Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive first control information that enables the UE to skip transmission of a scheduled uplink message via an uplink skipping operation. The UE may receive second control information that requests the UE to switch an active BWP at the UE from a first BWP to a second BWP. The UE may receive third control information that schedules transmission of an uplink message at the UE during a time interval. Application of the uplink skipping operation to the uplink message may be based on the time interval being after the switch and whether the UE is scheduled to transmit a reference signal during the time interval. The UE may transmit, during the time interval and via the second BWP, a signal that is based on whether the UE applies the uplink skipping operation during the time interval.

In some aspects, a radar device may receive a received signal comprising a reflected frequency modulated continuous wave (FMCW) radar signal and interference. The radar device may identify the reflected FMCW radar signal based at least in part on performing a phase based search procedure to facilitate removing the interference from the received signal. The radar device may perform an action based at least in part on a characteristic of the identified reflected FMCW radar signal. Numerous other aspects are described.

Apparatus and methods are disclosed for determining, on a small form factor 5G communication device, the range of a target object include receiving, at a receiving antenna of the small form factor communication device, a composite signal where the composite signal includes a target reflection signal and a mutual coupling (MC) leakage signal, generating a composite beat waveform by mixing the composite signal with an original signal, where the composite beat includes target beat and MC leakage beat waveform components, isolating the target beat waveform by subtracting from the composite beat waveform a weighted, k-delayed composite beat waveform, where for a configured k the target beat waveforms are uncorrelated and the MC leakage beat waveforms are correlated, and determining, using the target beat waveform, a range of the target object from the small form factor device.
