Abstract
The invention discloses a method and an apparatus in a communication node used for wireless communication. When the first counter reaches a first value, initiating a first random access process, and sending a first signal; when the first random access process is not successfully completed, updating a second counter; as a response that each condition in the first condition set is satisfied, generating a second type of indication and transmitting the second type of indication to an upper layer; the first counter indicates the number of times of receiving a first type of indication from a lower layer; the first signal is used for random access; the second counter indicates the sending times of the lead code sequence; one condition in the first condition set is that the second counter reaches a second numerical value; the first value is a positive integer; the second value is a positive integer. The invention provides an inter-cell beam operation method for beam-based communication, and the probability of failure of triggering a wireless link of an RRC layer is reduced.
