Abstract
A method for inserting a PDU LI in an RLC is disclosed. According to the preferred embodiment, if a current PDU size corresponds to the total size of components of the PDU and the current PDU has information indicating that the current PDU size corresponds to the total size of components of the PDU, a component of the next PDU does not include information indicating that the current PDU size corresponds to the total size of components of the PDU. Therefore, the next PDU is free from unnecessary insertion of the LI value so that waste of network resources can be prevented and overhead required for processing unnecessary LI values also can be reduced.
Claims15
A method of forming data units to a transmitted to be receiving side, the method being used in a radio link control layer of a communication device, comprising:
- including a plurality of data units of an upper layer into a plurality of protocol data units of a lower layer;
- providing a header for a current data unit of the lower layer;
- and
- providing at least one length indicator for the header of the current data unit of the lower layer,
- wherein a second length indicator indicating that a last segment of a data unit of the upper layer ends at an end of a previous data unit of the lower layer is not included in the current data unit of the lower layer when the previous data unit of the lower layer is exactly filled with the last segment of the data unit of the upper layer and the previous data unit of the lower layer has a first length indicator indicating an end of the last segment of the data unit of the upper layer.
A method of forming data units to be transmitted to a receiving side, the method being used in a radio link control layer of a communication device, comprising:
- providing a first length indicator indicating an end of a last segment of a data unit of an upper layer for a first data unit of a lower layer including at least one data unit of the upper layer;
- and
- providing at least one length indicator for a second data unit of the lower layer including at least one data unit of the upper layer,
- wherein a second length indicator indicating that a last segment of a data unit of the upper layer ends at an end of a first data unit of the lower layer is not included in the second data unit of the lower layer when the first data unit of the lower layer is exactly filled with the last segment of the data unit of the upper layer.
A method of forming protocol data units (PDUs) to be transmitted to a receiving side, the method being used in a radio link control layer of a communication device, comprising:
- providing a first length indicator indicating an end of a last segment of a service data unit (SDU) for a first protocol data unit (PDU) including at least one SDU;
- and
- providing at least one length indicator for a second PDU including at least one SDU,
- wherein a second length indicator indicating that a last segment of an SDU ends at an end of a first PDU is not included in the second PDU when the first PDU has a third length indicator indicating that the first PDU has padding, wherein the padding has a length of zero.
