Abstract
In the present disclosure, a first node performs buffer status reporting including information regarding a total amount of UL data. The first node determines the total amount of UL data for the buffer status reporting based on an amount of UL data for which the UL resources are actually allocated to the second node by the first node.
Claims6
A method for performing buffer status reporting (BSR) by a first node in a wireless communication system, the method comprising:
- triggering a pre-BSR;
- and
- transmitting a buffer status report to a parent node of the first node based on the triggered pre-BSR,
- wherein triggering the pre-BSR comprises:
- triggering the pre-BSR based on providing scheduling information to a child node of the first node,
- wherein the first node is an integrated access and backhaul (IAB) node, the child node of the first node is an IAB node or UE for which transmission is scheduled by the first node, and the parent node of the first node is an IAB node that schedules transmission for the first node, and
- wherein the buffer status report includes information regarding a total amount of data that is determined based on buffer sizes received from child nodes of the first node for a time duration configured by the parent node starting from a time point indicated by the parent node.
A device for a first node of performing buffer status reporting (BSR) in a wireless communication system, the device comprising:
- at least one processor;
- and
- at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
- triggering a pre-BSR;
- and
- transmitting a buffer status report to a parent node of the first node based on the triggered pre-BSR,
- wherein triggering the pre-BSR comprises:
- triggering the pre-BSR based on providing scheduling information to a child node of the first node,
- wherein the first node is an integrated access and backhaul (IAB) node, the child node of the first node is an TAB node or UE for which transmission is scheduled by the first node, and the parent node of the first node is an TAB node that schedules transmission for the first node, and
- wherein the buffer status report includes information regarding a total amount of data that is determined based on buffer sizes received from child nodes of the first node for a time duration configured by the parent node starting from a time point indicated by the parent node.
A non-transitory computer readable storage medium embodied on a computer readable medium, comprising at least one program code that causes at least one processor to perform operations comprising:
- triggering, at a first node, a pre-buffer status reporting (BSR);
- and
- transmitting a buffer status report to a parent node of the first node based on the triggered pre-BSR,
- wherein triggering the pre-BSR comprises:
- triggering the pre-BSR based on providing scheduling information to a child node of the first node,
- wherein the first node is an integrated access and backhaul (IAB) node, the child node of the first node is an IAB node or UE for which transmission is scheduled by the first node, and the parent node of the first node is an IAB node that schedules transmission for the first node, and
- wherein the buffer status report includes information regarding a total amount of uplink (UL) data that is determined based on buffer sizes received from child nodes of the first node for a time duration configured by the parent node starting from a time point indicated by the parent node.
