Abstract: This application discloses a power control method and apparatus. This application may be applied to a wireless communication system. The method includes: generating first information, where the first information includes precoding information, the precoding information is used to determine an uplink precoding matrix and power control information to be used by a terminal device, and the power control information is used to determine an uplink transmit power of the terminal device; and sending the first information. In this way, signaling overheads can be reduced. Because the power control information is not carried by using a TPC command, precision of the power control information is not limited by the signaling overheads. Therefore, the precision of the power control information determined by using the precoding information may be higher than precision obtained by adjusting the uplink transmit power by using the TPC command.

The GAA FET device includes P-type semiconductor PFET(s) and N-type semiconductor NFET(s) having channels with different crystalline orientation through a substrate.

Abstract: Enhanced-shaped extension region for gate-all-around (GAA) field-effect transistor (FET) devices and related fabrication methods are disclosed. The GAA FET device includes an extension region of semiconductor material coupled from the respective channel to the source/drain region to facilitate forming a conductive channel between the source and the drain regions when the GAA FET device is activated. The area of the extension region between the source/drain regions and the channel forms a series resistance between source/drain regions and the channel. To reduce channel parasitic resistance, the extension region of the GAA FET device has an enhanced extension portion that has an extended height orthogonal to the channel direction. The extension region with its enhanced extension portion has reduced resistance as compared to an extension region not containing the enhanced extension portion, thus reducing channel parasitic resistance of the GAA FET device for improved performance.
