Google patents method for tracking signal phases in multi-code wireless uplinks

Google has filed a patent application for a method that helps wireless devices manage phase tracking reference signals (PT-RS) during uplink transmissions. The system uses control signaling to tell a device which specific ports to use when sending these signals, supporting a setup where multiple data codes are transmitted at once.

Why it mattersThis is a technical improvement for how data is sent from phones to towers, which could help maintain stable connections in complex wireless environments.

In the filing’s own words

Methods and devices in a wireless network determine one or more of a number of phase tracking reference signals, PT-RS, a time-domain density thereof and PT-RS associated port(s). Control signaling for configuring a multi-codeword transmission of at least one PT-RS is transmitted from a network entity to a UE and includes parameters for identifying one or more ports to be used by the UE for transmitting the PT-RS.
