    • The present invention relates to a fractional RB (Resource Block) allocation method which enables resource allocation in a unit smaller than RB to improve the capacity of VoIP (Voice over Internet Protocol) in an LTE (Long Term Evolution) system. That is, the present invention introduces a resource arrangement method which allows different users to share the same resource, without even using an SDMA, and a method for informing the fractional RB allocation and how to use the same. A method for introducing multiplexation into an RB and changing the RE arrangement is proposed to support the downlink fractional RB allocation. A method for changing the RE arrangement is also proposed to support the uplink fractional RB allocation. According to the present invention, to provide a consistent service with a small amount of traffic generated as in the VoIP, resources of a smaller amount than a single RB can be used for a terminal with a good channel state. In the present invention, the occupancy of resources for the terminals of an excellent channel state is reduced so that the capacity of the VoIP can be improved.

    • In a relay based wireless communication system, a method for transmitting an uplink backhaul of a relay node includes obtaining scheduling information for an uplink backhaul sub-frame through a downlink backhaul control channel from a base station, and performing a rate matching and mapping of data by regarding at least one predefined symbol as a blank symbol. The predefined symbol is located at a front part or a rear part of the scheduled uplink backhaul sub-frame. The transmitting method further includes performing a multiplexing of the uplink backhaul sub-frame, and transmitting the multiplexed uplink backhaul sub-frame. This method can eliminate an overlap of transmission and reception timing in a relay node due to an RF transmission/reception switching time delay. Also, the method can make better use of wireless backhaul resources and minimize an influence on conventional systems by offering the compatibility with conventional uplink and downlink sub-frame structures.
