Techniques for DSR reporting for split bearer operation

Abstract

Various aspects of the present disclosure relate to techniques for delay status reported (DSR) for split bearer operation. An apparatus is configured to associate a packet data convergence protocol (PDCP) entity with a primary radio link control (RLC) entity and at least one secondary RLC entity, indicate a data volume associated with the PDCP entity to a medium access control (MAC) entity for DSR, determine an amount of data available for transmission based on the data volume associated with the PDCP entity and an RLC data volume that is pending for initial transmission in the primary RLC entity and the at least one secondary RLC entity, and indicate an amount of the data volume associated with the PDCP entity to the MAC entity associated with the primary RLC entity for DSR in response to the amount of data available for transmission being less than a threshold.
