Abstract
For routing Packet Data Converge Protocol (PDCP) Protocol Data Units (PDU), a processor detects a split bearer configuration for a mobile device. In response to detecting the split bearer configuration, the processor routes PDCP PDU in a Radio Link Control (RLC)/Medium Access Control (MAC) for the at least two cell groups.
Claims15
A method comprising:
- detecting, by use of a processor, two Radio Link Control (RLC) entities associated with a first Packet Data Converge Protocol (PDCP) and an amount of data available for transmission exceeding a data split threshold;
- in response to detecting both the two RLC entities and the amount of data available for transmission exceeding the data split threshold, routing, by use of a processor, a first PDCP Protocol Data Unit (PDU) to a first RLC entity of at least two RLC entities, the first RLC entity belonging to a first cell group and a second RLC entity belonging to a second cell group before receiving a request from the first RLC entity and the second RLC entity;
- starting a timer in response to routing the first PDU to the first RLC entity;
- and
- routing the first PDU to the second RLC entity of the at least two associated RLC entities in response to the timer expiring before the first PDU is submitted from a first Media Access Control (MAC) for the first cell group to a lower layer for transmission.

An apparatus comprising:
- a processor performing:
- detecting two Radio Link Control (RLC) entities associated with a first Packet Data Converge Protocol (PDCP) and an amount of data available for transmission exceeding a data split threshold;
- in response to detecting both the two entities and the amount of data available for transmission exceeding the data split threshold, routing a first PDCP Protocol Data Unit (PDU) to a first RLC entity of at least two RLC entities, the first RLC entity belonging to a first cell group and a second RLC entity belonging to a second cell group before receiving a request from the first RLC entity and the second RLC entity;
- starting a timer in response to routing the first PDU to the first RLC entity;
- and
- routing the first PDU to the second RLC entity of the at least two associated RLC entities in response to the timer expiring before the first PDU is submitted from a first Media Access Control (MAC) for the first cell group to a lower layer for transmission.

A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
- detecting two Radio Link Control (RLC) entities associated with a first Packet Data Converge Protocol (MCP) and an amount of data available for transmission exceeding a data split threshold;
- in response to detecting both the two RLC entities and the amount of data available for transmission exceeding the data split threshold, routing a first PDCP Protocol Data Unit (PDU) to a first RLC entity of at least two RLC entities, the first RLC entity belonging to a first cell group and a second RLC entity belonging to a second cell group before receiving a request from the first RLC entity and the second RLC entity;
- starting a timer in response to routing the first PDU to the first RLC entity;
- and
- routing the first PDU to the second RLC entity of the at least two associated RLC entities in response to the timer expiring before the first PDU is submitted from a first Media Access Control (MAC) for the first cell group to a lower layer for transmission.
