1. A method for receiving unicast control information that is specific to a mobile station within a multicast group, the method comprising:
- at the mobile station;
communicating with a base station using an orthogonal frequency division multiplexing (OFDM) or broadband OFDM based technology, wherein the mobile station is temporarily grouped within a first multicast group of a plurality of multicast groups, wherein the first multicast group is defined by a first multicast group ID of a plurality of multicast group IDs, wherein the membership in the first multicast group is updated by unicast signaling; and
receiving a bitmap in a multicast group message addressed to the first multicast group ID, wherein the multicast group message is received by multiple mobile stations temporarily grouped within the first multicast group, wherein the multicast group message includes unicast control information that is specific to the mobile station and is located at a specific bit position of the bitmap, wherein the bitmap addresses individual users of the first multicast group with respective bit positions of the bitmap known from the unicast signaling update of the first multicast group, and wherein the mobile station disregards bitmaps associated with multicast groups defined by second multicast group IDs other than the first multi cast group ID.

Abstract
A method and system for allocating shareable wireless transmission resources. A resource pool is established. The resource pool is divided into a plurality of physical layer allocation units usable for wirelessly transmitting control information and traffic data. The allocation units are assigned at the media access control layer for the wireless transmission of the control information and traffic data. The system and method of the present invention also allows mobile stations to be dynamically grouped into multicast groupings to reduce system overhead resource requirements.
