CHANNEL STATE INFORMATION REPORTING METHOD AND DEVICE, AND CHANNEL STATE INFORMATION RECEIVING METHOD AND DEVICE

摘要

Provided in the present application are a channel state information reporting method and device and a channel state information receiving method and device, the reporting method comprising: receiving a reference signal sent by a second communication node; and according to a first-class report configuration signaling associated with the reference signal, determining at least one of a first-class channel state information set and a second-class channel state information set and reporting the at least one of the first-class channel state information set and the second-class channel state information set to the second communication node, wherein the first-class channel state information set comprises at least one of the following: a reference signal resource index, a reference signal resource set index, a reference signal resource configuration index, a report configuration index, a reference signal port group index, a reference signal port group set index, a port index and order indication information; and the second-class channel state information set comprises at least one of the following: pre-coding matrix indication information, channel state indication information, a range coefficient, a phase coefficient and reference signal receiving power.
