Reporting multiple processes for aperiodic channel state information

摘要

A method and apparatus for transmitting channel state information (CSI) transmitted from a user equipment (UE) through a PUSCH transmission in an uplink (UL) cell is provided, wherein the UL cell indicates a CSI transmission. Associated with a downlink (DL) cell that responds to reception of a downlink control information (DCI) format that includes a CSI request field, the CSI transmission includes a measurement of each reference signal and a CSI process set associated with each Corresponds to one. The method includes obtaining an indication of a CSI process set for CSI transmission from the CSI request field, and transmitting a CSI for the CSI process set indicated by the CSI request field, wherein the CSI request field includes a first CSI request field. A 2-bit first CSI process set with a set of interpretations is included.
