Abstract
This application provides an uplink transmit power determining method, a related network device and storage medium. In the method, a terminal determines an uplink transmit power based on the repetition count of the UCI. (uplink control information) it receives from a network device. The repetition count of the UCI on a user side is adaptively configured based on a PL(path loss), an interference the and the low coverage level for a user currently accessing at a high coverage level so that a transmit power of the UCI is controlled and an avalanche effect caused by always selecting full-power uplink transmission is avoided.
Claims17
An uplink transmit power determining method, wherein the method comprises:
- receiving a power headroom report (PHR) reported by a terminal;
- obtaining a current path loss (PL) of the terminal based on the PHR;
- determining, based on the PL and an obtained interference margin, a repetition count of uplink control information (UCI) of the terminal;
- and
- sending the repetition count of the UCI to the terminal, wherein the repetition count of the UCI is used to determine an uplink transmit power;
- wherein the determining, based on the PL and an obtained interference margin, a repetition count of UCI of the terminal comprises:
- comparing a sum of the PL and the interference margin with a preset threshold;
- and
- if the sum of the PL and the interference margin is greater than the threshold, determining the repetition count of the UCI based on a high coverage level;
- or
- if the sum of the PL and the interference margin is less than the threshold, determining the repetition count of the UCI based on a low coverage level.
A network device, comprising:
- a receiver, configured to receive a power headroom report (PHR) reported by a terminal;
- a processing circuit, configured to obtain a current path loss (PL) of the terminal based on the PHR, wherein
- the processing circuit is further configured to determine, based on the PL and an obtained interference margin, a repetition count of uplink control information (UCI) of the terminal;
- and
- a transmitter, configured to send the repetition count of the UCI to the terminal, wherein the repetition count of the UCI is used to determine an uplink transmit power;
- wherein the processing circuit is configured to:
- compare a sum of the PL and the interference margin with a preset threshold;
- and
- if the sum of the PL and the interference margin is greater than the threshold, determine the repetition count of the UCI based on a high coverage level;
- or
- if the sum of the PL and the interference margin is less than the threshold, determine the repetition count of the UCI based on a low coverage level.
