Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode

Abstract: A user equipment (UE) may reduce a peak to average power ratio (PAPR) ratio for an uplink transmission. The UE may receive an indication of an allowed error vector magnitude (EVM) for each of an uplink data signal, an uplink reference signal, and an uplink control signal from a base station. The base station may determine the allowed EVM based on a signal to noise ratio (SNR) for the UE measured at the base station. The UE may generate one or more uplink signals. The UE may apply a PAPR reduction to the one or more uplink signals based on the allowed EVM corresponding to each of the one or more uplink signals. The UE may transmit the one or more uplink signals to the base station.

Abstract: A transmitting device may reduce a peak to average power ratio (PAPR) ratio by clipping samples that have an amplitude exceeding a threshold. For a downlink transmission, the transmitting device may transmit an incremental peak suppression information message (PSIM) to multiple user equipments (UEs). A UE may receive downlink control information (DCI) indicating a data and a modulation and coding scheme (MCS) for the UE, and at least a first incremental PSIM. The UE may decode at least the first incremental PSIM that is applicable to a MCS lower than or equal to the MCS for the UE. The UE may determine whether to decode one or more subsequent incremental PSIMs based on the MCS for the UE. The UE may apply peak information from the incremental PSIMs to the data channel. The UE may decode the data channel based on the MCS for the UE.
