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