Earlier there was an incorrect encoding of PUAN when VQ is not equal VR case for EGPRS UL RLC window. The PCU was encoding the same PUAN message always irrespective of radio condition. This was a bottle neck for performance testing. Which has been fixed in this patch. Related: OS#1793 unit test assertion in the previous commit is fixed in this patch.

Modify the EGPRS DL TBF flow to support Split block during Retx. This patch will also Upgrade the test suite with test cases to validate the EGPRS Downlink SPB for Retransmission Scenarios like MCS6->MCS3, MCS4->MCS1, MCS5->MCS2, MCS9->MCS3 MCS7->MCS2, MCS8->MCS3 have been simulated and Integration tested in NuRAN 1.0 hardware thoroughly. Change-Id: I242afdd8ae7622dec8593b26382ad66bad5b9516
2016-08-25Add data structure to handle SPB for EGPRS DLAravind Sirsikar2-4/+45
Modify the header files with necessary data structure to handle Split block for EGPRS DL TBF. The EGPRS resegmentation feature allows PCU to retransmit RLC blocks of HeaderType1, HeaderType2 by segmenting them to 2 HeaderType3 blocks(Example MCS5 will be retransmitted as 2 MCS2 blocks). Table 10.4.8b.2 of 44.060 explains the possible values of SPB in HeadrType3 for DL direction. The PCU decides to retransmit the blocks by resegmenting it based on Table 8.1.1.1 of 44.060. The retransmission MCS is calculated based on current MCS of the Block and demanded MCS by PCU. Section 10.3a.3.3 of 44.060 shows the HeadrType3 with SPB field present in it Change-Id: I57673e53a9da2affa7e8aaa6551ac4b271c3d525

2016-08-02Add support for SPB handling for EGPRS UL TBFAravind Sirsikar3-24/+161
This patch will modify the EGPRS UL TBF flow to support Split block handling. This patch also contains test suite modification for SPB UL. Scenarios like MCS6->MCS3, MCS4->MCS1, MCS5->MCS2, MCS9->MCS3 MCS7->MCS2, MCS8->MCS3 have been simulated and Integration tested in NuRAN 1.0 hardware thoroughly. The scope of Unit testing is limited.

2016-08-02Add data structure for SPB in EGPRS ULAravind Sirsikar1-0/+40
Modify header files with data structures required to support split blocks for EGPRS UL TBF This feature provides provision for MS to retransmit RLC blocks of HeaderType1, HeaderType2 by segmenting them to 2 HeaderType3 blocks(Example MCS5 will be retransmitted as 2 MCS2 blocks). Table 10.4.8b.1 of 44.060 explains the possible values of SPB in HeadrType3 for UL direction. When the MCS is changed at the PCU, PCU directs the changed MCS to MS by PUAN or UPLINK ASSIGNMENT message along with RESEGMENT flag, Then MS may decide to retransmit the blocks by resegmenting it based on Table 8.1.1.1 of 44.060. The retransmission MCS is calculated based on current MCS of the Block and demanded MCS by PCU. Section 10.3a.4.3 of 44.060 shows the HeadrType3 with SPB field present in it.

2016-07-28Properly set TA_VALID bitMax1-3/+6
Check Timing Advance validity and set corresponding bit for Immediate Assignment message. Previously !polling was errorneously used (polling bit has nothing to do with TA validity according to 3GPP TS 44.018 Table 10.5.2.16.1) which lead to TA being always valid as polling is always 0 in other parts of the code.

2016-07-14egprs: Use RLC/MAC headers from libosmocoreTom Tsou3-125/+31
EGPRS Type 1, 2, and 3 headers are used by OsmoPCU and OsmoBTS. Move the header definitions to libosmocore to be shared by both packages. Modify the struct variable naming to use *_hi/*_lo instead of *_a/*_b in order to be consistent with existing naming used in libosmocore. Change-Id: I98687ad981d27502aec42729611937ba1caf207c
2016-07-13bitvector: Remove code clone and fallback to C implementationHolger Hans Peter Freyther2-18/+7
This routine has been moved from from here to libosmocore and as part of the C++ -> C the reference got converted to a pointer. We have a lot of code that calls the method with the reference and instead of updating the callers, create a short inline wrapper to call the C routine.
