The way it's used now (upgrade to multislot for DL TBF upon LLC frame arrival) doesn't seem right because DL and UL TBF do not exist at that moment. Nevertheless, encoding routine is complete for EGPRS (no GPRS yet) and trigger functions and state changes provide nice illustration into internal workings of the scheduler. Hence we'll keep it here for the time being. Signed-off-by: Max <msuraev@sysmocom.de> |

This is an implementation of Packet Control Unit (PCU) according to TS 04.60 The PCU is part of BSS, so it connects directly to SGSN. == Current limitations == * No PFC support * No fixed allocation support * No extended dynamic allocation support * No unacknowledged mode operation * No PCCCH/PBCCH support * Only single slot assignment on uplink direction * No half-duplex class support (only semi-duplex) * No handover support * No measurement support * No TA loop * No power loop * No CS loop * No EGPRS
