Abstract
A communication method and an apparatus are provided. When a cell served by a distributed unit (DU) of an access network device and a neighboring cell use different timing, the DU may obtain timing configurations of a first cell and a second cell, or a random access channel (RACH) configuration that is of a second cell and that is based on timing of a first cell. When the method is applied to a RACH optimization scenario, the DU may determine, at same timing, RACH configurations of the two cells based on the foregoing obtained information, to accurately identify whether a RACH configuration conflict occurs between the cell and the neighboring cell, optimize the RACH configuration of the cell when the conflict occurs, and ensure a success rate and an access latency of random access performed by a terminal device.
