Abstract

Technology for adapting uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configurations in a heterogeneous network (HetNet) is disclosed. One method can include a reference enhanced Node B (eNB) determining a preferred adaptive UL-DL configuration. The eNB can receive node configuration information for at least one neighboring node. The eNB can reconfigure an adaptive UL-DL configuration for at least one of the reference eNB and the at least one neighboring node based on the node configuration information and sounding reference signal (SRS) subframe scheduling of the reference eNB and the at least one neighboring eNB.
