The presence of a limited number of predefined beams at RU poses constraints to the scheduler at gNB. As a matter of fact, the scheduler can serve only a limited number of beams, depending on the RU characteristics (possibly only 1), in a given time scale, that also depends on the RU characteristics (e.g. 1 slot or 1 symbol). This limitation doesn't exist for digital beamforming.
Analog beamforming implementation also allows to enable distributed antenna systems (DAS), where each beam corrisponds to one antenna (or a set of antennas) of the system. In this scenario, the scheduler constaint is alleviated because normally the number of concurrent beams allowed equals the total number of beams.
# Configuration file fields for analog beamforming
A set of parameters in configuration files controls the implementation of analog beamforming and instructs the scheduler on how to behave in such scenarios. Since most notably this technique in 5G is employed in FR2, the configuration file example currently available is a RFsim one for band 261.

- `set_analog_beamforming` can be set to 1 or 0 to activate or desactivate analog beamforming (default value is 0)
- `beam_duration` is the number of slots (currently minimum duration of a beam) the scheduler is tied to a beam (default value is 1)
- `beams_per_period` is the number of concurrent beams the RU can handle in the beam duration (default value is 1)
- `beam_weights` is a vector field containing the set of beam indices to be provided by the OAI L1 to the RU is also required. In current implementation, the number of beam indices should be equal to the number of SSBs transmitted
In the `gNBs` section of the configuration file, under the phyisical parameters, a vector field containing the set of beam indices to be provided by the OAI L1 to the RU is also required. This field is called `beam_weights`. In current implementation, the number of beam indices should be equal to the number of SSBs transmitted.
DAS is enabled by setting to 1 the parameter `enable_das` in the L1 section of the configuration file. In case of DAS enabled, the field `beam_weights` in `MACRLC` section can be omitted.
# Implementation in OAI scheduler

To this goal, we extended the virtual resource block (VRB) map by one dimension to also contain information per allocated beam. As said, the scheduler can independently schedule users in a number of beams up to `beams_per_period` concurrently.
It is important to note that in current implementation, there are several periodical channels, e.g. PRACH or PUCCH for CSI et cetera, that have the precendence in being assigned a beam, that is because the scheduling is automatic, set in RRC configuration, and not up to the scheduler. For these instances, we assume the beam is available (if not there are assertions to stop the process). For data channels, the currently implemented PF scheduler is used. The only modification is that a UE can be served only if there is a free beam available or the one of the beams already in use correspond to that UE beam.
# FAPI implementation
To be noted that in our implementation analog beamforming is only supported in non-split/monolithic mode because we don't support yet SCF P19 interface that would be needed to manage these procedure in a split scenario with SCF FAPI.
In `config_request` structure, a vendor extension (`nfapi_nr_analog_beamforming_ve_t`) configures the lower layers at initialization with the following information:
- `analog_bf_vendor_ext` which can assume values 1 or 0 for enabling or disabling analog beamforming
- `num_beams_period_vendor_ext` which corresponds to the configuration parameter `beams_per_period`
- `total_num_beams_vendor_ext` which corresponds to the number of beams configured in `beam_weights`
- `analog_beam_list` which contains the RU beamforming indices configured in `beam_weights`
Additionally, L2 provides in each channel FAPI message information about the beam index. Small Cell Forum (SCF) FAPI provides in its PHY API specifications for the channels only a field for digital beamforming as part of the `precoding_and_beamforming` stucture. Therefore without a better option, we are currently using that one to store the internal analog beamforming index. This is the index used internally by the code to progressively identify the beam with a value from 0 to `total_num_beams_vendor_ext`.
# L1 implementation
To handle multiple concurrent beams, the buffers containing Tx and Rx data in frequency domain (`txdataF` and `rxdataF`) have been extended by one dimension to contain multiple concurrent beams to be transmitted/received.
The function `beam_index_allocation`, called by every L1 channel, is responsible to match the FAPI analog beam index to the RU beam index and to store the latter `beam_id` structure, which allocates the beams per symbol, despite L2 only supporting beam change at slot level. At the same time, the function returns the concurrent beam index, to be used to store data in frequency domain buffers. While doing so, the function also checks if there is room for current beam in the list of concurrent beams, which should always be the case, if L2 properly allocated the channels.
In case of DAS, since each beam corresponds to a specific antenna port, the `beam_index_allocation` function is simplified in the sense that the beam index corresponds to the antenna port index of the frequency domain buffers.
# RU implementation
The implementation is still work in progress.
The first dimension of the Tx and Rx buffers that used to contain the number of Tx/Rx antennas, it is now extended to contain the number of parallel streams which is the number of antennas multiplied by the number of concurrent beams.
