Abstract
A base transmission signal and an auxiliary transmission signal may be used to (e.g., concurrently) improve a harvesting efficiency of an energy receiver while maintaining a prespecified performance level of an information receiver. An auxiliary transmission signal may be constructed. The construction of the auxiliary transmission signal may be signaled. An auxiliary transmission signal may be adapted. The adaptation of the auxiliary transmission signal may be signaled. An impact of auxiliary transmission signals on an information receiver's performance may be mitigated. One or more narrowband energy harvesting (EH) signals may be used, for example to provide a high peak to average power ratio (PARR) for EH devices (e.g., without significantly impacting overall transmitted signal PARR) characteristics. One or more narrowband auxiliary signals may be used, for example to enhance the PARR characteristics of an information signal sub-band.
