event

Francisco Paisana 74c18ecf6c implementation of SCell Deactivation 2020-10-12 14:45:13 +01:00
Francisco Paisana eafc003671 Altered the way the generation of the scheduling decision for a given 
TTI is made. Instead of generating one CC in each dl_sched()/ul_sched()
call, all CC decisions are generated at once. This avoids race
conditions with calls from the RRC to the MAC to configure UEs.

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
Francisco Paisana 8a5a571045 bug fix - in case of intra-enb Handover, the eNB was not adding SCells in the HO command 2020-10-02 20:10:28 +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
