Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. An unused channel within a television broadcast frequency spectrum is first identified. A downclocked waveform (for data transmission) is then generated by applying a factor to a clock that causes a waveform bandwidth to be reduced from a first bandwidth to a second bandwidth, wherein the second bandwidth of the downclocked waveform is less than a channel bandwidth for the identified unused channel. The downclocked waveform may then be configured so that it coexists with a larger waveform having a third bandwidth that is greater than the channel bandwidth. The downclocked waveform is then wirelessly transmitted from the transmitter device over the identified unused channel.

Abstract: Beamforming may be used in MIMO communication systems to further enhance spectral efficiency. Beamforming refers to beamed transmissions to a single destination (e.g., a station) at a time, to enhance the rate and/or range of transmission. To perform beamforming from a source to one or more destinations, a channel and/or beamforming matrices corresponding to the channel needs to be known at the source, which may be obtained as feedback from the destination. However, the beamforming matrices may not be smooth over frequency as it is fed back from the destination. Therefore, certain aspects of the present disclosure provide beamforming feedback options, resulting in the smoothness of a beamforming matrix.

Abstract: Methods and apparatuses are proposed for supporting one or more user-dependent channel state information (CSI) feedback rates in a downlink spatial division multiple access (SDMA) system. For certain aspects, an access point (AP) may receive a channel evolution feedback from one or more stations and send a request for CSI to the stations whose CSI values need to be updated. For certain aspects, the AP may poll the stations for updated CSI values. For certain aspects, deterministic back-off timers may be assigned to the stations indicating when to send their CSI feedback. The proposed methods may improve system performance.
