Patent ID: 10375602

Abstract:
A data packet has a header and a radio link control (RLC) protocol data unit (PDU). The RLC PDU transports at least one full RLC service data unit (SDU), one or two RLC SDU fragments, or at least one full RLC SDU and at least one RLC SDU fragment. An RLC SDU fragment is only located (i) at the beginning or end of the RLC PDU or at the end of the radio link control protocol data or (ii) at the beginning and end of the RLC PDU. A single field in the header consists of a first bit and a second bit, even when a number of full RLC SDUs and RLC SDU fragments in the RLC PDU is more than two. The single field indicates whether (i) the RLC PDU begins with a fragment of a RLC SDU and (ii) the RLC PDU ends with a RLC SDU fragment. The data packet is formed including the configured header and the configured RLC PDU and transmitted.
