    摘要: A method of transmitting a scheduling request signal, wherein the scheduling request signal is used to request a radio resource for uplink transmission in a wireless communication system is provided. The method includes configuring a physical uplink control channel (PUCCH) for transmission of a scheduling request signal in a subframe, the subframe comprising two consecutive slots, a slot comprising a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols, the scheduling request signal being carried by a presence or absence of transmission of the PUCCH, wherein at least one SC-FDMA symbol is assigned for transmission of a sounding reference signal, and transmitting the scheduling request signal and the sounding reference signal in the subframe. Scheduling request signal can be transmitted without interference with other control signals such as sounding reference signal that are transmitted on the same control channel with the scheduling request signal.

    摘要: A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.

    摘要: A method for reducing retransmission overhead in a system based on the asynchronous channel-adaptive retransmission scheme is disclosed. If the possibility of performing data retransmission is high, the system provides a method for transmitting synchronous duration (SD) information. According to the method for transmitting the SD information, the system does not transmit scheduling information whenever receiving a retransmission request, and synchronously transmits data during a predetermined synchronous duration. Namely, the data can be retransmitted without using the scheduling information.

    摘要: A method for modifying a synchronous non-adaptive retransmission scheme to solve the limitation of the synchronous non-adaptive retransmission scheme is disclosed. A method for indicating not only the new data transmission but also the retransmission using a data scheduling message is disclosed. A method for determining whether there is an error in the ACK signal transmitted from a data reception end using another message to-be received later is disclosed. The retransmission method for a multi-carrier system includes: receiving a grant message including scheduling information for transmitting uplink data wherein a retransmission scheme for the uplink data is predetermined by a first retransmission scheduling, transmitting the uplink data according to the scheduling information and retransmitting the uplink data according to second retransmission scheduling by receiving the second retransmission scheduling information associated with the uplink data with retransmission request.
