Abstract

A method performed by a wireless device operating in a wireless network. The method includes receiving a wake-up receiver frame, wherein the wake-up receiver frame includes a continuous frame field that indicates whether a further wake-up receiver frame comes after the wake-up receiver frame and determining whether the further wake-up receiver frame exists based on a content of the continuous frame field.

First claim

What is claimed is:

1 . A method performed by a wireless device operating in a wireless network, the method comprising:
receiving a wake-up receiver frame, wherein the wake-up receiver frame includes a continuous frame field that indicates whether a further wake-up receiver frame comes after the wake-up receiver frame; and determining whether the further wake-up receiver frame exists based on a content of the continuous frame field.

2 . The method of claim 1 , wherein the continuous frame field is included in a frame control field of the wake-up receiver frame.

3 . The method of claim 1 , further comprising:
determining whether an identifier indicated by an identifier field of the wake-up receiver frame matches an identifier of the wireless device.

4 . The method of claim 3 , wherein the identifier field is a foremost field of the wake-up receiver frame.

5 . The method of claim 4 , wherein the identifier field occupies bits B 0 to B 17 of the wake-up receiver frame.

6 . The method of claim 3 , further comprising:
transitioning to a wake-up receiver doze state in response to a determination that the identifier indicated by the identifier field of the wake-up receiver frame does not match the identifier of the wireless device and the further wake-up receiver frame does not exist.

7 . The method of claim 3 , further comprising:
processing the wake-up receiver frame in response to a determination that the identifier indicated by the identifier field of the wake-up receiver frame matches the identifier of the wireless device.

8 . The method of claim 7 , further comprising:
transitioning to a wake-up receiver doze state after processing the wake-up receiver frame in response to a determination that the further wake-up receiver frame does not exist.

9 . The method of claim 7 , further comprising:
determining whether the wake-up receiver frame has an error based on a frame check sequence (FCS) indicated by a FCS field of the wake-up receiver frame.

10 . The method of claim 9 , further comprising:
transitioning to a wake-up receiver doze state after processing the wake-up receiver frame in response to a determination that the wake-up receiver frame has the error despite a determination that the further wake-up receiver frame exists.

11 . The method of claim 9 , further comprising:
decoding the further wake-up receiver frame in response to a determination that the wake-up receiver frame does not have an error and a determination that the further wake-up receiver frame exists.

12 . The method of claim 1 , wherein the wake-up receiver frame is a wake-up receiver beacon frame.

13 . The method of claim 1 , wherein the wake-up receiver frame is a wake-up receiver wake-up frame.

14 . The method of claim 13 , wherein the wake-up receiver frame includes a frame body field, wherein the frame body field indicates identifiers of a plurality of wireless devices that are to be woken up.

15 . The method of claim 1 , wherein the wake-up receiver frame is a wake-up receiver data wake-up frame.

16 . The method of claim 1 , wherein the wake-up receiver frame includes a subtype field and a frame body field, wherein the frame body field includes data intended for the wireless device and the subtype field indicates a type of the data included in the frame body field.

17 . A wireless device that is to operate in a wireless network, the wireless device comprising:
a radio frequency transceiver; a memory device storing a set of instructions; and a processor coupled to the memory device, wherein the set of instructions when executed by the processor causes the wireless device to:
receive a wake-up receiver frame, wherein the wake-up receiver frame includes a continuous frame field that indicates whether a further wake-up receiver frame comes after the wake-up receiver frame and
determine whether the further wake-up receiver frame exists based on a content of the continuous frame field.

18 . The wireless device of claim 17 , wherein the continuous frame field is included in a frame control field of the wake-up receiver frame.

19 . The wireless device of claim 17 , wherein the set of instructions when executed by the processor further causes the wireless device to:
determine whether an identifier indicated by an identifier field of the wake-up receiver frame matches an identifier of the wireless device.

20 . The wireless device of claim 19 , wherein the identifier field is a foremost field of the wake-up receiver frame.
