Abstract
Methods and apparatuses for HARQ in a non-terrestrial network are disclosed. An operation method of a first node may comprise receiving a transport block (TB) from a second node; classifying total soft bits for the TB into information values and sign values; configuring the information values of the total soft bits into one or more subsets; performing a compression operation on each of the one or more subsets; and performing a compression operation on the sign values. Therefore, performance of the communication system can be improved.

An operation method of a first node in a communication network, the operation method comprising:
- receiving, by a processor included in the first node, a transport block (TB) from a second node;
- classifying, by the processor, total soft bits for the TB into information values and sign values;
- configuring, by the processor, the information values of the total soft bits into one or more subsets;
- performing, by the processor, a compression operation on each of the one or more subsets;
- and
- performing, by the processor, a compression operation on the sign values,
- wherein the each of the one or more subsets includes a part of the information values.
An operation method of a first node in a communication network, the operation method comprising:
- receiving, by a processor included in the first node, a first transport block (TB) and a second TB from a second node;
- configuring, by the processor, first information values included in first soft bits for the first TB into one or more first subsets;
- generating, by the processor first intra sequences by performing a transform coding operation on each of the one or more first subsets;
- configuring, by the processor, second information values included in second soft bits for the second TB into one or more second subsets;
- generating, by the processor, second intra sequences by performing the transform coding operation on each of the one or more second subsets;
- generating, by the processor, one hybrid automatic repeat request (HARQ) sequence including a first inter sequence consisting of the first intra sequences and a second inter sequence consisting of the second intra sequences;
- and
- generating, by the processor, compressed information values by performing an encoding operation on the one HARQ sequence,
- wherein the each of the one or more first subsets includes a part of the first information values and the each of the one or more second subsets includes a part of the second information. values.
A first node in a communication network, the first node comprising a processor and a memory storing at least one instruction executable by the processor, wherein when executed by the processor, the at least one instruction configures the processor to:
- receive a transport block (TB) from a second node;
- classify total soft bits for the TB into information values and sign values;
- configure the information values of the total soft bits into one or more subsets;
- perform a compression operation on each of the one or more subsets;
- and
- perform a compression operation on the sign values,
- wherein the each of the one or more subsets includes a part of the information values.
