Abstract
A method for providing a Buffer Status Report (BSR) in a network is provided. The method comprises selecting a format of the BSR from among at least two BSR formats. The format of the BSR is selected based on one or more predetermined criteria. The predetermined criteria may comprise one or more of: a number of configured LCGs; a number of LCGs of a certain minimum priority; and/or a required level of BSR granularity.
Claims25
A method performed by a child node of an integrated access and backhaul (IAB) for providing a buffer status report (BSR) in a network, the method comprising:
- receiving, from a parent node of the IAB, information on an identity (ID) of a logical channel group (LCG) via a radio resource control (RRC) signaling, in case that a number of LCGs to which logical channels are allocated is greater than a first maximum number of LCGs, wherein the information on the ID of the LCG is associated with a second maximum number of LCGs being 256;
- and
- selecting a format of the BSR from among at least two BSR formats,
- wherein the format of the BSR is selected based on a number of LCGs having data available for transmission and the information on the ID of the LCG.
A method performed by a parent node of an integrated access and backhaul (IAB) in a wireless communication system, the method comprising:
- identifying whether a number of logical channel groups (LCGs) to which logical channels are allocated is greater than a first maximum number of LCGs;
- and
- transmitting, to a child node of the IAB, information on an identity (ID) of a LCG, via a radio resource control (RRC) signaling, in case that the number of LCGs is greater than or equal to the first maximum number of LCGs,
- wherein a format of a buffer status report (BSR) is selected from among at least two BSR formats, based on a number of LCGs having data available for transmission and the information on the ID of the LCG, and
- wherein the information on the ID of the LCG is associated with a second maximum number of LCGs being 256.
A equipment child node of an integrated access and backhaul (IAB) in a network comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive, from a parent node of the IAB, information on an identity (ID) of a logical channel group (LCG) via a radio resource control (RRC) signaling, in case that a number of LCGs to which logical channels are allocated is greater than a first maximum number of LCGs, wherein the information on the ID of the LCG is associated with a second maximum number of LCGs being 256, and
- select a format of a buffer status report (BSR) from among at least two BSR formats,
- wherein the format of the BSR is selected based on a number of LCGs having data available for transmission and the information on the ID of the LCG.
A parent node of an integrated access and backhaul (IAB) in a wireless communication system, the parent node comprising:
- a transceiver;
- and
- at least one processor configured to:
- identify whether a number of logical channel groups (LCGs) to which logical channels are allocated is greater than a first maximum number of LCGs, and
- transmit, to a child node of the IAB, information on an identity (ID) of a LCG, via a radio resource control (RRC) signaling, in case that the number of LCGs is greater than the first maximum number of LCGs,
- wherein a format of a buffer status report (BSR) is selected from among at least two BSR formats, based on a number of LCGs having data available for transmission and the information on the ID of the LCG, and
- wherein the information on the ID of the LCG is associated with a second maximum number of LCGs being 256.
