Claim of US Patent No. 9,986,487

1. A method of operating a wireless communication network to notify a donor base station of the use of Inter-Cell Interference Coordination (ICIC) between a wireless relay and a neighboring base station, the method comprising:the donor base station exchanging first user data with the wireless relay using a first communication throughput;
a relay control system exchanging data with the wireless relay over the donor base station and the neighboring base station;
the relay control system detecting ICIC between the wireless relay and the neighboring base station and in response, identifying the donor base station serving the wireless relay and signaling the donor base station of the ICIC between the wireless relay and the neighboring base station; and
the donor base station receiving the signaling and responsively reducing the first communication throughput of the wireless relay; and
the donor base station exchanging second data with the wireless relay using the reduced communication throughput.
