Wireless communications systems and methods related to communications in a network that supports data transmitted in an unlicensed frequency band and a licensed frequency band are provided. A first wireless communication device transmits in a first frequency band, a first system information signal indicating a first random access configuration for a second frequency band. The first wireless communication device transmits in a third frequency band, a second system information signal indicating a second random access configuration for the second frequency band. The first and third frequency bands are different frequency bands. Additionally, the first wireless communication device performs with a second wireless communication device, a random access procedure based on at least one of the first random access configuration or the second random access configuration.
