A wireless transmit receive unit (WTRU) and methods are disclosed for mitigating radar interference with uplink control channels may include receiving configuration information including a set of dedicated physical uplink control channel (PUCCH) resources for scheduling requests (SRs), the set includes first PUCCH resources of an UL BWP, and second PUCCH resources of the UL BWP different from the first PUCCH resources. SRs are sent using the first PUCCH resources while the second PUCCH resources are suspended from use. The WTRU receives signaling from a network to suspend one or more of the first PUCCH resources, and unsuspend one or more of the second PUCCH resources. Thereafter, subsequent SRs are sent using only unsuspended PUCCH resources of the UL BWP and not the suspended PUCCH resources, in response to the received signaling from the network. Additional embodiment are disclosed.
