Abstract: Methods and apparatus are provided for performing a handover by a serving base station in a communication system. A handover request message is received from a mobile station. A first handover response message is transmitted to the mobile station. The first handover response message includes a list of at least one neighbor base station. A handover indication message including a value of a handover indication type field is received. The value is determined by the mobile station from among at least two values individually indicating at least one of a handover cancel and the handover rejection. The value representing the handover cancel indicates that the mobile station intends to cancel a handover procedure, and the value representing the handover rejection indicates that the mobile station intends to reject performing handover with any of the at least one neighbor base stations in the list.

Abstract: An apparatus and method for configuring a Relay-Frame Control Header (R-FCH) transmitted in an intermediary link area in a multi-hop relay Broadband Wireless Access (BWA) communication system are provided. The method includes determining a modulation scheme of a Relay Station (RS) Downlink (DL)-MAP (or simply referred to as R-MAP) in consideration of a channel state with the RS while an initial network entry process is performed by the RS or while communicating with the RS in a Base Station (BS)-RS area where communication is made with RSs connected to the BS and transmitting a message including the determined modulation scheme to the RS. Accordingly, a Modulation and Coding Scheme (MCS) on the R-MAP can be dynamically changed according to a channel state between an RS and a BS, thereby enabling effective use of resources.
