Method and device in nodes used for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first signaling, the first signaling being a Downlink Control Information (DCI) signaling, the first signaling being used to indicate a first symbol set;
• and
• a second transceiver, executing a first radio signal in only a first symbol group in the first symbol set;
• wherein the executing action is receiving, the first radio signal is transmitted on a Physical Uplink Shared CHannel (PUSCH);
• the first radio signal carries a first bit block, the first bit block comprises a transport block (TB);
• wherein the first signaling is used to indicate scheduling information of the first radio signal;
• the first signaling comprises a first field, the first field comprised in the first signaling is used to indicate a first symbol set, and the first field comprised in the first signaling is a Time domain resource assignment field;
• the first symbol set comprises at least one multicarrier symbol, the first symbol group comprises at least one multicarrier symbol, any multicarrier symbol in the first symbol group belongs to the first symbol set, and a number of multicarrier symbol(s) comprised in the first symbol group is not greater than a number of multicarrier symbol(s) comprised in the first symbol set;
• a target Time Division Duplex (TDD) configuration is used to determine a type of each multicarrier symbol in the first symbol set, the target TDD configuration is used to determine the first symbol group out of the first symbol set;
• a given symbol is a multicarrier symbol in the first symbol set;
• when the target TDD configuration is used to determine that a type of the given symbol is a DL symbol, the given symbol does not belong to the first symbol group;
• and the first signaling implicitly indicates the target TDD configuration;
• the phrase of the first signaling implicitly indicating the target TDD configuration comprises:
• the target TDD configuration is associated with a DCI format corresponding to the first signaling, or the target TDD configuration is associated with a transmission scheme of the first radio signal scheduled by the first signaling.
