Buffer status reporting and logical channel prioritization in multiflow operation

A method for wireless communications performed by a first cell of a wireless communications network, comprising:

• establishing a first component carrier for communication with a user equipment (UE);
• determining an uplink service ratio associated with the UE for allocating resources of the first cell and a second cell in communication with the UE over a second component carrier;
• receiving an uplink report indicating an amount of uplink data available at the UE for transmission to the first cell;
• and
• scheduling uplink resources of the first component carrier for the UE based at least in part on the uplink report.

A method of wireless communication by a user equipment (UE) in communication with a first cell and a second cell, comprising:

• establishing a first component carrier at the UE associated with the first cell;
• establishing a second component carrier at the UE associated with the second cell while maintaining the first component carrier;
• determining a set of logical channel groups having available data for uplink transmission from the UE;
• detecting that a first buffer status reporting condition has occurred;
• determining a first buffer status value based at least in part on a total amount of the available data for the set of logical channel groups upon occurrence of the first buffer status reporting condition;
• comparing the total amount of the available data to a threshold;
• and
• reporting the first buffer status value to the first cell, the second cell, or both based on the comparison.

A communications device for communication with a first cell and a second cell of a wireless communications network, comprising:
