Problem Statement
- Rate adaptation through various Transmission Rates (TR) have played an important role in exploiting the instantaneous channel capacity by transmitting bits at a rate that is optimally suited to the current channel conditions.
- A rate adaptation metric, which reflects the channel capacity, is computed at the User Equipment (UE), and is quantized and fed back to the evolved Node B (eNB).
- The UE also provides an Acknowledgement/Negative Acknowledgement (ACK/NACK) response indicating whether packets are successfully decoded by the UE at a particular transmission rate selected by the eNB. Based on the ACK/NACK response and CQI feedback, the eNB adjusts the transmission rate such that QoS parameters are met.
- However, there are multiple QoS parameters such as BLER, throughput, latency, or the like, which need to be optimized.
- Thus, there is a need of having a method which can meet the overall QoS requirements of each UE through a transmission rate predictor having simple architectural and time complexity respectively.
Technology
A method and an apparatus for switching between various transmission rate predictors as a restless MAB problem (refer Fig. 1, 2& 3).
