   RLC is always configured in Mobile Station (UE) and in RNC (In NW).

   Hi,

   For UM mode and other mode configuration you can refer to RLC Specification. You can get the specification here:

   http://www.3gpp.org/ftp/Specs/latest/Rel-7/25_series/25322-7a0.zip

   Refer to section 4.2.1.2 Unacknowledged mode (UM) RLC entities

   This section describes the general configuration of UM Entity.

   As RLC is configured by RRC (in Layer 3). You can use the RRC specification to know the detail configuration.

   Here is the link to RRC Specification: http://www.3gpp.org/ftp/Specs/latest/Rel-7/25_series/25331-7i0.zip

   In RRC Specification check the section for RRC Connection Setup, Radio Bearer Setup, Radio Bearer Reconfiguration.

   You can also use 3GPP specification 34.108. This describes Common test environments for User Equipment (UE);

   You can get the specification here: http://www.3gpp.org/ftp/Specs/archive/34_series/34.108/34108-710.zip

    @surender reddy

    E (Extension Bit)

    E bit tells ”What there in the next field”

    If E = 0 : Next field is data or status PDU or a complete SDUIf E 0 1 : Next filed is Length Indicator (LI) followed by extension bit (E).

    @surender reddy Hi, You download the above SW and decode one PDU. You will get detail explanation of each bits of teh RLC header both for AM and UM. FOr example decode this PDU in the decoder program:

    80010BFE01020304050000000000000000000000

    Hi,

    I am developing a tool for that but it will take some time as I am overloaded with other things right now.
