Abstract:
1. A method for radio link control (RLC) re-segmentation, the method comprising: generating an original RLC protocol data unit (PDU) from at least one RLC service data unit (SDU), an RLC PDU size being within a minimum and maximum RLC PDU size; storing the original RLC PDU in a retransmission buffer; transmitting the original RLC PDU; if transmission of the original RLC PDU fails and the original RLC PDU size is larger than an updated maximum RLC PDU size at the time of retransmission of the original RLC PDU, segmenting the original RLC PDU to segmented RLC PDUs; storing the segmented RLC PDUs in the retransmission buffer; and transmitting the segmented RLC PDUs.
