QUANTIZATION SCHEME FOR CHANNEL STATE INFORMATION REPORTS - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18043345 Titled 'QUANTIZATION SCHEME FOR CHANNEL STATE INFORMATION REPORTS'
Simplified Explanation
The abstract describes a method for generating channel state reports in a wireless communication system. A base station sends a reference signal over multiple ports, and a user equipment (UE) receives and measures the amplitudes of the signal on these ports. The UE then divides the ports into two subgroups, either determined by the base station or the UE itself. The UE quantizes and normalizes the amplitude and phase measurements separately for each subgroup. Finally, the UE generates a channel state report based on these normalized and quantized values.
Original Abstract Submitted
Aspects of the disclosure relate to the generation of channel state reports. A base station transmits a reference signal over a plurality of ports. A user equipment (UE) receives the reference signal and measure amplitudes of the reference signal over a plurality of ports. A first subgroup of the plurality of ports and a second subgroup of the plurality of ports are determined. In embodiments, the port groupings may be determined by the base station, which transmits an identification of the groupings to the user equipment. Alternatively, the UE may determine the port groupings. After determining the port groupings, the UE separately quantizes and normalizes the measured amplitude values in each port grouping. The UE may also separately quantize and normalize the phase measurements in each port groups. The UE generates a channel state report based on the normalized and quantized amplitude and phase values.
