Problems solved by technology

However, in actual situations, due to the base station construction, the specific terrain environment, and the distance between the mobile station of the vehicle and the base station, etc., wireless data may still have the problem of far and near fading during transmission, resulting in sudden loss and loss of data transmission. The increase in retransmission affects the overall data communication rate of the system
Simply increasing the transmission power of the mobile station can reduce the sudden loss and retransmission of data transmission, but the battery consumption is fast, which does not meet the practical requirements

Embodiment Construction

[0012] An embodiment of the method for adaptively adjusting the transmit power of the mobile station in the present invention:

[0013] The mobile station includes a main controller capable of data processing and control, and its transmission power is adjustable by numerical control. In the data processing program of the mobile station, it is necessary to set up a fixed-length record queue consisting of more than five sent records of the sent packets based on experience. In this example, the length of the record queue is determined to be 10 records. The sending record of each packet in the queue has a unit for saving the sending time of the packet and a unit for the number of retransmissions. Initially, the sending time is uniformly recorded as the time of the initialization operation, and the number of retransmissions is uniformly recorded as 1. The value of the maximum number of retransmissions is defined according to the configuration of the system. In this example, the m...

Abstract

A method of self-adaptable adjusting the sending power of the broadcasting station, which is applied to communicate information between a mobile station and a base station when the change of the fast decline and slow decline of a communication signal during the high speed running, according to the recorded values of the sending record queue of the sent groups, calculate the average retransmiting times in order to adjust the output power of the mobile broadcasting station dynamic ally, and then the channels are working in perfect state.

Description

technical field [0001] The invention discloses a method for self-adaptively adjusting the transmitting power of a radio station, which belongs to a control method of a mobile station, and is especially aimed at a method for controlling radio transmitting power of a vehicle using wireless packet switching technology for real-time data communication. Background technique [0002] At present, the trunking communication system combines GSM cellular digital communication and wireless packet switching technology in communication, thus effectively overcoming the instability and easy loss of wireless data transmission. However, in actual situations, due to the base station construction, the specific terrain environment, and the distance between the mobile station of the vehicle and the base station, etc., wireless data may still have the problem of far and near fading during transmission, resulting in sudden loss and loss of data transmission. The increase in retransmission affects ...
