1. A method comprising:
receiving, by a first access device, first information from a second access device, wherein the first information comprises physical random access channel (PRACH) resource information of uplink (UL) carriers of the second access device, wherein the PRACH resource information of the UL carriers comprises PRACH resource information of a normal uplink carrier and PRACH resource information of a supplementary uplink carrier;
determining, by the first access device, whether there is a conflict between PRACH resource configurations of the first access device and the second access device based on the first information; and
performing, by the first access device, processing based on a determining result of the conflict, wherein the processing comprises using the first information to optimize a random access channel (RACH), or using the first information to coordinate a RACH, or using the first information to reconfigure a RACH.
