LTE;. Evolved Universal Terrestrial Radio Access (E-UTRA);. Packet Data Convergence Protocol (PDCP) specification. (3GPP TS version Release. PDCP is an abbreviation for Packet Data Convergence Protocol. This protocol is specified by 3GPP in TS for UMTS, TS for LTE and TS for 5G New Radio [NR). The PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G Air 3GPP TS Packet Data Convergence Protocol (PDCP ) specification. Packet Data Convergence Protocol (PDCP) specification. (Release 8). The present document has been developed within the 3rd Generation Partnership Project.

So, lye is required to have terminate bearer function for all bearers belonging to UE. Also, any words or phrases used herein in the singular may be interpreted to cover their plurality, unless clearly described to the contrary. Determination of acceptable sequence number ranges in a communications protocol.

The present invention relates to mobile communication, and more particularly, to a PDCP packet transmission method. Also, any words or phrases used herein in the singular may be interpreted to cover their plurality, unless clearly described to the contrary. Similarly, uplink packets which are received out-of-order also sent to the dpec eNB. Note that in LTE, both voice and data use packet switching. Method for processing a packet data convergence protocol service data unit at a user equipment in a dual connectivity system and device therefor.

The method of claim 1wherein the method is performed by a PDCP entity. The only differences between these two data type is the size of SN Sequence Number.

Packet Data Convergence Protocol (PDCP)

Next generation mobile network the evolution to 4g technology to quickly solve problems spex. The packets in Re Transmit queue either get discarded either when they get acknowledged or when the timer fires on it. First Let’s briefly look at the data zpec. As illustrated in FIG. In one embodiment, the method further includes: For example, without exceeding the scope of the present invention, a first element can also be explained as a second element, while a second element can also be explained as a first element.

The size equals toi. Ofcourse, there is initialization, configuration, monitoring etc. Data is transferred between the MAC layer and the physical layer via the transport channel.

If ciphering is properly performed, no data loss occurs. The first diagram is as follows.

Pdxp the PDCP layer gets this indication from the control plane, it should start forwarding the un-acknowledged downlink packets and uplink packets that are received out-of-order. PDCP specification says that Section 5. Below is a logical digram of eutran protocol layers with a depiction of data flow through various layers.

Since many processors support security engine, there are no core cycles required to do actual ciphering and integrity-checks. Data is also transferred via a physical channel between a physical layer of a transmission side and a physical layer of a reception side.

This function is called when the PDCP layer is informed of handover for a given context. Integrity Information is not valid for DRB packets. Last packet is expected to be indicated explicitly.

Accordingly, data loss occurs. The NAS control protocol may use three different states. Lte enb pdcp rlc rlc nr rlc mac pdcp gnb nr pdcp nr rlc nr mac s1 s1 mcg bearer split bearer scg bearer xx mcg master cell group scg secondary cell group.

Can anyone give the estimate? However, if the channel status is not good, a state of not receiving sufficient grants from an eNB may continue, and this may cause the discarding of a large amount of PDCP SDUs from the transmitting side when the Discard Timer is activated. The present invention relates to mobile communication, and more particularly, to a PDCP packet transmission method. Method for reordering a packet data convergence protocol packet data unit at a user equipment in a dual connectivity system and device therefor.
