1. A method of wireless communication at a user equipment (UE), comprising:
generating a POLL bit in response to a determination that a packet data unit (PDU) without POLL count associated with a current PDU sequence satisfies a threshold for maximum PDUs without POLL and a determination that a total transmission queue memory exceeds an uplink transmission queue memory threshold; and
transmitting, to a network entity, the current PDU with the POLL bit.
 
12. A method of wireless communication at network entity, comprising:
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,
the current PDU with the POLL bit being sent in response to the UE determining that a PDU without POLL count associated with the current PDU satisfies a threshold for maximum PDUs without POLL and a total transmission queue memory of the UE exceeds an uplink transmission queue memory threshold.
 
17. 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:
generate a POLL bit in response to a determination that a packet data unit (PDU) without POLL count associated with a current PDU-sequence satisfies a threshold for maximum PDUs without POLL and a determination that a total transmission queue memory exceeds an uplink transmission queue memory threshold; and
transmit, to a network entity, the current PDU with the POLL bit.
 
27. 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,
the current PDU with the POLL bit being sent in response to the UE determining that a PDU without POLL count associated with the current PDU satisfies a threshold for maximum PDUs without POLL and a total transmission queue memory of the UE exceeds an uplink transmission queue memory threshold.
