  • Facilitating noise estimation in wireless communication
    Patent number: 9319893
    Abstract: 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.
