naoi af6ca15020 Fix: Random access information is not released when Msg3(response to PDCCH order) re-transmission fails. 2018-02-28 17:11:37 +09:00
Cedric Roux c9f89db89b hotfix: clear DCI padding bits 
The problem is the following (as reported by an user):

  "one UE is attached to OAI system. UE is near the antenna. Try to detach
  the UE and attach again. Repeat this procedure for 5-6 times. OAI system
  does not work and any the UE can not attach to this system. I use TEMS
  software and I can see MIB signaling on this UE but UE can not decode SIB1
  and SIB2."

What happens is that the DCI for SIB1 and SIB2 is not cleared before
use. That is the bits in the 'padding' field keep the values that were
set before. If the structure has been used to transmit other DCIs
(eg. for UEs) in the past, it may be reused with some of those bits set
to 1. When receiving this DCI, the UE won't accept it because it
gets some bits at 1 where it expects them to be 0.

The short-term/quick solution is to clear the 'padding' field.
A better solution would be to rewrite this part of the code,
which is way too complicated for what it does. But this takes
too much time.

In dci.h the field 'dummy' of some structures was renamed to 'padding'.
The fields 'padding32' and 'padding64' were also renamed to 'padding'
for consistency.

Some structures (DCI2B_1_5MHz_TDD, DCI2B_10MHz_FDD, DCI2D_1_5MHz_FDD,
DCI2D_5MHz_FDD, DCI2D_10MHz_FDD) had a 'padding' field at the end, which
was renamed to 'padding0'. I don't know if this field should be here at all.
To me this field looks very suspicious. When we test DCIs 2B and 2D we
should be careful.

naoi 497a3275c6 fix: drop reestablishment request after UL failure is detected in layer2. 
eNB should be keep UE context longer than T311 timer after UL failure is detected in layer2.
Configuration file(GENERIC-LTE-EPC) sets T311 to 10s, so eNB keep UE context up to 20s.
