Abstract
In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.
Claims10
A method for transmitting, by a transmitting device, a data unit, the method comprising:
- generating a first protocol data unit (PDU) and a second PDU,
- wherein the first PDU contains a first sequence of service data unit (SDU) elements, the first sequence of SDU elements including zero or one SDU segments followed by zero or more complete SDUs followed by a first SDU segment, each SDU element of the first sequence being associated with a respective consecutive sequence number,
- wherein the second PDU contains a second sequence of SDU elements, the second sequence of SDU elements starting with a second SDU segment followed by zero or more complete SDUs followed by zero or one SDU segments, each SDU element of the second sequence being associated with a respective consecutive sequence number,
- wherein a sequence number of the second SDU segment in the second PDU is the same as a sequence number of the first SDU segment in the first PDU,
- transmitting the first PDU;
- and
- transmitting the second PDU,
- wherein each SDU element of the first and second PDUs are associated with an indicator indicating whether that SDU element is a complete SDU or is a SDU segment.
A transmitting device for transmitting a data unit, the transmitting comprising:
- at least one processor, and
- at least one memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
- generating a first protocol data unit (PDU) and a second PDU,
- wherein the first PDU contains a first sequence of service data unit (SDU) elements, the first sequence of SDU elements including zero or one SDU segments followed by zero or more complete SDUs followed by a first SDU segment, each SDU element of the first sequence being associated with a respective consecutive sequence number,
- wherein the second PDU contains a second sequence of SDU elements, the second sequence of SDU elements starting with a second SDU segment followed by zero or more complete SDUs followed by zero or one SDU segments, each SDU element of the second sequence being associated with a respective consecutive sequence number,
- wherein a sequence number of the second SDU segment in the second PDU is the same as a sequence number of the first SDU segment in the first PDU,
- transmitting the first PDU;
- and
- transmitting the second PDU,
- wherein each SDU element of the first and second PDUs are associated with an indicator indicating whether that SDU element is a complete SDU or is a SDU segment.
