RE: Active and Deep Sleep [per My action item]



Title: Message
Hello Yogesh,
 
It would be important for .21 to be power savvy/sensitive. However, we can't go so far as to specify the PHY behavior at the level you suggest can we? There are other options besides off/on for many of these parameters, and they vary from bearer type to bearer type. An abstraction that might let a mobility management entity on the MN query L2.5 about the power status in a media independent way could be useful but we need something more specific/comprehensive to the planned supported radio PHYs than just off/on.
 
This came up in 3GPP too, where they were trying to decide if power off could trigger release of security associations. Then people wondered what does power off mean. (This is another example why it would be so good if we were working with them right now.)
 
BR,
Michael

Vivek,
3.7 Power management
 
Wherever applicable the standard shall select network scanning opportunities to coincide with scheduled wake times to minimize the expended power by switching between the power save and active modes of operations for the wireless media employed.
 
Power Save Mode: The state in which a STA's transceiver is off in order to conserve power used during the active mode.
Precisely,
    Transceiver: OFF
    Internal Clocks: INACTIVE (except one low frequency clock)
    Peripherals: OFF
    Network Sync: OFF
 
Active Mode: The state in which a STA's transceiver is on in order to perform typical operations needed for operation within a wireless system.
Precisely,
 
    Transceiver: ON
    Internal Clocks: ACTIVE
    Peripherals: ON
    Network Sync: ON
