A Channel State Information CSI measurement method, comprising steps of: receiving channel state measurement information from a network side; and performing CSI measurement in accordance with the channel state measurement information, wherein the channel state measurement information comprising a Cell-specific Reference Signal CRS from a set of CRS ports corresponding to vertical beams having an identical V shift in a vertical dimension, wherein the V shift determines shift values of CRS patterns in different vertical beams in the vertical dimension, in a frequency domain, characterised in that: in the case that there is only one CRS port corresponding to the vertical beams having the identical V shift, the CRS is transmitted over a Physical Broadcast Channel PBCH in a single-port mode via the CRS port corresponding to all the vertical beams; in the case that there are two CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH in a Space Frequency Block Code SFBC mode via the set of CRS ports corresponding to the vertical beams having the identical V shift; and in the case that there are four CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH both in an SFBC mode and a Frequency Switched Transmit Diversity FSTD mode via the set of CRS ports corresponding to the vertical beams having the identical V shift. receiving channel state measurement information from a network side; and performing CSI measurement in accordance with the channel state measurement information, wherein the channel state measurement information comprising a Cell-specific Reference Signal CRS from a set of CRS ports corresponding to vertical beams having an identical V shift in a vertical dimension, wherein the V shift determines shift values of CRS patterns in different vertical beams in the vertical dimension, in a frequency domain, characterised in that: in the case that there is only one CRS port corresponding to the vertical beams having the identical V shift, the CRS is transmitted over a Physical Broadcast Channel PBCH in a single-port mode via the CRS port corresponding to all the vertical beams; in the case that there are two CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH in a Space Frequency Block Code SFBC mode via the set of CRS ports corresponding to the vertical beams having the identical V shift; and in the case that there are four CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH both in an SFBC mode and a Frequency Switched Transmit Diversity FSTD mode via the set of CRS ports corresponding to the vertical beams having the identical V shift. in the case that there is only one CRS port corresponding to the vertical beams having the identical V shift, the CRS is transmitted over a Physical Broadcast Channel PBCH in a single-port mode via the CRS port corresponding to all the vertical beams; in the case that there are two CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH in a Space Frequency Block Code SFBC mode via the set of CRS ports corresponding to the vertical beams having the identical V shift; and in the case that there are four CRS ports corresponding to the vertical beams having the identical V shift, the CRS is transmitted over the PBCH both in an SFBC mode and a Frequency Switched Transmit Diversity FSTD mode via the set of CRS ports corresponding to the vertical beams having the identical V shift.
