A user equipment (UE) generates a positioning state information (PSI) report that is transmitted to a network entity in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to reduce latency. The PSI report may be generated based on a plurality of PSI report elements determined from positioning measurements performed by the UE. Each PSI report element includes information related to positioning measurements performed by the UE. One or more of the PSI report elements may be compressed based on a compression configuration, in order to reduce overhead. If the size of the PSI report elements, after one or more PSI report elements are compressed, is larger than the lower layer channel container, one or more of the PSI reports may be omitted from the PSI report. A network entity may receive and process the PSI report based on the compression configuration.
