Wireless telecommunications network

A method of configuring a wireless telecommunications network, the method being performed by a data processing apparatus, the wireless telecommunications network including a first wireless transmitter, the method comprising:

• obtaining data indicating an amount of data transmitted by the first wireless transmitter in each Modulation and Coding Scheme (MCS) of a plurality of MCSs;
• estimating a change in received signal strength for the first wireless transmitter when using a first candidate configuration relative to a current configuration;
• estimating a first spectral efficiency for the first candidate configuration based on the amount of data transmitted by the first wireless transmitter in each MCS of the plurality of MCSs and the received signal strength change for the first wireless transmitter when using the first candidate configuration;
• comparing the estimated first spectral efficiency for the first candidate configuration to a reference spectral efficiency;
• and
• causing a reconfiguration of the wireless telecommunications network based on the comparing.
