    摘要： Methods, systems, and devices for increasing reverse link throughput by coordination of multiple wireless systems using reverse link blanking are provided. Some embodiments involve utilizing the bandwidth of one carrier bandwidth that partially overlaps with the bandwidth of another carrier bandwidth. This overlap may create interference. Different indicators may be utilized to prompt a device, such as a mobile device, to coordinate reverse link transmission blanking on at least one of the carrier bandwidths to increase throughput for the other overlapping carrier bandwidth. For example, a base station may transmit such an indicator to the mobile device to prompt the transmission blanking. Some embodiments also include increasing transmission power for the overlapping carrier bandwidth during the transmission blanking of other carrier bandwidth. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform.

    摘要： In embodiments, an adaptive tone erasure technique is applied to orthogonal frequency division multiplexing (OFDM) communications, such as ECMA-368 standard ultra-wideband (UWB) communications. A transmitter obtains jammed sub-carrier information and calculates an erasure mask. The jammed sub-carriers are nulled before transmitting to a receiver. In accordance with the erasure mask, bits falling on the jammed sub-carriers are replaced by erasure bits before interleaving, keeping the interleaver block size constant notwithstanding variations in the number of the jammed sub-carriers. The receiver also obtains the jammed sub-carrier information and the erasure mask. After the receiver deinterleaves the constant size blocks, it decodes the data without the erasure bits. The transmitter may detect the jammed sub-carriers itself, or obtain the information from the receiver. The receiver similarly may detect the jammed sub-carriers itself, or obtain the information from the transmitter.
