Abstract

The invention discloses a power control method based on outage probability and geometric programming, comprising the following steps: S1. Given a data transmission model from an information sender to an information receiver, and constructing a corresponding optimization problem; S2. Giving an optimization problem An upper bound of the outage rate that needs to be described in ; S3. Based on the upper bound of the outage rate constructed, the optimization problem is converted into a geometric programming problem and solved, and power control is realized according to the solution result. The power control method based on outage probability and geometric programming disclosed in the present invention adopts an upper bound of the outage rate closer to reality, allowing stricter average transmission delay restrictions, and the GP algorithm solves the power, and performs power control according to the solution result, which can Minimize the expected value of the power of each block, thereby reducing the total transmission power and reducing energy consumption.

Description

technical field [0001] The invention relates to the communication field, in particular to a power control method based on interruption probability and geometric programming. Background technique [0002] Modern wireless communication networks have high requirements on the reliability and delay of communication systems. However, in order to achieve ultra-reliable and low-latency communication, most systems need to consume large power, so it is particularly important to reduce power consumption through power control. In systems that achieve the above goals through the hybrid automatic repeat request mechanism, power control methods based on outage probability and geometric programming are still to be studied. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a power control method based on outage probability and geometric programming, which can minimize the expected value of the power of each...
