Abstract: The invention relates to a data packet structure for conveying data of service data units (SDU) using protocol data units (PDU). The data packet comprise a data packet payload comprising at least one protocol data unit (PDU), wherein a protocol data unit (PDU) comprises a service data unit (SDU) or a fragment of a service data unit; and a data packet header comprising an indicator (FFF,SFF) indicating whether or not the data packet payload begins with a protocol data unit (PDU) being a fragment of a service data unit and whether or not the data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.

Abstract: A receiver receives a data packet with a header and a payload. The payload includes at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment, where a service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. The header includes a single field consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. Digital signal processing circuitry processes the header to determine processing for the payload.

Abstract: A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment. A service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. At least one digital signal processor is used to configure a single field in the header consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. At least one digital signal processor is used to form the data packet including the configured header and the configured payload. A transmitter transmits the data packet.

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.
