1Loss of time
If positioning measurement data is managed in existing wireless communication systems, then positioning functionality is provided, but signaling overhead increases and latency is not sufficiently reduced
Solution Approach 1:
The patent combines positioning measurement data with uplink data transmissions by multiplexing them on the same physical uplink shared channel (PUSCH). This merging approach allows positioning data to be transmitted alongside regular data traffic, thereby reducing signaling overhead and latency without requiring separate dedicated positioning channels.
Solution Approach 2:
The patent enables the uplink data channel (PUSCH) to serve dual purposes: transmitting both regular uplink data and positioning measurement data. This multi-functionality eliminates the need for separate positioning-specific uplink channels, reducing overall signaling overhead while maintaining efficient positioning data transmission.
2Productivity
If multiple wireless sensors are deployed to enhance network coverage and capacity, then spectral efficiency improves, but system complexity and data management burden increase
Solution Approach 1:
The patent segments positioning measurement data from different wireless sensors and multiplexes them efficiently on shared uplink resources. By organizing and transmitting positioning data from multiple sensors through a standardized multiplexing framework, the system manages increased sensor deployments without proportionally increasing complexity.
Solution Approach 2:
The patent merges positioning data transmissions with regular data traffic on the same uplink physical channel. This approach allows the system to support multiple wireless sensors for enhanced spectral efficiency while avoiding the complexity overhead of separate positioning channels for each sensor.
3Productivity
If positioning measurement data is transmitted using existing uplink channels, then positioning information is delivered, but resource utilization efficiency is suboptimal
Solution Approach 1:
The patent merges positioning measurement data with uplink data transmissions on the PUSCH channel. This combination improves resource utilization efficiency by making use of existing allocated uplink resources for dual purposes, thereby reducing signaling overhead and avoiding the need for additional dedicated positioning transmission resources.
Solution Approach 2:
The patent implements dynamic multiplexing where positioning measurement data is flexibly incorporated into uplink data transmissions based on current traffic conditions and positioning requirements. This dynamic approach optimizes resource utilization by adapting to varying data and positioning needs without rigid resource allocation.

AI summary
Disclosed are techniques for wireless communication. In an aspect, a first communication node (e.g., UE, BS, etc.) obtains one or more measurements associated with one or more PRSs (e.g., uplink PRS(s), downlink PRS(s), etc.) The first communication node populates measurement value(s) into measurement field(s) of a report based on the one or more measurements. The first communication node identifies at least one unpopulated measurement field associated with the report, and transmits, to a second communication node, the report in association with an indication of the at least one unpopulated measurement field. The second communication node (e.g., UE, BS, etc.) performs position computing function based on the report.
