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 via a first communication link;

    relaying the transmission to a baseband unit device that is remotely coupled to the remote radio unit device via a second communications link; and

    in response to a passing of a latency period without receiving an indication from the baseband unit device that the transmission from the mobile device comprises an error, and based on a result of a determination as to whether the transmission from the mobile device contains the error, sending a message to the mobile device, wherein the message is usable by the mobile device to retransmit the transmission.
