Zusammenfassung:The invention provides the method and apparatus for node and UE to schedule and transmit CTS in a communication network. The method comprises that a node transmits a RTS for indicating a CTS scheduling information to a LTE in an unlicensed band, wherein the scheduling information is used to indicate the LTE to send a CTS in uplink licensed band in response to the RTS. The CTS scheduling information may explicitly include time resource and frequency resource for the UE to transmit the CTS. The CTS scheduling information may implicitly indicate the time and frequency resource for the UE to transmit the CTS. Based on the explicit or implicit schemes of the present application, the scheduling signaling overhead can be reduced and the co-existence problem between LTE-U/LTE-U or between LTE-U/Wi-Fi can be efficiently mitigated.
