1. A method for wireless communication at a scheduling entity in a wireless communication network, the method comprising:
configuring a portion of an operating bandwidth to serve as a bandwidth part (BWP) used for communicating with a user equipment (UE) over the wireless communication network;
defining two or more sub-BWPs at different frequency locations within the BWP, each sub-BWP including resource blocks provided in the BWP;
providing a scheduling gap when a frequency hop is scheduled between two or more sub-BWPs at the UE, wherein the scheduling gap accommodates radio frequency retuning at the UE;
transmitting a physical downlink control channel (PDCCH) in a first sub-BWP; and
transmitting a physical downlink shared channel (PDSCH) scheduled by the PDCCH with a preceding hop in a second sub-BWP the PDSCH commencing after the scheduling gap,
wherein the scheduling gap is provided after the PDCCH and comprises a slot offset that includes an integer number of slots,
wherein the PDSCH conforms to physical downlink shared channel mapping type A defined by the Third Generation Partnership Project (3GPP), and
wherein the PDCCH and PDSCH are prohibited from being transmitted in a same slot.
