1. An apparatus, comprising a wireless communications device adapted to:
- receive at least a portion of a packet containing multiple groups of addressed frames directed to different addresses, each group containing adjacent frames addressed to a same address, the packet further containing a list of the addresses in order of transmission of the groups within the packet;
determine, based on the list, which address is identified with a last of the multiple groups to be transmitted in which the wireless communications device has an interest; and
transition to a low-power mode for a substantial remainder of the packet after receiving the last of the multiple groups in which the wireless communications device has an interest.

Abstract
In a communications packet directed to multiple addresses and having a directory of the addresses in order of transmission, a device receiving the packet may use the directory to help determine when the last frame in which the device has an interest is received, and then enter a low power mode for the remainder of the packet reception. The device constructing the packet for transmission may arrange the frames in a manner that promotes overall power savings in the group of addressed devices.

8. A method, comprising:
-
receiving, in a wireless communications device, at least a portion of a packet comprising a directory structure followed by multiple addressed frames organized in groups of frames with like addresses, the directory structure containing a list of addresses of the addressed frames in an order the groups are to be received;
determining, from the list of addresses and from monitoring received frames, which of the multiple addressed frames is a last frame in which the wireless communications device has an interest; and
placing the wireless communications device in a low power mode after receiving the last frame in which the wireless communications device has an interest, but before an end of the packet. - View Dependent Claims (9, 10)

11. An article comprising
a machine-readable medium that provides instructions, which when executed by a computing platform, cause said computing platform to perform operations comprising: -
receiving, in a wireless communications device, at least a portion of a packet comprising a directory structure followed by multiple addressed frames, the directory structure containing a list of addresses of the addressed frames in an order the addressed frames are to be received;
determining which of the multiple addressed frames is a last frame addressed to the wireless communications device; and
placing the wireless communications device in a low power mode after receiving the last frame addressed to the wireless communications device. - View Dependent Claims (12, 13)

14. An apparatus, comprising
a wireless communications device adapted to construct a packet containing a directory structure followed by multiple addressed frames, the multiple addressed frames organized into groups containing like addresses, the directory structure containing a list of addresses in the addressed frames in an order the groups are to be transmitted.

19. A method, comprising:
-
constructing a packet containing a directory structure followed by multiple addressed frames, the directory structure containing a list of addresses in the addressed frames in an order the addressed frames are to be transmitted;
wherein the addressed frames comprise a multicast section of frames and a unicast section of frames, the multicast section to be transmitted before the unicast section;
wherein each address in the list of addresses appears only once in the directory structure, and addressed frames are organized into groups of adjacent frames with a same address. - View Dependent Claims (20, 21, 22)
