Method and device in nodes used for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first signaling and a second signaling;
• the first signaling being used to determine a first time-domain resource set, the second signaling being used to determine a second time-domain resource set;
• and
• a second receiver, receiving a first signal in a first time-domain resource subset, and receiving a second signal in a second time-domain resource subset;
• wherein the first time-domain resource set comprises the first time-domain resource subset and the second time-domain resource subset;
• the second time-domain resource set comprises the first time-domain resource subset and the second time-domain resource subset, and the first time-domain resource subset is orthogonal to the second time-domain resource subset in time domain;
• the first time-domain resource set is reserved for transmitting a first bit set;
• the first bit set is used to generate the first signal;
• the first bit set is used to generate the second signal, the second signaling is used to schedule a second bit block, the first time-domain resource subset is associated with a first reference signal resource, and the second signaling is used to indicate a second reference signal resource;
• whether the first reference signal resource and the second reference signal resource are Quasi Co-Located (QCL) is used to determine whether the second bit block is used to generate the second signal.
