Facilitating noise estimation in wireless communication

An apparatus for wireless communication, comprising:

• means for identifying time-frequency resources provided for an uplink wireless signal according to a wireless network protocol;
• means for identifying signal dimensions that are orthogonal or pseudo-orthogonal to permitted uplink wireless signal dimensions on the time-frequency resources, and that are not assigned for uplink transmission on the time-frequency resources in a geographic region served by the apparatus, the signal dimensions comprising a root sequence and each cyclic shift of the root sequence;
• and
• means for estimating noise on the time-frequency resources based on analysis of at least one of the root sequence or the cyclic shift of the root sequence.

An apparatus for wireless communication, comprising a processor configured to execute computer executable modules stored in memory, the modules including:

• a first module that identifies time-frequency resources provided for an uplink wireless signal according to a wireless network protocol;
• a second module that identifies signal dimensions that are orthogonal or pseudo-orthogonal to permitted uplink wireless signal dimensions on the time-frequency resources, and that are not assigned for uplink transmission on the time-frequency resources in a geographic region served by a base station, the signal dimensions comprising a root sequence and each cyclic shift of the root sequence;
• and
• a third module that estimates noise on the time-frequency resources based on analysis of at least one of the root sequence or the cyclic shift of the root sequence.
