Abstract: A method for deactivated secondary Component Carrier (CC) measurement in a communications apparatus providing wireless communications services via a first CC in a wireless network includes: determining a switch timing to perform bandwidth extension or frequency adjustment required for performing a deactivated secondary CC measurement; extending an operation bandwidth or adjusting a center frequency of at least one signal processing component included in the communications apparatus at the switch timing, wherein an operation band defined by the operation bandwidth and the center frequency of the signal processing component covers at least a bandwidth of the secondary CC; and performing the deactivated secondary CC measurement after extending the operation bandwidth or adjusting the center frequency. The secondary CC is not able to perform data transmission or reception during a deactivated state.

Abstract: Apparatus and methods are provided for determining AR filter coefficient and numbers of synchronization. In one novel aspect, the AR filter coefficient and times of synchronization are determined based on the temperatures of the oscillator. In one embodiment, the UE determines a temperature drift rate by collecting sets of temperatures before and after the UE in the sleep mode of the CDRX, generates one or more threshold look-up tables and performs an optimization selection based on the temperature drift rate and the one or more threshold of look-up tables, wherein the optimization selection comprising selecting an alpha coefficient and a number of subframes for synchronization. In another embodiment, the optimization selection is further determined based on a subcarrier spacing, and a channel type of being a static channel type and a fading channel type. The UE further performs an on-the-fly oscillator S-curve calibration based on the set of temperatures.

Abstract: A UE in a wireless network performs RRM measurements according to power saving schemes. The UE receives Synchronization Signal Blocks (SSBs), which are broadcast periodically from a base station to a cell served by the base station, and receives additional signal blocks transmitted periodically from the base station. The additional signal blocks and the SSBs use different time-and-frequency resources. The UE performs an RRM measurement according to information received within an RRM measurement window including at least one of the additional signal blocks and a corresponding one of the SSBs. Additionally or alternatively, the UE performs RRM measurements on SSBs with a first cycle period equal to a Discontinuous Reception (DRX) cycle period. In response to an indication that a predefined condition for the RRM measurements is satisfied, the UE performs the RRM measurements with a second cycle period which is at least two times of the first cycle period.
