Abstract
The present disclosure relates to a communication system, such as a 5G or 6G communication system, capable of supporting higher data transmission rates. Methods and associated devices for transmitting information in a wireless communication system, according to embodiments of the present disclosure, include, but are not limited to, a method for configuring a CQI table, a method for configuring an MCS table, methods for determining related LBRM, PT-RS and system-supported maximum data rates, and a method for determining MCS for retransmission.
Claims12
A method performed by a base station in a wireless communication system, the method comprising:
- identifying at least one transport block size (TBS) value for retransmission, wherein the at least one TBS value is determined based on an amount of resources allocated for retransmission and at least one of modulation and coding scheme (MCS) combinations included in an MCS table and each of the MCS combinations includes a modulation order and a code rate;
- identifying, among the at least one of the MCS combinations, at least one MCS combination that corresponds to a TBS value equal to a TBS value of an initial transmission;
- identifying an MCS index for retransmission among the identified at least one MCS combination based on a sum of buffer occupancies of allocated bearers for a terminal;
- transmitting, to the terminal, control information including the identified MCS index;
- and
- performing a retransmission based on the control information.
A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller coupled to the transceiver and configured to:
- identify at least one transport block size (TBS) value for retransmission, wherein the at least one TBS value is determined based on an amount of resources allocated for retransmission and at least one of modulation and coding scheme (MCS) combinations included in an MCS table and each of the MCS combinations includes a modulation order and a code rate,
- identify, among the at least one of the MCS combinations, at least one MCS combination that corresponds to a TBS value equal to a TBS value of an initial transmission,
- identify an MCS index for retransmission among the identified at least one MCS combination based on a sum of buffer occupancies of allocated bearers for a terminal,
- transmit, to the terminal, control information including the identified MCS index, and
- perform a retransmission based on the control information.
