Francisco Paisana 74ffe393c6 asn1 update: s1ap asn1 is now v16.1 (2020-03) 2020-12-22 16:28:24 +01:00
Francisco Paisana 66aa34d173 update RRC NR ASN1 to 2020-09 v15.11 2020-12-18 12:50:37 +01:00
Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

Andre Puschmann bc4c9606ce rlc_am: add extended bearer metrics 
this patch adds support for measuring the:
* SDU rx latency (Average time in ms from first RLC segment to full SDU)
* amount of buffered bytes (sum of payload of PDUs buffered in rx_window)

the implementation is using std::chrono

Ismael Gomez f9a02299f9 Use MAC PDU pointer instead of tti_rx and rnti as a key to associate buffers. Decouple crc_info() and push_pdu() functions. This allows for different timing architectures in the PHY 2020-12-16 13:49:29 +01:00

Andre Puschmann c0883291f6 rlc: pass TTI to get_metrics to calculate "real" LTE rx/tx rate 
when retrieving the RLC metrics, the number of TTIs since the last
call are passed. This allows to calculate the actual rate
based on the LTE timing rather than only the system timing.

Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib
