Merge branch 'develop' of https://gitlab.eurecom.fr/oai/openairinterface5g into maki

When antenna 0 is muted but other antennas are active, SSB data
(generated only on port 0) is now copied to remaining active antennas.
This ensures UE can still detect cell with partial antenna muting.

Behavior:
- TX mask 0x03: Full 2x2 MIMO
- TX mask 0x02: TX1 only, SSB copied from TX0
- TX mask 0x01: TX0 only, normal SSB
- TX mask 0x00: All muted, UE loses sync (correct)

-# We use YAML anchors to ease the configuration and to avoid duplicating parts of the configuration.
-# This is especially true for the SNSSAIs, as we have to define them for multiple NFs.
-# Please note that the use of anchors is not mandatory, and you can define the SNSSAI in each NF yourself.

+O-RU and O-DU are connected via the Fronthaul (FH) interface.
+FH traffic is logically diviced into 4 planes:
+1. Control Plane which transports real-time slot configuration control messages
+2. User Plane which transports IQ samples data (amplitude and phase)
+3. Synchronization Plane transports timing information messages
+4. Management Plane carries non-real-time management operation messages
+
+C/U Plane messages are exchanged using the eCPRI protocol.
+
+The energy consumption of RU can be modeled as
+P = P_0 + P_RF + P_BB + P_PAM
+where
+P_0   : baseline components in the RU (fabric, ethernet, PCIe, etc.)
+P_RF  : a-to-d/d-to-a converters (ADC/DAC) and the freq up/down converters
+P_BB  : core digital processor (eFPGA) and the other low-PHY processing units
+        (e.g. beamforming) for each antenna chain
+P_PAM : power amplifier module (PAM) at each antenna chain
+
+The paper claims that components other than PAM are rather static (?)
+-> I guess the PAM is controlled by RF. Thus P_RF is the minimum amount of power
+   required to run RF.
+
+P_PAM = P_(PAM, 0) * P_(PAM, c)(r) * E_PAM * n_ant
+where
+P_(PAM, 0) : baseline power consumption that depends on the n of antennas,
+             ganging elements, and the maximum EIRP per antenna
+             * EIRP (Effective Isotropic Radiated Power) is the total power radiated
+             by an antenna in the direction of its maximum gain, referenced to an ideal isotropic radiator.
+P_(PAM, c)(r) : a factor that depends on _the amount of subcarriers to be amplified_,
+                which in turn depends on the n of RBs (r) carried therein
+E_PAM         : captures the efficiency of the amplifier to convert DC power into signal power gain
+n_ant         : n of radio chains (with ONE amplifier per radio chain)
+
+> This observation motivates the principle behind the solution we propose in this paper:
+  consolidate data into as few symbol periods as possible, using more radio resources per period instead.
+Since keeping PAM awake consumes more energy, it is better to send data in short bursts, where each burst
+utilizes more spectrum resources

+## O-RAN Compliance
+
+This implementation follows O-RAN Alliance specifications:
+
+| O-RAN Element | Implementation |
+|---------------|----------------|
+| WG4 `o-ran-uplane-conf.yang` | `tx-array-antenna-mask-config`, `rx-array-antenna-mask-config` |
+| `antenna-bitmask` parameter | `nr_antenna_state_t.tx_antenna_bitmask` |
+| `MPLANE-TRX-CONTROL` feature | `mplane_set_tx_antenna_mask()`, `mplane_set_rx_antenna_mask()` |
+| NETCONF edit-config/validate/commit | `radio/fhi_72/mplane/antenna-control-mplane.c` |
+| Transmission blanking | Zeroing `txdataF_BF` for muted antennas |

