The oldest PID (the PID that was used the longest TTI ago) is at the head and is the next one that will be used. No test is done to check that when a process is allocated it is at least N TTIs old, but some quick thinking strongly leads to the 'conclusion' that N won't be smaller than 8, which seems to be what cat3 UEs require to function properly in the downlink direction (from the eNodeB to the UE).

The OpenAirInterface (OAI) software is composed of six different parts: openair1: 3GPP LTE Rel-8 PHY layer + PHY RF simulation openair2: 3GPP LTE Rel-9 RLC/MAC/PDCP/RRC implementations, eNB application, X2AP. Note that for RLC, the following versions are userL UM_v9.3.0, TM_v9.3.0, and AM_v9.3.0. For PDCP, PDCP_v10.1.0 is used. For RRC, only LITE is used. openair3: 3GPP LTE Rel9 and 10 MME/NAS, S+P-GW, HSS, S1AP (ENB and MME). common: some common OAI utilities, other tools can be found at openair2/UTILS targets: scripts to compile and lauch different system targets (simulation, emulation and real-time platforms, user-space tools for these platforms (tbd)) see README files in these subdirectories for more information see also https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/WebHome
