Buffer status report sending method, terminal device, and network device

An apparatus, comprising:

• a processor, configured to
• determine a first resource, wherein the first resource is a resource configured for a first channel, and the first channel is a data channel, and
• add a first cyclic redundancy check (CRC) to a buffer status report;
• and
• a transceiver, configured to send the first channel and a second channel on the first resource, wherein the second channel is used to carry the buffer status report to which the first CRC is added, wherein before the sending the first channel and the second channel on the first resource, the processor is further configured to add a second CRC to a first transport block, wherein the first channel is used to carry the first transport block to which the second CRC is added, and after the adding the second CRC to the first transport block, the processor is further configured to divide the first transport block to which the second CRC is added into at least two code blocks, and, add a third CRC to each of the at least two code blocks.

An apparatus, comprising:

• a processor, configured to determine a first resource, wherein the first resource is a resource configured for a first channel, and the first channel is a data channel;
• and
• a transceiver, configured to receive a second channel on the first resource, wherein the second channel is used to carry a buffer status report to which a first cyclic redundancy check (CRC) is added, receive the first channel and the second channel on the first resource, wherein the first channel is used to carry a first transport block to which a second CRC is added, wherein the processor is further configured to:
• determine, based on the first CRC, whether the second channel is correctly received, determine, based on the second CRC, whether the first channel is correctly received, wherein the transceiver is configured to:
• receive the first channel and the second channel on the first resource, wherein the first transport block to which the second CRC is added comprises at least two code blocks, and each of the at least two code blocks is a code block to which a third CRC is added.
