Buffer state reporting method and terminal equipment

The invention discloses a buffer state reporting method and terminal equipment. When a radio link control (RLC) entity or packet data convergence protocol (PDCP) entity of the terminal equipment has new uplink data to be transmitted and conditions of a regular buffer state report (BSR) and a periodic BSR, a new buffer state report used for indicating the uplink buffer data amount information of the terminal equipment is triggered, or a regular BSR is triggered when the RLC entity or the PDCP entity of the terminal equipment has new uplink data to be transmitted, or the time length of a retransmission BSR timer is set to be less than or equal to a minimum cycle of time division duplex configuration of a time division duplex long term evolution system. According to the improved buffer state reporting method disclosed by the invention, the timeliness and accuracy of uplink data amount obtained by a network side can be raised, thus the network side timely understands the real data amount condition of the terminal equipment, and signaling overload is avoided.
