US 2022/0286339 A1 · 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.

Dependent claims

An apparatus for wireless communication, comprising:

a processor;
memory coupled with the processor;
and
instructions stored in the memory and executable by the processor to cause the apparatus to:
evaluate peak-to-average power ratio (PAPR) for communications from a set of user equipments (UEs) for a time interval, wherein the set of UEs communicate with the apparatus via a relay device;
and
transmit, to a transmitting device, an indication of a configuration for PAPR reduction signals that is based at least in part on evaluating the PAPR.
