FIG. 15 is an example of applying option 2 of method 2 in case 3. The SR includes two different fields for separately indicating TTI duration need and numerology need. In former part, the data of logical channel 1 and the data of logical channel 2 triggers uplink BSR independently. The SR transmission for each data arrival event is set in different values according to the logical channel configuration. In latter part, since the new MAC CE also has corresponding logical channel configuration, the SR transmission for forwarding new MAC CE shall be set accordingly.
FIG. 16 is an example of applying option 1 of method 2 in case 3. In this example, the UE will select combination of TTI and numerology for delivering the new MAC CE as soon as possible. Hence, the UE set fields in SR to 120 khz SCS and TTI for urgent service.
FIG. 17 is an example of applying option 1 of method 1 in case 3. In this example, the UE will trigger and transmit SR of SR configuration related to the largest numerology for the new MAC CE. Hence, the UE transmit SR according to SR configuration 1.
