Abstract

Embodiments of the present application provide a method and device for configuring a codebook feedback mode, a base station device and a storage medium. The method for configuring the codebook feedback mode comprises: periodically counting a scheduling traffic during a carrier aggregation service process to obtain a scheduling traffic counting result; determining a scheduling condition according to the scheduling traffic counting result; and configuring a target codebook feedback mode according to the scheduling condition. Embodiments of the present application periodically count the scheduling traffic during the carrier aggregation service process, dynamically modify the codebook feedback mode according to the scheduling condition, realize real-time switching of dynamic HARQ codebook and semi-static HARQ codebook feedback modes, and achieve the purpose of using the semi-static codebook to save scheduling time and reduce control processes when scheduling is intensive, and using the dynamic codebook to save resources when scheduling is sparse.
