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.

The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements.

A user equipment (UE) may receive signaling from a base station that includes an indication of a configuration for measuring cross-link interference (CLI) and an indication of a reference subcarrier spacing (SCS). The configuration may be associated with a slot having more than 14 symbols and may indicate a resource allocation that includes a sounding reference signal (SRS) resource, a CLI resource, or both. The UE may use the SRS resource to measure an SRS and may use the CLI resource to measure a received signal strength indicator (RSSI).

The UE may transmit, to the base station, a report including an indication of the determined CLI level.

Abstract: Aspects are provided allowing a UE to perform early termination of repetitions of an ongoing PUSCH transmission in response to a DCI from a base station indicating whether a prior PUSCH transmission or repetition was successfully decoded. The UE obtains information configuring an uplink data transmission and a repetition of the uplink data transmission. The UE sends the uplink data transmission to a base station. The UE terminates the repetition of the uplink data transmission in response to reception of downlink information in a downlink control channel. Thus, UE power reduction and enhanced resource efficiency may be achieved. Moreover, the repetition is terminated after a time gap following a CORESET where the downlink control channel is received. As a result, a start time for terminating PUSCH repetitions may be configured to accommodate various timing considerations such as dynamic TDD, different numerologies between PDCCH and PUSCH, and multiple PUSCH processing capabilities.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of resources for transmitting a set of uplink shared channel transmissions and a set of demodulation reference signals (DMRSs) having phase coherence across a set of transmission time intervals (TTIs). The UE may receive, from the base station, a control message indicating a cancellation of a first resource of the set of resources. The UE may determine one or more phase-continuity conditions for the set of resources based on receiving the control message indicating the cancellation of the first resource. The UE may transmit, in remaining resources of the set of resources, at least a subset of the set of uplink shared channel transmissions and at least a subset of the set of DMRSs in accordance with the one or more phase-continuity conditions.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for retransmitting a random access channel (RACH) message, for example, based on parameters for initial RACH transmission. For example, a user equipment (UE) transmits an initial transmission of an uplink RACH message with repetition. The UE receives a downlink control information (DCI) scheduling a retransmission of the uplink RACH message with repetition. The UE determines parameters for the retransmission of the uplink RACH message with repetition based, at least in part, on parameters for the initial transmission of the uplink RACH message with repetition. The UE retransmits the uplink RACH message to the network entity with repetition in accordance with the determined parameters.

Abstract: Methods, systems, and devices for wireless communication are described to support phase continuity in uplink transmissions within a bundle interval. In a first example, a user equipment (UE) may determine bundle intervals for an uplink channel transmission based on a transmission time interval (TTI) format pattern and a bundle size. Bundle intervals may start on a next available uplink TTI after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In a second example, the UE may use frequency resources for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval. In a third example, the UE may not bundle some repetitions of the uplink channel transmission in a same bundle interval, and may use different frequency resources for the repetitions, based on one or more phase continuity rules.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for determining, such as by a user equipment (UE), a bundle size for demodulation reference signal (DMRS) bundling for an uplink random access channel (RACH) message sent with repetition and transmitting the uplink RACH message with DMRS bundling according to the determined bundle size. For example, in some aspects of the present disclosure, the uplink RACH message is sent with a number of repetitions and the bundle size is determined as a function of the number of repetitions. In some aspects, the bundle size is determined based on operation band. In some aspects, the bundle size is determined, based on a duplexing mode in which the UE is operating. In some aspects, the bundle size is determined, at least in part, based on signaling from the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to apply demodulation reference signal (DMRS) bundling to uplink transmissions. The UE may transmit multiple uplink transmissions.

Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) to perform demodulation reference signal (DMRS) enhancement whereby the UE may transmit physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) repetitions with different DMRS densities (e.g., a first DMRS density configuration having a first or default DMRS pattern within a transmission time interval (TTI) that is higher than a second DMRS density configuration having fewer DMRSs than the normal DMRS pattern or no DMRSs within the TTI). The UE may identify TTIs (e.g., slots) that satisfy one or more phase continuity rules, and may perform DMRS enhancement in the identified TTIs, and may restart a mapping sequence indicated in the DMRS mapping pattern at each bundle interval boundary or when consecutive uplink symbol periods within a bundling interval do not satisfy a phase continuity condition.

In some aspects, a user equipment (UE) may encode an indication for demodulation reference signal bundling in a physical uplink shared channel (PUSCH) communication based at least in part on whether uplink control information (UCI) other than the indication is to be included in the PUSCH communication. The UE may transmit the PUSCH communication. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for channel repetition. One example method by a user equipment (UE) may include receiving a first indication of one or more first slots that are counted for one or more repetitions of a random access channel (RACH) message and a second indication of a number of the one or more repetitions, each of the repetitions of the RACH message being during a slot available for uplink communication; and transmitting, to a base station, the RACH message and the one or more repetitions in accordance with the first indication and the second indication.
