The present disclosure provides a method and device in User Equipment (UE) and a base station for dynamic scheduling. The UE first receives first information; and then receives second information; and operates a first radio signal. Wherein the first information comprises Q field(s), a first field is used to determine a first antenna port set, the first field is one field of the Q field(s). The first antenna port set comprises a positive integer of antenna port(s), the second information is transmitted by an antenna port within the first antenna port set. The first information and the second information are both dynamically configured. The operating refers to receiving, or the operating refers to transmitting. The second information is used to determine scheduling information of the first radio signal. The present disclosure ensures the robustness of scheduling signaling reception in multi-antenna scenarios, and also avoids excessive overhead, hence improving transmission efficiency.
