Problems solved by technology

For wired backhaul, in scenarios where a large number of TPs are densely deployed (such as dense neighborhoods), the cost of wired backhaul may be unacceptably high considering the deployment or lease costs of cables or optical fibers, site selection and maintenance costs, etc.
Even if wired backhaul is laid, due to the dense deployment scenario, the number of users served by each node is small, the load fluctuates greatly, or due to energy saving/interference control, some nodes will be dynamically turned on or off, and the backhaul link is often idle status, and the use

Embodiment 1

[0043] In this embodiment, a method for processing IAB node information in an integrated access backhaul IAB network is provided. Figure 4 It is the flow of the method for processing the IAB node information in the integrated access backhaul IAB network according to the embodiment of the present invention Figure 1 ,Such as Figure 4 As shown, the process includes the following steps:

[0044] Step S402, the first IAB node in the IAB network is switched from the third IAB node and / or the connection is reestablished to the fourth IAB node;

[0045] Step S404, the second IAB node receives the notification information sent by the first IAB node;

[0046] Step S406, the second IAB node notifies the user terminal UE connected to the second IAB of the notification information;

[0047] Wherein, the notification information includes at least one of the following: notification information for notifying a connection switching event and / or a connection reestablishment event, and ind...

Embodiment 2

[0060] In this embodiment, a method for processing IAB node information in an integrated access backhaul IAB network is provided. Image 6 It is the flow of the method for processing the IAB node information in the integrated access backhaul IAB network according to the embodiment of the present invention Figure II ,Such as Image 6 As shown, the process includes the following steps:

[0061] Step S602, after the first IAB node in the IAB network completes the connection switch from the third IAB node to the fourth IAB node connection switch and / or connection reestablishment, the IAB Donor node sends the routing configuration to the IAB node related to the routing update information;

[0062] Step S604, the IAB Donor node receives the routing configuration confirmation information fed back by the relevant IAB node in response to the routing configuration information;

[0063] Wherein, the IAB nodes related to the route update include at least one of the following: a third ...

Embodiment 3

[0075] In this embodiment, a method for processing IAB node information in an integrated access backhaul IAB network is provided, and the process includes the following steps:

[0076] Step S802: After the first IAB node in the IAB network completes connection switching and / or connection reestablishment from the third IAB node to the fourth IAB node, the third IAB node sends downlink data transmission status information to the IAB Donor node;

[0077] Step S804: the third IAB node reads the UE bearer identifier and PDCP SN in each data packet at the Adapt layer.

[0078] Wherein, the downlink data transmission status information may optionally include in this embodiment: the identifier of each UE bearer, information of at least one of the following bearers: the largest PDCP SN number sent, the largest PDCP SN number successfully transmitted, The largest PDCP SN number sent for retransmission and the largest PDCP SN number for successful retransmission;

[0079] Wherein, the i...

Abstract

The invention provides a method and device for processing IAB node information in an IAB network, and the method comprises the steps that a second IAB node receives notification information transmitted by a first IAB node; wherein the notification information comprises at least one of the following information: notification information used for notifying a connection switching event and/or a connection reconstruction event, and indication information used for indicating to perform packet data convergence protocol PDCP state reporting. According to the method and the device, the problem that the downlink notification is not solved yet after the IAB node is possibly switched to other nodes due to the change of a wireless link in the related technology is solved, and the effect of ensuring the complete switching of the IAB node is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing IAB node information in an integrated access backhaul IAB network. Background technique [0002] The fifth generation mobile communication technology (5th Generation, referred to as 5G) under research by 3GPP will achieve greater throughput, more user connections, lower latency, higher reliability, and lower power consumption (including network side equipment and user terminals). At present, in the discussion of 3GPP, Integrated Access and Backhaul (IAB) technology has been established as a new research project, and its goal is to enable one or more IAB nodes to serve as the UE of the parent node Connect to the mother node through its local access resources, and form a multi-hop wireless self-backhaul network on this basis to provide a backhaul connection for the local access UE of the IAB node. [0003] In the deployment scenario of 5G UDN (...
