Example Embodiment

[0037] Example 1:

[0038] In order to solve the sending of data packets in the IAB scenario, this embodiment provides an information processing method in an IAB network, such as image 3 As shown, the information processing method in the IAB network includes:

[0039] S301. Obtain a first data packet from the access and return first IAB node.

[0040] In this embodiment of the present invention, the first IAB node obtains the first data packet, and the first data packet may be an RRC message sent by the first IAB node to receive the UE, or an RRC message generated by the first IAB node's own MT, or the first IAB node. F1AP messages generated by the IAB node's own DU.

[0041] It is worth noting that after the first IAB node acquires the first data packet, an adaptation layer header can also be added to the first data packet, and the adaptation layer header includes at least one of the following information: target node information; IAB node identification information; the ...

Example Embodiment

[0045] Embodiment 2:

[0046]When the ingress data rate on the IAB node is greater than the egress data rate, the buffer overflow will be caused, which will cause congestion in the IAB network. In order to solve the problem of flow control, this embodiment provides an information processing method in the IAB network. Information processing methods in the IAB network include

[0047] The first IAB node sends flow control information to the parent node.

[0048] In this embodiment of the present invention, the IAB node accessed by the IAB node with the connection identity is called the parent IAB node. The flow control information includes at least one of the following information: one or more bearer identifiers; one or more logical channel identifiers; user equipment UE identifier or node identifier information of the IAB node; required buffer size information; required buffer size information; Data rate desired data rate information; flow control indication. It can be under...

Example Embodiment

[0050] Embodiment three:

[0051] In order to realize the resource coordination of the IAB, this embodiment provides an information processing method in an IAB network, and the information processing method in the IAB network includes:

[0052] The IAB host donor CU sends downlink information to the IAB host donor DU;

[0053] Or, the IAB host donor CU sends downlink information to the IAB node;

[0054] Or, the parent IAB node forwards the downlink information to the IAB node.

[0055] The downlink information message is an RRC message or an F1AP message.

[0056] In this embodiment of the present invention, the IAB host donor DU can be directly connected to the IAB node, or it can be connected to the IAB node through other intermediate IAB nodes. Therefore, when the IAB host donor CU sends downlink information to the IAB node, it can be the IAB host donor. The CU sends downlink information to the IAB host donor DU, and forwards the downlink information to the IAB node thr...

Abstract

The embodiment of the invention provides an information processing method in an IAB network, an IAB and a computer storage medium. The method comprises the following steps: a first data packet is acquired through a first IAB node; the first IAB node sends the first data packet to an IAB host, i.e., the first IAB node realizes forwarding of the data packet; flow control information is sent to a father node through an IAB node, that is, the flow control information is sent, so that congestion in an IAB network is relieved; through the configuration of the IAB host, the resource coordination in the IAB network is realized.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of communication technology, and specifically, relate to but are not limited to an information processing method in an IAB network, an IAB, and a computer storage medium. Background technique [0002] As the fifth-generation mobile communication network, 5G network has a peak theoretical transmission speed of tens of Gb per second, which is hundreds of times faster than that of 4G network. The reason why 5G can achieve high transmission speed is the use of millimeter waves. Millimeter waves refer to electromagnetic waves with wavelengths on the order of millimeters, and their frequencies are between 30 GHz and 300 GHz. One of the characteristics of the millimeter wave frequency band is that it has a large attenuation in the air and a weak diffraction ability. For this reason, integrated access and backhaul links (IAB, integrated access and backhaul links) technology is pr...
