Abstract: The present specification provides a method for transmitting uplink data (UL data) requiring a low latency in a wireless communication system. The method performed by a terminal comprises: receiving control information related to a contention-based PUSCH zone from a base station; and transmitting uplink data to the base station on the basis of the received control information. The contention-based PUSCH zone is a resource area where uplink data of the terminal can be transmitted without allocation of a UL grant from the base station. Further, in order to distinguish between kinds of specific procedures performed by the terminal, the control information includes procedure-distinguishing information allocated for each kind of the specific procedures.

Abstract: A method performed by a user equipment (UE) that operates according to a first indicator and a second indicator is provided. When the UE is in a radio resource control (RRC) connected state with a first communication system and is in a state of idle mode with a second communication system, the UE receives a first message including the first indicator and the second indicator from the first communication system. The first indicator instructs the UE to perform association processes with a base station of the second communication system. The second indicator instructs the UE to operate in a power saving mode with the base station of the second communication system. After the UE performs the association processes, the UE switches to an RRC-idle mode state with the first communication system and enters the power saving mode from the idle mode with the second communication system.

Abstract: The present disclosure relates to an operating method of a terminal for transceiving data to/from a base station in a system that supports a plurality of component carriers. The method includes receiving, from the base station, downlink control information (DCI) masked using a terminal identifier (cell-radio network temporary identifier (C-RNTI)) or a semi-persistent scheduling terminal identifier (SPS C-RNTI) through a physical downlink control channel (PDCCH); determining a component carrier for transceiving data to/from the base station; and transceiving data to/from the base station through the determined component carrier. The determining includes determining the component carrier which has received the PDCCH as a component carrier for receiving downlink data, and determining an uplink component carrier linked with the component carrier which has received the PDCCH as a component carrier for transmitting uplink data.

Abstract: In this disclosure, methods for antenna combining to meet the pilot requirement of the massive MIMO system, and apparatuses for the same are provided. In a user equipment (UE) perspective of view, the UE transmits first pilot signals via each of multiple antennas of the UE, and receives antenna combining information from a base station. Here, the antenna combining information combines the multiple antennas into one or more antenna groups based on the first pilot signals, and each of orthogonal sequences is allocated to each of the antenna groups. The UE transmits second pilot signals using the allocated orthogonal sequences for each of the antenna groups. The second pilot signals can be used for estimating downlink channel from the base station to the UE.
