Abstract: There is provided a method for transmitting, by a transmitter, a signal through an unlicensed band channel. The transmitter transmits an initial signal through the unlicensed band channel to preoccupy the unlicensed band channel when the unlicensed band channel is in an idle status. The transmitter includes a first partial subframe transmitted after the initial signal in a frame burst depending to transmission timing of the initial signal. Further, the transmitter transmits the frame burst through the unlicensed band channel.

Abstract: Provided is a method of transmitting control information using a physical uplink shared channel (PUSCH) region in a system employing a multi-input multi-output (MIMO) antenna system in which transmission is performed through a plurality of layers. A method of transmitting a channel quality indicator (CQI)/precoding matrix indicator (PMI) using a PUSCH region in a system employing a MIMO antenna system in which transmission is performed through a plurality of layers includes encoding the CQI/PMI using one channel encoder, and transmitting the encoded CQI/PMI using some or all of the layers. Accordingly, it is possible to transmit uplink control information through a PUSCH region using a plurality of layers.

Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.
Abstract translation: 通过在使用多个载波的无线通信系统中配置控制信道来提供数据发送和接收。 用户设备（UE）可以监视公共搜索空间（CSS）和用户设备特定搜索空间（USS）内的物理下行链路控制信道（PDCCH）候选。 如果UE配置了跨载波调度，则当分别来自CSS和USS的两个PDCCH候选分别具有由同一无线电网络临时标识符（RNTI）加扰并且具有公共有效负载大小的循环冗余校验（CRC） 相同的第一控制信道单元（CCE）索引，则UE可以解释仅发送来自CSS的PDCCH，从而解决下行链路控制信息（DCI）检测的模糊性。

Abstract: Disclosed is a method for generating and transmitting a reference signal in a clustered DFT-spread OFDM transmission scheme. A method for generating and transmitting a DM-RS in a clustered DFT-spread-OFDM scheme comprises: a step of generating DM-RS sequences corresponding to the number of clusters allocated for an uplink transmission; and a step of mapping the generated DM-RS sequences to the relevant DM-RS symbol positions for each cluster. Accordingly, the method for generating and transmitting a reference signal according to the present invention, in which DM-RS sequences are allocated and transmitted on a cluster basis, uses a complete DM-RS sequence for each cluster, and therefore inter-cell interference can be weakened, and problems which might occur when applied to a multi-user MIMO (MU-MIMO) scheme can be solved.
