Increased BW, COTS UE not connecting.

[stavrosdim]

Hi,

Has anyone tried to connect their COTS UEs to srsran gNB with a BW above 20 MHz? The UE detects the SSB, but it doesn’t attempt to attach. I have tried with Google Pixel 5 and OP 8 5G mmWave. Here is the gNB configuration file I am using:

cu_cp:
amf:
addr: 127.0.0.5
bind_addr: 127.0.0.1
supported_tracking_areas:
- tac: 1
plmn_list:
- plmn: "00101"
tai_slice_support_list:
- sst: 1

ru_sdr:
device_driver: uhd # The RF driver name.
device_args: type=x300, num_recv_frames=64,num_send_frames=64
clock: external # Specify the clock source used by the RF.
sync: external # Specify the sync source used by the RF.
tx_gain: 31 # Transmit gain of the RF might need to adjusted to the given situation.
rx_gain: 28

cell_cfg:
dl_arfcn: 536020
band: 7
channel_bandwidth_MHz: 30
common_scs: 15
plmn: "00101"
tac: 1

If you’ve seen this before or have any suggestions, I’d really appreciate the help.
