Abstract
The present invention relates to a method and an apparatus for a base station transmitting a downlink signal for a machine-type communication (MTC) terminal. More specifically, the present invention relates to a method for transmitting and receiving PBCH, PRACH, PDSCH, PDCCH or EPDCCH for a low cost and enhanced coverage MTC terminal, and an apparatus therefor. Particularly, provided are an apparatus and a method for a base station transmitting a control channel, the method comprising the steps of repeatedly transmitting a control channel comprising control information, and repeatedly transmitting downlink data channel (PDSCH) on the basis of information for a subframe ending the control channel being repeatedly transmitted.
Claims15
A method of receiving a downlink channel by a user equipment in enhanced coverage, the method comprising:
- receiving, for one or more repetitions in a time domain, by the user equipment from a base station, a physical downlink control channel including control information;
- and
- receiving, for one or more repetitions in the time domain, by the user equipment from the base station, a physical downlink shared channel,
- wherein the control information includes downlink scheduling information related to the physical downlink shared channel that is transmitted based on a repetition level of multiple repetition levels, and
- wherein the multiple repetition levels for the physical downlink shared channel are specified in the time domain.
A base station for transmitting a downlink channel to a user equipment in enhanced coverage, the base station comprising:
- a transmitting unit for transmitting the downlink channel;
- a receiving unit for receiving an uplink channel;
- and
- a control unit for controlling the transmitting unit and the receiving unit,
- wherein the control unit is configured to:
- control the transmitting unit to transmit, for one or more repetitions in a time domain, to the user equipment, a physical downlink control channel including control information;
- and
- control the transmitting unit to transmit, for one or more repetitions in the time domain, to the user equipment, a physical downlink shared channel,
- wherein the control information includes downlink scheduling information related to the physical downlink shared channel that is transmitted based on a repetition level of multiple repetition levels, and
- wherein the multiple repetition levels for the physical downlink shared channel are specified in the time domain.
A user equipment for receiving a downlink channel in enhanced coverage, the user equipment comprising:
- a transmitting unit for transmitting an uplink channel;
- a receiving unit for receiving the downlink channel;
- and
- a control unit for controlling the transmitting unit and the receiving unit,
- wherein the control unit is configured to:
- control the receiving unit to receive, for one or more repetitions in a time domain, from a base station, a physical downlink control channel including control information, and
- control the receiving unit to receive, for one or more repetitions in the time domain, from the base station, a physical downlink shared channel,
- wherein the control information includes downlink scheduling information related to the physical downlink shared channel that is transmitted based on a repetition level of multiple repetition levels, and
- wherein the multiple repetition levels for the physical downlink shared channel are specified in the time domain.
