AI Technical Summary
In 5G NR systems, the current method of reporting channel quality indicators (CQI) by user equipment (UE) does not accurately consider the repetition transmission number, leading to conservative modulation and coding scheme selections by base stations, which reduces data transmission efficiency due to large quantization errors and limited hybrid automatic repeat request (HARQ) support for ultra-reliable and low-latency communications (URLLC).
The proposed method involves the UE determining CQI based on a target block error ratio (BLER), data repetition transmission number, and channel state information (CSI), with explicit or implicit signaling correction to improve SINR accuracy, allowing for more precise CQI feedback that accounts for repetition transmission, thereby enhancing data transmission efficiency.
This approach improves data transmission efficiency by enabling the base station to make more accurate CQI-based decisions, optimizing modulation and coding schemes, and reducing latency in URLLC communications.
