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.

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.

In an aspect, a user equipment (UE) may identify at least one communication resource from a plurality of communication resources for transmitting a positioning report, wherein the plurality of communication resources for transmitting the positioning report have different priorities.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel.

Abstract: Aspects relate to radio link management for a first type of link that is a high reliability, low-latency communication link such as ultra-reliable, low-latency communication (URLLC). Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.

Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.
