Abstract

In an embodiment, a node (e.g., a UE, BS or relay node) transmits a paging message including at least one reference value associated with an event. At least one UE responds to the paging message (e.g., based on the presence of the at least one reference value in the paging message) with a response including UE-identifying information and the at least one reference value associated with the event. In an example where the node is a relay node, the relay node may coordinate with a BS so as to obtain an allocation of paging resources for transmission of the paging message. In a further embodiment, a UE may transmit, to a BS, at least one Message-A comprised by a PUSCH of a 2-Step RACH procedure, wherein the Message-A includes the at least one reference value associated with the event.

First claim

What is claimed is:

1. A method of wireless communications by a node, comprising:
transmitting a paging message including at least one reference value associated with an event that is detected as being in progress in a target geographical area; and
receiving a set of responses to the paging message from a set of UEs including at least one UE, each response comprising UE-identifying information and the at least one reference value associated with the event.

2. The method of claim 1 , further comprising:
transmitting, from the node to a wireless network component, at least one Message-A comprised by a PUSCH of a 2-Step RACH procedure, wherein the Message-A includes the at least one reference value associated with the event.

3. The method of claim 1 , wherein the at least one reference value comprises a time value or a range of time values, location information, an event index value, or a combination thereof.

4. The method of claim 1 , wherein the node is a user equipment or a relay node.

5. The method of claim 1 , wherein the node is a wireless network component.

6. The method of claim 1 ,
wherein the node is a relay node, further comprising:
sending, to a wireless network component, a request for paging resources;
receiving, from the wireless network component, an allocation of a set of paging resources including at least one paging resource in response to the request,
wherein the paging message is transmitted over the set of paging resources.

7. The method of claim 6 ,
wherein the request specifies at least one preferred signal synchronization block (SSB) index,
wherein the allocated set of paging resources comprises at least one SSB index, and
wherein the paging message is transmitted via the allocated at least one SSB index.

8. The method of claim 6 ,
wherein the request is sent via radio resource control (RRC) signaling, medium access control (MAC)-command element (CE) signaling, or uplink control information (UCI) signaling, and
wherein the allocation of the set of paging resources is received via RRC signaling, MAC-CE signaling, or downlink control information (DCI) signaling.

9. The method of claim 6 , wherein the at least one reference value comprises a time value or a range of time values, location information, an event index value, or a combination thereof.

10. A method of wireless communication by a user equipment (UE), comprising:
receiving, from a node, a paging message including at least one reference value associated with an event that is detected as being in progress in a target geographical area;
determining to respond to the paging message based at least in part upon the presence at least one reference value within the paging message; and
transmitting a response to the paging message, the response comprising UE-identifying information and the at least one reference value.

11. The method of claim 10 , wherein the determining determines to respond to the paging message based at least in part upon the presence at least one reference value within the paging message irrespective of whether the paging message includes information identifying the UE or information identifying a group to which the UE belongs.

12. The method of claim 10 , wherein the node is another UE, a wireless network component, or a relay node.

13. The method of claim 10 , wherein the at least one reference value comprises a time value or a range of time values, location information, an event index value, or a combination thereof.

14. A method of wireless communications by a user equipment (UE), comprising:
determining at least one reference value associated with an event; and
transmitting, from the UE to a wireless network component, at least one Message-A comprised by a Physical Uplink Shared Channel (PUSCH) of a 2-Step Random Access Channel (RACH) procedure, wherein the Message-A includes the at least one reference value associated with the event.

15. The method of claim 14 , wherein the at least one reference value comprises a time value or a range of time values, location information, an event index value, or a combination thereof.

16. A method of wireless communications by a wireless network component, comprising:
receiving, from a user equipment (UE), at least one Message-A comprised by a Physical Uplink Shared Channel (PUSCH) of a 2-Step Random Access Channel (RACH) procedure, wherein the Message-A includes the at least one reference value associated with an event; and
performing at least one action related to the event based on the at least one reference value.

17. The method of claim 16 , wherein the at least one reference value comprises a time value or a range of time values, location information, an event index value, or a combination thereof.

18. A method of wireless communication by a wireless network component, comprising:
receiving, from a relay node, a request for paging resources;
determining an allocation of a set of paging resources including at least one paging resource to the relay node in response to the request; and
transmitting an indication of the allocated set of paging resources to the relay node,
wherein the wireless network component is precluded from transmission of any paging messages on the allocated set of paging resources,
wherein the request specifies at least one preferred signal synchronization block (SSB) index,
wherein the allocated set of paging resources comprises at least one SSB index.

19. The method of claim 18 ,
wherein the request is received via radio resource control (RRC) signaling, medium access control (MAC)-command element (CE) signaling, or uplink control information (UCI) signaling, and
wherein the indication of the allocation of the set of paging resources is transmitted via RRC signaling, MAC-CE signaling, or downlink control information (DCI) signaling.

20. A node, comprising:
means for transmitting a paging message including at least one reference value associated with an event that is detected as being in progress in a target geographical area; and
means for receiving a set of responses to the paging message from a set of UEs including at least one UE, each response comprising UE-identifying information and the at least one reference value associated with the event.

21. A user equipment (UE), comprising:
means for receiving, from a node, a paging message including at least one reference value associated with an event that is detected as being in progress in a target geographical area;
means for determining to respond to the paging message based at least in part upon the presence at least one reference value within the paging message; and
means for transmitting a response to the paging message, the response comprising UE-identifying information and the at least one reference value.

22. A user equipment (UE), comprising:
means for determining at least one reference value associated with an event; and
means for transmitting, from the UE to a wireless network component, at least one Message-A comprised by a Physical Uplink Shared Channel (PUSCH) of a 2-Step Random Access Channel (RACH) procedure, wherein the Message-A includes the at least one reference value associated with the event.

23. A wireless network component, comprising:
means for receiving, from a user equipment (UE), at least one Message-A comprised by a Physical Uplink Shared Channel (PUSCH) of a 2-Step Random Access Channel (RACH) procedure, wherein the Message-A includes the at least one reference value assoc
