Abstract: A buffer status report sending method and a communication apparatus are provided. The buffer status report sending method includes: receiving a first configuration message from an access network device, where the first configuration message is used to configure a one-to-one correspondence between a plurality of buffer status BS intervals and a plurality of index values; and sending a buffer status report BSR to the access network device based on the correspondence, where the BSR includes a target index value, and the plurality of index values include the target index value. According to the BSR sending method, a terminal may send the BSR to the access network device based on the correspondence that is between the BS interval and the index value and that is configured by the access network device for the terminal, to request a transmission resource that better meets an actual requirement of the terminal.

Abstract: A data transmission method and a data transmission apparatus are provided, to help reduce a transmission delay of a service frame. The method includes: A terminal sends first indication information to a network device. The first indication information indicates a statistical parameter of a delay jitter of an arrival time of a service frame. The statistical parameter of the delay jitter is for determining a CG resource. The network device sends second indication information to the terminal. The second indication information indicates the CG resource. The CG resource is determined based on the first indication information. The terminal and the network device communicate the service frame based on the CG resource.
