How DL data transfer algorithm works for DRBs mapped to RLC AM in PDCP ? (36.323 5.1.2.1.2)

DL data transfers in PDCP when DRB mapped on RLC AM mode.

36.323. (Section :- 5.1.2.1.2)

This section mentioned alogithm but I want to know how conditions are defined ?
eg.
- if received PDCP SN – Last_Submitted_PDCP_RX_SN > Reordering_Window or 0 <= Last_Submitted_PDCP_RX_SN – received PDCP SN < Reordering_Window: ------> This is actually seems to be condition when PDU is out of reorder window boundary.

  • Is this due ti circular definitions for PDCP SN ?

  • kindly suggest any document which will give some detail description about it.

Thanks .

In specification of RRC and PDCP i.e 36.331 and 36.323, PDCP SN is defined with variable length such as 7 bits, 12 bits, 15 bits and 18 bits. I want to know in which scenario upper layer (RRC/application) decides on using the different length for PDCP SN ?
