摘要： The present invention relates to a preamble allocation method and a random access method in a mobile communication system. In the present invention, one among preamble resources is allocated to specific mobile stations in advance, before random access. The mobile stations request random access by transmitting a preamble based on the pre-allocated preamble resource to a base station. It is therefore possible to prevent collision caused by the fact that other mobile stations transmit the same preamble.

摘要： When a terminal generates an uplink signal in a communication system, the terminal hops a sequence for differentiating itself from another terminal with time. The terminal generates the uplink signal by multiplying a transmission symbol by a sequence of a transmission time corresponding to the transmission symbol.

摘要： Provided is an error correcting method that can provide improved error correction efficiency in a multimedia broadcast/multicast service (MBMS) by marking the presence of an error in a Protocol Data Unit (PDU) with an error instead of discarding the erroneous PDU in an MBMS terminal of the MBMS system, which performs error correction in an application layer, and transmitting the erroneous PDU together with a PDU without an error to the application layer, and an error correction apparatus employing the method. The MBMS terminal includes: a radio link control (RLC) protocol processor configured to receive PDUs generated from the reception data, generate service data units (SDUs) by combining the PDUs, mark whether there is an SDU recovered from a PDU with an error, and output the SDUs; and a packet data convergence protocol (PDCP) processing means configured to receive and deliver the SDUs.
