1. A user equipment (UE), comprising:
a transceiver configured to connect to a base station; and
a processor communicatively coupled to the transceiver and configured to perform operations comprising:
receiving a physical random access channel (PRACH) resource on a first sub-band of a component carrier (CC), wherein the CC is divided into a plurality of sub-bands; and
receiving a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on a second sub-band of the CC, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource, wherein a switching gap is predefined between the PRACH resource and the Type1-PDCCH CSS set, wherein the predefined switching gap is based on a sub-carrier spacing and is larger than or equal to a threshold.
