Abstract
Systems, methods, apparatuses, and computer program products for expediting repetition of an unanswered poll for automatic repeat request (ARQ) feedback are provided. One method includes 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 set based on whether at least one predefined condition is met. 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. The method may further include re-transmitting a poll when the timer expires.
