Abstract
A cell information transmission/reception method and an apparatus are provided for use in a wireless communication system. A cell information transmission method of a base station in a wireless communication system according to the present disclosure includes transmitting, by the base station, system information to a terminal, the system information including a neighbor cell list having at least one cell Identifier (ID), and transmitting, by the base station, cell information on at least one cell selected according to a predetermined rule based on the neighbor cell list to the terminal.
Claims22
A cell information transmission method by a base station in a wireless communication system, the cell information transmission method comprising:
- generating, by at least one processor of the base station, a neighbor cell list having at least one cell identifier (ID) and at least one index corresponding to each of the at least one cell ID;
- transmitting, by a transceiver of the base station, to a terminal, a first message including a system information block, the system information block including the neighbor cell list;
- selecting, by the at least one processor, at least one cell ID from the neighbor cell list based on a predetermined rule;
- and
- transmitting, by the transceiver, to the terminal, a second message including the at least one index corresponding to the selected at least one cell ID via a physical downlink control channel (PDCCH).
A cell information reception method by a terminal in a wireless communication system, the cell information reception method comprising:
- receiving, by a transceiver of the terminal, from a base station, a first message including a system information block, the system information block including a neighbor cell list having at least one cell identifier (ID) and at least one index corresponding to each of the at least one cell ID;
- receiving, by the transceiver, from the base station, a second message including the at least one index corresponding to at least one cell selected from the neighbor cell list based on a predetermined rule via a physical downlink control channel (PDCCH);
- and
- determining, by at least one processor of the terminal, the cell based on the neighbor cell list received in the first message and the at least one index received in the second message.
A base station transmitting cell information in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive signals to and from a terminal;
- and
- at least one processor configured to:
- generate a neighbor cell list having at least one cell identifier (ID) and at least one index corresponding to each of the at least one cell ID,
- control the transceiver to transmit a first message including a system information block to a terminal, the system information block including the neighbor cell list,
- select at least one cell ID from the neighbor cell list based on a predetermined rule, and
- control the transceiver to transmit a second message to the terminal including the at least one index corresponding to the selected at least one cell via a physical downlink control channel (PDCCH).
A terminal receiving cell information in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals to and from a base station;
- and
- at least one processor configured to:
- control the transceiver to receive a first message including a system information block from a base station, the system information block including a neighbor cell list having at least one cell identifier (ID) and at least one index corresponding to each of the at least one cell ID, and
- control the transceiver to receive a second message including the at least one index corresponding to at least one cell selected from the neighbor cell list based on a predetermined rule via a physical downlink control channel (PDCCH), and
- determine the cell based on the neighbor cell list received in the first message and the at least one index received in the second message.
