The invention discloses a method and an apparatus in a node used for wireless communication. The first node sends a first signal; receiving a first signaling in the first resource block; and monitoring the first type of signaling in the first resource block subset by using the spatial parameter of the target reference signal after the first moment. The first signal indicates a first reference signal from M reference signals; a sender of at least one reference signal in the M reference signals is a first cell, and the first cell is not added by the first node; the time domain resource occupied by the first signaling is used for determining the first moment; the sender of the first reference signal is a target cell, and whether the target cell is added by the first node is used for determining whether the target reference signal is the first reference signal. According to the method, rapid cross-cell beam switching is realized, the performance of cell boundary users is improved, and the ping-pong effect is avoided while the service quality is ensured.

The present application discloses a method and apparatus in a node used for wireless communication. A first node receives a first reference signal group; when one of a first condition or a second condition is met, a first signal is sent. The first signal is used to determine a first reference signal; a measurement of the first reference signal group is used to determine whether the first condition and the second condition are met; the first condition includes that the value of the first counter is not less than a first threshold and less than a second threshold, and the second condition includes that the value of the first counter is not less than the second threshold; the first threshold is less than the second threshold; when the first condition is met, the first reference signal belongs to a first reference signal subset; when the second condition is met, the first reference signal belongs to a second reference signal subset. The above method realizes fast cross-cell beam switching, avoiding the ping-pong effect while ensuring the quality of service.
