Abstract: Embodiments of the present invention provide a method and an apparatus for controlling transmit power of user equipment. The method includes: when total uplink transmit power of user equipment UE exceeds maximum allowed transmit power, calculating a first gain factor according to the maximum allowed transmit power; performing quantization processing on the first gain factor according to a gain factor of a first physical channel, to obtain a second gain factor, where the first physical channel includes a DPCCH2; reducing a gain factor of a second physical channel to the second gain factor, to reduce transmit power of the second physical channel, so that the total uplink transmit power of the UE does not exceed the maximum allowed transmit power, where the second physical channel includes an HS-DPCCH. This reduces a calculation error and improves control accuracy of transmit power.

Abstract: Embodiments of this application provide a method and an apparatus for setting a symbol in a communications system that uses a plurality of subcarrier spacings. The method includes: obtaining, by a terminal, a length of a reference blank symbol, where the length of the reference blank symbol is associated with a first subcarrier spacing, and the first subcarrier spacing is a minimum subcarrier spacing in the plurality of subcarrier spacings; and setting, by the terminal based on the length of the reference blank symbol and time domain information of the reference blank symbol, a blank symbol for a subcarrier corresponding to a second subcarrier spacing in the plurality of subcarrier spacings. According to the method and apparatus for setting a symbol provided in the embodiments of this application, when setting, based on the length of the reference symbol, a blank symbol in a subframe corresponding to a subcarrier used by the terminal, the terminal may set one or more complete symbols as blank symbols. This avoids a case in which a symbol cannot work normally because a part of the symbol is set as a blank symbol, thereby improving spectral efficiency of the system.
