Abstract
Certain aspects of the present disclosure provide a technique for bundling the received service data units (SDU) in a first communication layer to generate a protocol data unit (PDU) to pass to a second communication layer. For example, one or more packet data convergence protocol (PDCP) SDUs may be concatenated to generate a PDCP PDU and be sent to a radio link control (RLC) layer in the transmitter side. Similarly, one or more PDCP SDUs may be extracted from a PDCP PDU in the receiver side.

A method for wireless communications, comprising:
- receiving two or more packet data convergence protocol (PDCP) service data units (SDUs) in a PDCP layer;
- concatenating the PDCP SDUs based on a many to one mapping of PDCP SDUs to a PDCP protocol data unit (PDU), by the PDCP layer, to generate the PDCP PDU before submitting the PDCP PDU to a lower layer;
- and
- sending the PDCP PDU to a radio link control (RLC) layer.
A method for wireless communications, comprising:
- receiving a single packet data convergence protocol (PDCP) protocol data unit (PDU) in a PDCP layer;
- extracting, by the PDCP layer, two or more PDCP service data units (SDUs) from the single PDCP PDU, wherein the two or more PDCP SDUs are concatenated in the single PDCP PDU based on a many to one mapping of PDCP SDUs to the single PDCP PDU before submitting the PDCP PDU to a lower layer;
- and
- sending the two or more PDCP SDUs to a second communication layer for further processing.
An apparatus for wireless communications, comprising:
- means for receiving two or more packet data convergence protocol (PDCP) service data units (SDUs) in a PDCP layer;
- means for concatenating the PDCP SDUs based on a many to one mapping of PDCP SDUs to a PDCP protocol data unit (PDU), by the PDCP layer, to generate the PDCP PDU before submitting the PDCP PDU to a lower layer;
- and
- means for sending the PDCP PDU to a radio link control (RLC) layer.
An apparatus for wireless communications, comprising:
- means for receiving a single packet data convergence protocol (PDCP) protocol data unit (PDU) in a PDCP layer;
- means for extracting, by the PDCP layer, two or more PDCP service data units (SDUs) from the single PDCP PDU, wherein the two or more PDCP SDUs are concatenated in the single PDCP PDU based on a many to one mapping of PDCP SDUs to the single PDCP PDU before submitting the PDCP PDU to a lower layer;
- and
- means for sending the two or more PDCP SDUs to a second communication layer for further processing.
A computer-program product for wireless communications, comprising a non-transitory computer readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for receiving two or more packet data convergence protocol (PDCP) service data units (SDUs) in a PDCP layer;
- instructions for concatenating the SDUs based on a many to one mapping of PDCP SDUs to a PDCP protocol data unit (PDU), by the PDCP layer, to generate a PDCP PDU before submitting the PDCP PDU to a lower layer;
- and
- instructions for sending the PDCP PDU to a radio link control (RLC) layer.
