摘要： The present disclosure provides a method and a device in a communication node for wireless communications. The communication node first receives first information, the first information being used to determine a target time-frequency resource pool; and then monitors a first signaling; after that, when the first signaling is detected, the communication node receives a first radio signal; a first code block is used to generated the first radio signal; 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; whether the first radio signal can be excluded from being used for combined decoding for the first code block is dependent on whether the first time-frequency resource belongs to the target time-frequency resource pool. The present disclosure manages to improve the flexibility of buffer configurations.
