TECHNIQUES FOR BASEBAND FREQUENCY SHIFTING

Abstract: methods, systems, and devices for wireless communication are described. a passive user equipment (ue) may transmit an indication of a baseband frequency shift type supported by the passive ue for backscatter communications. the baseband frequency shift type may include one or both of a single-side frequency shift or a double-side frequency shift. a network entity may determine a frequency domain resource allocation (fdra) for the passive ue based on receiving the indication. the network entity may transmit an indication of the fdra to the passive ue. the fdra may correspond to the baseband frequency shift type supported by the passive ue. the passive ue may transmit one or more backscatter communications based on the fdra signaled by the network entity. the one or more backscatter communication s may be frequency shifted according to the baseband frequency shift type supported by the passive ue.
