US 2017/0325207 A1 · Uplink Allocation Echoing

Abstract

Interference coordination using over the air data is enabled. A UE receives downlink control information including uplink resource allocation. The UE determines whether it is near a cell edge of its serving cell. If so, the UE echoes at least a subset of the allocation information over the air to one or more neighboring base stations. The echo may use a multi-cluster PUSCH approach or a combined PUSCH, PUCCH approach. One or more neighboring base stations receive the echoed allocation data. With the echoed data, the neighboring base stations engage in interference coordination, thereby avoiding delays inherent in non-idea backhaul connections. Other aspects, embodiments, and features are also claimed and described.
