Update MCS selection for retransmission In 3GPP TS 44.060 the selection of MCS for retransmissions is defined as separate tables (8.1.1.1 and 8.1.1.2) depending on the value of resegmentation bit (which is opposite to the way EGPRS_ARQ are defined in the source code). Let's follow the same idea and explicitly check for resegmentation bit value and use separate tables. This also makes it easier to add proper support for special cases (MCS-6-9 and MCS-5-7) and padding in future independently for different ARQ types. The code is also moved to c to avoid unnecessary conversions to and from cpp class. Change-Id: Ia73baeefee7a58834f0fc50e3b8bf8d5e3eb7815
This repository contains a C/C++-language implementation of a GPRS Packet Control Unit, as specified by ETSI/3GPP. It is part of the Osmocom Open Source Mobile Communications project.
The Packet Control Unit is terminating the Layer 2 (RLC/MAC) of the GPRS radio interface and adapting it to the Gb Interface (BSSGP+NS Protocol) towards the SGSN.
The PCU interfaces with the physical layer of the radio interface. OsmoPCU is typically used co-located with the BTS, specifically OsmoBTS. For legacy BTSs that run proprietary sotware without an interface to OsmoPCU, you may also co-locate it with the BSC, specifically OsmoBSC
The official homepage of the project is https://osmocom.org/projects/osmopcu/wiki/OsmoPCU
You can clone from the official osmo-pcu.git repository using
git clone git://git.osmocom.org/osmo-pcu.git
There is a cgit interface at http://git.osmocom.org/osmo-pcu/
We provide a user manual as well as a vty reference manual
Please note that a lot of the PCU configuration actually happens inside the BSC, which passes this configuration via A-bis OML to the BTS, which then in turn passes it via the PCU socket into OsmoPCU.
