AI Technical Summary
Technical Problem
In flexible duplex mode, it is difficult for UE to effectively control power during random access, resulting in a decrease in access success rate and an increase in transmission delay.
Method used
By receiving the information block of TDD up-down link configuration indication, the UE adjusts the transmission power of the first signal according to the target received power and the path loss of the reference signal, and determines the target step size using the symbol type among the multiple candidate step sizes to optimize power control.
Benefits of technology
Improves the success rate of random access and transmission reliability, reduces transmission delay and reduces hardware complexity and cost.

Abstract
The invention discloses a method and an apparatus in a node used for wireless communication. A node receives a first information block on which a symbol type of at least one symbol indicated as a downlink by a TDD uplink and downlink configuration depends; a node sends a first signal, the transmitting power of which depends on the target receiving power of the first signal and the path loss of a reference signal associated with the first signal; the power raising value of the target receiving power depends on a target step length, the target step length is one of a plurality of candidate step lengths, and any one of the plurality of candidate step lengths is an integer; the symbol type of at least one symbol overlapped by the first signal in the time domain is used for determining the target step size from the plurality of candidate step sizes. According to the invention, the random access time delay is reduced.
