1. A first wireless communication device, comprising:
a memory; and
one or more processors, coupled to the memory, configured to cause the first wireless communication device to:
transmit, to a second wireless communication device, a time and/or frequency synchronization message using a first radio frequency (RF) technology, wherein the time and/or frequency synchronization message is used to obtain synchronization information for a second RF technology;
transmit, to the second wireless communication device, a first set of ranging measurement signals associated with the second RF technology; and
receive, from the second wireless communication device, a second set of ranging measurement signals associated with the second RF technology,
wherein the time and/or frequency synchronization message is transmitted in a first set of one or more ranging slots, wherein at least a first ranging measurement signal of the first set of ranging measurement signals is transmitted in a first ranging slot after the first set of one or more ranging slots, wherein at least a first ranging measurement signal of the second set of ranging measurement signals is received in the first ranging slot, wherein at least a second ranging measurement signal of the first set of ranging measurement signals is transmitted in a second ranging slot after the first ranging slot, and wherein at least a second ranging measurement signal of the second set of ranging measurement signals is received in the second ranging slot.
