Abstract: Example methods and apparatus to perform assignments in wireless communications are disclosed. A disclosed example method to receive resource assignments at a mobile station involves receiving an assignment message from a network and identifying radio block periods assigned to the mobile station. At least one of the assigned radio block periods is separated from a next occurring one of the assigned radio block periods by at least one non-assigned radio block period. The example method also involves processing downlink transmissions from the network based on the assigned radio block periods.
