Abstract

There is disclosed a method comprising: receiving priority information indicative of a priority state of at least one positioning reference signal, receiving time window information configuring a time window that is outside of a measurement gap; and based on the priority information and the time window information, receiving one or more positioning reference signals during the time window by using one or more buffer symbols.

First claim

The invention claimed is:

1 . An apparatus comprising:
at least one processor; and at least one memory including instructions stored therein that, when executed by the at least one processor, cause the apparatus to perform at least:
receiving priority information indicative of a priority state of one or more positioning reference signals (PRSs);
receiving time window information configuring a PRS processing window that is outside of a measurement gap; and
receiving, based on the priority information and the time window information, one or more PRSs during the PRS processing window after one or more symbols,
wherein the one or more symbols are positioned prior to the one or more PRS symbols configured for the one or more PRSs within the PRS processing window, or wherein the one or more symbols are positioned before a start of the PRS processing window.

2 . The apparatus of claim 1 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the apparatus to perform:
receiving a configuration for the one or more symbols.

3 . The apparatus of claim 2 , wherein the one or more symbols are based on the received configuration for the one or more symbols.

4 . The apparatus of claim 1 , wherein the one or more symbols are used to perform beam switching for reception of the one or more PRSs or to process received downlink control information.

5 . The apparatus of claim 1 , wherein the priority information indicates one of: a first priority state, a second priority state, or a third priority state.

6 . The apparatus of claim 5 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the apparatus to perform:
in an instance in which the priority information indicates the first priority state, prioritizing the one or more PRSs relative to a physical downlink shared channel such that, for at least part of the PRS processing window, the physical downlink shared channel is dropped in favor of the one or more PRSs.

7 . The apparatus of claim 5 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the apparatus to perform:
in an instance in which the priority information indicates the second priority state, prioritizing low latency traffic on a physical downlink shared channel relative to the one or more PRSs.

8 . The apparatus of claim 5 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the apparatus to perform:
in an instance in which the priority information indicates the second priority state, dropping at least one of the one or more PRSs in favor of at least one of the one or more symbols.

9 . The apparatus of claim 5 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the apparatus to perform:
in an instance in which the priority information indicates the third priority state, considering the one or more PRSs as lower priority than one or more of: a physical downlink control channel or a physical downlink shared channel.

10 . A method comprising:
receiving priority information indicative of a priority state of one or more positioning reference signals (PRSs); receiving time window information configuring a PRS processing window that is outside of a measurement gap; and receiving, based on the priority information and the time window information, one or more PRSs during the PRS processing window after one or more symbols, wherein the one or more symbols are positioned prior to one or more PRS symbols configured for the one or more PRSs within the PRS processing window, or wherein the one or more symbols are positioned before a start of the PRS processing window.

11 . The method of claim 10 , further comprising:
receiving a configuration for the one or more symbols.

12 . The method of claim 11 , wherein the one or more symbols are based on the received configuration for the one or more symbols.

13 . The method of claim 10 , wherein the one or more symbols are used to perform beam switching for reception of the one or more PRSs or to process received downlink control information.

14 . The method of claim 10 , wherein the priority information indicates one of: a first priority state, a second priority state, or a third priority state.

15 . The method of claim 14 , further comprising:
in an instance in which the priority information indicates the first priority state, prioritizing the one or more PRSs relative to a physical downlink shared channel such that, for at least part of the PRS processing window, the physical downlink shared channel is dropped in favor of the one or more PRSs.

16 . The method of claim 14 , further comprising:
in an instance in which the priority information indicates the second priority state, prioritizing low latency traffic on a physical downlink shared channel relative to the one or more PRSs.

17 . The method of claim 14 , further comprising:
in an instance in which the priority information indicates the second priority state, dropping at least one of the one or more PRSs in favor of at least one of the one or more symbols.

18 . The method of claim 14 , further comprising:
in an instance in which the priority information indicates the third priority state, considering the one or more PRSs as lower priority than one or more of: a physical downlink control channel or a physical downlink shared channel.

19 . A non-transitory computer-readable storage medium comprising instructions stored therein that, when executed by at least one processor of an apparatus, cause the apparatus to perform at least:
receiving priority information indicative of a priority state of one or more positioning reference signals (PRSs); receiving time window information configuring a PRS processing window that is outside of a measurement gap; and receiving, based on the priority information and the time window information, one or more PRSs during the PRS processing window after one or more symbols, wherein the one or more symbols are positioned prior to one or more PRS symbols configured for the one or more PRSs within the PRS processing window, or wherein the one or more symbols are positioned before a start of the PRS processing window.

20 . An apparatus comprising:
at least one processor; and at least one memory comprising instructions stored therein that, when executed by the at least one processor, cause the apparatus to perform at least:
sending, to a user device, priority information indicative of a priority state of one or more positioning reference signals (PRSs);
sending, to the user device, time window information for configuring a PRS processing window that is outside of a measurement gap; and
sending a symbol configuration to the user device, the symbol configuration for use by the user device in receiving one or more PRSs during the PRS processing window after one or more symbols,
wherein the one or more symbols are positioned prior to one or more PRS symbols configured for the one or more PRSs within the PRS processing window, or
wherein the one or more symbols are positioned before a start of the PRS processing window.

21 . The apparatus of claim 20 , wherein the instructions stored in the at least one memory, when executed by the at least one processor, further cause the appara
