Method and device in communication nodes for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first signaling;
• wherein the first signaling is used to indicate occupancy of a first time-frequency resource set, the first time-frequency resource set comprising multiple resource units;
• the occupancy of the first time-frequency resource set is used by a receiver of the first signaling to determine a target threshold;
• the occupancy of the first time-frequency resource set comprises at least one of whether the first time-frequency resource set is occupied or a type of a signal occupying the first time-frequency resource set;
• the first time-frequency resource set is associated with a second time-frequency resource set, the second time-frequency resource set comprising multiple resource units;
• the target threshold is used by a receiver of the first signaling to determine whether the second time-frequency resource set belongs to the first candidate resource pool.

A method in a first node for wireless communications, comprising:

• receiving a first signaling;
• and
• transmitting a target positioning reference signal on a target time-frequency resource set, the target time-frequency resource set comprising multiple resource units;
• wherein the first signaling is used to indicate occupancy of a first time-frequency resource set, the first time-frequency resource set comprising multiple resource units;
• parameters of the target positioning reference signal and the occupancy of the first time-frequency resource set are jointly used to determine a target threshold;
• the occupancy of the first time-frequency resource set comprises at least one of whether the first time-frequency resource set is occupied or a type of a signal occupying the first time-frequency resource set;
• the target time-frequency resource set belongs to a first candidate resource pool, and the first time-frequency resource set is associated with a second time-frequency resource set, the second time-frequency resource set comprising multiple resource units;
• the target threshold is used to determine whether the second time-frequency resource set belongs to the first candidate resource pool.
