摘要： 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.

摘要： A base station divides a subframe into a downlink time duration for downlink, an uplink time duration for uplink, and a guard period between the downlink time duration and the uplink time duration. The base station transmits a downlink control channel including information on a downlink packet duration allocated for downlink transmission of a terminal and information on an uplink packet duration allocated for uplink transmission of the terminal to the terminal in the downlink time duration.

摘要： A communication method of a terminal and a communication method of a base station for a direct communication link between terminals are disclosed. A base station schedules a reference terminal to transmit a ranging code, and schedules target terminals to receive the ranging code. The reference terminal measures the ranging code received from the target terminals, and transmits a ranging code measurement result to the base station. The base station selects a terminal from among the target terminals to form the direct communication link with the reference terminal among the target terminals based on the ranging code measurement result.
