Abstract
A transmission-side PDCP entity performs PDCP concatenation processing of concatenating a plurality of PDCP Service Data Units (SDUs) and thereby generates a PDCP PDU including a concatenated SDU. A reception-side PDCP entity performs PDCP segmentation processing of segmenting the concatenated SDU included in the PDCP PDU into the plurality of PDCP SDUs. A first communication apparatus including one PDCP entity transmits control information used for control of the PDCP concatenation processing and/or the PDCP segmentation processing to a second communication apparatus including the other PDCP entity.
Claims19
A communication method used in a mobile communication system comprising a pair of Packet Data Convergence Protocol (PDCP) entities comprising a transmission-side PDCP entity for transmitting a PDCP Protocol Data Unit (PDU) and a reception-side PDCP entity for receiving the PDCP PDU, the communication method comprising the steps of:
- performing, by a transmission-side PDCP entity, PDCP concatenation processing of concatenating a plurality of PDCP Service Data Units (SDUs) and thereby generating a PDCP PDU comprising a concatenated SDU;
- performing, by a reception-side PDCP entity, PDCP segmentation processing of segmenting the concatenated SDU comprised in the PDCP PDU into the plurality of PDCP SDUS;
- and
- transmitting control information used for control of the PDCP concatenation processing and/or the PDCP segmentation processing from a first communication apparatus comprising one of a pair of PDCP entities to a second communication apparatus comprising the other of the pair of PDCP entities,
- wherein the generating of the PDCP PDU comprises inserting a partition code between each of the plurality of PDCP SDUs constituting the concatenated SDU.
A communication apparatus used in a mobile communication system comprising a pair of Packet Data Convergence Protocol (PDCP) entities comprising a transmission-side PDCP entity for transmitting a PDCP Protocol Data Unit (PDU) and a reception-side PDCP entity for receiving the PDCP PDU, the communication apparatus comprising:
- a controller comprising one of a transmission-side PDCP entity and a reception-side PDCP entity, wherein
- the transmission-side PDCP entity is configured to perform PDCP concatenation processing of concatenating a plurality of PDCP Service Data Units (SDUs) and thereby generate a PDCP PDU comprising a concatenated SDU by inserting a partition code between each of the plurality of PDCP SDUs constituting the concatenated SDU,
- the reception-side PDCP entity is configured to perform PDCP segmentation processing of segmenting the concatenated SDU comprised in the PDCP PDU into the plurality of PDCP SDUS, and
- the controller is configured to transmit control information used for control of the PDCP concatenation processing and/or the PDCP segmentation processing to another communication apparatus.
A chipset for a communication apparatus used in a mobile communication system comprising a pair of Packet Data Convergence Protocol (PDCP) entities comprising a transmission-side PDCP entity for transmitting a PDCP Protocol Data Unit (PDU) and a reception-side PDCP entity for receiving the PDCP PDU, the chipset configured to execute processing of:
- performing, by the transmission-side PDCP entity, PDCP concatenation processing of concatenating a plurality of PDCP Service Data Units (SDUs) and thereby generate a PDCP PDU comprising a concatenated SDU by inserting a partition code between each of the plurality of PDCP SDUs constituting the concatenated SDU;
- performing, by the reception-side PDCP entity, PDCP segmentation processing of segmenting the concatenated SDU comprised in the PDCP PDU into the plurality of PDCP SDUS;
- and
- transmitting control information used for control of the PDCP concatenation processing and/or the PDCP segmentation processing to another communication apparatus.
