Claim:
1. A method at a User Equipment (UE) comprising: transmitting a Power Preference Indication (PPI) request to a network element; receiving from the network element a PPI signal in response to transmitting the PPI request; determining that a current radio resource configuration of the UE is one of a power optimized type or a normal type that is not power optimized based on the PPI signal; responsive to the UE determining that the current radio resource configuration of the UE is the normal type, starting a prohibit timer; prohibiting the UE from sending additional PPI requests for a radio resource configuration of the power optimized type until expiration of the prohibit timer, wherein determining that the current radio resource configuration is the normal type comprises receiving an indication as part of configuring the UE during a radio resource control (RRC) configuration procedure; and refraining the UE from sending additional PPI requests for a radio resource configuration of the normal type for a predetermined amount of time after determining that the UE's current radio resource configuration has changed from the normal type to the power optimized type, wherein the prohibit timer runs for a longer duration than the predetermined amount of time.
