Abstract

The present application relates to a method and an apparatus for path reporting. One embodiment of the subject application provides a method performed by a primary user equipment (UE) in a UE group, comprising: receiving one or more secondary path reports, each including a secondary path of a corresponding secondary UE in the UE group; determining a group path report based on a primary path of the primary UE and/or the one or more secondary paths; and transmitting the group path report to a Base Station (BS).

First claim

We claim:

1 . A primary user equipment (UE) in a UE group for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the primary UE to: receive one or more secondary path reports and one or more indicators from one or more secondary UEs in the UE group, each secondary path report including a secondary path of a corresponding secondary UE in the UE group, and the one or more indicators indicating at least one radio connection condition between the one or more secondary UEs and a Base Station (BS) is below a threshold; determine a group path report based on one or more of a primary path of the primary UE or the one or more secondary paths; and transmit the group path report to the BS.

2 . The primary UE of claim 1 , wherein the at least one processor is operable to cause the primary UE to:
transmit one or more of a path report configuration or a path report request to one or more secondary UEs in the UE group, wherein the one or more of the path report configuration or the path report request is received from the BS or is determined by the primary UE.

3 . The primary UE of claim 2 , wherein the one or more of the path report configuration or the path report request includes one or more of a location requirement or a propagation delay requirement.

4 . The primary UE of claim 2 , wherein the one or more of the path report configuration or the path report request includes at least one of:
a path report type; a UE group identity; a total number of UEs which are required to transmit path reports; or one or more identities of UEs which are required to transmit path reports.

5 . The primary UE of claim 1 , wherein the group path report comprises the one or more of the primary path or the one or more secondary paths.

6 . The primary UE of claim 1 , wherein the group path report comprises one or more of a common path or a reference path for the UE group based on the one or more of the primary path of the primary UE or the one or more secondary paths.

7 . The primary UE of claim 1 , wherein the at least one processor is operable to cause the primary UE to transmit the group path report when one or more of:
a new UE joins the UE group; a UE leaves the UE group; a new path configuration is assigned to the UE group; a path report from a secondary UE other than the one or more secondary UEs in the UE group is received; or a total number of secondary path reports is over a threshold.

8 . The primary UE of claim 1 , wherein the at least one processor is operable to cause the primary UE to receive the one or more secondary path reports via a sidelink between the primary UE and corresponding one or more secondary UEs.

9 . The primary UE of claim 1 , wherein the group path report includes at least one of:
parameters indicated in a group path report configuration or a group path report request; location information of waypoints; time information of waypoints; Quality of Service (QOS) requirement; Quality of Experience (QoE) requirement; or network slice of a path.

10 . A secondary user equipment (UE) in a UE group for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the secondary UE to: determine a destination between a primary UE and a Base Station (BS) based on comparing one or more of:
a radio connection condition between the secondary UE and the BS;
a radio connection condition between the secondary UE and the primary UE; or
one or more thresholds; and
transmit a secondary path report to the destination.

11 . The secondary UE of claim 10 , wherein the at least one processor is operable to cause the secondary UE to:
transmit the secondary path report to the BS when one or more of a distance or a propagation delay between the secondary UE and the BS is smaller than a threshold.

12 . The secondary UE of claim 10 , wherein the at least one processor is operable to cause the secondary UE to:
transmit the secondary path report to the BS when a link quality between the secondary UE and the primary UE is lower than a threshold.

13 . The secondary UE of claim 10 , wherein the at least one processor is operable to cause the secondary UE apparatus to:
transmit the secondary path report to the primary UE when one or more of a distance or a propagation delay between the secondary UE and the primary UE is smaller than a threshold, or when the one or more of the distance or the propagation delay between the secondary UE and the primary UE is smaller than one or more of a distance or a propagation delay between the secondary UE and the BS.

14 . The secondary UE of claim 10 , wherein the at least one processor is operable to cause the secondary UE to:
transmit the secondary path report to the primary UE when one or more of a link quality between the secondary UE and the BS is lower than a threshold, or when the link quality between the secondary UE and the BS is lower than a link quality between the secondary UE and the primary UE.

15 . The secondary UE of claim 10 , wherein the at least one processor is operable to cause the secondary UE to:
receive a path report configuration or a path report request from the BS or from the primary UE.

16 . A method performed by a primary user equipment (UE) in a UE group, the method comprising:
receiving one or more secondary path reports and one or more indicators from one or more secondary UEs in the UE group, each secondary path report including a secondary path of a corresponding secondary UE in the UE group, and the one or more indicators indicating at least one radio connection condition between the one or more secondary UEs and a Base Station (BS) is below a threshold; determining a group path report based on one or more of a primary path of the primary UE or the one or more secondary paths; and transmitting the group path report to the BS.

17 . The method of claim 16 , further comprising:
transmitting one or more of a path report configuration or a path report request to one or more secondary UEs in the UE group, wherein the one or more of the path report configuration or the path report request is received from the BS or is determined by the primary UE.

18 . The method of claim 17 , wherein the one or more of the path report configuration or the path report request includes one or more of a location requirement or a propagation delay requirement.

19 . The method of claim 16 , wherein the group path report comprises one or more of the primary path or the one or more secondary paths.

20 . The method of claim 16 , wherein the group path report comprises one or more of a common path or a reference path for the UE group based on one or more of the primary path of the primary UE or one or more secondary paths.
