Abstract

Sharing radio resources between multiple types of users is disclosed that form user groups including first type users and second type users. A plurality of resource blocks is assigned to the user group after which, a group setup message is transmitted to each user in the user group. This group setup message includes group parameters and identification of the resource blocks. A group grant message is also issued to each user in the user group, which provides group information allowing the resource blocks to be shared between the first and second user types.
