Abstract
An operation method of a first communication node in a communication system includes receiving one or more transport blocks (TBs) from a second communication node based on transmission parameters in an aggregated transmission period #n; generating decoding results for the one or more TBs; generating information required for changing the transmission parameters based on the decoding results; and transmitting the required information to the second communication node, wherein n is a natural number.
Claims14
An operation method of a first communication node in a communication system, the operation method comprising:
- receiving a plurality of transport blocks (TBs) including a same data unit #1 from a second communication node based on transmission parameters in an aggregated transmission period #n including a plurality of slots;
- generating decoding results for the plurality of TBs;
- generating information required for changing the transmission parameters based on the decoding results;
- and
- transmitting the required information to the second communication node,
- wherein the required information includes statistical information on the decoding results, the statistical information of the aggregated transmission period #n is used for determining an effective code rate applied to an aggregated transmission period #n+k including one or more slots after the aggregated transmission period #n, one or more TBs including a same data unit #2 which is different from the same data unit #1 are received in the aggregated transmission period #n+k, each of the aggregated transmission periods #n and #n+k is used for repeated transmission of a TB including a same data unit, and each of n and k is a natural number.
An operation method of a second communication node in a communication system, the operation method comprising:
- transmitting transmission parameters to a first communication node;
- transmitting a plurality of transport blocks (TBs) including a same data unit #1 to the first communication node based on the transmission parameters in an aggregated transmission period #n including a plurality of slots;
- receiving information required for changing the transmission parameters from the first communication node;
- changing the transmission parameters in consideration of the required information;
- and
- transmitting the changed transmission parameters to the first communication node,
- wherein the required information includes statistical information on decoding results in the aggregated transmission period #n, the statistical information of the aggregated transmission period #n is used for determining an effective code rate applied to an aggregated transmission period #n+k including one or more slots after the aggregated transmission period #n, one or more TBs including a same data unit #2 which is different from the same data unit #1 are transmitted in the aggregated transmission period #n+k, each of the aggregated transmission periods #n and #n+k is used for repeated transmission of a TB including a same data unit, and each of n and k is a natural number.
