Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target RAN by initiating a fake handover of a user equipment (UE) from the source RAN cell to the target RAN
Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target RAN by initiating a fake handover of a user equipment (UE) from a source RAN cell to a target RAN.

The handover request will fail, because the handover request is not for any actual UE moving from the source RAN cell to the target RAN. However, the target RAN becomes aware of the source RAN cell as a result of this process and can add the source RAN cell (e.g., its EARFCN) to a list of its neighboring cells.

Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target ran by initiating a fake handover of a user equipment (UE) from the source RAN cell to the target RAN
Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target RAN by initiating a fake handover of a user equipment (UE) from a source RAN cell to a target RAN.

If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.
H04B 1/48 - Transmit/receive switching in circuits for connecting transmitter and receiver to a common transmission path, e.g. by energy of transmitter
H04L 5/14 - Two-way operation using the same type of signal, i.e. duplex
