Abstract
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving a reflection signal from a target. In some cases, the reflection signal may include tracking reference signal (TRS) resources and radar reference signal (RS) resources. In some cases, the reflection signal may include sidelink (SL) single sideband (SSB) resources and SL radar RS resources. The process further includes determining a Doppler estimation for the target based on the reflection signal.
Claims26
An apparatus for wireless communications, the apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- receive a reflection signal from a target, wherein the reflection signal comprises tracking reference signal (TRS) resources and radar reference signal (RS) resources, and wherein the TRS resources and the radar RS resources are associated based on phase continuity between the TRS resources and the radar RS resources;
- and
- determine a Doppler estimation for the target based on the reflection signal and based on the phase continuity between the TRS resources and the radar RS resources.
A method for wireless communications at a user equipment (UE), the method comprising:
- receiving, at the UE, a reflection signal from a target, wherein the reflection signal comprises tracking reference signal (TRS) resources and radar reference signal (RS) resources, and wherein the TRS resources and the radar RS resources are associated based on phase continuity between the TRS resources and the radar RS resources;
- and
- determining, at the UE, a Doppler estimation for the target based on the reflection signal and based on the phase continuity between the TRS resources and the radar RS resources.
An apparatus for wireless communications, the apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- receive a reflection signal from a target, wherein the reflection signal comprises sidelink (SL) single sideband (SSB) resources and SL radar reference signal (RS) resources;
- and
- determine a Doppler estimation for the target based on the reflection signal, wherein the reflection signal is received via a Universal Mobile Telecommunications System Air interface (Uu).
