There are two main functionality is performed by PDCP layer. one is header compression/decompression and second security. header compression is just use to reduce IP packet size so that packet can be sent using less readio resource because best radio resource uses is primarily objective of lte.

If header-compression field is NULL, then PDCP will not peform header compression/decompression for that bearer. It means all the GTP packets coming from SGW to eNB over that bearer. PDCP layer will remove GTP header from all the packets then it will get plain IP packets and without header compression it will submit packets to lower layer RLC layer.

Thanks that was my thought too that it will not do the compression in this case.

Can someone provide me some details that how this conversion is possible by which it compresses the IP header (Minimum of 20 bytes) in to Token that is 1 to 4 bytes ?

I found 1st bit which is used to indicate that packet carrying Data/Control information. My question is that why first bit is used even packet itself known as "PDCP Data PDU".

I am bit confused here. I have just started to reading this and had a look at header and found that In header part there is no length field. the protocols i am bit aware GTP, Diameter they have length field present.
