Abstract: An operation method of a terminal in a non-orthogonal multiple access (NOMA) based communication system includes receiving information on a NOMA resource sequence allocated by a base station from the base station; and transmitting data to the base station by using a NOMA resource indicated by the information on the NOMA resource sequence in each data symbol or each data symbol group. Also, the NOMA resource sequence may indicate at least one NOMA resource in a NOMA resource set.

Abstract: An operation method of a terminal in a communication system may include receiving bandwidth part (BWP) change information from a base station in a BWP i; changing an operation BWP of the terminal from the BWP i to a BWP j even when a transmission and reception procedure of first data in the BWP i is not completed at a BWP changing point indicated by the BWP change information; and performing a data transmission and reception procedure of second data in the BWP j, wherein the BWP i and the BWP j are different BWPs, and i and j are different integers.

Abstract: Disclosed are a method and an apparatus for enhanced conditional handover (CHO). An operation method of a base station may comprise: receiving a measurement report message from a terminal; transmitting a CHO request message to one or more candidate target cells; receiving a CHO request ACK message from the one or more candidate target cells; and transmitting an RRC reconfiguration message including CHO status report configuration information to the terminal, wherein the CHO status report configuration information requests transmission of information for determining a target cell to which terminal is likely to be handed over among the one or more candidate target cells.
