A method for wireless communication, comprising: receiving, by a transceiver of a user equipment, a first data stream from a first Medium Access Control, MAC, entity of a first cell and a second data stream from a second MAC entity of a second cell; decoding, by a Radio Link Control, RLC, receiver of the user equipment, RLC Packet Data Units, PDUs, having respective sequence numbers from the first data stream and the second data stream; transmitting an acknowledgment, ACK, for decoded RLC PDUs; detecting a gap in sequence numbers in a sequence number queue wherein the sequence number queue comprises a compilation of sequence numbers from the first data stream and sequence numbers from the second data stream; delaying, at the user equipment, transmitting a not acknowledged, NAK, for the gap in the sequence numbers of the RLC PDUs by starting a NAK delay timer in the user equipment upon detecting the gap; determining, at the user equipment during a delay period after the NAK delay timer has started, whether the NAK delay timer has expired; detecting, at the user equipment during the delay period, whether the gap has been filled, and determining, at the user equipment during the delay period, whether each sequence number of the gap is lower than each of a highest acknowledged sequence number of the first data stream and a highest acknowledged sequence number of the second data stream before the NAK delay timer has expired, and transmitting, by the user equipment, the NAK upon a determination of a first to occur of: the user equipment determining that the NAK delay timer has expired and detecting that the gap has not been filled during the delay period; and the user equipment determining that each sequence number of the gap is lower than each of the highest acknowledged sequence number of the first data stream and the highest acknowledged sequence number of the second data stream before the NAK delay timer has expired. receiving, by a transceiver of a user equipment, a first data stream from a first Medium Access Control, MAC, entity of a first cell and a second data stream from a second MAC entity of a second cell; decoding, by a Radio Link Control, RLC, receiver of the user equipment, RLC Packet Data Units, PDUs, having respective sequence numbers from the first data stream and the second data stream; transmitting an acknowledgment, ACK, for decoded RLC PDUs; detecting a gap in sequence numbers in a sequence number queue wherein the sequence number queue comprises a compilation of sequence numbers from the first data stream and sequence numbers from the second data stream; delaying, at the user equipment, transmitting a not acknowledged, NAK, for the gap in the sequence numbers of the RLC PDUs by starting a NAK delay timer in the user equipment upon detecting the gap; determining, at the user equipment during a delay period after the NAK delay timer has started, whether the NAK delay timer has expired; detecting, at the user equipment during the delay period, whether the gap has been filled, and determining, at the user equipment during the delay period, whether each sequence number of the gap is lower than each of a highest acknowledged sequence number of the first data stream and a highest acknowledged sequence number of the second data stream before the NAK delay timer has expired, and transmitting, by the user equipment, the NAK upon a determination of a first to occur of: the user equipment determining that the NAK delay timer has expired and detecting that the gap has not been filled during the delay period; and the user equipment determining that each sequence number of the gap is lower than each of the highest acknowledged sequence number of the first data stream and the highest acknowledged sequence number of the second data stream before the NAK delay timer has expired. the user equipment determining that the NAK delay timer has expired and detecting that the gap has not been filled during the delay period; and the user equipment determining that each sequence number of the gap is lower than each of the highest acknowledged sequence number of the first data stream and the highest acknowledged sequence number of the second data stream before the NAK delay timer has expired.
