Management of modulation and coding scheme implementation

摘要

In an example, packets transmitted over a communication channel from a transmitter are received. Channel state information (CSI) from the received packets are obtained and signal-to-noise (SNR) values of the communication channel are computed based on the obtained CSI. In addition, effective bit error rate (BER) values are determined based on the SNR values, a coherence time period within which the effective BER values of the communication channel remain within a predetermined range is determined, a modulation and coding scheme (MCS) to be implemented by the transmitter is determined based on the effective BER values within the coherence time period, and the determined MCS is transmitted to the transmitter.

1. A method comprising:
receiving packets transmitted over a communication channel from a transmitter; obtaining channel state information (CSI) of the communication channel from the received packets, wherein the CSI indicates conditions of the communication channel; computing signal-to-noise ratio (SNR) values of the communication channel based on the obtained CSI; determining effective bit error rate (BER) values of the communication channel based on the SNR values; determining a coherence time period, wherein the coherence time period is a time duration within which the effective BER values of the communication channel remain within a predetermined range: determining a modulation and coding scheme (MCS) to be implemented by the transmitter based on the effective BER values within the coherence time period; and transmitting the determined MCS to the transmitter.
