SYSTEM AND METHOD FOR HARQ IN CLOUD RAN WITH LARGE FRONT HAUL LATENCY

摘要

A system is enabled to perform error checking and other HARQ processes at a remote radio unit device in cloud RAN systems that have a large front haul latency. The remote radio unit device performs error checking on transmissions received from a mobile device and sends an acknowledgement (ACK) or negative acknowledgement (NACK) to the mobile device based on whether errors are found.

1. A remote radio unit device, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving a transmission from a mobile device;determining whether the transmission comprises an error; andin response to the determining indicating that the transmission does not comprise the error, sending an acknowledgement to the mobile device and in response to the determining indicating that the transmission does comprise the error, sending a retransmission request to the mobile device.
