Step enb setup10/31/2023 ![]() ![]() The PCI of each cell with the same EARFCN must be different, such that PCI%3 for the cells is not equal. Note, the TAC of the cells must match that of the MME, and the EARFCN must be the same across both cells and the UE. The following shows an example of the cell added to the existing rr.conf: The rr.conf is where the cells (sectors) are added to the eNB, this is also where the handover flags are enabled. ![]() The second most significant unit is used to indicate which cell the port belongs to. By having the least significant unit of each Rx port be 0 and Tx port be 1 the flowgraphīecomes easier to debug. The use of a clear labelling system for the ports is employed to allow for easier implementation of the GRC broker. The following table should make clear how the TCP ports are allocated across the cells: Cell Ports Used ¶ #dl_earfcn = 3350 tx_gain = 80 rx_gain = 40 # Example for ZMQ-based operation with TCP transport for I/Q samples device_name = zmq device_args = fail_on_disconnect = true, id = enb, tx_port0 = tcp : //* : 2101, tx_port1 = tcp : //* : 2201, rx_port0 = tcp : // localhost : 2100, rx_port1 = tcp : // localhost : 2200, id = enb, base_srate = 23.04e6 #
