When the SNR value is INF, the conversion to (int) causes
-2147483648 to be displayed in the UE console.
This commit fixes the formatting, so that the values INF or
NaN would be displayed as N/A
NOTE: The issue of getting an INF value for the reported SNR metric
still needs to be addressed separately.
this issue has a tiny affect when adding new SDUs from different logical channels
to an UL MAC PDU.
Since the MAC subPDU header is accounted for twice, less SDU payload may be packed.
The patch calculates the required header space and accounts for it in the scheduling.
Howerver, it is only substracted from the available space when an SDU was actually added.
Move emergency handlers header file into the support folder.
Refactored signal handling:
- Remove the dependency with the running static variable in the header file.
- Move implementations down to cc files.
- Allow specifying a new signal handler that will be used to stop the applications.
- Move signal handling files to support.
Add channel simulator to nr_phy tests.
UL and DL channel simulators added, with AWGN and CFO using the HST scenario. The DL AWGN is adjusted according to signal power.
for the moment we always use the LTE stack (also for NSA mode).
For SA we likely pick a smarter approach to pick the stack type, i.e.
using the ARFCN specified in the config.
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.
This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.
