Abstract
A user equipment (UE), such as a mobile phone, may support multiple power classes. Power classes can define maximum output power levels for uplink transmissions. A base station of a radio access network (RAN) can, based on metrics reported by the UE, dynamically instruct the UE to switch to using a different power class. For example, the base station may instruct the UE to switch from using a first power class with a higher maximum output power to using a second power class with a lower maximum output power, in order to preserve battery life of the UE in situations in which the second power class provides sufficient output power for uplink transmissions to reach the base station.
Claims20
A method, comprising:
- determining, by a base station of a telecommunication network, that a user equipment (UE) supports a first power class and a second power class, wherein the first power class permits the UE to perform uplink transmissions at a higher output power level than the second power class;
- determining, by the base station, weights corresponding with one or more UE metrics;
- determining, by the base station, a weighted combination of the one or more UE metrics based on the weights;
- and
- determining to dynamically change the UE from using the first power class to using the second power class based at least in part on the weighted combination.
A base station of a telecommunication network, comprising:
- one or more processors;
- memory storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- determining that a user equipment (UE) supports a first power class and a second power class, wherein the first power class permits the UE to perform uplink transmissions at a higher output power level than the second power class;
- determining weights corresponding with one or more UE metrics;
- determining a weighted combination of the one or more UE metrics based on the weights;
- and
- determining to dynamically change the UE from using the first power class to using the second power class based at least in part on the weighted combination.
One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors of a radio access network element, cause the one or more processors to perform operations comprising:
- determining, by a base station of a telecommunication network, that a user equipment (UE) supports a first power class and a second power class, wherein the first power class permits the UE to perform uplink transmissions at a higher output power level than the second power class;
- determining, by the base station, weights corresponding with one or more UE metrics;
- determining, by the base station, a weighted combination of the one or more UE metrics based on the weights;
- and
- determining to dynamically change the UE from using the first power class to using the second power class based at least in part on the weighted combination.
