摘要： In a system supporting narrowband Internet of things (NB-IoT), a terminal maps an uplink reference signal to a plurality of resource elements in a scheduled resource allocation unit, and transmits the uplink reference signal mapped to the plurality of resource elements. Here, the scheduled resource allocation unit includes a first number of contiguous slots in a time domain and a second number of contiguous subcarriers in a frequency domain.

摘要： A transmission method of a base station is provided. The base station generates a first discovery signal block including a first PSS (primary synchronization signal) and a first SSS (secondary synchronization signal). The base station generates a second discovery signal block including a second PSS and a second SSS. Also, the base station transmits the first discovery signal block and the second discovery signal block.

摘要： A base station divides a subframe into a downlink time duration for downlink, an uplink time duration for uplink, and a guard period between the downlink time duration and the uplink time duration. The base station transmits a downlink control channel including information on a downlink packet duration allocated for downlink transmission of a terminal and information on an uplink packet duration allocated for uplink transmission of the terminal to the terminal in the downlink time duration.

摘要： A method in which a base station transmits a CSI (channel state information)-RS (reference signal) in a MIMO (multiple input multiple output) antenna system is provided. The base station periodically transmits a CSI-RS for first CSI to a terminal. The base station requests the terminal to transmit second CSI in a first subframe. When a CSI-RS occasion is configured, the base station transmits a CSI-RS for the second CSI to the terminal for a duration of the CSI-RS occasion from a second subframe or to the second subframe, which is a subframe after a first offset configured for CSI-RS transmission from the first subframe.

摘要： Provided are a method for generating a CSI report and a terminal thereof. The method for generating a CSI report includes: receiving a CSI-RS from a serving cell of a base station through at least one CSI-RS resource included in a CSI-RS occasion; and generating the CSI report based on the CSI-RS received through the at least one CSI-RS resource.

摘要： In an environment in which a macrocell and a plurality of small cells exist, a terminal receives a discovery signal from a first small cell adjacent to the terminal among the plurality of small cells. When the first small cell is in a predetermined state, the terminal measures RRM of the first small cell based on the discovery signal.
