Description
Technical field
The present invention relates to the communications field, in particular to a kind of data repeating method and device, MAC equipment.
Background technology
Mobile communications network faces the growth of terminal data portfolio expansion type, and the structure of 5G networks needs to reach ultrahigh speed
The indexs such as rate, big handling capacity, ultrahigh reliability, ultralow time delay, provide optimal experience to the user, these demands cause mobile network
The service ability and deployment strategy of network all suffer from huge pressure and challenge, on the one hand operator needs to strengthen existing network
Deployment and mechanics of communication, on the other hand wish to accelerate popularization and the network expansion of new technology, so as to reach fast lifting internetworking
The purpose of energy.
In LTE, to ensure that the user plane that is properly received of data introduces two layers of retransmission mechanism：RLC ARQ(Radio Link
Control Automatic Repeat request wireless spread-spectrum technologies arq) and MAC HARQ (Media
Access Control Hybrid Automatic Repeat request medium access control mixed spin system).
In MAC HARQ mechanisms, MAC recipient receives data and judges the correctness of data and then perform data feedback HARQ ACK/
NACK；MAC senders complete the repeating transmission of MAC data and the transmission of new data according to HARQ ACK/NACK；RLC ARQ mechanism
In, RLC recipient detects the integrality received from bottom data, and RLC is notified after loss of data or data exception is detected
ARQ ACK/NACK；RLC senders complete the repeating transmission of RLC data according to data feedback.With eNodeB (Enhanced Node B
Strengthen node B) in downlink data send in two layers of retransmission mechanism process exemplified by, Fig. 1 is two layers of retransmission mechanism in correlation technique
Flow chart.As shown in Figure 1, although two layers of retransmission mechanism greatly increases the possibility of data transfer, protocol function clear layer.
But the data monitoring and feedback for relying on peer protocol layer are retransmitted there are still every layer, therefore higher layer retransmission opportunity is slightly aobvious " late
It is blunt ".Because the succession requirement of higher layer applications data, two layers retransmission mechanism may deferred traffic data passing to application layer in time
The problem of handing over, influencing QoS of survice.
The content of the invention
