  • Clock scheme circuit and a mobile double data rate memory using the clock scheme circuit
    Patent number: 12063043
    Abstract: A clock scheme circuit with low power consumption is shown. A local clock generator is coupled to a global clock generator through a global clock trace to receive a global clock signal, and generate a local clock signal based on the global clock signal. The local clock generator uses a frequency multiplier to multiply the frequency of the global clock signal by a multiplication factor of not less than 1. Thus, the global clock signal transferred through the global clock trace can be a lower-frequency signal in comparison with the local clock signal. The power consumption along the global clock trace is considerably reduced.

  • Reporting of best wideband CQI in mobile communications
    Patent number: 12052596
    Abstract: Various solutions pertaining to reporting of best wideband (WB) channel quality indicator (CQI) in mobile communications are described. An apparatus implemented in a user equipment (UE) calculates a value of a modified wideband channel quality indicator (WB-CQI) with respect to a wideband based on CQI values of a subset of subbands of a plurality of subbands in the wideband. The apparatus then reports the modified WB-CQI to a network. In calculating the value of the WB-CQI, the apparatus excludes one or more subbands from the plurality of subbands to result in the subset of subbands used in calculating the value of the WB-CQI. A respective CQI value of each of the excluded one or more subbands is lower than a respective CQI value of each of the subset of subbands.
