Also, if a technical term herein is not specifically defined in a different manner, such will be interpreted to have the meaning that one of ordinary skill in the art would understand, without an excessively broad or excessively narrow interpretation. The PDCP layer is terminated in the eNB 20 and may perform functions such as header compression, integrity protection, s;ec ciphering.

Method for reordering a packet data convergence protocol packet data unit at a user equipment in a dual connectivity system and device therefor. Reduced latency, higher user data rates, improved system capacity and coverage.

This interface function is expected to be called by control plane when it requires reestablishment of PDCP ltee. I will not go into those details here as the specification is very clear on them. In acknowledged mode, it is assumed that the directios is ‘Both’ always.

System and method for multi-point hsdpa communication utilizing a multi-link pdcp sublayer.

Accordingly, data loss occurs. PDCP layer is also informed of reestablishment by the control plane.

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. On reciever side, we can figure out many things like “Is the data getting delivered in order?

If there are any pending DL packets, they get retransmitted with new cipher context. The mobile terminal or network entity may include the spe of FIGS. The header compression function allows efficient transmission of Internet protocol IP packet, such as an IPv4 or IPv6 packet through a radio interface that has a relatively narrow bandwidth.

Effective reception method in wireless communication system providing Spfc service.

PDCP – Wikipedia

The mobile terminal or network entity may include the protocols of FIGS. Namely, the function of the header compressor is applied only for the U-plane data, and the integrity protection function among the functions of the security handling unit is applied only for the C-plane data.

Wireless communication method for transmitting a sequence of data units between a wireless device and a network. Fields that are to be sent along with the status report is described in section 5. Next generation mobile network the evolution lts 4g technology to quickly solve problems in. The present invention relates to mobile communication, and more particularly, to a PDCP packet transmission method.

Random technical bits and thoughts: LTE PDCP from eNodeB perspective

Hereafter, with reference to the attached drawings, some embodiments will be explained, and regardless of the reference numbers in the drawings, some elements may be labeled with the same reference numbers and any repetitive explanations may have been omitted merely for the sake of brevity.

Parameters for this function at high level are: Pdcp sae bearer control ciphering and integrity protection of nas signaling. The method of the present invention may be implemented in a mobile terminal or network entity.


Second-generation mobile communication refers to the transmission and reception of voice in a digital form, such as CDMA, GSM, and the likes. Ciphering process can also be disabled by applying EEA0. The left side depicts the transmitting side having a buffera header compressora security handling unitand a PDCP header attachment unitwhile the right side depicts the receiving side having a PDCP header removal unita security handling unita header decompressorand a buffer Method and apparatus for transmitting and receiving data using a plurality of carriers in mobile communication system.

My perception of any process is “a black box that convert a set of inputs into a set of output”. The features shown in the attached drawings are merely depicted to improve the understanding of the present invention and should not be interpreted to limit the teachings of the present invention. The main services and functions of the pdcp sublayer for the user plane include.

According to the present invention, when the Discard Timer is not set to infinity, if no radio link failure occurs, and the low signal environment continues, it is possible to prevent the discarding of or more PDCP SDUs with pdfp numbers already assigned thereto wpec limiting the maximum number of transmission data.
