Uplink cancellation indication for supplementary uplink carriers
Aspects are presented which enable a UE to determine a supplementary uplink (SUL) configuration for an uplink cancellation indication (ULCI) for cancelling uplink communications in SUL. The UE receives from a base station a first configuration associated with a first block of an ULCI and associated with at least one of a SUL carrier a non-supplementary uplink (NUL) carrier in a cell. The base station configures the UE with a second configuration associated with a second block of the ULCI and associated with a SUL carrier in the cell, and the UE determines the second configuration. The UE monitors the ULCI based on the first configuration and the second configuration.
