Embodiment Construction

[0094] Embodiments of the present invention will be described below with reference to the drawings. In addition, in the following description, among the communication devices existing in the communication network, when collectively referring to the base station and the control station, they are referred to as "master stations" to distinguish them from terminals that are slave stations.

[0095] In an embodiment of the radio communication system implementing the present invention described below, first, in the master station or the terminal, the attribute of the terminal or the attribute of the line between the master station and the terminal is recognized. As this attribute, the following information is used.

[0096] (1) Information indicating whether the terminal is a fixed terminal or a mobile terminal

[0097] (2) Information indicating the remaining power supply level of the terminal

[0098] (3) Indicates the communication priority of the terminal and the priority of t...

Abstract

The use efficiency of radio resources in the quality management of a radio channel in a wireless communication system is improved. A monitoring unit 2 monitors a quality of a radio channel established between a master station and a terminal device. An identification unit 3 identifies attribute information representing an attribute of the terminal device or an attribute of a connection designated in a communication between the master station and the terminal device. On the basis of both a result of monitoring the quality of the radio channel by the monitoring unit 2 and a result of identifying the attribute information by the identification unit 3, a control unit 4 determines a reporting cycle in which management information is cyclically reported to a communication partner in order to manage the quality of the radio channel.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to wireless channel quality management technology in the wireless communication system. Background technique [0002] There is a wireless communication system that transmits and receives signals between a base station (master station) and a terminal (slave station). In this system, the following work is usually required: In order to enable the base station to receive the uplink signal sent by the terminal with a certain receiving power, control the transmission power and timing; The channel quality is notified to the base station. [0003] Among them, through the control of the uplink transmission power, the transmission power of the terminals near the base station is reduced to reduce the interference to other terminal communications and save power. On the other hand, the transmission power from the base station to the remote terminal is increased to improve The intensity of r...
