Abstract
Presented are systems and methods for uplink frequency selective precoding. A wireless communication device may receive a first signaling from the wireless communication node. The first signaling may include a plurality of precoding information associated with a plurality of port groups. The wireless communication device may determine signals precoded according to the plurality of precoding information. The wireless communication device may transmit the signals to the wireless communication node.
