Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.

Abstract: Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station in wireless communication with the UE, an allocation of time and frequency resources for an uplink transmission of a first communication type associated with a threshold reliability or latency metric. The UE may monitor a control channel for an uplink preemption indication from the base station, the uplink preemption indication indicating whether the UE should transmit the uplink transmission using the first communication type associated with the threshold reliability or latency metric. The UE may then process the uplink transmission based on monitoring the control channel for the uplink preemption indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a first communication, associated with a first traffic type, or a second communication, associated with a second traffic type, as a selected communication for transmission in an overlapping resource, wherein the first communication and the second communication at least partially overlap in time, and wherein the selection is performed based at least in part on a rule; and transmit the selected communication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.

Abstract: A transmitter may allocate resources across multiple links for a transmission to a receiver. The transmitter may transmit a resource grant to the receiver. The transmission may include a data packet allocated across multiple links, and pilot signals on a number of links. The receiver may use an indicator included with the resource grant to trigger measurement of channel quality for links with pilot signals.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with quasi co-located (QCL) associations between a physical uplink control channel and a sounding reference signal (SRS) transmission for at least one time and frequency domain channel parameter. The UE may transmit, in accordance with the QCL association, a control channel transmission via the physical uplink control channel using an antenna port that is quasi co-located with at least one antenna port for transmitting the SRS transmission and transmit, in accordance with the QCL association, the SRS transmission via the at least one antenna port. In another example, the base station may configure the UE with an antenna port association between an SRS transmission and a physical uplink control channel. The UE may transmit the SRS transmission and a control channel transmission in accordance with the antenna port association.

Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink channel multiplexing and waveform selection. Uplink channels to be transmitted from one or more user equipment (UEs) to a base station are multiplexed together or separately into an uplink subframe. Each UE is capable of using different waveforms to transmit different channels. Reference signals are communicated according to an RS pattern, which is symmetric across uplink and downlink channels.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an offset value from a first modulation and coding scheme relating to a first code rate for a payload data transmission. The UE may determine, for a transmission of uplink control information, a second modulation and coding scheme, relating to a second code rate, that is different from the first modulation and coding scheme based at least in part on the offset value. The UE may transmit the uplink control information using the second modulation and coding scheme based at least in part on determining the second modulation and coding scheme. In some aspects, a UE may segment uplink control information. Numerous other aspects are provided.
