PERIODIC AND APERIODIC CHANNEL STATE INFORMATION REPORTING FOR ADVANCED WIRELESS COMMUNICATION SYSTEMS

摘要

User equipment and a method for a transceiver operable to communicate with the at least one base station. The processing circuitry configured to control the transceiver to receive a first set of CSI-RS according to a first CSI process configuration; receive a second set of CSI-RS according to a second CSI process configuration; transmit a PUCCH comprising a first RI on a RI reporting subframe derived according to the first CSI process configuration, wherein the first RI is derived using recent channel estimates; and transmit a second PUCCH comprising a channel quality indicator (CQI) and a first PMI on a CQI/PMI reporting subframe derived according to the first CSI process configuration, wherein the CQI and the first PMI are derived using (i) the recent channel estimates, (ii) recent interference estimates, (iii) a second RI, and (iv) at least one of a third RI and a second PMI.
