Title:
A METHOD TO TRANSMIT CHANNEL STATE INFORMATION REFERENCE SIGNALS IN LARGE MIMO SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/033148
Kind Code:
A1
Abstract:
The disclosure relates to technology for transmitting a channel state information reference signal in a communications network. A channel state information reference signal period is computed based on an estimated Doppler metric corresponding to one or more user equipment in the network. The one or more user equipment are grouped into ranges based on the estimated Doppler metric corresponding to a respective one of the one or more user equipment. The one or more user equipment in each group are then configured to receive the channel state information reference signal with the corresponding channel state information reference signal period based on the Doppler metric, and the channel state information reference signal is transmitted to the one or more user equipment according to the channel state information reference signal period.
