Abstract: Multiple short transmission time intervals (TTIs), each of which is shorter than 1 ms, may be configured in a subframe. A user equipment (UE) may transmit a demodulation reference signal (DM-RS) which is shared among different UEs to an eNodeB (eNB). In this case, the DM-RS may be transmitted in a reference TTI, which is one short TTI among the multiple short TTIs, and the reference TTI may be indicated by downlink control information (DCI) received from the eNB. Alternatively, a UE may transmit the DM-RS which is shared among different short TTIs to the eNB.

The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.

Abstract: A method and apparatus for using multiple numerologies in a wireless communication system is provided. A user equipment (UE), specifically UE supporting ultra-reliable low-latency communication (URLLC), uses a first numerology in a first numerology resource unit group (NRG) with a reference subcarrier spacing, switches from the first numerology to a second numerology, and uses the second numerology in a second NRG with a specific subcarrier spacing different from the reference subcarrier spacing. The first NRG is a set of frequency and time resources based on the first numerology, and the second NRG is a set of frequency and time resources based on the second numerology.

Abstract: The present disclosure provides a method of transmitting a Physical Broadcasting Channel (PBCH) by a base station in a wireless communication system. Particularly, the method may include generating a PBCH payload including bits indicating a frame in which the PBCH is transmitted; scrambling at least some of the bits included in the PBCH payload using second and third least significant bits among the bits; and transmitting the bits of the PBCH payload including the at least some scrambled bits to a user equipment.

Abstract: A default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.

Abstract: A method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the CORESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.
