Claim 14:
15. A method for adjusting automatic retransmission, comprising:
receiving, by a user equipment (UE), adjusted retransmission configuration information delivered from a base station, wherein the UE shares a same original retransmission alternative resource with other UEs for automatic uplink retransmission, and the adjusted retransmission configuration information is used for instructing the UE to adjust a retransmission alternative resource based on the original retransmission alternative resource, wherein the adjusted retransmission configuration information is obtained by adjusting related configuration information of the retransmission alternative resource in response to determining that the original retransmission alternative resource is overloaded,
wherein determining that the original retransmission alternative resource is overloaded comprises:
determining whether an amount of uplink retransmission data currently carried by the original retransmission alternative resource exceeds a preset load threshold value; and
determining that the original retransmission alternative resource is overloaded in response to determining that the amount of the uplink retransmission data is greater than or equal to the preset load threshold value; and
performing, by the UE, uplink retransmission according to the adjusted retransmission configuration information, after listen before talk (LBT) detection performed on a grant-free uplink transmission resource fails.
