1. An information configuration method, applied to a base station, the method comprising:
sending an information reporting request to a terminal working on an unlicensed frequency band, the information reporting request being used to request the terminal to report listen before talk (LBT) information, wherein the number of LBT failures exceeds a preset number;
receiving the LBT information reported by the terminal according to the information reporting request; and
performing parameter configuration on the terminal according to the LBT information,
wherein before the sending an information reporting request to a terminal working on an unlicensed frequency band, the method further comprises:
receiving a notification sent by the terminal that the terminal has stored the LBT information,
wherein the LBT information comprises:
LBT results and location information of LBT; and
location information when the LBT fails; and
location information where the number of LBT failures is greater than a preset number, and
wherein the performing parameter configuration on the terminal according to the LBT information comprises:
determining, according to the LBT information, a target area with an LBT failure probability greater than a preset probability; and
increasing a random access response (RAR) waiting window duration of the target area.
