Cedric Roux b55b63c5ab hotfix: hack to improve PHICH generation 
The eNodeB may sometimes wrongly generate PHICH because somewhere
'phich_active' is not reset to 0, due to an unidentified reason. When
adding this hack the problem seems to disappear completely.

This is not the end of the story. The real underlying problem has to be
understood and fixed correctly.

Cedric Roux 6bb69e1964 hotfix: correct Msg3 ressource blocks reservation 
The Msg3 ressource blocks used by random access procedure
were not correctly handled. The MAC scheduler could wrongly
allocate a ressource block for both random access Msg3 and
a regular UE.

This hotfix hopefully fixes the problem.

A new function "set_msg3_subframe" has been added in the
interface between PHY and MAC.

Cedric Roux c03f13c07b T: add a trace for PHICH 2016-11-18 10:29:48 +01:00
Cedric Roux 64615dcc8e hotfix: correct PHICH generation 
The PHICH generation is wrong.
HARQ process X is uplink scheduled at TTI n.
At TTI n+4 the eNB receives the data.
At TTI n+8 the eNB sends ACK/NACK on the PHICH.

The problem is that PHICH generation is done after scheduling.
And PHICH generation uses "first_rb" and "n_DMRS" to compute
"ngroup_PHICH" and "nseq_PHICH".

So at TTI n+8 if the eNB has reused the HARQ process X for
a new uplink scheduling the values "first_rb" and "n_DMRS"
may have changed.

We need to use the previous values.

One solution would have been to do PHICH generation before
scheduling. The problem is that "generate_phich_top" does more
than PHICH generation. It has to setup parameters to sort of
"emulate" a DCI0 in case of retransmission scheduled without
DCI0. So part of it has to be done after scheduling. We would
have to split the function.

The simple adopted fix is to store old values of "first_rb"
and "n_DMRS" and use those values in "generate_phich_top".

This fix has only been tested with FDD. TDD may miserably fail.

Cedric Roux f116a10de3 hotfix: turbo decoder should not fail if CRC is 0 
The case of a CRC == 0 is legal.

After discussion with Raymond, it is also possible to have all
bits at 0 (and so a CRC==0) if there is no transmission and thus
not much energy.

So this hotfix may introduce new problems (false decoding).

A future work is to handle this case properly by not calling the
turbo decoder if there is not enough energy received.

The problem might manifest itself more in the UE part, especially
when it tries to decode MIB and/or SIB (if I understood correctly).

Cedric Roux 190fc96af4 issue 137 - fix RI bits decoding 
RI bits are present only in some transmission modes.

For aperiodic reporting (the mode we do as of today),
36.213 7.2.1 (release 10) says:

    "RI is only reported for transmission modes 3 and 4,
    as well as transmission modes 8 and 9 with PMI/RI reporting"

This commit activates decoding of RI bits only for transmission
modes 3 and 4. 8 and 9 are not done today (as far as I know).

Cedric Roux b0887a1b85 issue 137 - correct computation of G 
G was wrongly computed in some places, not taking into account
CQI and RI bits. This commit saves the correct value computed
in ulsch_decoding so we can reuse it in ulsch_decoding_data
(and the like).

Only the file openair1/PHY/LTE_TRANSPORT/ulsch_decoding.c has
been checked. If the computation is done somewhere else the
problem might still exist.

Most of them were the GPL.

It is useless to have a copy of the license in every
sub-directory.

From now on, there is only the LICENSE in the top
