Abstract

Official abstract text for this publication.

Providing for noise estimation in wireless communication, and particularly for access request signals transmitted by a user equipment (UE), is described herein. By way of example, a wireless signal receiver can employ unused signal dimensions of a wireless network for noise estimation. In addition, the unused signal dimensions can be selected for time-frequency resources that are associated with a particular wireless channel, in order to obtain a noise estimate for that channel. By employing unused signal dimensions, a noise measurement is likely to include no other signal transmissions, and provide an accurate estimate of noise on that channel. According to various aspects of the subject disclosure, one or more Chu sequences employed for signal transmissions, root sequences thereof, or one or more cyclic shifts of a root sequence can be employed for the unused signal dimension.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for wireless communication, comprising: identifying a set of time-frequency resources for a random access probe according to a wireless network protocol; identifying at least one unused signal dimension that is orthogonal or pseudo-orthogonal to permitted random access probe dimensions; employing an unused root sequence for the at least one unused signal dimension, the unused root sequence being a root sequence that is not employed for generatin…
