Abstract

The embodiment of the invention discloses a power control method and terminal equipment. The method includes the following steps: receiving configuration information sent by a base station, wherein the configuration information includes uplink power control parameters; estimating the transmitting power of an uplink shared channel of a beam set where the terminal equipment is located according to the uplink power control parameters; calculating the power headroom of the beam set where the terminal equipment is located according to the maximum transmitting power of the terminal equipment and thetransmitting power of the uplink shared channel of the beam set where the terminal equipment is located; generating a power headroom report according to the power headroom of the beam set where the terminal equipment is located, and sending the power headroom report to the base station; and calculating the power headroom of the beam set in a beam domain, and sending the power headroom to the basestation in the form of the power headroom report to ensure that the base station adjusts the power of the terminal equipment side. Based on the above method, the problems of increased interference between the terminal equipment, insufficient resource scheduling or decreased uplink throughput and the like caused by inaccurate power control can be avoided.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, in particular to a power control method and terminal equipment. Background technique [0002] In order for the eNodeB to dynamically allocate appropriate resources for the terminal, the terminal needs to report its power headroom information to the eNodeB. The eNodeB will adjust the current transmit power of the terminal device according to a power headroom report (Power headroom report, PHR for short). However, if the power headroom report sent by the terminal to the base station is inaccurate, it will lead to unreasonable scheduling resources allocated by the base station to the terminal, which will further lead to problems such as increased interference between terminals, insufficient resource scheduling, or reduced uplink throughput. [0003] In order to solve the above problems, in the prior art, the terminal calculates the power headroom (PH) based on the downlink p...
