Method and apparatus for transmitting data packets and method and apparatus for receiving data packets
First Claim
1. A method for transmitting a data packet having a header and a radio link control protocol data unit, comprising steps of:
- configuring the radio link control protocol data unit to transport at least one full radio link control service data unit, one or two radio link control service data unit fragments, or at least one full radio link control service data unit and at least one radio link control service data unit fragment, where a radio link control service data unit fragment is only located (i) at the beginning of the radio link control protocol data unit or at the end of the radio link control protocol data unit or (ii) at the beginning of the radio link control protocol data unit and at the end of the radio link control protocol data unit;
configuring a single field in the header consisting of a first bit and a second bit, even when a number of full radio link control service data units and radio link control service data unit fragments in the radio link control protocol data unit is more than two, the single field indicating whether (i) the radio link control protocol data unit begins with a fragment of a radio link control service data unit and (ii) the radio link control protocol data unit ends with a radio link control service data unit fragment;
forming the data packet including the configured header and the configured radio link control protocol data unit; and
transmitting 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.

7. A method for receiving a data packet, comprising steps of:
-
receiving the data packet that includes a data packet header and a data packet radio link control protocol data unit, the data packet header including a single field consisting of a first bit and a second bit even when a number of full radio link control service data units and radio link control service data unit fragments in the data packet radio link control protocol data unit is more than two, the single field indicating whether (i) the data packet radio link control protocol data unit begins with a fragment of a radio link control service data unit and (ii) the data packet radio link control protocol data unit ends with a radio link control service data unit fragment; and the data packet radio link control protocol data unit including at least one full radio link control service data unit, one or two radio link control service data unit fragments, or at least one full radio link control service data unit and at least one radio link control service data unit fragment, where a radio link control service data unit fragment is only located (i) at the beginning of the data packet radio link control protocol data unit or at the end of the data packet radio link control protocol data unit or (ii) at the beginning of the data packet radio link control protocol data unit and at the end of the data packet radio link control protocol data unit; and restructuring radio link control service data unit(s) and/or radio link control service data unit fragment(s) in the received data packet based on the single field. - View Dependent Claims (8, 9)
