Channel Coding Method, Data Receiving Method, and Related Device

A method, comprising:

• receiving, by a device, second indication information indicating redundancy versions for at least N transmissions of a transport block (TB), wherein a time unit of each transmission of the at least N transmissions is a basic transmission time unit of N basic transmission time units, wherein the redundancy versions for the at least N transmissions are different, and wherein N is an integer greater than 1;
• and
• receiving, by the device, target data from a sending device, wherein the target data is obtained by mapping all or part of one or more bit sequences Sj to transmission resources of the N basic transmission time units, wherein j is a numeric sequence of integers from 1 to k, wherein where Sj belongs to a set S, S={S1, S2 . . . Sk}, wherein a bit sequence of the one or more bit sequences Sj is a bit sequence obtained after dividing the TB into k code blocks (CBs) and performing channel coding on one code block of the k CBs, wherein the TB includes a cyclic redundancy check bit, wherein all or part of the one or more bit sequences Sj is mapped to transmission resources of a subset or a universal set of the N basic transmission time units, and wherein a start position in the transmission resources of the N basic transmission time units for the one or more bit sequences Sj is determined based on redundancy versions for the at least N transmissions of the TB.

A device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• sending, by a device, second indication information indicating redundancy versions for at least N transmissions of a transport block (TB), wherein a time unit of each transmission of the at least N transmissions is a basic transmission time unit of N basic transmission time units, wherein the redundancy versions for the at least N transmissions are different, and wherein N is an integer greater than 1;
• including, by the device, a cyclic redundancy check bit into the TB;
• dividing, by the device, the TB into k code blocks (CBs), wherein k is an integer greater than or equal to 1;
• separately performing, by the device, channel coding on the k CBs to obtain one or more bit sequences Sj, wherein j is a numeric sequence of integers from 1 to k, where Sj belongs to a set S, S={S1, S2 . . . Sk};
• and
• mapping, by the device, all or part of the one or more bit sequences Sj to transmission resources of a subset, or a universal set, of the N basic transmission time units, wherein a start position in the transmission resources of the N basic transmission time units for the one or more bit sequences Sj is determined based on redundancy versions for the at least N transmissions of the TB.
