METHOD AND DEVICE FOR USE IN NODES FOR WIRELESS COMMUNICATION

Abstract: a method and device for use in nodes for wireless is provided. one example method includes: transmitting, by a first node, x1 first random access (ra) preambles, x1 being a positive integer greater than 1; monitoring a control signaling for a first random access response (rar) during a first time-window, wherein the first rar corresponds to the x1 first ra preambles; updating a current value of a first counter to obtain an updated value of the first counter when reception of the first rar is not successful while the first time-window expires; and transmitting x2 second ra preambles in response to the updated value of the first counter being less than the first threshold, wherein x2 is a positive integer greater than or equal to x1; or dropping transmission of x2 second ra preambles in response to the updated value of the first counter being greater than the first threshold.
