Pedro Alvarez dd6d6f731d Passing SN provided by upper layers to PDCP entity. Using it to calculate TX_COUNT if passed. 4 years ago
Pedro Alvarez fcaaf72187 Starting to add discard functionality to PDCP LTE entity. 
This includes:
  - Adding a queue (implemented with std::map) for undelivered PDUs.
    This queue uses the SN used for TX as the key.
  - Added discard timer that is started upon reception of the SDU. Upon
    expiry of the timeout a discard callback removes undelivered PDUs
from the queue.
  - Added the mechanisms to the notify_delivery to remove PDUs from the
    undelivered queue when the PDU is ACK'ed.
  - Added test case for both timer expiry and acknowledgment.
  - Fix up the getter for buffered SDUs to return the undelivered SDUs
  - Changed default PDCP discard timer, so AM has a discard timer by
    default.

Xavier Arteaga a19671802e Added SRSUE NR-PUSCH initial procedures 4 years ago
Pedro Alvarez de90b4753f Added the ability of the RLC AM to notify the PDCP of the acknowledged 
PDCP PDUs. This includes:

- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
  the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
  amount of ack'ed bytes and the total size of the PDCP PDU,
  so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
  notify the PDCP when it receives an ack from the status PDUs. The RLC
  passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
  where the PDUs are acked imediatly, and one test where the PDU is
  retx'ed.

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object 
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160
