Method for transmit power control in a communication system

摘要

A plurality of secondary stations (10a through 10n) are coupled to a primary station (8) by way of a shared communication medium (15, 16). The secondary stations (10a through 10n) sends information to the primary channel on the upstream channel. The primary station sending information to the secondary stations (10a through 10n) on a downstream channel. The power level of a secondary station (10n) is set at the power level stored in secondary station memory (55). The secondary station (10n) transmits a message to the primary station on the upstream channel. The primary station (8) receives the message, determines the power level of the received message, and sets the power level of the secondary device to the nominal power level.
