Abstract
Systems and techniques for managing interference between pico cells in a pico cluster. Pico eNodeBs are configured in groups for each of a plurality of UEs, based on factors such as signal to noise ratio and geographic location. All signals from UEs may be measured by all eNodeBs in the cluster, but a pico group decodes packets only of UEs associated with the pico group. Decoded packets are exchanged between pico groups, and when a pico group is unable to decode packets of an associated UE, is uses the decoded packets received in exchanges to reconstruct an interference signal. The interference signal is subtracted from the received signal and the resulting received signal is used to decode the packets of the UE.
