Abstract
A system and method for reducing latency in a N/ACK system is described. The present system and method reduces latency in a N/ACK system by pre-generating one or more unsolicited backhaul grants to prepare one or more backhaul elements for the receipt and transmission of wireless data. In an embodiment, the present system and method additionally generates backhaul NACK holds for delaying the transmission of a NACK such that a NACK arrive at the UE at a predesignated time, such as at the subframe 12 after the original transmission at the subframe 0.
Claims11
An NACK unsolicited grant generating system, comprising:
- a modem termination system (MTS) receiving device for receiving a Not Acknowledge (NACK) message from centralized Small Cell (cSC);
- and
- an unsolicited grant processor for analyzing the NACK message and generating at least one unsolicited backhaul grant for the retransmission of a previously failed transmission.
An NACK hold generating system, comprising:
- a modem termination system (MTS) receiving device configure in a backhaul communication system for receiving a Not Acknowledge (NACK) message from centralized Small Cell (cSC);
- and
- a NACK hold processor for analyzing the NACK message and generating at least one NACK hold instruction for delaying the transmission for the NACK at one or more of the backhaul communication systems elements.
The system of claim 10, further comprising a NACK reader for decoding and reading at least a portion of the NACK transmitted by the cSC for the purpose of providing NACK data to the unsolicited grant processor.
