Method and device in nodes used for wireless communication

A second node for wireless communications, comprising:

• a first transmitter, transmitting a first signaling, the first signaling being used to determine a first time-frequency resource;
• and
• a second transceiver, executing a first signal in the first time-frequency resource;
• wherein the first signaling is identified by a target RNTI;
• whether the target RNTI is used for scrambling of the first signal is related to a type of the target RNTI;
• the executing action is transmitting, or the executing action is receiving;
• the type of the target RNTI belongs to one of a first type set and a second type set;
• when the type of the target RNTI belongs to the first type set, the target RNTI is used for scrambling of the first signal, and when the type of the target RNTI belongs to the second type set, the target RNTI is not used for scrambling of the first signal;
• only the first type set in the first type set and the second type set comprises a C-RNTI;
• there does not exist an RNTI type belonging to the first type set and the second type set at the same time.

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

• receiving a first signaling, the first signaling being used to determine a first time-frequency resource;
• and
• operating a first signal in the first time-frequency resource;
• wherein the first signaling is identified by a target RNTI;
• whether the target RNTI is used for scrambling of the first signal is related to a type of the target RNTI;
• the operating action is receiving, or, the operating action is transmitting;
• the type of the target RNTI belongs to one of a first type set and a second type set;
• when the type of the target RNTI belongs to the first type set, the target RNTI is used for scrambling of the first signal, and when the type of the target RNTI belongs to the second type set, the target RNTI is not used for scrambling of the first signal;
• only the first type set in the first type set and the second type set comprises a C-RNTI;
• there does not exist an RNTI type belonging to the first type set and the second type set at the same time.
