Apparatus, methods, and computer-readable media for coexistence of multiple uplink control channel formats for wireless communication with power spectral density limitation are disclosed herein. A user equipment (UE) may communicate, with a base station (BS) over a random access channel on a first set of random access resources or a second set of random access resources, a random access request based on a comparison between an intended transmit power of the random access request and a reference transmit power threshold. The UE may communicate, on a first set of uplink resources, a control message for initial network access when the random access request is communicated on the first set of random access resources. The UE also may communicate, on a second set of uplink resources, the control message when the random access request is communicated on the second set of random access resources.
