1. A first device comprising:
at least one processor; and
at least one memory including computer program codes;
the at least one memory and the computer program codes are configured to, with the at least one processor, cause the first device at least to:
determine a channel occupancy time structure for accessing a radio channel between the first device and a second device, the channel occupancy time structure indicating a set of time-domain resources for accessing the radio channel;
receive, from the second device, an indication of the following: a first reference value of the timing advance relating to a compensation period for a delay of the transmission and a switching period for the second device to switch from a receiving mode to a transmitting mode; a second reference value of the timing advance relating to the compensation period and a sensing time period for a LBT procedure; and a third reference value of the timing advance relating to the sensing time period;
determine that the channel occupancy time structure is unascertainable; and
based on a determination that the channel occupancy time structure is unascertainable, set a timing advance to the third reference value for a transmission from the first device to the second device.
