in response to determining that the receiver identity in the wake-up trigger frame is the group receiver identity, comparing the group receiver identity with a whitelist or a blacklist, wherein the whitelist comprises a plurality of groupcast addresses that the device intends to wake up for, and the blacklist comprises a plurality of groupcast addresses that the device does not want to wake up for; and
in response to determining that the group receiver identity matches to one of the plurality of groupcast addresses in the whitelist, sending a signal to a primary radio of the device to turn on the primary radio.

6. The method of claim 1 , wherein the group receiver identity has a same length as an association identifier (AID).
7. The method of claim 1 , wherein the access point maintains a list of group receiver identities, wherein the device is associated with one or more group receiver identities from the list of group receiver identities, and the device receives the one or more group receiver identities from the access point.
8. The method of claim 1 , wherein the wake-up trigger frame further includes a source address identifying a node sending data to the device.
9. The method of claim 8 , wherein the source address is a MAC address.
10. The method of claim 8 , wherein the source address is included in at least one of a payload field of the wake-up trigger frame or a header of the wake-up trigger frame.
11. The method of claim 8 , the method further comprising:
based on the source address, determining whether to send the signal to turn on the primary radio.
12. The method of claim 1 , wherein the wake-up trigger frame further includes a transmitter identity, and the method further comprises:
based on the transmitter identity, determining whether to send the signal to turn on the primary radio.
13. The method of claim 1 , further comprising, in response to determining that the group receiver identity matches to the blacklist, refraining from sending a signal to the primary radio of the device to turn on the primary radio.
14. A device, comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to:
receive, at a wake-up radio of the device and from an access point, a wake-up trigger frame, wherein the wake-up trigger frame includes a receiver identity;
determine whether the receiver identity in the wake-up trigger frame is a unicast receiver identity or a group receiver identity based on an identifier in the receiver identity in the wake-up trigger frame;
in response to determining that the identifier in the receiver identity in the wake-up trigger frame corresponds to groupcast, determine that the receiver identity in the wake-up trigger frame is the group receiver identity;
in response to determining that the receiver identity in the wake-up trigger frame is the group receiver identity, compare the group receiver identity with a whitelist or a blacklist, wherein the whitelist comprises a plurality of groupcast addresses that the device intends to wake up for, and the blacklist comprises a plurality of groupcast addresses that the device does not want to wake up for; and
in response to determining that the group receiver identity matches to one of the plurality of groupcast addresses in the whitelist, send a signal to a primary radio of the device to turn on the primary radio.
15. The device of claim 14 , wherein the access point is an IEEE 802.11 access point, the device is an IEEE 802.11 device, the wake-up radio includes receiving functionalities, and the primary radio includes both transmitting and receiving functionalities.
16. The device of claim 14 , wherein the group receiver identity is used for at least one of multicast or broadcast, and the group receiver identity has a same length as an association identifier (AID).
17. The device of claim 14 , wherein the wake-up trigger frame further includes a source address identifying a node sending data to the device, and the at least one hardware processor is further configured to determine whether to send the signal to turn on the primary radio based on the source address.
18. A non-transitory computer-readable medium containing instructions which, when executed, cause a device to perform operations comprising:
receiving, at a wake-up radio of the device and from an access point, a wake-up trigger frame, wherein the wake-up trigger frame includes a receiver identity;
determining whether the receiver identity in the wake-up trigger frame is a unicast receiver identity or a group receiver identity based on an identifier in the receiver identity in the wake-up trigger frame;
in response to determining that the identifier in the receiver identity in the wake-up trigger frame corresponds to groupcast, determining that the receiver identity in the wake-up trigger frame is the group receiver identity;
in response to determining that the receiver identity in the wake-up trigger frame is the group receiver identity, comparing the group receiver identity with a whitelist or a blacklist, wherein the whitelist comprises a plurality of groupcast addresses that the device intends to wake up for, and the blacklist comprises a plurality of groupcast addresses that the device does not want to wake up for; and
in response to determining that the group receiver identity matches to one of the plurality of groupcast addresses in the whitelist, sending a signal to a primary radio of the device to turn on the primary radio.
