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 a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.

This patch pre-allocates one UE object that is then used
during the PRACH.

Andre Puschmann a8acd235f6 extend eNB MAC to support multiple CC per UE
- add tx/rx softbuffers for each CC that a UE might have
- make sure to call assign correct buffers when iterating
  over the CC for UL/DL grant assignment

Andre Puschmann 2edecea33e fix SIB transmission for CA
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.

Also avoid MAC calling RLC for each SIB and call RRC directly.
