Francisco Paisana 567790c1a2 Renamed struct to store cell context in rrc. Moved sib buffers to this struct. Created helper methods for lookup 2020-03-13 11:46:12 +00:00
Francisco Paisana 349aed5e0d use sib configuration to set SCellToAddModList 2020-03-13 11:46:12 +00:00
Andre Puschmann b7aad27d86 move packing of SCell list into extra method and add fill PHY config on the spot 
previously we've packed the RRCReconfig with SCellToAddMod list and have then
parsed the message again to pack the PHY config dedicated for the new SCell carrier. This
is now done in one step.

Pedro Alvarez 96c82b3fc6 Moved PDCP configs to pdcp_config.h. Added `as_security_cfg_t` structure to hold access stratum keys. 
Refactored PDCP, RRC and USIM accordingly.

Andre Puschmann f2e1bfa699 refactor naming for s/p/cell structs and {enb,ue}_cc_idx 2020-03-10 15:01:00 +01:00
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.

Andre Puschmann 120ad76c63 refactor cell param handling and fix SIB transmissions 
- move cell specific eNB params to cell list in rr.conf
- make sure DL EARFCN and DL freq can be used to manually overwrite a single cell config
- fix SIB packing and transmission for multi cell configs
- introduce cell list to MAC
- adapt default enb.conf.example and rr.conf.example
