Massive MIMO Architecture

摘要

Techniques are disclosed relating to a massive MIMO base station architecture. In some embodiments, a base station is configured to combine signals received by multiple antennas and, for at least a subset of processing elements included in the base station, each processing element is configured to operate on a different portion of the combined signals. In these embodiments, each portion includes signals from multiple antennas. In some embodiments, the portions are different time and/or frequency portions of the combined signals. In some embodiments, this distributed processing may allow the number of antennas of the base station to scale dramatically, provide dynamic re-configurability, facilitate real-time reciprocity-based precoding, etc.
