Techniques for poll bit trigger enhancement in a wireless communication system

An apparatus for wireless communication at a user equipment (UE), comprising:

• a transceiver;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to execute the instructions to:
• determine whether a count of packet data unit (PDU) without POLL associated with a current PDU sequence satisfies a threshold for maximum PDUs without POLL;
• determine whether a total transmission queue memory exceeds an uplink transmission queue memory threshold;
• generate a POLL bit based on a determination that the PDU without POLL count associated with the current PDU without POLL in-sequence satisfies the threshold for maximum PDUs without POLL and the total transmission queue memory exceeds the threshold for uplink transmission queue memory;
• and
• transmit, to a network entity, the current PDU with the POLL bit.

An apparatus for wireless communication at a network entity, comprising:

• a transceiver;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to execute the instructions to:
• receiving, from a user equipment (UE), a current packet data unit (PDU) with a POLL bit configured to trigger reporting of a status PDU at a peer acknowledgement mode (AM) radio link control (RLC) entity associated with the network entity;
• and
• transmitting, to the UE, the status PDU in response to receiving the current PDU with the POLL bit, the status PDU configured to acknowledge or negatively acknowledge one or more received RLC service data unit (SDU) segments.
