摘要： A wireless device (110) receives a frequency resource configuration (200) from an access node (120), the access node generates downlink control information DCI (201) and transmits a control message (202) including at least one slot format indicator, SFI, field and a frequency resource indicator field. Based on the frequency resource indicator, the wireless device determines whether a particular frequency resource is available for operation (203) and whether the wireless device can receive or transmit data on said frequency resource (204, 205).
