Abstract: A method for user equipment (UE) to receive a reference signal in a cellular mobile communication system supporting narrowband Internet of Things (NB-IoT) is disclosed. To this end, the UE receives, via at least one first subframe, a narrowband reference signal (NRS) for signal demodulating or measurement in NB-IoT and receiver, via at least one second subframe, a narrowband positioning reference signal (NPRS) for location-based measurement in the NB-IoT, wherein information on the at least one second subframe is received from a base station as configuration information of the NPRS, and, in accordance with the configuration information of the NPRS, the UE operates by assuming that the NRS is not transmitted in a subframe configured with the second subframe.

Abstract: Disclosed is a method for a terminal to transmit an uplink data signal in a narrowband wireless communication system. Specifically, the method comprises the steps of: receiving, from a base station, a downlink control signal including resource allocation information for resource blocks continuously allocated for the uplink data signal within allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein the continuously allocated resource blocks are updated to include a center resource block, when the allocable resource blocks include the center resource block of a system bandwidth.

Abstract: Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.

Abstract: This specification provides a long PUCCH using multiple slots in a wireless communication system. The method is performed by a user equipment and includes receiving first information about a TDD UL-DL slot configuration from a base station, receiving, from the base station, second information including a first parameter for a number of slots used for a transmission of the long PUCCH and a second parameter for a duration of a PUCCH symbol within a PUCCH slot, determining the multiple slots for transmitting the long PUCCH based on the first information and the second information, and transmitting the long PUCCH to the base station over the determined slots.

Abstract: A method and apparatus for performing uplink (UL) transmission in a wireless communication system is provided. A second user equipment (UE) wakes up for transmission of UL data, searches a first UE which is capable of downlink (DL) transmission to the second UE, acquires information for transmission of the UL data, and transmits the UL data to a network by using the acquired information. The second UE may only be capable of UL transmission to the network and may not be capable of DL reception from the network. Alternatively, the second UE may be capable of UL transmission to the network and may be capable of synchronization from the network.
