Abstract :
We investigate round-robin scheduling for time-varying channels with a strict SINR constraint and limited feedback. The presented algorithm aims at scheduling the users at identical slots over different blocks. The algorithm allocates the users using orthogonal beamforming based on the quantized feedback provided by the users. The feedback consists of the estimated energy that is necessary to fulfill the SINR constraint. In order to fulfill the SINR constraint, the available transmit energy is distributed between the users based on their feedback. The performance of the algorithm is demonstrated through simulations.
