Claim 5:
6. An information transmission method of an Integrated Access and Backhaul (IAB) link, comprising:
transmitting, by a first IAB node of the IAB link, flow control information to a second IAB node of the IAB link via a logical channel of a plurality of logical channels between the first IAB node and the second IAB node using a protocol data unit (PDU),
wherein the flow control information comprises desired buffer size information for the logical channel between the first IAB node and the second IAB node and a logical channel identifier (LCD) corresponding to the logical channel identified from the plurality of logical channels,
wherein the desired buffer size information comprises a desired buffer size corresponding to the logical channel identified by the LCID from the plurality of logical channels between the first IAB node and the second IAB node, and
wherein the second IAB node is an IAB parent node to the first IAB node that is a hop away from the first IAB node in a plurality of hops in the IAB link.
