Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method of receiving downlink channel and/or downlink reference signal on an unlicensed band. An LTE user equipment (UE) receives control information of a cell operating on an unlicensed band, and receives downlink channel and/or downlink reference signal transmitted in the cell according to the control information. According to the present disclosure, data can be properly received on an unlicensed band.
Claims28
A method for receiving downlink subframes by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, through a physical downlink control channel (PDCCH) on a cell associated with unlicensed band, indication information on channel occupancy for communication using the unlicensed band, wherein the indication information includes information about orthogonal frequency division multiplexing (OFDM) symbols in a subframe for transmission;
- and
- receiving a signal on at least portion of the OFDM symbols in the subframe for transmission, on the cell associated with unlicensed band based on the indication information,
- wherein configuration of the subframe is related to a downlink pilot time slot (DwPTS) duration of a special subframe, and
- wherein a number of the OFDM symbols in the subframe for transmission is one of a plurality of numbers of OFDM symbols, each of the plurality of numbers of OFDM symbols is defined based on the DwPTS duration of the special subframe.
A user equipment (UE) for receiving downlink subframes in a wireless communication system, the UE comprising:
- a transceiver;
