Pdcp header size

SpletThe common size of a TCP segment in bulk transfer over a medium speed link is 512 bytes. When a TCP segment is tunneled, the size of an IPv4, IPv6, or TCP header is 100 bytes. Thus, IPv6 and TCP headers account for 19.5% of the whole size, and IPv4 and TCP headers account for 11.7%. After PDCP header compression, however, SpletPacket Data Convergence Protocol (PDCP) In the LTE radio protocol stack, the PDCP layer is located above the RLC layer and below the IP layer (in the user plane) or the RRC layer (in the control plane). 3GPP provides a PDCP specification in [1]. From UMTS, the main function of the PDCP layer has been the header compression of IP packets ...

Spletof PDCP PDU are defined in LTE: PDCP Data PDUs and PDCP Control PDUs. PDCP Data PDUs are used for both control and user plane data. PDCP Control PDUs are only used to transport the feedback information for header compression, and for PDCP status reports which are used in case of handover (see Section 4.2.6) and hence are only used within … Splet4G5G的PDCP的对比类似于他们关于RLC层的对比，就是‘almost same’。.
