Method and Device in nodes for wireless communication. A first node receives a first configuration information block, a first signaling and a first reference signal resource. The first configuration information block comprises configuration information of the first reference signal resource; the first signaling indicates a first transmission configuration state; the first configuration information block is used to determine a first transmission configuration state set; the first signaling is used to determine a first time; a second transmission configuration state is used to determine a spatial relation of the first reference signal resource before the first time; a spatial relation of the first reference signal resource is related to whether the first transmission configuration state belongs to the first transmission configuration state set after the first time. The above method ensures that when the beam is dynamically updated, a TCI state of a reference signal constantly matches its configuration information.
