Data transmission method and communication device

A communication device, comprising:

• a processor, a transceiver, and a memory;
• wherein the processor is configured to execute instructions stored by the memory;
• wherein when the processor executes the instructions stored in the memory, the communication device is caused to:
• obtain transmission parameters for transmitting a transport block, wherein the transmission parameters comprise Modulation and Coding Scheme (MCS), a Physical Resource Block (PRB) number, and PRB resource overhead information;
• determine a Transport Block Size (TBS) for the transport block according to the transmission parameters;
• and
• transmit the transport block or receive the transport block according to the TBS;
• wherein the PRB resource overhead information is determined based on at least one of:
• Demodulation Reference Signal (DMRS), Channel State Information-Reference Signals (CSI-RS), and control channel information.

A chip, comprising:

• an input interface, an output interface, and a processor, wherein the processor is configured to:
• obtain transmission parameters for transmitting a transport block, wherein the transmission parameters comprise Modulation and Coding Scheme (MCS), a Physical Resource Block (PRB) number, and PRB resource overhead information;
• determine a Transport Block Size (TBS) for the transport block according to the transmission parameters;
• and
• instruct a transceiver to transmit the transport block or receive the transport block according to the TBS;
• wherein the PRB resource overhead information is determined based on at least one of:
• Demodulation Reference Signal (DMRS), Channel State Information-Reference Signals (CSI-RS), and control channel information.
