Francisco Paisana	b3eb9651d6	disable cqi in scells during handover procedure	4 years ago
Francisco Paisana	8a9a95a937	ensure sibs are acquired if cell selection calls cell search	4 years ago
Francisco Paisana	045f647914	fix edge case where serving cell is good enough for reestablishment but the sibs are not yet acquired	4 years ago
Francisco Paisana	5ecbe8fb17	cleanup of the reestablishment procedure state machine. It does not need to wait for the serving cell configuration because such procedure is already included in the cell selection procedure	4 years ago
Pedro Alvarez	b3bfe336a9	Make sure that remote address test has a ip mask	4 years ago
Sylvain Munaut	5783c01cbb	tf_packet_filter: Improve support for the different filter types	4 years ago
Francisco Paisana	0997daa7a0	now the handover procedure in the srsUE does not wait for the phy cell selection result. It only waits for the RA result	4 years ago

Francisco Paisana	cf89d6645b	add comments explaining each function of the reest procedure	4 years ago
Francisco Paisana	d068d594af	implemented rrc reestablishment procedure part after sending reest request	4 years ago

Andre Puschmann	1afc137032	[REBASE] Make PHY non-blocking and fefactor HO procedure (#1753) ... * Make PHY non-blocking and fefactor HO procedure * makes entire PHY non-blocking through command interface * adds dedicated queue for cell_search/cell_select commands * refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs * force ue to always apply SIB2 configuration during reestablishment * Run update_measurements in all workers Co-authored-by: Ismael Gomez <ismagom@gmail.com>	4 years ago
Francisco Paisana	7f8af023b8	added a callback that always gets triggered when the phy cell selection completes. This callback checks if cell selection failed, and if so, sets the rsrp of the selected cell to -infinity	4 years ago
Andre Puschmann	b616944a13	ue,rrc: fix security config during HO/reestablishment ... we fix a number of very related issues for HO/reestablishment in the success/error case: * this patch removes the hard-coded check that intra-cell HO aren't allowed. There are cases where eNBs use this method to update the security context. * the patch also fixes an issue after failed HO where the security context of the source eNB should be used for the reestablishment. * update security keys according to specs when mobilitycontrol indicated change of key	4 years ago
Andre Puschmann	6827c2df21	rrc_meas: disable layer3 filtering until quantity config is received ... 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.	4 years ago
Ismael Gomez	f49fbd6d02	Fix the order of HO/reest measurement actions (#1696)	4 years ago
Andre Puschmann	aec18a93d1	mux,bsr: refactor UL buffer status reporting ... this patch fixes the UL BSR as per TS 36.321, it includes following main changes: * report UL buffer state to reflect the UEs transmit buffer after the MAC UL PDU containing the BSR has been built. In other words, if the UE, for example, can transmit all outstanding data in an UL grant, it will not report any pending data to transmit. * refactor MUX routines and subheader space calculation	4 years ago

Francisco Paisana	48138b5281	removal of phy cell selection procedure as it now it is replaced by phy controller	5 years ago
Francisco Paisana	489969722e	implemented phy controller FSM to perform cell selection & search. The controller also tracks the phy sync state	5 years ago
Andre Puschmann	a7911f0dab	pdcp,rlc: refactor SDU queueing policy ... this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer. the previous design had issues when packets have been generated at a higher rate above the PDCP than they could be consumed below the RLC. When the RLC SDU queues were full, we allowed two policies, one to block on the write and the other to drop the SDU. Both options are not ideal because they either lead to a blocking stack thread or to lost PDCP PDUs. To avoid this, this patch makes the following changes: * PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP * remove blocking write from pdcp and rlc write_sdu() interface * all writes into queues need to be non-blocking * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC * log warning if RLC still needs to drop SDUs * this case should be avoided with the monitoring mechanism	5 years ago
