| 发明名称 | Method and device for retransmitting data under antenna gain imbalance | ||
| 摘要 | The disclosure provides a method and device for retransmitting data under antenna gain imbalance, and the method includes: determining that gains of multiple antennas at a transmission terminal are imbalanced; using a better spatial sub-channel in the multiple antennas to retransmit data when streams transmitted by the multiple antennas adopt a same Modulation and Coding Scheme; and using a better spatial sub-channel in the multiple antennas to retransmit data and/or using a single-stream approach to retransmit data when the streams transmitted by the multiple antennas adopt different Modulation and Coding Schemes. The disclosure selects a corresponding retransmission approach according to the condition of a spatial sub-channel on which streams have an error, thus improving and ensuring success rate for retransmitting a stream. | ||

| 主权项 | 1. A method for retransmitting data under Antenna Gain Imbalance (AGI), comprising: determining that gains of multiple antennas at a transmission terminal are imbalanced; using a better spatial sub-channel in the multiple antennas to retransmit data when streams transmitted by the multiple antennas adopt a same Modulation and Coding Scheme; and using a better spatial sub-channel in the multiple antennas to retransmit data and/or using a single-stream approach to retransmit data when the streams transmitted by the multiple antennas adopt different Modulation and Coding Schemes. | ||
