Abstract (en)

[origin: WO2019192018A1] Disclosed are methods, systems and devices for physical downlink control channel (PDCCH) candidate selection. One example method includes performing a communication operation in one or more of a first set of resources, where the resources of the first set of resources are selected in a selection order from a second set of resources that is larger than the first set of resources, and where the selection order for the first set of resources is based on at least one of a period of a search space set, a downlink control information (DCI) format of the search space set, a starting symbol of the search space set, a component carrier type, a component carrier index or an occasion index.
