Abstract
Disclosed is a method and an apparatus for transmitting/receiving a signal by an MTC UE. The method may include: receiving information on the maximum coverage enhancement level from a base station; determining a coverage enhancement level value for transmitting an uplink signal on the basis of the information on the maximum coverage enhancement level; and repetitively transmitting, a predetermined number of times, the uplink signal according to the coverage enhancement level value.
Claims9
A method for a machine type communication (MTC) user equipment (UE) to transmit and receive a signal, the method comprising:
- receiving, by the MTC UE, information on a cell-specific maximum coverage enhancement level including a value of coverage enhancement level from a base station;
- determining, by the MTC UE, a number of times for transmitting a downlink signal based on the value of the coverage enhancement level;
- repetitively receiving, by the MTC UE, the downlink signal a determined number of times according to the value of the coverage enhancement level, and
- repetitively transmitting, by the MTC UE, the uplink signal a number of times,
- wherein the downlink signal is a downlink common control channel or common control message, and
- wherein the information on the cell-specific maximum coverage enhancement level is transmitted through a physical broadcast channel (PBCH) or a system information block (SIB) for the MTC UE, and the downlink common control message comprises one of the system information blocks (SIBs), a random access response (RAR), and a paging message.
A method for a base station to transmit and receive a signal, the method comprising:
- transmitting, by the base station, information on cell-specific maximum coverage enhancement level including a value of coverage enhancement level to a machine type communication (MTC) user equipment (UE);
- and
- repetitively transmitting, by the base station, a downlink signal a determined number of times according to the value of the coverage enhancement level to the MTC UE;
- repetitively receiving, by the base station, an uplink signal a number of times,
- wherein the information on the cell-specific maximum coverage enhancement level is transmitted through a physical broadcast channel (PBCH) or system information blocks (SIBs) for the MTC UE, and the downlink common control message comprises one of the system information (SIB), a random access response (RAR)(, and a paging message.
A machine type communication (MTC) user equipment (UE) to transmit and receive a signal, the MTC UE comprising:
- a receiving unit configured to receive information on cell-specific maximum coverage enhancement level including a value of coverage enhancement level from a base station;
- a controller configured to determine a number of times for transmitting a downlink signal based on the value of the coverage enhancement level of the information on the cell-specific maximum coverage enhancement level;
- and
- a transmitting unit configured to repetitively transmit the downlink signal a determined number of times according to the value of the coverage enhancement level and repetitively transmit the uplink signal a number of times,
- wherein the downlink signal is a downlink common control channel or common control message, and
- wherein the information on the cell-specific maximum coverage enhancement level is transmitted through a physical broadcast channel (PBCH) or a system information block (SIB) for the MTC UE, and the downlink common control message comprises one of the system information blocks (SIBs), a random access response (RAR), and a paging message.
