An uplink power control method, comprising:
- receiving, by a first base station, a power headroom report (PHR) sent by a terminal, wherein the PHR comprises power headroom (PH) of the terminal in a first serving cell provided by the first base station, a quantity of physical resource blocks PRBs allocated by a second base station to the terminal in a second serving cell provided by the second base station, and PH of the terminal in the second serving cell provided by the second base station;
- and
- controlling, by the first base station and according to the PHR, transmit power of the terminal in the first serving cell provided by the first base station.
An uplink power control method, comprising:
- sending, by a terminal to a first base station, a power headroom report (PHR) for the first base station to control transmit power of the terminal in a first serving cell provided by the first base station, wherein the PHR comprises power headroom (PH) of the terminal in the first serving cell provided by the first base station, a quantity of physical resource blocks PRBs allocated by a second base station to the terminal in a second serving cell provided by the second base station, and PH of the terminal in the second serving cell provided by the second base station;
- and
- adjusting, by the terminal under control of the first base station, the transmit power of the terminal in the first serving cell provided by the first base station.
A base station, comprising:
- a receiving module configured to receive a power headroom report (PHR) sent by a terminal, wherein the PHR comprises power headroom (PH) of the terminal in a serving cell provided by a first base station, a quantity of physical resource blocks PRB s allocated by a second base station to the terminal in a second serving cell provided by the second base station, and PH of the terminal in the second serving cell provided by the second base station;
- and
- a processor connected to the receiving module;
- and
- a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed by the processor, cause the base station to:
- control, according to the PHR, transmit power of the terminal in the first serving cell provided by the first base station.
A terminal, comprising:
- a sending module, configured to send to a first base station a power headroom report (PHR) for the first base station to control transmit power of the terminal in a first serving cell provided by the first base station, wherein the PHR comprises power headroom (PH) of the terminal in the first serving cell provided by the first base station, a quantity of physical resource blocks PRBs allocated by a second base station to the terminal in a second serving cell provided by the second base station, and PH of the terminal in the second serving cell provided by the second base station;
- a processor connected to the sending module;
- and
- a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed by the processor, cause the terminal to:
- adjust, under control of the first base station, the transmit power of the terminal in the first serving cell provided by the first base station.
