1. A method for managing uplink (UL) data transport for a fifth generation (5G) wireless device, the method comprising:
by the 5G wireless device:
while i) using a split radio bearer across a master cell group (MCG) and a secondary cell group (SCG) of a wireless network, ii) a latency sensitive application session is active with data separable into multiple priorities, iii) a performance metric for the SCG falls below a first performance threshold, and iv) a mobility state indicates the 5G wireless device is stationary:
sending, to the wireless network, at least one buffer status report (BSR) request message for the UL data transport via the MCG;
receiving, from the wireless network responsive to the at least one BSR request message, resource allocation grants for the UL data transport via the MCG; and
prioritizing and sending higher priority data of the latency sensitive application session before sending any lower priority data using the resource allocation grants,
wherein the first performance threshold exceeds a measurement reporting threshold indicated by the wireless network.
