Various solutions for logical channel prioritization (LCP) enhancements in mobile communications are described. An apparatus may select a plurality of logical channels for an uplink (UL) grant. The apparatus may allocate resources of the UL grant to one or more of the logical channels in a decreasing priority order. Each of the one or more logical channels carries delay-critical data or is associated with a positive number of tokens. Then, the apparatus may decrement the positive number of tokens for each of the one or more logical channels by a total size of medium access control (MAC) service data units (SDUs) served to the corresponding logical channel. After that, the apparatus may multiplex the MAC SDUs in a MAC protocol data unit (PDU) for transmission on the UL grant to a network node.
