Abstract
Example methods and apparatus for determining a transport block size are described. One example method includes determining a transport block size (TBS) of a first transport block by a communications apparatus. The communications apparatus determines a TBS of a second transport block based on the TBS of the first transport block, where the first transport block is different from the second transport block, the TBS of the second transport block is equal to the TBS of the first transport block, and a data channel carrying the first transport block and a data channel carrying the second transport block occupy a same time domain resource.
Claims20
A method for determining a transport block size, wherein the method comprises:
- determining, by a communications apparatus, a transport block size (TBS) of a first transport block;
- and
- determining, by the communications apparatus, a TBS of a second transport block based on the TBS of the first transport block, wherein the first transport block is different from the second transport block, the TBS of the second transport block is equal to the TBS of the first transport block, and a data channel carrying the first transport block and a data channel carrying the second transport block occupy a same time domain resource, wherein an index value of a transmission configuration indication state (TCI) state associated with the data channel carrying the first transport block is smaller than an index value of a TCI state associated with the data channel carrying the second transport block, and wherein a quantity of time-frequency elements corresponding to the first transport block is larger than a quantity of time-frequency elements corresponding to the second transport block;
- wherein when the communications apparatus includes a first terminal, the first transport block is received from a first network device and the second transport block is received from a second network device;
- and
- wherein when the communications apparatus includes a first network device, the first transport block and the second transport block are transport blocks to be sent to a second terminal.
A communications apparatus, comprising:
- at least one processor, and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
- determining a transport block size (TBS) of a first transport block;
- and
- determining a TBS of a second transport block based on the TBS of the first transport block, wherein the first transport block is different from the second transport block, the TBS of the second transport block is equal to the TBS of the first transport block, and a data channel carrying the first transport block and a data channel carrying the second transport block occupy a same time domain resource, wherein an index value of a transmission configuration indication state (TCI) state associated with the data channel carrying the first transport block is smaller than an index value of a TCI state associated with the data channel carrying the second transport block, and wherein a quantity of time-frequency elements corresponding to the first transport block is larger than a quantity of time-frequency elements corresponding to the second transport block;
- wherein when the communications apparatus includes a first terminal, the first transport block is received from a first network device and the second transport block is received from a second network device;
- and
- wherein when the communications apparatus includes a first network device, the first transport block and the second transport block are transport blocks to be sent to a second terminal.
A communications system, comprising a plurality of network devices, wherein the plurality of network devices comprise a first network device and a second network device, and the second network device is different from the first network device, and wherein:
- the first network device is configured to:
- determine a transport block size (TBS) of a first transport block;
- and
- send a notification message to the second network device, wherein the notification message is used to indicate the TBS of the first transport block;
- and
- the second network device is configured to:
- receive the notification message;
- and
- determine a TBS of a second transport block based on the TBS of the first transport block, wherein the first transport block is different from the second transport block, the TBS of the second transport block is equal to the TBS of the first transport block, and a data channel carrying the first transport block and a data channel carrying the second transport block occupy a same time domain resource, wherein an index value of a transmission configuration indication state (TCI) state associated with the data channel carrying the first transport block is smaller than an index value of a TCI state associated with the data channel carrying the second transport block, and wherein a quantity of time-frequency elements corresponding to the first transport block is larger than a quantity of time-frequency elements corresponding to the second transport block;
- and
- the first transport block and the second transport block are transport blocks to be sent to a terminal.
