Abstract
A base station for use in a wireless network that communicates with mobile stations according to the IEEE 802.16m standard. The base station transmits unicast data and E-MBS data in the downlink to mobile stations using physical resource units (PRUs) that are partitioned into a plurality of frequency partitions. The base station transmits E-MBS data using a first set of PRUs in at least a first common frequency partition, wherein the first set of PRUs are also used by at least a second base station to transmit E-MBS data. The base station further transmits unicast data using a second set of PRUs, wherein the second set of PRUs are randomized with respect to PRUs used by the at least a second base station to transmit unicast data.
