Abstract: Methods, systems, and devices for wireless communications are described. A first network device (e.g., a base station) may determine, based on one or more transmissions received over a channel and a channel condition of the channel, a configuration for repeating a sequence from multiple sequences over a resource allocation. A second network device (e.g., a UE) may transmit one or more transmissions over a channel to the first network device. The first network device may transmit, to the second network device, an indication of the configuration for repeating the sequence over the resource allocation. The second network device may transmit a first instance of the sequence and a second instance of the sequence based on the configuration. The first network device may perform error correction on the data based on the received first instance of the sequence and the received second instance of the sequence.

Abstract: Aspects presented herein may improve the efficiency and performance of the tone reservation PAPR reduction technique by allocating peak reduction tone based at least in part on a channel condition, such as based on the signal to noise ratio of the channel. In some aspects, a transmitting device measures a signal to noise ratio for a plurality of tones within a frequency resource. The transmitting device selects a location of one or more reserved tones (e.g., peak reduction tones) among one or more tones based at least in part on an SNR for one or more tones. The transmitting device transmits data to a receiving device in a subset of the plurality of tones that does not include the one or more peak reduction tones. Other aspects and features are also disclosed.

Abstract: A UE may be configured to determine a size of the TB for transmission to a base station based on signaling received from the base station for configuration of at least one of a scale factor or a slot aggregation factor associated with size of the TB. The UE may be further configured to transmit, to the base station, information on the TB in at least one slot, the TB being of the determined size. The base station may be configured to transmit, to the UE, the signaling for configuration of at least one of a scale factor or a slot aggregation factor associated with a size of the TB to be used by the UE for transmission. The base station may be further configured to receive, from the UE, information on at least one TB having a size that is based on at least one of the scale factor or the slot aggregation factor.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a set of transmission tones comprising a set of data tones and a set of peak reduction tones (PRTs), wherein the resource allocation indicates locations for the set of data tones and locations for the set of PRTs within a particular bandwidth, wherein the locations for the set of PRTs are arranged relative to the locations for the set of data tones according to a PRT sequence, and wherein the PRT sequence comprises a plurality of contiguous PRTs arranged relative to a plurality of contiguous data tones or a pseudo-random pattern generated using a pseudo-random number generator; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes determining a first configuration for sidelink (SL) communication by a user-equipment (UE), determining a second configuration for uplink (UL) or downlink (DL) communication by the UE, the first configuration and the second configuration being determined to allow the UL or DL communication to overlap in time domain with the SL communication, and transmitting the first configuration and the second configuration to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may communicate with a network entity via a relay UE using one or more radio resource control (RRC) messages that are encapsulated in a dedicated sidelink signaling message directed to the relay UE. The UE may receive, from the network entity via the one or more RRC messages, an access stratum configuration for a sidelink unicast link between the remote UE and the relay UE. The UE may configure the sidelink unicast link based at least in part on the received access stratum configuration. Numerous other aspects are described.

Abstract: Wireless communications devices and methods are adapted to facilitate DMRS sequence grouping. In one example, information is obtained for a transmission scheduled with pi/2 BPSK modulation, the transmission including two or more symbols scheduled for a DMRS (DMRS symbols). Respective DMRS sequences may be identified for each of the DMRS symbols, where each DMRS sequence subsequent to another DMRS sequence is dependent on its immediately preceding DMRS sequence, and the transmission may be sent with the identified DMRS sequences in the two or more DMRS symbols. In one example, a first transmission may be sent to schedule a second transmission from another device with pi/2 BPSK modulation, where the second transmission includes two or more DMRS symbols. The scheduled second transmission may be received with at least one DMRS symbol including a DMRS sequence based on its immediately preceding DMRS sequence. Other aspects, embodiments, and features are also included.
