Methods for pre-emptive buffer status reporting for wireless access backhauling

Abstract

The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a wireless access backhaul (WAB) node in a wireless communication system is provided. The method includes identifying a condition at the WAB node, and in response to identifying the condition, transmitting, to a second network node over a backhaul connection, scheduling assistance information, wherein the condition is at least one of determining, based on a buffer status report (BSR) received from a first network node, that data will have to be transmitted over the backhaul connection, determining, based on identifying a procedure being performed, to be performed, or having been performed by at least one of the first network node, the WAB node or the second network node, that data will have to be transmitted by the WAB node over the backhaul connection, identifying that an uplink (UL) grant is provided to a user equipment (UE) in response to a BSR that indicates a logical channel not associated with a system resource block (SRB), identifying that a BSR is received from a UE and the BSR indicates a logical channel not associated with an SRB, identifying a trigger from the radio resource control (RRC) layer, or identifying that a message will be sent over at least one of the NGAP or Xn interfaces.

Dependencies are inferred from the claim text.
