发明名称 Power-Aware Link Adaptation in a Wideband CDMA System
摘要 Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating link resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing channel conditions. A combination of transmit parameters that includes a transmit channelization scheme and is designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and one or more channel conditions associated with the data transmission. The channelization scheme includes a number of subchannels to be used and subchannel configuration parameters for each subchannel, such as spreading codes, spreading factors, and subchannel power levels. The combination of transmit parameters may also include a modulation format, coding scheme, and transmit power setting, as well as parameters relating to multiple-antenna transmit schemes.
