the filter alpha was initialized to zero by default which causes an
issue because the first measurement for a cell can't be updated,
because the filtering function will always return the current value.
According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.
- fix srsenb reestablishment check for UE context. The pci has to be accounted for the srsenb to understand that the UE trying to do reestablishment corresponds to one of its own
this rather large patch changes the way cells are handled in the SS.
It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.
It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.
before epoll can handle signals, the calling thread needs to block
them. the blocking needs to happen before any other threads get
spawned so they inherit the mask.
* remove single line MAC PDU subheader logging in favor
of to_string() helper that prints entire MAC header in single line
* log MAC PDU after parsing and packing
the Tx SDU has been set to 128 PDUs because this gives approx.
150kByte UL buffer state (max value for Rel 8 BSR).
Previously, however, we've always reported too much pending UL
data because we weren't subtracting the transmitted data from
the reported data.
with this newer BSR reporting, however, even with full buffers we would
never report full buffers because the queues size is too short.
This seems to cause issues for iperf TCP sessions not resulting
in full DL rate, see isse #1703. It seems that the TCP bandwitdh
probing works better with larger buffers (in our case this can
only be achieved with more PDUs in the pool).
This should fix#1703
when removing a user from the eNB we iterated over all possible LCIDs
and set the buffer state to zero in the scheduler.
this resulted in following log entries:
13:57:23.856334 [RRC ] [I] Received Release Complete rnti=0x46

we now check if the bearer exits at RLC and only report those to the MAC.
