Method and device for HARQ transmissions in communication nodes for wireless communication

A first-type communication node for wireless communications, comprising:

• a first transceiver, which receives first information, the first information being used to determine a target time-frequency resource pool;
• a second transceiver, which monitors a first signaling;
• and
• a first receiver, which receives a first radio signal when the first signaling is detected;
• wherein a first code block is used to generate the first radio signal, and the first code block comprises a positive integer number of bit(s);
• time-frequency resources occupied by the first signaling comprise a first time-frequency resource, while time-frequency resources occupied by the first radio signal comprise a second time-frequency resource;
• when channel decoding of the first radio signal is failed, whether a HARQ for the first radio signal can be switched off is dependent on whether the first time-frequency resource belongs to the target time-frequency resource pool, or whether the HARQ for the first radio signal can be switched off is dependent on whether the second time-frequency resource belongs to the target time-frequency resource pool;
• the first information and the first signaling are transmitted via an air interface.

A second-type communication node for wireless communications, comprising:

• a third transceiver, which transmits first information, the first information being used to determine a target time-frequency resource pool;
• a fourth transceiver, which transmits a first signaling;
• and
• a first transmitter, which transmits a first radio signal;
• wherein a first code block is used to generate the first radio signal, and the first code block comprises a positive integer number of bit(s);
• time-frequency resources occupied by the first signaling comprise a first time-frequency resource, while time-frequency resources occupied by the first radio signal comprise a second time-frequency resource;
• when channel decoding of the first radio signal is failed, whether a HARQ for the first radio signal can be switched off is dependent on whether the first time-frequency resource belongs to the target time-frequency resource pool, or whether the HARQ for the first radio signal can be switched off is dependent on whether the second time-frequency resource belongs to the target time-frequency resource pool;
• the first information and the first signaling are transmitted via an air interface.
