    Abstract: A method of allocating control information in a wireless communication system is provided. The method includes: allocating essential control information of a first system to a first sub-frame in a frame including a plurality of sub-frames each of which comprises a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and allocating essential control information of a second system to an nth sub-frame in a fixed position from the first sub-frame (where n is an integer satisfying n>1). Accordingly, in a frame supporting heterogeneous systems, essential control information can be fixedly allocated to a specific position while maintaining the number of system switching points, at which switching occurs between the systems, to one even if a radio resource allocation amount changes between the systems, and thus the essential control information that must be received by all user equipments can be effectively provided without the increase of overhead.

    Abstract translation: 提供了一种在无线通信系统中分配控制信息的方法。 该方法包括：在包括多个子帧的帧中的第一子帧中分配第一系统的基本控制信息，每个子帧包括多个正交频分复用（OFDM）符号; 并且将第二系统的基本控制信息从第一子帧（其中n是满足n> 1的整数）分配给固定位置的第n个子帧。 因此，在支持异构系统的帧中，即使在系统之间的无线资源分配量发生变化的情况下，也可以将基本控制信息固定地分配给特定位置，同时将系统之间进行切换的系统切换点的数量保持为一个 因此可以有效地提供所有用户设备必须接收的基本控制信息，而不增加开销。

    Abstract: Methods and devices for transmitting or receiving channel quality control information through a physical uplink shared channel (PUSCH) in a wireless access system that supports hybrid automatic retransmit request (HARQ) are discussed. The method in one embodiment performed by a user equipment (UE) includes receiving a physical downlink control channel (PDCCH) signal including an initial uplink grant, transmitting uplink data using two transport blocks based on the initial uplink grant, receiving a negative acknowledgement (NACK) information for one of the two transport blocks, and transmitting a channel quality control information along with the one of the two transport blocks which is retransmitted according to the NACK information or a new transport block through the PUSCH to which the HARQ is applied. A number of coded symbols required to transmit the channel quality control information (Q′) is calculated based on the initial uplink grant.
