A distributed antenna system comprises users; remote radio heads ( Fig. 2 ) which are to be divided into clusters; and a central base station (CBS) (430) including a CBS processor (438), a CBS memory 440), a user ordering module (432), and a user scheduling and cluster formation module (434). The user ordering module (432) is configured to order the users (410) in decreasing values of proportional fair scheduling metrics to provide a set of ordered users. The user scheduling and cluster formation module (434) is configured to schedule the users (410) according to the order of the users in decreasing values of proportional fair scheduling metrics; and for each user being scheduled according to the order of the users, pick up first N number of remote radio heads, in decreasing order of signal strength to the user being scheduled, which have not been picked up previously, to form a cluster of size N for the user being scheduled. |
