Abstract

Various methods and devices are provided to address the need for improved multicast operation. In one method, a mobile device receives a multicast packet from a station, the mobile device being one of a plurality of mobile devices that includes a group of feedback mobile devices. The mobile device transmits an indication that it is volunteering to become a member of the group of feedback mobile devices and determines whether to begin operating as a member of the group of feedback mobile devices. If the mobile device is to begin operating as a member of the group of feedback mobile devices, the mobile device transmits an indication of channel quality and/or a level of interference observed by the mobile device.

Claims (38)

1. A method for improved multicast service using feedback mobiles, the method comprising:

receiving by a mobile device a multicast packet from a station, the mobile device being one of a plurality of mobile devices that includes a group of feedback mobile devices;

transmitting by the mobile device an indication that the mobile device is volunteering to become a member of the group of feedback mobile devices;

determining by the mobile device whether to begin operating as a member of the group of feedback mobile devices;

if the mobile device is to begin operating as a member of the group of feedback mobile devices, transmitting an indication of at least one of channel quality and a level of interference observed by the mobile device;

wherein the method further comprises:

receiving by the mobile device an indication of location and channel quality of the mobile devices included in the group of feedback mobile devices and

prior to transmitting the indication that the mobile device is volunteering, determining by the mobile device that no members of the group of feedback mobile devices are within a predefined adjacency distance from the mobile device.

2. The method of claim 1 , wherein determining whether to begin operating as a member of the group of feedback mobile devices comprises

receiving by the mobile device an indication that the mobile device has been added to the group of feedback mobile devices.

3. A method for improved multicast service using feedback mobiles, the method comprising:

receiving by a mobile device a multicast packet from a station, the mobile device being one of a plurality of mobile devices that includes a group of feedback mobile devices;

transmitting by the mobile device an indication that the mobile device is volunteering to become a member of the group of feedback mobile devices;

determining by the mobile device whether to begin operating as a member of the group of feedback mobile devices;

if the mobile device is to begin operating as a member of the group of feedback mobile devices, transmitting an indication of at least one of channel quality and a level of interference observed by the mobile device;

wherein the method further comprises:

receiving by the mobile device an indication of channel quality from the mobile devices included in the group of feedback mobile devices and

prior to transmitting the indication that the mobile device is volunteering, determining by the mobile device that no members of the group of feedback mobile devices are adjacent the mobile device and have a lower channel quality.

4. The method of claim 3 , wherein determining whether to begin operating as a member of the group of feedback mobile devices comprises

monitoring by the mobile device for any indications that another mobile device having a lower channel quality is volunteering or operating as a member of the group of feedback mobile devices.

5. An article of manufacture comprising a non-transitory, processor-readable storage medium storing one or more software programs which when executed by one or more processors performs the steps of the method of claim 1 .

6. A mobile device of a communication system, the mobile device being configured to communicate with other devices in the system using a mobile device transmitter and a mobile device receiver and being one of a plurality of mobile devices that includes a group of feedback mobile devices, wherein the mobile device is operative

to receive using the mobile device receiver a multicast packet from a station,

to transmit using the mobile device transmitter an indication that the mobile device is volunteering to become a member of the group of feedback mobile devices,

to determine whether to begin operating as a member of the group of feedback mobile devices, and

if the mobile device is to begin operating as a member of the group of feedback mobile devices, to transmit using the mobile device transmitter an indication of at least one of channel quality and a level of interference observed by the mobile device,

wherein the mobile device is further operative:

to receive using the mobile device receiver an indication of location and channel quality of the mobile devices included in the group of feedback mobile devices and

to determine, prior to transmitting the indication that the mobile device is volunteering, that no members of the group of feedback mobile devices are within a predefined adjacency distance from the mobile device.

7. A mobile device of a communication system, the mobile device being configured to communicate with other devices in the system using a mobile device transmitter and a mobile device receiver and being one of a plurality of mobile devices that includes a group of feedback mobile devices, wherein the mobile device is operative

to receive using the mobile device receiver a multicast packet from a station,

to transmit using the mobile device transmitter an indication that the mobile device is volunteering to become a member of the group of feedback mobile devices,

to determine whether to begin operating as a member of the group of feedback mobile devices, and

if the mobile device is to begin operating as a member of the group of feedback mobile devices, to transmit using the mobile device transmitter an indication of at least one of channel quality and a level of interference observed by the mobile device,

wherein the mobile device is further operative:

to receive using the mobile device receiver an indication of channel quality from the mobile devices included in the group of feedback mobile devices and

to determine, prior to transmitting the indication that the mobile device is volunteering, that no members of the group of feedback mobile devices are adjacent the mobile device and have a lower channel quality.

8. An article of manufacture comprising a non-transitory, processor-readable storage medium storing one or more software programs which when executed by one or more processors performs the steps of the method of claim 3 .
