Expediting repetition of an unanswered poll for automatic repeat request (arq) feedback

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to
• transmit a poll to a peer protocol entity to trigger status reporting at the peer protocol entity;
• start a timer with a duration based on whether at least one predefined condition is met, wherein the at least one predefined condition depends at least on a value of a sequence number (SN) of a protocol data unit (PDU) in which the poll is transmitted;
• and
• re-transmit a poll when the timer expires.

A computer program, embodied on a non-transitory computer readable medium, the computer program configured to control a processor to perform a process, comprising:

• transmitting a poll to a peer protocol entity to trigger status reporting at the peer protocol entity;
• starting a timer with a duration that is based on whether at least one predefined condition is met, wherein the at least one predefined condition depends at least on a value of a sequence number (SN) of a protocol data unit (PDN) in which the poll is transmitted;
• and
• re-transmitting a poll when the timer expires.
