AI Technical Summary

Technical Problem

The prior art is difficult to achieve efficient signal transmission and low latency in 5G mobile communications, especially in scenarios that support a large number of concurrent connections, signal efficiency and positioning accuracy are insufficient.

Method used

By providing an optimized reference signal between the user equipment (UE) and the network entity, an asymmetric resource block combination structure and continuous frequency domain symbol allocation are used to achieve extended carrier phase measurement to improve signal transmission efficiency and position position accuracy.

Benefits of technology

It improves the signal transmission efficiency and low latency performance of 5G mobile communications, enhances network performance in high concurrent connection scenarios, and improves positioning accuracy through improved reference signal structure.

Abstract

Systems, devices, processes, and computer-readable media for wireless communications are disclosed. For example, one example process includes receiving, at a device (e.g., a user equipment (UE) or a component of a UE), a plurality of resource blocks associated with a positioning reference signal (PRS). A combination structure of the PRS is repeated in fewer than all of the plurality of resource blocks. The process includes transmitting a phase measurement report to a first network entity. The phase measurement report includes information associated with a measured phase difference between at least one subcarrier set pair of the plurality of resource blocks. As described herein, a subcarrier set includes at least one subcarrier.
