Radio Link Control (RLC): To each logical channel there is one RLC instance. The RLC belongs to a single radio
bearer (RB) which represents the transmission resource for a layer 3 application (codec, RRC protocol, PDP context). The
RLC protocol offers reliability in form of sequence numbering and backward error correction. Typically one RLC belongs to
one logical channel, but for acknowledged mode one RLC instance can also utilize two logical channels.
