Embodiment Construction

[0023] Generally, the present invention includes systems and methods for improving data transmission performance in a wireless telecommunications system by controlling the increase and decrease of the reverse link data transmission rate.

[0024] refer to figure 1 , shows a part of a wireless communication system according to an embodiment. In this embodiment, the system includes a plurality of access networks (AN) 12 and a plurality of access terminals (AT) 14 . Each access network 12 communicates with access terminals 14 in its vicinity. An access terminal may move within sectors, or may move from a sector associated with one access network to a different sector associated with another access network. The coverage area is sector 16. Although the sector may actually be somewhat irregular and may overlap other sectors, they are depicted in the figure as generally depicted with dashed lines. It should be noted that, for simplicity, only one access network, one access termin...

Abstract

A method and apparatus for determining a data rate for reverse link communications of an access terminal, the method comprising receiving a reverse activation bit (RAB) from an access network in a communication system, and transmitting the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on the filtered RAB value. A continuous flow power level is determined for each rate update from the filtered RAB value. The access terminal maps the continuous flow power level to the actual physical transmission by dithering between the discrete power levels allowed by the physical layer.

Description

[0001] Claiming priority under 35 U.S.C. §119 [0002] This application is a non-provisional application claiming priority to provisional application serial number 60 / 461,756, filed April 11, 2003, and entitled "System and Method for Fluid Power Control of a Reverse Link Communication." technical field [0003] The present invention relates generally to the field of telecommunications, and more particularly to systems and methods for improving the performance of data transmissions in wireless telecommunications systems. Background technique [0004] In a typical wireless voice / data communication system, base stations are associated with coverage areas. This area is called a sector. Mobile stations within a sector can transmit data to and receive data from a base station. Especially in the case of data communications, base stations may be referred to as access networks (also referred to as access points) and mobile stations may also be referred to as access terminals. An a...
