Methods, apparatus, systems, and processes for uplink (UL) channel interactivity

Methods, apparatuses, and systems are disclosed. A representative method implemented by a wireless transmit/receive unit includes determining a first beamforming matrix; sending an indication of the first beamforming matrix to a network entity; and receiving, from the network entity, an indication of a second beamforming matrix determined by the network entity from at least the first beamforming matrix for beamforming data to be transmitted. 公开了方法、装置和系统。由无线发射/接收单元实施的一种代表性方法包括确定第一波束成形矩阵；向网络实体发送关于所述第一波束成形矩阵的指示；以及从所述网络实体接收由所述网络实体从至少所述第一波束成形矩阵确定的用于对要传输的数据进行波束成形的第二波束成形矩阵的指示。
