摘要:
Disclosed is a method for enabling a relay node to transmit uplink control information. The relay node can receive resource allocation information and sequence information according to the transmission format of a physical uplink control channel set from a base station in advance. Additionally, the relay node can transmit the uplink control information, to which a sequence corresponding to the received sequence information is applied, in at least one slot of a resource area, which is indicated by the received resource allocation information, through a fixed number of symbols.

The present invention relates to a method for allocating a relay backhaul resource in a wireless communication system and to an apparatus for same. In detail, the present invention provides a signal-receiving method in which a terminal receives a signal in a wireless communication system, and to an apparatus for same, wherein the method comprises a step of receiving, from a base station, information on one or more first resource blocks (RB) allocated for a relay, a step of receiving resource allocation information through a control channel from the base station, and a step of receiving a predetermined resource block indicated by the resource allocation information among logically continuous second resource blocks. The second resource blocks are logically continuous when excluding said one or more first resource blocks from the entirety of the resource block.

A method and apparatus for transmitting an aperiodic sounding reference signal (SRS) in a wireless communication system is provided. The method include receiving a downlink control information (DCI) format including a triggering signal for triggering a transmission of an aperiodic SRS from a base station (BS) via a physical downlink control Channel (PDCCH), blind-decoding the PDCCH in a UE-specific search space, and transmitting the aperiodic SRS triggered based on the triggering signal to the BS.

Disclosed is a method in which a relay node transmits/receives signals via a specific downlink subframe and a specific uplink subframe. The relay node may consider the propagation delay in accordance with the distance between a base station and the relay node to set a subframe timing for transmitting/receiving signals to/from the base station. The relay node may further consider the delay time of 0.5 symbol, 1 symbol or the like in addition to said propagation delay in the event of setting a downlink receiving timing. Setting an uplink subframe timing of the relay node can be divided into the event the timing is set on the basis of a backhaul link and the event the timing is set on the basis of an access link. In the event the timing is set on the basis of the access link, the propagation delay can be double that of the event the timing is set on the basis of the backhaul link, which should be considered in setting the timing.

A method of transmitting a signal using a prescribed frame structure in a wireless communication system is disclosed. A mobile station is able to transmit or receive a signal using a frame structure with a CP length corresponding to ¼ of a useful symbol. Moreover, the mobile station is able to transmit or receive a signal using a frame structure with a CP length corresponding to ¼ of a useful symbol, which is designed to mutually coexist without causing collision or interference with another frame structure with a different CP length. In this case, a channel bandwidth of the prescribed frame structure is 7 MHz.

Disclosed are an apparatus and a method for performing communication using a half-frequency division duplex (H-FDD) frame structure in a mobile communication system. A user equipment for performing communication using an H-FDD frame structure according to the present invention comprises an RF unit in which each user equipment group receives and transmits signals using the H-FDD frame structure wherein the order of the downlink zone and uplink zone are reversely allocated to each of the groups. The downlink zone and uplink zone, which are allocated to each of the user equipment groups in the H-FDD frame structure, include a sub-frame wherein one or more symbols are allocated to idle time slots or are punctured. Each of the user equipment groups can receive and transmit signals using symbols that are not allocated to the idle time slots or are not punctured in the sub-frame.

A method for performing communication using a frame structure that supports a half-frequency division duplex (H-FDD) operation and a device using the same are disclosed. A base station performs resource allocation scheduling to support H-FDD user equipment operation in a mobile communication system. For example, the base station allocates first, second and last uplink subframes for idle subframes within a specific frame or punctures them, so that the H-FDD user equipment does not use the uplink subframes. The base station transmits the scheduled resource allocation information to the user equipment through a superframe header, a preamble and a MAP. The user equipment which has received the scheduled resource allocation information (subframe index and location that can be used by the user equipment) transmits and receives a signal based on the resource allocation information.
