Transmission control method and device of buffer state report (BSR)

The invention discloses a transmission control method and a transmission control device of buffer state report (BSR), wherein the method and device are used for adjusting physical resources which transmit BSR to increase transmission chances of the BSR, so that the transmission success rate of the BSR is improved. The transmission control method of BSR comprises the steps of: distributing a physical uplink shared channel (PUSCH) resource for a terminal when a schedule requirement (SR) transmitted by the terminal is received, and sending a UL-GRANT which carries a PUSCH resource indication distributed for the terminal to the terminal; detecting a decoding result of BSR transmitted by the terminal via the PUSCH resource; judging whether the sending of the UL-GRANT is continued or not, and adjusting PUSCH resource positions distributed for the terminal.
