    Abstract: A method for moving between cells by a wireless device includes receiving instructions for the wireless device to measure and report a gradient change value to apply offsets based on a plurality of speed states; identifying a speed state in which a moving speed of the wireless device is included among the plurality of speed states; obtaining an offset mapped to the speed state; first filtering a received wireless signal at a physical layer and second filtering the received wireless signal at a radio resource control layer; calculating the gradient change value corresponding to the obtained offset. The gradient change value indicates a rate of change of received signal strength with a serving cell or a rate of received signal strength difference between a neighbor cell and the serving cell. A portion of the second filtering of the received wireless signal is determined based on the calculated gradient change value.

    Abstract: A method and system for minimizing the battery power consumption of user equipment (UE) during inter-frequency cell detection in a heterogeneous network is disclosed. A serving cell in the heterogeneous network provides a relaxed cell detection indication to the UE on a specified frequency for cell detection. The UE applies the relaxed cell detection for detecting the cells on the specified frequency. During inter-frequency cell detection on specified frequency, the UE discards some normal measurement gaps. The inter-frequency cell detection is delayed as compared to normal cell detection time requirement using the normal measurement gaps. The UE deactivates the relaxed detection indication, upon detecting the inter-frequency cell and performs the continuous RSRP and RSRQ measurements for detected inter-frequency cell using all the normal measurement gaps to meet normal measurement accuracy and measurement reporting requirement.

    Abstract: A dormant/idle mode operation of a plurality of cellular device(s) is offloaded using proximity radio interface to a second device having cellular capability so that a plurality of cellular devices can turn off the radio and baseband circuitry associated with the cellular capability, and save battery power. The second device to which the dormant/idle mode operation is offloaded acts like a proxy device for a plurality of cellular devices to perform at least one of the following functions on behalf of plurality of cellular devices: monitor network page, perform cell re-selection, perform tracking area update, or perform D2D transmission and reception, wherein the second device and the plurality of cellular devices are connected each other through a proximity radio interface.
