Method and apparatus for link adaptation in wireless communication system

A base station comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• and
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the base station to:
• transmit first ultra-reliable low-latency communications (URLLC) data to a user equipment (UE), based on a first time resource and a first frequency resource,
• transmit a padding signal to the UE, based on a second time resource and the first frequency resource,
• receive a first hybrid automatic repeat request (HARQ) signal for the padding signal from the UE,
• generate a block error rate (BLER) value,
• generate a correction constant for a signal-to-interference-plus-noise ratio (SINR), based on the BLER value,
• correct an outer loop rate control (OLRC) offset, based on the first HARQ signal,
• correct the SINR, based on the corrected OLRC offset and the correction constant, and
• based on a modulation and coding scheme (MCS) determined based on the corrected SINR, transmit second URLLC data to the UE, based on a third time resource and the first frequency resource.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of a base station in a wireless communication system individually or collectively, cause the base station to perform operations, the operations comprising:

• transmitting, by the base station, first ultra-reliable low-latency communications (URLLC) data to a user equipment (UE), based on a first time resource and a first frequency resource;
• transmitting, by the base station, a padding signal to the UE, based on a second time resource and the first frequency resource;
• receiving, by the base station, a first hybrid automatic repeat request (HARQ) signal for the padding signal from the UE;
• generating, by the base station, a block error rate (BLER) value;
• generating, by the base station, a correction constant for a signal-to-interference-plus-noise ratio (SINR), based on the BLER value;
• correcting, by the base station, an outer loop rate control (OLRC) offset, based on the first HARQ signal;
• correcting, by the base station, the SINR, based on the corrected OLRC offset and the correction constant;
• and
• based on a modulation and coding scheme (MCS) determined based on corrected SINR, transmitting, by the base station, second URLLC data to the UE, based on a third time resource and the first frequency resource.
