Abstract
An information transmission method includes: when a beam failure recovery procedure is initiated for a first cell, initiating random access to a base station through a second cell, wherein the second cell is the first cell or another cell other than the first cell; and if the number of times random access is initiated without being able to complete the random access reaches a preset number, transmitting to the base station indication information for a problem existing in a cell group where the second cell is located, wherein the indication information is used to indicate that the cause for the problem existing in the cell group is the failure of random access caused by the initiation of the beam failure recovery procedure.
