can be seen that the method with maximum capacity assigns all the resource to user 1.
Static TDMA tends to allocate equal capacity to each user based on the principle that
all users have the same opportunities to transmit. However, this method does not sa-
tisfy the requirement of proportional fairness owing to the lack of a fairness control
mechanism. Meanwhile, consider the method using only sub-channel allocation. Al-
though the user rate distribution has no strict regulation, it satisfies a rough rate con-
straint and the total system capacity is close to maximum capacity. Using the pro-
posed sub-channel and power allocation algorithms, the capacity is distributed fairly
among users according to the rate ratio.
