form a link with an AP; and

receive information associated with emergency preparedness communication services (EPCS) from the AP; and

a processor operably coupled to the transceiver, the processor configured to:

based on the received information, determine whether the STA and the AP support an EPCS operation;

based on determining that the STA and the AP support the EPCS operation, determine whether the AP supports prioritization for EPCS devices that are authorized by the AP to use the EPCS;

when the AP does not support prioritization for the EPCS devices, perform the EPCS operation using an enhanced distributed channel access (EDCA) parameter set; and

when the AP supports prioritization for EPCS devices, perform a prioritized EPCS operation using an enhanced EDCA parameter set based on a priority level for the STA included in the received information, wherein the priority level indicates a priority for performing the EPCS among the authorized EPCS devices.

transmit, to the AP, a request for a priority level change; and

receive, from the AP, a response to the request for a priority level change.

5 . The non-AP device of claim 2 , wherein the transceiver is configured to:

transmit, to the AP, information associated with a mode that the STA is running or intends to run; and

receive an indication associated with the priority level for the STA from the AP based on the information associated with the mode that the STA is running or intends to run.

6 . The non-AP device of claim 2 , wherein the transceiver is configured to:

transmit, to the AP, information associated with link prioritization for the STA; and

receive an indication associated with the priority level for the STA from the AP based on the information associated with the link prioritization for the STA.

7 . The non-AP device of claim 2 , wherein the priority level for the STA is based on a service type.

8 . The non-AP device of claim 7 , wherein the transceiver is configured to:

transmit, to the AP, information associated with a service type that the STA is running or intends to run; and

receive an indication associated with the priority level for the STA from the AP based on the information associated with the service type that the STA is running or intends to run.

9 . An access point (AP) device comprising:

a transceiver configured to:

form a link with a station (STA), and

transmit information associated with emergency preparedness communication services (EPCS) to the STA; and

a processor operably coupled to the transceiver, the processor configured to:

based on the transmitted information, determine whether the AP and the STA support an EPCS operation;

based on determining that the AP and the STA support the EPCS operation, determine whether the AP supports prioritization for EPCS devices authorized by the AP to use the EPCS;

when the AP does not support prioritization for the EPCS devices, perform the EPCS operation using an enhanced distributed channel access (EDCA) parameter set; and

when the AP supports prioritization for EPCS devices, perform a prioritized EPCS operation using an enhanced EDCA parameter set based on a priority level for the STA included in the transmitted information, wherein the priority level indicates a priority for performing the EPCS among the authorized EPCS devices.

10 . The AP device of claim 9 , wherein:

the AP supports prioritization for the EPCS devices,

the processor is configured to determine the priority level for the STA, and

the transceiver is configured to transmit the priority level for the STA.

11 . The AP device of claim 10 , wherein the transceiver is further configured to:

receive, from the STA, information associated with a mode that the STA is running or intends to run; and

transmit an indication associated with the priority level for the STA based on the information associated with the mode that the STA is running or intends to run.

12 . The AP device of claim 10 , wherein:

the priority level for the STA is based on a service type, and

the transceiver is further configured to:

receive, from the STA, information associated with the service type that the STA is running or intends to run; and

transmit an indication associated with the priority level for the STA based on the information associated with the service type that the STA is running or intends to run.

13 . A method for wireless communication performed by a non-access point (AP) device that comprises a station (STA), the method comprising:

forming a link with an AP;

receiving information associated with emergency preparedness communication services (EPCS) from the AP;

based on the received information, determining whether the STA and the AP support an EPCS operation;

based on determining that the STA and the AP support the EPCS operation, determining whether the AP supports prioritization for EPCS devices authorized by the AP to use the EPCS;

when the AP does not support prioritization for EPCS devices, performing the EPCS operation using an enhanced distributed channel access (EDCA) parameter set; and

when the AP supports prioritization for the EPCS devices, performing a prioritized EPCS operation using an enhanced EDCA parameter set based on a priority level for the STA included in the received information, wherein the priority level indicates a priority for performing the EPCS among the authorized EPCS devices.

14 . The method of claim 13 , wherein:

the AP supports prioritization for the EPCS devices, and

the method further comprises identifying the priority level for the STA.

15 . The method of claim 14 , wherein the priority level for the STA is based on a device identification.
