Method and apparatus of flexible data transmissions and receptions in next generation cellular networks
First Claim
1. A method for obtaining numerology information by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) based on a first subcarrier spacing;
receiving, from the base station, a master information block (MIB) on a physical broadcast channel (PBCH) based on the first subcarrier spacing, wherein the MIB includes information corresponding to a second subcarrier spacing from a set of subcarrier spacings and the set of subcarrier spacings is identified based on a frequency band on which the MIB is received;
andreceiving, from the base station, a system information block (SIB) based on the second subcarrier spacing.

Abstract
A communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for Internet of Things (IoT) is provided. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method for obtaining numerology information by a user equipment (UE) includes detecting synchronization signals, obtaining first numerology information for the synchronization signals, decoding a physical broadcast channel (PBCH) based on the first numerology information, obtaining second numerology information for a physical downlink control channel (PDCCH) according to a result of the decoding, and receiving control information on the PDCCH based on the second numerology information.
