Multiple timers for effective reordering

An apparatus for wireless communications at a wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive control signaling indicating a time duration of a first packet data convergence protocol (PDCP) reordering timer;
• receive a plurality of packets having a sequential order;
• initiate the first PDCP reordering timer based at least in part on a first time stamp corresponding to unsuccessful decoding of a first packet in the sequential order;
• and
• initiate, subsequent to expiration of the first PDCP reordering timer, a second PDCP reordering timer based at least in part on a second time stamp corresponding to unsuccessful decoding of a second packet in the sequential order, the second PDCP reordering timer being shorter than the first PDCP reordering timer.

A method for wireless communications at a wireless device, comprising:

• receiving a first subset of a plurality of packets having a sequential order via a first radio bearer of a split radio bearer that operates in accordance with a first radio access technology and a second subset of the plurality of packets via a second radio bearer of the split radio bearer that operates in accordance with the first radio access technology or a second radio access technology;
• initiating a first packet data convergence protocol (PDCP) reordering timer based at least in part on a first time stamp corresponding to unsuccessful decoding of a first packet in the sequential order;
• and
• initiating, prior to expiration of the first PDCP reordering timer, a second PDCP reordering timer based on a second time stamp corresponding to unsuccessful decoding of a second packet in the sequential order.
