Abstract
An operation method of a terminal in a wireless communication system is provided. The operation method includes receiving a subcarrier spacing configuration and cyclic prefix information from a base station through higher layer signaling; and when the subcarrier spacing configuration indicates subcarrier spacing of 60 kHz and the cyclic prefix information indicates an extended cyclic prefix, determining a slot format with the extended cyclic prefix based on a slot format with a normal cyclic prefix.
Claims12
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), a subcarrier spacing configuration indicating a subcarrier spacing of 60 kHz and cyclic prefix information indicating an extended cyclic prefix through higher layer signaling;
- determining a first value of a slot format indicator, for a symbol having the extended cyclic prefix to be determined by the UE as a flexible symbol in case that at least one of symbols having a normal cyclic prefix and overlapping the symbol is a flexible symbol according to a slot format indicated by the first value, an uplink symbol in case that all symbols having the normal cyclic prefix and overlapping the symbol are uplink symbols according to the slot format indicated by the first value, and a downlink symbol in case that all symbols having the normal cyclic prefix and overlapping the symbol are downlink symbols according to the slot format indicated by the first value;
- and
- transmitting, to the UE, the slot format indicator with the first value.

A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), a slot format information for a first subcarrier spacing configuration through higher layer signaling;
- determining a second subcarrier spacing configuration, for 2n consecutive symbols for the second subcarrier spacing configuration to be determined by the UE as flexible symbols in case that a symbol constituting a slot format based on the slot format information and corresponding to the 2n consecutive symbols is a flexible symbol, uplink symbols in case that the symbol constituting the slot format based on the slot format information and corresponding to the 2n consecutive symbols is an uplink symbol, and downlink symbols in case that the symbol constituting the slot format based on the slot format information and corresponding to the 2n consecutive symbols is a downlink symbol;
- and
- transmitting, to the UE, a bandwidth part configuration including the second subcarrier spacing configuration from the base station through higher layer signaling.
