Abstract
In a data transmission method, a terminal device receives control information, and receives data of a transport block (TB); and the terminal devices obtains m code block (CB) groups in the TB, where m is a positive integer, m=min(NCB_re, NGroup_max), NCB_re is a quantity of CBs in the TB, NGroup_max is a maximum value of a quantity of CB groups, each of the m CB groups includes at least one CB, NCB_re is determined based on a TB size (TBS) and a maximum value of a data size of a CB, and the TBS is determined based on the control information.
Claims24
A method, comprising:
- receiving, by a terminal device, control information;
- receiving, by the terminal device based on the control information, data of a transport block (TB);
- and
- obtaining, by the terminal device based on the control information, m code block (CB) groups in the TB, wherein m is a positive integer, m=min(NCB_re, NGroup_max), NCB_re is a quantity of CBs in the TB, NGroup_max is a maximum quantity of CB groups for the TB, each of the m CB groups comprises at least one CB, and NCB_re is determined based on a TB size (TBS) and a maximum size of a CB.
A communication apparatus, comprising:
- a transceiver;
- at least one processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
- cause the transceiver to receive control information, and receive data of a transport block (TB);
- and
- obtain, based on the control information, m code block (CB) groups in the TB, wherein m is a positive integer, m=min(NCB_re, NGroup_max), NCB_re is a quantity of CBs in the TB, NGroup_max is a maximum quantity of CB groups, each of the m CB groups comprises at least one CB, and NCB_re is determined based on a TB size (TBS) and a maximum size of a CB.
A processing apparatus, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to
- decode control information;
- decode, based on the control information, data of a transport block (TB);
- and
- obtain, based on the control information, m code block (CB) groups in the TB, wherein m is a positive integer, m=min(NCB_re, NGroup_max), NCB_re is a quantity of CBs in the TB, NGroup_max is a maximum quantity of CB groups for the TB, each of the m CB groups comprises at least one CB, and NCB_re is determined based on a TB size (TBS) and a maximum size of a CB.
A non-transitory computer-readable storage medium comprising instructions which, when executed by a terminal device, cause the terminal device to perform operations comprising:
- receiving control information;
- receiving, based on the control information, data of a transport block (TB);
- and
- obtaining, based on the control information, m code block (CB) groups in the TB, wherein m is a positive integer, m=min(NCB_re, NGroup_max), NCB_re is a quantity of CBs in the TB, NGroup_max is a maximum quantity of CB groups for the TB, each of the m CB groups comprises at least one CB, and NCB_re is determined based on a TB size (TBS) and a maximum size of a CB.
