| titleOfInvention | Antenna combining for massive mimo scheme |
| abstract | In this disclosure, methods for antenna combining to meet the pilot requirement of the massive MIMO system, and apparatuses for the same are provided. In a base station perspective of view, the base station, receiving first pilot signals transmitted via each of multiple antennas of a user equipment (UE), selects one or more reference codebooks based on channel qualities of the received first pilot signals. Then, the base station may select one or more sub-channels for each of the reference codebooks. Based on this, the base station may determine one or more virtual channels, wherein each of the virtual channels comprises one reference codebook and the one or more sub channels selected for the one reference codebook, wherein the sub-channels are selected to minimum distance between corresponding virtual channel and corresponding reference codebook. Based on this, the base station transmits antenna combining information to the UE, wherein the antenna combining information combines the multiple antennas of the UE into one or more antenna groups corresponding to the one or more virtual channels; and receive second pilot signals transmitted by the UE based on the antenna combining information. |
