  • Patent number: 11968068
    Abstract: A transmitting device applies a first MCS to a first set of data tones that overlaps with a first set of PRTs within a plurality of tones, the first set of PRTs being associated with a first PAPR reduction signal. The transmitting device applies a second MCS to a second set of data tones that overlaps with a second set of PRTs within the plurality of tones, the second set of PRTs being associated with a second PAPR reduction signal. The transmitting device can transmit a transmission signal comprising the first set of data tones and the second set of data tones, the transmission signal using a waveform based at least in part on the first PAPR reduction signal and the second PAPR reduction signal.

  • Publication number: 20240129064
    Abstract: Aspects described herein relate to generating multiple repetitions of an uplink signal for transmission, and transmitting the multiple repetitions of the uplink signal, wherein each repetition of the multiple repetitions includes a set of phase tracking reference signals (PTRSs). Other aspects relate to receiving the repetitions, and using the PTRSs to determine a phase difference in the repetitions for performing joint channel estimation.

  • Publication number: 20240098793
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a collision between an access link communication and a sidelink communication. The UE may resolve the conflict based at least in part on a priority associated with the access link communication and a priority associated with the sidelink communication. Numerous other aspects are provided.

  • Patent number: 11916718
    Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.

  • Patent number: 11917689
    Abstract: Aspects of the disclosure relate to random access procedures. In one example, a UE initiates a random access procedure with a base station, and receives a random access response (RAR) message from the base station in response to the initiating of the random access procedure. The UE further determines a redundancy version (RV) pattern comprising a sequence of a plurality of RVs. The UE also transmits an uplink (UL) communication to the base station as part of the random access procedure. The UL communication comprises a plurality of repetitions of a UL message, each repetition being an iteration of the UL message that is configured by applying a respective RV of the plurality of RVs to the UL message based on the sequence. The UE further receives a downlink message from the base station based on the UL message. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 11916716
    Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 8019434
    Abstract: Power supplied to a particular telemetry system of an implantable device having multiple telemetry systems is managed by a state machine. Power to a transceiver of a device is terminated if the particular telemetry system remains dormant or inactive for a programmable period of time and power to the transceiver is turned on if a particular signal is received by the implantable device.

  • Patent number: 7881802
    Abstract: The selection of one communication channel from a plurality of available channels is determined by a state machine. In an automatic selection mode, a first telemetry system has priority over other telemetry systems. A communication session is in progress based on session initiation and termination triggers. An override function allows manual selection of a telemetry system.
