Abstract: A method by a terminal in a wireless communication system is provided. Downlink control information including modulation and coding scheme (MCS) information is received from a base station. A number of information bits are identified based on the downlink control information. A transport block size (TBS) is identified based on the number of information bits and a TBS candidate set. The TBS candidate set includes values separated by an interval among a plurality of intervals. Each of the plurality of intervals is a multiple of 8. A first interval between first consecutive values included in the TBS candidate set is larger than a second interval between second consecutive values included in the TBS candidate set. The first consecutive values are greater than or equal to a predetermined value, and the second consecutive values are less than the predetermined value.

Abstract: A method of a first communication device for removing a self-interference signal in a wireless communication system is provided. The method includes receiving a signal having a size less than a first threshold value from a second communication device in a first interval within a first frame, transmitting a first signal to a third communication device in the first interval, and estimating a self-interference channel through which the self-interference signal is transmitted based on the signal received in the first interval and the first signal transmitted in the first interval. The self-interference signal is a signal transmitted by the first communication device and is received by the first communication device through the self-interference channel.

Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The method includes identifying whether a channel forecast value is valid, the channel forecast value being acquired based on applying a learning algorithm to an input comprising channel values estimated based on first reference signals (RSs) received from a base station, transmitting, to the base station, an RS request message for requesting an update of the learning algorithm, based on the determining that the channel forecast value is invalid, receiving, from the base station, second RSs of an RS density determined based on the RS request message, generating an updated learning algorithm based on channel values estimated from the second RSs, and transmitting channel forecast information acquired based on the updated learning algorithm to the base station.
