Abstract
Methods, systems, and devices for wireless communications are described for closed-loop precoding for multiple-input multiple-output for transmitter circle arrays, for example uniform circular array panels. In some aspects, a base station including a transmitter circle array may steer a beam to a user equipment (UE) using codebooks, quantization rules, and feedback from the user equipment. In some aspects, the same transmitter circle array may be used for both backhaul communications with a device at a fixed location, for example using beams formed via discrete Fourier transform (DFT) vectors, and access communications with a UE via non-DFT beams coded using closed-loop precoding.
