Abstract
A transmitting apparatus (10, 20) includes a control unit (12, 22) configured to generate PDCP (Packet Data Convergence Protocol) data containing information indicating at least a part of a HFN (Hyper Frame Number) held in the transmitting apparatus, and a transmitting unit (11, 21) configured to transmit the PDCP data generated by the control unit to a receiving apparatus.
Claims8
A transmitting method wherein a computer:
- generates PDCP (Packet Data Convergence Protocol) data containing information indicating at least a part of a HFN (Hyper Frame Number) value held in the computer;
- and
- transmits the generated PDCP data to a receiving apparatus,
- wherein the computer generates PDCP data containing four or more lower-order bits of the HFN value held in the computer in at least the third to the sixth bits in a PDU (Protocol Data Unit) in which a PDCP SN (Sequence Number) value is expressed by 18-bits.
1 more element
A receiving method wherein a computer:
- receives PDCP (Packet Data Convergence Protocol) data containing information indicating at least a part of a HFN (Hyper Frame Number) value held in a transmitting apparatus;
- and
- updates the HFN value held in the computer based on the information indicating at least a part of the HFN value contained in the received PDCP data,
- wherein the computer receives PDCP data containing four or more lower-order bits of the HFN value held in the transmitting apparatus in at least the third to the sixth bits in a PDU (Protocol Data Unit) in which a PDCP SN (Sequence Number) value is expressed by 18-bits.
1 more element
A transmitting apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- generate PDCP (Packet Data Convergence Protocol) data containing information indicating at least a part of a HFN (Hyper Frame Number) value held in the transmitting apparatus;
- and
- transmit the generated PDCP data to a receiving apparatus,
- wherein the at least one processor generates PDCP data containing four or more lower-order bits of the HFN value held in the transmitting apparatus in at least the third to the sixth bits in a PDU (Protocol Data Unit) in which a PDCP SN (Sequence Number) value is expressed by 18-bits.
