Abstract
One embodiment of the present invention relates to a method for transmitting a signal to an unlicensed band of a base station in a wireless communication system. The method comprises the steps of: transmitting at least one of a preamble and a reservation signal, if it is determined through carrier sensing that the unlicensed band is available; and transmitting a PDSCH on the unlicensed band immediately after the transmission of at least one of the preamble and the reservation signal. the preamble enables a terminal to acquire reception synchronization for at least one of the reservation signal and the PDSCH.
Claims14
A method of transmitting a signal on an unlicensed band, which is transmitted by an eNode B in a wireless communication system, comprising the steps of:
- transmitting at least one of a preamble or a reservation signal when the unlicensed band is identified as available by a carrier sensing;
- and
- transmitting PDSCH (Physical Downlink Shared CHannel) on the unlicensed band immediately after at least one of the preamble or the reservation signal is transmitted,
- wherein the preamble is configured for a user equipment to acquire reception synchronization of at least one of the reservation signal or the PDSCH.
A method of receiving a signal on an unlicensed band, which is received by a user equipment in a wireless communication system, comprising the steps of:
- receiving at least one of a preamble or a reservation signal from an eNode B on the unlicensed band;
- and
- receiving PDSCH on the unlicensed band,
- wherein the user equipment acquires reception synchronization of at least one of the reservation signal or the PDSCH via the preamble.
An eNode B in a wireless communication system, comprising:
- a transmission module;
- and
- a processor,
- if un unlicensed band is identified as available via a carrier sensing, the processor configured to transmit at least one of a preamble or a reservation signal, the processor configured to transmit PDSCH on the unlicensed band immediately after at least one of the preamble or the reservation signal is transmitted,
- wherein the preamble is configured for a user equipment to acquire reception synchronization of at least one of the reservation signal or the PDSCH.
A user equipment in a wireless communication system, comprising:
- a reception module;
- and
- a processor,
- the processor configured to receive at least one of a preamble or a reservation signal from an eNode B on the unlicensed band, the processor configured to receive PDSCH on the unlicensed band,
- wherein reception synchronization of at least one of the reservation signal or the PDSCH is acquired via the preamble.
