Zusammenfassung:A method, system and apparatus are disclosed. A first wireless device is provided. The first wireless device includes processing circuitry configured to: determine first beam information based at least in part on second beam information received from a second wireless device via device-to-device communications where the first beam information indicates a first beam selected by the first wireless device for downlink wireless communications, and where the second beam information indicates a second beam selected by the second wireless device for downlink wireless communications; and cause transmission of the first beam information for grid of beams precoder determination.
