Francisco Paisana c46402c836 fix phy configuration during handover on srsenb. The function srsenb::rrc::ue::fill_scell_to_addmod_list assumes that the phy_cfg of the PCell is up-to-date, which was not the case. With this PR, the srsenb rrc updates the phy_cfg before the ho cmd is sent, but, in the case of intra-enb ho, the updates are not submitted to the phy before the reception of the crnti mac ce 2020-10-07 09:10:47 +01:00

Francisco Paisana 2e10c8e13d bug fix - eNB was not allocating UL grants for an UE that has performed intra-enb handover. The problem resulted from the fact that the ue configuration in the scheduler not accounting for removed cells. 2020-10-03 09:12:40 +01:00

faluco f0d651ae8e - Fixed a leak in the MME class not releasing the static byte buffer pool. 
- Now the pool gets destroyed on program exit using a unique_ptr.
- Removed manual cleanup() calls in all the code base to free the pool instance.

Francisco Paisana 13a5bfb525 - fix reestablishment reject transmission in the srsenb. For SRB0 SDUs, no RLC header is required, so we do not need to check in such case if there is enough space in the TB for the header. 
- 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

Andre Puschmann 655c7ae8ae enb: fix warning when removing user 
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
13:57:23.856352 [MAC ] [W] [ 5149] The provided lcid=6 is not valid
13:57:23.856362 [MAC ] [W] [ 5149] The provided lcid=7 is not valid
13:57:23.856368 [MAC ] [W] [ 5149] The provided lcid=8 is not valid
13:57:23.856371 [MAC ] [W] [ 5149] The provided lcid=9 is not valid
13:57:23.856376 [MAC ] [W] [ 5149] The provided lcid=10 is not valid

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

Andre Puschmann 1d1d52f3e6 enb: fix stopping of input thread 
since we've used a blocking read of stdin (with std::getline())
we had a race when the eNB was stopped and the user was still making
keyboard inputs. this is because the we didn't wait until the input
thread was terminated until we stopped the eNB.

we know use poll to query stdin (getline has no timeout mechanism).
