<p>Disclosed is a method for triggering a buffer status report (BSR). The method comprises: a user apparatus sending to a base station a transport block (TB) carrying a BSR; according to hybrid automatic repeat request (HARQ) feedback information returned by the base station and indicating whether the TB is successfully received, determining whether a HARQ failure occurs to the sent TB; when it is determined that the HARQ failure occurs to the sent TB, triggering a conventional BSR. Also disclosed are a device and a user apparatus for triggering a BSR. By using the method, device and user apparatus of the present invention, when a TB sent by a user apparatus and comprising a BSR fails to be received by a base station correctly, a user can be informed in advance that the sent BSR is not correctly received by the base station, so as to trigger a new conventional BSR in a timely and rapid fashion, thereby shortening an undesirable waiting time, preventing the phenomenon of frequent interruption in uplink transmission of the user apparatus, and greatly improving the efficiency of the uplink transmission of the user apparatus.</p> |
