Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a source base station associated with a source master cell group (MCG), a physical uplink shared channel (PUSCH) repetition in one or more slots of the source MCG during a handover of the UE from the source MCG to a target MCG. The UE may perform, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. Numerous other aspects are described.

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. The UE may transmit an indication of whether the UE is able to comply with the request based at least in part on whether the UE is able to maintain phase coherence across the multiple uplink transmissions. Numerous other aspects are provided.

Abstract: Aspects relate to mechanisms for wireless communication devices for tone reservation. A user equipment (UE) receives an indication of one or more peak-reduction tone (PRT) resources for a transmission of one or more signals for a base station. The UE transmits a first signal to the base station on an uplink. The UE transmits a second signal to a relay entity on a sidelink for reception by the base station. The second signal is transmitted on the sidelink utilizing the one or more PRT resources.

Abstract: Aspects described herein relate to providing demodulation reference signal (DMRS) transmissions for channel transmission repetitions. This can include defining DMRS patterns for channel transmission repetitions having a symbol length that is less than a threshold, dropping or deferring channel transmission repetitions that are mapped to a set of uplink symbols that are less than a threshold symbol length, and/or the like.

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.

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 wireless communication device, selects a set of PRTs based on a deterministic pseudo-random tone selection algorithm, such as quadratic sampling, cubic sampling, or Fibonacci-type sampling. The apparatus determines a PAPR reduction waveform for transmission on the PRTs and transmits a data waveform multiplexed with the PAPR reduction waveform on resources corresponding to the resource allocation. Other aspects, embodiments, and features are also claimed and described.

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.

Abstract: A method for wireless communication by a user equipment (UE) includes transmitting, to a base station, a random access preamble to initiate a random access procedure. The method also includes receiving, from the base station based on transmitting the random access preamble, a downlink message comprising a repetition number indicator. The method further includes transmitting a number of repetitions of a physical uplink channel based on the repetition number indicator.
