Methods and apparatuses for efficient delay status reporting in mobile communications

Abstract

Various solutions for efficient delay status reporting (DSR) in mobile communications are described. An apparatus may receive a configuration included in a MAC-CellGroupConfig information element (IE) of a radio resource control (RRC) signaling from a network node. The configuration may include a remaining time threshold for triggering a DSR procedure for one or more logical channels within a logical channel group (LCG), and a plurality of reporting thresholds on remaining time for reporting delay status information of the LCG. Then, the apparatus may trigger the DSR procedure for the one or more logical channels based on the remaining time threshold. Responsive to triggering the DSR procedure, the apparatus may transmit a DSR medium access control (MAC) control element (CE) to the network node, which includes a plurality of entries of delay status information of the LCG, each entry is associated with one of the plurality of reporting thresholds.
