A method of wireless communications by a user equipment (UE) includes transmitting a request for action for at least one control resource set (CORESET) and associated search space. The action may include configuring, activating, and/or deactivating the at least one CORESET and associated search space. The CORESET may be a dynamic CORESET with a predefined number of search space occasions or a semi-static CORESET. The method also includes communicating in accordance with the request. The request is transmitted using at least one of an uplink radio resource control (RRC) message, a physical uplink control channel (PUCCH), a sounding reference signal (SRS), a random access channel (RACH), or a physical uplink shared channel (PUSCH). The UE may switch, in connection with the request, to a bandwidth part (BWP) configured for the UE.
