Abstract

A small cell may include a base station that may be co-located with an edge computing device. The edge computing device may be integrated within a small cell base station or be a physically separate module communicatively coupled to and in close proximity with the small cell base station that provides edge computing resources at the small cell. The processing responsibilities associated with received data may be split or divided between the edge computing device and a target mobile device. For example, a portion of data processing may be performed by the edge computing device and the remaining portion of data processing may be performed by the target mobile device. The distribution of processing responsibilities may be based on radio link conditions or conditions (e.g., power state or processing capabilities) associated with the target mobile device.
