We assumed that PRACH FFT size is equivalent to PxSCH FFT size.
However, the parameter ru_config->fftSize is used for the C-plane Section Type 3
which is dedicated for PRACH and mixed numerology.
Based on the PRACH format, short or long, the PRACH values 256 or 1024
shall be filled.

When doing analogue beamforming, the beam ID for a pre-defined beam
table is passed directly to RU and there is no need to store the beam
table in PHY.
When there is real-time issues in L1 it may happen that the scheduler misses/skips some slots, thus, L2 not processing and not freeing some structures like PUCCH.
This commit avoids the Assertion by resetting any Active outdated PUCCH

Add symbol timing functions for NR_DL_FRAME_PARMS + optimization for slot timing
counterparts
Add two new functions for calculation symbol timestamp and symbol duration for
NR_DL_FRAME_PARMS. Also includes an optimization focused on removing
inefficiencies related slot-related counterparts.
1. Removed function pointers for functions get_samples_per_slot(),
get_samples_slot_timestamp() and get_slot_from_timestamp() as it does
not offer any advantage. The functions are now called directly from
everywhere.
2. Optimized these functions by removing loops where ever possible.
Update documenation for handover
Update documentation for handover to include the changes that were made after
upgrading the CI handover setup (attenuator, USRPs synchronization)
NR UE: calculate TA based on SIB19 information in NTN mode, if autonomous TA is not enabled
To achieve the goal, the hyper frame number (HFN) is introduced at the NR UE
PHY, MAC and RRC layers.
Besides this, we also implemented an orbit propagation to improve the accuracy
of N_UE_TA_adj, and a fix to keep the N_TA from RAR and MAC CE.
Fixes#981
Add two new functions for calculation symbol timestamp and symbol
duration for NR_DL_FRAME_PARMS. These functions are not using
the existing indirection mechanism via function pointers as this
prevents the compiler from properly optimizing the code.

Fixes for BWP switching
This MR fixes some issues when performing BWP switching via
reconfiguration. It also adds a CI test for BWP switching. # Please
enter a commit message to explain why this merge is necessary,
In all cases (CFRA in SA for HO, or CFRA in NSA/do-ra for access), the
UE has the full configuration already. We can therefore directly switch
to a dedicated search space, as it is already known to the UE.
... so if we want to have 1 BWP configured at any given time we need to
reconfigure BWP 1 every time. This means that since the gNB has more
than 1 BWPs (for use for different UEs), that there is a "gNB BWP ID"
(as used by the gNB), which can be any BWP ID X, and one "UE BWP ID",
which is always 1. This commit implements this distinction.
Return from triggering reconfiguration with BWP switch if BWP is the
same as before the switch, and add check to verify if BWP triggered by
switch command exists
