摘要： A packet buffering apparatus and method in a multi-hop relay system supporting hop-by-hop retransmission are provided. In the buffering apparatus and method, a first buffer buffers a user packet until the user packet is successfully transmitted to a next node, and a second buffer buffers the user packet until the user packet is successfully transmitted to an MS, after the user packet is successfully transmitted to the next node. Accordingly, time delays and transmission costs are reduced.

摘要： Disclosed is a system and method for transmitting/receiving a signal in a communication system. In the system and method, a base station transmits data to a first relay station, which is connected directly thereto from among relay stations belonging to a first relay station group, through a first frame interval, and transmits data to a second relay station, which is connected directly thereto from among relay stations belonging to a second relay station group, through a second frame interval subsequent to the first frame interval. In the first frame interval or the second frame interval where no data is received from the base station, each of the first and second relay stations transmits data to a next relay station connected directly thereto within the same relay station group, and communicates data with a mobile station in direct communication therewith.

摘要： Provided is an apparatus and method for transmitting/receiving signals in a communication system. A base station allocates a quasi-dedicated control channel (QDCCH) to a first mobile station (MS), and allocates the QDCCH allocated to the first MS, to a second MS for a preset time. An MS receives a QDCCH allocated from the base station. If there is data to transmit to the base station, the MS determines whether the QDCCH is allocated to another MS different from the MS. If it is determined that the QDCCH is allocated to the MS itself, the MS transmits the data to the base station over the QDCCH.

摘要： Disclosed is a method for requesting allocation of uplink bandwidth for uplink data transmission and allocating the uplink bandwidth in a wireless communication system. In the method, when a number of uplink bandwidth allocation requests having occurred in a certain interval is different from that of scheduled uplink bandwidth allocation requests, uplink bandwidths are allocated to the extent that the occurred uplink bandwidth allocation requests can be implanted. Herein, the uplink bandwidth allocation requests occur in an MS according to services. Accordingly, as the uplink bandwidth allocation requests increase, uplink bandwidths also increase. However, as the uplink bandwidth allocation requests decrease, uplink bandwidths also decrease.

摘要： A method and apparatus for removing interference from a UpLink (UL) signal in a Time Division Duplex (TDD) system are provided. The method includes determining whether a section for receiving an UpLink (UL) signal from the MS overlaps with sections for sending a DownLink (DL) signal of neighbor BSs in service, the neighbor BSs sending the DL signal to another MS, when the UL signal section overlaps with the DL sections of the neighbor BSs, detecting DL transmit signal information from the neighbor BSs transmitting in the overlapping sections, and removing interference from the UL signal using the detected transmit signal information. Accordingly, the accuracy of detecting the signal from the MS can be raised without having to adopt the complex resource allocation scheme to avoid the interference of the neighbor BSs.

摘要： A system is provided for performing location update in a wireless mobile communication system that uses an Internet protocol (IP) address and is classified as at least one paging group. A serving base station (BS) sends a message including an identifier of a paging group where the serving BS is located, determines whether there is a change in IP subnet of a mobile station (MS) upon receipt of a location update request from the MS, and upon recognizing a change in IP subnet of the MS, stores information on a new IP subnet and notifies the change in the IP subnet to the MS. Upon detecting a need for location update, the MS sends a request for location update to a serving BS, and receives a location update success notification and an allocated temporary IP address from the serving BS.

摘要： A mobile node (MN) connected to a first radio network transmits location information of a correspondent node (CN) to a base station (BS) constituting a second radio network. The BS determines whether it can establish a data transmission path to the CN, using network contract information of the second radio network and the location information of the CN. If the BS can establish the data transmission path, it determines a data transmission path to the CN using the network contract information of the second radio network and the location information of the CN, and transmits an identifier (ID) of the second radio network and service connection possibility/impossibility information to the MN. The MN establishes a connection to the second radio network, and communicates with the CN via the data transmission path.

摘要： A method quickly resuming a downlink service in a hard handover in a cellular mobile communication system. To provide the fast downlink service to an MS during a hard handover from an OBS to an NBS, the NBS receives handover user information from the OBS, and generates an MS temporary ID using the handover user information to identify the MS. If user data is generated for the MS before a connection is established for traffic transmission between the MS and the NBS, the NBS transmits the user data to the MS on an HCCH using the MS temporary ID.
