摘要： In particular embodiments, a method for determining a beam-forming weight for coordinated multipoint communication with a first network node is performed by a wireless device in a cluster set of wireless devices configured to operate as a virtual device. The method includes receiving from a first network node, via a first channel, a first network RS coded with a first network beamforming weight associated with the cluster set. A second network RS is received from a second network node via the first channel. A device beamforming weight is calculated based on the first network RS received from the first network node and the second network RS received from the second network node. The calculation may be performed during a first iteration and may be independent of any channel information from any other wireless device in the cluster set of the wireless devices operating as a virtual device. The calculation of the first iteration may also be independent of any channel information associated with a second channel between the other wireless devices of the cluster set and the first network node. A first device RS coded with the device beamforming weight is sent to the first network node via the first channel.
