  • Patent number: 11395241
    Abstract: A wireless transmission parameter adjustment method and a related device. The method includes monitoring a frequency parameter of a cell, determining, in response to detecting that the frequency parameter of the cell increases, a location relationship between a first terminal and an access network device, wherein the first terminal is a terminal camping on the cell, and adjusting a target power parameter of the first terminal according to the location relationship between the first terminal and the access network device, so that a radio remote unit power does not exceed a preset power, where the target power parameter is a power parameter other than a cell-specific reference signal power.

  • Patent number: 9343183
    Abstract: A controller for a memory device has a power control section to control power to a memory element in an operation mode and in a retention mode. A monitoring section receives and monitors error information and a storage section stores a retention parameter. In the operation mode, the power control section causes an operation voltage to be applied to the memory element, and in the retention mode, the power control section causes a time-varying voltage to be applied to the memory. The power control section also causes the voltage across the memory element to change in the retention mode between a first retention voltage and a second retention voltage based on the retention parameter.
