Abstract
A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.
Claims23
A method comprising:
- generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE);
- determining a timing error group (TEG) index corresponding to the generated Rx TEG;
- determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG;
- and
- reporting the positioning measurement associated with the Rx TEG index.
A method comprising:
- generating a transmit timing error group (Tx TEG) based on a time delay of a transmit (Tx) signal, wherein the time delay is a time measured from generation of the Tx signal at a baseband processor to a time of transmission of the Tx signal by a Tx antenna of a user equipment (UE);
- determining a timing error group (TEG) index corresponding to the generated Tx TEG;
- reporting an association information of sounding reference signal (SRS) resources for positioning with the Tx TEG index;
- and
- transmitting the SRS resources for 5G node B (gNB) measurement.
A method comprising:
- generating a receive and transmit timing error group (RxTx TEG) based on a time delay of a receive and transmit signal, wherein the receive and transmit signal is a time measured from an arrival of a downlink (DL) positioning reference signal (PRS) at a receive (Rx) antenna to a time of an uplink (UL) PRS is transmitted from a transmit (Tx) antenna of a user equipment (UE);
- determining a timing error group (TEG) index corresponding to the generated RxTx TEG;
- determining a positioning measurement from the Rx antenna and the Tx antenna;
- and
- reporting the positioning measurement associated with the RxTx TEG index.
