Description
This ticket should document what needs to be done in terms of supporting VAMOS from OsmoBTS, and to track its status via check-lists and possibly sub-issues.
Our implementation will be focusing on osmo-bts-trx as none of the "proprietary PHY" we support implement any VAMOS support.
- Indication of [which level of] VAMOS support the BTS has via OML attributes to BSC
- Implementation of "shadow TRX" concept in data structures
- Implementation of VAMOS related RSL extensions on Abis
- Implementation of a new TRXDv2 protocol from/to the TRX
- VAMOS-aware uplink + downlink power control
- generation of one set of downlink symbols from the real + shadow timeslot/lchan
The corresponding BSC related work is tracked in #4940
