A timing control method performed by a terminal included in a communication network may include: configuring an initial timing reference based on time information obtained from the communication network; receiving a first downlink (DL) signal from a base station; based on the initial timing reference and the first DL signal, obtaining first transmission time information that is information on a timing when the first DL signal is transmitted by the base station and first reception time information that is information on a timing when the first DL signal is received by the terminal; determining a first timing advance (TA) value based on comparison between the first reception time information and the first transmission time information; and adjusting an uplink (UL) transmission timing for the base station based on the first TA value.

Method and apparatus for timing control in wireless communication system

An operation method of a base station in a communication system may comprise: transmitting first indication information to a terminal, the first indication information indicating use of a first CQI table among CQI tables; transmitting a first reference signal to the terminal; and receiving first CSI from the terminal, the first CSI including a first CQI index selected within the first CQI table based on the first reference signal, wherein the CQI tables include the first CQI table and a second CQI table, and a spectral efficiency indicated by at least one CQI index within the first CQI table is identical to a spectral efficiency indicated by at least one CQI index within the second CQI table.

Method and apparatus for channel state information feedback in communication system

A method for receiving a wireless signal, performed by a first communication node, may comprise: storing a wireless signal received by the first communication node as samples in a buffer; performing partial correlation operations on the stored samples by a plurality of partial correlators; performing a first FFT operation on results of the partial correlation operations; performing a cumulative product operation on results of the first FFT operation; performing a second FFT operation based on a result of the cumulative product operation; and performing synchronization estimation based on the results of the first FFT operation and a result of the second FFT operation.
