Information sending, information determining and relationship determining methods and devices
Information sending, information determining and relationship determining methods and devices are provided. According to the information sending method, a base station sends M parameter sets via high-layer signaling, wherein M>=1, M is a positive integer, each parameter set includes quasi-co-location Non-Zero Power (NZP) Channel State Information Reference Signal (CSI-RS) indication information, and the quasi-co-location NZP CSI-RS indication information is used by a terminal to acquire a large-scale characteristic of a channel; and when M>1, the base station indicates, via a physical-layer control signaling, parameter set selection information of a subframe on which the physical-layer control signaling is sent.
