Opportunistic retransmission scheme based on dynamic reassignment of downlink resources
In an embodiment, a BS transmits, on a set of resources, a first communication to each of a plurality of UEs. The BS receives ACKs to the transmitted first communications from a first subset of UEs, and determines that a second subset of UEs fails to ACK the transmitted first communication (e.g., via implicit or explicit NACKs). The BS configures a group scheduling message that indicates an allocation of the set of resources to the second subset of UEs (e.g., a different subset of the set of resources being allocated to each UE in the second subset of UEs) based on a predetermined resource reallocation scheme. The BS transmits the group scheduling message to the second subset of UEs, and transmits, on the set of resources, a second communication to each UE in the second subset of UEs in accordance with the indicated allocation from the group scheduling message.
