Massive mimo communication technique

Abstract

Methods and apparatus for using a first number of antennas at one base station, e.g., at a first CBSD, in combination with a second, e.g., lesser number of antennas at another base station to provide different wireless terminals communications channels with different channel conditions are described. A ‘relay mode’ of operation at the second base station facilitates communication of data from the first base station. In this way the second base station is used to relay data sent from the first base station while the UE perceives the data as having been sent over the air by the first base station. The channels from the first and second base stations operate together providing a composite channel that will have different channel conditions than would be possible using simply the antennas of the first base station. Differences in channels to different UEs facilitates transmission scheduling at the first base station.
