Random access channel (RACH) transmission with cross-band downlink/uplink (DL/UL) pairing

An apparatus comprising:

• a transceiver configured to:
• communicate, with a second wireless communication device, a random access configuration for a first frequency spectrum, the random access configuration communicated in a second frequency spectrum different from the first frequency spectrum, wherein the random access configuration includes a target reception power level for a random access signal based on channel characteristic differences between the first frequency spectrum and the second frequency spectrum;
• communicate, with the second wireless communication device, a communication signal in the first frequency spectrum based on the random access configuration;
• and
• communicate, with the second wireless communication device, the random access signal in the first frequency spectrum based on the communication signal and the target reception power level for the random access signal.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to communicate, with a second wireless communication device, a random access configuration for a first frequency spectrum, the random access configuration communicated in a second frequency spectrum different from the first frequency spectrum, wherein the random access configuration includes a target reception power level for a random access signal based on channel characteristic differences between the first frequency spectrum and the second frequency spectrum;
• code for causing the first wireless communication device to communicate, with the second wireless communication device, a communication signal in the first frequency spectrum based on the random access configuration;
• and
• code for causing the first wireless communication device to communicate, with the second wireless communication device, the random access signal in the first frequency spectrum based on the communication signal and the target reception power level for the random access signal.
