Abstract
After waking from a sleep mode, a wireless communication device may poll a network controller for any broadcast and/or multicast messages. The device and the network controller may agree to this arrangement ahead of time, so that the network controller will know to buffer such messages until the device requests them. A format for enabling this capability is described.
Claims25
A network controller, comprising:
- processing circuitry;
- and
- logic, at least a portion of which is in hardware, the logic to send a first notification indicating that the network controller supports group-addressed polling, receive a second notification indicating that a subscriber station (SS) is to use group-addressed polling, buffer a group-addressed packet in response to a determination that the group-addressed packet is addressed to a multicast group (MCG) that comprises the SS and a determination that the SS is in a sleep state, and send the group-addressed packet while the SS is in the sleep state.
At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed at a network controller, cause the network controller to:
- transmit a first notification indicating that the network controller supports group-addressed polling;
- receive a second notification indicating that a subscriber station (SS) is to use group-addressed polling;
- buffer a group-addressed packet in response to a determination that the group-addressed packet is addressed to a multicast group (MCG) that comprises the SS and a determination that the SS is in a sleep state;
- and
- transmit the group-addressed packet while the SS is in the sleep state.
2 more elements
A method, comprising:
- transmitting, by one or more antennas of a network controller (NC), a first notification indicating that the NC supports group-addressed polling;
- receiving a second notification indicating that a subscriber station (SS) is to use group-addressed polling;
- buffering a group-addressed packet in response to a determination that the group-addressed packet is addressed to a multicast group (MCG) that comprises the SS and a determination that the SS is in a sleep state;
- and
- transmitting the group-addressed packet while the SS is in the sleep state.
