Abstract
Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.
Claims24
A method of operating a user equipment (UE), comprising:
- performing a set of measurements of a set of samples associated with a set of positioning reference signal (PRS) occasions;
- combining measurements associated with a subset of samples into a combined measurement in accordance with a combination pattern;
- and
- transmitting, to a position estimation entity, a measurement report comprising the combined measurement and an indication of the combination pattern, wherein the indication of the combination pattern includes a timestamp associated with an earliest of the set of PRS occasions or a latest of the set of PRS occasions.
A method of operating a position estimation entity, comprising:
- receiving, from a user equipment (UE), a measurement report comprising a combined measurement and an indication of a combination pattern, wherein the combined measurement is a combination of measurements of a subset of a set of samples associated with a set of positioning reference signal (PRS) occasions in accordance with the combination pattern, and wherein the indication of the combination pattern includes a timestamp associated with an earliest of the set of PRS occasions or a latest of the set of PRS occasions;
- and
- deriving a position estimate of the UE based at least in part on the combined measurement and the combination pattern.
A user equipment (UE), 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:
- perform a set of measurements of a set of samples associated with a set of positioning reference signal (PRS) occasions;
- combine measurements associated with a subset of samples into a combined measurement in accordance with a combination pattern;
- and
- transmit, via the at least one transceiver, to a position estimation entity, a measurement report comprising the combined measurement and an indication of the combination pattern, wherein the indication of the combination pattern includes a timestamp associated with an earliest of the set of PRS occasions or a latest of the set of PRS occasions.
A position estimation entity, 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:
- receive, via the at least one transceiver, from a user equipment (UE), a measurement report comprising a combined measurement and an indication of a combination pattern, wherein the combined measurement is a combination of measurements of a subset of a set of samples associated with a set of positioning reference signal (PRS) occasions in accordance with the combination pattern, and wherein the indication of the combination pattern includes a timestamp associated with an earliest of the set of PRS occasions or a latest of the set of PRS occasions;
- and
- derive a position estimate of the UE based at least in part on the combined measurement and the combination pattern.
