Timing group indication for positioning measurement

A wireless node, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• determine first timing information associated with a first one or more reference signals for positioning or with a first one or more measurements associated with the first one or more reference signals for positioning, the first timing information including a transmit or receive hardware group delay, timing error, timing calibration error, or a combination thereof;
• determine that the first one or more reference signals or the first one or more measurements are associated with one of a plurality of timing groups at least based on the first timing information;
• perform the first one or more measurements associated with the first one or more reference signals for positioning;
• transmit, via the at least one transceiver, an indication of the associated timing group;
• and
• transmit, via the at least one transceiver, a measurement report based on the first one or more measurements, wherein the indication of the associated timing group comprises a respective indication of a respective timing group associated with each measurement in the measurement report,
• wherein the first one or more reference signals for positioning include one or more receive (Rx) reference signals for positioning received at the wireless node,
• wherein the wireless node corresponds to a user equipment (UE) and the one or more Rx reference signals for positioning comprise a downlink positioning reference signal (DL-PRS), a synchronization signal block (SSB), a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), a tracking reference signal (TRS), a channel state information reference signal (CSI-RS), physical dedicated shared channel (PDSCH), a physical sidelink shared channel (PSSCH), or a downlink demodulation reference signal (DMRS), or a combination thereof, or
• wherein the wireless node corresponds to a network component and the one or more Rx reference signals for positioning comprise an uplink sounding reference signal for positioning (UL-SRS-P), an UL-SRS for multiple input multiple output (MIMO), a physical random access channel (PRACH) signal, a physical uplink shared channel (PUSCH) communication, or an uplink DMRS, or a combination thereof.
