Techniques for managing uplink transmissions in a shared radio frequency spectrum band and a dedicated radio frequency spectrum band

A method for wireless communication at a user equipment (UE), comprising:

• communicating on a first uplink carrier in a dedicated radio frequency spectrum band and a second uplink carrier in a shared radio frequency spectrum band;
• maintaining a prioritized bit rate (PBR) for each of a plurality of logical channels to determine a nominal scheduling priority of the plurality of logical channels;
• receiving an uplink grant for the first uplink carrier in the dedicated radio frequency spectrum band;
• and
• mapping at least a portion of data associated with a logical channel of the plurality of logical channels to resources of the uplink grant according to a logical channel priority applied independently of the nominal scheduling priority.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• the processor and memory configured to:
• maintain a first prioritized bit rate (PBR) and a second PBR for each of one or more logical channels, the first PBR associated with transmissions in a shared radio frequency spectrum band and a dedicated radio frequency spectrum band, and the second PBR associated with transmissions in the dedicated radio frequency spectrum band;
• and
• map at least a portion of data associated with a logical channel of the one or more logical channels to resources of one or more uplink grants according to the first PBR for the logical channel and the second PBR for the logical channel.
