US 2015/0085729 A1 · Transport Block Size and Channel Condition Assessment Based Power Consumption Reduction for Cellular Communication

Abstract

This disclosure relates to reducing power consumption for cellular communication based on transport block size in combination with channel condition measurements for applications with certain application characteristics. In one embodiment, a transport block size for use for uplink communication with a base station by a wireless device may be selected. The transport block size may provide more robust communication characteristics than required for current channel conditions. The transport block size may be selected based on application characteristics of an application performing the uplink communication. A transmit power for the wireless device to use for the uplink communication may be selected based on the transport block size providing more robust communication characteristics than required for the current channel conditions. In particular, transport power selection may be biased towards a reduced transmit power based on the transport block size providing more robust communication characteristics than required for the current channel conditions.
