In an example, the method may include receiving configuration information indicating a remaining time threshold to be used for triggering transmission of a report related to a logical channel group (LCG). The method may include determining that a remaining time for a transmission of one or more PDUs associated with the LCG is below the remaining time threshold. The method may include transmitting the report related to the LCG in a MAC control element (MAC CE) based on at least the remaining time being below the remaining time threshold. In various embodiments, the report may include an indication of (i) the remaining time associated with the LCG and (ii) an amount of data associated with the LCG. ## Claims ### Claim 1 A wireless transmit/receive unit (WTRU) comprising circuitry including any of a processor, a memory, a transmitter and a receiver, the circuitry being configured to: receive configuration information indicating a remaining time threshold to be used for triggering transmission of a report related to a logical channel group (LCG); determine that a remaining time for a transmission of one or more protocol data units (PDUs) associated with the LCG is below the remaining time threshold; and transmit the report related to the LCG in a medium access control (MAC) control element (MAC CE) based on at least the remaining time being below the remaining time threshold, wherein the report comprises an indication of (i) the remaining time associated with the LCG and (ii) an amount of data associated with the LCG. ### Claim 2 (depends on 1) The WTRU of claim 1, wherein the indication of the amount of data associated with the LCG is indicated as an absolute value. ### Claim 3 (depends on 1) The WTRU of claim 1, wherein the indication of the amount of data associated with the LCG is indicated in bytes. ### Claim 4 (depends on 1) The WTRU of claim 1, wherein the indication of the amount of data associated with the LCG is indicated as an index referring to one or more values. ### Claim 5 (depends on 1) The WTRU of claim 1, wherein the configuration information is received in a radio resource control message. ### Claim 6 (depends on 1) The WTRU of claim 1, wherein the configuration information indicates a second threshold to be used for triggering transmission of the report LCG. ### Claim 7 (depends on 6) The WTRU of claim 6, wherein the circuitry is further configured to determine that the amount of data associated with the LCG is above the second threshold, and wherein the circuitry being configured to transmit the report related to the LCG comprises the circuitry being configured to transmit the report related to the LCG based on the determination that amount of data associated with the LCG being above the second threshold. ### Claim 8 A method implemented in a wireless transmit/receive unit (WTRU), the method comprising: receiving configuration information indicating a remaining time threshold to be used for triggering transmission of a report related to a logical channel group (LCG); determining that a remaining time for a transmission of one or more protocol data units (PDUs) associated with the LCG is below the remaining time threshold; and transmitting the report related to the LCG in a medium access control (MAC) control element (MAC CE) based on at least the remaining time being below the remaining time threshold, wherein the report comprises an indication of (i) the remaining time associated with the LCG and (ii) an amount of data associated with the LCG. ### Claim 9 (depends on 8) The method of claim 8, wherein the indication of the amount of data associated with the LCG is indicated as an absolute value. ### Claim 10 (depends on 8) The method of claim 8, wherein the indication of the amount of data associated with the LCG is indicated in bytes. ### Claim 11 (depends on 8) The method of claim 8, wherein the indication of the amount of data associated with the LCG is indicated as an index referring to one or more values. ### Claim 12 (depends on 8) The method of claim 8, wherein the configuration information is received in a radio resource control message. ### Claim 13 (depends on 8) The method of claim 8, wherein the configuration information indicates a second threshold to be used for triggering transmission of the report related to the LCG. ### Claim 14 (depends on 13) The method of claim 13, further comprising determining that the amount of data associated with the LCG is above the second threshold, wherein transmitting the report related to the LCG further comprises transmitting the report related to the LCG based on the amount of data associated with the LCG being above the second threshold.
