Techniques for wireless communication at a user equipment (UE) are described. One method includes receiving, from a first access point using a first radio access technology (RAT), a configuration associated with a logical traffic connection, in which the configuration includes at least one parameter for communicating data associated with the logical traffic connection via a second access point associated with a second RAT; determining a buffer reporting value associated with the logical traffic connection based at least in part on a total amount of data buffered in a packet data convergence protocol (PDCP) queue associated with the logical traffic connection and the at least one parameter; and transmitting a buffer status report (BSR) including the buffer reporting value to the first access point.
