Patent ID: 8897216

Claim:
A method for transmitting a packet at a radio link control (RLC) layer, the method comprising: generating an acknowledge mode data (AMD) protocol data unit (PDU) from at least one RLC service data unit (SDU), the AMD PDU being within a current maximum PDU size; storing the AMD PDU in a retransmission buffer; transmitting the AMD PDU; and segmenting and retransmitting the AMD PDU as a plurality of AMD PDU segments in response to a status report that indicates a negative acknowledgement (NACK) signifying an unsuccessful transmission of the AMD PDU and the AMD PDU size is greater than a maximum AMD PDU size allowed for retransmission of the AMD PDU, wherein the plurality of AMD PDU segments include additional header information, wherein header information of the original RLC PDU is included in at least in one of the segmented RLC PDUs and a segmentation field indicating the segmented RLC PDUs is included in the additional header information and the header further comprises a field to indicate a version of RLC SDU segmentation.
