Burst quality of service (QoS) mode uses a higher modulation rate and coding scheme for transmitting data blocks in a short period of time between a transmitting terminal and a user terminal experiencing a channel state above a certain threshold in a wireless communication system. Burst QoS may reduce data transmission time, thereby achieving a higher level of channel efficiency as well as a reduction in the consumption of power. In burst QoS mode, the channel state information (CSI) may be repeatedly measured. When the CSI is above a certain threshold, a higher rate modulation and coding (MC) scheme is used for burst data transmission. After the burst, a short sleep is triggered to reduce power consumption.