+
+## Usage
+
+### Production Mode: O-RAN M-Plane NETCONF
+
+For O-RAN compliant deployments, use the NETCONF interface:
+
+```c
+#include "radio/fhi_72/mplane/antenna-control-mplane.h"
+#include "radio/fhi_72/mplane/ru-mplane-api.h"
+
+// After establishing M-Plane connection to RU...
+extern ru_session_t *ru_session;  // From M-Plane init
+
+// Check if RU supports antenna control
+if (mplane_supports_trx_control(ru_session)) {
+    // Set TX antenna mask (0x0F = all 4 antennas active)
+    antenna_ctrl_result_t result = mplane_set_tx_antenna_mask(
+        ru_session,
+        "tx-array-0",  // Array name from RU capabilities
+        0x0F,          // Bitmask: bit N=1 means antenna N active
+        4              // Number of antennas
+    );
+    
+    if (result != ANTENNA_CTRL_SUCCESS) {
+        LOG_E(PHY, "Failed to set TX mask: %s\n", antenna_ctrl_result_str(result));
+    }
+}
+```
+
+#### Integrated with PHY Layer
+
+```c
+#include "PHY/NR_TRANSPORT/nr_antenna_state.h"
+#include "PHY/NR_TRANSPORT/nr_antenna_control.h"
+
+// Initialize antenna state
+nr_init_antenna_state(&gNB->antenna_state, 4, 4, "tx-array-0", "rx-array-0");
+
+// Connect to M-Plane backend
+nr_antenna_control_init_mplane(&gNB->antenna_state, ru_session);
+
+// Changes via nr_set_tx_antenna_bitmask() will be synchronized to RU
+nr_set_tx_antenna_bitmask(&gNB->antenna_state, 0x03);  // Enable only antennas 0,1
+nr_antenna_control_sync_to_ru(&gNB->antenna_state);    // Push to RU via NETCONF
+```
+
+### Development Mode: Test Socket Interface
+
+For testing without NETCONF infrastructure:
+
+```c
+#include "PHY/NR_TRANSPORT/nr_antenna_state.h"
+#include "PHY/NR_TRANSPORT/nr_antenna_control.h"
+
+// Initialize with 4 TX and 4 RX antennas
+nr_init_antenna_state(&gNB->antenna_state, 4, 4, "tx-array-0", "rx-array-0");
+
+// Start test socket server (NOT O-RAN compliant - logs warning)
+nr_antenna_control_start_test_server(&gNB->antenna_state, 9999);
+```
+
+**Warning**: The test socket interface is for development only and is NOT O-RAN compliant.
+
+### Control Antennas via Test Interface
+
+Connect with netcat:
+```bash
+nc localhost 9999
+```
+
+Commands:
+```
+> HELP                    # Show all commands
+> STATUS                  # Show current antenna state
+> MUTE TX 2              # Mute TX antenna 2
+> MUTE TX 3              # Mute TX antenna 3
+> SET TX MASK 03         # Set TX mask to 0x03 (antennas 0,1 active)
+> SYNC                   # Sync to RU (M-Plane backend only)
+> STATS                  # Show energy saving statistics
+```
+
+### Use in Beamforming
+
+```c
+// Original (all antennas active):
+nr_beam_precoding(txdataF, txdataF_BF, fp, beam_weights, slot, symbol, aa, nb_ap, offset);
+
+// With antenna muting support:
+nr_beam_precoding_with_muting(txdataF, txdataF_BF, fp, beam_weights, 
+                               slot, symbol, aa, nb_ap, offset,
+                               &gNB->antenna_state);
+```
+
+## Building with M-Plane Support
+
+To build with O-RAN M-Plane NETCONF support:
+
+```bash
+cd openairinterface5g/cmake_targets
+./build_oai --ninja --gNB --nrUE -w ORAN_FH -t MPLANE
+
+# Or manually:
+cmake .. -DENABLE_ORAN_FH=ON -DORAN_FH_VARIANT=MPLANE
+make -j$(nproc)
+```
+
+Dependencies for M-Plane:
+- libnetconf2 >= 2.1.25
+- libyang >= 2.1.4
+- libssh
+
+## Testing with rfsimulator
+
+### Prerequisites
+
+1. Build OAI:
+```bash
+cd openairinterface5g/cmake_targets
+./build_oai --ninja --gNB --nrUE -w SIMU
+```
+
+2. Install Open5GS:
+```bash
+sudo add-apt-repository ppa:open5gs/latest
+sudo apt update
+sudo apt install open5gs
+```
+
+3. Add subscriber to Open5GS (using mongosh):
+```bash
+mongosh open5gs --eval 'db.subscribers.insertOne({
+  imsi: "999700000000001",
+  security: { k: "fec86ba6eb707ed08905757b1bb44b8f", amf: "8000", opc: "C42449363BBAD02B66D16BC975D77CC1" },
+  slice: [{ sst: 1, default_indicator: true, session: [{ name: "internet", type: 3 }] }]
+})'
+```
+
+### Quick Test (Antenna Control Only)
+
+The easiest way to verify the implementation is to start the gNB and test the control interface:
+
+```bash
+# Terminal 1: Start gNB
+cd cmake_targets/ran_build/build
+sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.pci0.rfsim.conf --rfsim
+
+# Terminal 2: Test antenna control
+echo "STATUS" | nc -w 2 localhost 9999
+echo "MUTE TX 0" | nc -w 2 localhost 9999
+echo "STATUS" | nc -w 2 localhost 9999
+echo "STATS" | nc -w 2 localhost 9999
+```
+
+### Full Test with Open5GS
+
+Terminal 1 - Core Network (should already be running):
+```bash
+# Verify Open5GS is running
