POWER SAVING IN A COMMUNICATION DEVICE
First Claim
1. A method in a communication network having an access point (AP) and a plurality of client devices, comprising:
- generating, at the AP, a physical layer (PHY) protocol header of a PHY protocol data unit so that the PHY protocol header includes;
address information that indicates one or more intended receivers of the PHY protocol data unit, andan indicator that specifies whether a client device that is not an intended receiver is permitted to go into a power save mode of operation during a transmit opportunity period (TXOP) associated with the PHY protocol data unit;
generating, at the AP, the PHY protocol data unit to includethe PHY protocol preamble, anda PHY protocol payload including a media access control layer (MAC) protocol header, the MAC protocol header including address information that specifies the one or more intended receivers of the PHY protocol data unit; and
causing the AP to transmit the PHY protocol data unit.

Abstract
In a communication network having an access point (AP) and a plurality of client devices, the AP generates a physical layer (PHY) protocol header of a PHY protocol data unit so that the PHY protocol header includes: address information that indicates one or more intended receivers of the PHY protocol data unit, and an indicator that specifies whether a client device that is not an intended receiver is permitted to go into a power save mode of operation during a transmit opportunity period (TXOP) associated with the PHY protocol data unit. The AP generates the PHY protocol data unit to include the PHY protocol preamble, and a PHY protocol payload including a media access control layer (MAC) protocol header, the MAC protocol header including address information that specifies the one or more intended receivers of the PHY protocol data unit. The AP transmits the PHY protocol data unit.

6. An apparatus for use in a communication network having an access point (AP) and a plurality of client devices, the apparatus comprising:
-
a network interface associated with the AP, the network interface having one or more integrated circuits configured to; generate a physical layer (PHY) protocol header of a PHY protocol data unit so that the PHY protocol header includes; address information that indicates one or more intended receivers of the PHY protocol data unit, and an indicator that specifies whether a client device that is not an intended receiver is permitted to go into a power save mode of operation during a transmit opportunity period (TXOP) associated with the PHY protocol data unit; wherein the one or more integrated circuits are further configured to; generate the PHY protocol data unit to include the PHY protocol preamble, and a PHY protocol payload including a media access control layer (MAC) protocol header, the MAC protocol header including address information that specifies the one or more intended receivers of the PHY protocol data unit; and cause the AP to transmit the PHY protocol data unit. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method in a communication network having an access point (AP) and a plurality of client devices, comprising:
-
receiving, at a communication device, a physical layer (PHY) protocol data unit from the AP, the PHY protocol data unit having a PHY protocol header, wherein the PHY protocol header includes; address information that indicates one or more intended receivers of the PHY protocol data unit, and an indicator that specifies whether a client device that is not an intended receiver is permitted to go into a power save mode of operation during a transmit opportunity period (TXOP) associated with the PHY protocol data unit; analyzing, at the communication device, the address information in the PHY protocol header to determine whether the communication device is an intended receiver of the PHY protocol data unit; in response to i) determining that the communication device is not an intended receiver of the PHY protocol data unit based on analyzing the address information in the PHY protocol header, and ii) determining, at the communication device, that the indicator in the PHY protocol header specifies that a client device that is not an intended receiver is permitted to go into the power save mode of operation during the TXOP associated with the PHY protocol data unit, entering, at the communication device, the power save mode of operation during the TXOP; and in response to i) determining that the communication device is not an intended receiver of the PHY protocol data unit based on analyzing the address information in the PHY protocol header, and ii) determining, at the communication device, that the indicator in the PHY protocol header specifies that a client device that is not an intended receiver is not permitted to go into the power save mode of operation during the TXOP associated with the PHY protocol data unit, not entering, at the communication device, the power save mode of operation during the TXOP. - View Dependent Claims (14, 15, 16, 17)
