Claim 14:
15. A communications system, comprising a first access device and a second access device, wherein:
the second access device is configured to:
determine first information, 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; and
send the first information to the first access device; and

the first access device is configured to:
receive the first information from the second access device:
determine 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
perform 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.
