Abstract

The power level for uplink data transmission in a wireless communications network utilizing an on-demand multiple access method with a fair queuing service discipline (ODMAFQ) for efficient utilization of the limited bandwidth available in the wireless network is established curing the initial access request message. The power level in a wireless network having a base station and several remote hosts is established by first transmitting a short connection request message to the base station from one of the remote hosts at an initial power level that is set relative to the nominal open loop power level. If the first remote host'"'"'s transmission is unsuccessful, the power level is incremented by a power increment amount that may be predetermined, and the steps of transmitting and incrementing are repeated until the transmission from remote host to base station is successful. Finally, the power level at which transmission is successful is stored and used for further data transmission between that particular remote host and the wireless network base station.

Claims

1. A method for establishing the power level for uplink data transmission via an initial access request message in a wireless communications network, said network having a base station and a plurality of remote hosts, said network employing the On-Demand Multiple Access Fair Queuing protocol, said method comprising the steps, in combination, of:

transmitting a short connection request message from a first one of said remote host at an initial transmit power level that is set relative to a nominal open loop power level;

if the transmission is unsuccessful, incrementing said transmit power level by a power increment amount;

repeating the steps of transmitting and incrementing until the transmission is successful; and

storing the power level at which transmission is successful and using said stored power level for data transmission utilizing said On-Demand Multiple Access Fair Queuing protocol.

2. A method as recited in claim 1 wherein the power increment amount is predetermined.
