摘要
In broadcast wireless systems, dynamic allocation of resources such as transmission power/rate, time slot and frequency is necessary. In this paper, we focus on dynamic resource allocation in the forward-link in a TDM/SS system, resources include power/rate, time slot and antenna beam. The proposed algorithm is based on achievable data rates from an information theoretic point of view. After a proper allocation of beam and time subslot to each user, power is allocated to the users in different channel states in a water-filling construction to maximize the overall transmitted data rate of the network with the minimum transmitted power.
