PEAK-TO-AVERAGE POWER RATIO MANAGEMENT FOR RELAYED COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described. PAPR may be relevant to managing transmitter power, receiver sensitivity, or both, and transmissions of a particular device may consider various PAPR reduction strategies to manage transmission power at the device. However, relay devices may be configured to forward communications from multiple transmitting devices, and PAPR may not be considered for aggregate signaling via such a relay device. In some examples of the described PAPR management techniques, assisting transmitters may be configured to transmit PAPR reduction signaling that may be received by a relay device, such that an aggregated signal that is received and forwarded by the relay device may have lower PAPR. Additionally, or alternatively, in some examples of the described PAPR management techniques, a relay device itself may inject PAPR reduction signaling into a received signal to reduce PAPR of a transmission by the relay device.
