For unpaired spectrum operation, a DL BWP from the set of configured DL BWPs with an index provided by higher layer parameter bwp-Id may be linked with an UL BWP from the set of configured UL BWPs with index provided by higher layer parameter bwp-Id when the DL BWP index and the UL BWP index are same. For unpaired spectrum operation, a UE 102 does not expect to receive a configuration where the center frequency for a DL BWP is different than the center frequency for an UL BWP when the bwp-Id of the DL BWP is same as the bwp-Id of the UL BWP.
For each DL BWP in a set of DL BWPs on the primary cell, a UE 102 may be configured with control resource sets for every type of common search space and for UE-specific search space. The UE 102 does not expect to be configured without a common search space on the PCell, or on the PSCell, of the MCG in the active DL BWP.
