AI Technical Summary

Technical Problem

In wireless communication systems, the transmission of buffer status reports (BSRs) can lead to delays and inefficiencies, particularly when the available configured grant (CG) resources are not sufficient to accommodate both pending data and the BSR, resulting in the deprioritization of uplink data transmission.

Method used

The method involves triggering a BSR and constructing a Medium Access Control (MAC) Protocol Data Unit (PDU) that includes all pending data. The BSR is canceled on the last CG resource if the available CG resources within a CG period can accommodate all pending data, and the BSR MAC Control Element (CE) plus its subheader is included in the MAC PDU transmitted on the last CG resource only if sufficient space is available.

Benefits of technology

This approach reduces data transmission delay and avoids the wastage of uplink resources by optimizing the use of CG resources and ensuring that uplink data is transmitted efficiently, even when BSRs are triggered.

Abstract

The present disclosure relates to a method of performing operations for a User Equipment (UE) in a wireless communication system. In particular, the method includes steps of triggering a buffer status report (BSR); constructing at least one Medium Access Control (MAC) Protocol Data Unit (PDU) including all pending data; and transmitting the at least one MAC PDU on at least one available configured grant (CG) resource within a CG period, wherein the triggered BSR is canceled on a last CG resource of the at least one available CG, and wherein, based on the at least one available CG resource within the CG period is able to accommodate all pending data and being sufficient to additionally accommodate a BSR MAC Control Element (CE) plus its subheader, the BSR MAC CE plus its subheader is included in a MAC PDU transmitted on a last CG resource of the at least one available CG resource.
