US 2003/0190926 A1 · Method and apparatus for transmitting data in a packet data communication system

Abstract

A wireless communication system transmits data over a first link from a first mobile station (MS) to an infrastructure at a first speaker link power level, and over a second link from the infrastructure to a second MS at a first listener link power level, during a first time period. Each of the first power levels is designed to avoid the need for retransmissions of erroneously received data. Upon expiration of the first time period, data is transmitted over the first and second links at reduced power levels, which transmissions include retransmissions of erroneously received data. Error targets used in the transmission of data may also be adjusted after expiration of the first time period. In addition, the power levels and error rate targets may be individually adjusted on a link-by-link basis based on the RF loading of each link and/or based on error metrics determined for each link.

Claims21

Dependent claims

A method for transmitting data comprising steps of:

transmitting, by a first communication device, a first set of data at a first power level during a first time period, wherein the first power level is such that the first set of data is received by a second communication device at an acceptable error rate without utilizing a retransmission of a portion of the first set of data;
transmitting, by the first communication device, a second set of data at a second power level upon expiration of the first time period, wherein the second power level is less than the first power level;
and
when a portion of the second set of data is erroneously received by the second communication device, retransmitting the erroneously received portion.

1 more element

A method for transmitting data in a wireless communication system, wherein the communication system comprises a first wireless communication device, a wireless infrastructure in communication with the first communication device via a first reverse link and a first forward link, and a second wireless communication device in communication with the infrastructure via a second reverse link and a second forward link, the method comprising steps of:

determining a first error metric corresponding the first reverse link;
determining a second error metric corresponding the first forward link;
and
determining an acceptable frame error rate of one or more of the first reverse link, and the second forward link based on the first error metric and the second error metric.
