Abstract
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include a RIS that can receive, from a satellite, a positioning reference signal. The RIS can further reflect the positioning reference signal to produce a reflection positioning reference signal radiated towards a network device for positioning of the network device.
Claims26
A reconfigurable intelligent surface (RIS) for wireless communication, the RIS comprising:
- at least one transceiver configured to receive, from a satellite, a positioning reference signal;
- and
- at least one element configured to reflect the positioning reference signal to produce a reflection positioning reference signal radiated towards a network device for positioning of the network device,
- where the at least one transceiver is configured to receive, from a network entity, a data signal comprising assistance data, wherein the assistance data comprises at least one of a watermark identification (ID) for the reflection positioning reference signal, a positioning reference signal (PRS) ID associated with the watermark ID, a timer for the network device to switch between positioning detection modes, or a quasi-colocation configuration (QCL) between synchronization signal blocks (SSBs) and positioning reference signals (PRSs) for the positioning of the network device;
- and
- the at least one element is configured to reflect the data signal to produce a reflection data signal radiated towards the network device.
A method of wireless communication performed at a reconfigurable intelligent surface (RIS), the method comprising:
- receiving, by the RIS from a satellite, a positioning reference signal;
- and
- reflecting, by the RIS, the positioning reference signal to produce a reflection positioning reference signal radiated towards a network device for positioning of the network device, wherein the method further comprising:
- receiving, by the RIS from a network entity, a data signal comprising assistance data, wherein the assistance data comprises at least one of a watermark identification (ID) for the reflection positioning reference signal, a positioning reference signal (PRS) ID associated with the watermark ID, a timer for the network device to switch between positioning detection modes, or a quasi-colocation configuration (QCL) between synchronization signal blocks (SSBs) and positioning reference signals (PRSs) for the positioning of the network device;
- and
- reflecting, by the RIS, the data signal to produce a reflection data signal radiated towards the network device.
