3. A method for receiving physical channels, comprising:receiving, by a User Equipment (UE), a Physical Downlink Control Channel (PDCCH), the PDCCH being transmitted in a resource from a first bandwidth part (BWP) with a first associated numerology, wherein the first BWP with the first associated numerology is indicated by a first message for the PDCCH; and
receiving, by the UE, a Physical Downlink Sharing Channel (PDSCH), the PDSCH being transmitted in a resource from a second BWP with a second associated numerology, wherein the second BWP with the second associated numerology is indicated by a second message for the PDSCH,
wherein the PDCCH contains scheduling information of the PDSCH, wherein a value of the first associated numerology is different from a value of the second associated numerology, and wherein each of the first and second associated numerologies is at least one of a Subcarrier Spacing (SCS) or a cyclic prefix (CP).
