Pilot signals for use in multi-sector cells

A wireless terminal, the wireless terminal including:

• receiver means for receiving pilot signals;
• measuring means for measuring at least one of an amplitude or a phase of a first pilot signal to produce a first measured signal value and at least one of an amplitude or a phase of a second pilot signal to produce a second measured signal value;
• channel quality indicator value generation means for generating a first channel quality indicator value from the first measured signal value according to a first function which uses at least the first measured signal value as an input and generates a second channel quality indicator value from the second measured signal value according to a second function which uses at least the second measured signal value as an input, wherein the channel quality indicator value generation means includes the second channel quality indicator value in the first message;
• and
• transmitter means for transmitting the first and second channel quality indicator values.

A device comprising a processor configured to control the device to implement a channel quality reporting method, the method comprising:

• measuring at least one of an amplitude or a phase of a first pilot signal corresponding to a first pilot tone to produce a first measured signal value;
• generating a first channel quality indicator value from the first measured signal value according to a first function which uses at least the first measured signal value as an input;
• transmitting the first channel quality indicator value, wherein transmitting the first channel quality indicator value includes:
• incorporating the first channel quality indicator value into a first message;
• and
• transmitting the first message over a wireless communications link;
• measuring at least one of an amplitude or a phase of a second pilot signal corresponding to a second pilot tone to produce a second measured signal value, the second pilot signal having a different transmission power than that of the first pilot signal;
• generating a second channel quality indicator value from the second measured signal value according to a second function which uses at least the second measured signal value as an input;
