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.

SRBs are used by control plane.

What is time based discarding at pdcp layer and why it is used. That is quite a bit of overhead. I wonder if sspec signals are aliasing into the fake.

Fourth-generation mobile communication is the fourth generation of wireless mobile communications standards. Accordingly, LastSucceededSN is set to Pdcp phy mme sgw s1 mac inter cell rrm radio admission control rlc eutran epc. Hi Srini ,Thanks for your great work!

Download lte and the evolution to 4g wireless or read online here in pdf or epub. Ltee RLC layer of the second layer L2 supports reliable data transmission.

PDCP is user plane protocol.

Packet Data Convergence Protocol (PDCP)

One subframe includes two consecutive slots, each of which has a length of 0. I thought remote peer waits on the packet sequence number endlessly. It gives an impression that packets are stored in the PDCP layer for inorder delivery to the upper layers. I was thinking for some time that how does remote PDCP layer know about this drop.

As such, various modifications, changes, equivalents and replacements are part of the inventive features described throughout this description.

What are we supposed to do? I would say PDCP is a kind of interface between inside world and outside world. ROHC is mandatory for voice traffic.

In another embodiment, the control unit determines whether or not the difference between the sequence number assigned to the next PDCP SDU and the sequence number assigned to the last PDCP PDU completely and successfully transmitted from the lower layer is less than the predetermined number.

It is expected that this function is called by control plane after it instructs re-establishment RLC. Only practice would give you the quick answer. The method for transmitting PDCP packet, pdc the steps of: Hi Vineet, Discard packet timeout is normally configurable.

If somebody finds any inconsistency or if i had made any epec, please drop a comment or send an email. Typically, the timeout is chosen to accomodate the amount of time systems takes to do handover spex detection of new cell to end of handover process. The communication network is widely spex to provide a variety of communication services such as voice and packet data. Integrity protection and verification for control plane data: DRBs are used for sending voice and data.

However, this layer can be pretty busy stack if you enables various additional features like Integrity, Ciphering and Header Compression. In addition to the integrity protection function, the security handling unit also has a ciphering function that maintains data security, and such ciphering function applies to both U-plane data and C-plane data. Method and apparatus for performing handover using packet data convergence protocol pdcp reordering in mobile communication sppec.


In acknowledged mode, it is assumed that the directios is ‘Both’ always.

Call box mode in call box mode the drts is capable of simulating an lte network to test the signaling procedures in the mobile under test. While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

In one embodiment, the method further includes if sequence numbers are assigned to the predetermined number of or more PDCP SDUs, returning to the determining step. Method and apparatus for performing handover using packet data convergence protocol pdcp reordering in mobile communication system.

3GPP TS (1 of 5) – E-UTRA PDCP

One subframe includes a plurality of resource blocks, each of which includes a plurality of symbols and a plurality of subcarriers. MAC-I is the special lfe for Integrity protection. Method and terminal for performing handover in mobile communications system of point-to-multipoint service. Because the step of FIG.

Parameters for this function at high level are: The only differences between these two data type is the size of SN Sequence Number. So, I thought section 5.
