2016-08-22Add decoding of compressed bitmap in EPDANpravin9-18/+774
Implemented tree based algorithm to decode compressed bitmap in EPDAN as described in section 9.1.10 of 3GPP 44.060. This algorithm intends to improve the performance over existing method. New Regression test is added under bitcomp directory. Test case is added to validate decompressed result of the bitmap Present in EPDAN. Test is done for multiple bitmaps of varying length. Invalid inputs are also part of the test vector. Change-Id: Ieae1992ed4b02bb1e09eec2d3de1a030eabd16ce

2016-08-11jenkins.sh: change build matrix to $with_dsp and $with_vtyNeels Hofmeyr1-19/+43
The new $with_dsp matrix parameter is defined as "sysmo" or empty/"none". The lc15 DSP might be added in the future. Fetch the sysmo layer 1 API only if with_dsp==sysmo. The new $with_vty parameter is independent of $with_dsp, it is now up to jenkins to define a matrix filter. For compat, until jenkins is reconfigured with the new matrix parameters, use $sysmodsp to init the new parameters to reflect previous behavior. The $sysmobts matrix parameter made no sense, drop it.

2016-08-02Add support for SPB handling for EGPRS UL TBFAravind Sirsikar6-25/+908
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 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.

The rationale behind this from GP-091955: "Due to that P-channels are not deployed by any operator and are not expected ever to be, it has decided to remove the requirement on mandatory support of P-channels for the mobile stations in A/Gb mode."

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.

2016-07-13Add test cases to support ARQ-II for EGPRS DL RetxAravind Sirsikar3-0/+644
During MCS upgradation such as MCS6->MCS9, 2 blocks which were sent separately as MCS6, will be clubbed into one MCS9 block during retransmission. Same holds good for MCS5->MCS7 transistion. During MCS reduction such as MCS9->MCS6,2 blocks which were sent together will be sent separately during the retransmission case. Same is verified through the generated log file. Currently MCS8->MCS6 transition is not supported. The retransmission MCS is being calculated from Table of TS 44.060. The same test cases are also integration tested on Nuran 1.0 platform.
