Abstract
A method includes sending wireless data to a receiver node and receiving feedback from the receiver node that identifies a subset of the wireless data that the receiver node failed to receive correctly and that includes a token value as a label for the subset of the wireless data as a group. The method includes constructing retransmission wireless data that includes the subset of the wireless data and the token value. The method includes sending the retransmission wireless data to the receiver node. The receiver node may be a first client device. The method further includes allocating a first set of token values to the first client device and a second set of non-overlapping token values to a second client device in a network. The method includes respectively notifying the first and second client device of the corresponding set of token values for retransmissions requested by the corresponding client device.
