Abstract

Claims (41)

1 . An apparatus comprising at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:

receive a positioning reference signal request;

determine positioning requirements associated with the received positioning reference signal request;

determine capabilities of a terminal device;

determine an antenna array radiation pattern beam width for a position reference signal based, at least partly on the determined positioning requirements and the determined capabilities of the terminal device;

obtain a value for a compensation parameter based on the determined antenna array radiation pattern beam width;

perform beam steering towards a target access node; and

perform a timing compensation using the compensation parameter with the obtained value.

2 . An apparatus according to claim 1 , wherein obtaining the value for the compensation parameter is further based on the apparatus being further caused to perform an angle of arrival estimation for the target access node.

3 . An apparatus according to claim 1 , wherein the value for the compensation parameter is obtained from a look-up table stored in the terminal device.

4 . An apparatus according to claim 1 , wherein the value for the compensation parameter is obtained by utilizing a determined mapping function between an input and a corresponding output.

5 . An apparatus according to claim 4 , wherein the input comprises at least one of the following: a beam index and/or an antenna array configuration; and wherein the output comprises the value for the compensation parameter.

6 . An apparatus according to claim 1 , wherein the value for the compensation parameter is obtained by calculating it based on radiation patterns stored in the terminal device.

7 . An apparatus according to claim 1 , wherein the apparatus is further caused to compensate a time of arrival of a position reference signal based on the obtained pre-determined value for the compensation parameter.

8 . An apparatus according to claim 1 , wherein the apparatus is further caused to compensate a time of departure of a position reference signal based on the obtained pre-determined value for the compensation parameter.

9 . An apparatus according to claim 1 , wherein the apparatus is further caused to obtain another pre-determined value for another compensation parameter.

10 . An apparatus according to claim 1 , wherein the positioning requirements comprise one or more of the following: measurement accuracy, positioning technique, channel coherency time and/or number of target access nodes.

11 . An apparatus according to claim 1 , wherein the capabilities of a terminal device comprise one or more of the following: number of antenna arrays comprised in the terminal device, an antenna array type, an antenna array size, a number of transmitter chains and/or a number of receiver chains.

12 . An apparatus according to claim 1 , wherein the terminal device comprises at least one of the following: a one-dimensional antenna array and/or two-dimensional antenna array.

13 . An apparatus according to claim 1 , wherein the apparatus is the terminal device.

14 . A method comprising:

receiving a positioning reference signal request;

determining positioning requirements associated with the received positioning reference signal request;

determining capabilities of a terminal device;

determining an antenna array radiation pattern beam width for a position reference signal based, at least partly on the determined positioning requirements and the determined capabilities of the terminal device;

obtaining a value for a compensation parameter based on the determined antenna array radiation pattern beam width;

performing beam steering towards a target access node; and

performing a timing compensation using the compensation parameter with the obtained value.

15 . A method according to claim 14 , wherein obtaining the value for the compensation parameter is further based on the method being further caused to perform an angle of arrival estimation for the target access node.

16 . A method according to claim 14 , wherein the value for the compensation parameter is obtained from a look-up table stored in the terminal device.

17 . A method according to claim 14 , wherein the value for the compensation parameter is obtained by utilizing a determined mapping function between an input and a corresponding output.

18 . A method according to claim 17 , wherein the input comprises at least one of the following: a beam index and/or an antenna array configuration; and wherein the output comprises the value for the compensation parameter.

19 . A method according to claim 14 , wherein the value for the compensation parameter is obtained by calculating it based on radiation patterns stored in the terminal device.

20 . A non-transitory computer readable medium comprising program instructions that, when executed by an apparatus, cause the apparatus to perform at least the following:

receive a positioning reference signal request;

determine positioning requirements associated with the received positioning reference signal request;

determine capabilities of a terminal device;

determine an antenna array radiation pattern beam width for a position reference signal based, at least partly on the determined positioning requirements and the determined capabilities of the terminal device;

obtain a value for a compensation parameter based on the determined antenna array radiation pattern beam width;

perform beam steering towards a target access node; and

perform a timing compensation using the compensation parameter with the obtained value.
