Abstract

The disclosure relates to an apparatus including circuitry for: selecting at least one covered user equipment among a plurality of covered user equipment inside the coverage area of the apparatus; sending, to the at least one covered user equipment, a searching message, wherein the searching message includes an indication that the at least one covered user equipment is to send a searching result message to the apparatus, wherein the searching result message includes an indication of at least one non-covered user equipment located outside the coverage area of the apparatus and inside a coverage area of the at least one covered user equipment; and receiving, from the at least one covered user equipment, the searching result message.

First claim

The invention claimed is:

1 . An apparatus, comprising:
at least one processor; and at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
selecting at least one covered user equipment among a plurality of covered user equipment inside a coverage area of the apparatus;
sending, to the at least one covered user equipment, a searching message, wherein the searching message comprises an indication that the at least one covered user equipment is to send a searching result message to the apparatus, wherein the searching result message comprises an indication of at least one non-covered user equipment located outside the coverage area of the apparatus and inside a coverage area of the at least one covered user equipment; and
receiving, from the at least one covered user equipment, the searching result message.

2 . The apparatus of claim 1 , wherein the at least one covered user equipment is at an edge of the coverage area of the apparatus.

3 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
identifying a list of covered user equipment and assigning a priority to the covered user equipment; and selecting at least one covered user equipment with a highest priority within the list.

4 . The apparatus of claim 3 , wherein the priority is determined based on at least one of a distance between the at least one covered user equipment and the apparatus or a quality of service between the at least one covered user equipment and the apparatus; and
wherein the at least one covered user equipment with the highest priority is the at least one covered user equipment with at least one of the longest distance between the at least one covered user equipment and the apparatus or the lowest quality of service above a threshold between the at least one covered user equipment and the apparatus.

5 . The apparatus of claim 3 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
selecting at least one subsequent covered user equipment with a subsequent highest priority within the list; sending, to the at least one subsequent covered user equipment, a searching message; and receiving, from the at least one subsequent covered user equipment, the searching result message; wherein the selecting, the sending, and the receiving are repeated until a condition is met.

6 . The apparatus of claim 5 , wherein the condition is that the non-covered user equipment has been indicated to the apparatus in at least one searching result message or the covered user equipment within the list has been selected.

7 . The apparatus of claim 3 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
receiving the list of covered user equipment from a network or an apparatus controller.

8 . The apparatus of claim 7 , wherein the covered user equipment has a priority determined with the apparatus or with the network or the apparatus controller.

9 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
identifying a list of covered user equipment, the covered user equipment having a same priority; and selecting at least one covered user equipment randomly within the list.

10 . The apparatus of claim 9 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
selecting at least one subsequent covered user equipment randomly within the list; sending, to the at least one subsequent covered user equipment, a searching message; and receiving, from the at least one subsequent covered user equipment, the searching result message; wherein the selecting, the sending, and the receiving are repeated until a condition is met.

11 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
identifying a plurality of lists of covered user equipment, the list having a different priority; selecting a list with a highest priority; and selecting at least one covered user equipment within the selected list.

12 . The apparatus of claim 11 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
selecting at least one subsequent covered user equipment within the selected list; sending, to the at least one subsequent covered user equipment, a searching message; and receiving, from the at least one subsequent covered user equipment, the searching result message; wherein the selecting, the sending, and the receiving are repeated until a condition is met.

13 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
receiving information indicating a radio resource to be used with the apparatus to send a searching message to the at least one covered user equipment.

14 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
receiving information indicating a beam to be used with the apparatus to send a searching message to the at least one covered user equipment.

15 . The apparatus of claim 1 , wherein the searching message is a unicast message.

16 . The apparatus of claim 1 , wherein the searching message is a multicast message or a broadcast message.

17 . The apparatus of claim 16 , wherein the multicast message or the broadcast message comprises information indicating at least one of the at least one covered user equipment or time instants for the at least one covered user equipment to send a discovery message to the at least one non-covered user equipment,
wherein the discovery message comprises an indication that the at least one non-covered user equipment is to send a discovery result message to the at least one covered user equipment; and wherein the discovery result message comprises an indication that the at least one non-covered user equipment received a discovery message.

18 . The apparatus of claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:
sending, to the at least one covered user equipment, a data relaying message, wherein the data relaying message comprises an indication that the at least one covered user equipment has been selected to relay data between the apparatus and the at least one non-covered user equipment.

19 . The apparatus of claim 1 , wherein the apparatus is a user equipment.

20 . The apparatus of claim 19 , wherein at least one of the user equipment or the at least one covered user equipment is an unmanned aerial vehicle.

21 . A method, comprising:
selecting at least one covered user equipment among a plurality of covered user equipment inside the coverage area of the apparatus; sending, to the at least one covered user equipment, a searching message, wherein the searching message comprises an indication that the at least one covered user equipment is to send a searching result message to the apparatus, wherein the searching result message comprises an indication of at least one non-covered user equipment located outside the coverage area of the apparatus and inside a coverage area of the at least one covered user equipment; and r
