1. A communication method performed by a user equipment (UE), comprising:
attempting, at the UE, to decode a first Physical Downlink Control Channel (PDCCH) in a Common Search Space (CSS), wherein the first PDCCH is scrambled by a first Radio Network Temporary Identifier (RNTI), the first PDCCH has a first payload size, and the first PDCCH starts at a first Control Channel Element (CCE) index;
attempting, at the UE, to decode a second PDCCH in a User equipment-specific Search Space (USS), wherein the second PDCCH is scrambled by a second RNTI, the second PDCCH has a second payload size, and the second PDCCH starts at a second CCE index;
determining, at the UE, that (i) the first RNTI is same as the second RNTI; (ii) the first payload size is same as the second payload size; and (iii) the first CCE index is same as the second CCE index; and
receiving, at the UE, data at least based on the first PDCCH.
