Signaling methods for frequency offset estimation using reference signals
Methods, systems, and devices for wireless communication are described. Reference signals may be used for estimating frequency offset at a wireless device. For example, a first wireless device may identify a frequency offset estimation request for a second wireless device. The first wireless device may in turn transmit an initialization signal to the second wireless device to estimate the frequency offset, where the initialization signal may identify parameters for the transmission of a reference signal. The reference signal may then be transmitted to the second wireless device, and the second wireless device may estimate the frequency offset. In some examples, the second wireless device may send a request for the reference signal, where the request may include proposed parameters for the transmission of the reference signal. The first wireless device may accept the proposed parameters, or provide different parameters, and transmit the reference signal.
