Embodiment Construction

[0015] The base station device described in the present invention is based on the traditional 1C7T large base station, and the traditional large base station includes the following parts: a network interface and a baseband processing unit; a modulation and demodulation unit, which is divided into two parts, master and slave, and performs modulation and demodulation of 4 signals respectively And diversity reception; 8-channel RF front-end, including RF transceiver and power amplifier / low noise amplifier module; 8-channel antenna feeder unit. Among them, the network interface and baseband processing unit are responsible for the interface with the network side and the processing of the baseband signal. The main interface between it and the modem unit is the serial transmission data and transmission clock, as well as the serial reception data and reception clock. Since the modem unit is divided into master and slave stations, the interface between the network interface and the base...

Abstract

The PHS base station consists of; network interface and baseband processing unit; radio frequency front end including radio frequency transceiver and power amplifying / low noise amplifying module; and antenna feedback unit. A control unit is added into the network interface and base-band processing unit for controlling the binding mode of base station. When speech traffic is higher, adopts time slot binding, and when speech traffic is lower, adopts antenna binding. The invention also discloses a method for controlling power in base station above.

Description

technical field [0001] The present invention relates to a base station in a mobile communication system, in particular to a base station in a PHS (Personal Handyphone System). Background technique [0002] The PHS system, also known as the "Little Smart" system, is a wireless access system that utilizes the existing PSTN switching network and TDMA synchronous wireless loop technology. It makes full use of the abundant switching resources of the fixed switching network to realize wireless personal communication anytime and anywhere, and it is positioned as the supplement and extension of the fixed telephone. Because it has the characteristics of low cost, convenient network construction, low mobile phone transmission power, clear voice, low call charges, and convenient support for high-speed data services, it has broad market prospects. [0003] Since the PHS system adopts the linear modulation method, this determines that its base station must adopt linear power amplificati...
