Problems solved by technology

[0004] The poor link status or congestion of the backhaul link or the access link may cause the link communication between the IAB node and a certain upper-level node to be interrupted, which may involve handover across the host base station. How to implement the IAB node The resource allocation of cross-host base station handover is a problem that needs to be solved

example 1

[0180] Example 1, see Figure 12 The flow diagram of the configuration method of the exemplary IAB node provided in the present application embodiment. In the description below, the method is applied to Figure 9 ~ 10 The communication system shown is an example. In addition, the method is performed by the IAB node, the source IAB host and the target IAB host. It should be noted that the embodiment of the present application is only passed Figure 9 and Figure 10 The communication system is an example, which is not limited to this scene. This process is described below.

[0181] S1201, the IAB node transmits a measurement report to the source IAB host, and the source IAB host receives the measurement report, which is used to indicate the results of the IAB node to measure multiple alternative target IAB hosts.

[0182] It should be understood that the source IAB host can configure measurement configuration for the IAB node, which is measured related information, may include, for exam...

Abstract

The invention discloses an IAB node configuration method and a communication device. The method comprises the steps that a target IAB host receives first information from a source IAB host and sends first configuration information to the source IAB host; the IAB node comprises an MT and a DU, the first configuration information is determined according to the first information and is used for indicating the transmission direction of a time domain resource configured for the MT by the target IAB host, and the first information is used for indicating one or more of the following four kinds of information: when the MT is supported or not supported to receive data, the DU sends the data; the DU receives the data while supporting or not supporting the MT to receive the data; the DU sends the data while supporting or not supporting the MT to send the data; the DU receives the data while supporting or not supporting the MT to send the data. The first information can be duplex capability information, the first configuration information takes the first information as the premise, and in the cross-host switching process of the IAB node, the transceiving conflict between the DU and the MT can be avoided.

Description

Technical field [0001] The present application relates to the field of communication technology, and more particularly to a configuration method and a communication device of an IAB node. Background technique [0002] In order to improve network capacity and override, a relay node supporting wireless return transmission is proposed to implement deployment of intensive networks. The node that supports the relay function is simply referred to as the relay node, and the relay node provides a function and service similar to the universal base station to the terminal of the universal base station. The communication link between the relay node and the terminal is called the access chain. Access Link. The relay node accesss a base station that serves its base station through the wireless interface, and the base station is called another relay node or the host base station, the relay node, and the relay node, and in the middle The wireless interface link between the node and the host bas...
