Abstract:

In this letter, we explore a limited feedback scheme for meeting the requirements that different users demand different communication rates. The main idea of this letter is to prioritize users by assigning different priority weights to the residual interference of each user. Then, by minimizing the weighted sum of residual interference, the optimal scheme for the allocation of feedback bits to support service differentiation is designed. Simulation results show that the proposed scheme can support service differentiation regarding communication rates and the degree of difference in communication rate between users can be flexibly adjusted by changing the weights.
