AI Technical Summary
Technical Problem
Reduced Capability (RedCap) UEs face challenges in accurately determining their position due to bandwidth limitations, which prevent them from processing high-bandwidth Position Reference Signals (PRSs).
Method used
The implementation of receive frequency hopping in RedCap UEs, allowing them to measure downlink PRSs across multiple frequency hops, with capabilities such as maximum supported PRS bandwidth, possible number of frequency hops, maximum bandwidth per hop, and minimum hop overlap being indicated and configured.
Benefits of technology
This approach enables RedCap UEs to accurately determine their position even when they cannot accommodate high-bandwidth PRSs, by effectively utilizing frequency hopping to process PRSs within their bandwidth capabilities.

Abstract
This disclosure provides systems, methods, and devices for wireless communication that support processing high bandwidth position references signals (PRSs) at a reduced capability (RedCap) User equipment (UE). The UE reports a frequency hopping capability and a measurement gap. In a first aspect, a method of wireless communication includes a method of wireless communication performed at a User Equipment. The UE transmits an indication of a capability of the UE to perform receive frequency hopping to measure a downlink positioning reference signal (DL-PRS), where the indication of the capability includes at least one of a maximum supported PRS bandwidth (BW) with frequency hopping, a possible number of frequency hops, maximum BW per hop, and minimum hop overlap. Optionally, the UE also transmits a report of a total PRS BW measured by the UE and / or an indication that a measurement with frequency hopping was performed. Other aspects and features are also claimed and described.
