Abstract: A method for wireless communications includes determining a time division duplex (TDD) configuration of a non-serving network. The method also includes detecting interference from the non-serving network based at least in part on the TDD configuration of the non-serving network. The method further includes signaling an eNodeB of the interference based at least in part on the detecting.

Abstract: A user equipment (UE) may reduce coexistence issues with one or more radio access technologies (RATs) caused by a bursty interference. The bursty interference may be detected by detecting a number of modes in a measured signal sample and determining when a signal contains a multi-modal distribution based at least in part on the detecting. A coexistence indication is created based at least in part on the determining.

Abstract: Techniques for transmitting data with distributed and centralized scheduling in a multihop relay communication system are described. For distributed scheduling, a relay station may generate and send first channel quality information (CQI) to a base station and receive second CQI from a subscriber station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on the second CQI. For centralized scheduling, the relay station may generate first CQI for the base station, receive second CQI from the subscriber station, and send both CQIs to the base station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on a scheduling decision determined based on the second CQI. Techniques for distributed and centralized power control are also described.

Abstract: Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
