A base station ( 103 ) assigns a set of mobile stations ( 101 ) to a group wherein the group will share a set of radio resources ( 770 ). A shared control channel information element ( 501 ) is sent to the group of mobile stations ( 101 ) and provides a bitmap having fields for group ordering ( 511 ), resource allocations ( 530 ), continuation resources ( 540 ) for HARQ, and an ordering pattern ( 513 ). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field ( 54 ) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index ( 601 ) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.
