PRECODING MATRIX INDICATOR (PMI) INFORMATION TRANSMISSION METHOD AND DEVICE

摘要

Disclosed are a precoding matrix indicator (PMI) information transmission method and device, for realizing the feedback and receiving of PMIs. The PMI information feedback method provided in the present application server includes: UE determining the feedback of a PMI and a feedback mode used for feeding back the PMI; the UE determining a rank indicator (RI) and a precoding matrix in a compressed precoding matrix set and determining an RI and first PMI combined coding information value according to a preset RI and first PMI combined coding information value and a correlation list of RIs and codebook indices; and the UE employing the feedback mode to send the determined RI and first PMI combined coding information value to a base station.
