1. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor configured to:
control the transceiver to receive, from a base station (BS), a radio resource control (RRC) reconfiguration message comprising a reconfiguration with synchronization,
control the transceiver to transmit, to the BS, a first message comprising a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), and a cell radio network temporary identity (C-RNTI) medium access control (MAC) control element (CE) based on the reconfiguration with synchronization, control the transceiver to receive, from the BS, a first physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH), wherein:
for the case when the BS receives the PRACH and does not receive the PUSCH, the first PDCCH is a PDCCH addressed to random access RNTI (RA-RNTI) and the PDSCH includes a fallback random access response (RAR); and
for the case when the BS receives the PUSCH, the first PDCCH is a PDCCH addressed to a C-RNTI corresponding to the C-RNTI MAC CE and the PDSCH includes an absolute timing advance command MAC CE,
determine that a RAR reception is successful based on at least one of the fallback RAR or the PDSCH,
when a discontinuous reception (DRX) is configured for the terminal via a RRC signalling, determine that an active time for the DRX includes a time while a second PDCCH indicating a new transmission addressed to the C-RNTI corresponding to the C-RNTI MAC CE has not been received after determining that the RAR reception is successful, and
monitor the second PDCCH during the active time.
