Transmitting data to a collaborative group

摘要

In an embodiment, a location, a type of application, and a probability of transition to a no-coverage area are determined for each of a plurality of wireless devices in communication with an access node, and a collaborative group of wireless devices which have requested a data stream are selected. A first portion of the data stream is sent to each wireless device to synchronize the requested data stream, and at least one additional portion of the data stream is sent to each wireless device, where a number of the at least one additional portions sent to each wireless device is based on a modulation and coding scheme assigned to each wireless device. A mapping table is broadcast to the collaborative group, and the wireless devices exchange the additional portions of the data stream according to the mapping table when the collaborative group transitions to the no-coverage area.

1. A method of transmitting data to a collaborative group, comprising:
determining a location, a type of application, and a probability of transition to a no-coverage area for each of a plurality of wireless devices in communication with an access node; selecting a collaborative group of wireless devices which have requested a data stream from among the plurality of wireless devices based on the location, the type of application, and the probability of transition to a no-coverage area; sending to each wireless device in the collaborative group a first portion of the data stream to synchronize the requested data stream; sending to each wireless device in the collaborative group at least one additional portion of the data stream, wherein a number of the at least one additional portions sent to each wireless device is based on a modulation and coding scheme (MCS) assigned to each wireless device in the collaborative group; broadcasting to the wireless devices in the collaborative group a mapping table; and exchanging among the wireless devices of the collaborative group the additional portions of the data stream according to the mapping table when the collaborative group transitions to the no-coverage area.
