## Abstract

The present application provides a wireless communication method. One example method includes: sending, by a first device, a first transport block, where a size of the first transport block is determined based on a product of an initial size of the first transport block and a first parameter, the first parameter is determined based on one or more of the following parameters: a second parameter that indicates channel transmission quality corresponding to the first transport block; or a third parameter that indicates a channel transmission delay corresponding to the first transport block.

## Claims

### Claim 1

A wireless communication method, comprising:
sending, by a first device in a non-terrestrial network, a first transport block, wherein a size of the first transport block is determined based on a multiplication product of an initial size of the first transport block multiplying by a first parameter, the first parameter is determined based on an index of the channel quality indication, wherein the first parameter is set to a first value or a second value, wherein the first parameter is set to the first value if the index of the channel quality indication belongs to a first index range and the first parameter is set to the second value if the index of the channel quality indication belongs to a second index range, wherein each of the first index range and the second index range comprises more than one indices.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the initial size of the first transport block is determined based on one or more of the following:
a quantity of physical resources;
a code rate;
a modulation scheme; or
a quantity of spatial multiplexing layers.

### Claim 3

A wireless communication method, comprising:
receiving, by a second device in a non-terrestrial network, a first transport block, wherein a size of the first transport block is determined based on a multiplication product of an initial size of the first transport block multiplying by a first parameter, the first parameter is determined based on an index of the channel quality indication, wherein the first parameter is set to a first value or a second value, wherein the first parameter is set to the first value if the index of the channel quality indication belongs to a first index range and the first parameter is set to the second value if the index of the channel quality indication belongs to a second index range, wherein each of the first index range and the second index range comprises more than one indices.

### Claim 4

A first device, comprising:
at least one processor;
one or more non-transitory computer-readable storage media coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the apparatus to perform operations comprising:
sending a first transport block, wherein a size of the first transport block is determined based on a multiplication product of an initial size of the first transport block multiplying by a first parameter, the first parameter is determined based on an index of the channel quality indication, wherein the first parameter is set to a first value or a second value, wherein the first parameter is set to the first value if the index of the channel quality indication belongs to a first index range and the first parameter is set to the second value if the index of the channel quality indication belongs to a second index range, wherein each of the first index range and the second index range comprises more than one indices.

### Claim 5 (depends on 4)

The first device according to claim 4, wherein the initial size of the first transport block is determined based on one or more of the following:
a quantity of physical resources;
a code rate;
a modulation scheme; or
a quantity of spatial multiplexing layers.
