Abstract: Techniques of generating CSI reports include designating at least one of the reports as a reference and the other reports as dependent on the reference. For example, a dependent CSI report may have a differential value of a CSI quantity rather than a raw value of the CSI quantity. Because generally for parameters in a CSI report, the differential quantity has a smaller range of values than the raw values of the CSI quantity, a quantization of the differential value of the CSI quantity will have fewer bits than the raw value; for example, for L1-RSRP, the raw value has 7 bits while the differential value has 4 bits. In another example, a dependent value of a CSI quantity is a flag indicating that the CSI quantity value is located in a reference CSI report.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for improved transport block size (TBS) indication and channel quality indicator (CQI) reporting for lower target block error ratios (BLERs). In an example implementation, the method may include a user equipment configuring a plurality of transport block sizes, activating one or more transport block sizes of the plurality of transport block sizes, and determining a first transport block size from an indication received from a network node when more than one transport block sizes of the one or more transport block sizes are activated. The method may further include determining, a second transport block size, the second transport block size determined based at least on the one or more transport block sizes that are activated and the first transport block size, and receiving a downlink transmission from the network node with the second transport block size. In an additional example implementation, the method may include a user equipment determining a channel quality indicator based at least on a physical downlink shared channel received from a network node and transmitting the channel quality indicator to the network node.

Abstract: Systems, methods, apparatuses, and computer program products for channel state information (CSI) configuration and reporting for multi-transmission reception point (TRP) operation are provided. One method may include configuring a user equipment (UE), by a network node, to provide independent channel state information (CSI) feedback per transmission reception point (TRP) and to indicate additional information. The configuring of the UE may include configuring the UE with at least one of several reporting options for generating a combined channel state information (CSI) report.
