  • UAI assistance information
  • a UE may provide a network information that could be helpful to the network in optimizing performance of the UE.
  • a mechanism referred to as a UE assistance information (UAI) message, allows a UE to indicate such information to network.
  • This information may include, for example, a defined delay budget report, a connected discontinuous reception (CDRX) length, or overheating assistant information.

Alternatively, an adjustment could represent an increase in processing or resources if the UE has sufficient battery life and/or is no longer experiencing overheating.
  • a UAI message may indicate expected adjustments, but there is no definition regarding when the network is to respond, which may be left to implementation (e.g., at the base station) . Lack of definition regarding when to apply an adjustment indicated in a UAI message may lead to a less than optimal result, for example, with an adjustment being implemented too soon resulting in reduced throughput if hardware resources are downgraded, or too late resulting in extended power consumption.
  • the action time generally indicates a point in time for an adjustment indicated in the UAI message to be applied.
  • a UE may indicate an action time as an offset (e.g., in slots or ms) to a current time selected based on one or more factors, such as a current battery state, anticipated end of a file download, or other factors.
  • Including an action time in a UAI message may help increase flexibility, allowing a UE a level of control over when an expected adjustment is to be applied. As a result, an optimal result may be achieved. As an example, indicating an action time may delay application of an adjustment in order to maintain throughput before hardware resources are downgraded, allowing download of a file to be completed. As another example, indicating an action time may result in application of a power saving adjustment sooner, extending battery life.
