Abstract
Provided are a communication method and an apparatus utilizing the same in a wireless communication system. The apparatus configures a resource reservation period (RRP), the period during which channel access by the apparatus permitted in an unlicensed band is not permitted. When the permission conditions are met, the apparatus accesses the channel during the RRP.
Claims10
A method for communicating in a wireless communication system, the method performed by a wireless device and comprising:
- setting up a resource reservation period (RRP) which is a period during which channel access by the wireless device is not permitted in an unlicensed band;
- and
- performing channel access during the RRP if a permission condition is satisfied,
- wherein a first clear channel assessment (CCA) threshold in the unlicensed band during the RRP is greater than a second CCA threshold outside the RRP,
- wherein signals by other wireless devices are not transmitted during the RRP based on the first CCA threshold,
- wherein the channel access is not performed outside the RRP, and
- wherein signals by other wireless devices are transmitted outside the RRP based on the second CCA threshold.

An apparatus for communicating in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the transceiver and configured to:
- set up a resource reservation period (RRP) during which channel access by the apparatus is not permitted in an unlicensed band;
- and
- control the transceiver to perform the channel access during the RRP if a permission condition is satisfied,
- wherein a first clear channel assessment (CCA) threshold in the unlicensed band during the RRP is greater than a second CCA threshold outside the RRP,
- wherein signals by other wireless devices are not transmitted during the RRP based on the first CCA threshold,
- wherein the channel access is not performed outside the RRP, and
- wherein signals by other wireless devices are transmitted outside the RRP based on the second CCA threshold.
