Problems solved by technology

However, providing too much uplink transmit power margin may result in lower maximum data rate for subscriber stations, while providing too small uplink transmit power margin may lead to communication link errors and waste of network capacity

Embodiment Construction

[0025] now refer to figure 1 , generally denoted by 20 a wireless network for transmitting data. The network 20 includes a radio base station 24 and a plurality of subscriber stations 28a, 28b...28n. In the preferred embodiment, wireless base station 24 is connected via a suitable gateway and one or more backhauls, such as T1, T3, E1, E3, OC3 or other suitable landline links, or via satellite or other wireless or microwave The channel link, or through other links suitable as backhaul as will occur to those skilled in the art, is connected to at least one data telecommunications network (not shown), such as a landline based switched data network, packet network or the like.

[0026] A base station 24 communicates with a subscriber station 28, which in this embodiment of the invention is installed at the subscriber's premises, as is common in wireless local loop (WLL) systems, but obviously can also be nomadic or mobile station. The number "n" of subscriber stations served by...

Abstract

A system and method of determining the maximum uplink transmit power of a subscriber station from a remote base station where the subscriber station reports incidents of foldback in its radio to the base station. When the base station receives the report, it reduces the maximum uplink transmit power of the subscriber station. After a period of time lapses without any reports of foldback occurring, the base station increases the maximum uplink transmit power of the subscriber station.

Description

technical field [0001] The present invention relates to the field of power control in wireless systems. More particularly, the invention relates to determining at a base station an estimate of the available uplink transmit power for each subscriber station in communication with the base station. Background technique [0002] In a wireless network comprising at least one base station and a plurality of subscriber stations, the base station is preferably concerned with the transmit power level of each subscriber station in case the network is affected by "near-far" problems and / or similar problems. flat management. In general, allowing a subscriber station to transmit at more power will allow the subscriber station to achieve a higher data rate, but will also interfere with the transmissions of other subscriber stations. The trade-off between overall network efficiency and specific subscriber station performance is carefully managed. [0003] In addition to network limitati...
