送和接收。Among them, an IAB network device includes two logical function units, namely the DU of the IAB network device and the MT of the IAB network device. Among them, DU is used to receive and send backhaul links from child IAB base stations and access links from UE, and MT is used to send and receive backhaul links between IAB network equipment and its parent IAB network equipment.

其中，所述IAB网络设备的DU的资源配置可以是所述IAB网络设备的父IAB网络设备配置的，也可以是其他控制节点配置的。所述IAB网络设备的DU的资源配置包括DU使用的所有资源的配置，即包括DU使用的所有资源的资源属性的配置和/或DU使用的所有资源的资源类型的配置Wherein, the resource configuration of the DU of the IAB network device may be configured by the parent IAB network device of the IAB network device, or may be configured by other control nodes. The resource configuration of the DU of the IAB network device includes the configuration of all resources used by the DU, that is, the configuration of resource attributes of all resources used by the DU and/or the configuration of resource types of all resources used by the DU

其中，所述IAB网络设备的DU的资源配置包括所述IAB网络设备的DU使用的资源属性和/或资源类型，所述IAB网络设备的DU使用的资源属性包括硬资源(Hard)、软资源(Soft)、无属性(NA)中的任意一种，所述软资源包括可用软资源、不可用软资源中的任意一种，所述资源类型包括上行、下行、灵活(flexible)中的任意一种。Wherein, the resource configuration of the DU of the IAB network device includes resource attributes and/or resource types used by the DU of the IAB network device, and the resource attributes used by the DU of the IAB network device include hard resources (Hard) and soft resources. Any one of (Soft) and no attribute (NA), the soft resource includes any one of available soft resources and unavailable soft resources, and the resource type includes any of uplink, downlink, and flexible (flexible) One kind.

其中，可用软资源或不可用软资源可以是所述IAB网络设备的父IAB网络设备指示的，或是其他控制节点指示的。The available soft resource or unavailable soft resource may be indicated by the parent IAB network device of the IAB network device, or indicated by other control nodes.
