Abstract

An apparatus and method for a base station (BS) in a cellular network for uplink (UL) Joint Reception of Coordinated Multi Point (JR-CoMP) operations, wherein the User Equipment (UE) sends to the serving and coordinating Radio Units (RUs) a first data block, wherein because of different channel qualities, first data block arriving as second data block at serving RU and as third data block at coordinating RU, respectively. The Baseband Unit (BBU) associated with these RUs using two nested HARQ processes: First, a 'fake' HARQ process to combine the separately channel processed second data block with the third data block; then, a real HARQ process to combine the fake HARQ-combined data block with the retransmitted first data block. Fake HARQ uses Chase Combining while real HARQ uses Incremental-Redundancy Combining.
