Method and apparatus for a signal power control in a wireless communication system |
摘要 |
The invention provides a signal power control method and apparatus for a wireless system to control the power level of a received signal transmitted over a radio link so as to counteract transmission impairments caused by environment variations and maintain the reliability of the radio link. The signal power control of this invention serves to control the transmit power used for transmission and adjust the position of the receiver dynamic range so that the received signal can always be optimally received. In a preferred embodiment, the invention is incorporated in a broadband wireless access (BWA) time division multiplex access (TDMA) system to maintain the reliability of an upstream radio link connecting a base transceiver station (BTS) with multiple customer premises equipment (CPE) units. In the preferred embodiment, power control messages are exchanged between the BTS and the CPE units based on the international telecommunications union (ITU) R112 local multipoint distribution service (LMSD) standard for effecting the signal power control of the present invention. |