+systemctl status open5gs-amfd open5gs-upfd open5gs-smfd
+```
+
+Terminal 2 - gNB (with Open5GS-compatible config):
+```bash
+cd cmake_targets/ran_build/build
+sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.2x2.rfsim.open5gs.conf --rfsim
+```
+
+Terminal 3 - UE:
+```bash
+cd cmake_targets/ran_build/build
+sudo ./nr-uesoftmodem -r 106 --numerology 1 --band 78 -C 3319680000 \
+    --rfsim -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/ue.open5gs.conf
+```
+
+Terminal 4 - Antenna Control:
+```bash
+nc localhost 9999
+> STATUS
+> MUTE TX 1    # Mute antenna 1
+> STATUS
+> STATS
+```
+
+Terminal 5 - iperf (after UE attaches):
+```bash
+# Server on the UPF
+iperf3 -s -B 10.45.0.1
+
+# Client from UE (or use tun interface)
+ping 10.45.0.1
+iperf3 -c 10.45.0.1 -t 30
+```
+
+### Using the Test Script
+
+A convenience script is provided:
+```bash
+./targets/PROJECTS/GENERIC-NR-5GC/CONF/run_antenna_muting_test.sh gnb    # Start gNB only
+./targets/PROJECTS/GENERIC-NR-5GC/CONF/run_antenna_muting_test.sh mute   # Test muting
+./targets/PROJECTS/GENERIC-NR-5GC/CONF/run_antenna_muting_test.sh status # Check status
+./targets/PROJECTS/GENERIC-NR-5GC/CONF/run_antenna_muting_test.sh --help # Show all options
+```
+
+### Observing MIMO Layer Reduction
+
+With 4x4 MIMO:
+- All antennas active: Up to 4 layers possible
+- 2 antennas muted: Max 2 layers
+- 3 antennas muted: Max 1 layer
+
+Throughput should decrease proportionally as antennas are muted.
+
+## API Reference
+
+### O-RAN M-Plane NETCONF API
+
+```c
+// Set TX antenna mask via NETCONF
+antenna_ctrl_result_t mplane_set_tx_antenna_mask(
+    ru_session_t *ru_session,    // Active NETCONF session
+    const char *array_name,      // O-RAN TX array name
+    uint8_t antenna_bitmask,     // Bitmask (bit N=1 -> antenna N active)
+    uint8_t num_antennas         // Number of antennas in array
+);
+
+// Set RX antenna mask via NETCONF
+antenna_ctrl_result_t mplane_set_rx_antenna_mask(
+    ru_session_t *ru_session,
+    const char *array_name,
+    uint8_t antenna_bitmask,
+    uint8_t num_antennas
+);
+
+// Check if RU supports MPLANE-TRX-CONTROL feature
+bool mplane_supports_trx_control(ru_session_t *ru_session);
+
+// Result codes
+typedef enum {
+    ANTENNA_CTRL_SUCCESS = 0,
+    ANTENNA_CTRL_ERR_NO_SESSION,
+    ANTENNA_CTRL_ERR_FEATURE_NOT_SUPPORTED,
+    ANTENNA_CTRL_ERR_INVALID_ARRAY_NAME,
+    ANTENNA_CTRL_ERR_INVALID_MASK,
+    ANTENNA_CTRL_ERR_NETCONF_FAILED,
+    ANTENNA_CTRL_ERR_VALIDATION_FAILED,
+    ANTENNA_CTRL_ERR_COMMIT_FAILED
+} antenna_ctrl_result_t;
+```
+
+### Unified Control Interface
+
+```c
+// Initialize with O-RAN M-Plane NETCONF backend (production)
+bool nr_antenna_control_init_mplane(nr_antenna_state_t *ant_state, void *ru_session);
+
+// Start test socket server (development - NOT O-RAN compliant)
+bool nr_antenna_control_start_test_server(nr_antenna_state_t *ant_state, int port);
+
+// Sync local state to RU (M-Plane backend only)
+bool nr_antenna_control_sync_to_ru(nr_antenna_state_t *ant_state);
+
+// Get current backend type
+nr_antenna_ctrl_backend_t nr_antenna_control_get_backend(void);
+```
+
+## Future Work
+
+1. ~~**O1 NETCONF Integration**: Integrate with `radio/fhi_72/mplane/` for production O-RAN compliance~~ ✅ **DONE**
+2. **NETCONF Notifications**: Subscribe to `mplane-trx-control-ant-mask-update` notifications
+3. **rApp Development**: Create Non-RT RIC rApp for policy-based antenna control
+4. **A1 Policy Interface**: Enable policy-based control from SMO
+5. **Power Measurement**: Add actual power consumption metrics (requires hardware)

+ * \author OpenAirInterface
+ * \date 2025
+ * \version 2.0
+ * 
+ * This module provides antenna control for MIMO muting / energy saving.
+ * 
+ * Two modes of operation are supported:
+ * 
+ * 1. O-RAN M-PLANE NETCONF (Production/O-RAN Compliant):
+ *    When linked with the M-Plane library (radio/fhi_72/mplane/), uses
+ *    real NETCONF sessions to control antenna masks via O-RAN YANG models:
+ *    - o-ran-uplane-conf.yang tx-array-antenna-mask-config
+ *    - o-ran-uplane-conf.yang rx-array-antenna-mask-config
+ *    - Requires MPLANE-TRX-CONTROL feature support on RU
+ * 
+ * 2. Test Socket Interface (Development/Testing):
+ *    A simple TCP socket interface for testing without NETCONF infrastructure.
+ *    NOT O-RAN compliant, but useful for development and simulation.
+ *    Enable with nr_antenna_control_start_test_server().
+ * 
+ * For O-RAN compliant deployments, use the M-Plane interface directly
+ * via radio/fhi_72/mplane/antenna-control-mplane.h
