Abstract: An apparatus and method in a heterogeneous wireless communication system reconnect a Mobile Station (MS) to a previously connected cell upon occurrence of a Radio Link Failure (RLF) in a current cell when a portion of a coverage of the second cell is included in a coverage of the first cell. A Mobile Station (MS) stores system information of a first Base Station (BS) of a first cell when performing handover from the first cell to a second cell. When changed system information of the first BS is received from a second BS of the second cell, the MS updates the stored system information using the changed system information. When detecting that a connection with the second cell is lost prior to a handover from the second cell, the MS performs reconnection to the first BS using the stored system information.

Abstract: The present invention relates to a method and a system for requesting the allocation of bandwidth in a multi-hop relay environment. The present invention relates to a method for requesting bandwidth of a relay node in the multi-hop relay environment and a method for allocating bandwidth of a base station. In the invention, single piggybacking and multiple piggybacking based on approval-processing sub-headers are discriminated from single piggybacking and multiple piggybacking based on extensible sub-headers. Therefore, the bandwidth-requests for each CID from the base station are integrated and managed for each relay so that the message transmission and reception load may be reduced and the allocation of bandwidth may be optimized.
