Abstract
Provided are a method for communicating in a wireless communication system and a device using the same. A wireless device receives a switching command instructing the switching between a clear channel assessment (CCA) operation and a non-CCA operation in an unlicensed band. According to the switching command, the wireless device performs the CCA operation or the non-CCA operation in the unlicensed band.
Claims7
A method for communicating in a wireless communication system, the method comprising:
- receiving, by a wireless device, a switching command for instructing a switching between a clear channel assessment (CCA) operation and a non-CCA operation in an unlicensed band,
- wherein the switching command is received by detecting a physical downlink control channel (PDCCH) having a cyclic redundancy check (CRC) scrambled by a dedicated identifier, and
- wherein the dedicated identifier is a switching-radio network temporary identifier (S-RNTI) indicating the switching command;
- and
- performing, by the wireless device, the CCA operation or the non-CCA operation in the unlicensed band according to the switching command.

A device in a wireless communication system, the device comprising:
- a radio frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the RF unit and configured to:
- control the RF unit to receive a switching command for instructing a switching between a clear channel assessment (CCA) operation and a non-CCA operation in an unlicensed band,
- wherein the switching command is received by detecting a physical downlink control channel (PDCCH) having a cyclic redundancy check (CRC) scrambled by a dedicated identifier, and
- wherein the dedicated identifier is a switching-radio network temporary identifier (S-RNTI) indicating the switching command;
- and
- control the RF unit to perform the CCA operation or the non-CCA operation in the unlicensed band according to the switching command.
