Abstract

Embodiments of the present disclosure relate to positioning. A first device performs positioning measurements of a first set of reference signals in a first frequency range. If the first device determines that quality of service requirements for positioning the first device are satisfied, the first device transmits a first measurement report to a second device. The first measurement report only comprises a first set of measurement results associated with the first set of reference signals.

First claim

What is claimed is:

1 . A first device, comprising:
at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first device to: perform positioning measurements of a first set of reference signals in a first frequency range; and in accordance with a determination that quality of service requirements for positioning the first device are satisfied based on performing the positioning measurements of the first set of reference signals, transmit a first measurement report to a second device, the first measurement report only comprising a first set of measurement results associated with the first set of reference signals.

2 . The first device of claim 1 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the first device to:
receive, from the second device, assistance information associated with the positioning; and determine whether the quality of service requirements are satisfied based on the assistance information.

3 . The first device of claim 2 , wherein the assistance information indicates at least one of the following:
timing for the transmission of the first measurement report, a first threshold for a number of available neighbor cells in a first set of neighbor cells transmitting the first set of reference signals, a second threshold for reference signal received powers, RSRPs, of the first set of reference signals, a third threshold for signal to noise ratios, SNRs, of time of arrival of the first set of reference signals, a fourth threshold for RSRPs of Quasi-Colocation reference signals, QCL RS, from the first set of neighbor cells, determination of a line of sight, LoS, status, a fifth threshold for a number of non-LOS links of the first device, or a sixth threshold for RSRPs for reference signals from the non-LoS links.

4 . The first device of claim 3 , wherein the first device is caused to determine that the quality of service requirements are satisfied by determining at least one of the following:
the number of the available neighbor cells is greater than the first threshold and RSRPs of reference signals from the available neighbor cells are greater than the second threshold, the number of the available neighbor cells is greater than the first threshold and SNRs of time of arrival of reference signals from the available neighbor cells are greater than the third threshold, the number of the available neighbor cells is greater than the first threshold and RSRPs of the QCL RS from the available neighbor cells are greater than the fourth threshold, the LoS status in each of the available neighbor cell and the number of the available neighbor cells is greater than the first threshold, or the number of the non-LOS links of the first device is greater than the fifth threshold, RSRPs of reference signals from the non-LOS links are greater than the sixth threshold in each of the available neighbor cell, and the number of the available neighbour cells is greater than the first threshold.

5 . The first device of claim 1 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the first device to:
in accordance with a determination that the quality of service requirements fails to be satisfied, perform positioning measurements of a second set of reference signals in a second frequency range, the second frequency range being different from the first frequency range; and transmit a second measurement report to the second device, the second measurement report comprising the first set of measurement results associated with the first set of reference signals and a second set of measurement results associated with the second set of reference signals.

6 . A first device, comprising:
at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first device to: perform positioning measurements of a first set of reference signals in a first frequency range; and transmit a first measurement report to a second device, the first measurement report only comprising a first set of measurement results associated with the first set of reference signals; receive, from the second device, an indication that positioning measurements of a second set of reference signals are to be performed in a second frequency range, the second frequency range being different from the first frequency range; perform the positioning measurements of the second set of reference signals; and transmit a second measurement report to the second device, the second measurement report only comprising a second set of measurement results associated with the second set of reference signals.

7 . The first device of claim 6 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the first device to:
receive, from the second device, first configuration information about the first set of reference signals.

8 . The first device of claim 6 , wherein the first device is caused to receive the indication by receiving one of the following:
second configuration information about the second set of reference signals, or a signaling for triggering the positioning measurements of the second set of reference signals.

9 . The first device of claim 6 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the first device to:
transmit, to the second device, an indication that the first measurement report only comprises the first set of measurement results associated with the first set of reference signals.

10 . A second device, comprising:
at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the second device to: receive a first measurement report from a first device, the first measurement report only comprising a first set of measurement results associated with a first set of reference signals in a first frequency range; determine whether quality of service requirements for positioning the first device are satisfied based on the first measurement report; and in accordance with a determination that the quality of service requirements are satisfied, determine a position of the first device based on the first measurement report.

11 . The second device of claim 10 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the second device to:
in accordance with a determination that the quality of service requirements fail to be satisfied, transmit, to the first device, an indication that positioning measurements of a second set of reference signals are to be performed, the second set of reference signals being transmitted in a second frequency range that is different from the first frequency range; and receive a second measurement report from the first device, the second measurement report only comprising a second set of measurement results associated with the second set of reference signals.

12 . The second device of claim 10 , wherein the at least one memory and the computer program code configured to, with the at least one processor, further cause the second device to:
transmit, to the first device, first configuration informat
