Classification: CPC H | IPC H

Claim 2:
3. A base station, comprising:
a processor; and
a memory for storing processor executable instructions,
where the processor is configured to:
send 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;
receive the LBT information reported by the terminal according to the information reporting request; and
perform parameter configuration on the terminal according to the LBT information,
wherein the processor is further configured to:
receive a notification sent by the terminal that the terminal has stored the LBT information, before the sending an information reporting request to a terminal working on an unlicensed frequency band,
wherein the LBT information comprises:
LBT results and location information of LBT;
location information when the LBT fails; and
location information where the number of LBT failures is greater than a preset number, and
wherein the parameter configuration performed by the processor is further configured to:
determine, according to the LBT information, a target area with an LBT failure probability greater than a preset probability; and
increase a random access response (RAR) waiting window duration of the target area.
