Abstract
In a wireless communication system, dynamic changes of a code block (CB) to resource element (RE) mapping type may improve decoding performance in some scenarios. A user equipment may provide an indication of a preferred CB mapping type. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. A UE may receive the PDSCH and determine a second CB mapping type that is preferred by the UE based on a metric. The UE may transmit an indicator of the second CB mapping type, for example, as a one-bit or two-bit indicator, which may be coupled with a channel state information (CSI) report or signaled in uplink control information (UCI) independently from a CSI report. The base station may consider the indicator when selecting a new dynamic CB mapping type for the UE.
