Abstract

A method for reporting a buffer state includes: determining a logic channel or logic channel group satisfying a BSR triggering criterion; and if the determined logic channel or logic channel group corresponds to a DRB mapped by an SDAP entity, then reporting to a base station a BSR comprising a buffer of the SDAP entity mapped to the determined logic channel or logic channel group. By determining the logic channel or logic channel group satisfying the BSR triggering criterion and, when the determined logic channel or logic channel group corresponds to the DRB mapped by the SDAP entity, and reporting to the base station the BSR comprising the buffer of the SDAP entity mapped to the determined logic channel or logic channel group, the problem with reporting the buffer state of the logic channel or logic channel group when a new protocol layer is introduced can be solved.
