Abstract: The present invention provides an uplink signal transmission/receiving method and an apparatus therefor, and a downlink signal transmission/receiving method and an apparatus therefor. In a half duplex frequency division duplex (HD-FDD), when uplink transmission and downlink receipt are performed on the same subframe or neighboring subframes, a user equipment drops one of the uplink transmission and the downlink receipt according to a priority, and performs only transmission which is not dropped. The priority includes periodically unavailable resources, that is, aperiodic resources, taking priority over periodically available resources. If the uplink transmission is periodic, for example assigned in a semi-static manner or in a semi-persistent manner, and a downlink transmission is aperiodic, for example assigned dynamically, the user equipment drops the uplink transmission and performs the downlink receipt.

Abstract: Disclosed herein is a method and apparatus for transmitting/receiving a signal in a wireless communication system supporting NB-IoT. An eNB provides a user equipment (UE), for which NB-IoT is not configured, with information about frequency bands (anchor RBs) possibly having a synchronization signal for NB-IoT (hereinafter, an NB-IoT SS). When the eNB transmits a downlink signal to the UE, it may puncture the downlink signal on an RB having the NB-IoT SS, based on the information. When the UE transmits an uplink signal, it may puncture the uplink signal on an RB having the NB-IoT SS, based on the information.

Abstract: The present invention relates to a method of measuring the position of a terminal by using a heterogeneous network signal. The method comprises receiving transmission time information that represents a time at which a signal for measuring the position of a terminal is transmitted; receiving a first signal from a reference cell at a time represented by the transmission time information; receiving a second signal from a measurement cell at a time represented by the transmission time information; calculating the difference between the time at which the first signal is received and the time at which the second signal is received to generate measurement information; and reporting the measurement information.

Abstract: A method and apparatus for transmitting a Wi-Fi signal in a wireless communication system is provided. A device supporting long-term evolution in unlicensed spectrum (LTE-U) transmits a LTE signal, and transmits the Wi-Fi signal. The Wi-Fi signal may be transmitted by various methods, i.e. by being emulated in the LTE signal, by using a Wi-Fi processor which is embedded in a LTE processor, or by using a Wi-Fi processor which is individual to a LTE processor.
