Rlc sublayer.PDCP sublayers are also provided to upper layer and are sequentially submitted and repeated packets detection function.In control plane, PDCP sublayers are logical
It crosses control plane PDCP packets (Control plane PDCP Data PDU) and provides Signaling Transport service for upper layer RRC, and realize
The encryption of RRC signaling and consistency protection, and the decryption and consistency check of RRC signaling are realized in the reverse direction.In addition,
PDCP layers also have user plane PDCP control packets (PDCP Control PDU), and user plane PDCP control packets have two classes at present, a kind of
It is state report (it is PDCP state reports to have two groups, one kind, and one kind is LWA state reports), one is robustness packet header pressures
Contract (ROHC, Robust Header Compression) independent feedback packet.For control plane PDCP packets and user face data PDCP
Packet, is all numbered (by PDCP sequence numbers (SN, Serial Number)), in order that the sequence and repetition wrapped are examined
It surveys, the length of SN can be 5,7,12,15,16 or 18 bits at present, can be configured by network side.For user plane
PDCP control packets, are not numbered.
PDCP state reports are used to feed back the reception condition of PDCP data PDU to sender, and sender is according to state report
Carry out the discarding or repeating transmission of data.LWA state reports are similar.
In LTE system, header-compressed is carried out using ROHC.During network transmission and wireless communication, it can use
Many transport protocols, such as transmission control protocol/Internet Protocol (TCP/IP, Transmission Control
Protocol/Internet Protocol), User Datagram Protocol (UDP, User Datagram Protocol), in real time pass
Defeated agreement (RTP, Real-time Transport Protocol) etc..The heading of these agreements has certain rule, and
And greatly in transmission process be it is constant, when single transmission data also in short-term than heading, header is just at tiring out
It is superfluous.Header can be compressed using the changing rule of header, improve efficiency of transmission.ROHC is exactly so a kind of agreement.Have
Two kinds of output packet, one is compressed packet packet, each compressed package is to pass through header-compressed by corresponding PDCP SDU
It generates, another is, is ROHC feedback packets (PDCP Control PDU for the incoherent independent packets of PDCP SDU
Interspersed ROHC feedback packet), it is one kind of user plane control PDCP packets.Compressed package always with accordingly
PDCP SDU use identical PDCP SN and COUNT values, feedback packet there is no PDCP SN, also do not encrypt.Feedback packet is decompression
Direction compression side sends feedback information, and the operating mode of terminal and the conversion of state are determined according to feedback information.ROHC is used
Compression algorithm there are mainly two types of, one is least significant bit (LSB, Least Significant Bit) Coding Compression Algorithm,
LSB compression algorithms are to carry out compressed encoding to being continuously grouped the little domain of intermediate value change.Another is that have based on window is minimum
Position (W-LSB, Window Least Significant Bit) Coding Compression Algorithm is imitated, principle is essentially identical with LSB, only W-
LSB compresses more thorough, by adjusting the size of window, only passes several different with the last time, reaches higher efficiency.
In order to meet the following higher that can be predicted, faster, newer communication requirement, industry set about expansion to not
