Methods and apparatuses for adaptive logical channel prioritization in mobile communications

An apparatus, comprising:

• a transceiver which, during operation, wirelessly communicates with a network node;
• and
• a processor communicatively coupled to the transceiver such that, during operation, the processor performs operations comprising:
• selecting a plurality of logical channels for an uplink (UL) grant, wherein each of the plurality of logical channels is configured with a priority;
• applying an additional priority for at least one of the plurality of logical channels in an event that at least one condition is met, wherein the at least one condition comprises a first condition that the at least one of the plurality of logical channels carries data with a remaining time of an associated packet data convergence protocol (PDCP) discard timer less than a first threshold;
• allocating resources of the UL grant to one or more of the plurality of logical channels in a decreasing priority order determined based on the additional priority being applied, wherein each of the one or more of the plurality of logical channels is associated with a positive number of tokens;
• and
• performing, via the transceiver, a new transmission to the network node based on the allocation of the resources of the UL grant.
