Francisco ceaef3523f sched,feature: Enable setting the target PHR below which the maximum UL grant size starts decreasing 4 years ago
Francisco 486823e5de sched,bugfix: The PHR handling scheme now considers the number of PRBs of the UL grant that carried the PHR. Before, it was assuming the most conservative scenario of Nprb=1 4 years ago

Francisco 84ad6dd8ee Integrated new sched_dl_cqi class in sched_ue_cell 
- extend sched_dl_cqi interface to allow getting tti when cqi was last updated
- extend sched_dl_cqi to quickly get average cqi across the whole bandwidth

Francisco 16d05ff042 Remove time exponential averaging of DL cqi 
- renaming: sched_cqi -> sched_dl_cqi
- testing: add unit test for sched_dl_cqi wideband cqi mode.
- feature: remove time exponential averaging of dl cqi

Francisco d3c51fdad4 limit minimum UL grant size to accommodate both BSR and RLC headers 4 years ago
Francisco 01eace2631 rrc paging mechanism improvements 
- moved paging record handling to separate class
- parallel access to pending pcch messages by phy workers based on TTI and without common lock
- asn1 pcch message packing now takes place in stack thread, to avoid real-time issues

Francisco f7a8b8bf94 separate drb srb ids into separate enum types 4 years ago
Francisco 21718af3b6 avoid allocating std::string to get lcid radio bearer name. Refactored the lte radio bearer enum type 4 years ago
Francisco 60d5c6df7b implementation of memory pool with individual memory blocks per UE that get accessed via their rnti 4 years ago
Pedro Alvarez 8194b5ec73 Added check for consequetive KOs in MAC. Change set_activity_user to pass activity and max KOs to RRC and trigger RLF timeout. 4 years ago
Francisco 5eccfad05b gtpu - added comments, updated expected construct, handled in rrc the case a gtpu teid fails to allocate 4 years ago

Francisco 1f35c4dc8b sched, feature enhancement, bugfix - allow RAR DL grants with variable PRB size 
Some bug fixes had to be solved:
