Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE measures, at a first time point, a first set of reference signals to determine a first set of values corresponding to a set of CSI parameters. The UE determines value differences between the first set of values and a set of reference values corresponding to the set of CSI parameters. The UE sends a first CSI report including variation indicators indicating the value differences.
Claims18
A method of wireless communication of a user equipment (UE), comprising:
- measuring, at a first time point, a first set of reference signals to determine a first set of values of a non-differential channel state information (CSI) report, the first set of values corresponding to a set of CSI parameters;
- determining value differences between the first set of values and a set of reference values corresponding to the set of CSI parameters, wherein the set of reference values are generated by a prediction model for the first time point based on one or more sets of prior values, corresponding to the set of CSI parameters, for one or more time points prior to the first time point;
- and
- sending a first differential CSI report including variation indicators indicating the value differences, for reconstructing the first set of values of the non-differential CSI report by the base station based on the value differences and the set of reference values generated by a prediction model at the base station, without reporting the first set of values.
An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- measure, at a first time point, a first set of reference signals to determine a first set of values of a non-differential channel state information (CSI) report, the first set of values corresponding to a set of CSI parameters;
- determine value differences between the first set of values and a set of reference values corresponding to the set of CSI parameters, wherein the set of reference values are generated by a prediction model for the first time point based on one or more sets of prior values, corresponding to the set of CSI parameters, for one or more time points prior to the first time point;
- and
- send a first differential CSI report including variation indicators indicating the value differences for reconstructing the first set of values of the non-differential CSI report by the base station based on the value differences and the set of reference values generated by a prediction model at the base station, without reporting the first set of values.
A non-transitory computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:
- measure, at a first time point, a first set of reference signals to determine a first set of values of a non-differential channel state information (CSI) report, the first set of values corresponding to a set of CSI parameters;
- determine value differences between the first set of values and a set of reference values corresponding to the set of CSI parameters, wherein the set of reference values are generated by a prediction model for the first time point based on one or more sets of prior values, corresponding to the set of CSI parameters, for one or more time points prior to the first time point;
- and
- send a first differential CSI report including variation indicators indicating the value differences for reconstructing the first set of values of the non-differential CSI report by the base station based on the value differences and the set of reference values generated by a prediction model at the base station, without reporting the first set of values.
