Francisco a3cb21d378 move undelivered_pdcp_sdus class methods to .cc file. Fixed the forwarding of pending PDCP SNs during S1 handover 2021-03-02 11:25:38 +01:00
Francisco 17fa79f24c couple the pdcp discard timers and sdu buffer management into same subclass. Add asserts to ensure there is no ambiguity in the PDCP SN assignment and buffering. Extend the discard timer and pdcp sdu buffering to SN lengths above 12 2021-03-02 11:25:38 +01:00
Pedro Alvarez 4723dd0aa9 Converted undelivered sdus queue in the PDCP to use a vector.
This was done to improve the performance of the notify_delivery().

Andre Puschmann 9c4146442a mac,phy: refactor NR MAC/PHY UL data passing interface
inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU

* Fix bug in early exit of notify_delivery and notify_failure

* fix compilation issue in rlc-pdcp notification

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.
