Embodiment Construction
[0025] The utility function associated with the femtocell is:
[0026] (1)
[0027] in for the Femtocell users on channels letter-to-dry ratio, femtocell transmit power, is the interference value received by home user i from other home base stations, is a non-negative weight coefficient, is additive white Gaussian noise. The SINR of femtocell users is:
[0028] (2)
[0029] In the above formula for the first Femtocell user and the first The path loss between femtocells, is the transmit power of the macro base station, for the first The path loss between a home user and the macro base station. Considering the interference limitation of macro users, a third item can be added on the basis of this utility function, which is related to the interference of macro users. Because there is no interference between each subchannel, so as long as the user's performance on each subchannel is discussed, the problem of the present inv...
