Based on the monitored performance, one or both of operation of a particular transmit path from the multiple transmit paths may be controlled and assigning of a plurality of segments, in a frequency spectrum that is used for transmission of signals, to the multiple transmit paths. Controlling operation of the particular transmit path may comprise disabling or enabling that transmit path. The frequency spectrum may be segmented, into the plurality of segment, such that each of the segments is uniformly sized, or at least one of the segments is sized differently. The segmenting may be performed to maintain compliance and/or compatibility with one or more protocols or standards applicable to said transmission.

Abstract: Systems and methods are provided for implementing and using multiband transceivers. In a transmitter that comprises a plurality of transmit paths, a frequency spectrum that is used for transmission may be assigned to the plurality of transmit paths. Performance in each of the plurality of transmit paths may be monitored during transmission of signals, and based on the monitored performance, at least one of segmentation of the frequency spectrum and assignment of the segments to the plurality of transmit paths may be dynamically modified. Performance monitoring may be based on spectrum usage, peak to average power ratio (PAPR), and/or performance related criteria (e.g., threshold, timeout duration, etc.). Modifying operation of a transmit path may comprise disabling or enabling that transmit path. The frequency spectrum may be segmented such that each of the segments is uniformly sized, or such that at least one of the segments is sized differently.

Abstract: Systems and methods are provided for utilizing remote spectrum analysis of transmit bands in communication systems. A transmit band spectrum corresponding to a transmit band used in transmitting signals may be captured. The captured transmit band spectrum may be processed, and based on such processing presence of noise, distortion, interference, etc. in the transmit band spectrum may be detected, wherein the noise, distortion, interference, etc. may be introduced by one or more other systems sharing a medium used in the transmitting of the signals. One or more characteristic associated with each instance of detected noise, distortion, interference, etc. may be determined. Reporting information, related to the detection of noise, distortion, interference, etc. and/or to the determined one or more characteristics associated with each instance of detected noise, distortion, interference, etc., may be determined, and the reported information may be sent to at least one remote system.
