Abstract
The present invention relates to a wireless communication system, specifically to a method comprising the steps of: configuring a PCell of a licensed band and an SCell of an unlicensed band for a base station; receiving resource configuration information concerning the SCell by means of a physical downlink control channel (PDCCH) of the PCell; configuring a subframe set within a temporary time duration on the SCell on the basis of the resource configuration information; and communicating with the base station by means of the subframe set temporarily configured on the SCell, and to an apparatus for the method.
Claims20
A method for performing communication by a User Equipment (UE) in a cellular communication system, the method comprising:
- receiving resource configuration information about an unlicensed band cell through a Physical Downlink Control Channel (PDCCH);
- receiving reference signals within a contiguous time period of the unlicensed band cell;
- and
- performing a measurement of the reference signals within the contiguous time period of the unlicensed band cell,
- wherein, for the measurement of the reference signals, power per Resource Element (RE) of the reference signals is constant within the contiguous time period of the unlicensed band cell,
- wherein the contiguous time period of the unlicensed band cell comprises a plurality of contiguous Orthogonal Frequency Division Multiplexing (OFDM) symbols, and
- wherein the contiguous time period of the unlicensed band cell is configured based on the resource configuration information.
A User Equipment (UE) for use in a cellular communication system, the UE comprising:
- an radio frequency (RF) module including a transceiver;
- and
- a processor connected to the RF module,
- wherein the processor is configured to:
- receive resource configuration information about an unlicensed band cell through a Physical Downlink Control Channel (PDCCH);
- receive reference signals within a contiguous time period of the unlicensed band cell;
- and
- perform a measurement of the reference signals within the contiguous time period of the unlicensed band cell,
- wherein, for the measurement of the reference signals, power per Resource Element (RE) of the reference signals is constant within a contiguous time period of the unlicensed band cell,
- wherein the contiguous time period of the unlicensed band cell comprises a plurality of contiguous Orthogonal Frequency Division Multiplexing (OFDM) symbols, and
- wherein the contiguous time period of the unlicensed band cell is configured based on the resource configuration information.
A method for performing communication by a Base Station (BS) in a cellular communication system, the method comprising:
- transmitting resource configuration information about an unlicensed band cell through a Physical Downlink Control Channel (PDCCH);
- and
- transmitting reference signals within a contiguous time period of the unlicensed band cell,
- wherein, for a measurement of the unlicensed band cell, power per Resource Element (RE) of the reference signals is constant within the contiguous time period of the unlicensed band cell,
- wherein the contiguous time period of the unlicensed band cell comprises a plurality of contiguous Orthogonal Frequency Division Multiplexing (OFDM) symbols, and
- wherein the contiguous time period of the unlicensed band cell is configured based on the resource configuration information.
A Base Station (BS) for use in a cellular communication system, the BS comprising:
- an radio frequency (RF) module including a transceiver;
- and
- a processor connected to the RF module, wherein the processor is configured to:
- transmit resource configuration information about an unlicensed band cell through a Physical Downlink Control Channel (PDCCH);
- and
- transmit reference signals within a contiguous time period of the unlicensed band cell,
- wherein, for a measurement the unlicensed band cell, power per Resource Element (RE) of the reference signals is constant within the contiguous time period of the unlicensed band cell,
- wherein the contiguous time period of the unlicensed band cell comprises a plurality of contiguous Orthogonal Frequency Division Multiplexing (OFDM) symbols, and
- wherein the contiguous time period of the unlicensed band cell is configured based on the resource configuration information.
