Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The core idea of ​​the present invention is: when controlling the uplink power of the trunking terminal, according to the user's location, priority and other information, the users are distinguished to perform corresponding power compensation, so that the power control is more flexible, and the needs of different users can be met and optimized. system performance.

[0025] figure 1 It is a schematic flow chart of Embodiment 1 of the present invention, such as figure 1 As shown, this embodiment mainly includes:

[0026] Step 101, the cluster terminal determines itself as an edge user or a central user.

[0027] In this step, it is used to determine whether the terminal is a central user or an edge user, so as to distinguish betwe...

Abstract

The present application discloses a method for controlling uplink power of a cluster terminal, including: the cluster terminal determines itself as an edge user or a central user; when the cluster terminal is an edge user, according to the preset priority parameters of the cluster terminal, according to the preset The set partial compensation strategy sets the current path loss compensation coefficient α for power control, and determines the uplink transmission power of the cluster terminal according to the α; wherein, 0≤α≤1, the partial compensation strategy includes: high priority corresponding The path loss compensation coefficient is greater than or equal to the path loss compensation coefficient corresponding to the low priority; when the cluster terminal is the central user, set the current power control path loss compensation coefficient α to 1, and determine the cluster terminal according to the path loss compensation coefficient α uplink transmit power. The invention can meet the needs of different users and optimize the system performance.

Description

technical field [0001] The present invention relates to trunking communication technology, in particular to an uplink power control method of a trunking terminal. Background technique [0002] Uplink power control in wireless systems is very important. Through uplink power control, on the one hand, various wireless channel losses and fading can be compensated to ensure the quality of uplink transmission data, user connection rate and user experience, and on the other hand, minimize interference within the system and interference to other users , to prolong the battery life of the mobile station. [0003] LTE system power control is mainly used to adapt uplink transmission to different wireless transmission environments, including path loss, shadowing, fast fading, and interference from other users within and between cells. LTE uplink power control makes the power spectral density (Power Spectral Density, PSD, that is, the power per unit bandwidth) of different UEs reaching...
