<p>A method for configuring Channel State Information (CSI) feedback signalings, a method for feeding back CSI, a method for configuring data demodulation, a method for data demodulation, a method for configuring antenna port information, a method for obtaining antenna port information, base stations and terminals are disclosed. The method for configuring CSI feedback signalings includes: the base station configuring N CSI measurement processes used for measuring and feeding back CSI for the terminal, wherein, each of the N CSI measurement processes is independently configured with one or more of the following signalings through a terminal dedicated higher layer signaling: a codebook subset restriction, Precoding Matrix Indicator-Rank Indicator-Report (PMI-RI-Report), PMI feedback enabled, RI feedback enabled, RI feedback enabled according to reference process, PMI feedback enabled according to reference process, sub-band feedback enabled according to reference process, a feedback mode, a resource location fed back by Physical Uplink Control Channel (PUCCH) corresponding to CSI measurement process, subframe offset and cycle fed back by PUCCH corresponding to CSI measurement process, and an initialization sequence Identifier (ID) of PUCCH corresponding to CSI measurement process; and the base station sending the N CSI measurement processes to the terminal, wherein N is a positive integer.</p> |
