Résumé:
For multi-antenna Orthogonal Frequency-Division
Multiple Access (OFDMA) based multicell networks, the channel
state information (CSI) of all users is required to share among
base stations in order to perform distributed power allocation.
However, the amount of feedback increases with the number of
users, base stations, subcarriers and antennas. Therefore, it is
important to perform a selection at the user side to reduce the
feedback load and the complexity of resource allocation. In this
letter, we propose adaptive reduced feedback links by choosing
the users based on their approximate signal to interference noise
ratio (SINR) and their locations in the cell to satisfy users’ rate
constraints. We illustrate the performance results of reduced
feedback links by employing distributed resource allocation with
link adaptation.
