Abstract:
|
This paper deals with the spatio-temporal scheduling of a set of
users for downlink transmission in a cell where the base station is
provided with multiple antennas. Two main issues are addressed:
how the users are distributed into space-time groups and how the
available power is allocated among the users within a group. Since
the former is an NP-complete combinatorial problem, we develop
fast and low-complexity algorithms, which might be capable to
fulfill the real-time requirements of a practical scheduling scheme.
Regarding the power allocation, we consider different fairness criteria
under the capacity point of view. To be precise, we compare
the alternatives of equal rate and maximum sum rate with our proposed
equal proportional rate solution. |
