Andre Puschmann	5313fb99d6	tft: add helper to delete all TFTs for EPS bearer ... when a EPS bearer is removed, all associated TFTs need to be removed as well.	3 years ago
Andre Puschmann	483a216bd5	ue,stack: refactor handling of radio bearears in UE stack ... this is a rather large commit that is hard to split because it touches quite a few components. It's a preparation patch for adding NR split bearers in the next step. We realized that managing RLC and PDCP bearers for both NR and LTE in the same entity doesn't work. This is because we use the LCID as a key for all accesses. With NR dual connectivity however we can have the same LCID active at the same time for both LTE and NR carriers. The patch solves that by creating a dedicated NR instance for RLC/PDCP in the stack. But then the question arises for UL traffic on, e.g. LCID 4 what PDCP instance the GW should use for pushing SDUs. It doesnt' know that. And in fact it doesn't need to. It just needs to know EPS bearer IDs. So the next change was to remove the knowledge of what LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs. The handling and mapping between EPS bearer IDs and LCIDs for LTE or NR (mainly PDCP for pushing data) is done in the Stack because it has access to both. The NAS also has a EPS bearer map but only knows about default and dedicated bearers. It doesn't know on which logical channels they are transmitted.	3 years ago

Andre Puschmann	aaffdeb326	rrc,rlc: add method to signal protocol failure to RRC ... general-purpose method for lower layers to signal protocol failures to higher layers, i.e. RRC. In the current case, implement a direct release of the UE (enb) or a reestablishment (UE).	3 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	3 years ago
Andre Puschmann	018c734b09	dl_harq: fix unlocking of unlocked mutex bug detected by TSAN ... in the mac_test the tb_decoded() method was called twice for the 2nd codeword, causig TSAN to complain about an unlocked mutex being unlocked. The patch resolves the potential issue only calling tb_decoded for a grant/tb thas has a non-zero MCS. The patch also adjusts the reset function to have a safe and "unsafe" version to be called from inside the class, similar to other classes where we do the same.	3 years ago
