Abstract: Disclosed are systems and methods of selecting physical downlink control channel (PDCCH) candidates for non-coherent joint transmission (NC-JT) in a wireless network. For instance, first and second sets of ControlResourceSet and SearchSpace parameters can be configured for a UE. The first and second sets of ControlResourceSet and SearchSpace parameters are configured on a first downlink (DL) component carrier to enable NC-JT. A control channel element (CCE) limit can be determined for the first and second sets of ControlResourceSet and SearchSpace parameters. One or more PDCCH candidates can then be selected for the first and second sets of ControlResourceSet and SearchSpace parameters based at least in part on the determined CCE limits. NC-JT communication including at least a first communication from a first transmission and reception point (TRP), and a second communication from a second TRP can then be received.
